A Comprehensive Guide on Key Considerations to Hire Angular Developers

If you have paused on this article, it’s because you are a tech recruiter looking for a solution to the daunting challenge of hiring Angular professionals. Yes, the recruitment market for these experts is overcrowded with surplus hiring demand but scarce talent supply.
What are the ways in which you can ensure that you have hired the right talent? This article will walk you through key aspects to be considered when you hire Angular developers. Let’s get to the point!
Top 5 Tips for Hiring the Best Angular Developers
The foremost pain point in hiring Angular talent is how to skim through the innumerable candidate profiles. Nearly 76% of talent acquisition leaders state that attracting the right talent is their greatest challenge. To overcome this hiring hurdle, follow these 5 tips:
Experience matters
Suppose a resume speaks out loud about the applicant’s qualifications and accreditations; it's not to be considered an ideal match. It's not a sole hiring attribute to screen because qualifications can’t bear fruits with practical exposure. Therefore, look for a proven track record of their professional work history. Experience in building Angular applications and working with its tools, frameworks, and technologies is the key.
Technical proficiency
When you hire AngularJS developers assessing their technical expertise is a potential hiring factor to be screened. Knowledge of technical aspects of the job is a must, along with proficiency in HTML, CSS, JavaScript, and relevant technologies and trends of the Angular framework.
Value soft skills
In the present hiring landscape, there is immense demand for tech geeks with well-rounded tech familiarity and sound soft skills. Non-technical candidate attributes are equally important to excel in their work. For instance, they might have unique ideas to implement, but how is it possible without conveying them to the team and client?
This requires exceptional communication power, critical thinking ability, and a creative mindset. Certain vital soft skills for Angular developers also include problem-solving, attention to detail, time management, organization, etc.
Have a keen eye on work portfolio
When you hire Angular developers, don't turn a blind eye to the significance of work portfolios and references. It plays a huge role in vouching for their quality of work and commitment and ensuring the truthfulness of their resume claims. Therefore, always consider client testimonials, previous employer reviews, ratings, etc., in your hiring decision.
Consider cultural suitability
Always look for a developer who fits your company culture appropriately. The candidate should share the same work ethic to blend seamlessly with your values, beliefs, and culture. A good cultural fit is a passionate and self-motivated individual with a positive attitude to leap your project to new heights with a productive work relationship.
Where to Hire AngularJS Developers in Competitive Recruitment Market
The next question that will blur your mind when you hire AngularJS developers is which is the best platform to find potential candidates. In the fierce competition, you must opt to employ talent partners to ensure you don't make a bad hire and get the highest ROI from the hiring investment.
Talent partners like Uplers will eliminate the hiring hassle for you and prove to be a cost-effective hiring tactic. They help you fill the vacant spot by matchmaking an ideal candidate profile within a 4-step vetting process:
Gather the job description from the client.
Prepare a pre-vetted network of the top 3.5% of Indian remote talent to find a suitable match.
Conduct a virtual interview of shortlisted candidates.
Onboard the finalized hire.
This will save you up to 40% on the hiring costs with talent procurement in 5 working days. You also have a 30-day talent replacement policy if unsatisfied with their performance. Zero hiring gruntwork with superlative remote talent in your team!
Concluding Thoughts
If you keep this guide handy, you can experience an effortless process to hire Angular developers. Finding the right candidate at the right time from the right place is of the essence in the hiring funnel.

3 decades of Queer Women making Herstory through Music

Written for Pink Washed Zine issue #3
by Raquel Silva aka Raquel Smith-Cave
I turned 30 this year, more precisely last August and it’s also been 12 years since I had my first girlfriend. When I started thinking about my queerness more seriously back in 2005/2006 I quickly realized how it wasn’t that usual for girls to be fascinated by Linda Perry in boxer shorts and combat boots like I was at 5 years old. My mom says 4 Non Blondes “What’s up” was my favorite song back then and she even bought the CD so I could listen to it on repeat and not just wait for the video to magically appear on the TV. Thanks Ma!
Through my teenage years I had “Baby Can I Hold You” by Tracy Chapman constantly playing in my head. Mind you, I always have a song in my mind and I burst into singing at the most unexpected times, it’s mostly an unconscious act which can be embarrassing in front of people who don’t know me well. Honestly I don’t care much, it’s just a part of my nature and if I’m not murmuring or humming some melody it usually means there’s something wrong. So at around 15/16 I remember starting to sing the chorus for “But you can say baby…” out of nowhere in school breaks or while walking home. This happened constantly and exactly why my brain was stuck with this melody was a complete mystery to me. Maybe I heard it in passing or on the radio…? I could never find the answer but I did buy Tracy’s self-titled vinyl this year during Record Store Day and discovered it was released exactly 30 years ago. It’s a precious record, her voice is warm and familiar and her guitar is so soothing to the soul. I think I finally answered my teenage self on all that musical haunting.
Cássia Eller is a Brazilian artist who made the 90s a really wholesome, magical, golden time for every lesbian in love with husky voices. Her hit song “Malandragem” was part of this series called Malhação but I only found out she was the mystical singer behind that iconic childhood tune years after listening to it on the show. She tragically died in 2001 and even after that she still created major impact in society, when her longtime girlfriend won custody of their son, after battling against Cássia’s father who had never cared about his daughter until money was involved. Cássia was a shy person who became a complete lion on stage. Humble and almost too pure to handle the hype. She just wanted to sing to people and exorcise her demons while making others happy. Which she did and so much more. Her legacy is tremendous, as it still resonates with so many of us today and the world hasn’t really witnessed anyone quite as ingenious as her ever since.
It’s 2007 and I’m watching a live concert in a Portuguese music festival on TV featuring a wild ass singer with the screaming voice of my wildest grrrl dreams. It’s The Gossip! And Beth Ditto is rolling around the stage, singing her lungs out in front of a pretty chill crowd. I wanted to BE THERE. I probably discovered Gossip’s music through CSS who I was obsessed with at the time or probably from watching The L Word. The truth is: the more intrigued I was by the words of this fat, dyke, goddess the more comfortable I felt about my own identity. I was fat for most of my childhood and got bullied for it on a regular basis, just part of being in an all-girls catholic school life I guess. At 13 someone called me “Fufa” which is basically “Dyke” in Portuguese and it was the most traumatic experience ever. Years later I wish I could have thanked the girl who bullied me out of a closet I wasn’t even aware I was in. I don’t believe I was ever in the closet though. Honestly, falling in love with a girl was just as natural as having crushes on boys. It was just another question I had finally found an answer for. Beth Ditto’s pride in her queerness and blatant attraction to butch people while being a proud femme, fat, dyke made me feel represented in a way I hadn’t seen myself before and ok with my own desires. Ditto!
The first glance of The L Word I watched I didn’t really enjoyed. The image was dark and the plot seemed so tragic. It was Jenny somewhere in the first season. After one year I finally watched the whole 2 or 3 seasons that were out by then. Tegan and Sara play in one episode and are featured in the soundtrack, which I still go back to sometimes to remember really great tunes. What a blessing to have Tegan and Sara guide you through your first acid trip and “coming out of that closet” am I right Dana? (RIP) My love affair with Canadian people started right there with Tegan’s goofiness and Sara’s witty remarks. By 2007 “The Con” came out and became a staple to the LBGTQ+ community. So much so that the band released a special covers album last year, with many queer artists recreating those magnificent songs. In the records that followed their sound was purposefully re directed to more pop melodies which I couldn’t relate to anymore. They did make good use of their huge platform by launching the Tegan and Sara foundation, which fights for LGBTQ girls and women all over the world with the help of some amazing queer people.
The other tiny Canadian who owns my heart is Ellen Page. Ever since Juno, my gaydar was just screaming out loud in every direction possible and I’m so happy that she is now able to be herself freely. Just like Juno, my musical top 3 included Patti Smith and Iggy Pop… but not The Runaways. For me it’s actually Nick Cave. I never gave too much attention to The Runaways, though I knew about Joan Jett and her extremely queer badass persona from being a teenager obsessed with punk rock and riot grrrl herstory. Until Kristen Stewart got cast to play Joan for The Runaways movie and I finally listened to their 70s records. I fell in love with Kristen and Dakota’s version of “Dead End Justice” as well as the original. Gaystew was born to play that part. Just last week I saw Bad Reputation, a documentary about Joan’s life with lots of awesome people speaking about how incredible she is, as both a pioneer for women in rock’n roll and an advocate for human and animal rights. At 60 she’s still rocking the fuck out of leather pants, inspiring kids to start bands, making everyone smitten by her confidence and flipping the finger to the all the hypocritical social definitions of gender, sex and music.
It’s really difficult to write about Janelle Monáe. Not because I don’t have words but mostly because I have too many. Janelle caught my eye and ears with “Tightrope” where she’s prancing around wearing her uniform, as she proudly used to talk about her suit, an homage to her working class parents and Kansas City upbringing. I saw her live at the end of 2010, at a winter festival, where all my other friends went on to watch Sting’s daughter I Blame Coco and I stood front row waiting for Janelle. It was life changing. She danced, jumped, screamed and even painted something into a blank canvas throughout the whole set. Her band was impeccably orchestrated and the show was extremely cinematic, since many of Janelle’s inspirations are from sci-fi movies. Her music is layered and complex just like her personality. Over the years she has been extremely mysterious, one of the things I appreciated the most about her. This year that changed. After much speculation in the media, she said in an interview she’s pansexual, as someone who has had relationships with men and women, that’s how she identifies more comfortably. Above all she’s an artist with a very specific vision and talent, carving the path for Afrofuturism; to create space for black people but especially queer POC to conquer over the systematic racism, lack of opportunities and prejudice in our society. Her new record “Dirty Computer” is the materialization of that evolution, the most “Janelle” album ever. Covering everything from sexual freedom to political issues while using a pop funky beat. Reminiscing one of her heroes, Prince, who became a friend and mentor before passing away in 2016. And all I want for 2019 is to be in the same room as Janelle and take on another voyage dans la lune with all the other androids.
Annie Clark has also played around with the idea of being an alien or a cyborg, especially on her self-titled album from 2014. That’s when I saw her live for the time and I had to give into my friend’s obsession with her music. Last year St. Vincent released “Masseduction”, an almost perfect record, in my opinion. The song with the same title is most definitely an anthem for our generation “I can’t turn off what turns me on…” and after a long relationship with model/actress Cara Delevingne or that summer fling with Kristen Stewart, it was clear, Annie is queer. (Pun so intended) While songs like “New York” or “Los Ageless” can be associated to both of those relationships, Annie’s talent as an exquisite guitar player, fearless innovative sounds and unique live shows, have made her the intergalactic rock Goddess of our queer dreams.
Widely inspired by Annie Clark is my next musical Queeroe. Mackenzie Scott aka Torres. There’s something about debut albums that I really love and Torres self-titled LP from 2013 is definitely in my top favorites list. It’s really fucking sad music with raw emotion, as you can hear in “Honey”, “Jealousy and I” or “When Winter’s over”. Her second album “Sprinter” showed a very exciting evolution in her sound but it’s “Three Futures” from 2017 that encapsulates Mackenzie’s desire towards experimenting with her sexuality in a more explicit way. As seen in the video for the first single where she takes on gender roles as both feminine and masculine characters who are living the dreadful “American Dream”. Plus the cover picture for that record is her staring at a semi naked woman on a pole, marking 2017 as very gay year for music.
Laura Jane Grace’s voice first made waves through my ears because of the collab Against Me! did with Tegan Quin back in 2007 for the single “Borne On The FM Waves Of The Heart”. The song didn’t stick to me that long and although I had heard Against Me! was my kind of band I never took the time to really listen to them. Until 2014, when “Transgender Dysphoria Blues” was released and it rapidly became one of the most important records of my life. I started watching many interviews with Laura Jane about the struggles of coming out as a trans woman in this fucked up world, specifically while being part of the punk scene, where there’s not much space for anything other than toxic masculinity. I related to Laura’s journey and with every single lyrics on “True trans soul rebel” since it felt like the most authentic punk anthem I had heard in a while. I went to their first ever gig in Portugal in 2015 and screamed as much as I could surrounded by my family of misfits, all wearing black and their heart tattoos on their sleeves. I dug into Against Me! discography but other than the single “I was a teenage anarchist” which I already knew, nothing got me hooked as much as “Transgender Dysphoria Blues” did. Laura Jane’s name is very much appropriate, for her Grace is felt through her screams as much as her written words, something I found fascinating while reading her auto biography: “Tranny: Confessions of Punk Rock's Most Infamous Anarchist Sellout”. I loved every page of it, with original diary pieces, she takes us on a wild precious ride from her childhood and family issues to all the drama in the music industry or the tribulations of managing a band in this time and age. There’s really nothing more punk rock than being yourself and Laura Jane does it with so much effortless coolness and Grace.
I tried not to listen to Courtney Barnett for months. I had seen the hype around her but didn’t feel quite ready to embark in that journey and my queers did I regret it… She played at Primavera Sound Porto in 2015 and I started listening to her on loop only weeks after that. The heartbreaking part is that I was also at that festival. The good part is that she came back in 2016 to another festival in Lisbon and I was there just for her (and Father John Misty). Which felt like the stars had aligned with my musical desires. She’s unapologetically herself but not in the way that you would say so about Cardi B for example. She’s wickedly smart with her words and unexpectedly brutal with her chords, right before she opens her mouth she looks like the sweetest person you will ever meet and after you are transported to her own island, full of genius puns, sarcastic inputs about daily life or the state of the world. My favorite verse is from “Pedestrian at best” and I almost got it tattooed… “Give me all your money and I’ll make some origami honey”. Which to me roughly translates to: Fuck Capitalism! She’s also very open about her long term relationship with her wife and fellow musician Jen Cloher, making them the ultimate indie rock’s queer power couple.
2016 was the darkest year of my life. I stopped listening to music for months, stopped sleeping and my panic attacks would strike me even if I was in the middle of a busy street. It was scary to lose myself in such dark thoughts but then one day I listened to Shura’s song “Too shy” and felt like a little bit of me was alive again. Her debut album “Nothing’s real” came out around that time and her lyrics for the title song were exactly what I felt through my depression. In this song she is writing about her own experience with a panic attack that makes you feel like dying. And they do. “Too Shy” is a beautiful tune about unrequited love because you are simply too fucking shy to ever go for it and ask your crush on a date. Being shy and anxious almost always go hand in hand, as an awkward, quiet, weird introvert myself, discovering Shura’s songs and story gave me hope and made me gather the lost pieces of my own identity, leaving all the pain, shame and constant anxiety behind. Music really is medicine for the soul.
Julien Baker also has one of the best debut albums I’ve ever heard. Personally, it’s very special because it marks the beginning of my current relationship, as my girlfriend surprised me with Julien’s “Sprained Ankle” vinyl just weeks after we started dating. That vinyl did not leave my record player for the last months of 2016 and whenever I listen to it now, I am instantly transported to that moment in time. I was finally getting back on my feet and everything was falling into place, Julien’s gigantic voice echoed my natural melancholy, embracing my demons with a new found strength. I’ve seen her twice, both times a very out of body experience and had the pleasure to let her know how much her music has helped me. We hugged, talked and she even has the zine I make (CuntRoll) in her living room table because she likes it so much. She is someone I could definitely see myself hanging out in my group of friends and that’s what I love the most about this new generation of artists, who aren’t trying to be something they’re not for the sake of money or exposure. They embrace who they are and let the world decide if they wanna take it or leave it. And that’s exactly what we need right now, to accept and embrace people for who they are and the art they make. So we can all to the same in our own lives.
“Yeah I’ve got it I’m a man now…” are the verses that got stuck with me for weeks after listening to Christine and The Queens single “iT”. Yes, the capital T is on purpose as it represents testosterone, the hormone used by many Trans AFAB people to start the process of becoming more themselves. This androgynous handsome French creature original name is Heloise and since her worldwide success with her first record “Chaleur Humaine” she has shredded so many stereotypes through her music, her dancing and her style. I hate comparing artists but some people call her “ the French Michael Jackson” for a reason. My chin dropped while watching her cover for Beyonce’s “Sorry” which she transformed into her own song like it’s nobody’s business (please go watch it asap). This year she blessed as with her second LP just called “Chris” inviting the world to be a little bit closer to her. Chris is her nickname and presents us with a new image for Heloise, embracing her masculine vibe more than ever before, with short hair, loose clothing and talking proudly about queer issues in many interviews. The video for the single “5 dollars” is the epitome of gender fucking and the reason why I am even gayer now tbh. (You should watch that also!) The future is genderqueer.
I stayed away from the hype of “Girls like Girls” back in 2015 because I’m mostly suspicious of pop artists using gay stories to go with the trend of pink washing, ie Katy Perry “I kissed a girl” is a fucking jam but also really fucking problematic, coming from a cis het white female who has no idea the struggles of being queer. Hayley Kiyoko is most definitely not one of those artists though, as she has slowly but certainly become the Lesbian Jesus we’ve all been praying for. With “Curious” she let us know there’s a new fucking boss in town and she’s so fucking gay. What a time to be alive, 20gayteen is real and we are here to witness it all. Hayley’s not the greatest singer in the world, but she uses the best of her skills to give voice to all the kids who struggled with feeling alienated because they couldn’t fit in anywhere. She creates videos which are more like short stories, where she not only acts, but also writes and directs with her own team, never compromising her vision to tell the stories she wants to tell. Stories that resonate with so many queer people and we all know how important representation is, especially coming from an authentic source. To have such a person in the mainstream is what Tegan and Sara were thriving for a few years ago but the result wasn’t very genuine, something that doesn’t happen with Hayley’s songs. Her album “Expectations” doesn’t have big hits, other than “Feelings and “Curious” but it’s the debut album of someone with a huge potential and vision to take up the space for ourselves to tell our own stories and no one else.
Linn Da Quebrada is the musical Goddess of the moment. Eloquent, inspiring, caustic, no one is left indifferent after listening to her. And that's exactly what she wants, to leave us on our tiptoes waiting to be carried away by words of pleasure, empowerment, trans feminism and especially so much self-love. Each verse is a lyrical genius clapback in the face of this transphobic, sexist and racist society. Prejudices that kill so many queer people of color in Brazil every year. Her existence is transforming, rewriting the HERSTORY of the world and of her country, through the re-appropriation of funk, where SHE finally gets to be the protagonist of her own story and that courage surpasses linguistic or cultural barriers. In 2017 she released her first album “Pajubá” after a very successful crowdfunding campaign and also has her own documentary called “Bixa Travesty” which has gathered accolades through many film festivals around the world. The song “Bixa Preta” is a fucking iconic anthem for 20gayteen and for all of my maricones family out in the world fighting everyday for our existence to be respected.
We will NEVER be erased.

300+ TOP ORACLE RAC Interview Questions and Answers
ORACLE RAC Interview Questions for freshers experienced :-
1. What is cache fusion? In a RAC environment, it is the combining of data blocks, which are shipped across the interconnect from remote database caches (SGA) to the local node, in order to fulfill the reuirements for a transaction (DML, uery of Data Dictionary). 2. What is split brain? When database nodes in a cluster are unable to communicate with each other, they may continue to process and modify the data blocks independently. If the same block is modified by more than one instance, synchronization/locking of the data blocks does not take place and blocks may be overwritten by others in the cluster. This state is called split brain. 3. What is the difference between Crash recovery and Instance recovery? When an instance crashes in a single node database on startup a crash recovery takes place. In a RAC enviornment the same recovery for an instance is performed by the surviving nodes called Instance recovery. 4. What is the interconnect used for? It is a private network which is used to ship data blocks from one instance to another for cache fusion. The physical data blocks as well as data dictionary blocks are shared across this interconnect. 5. How do you determine what protocol is being used for Interconnect traffic? One of the ways is to look at the database alert log for the time period when the database was started up. Want To Get RAC Training From Experts? Enroll Now For Free Demo On Oracle RAC Training. 6. What methods are available to keep the time synchronized on all nodes in the cluster? Either the Network Time Protocol(NTP) can be configured or in 11gr2, Cluster Time Synchronization Service (CTSS) can be used. 7. What files components in RAC must reside on shared storage? Spfiles, ControlFiles, Datafiles and Redolog files should be created on shared storage. 8. Where does the Clusterware write when there is a network or Storage missed heartbeat? The network ping failure is written in $CRS_HOME/log 9. How do you find out what OCR backups are available? The ocrconfig -showbackup can be run to find out the automatic and manually run backups. 10. If your OCR is corrupted what options do have to resolve this? You can use either the logical or the physical OCR backup copy to restore the Repository.
ORACLE RAC Interview Questions 11. How do you find out what object has its blocks being shipped across the instance the most? You can use the dba_hist_seg_stats. 12. What is a VIP in RAC use for? The VIP is an alternate Virtual IP address assigned to each node in a cluster. During a node failure the VIP of the failed node moves to the surviving node and relays to the application that the node has gone down. Without VIP, the application will wait for TCP timeout and then find out that the session is no longer live due to the failure. 13. How do we know which database instances are part of a RAC cluster? You can uery the V$ACTIVE_INSTANCES view to determine the member instances of the RAC cluster. 14. What is OCLUMON used for in a cluster environment? The Cluster Health Monitor (CHM) stores operating system metrics in the CHM repository for all nodes in a RAC cluster. It stores information on CPU, memory, process, network and other OS data, This information can later be retrieved and used to troubleshoot and identify any cluster related issues. It is a default component of the 11gr2 grid install. The data is stored in the master repository and replicated to a standby repository on a different node. 15. What would be the possible performance impact in a cluster if a less powerful node (e.g. slower CPU’s) is added to the cluster? All processing will show down to the CPU speed of the slowest server. 16. What is the purpose of OLR? Oracle Local repository contains information that allows the cluster processes to be started up with the OCR being in the ASM storage ssytem. Since the ASM file system is unavailable until the Grid processes are started up a local copy of the contents of the OCR is reuired which is stored in the OLR. 17. What is the default memory allocation for ASM? In 10g the default SGA size is 1G in 11g it is set to 256M and in 12c ASM it is set back to 1G. 18. How do you backup ASM Metadata? You can use md_backup to restore the ASM diskgroup configuration in-case of ASM diskgroup storage loss. 19. What files can be stored in the ASM diskgroup? In 11g the following files can be stored in ASM diskgroups. Datafiles Redo logfiles Spfiles In 12c the files below can also new be stored in the ASM Diskgroup Password file 20. What it the ASM POWER_LIMIT? This is the parameter which controls the number of Allocation units the ASM instance will try to rebalance at any given time. In ASM versions less than 11.2.0.3 the default value is 11 however it has been changed to unlimited in later versions. 21. What is a rolling upgrade? A patch is considered a rolling if it is can be applied to the cluster binaries without having to shutting down the database in a RAC environment. All nodes in the cluster are patched in a rolling manner, one by one, with only the node which is being patched unavailable while all other instance open. 22. What are some of the RAC specific parameters? Some of the RAC parameters are: CLUSTER_DATABASE CLUSTER_DATABASE_INSTANCE INSTANCE_TYPE (RDBMS or ASM) ACTIVE_INSTANCE_COUNT UNDO_MANAGEMENT 23. What is the future of the Oracle Grid? The Grid software is becoming more and more capable of not just supporting HA for Oracle Databases but also other applications including Oracle’s applications. With 12c there are more features and functionality built-in and it is easier to deploy these pre-built solutions, available for common Oracle applications. Explore Oracle RAC Sample Resumes! Download & Edit, Get Noticed by Top Employers!Download Now! 24. What components of the Grid should I back up? The backups should include OLR, OCR and ASM Metadata. 25. Is there an easy way to verify the inventory for all remote nodes You can run the OPATCH LSINVENTORY -ALL_NODES command from a single node to look at the inventory details for all nodes in the cluster. 26. If I am using Vendor Clusterware such as Veritas, IBM, Sun or HP, do I still need Oracle Clusterware to run Oracle RAC 10g? Yes. When certified, you can use Vendor Clusterware however you must still install and use Oracle Clusterware for RAC. Best Practice is to leave Oracle Clusterware to manage RAC. For details see Metalink Note 332257.1 and for Veritas SFRAC see 397460.1. 27. Is RAC on VMWare supported? Yes. 28. What is hangcheck timer used for ? The hangcheck timer checks regularly the health of the system. If the system hangs or stop the node will be restarted automatically. There are 2 key parameters for this module: hangcheck-tick: this parameter defines the period of time between checks of system health. The default value is 60 seconds; Oracle recommends setting it to 30seconds. hangcheck-margin: this defines the maximum hang delay that should be tolerated before hangcheck-timer resets the RAC node. 29. Is the hangcheck timer still needed with Oracle RAC 10g? Yes. 30. What files can I put on Linux OCFS2? For optimal performance, you should only put the following files on Linux OCFS2: Datafiles Control Files Redo Logs Archive Logs Shared Configuration File (OCR) Voting File SPFILE 31. Is it possible to use ASM for the OCR and voting disk? No, the OCR and voting disk must be on raw or CFS (cluster file system). 32. Can I change the name of my cluster after I have created it when I am using Oracle Clusterware? No, you must properly uninstall Oracle Clusterware and then re-install. 33. What the O2CB is? The O2CB is the OCFS2 cluster stack. OCFS2 includes some services. These services must be started before using OCFS2 (mount/ format the file systems). 34. What the OCR file is used for? OCR is a file that manages the cluster and RAC configuration. 35. What the Voting Disk file is used for? The voting disk is nothing but a file that contains and manages information of all the node memberships. 36. What is the recommended method to make backups of a RAC environment? RMAN to make backups of the database, dd to backup your voting disk and hard copies of the OCR file. 37. What command would you use to check the availability of the RAC system? crs_stat -t -v (-t -v are optional) 38. What is the minimum number of instances you need to have in order to create a RAC? You can create a RAC with just one server. 39. Name two specific RAC background processes RAC processes are: LMON, LMDx, LMSn, LKCx and DIAG. 40. Can you have many database versions in the same RAC? Yes, but Clusterware version must be greater than the greater database version. 41. What was RAC previous name before it was called RAC?OPS: Oracle Parallel Server 42. What RAC component is used for communication between instances?Private Interconnect. 43. What is the difference between normal views and RAC views?A RAC view has the prefix ‘G’. For example, GV$SESSION instead of V$SESSION 44. Which command will we use to manage (stop, start) RAC services in command-line mode? srvctl 45. How many alert logs exist in a RAC environment? A- One for each instance. 46. What are Oracle Clusterware Components Voting Disk — Oracle RAC uses the voting disk to manage cluster membership by way of a health check and arbitrates cluster ownership among the instances in case of network failures. The voting disk must reside on shared disk. Oracle Cluster Registry (OCR) — Maintains cluster configuration information as well as configuration information about any cluster database within the cluster. The OCR must reside on shared disk that is accessible by all of the nodes in your cluster 47. How do you backup voting disk #dd if=voting_disk_name of=backup_file_name 48. How do I identify the voting disk location #crsctl query css votedisk 49. How do I identify the OCR file location check /var/opt/oracle/ocr.loc or /etc/ocr.loc ( depends upon platform) or #ocrcheck 50. What is SCAN? Single Client Access Name (SCAN) is s a new Oracle Real Application Clusters (RAC) 11g Release 2 feature that provides a single name for clients to access an Oracle Database running in a cluster. The benefit is clients using SCAN do not need to change if you add or remove nodes in the cluster. ORACLE RAC Questions and Answers pdf download Read the full article

Common Issues Found While Coding With CSS
Cascading Style Sheets are used along with HTML documents to describe how elements have appeared. Entire styling related tasks such as colors, appearance, font’s size, background, alignment, and spacing, etc. CSS permits great presentation of a web project. CSS interview questions act as a prime role in web development recruitments. Beginners can get a great future after referring to insights of CSS. This language contains numerous benefits. Among them, one outstanding feature of CSS is its acceptance to allow uniform modifications across different webpages. In spite of various advantages, CSS contains challenges too. The main objective of this blog is to introduce a few challenges to CSS. This might be beneficial for developing customized websites.
Let’s begin.
· In CSS, There are chances of Cross-Browser challenges because it works differently in every browser. This implies that developers are required to verify compatibility while programming execution.
· The other challenge of CSS is that it does not permit logical operations.
· CSS does not authorize web-page request and also, one cannot able to read her/his files through it
· Through CSS, one can’t able to perform Database interaction.
· CSS is less secure because of its open text-based feature. Hackers or anyone having read/write authorization can easily perform modification in CSS file and disturb the website formatting due to the lack of built-in security parameters.
· The debugging and compilation process is complex in a CSS processor.
Conclusion
CSS is a rapidly growing language to create webpages. We have discussed some of the challenges regarding the same. I hope this blog will cover gaps in CSS. If you are a beginner and don’t have much knowledge about front-end languages, you should definitely refer to the documentation or online courses to learn HTML, CSS concepts and JavaScript to build attractive web templates in minutes.

Smashing Podcast Episode 1 With Andy Clarke: What Is Art Direction?
Smashing Podcast Episode 1 With Andy Clarke: What Is Art Direction?
Drew McLellan
2019-11-05T14:30:59+02:002019-11-05T16:06:22+00:00
The new Smashing Podcast is the perfect way to take a little bit of Smashing along with you on your morning commute, when working out at the gym, or just washing the dishes. We’ll be bringing you a new interview with a Smashing expert every two weeks, directly to your podcast player of choice. You can subscribe in your favorite app to get new episodes as soon as they’re ready, or just listen using the player below.
To get things off with a bang, we’re launching the first two episodes today. Each episode will be accompanied by a post (just like this one) with a full transcription of the interview here on Smashing Magazine.
In this inaugural episode, Drew McLellan talks to designer, author, and speaker Andy Clarke about Art Direction. What is it, and how can it be applied to our web design projects? We dig into the topic and see if we can get to the bottom of things.
Show Notes
We discuss Art Direction for the Web, a new book by Andy Clarke.
Andy’s Inspired Design Decisions series of articles can be found on Smashing Magazine, and are available first with your Smashing Membership.
We found some examples of the art direction involved in the Boddingtons Cream of Manchester campaign discussed in the episode.
You can follow Andy on Twitter where he is @Malarky or via his website Stuff & Nonsense.
Transcript
Drew: He’s a well known designer, public speaker and author of numerous influential web design articles and books and has recently released his new book, Art Direction for the Web, with Smashing Magazine. Along with his wife, Sue, he founded and runs a web design studio, Stuff and Nonsense, in North Wales where he consults with companies big and small all around the world. You may know of his passion for gorillas but did you know that as a school child he was Junior National Bassoon Champion for three years in a row. My Smashing friends, it’s Andy Clarke. Andy, how are you today?
Andy Clarke: Eee, I’m smashing, lad.
Drew: So, as I mentioned your new book, Art Direction for the Web, is now available but obviously this isn’t your first book. Hard Boiled Web Design, that I’m sure people will know, and way back in the day, Transcending CSS. When did the idea for this particular book come about?
Andy Clarke: This was an interesting one because, like you say, this is number four in terms of books. Sue had always said that she’d hunt down and kill anybody that asked me to write another one because I am such a bastard when I’m writing books. I’m just not a nice person to be around and so I kind of didn’t ever want to do another, kind of, major book after Hard Boiled. So my original plan was actually to write three little, we called them shots in the whole, kind of Hard Boiled theme. Three kind of little 80 to 100 page, little shots. In the kind of the style of, or the length of, A Book Apart type length. Art Direction was going to be the first one and when I started to get into it which was way back at the beginning of, I think it the beginning of 2018 when I started it.
Andy Clarke: The more and more I kind of got into it, the more I realized that this, there was no way this was going to be a short book. All the things I wanted to talk about were just never going to fit. So I kind of threw the whole three shots idea out of the window and we just concentrated on doing this one. So I suppose the idea for this one came actually quite a few years ago even before a lot of the stuff that I talk about in the book in terms of what we can do with design and what we can do with CSS and all that kind of stuff was even a possibility. But it’s been a long time coming this one, I think it’s the kind of spiritual successor to some of the other stuff that I’ve done in the past. That sounds a bit grandiose, doesn’t it?
Drew: No, not at all. I mean, like many people, I’ve come into this field of building stuff for the web without any real formal background in, well, I’m a developer. I don’t really have a formal background in programming. I’ve just sort of picked it up as I go along and I certainly don’t have a formal background in anything to do with design. I’m not really familiar with the terminology and the concepts and the, a formal training would instill, particularly in design. So for people like me, when we talk about art direction, what exactly is art direction?
Andy Clarke: That’s an almost impossible question to answer because it means so many kind of different things at different levels. But I’m going to give an example. Do you remember back in, I mean we’re talking 15-odd years ago now but do you remember the adverts? In fact, for the show notes I’ll send you some links. But do you remember, there was an ad campaign called “The Cream of Manchester” for Boddingtons Beer. One of the things that they did, there was some really funny TV commercials but one of the things that they did incredibly successfully was a whole series of graphics which went on posters and various other things which were a glass of Boddingtons beer with the incredibly creamy head, which was the most important part of Boddingtons Beer and they shaped the head into all kinds of different things. So it looked like an ice cream and it looked like a quiff and it looked like all kinds of stuff. And what that did was it told the story of what was important about Boddingtons Beer through the medium of design. So it didn’t necessarily just say Boddingtons has a very creamy head. What it did was it showed you that through the visuals but then with the, in combination with the words, you got this very, very clever idea about what Boddingtons Beer was all about. And that, in one level, is art direction.
Andy Clarke: Let me give you another example. I can’t remember which magazine it was, now it might have been Rolling Stone. I can’t remember exactly which magazine cover it was now but a couple of years ago there was a very famous magazine cover and it was a picture of Donald Trump and they’d taken the barcode which normally sits in the bottom left or bottom right hand corner of the cover of the magazine and they’d put it on his top lip and made him look like Hitler. That’s art direction. That’s using design to convey a message to tell a story, to communicate something to an audience but through design.
Andy Clarke: And when we think about applying those things to the web, it is exactly the same kind of purpose but what we’re doing is we’re using all of those aspects of design. We’re using a layout. We’re using typography. We’re using color choices. We’re using all of these kind of design ingredients to do whatever it is that we’re trying to do online. So we might be telling a story of…a story through an editorial magazine or a news story or we might be telling a story about why you should buy my brand of power drill rather than somebody else’s brand of power drill. And it extends even into user experience because we’re really thinking about what is somebody feeling at this point? How do we communicate with them? How do we try and cheer them up, try and cool down. Do we want to be kind of quirky and delightful or do we want to be sort of more serious and conservative. And all of those aspects of evoking an emotional response in somebody is art direction.
Drew: Like accessibility, we often say that that really is the responsibility of everyone in the team but then in practice there tends to be an accessibility expert who really knows their stuff and can sort of help everyone review their work and push things forward. Is it the same with art direction? Is it something that everybody in a team should be looking at? Or is it something you hire in a big bright art director like yourself to come in and tell everyone what they should be doing?
Andy Clarke: No, it is exactly the sort of thing that everybody should be paying attention to. Every decision that we make in terms of design is an opportunity to tell a story. And that can be a big story or it can be a tiny story. And even things, for example, the style and the wording of microcopy can help to tell the story. Now, what we really need is not just everybody kind of paying attention to what that message is but we also need to know what the message is to begin with.
Andy Clarke: And one of the things that I think has been lacking over the last however many years when we’ve been kind of evolving the web as a medium is we’ve kind of moved away from this idea of the web as either a kind of creative medium or as a great medium for storytelling. And that’s the kind of thing if you go to an ad agency, then you’re not going to walk far through the door before you fall over an art director. But that’s not something that you generally find, it’s not a job title that tends to happen at digital agencies. It’s just, you’ll find UX people and project managers and developers and all manner of different, in parentheses, product designers. But the overall thinking about what message are we trying to convey, how do we implement that through design? But then there’s that kind of, what you would think of as creative direction but it is slightly different. Where somebody is basically just checking that everything is on brand, is on message, is part of telling that story.
Drew: As a developer, if I want to start getting involved in the art direction of my projects, where on earth do I start? Is this something that I can learn or do you have to be born this way?
Andy Clarke: I can’t think about the way you were born. You’ve landed on your head. No, it is something that can be taught and it is something which takes practice. So you don’t need to have gone to art school or studied advertising or whatever. I never did. I didn’t even do a graphic design degree back in the ‘80s. I was a failed painter. But it’s the kind of thing where, I think it’s a change of kind of, mindset a little bit. In thinking about, it’s not just about the practical aspects of designing a website but it’s also the thinking about, “Well, what are we trying to do?”
Andy Clarke: So let me give you an example, right. So Smashing Magazine, I did some early conceptual work with them for the redesign that we see right now. And the way that we did that was to basically just host a bunch of workshops where we all got together and we sat around a big table for a week and we did this kind of three or four times where really what we were trying to do was to get to the bottom of what the Smashing message was. And how Smashing wanted to be perceived and that was basically a great big roundtable exercise which was basically designed to just get the Smashing guys, Vitaly and Markus and others, thinking about what the real purpose of Smashing was and how they were going use design to communicate the unique kind of personality and attributes of Smashing.
Andy Clarke: And to help that along, we did a load of, kind of early rough design stuff. And then from what they learnt, they then turned to Dan Mall and said, “Right, we’ve got these words, we’ve got these, call them design principles if you like, that we want to then pull out through the design. We want to be bright and bold. We want the experience turned up to eleven. We want to be quirky” and all these kind of words that had come out of our early design discussions. And then he would then produce designs that sort of fitted with that brief.
Andy Clarke: And the interesting thing about that if we relate this back to your question where you’re saying “Where do I get involved?”, it’s, is, if we were kicking off a project for Notist, for example. The very obvious thing is that it does some things. It hosts your slide decks. It adds your speaker profile or whatever but those are just, they’re the things that it does. But your aspirations for that product are much, much more than just the bunch of practical things that it does. So from a brand and from an art direction point of view, yes, you want to be designing a product which is streamlined and simple to use and reliable and all of the stuff that it, kind of goes with it. But there’s a bigger picture and I would be speaking to you about what that purpose really is. Is it to inspire other speakers to get onstage? Is it to share information more widely? Is it to make talks that happen at remote conferences much, much more visible to people wherever they are in the world. There’s obviously a bigger thing going on in here.
Andy Clarke: And then once we’ve kind of understood what those real, kind of, what our real purpose was, then we can think about how do we convey that message through the design. And that’s where a designer would come in with a creative brief and then we would look at, well, what typography style is going to convey that message? What kind of layout? What kind of color scheme? What kind of graphics are going to really tell that story because you can easily just say the world’s most popular slide deck sharing site as, what’s that nasty one? Not Speaker Deck, the other one. SlideShare. Dreadful, absolutely dreadful. What we would look to do is something like Notist if we consider an art direction point of view is to consider, how do you want people to feel when you’re using the product and how do you want them to feel when they’re making the decision to choose your product over somebody else’s. And that’s essentially what it boils down to.
Drew: So it’s very much about how the brand, in a sense, is embodied in every little detail and every part of the design, both the sort of visual design and the functional design. Would that be accurate to say?
Andy Clarke: Yeah. Yeah, absolutely, and that should be the case with anything that we’re making. It’s why I get so disappointed when I see stuff which is not a gajillion miles away from framework default in terms of layout or button styles or type hierarchy or whatever it happens to be, all of these kind of design things. Because, to me that’s like completely missing the point of the design. Yeah, it might be a functional thing to use but does that make it nice?
Drew: So obviously modern websites are mostly spat out of a CMS into identical templates. So if kind of one of the jobs of art direction is to invoke this sort of emotional response to something on a page, can that be done through spitting out content into templates or can it be done by machine?
Andy Clarke: Well, if I had the solution to that problem, I’d be a very rich man because it is actually the problem that a massive amount of the web is struggling with. Whether it would be news outlets or magazine outlets or editorial or whatever. And it’s a question which comes up again and again and again. And actually the people that have really solved this problem best of all that I took to my knowledge it ProPublica who I talk quite a lot about in the book. And our old friend Rob Weychert basically designed the CMS implementation for ProPublica. And the way that they did it was that they said, “Right, okay, these are our foundations style, this is what the ProPublica website looks like and an article on that website looks like if I do nothing. This is what it is.” But obviously they want to be able to customize that in all kind of different ways whether it would be type or layout or color theme or anything else. What they did was very simply they just had a field in the CMS that they could inject custom CSS. And because they understood the cascade and they understood how CSS builds they would only then be able to overwrite certain things.
Andy Clarke: Now, not everybody’s going to want to go to the extent of custom designing articles in the way that ProPublica do. And they don’t art direct or over design everything. It is only these really kind of special pieces that they tend to do a really great art direction job on. But there are ways in which we can do this. One of the great, we always talk about separation of, or we used to talk about, it used to be the thing where we would separate content and structure and style and behavior. Now it seems like everybody piles everything into JavaScript but moving swiftly on. One of the things that you can do, is you can separate out the CSS logic. And as long as you don’t bake in the style of the page into the HTML, as long as you keep things flexible, you can then do an enormous amount, particularly when we’ve got things like CSS grid, flex box, which are kind of, almost like content independent in a way, and CSS variables.
Andy Clarke: So I’m working on site with a French football magazine which will hopefully be finished by the time this podcast goes out and that’s a question that we’re trying to solve right now. So what I’ve done over the last couple of weeks is I’ve designed probably about half a dozen different layout templates. Now, some pages are fixed. They’re never going to change, they’re never going to be wildly different. If you think about something like a league table or a list of results from a football Saturday then you’re not going to do an enormous amount with it. But when it comes to things like player profiles and team profiles and some of the more, kind of, involved content, what I’ve done is I’ve designed about half a dozen different layout combinations. All based on exactly the same CSS. And what I’m doing is I’m then extracting out certain things that, for want of a better word I’m calling themes. Just in terms of right, in this design, Design A, and I give them all names. I give, I’ve given the theme, I’ve named them after French football players. So if you want to, if you look at the Cantona design or Cantona theme, what do the headlines look like? What do the block quotes look like? What do the table headers look like? What do the buttons look like? There’s a specific style that goes into that theme which is independent of the layouts.
Andy Clarke: And the other thing which is independent of that theme is the six different color schemes that I’ve come up with. So basically by the end of the project, you’ll have a color layer, a theme layer and a layout layer that they are able then to kind of pick and choose. And that can be automated, it can be turned into toggle switches in the CMS or whatever it might happen to be. So there are ways of doing that.
Andy Clarke: Now that’s not a particularly kind of appropriate thing for, in terms of pure art direction but the same mechanics can then be used if we want to be saying right, “Well, we do want to customize this so let’s introduce these new fields.”
Drew: One of the examples in the book, quite early on of a, sort of art directed site is the UK government’s gov.uk site, which is excellent as a user of it. It’s a site I really enjoy using it but it’s not one that I would immediately think of as being art directed, in inverted commas. It’s not very visually rich. It’s quite sparse and not sparse in a minimalist way but sparse in a utilitarian way. Art direction doesn’t need to be flashy, I’m taking from that?
Andy Clarke: Well, I have spent years joking about gov.uk and I’ve always thought of gov.uk as being the website that design forgot. I’ve often said gov.uk, not known for its creative flair. And it was interesting, when I was doing a series of podcast interviews for the book, I was talking to Mark Porter, who used to be creative director at the Guardian. You can’t read a book about editorial design without Mark cropping up at some point. In fact, he’d be a great person for you to speak to on this podcast at some point to get a different perspective. And I was saying to Mark in our conversation, “Look, I can remember great art directed ad campaigns on TV, in magazines. We’ve talked about art direction in newspapers and print publications, etcetera, give me an example of what you think is great art direction on the web.” And I was absolutely stunned when Mark said, “Gov.uk.”
Andy Clarke: And it took a while to sink in but actually he was absolutely right because if art direction is about making people feel in a certain way then gov.uk does its job incredibly well. It doesn’t need to be flashy. It doesn’t need to be overly designed. It doesn’t need to push boundaries or do any of these things that you might associate with newfangled CSS grid webby stuff because it does what it does and it’s, the design is absolutely appropriate to, not only to the audience and what they want to do but also how gov.uk want people to feel when they’ve left the site. When you’ve gone on there and paid your car tax or looked up when your bin collection’s going to be or whether it’s safe to travel to Cameroon or…I leave that site reassured that I’ve been given the information that I was looking for in a thorough and professional way. I don’t think to myself, “Oh, is that site trustworthy?” And not just because its gov.uk but because the whole experience has just been designed to leave no unanswered questions in my brain.
Drew: Yes, it’s so, sort of simple. It gives you real confidence in the information you’ve found is correct or the process that you followed, there’s a very clear way through it so you feel like, “Yes, I’ve completed that successfully because it was unambiguous.”
Andy Clarke: Now, would I design certain things differently? You can bet your bottom dollar I would but would I want to think about improving typography? Yes. Would I want to get more granular in terms of typographic design so that we can improve the way that numerals look or dates look or tables of data look or whatever? Yes, absolutely there’s some things that I would look at there and say, “I want to improve the design of that aspect of gov.uk.” But in terms of the art direction, no, everything that they, that you see whether it’s intention or not in terms of, I don’t know whether there is an art director at gov.uk, but everything that you see just contributes to how people feel at the end of the experience and that’s good art direction.
Drew: The book itself is really beautiful. I’d seen the ebook version of it early on which is absolutely terrific and I recommend that. But then I had the pleasure of picking up an actual printed version and I really recommend the printed version even more. It’s, every sort of spread is as you’d expect, sort of custom designed and it’s just jampacked with loads of inspirational examples. And it’s so heavily illustrated, I mean there’s hardly a double page spread that’s all text. It’s all illustrated with stuff. It’s really great. To be honest, it’s not the sort of book, not knowing anything about art direction before our conversation, and before looking at, actually looking at the book. It’s something I wouldn’t have picked up thinking it was for me but once I started looking through it, I thought, “Yeah, this is really good.” Obviously, you’ve designed it, you’ve designed every spread by hand. What was that process like?
Andy Clarke: It was a lot of work. I mean, first of all, I just want to say an enormous thank you to my son, Alex, who actually typeset that entire book from start to finish. What we wanted to do when we set out to produce the book was to show off some inspiring stuff but we also wanted it to be incredibly relevant to people at various different stages or different areas or whatever. And Sue would be quite, sort of brutal with me and say, “Don’t forget to explain it this way. If somebody’s using Squarespace or Shopify or Bootstrap Grid or whatever, then you need to talk to those people as well.” So what I did was, I actually spent about three months designing a whole ton of different examples. And me being me, I had to kind of, everything had to be perfect. There had to be a theme so I kind of came up with this hard boiled based London gangster theme for an app and a website that kind of goes with it. And then everything kind of just spread on from there. What was interesting in terms of the actual design of all those examples was what you learn how to design in one part of the book you then learn how to build in another part of the book. So there is this kind of balance to it.
Andy Clarke: But then, so basically what would happen is, was that I came up with about half a dozen different layout scamps for the main body of the book. I was much, much more detailed on the, sort of the examples I didn’t design, some of the other examples from elsewhere on the web. But the general body of the book, I just did half a dozen, kind of just very simple box layout sketches. Alex would then interpret that and chapter by chapter we would then go through it. So literally every single page has been tweaked. And I haven’t done, I’ve never done a book that’s got, had that much attention to detail.
Drew: Yeah, it really shows and the end result is fantastic and I’ve been learning a lot from it. So something I always like to ask people. I’ve been learning about art direction, what have you been learning about lately? Is there anything in particular in your work and your projects that you’ve been learning and swatting up on?
Andy Clarke: Yeah. I’ve been really trying to get to grips with more advanced grid stuff. That’s something which I’ve been really trying to sort of push the boundaries of. And along with this kind of, because I’ve been experimenting with, “Here’s a great, here’s a quirky layout. How would we build that?” And along the way comes things like SVGs and making SVGs responsive and I actually learnt today that you can’t use the picture element with inline SVG. You have to use an IMG element if you want to swap one picture for another or one source for another in HTML. So my main, I’ve actually been going back to really just learn a hell of a lot more about code. I think that quite, you go through phases where there’s a huge amount to learn or it seems that way and there’s something new that you want to get to grips with. And then things kind of plateau out and you churn through the same stuff or you use the same patterns or the same kind of methodology for awhile and then there’s another spike. And I’m kind of in one of those spikes at the moment.
Drew: Obviously the book is available now. You’ve also been writing a series of articles for Smashing Magazine around some of the same sort of ideas, picking out some bits and bobs which we’ll link to in the show notes. But you’re also doing a webinar series, is that right?
Andy Clarke: Yeah, well, the articles in the webinar is all the same stuff so I called it Inspired Design Decisions. And it came about because I was actually in Magma Book Shop, which is a brilliant magazine book shop in London, before Christmas. I was with our friend, Al Power, and we were kind of thumbing through magazines and I was geeking out and going, “Oh, look at this beautiful quote. That layout looks amazing. Coo, I love the way that they’ve tied this image with the color of the text and blah, blah, blah.” And Al said, “Well, I’ve never really thought a bit like that. I’ve never really thought about lessons that we can learn from editorial design or magazine design or other things. And you just talk about it in ways that just make sense. You ought to write about this stuff.” So I don’t want to write another book at the moment because well, Sue would hunt down and kill anybody that asked me to. So the idea came about was, well, why not do a series of articles over the course of the year where I would touch on a particular topic and a particular piece of inspiration.
Andy Clarke: There’s three gone out now, so far. There’ll be four, maybe five by the time this podcast goes out. Each one is the webinar content with Q&A. Everybody that is a Smashing member also gets access to a really, really nicely designed PDF version of all of the articles and all the code that goes with it. And then what we do a month later is we’ll put that article out for free on the public Smashing Magazine website. And what we’ll do sometime next May, is we’ll collect all of those twelve articles together and we’ll re-edit them and get the continuity right and that’ll be another book that comes out, probably next April, May time.
Drew: That sounds great.
Andy Clarke: It’s a lot of fun.
Drew: If you, dear listener, would like to hear more from Andy, you can follow him on Twitter where he is @Malarkey and find examples of his work and hire him via his website, stuffandnonsense.co.uk. Art Direction for the Web is available now through Smashing at smashingmagazine.com/books and I commend it to you. Andy, do you have any parting words?
Andy Clarke: (Beep) to Brexit.

💡 Tip of the Week
supported by
Defining quotation styles with the <q> tag
When styling your site you may be happy with the "default, straight quotation style", but if you're keen on getting your typography just right then there is a way to ensure your quotation marks are “smart” via CSS.
As explained here, the HTML <q> element signals that the contained text is a short inline quotation. Most browsers implement this by surrounding the text in "quotation marks". You can, however, add a style to modify what automatically appears around the text:
q { quotes: "“" "”"; }
It may be hard to make out in email, but this rule will wrap your inline quote with alternative 'smart' quotation marks. This blog post expands on how this simple tip can be used for multilingual sites, such as using differing quotation rules for different languages (like German).
Another idea is outlined in this recent blog post from Michael Lazarski, who shows how this technique can even be used with emoji for an 🙌 altogether different 🙌 approach.
This Tip of the Week is sponsored by Flatiron School, where you can learn software engineering, data science, or UX/UI design in just 15 weeks online or on campus.

CSS-Tricks Chronicle XXXVIII
Hey hey, these “chronicle” posts are little roundups of news that I haven’t gotten a chance to link up yet. They are often things that I’ve done off-site, like be a guest on a podcast or online conference. Or it’s news from other projects I work on. Or some other thing I’ve been meaning to shout out. Stuff like that! Enjoy the links!
I chatted with Paul Campbell the other day during Admission Online, an online conference put together by the Tito crew . They’ve published all the videos there including mine.
I had a chance to chat with Paul about his Tito service about last year on ShopTalk in a really great episode. Tito is a best-in-class software tool for running a conference. It helps you build a site, sell tickets, manage attendees, run reports, and all that. Clearly the COVID-19 situation has impacted that business a lot, so I admire the accelerated pivot they are doing by creating Vito, a new platform for running online conferences, and running these conferences super quickly as a way to showcase it. If you’re running an online conference, I’d get on that invite list ASAP.
Jina Anne has been doing something new as well in the online event space. She’s been doing these 30-minute AMA (Ask Me Anything) sessions with interesting folks (excluding me). Upcoming events are here. They are five bucks, and that gets you live access and the ability to actually ask a question. Jina publishes past events to YouTube. Here’s one with me:
youtube
I was interviewed on Balance the Grid. Here’s one exchange:
What do you think are some of the best habits or routines that you’ve developed over the years to help you achieve success in your life? I’m quite sure I have more bad habits than good, so take all this with a bucket of salt. But one thing I like to do is to try to make as much of the time I spend working is spent working on something of lasting value.
That’s why I like to blog, for example. If I finish a blog post, that’s going to be published at a URL and that URL is going to get some traffic now, and at least a little bit of traffic forever. The more I do that the more I build out my base of lasting content that will serve me forever.
Over at CodePen, we’ve been busier than ever working toward our grand vision of what CodePen can become. We have a ton of focus on things lately, despite this terrible pandemic. It’s nice to be able to stay heads down into work you find important and meaningful in the best of times, and if that can be a mental escape as well, well, I’ll take it.
We’ve been building more community-showcasing features. On our Following page there are no less than three new features: (1) A “Recent” feed¹, (2) a “Top” feed, and (3) Follow suggestions. The Following page should be about 20× more interesting by my calculation! For example, the recent feed is the activity of all the people you follow, surfacing things you likely won’t want to miss.
You can toggle that feed from “Recent” over to “Top.” While that seems like a minor change, it’s actually an entirely different feed that we create that is like a ranked popularity feed, only scoped to people you follow.
Below that is a list of other recommended CodePen folks to follow that’s created just for you. I can testify that CodePen is a lot more fun when you follow people that create things you like, and that’s a fact we’re going to keep making more and more true.
We’re always pushing out little stuff, but while I’m focusing on big new things, the biggest is the fact that we’ve taken some steps toward “Custom Editors.” That is, Pen Editors that can do things that our normal Pen Editor can’t do. We’ve released two: Flutter and Vue Single File Components.
The word “feed” is new. We don’t actually use that term on the site. It’s a word we use internally on the team and what’s used by the technology we’re using. But I think it’s a good general description for the CodePen community as well, since CodePen is a developer-facing site anyway. I suppose “stream” is also a good descriptor (and just so happens to be the literal name of the tech we’re using.
This is about the time of year I would normally be telling you about the Smashing Conference I went to and the wonderful time I had there, but those in-person conferences have, of course, been re-scheduled for later in the year. At the moment, I’m still planning on Austin in October and San Francisco in November, but of course, nobody knows what the world will be like then. One thing is for sure though: online workshops. Smashing has been doing lots of these, and many of them are super deep courses that take place over several weeks.
Lots of conferences are going online and that’s kinda cool to see. It widens the possibility that anyone in the world can join, which is the web at its best. Conferences like All Day Hey are coming up in a few weeks (and is only a handful of bucks). Jamstack Conf is going virtual in May. My closest-to-home conference this year, CascadiaJS, is going virtual in September.
I got to be on the podcast Coding Zeal. I can’t figure out how to embed a BuzzSprout episode, so here’s a link.

Smashing TV has been working with our friends over at Mozilla to bring you content from their upcoming View Source conference in Amsterdam. We’re really excited about the event that they are putting together.
Here on Smashing Magazine, we often feature articles that explain a little bit about how web technologies are created. I’m a CSS Working Group member, and I enjoy sharing the things that we’ve been discussing in our meetings, such as my post on “Designing An Aspect Ratio Unit For CSS”. Earlier this year, we published an article by Amy Dickens, “Web Standards: The What, The Why, And The How” in which Amy explained what we mean by web standards and how standards groups work. We’ve also shared with you how browser vendors such as Mozilla are making web platform features easier for us to use in our work, such as this post by Chen Hui Jing, “Debugging CSS Grid Layouts With Firefox Grid Inspector”.
If you enjoy articles like these, then you will love View Source, and the chance to spend two days with people who are involved with specifying the web, and implementing it in our browsers. It’s a very special View Source because friends from Google, Microsoft, Samsung, and the W3C are joining Mozilla to bring the best of the web to developers and designers this year. I’ll be there too, wearing my CSS Working Group hat, as part of a discussion corner on how CSS gets into browsers.
Our own Vitaly Friedman has been interviewing some of the speakers from the upcoming event, and you can watch the first of those interviews now.
Enjoy this conversation with Kenji Baheux, a Product Manager at Google, working on Chrome/Web Platform, about the web in different parts of the world, differences between usage of the web, and what we need to be aware of when expanding to an unfamiliar market in India or Southeast Asia.
Mozilla’s View Source Amsterdam event is happening on Monday and Tuesday, Sept 30th and October 1st at Theater Amsterdam. Get your tickets here. You can save 25% with the code Smashing_VS, or use a direct link to check out. I look forward to meeting you there!
An Interview With Kenji Baheux
Vitaly: Hello and welcome to one of those interviews on view source speakers, live sessions with a few behind-the-scenes about the speakers and the sessions and the talks and the interesting topics. And I’m very happy and honored to have Kenji Baheux with us today, from Google, currently living in Tokyo, Japan. How’re you doing today, Kenji?
Kenji Baheux: I’m doing pretty good, thank you.
Vitaly: Fantastic. I have questions. You know, I always do, I have too many questions I believe, but I’m really curious because you know, I know that you’ve spent quite a bit of time and you know, the session you’re going to present today, you’re going to present that in view source which is all about multicultural web thing, right? It’s like the web beyond the scope of what we’re used to, and very often when we think about designing a building for the web, we’re thinking about designing and building for our web. You know, for wonderful screens and wonderful devices and wonderful connections and powerful devices, and all of that. But when we think about designing for Indonesia, when you think about designing for Southeast Asia or India or kind of all places where we’re are not familiar with, we have stereotypes, right? We tend to believe slow devices, unreliable connections, bad screens, you know, horrible, horrible conditions. Almost the opposite of what we’re used to, is it the true web outside of the comfortable bubble that we live in? Tell us.
Kenji Baheux: So, unfortunately, there is some truth to that, and the interesting thing is that the market in India and Indonesia they have like a common aspect, but there are differences — especially around connectivity, for instance. It used to be the case that connectivity in India was very expensive, and so people like wanted to save like data and so they, you know, they didn’t want to use the web too much. For instance, today, it has become a lot more affordable and so people are not concerned too much about data consumption. It is still true that maybe in the newer kind of like user segment, it might still be quite expensive, but it’s getting better quite fast. So I think like in term of like data usage, it’s not so much a concern anymore, but at the same time like 4G is available over there, but if you look at the speed and the like readability of the collection, it’s more kind of like a 3G connection than a 4G connection.
Kenji Baheux: And so you need to be careful about like your assumption about, “Oh, 4G is affordable and therefore the connectivity is going to be the same than what I experience in my own country.” Like there are some stats but like, for instance, I think India is actually at the bottom in terms of speed for 4G and it’s about a 10x slower than what it should be compared to like the top one, for instance. So there is some nuance there and also because there are a lot of users in India depending on the time of the day, the speed will like fluctuate and also sometimes like depending on the bandwidth the [inaudible] will keep up.
Kenji Baheux: And so you might lose connection. You might be on the go. There are a lot of dot points, like not enough antennas and things like that. So you need to be careful about speed and also like this idea that not always on connectivity is not always what user experience is over there. And if you contrast that with Indonesia, Indonesia is doing a bit better in terms of speed, like 4G over there is more kind of like 4G, and there are some reasons to that. The country is much smaller, urbanization is much higher, and so it does help, right? The user, they can reach out in Indonesia tend to have better infrastructure. So that’s one aspect. You mentioned also the devices, so on that, like it’s still very true that the devices tend to be on the lower end of the spectrum. And so like iPhone for instance, are a very tiny market share mostly because those devices are too expensive. And so most of the people can’t afford like high-premium devices.
Kenji Baheux: It used to be the case also that the memory that devices have was very low and this has become better, but it doesn’t mean that the device is cracked, right. I think the OEMs understood what the user cares about. Like does it have a great camera, does it have enough RAM, what about the storage? But then they want to keep the price low and so they are going to find ways to make the device cheap, right? And so it means like slow CPU, slow storage, and things like that. So you need to be careful about the connectivity, but also how much JavaScript you send because it’s going to make your page go slow, right?
Vitaly: It’s, you know, you spend quite a bit of time thinking about performance and also now because you’re working at the Chrome team and you kind of want to work on the instant loading team — if I’m correct, right? It means for me, personally, it means that you have very different challenges at times as well because probably now living in Japan or living in Indonesia kind of have to really look into the types of devices people are using, the habits that they have, the cultural ways of how the web is different. You know, if you look into Africa, for example, I’m sure as you probably know, of course, many people that Africa will be using kind of totally bypassing credit cards altogether, sending money by SMS and having a different kind of web applications, right? So that makes me think as well, when it comes to performance, obviously we want to make things fast and all that, would you say that progressive web apps as a model has become or is becoming more and more established just because it’s kind of an easier way in to get to better performance in India, in Southeast Asian, and so on?
Kenji Baheux: Yeah, we’ve seen a trend of success with PWA in those markets, for the reasons that I’ve outlined, right? If you build a PWA right, it’s going to minimize the amount of data that you fetch, right? You can use the storage and API to make sure that you don’t over-fetch. You can also deliver a very fast-like experience by showing at least a bit of like a piece of UX and then fetching the new content, right? You can minimize the amount of content you need to fetch in order to show the letters like data. So it’s, I think it’s a great fit. It does help a lot of like partners over there.
Vitaly: Many companies that they kind of work with and some of my colleagues are working with, they have a very difficult time moving kind of exploring new markets, moving their architecture, their application, the the way they built up their app or the website really on these markets kind of trying to gather that market share. And it’s very often not very clear why is that? Is it just because the architecture that we’re used to with this mountain of JavaScript that we are pushing with, you know, the Western World that say it’s just totally unacceptable for Southeast Asia? And again, I don’t know, China’s a difficult story anyway, and India. So in many ways, many of these companies see as one of the paths to get to those markets is just built something entirely different. So when you see, if you see, let’s say somebody who had maybe watching this session later trying to get through those markets, would you recommend to adapt the existing architecture, try to kind of make it work for those markets, or would you say it’s better to start from scratch and use something like an assistant ecosystem that’s already there?
Kenji Baheux: Yeah, I think it’s usually better to start from scratch because you might be tempted to try to keep around different features because maybe you’ve seen them doing well in your market and so you, you think those will be like super important to have. And so it’s going to be hard to make some trade off. And so it might be better to start from scratch and like really find, okay, what are the keys— what is the goal of this product? What are we trying to achieve? And keep it to the essential and start from there and see if you really like your product too, it’s bare minimum, like how fast can it float on the connectivity that you can find in markets like that? Like, try to get a low-end device, it’s not too hard to get something that could feel relevant for the market that you are trying to target and just play with it.
Kenji Baheux: I think trying to create a product on your desktop computer or even looking at it like on an iPhone or like a high-end Android device is not going to give you a good idea of like what your experience is going to be. And so you need to really like put yourself in the the shoes of your customers and really like confirm for yourself that what you have is going to work. So yeah, start from something very simple like the bare minimum that your product is about, and see how far you can take it from there.
Vitaly:It’s interesting to also be talking about people, but also… most of the time when we have these conversations about performance, we think about devices. You know, when you start thinking about internationalization and localization and all those things that are actually just going to those markets, I start wondering about the habits of people. Maybe they use the web very differently. So this is exactly what you’re saying, right? We need to do some research to understand how people are used to certain things. What would work? Maybe a feature you spent two years on here in Germany somewhere is just not going to work at all in India, right? So because, I mean, I just have to ask you because I’m so curious, it’s maybe not on the technical side, but I’m just curious. So if you compare the web, how people use the web, but say in the Western World, and again, let’s say in Japan where you spent the last 20 years, I believe, how is it different? I mean, I’m sure that there are certain things that are just, just totally confusing for somebody who experiences, let’s say, the way people are using the web in Japan coming from very different culture, did you have any kind of cultural shocks or anything of that kind or do you see things differently?
Kenji Baheux: That’s an interesting one. I think one of the most surprising thing for me when I arrived in Japan, like 20 years ago, was the fact that the website were like very visual, to the point of like being very noisy. Like from a European viewpoint, it’s kind of like, oh, this is way too much in your face. Like, there was so much going on on that page, how can you even understand how to use it? But actually this is what like most users are actually here, like when it comes to user experience, they want to know more upfront about the product, and so you end up with this like long page detailing all the things about why this project is like the most amazing thing in the world. And then at the bottom of it, there is like finally a way to purchase that product, so that’s one typical user experience that I’ve seen a couple of times already.
Kenji Baheux: So yeah, so that’s very visual: Trying to put as much information upfront about what the product is about. So that’s for Japan. And then for countries like Indonesia and India, especially in India, there are a lot of difficulties around language. As you probably know, India has a lot of official languages and so you really need to understand which users you are trying to reach. Because if you don’t have the content in their language, it’s going to be very hard for them to understand how to use the website, and so on. For most, it’s the first time that they are getting online and there are still a lot like new users getting online every day, and so they don’t have any like notion of like what a tab is like background tab, all of these things that we take for granted, like a lot of users actually that’s the first time that they are online, and so it’s very hard for them to just know about the things we take for granted. And so be very careful about making sure that your product is like self-explaining, and that there is nothing that people need to know in advance, for instance.
Vitaly: I’m also wondering, very often when we’re building products or when we’re designing products, we tend to think that we are building this technology that’s almost neutral, but in the end, whenever we’re building something, we always reflect our identity somehow in the little snippets of JavaScript and CSS we’re writing, and so I think that, in many ways, as designers and developers, we also have certain stereotypes when it comes to designing for those markets or kind of adapting for those markets. So what do you see, I mean, I mentioned one of them in the very beginning, like everything is slow, everything is horrible, totally unreliable and all of that — what do you see maybe as other common misconceptions or myths surrounding global web from people who are designing and building in a Western World Web?
Kenji Baheux: Yeah, that’s an interesting one. I think one particular aspect is the local players tend to be much more successful for various reasons, but one of them is that, especially in Indonesia, they know that the population is very young in general, and so they opt for a more casual tone which is something that I guess most websites in the US and EU don’t tend to do a lot. And so if you’re in e-commerce, you might be tempted to be very serious because you want to present yourself as the company that people can trust, but it might actually be the [inaudible] to your brand image if you go to a market like Indonesia where people want to have a more fun experience maybe.
Vitaly: Right, and also if you look forward into how things are evolving or how they’ve changed, I mean, you’ve seen tremendous change on the web over the last 20 years, I’m sure, but I’m wondering also when we look forward, let’s say five years from now, and look into connectivity, it seems like there is this gap that we used to have. It’s kind of bridging, we have pretty much stable connectivity that’s coming, at least worldwide, it’s still a long way to go, but it’s, you know, it’s coming. How do you see the web — the World Wide Web as we intended it to be from the very first place — evolving? Will we breach all these gaps between the Western world and non-Western world, at least in terms of the web? Or are there going to be significant cultural differences still?
Kenji Baheux: Obviously, eventually, things will get in a similar place in terms of conductivity and, like, maybe even like devices. But I think it’s going to take a while because as I said, there is still a lot of like new users getting online for the first time, and for them it’s like the price of data and devices are getting in the affordable realm, and you see, especially in markets like India for instance, there is still a lot of like feature phone and it’s not the like the old-side feature phone. It’s kind of like a more fully-fledged feature phone. I believe that KaiOS is getting a lot of attraction — people should be aware of that brand. Go check it online, google for KaiOS devices, and you will see that it’s actually bringing the modern web into a feature phone from factor.
Kenji Baheux: And so the idea is that the lowest end of the smartphone is still too expensive for a lot of users, and so by bringing something that people can use and get connected to on a feature phone from factor, like carriers can lower the price points where a lot more users can get online. So I think this is still going to be the case for a long time, and so having to be mindful about low-end devices and slow connectivity because as more people get online, the infrastructure should keep up but it’s going to be very hard. All of these programs are still going to be a thing for a long time, I think.
Vitaly: When I was in Indonesia, by the way, I was surprised about one thing because it’s the first time when I experienced it, and it was the fact that I would go online and we’d get a SIM card and then there would be a Facebook Internet and everything else. Essentially, whenever I go through the gates of Facebook and I try to, you know, going to click on the links and all that, it’s free. But then as long as I want to type in anything else in my URL bar, I have to pay. So this is where I actually got to be hit almost by the role that net neutrality has and how it’s actually not respected really in those countries where you have to pay more for access in certain parts of the web. In terms of net neutrality, how do you see things there? Because I’ve only been to Indonesia where it happened to me. Is that a common thing that we have a Facebook Internet in many places around the world?
Kenji Baheux: So I believe this is part of something that was called Facebook Basics. I don’t know if it’s still the same name, but I’ve seen different countries where you can get online for free but you only have access to a few websites. And I’m just guessing that it’s a deal between those websites and the carrier. The stats that we have indicate that it only gets, like, a lot of people would just move away from that very soon, like quickly because as they get to hear from their friends and family about all the different things that they are able to do, they quickly realize that what they have is like very limited. And so as the purchasing power like grows, they do like pay a few additional like quota, not maybe for the full month, and eventually at some point they will be able to do so, but there is an appetite for getting beyond this like few websites sites that are available for free.
Vitaly: Yeah. And then maybe the final one, Kenji, and I will let you go, and free… So, if you look forward, let’s say in a few years from now, and maybe if you look back into that interview when I asked that question, what would you like to see changed in the next two years? Is there anything on the web that you desperately want to fix or something that kind of bothers you for quite a bit of time where you are spending all your time and efforts and you know, you’re in the nighttime when you can’t sleep, and just to solve that thing… If you had to, if you could solve just one thing for good on the web, what would it be?
Kenji Baheux: That’s a tough one. I feel that the web in general is still, like, we say that web is like very low friction and it is in a sense because everything is just like one link away. And so, and also there’s like no new install phase, it’s very safe and secure, right? But at the same time, on mobile, a lot of time it’s very frustrating because you have to wait and the pages load very slowly, the UX is not always great… So I hope that the work we do will eventually get us in a place where the web feels like instant, seamless, and delightful. And I’m wondering if there is something that is missing, which is some of the, like the native apps are on, you know, like do provide a better user experience cause I feel they have the incentive to do so to like things like ratings and reviews, right? There is a way to know where you are falling off the path, like what is wrong about my app? How can I fix it? And also you have the incentive to do it because there is like rankings and people can see what other people think about your app, and so I’m wondering if there is something on the web that is missing there where we could get more signals from users and help the web get better based on that, and so I would like to, to get some feedback on that and what people think about this idea.
Vitaly: Oh, that sounds exciting. So I guess that maybe that’s something you’ll bring up in your session on October 1st at View Source in Amsterdam, and I can’t wait to hear more insights about the web in different parts of the world because the web is much bigger than just us sitting here in fancy offices in front of wonderful displays. Alright, Kenji, thank you so much for being with us today, and thanks to everyone for watching as well. I’m looking forward to the next one and I’m looking forward to seeing you in Amsterdam.
Vitaly: Thank you, Kenji. Bye!
Kenji Baheux: Thank you, bye!

FREQUENTLY ASKED QUESTIONS
1- Does this course cover ASP.NET Core 1.0?
No! Once you master ASP.NET MVC 5, you can quickly get up to speed with ASP.NET Core. Mosh has a follow up course on Udemy called “Build a Real-world App with ASP.NET Core and Angular”. In this course, you’ll get up to speed with ASP.NET Core in the context of building a real app from A to Z.
2- Why should I pay for this course when there are lots of free tutorials available?
Free tutorials and YouTube videos are free for a reason. They introduce you to a few concepts here and there, but soon you’ll find yourself jumping from one tutorial to another to fill the missing gaps. By taking a perfectly-structured course, you’ll be confident that you’re in good hands, right from the beginning all the way through to the very end. You pay for saving your precious time: the time that you can spend on the things you love.
Plus, many of these free tutorials, including tutorials published by Microsoft on the official ASP.NET website, teach you poor practices. Throughout this course, Mosh points out some of these poor practices and explains in technical terms why you should avoid them.
WHAT OTHER STUDENTS WHO HAVE TAKEN THIS COURSE SAY
“The is course is very much worth your time and money. Mosh did an outstanding job explaining each aspect of MVC 5 as well as introducing and using other technologies such as Web API. I’ve been working with MVC since it’s release but felt I needed a refresher course and this was excellent. I would also recommend it to developers just getting into MVC as well because Mosh does a great job of explaining the concepts behind what you’re learning. I really enjoyed it and highly recommend it.” -Scott Smith
“Course teaches exactly what the title promises to teach. Quality of production, content, and lectures are excellent! Explanations of the how and why are also a nice touch!” -Pierre Gadea
“Mosh never disappoints. Clear explanations. Exercises that will test you knowledge. Great instruction as always. I also love that he includes shortcuts and best practices. Worth the time and money!” -Lara Caves
“Amazing course from Mosh! After I finished the C# series, I moved directly to this course and learn so much and even developed a successful web app in my internship! Thanks Mosh for a great course!!” -Menny Atia
“I’ve been into web development for more than 15 years, but until recently I was totally new to ASP.NET MVC. Before taking this course I tried other courses, but these were either too complicated for a beginner or didn’t cover all the necessery informations needed to get started. This is an excellent course to begin with ASP.NET MVC that covers everything you need to create a real world project. The prerequisites are a good understaning of C# (OOP, Lambdas, LINQ…) , Javascript and JQuery” -Marko Pavic
“Professionally structured, carefully planned course. Passionate, engaging instructor with great communication skills. Best course I’ve ever had on Udemy so far. I would love to take the follow-up course on architecture and testing mentioned in the final video.” -Istvan Voros
“One of the best courses i have ever taken,Recommend for every C# developer through his all the courses in Udemy. They are eye-openers and it will change the way you think about Programming.After taking his courses ,with in a span of one month i have a cracked a interview in one of the Big 4 with 70% hike.” -Rama Reddy
