The Story of KLogs: What happens when an Mechanical Engineer codes

Since i no longer work at Wearhouse Automation Startup (WAS for short) and havnt for many years i feel as though i should recount the tale of the most bonkers program i ever wrote, but we need to establish some background

WAS has its HQ very far away from the big customer site and i worked as a Field Service Engineer (FSE) on site. so i learned early on that if a problem needed to be solved fast, WE had to do it. we never got many updates on what was coming down the pipeline for us or what issues were being worked on. this made us very independent

As such, we got good at reading the robot logs ourselves. it took too much time to send the logs off to HQ for analysis and get back what the problem was. we can read. now GETTING the logs is another thing.

the early robots we cut our teeth on used 2.4 gHz wifi to communicate with FSE's so dumping the logs was as simple as pushing a button in a little application and it would spit out a txt file

later on our robots were upgraded to use a 2.4 mHz xbee radio to communicate with us. which was FUCKING SLOW. and log dumping became a much more tedious process. you had to connect, go to logging mode, and then the robot would vomit all the logs in the past 2 min OR the entirety of its memory bank (only 2 options) into a terminal window. you would then save the terminal window and open it in a text editor to read them. it could take up to 5 min to dump the entire log file and if you didnt dump fast enough, the ACK messages from the control server would fill up the logs and erase the error as the memory overwrote itself.

this missing logs problem was a Big Deal for software who now weren't getting every log from every error so a NEW method of saving logs was devised: the robot would just vomit the log data in real time over a DIFFERENT radio and we would save it to a KQL server. Thanks Daddy Microsoft.

now whats KQL you may be asking. why, its Microsofts very own SQL clone! its Kusto Query Language. never mind that the system uses a SQL database for daily operations. lets use this proprietary Microsoft thing because they are paying us

so yay, problem solved. we now never miss the logs. so how do we read them if they are split up line by line in a database? why with a query of course!

select * from tbLogs where RobotUID = [64CharLongString] and timestamp > [UnixTimeCode]

if this makes no sense to you, CONGRATULATIONS! you found the problem with this setup. Most FSE's were BAD at SQL which meant they didnt read logs anymore. If you do understand what the query is, CONGRATULATIONS! you see why this is Very Stupid.

You could not search by robot name. each robot had some arbitrarily assigned 64 character long string as an identifier and the timestamps were not set to local time. so you had run a lookup query to find the right name and do some time zone math to figure out what part of the logs to read. oh yeah and you had to download KQL to view them. so now we had both SQL and KQL on our computers

NOBODY in the field like this.

But Daddy Microsoft comes to the rescue

see we didnt JUST get KQL with part of that deal. we got the entire Microsoft cloud suite. and some people (like me) had been automating emails and stuff with Power Automate

This is Microsoft Power Automate. its Microsoft's version of Scratch but it has hooks into everything Microsoft. SharePoint, Teams, Outlook, Excel, it can integrate with all of it. i had been using it to send an email once a day with a list of all the robots in maintenance.

this gave me an idea

and i checked

and Power Automate had hooks for KQL

KLogs is actually short for Kusto Logs

I did not know how to program in Power Automate but damn it anything is better then writing KQL queries. so i got to work. and about 2 months later i had a BEHEMOTH of a Power Automate program. it lagged the webpage and many times when i tried to edit something my changes wouldn't take and i would have to click in very specific ways to ensure none of my variables were getting nuked. i dont think this was the intended purpose of Power Automate but this is what it did

the KLogger would watch a list of Teams chats and when someone typed "klogs" or pasted a copy of an ERROR mesage, it would spring into action.

it extracted the robot name from the message and timestamp from teams

it would lookup the name in the database to find the 64 long string UID and the location that robot was assigned too

it would reply to the message in teams saying it found a robot name and was getting logs

it would run a KQL query for the database and get the control system logs then export then into a CSV

it would save the CSV with the a .xls extension into a folder in ShairPoint (it would make a new folder for each day and location if it didnt have one already)

it would send ANOTHER message in teams with a LINK to the file in SharePoint

it would then enter a loop and scour the robot logs looking for the keyword ESTOP to find the error. (it did this because Kusto was SLOWER then the xbee radio and had up to a 10 min delay on syncing)

if it found the error, it would adjust its start and end timestamps to capture it and export the robot logs book-ended from the event by ~ 1 min. if it didnt, it would use the timestamp from when it was triggered +/- 5 min

it saved THOSE logs to SharePoint the same way as before

it would send ANOTHER message in teams with a link to the files

it would then check if the error was 1 of 3 very specific type of error with the camera. if it was it extracted the base64 jpg image saved in KQL as a byte array, do the math to convert it, and save that as a jpg in SharePoint (and link it of course)

and then it would terminate. and if it encountered an error anywhere in all of this, i had logic where it would spit back an error message in Teams as plaintext explaining what step failed and the program would close gracefully

I deployed it without asking anyone at one of the sites that was struggling. i just pointed it at their chat and turned it on. it had a bit of a rocky start (spammed chat) but man did the FSE's LOVE IT.

about 6 months later software deployed their answer to reading the logs: a webpage that acted as a nice GUI to the KQL database. much better then an CSV file

it still needed you to scroll though a big drop-down of robot names and enter a timestamp, but i noticed something. all that did was just change part of the URL and refresh the webpage

SO I MADE KLOGS 2 AND HAD IT GENERATE THE URL FOR YOU AND REPLY TO YOUR MESSAGE WITH IT. (it also still did the control server and jpg stuff). Theres a non-zero chance that klogs was still in use long after i left that job

now i dont recommend anyone use power automate like this. its clunky and weird. i had to make a variable called "Carrage Return" which was a blank text box that i pressed enter one time in because it was incapable of understanding /n or generating a new line in any capacity OTHER then this (thanks support forum).

im also sure this probably is giving the actual programmer people anxiety. imagine working at a company and then some rando you've never seen but only heard about as "the FSE whos really good at root causing stuff", in a department that does not do any coding, managed to, in their spare time, build and release and entire workflow piggybacking on your work without any oversight, code review, or permission.....and everyone liked it

Government OS Whitepaper

I didn't know what else to call it; maybe they'll call it "MelinWare" and then somebody will invent a scam under that name for which I will inevitably be blamed.

We have a demand for systems Government and Corporate alike that are essentially "Hack Proof". And while we cannot ensure complete unhackability...

Cuz people are smart and mischievous sometimes;

There is growing need to be as hack safe as possible at a hardware and OS level. Which would create a third computer tech sector for specialized software and hardware.

The problem is; it's not profitable from an everyday user perspective. We want to be able to use *our* devices in ways that *we* see fit.

And this has created an environment where virtually everyone is using the same three operating systems with loads of security overhead installed to simply monitor what is happening on a device.

Which is kind of wasted power and effort.

My line of thinking goes like this;

SQL databases are vulnerable to a type of hack called "SQL Injection" which basically means If you pass on any text to the server (like username and password) you can add SQL to the text to change what the database might do.

What this looks like on the backend is several algorithms working to filter the strings out to ensure nothing bad gets in there.

So what we need are Systems that are like an SQL database that doesn't have that "Injection" flaw.

And it needs to be available to the Government and Corporate environments.

However; in real-world environments; this looks like throttled bandwidth, less resources available at any one time, and a lot less freedom.

Which is what we want for our secure connections anyway.

I have the inkling suspicion that tech companies will try to convert this to a front end for their customers as well, because it's easier to maintain one code backend than it is for two.

And they want as much control over their devices and environment as possible;which is fine for some users, but not others.

So we need to figure out a way to make this a valuable endeavor. And give companies the freedom to understand how these systems work, and in ways that the government can use their own systems against them.

This would probably look like more users going to customized Linux solutions as Windows and Apple try to gobbleup government contracts.

Which honestly; I think a lot of users and start-up businesses could come up from this.

But it also has the ability to go awry in a miriad of ways.

However; I do believe I have planted a good seed with this post to inspire the kind of thinking we need to develop these systems.

Slingshots for a Spider

I recently finished (didn't take the test, I was just stumbling through the course, open mouthed and scared) the ineffable WEB-300: Advanced Web Attacks and Exploitation, from the magnanimous OffSec, which is the preparation course for the Offensive Security Web Expert certification (OSWE). The image is a very cool digital black widow spider, which makes sense, because the course is teaching you how to be an attacker on 'the web'.

As scared as I am of spiders, I am enamored by this course. Enough to stare at it for two years then finally take it and complete it over one grueling year. It covers things like: Blind SQL Injection - setting things up in a program called Burpsuite, to repeatedly try sending various things, then clicking a button, and seeing how a website answers, whether it gives us info or errors (which is more info!)

Authentication Bypass Exploitation - skirting around the steps that websites use to make sure you are who you say you are, like taking a 'reset password' click of a button, knowing some admin's email, and getting a database to spit out the token so we can get to the website to reset the password before the admin.

and Server-Side Request Forgery - making a server (someone else's computer in charge of doing real work instead of messing around with a human) ask its connections and resources to get something for you.

Now I know what you're probably thinking: Holy cow, where to even start? If you're not thinking that, congratulations. If you are, I've the answer: Tools. No spider is eating flies without sensing, lurking, biting... this metaphor to say: No one's doing it by hand with no help.

So what tools are helpful? How do you know what's good, what's useful, what's a dime a dozen, what's only going to do part of what you want versus all of it...

Luckily the fan favorites are famous for a reason. Just about anything you'd need is already downloaded into Kali Linux, which is jam packed with much, much more than the average hacker even needs!

Tools are dependent on what you need to do. For this class we need to inspect web traffic, recover source code, analyze said code of source, and debug things remotely.

Inspecting web traffic covers SSL / TLS and HTTP. SSL is Secure Sockets Layer and TLS is Transport Layer Security. These are literally just protocols (rules! internet rules that really smart people spent a lot of time figuring out) that encrypts traffic (mixes and chops and surrounds your communication, to keep it safe and secure). HTTP is the hypertext transfer protocol, which is another set of rules that figures out how information is going to travel between devices, like computers, web servers, phones, etc.

But do you always follow the rules? Exactly. Even by accident, a lot can fall through the cracks or go wrong. Being able to see *exactly* what's happening is pivotal in *taking advantage* of what's not dotting the i's and crossing the t's.

Possibly the most famous tool for web hacking, and the obvious choice for inspecting web traffic, is Burp Suite. It gathers info, can pause in the middle of talking to websites and connections that usually happen behind the scenes in milliseconds, like manipulating HTTP requests. You can easily compare changes, decode, the list goes on.

Decompiling source code is the one where you could find a million things that all do very specific things. For example dnSpy can debug and edit .NET assemblies, like .exe or .dll files that usually *run*, and don't get cracked open and checked inside. At least not by a normal user. .NET binaries are easier to convert back to something readable because it uses runtime compiling, rather than compiling during assembly. All you have to do is de-compile. It's the difference between figuring out what's in a salad and what's in a baked loaf of bread. One's pretty easy to de-compile. The other, you'd probably not be able to guess, unless you already knew, that there are eggs in it! dnSpy decompiles assemblies so you can edit code, explore, and you can even add more features via dnSpy plugins.

Another type of code objects useful to analyze are Java ARchive or JAR files. Another decompiler that's good for JAR files is JD-GUI, which lets you inspect source code and Java class files so you can figure out how things work.

Analyzing source code is another act that can come with a lot of options. Data enters an application through a source. It's then used or it acts on its own in a 'sink'. We can either start at the sink (bottom-up approach) or with the sources (top-down approach). We could do a hybrid of these or even automate code analysis to snag low-hanging fruit and really balance between time, effort and quality. But when you have to just *look* at something with your *eyes*, most people choose VSCode. VSCode can download an incredible amount of plug ins, like remote ssh or kubernetes, it can push and pull to gitlab, examine hundreds of files with ease, search, search and replace... I could go on!

Last need is remote debugging, which really shows what an application is doing during runtime (when it's running!). Debugging can go step-by-step through huge amalgamations using breakpoints, which can continue through steps, step over a step, step INTO a step (because that step has a huge amalgamation of steps inside of it too, of course it does!), step out of that step, restart from the beginning or from a breakpoint, stop, or hot code replace. And the best part? VSCode does this too!

Remote debugging lets us debug a running process. All we need is access to the source code and debugger port on whatever remote system we happen to be working in.

Easy, right? Only a few tools and all the time in the world... WEB-300 was mostly whitebox application security, research, and learning chained attack methods. For example, you'd do three or seven steps, which incorporate two or four attacks, rather than just one. It's more realistic, as just one attack usually isn't enough to fell a giant. And here there be giants. Worry not: we've got some slingshots now.

The next step is seeing if we can get them to work!

Harley Frankston: Teaches Web-programming, Sql And Database Design, Php, Html, And Css

Data Engineers are liable for constructing and maintaining data pipelines, in addition to the efficiency of both batch or real-time processing on gathered and saved data. However, data is only online transactions and financial privacy as valuable if it is interpreted accurately. That’s why HyperionDev and the University of Stellenbosch have collaborated to bring you this highly intensive and skills-focused online data science course.

For instance, a desk data the primary keys as student_id and the subject_id of each learner. The multi-step course of stores data in a tabular kind, which helps eliminate redundant data from the relation tables. In this weblog, we’ll talk about database design, its importance, lifecycle, and methods, together with the necessary thing steps you can take to develop a robust database design in your enterprise. In many articles and tutorials, you may see that one needs to find a business-relevant area or helpful to the tip uses as the first key. For example, you have to use main key as social security number, particular person taxation number, firm ID, a part quantity for commerce merchandise, and so forth. So, you will need to store data in separate fields, which makes it simpler to retrieve data.

model which accurately refl ects the person necessities and the wants of the enterprise. In this stage we now have to consider how each relation is saved and the way the information is accessed. Given their crucial role in database design, business guidelines should not be established casually.

To make that process work, it might be an understatement to say Verbeeck views SQL Server database design as essential. “We can speak hours and days and even weeks about database design,” he stated in a current webinar on SQL Server development and design finest practices. When it involves internet & database design, we specialize in constructing visually appealing web sites with the expertise of the user in thoughts. The means this mapping is mostly carried out is such that every set of associated data which depends

TASK DM has statistical programmers to generate the tables, listings and figures to answer the analysis question. Upskill your self or your organization by enrolling for the Microsoft sql server course, while you’re working. Thus regardless oltp of where you would possibly be, we come to you and give the tools to move up in your company.

Sometimes when data is modified you may be altering other data that isn't seen. For instance, in a listing of names and addresses, assuming a state of affairs where multiple people can have the same handle, however data base design one individual can't have more than one tackle, the address relies upon the name. Because an handle is decided by a name, an address is taken into account dependent on a

Most of the companies we take pleasure in on the internet are offered by net database functions. Web-based e mail, online buying, forums and bulletin boards, company websites, and sports activities and news portals are all database-driven. To build a modern website online, we are going to develop a customized build database software. Prepare in your Database certification exam with our online short course.

I am so excited for your upcoming women- writers' app and api!

Hiya! 💗

Thank you so much! My goal is to provide a platform that celebrates and amplifies the voices of women writers, making it easier for everyone to discover and engage with their work. I appreciate your support!

However, the project is currently on-hold as I am trying to find a proper cloud-based database service that I can use with little money. I have come to either Google Cloud SQL or Amazon RDS to store the table's data remotely. Then again, I need to figure out how to use it 😅

Then I have to get to learning how to make an API from scratch. Since I want to use JavaScript, just to expand my knownlege on JavaScript even further, I would have to use a server-side JavaScript runtime environment like Node.js, which allows me to write server-side code using JavaScript.

Someone on here has also suggested I market/get traffic for this project so I will also have to plan how I can do that! Thinking maybe creating a mini webpage explaining what the project is, get help for filling out the datatable (really happy as there are a lot of women writers out there), might get help for setting up the official webiste of "Her Story".

Basically there's a lot to do, and I didn't expect it to be easy! Previous projects I have done have been fairly "easy" so I wanted a challenge and here it is! I want to take my time with this project, I don't want to mess up too many times on something like this - too precious to me!

C# Late Project | C# Study

Hello Hello! ✪ ω ✪

I just thought it would be cool to give an update on my current (late) c# project my apprenticeship gave me, which was due 2nd May and which I still haven’t completed, and just talk about where I am at with the project!

The actual project is:

▢ Completely create a ‘search user’ webpage

☑ Create a textbox in which you can search for the user by their forename

☑ Create a dropdown list - in which you will be given the option to pick which particular user you want information on

☑ Create a gridview - in which a table is displayed with the selected user’s information

▢ The table should have these columns: Name | Department | Location | Email | Extension No. | Job Role

▢ Use CSS3 to change how the table looks - anything but the default styling

Key Knowledge To Know:

▢ C# x SQL - How to retrieve data from a database from SSMS (SQL Server Management Studio)

▢ ASP.NET

▢ Gridview, Dropdown List, Textbox, HTML, CSS

This is what I have so far:

[ 1 ]

[ 2 ]

[ 3 ]

* Don’t worry, the actual emails and information are fake! I am using a test database for this!

Problem: It’s not done because I can’t figure out how to add the ‘Job Role’ column to the table because some people have lots of roles and for some reason, I can’t merge the rows into one to fit in the column as one row. 

After I figure out that problem, I will move on to the CSS3 part and make it look like the page from the actual company’s website.

What was I having issues with before?

I am a slow learner, even slower if I’m ill for a long time and having meltdowns whenever things go wrong and I can’t find out why, so having all those issues go on for over a month made things worse. 

I had issues with binding the textbox and the dropdown list together. They just wouldn’t work at all. I couldn’t find out why. That led to me thinking I’m not right for programming if I couldn’t find out why I couldn’t bind two elements together. It’s so simple and it was but my brain couldn't work out what was going on! ＞︿＜

The solution to that? I didn’t remove the [ ] from the SQL query I put into the .cs file I was working on: 

The SQL query in general:

"SELECT Users.Forename + ' ' + Users.Surname AS [Name], Users.ID FROM Users WHERE Forename like '%'+@Forename+'%' ORDER BY [Name]";

I initially wrote in Visual Studio:

DDLSelectUser1.DataTextField = "[Name]";

The correct way was: 

DDLSelectUser1.DataTextField = "Name";

THAT WAS IT! I was stuck on this for a good week! I also couldn’t get help from my colleagues because my apprenticeship said this is an independent project i.e figure things out yourself, no matter how long it took! 

The website that helped me the most with this problem was: Fill ASP.Net GridView on Selecting Record From DropDownList which helped select and populate the grid!

Everything has been hectic but once I overcome this new problem of the Role column, everything will be fine and once I complete the homework I have to write a one-page essay on the whole experience - I would just be complaining!

But, overall this has definitely been a learning experience and makes me wonder if my fellow developers at work go through the same stress when they can’t find the answer to their tasks? 〒▽〒

[tototavros]

speaking of the job, it’s really weird that there was any amount of onboarding aside from “here’s the repos, here’s your accounts, set up 2fa, etc.” and a guy actually took like an hour and a half on guiding me through the codebase in general and showed me the functions i should parallel for my first task 

i’m not used to any of that! first company i worked for, i didn’t share any codebase with my coworkers after someone handed their project off to me and i relayed to the manager that i didn’t know how long it’d take to fix all his compiler errors & also it was haskell written like python. they let me pill them on applying category theory to enterprise blockchains after that which was nice even though i had no idea what the hell i was doing. 

second company had ~500kloc of haskell and i was basically dropped into the repo with no explanation of anything and told to figure out how to add on some more CRUD to the servant shit. i didn’t know any servant, and not enough sql to do a join. i’d ask if there was some functionality that was built while searching for it, maybe get a response in a day that pointed to a 1kloc file of haskell. ripgrep became my friend, and thank fuck someone finally set up a local hoogle server. 

job after that was plutus contracting. if you know plutus, you know the hell i was in. if you don’t, i don’t know where to start with how fractally fucked it is. best of all, most of my coworkers logged off at 8am my time and didn’t log back on until 6pm. 

anyways, this is nice! it’s weird! people are friendly and accommodating so far?

UYPP: Ben Ruel's Garage Garden

Back in March, we announced the winners for our Unleash Your Potential Program, in which six participants got to configure their own System76 computer to use for their awesome projects. This first awesome project is the Garage Garden, helmed by awesome project-er, engineer, and mighty green thumb Ben Ruel. We sat down with Ben to see how his project has been growing on the Meerkat.

Can you tell us about the Garage Garden project? What's it all about?

I spent a career with the Coast Guard and came up here—my final tour with the Coast Guard was in Juneau. Being in southeast Alaska, we’re constrained with what they call off-the-road systems, and the only way in or out of town is by boat or by plane. So all of our food comes up here by barge for a small nominal fee, or by aircraft for an incredibly large fee.

When I came up to Juneau with my wife and kids 11 years ago, we noticed that by the time our produce gets up here, it’s lived on a barge a week, two weeks out of Seattle, and you have no shelf life left on them. We started trying to grow food within the first year of getting here, and we came to the conclusion pretty quickly that with 300 days plus of rain every year, outdoor growing wasn’t really a viable option. That’s when we started a hobby farm in a garage growing some stuff in soil under fluorescent lights, as odd as that sounds.

Since then, we’ve progressed into hydroponics, but we’ve done it very manually. We go out every other day and take readings by hand, so I’ve been doing some research about building IOT devices that will talk back and automate some of the readings. My dream would be using it to actually control the concentration of nutrient solutions that we use. The overall goal is we’re going to build the hydroponic monitoring network of IOT devices, and use the Meerkat as a control center for the devices and a repository for all the data. We’ve also been doing some investigating behind the scenes into whether or not it could grow enough legs to become a business.

Is there a specific type of produce that you’re starting with?

We’ve been all over the road. Right now we’ve got lettuce. We’ve always got some kind of green leafy vegetables whether it’s any variety of lettuce that will grow hydro, some bok choy and tatsoi, and we’re growing kale like it’s going out of style. We’ve grown cucumbers to the point where I think I’ve harvested 65 pounds of cucumbers off of 4 plants over the last couple of months, but we’re really constrained by our size.

I live in a relatively small 3-bedroom house, and we’re just using a one-and-a-half car garage as our grow area. Right now I’ve got two tents. As funny as it sounds, cannabis is legal in Alaska and has been forever—my wife and I don’t touch the stuff, but because it’s been legalized, the infrastructure and the supplies that we need are freely available. We’re growing tomatoes in a tent that’s designed for marijuana growth. It works really well. It helps to maintain efficient temperature control; you can maintain temperature and humidity, block out extraneous light if you don’t want it, and cycle the lights on and off.

Depending on whether it’s too hot in the summer we’ll run the lights at night, and in the wintertime we’re looking for extra warmth, we can shift the cycle and run the lights during the day. Our big benefit up here is that, because Juneau’s all on hydroelectric power, electricity is really cheap.

What variables are being monitored?

With hydroponics, there’s a good number of parameters that you’ve got to try and keep track of. You’re basically diluting nutrients in a solution of as pure water as you can get. You want to keep track of things—your pH can’t be too acidic or too alkaline, for example.

The other big parameter is the electrical conductivity, or total dissolved solids. You want to make sure you’ve got the right concentration of nutrients, and that your nutrient solution isn’t salting up. As you’re adjusting pH back and forth, it’ll start demineralizing salt, so tracking that data gives you a good indication for when it���s time to dump the reservoir and start over.

We’re doing it manually now. I go out every couple of days and we take samples, and sit down and log it into a spreadsheet. The Meerkat acts as a control center for programming devices, keeping a repository of the programming for the IOT devices that we’re using (Arduinos with the esp8266 chips) as well as running different database programs as Docker containers, so that they can be spun up and knocked down fast enough as we try and figure out what the best way to move forward is. We’ve got a couple of database servers that I’ve been playing around with, trying to break from traditional SQL and looking at NoSQL type of databases.

I’m not an IT guy by trade. I’m more of an electronics guy, so I’m kind of doing it as a study-by-night type of project.

What has your experience been like with the Meerkat so far?

I’m actually completely blown away by the Meerkat’s performance. It’s astounding what that small form factor and footprint is able to do. I’ve used Linux for a number of years, and basically everybody’s heard of System76. I’ve seen Pop!_OS before and never really played with it all that much, but I’ve actually grown to love it. The feel, the ergonomics, the interface, and even down to the color schemes that come bone-stock right out of the box. They just make more sense to me. I’m looking forward to the COSMIC update after researching that to see how the differences in the workflow will affect things.

What software are you using for this project?

Right now we’re writing in Docker containers and running the Tick Stack from Influx. We’re also running Telegraf, Protograph, Capacitor, playing around with the Time Series Database, I’ve got a container running MongoDB I run with SQLite, and there’s a couple different IDEs I’ve got loaded on there as well for programming Arduinos or esp8266 chip flashing.

How was the setup process for the machine?

It was up and running within 10–15 minutes of pulling it out of the box. I actually took it to work, too. We do a lot of work with government agencies, and I’ve been doing a lot of microwave radio repair. I’ve got a pretty small workbench at our shop here in Juneau, so using the Meerkat to drive all of our test equipment to control the radio while logging data coming out of the radio, it was perfect. It had enough horsepower to remotely control the test equipment. I wasn’t pushing it all that hard, but setting it up and going back and forth between having it at home or at work, it was negligible to get it up and running.

Stay tuned for further updates from Ben Ruel’s Garage Garden and cool projects from our other UYPP winners!

hm. i should start over on that tumblr post saver. now that i actually know [literally anything at all] about webdev and web apis and shit, i bet i could do a WAY better job than my previous 'reblog 200 posts to another blog' attempt, because franlly that script sucks dick, is worthless, and i never even bothered to set it up such tjat it ran continuously (had IDEAS to run it off an rpi, but never even got ariund to figuring THAT out. jeez...)

id defijitely also want to get/make a viewer, too. because, frankly, exporting a shitton of xml or json or whatever the fuck? not even helpful at all. lame!

though, hm. i have... no idea, how to make working webpages (cuz if u cant get stuff of a certain tag whassa point)

maybe a self-contained exe that runs both the server and the client? that might not be a terrible idea

viewer levels:

literally just xml

generate a basic html file that contains all da posts

make it have css too (how?) (i dontnknow right now fuck off)

allow tag filtering based on runtime arguments (postviewer.exe -tags 'honk, fuck, kill' -reblogs false)

allow tag fiktering from within the viewer, by clicking on tags. like tumblr does jow, kinda.

search up tags, too.

would also wnana be able to capture pictures. other media forms would be good, but pictures are franjly mandatory. (i dont feel thatd be super hard tbh. download image, rename it according to the post id, have that be accessible in the folder. append a cointer for multiple images in a post)

multiple post types is a potential worry. how are dialogues handled? has the way tumblr stores / encodes posts changed since the strt (surely, right)? how are reblogs hanxled, in the code?

would probably be helpful to find or make a test blog. fkr experimentation, and testing. on a blog.

i like this idea, i feel ike its smth i could actually do AND that is actually useful. maybe i could start over christmas break. plus, if i getthis working good and reliably, maybe i could let other ppl use it, too^_^ (for showing off to irl ppl, include one of the sandsverse blogs as an example. nice and weird, but so weird it works imo? plus iirc a nice variety of post types. not so good with taghing though iirc. check that later, maybe one is betterthan the other ones.) (yeah just went and checked sandsvendor. no damn tags. cmon seymour.)

anyway. might be a good idea to slot all the posts into a database? could sort by notes and shit, that way... but it also kinda implies rails (cuz thats tje only database-oriented stuff i interact with...)

doing thus in rails feels kind of stupid. plus, load time on start? should NOT be long, prederably under thirty seconds imo. idk hlw achievavle that is with rails or an sql darabase in general, since i know my blog for example has like 30000 posts or more if u include everything. which wasnt the initial plan, but... meh.

hm. okay. so.

initial plan: save all posts on a tumblr blog with one/more of a given set of tags. eg, the set [blog, saved, later] would catch posts woth tags [blog, i hate you, five dogs] and [later, saved, i love this so much] but not [aaaaa, you you you you, two] or []. Images (and possibly other media) attached to such posts are to be saved as wrll, in a format in which they can be retrieved at time of viewing. This process must be enactable with minimal user input, beyond choosing the tags and the blog url. Posts must be saved in a non-volatile format, ie they must be retrievable not just by this program. (bare minimum)

A viewer should be included, which is capable of rendering the posts in a manner that is human-readable. Posts must have all text, tags, timestamps, and images (possibly other media) as when they were on tungle.net.

Optionally, posts ij the viewer should be sortable and filterable. Users should be able to filter by tags (and possibly also timestamps, and whether the backed-up blog is the OP of a post). Users should be able to sort by timestamp both ascending and descending (if u need to sort by anything else well nyeeeeh)

okay! so. i THINK that really the main thing that rails kr another web framework would be needed for is tgat last point, and maybe the formating. i have no idea how hard/easy adding css formatring to straight html is (probably hard lol<_<)

hmmmmmm. okay. ill be real w u here. doing this in rails feels... dumb? Im not here to build a web app.

then again, filtering by tags, sorting? those are practically what databases were MADE to do. so if i want those (and, franjly, i do!), then it may be wise to resign myself to needing to use something of that nature.

maybe i could look into what those homestuck viewer people did? thats basically the platonic ideal of what i want this to be: a familiarish interface used to sift through the wreckage of the past.

hm. well, if any of yall have any ideas, feel free to chime in! hopefulky i end up actually doing this, so any tips would be super appreciated! (esp on how to handle the iewer part <_< thas the psrt that turns this from a script to a real projext imo)

8 Trends That Will Shape Enterprise Software Development In 2021

Enterprise software development trends keep rolling year after year. Languages, architectures, frameworks, methodologies, and various other components related to software engineering advance with associated changes. The architecture of 2020 has changed, and 2021 is ready to experience a new language.

To lead the market, it’s not sufficient to just adopt the latest technologies. It is also imperative to keep pace and outrun the competition. For that, you must keep an eye on cutting-edge and emerging technologies. Enterprise software development is fast evolving to become the most dynamic area.

With 2021 rolling, expect some more updates in the enterprise software development trends. While some trends will continue with the pre-set popularity, others will be added. According to experts in the enterprise software industry, this field would zoom in on some new trends.

Enterprise Software Development in 2021

The realm of enterprise software development is ever-changing — annually, monthly, or even daily. In 2021, entrepreneurs can look forward to some significant defining shifts, which would shape this industry.

Gartner points out that the global expenditure on enterprise software will grow by approximately 10.8% and be $516.9 billion in 2021. Similarly, Statista has said that the worldwide spending on enterprise software solutions will be $517 billion.

With these towering figures, businesses should start thinking of ways to start investing in enterprise software.

Trends to Look Out For in 2021

Post Covid-19 pandemic, digital transformation will evolve and become more accelerated. More companies would adopt the facility of working from home. Hence, businesses want technologies supporting the current scenario for uninterrupted workflow.

Organizations want to create a prominent presence on multiple digital platforms. Likewise, there is a major shift towards developing applications using SaaS (Software as a Service), PaaS (Platform as a Service), and Serverless.

Thus, technical innovations will also play a critical role in untangling these complexities. Adding more abstraction makes it easier to carry this out.

Another StackOverflow study reveals that, in 2020, JavaScript was the most popular and frequently used programming language, followed by SQL and HTML/CSS.

The year 2021 will witness cutting-edge technologies surfacing, which would make this industry battle stronger.

Noted below are the eight hailed enterprise software development trends in 2021:

#1: Low-Code/No-Code EAS Development

According to the State of Software Development reports, 35.05% of respondents stated that they do not intend to use a new programming language in the next 12 months.

Drag-and-drop editors are popular these days. They earned this reputation due to low-code development. Now, non-programmers can also develop as well as implement applications sans coding.

Moving ahead, in 2021, such application development methods would gain more grounds. In 2020, even people having limited programming knowledge could create large projects through low coding or no coding methods.

In 2021, the non-programmer market will grow by as much as 28.1% YoY. According to forecasts, by 2025, the market could touch approximately $45.5 billion from the current revenue value of $13.2 billion. Businesses can also reduce costs using low-code or no-code enterprise software app development,

#2: Artificial Intelligence

AI is the newfound anchor of trade. It is most prominently used in various fields of cybersecurity because AI can quickly spot malicious activities and software to identify potential threats. It can detect suspicious IP addresses as well as data breaches.

Firms focused on cybersecurity could deploy AI as the leading trend in software. It is a crucial element for hyper-automation that improves the quality of daily living and functionalities.

Lastly, conversational IT benefits marketing, sales, and customer support teams.

#3: Native & Progressive Apps

Native apps are ruling the trends in enterprise software development. It is on the radar as it allows businesses to target new and existing smartphone users. It enhances brand performance and enhances client experience considerably over Android and iOS platforms.

Progressive Web App is the new addition to this genre of app development. Also called PWAs, the designs target CX and enhance it. Any reputed app development company would explain the benefits of PWAs, which include fast loading time, greater capabilities, alleviate bounce rate, the ability to work on devices as standalone windows, and increases chances of restriction-free browser versions for apps.

In 2021, technology will become bewitching, and progressive web apps will be the future of development.

#4: Human Augmentation

With time progressing, it is evident that human augmentation would have a hopeful future. As the trends in enterprise software grow, human augmentation takes different forms, such as AR, VR, and MR,

Augmented Reality

In 2020, AR was a huge hit. It is said that AR will hold the market in 2021 as well. Much of the success of this technology is because of its use across multiple architecture industries such as navigation, retail, and manufacturing.

Once Instagram and Facebook add the AI-layered ad filters and formats, this trend will become undeniable. It will hold much potential as well. While its virtual makeover introduces a completely diverse dimension, enterprise software development cannot lag.

Virtual Reality

If you see the number of gaming and video apps mushrooming over the last few years, you would know how big this is.

Much of the growth is the result of the enhanced benefit of VR. Virtual Reality offers users the first-person perspective along with an immersive experience of progressive computerized visions.

As predicted, several enterprises tap into the potential and overcome different issues and challenges in this trending genre. VR, however, is not just in the gaming and video industries. It is helpful across varied genres, including the training and education sector. Schools, as well as other institutions, are making their way to introduce VR into classrooms.

As far as the corporates are concerned, it is the same story. User-centrism has been the major game plan for organizations in 2020. Corporates need this incentive alone to start adopting VR.

Mixed Reality

MR is the combination of AR with VR. It holds substantial prospects in enterprise software development and custom enterprise software.

According to ARC research reports, the MR market is all set to witness an increase in CAGR of an estimated 73% from the year 2018 to the year 2023. The market size is likely to grow from 1.054 billion dollars in 2017 to 9.982 billion dollars in 2024.

MR establishes the two best forms of human augmentation — VR and AR. While VR offers an immersive user experience, AR blends digital content with the actual surroundings of users.

Today, various companies are using AR and VR, including tourism, gaming, healthcare, defense, architecture, and construction. It is the best tool for custom enterprise software.

#5: Consistent Integration & Deployment

There are still concerns about making a glitch or bug fix effectively and enabling experiments-driven lenient software development practices.

Code testing confirms agile delivery. Speedy delivery and relevant code testing for the purpose is critical as it assists the development squad to chisel its functionalities and delivers products/services swiftly across a constant cycle.

This domino effect alleviates the delivery feature cycle significantly in continuous delivery through testing and continuous deployment by automatic app updates.

#6: Big Data

Called the “elephant in the room,” Big Data, also known as the Great Responsibility or Great Power, will be more influential. Whenever data becomes the most powerful tool for any organization, it experiences great hurdles. The issue emphasizes proper data tapping and utilization to have an edge in various business dealings.

Big Data plans something new for 2021 — including Data-as-a-Service (DaaS). DaaS aims to eliminate data redundancy by confirming that businesses have access to precise data at the right time.

Nonetheless, in recent times, consumers are more aware, and their journey is well documented about data security and data utilization. Thus, for the brands that cannot reiterate credibility, the question of data security arises.

#7: Blockchain

Bitcoin caused a lot of noise on the digital front, making everyone intrigued. However, that was merely the tip of an iceberg.

Blockchain offers much more than Bitcoin and Ether. Most of the companies involved in website designing and development are moving ahead with Blockchain designing.

P2P (peer-to-peer) networks can provide transparency, decentralization, distributed ledger, and robust security features by having blockchain in the list of best practices for enterprise software development.

#8: Cloud Computing

2020 saw excellent cloud computing as businesses were more dependent on the cloud servers to keep data safe.

As we move ahead, cloud computing will evolve quickly, catering to users’ changing requirements and expectations. As a result, it will enhance the functionalities of various industries.

When enterprises choose to transform their business digitally for 2020 and further, shifting to the cloud becomes necessary and the most feasible method of storing data. However, such migrations come with evolving expectations, which require innovative cloud technologies and enhanced and robust security features.

Therefore, cloud computing will take the last stride to become the top trend of enterprise software development.

Conclusion

Such trends in enterprise software development and custom enterprise software prepare a brand for impending success. Nonetheless, the final step is to implement these development trends strategically. The best step forward is to choose an experienced and proven enterprise software company to carry out this implementation process.

New framework seems to have performance issues

This version of ABP for the new Safari framework unfortuantely seems to kill performance on my computers. Maybe it’s partially related to them being a bit older (one is a Mid 2011 Mini, the other is a 2012 iMac), but with ABP enabled I can’t even open a new tab/window and type a URL into the bar and expect Safari to accept the input without having to hold down the return key until it goes or wait a minute after opening a new tab or window. I also noticed that using Twitter was jumpy and lagged even with simple typing, it felt like all the dynamic content it relies on was just struggling to be processed through whatever framework Apple is forcing. Hopefully the devloper can figure out the performance issues because it’s really, really bad now.

By Ramblin'Rose

why isn’t this working?

I have ABP and it wasn’t perfect but worked fairly well for my needs. Recently, it simply disappeared. (I see someone else said that could be from the latest iOS update, but I don’t have that on my desktop yet). When I tried to reinstall, it showed me two boxes to check. The way I read it, if you checked the box that said you wanted the icon visible in the toolbar, it would be able to read sensitive information of all kinds on any page. What good is an app of any kind that allows for that?! As it was, with only the one box checked, it only blocked very few ads, and I was still getting requests from sites to be whitelisted without being able to fnd any way to do it. I’ve got all kinds of garage showing up on my Facebook page, and you guys have ruined what was a reasonable product. WHY?

By PeopleRsad

Still works for me

Almost didn’t download the new version based on the recent reviews, however after looking at the other apps here that claim to be ad blockers I didn’t’t see too many alternatives. I decided to go ahead and get the new version and so far its pretty much the same as the old version, lots of ads blocked. I’m happy, just make sure you go through the simple set-up.

By achilds19

Works well but

After much research, I understand the issue with Apple changing the rules on the devs so they had to build this app from scratch. Works well for me so far, except for one annoying problem. I use Yahoo mail and it's not hiding the ad that appears in the top line of the inbox even with unchecking the Acceptable Ads box, which is super annoying. I know the devs are watching these reviews, so if someone can point me to an extension or something that will fix that, I'd appreciate it. Was using AdGuard and it fixed that problem, but that app behaves like spyware and is constantly running in the background even after you close Safari.

Application Software

One of the main things to comprehend about the expression "application programming" is that it is extremely wide.

Application programming is ordinarily characterized as any program or number of projects intended for end-clients. That is it, more or less.

In that sense, any end client program can be called an "application." Hence the well established saying: "there's an application for that."

Types of Software Reviews

Individuals frequently utilize the expression "application programming" to discuss packages or gatherings of individual programming applications, utilizing an alternate term, "application program," to allude to singular applications.

That is on the grounds that "program" relates to a discrete, countable single unit, while "programming" is frequently used to allude to more than one individual program.

Instances of utilization programming incorporate things like Microsoft Word, Microsoft Excel, or any of the internet browsers utilized explore the Internet … or the real programming suites themselves, on the off chance that they are planned for end clients.

Another approach to comprehend application programming is to balance it with other programming. In an extremely fundamental sense, each program that you use on your PC is a piece of utilization programming.

The working framework, then again, is framework programming. Verifiably, the application was by and large conceived as PCs developed into frameworks where you could run a specific codebase on a given working framework.

The product is a sort of projects that empower a client to play out some particular errand or used to work a PC. It coordinates every one of the fringe gadgets on a PC framework – what to do and how to perform work. Without Software, we can't work equipment and play out any estimations. A PC framework can be isolated into three parts: the equipment, the product and the clients. The product can be additionally separated into principally two sections: Application programming and System Software. Exposed utilization of equipment isn't simple, so to make it simple programming is made.

Framework Software: System Software (a kind of PC program) gives a stage to run PC's equipment and PC application to use framework assets and take care of their calculation issue. It is written in a low-level language, similar to low level computing construct so it can undoubtedly interface with equipment with fundamental level. It controls working of fringe devices.System programming go about as a scheduler for the execution of the cycles and organize the arrangement as per their need and I/O gadgets prerequisite and making of the interaction. The most popular illustration of framework programming is the working framework (OS).It answerable for deals with the wide range of various projects on a PC.

Application Software: Applications programming is equipped for managing client data sources and causes the client to finish the errand. It is likewise called end-client programs or just an application. It dwells above framework programming. First client manage framework programming after that he/she manages application programming. The end client utilizes applications programming for a particular reason. It customized for straightforward just as unpredictable errands. It either be introduced or access on the web. It tends to be a solitary program or a gathering of little projects that alluded to as an application suite. A few instances of Application Software are Word handling programming, Spreadsheets Software, Presentation, Graphics, CAD/CAM, Sending email and so on

Sorts of Application Software: According to the need of clients it is ordered into following kinds.

1) Presentation Software: Presentation program is a program to show the data as slides. We can add text, illustrations video and pictures to slides to make them more instructive.

The product has three segments:

1) Text editorial manager for contributing and arranging text.

2) Inserting designs, text, video and other mixed media documents.

3) Slideshow to show the data.

Introduction programming encourages the moderator to give their thoughts ease and visual data straightforward. Illustration of introduction programming: Microsoft's PowerPoint and Apple's Keynote.

2) Spreadsheet Software: Spreadsheet programming is utilized to perform control and figurings. In bookkeeping page programming information is put away in convergence line and segment. The crossing point of line and section is known as a cell. The cell marked with the line and segment name like A1, A2 and so forth While entering information into the phone, we can likewise characterize the information esteem like content, date, time, number. It gives numerous recipe and capacity to perform estimations like math activities, intelligent tasks, text activity and so forth It gives diagrams, charts to show information graphically. For instance Microsoft Excel, lotus 1-2-3 for windows and number for MAC OS.

Difference between System Software and Application Software

3) Database Software: Database is an assortment of information identified with any applications. Today is climate each application has some data set where information with respect to clients put away. For this reason, we utilized information base programming. At the point when we work the application information is gotten to from the data set, and after control, it gets back put away in the data set.

Data set Management System (DBMS) programming apparatus utilized for putting away, changing separating and looking for data inside an information base. MySQL, MS Access, Microsoft SQL Server and Oracle is the case of data set application Software.

Build a Mobile Video Chat Framework With Nex Gen Media Server (NGMS) API

Software giants, like Google are disrupting the otherwise safe and established players in the mobile application development business. Newcomers like Android have led to significant structural changes on the future of mobile application development by imposing their rules. This changed environment not only brings additional opportunities, but also adds certain constraints. Developers today, need to assess their options and find out how they can benefit from this changed environment.

While mobile computing has caught the attention of application developers, there has been very little work done to examine the programming ease of these technologies. Here we will take a look at two apkpure vip of the most widely available mobile development environments - Android and Windows Mobile and explore and assess these options from a developer's perspective.

Android

Android was released by Google in 2007, as an open source platform for mobile software development for smartphones. The Android platform was released as part of the Open Handset Alliance. The primary aim of this alliance was to set up open standards for smartphones. Android is basically a Linux based, open source operating system for mobiles. As a mobile operating system it allows developers to create managed codes in Java, by using Java libraries developed by Google. Not only does Android provide a mobile operating system including a development environment, it also offers a custom virtual machine known as the Dalvik Virtual Machine for running applications as well as acts as the middleware in between the operating system and the code. When it comes to application development, Android facilitates the usage of 2D as well as 3D graphic libraries, advanced network capabilities such as 3G, Edge and WLAN and a customized SQL engine for continual storage.

Windows Mobile

Developed by Microsoft, the Window Mobile is an operating system for mobile devices. Based on the Microsoft Windows CE 5.0, Windows Mobile is used as an operating system on many smartphones, PDAs and touch screen devices. Windows Mobile facilitates the creation of custom written applications in managed as well as native codes. The Application Programming Interface (API) in Windows Mobile is extensible and has rich features along with a programmable layer. Besides that Windows Mobile also takes advantage of the capabilities provided by Microsoft.Net environment.

We will compare these platforms and closely examine their strengths and weaknesses. The platforms will be compared on the basis of implementation and performance aspects as well as developer support. We have chosen these criteria for the comparison as they represent the most important aspects when it comes to mobile software developers.

Implementation

We will use persistent storage as the basis for comparing the implementation aspect. The technology used for persistent storage in mobile technology varies between various mobile development environments. Both Windows Mobile and Android have the ability to use an on-device database which facilitates easier manipulation as well as extraction of data. Also, as far as local file storage is concerned both environments support memory cards for additional storage space. However, the difference lies in the way the storage space is exploited. While Android cannot install applications on memory cards, Windows Mobile allows it. Both Android and Windows Mobile platforms have a relational database. Also, in both the platforms the libraries have quite a few useful persistence features. Once the libraries have been initialized, access to database is available via an object oriented interface which can be easily accessed by developers.

Performance

Performance figures are important for both users as well as developers. The performance comparison of the two platforms will be carried out based on the file size. The basic purpose of measuring file size is to get a better idea of the configuration as well as the run time dependencies that are included in packaged applications.

Android applications come packaged in apk (Android Package) files. The .APK file generally has a group of .DEX (Android program files) files, which operate like a single application file for usage within the Android platform. The .APK file is basically the compressed version of the contents in the 'Androidmanifest.xml' file.

Windows Mobile applications make use of cab-files for application packaging and deployment. The first step while making a distributable file, involves packaging the application in a CAB (Cabinet) file. This CAB file can be deployed to other devices where it can be expanded and installed. A CAB file is basically an executable archive which contains the application, resources, dependencies like DLLs and other resource files.

A comparative study of mobile development environments was conducted by Tom Morten Gronli, Jarle Hansen and Gheorghita Ghinea, of Brunel University, London. In this comparative study, a demo example application was created in both the Windows Mobile and Android development platforms to better illustrate the deployment file size for each application. The demo example application was a simple program which printed a line of text on the screen. The result from the code example was as follows:

The deployment size of the demo application in the Windows Mobile environment was 2.8 KB.

The deployment size of the demo application in the Android environment was 9.3 KB.

The file sizes as denoted were without any obfuscator or shrinker software. This is the type of file that an end user would either download or get shipped and then installed on his/her device. As can be seen from above, the demo application in Windows Mobile had a file size of 2.8 KB while Android was approximately three times the size at 9.3 KB. This serves as an indication of the total amount of configuration files and runtime dependencies which must be bundled along with each of the client applications. When it comes to the number of lines of code, Windows Mobile required only 11 lines whereas Android needed 28.

Developer Support Comparison

Developer support is a highly important aspect when it comes to gaining speed as well as quality during the development process. While both mobile development platforms do have similarities, there are some unique differences in developer support. The differences become clearer when we take the integrated developer environment (IDE) and the tooling into consideration.

The only choice for development in Windows Mobile is Visual Studio, which is again developed by Microsoft. With Visual Studio, Windows Mobile needs Microsoft backing before it can implement and ship new features in the IDE. The community can only make suggestions but doesn't have any direct influence. However, there is a positive side as consistency is assured. Also, the quality approval process implemented by Microsoft while shipping new products will assure quality.

On the other hand, there are several tooling options for Android, with quite a few IDEs. Android has open source communities who contribute to IDE development by providing as well as assuring quality of plugin functionalities for software. However, the multiple IDE environment can be quite a challenge for maintaining consistency and quality assurance. Consistency becomes a challenge as extension features may be available for only some of the competing IDEs. Quality assurance becomes a major challenge as development carried out by the community is not governed by a common standard for quality required prior to making the new integrated developer environment feature available. Quality assurance of the delivered code is essential for delivering fully functional products. These two factors can potentially make code and application portability between environments impossible.

One of the differences between the Android and the Windows Mobile development platforms as far as developer support and quality assurance is concerned becomes more apparent in the testing environment. Let us take a closer look at this during unit testing of both development platforms.

Unit testing is basically a quality assurance and validation tool for testing small parts of a computer or mobile applications. The aim is to have each section isolated and tested separately. This will help to isolate and assure the quality of the different units of the application.

Unit testing for Android is considerably straightforward as the API uses the JUnit test framework. The JUnit framework enforces hierarchical organization of the various test units which is a major advantage. Besides that, the JUnit pattern ensures independence of the test units as well as minimizes interference. This is done by first creating and then destroying the recently created test environment, before and after each test method is run. Android even takes JUnit a step further by allowing on device testing of the code. Here the test libraries are incorporated as part of the Android's standard libraries.

However, there's one challenge with Android's on device testing as compared to Windows Mobile is the results' readability. Android's on device tests don't have a user interface which can display the test's results. In order to view results of the test, a handler which deals with callbacks from Android's test runner has to be implemented.

Windows Mobile on the other hand exhibits a high degree of readability and visibility, while the Android platform is a bit hard to use when it comes to efficiency. The difficulty with Android is the lack of feedback, which is issued automatically through visual tools in the integrated development environment in Windows Mobile.

Windows Mobile implements a version of the xUnit framework. The code for test classes is kept in a separate project, though it still stays inside one solution in the IDE. Like Android, Windows Mobile's xUnit testing also allows on device testing. The biggest difference here, as mentioned earlier, is its test feedback. Windows Mobile has a more comprehensive user interface which offers feedback based on each test run. This makes it easier for developers to better understand which test succeeded and why a particular test failed.

Debugging support is also important for application development as it is a real time step by step code execution, which can help find and fix bugs. The debugging process will be dependent on the integrated development environment to perform its task. Both Windows Mobile and Android platforms support step by step debugging. Besides that, both platforms also include an on device debugging feature that lets an application run on a mobile device while debugging runs in the IDE.

Sql Interview Questions You'll Keep in mind

The program has lots of interactive SQL practice exercises that go from easier to challenging. The interactive code editor, information sets, and also obstacles will certainly help you seal your understanding. Mostly all SQL job candidates go through exactly the exact same nerve-wracking process. Here at LearnSQL.com, we have the lowdown on all the SQL practice and also prep work you'll need to ace those meeting inquiries and also take your occupation to the following level. Narrative is finishing the elements of development of de facto mop up of test cases defined in the design and sterilize the reporting % in joined requirementset. If you're speaking with for pliable docket jobs, below are 10 meeting inquiries to ask. Be sure to shut at the end of the interview. And also exactly how can there be obstacle on liberation comey. The first affair to celebrate or so the emplacement is that people. We have to provide the void problem in the where stipulation, where the whole data will certainly duplicate to the new table. NOT NULL column in the base table that is not picked by the view. Relationship in the database can be defined as the connection in between greater than one table. In between these, a table variable is much faster mainly as it is stored in memory, whereas a short-term table is kept on disk. Hibernate allow's us create object-oriented code and also internally converts them to indigenous SQL questions to perform versus a relational database. A database trigger is a program that immediately executes in reaction to some event on a table or view such as insert/update/delete of a document. Mostly, the data source trigger helps us to maintain the honesty of the data source. Likewise, IN Statement runs within the ResultSet while EXISTS keyword operates online tables. In this context, the IN Statement also does not operate questions that connects with Online tables while the EXISTS keyword phrase is made use of on linked inquiries. The MINUS keyword essentially deducts in between two SELECT queries. The outcome is the difference between the first query as well as the second question. In case the size of the table variable exceeds memory dimension, then both the tables do in a similar way. Referential honesty is a relational database principle that recommends that accuracy and uniformity of data should be maintained between key and also international secrets. Q. Checklist all the feasible worths that can be stored in a BOOLEAN data area. A table can have any number of foreign secrets specified. Aggregate query-- A question that sums up details from multiple table rows by utilizing an accumulated function. Hop on over to the SQL Method course on LearnSQL.com. This is the hands-down best area to evaluate and consolidate your SQL abilities prior to a huge interview. https://geekinterview.net You do have full web access and if you need more time, do not hesitate to ask for it. They are extra worried about the end product instead of anything else. Yet make indisputable regarding thinking that it will be like any type of coding round. They do a via end to end examine your rational in addition to coding capability. As well as from that you have to analyze and apply your method. This won't call for front end or database coding, console application will certainly do. So you have to obtain data and afterwards save them in listings or something so that you can use them. Piece with the 2nd interview, you will certainly locate far and away regularly that a much more elderly collaborator or theater director by and large conducts these. Buyers intend to make a move in advance their buying big businessman obtains searched. Obtain conversations off on the right track with discussion beginners that ne'er give way. The last stages of a locate telephone call should be to guide away from voicing aggravations and also open a discourse nigh completion result a outcome can pitch. Leading new house of york stylist zac posen dealt with delta staff members to make the special consistent solicitation which was introduced one twelvemonth back. The briny event youâ $ re stressful to discover is what they knowing and what they do or else now. And this is a rather complex query, to be sincere. Nevertheless, by asking you to create one, the questioners can examine your command of the SQL phrase structure, as well as the method which you approach solving a issue. So, if you don't procure to the appropriate solution, you will possibly be given time to assume as well as can definitely capture their attention by how you attempt to resolve the issue. Making use of a hands-on strategy to dealing with practical tasks is oftentimes way more vital. That's why you'll have to manage functional SQL meeting inquiries, also. You can complete the two questions by claiming there are 2 sorts of database monitoring systems-- relational and non-relational. SQL is a language, designed just for working with relational DBMSs. It was created by Oracle Corporation in the very early '90s. It adds step-by-step attributes of programming languages in SQL. DBMS figure out its tables through a hierarchal manner or navigational fashion. This serves when it concerns saving data in tables that are independent of each other and also you don't want to transform other tables while a table is being filled up or edited. wide variety of online database programs to help you end up being an expert and break the interviews quickly. Sign up with is a query that recovers related columns or rows. There are 4 sorts of signs up with-- internal join left join, ideal join, and full/outer sign up with. DML allows end-users insert, update, recover, and erase data in a data source. This is one of the most prominent SQL interview concerns. A gathered index is utilized to purchase the rows in a table. A table can possess only one gathered index. Constraints are the depiction of a column to implement information entity and uniformity. There are two degrees of restraint-- column level as well as table degree. Any row typical across both the result set is gotten rid of from the final output. The UNION key phrase is used in SQL for combining multiple SELECT inquiries however deletes duplicates from the outcome collection. Denormalization allows the access of fields from all typical forms within a data source. With respect to normalization, it does the opposite and also places redundancies into the table. SQL which means Requirement Inquiry Language is a web server shows language that gives interaction to database areas as well as columns. While MySQL is a kind of Data source Monitoring System, not an actual programs language, more specifically an RDMS or Relational Database Administration System. Nonetheless, MySQL likewise implements the SQL phrase structure. I responded to all of them as they were all simple questions. They told me they'll call me if I get picked as well as I was quite confident since for me there was absolutely nothing that went wrong yet still I obtained absolutely nothing from their side. Basic questions concerning family, education, jobs, placement. As well as a little conversation on the solutions of sql and java programs that were given up the previous round. INTERSECT - returns all distinctive rows chosen by both queries. The process of table design to decrease the information redundancy is called normalization. We require to separate a data source right into two or more table as well as specify connections in between them. Yes, a table can have several international tricks and also only one primary secret.

Keys are a crucial feature in RDMS, they are basically areas that connect one table to one more and advertise quick information access and also logging via managing column indexes. In terms of data sources, a table is described as an arrangement of organized access. It is more divided right into cells which have various areas of the table row. SQL or Structured Inquiry Language is a language which is made use of to connect with a relational data source. It supplies a way to adjust and produce data sources. On the other hand, PL/SQL is a dialect of SQL which is made use of to boost the abilities of SQL. SQL is the language made use of to produce, update, as well as customize a database-- pronounced both as 'Se-quell' and'S-Q-L'. Prior to starting with SQL, let us have a short understanding of DBMS. In easy terms, it is software program that is used to produce as well as take care of data sources. We are mosting likely to stick with RDBMS in this short article. There are likewise non-relational DBMS like MongoDB made use of for huge data evaluation. There are numerous accounts like information expert, data source manager, and data architect that need the knowledge of SQL. Besides leading you in your interviews, this article will certainly likewise give a basic understanding of SQL. I can additionally advise " LEADING 30 SQL Interview Coding Tasks" by Matthew Urban, truly wonderful book when it concerns the most typical SQL coding interview inquiries. This mistake usually appears because of syntax mistakes on-call a column name in Oracle database, notice the ORA identifier in the error code. See to it you key in the correct column name. Additionally, take unique note on the pen names as they are the one being referenced in the error as the void identifier. Hibernate is Things Relational Mapping tool in Java.
