SQL GitHub Repositories

I’ve recently been looking up more SQL resources and found some repositories on GitHub that are helpful with learning SQL, so I thought I’d share some here!

Guides:

s-shemee SQL 101: A beginner’s guide to SQL database programming! It offers tutorials, exercises, and resources to help practice SQL

nightFuryman SQL in 30 Days: The fundamentals of SQL with information on how to set up a SQL database from scratch as well as basic SQL commands

Projects:

iweld SQL Dictionary Challenge: A SQL project inspired by a comment on this reddit thread https://www.reddit.com/r/SQL/comments/g4ct1l/what_are_some_good_resources_to_practice_sql/. This project consists of creating a single file with a column of randomly selected words from the dictionary. For this column, you can answer the various questions listed in the repository through SQL queries, or develop your own questions to answer as well.

DevMountain SQL 1 Afternoon: A SQL project where you practice inserting querying data using SQL. This project consists of creating various tables and querying data through this online tool created by DevMountain, found at this link https://postgres.devmountain.com/.

DevMountain SQL 2 Afternoon: The second part of DevMountain’s SQL project. This project involves intermediate queries such as “practice joins, nested queries, updating rows, group by, distinct, and foreign key”.

Navigating MAXDOP in SQL Server 2022: Best Practices for Multi-Database Environments

In the realm of SQL Server management, one of the pivotal settings that database administrators must judiciously configure is the Maximum Degree of Parallelism (MAXDOP). This setting determines the number of processors that SQL Server can use for the execution of a query. Proper configuration of MAXDOP is essential, especially in environments with multiple databases and a limited number of CPU…

[komaedalovemail]

komaedas have you tried straw.page?

(i hope you don't mind if i make a big ollllle webdev post off this!)

i have never tried straw.page but it looks similar to carrd and other WYSIWYG editors (which is unappealing to me, since i know html/css/js and want full control of the code. and can't hide secrets in code comments.....)

my 2 cents as a web designer is if you're looking to learn web design or host long-term web projects, WYSIWYG editors suck doodooass. you don't learn the basics of coding, someone else does it for you! however, if you're just looking to quickly host images, links to your other social medias, write text entries/blogposts, WYSIWYG can be nice.

toyhouse, tumblr, deviantart, a lot of sites implement WYSIWYG for their post editors as well, but then you can run into issues relying on their main site features for things like the search system, user profiles, comments, etc. but it can be nice to just login to your account and host your information in one place, especially on a platform that's geared towards that specific type of information. (toyhouse is a better example of this, since you have a lot of control of how your profile/character pages look, even without a premium account) carrd can be nice if you just want to say "here's where to find me on other sites," for example. but sometimes you want a full website!

---------------------------------------

neocities hosting

currently, i host my website on neocities, but i would say the web2.0sphere has sucked some doodooass right now and i'm fiending for something better than it. it's a static web host, e.g. you can upload text, image, audio, and client-side (mostly javascript and css) files, and html pages. for the past few years, neocities' servers have gotten slower and slower and had total blackouts with no notices about why it's happening... and i'm realizing they host a lot of crypto sites that have crypto miners that eat up a ton of server resources. i don't think they're doing anything to limit bot or crypto mining activity and regular users are taking a hit.

↑ page 1 on neocitie's most viewed sites we find this site. this site has a crypto miner on it, just so i'm not making up claims without proof here. there is also a very populated #crypto tag on neocities (has porn in it tho so be warned...).

---------------------------------------

dynamic/server-side web hosting

$5/mo for neocities premium seems cheap until you realize... The Beautiful World of Server-side Web Hosting!

client-side AKA static web hosting (neocities, geocities) means you can upload images, audio, video, and other files that do not interact with the server where the website is hosted, like html, css, and javascript. the user reading your webpage does not send any information to the server like a username, password, their favourite colour, etc. - any variables handled by scripts like javascript will be forgotten when the page is reloaded, since there's no way to save it to the web server. server-side AKA dynamic web hosting can utilize any script like php, ruby, python, or perl, and has an SQL database to store variables like the aforementioned that would have previously had nowhere to be stored.

there are many places in 2024 you can host a website for free, including: infinityfree (i use this for my test websites :B has tons of subdomains to choose from) [unlimited sites, 5gb/unlimited storage], googiehost [1 site, 1gb/1mb storage], freehostia [5 sites/1 database, 250mb storage], freehosting [1 site, 10gb/unlimited storage]

if you want more features like extra websites, more storage, a dedicated e-mail, PHP configuration, etc, you can look into paying a lil shmoney for web hosting: there's hostinger (this is my promocode so i get. shmoney. if you. um. 🗿🗿🗿) [$2.40-3.99+/mo, 100 sites/300 databases, 100gb storage, 25k visits/mo], a2hosting [$1.75-12.99+/mo, 1 site/5 databases, 10gb/1gb storage], and cloudways [$10-11+/mo, 25gb/1gb]. i'm seeing people say to stay away from godaddy and hostgator. before you purchase a plan, look up coupons, too! (i usually renew my plan ahead of time when hostinger runs good sales/coupons LOL)

here's a big webhost comparison chart from r/HostingHostel circa jan 2024.

---------------------------------------

domain names

most of the free website hosts will give you a subdomain like yoursite.has-a-cool-website-69.org, and usually paid hosts expect you to bring your own domain name. i got my domain on namecheap (enticing registration prices, mid renewal prices), there's also porkbun, cloudflare, namesilo, and amazon route 53. don't use godaddy or squarespace. make sure you double check the promo price vs. the actual renewal price and don't get charged $120/mo when you thought it was $4/mo during a promo, certain TLDs (endings like .com, .org, .cool, etc) cost more and have a base price (.car costs $2,300?!?). look up coupons before you purchase these as well!

namecheap and porkbun offer something called "handshake domains," DO NOT BUY THESE. 🤣🤣🤣 they're usually cheaper and offer more appealing, hyper-specific endings like .iloveu, .8888, .catgirl, .dookie, .gethigh, .♥, .❣, and .✟. I WISH WE COULD HAVE THEM but they're literally unusable. in order to access a page using a handshake domain, you need to download a handshake resolver. every time the user connects to the site, they have to provide proof of work. aside from it being incredibly wasteful, you LITERALLY cannot just type in the URL and go to your own website, you need to download a handshake resolver, meaning everyday internet users cannot access your site.

---------------------------------------

hosting a static site on a dynamic webhost

you can host a static (html/css/js only) website on a dynamic web server without having to learn PHP and SQL! if you're coming from somewhere like neocities, the only thing you need to do is configure your website's properties. your hosting service will probably have tutorials to follow for this, and possibly already did some steps for you. you need to point the nameserver to your domain, install an SSL certificate, and connect to your site using FTP for future uploads. FTP is a faster, alternative way to upload files to your website instead of your webhost's file upload system; programs like WinSCP or FileZilla can upload using FTP for you.

if you wanna learn PHP and SQL and really get into webdev, i wrote a forum post at Mysidia Adoptables here, tho it's sorted geared at the mysidia script library itself (Mysidia Adoptables is a free virtual pet site script, tiny community. go check it out!)

---------------------------------------

file storage & backups

a problem i have run into a lot in my past like, 20 years of internet usage (/OLD) is that a site that is free, has a small community, and maybe sounds too good/cheap to be true, has a higher chance of going under. sometimes this happens to bigger sites like tinypic, photobucket, and imageshack, but for every site like that, there's like a million of baby sites that died with people's files. host your files/websites on a well-known site, or at least back it up and expect it to go under!

i used to host my images on something called "imgjoe" during the tinypic/imageshack era, it lasted about 3 years, and i lost everything hosted on there. more recently, komaedalovemail had its webpages hosted here on tumblr, and tumblr changed its UI so custom pages don't allow javascript, which prevented any new pages from being edited/added. another test site i made a couple years ago on hostinger's site called 000webhost went under/became a part of hostinger's paid-only plans, so i had to look very quickly for a new host or i'd lose my test site.

if you're broke like me, looking into physical file storage can be expensive. anything related to computers has gone through baaaaad inflation due to crypto, which again, I Freaquing Hate, and is killing mother nature. STOP MINING CRYPTO this is gonna be you in 1 year

...um i digress. ANYWAYS, you can archive your websites, which'll save your static assets on The Internet Archive (which could use your lovely donations right now btw), and/or archive.today (also taking donations). having a webhost service with lots of storage and automatic backups can be nice if you're worried about file loss or corruption, or just don't have enough storage on your computer at home!

if you're buying physical storage, be it hard drive, solid state drive, USB stick, whatever... get an actual brand like Western Digital or Seagate and don't fall for those cheap ones on Amazon that claim to have 8,000GB for $40 or you're going to spend 13 days in windows command prompt trying to repair the disk and thenthe power is gong to go out in your shit ass neighvborhood and you have to run it tagain and then Windows 10 tryes to update and itresets the /chkdsk agin while you're awayfrom town nad you're goig to start crytypting and kts just hnot going tot br the same aever agai nikt jus not ggiog to be the saeme

---------------------------------------

further webhosting options

there are other Advanced options when it comes to web hosting. for example, you can physically own and run your own webserver, e.g. with a computer or a raspberry pi. r/selfhosted might be a good place if you're looking into that!

if you know or are learning PHP, SQL, and other server-side languages, you can host a webserver on your computer using something like XAMPP (Apache, MariaDB, PHP, & Perl) with minimal storage space (the latest version takes up a little under 1gb on my computer rn). then, you can test your website without needing an internet connection or worrying about finding a hosting plan that can support your project until you've set everything up!

there's also many PHP frameworks which can be useful for beginners and wizards of the web alike. WordPress is one which you're no doubt familiar with for creating blog posts, and Bluehost is a decent hosting service tailored to WordPress specifically. there's full frameworks like Laravel, CakePHP, and Slim, which will usually handle security, user authentication, web routing, and database interactions that you can build off of. Laravel in particular is noob-friendly imo, and is used by a large populace, and it has many tutorials, example sites built with it, and specific app frameworks.

---------------------------------------

addendum: storing sensitive data

if you decide to host a server-side website, you'll most likely have a login/out functionality (user authentication), and have to store things like usernames, passwords, and e-mails. PLEASE don't launch your website until you're sure your site security is up to snuff!

when trying to check if your data is hackable... It's time to get into the Mind of a Hacker. OWASP has some good cheat sheets that list some of the bigger security concerns and how to mitigate them as a site owner, and you can look up filtered security issues on the Exploit Database.

this is kind of its own topic if you're coding a PHP website from scratch; most frameworks securely store sensitive data for you already. if you're writing your own PHP framework, refer to php.net's security articles and this guide on writing an .htaccess file.

---------------------------------------

but. i be on that phone... :(

ok one thing i see about straw.page that seems nice is that it advertises the ability to make webpages from your phone. WYSIWYG editors in general are more capable of this. i only started looking into this yesterday, but there ARE source code editor apps for mobile devices! if you have a webhosting plan, you can download/upload assets/code from your phone and whatnot and code on the go. i downloaded Runecode for iphone. it might suck ass to keep typing those brackets.... we'll see..... but sometimes you're stuck in the car and you're like damn i wanna code my site GRRRR I WANNA CODE MY SITE!!!

↑ code written in Runecode, then uploaded to Hostinger. Runecode didn't tell me i forgot a semicolon but Hostinger did... i guess you can code from your webhost's file uploader on mobile but i don't trust them since they tend not to autosave or prompt you before closing, and if the wifi dies idk what happens to your code.

---------------------------------------

ANYWAYS! HAPPY WEBSITE BUILDING~! HOPE THIS HELPS~!~!~!

[mikotos-nape-nibbler]

if i'm being honest i don't really give a shit about the discourse of whether 09 is good or bad DID rep nor do i give a shit about how his DID manifests. i find that what makes him interesting isn't a label for a set of symptoms but rather his expression of those symptoms cultivated by the world he was raised in and how he responds or continues those behaviours. it's honestly more interesting to analyze the overarching systems in society that assisted in developing Mikoto Kayano into a murderer.

how different would he be if Japanese society were more open about emotions and struggles? how different would he be if he were receiving mental health treatment? would he still become a murderer and, if so, what made those mental health treatments ineffective? if he had been hired at another japanese company that didn't follow black company practices, would he still have become a murderer? if so, why? what were the factors that made an average, young adult become a murderer? so on so forth.

honestly the fetish this fandom has on his dissociated self that gives the illusion of multiplicity — when, in reality, he's a singular whole that is fragmented; cracks lined with dissociative barriers, chiseled by continuous stress — detracts from the complexity of his character and writing, flanderizing him into a prop of DID that the fandom puppets into theatrics of stigmatization that same fans claim to "educate" against when, in truth, spout blasé hearsays encrypted with a DIDcore-lese that does nothing for communicating information about the disorder and, instead, excludes and dissuades the general population that that supposed "education" is directed towards.

"Mikoto's a system from the interactive music project MILGRAM. His alter, 'John', murdered a bunch of people on the train."

so there's a program called "Mikoto" and you named the SQL table "John" with the ALTER command that somehow murdered a bunch of people. did the train running the Mikoto program malfunction because of some zero day error with the John table?

"'He has Dissociative Identity Disorder. John's a protector and Mikoto's the host."

so is this Mikoto guy some vessel or something for some supernatural ouija board summon and the John guy is like the familiar or bodyguard summoned? is their character just that? a job and occupation? that sounds boring. and what do those jobs have to do with a disorder on dissociation? are you talking about something like "occupation disorder" or "stuck-in-their-work-self disorder"? or is this some DnD homebrew class type?

what purpose does inaccessible language have if you're trying to educate the average person who isn't familiar with those online community terms that aren't even universal terms in literature nor research? and how are these terms even relevant to discussing Mikoto's character when the concepts it supposedly encompasses aren't universal nor applicable to all possible subjective presentations that a human brain can develop? and yet the fandom, and much of the online mental disorder community, treats those sociolect terms as an axiom — a universal truth, universal terms — and the lack of adherence to that speech is seen as wrong or sin.

"[insert link to some website claiming to have info on DID] is a good website if you wanna read up on what DID is!!"

and then that supposed resource uses highly specialized, nonuniversal, sociolect terms that is jargon to those who are only familiar with layman terms which makes the "information" — if it even is faithfully derived from research — seem like further jargon rather than a comprehensible source for educating.

applying this to Mikoto's character, those who aren't already acquainted with how he's spoken about likely view discussions or comments on him as indecipherable jargon thus it must mean Mikoto's character is just jargon thus not well-written or boring because according to the bubble of jargon people describe this guy with: Mikoto Kayano = computer program system + dnd classes or some chuunibyou alter ego personality savior complex + party hoster or vessel for some supernatural thing + mechanical switch that states 0 or 1 + going through some mitosis split

how does any of that relate to dissociation? people have made DID symptoms so convoluted, yet structured that convolutedness through terms and expressions that sound like some Gary Sue Ebony Dementia Darkness Raven trope that completely detracts from the fact that it's a dissociation disorder rather than a roleplay character form.

have people even considered the fact that if Mikoto had never been imprisoned, he, nor anyone, would even know he has DID— if he even counts as having DID? if how his brain works regarding how he handles stress doesn't impact his life negatively- even if he has all the symptoms of DID if how his brain works regarding how he handles stress doesn't cause disorder for him, he wouldn't have dissociative identity disorder.

the less people view Mikoto as the "alters guy", the more complex understandings can be gathered and discussed within the fandom. the more people view Mikoto as the "average, normal guy who committed a murder, but why? what caused an average, hardworking guy to commit the most grievous sin of murder?", the better the range of insight and curiosity into what shapes a person and the factors in their world — a reflection of our present reality — at play which interact and weave with one another to shape and respond to its members; the opposite of cutting off the fluidity and interwovenness Mikoto has with people and environments outside of his self that people constrain him to, that prison cell of a single label characteristic: "DID".

conclusion: for the love of torch novelgram, let's talk about Mikoto Kayano like the multifaceted, complex, shaped-by-the-socioeconomic-stratae-of-the-world-he-is-part-of-and-interacts-with well-written character he is.

The next rule we created was named “../”, and upon deleting that rule, the entire test SQL Server was also suddenly deleted, and we found ourselves in need of a new test server! The cause of the deletion of our test server can be found in the URL to which the DELETE request is sent. The URL the DELETE request was sent to is:  /subscriptions/<subscriptionId>/resourceGroups/<rg>/providers/Microsoft.Sql/servers/test-4ad9a/firewallRules/../?api-version=2021-11-0. The firewall rule name “../” within the URL is treated as if it refers to the parent directory and to the SQL Server itself, which leads to the entire server being deleted.

With a little effort, it’s possible to create a rule that deletes any resource in the Azure tenant with the following name: ../../../../../../../<theResourceURL>?api-version=<relevant_version>#”.

What is Lead Generation? A Complete Guide for Beginners in 2025

In the ever-evolving world of digital marketing and sales, lead generation remains a foundational strategy for business growth. Whether you’re running a small startup or a large enterprise, understanding what lead generation is—and how to do it effectively—can make or break your customer acquisition efforts.

In this post, we’ll break down what lead generation means, how it works, why it’s important in 2025, and how you can start implementing a successful lead generation strategy today.

What is Lead Generation?

Lead generation is the process of attracting and converting strangers into someone who has indicated interest in your product or service. These individuals are called "leads" and are typically the first step in the sales funnel.

A lead can be anyone who has shared their contact information with your business—whether by filling out a form, subscribing to a newsletter, downloading an eBook, or booking a demo.

The goal of lead generation is simple: build a pipeline of potential customers and nurture them into becoming paying clients.

Why Lead Generation is Crucial in 2025

With buyers becoming more informed and self-directed, the way businesses generate leads has shifted significantly. According to Demand Gen Report (source), 71% of B2B buyers start their journey with a generic search. This makes it more important than ever for businesses to have a strong online presence and provide value from the very first interaction.

Here’s why lead generation is essential in today’s landscape:

It drives business growth: Without leads, you have no sales. And without sales, you have no business.

It builds relationships: Lead generation introduces people to your brand in a helpful, non-intrusive way.

It improves ROI: Targeted lead gen strategies ensure you’re attracting the right audience, not wasting resources.

It supports long-term success: A consistent lead pipeline means predictable revenue and scalable growth.

Types of Leads

Not all leads are the same. Understanding the different types can help you tailor your messaging and approach.

1. Marketing Qualified Lead (MQL)

Someone who has shown interest through content interaction but isn’t ready to buy yet.

2. Sales Qualified Lead (SQL)

A lead who has taken action suggesting they’re ready to talk to your sales team (like booking a call).

3. Product Qualified Lead (PQL)

Typically relevant for SaaS—someone who has used your product (like a free trial) and shows buying intent.

How Lead Generation Works

The lead generation process usually includes these key steps:

1. Attract Visitors

Use SEO, social media, content marketing, and paid ads to bring people to your website or landing pages.

2. Offer Value

Create lead magnets like guides, webinars, checklists, or free tools that your target audience wants.

3. Capture Information

Use forms, chatbots, or popups to collect user details in exchange for your lead magnet.

4. Nurture and Convert

Send follow-up emails, offer more content, or schedule calls to move leads further down the funnel.

Watch: What is Lead Generation?

📹 This beginner-friendly YouTube video explains it well: "7 Keys to Lead Generation & Sales Prospecting for Business Development and B2B Sales"

Popular Lead Generation Strategies in 2025

✍️ Content Marketing

Publishing helpful blog posts, whitepapers, or videos to attract and educate potential customers.

🔍 Search Engine Optimization (SEO)

Optimizing your site and content to rank high on Google so your target audience can find you.

📧 Email Marketing

Sending personalized, value-packed messages to nurture leads and keep them engaged.

💼 LinkedIn Outreach

Great for B2B businesses—use it to connect with decision-makers and share valuable resources.

📣 Paid Advertising

Run targeted ads on Google, Facebook, or LinkedIn to bring traffic directly to high-converting landing pages.

Tools to Help with Lead Generation

Here are some must-have tools to streamline your lead generation efforts:

HubSpot – CRM and marketing automation for capturing and nurturing leads.

Mailchimp – For sending and automating email campaigns.

OptinMonster – Great for creating popups and opt-in forms.

SEMrush – For keyword research and SEO optimization.

LinkedIn Sales Navigator – Ideal for identifying and connecting with B2B leads.

How Businesses Use Lead Generation Services

Many companies choose to outsource their efforts to experts who specialize in attracting and converting high-quality leads. These lead generation services offer tailored strategies that align with your industry, audience, and growth goals—saving time while maximizing ROI.

Final Thoughts

Lead generation is the lifeblood of any successful business. Whether you’re a marketer trying to fill your sales funnel or an entrepreneur looking to grow your client base, understanding how to attract and convert leads is essential.

By combining valuable content, smart targeting, and nurturing tools, you can build a lead gen system that works for you 24/7. In 2025, the businesses that thrive will be the ones that focus not just on selling—but on providing value from the very first click.
