Omg are you in school to become a librarian? I’ve been considering doing the same, but I’m a little put off by how long the process is 😭 from when I looked it up it said you need a masters. I’m curious what your experience has been so far if you don’t mind my asking?

You do need a masters to be a librarian, which is typically a two year commitment (if you’re full time), I’ll be getting mine in 2.5ish bc i started part time and am transitioning to full time this fall. My MLIS is with an archival studies concentration + digital libraries focus and I find it incredibly rewarding honestly, i got my BA in Public History and worked in Digital Humanities for two years so it was a super natural transition for me. lots of ppl start their MLIS with 0 experience in libraries though and the intro classes are frequently very beginner friendly.

i’m getting my degree online and have evening classes twice or three times a week (one meeting per week per class). I find that library programs are deeply queer even at my deep south institution and are super flexible to your interests and goals. + scholarships are typically easier to get than you think. open up your heart to a beautiful MLIS program

i need more mutuals who are into coding and engineering!! more info under the cut!!

I planned to become an electrical engineer like my stepdad but then I decided to change my path to programming. I'm currently studying at technikum (<- wikipedia link so I don't have to explain the whole polish learning system), programmer major.

this year I have exams from web development (10th Jan - theory, 16th Jan - practical exams) and next year I have exams from App development (both mobile and desktop).

I know C family languages, Java, Python and those ones I am currently using. I also know a bit of Kotlin and I think I will continue learning it.

For web dev I know HTML and CSS ofc but also PHP and JS.

Planning on learning more languages I can use for App and operating system development as well as just to know them cause I want to after this year's exams!

my learning list:

Lua (I heard it's easy but I can't really get myself to read anything about this atm idk why)

Ruby

Assembly

Rust

As for electrical engineering I don't know much tbh but I would like to learn! I just used CAD programs for technical drawings (dad taught me some basic things when I was still thinking about going his path) helped my dad fix things on his Solar farm, houses of our neighbors and I made a few very simple circuits for fun a few years ago. Now I'm mostly focused on programming but since I learned most of the things I need for exams I have more time to do whatever I want now!

I'd like to get to know more people so I can share and mostly learn new things since even though I'm coding for years I consider myself a beginner and I am a total beginner when it comes to electrical engineering.

I'm willing to be friends or at least mutuals with anyone who codes or makes websites or is in STEM! no matter what your specialty/interest is exactly and no matter if you are a total beginner or a professional ^__^

I'd also like to have some mutuals who are into old web development and retro computing!!!!!!!!

edit: I forgot but I'm also interested in physics and quantum physics

SQL Fundamentals #1: SQL Data Definition

Last year in college , I had the opportunity to dive deep into SQL. The course was made even more exciting by an amazing instructor . Fast forward to today, and I regularly use SQL in my backend development work with PHP. Today, I felt the need to refresh my SQL knowledge a bit, and that's why I've put together three posts aimed at helping beginners grasp the fundamentals of SQL.

Understanding Relational Databases

Let's Begin with the Basics: What Is a Database?

Simply put, a database is like a digital warehouse where you store large amounts of data. When you work on projects that involve data, you need a place to keep that data organized and accessible, and that's where databases come into play.

Exploring Different Types of Databases

When it comes to databases, there are two primary types to consider: relational and non-relational.

Relational Databases: Structured Like Tables

Think of a relational database as a collection of neatly organized tables, somewhat like rows and columns in an Excel spreadsheet. Each table represents a specific type of information, and these tables are interconnected through shared attributes. It's similar to a well-organized library catalog where you can find books by author, title, or genre.

Key Points:

Tables with rows and columns.

Data is neatly structured, much like a library catalog.

You use a structured query language (SQL) to interact with it.

Ideal for handling structured data with complex relationships.

Non-Relational Databases: Flexibility in Containers

Now, imagine a non-relational database as a collection of flexible containers, more like bins or boxes. Each container holds data, but they don't have to adhere to a fixed format. It's like managing a diverse collection of items in various boxes without strict rules. This flexibility is incredibly useful when dealing with unstructured or rapidly changing data, like social media posts or sensor readings.

Key Points:

Data can be stored in diverse formats.

There's no rigid structure; adaptability is the name of the game.

Non-relational databases (often called NoSQL databases) are commonly used.

Ideal for handling unstructured or dynamic data.

Now, Let's Dive into SQL:

SQL is a :

Data Definition language ( what todays post is all about )

Data Manipulation language

Data Query language

Task: Building and Interacting with a Bookstore Database

Setting Up the Database

Our first step in creating a bookstore database is to establish it. You can achieve this with a straightforward SQL command:

CREATE DATABASE bookstoreDB;

SQL Data Definition

As the name suggests, this step is all about defining your tables. By the end of this phase, your database and the tables within it are created and ready for action.

1 - Introducing the 'Books' Table

A bookstore is all about its collection of books, so our 'bookstoreDB' needs a place to store them. We'll call this place the 'books' table. Here's how you create it:

CREATE TABLE books ( -- Don't worry, we'll fill this in soon! );

Now, each book has its own set of unique details, including titles, authors, genres, publication years, and prices. These details will become the columns in our 'books' table, ensuring that every book can be fully described.

Now that we have the plan, let's create our 'books' table with all these attributes:

CREATE TABLE books ( title VARCHAR(40), author VARCHAR(40), genre VARCHAR(40), publishedYear DATE, price INT(10) );

With this structure in place, our bookstore database is ready to house a world of books.

2 - Making Changes to the Table

Sometimes, you might need to modify a table you've created in your database. Whether it's correcting an error during table creation, renaming the table, or adding/removing columns, these changes are made using the 'ALTER TABLE' command.

For instance, if you want to rename your 'books' table:

ALTER TABLE books RENAME TO books_table;

If you want to add a new column:

ALTER TABLE books ADD COLUMN description VARCHAR(100);

Or, if you need to delete a column:

ALTER TABLE books DROP COLUMN title;

3 - Dropping the Table

Finally, if you ever want to remove a table you've created in your database, you can do so using the 'DROP TABLE' command:

DROP TABLE books;

To keep this post concise, our next post will delve into the second step, which involves data manipulation. Once our bookstore database is up and running with its tables, we'll explore how to modify and enrich it with new information and data. Stay tuned ...

USEFUL TIPS FOR ANYONE USING NEOCITIES

So, I saw this super awesome post called BEGINNERS GUIDE TO BLUESKY and it more or less inspired me to make a post of my own pertaining to the the likes of Neocities.

What is Neocities?

Long story short, it is an open-source web hosting service that is both F2U (1 GB storage/200 GB bandwidth) and P2U (50 GB storage/3000 GB bandwidth). It's kinda sorta a spiritual successor to the now defunct GeoCities.

Why Use Neocities?

HELPFUL LINKS

Neocities has a full on Tutorials Page to help people wanting to learning how to code. Though I will say that I'm a bit surprised they don't have W3 Schools on there.

CREATIVE FREEDOM

If you Browse on Neocities, you will see how vastly different all of the websites look. That being said, you have an enormous amount of creative freedom when it comes to making your website. You can build it from scratch or look up some pre-made templates from websites such as templatemo, HTML5 Templates, TEMPLATED, template4all, and many more.

Now it is important to note that Neocities doesn't allow certain things such as jQuery, PHP, Python, SQL, etc. In fact, the only things allowed on Neocities are HTML, CSS, and JavaScript! Though I do think it is important to note that you can turn your website into a blog using Zonelets, have a Guestbook/Comments Section with Guestbooks, embed your Bluesky feed with Embed Bsky, embed your Twitter/X feed with Twitter Publish, and much more!

What Do People Use Neocities For?

Some people use it for blogging & portfolio & educational purposes. Some people use it to share their writings & artwork & music. Some people use it to help people with finding neat things. Some people use it for shits and giggles. There are legitimately a number of reasons people use it and you know what? That's 100% a-okay!

Are Any Programs Required To Use Neocities?

Technically, no. The reason I say this is because Neocities has a built-in HTML Editor. However, I don't like using it unless if I absolutely have to (which is next to never). Instead, I use Brackets. It's very user-friendly and it legit lets you know if there's a goof somewhere in your code. Legit 10 out of 10 recommend. Though I will say that some people use Notepad++.
