#Boolean data

[raintailed]

refs for a code creature named Boolean (it/its)! It is based on glitch slimes and digitarr from Slime Rancher :]

Boolean's whole thing is that normally it is a silly goober but, if stressed or agitated enough, it'll turn into its digitarr form (which is the second image). It's quite mean in that form lol

[fashion-foxy]

The tech bro inside me that makes fun of people who don't know how Ai works and the 2000s teen movie popular girl in me who passive aggressively makes fun of everyone balance out perfectly into someone who cannot watch most movies

I don't know how to code but I also don't know how to stop.

A structured way to learn JavaScript.

I came across a post on Twitter that I thought would be helpful to share with those who are struggling to find a structured way to learn Javascript on their own. Personally, I wish I had access to this information when I first started learning in January. However, I am grateful for my learning journey so far, as I have covered most topics, albeit in a less structured manner.

N/B: Not everyone learns in the same way; it's important to find what works for you. This is a guide, not a rulebook.

EASY

What is JavaScript and its role in web development?

Brief history and evolution of JavaScript.

Basic syntax and structure of JavaScript code.

Understanding variables, constants, and their declaration.

Data types: numbers, strings, boolean, and null/undefined.

Arithmetic, assignment, comparison, and logical operators.

Combining operators to create expressions.

Conditional statements (if, else if, else) for decision making.

Loops (for, while) for repetitive tasks. - Switch statements for multiple conditional cases.

MEDIUM

Defining functions, including parameters and return values.

Function scope, closures, and their practical applications.

Creating and manipulating arrays.

Working with objects, properties, and methods.

Iterating through arrays and objects.Understanding the Document Object Model (DOM).

Selecting and modifying HTML elements with JavaScript.Handling events (click, submit, etc.) with event listeners.

Using try-catch blocks to handle exceptions.

Common error types and debugging techniques.

HARD

Callback functions and their limitations.

Dealing with asynchronous operations, such as AJAX requests.

Promises for handling asynchronous operations.

Async/await for cleaner asynchronous code.

Arrow functions for concise function syntax.

Template literals for flexible string interpolation.

Destructuring for unpacking values from arrays and objects.

Spread/rest operators.

Design Patterns.

Writing unit tests with testing frameworks.

Code optimization techniques.

That's it I guess!

been a long time since I posted anything about coding, probably because I haven't been doing much of anything for a while since I had a really bad experience at my job which burned me out so bad I had to switch industries.

but I just implemented an amazing feature for my library, untwine, which is a parser generator macro enabling extremely easy parsing of any format (and it's even capable of doing context-sensitive parsing!).

look at how a boolean parser would be defined before:

this isn't so bad, but it's duplicating the string equality check, so it will check if the string is equal to "true" twice - once when it parses the pattern, and once when converting the data in the code block.

this approach also doesn't scale. in the case where you're matching weekdays, you end up needing a match statement inside your code block:

this gave me the ick for a long time because you have to repeat yourself and you have an ugly unreachable case which will trigger if you ever forget to add a case to the match statement after adding it to the pattern (which is very easy to do).

so now I've implemented a parser type which looks and acts like a match statement, allowing you to express things like that much more elegantly:

it's also extremely handy for command parsing, allowing me to express branching parsing paths that evaluate to the same type very cleanly. you can capture the values of the patterns you parse, which is perfect for grabbing arguments:

for all my 2 (± 1) followers who understand and care about parsing, you can see the full project up at https://crates.io/crates/untwine

So Solar Beta and Lunar Beta are the same AI but different personalities? The solar form seems more daring, I guess he would hug Y/N in the teddy bear suit without hesitation, right? Lol

Also happy Valentine's Day!

He's a single AI with a dual personality, yeah! It's as if you tell the AI to act differently under certain conditions (in coding, the most basic way to do this is to use some conditional/boolean structure). But they're not THAT different from each other, and they may appear to be two different AIs because they don't share memory, so Beta Solar would have different memories about you, if he ever met you

The Solar form is just a prototype, very poorly made, by the way. The idea of those who programmed him was that during this state, the Solar form wouldn't have access to the main memory but would store all the collected data (for future reports) in a separate, removable, and easily accessible storage to avoid mixing information. This way, everything would be more "organized," and the Solar form wouldn't be influenced by the Lunar form and vice versa. But this guy is a walking machine of bugs and errors; he overheats too much as if trying to emulate another OS with a low-performance CPU. Sometimes, he also has little control over his body and drops things, trips, or simply shuts down (if he doesn’t catch fire)

Edit: the idea was that the solar form could access the most recent memories of the Lunar to have some notion and context, but everyone forgot about this part hsushhshs

I like to play with the fact that, even though Beta refers to the type of radiation with that name, he's also a test project and has not yet reached his final form

Yes, Beta Solar would probably be less hesitant to hug teddy YN! ann maybe squeeze and kiss them a little, everything the Lunar form would have wanted but kept only in his thoughts lmao

Happy Valentine's Day to you and everyone reading this! <3

one finding of rotating sengen in a cave behind a waterfall is the elasticity of dcst's characters on account of they are basically video game characters. which was already obvious, but it's interesting to think about from the perspective of picking up dolls to play with rather than just passively watching the skit-laden game of snake that dcst's cast entails.

characters whose traits are their skills. sure, they have personalities, and even backstories as necessary. but their story roles are tied to their clear niches. they operate on rules and set interactions. parameters to their characterization that are like the writing equivalent of memorable, exaggerated silhouettes. they are vehicles to deliver demonstrations of science, so all the mushier nuances of their psychology (not to be confused with gen's Demonstrations Of Mentalism) are left to extrapolation.

not that they or the story of dcst itself have no Heart. dcst's writing is competent enough to include those Empathy Hooks, those Vulnerable and Relatable moments that give sufficient motivation to the characters (for being what they are in the type of storyworld that they're in). dr. stone isn't a purely mechanistic progression story in the same way that a video game isn't purely numerical and boolean variables served straight to the player.

but it is a story that is about what it's about, and by the Fandom Theory Of Gap-Filling, that means free real estate to explore narratives that are not bound to a borderline edutainment maxim of "everything is in service of showing off a facet or application of science."

(of course, that's not to say canon topic/tonal compliance isn't a factor in fanworks or even some authors' Whole Shit, but i cannot be addressing every tangential countercounterpoint or i'll be caveating in circles here.)

what i'm getting at is. there are only so many ways one can go, in the scenario of writing character-driven stories based on a source material where the extent of the ostensibly most popular character's backstory is: he's been on TV and wrote a half-assed book once. which is to say, there are so many ways one can go. the blorbo is your oyster. within reason. or not within reason. go crazy go stupid. to each their own.

and to each their own indeed. that's the fun, watching everyone's different interpretations of the same characters based on the same information. i like the way this one post frames it. studied stars in our communal observatory that is fandom.

though that's drifting out into general fandom concepts. on top of all of this basically being a long way of pointing out that these are cartoon characters from a nonsenseworld story and therefore involve some squaring the disparities when going for a different level of realism or style of character writing. which is barely a phenomenon, let alone one specific to this fandom.

but that's because this has actually been a bunch of idle musing, only short essay-like by length rather than by aiming towards any particular meaningful purpose or conclusion. :P

though if i wanted to tack on some relevance, then i might as well bring it back to the prompting topic mentioned in the first sentence and then never again:

a top question in the face of limited data for our shipping scientists is how does a notoriously unsentimental character succumb to the sentiment of romantic love?

and the answer, it turns out, is ohhh, do the people crave the gap moe. they crave it. they want to melt that boy. in whatever way that means to them, such that the result is they get to see that shaky-handed, cotton candy-handing canon soft side, but peeled open instead of rationed out into Acceptable Masculinely Stoic Intervals.

i enjoy a melting myself (i don't know if one could be a sengenner if they didn't to some degree), though i like it best when it feels earned. not because otherwise is Doing It Wrong, but because it's just more satisfying that way. but of course what feels "earned" is going to be another point of contention among All We Astronomers, and it's not something i've even necessarily identified for myself yet.

which is, again, part of the fun and what has me intrigued thinking about all this. sengen is a bouncy ball i keep throwing at the wall, and it keeps coming back to me at another angle. two characters who could fall in love in twenty subtly different equally plausible ways.

Alert

I believe I have made a mistake.

I was attempting to find out more information about AdvUript when one of my alerts went off. After the To Long Night, I decided to make an alert attached to the attention variable, that went off whenever someone observed the cube that wasn’t me. I figured it would make a good alert, and I could get a file id of my fellow coder.

I quickly ran the DataFile command on the id, and found its GPV. It was a few meters away, sitting in a cage, looking adorable.

Remington was being registered by the cube.

I looked through his data, finding much of it similar to my own. He had barely any Type 3 variables (variables that cause type 3 errors), and instead had what looked like huge Boolean lists. A Quick Look at the help files showed something that looked like a basic neural network.

The thing I was not expecting to find was an external reference to something labeled “AdvUript DrePLoSU 328AC3”. The help document requires credentials, but I was able to navigate to the actual file structure via the reference. When I tried to make a DataFile for that, I think I started Lagging?

What I mean by that is I could see my body moving, but I wasn’t. Like, I would lift my arm, and I could see it lift, but I was still feeling the keyboard? I fell unconscious for a bit, and when I woke up, the reference was gone. I still had access to Remingtons DataFile, but a bunch of values had been wiped. My notes were intact, fortunately.

The only other change I found was a new reference on my DataFile to “AdvUript SLoTEStp 93D3”.

I’m concerned.

Pleasantly Yours,

Tester

🌟 Understanding Arrays: A Beginner’s Deep Dive! 🌟

Hey Tumblr friends 👋

Today I want to break down something super important if you're getting into coding: Arrays. (Yes, those weird-looking brackets you've probably seen in code snippets? Let’s talk about them.)

So... What Exactly Is an Array? 🤔

Imagine you have a bunch of favorite songs you want to save. Instead of creating a new playlist for each song (chaotic!), you put them all into one single playlist.

That playlist? That’s what an Array is in programming! 🎶✨

An array is basically a container where you can store multiple values together under a single name.

Instead of doing this:

You can just do:

Why Are Arrays Useful? 🌈

✅ You can group related data together. ✅ You can loop through them easily. ✅ You can dynamically access or update data. ✅ You keep your code clean and organized. (No messy variables 👀)

How Do You Create an Array? ✨

Here's a simple array:

Or create an empty array first (you must specify size in C++):

Note: C++ arrays have a fixed size once declared!

How Do You Access Items in an Array? 🔎

Arrays are zero-indexed. That means the first element is at position 0.

Example:

Changing Stuff in an Array 🛠️

You can update an item like this:

Looping Through an Array 🔄

Instead of writing:

Use a loop:

Or a range-based for loop (cleaner!):

Some Cool Things You Can Do With Arrays 🚀

In C++ you don't have built-in methods like push, pop, etc. for raw arrays, but you can use vectors (dynamic arrays)! Example with vector:

Quick Tip: Arrays Can Store Anything 🤯

You can store numbers, booleans, objects (structures/classes), and even arrays inside arrays (multidimensional arrays).

Example:

Real-World Example 🌍

A To-Do list:

Output:

👏 See how clean and readable that is compared to hardcoding every single task?

🌟 Final Thoughts

Arrays are the foundation of so much you'll do in coding — from simple projects to complex apps. Master them early, and you'll thank yourself later!

🌱 Start practicing:

Make a list of your favorite movies

Your favorite foods

Songs you love

...all in an array!

stream of consciousness about the new animation vs. coding episode, as a python programmer

holy shit, my increasingly exciting reaction as i realized that yellow was writing in PYTHON. i write in python. it's the programming language that i used in school and current use in work.

i was kinda expecting a print("hello world") but that's fine

i think using python to demonstrate coding was a practical choice. it's one of the most commonly used programming languages and it's very human readable.

the episode wasn't able to cram every possible concept in programming, of course, but they got a lot of them!

fun stuff like print() not outputting anything and typecasting between string values and integer values!!

string manipulation

booleans

little things like for-loops and while-loops for iterating over a string or list. and indexing! yay :D

* iterable input :D (the *bomb that got thrown at yellow)

and then they started importing libraries! i've never seen the turtle library but it seems like it draws vectors based on the angle you input into a function

the gun list ran out of "bullets" because it kept removing them from the list gun.pop()

AND THEN THE DATA VISUALIZATION. matplotlib!! numpy!!!! my beloved!!!!!!!! i work in data so this!!!! this!!!!! somehow really validating to me to see my favorite animated web series play with data. i think it's also a nice touch that the blue on the bars appear to be the matplotlib default blue. the plot formatting is accurate too!!!

haven't really used pygame either but making shapes and making them move based on arrow key input makes sense

i recall that yellow isn't the physically strongest, but it's cool to see them move around in space and i'm focusing on how they move and figure out the world.

nuke?!

and back to syntax error and then commenting it out # made it go away

cool nuke text motion graphics too :D (i don't think i make that motion in python, personally)

and then yellow cranks it to 100,000 to make a neural network in pytorch. this gets into nlp (tokenizers and other modeling)

a CLASS? we touch on some object oriented programming here but we just see the __init__ function so not the full concept is demonstrated here.

OH! the "hello world" got broken down into tokens. that's why we see the "hello world" string turn into numbers and then... bits (the 0s and 1s)? the strings are tokenized/turned into values that the model can interpret. it's trying to understand written human language

and then an LSTM?! (long short-term memory)

something something feed-forward neural network

model training (hence the epochs and increasing accuracy)

honestly, the scrolling through the code goes so fast, i had to do a second look through (i'm also not very deeply versed in implementing neural networks but i have learned about them in school)

and all of this to send "hello world" to an AI(?) recreation of the exploded laptop

not too bad for a macbook user lol

i'm just kidding, a major of people used macs in my classes

things i wanna do next since im so hyped

i haven't drawn for the fandom in a long time, but i feel a little motivated to draw my design of yellow again. i don't recall the episode using object oriented programming, but i kinda want to make a very simple example where the code is an initialization of a stick figure object and the instances are each of the color gang.

it wouldn't be full blown AI, but it's just me writing in everyone's personality traits and colors into a function, essentially since each stick figure is an individual program.

[prof-lemon]

((OOC: switching to plain text for readability and since providing a plain text translation of the entire thing would have been.... way too long.))

JavaScript

Introduction to JavaScript Basics

JavaScript (JS) is one of the core technologies of the web, alongside HTML and CSS. It is a powerful, lightweight, and versatile scripting language that allows developers to create interactive and dynamic content on web pages. Whether you're a beginner or someone brushing up on their knowledge, understanding the basics of JavaScript is essential for modern web development.

What is JavaScript?

JavaScript is a client-side scripting language, meaning it is primarily executed in the user's web browser without needing a server. It's also used as a server-side language through platforms like Node.js. JavaScript enables developers to implement complex features such as real-time updates, interactive forms, and animations.

Key Features of JavaScript

Interactivity: JavaScript adds life to web pages by enabling interactivity, such as buttons, forms, and animations.

Versatility: It works on almost every platform and is compatible with most modern browsers.

Asynchronous Programming: JavaScript handles tasks like fetching data from servers without reloading a web page.

Extensive Libraries and Frameworks: Frameworks like React, Angular, and Vue make it even more powerful.

JavaScript Basics You Should Know

1. Variables

Variables store data that can be used and manipulated later. In JavaScript, there are three ways to declare variables:

var (old way, avoid using in modern JS)

let (block-scoped variable)

const (constant variable that cannot be reassigned)

Example:

javascript

Copy code

let name = "John"; // can be reassigned const age = 25; // cannot be reassigned

2. Data Types

JavaScript supports several data types:

String: Text data (e.g., "Hello, World!")

Number: Numeric values (e.g., 123, 3.14)

Boolean: True or false values (true, false)

Object: Complex data (e.g., { key: "value" })

Array: List of items (e.g., [1, 2, 3])

Undefined: A variable declared but not assigned a value

Null: Intentional absence of value

Example:

javascript

Copy code

let isLoggedIn = true; // Boolean let items = ["Apple", "Banana", "Cherry"]; // Array

3. Functions

Functions are reusable blocks of code that perform a task.

Example:

javascript

Copy code

function greet(name) { return `Hello, ${name}!`; } console.log(greet("Alice")); // Output: Hello, Alice!

4. Control Structures

JavaScript supports conditions and loops to control program flow:

If-Else Statements:

javascript

Copy code

if (age > 18) { console.log("You are an adult."); } else { console.log("You are a minor."); }

Loops:

javascript

Copy code

for (let i = 0; i < 5; i++) { console.log(i); }

5. DOM Manipulation

JavaScript can interact with and modify the Document Object Model (DOM), which represents the structure of a web page.

Example:

javascript

Copy code

document.getElementById("btn").addEventListener("click", () => { alert("Button clicked!"); });

mysite

Conclusion

JavaScript is an essential skill for web developers. By mastering its basics, you can create dynamic and interactive websites that provide an excellent user experience. As you progress, you can explore advanced concepts like asynchronous programming, object-oriented design, and popular JavaScript frameworks. Keep practicing, and you'll unlock the true power of JavaScript!

One of the main or fundamental characteristics of any programming language is Functions, but why? Because functions help us maintain order, organization, and also greatly assist in inevitable future maintenance of our code. All the dynamics of programs are carried out through functions.

What are functions ?

But what are functions? Functions are generally small pieces or parts of code that exist outside the main scope of the program, meaning they are code snippets that are called by the function's identifier (name) and also by its return type for that functionality. Therefore, they are responsible for performing a specific task in our program, such as processing a piece of data or a certain number of data that other parts of the program do not handle.

Imagine a program that requests 3 grades to calculate the student's average. Although the program is simple, you can break it down or divide it into parts for future modifications.

All functions must be specified by a type, meaning the type of data they will return. Return types in C++ basically come down to: integer, float, boolean, and void, with the latter not returning any value.

What Not to Do - Typical Errors

Do not give functions names that are not clear about their functionality. This makes the code harder to read and, consequently, more time-consuming when it comes to maintenance or corrections.

In C++, there is an order that functions must follow to avoid errors during compilation.

Notice that now the program's organization has changed. 1) Incredibly, this will result in a compilation error. Why? Because the C++ compiler does not find the function mediaFunction() - now you might be thinking, "But why, since mediaFunction() is there in main()?" For the C++ compiler, there is an order.

But how do you solve this problem in C++? There are 2 options: a) You declare the function at the beginning of the code, or b) you place the function before main. However, there is a problem with this last detail. What if another function A calls function B, and function B calls function A?

We would have the same problem again. Therefore, what must be done is to declare a prototype of the function at the beginning.

Conclusion:

From the little shown here about functions, it is clear that this is a fundamental skill for anyone aspiring to be a good programmer. I tried not to go into too many details because the intention is not to be a course on how to create, but at least to make it a little clear about the fundamental aspect of functions within any code.
