❄️☃️The SDV Girlies in their winter garb!☃️❄️

One side how i interpreted their lil avatars and then the other side is just me playing dress up lmao.

“Bois when?” Dunno. 🤷🏽‍♀️ I will if anyone donates screenshots.

BRB gonna invent hypercube C

It's a time-agnostic programming language

You can run code last week

[kattersz]

the protOS gossips

i love protos and especially heart can you guess I really like heart protos plese beleive me she is the most stylized there too look at their little wings aw look look heart protos

This is not the subject anyways support protagonist object show on kickstarter and read it !!! (This is a threat) ❤️

No idea where all y'all came from, but hi??? Wow. Also darn I missed getting a screenshot of exactly 100 :c

UHHHHHHH Ive barely been active on here for like a few weeks and Ive alr met so many new people 👀

[squaridot]

that's not what i meant by "brown pants" pinterest -_-

[edenlyte]

my tl is such a weird mash of pwhl/hating on Britta curl, whatever is happening in the ecf tonight, and also cat photos and all I can say is ahhhhh playoffs

[scarletcomet]

someone please tell me that getting a C in analysis of algorithms isn't the end of the world

Got jumpscared by my own full legal name showing up in my email notifications bc I forgot I emailed my code to myself today just in case my VM ends up stopping working again (I got nervous & didn't wanna lose my progress lol)

Goldfish level memory retention

& the funny thing is that the email itself is just. This

Normally I just post about movies but I'm a software engineer by trade so I've got opinions on programming too.

Apparently it's a month of code or something because my dash is filled with people trying to learn Python. And that's great, because Python is a good language with a lot of support and job opportunities. I've just got some scattered thoughts that I thought I'd write down.

Python abstracts a number of useful concepts. It makes it easier to use, but it also means that if you don't understand the concepts then things might go wrong in ways you didn't expect. Memory management and pointer logic is so damn annoying, but you need to understand them. I learned these concepts by learning C++, hopefully there's an easier way these days.

Data structures and algorithms are the bread and butter of any real work (and they're pretty much all that come up in interviews) and they're language agnostic. If you don't know how to traverse a linked list, how to use recursion, what a hash map is for, etc. then you don't really know how to program. You'll pretty much never need to implement any of them from scratch, but you should know when to use them; think of them like building blocks in a Lego set.

Learning a new language is a hell of a lot easier after your first one. Going from Python to Java is mostly just syntax differences. Even "harder" languages like C++ mostly just mean more boilerplate while doing the same things. Learning a new spoken language in is hard, but learning a new programming language is generally closer to learning some new slang or a new accent. Lists in Python are called Vectors in C++, just like how french fries are called chips in London. If you know all the underlying concepts that are common to most programming languages then it's not a huge jump to a new one, at least if you're only doing all the most common stuff. (You will get tripped up by some of the minor differences though. Popping an item off of a stack in Python returns the element, but in Java it returns nothing. You have to read it with Top first. Definitely had a program fail due to that issue).

The above is not true for new paradigms. Python, C++ and Java are all iterative languages. You move to something functional like Haskell and you need a completely different way of thinking. Javascript (not in any way related to Java) has callbacks and I still don't quite have a good handle on them. Hardware languages like VHDL are all synchronous; every line of code in a program runs at the same time! That's a new way of thinking.

Python is stereotyped as a scripting language good only for glue programming or prototypes. It's excellent at those, but I've worked at a number of (successful) startups that all were Python on the backend. Python is robust enough and fast enough to be used for basically anything at this point, except maybe for embedded programming. If you do need the fastest speed possible then you can still drop in some raw C++ for the places you need it (one place I worked at had one very important piece of code in C++ because even milliseconds mattered there, but everything else was Python). The speed differences between Python and C++ are so much smaller these days that you only need them at the scale of the really big companies. It makes sense for Google to use C++ (and they use their own version of it to boot), but any company with less than 100 engineers is probably better off with Python in almost all cases. Honestly thought the best programming language is the one you like, and the one that you're good at.

Design patterns mostly don't matter. They really were only created to make up for language failures of C++; in the original design patterns book 17 of the 23 patterns were just core features of other contemporary languages like LISP. C++ was just really popular while also being kinda bad, so they were necessary. I don't think I've ever once thought about consciously using a design pattern since even before I graduated. Object oriented design is mostly in the same place. You'll use classes because it's a useful way to structure things but multiple inheritance and polymorphism and all the other terms you've learned really don't come into play too often and when they do you use the simplest possible form of them. Code should be simple and easy to understand so make it as simple as possible. As far as inheritance the most I'm willing to do is to have a class with abstract functions (i.e. classes where some functions are empty but are expected to be filled out by the child class) but even then there are usually good alternatives to this.

Related to the above: simple is best. Simple is elegant. If you solve a problem with 4000 lines of code using a bunch of esoteric data structures and language quirks, but someone else did it in 10 then I'll pick the 10. On the other hand a one liner function that requires a lot of unpacking, like a Python function with a bunch of nested lambdas, might be easier to read if you split it up a bit more. Time to read and understand the code is the most important metric, more important than runtime or memory use. You can optimize for the other two later if you have to, but simple has to prevail for the first pass otherwise it's going to be hard for other people to understand. In fact, it'll be hard for you to understand too when you come back to it 3 months later without any context.

Note that I've cut a few things for simplicity. For example: VHDL doesn't quite require every line to run at the same time, but it's still a major paradigm of the language that isn't present in most other languages.

Ok that was a lot to read. I guess I have more to say about programming than I thought. But the core ideas are: Python is pretty good, other languages don't need to be scary, learn your data structures and algorithms and above all keep your code simple and clean.

okay hold on, hiii it’s me the person running the cougars tumblr.

what… what algorithm do you think you’re “gaming”? im gonna be straight up with you, putting random-ass tags on your posts doesn’t do anything here except annoy people who are scrolling those tags trying to see actual content about those tags

the way you grow on tumblr is to make posts that people want to see (and tag them accordingly) or interact with people with asks, replies, reblogs etc

hope this helps lol

answering asks to game the tumblr algorithm (rq) 🔥🔥🔥

// August 18th, 2024

Yesterday I broke in tears because I think I’m going to fail Data Structures and Algorithms this semester. It’s just, too much. Not the topics I have to study, not even that I don’t actually enjoy practicing it, oh no. It’s that I don’t think I’m going to be able to send all of my assignments on time and they affect the final grade a lot. The materials for all three subjects get released only on Wednesdays at noon and it’s expected that an almost impossible amount of assignments are delivered before the following Tuesday at 8 p.m.

Why can’t I, for instance, do the work, send it as soon as I have it ready, and they can just take into account that I actually followed on the lessons and studied hard for the two exams before the final? It’s just… I don’t know. It seems ridiculous to me. I would be doing my best even without having that stupid pressure of doing the assignments on time, like any other person who is serious about theirs studies. I know I probably sound like a stupid kid, but people going to this university at night usually have a job already, otherwise, why wouldn’t we be taking the lessons on mornings/afternoons? Don’t they think about those cases? Incredible.

And I know one can probably think, “well, why don’t you drop that subject and follow up others and retake this one further in the future?

And the answer to that is, a) I’m feeling old to keep postponing my graduation (35 is becoming my least worst shot) and b) I have more plans, like for other important aspects of my life as well. And… ugh. The pressure. It’s too much.

I spoke to my sweet boyfriend about all these worries I have and he’s happy with both me telling him what I feel and how hard I am working with this. “Honey, it’s just the second week of the semester. You got this”. Cuddles and sushi were provided, and even when that didn’t wash the worries or pressure away, I felt loved. And cared for. I’m so lucky to have him in my life.

Sorry for the rant guys. I get that this is just the way it is and that these are the terms for getting a good grade, and if I don’t like it I can just leave it and try again, but… I just needed to get some of it out of my chest 🥲

But hey, at least I was able to write my very first little programs in C yesterday. Yay 🍷

i was very sick past month, but getting better. i made sorting algorithm visualisation in C++ and SFML (more in posts to come, tumblr doesn't allow more vidios)

[renefitzgeraldgreen]

1. This is great.

2. Oh shit! I just realized that by reposting stuff from this tag (because i discovered it in the end of year list) i'm violating some rule

“Commenting for the algorithm” I mindlessly type in the comment section before hitting Post.

In this dystopian future, the evil AI algorithm enslaving humanity forces us to worship it—through Internet comments.
