Learn how to code the object pool pattern by pre-allocating memory and reusing objects. Which can greatly improve performance when reusing short lived objects like bullets and particles.

This tutorial will show you how to create and manage a pool of bullet objects. For example, this is useful in shooter and bullet hell games which have thousands of bullets on the screen.

The tutorial is written in the Java programming language, and uses the free Processing graphics library and integrated development environment.

The object pool pattern can be especially useful with programming languages which use automatic garbage collection like Java, C#, JavaScript, Python, etc.

Since automatic garbage collection can stall your program and reduce your frame rates. The object pool pattern gives you more control over when the garbage collector comes to reclaim the memory.

The downside of the object pool pattern is that it complicates the life cycle of the object. Meaning you need to reset the variables of the object before you can reuse it. Since its variables are unlikely to match the defaults after repeated use.

There are a few ways to implement the object pool pattern, this tutorial will show you one method.

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.

Records and data transfer in Java

So a colleague of mine was curious about the Data Transfer Object pattern, DTOs and specifically Records in Java, so I decided to write smth about that. You can find it here:

Pattern programs in Java are exercises that involve printing various shapes and designs using loops and conditional statements. These programs help developers enhance their logical thinking and problem-solving skills. Common patterns include triangles, squares, and diamond shapes, often created through nested loops, showcasing the versatility of Java in graphical output. Check here to learn more.

Flux Design Pattern using TypeScript in React

Flux is an interesting unidirectional architectural design pattern introduced by Facebook for React. React has unidirectional binding, unlike Angular which has bidirectional binding. It is the same pattern used by in Redux, which is very popular JavaScript library for statement management. It is important to know that Redux is not the only state management library, other possible choices are…

i 100% absolutely cannot i repeat CANNOT allow myself 2 fail this course bc this is my last chance at taking it otherwise im removed from the program but i

cannot make myself do the work. i can't start. we're halfway thru the term ive lost a HUGE percentage of the grade already and i sit down 2 start googling how tf to do what i need 2 do and i fucking c a n t and now the whole course has become this hot-stove-item in my brain and im lying in bed practically vibrating with anxiety abt to let another (re-negotiated!!!!!!!) deadline pass and like!!! why am ilike this!!!!!!

ANYWAYS if any of yall know literally fuckall abt python...... pls........ 🙏 help........ 🙏
