Linux setup for Competitive Programming (with Geany)

And I would assume the satisfaction of getting getting better will push you even more. Bro not gonna lie I was in a similar scenario 🤣🤣 I just picked the hardest questions I could find and would spend 3-4 days on a single problem, eventually I did succeed in doing a div1 problem without any help but I felt so frustrated calculating how much time doing 600 div1 problems would take me. Then I took a break from cp and learned full stack and built some projects. I now returned to cp doing div2 problems, and doing them successfully has given me a lot more confidence. So I guess the idea is to gradually move up. Hope to move to div 1 in 3 months. May God bless you with success

[@Moonify]

Nice to see you fixed the glitches, I was to tell you that one possible solution to that is going to Nvidia X server settings > OpenGL > Disable Allow Flipping.

I have a new PC and I thought that there are no glitches with new GPU and drivers, but there are some (just very rare). I will apply the fix before the next video.

Gratitude for the awesome content!

[@damcism]

Question not related to the topic of the video: @errichto, how did your process of learning look like when you were becoming good at competetive programming? For example, were you just taking tasks one by one and solving them? Were you reading analysis/solutions of the tasks by someone else? Were you learning that from other people? I know that you have also read Cormen's book about algorithms. Basically, what is the most effective way to become good at competetive programming? I'd be happy if you answered that in one of your vidoes or here - in the comment section. Currently my way of learning is simply: 1. Take a task, 2, think about how to solve it, 3. read analysis of the task (regardless of if you have come up with the solution or not). And obviously sometimes I also implement the solutions. I have also read two books about data structures and algorithms (not Cormen, but similar), so I know the most important algorithms and data structures. I'm wondering if the way I'm learning competetive programming (simply solving tasks and reading analysis) is the optimal way or is there any better?

Hello Errichto, some questions: Have you ever used vscode? What do you think about it? Is there a reason you aren't using it? Also what do you think about different keybindings like vim or emacs style keybindings?

[@SuperArjun11]

Not errichto but plenty of people who are pretty high rated use VScode, most are just used to something else/vscode can feel very bloated on certain setups. Interested what he's gotta say though

[@Errichto]

I'm very happy with Geany so I'm not going to switch. As explained in other comments, it has a built-in terminal and two integrated compilation buttons.

[@w47-p1e]

Can you go over some shortcuts you use when programming? I know a couple basic ones like CTRL + C and CTRL + V but that’s about it.

You can google common keyboard shortcuts that people use. And go to preferences (or help) to see shortcuts of your editor.

I don't uses CPP but I have used Geany for python before as my ancient PC could not handle vscode, sublime text and obviously pycharm. Geany is like more updated version of notepad ++. I would switch between Geany and Vim. But I wouldn’t say it is great. I thought competitive programmer would use something like a heavily moded Vim distribution or emacs.

[@subarnalamsal2303]

Thanks a lot Errichto.

[@mortkebab2849]

Does it really make a difference to the end result whether one uses, say, Geany on Linux or VS Code on Windows? Seems to me that almost all the time is going to be the actions of the human and not the machine so surely what is a familiar environment that is most confortable and efficient, whihch the latter is for me, is the way to go.

[@vijaykryesItsMe]

Most programmers/ cs folk use linux so I think it's more about them getting to competitive code in the environment they're familiar with, not people switching to linux just for faster coding

[@DarshanSenTheComposer]

Great setup! :)

[@thetechegg8859]

Have you used vim? Using it with an autocompletion plugin such as coc.vim and a suitable vimrc works very well!

[@Errichto]

I'm sure that vim is very comfortable but I never forced myself to switch. The beginning is for sure hard. I'm happy with my workflow in Geany though, and it's super comfortable because of built-in terminal.

[@Errichto]

Just remember that it isn't a must! But sure, you can do it.

[@Zandman26]

Suggest you start out that switch by setting up Linux as you want it in a virtual environment like VirtualBox or HyperV. It will be slow in comparison with how it will run on metal directly, but it will give you a backup plan if you do not find all the software you are looking for directly. Also when moving to a new OS you need to really commit to try understanding it, because no OS will work exactly as the previous. So when finally installing it on metal you need to really live in it for a month before you can really access if it's the right OS for you.

[@sreyassuresh1886]

[@marcosteinke]

its the same as the people who keep using VIM for everything. They have their keybinds, plugins, design and have 200% productivity by using their code editor. I am active in the Java / WebApplication branch and everybody keeps telling me to use IntelliJ for everything although I optimized my Workflow in Visual Studio Code during the last 3 years. They do not get why I like working on complex projects with a lot of files without an IDE

[@marcosteinke]

I only use IntelliJ when I get to use Spring Boot, Thymeleaf and Lombok, otherwise it is a overkill imo

[@marcosteinke]

@C S check Wikipedia for VS Code and for example Intellij. It says VS code is a source-code-editor and IntelliJ an IDE

[@marcosteinke]

Difference between IDE and Code Editor: While in a Code Editor you can edit a huge amount of different file types and programming languages, in an IDE you have an environment specialized on one specific programming language such as IntelliJ for Java. It has optimized Debugging Tools, better Project- and Version-Control and tons of other features which are perfectly designed only for Java
