My prof sent us link to Tim's channel to learn python. Little did she know, i had been doing that for a year now

Knowing Linux is a key component in fitting into the IT world.

Good video. One thing tho... A more elegant way of setting the user variables, is to edit and add variables to the .bash_aliases file instead of adding them directly in the bashrc

What is the difference between .bashrc vs environment file?

I'm thinking about switching to Linus from MacOS for my next setup, but I'm so comfortable in the Apple ecosystem as a programmer that it's a hard choice. With the new M1, things are broken and it seems like a good opportunity to switch, but decisions decisions.

Hi Tim, awesome vídeos, i would like to suggest a full series about software design. It would be awesome.

Been watching some of your Python and Linux videos. I know this is a bit off-track, but what is the name of the tune you use at the very end of your videos, like from 13:23 - 13:30? :)

Hey Tim, Please make videos on Ursina Engine in python

I am the first one to comment
This is a very good video

[bojanjeremic]

I think you should do video on godot, since gdscript is very similiar to python

Is VScode better than PyCharm for Python ?

[pravinthakur]

Needed a competitive coding partner with whom I can start my competitive coding journey .Anyone interested please reply?

I set the speed video to 2. And I think that the speed of your voice overpass the speed of light

UNIX like FreeBSD and Solaris is also a must have skill for any programmer as is Assembly and debugging with Assembly! Surprised not many mention this. SQL on the other hand is barely relevant in 2021 and not really a must have skill anymore.
SQL is on its way out like Java and Cobol so it's a waste of time to invest in learning any of these 3. C++, Assembly, C#, Python, Solidity, Linux, and UNIX (FreeBSD/Solaris) are must have skills for any programmer for 2021 and beyond! Also being able to write a simple compiler in Assembly is a great project to add to your portfolio!
