When I was 13, I used to wonder how the refrigerator's lights went off automatically.

i like how youtube keeps reminding me of my lack of talents.



Edit: to everyone in the comment sections. Don't compare yourself to anyone. You can't really compare yourself to Terence Tao who learnt math at age 2.

At his age I was trying to balance the switch between on and off.

I'm 11 and I am the lead software engineer at Apple, Google and Microsoft. I am also at the forefront of sub 1nm semiconductor research with Galium Nitride/Carbon based transistors.

This kid has better naming convention as my "senior" devs with 12 years of experience.

Plot twist - the developer is a grown ass man but pretending to be 13 so that he can be judged less.

[Bankeys]

I am 3 just wrote my first operating system kernal

Welcome back to the first episode? Sounds like an infinite loop bug to me.

13years old ? Well I was building some "Hello World" batch programs and trying to delete system32 folder and calling it virus back then😂

This is a great example of "there's always someone better than you" - in a nutshell, it's pointless to think you're the best at something, always strive to learn.

13 year old - Try to copy string
Cherno - bruh.

13:57 Not a big deal, but since you were commenting on it any way: Since char is in the 0-255 range it would be more lookup-performant to just have an array Character Characters[256]. Or better, since printable characters are in the 32-126 range, you could have an array of size 94, and offset by 32 when indexing into it. This is of course assuming you don't start doing unicode stuff, where you may want to either have multiple ranges, or some hash map (that ideally is optimized for this purpose, not just a general std::map). In general, if something is indexed by an integer and the used keys are tightly packed, just use an array instead of a map (wrap it in a user class with error-checking methods if you are uncomfortable with a plain array).

When i was 13 i was naming vars butt. 13 years later im still naming vars butt.

If you are interested in doing Vulkan and need a library, I would be happy to hear your feedback about liblava.

It is still in the preview and there is a lack of documentation, but with the tutorial and demos you can get along, I think.

Stay healthy!

18:06 std::vector::at is not returning a const ref because the member function itself is not const. The difference between operator[] and 'at' is just that 'at' does bounds checking and throws an exception. Also noticed this is plain old C++98, no -std=c++<x> flag.

“Welcome back to the first episode” Think about that for a minute.

I just wanted to mention that I remember following your Java game programming tutorials as a kid. You 100% changed my life by giving me such a great introduction to programming. I'm now pursuing an undergraduate computer science degree and will be interning at Google for the second time next summer! Seriously thank you for all of the quality videos you've produced over the years. I'm so glad that you're still making content too.

[Avean]

I am blown away if this guy is truly 13. Even his e-mail in the beginning is perfect without any typos. I was expecting "here is my codez lulz!"

[farbodshahinfar]

Awesome code review video. I did enjoy getting through the code. I came here to have a break and found the background music really interesting.

[pokimane]

Thank you for reviewing my code i really appreciate it
