@DaramolaGb Low level open the door that you know every piece how to work behind scenes

Wanted to understand memory management at the lowest level. So I stopped reading about it and built one.

@thepritamlaskar @trying_to_exits What about Facebook?

@AdCodes_ is vscode after sublime after Vim and return to Vs code

be honest, which one was your first code editor?

The only scheduling that has worked for me: Schedule in the long term important stuff and assume urgent matters will fill in the cracks. And 9 times out of 10 urgent (unimportant) matters resolve themselves by ignoring them long enough to accomplish the important ones.

@stijnnoorman Fact also I think to never compare your situation with others like from someone start at 20yo with 20000$ with someone start with 0$ But in the end of adventure the both will succeed

You can: • Start at 20. • Fail at 22. • Start over at 23. • Fail again at 28. • Make a new plan. • Fail again. • Learn. • Start again at 33. And succeed massively at 38. With half your life still in front of you. Life isn’t a race. It’s a journey. Enjoy it.

@stijnnoorman Nice good look mate

I’m 27. If you’re 16–27, listen. Start creating content. Write or record every day. Build a brand people trust. Solve your own problems. Then help others to solve their problems. That’s how you get freedom.

@ennycodes Also don't forget the system design and management skills

Everyone is learning JS/React Everyone is learning AI tools. Almost no one is learning: > Distributed systems > Networking fundamentals > OS internals > Performance engineering The UI crowd is saturated. The systems crowd is rare.
