If you want/need for tech review I can mention you as technical reviewers so that your contribution is visible for everybody else

Officially stating, fuck windows - the worst shit humanity ever created. I gonna switch to linux, I WAS FUCKING WAITING 2 WINDOWs, LAPTOP TO FUCKING LOAD ME YOUTUBE TO WATCH MORNING STARCRAFT FOR 15 MINUTES!!!!!

in general, WHAT THE FUCK is with software, why ALLL is SOOOOOOO SLOOW. Maybe this is my childhood memories but I do remember how windows XP was fucking fast, everything was loading instantly.
Now (talking only about windows) and specifically windows products. Want to open browser - take you 10 secs, want to open teams - good luck, 1-2 mins on cold start + 1 more minute to load fucking 1 week of calendar (that's why I always late 3-4 minutes on the morning stand ups).

Fucking azure dev ops ui, you want to return from the specific build page to ALL builds page - wait youir 5-10 seconds, WHAT THE FUCK HAPPENED TO SOFTWARE.

I don't know I'm thinking too fast for this load time, it is painful all the time to wait until some page loads, when in my mind I'm already 3-4 steps ahead

Daily is not the easiest one, a lot of edge cases, and requires pretty deep analysis of the problem.

wow, eventually I got contest rating

the chart recalled me a bit

I guess I'm something like this on leetcode rn

today is very bad day, extremely fucking bad day. You know when nothing fucking works for you.
Now I try to pull the git repo for some course that I'm studying, and people are uploading there their changes.

AND THE FUCKING FILE NAMES ARE NOT COMPATIBLE, because they contain spaces or something like that I believe

why git does not prevent merging such shit by default, fucking macos/windows compatibility

Today's daily is not that hard, but for me it was hard to come up with optimized solution, so I had to look it up
