I mean, yeah, sometimes recursion -> iteration transition is SO hard

Solution itself is not that hard. But I have no idea how to come up with it, it does not recall me anything.

Top down -> bottom up conversion is 100050000% easier than this shit.

Today’s stream was pure embarrassment. So I shut it down. Maybe it was due to overworking, as Im doing leetcode for 6-7 hours these days, maybe just in general too dumb for it, idk.

I will restream the same shit on Tuesday. Sorry

Just always remember:

If (0) {//no execution}
If(1) {//will be executed}

and yeah, strongly typed languages save u more time for shit like that than take due to being cumbersome.

Monday, my birthday, and start of Primary oncall. And my present is incident 10 minutes after shift started😁😁

Eh, sorry, stream is not happening today, still busy with oncall

I didn't disappear, nowadays I'm trying to sit on 4 chairs:
- oncall
- feature work (repair on read replication impl)
- leetcode
- linux
- sleep (optional)


On the weekend we are streaming.

Tomorrow the last day before xD.

I have binary search (hate it the most), heap, DP and random stuff like bit manipulation and math (somehow I think I will not be given the task from it)

So around 15-20 problems for 1 day. Let's see xDD

does anybody know why this shit happened?
Yesterday streamed from mac, all seems to work okay, stream was going well on Youtube, but on twitch it showed like stream is going, but there was no visual track at all.
Now I see that recording is actually saved in twitch, and it looks okay.
WTF, is it my obs configuration on mac, is it something with Restream or is it twitch shit?

okay, I have just finished this book. What can I say I wouldn't recommend tbh.

I don't really like the books that are presented as reference, most of the books about the Language, C#, JAva, SQL, etc.

However there were some parts that were quite interesting about the linux internals:
kernel/user modes, processes, threads, virtualization, TCP/IP stack, filesystem, etc, but this is only 10% of the book, therefore no recommendation from my side. Other 90% of the book is just bunch of commands and tutorial about how to run them.

And any commands nowadays is just 1 q to gpt.

in case somebody is interested
