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.

What Transport Protocol DNS uses
Answer: UDP, from performance consideration. DNS itself is Application layer protocol (same as HTTP, FTP, etc)

My friend, lately had interesting experience of taking Production Engineer at Meta interview.

The interview type is Linux Troubleshooting. First time he had such interview, and it was quite interesting.

In short:
There is deployed web app (frontend, backend and database) on the single machine, single datacenter. There is alert that checks http status code by curl the host.
At 2:06 AM you are getting called by alert that server is down. You have root access to the machine.

Your task: trouble shoot the issue, find root cause, mitigate and suggest preventative actions.

The interview process is: you are telling what you gonna do, then you tell the exact command to interviewer and interviewer is telling you what this command shows you.

Friend passed the interview with slight help of interviewer

Next stream - we can go through the question, and try to solve it together. Might be interesting experience
