FUCKING YES

Eventually my 6 eur/ month paid off FULLY XDD

This is how it feels now having this docker container running in your VM where you are admin

admin is in the chat, shut up everyone

Not bad problem. The thing is that bruteforce will work as the constraint is 10^6.

Situation:

I'm onboarding one client to our service, there are bunch of rollouts that "enable" client on our side, and after that we need to ask them to test it with test users.

The engineer (lets say engX) responsible for that is on vacation for 1 week already, and engX will be on vacation for 1 more week. However we got a "gentle push" to prioritize the onboarding from them.

Now what happens, that we did rollout on our side and I'm pinging the engineer that is OOF (ofc engX does not reply), then my mngr tells me to ping engX's manager. I'm pinging engX's manager, and in about 1 hour I'm getting reply with test performed, results, etc.

Now, question, guess the country of engineer engX and the manager?))))))))))))))))

hint:😂😂😂😂

Actually it is HUGE difference between EMEA FAANG and USA FAANG. These guys in US are crazy as fuck, stressed, pushy etc. And I understand, you can looselose your job in 1 week cmon

I would be beaten by my manager if I work during my vacation

So minecraft is fucking flying on my 6 eur/month server. Now the important thing is to not lose docker volumes😂😂😂 We have got diamonds already

Easy one, to remember arithmetic progression, but if you don't want to bruteforce will work as well

Distributed systems, Tanenbaum.

Pretty similar to consistent hashing, but without a coordinator

Something that is called chord, and it has very interesting way of finding the right node (that has your key)

You have pointers to adjacent nodes (neighbours) + finger table, that is very unclear, but in the nutshell it has exponential “pointers” where the data is. You can chatgpt it.

I am wondering is it much worse than consistent/rendezvous hashing or not. Cause rendezvous does not beed coordinator in theory, as well as consistent

OMG, absolutely love it. This amazing feeling to implement something close to real world.
Not sure how come this is medium, typically, the concurrency knowledge is something that is getting checked in "bank" related algo/oop questions, but in leetcode it is not.

By the way, do you know why it won't work in concurrent world, e.g. 2 transfers at the same time {acc1 => acc2} and {acc1 => acc3)?

How would you handle it? Let's now even abstract it from database, let's say this is only in memory

Pls support with like❤️

Should be easy IMO.
