Omg, 35 likes, will do within the next 1-2 weeks, and with simple POC. I think this is good traction.

First finish interviews article that I promise for a long time, and then switching to Messenger.

This is sooo zoomer zoomer thing😁 I caught myself going to threads while waiting for cursor, but I forcefully make myself to not do that.

Lets bet: I truly believe if humanity overcomes ethics - this is AGI potential in the next 10 years. I knew about it earlier, but now even Prime is talking about it

Not bad problem, but pretty hard (for me), but it is graph related problem therefore - I like it

I'm not sure about this problem. It requires a bit of math, but overall, not bad

This one is not forgotten, today I am coming back to Dublin and will start working on the article. Since it got like record (53!!!) I will also add a bit of visuals for system design (God blesses AI agents).

Your opinion and feedback is really valuable.

Daily (218/373 streak until LC cap)

Bullshit a bit in a sense that 99.999% this will never be needed in real interview, as it is math and specific theorem needed.

Sorry, I'm after Kinedryl, so I'm still flying high after the flight to Dublin, I can't really grasp the math. My advice - skip this nonsense for now.

People generally don't like this q, but keep in mind it can be solved as bruteforce

Basically no pattern here, just some unique trick (some people suggest you need to do 2 hards to understand the intuition, but I wouldn't agree with that fully). Added simple visual for building the intuition and solution explanation

Trully believe this is the trend, and hope it will stay the same so they don't fucking fire everybody

Good, pretty easy problem. Actually uses leetcode pattern, so highly recommended

Posting random quotes from the book to recall the fundamentals.

Some years ago as I was exploring tcp/ip stack practically, I created HTTP server using tcp layer, but I was wondering HOW CAN I write my tcp implementation. The answer is here: everything below tcp(inclusive) is kernel mode. So it is not that easy/impossible to replace it with your impl - so you got to work with socket() os api, and choose between udp/tcp.

Pretty same problem as yesterday with small modification.

ahahhaha. The guy contacted my colleague in Linkedin with: "can you share the questions you have been asked during the interview".

He shared general recommendations and sent my article. Literally the same guy after 5 mins:

Bruteforce works here, just emulate what is said. I'm looking forward to end these matrix problems, don't like that, they all are somehow cumbersome or something.
