And investigating with AI is crazy exhausting if it is unknown thing.

I self reflected why. With ai, anything it told me can be hallucinations and false. So after asking 5-6 questions about how it works and what can be the root cause - you have tons of combinations of which of these might be false.

And therefore it is painful to even try to ground up your conclusions on these AI answers. Or if you do it, you wasted 1 hour to build it up, and then you realize, well, motherfucker hallucinated, now I need to unlearn, and build the opposite mental model and ground up different conclusions on top.

Literally the same conversation (the fucker has access to all the skills, logs, mcps)

“Are these the connection of type A”?

- yes

(Opening different chat and somehow realize they are type B)
(Going back to original chat)

“OR MAYBE THEY ARE FUCKING CONNECTION OF TYPE B??????”

- yes they are connection type B


????????
????????????????????????

Sorry, I gonna check all the comments by the end of the day.

Guess who is working all weekends for this AI shit? Yes, Andrii is working…


For daily leetcode - yesterday was skippable stuff. Pretty complicated thing without much patterns. For today I will post

I am sometimes rethinking life choices, as for now I could have recorded videos from inside of that office😁

Not now, but someday folks, I WILL record from that office. Take a screenshot.

Daily 363d day streak (yesterday)

Extremely complicated codeforces shit + didn't have time yesterday. No patterns pretty much. I would recommend to skip.

Daily 364th day streak

Not bad problem, pretty unique in a sense, never seen such intuition behind it.

This is brilliant.
Yes, it is a tradeoff as in basic computer science:
- you have quick writes but long reads
- you have slow writes but long reads

That's it. And I was always respecting people and projects that respect other's time and make bigger effort on write (the code) so that it is much quicker to get the mental model when other 15+ colleagues are reading the code

this is exactly what happened with our AI proj at Snowflake.
The code was pushed quicker than people can track it and save it to brain.

Now the complexity is too high to comprehend. And now human either asks LLM to fix the error and prays, or needs 2 weeks to understand how shit works (still with ai, cause you fucking cannot read 2-3k lines of rust function)

I'm not joking about 2 weeks.
I had to do knowledge share about our CRAZY COMPLICATED THE HARDEST TO COMPREHEND IN MY LIFE custom PKI/Certificates.

took me 2 weeks to draw down the excalidraw diagrams. It was seen during the meeting people didn't understand shit out of my talk about certs (however it was crazy distilled, easy-to-read-hard-to-write snapshot of things).

I already see how beautiful the oncall will be for that thing😁

Daily 365th day streak

Good problem for Game theory, we had bunch of them few days ago. Definitely recommended, it is "subbranch" of DP problems. And it is not that hard, harder than prev ones, but doable

I FUCKING SOLVED AI PUZZLE, just sat calmly and microstep by microstep investigated.

Now waiting for tests to confirm, and solve daily for tomorrow. Amazing feeling, amazing vibe 3am.

Not all would understand, but this is fun for me😁

I will never stay if I dont want to. I cannot make myself usually😁😁

I got a right vibe, I got involved and felt challenge I wanted to solve for myself. Tbh I didnt really care about Snowflake yesterday, it was personal😁

Side thing, manager understands and I will get 1 vacation day for that.

In general people very strict about employees to BE on vacation and TAKE vacation, it is EU. But, I am the guy who goes office every day, cause I like it. Aaand, I am usually starting late, during working days (you cannot find me in the office before 11:30). And they are somehow okay with that, therefore I am staying late. If anyone would tell me “you must come before 10”. I would stop doing that for sure

Btw, is it a YEAR OF SOLVING DAILY NOW???😎

He had something to say.

They are so cute here, and at the same time mafia style birds. They can steal your burger from hand (I have heard stories)

Ooooh my god. Sorry, but I agree with that guy. Moreover I believe that people that say “code is never a hard thing” never actually did anything except printing html button or putting json from one storage to another storage.

Go and try write low level kernel networks thingy with rust or c. Let’s see how “coding is not hard part” 🤡.

Maybe they think code is just syntax, which confirms my above’s point, cause if you try multiple langs, you will see how at least thread model and async/await model is different. How memory management is different (AND IT IS NOT EVEN INCLUDING NON-IMPERATIVE LANGS LIKE SCALA, F#)
