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…
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😁

btw we are 2.5k on YouTube!!

LeetCode cap did its work xDDD skyrocketing

Thank you for being with me. Hope it is fun/interesting/useful for you at least sometimes

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

Perfect time to talk about schedule. Please share your one!

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#)

Really like go check almost any open source thing: nginx, envoy, postgres, redis, sqllite. And tell me fucking code is easy part🤡🤡🤡 and it is only networks/storage. Lets see game engines, lets see microcontrollers and embedded systems. Lets see LLMs inference code, any machine learning engine essentially. Lets see any compiler or interpreter

You know I'm a bit addicted to sharing knowledge with people, and it is unbelievable feeling, when you can share something you have been working and studying for long time and see it helps people.

BUT

Seeing people contributing and using your software - IS DIFFERENT LEVEL of dopamines/endorphins🥰

Daily 366th day streak

Don't be scared. The problem is essentially easy-mid (if you have solved 3-4 game theory daily before).

Good problem, has pattern, I recommend.

Hahaha, I want to be more toxic, but it will be inappropriate.

Yes,
Writing a poem or book - is easy, it is just words.
Writing a song or music is easy - it is just notes
Writing new formula in math is easy - it is just numbers and letters
Writing a newly found dna, or element - is easy - again, just letters

“Yes communicating with people and agree on design and architecture is the hardest”

Dude, from the same argument it is easy - it is just saying words, and drawing rectangles.

Fuck my life. I dont know, but I legit have feeling these folks never wrote anything than 2 get endpoints.

===

Ofc the problem lies in definition, I literally cannot decouple writing code from what it means. Because writing is the operating over ideas and underlying hardware which is implied you should know. And the lower you go - the more you know , and the more it becomes fucking “coding is NOT easy”

I wish to see them doing “coding is easy” on random opensource issue in 1 hour. It is just code, cmmon

Maybe I clown, but to me all such people seemed like:

“I want to be IT guy” , I am doing this for half a year and so I will reassure myself “oh it is easy I can do it” to feel better and relieve anxiety about layoffs or something.

I have been this guy, 4-5 years ago. When I was doing backend on my .net, and literally putting jsons into postgres. Thought, that by reading uncle bob and DDD I know everything.

And now I am dealing with kernel low level network stuff in c, c++ and rust… no, coding is not easy.
