Just skip it, 20% acceptance rate. I had enough at Snowflake today xD. Just don't do this bullshit problem.

Complaining time.

For those who didn't know I switched to Traffic team in Snowflake, which is very infra centric, so typically you don't write code at all, cause everything traffic related is already written, you just need to properly deploy and maintain this.

The typical approach for onboarding in big companies is to give you accesses, wait until you pass trainings and start slowly giving you small tasks so you get used to stack, projects, tools etc. For sure initial tasks would feel like you are put in dark room without lights and you need blindly to find exit from it.

I'm SO FUCKING TIRED, because it is already 2 months that I'm getting every single fucking new task (now 6th or 7th) that is COMPLETELY in different area, completely different repos, completely different shit with framework you haven't used before, language you haven't used before, 100501st internal tool you haven't used before.

In this endless DFS of exploring I want to fucking hit my visited set and encounter something that I saw before. I don't know maybe it is age, I"m almost 26, or what the hell happened, but it is very tiring for me somehow.

BESIDES that, I discovered that I don't know networks, not even close to the level our staff/principal engs know. Learning a lot of new stuff, and learning via LLM is also so fucking tiring. But there is no other way, all other ways are 3-4 times slower to get medium level of understanding and cover YOUR UNIQUE knowledge gaps that specifically you have.

So right now I'm pretty much studying fucking networks 4-5 hours a day, then studying our tools, stack and flows for 4-5 hours a day, and then that's it.

One thing about Ireland that you must know.
Until you get your PPS number (tax number) you are going to be taxed with 'emergency tax' which is more than 50%.

Enjoy.

Not sure why it is mid, imo should be easy, but I would check answers.

Google docs ????????????? wtf is wrong with 2021 xDD

There is an interesting thing about Prague - you can see rabbits in the city quite frequently. I’ve recorded them a couple of times, and it felt really strange, because back in Ukraine you almost never see any wild animals in cities.

(don't laugh, it was a prime time of famous Polish video BOBR KURWA)

As far as I understand in Dublin it is fox, again, I think this is first time I have seen wild fox in my life

That’s why you should care about high availability, failover procedures, and having enough capacity in paired region/az.

However when I was studying this I never assumed drones being attacking infra 😆 maybe some nature disaster Idk

Did you have any incidents/outages?
Cause I have heard many “fun” nights/mornings from people on call

Complaining time again.
Sometimes I'm getting mad at my body sooo much.

Slept for 6 hours today, during the day got crazy dizzy for no reason (standard random health shit that randomly comes and randomly disappeared on its own)

From 16 till 19 I was sitting on my chair and literally falling asleep, but I didn't, I'm stronger than this shit right. I thought, yeah, today I will need (and want) to go to bed earlier. I would drink coffee, but I cannot, because of stomach problems.

22-23+ - somewhat sleepy but not much, still finishing my stuff to make me want to sleep even more.

01:00 - SECOND ANDRII WAKES UP, crazy hungry, does not want to sleep at all. This second Andrii knows he cannot fucking sleep if he does not eat. But if he eats - and sleeps straight away he will have heartburn/stomach problems, which will push him even further from the moment he can afford coffee.

Cycle is closed. Now I need to chose between being late or damaging my immune system with under sleeping. The choice that is hard to make being on probation and not being sure about local healthcare yet.
I think I need to bring my boxing stuff and start doing sports, maybe this will fix

I realised I am missing quite some details about TCP/IP stack under-hoods.
One amazing thing about my team, as I mentioned once, a lot of ex-Google Staff Engineers.

So my manager, who is exactly ex-Google staff guy BROUGHT me this book about it that he was reading a decade ago. Now there is no way I am not finishing it. Be ready to screens from it and interesting highlights
