Easy problem without any pattern pretty much. Go and collect the coin it is 2 minutes problem

Let me share the pain, and tell you HOW NOT to do software engineering.

Skill number1 you should have over your service: being able to quickly understand that some specific merge to master/main is in some deployment or no.

Typical application: you merged some fix pr that changes behaviour, you have 20+ deployments that are deployed incrementally, and you want to know whether this specific fix is in the deployment you are interested in (lets say some oncall has paged you and moved to bridge call asking this q).

Usually you have 2 things:
- metric that reports version per deployment
- tag WITH THIS version on the main branch that represents the state of code that got deployed.
These 2 MUST be easily correlated. So version on the dashboard and version on the tag must be either the same or easily derivable.

Now imagine, somebody created a service, that has version coming hell knows from where, git tags that contain completely different numbers and words comparing to version in dashboard, and here you go: some guy is asking you: can we check this thing is deployed to region X?

Guess how much time I spent to confirm it?
Did I confirm 100% in the end?
I as AI successful in helping answer these questions(has access to docs and git)?
🤡🤡🤡🤡🤡

I’ll be honest, sometimes I feel warm nostalgic feeling to Epam and other outsource companies. Maybe I was lucky, but typically I had so small projects that I could have context ABOUT WHOLE project at a time.
You know everything e2e, you have FULL mental model in your mind.

I didnt have this feeling for 5 years now😆

The easiest "hard" problem implementation I have ever seen. Good problem, a bit hard to come up with intuition: check discussion tab.

My advice: try to think greedy: which task to process the first and what you want to have as the first task

Pretty hard problem, should be hard definitely. And solution is pretty unintuitive.

For some reason didn't go from the first try for me today XD, maybe too much work at Snowflake.. But in general it is pretty easy

All this time I was trying to understand how vibe coding feels like to me and in general how my working day looks like.

Pretty accurate

Today solid, good problem in first 200 Leetcode problems. Nice to recall binary search. Not that easy, requires to "go through examples" a bit.

Actually can be solved with bruteforce with one line, but the solution is expected to be better than that.

Yeeeeah instagram realized in 1-2 years I am done, and will need a switch. I clicked, no jokes

Nice problem, it is not that hard, except one peculiarity that you need to do. It is good and has well-known pattern. Definitely recommend.

Yesterday’s dinner. Maybe you have already seen this guy, but I definitely recommend watching.

Atlassian laid off dev is showing system design of their infra. Pretty good system design btw. A lot of similar stuff we are doing at Snow rn.

Folks, do you see the last message with link?
