We have got first Technical Reviewer for the article🥳. Kudos to Bohdan, he found nice gaps and misleading parts, thanks!

The more I work in tech the more I understand review - is always a must

I'm very happy and proud that here we have high level people who can do nice technical reviews and know a lot of internal/underhood stuff.

Easy again, but be careful, this easy WILL NOT accept bruteforce (as typically easy problems do).

No pattern here.

mailchimp - suck my balls. Switched to kit.com -> incredible experience, easy to set up, clear instructions, didn't have to buy email in my DNS provider.

kit -> I recommend
mailchimp -> I don't recommend.

BTW kit didn't pay for that, unfortunately, I wish they did.

Good thing about mailchimp - it allowed me to export all 90+ emails that subscribed to news letter. So now I will be able to run a "hey there is new article - go and check it". Now I'm as annoying as all these blogging platforms.

I just don't know how else to retain folks that got interested in article, but didn't follow telegram or something, because they don't have it.

I'm wondering, how is it useful overall these "email news letters". I have zero subscriptions like that, not sure about that. But better to have than not to have

Hopefully I won't get banned

I'm very scared about tomorrow, as today we've got third day in a row with easy Daily question. Pretty trivial one, and again no pattern

Recently I saw one reel about discipline, and it had quite good insight.

To maintain your discipline and consistency - don’t expect yourself to do daily tasks (reading, leetcode, exercises, whatever) with high energy, performance and quality.

Sometime you do 60-70% of your performance, e.g read 10 pages instead of 30, solve easier problem, but still you did it. This is the way to go. This is what I do as well.

Pretty easy problem I would say, just don't miss one edge case: "inini" -> "inini", not 'niiin'.

No pattern, so skippable.

Are there rust folks? I mean I am working on rust project but I dont understand rust much.

The question: piece of code that I have seen in threads, in any other languages, will lead to lost updates in concurrent environment.

BUT rust has this “mutating borrowing”, and I don’t know the internals and specifics. In theory, if only single thread can mutate state - it should be thread safe by definition. But maybe some experts can correct this statement.

I mean, the trick and magic should be happening on calling side, where we have balance variable, and how we leverage result of this function to update it. Function itself is just pure func, nothing special

Actually no. I hated it xD. When I was starting especially, because I didn't see real application for my work back then (honestly it is not much application even today). But I have very weird psychological peculiarity. I might hate some activity, but if my consciousness is convinced some "activity" is feeding us -> I can get tons of motivation and even enjoying becoming better in that activity

So my states were: "wtf is that why I need it" ->
"let's try, others for some reason are doing that" ->
"okay, this is the only way for big tech" ->
"oh, it can make your salary twice or tripple larger, we are going to become good here"

Another piece of motivation, that always worked for me: “this is exclusive thing not that many people can do”.

Selfish? Yes. Works? Yes. That was part of my motivation to start enjoying math, as I hated it most of my childhood. Part of this type of motivation applies to Leetcode ad well

And third one: grinding, lineage2 way. I wanted these 750 solved, I wanted cap, I wanted this ✅ “I did it”.

Tell me the most embarrassing mistaken English use?

I am personally B1-B2, and today probably was the worst case.

So three my friends and I were sitting in the kitchen. One guy was showing me the car he wants to buy, and I said:
“Will you ride me when you buy it?”

😁🏳️‍🌈👨‍❤️‍👨

I mean, only after 3-5 seconds I realized how it sounded😁. In Ukrainian it sounded okay in my head

For the future, you should say: “will you take me for a drive”

Like really. Wtf?

Worth mentioning, they fucking did it right! If the window is not “fullscreen” it works. It just does not work, if the window is fullscreen, and then moving it to another display.
