Today is pretty nice and interesting problem, that involves a bit of Cortasian plane knowledge and a bit of geometry knowledge, but very basic one.

Where the fuck easy problems???
Today is not that hard problem to be honest, basic prefix sum will work to pass. To make it more optimal - you would need to optimize further. Pretty good medium, I just want one easy problem for break.

A bit of bitwise bullshit, needs quite a lot to build an intuition. Not worth it.

People, are there mobile devs?

I have bunch of questions about how this shit works. Preferably react native / expo guys. Interested in big abstract picture.

I want to ask how hard it will be to port some web thingy to ios/android, and what is even more critical - to make appstore accept it.

Today is pretty hard problem, that involves few concepts that I never heard of. I guess this is the first problem that chat gpt cannot handle as easy as it handles other problems. It is yesterday's problem, but we need to have O(n * log n)

In apartment that I rent in Dublin, I have shared washing machines and dryer. I'm sharing with one more tenant.

There is meter that needs 1 euro for 30 minutes of washing machine / dryer work.

I run out of 1 eur coins, cause I thought 1 eur is per washing, not per 30 mins.

It turned out that 5 CZK and 1 EUR coins are EXACTLY THE SAME SIZE

Save this lifehack :)

some motherfucker, broke it😢

There is time during the year, when I'm getting Vlad Ten's vibe, where I need to do something, produce content, work etc, BUT, I have really huge urge to understand how something works.

I always was a guy who cares only about practical stuff. Then usually I'm starting go deeper with theoretical part and cover all the gaps. This is just how I work.

Last 3 days it was electricity. Cause I have no idea why, I didn't understand how it works, and with that I cannot go deep to learn CPUs.

I will be posting some extremely magical stuff for me, cause yeah, in terms of physics knowledge I'm dumb as stump xD

SO. I was wandering, how our cities are getting the electricity, literally what should happen for me to have lights in my office, under the hood.

Did you fucking know that all electric stations do is just spinning magnets around wires (or vice versa)? That's it.

Turned out that magnet just disturb electrons in wire which is enough to do current. By the way, magnet stays magnet forever, so it is some sort of "inifinite" thing, except you need some work to spin them around.

Ofc in reality it is a bit more complicated, but the general principle is just wiggle magnet, near the wires.
