It was that meme: “guys’ faces who only join sparring and never show up on regular training”, and they proved the point to me ahhahah

Daily 412th day streak

I was not able to solve in reasonable time. The problem is amazing otherwise (except very poor explanation/definition). Definitely recommend. I will work later today on more solutions and understanding of them.

Daily 413th day streak

Pretty easy problem tbh. No specific pattern though, and sort of does not feel like bullshit, more or less applicable.

So I got interesting thing about my body.

Probably all of you are getting 1-2 times sick (cold) per year (at least this is how it was for me).

I noticed few years, that if I have some important events in life (like meeting somebody, interview, oncall, etc) - I subconsciously tell my body: "we cannot get sick now, later". AND IT WORKS!!! (most of the time).

Then once important event is done, and I'm relaxed, same command: "now we can have sickness for a bit" and then it gets worse as usually sickness should go.

Do you have the same?

Well well well

Who you wanted to be in childhood?

Software engineering - was definitely not even top5 in my list 😆
