thank you so much guys for doing this. very instructive and entretaining at the same time

12:40 Conditional check version - it's irrelevant that the first check is for 1% of cases, because a second check needs to be performed either way. The real reason this is typically a wasteful complication is that it branches; if you're lucky, it compiles down to a conditional move with speculative execution, if you're not it uses the branch predictor, slowing other conditions but not fully compensating here. The conditional move is no faster than the logic operator it replaces. The branching does make sense on computers where the pipeline is shorter than the latency of the division operation if it is not capable of pipelining 3 divisions - e.g. the RP2040 has a divider but it takes 9 cycles to operate and does not pipeline. The modulo 4 operation can be done by a bit mask, so the divider might not be as busy as the code suggests.

this video is so good this is perfect level of detail and info for someone ready to learn rust!

I feel so dumb after reading some of the solutions to this. I guess I'm a long way from advanced programming.

Is there more low level type of code than Assembly?

35:35 Why can not be consedered the code as a function or method? At the very end it is executing some set of instructions that resolves a problem!

34:21 Hi! Great video!!! Am I right wondering that the last dot on the third line is the end of that function/method? Greetings from Argentina!<3

AMAZING walkthrough! For those solutions that map to hexadecimal three character value, it would be nice if they instead mapped to six bit, since there are only four valid acids, two bit each. The very big numbers are not meaningful, to my shallow brains, but numbers 0-63 are easy enough, especially as binary.

Well, I have 0 idea of Scala, but if you have to synchronize the write access to balance and also the returning in your increment method, it does not seem logical to me that getBalance() can just return the value without any synchronize() around it. That might work well for an atomic operation as the changing of a single Int will be, but will fail catastrophically if it is a multi-step update and the getBalance() would just return the partially-updated object.

Hi there, what happened to Erik?

Want to take part in the Bootcamp? There's still time to join! Enroll at exercism.org/bootcamp

Video start at 22:30

from where Bjarne Stroustrup get idea to add class concept in c++

This was awesome! Thank you very much for sharing how this works behind the scenes.

i just signed up. when will you contact me?

U meant exorcism don't u.

Bad sound quality, echoing off the walls...Maybe hang some curtains around the room to absorb sound...

you look kind

Just came across this. Can I start and just get these done when I can, 2024 or not?

Will there ever be a full stack bootcanp with node?

Isn't 'A' unicode equal to 65? Wikipedia shows 41 as ')' So why in 22:50 Actual result shows first char as 'A' not ')' despite code showing \u{41 300} ?

The didactic here is amazing. Thank you for this!

If Gleam could be written in Livebook I’d go all in, unfortunately Livebook is such a crucial and useful tool i must admire from afar.

Very nice! It's like Matlab but actually good and performant :D I looked into this years ago when I was doing my PhD, but it was quite immature at the time.

Sincerely looking forward to this!

I love the ideas for projects, I would gladly steal them for my own hobby ones! Also loved Breakout on my computer called Arkanoid :)

I'm almost sad, that I already know coding (and had to do it the hard way). I hope many people can have an easier start with a good BootCamp that will actually help them to start coding with your method!

I think the main reason why people give up has nothing to do with coding but with learning. Learning is practically always uncomfortable. Your brains love to do stuff they already know and the brain hates new stuff because it requires effort. So to learn (no matter if code or anything else) you have to understand that learning is always uncomfortable. Once you understand that you can try to manage it by limiting the learning time (split time between stuff that's new - and stuff you already know/repetition). Also prepare mentally that learning is an unpleasant experience.

Bravo!

This is great stuff indeed @JeremyWalkeriHiD! What's the deadline to enroll?

Can't wait for it to release!

Awesome, good luck and welcome to all new programmers!

Super exciting! 🎉

So excited for this! 🎉

20:15 This was also my first thought for my Rust track. But the first attempt at implementing this, ended up with serious struggle in getting mutables of surrounding cells. We also end up checking all the surrounding rows, if they are not a mine, anyway. So, this solution just multiplies amount of writes we need to do, so I've abandoned it.
