I am stuck step programmer 😂😂

[@daedalus5070]

I could feel my brain trying to stop me writing what I knew was an infinite loop but I did it anyway. I trusted you Jeff!

Fun nerd trivia:

[@RedlinePostal]

Also when we say "one-core," that means "one-core at a *time*" -- computer kernels are concurrent by default, and the program's code will actually be constantly shifting to different CPUs, as the kernel manages a queue of things for the processor to do. Not too unlike the asynchronous system that javascript has, kernel will break each program you're running into executable chunks, and has a way to manage which programs and code get more priority.

That chef analogy about concurrency and parallelism was genius. Makes it SO much easier to understand the differences.

Love to see jeff going in depth on this channel, would love more videos like this one.

[@JThompson_VI]

Moments like

[@ra2enjoyer708]

It's a pretty good overview on how much more of a clusterfuck the code becomes once you add workers to it. And it didn't even get to the juice of doing fs/database/stream calls within workers and error handling for all of that.

[@yss64]

Thanks for shouting out code with ryan! That channel is criminally underrated

I'd like to see a video on JavaScript generators and maybe even coroutines.

[@nomadshiba]

talking about multi-threading

[@dzhaniivanov5837]

i watched a similar video early this year, but your way to deliver content is amazing, keep going

[@user-fed-yum]

That ending was possibly one of your best pranks ever, a new high watermark. Congratulations 😂

[@deneguil-1618]

just a heads up for your CPU; the 12900K doesn't have 8 physical cores, it indeed has 16, 8 performance and 8 efficiency cores, the performance cores have hyperthreading enabled but not the efficiency cores so you have 24 threads in total

[@7heMech]

Really cool, I actually saw the other video about nodejs taking it up a notch when it came out.

[@kiprasmel]

the `threads` package makes working with threads much more convenient. it also works well w/ typescript.

[@EdgeGaming]

Lots of comments about memorable descriptions, shoutout to the thread summary at

[@Ihavetoreturnsomevideotapes]

ayo , was learning event loop and had a bit of confusion about performance b/w single and multithreading and jeff just posted the video at the right time.

although it's called concurrent, schedulers still can only work on one task at a time. It will delegate a certain amount of time to each task and switch between them (context switching). The switch Is just fast enough to make it seem truly "concurrent". If a task takes longer than the delegated time, the scheduler will still switch and come back to it to finish.
