I think this is the first time I've stopped one of your videos and started actually doing it myself, rather than sitting passively and taking it in. The moment you started doing lists I just felt that this was I problem I needed to try to tackle on my own before seeing someone else do it.

I will gladly spend all my time watching you go through every challenge on that site 😂

[KuldeepYadav-jwjn]

This is the kind of programming content, one craves for on youtube! 👏

I like the way you write a code and tell what the code syntax means, like "rest, until ..len". I learn Rust syntax and libs much faster than reading their docs. Great stuff!

At 2:32:57, you were still passing `t.announce` to `Url::parse` instead of `tracker_url`. That's why it looked like it was stripping off the query params.

Your thought process is highly insightful and engaging to observe. Thanks for great content. And yeah, topic like that are incredibly interesting (live coding of X). I'd be more then happy watching you'r implementing any kind of DB engine, the same stuff as those folks from codecrafters suggest (clone of docker, git etc), browser engine, SQL parser, interpreter or any possible real thing from the fundamental technology we use every day. For example I'm studying Rust, and trying to fill the gaps in my CS knowledge and indeed, building the real things are incredibly powerful approach. And again, watching you doing things, studying your way of thinking and using the language and tools is a real treasure.

I love the idea of teaching you by building something that already exists. I am definetly considering doing this on my own.

Best Rust content on YouTube.

Please do part 2!

I discoverd Codecrafters thanks to your stream. I decided to implement it on my own and only watch your video when I'm absolutely stuck. Funny enough I spent the most time in many of the places where you were such as the issue with json Value not liking the bytes array and then URL encoding these bytes. I hope Codecrafters can improve on this, like maybe do not run the previous steps in their tests and pull in a create for URL encoding for bytes.

Please keep doing "impl" rust streams, you are fairly unique in this respect.

Now _that_ was an incredible livestream

You might like the "Dark Reader" FF extension ;) awesome content as always!

Please say you plan to continue this your videos and the way you break things down really helps me see alternative ways of doing stuff.. that said I think a quick refactoring of those calls in your main function would have really cleaned stuff up lol

For dark mode, you could add a CSS rule: `html, img, video, iframe { filter: invert(1) hue-rotate(180deg) }`
This inverts the whole page, and then reverts any images back to normal.
Easy to put in a bookmarklet:
`javascript:(function(){var s=document.createElement('style');s.innerText='html, img, video, iframe{filter:invert(1)

Nice, the replay is here! Couldn't be there during the live stream. Good topic.

[Dimkar]

the zero copy trick shown in this video seams very neat but it requires unsafe. I would love a video where you explore this type of optimizations and if/why they are ok and when.

[juchemz]

At one point you said that the fat pointer to you unsized struct stores the length of the last field, but the pointer to byte slice would contain the length of the entire thing, so I don't think your unsafe cast is valid. Though I would expect it to be off-by-8 not off-by-7. 😅

1:23 That's just sponsorship minus the good part of money 😂

[rodelias]

Great stream! Thanks a lot! Looking forward for part 2… 😅

[smallclover]

Looking forward to part two, if you make one!
