When I stumbled upon one of your videos couple of months ago i thought that i dont understand anything this weird russian nerd is talking about and closed it. Now i gave this another chance and know i am like i have no idea what this weird russian nerd is saying BUT man you are funny as hell. Also i learned so much new stuff so thank you a lot for your work. Still need to watch the rest hour of the video cause i use it for falling asleep but i promise i will finish it. Also liked and subscribed. Keep it up man - you are amazing!

[@nickmoore5105]

Perfect falling asleep stream. Interesting enough to distract you from your thoughts. Boring enough not to keep you awake. Consistent tone and volume. Long enough that it doesn’t run out before you fall asleep.

[@givememoJo]

@ you and I my friend are on the exact same page. Also his accent has the perfect balance between not being annoying like some random Indian PowerPoint video uploaded 6 years ago with 1510 views but also not too mild for me as a none native speaker to focus too hard on the actual speaking. Really a great mix. With that being said, I will try to fall asleep now

that tcp implementation video will be one for the ages, was doomscrolling last night and stopped to watch this and didn't realize where an hour went

[@grenadier4702]

31:32 I don't think that's the case. I think VPN service detects that an IP is one of the private addresses, thus it just disables itself and sends a normal request, otherwise I don't see how it could be able to send a request to your private IP address because basically VPN service sends a request, in your case, to the German server providing in the payload the actual address that you wish to request, but if you provide a private IP address, then how would VPN be able to figure out what to request?

Flush means read all the remaining bytes in the buffer. Always flush before close.

[@dnkreative]

The phrasing "program reported that all the data had been sent correctly" is wrong. Succesfull write to the socket does not mean that it was sucesfully received or even transmitted to the other end.

[@ZZ-sn7li]

It's literally saying that data has been SENT. Not received.

[@weekipi5813]

minute 1:48 read blocks because probably browsers keep a single connection alive for handling multiple requests efficiently. I would like to consider your current implementation of reading the client request. You're implementation suffers from potentially reading parts of the request body while reading and checking the individual chunks for the recurrence of double . You should probably seek and then read like you did last time with websockets

[@alh-xj6gt]

At the 90 minute mark on C. I don't like it either but it is simple and it is ported to everywhere. We could ditch it for FASM but my brain is too smol for fasm I need type checking and a compiler to hold my hand. I'm amazed seeing what people manage to make in assembler like KolibriOS and MenuetOS. The templating simplicity. Everything escaped and powerful as good old C is just usable. I guess if '%' is needed it need escaping? Need to watch the tore vid. This is just again such a nice show of "more with less" what a flex. such awesome much inspiring.

[@TasosDaris]

If you use openvpn, I believe the default configuration for client/server is to communicate via UDP (openvpn assumes that if UDP fails to deliver, your underlying TCP connection will retransmit). I'm not sure if this could affect the communication of a and b.

I didn't watch the whole video (2:20 ? wtf ? I have a life to live), but in my experience of some decades programming TCP (I still do it today), shutdown is generally not required before a close ... I *never* use shutdown before a close also, applications need to implement their own protocol over TCP, to better avoid losing data and one more thing: most people *don't* understand SO_LINGER, and use it to avoid losing data, tough it makes losing data more likely!

There are instances where sizeof requires parentheses, so for consistency I always use them, but I also think it just looks better to use them anyway. If it were a property of objects in the language, like say foo.sizeof then I'd be fine with not using them, but using it like a function it just looks weird to not use parens. I've never felt the need for a defer in C, and partly that's down to my habit of writing a matched close/dealloc for every open/alloc of a resource right from the start and just inserting new lines of code between them, just like I do for braces, but also because I'd much rather have RAII than defer. Of course, if you really feel it necessary, you could always write your own with macros and helper functions and of course define return as some sort of defer_return. I've got a partially complete implementation with setjmp/longjmp and a static array of callback functions, but it really would be better if it was supported by the compiler, whether it be defer or the superior RAII. To the chatters that said C++ fixed pointers with references, I would say they also broke references by differentiating between r-value and l-value references. I get why they had to, but I feel like that should've been designed differently even if it would break existing code. Your trouble with referring to your own function as start_with versus starts_with makes me think that someone should issue a PR for changing end_with to ends_with in nob. The issue you had with a do/while loop not being able to see a variable that was declared in the inner scope of the loop actually makes sense, and for C that won't change without a potentially breaking change to the standard. For my own language, I chose to leak inner variables if they're used in the header of a loop as long as they don't shadow an outer variable. It gets a bit dicey when you're dealing with iteration in a for loop, but I feel like it was the right choice for a few reasons, not the least of which was clarity where obvious over verbosity. One thing I did notice in this project was that you have an awful lot of append calls when you could just use the standard adjacent string concatenation. Of course it's kind of annoying to have to break up a string in the middle for a formatting operation, but I feel like it'd get rid of a lot of noise in the code if you grouped as many as you can. This is perhaps another reason why I like f-strings, because you don't need a formatting function or a call to sprintf or printf, just stick the variable right in there.

[@Spongman]

the bit about HTTP is wrong. HTTP supports sending non-keep-alive responses without chunking and without a Content-Length header. the implied length of the response body is determined purely from the remaining length of the TCP stream. this is so you can stream responses slowly back to the client without having to do chunking. HTTP servers that don't shutdown() their sockets correctly are in error for this reason.
