found your channel yesterday and have binged nearly every video, extremely entertaining content (even the ones on topics that i can just barely understand!) excited to learn more

Good video! Happy with the fact you went down into some of the nitty-gritty. Didn't expect going over error rates w.r.t. clock frequency, which was fun and not something I had really thought about (9600 baud goes brrrr). Only improvement would have been to cover more protocols, but there is only so much time in the world to make videos in :^)

hey man good to see u :) the dilemma is always about the length of the video; I have found overall if I make it too long and it's a very technical subject the retention is... mid at best. But fear not, as I mention I'm gonna do a separate vid on bluetooth low energy which is gonna be a blast. cheers!

@@hoff._world I very much look forward to that video. I remember doing a university module on the physical layer of wifi and bluetooth, the different modulation approaches, and the like. It didn't go massively in depth on the physics (I'm not an electrical engineer) but was very interesting regardless. So I will be very happy to see more of that. I assume it will be another overview of the protocol, as here? Any chance for going into using bluetooth le from the software side? Or a potential video on the software side of USB (implemented on a microcontroller?)

@hoff._world 4 ай бұрын

potentially, the only issue with covering it from software side with all these protocols is that the implementation changes depending on the platform, so for example if I were to demo BLE software on nordic chips for example it would have to be a video only about nordic chips... same if I covered the windows RT bluetooth apis, it's all very platform specific

Really nice summary video! I learned a bit about these in a microprocessors course in uni but always wanted to delve a little deeper into the topic, this was really helpful

hello, nice video! i know it might sound irrelevant but i have some questions. first i will give a little background. I'm currently learning C using the k&r ( i almost finished the pointers chapter) and i want to implement maybe a snake game using raylib after finishing the book. but honestly, i don't have any other idea. I'm not learning C because of any specific purpose and it is mostly because i want to know more deep stuff about computers so my idea is to start learning Go after doing the snake project because i really like Go and i'm really into network stuff( really want to know how protocols like TCP work and implement one of them). so what do you think? does it worth spending the time to learn another new language while i just finished something like C? ( of course i will use C to implement some personal projects, but i won't have a great focus on it as the main thing i do most of my time). one idea that i personally have is to learn go and try to use both Go and C in some projects( cryptography maybe). another question is that do you have any recommendation for someone who knows some C and wants to learn Go? i was thinking about buying a book( named "learning go") but i don't know if it really worth it(not money, mainly time), maybe i can search anything i need after learning the syntax?

the realisation you'll come to once you get to a certain skill in programming is that the basic concepts of programming and languages don't really change so much. Forgive me if I'm making a wrong assumption here but you seem like somewhat of a beginner, in that case my advice would be teach yourself programming using a language as a tool instead of having a mindset focused on "im learning X language". I'm quite comfortable with C and it took me a weekend to pick up and be comfortable with Go, it's quite an easy language to get a grip on if you are already good with programming concepts. no reason u cant do protocol/network stuff in C. In fact, I have hours of content dedicated to just that on this channel :) Focus on concepts, don't get caught up with languages. If you know C, use it to master programming concepts and you can swap languages like swapping a t-shirt.

@@hoff._world yes, i actually am a beginner. i just watched one of your videos titled "Getting good at programming" and i absolutely know what you're talking about now and thanks for the valuable advice. i think i will stick with C and check those network videos you've done, thanks for the content!

yayy new vid , alsi I want to learn more about creating custom network protocols....watched ur protocol video sensei but some concepts went over my head. Can you suggest me some books to read about it ?

@hoff._world 3 ай бұрын

my friend you simply need to come to the realisation that protocols can be whatever you want them to be. Seriously, sky's the limit. A protocol is simply a structure that the sender and recipient understand. You structure your data in some kinda way, you send it off, and as long as you program the receiver to understand it and do stuff with it that's all there is to it. Structuring the protocol is where there's some theory to it. There's 'best practices' and such, and there are plenty of protocols out there for you to use as examples like IP

@hoff._world 3 ай бұрын

@royalpotato4733 if you're more confident in other languages you can do protocol stuff in them no problem. In Python for instance there's bytearray you can use as an equivalent to uint8_t buffers in C.
