"Remember the code is more scared of you than you are scared of the code" - Zozin 2024
I mean, the code doesn't crash you, you cŕash the code...
Looks like we're alive.
He is alive and well, active on twitch and discord :D
that "i can't even spell 'world' anymore, i haven't programmed in C for a while" caught me off guard
I think the main reason people love Lua is because of how incredibly simple, yet powerful it is (Same reason people like C, but it's a scripting language, so in a different way).
The only structural data type in it is a table. Want arrays? Use integers as keys. Want an object? Use field names. Want a dictionary? Use whatever you want as the key.
Want to access something that doesn't exist? It's nil. Want to delete something? Set it to nil. Applies to both fields in tables and variables.
The syntax is minimal. No need for semicolons OR newlines, because it is always possible to infer where statement separation occurs. There are only 21 keywords, which is mostly control flow and primitive values.
Want more power? That's what metatables are for. Use them to add operator overloading to your tables. Or use them to implement inheritance.
The compiler/interpreter itself is also deliberately simple. It is a single pass compiler, written in pure ANSI C (Except for dynamic linking, but for embedding it is an understandable compromise), very fast and small (One of the fastest scripting languages), because it was designed to be embeddable.
Reading the lua manual really gives the feeling of "we want the most power with the fewest features." It doesn't have traits I look for in a "real" language, but it's inspiring as a different perspective designed with a different use case than the mindset I usually work with.
This is actually one of the best comments I’ve read describing why I find Lua so enjoyable thank you for this. I might steal it later
I switched over from Lua to Janet recently because it brings the mindset of Lua to a Lisp syntax, without the compromises of Fennel or the baggage of CL/Scheme systems. And it's more fleshed out as a standalone scripting system, which ended up being "bolted on" to Lua with Luarocks, and I've never been happy with how that worked. It takes a little while to get comfortable with the idioms specific to Janet, but I'm finding it cozy enough.
Edit: Also, if we are after minimalism, Forth is a decent scripting environment for gluing together chunks of assembly, and probably enough for this usecase.
Metatables and coroutines elevates Lua to S-tier power. Also small and fast enough to run on a GameBoy Advance. Love Lua.
Honestly i descovered lua writing my neovim config, and yeah it's a very interesting language.
It's nice that it's not polluted with 69 ways to do the same thing (cough cough c++ cough cough)
I want a full song from "Can you Rust doooo thaaaat ? i don't think soooo"
The commentary on Stack Overflow alone makes this worth watching.
Starting at about 1:52:10 :-)
"Remember - code is afraid of you more than you are afraid of code" - I really like this quote, until they start using it on dogs.
Tosding the gordon ramsy of C programming 🤣🤣
I'm excited to see what primitives you decide to use. I know that the what makes manim good is the choice of primitives, I'm assuming the same needs to happen with this library considering its a programming viz and not just a viz.
You can do all of this in Assembly if you know what you are doing. C/C++ just makes assembly much easier and more streamlined as they automate a bunch of repetitive tasks for you behind the scenes. You don't have to setup and tear down all the registers for the stack frame, you don't have to manage the stack pointer for every routine call, you don't have to query or access the hardware or interrupts directly, you don't have to manage the memory at the hardware level and worry about v-table entries, and so on. You don't have to worry about which register your return value is in, checking the flags for the conditions of all of your operations, the branch predictor, etc. Assembly is architect independent, machine specific and isn't really portable. Yet you can still do all of this in Assembly if you know what you are doing. It's not about this language or that, it's about your understanding of the hardware and how the software operates it. At the end of the day, it's a skill issue based on your level of understanding and knowledge of the system you are interfacing with.
Bro, making a graphics library by raw dogging assembly???? Please stop, you're giving me new nightmares to wake up to
I made my own engine almost 2 years ago for my grad project. I used ffmpeg and nodejs child process and my own graphics library written in JS. Which gives me a massive success in grad result. Its even 3 times faster than manim ❤
hi, i am looking for inspiration for my grad project and this graphic stuff is really interesting.
how difficult was it and did you do it by yourself or with a group?
it's hard to find a topic interesting but also not too difficult to scare people away, because we have to do it with a group.
Honestly, AI is not much better. Google's AI would refuse to give information on C/C++ functions to minors because the functions were tagged "unsafe"
For programming the animation itself maybe an immediate mode style api would be nice. Instead of having to build an array of keyframes. Which are going to be a pain to change on a hot reload. If you don't mind borrowing from sebastian lague's animation setup.
That is you have a function that gets called every frame and it then does things like float t = interval(a, 5); which returns a value from 0 to 1 depending on where in the animation you are. Then the next time you call interval(a, 3) the effective interval starts after the previous one finished. And it uses the t to render an animation.
To facilitate this you would need a float animTime; and a float currentTime; in Animation where animTime gets updated based on the input into interval() and currentTime is the time you are visualizing. So the return value becomes return remapAndClamp(currentTime, animTime, animTime + period, 0, 1)
You can apply ease-in and out on the returned t if needed.
I like where this is going, tsoding!
17:20 Skia is a giant Google bloatware for drawing shapes that's like 600megs of source
you're actually reinvented erlang's hot code reload approach with your plugin system. take a look at those ideas, it is really cool when the entire system upgrades with no restart
I think Tsoding programs in a Hyperbolic Time Chamber.
Lol perfect illustration of SO answer
New tsoding vid, let’s goooooo!!
Hi, Panim playlist link broken
Have a nice day
Thank you! Fixed!
the *worst* part of function pointer declaration is that it was done "on purpose". there is a special case in the parser to handle that ugly syntax IIRC.
If I have to use a dynamic language, for any number of reasons, I'd want it to be Lua. I love it for the semantics, definitely not the syntax haha. Otherwise, yes I'd also prefer statically typed compiled languages.
Is 3b1b parent of R2D2?
Its 3*blue*1*brown* another channel that does explanatory math videos

Mr Zozins explanations are the best imo, probably would become a great teacher if he wished to
Macro source is as unreadable in C as it is in Rust.

Thank you....
the captions seem to be a chat playback for some reason!
Best animation for loot boxes in game 😂
Skia is a graphics library from Google, it has a lot of handy bindings ... in Csharp for example ... raylib is way cooler though 🙂
the pascal case function names are so clear, what is this font?

LOVE YOUR VIDEOS
The Panim Playlist link is not working :(
28:53 I don't know why people ignore the gcc "-fanalyzer" option which gives A LOT more warning and would, for example here, clearly give a warning for a segfault.
It's annoying n slow. Surprisingly cl /analyze is pretty good!
@@multicoloredwiz annoying ? To have warnings that help you not crash your program ?
And obviously it's slower. It's a tradeoff as always in programming. The most important thing is that you can choose between safety and speed which is the power of C (while rust fans will brag about the safety and then compile for 10min).
@@lordeji655 I agree with you on all points I'm just answering ur question
@@multicoloredwiz AH sorry x)
2:02:53 Why do you use memset/memcpy for struct instead of assignment? Is this a C thing? I think C does support struct assignment. As a C++ programmer, this is absolutely bizarre.
what are programming socks , i had not found them in whole market.
How is Twitch Chat caption even possible? 🤔
I haven't uploaded a single video on yt so it might be easy. Is it that you can export stream chat as transcript ?
you can read the chat with the API, so it should just be a matter of storing the comments with their timestamps and then converting that to a transcript track
@@yjlom
Yeah that makes sense
I love you.
Bruh, what font is this. Sweet

Why captions are just Twitch Chat. Is that a mistake?

Great 🎉
mm nice
Seeing you use macros all over the place gives me aneurysms, as a C++ programmer. I guess this is what "production" C looks like because you need generics and meta-programming in large projects. In C++ using templates (with concepts) and function overloading helps you achieve this (along with little bit of constexpr).
You said you are not a fan of "dynamic" languages. Here C is no better than those dynamic languages. Whereas in C++ most (generic programming) errors would be caught at compile time and the usage of static_asserts and concepts make those errors easy to reason about.
44:04 It's embarrassing to see this dude. This function macro, in C++, could have been a simple function template (with appropriate constraints).
C++ template metaprogramming is the embarassing thing
WHERE RED CAR???
you mean twitch.tuvalu right? right?
