Thank you so much! I definitely need to spend some time reading the README. There are so many things I'm missing. :D

Python is always the problem. It's load bearing. I just broke my Linux yet again because it is a Debian and I tried to update libinput because of python, it refused and updated python3 back to match it. (to be fair, I did random pokery with dpkg) Why do we have DLL hell in Linux in 2023. Is that Windows XP ? maybe it's my fault for using Debian, maybe Debian is stable bugs forever. Maybe Linux can't afford having a SxS and becoming a 30GB OS only because I wanted to have 2 versions of libinput. Maybe I should just nuke everything and make my own Linux from scratch instead. Anyway it's my fault for using Linux to begin with, or wanting to use KDE with Wayland. Also, Clang17 needs an Old GCC10 to run. Why, why. Sometimes I think Windows is better because I don't suffer too much trying to change things and I can't see how bad and shit the code is, so I don't try to fix it. It's all Python's fault. Why can Debian have 4 different versions of Python3 at base. Why's every thing hanging on libinput, is like libC of KDE. Why does the thing that loads shite into the D-bus from the server side needs to be the same as the shite from the KDE/QT side, never mind I don't want to know, maybe they're sharing binary data and pointers. Anyway , sorry for the rant. And it's python fault , it's all pythons fault .

Well you are watching an actual artist.

Who comments on comments?

As per the LFS installation manual: "To compile a compiler, you will need a compiler."

C is written in C and Java is written is Java, and many other languages is written in itself. Eventhough it's understandable, still sounds fascinating 😄

​@@ace5331the Java std library is written in Java, but the JVM is in C++. An interpreted language can not be self hosted. You could run the Java JVM in the C++ JVM, but then you would have to maintain 2 versions, so it would be pointless.

I was just typing this coment and saw this

it made my brain go smooth

I certainly do. It means my IDE _and_ debugger uses the same interface. The seamlessness is amazing. I use RR, GDB seamlessly together in vs code with the Midas extension. It means all my bookmarking, all my navigation of the code works identically. It makes the process of development exponentially a lot faster than having to manage multiple UI:s for what essentially amounts to the same work flow.

Tbh, I got really lucky today. It's def not always like that. :D

Sounds like you're just a 0.2x developer. Skill issue

did i just get spoiled in a "debugging the debugger" video

lol, and there's your moment. Actually I think it's because in Python 2, print is a keyword, not a function. So the parentheses that would normally indicate a function call are instead interpreted as a tuple, because it contains comma separated values. Changing it to a single string value just makes the outer parentheses redundant, but that also makes it compatible with both versions.

Maybe it's just because parsing algebraic expressions with the proper order of operations is a natural part of generating an abstract syntax tree. Usually, function calls and control flow take lower precedence than algebraic expressions, so you can just take your expression parser and add those things on the end. Of course you can also use a parser generator like Lex and Yacc to describe your language using pattern matching, kind of like regular expressions.

There is a single-element tuple, but its syntax looks like: (5,)

@@odomobo thanks for correcting me, I'm still learning Python Out of curiosity, what's the use case for single element tuple?

@@vuongnh0607l I don't think there are many use cases, as I think it's mostly there for consistency's sake (so you can create any length of tuple). I don't write a lot of python, so I've never run into a situation where I needed to use it, I just thought it was interesting that it does exist

ikr? this has to be one of the w̶o̶r̶s̶t̶ most curseds C++ codebase ive ever seen. i bet this was written by people who thinks C++ is C with classes, i mean, you can clearly see it, they even manage the memory themselves by hand. imagine doing that in 2023.

@@apenaswelligntonwhat do you suggest?

you meant the best C++ codebase

@@djscratchcat474simply use what the standard already offers to you. theres barely any reason to come up with generic containers from scratch, and if you do try to come up with one theres a big chance you will get it wrong

lol 3 seconds later you figured this python2 vs python3 bug out lmfao

Hi Tsoding developed a 3D graphics library from scratch, where he goes over the mathematics behind rendering objects in 3D. kzfaq.info/sun/PLpM-Dvs8t0Va-Gb0Dp4d9t8yvNFHaKH6N Maybe some of the episodes in there relating to 3D will be useful for you.

In python 2, print was a builtin keyword, and in python 3 it became a function. Since it's a keyword in python2, you don't use parens when calling it. However, if you use parens anyhow, the expression on the right becomes a tuple, and the tuple is printed.

You start with writing machine code by hand to create an assembler to assemble a compiler to compile a better compiler :) It's the compilation centipede.

@@andrejsk6211 ya

Thanks. Watching this video I was trying to remember what was the name of the graphical frontend I used to use lotta years ago. I never realised it was GNU's own frontend. Gotta love the aesthetics of Motif :).

You're seriously calling an explicitly recreational programming session a waste of time...? Recreational programming that also happens to improve upon a piece of OSS. A piece of OSS he actually likes, at that. Are you just e-peening? Are you simply a bit of a twat? What am I missing?

&arr[0] is most likely a LEA instruction on x86. It doesn't try to access the memory of the array, just computes the address of the 0th element. During the compilation process, in an abstract sense, arr[0] is an l-value on its own, which you then take the address of. But the expression as a whole only has to produce an address, not the value at that address, so there's no reason to MOV anything there or use that memory as an operand, unless you do exactly that.

@@DFPercush truly. But this seems not portable 😄

@@alurma Try it on godbolt on an arm or mips cpu. The operator overload is the only reason it would access the array. But if you want to be safe, you can also just pass the array variable itself, which will decay to a pointer in C. In C++ it will also decay to a pointer, unless you're calling a template function that expects a reference to an array of size , but in that case the size will be known and one would hope it wouldn't try to dereference out of bounds elements. Sorry if I'm making it too complicated. Fun fact: in VB6 if you wanted to call a C library (including DirectX) and pass it an array, you had to pass array[0] because it passed everything by reference, so array[0] is how you got the address of the beginning of the array. That was the only way to do it. I'm not sure I ever tried to pass an empty array though.

@@DFPercush yea, the usual "passing array so it decays to a pointer" seems simpler :) Interesting comment on VB6 :)
