why? Before comments about LLM I didn't notice this. After I compared pre-LLM posts and post-LLM and looks like AI was used to write/edit this article. But.. why should I matter? Why my ignorance of this fact insane you?

sure, but solving conflicts is still hard in git. This can be simplified.

the one feature which I have never seen in VCS is ability to stick commit message not just to all changes, but specifically to line/hunk. It looks like very intuitive for me - I don't want to invent "references style" to say something about specific changed line in my commit - I want comment this line directly.

why? There is LSP support included. Pretty usable. Of course this is not fully IDE, but I don't expect this from "editor"

your words... > C++ implementations of defer are either really ugly

I agree with @pjmlp - you need to write wrappers around the C api.

But if you.. > If I'm gonna write RAII wrappers around every tiny little thing that I happen to need to call once

use them just once.. so, why care about ugliness, just write ugly code just once? Code can't be perfect.

if you do it once - why do you care about "ugly" scope_exit? btw, writing such wrappers is easy and does not require a lot of code.

yes, but not soo much as my production C++. I know that that's our choice, but I underline the difference between C and C++ here

Of course people do" virtual functions" in C, but I think this is not an argument despite C. I noticed that making virtual in C++ is sooo easy that people start abusing it. This making reading/understanding/debugging code much harder (especially if they mess this up with templates). And here C is a way - it allow but complicates "virtual". So, you will think twice before using it

I don't care because I use cmake

We live with that for *decades*. For me this is not a daily problem. So yes, this is not compelling, unfortunately.

do you publish dotfiles and scripts anywhere? I'm interested to see them

can someone explain security consideration of placing scripts into $HOME? Some time ago I moved all my scripts to /usr/local/bin, because I feel that this is better from security perspective.

not every. I have not lived in 90s at all, I am from the current millennium, but.. I am nostalgic about 90s. This is strange, but I feel nostalgia about times I never live

> Triangles are easy to rasterize

sure, rasterizing triangle is not so hard, but.. you know, rasterizing rectangle is far far easier

why use modules if PCH on your diagram is not much worse in compile times?

rust is not complex for C++ experts. Both have the same concepts. For beginners of course rust is harder, but that didn't mean bad for beginners

The user interface looks very similar to Niagara Launcher. I found it a really fresh and comfortable alternative to the default android launchers

> This is why other systems languages are taking off (besides the expressiveness or memory safety bandwagon) is because there are clear instructions in the docs on what this does with examples of how to use it properly.

I have never seen better documentation for programming languages than cppreference. Can you list such docs?

What are these 10% valid cases? Does someone have an example
