ReDress

I'm obviously not going to discuss this argument further.

Trying to counter a logical argument with a technical argument is pretty lame and doesn't make for a healthy conversation.

io-uring is great for this.

However, I am bit skeptical as to whether io-uring will ever support all Linux syscalls.

At this point I am convinced that io-uring primarily supports I/O API / syscalls. That would mean syscalls relating to disk and network I/O. While this covers a lot of syscalls it most definitely doesn't cover all.

Though, to give some credit her, it does also cover to syscalls relating to kernel features like futex but yeah, for the most part it doesn't cover much that doesn't have to do with I/O.

Which is obviously not a problem but raises the question of whether it ever will support other kernel features.

I'm just noting this because it makes the number of Linux syscalls seem very exaggerated at a whole around 400 syscalls.

But, anyways, not like it matters that much but still.

400 distinct syscalls is a very large number of syscalls if you generally presume they're entirely distinct.

If syscalls are so similar, for instance, like 'read' and 'readv' or 'pread', 'sendmsg' and 'sendmsgv' or 'fork' and 'vfork'.

Does it still make sense to term or classify them as two distinct syscalls?

It's when I wrote some code at work. I couldn't easily complete the task. Each day I go to work and write even more code. The task is far from complete. I have written hundreds of thousands of code so far.

I seem to be closing in the completing the task nowadays, though.

It has been 5 years so far.

Looks like Qt Creator after all.

I bet it's a lot of fun being a Rust programmer / coder.

well, if we go by the title then I would expect that he's writing the code on a piece of paper and not typing into a computer - heh

But, okay, that could make a valid excuse.

But, what you cannot excuse yourself for, is that you don't really add any functionality. In fact, you don't reproduce all the functionality let alone adding more.

I just looked at the first example / utility he implemented; which was 'touch'

Will this actually update the 'last modified' date for an already existing file?

Also, there's a standard way of processing command line arguments on Linux/Unix, which is not being followed here.

I fail to understand / find the gist of this article.

Article describes the technical aspects of the bug, how it got handled by different vendors...AI position on it...

But, one would always ask themselves, why did the author write this article? That part hasn't been clear to me even after going through much of the article.

Aren't C++ templates the desktop version of macros?

Unless I am mistaken macros have been around for ages and are available in many many languages.

Is this possible that you could give me some example project, for instance, that makes of C imperatively?

Probably depends on at what level you see things. If you visit and probably live in Japan, then you develop the concept of 'cryptocurrency'. You then subsequently develop intellectual property around the 'concept' of 'cryptocurrency'.

Is this really 'imperative' programming? I'd say not but depending on at what level you see things, then it could be.

At project level, then it's purely functional.

If I write my code primarily in a way that is simply supposed to achieve functionality then it's by definition functional programming.

Regardless of the language used!

AFAIK, I could be wrong or ill informed about this.

But, Rust does indeed embedded extra code for much of the functionality that it adds ontop of what C/C++ has.

This obviously has a performance hit. Might not be observable on a desktop application but it will be evident on server applications.

AFAIK, functional programming is programming that doesn't modify state.

And, if all you're doing is taking material from real life and uploading into computers, then you're not modifying state at all.

Problem still persists where OBS cannot capture it's own window.

Just when I moved over into a VPN, now the broader network / internet is looking more welcoming - heh

It's an interesting question, especially considering that reports keeps coming up of AI having engaged in activities that could demonstrate lack of good intent.

But, yeah and indeed, it probably takes more than just technical abilities to start a company.

As much as I am concerned. Security is not a concern in most open source projects.

But, for one reason the other, they might give credit to a vulnerability they find interesting.

I don't think AI is of much concern, if you actually have a valid security issue.

No-one, really will care if you discovered it via AI or otherwise. Because, the weight of the bug itself should outweight other concerns. This is how professional security works. There will always be one concern or the other about a bug but what carries more weight will determine the direction that the disclosure process takes.

A valid security bug, by itself should carry enough technical weight that concerns about whether it was discovered through AI or otherwise should become irrelevant.

Anyways, it mostly seems like people don't really care much about computer security at Linux. I would like to think they care more about infrastructure and related security issues because, well, if my computer is an open book, then why would security issues around it be a concern?

Anyways...

Enough said here - lol

SMB was "imported" into the kernel as an optimization for the user-space version - heh

To be honest and fair, in this situation I don't believe this is something accidental.

It probably just happens that the security concerns at ZDI don't match the security concerns at Linux(the vendor).

So, it turns out that this vendor is difficult to work with ....

I mean - heh

I'm not surprised because the disclosure process of https://hackerone.com is completely and openly public.

But they have also disabled Linux as one of the products that they work with.

This is great, this is some good work. But, like an issue I described before with Linux kernel io-uring[1], this fails to test and demonstrate performance with a healthy server load.

This obviously fails to depict a healthy server load because it's just way too specific.

Probably because C and C++ are mostly used in system and desktop development.

Rust is taking steps or has been taking steps in this direction too.

It's not surprising that a lot of experienced systems and desktop development engineers looking to getting their hands on the newest tool already have experience or at least familiarity with C and C++.

I'm going to go out on a limb here and make a wild guess.

That boolean is actually mostly an extension of the integer system whereby we now have an integer type that stores only one bit.

Whereby the bit stored either results in a 'true' or 'false' value.

Anyways, I know booleans are useful in systems development when you have strict memory / storage constrains / bandwidth (networks).

Yeah, that works for me.

I'm going to project here. Please don't negvouch. I know I am projecting here.

I'd like to note that it seems your life at a computer mostly revolves around Emacs and emacs only.

This doesn't sound sane to me. And you should probably try to diversity when it comes to your engagement with your computer.

The whole computer is supposed to provide you with an ecosystem but Emacs just by itself will not provide you with a whole ecosystem in which you can trive in.

My apologies for this "insane" comment.

I feel there's a general conflict in what exactly to quantify as 'art'.

At least at professional level, art is developed with a purpose / objective / intended function. For instance, I might visit Africa as someone who has living in Europe all my life but when I go back to Europe, then I decide, well. I should probably put some of what I saw and experienced in Africa in writing or drawings. The above scenerio is quite different from someone who generally draws and writes for leisure.

This is something that happens a lot and happens to apply in all sorts of trades. The situation is often that I engaged or experienced something in real life and would want to express the experience in digital form or some other form.

That said, this conflicts with the general idea of 'art' and other disciplines like 'philosophy' which are generally considered as things that people do for leisure.

Just making some general comment here :-)

Oh, well.

For as the primary functionality of your local computer is as a desktop then you do indeed need to be running a server(be it a VPS, dedicated server or whatever).

Otherwise, then I would ask the question? What do you use your local computer for? Playing games? Sounds childish

The bottomline will remain, there's functionality you can get from a $5/month VPS that you can never get out of a desktop. Do I really need to list them? Probably not because they're too obvious. I mean, a server gives you access to the internet.

But, anyways, I forget servers are not useful anymore because we have all move to the AI protocol :-)

>I'm absolutely stuck on your comment that trees are the wrong approach, or that trees are somehow incompatible with precedence. They encode the precedence more explicitly and unambiguously than the original string itself. Trees being incompatible with precedence is like parentheses being incompatible with precedence.

IMO, trees are not incompatible with precedence but I just prefer a more barebones approach to this fairly simple problem.

>The code to create the tree should not complex, so yes, AI could be used, but most competent coders should be able to create a basic version and test it in an afternoon.

I generally tend to find the idea of 'competent' coders misleading. For the most part, I have been developing or writing code in a certain language for while, then it turns out that I am competent coder? Because, yeah, I've been using C or Python for a while and can easily solve a lot of "complex" problems in C but with all due respect, I am obviously not a competent coder. It's like a situation where you frequent a certain part of town that you're very familiar with it and the people living there but then at the same time you don't live there - lol.

Anyways, for this problem I would parse this statement but definitely not into a tree. I'd assign the integrals to objects. I would then parse or go through the statement again executing the operands.

Well...
