Yeah, I'm so sick of hearing "it's way faster to install app on linux by using terminal than using that bloated gui softare center".

In my company it's a bit more complicated, but I have the spirit of your thoughts. I think business software (such as the ERP-like software I work on) is often an entropy magnet from the complexity point of view. It doesn't strive

Yeah, same thoughts. And this industry is becoming so volatile, I'm not sure what will happen tomorrow. I mean it's highly unlikely that AI will replace developers at least in the next 10 years, but I'm not sure what will &qu

Even before LLMs ORMs are good enough to cover most of the use cases. Only some complicated use cases needs raw SQL. So you can use both.

by senfiaj 3mo ago
What's the problem with using ORMs for 95% of the cases and using raw SQL only for the remaining 5% where ORM isn't sufficient? One important benefit (aside from writing less code) of ORMs is type checking which is important for

Yes, that was my point. But Windows might still allocate pages lazily (i.e. reserve them and actually allocate only when the program writes into them). The difference from Linux is that it will only reserve if the allocation has a reasonabl

Well, if Firefox also works on other OSes, it probably should gracefully handle failing allocations, isn't it?

So it's a footgun because a lot of low quality software?

But why wouldn't have happened with Rust? Sorry I can't find anything about Rust in the article. Or you mean if the Linux kernel was written in Rust and that stupid bool coercion was not possible?
47.
by senfiaj 3mo ago
There was also a bug in the Linux kernel, or did I miss something?
48.
by senfiaj 3mo ago
As I understand, Windows can also lazily allocate pages, but it does after making sure the memory budget is adequate in a case of low physical RAM pressure and is guaranteed to be backed up by a page. But yeah, Linux approach is really slop
49.
by senfiaj 3mo ago
I think Windows doesn't do OOM kill, it just fails fast for unreasonably large memory allocations. If the allocation is succeeds, the committed virtual pages are backed up (or more precisely guaranteed to be backed up) by a page file.
50.
by senfiaj 3mo ago
I think Windows also uses something similar to Linux memory overcommit (maybe call it "lazy page allocation"), but probably all the available virtual memory is backed by the page file, the OS has limit for the allocation size and

Well, they might still do it but less aggressively. For example, only when using MS Store or only some specific services. Apple uses a similar strategy with MacOS. Online accounts can also be convenient with with service integrations, provi

>> Windows 11 requiring TPM, Secure Boot and being all react wasn't great. For me a bigger concern is that Windows 11 requires MS account, and making harder and harder to bypass it. This is a disrespect for my freedom and privacy

The source, conventions are quite similar to Linux. So, probably some level of POSIX compliance + reusing standard libraries (such as mlibc) helped a lot.

Cool. I also had similar idea: https://github.com/surenenfiajyan/3d.js . But your one looks richer in features.

If I'm not mistaken 286's protected mode wasn't really that popular because it breaks real mode DOS programs. Meanwhile, 386's 32-bit protected mode with paging and virtual 8086 mode was a big success.

>> In 2026, we have to worry the a discontiguous memory space looks flat. Well, there are large/huge pages (2MiB/4MiB/1GiB) that reduce this problem.

by senfiaj 4mo ago
Maybe (I think it's possible in protected mode), but it still has an allocation problem, imagine there are programs A, B, C in the memory. Later, A and C are unloaded, leaving 2 free holes, totaling in 2MB. Now you want to load a 2MB p
