A lot of affordable machines a few years old even had 4M. I remember my dad upgraded from 4 to 8 and from Win3.11 to Win95. The computer had maybe 1 or 2 years, hardly more. It was around 1500€ (well, it was 10000 FRF at the time) when boug

Cutler certainly did not write the whole first kernel alone, although the initial size of the NT team was quite small, at least at the very beginning. The story of the development (until the at least the first release, IIRC) is in the book

I just checked and both of my benchs were done with Defender. When I disable it, it is down to ~0.5s I would not build a Linux kernel here instead of in a VM, but for tons of things, this is very usable.

Well in the end we are using any X rather than Y tech because of manpower, regardless of pretty much any other characteristics. So let's put manpower kind of aside for the bulk of the dev (where thousands of man-years are needed for an

About shared libraries, I know that there is this line of thought considering them "evil" (well at least sufficiently to want to get rid of them); but I'm quite unsure about what a modern system would look like without them (

You want to ditch shared libraries and mmap to map your big processes using GB pages to make fork fast again (despite it not being the main and only drawback)??? OS research might be relevant, and it's good that some people have wild i

On 1803 and 1903 it's 3 to 4 times faster than MsysGit (WSL is ~1s on my laptops). It is possibly slightly faster on 1903 as my laptop running it is faster than the other for this bench, despite having an older processor. Now in a Linu

That's always a possibility and there are others. Many people found that whole class of possibilities not especially interesting, because they are falling on the irrefutable slope; if there is a "god" that absolutely can not

I don't see why JO would be any different from other Jcc, especially since JL is SF ≠ OF. Maybe you were thinking of the problem with INC/DEC and CF, but even then that's a problem of INC/DEC, not of Jcc.

IIRC Notepad source code is in a Windows SDK. Probably an old one, but it only started to be actively maintained quite recently (and even then: only very lightly), so the source code you can get will likely cover most of its lifespan for no

And it would actually change the historical and current behavior of exec returning ENOEXEC for 0 bytes executables (see also https://news.ycombinator.com/item?id=19081124 ) . So I am changing my mind: a binary true is bette

by temac 8y ago
Oh it is not nearly as good as I thought then. I actually tested it and zero byte exec still make exec() returns ENOEXEC on Linux. So a small binary is definitively more versatile...

by temac 8y ago
It would be a valid approach but it is less elegant and harder to maintain. Probably the kernel could special case 0 bytes executables, if you really want to optimize the scripted truth.

by temac 8y ago
true once was, and IMO should be again, implemented as a 0 bytes executable. Since then, it has infinitely bloated on most systems. It actually began at AT&T, where they apparently decided to copyright the trueness. From there it went d

Tons of people have already interpreted that it is ready, and some of them have died. Maybe they are to blame. But for practical reason, I don't care much. I interpret Tesla's communication as highly misleading, for the very simpl

As far as I know Win NT threads are 1:1. Not even sure how it would work or even make any sense to have N:M handled by the kernel. N:M is usually a mainly a userspace thing. And Windows is even less likely to use that kind of convolution, b

hm is NT a purer Unix than Unix then? After all, it has all its object in a filesystem-like tree...

But is the fallback path for production even correctly tested, then? And if it is, then what becomes the point of the assertion?

If you have a fancy "USB" port which allows connexion of graphics cards (so basically a PCIe port, although it also accepts USB), chances are that you can do whatever you want with unrestricted DMA through this port. It seems that

If the effects are merely limited to a widget behaving weirdly, this is a sound strategy. And this seems to be the case for front-end code in well designed systems.

by temac 8y ago
So assertAndContinue makes no sense, right? On my side I don't really see its point anyway. If the code is actually ready to handle such failures, this is merely an error trace, so it should just be called that.

I'm not sure even sure they will ever change it. It was designed for Vista using a security model that now corresponds to the "always ask" setting, and hastily changed to propose the two other settings for Windows 7 because u

Engineering, especially at this level, is not supposed to work like that. You certainly not do dev proto, then switch to prod both in one step and without even rechecking the tests you did on the proto. So their official explanation might

Today a graphic chip is also good to compute ultrasound images. I suspect that you can even do it on a CPU. I'm not sure if it is that practical to process in a FPGA if you want to compute non-potato image quality: you would need to
