Alright, I'll bite, because you make some good points. Having reconsidered, I'm not entirely sure I'm in the right here anyway. > using bits undefined behavior intended to account for platform differences to actually disto

> Randomness hardware? There are already perfectly good PRNG routines available as used by currently available strong encryption. Yeah. How do you seed those with a good source of entropy? That's what RDRAND etc are for.

You're right, I misread and misinterpreted that! Thanks. Somehow I wasn't thinking and didn't realize that `t` aliases whatever was passed as `p`, and dereferencing a non int or char pointer would be undefined there.
754.
by PeCaN 11y ago
That'd still be defined though. It'd just be defined to set the first sizeof(int) bytes of `* p` to 1. ;) void * and (char * ) can alias to anything and the compiler has to make it work. Of course if you pass a pointer to a type s

Yes, but note that the assignment occurs after the NULL check. If the grandparent did mean to put it before, then the code snippet would be undefined, but it wouldn't be surprising either.

I'm gonna rant for a bit. I see posts like this from time-to-time, and while they're certainly well-meaning there's a good reason why you're not writing the C standard. :-) > compiler writers take unjustified libertie

Sometimes he does quite good in-depth articles (such as his Talos Workstation preliminary benchmarks[1]) but mostly it's a nice site to avoid having to scour mailing lists to hear about cool new stuff. 1. http://www.phoronix

Well, for one thing, it's not offensive. Attacking minorities, genders, and/or sexual preferences can be offensive. A popup calling out Debian on their ridiculous version lag is not. So... who cares, really.

GreenArrays's main claim to fame is that it's a fully asynchronous architecture (no central clock). Oh, and it's from Chuck Moore (the Forth guy and kinda the Mike Pall of hardware design). I had no idea Lens targets it. That

It doesn't. How does Apple's A9X compare to a Xeon E7? RISC-V is excellent for hobbyist boards, mobile CPUs, high-efficiency low-performance servers, as a base for DSPs, high-efficiency network equipment, etc. Everything from the

Yeah, if only there was a well-supported open-source OS that is generally regarded as reasonably secure and has been ported to pretty much everything under the sun. It would be nice if it ran the GNU userland for easy development and had a

I'd debate that a bit. Personally I hardly had to ask any questions when I was a beginner, and I'm not even particularly good with Google. Relevant vocabulary can be picked up from tutorials quite quickly. Though Google does seem

Because they're usually poorly phrased with no effort put into them at all and generally it's fairly clear the asker hasn't even checked if the question is asked before. All the basic questions have pretty much been answered

Disabling JS on mobile is a godsend though. I keep JS disabled on my phone[1] most of the time and it's generally just a more pleasant experience. I don't even have a particularly slow phone (HTC One M8, I guess it's a couple

To the best of my knowledge, VIA CPUs have no secure boot, management engine, or any other proprietary secondary hardware. Coreboot supports many VIA CPUs and motherboards[1], though it's unclear if it uses any binary blobs the FSF see

I run it as a desktop OS on a Lenovo G700 and those all work fine. Hardware support isn't as complete as Linux but it isn't bad at all either. Chances are anything that's older than 2-3 years will work out of the box, anythin

PS3 did—I believe PS4 is not nearly as heavily modified[1]. It is certainly locked down though, at least after the early PS3s where you could, say, install Linux and build a HPC cluster[2]. 1. Mostly from people who've hacked it; http

What would they gain though? NT is a pretty good kernel with very broad hardware support. If anything, they'd just make NT fully POSIX-compliant. They'd get the same benefit with a fraction of the effort of porting Windows-the-GUI

Yeah, I want to develop for WSL from Visual C++ on Linux running under WSL. ...What a time to be alive. Did hell freeze over or something?

Hm, but GNU/Windows still implies usage of many non-free binary blobs bundles as drivers with the OS. I advocate stripping them out and terming it GNU/NT, affectionately referred to as "Gnewt".

They've had a POSIX subsystem (SUA) for a while, but it's kind of ancient. I assume they resurrected it and implemented some Linux-specific APIs, which would actually be SO COOL.
