"Common Clause" prevents everybody to run it for "any purpose". Of course it does not fit the requirement for free software. I doubt that "can you run it?" is meant to be interpreted as: "can you run it, s

I do not think that there is a coordinated effort whatsoever to disrupt Free Software communities (at least not at industrial scale, maybe there are groups of 3 or 4 people with a similar mindset doing things together, but that is the case

You can't balance despicable policies by being merely competent in your other missions.

Also such licenses are not Free Software. And from a practical point of view (existing in the ecosystem) that matters a lot.

You would be a fool to buy things from Chef after they show such a trivial vulnerability.

by temac 7y ago
Besides the political statement, do you have any technical opinion about an organization such as Chef shipping things that have runtime deps to third parties?

Not it is not fine at all. If you have too many instructions but not enough, your whole CPU will run slower mostly on non AVX-512 instructions, and maybe even your whole package => the end result will just be slower. Not to say that thos

by temac 7y ago
Nope. At this point given the state of the market, and given what AVX512 does to begin with (so maybe the "at this point" will be for forever), it makes very very little sense to use it everywhere. It would just be actively detrim

That's not a very good example; this code is generic (although non portable) C optimized implementation, not something making use of fancy processor instructions. It is even less probable that the compiler understand it and manage to o

Although you probably overestimate a bit the impact of uarch diff between haswell and zen, there is some truth in theory in what you said. In practice, zen is quite close to Skylake in terms of general uarch principles and main figures, and

Can you also benchmark against std::deque?

I think there are some static analysis tool. At first it was some proprietary tools ran by who knows who, but this was obviously an enormous problem in the context of Linux dev, so IIRC somebody wrote something (that might be quite primitiv

Linux only compiles with at least semi-recent compilers. The minimum version for GCC even has been bumped not too long ago. They certainly are able to handle C99 style declarations. Why Linus hate them, I don't know, probably he could

It was my understanding that such redundancy for automation purposes did not even exist, and that despite having 2 AoA sensors only one was selected before a flight, with the computer switching the one to be used between each flight. Also S

Yes I see that, I was not describing what the compiler should observe to work properly, I was describing the erroneous reasoning it was making prior to the fix. I should have written: non-nullness of 'node' . And TBH I'm sta
709.
by temac 7y ago
Of course there is no UB in the source code. That makes the problem worse, not less bad... Non-nullness is inferred from 'node->child = NULL;' which would be UB would node be NULL. At this point the compiler thinks it is superf
710.
by temac 7y ago
I'm curious why you think that? The origin is absolutely the usual exploitation of UB in the sense that the compiler supposes that code paths that are past one can be elided (because programmers never write bugs, that kind of interesti

The reversed SM64 binary was compiled without optim IIRC though. Of couse you can reverse an optimized binary, just launch IDA and start to have fun to get an idea of the work. Doable, but of course harder.

Your layering does not really have practical consequences that would matter to exclude a field for engineering. Plus you are focusing on the technologies, and while this is important this is really not what distinguish an engineer from a no

Impressive but is this a good idea? Either you need a crazy thermal solution, or it must be way less thermally dense than smaller chips can be. And is it really that much of an advantage to stay on chip compared to going through a PCB, if d

You are talking about mostly source code organization. Which every sane project does. So of course it is unlikely there is something that e.g. draws pixels in the scheduler. But for example there is still some space reserved in the TEB fo
