Out of curiosity, color CRTs do have a kind of native resolution. It's the RGB pattern used to show colors. See: https://www.reddit.com/r/askscience/comments/3a2tx6/do_old_c...

Rust is surely fine, and an improvement over C, but its main advantage is that all the rust code is written now, when everyone takes more care about security. It doesn't have to deal with 40 years of bad legacy code written by sloppy d

And Ford could have asked: "Do you prefer it faster or that it's a horse?" - "I already have a horse." - "OK, I'll make something that goes faster."

If you use __builtin_expect() the Intel compiler uses a branch. I mean this way: if (__builtin_expect(index >= cap,0)) { ...

Is this equivalent ? At least to me this seems a more common pattern than using memcpy(), and I expect to work better on old compilers. static uint32 read(const void *ptr) { const uint8 *b = (const uint8 *)ptr; return (b[3] <

Is really rust not needing valgrind, and more specifically the memcheck tool ? OK for leak detection. But is it really able to detect all not initialized memory accesses ? Anyway, I suppose that rust can still benefit from other valgrind to

Can the seeders enforce the rarest-first approach giving priority at lechers that ask for the rarest chunks ?

Having a feature implementation splitted in a sequence of commits helps a lot the review process. This often involves the use of interactive rebase to cleanup the history before presenting the branch for the review.

I don't get the issue with msvcrt.dll. It's available in all Windows installations, so for my concern, MinGW produces freestanding applications, because nothing additional needs to be installed.

I consider the CPython switch from Mercurial to git the final declaration of victory. I still have to understand how CPython could miss the symbolic meaning of this decision.

Google for Linux OOM Killer (Out Of Memory Killer). It's really annoying, your application may get killed without any way to react, even to just print a "Low memory" error.

And don't forget about helgrind and drd for multithread code. I would not even dare to use threads without the support of these tools. In fact, this seems a side where C has a big advantage over other languages.

Being smaller usually results also in being faster for the cache effect.

I follow a similar approach. Valgrind is a must. Just using malloc()+memset(,0,) in release, to override someway the Linux OOM killer. In starvation, malloc+memset "usually" results in a malloc() failure, instead of the process be

I see a value in this approach. I don't known your experience, but as soon you have a well known OpenSource project with binary distribution, you are going to see it available in a lot of scam download sites. In fact, the OpenSource li

I implemented what you describe using the BSR (BitScanReverse) instruction as base of an indirect addressing of an exponentially growing data size. Essentially, instead of a direct addressing like V[i], you can do VV[log2(i)][i]. Where log2

Using strlcpy is like suppressing the "Division By Zero" exception and have divisions to return a fake value just to let the program run. In some case this could be even useful, but it's for legacy and sloppy programs that no
