FWIW that phenomenon is a geometry thing, not just a fluke. If you are on a collision course with an obstacle at constant speed, than the angle remains constant (as the configuration preserves congruent triangles until impact) and the obst

The random MAC is generated only once per network, and re-used for every subsequent future connection to it, until the network settings are reset

True, I don’t remember the details for writes, and the complexity of managing high/low water marks makes it even trickier for optimal code. And large kernel send buffers here mostly avoid the performance problem here anyways. But on a

Edge-triggered requires an extra read/write on every epoll relative to level-triggered though because you must exactly trigger reading the error state (EAGAIN), so it actually can be much slower (libuv considered switching at one point

I think you are making more of a distinction between optimizations and runtime, not compilation. Doing compilation is about taking a lot of arbitrary user-input (in the form of urls and cmake files and code edits) and executing that. Then o

That rate looks not-statistically significant in that study. And also not too “serious” (in layman’s terms, not medically speaking) as the baseline rate for the placebo was 18/10000 (the 1/1000 is a delta value above that)

It seems the article was going to say it was an increasing drug-use (opioid) and mental health epidemic in the US (which seems likely true). Then took a left turn and blamed the deaths of middle aged people on getting a Covid vaccine as a b

I assume the query from Apple to the phone is not "are these (potentially spoofed) coordinates X trusted", but rather "is your current location trusted". The later doesn't seem like it would leak any useful informat

Just to throw a concrete number on this, extrapolating from Wikipedia, about $350k family income will put you above the 1% mark. I assume IPO-windfall would be considerably higher than that and maybe be at least top 0.1% that year ($2M+), w

It is only rare in a particular year. If a given person is assumed to only earn that for 1-2 years of a 30+ year career, then 10-20% of all people will be a top 1% earner, by rough math. Still rare, but not nearly as uncommon when looked at

It could also be there is only enough profit for one, so the game theory equilibrium is zero. So Spotify could be the only player large enough for Sony to profitably encourage. Although that theory doesn’t account for them not giving the op

Does rust also add an pthread_atfork handler? Otherwise, it seems likely still unsafe for rust to claim to support calling fork (for execv) or posix_spawn, as most libc call realloc on the `environ` contents, but do not appear to take any c

Do they usually have guest account access disabled, and would that help if enabled? I once saw a theory that guest account access can help because it grants the third party the ability to connect it to any WiFi network, allowing it to “phon

In my experience, being similar to RTLD_LOCAL avoids a whole slew of sharing/unique accidents compared to the pile of hacks that is ELF. It is sometimes both the hardest and easiest platform to work with since it is the conceptually mo

Yeah, now that quelsolaar clarified, I am fairly certain that claim is not true, for exactly the reasons you describe. Of course, there is also the practical example of the mingw compiler, which does implement C11 for Windows, as a counter-

Sharing the memory of a loaded library is not a problem though. Every major operating system has done that for decades. That is just a consequence of copy-on-write pages though and doesn’t affect process isolation. Unless you meant somethin

What is “observable”? Only atomic seq-cst is order preserving, and even then only if there is no data races, and only if the compiler thinks it could even be observed by another thread. Otherwise, the compiler (and CPU) can and will choose

by manwe150 3y ago
How do you link that? I thought I knew the API pretty well, but that is a new one for me. volatile is only ordered with other volatile calls and is otherwise UB when combined with non-atomics. Whereas an atomic is well-defined for ordering

On Linux, applications are required to load the libatomic shared library to correctly implement the full standard (on some older platforms like ARM, this is true even for small values since the hardware didn’t have an exchange instruction).

by manwe150 3y ago
At the hardware level, there is no distinction between a regular load, a volatile load, and a relaxed atomic load (assuming small sizes and optimal alignments). But the compiler can still can do things that break your code or that miss opt

Acquire loads (and stronger) are required not to loop forever, if they could be observable from another thread. It is mentioned in the linked paper.

Yes, rust is a great language. I love what it does. It also has memory leaks, because it is missing the cleanup part of the GC so it can’t deal with reference counter cycles. Well, there is boehm if you do want to take on that complexity. B

But then mark and sweep also doesn’t have to free the memory (it just does a bulk sweep occasionally), and RC languages do need to free memory used to hold the values later (they have to run expensive compaction and locking steps). So defin

That card would be dead (non responsive or short circuited) by the time it made it to Mars. Rough rule of thumb I have heard is add 2 zeros to the cost of every IC for space grade stuff.
