If the cost of adjusting to the new thing is greater than the "objective" benefit it provides, then it is better not to change.

I find the most readable, unambiguous thing is to define explicit macros or constants, e.g. if(ckd_add(&result_add, a, b) == CKD_SUCCESS) { ... } or alternatively, if(CKD_SUCCESS(ckd_add(&result_add, a, b))) { ... }

This is already present as a builtin in in GNU C (as indicated in TFA) and it already results in the optimal code: https://godbolt.org/z/qc4zvav7E

I think it's pretty clearly feasible in the specific example GP gave, since -fwrapv does this for GCC and clang. In principle it should be do-able from code level with e.g. 'pragma gcc optimize("frapv")' (but the gc

If "i" started out higher than "n", the loop would exit immediately and there would be no increment. More generally, if "n" is an int, then even if n is modified each iteration, the "i < n; i++" st

If it would result in different behavior in the event of an overflow (which I think is generally not the case), then no. A typical for loop (using <) can easily been seen to not overflow, so this is a rare case anyway. Loops using signed

Looked into this and it appears it was not the case; the docs were confusingly written, and the docs appear to have been rewritten some time ago https://marc.info/?l=gcc&m=102068997020453&w=2

Wouldn't they be at a strict disadvantage because they cannot eat other typical-chirality-producers for resources?

Oh sure, the point is more that Ethernet/IP has to coordinate two separate ID spaces at all, whereas AFAIK no other packet-based protocol like the ones mentioned does this, so in that sense those protocols are better.
462.
by dooglius 4y ago
Why do you say that these protocols are worse than Ethernet/IPv4? I'm not intimately familiar with any at L2/L3, but I don't think any have hacks as bad as ARP. (USB does have some weirdness at L1 though I know.)

I suspect there are just too many real things it would actually break. Alarm clock websites, for instance, off the top of my head.

Did the "cloud hype" really "blow over"? Seems to be a pretty big thing nowadays.

Better to just add a new stop button rather than overload minimization. In any case, if your concern is web pages, your browser needs to implement this, not your window manager (unless you are not using tabbed browsing, which I doubt).

This seems like an uncharitable take, the set of axioms and definitions used doesn't really fall under "mathematical truths", it's about agreement on what is implied by a given set of axioms. Even on Earth many people wo

Division, remainder, and memory access are data-dependent, someone who didn't know better could easily put those in a cryptographic algorithm (or worse, a compiler could transform a program into using these).

Wonder if this is because of the zero-value optimizations on Ice Lake: https://travisdowns.github.io/blog/2020/05/18/icelake-zero-o... https://news.ycombinator.com/item?id=23225260

I'm sure it's still true that you can ask! Whether it works I expect will depend on the professor.

From TFA: > After looking at some logs we do end up with potentially bogus panel power sequencing delays, which may harm the LCD panel. So sounds like it can cause some out of spec stuff at the analog level, which could plausibly result

Not really, I've nearly fallen for this, it looks like legit medicine if you aren't looking carefully to see the part where it says "homeopathic".

You just have to take out square factors from each, and combine terms with matching sqrt(n), and that will be unique

So what is N here? The sequence length, number of digits across all sequence elements, sum of all elements?
