Aside from the cost, ACQ107 is not very reliable in my experience. I have one that randomly drops the connection every now and then, even at sub-10Gbps speeds. Switching to a different NIC makes everything rock stable.

In my experience every single (AIO) water cooler I've tried has been significantly worse in terms of noise than a decent air cooler.

Specifically the pumps. Those things have an obnoxious high-pitched whine that I personally find unbearable, especially during low/idle workloads.

It's possible that the actal dB level is lower, but the frequency and sound characteristics matters. A lot.

> libc is big and complicated and most programs only use a tiny fraction of it. Is libc a problem for the ecosystem?

IMO yes. I definitely believe having basic common functionality (malloc, printf, memcpy etc.) provided by one library with all the crazy/obscure stuff that very few people need or want somewhere else would be an improvement.

Because that would break compatibility. The way shadow stacks are implemented means they can be enabled in existing software without code changes.

If one were to design a modern ISA from scratch it would make sense though.

> event 1 is always “Site wiring” and every other event is always “None”, even though there have been multiple power events, and there is no site wiring issue

Some UPS:es are adamant about wanting live and neutral on specific pins on the power plug and will throw that error message if they're swapped.

If it's a reversible power plug, flip it around. If the power plug can only be connected in one orientation the outlet is likely incorrectly installed (which is not all that uncommon, as 99.99% of stuff will work perfectly fine with live and neutral swapped).

th3typh00n — Sat, 09 Sep 2023 19:11:54 +0000

Yes, for 32- and 64-bit registers. Most modern x86 CPUs has fast paths for 'xor reg, reg' which performs the zeroing using the register renaming mechanism instead of actually executing anything on the back-end. So the only cost is that of decoding the instruction.

Recent Atom CPUs (since Gracemont) do support AVX and AVX2.

The point is that avoiding Apple and Google, while it may be technically and theoretically possible, is going to make your life extraordinarily complicated and is completely unrealistic for the average person in our modern society.

When the cost of the electronics is a tiny fraction of the overall product the equation is different. Automotive is a perfect example where spending extra on a few key components is a worthwhile investment if that can increase the reliability of the entire vehicle.

Why would you have spaces in source code filenames? It's just a bad idea in general and makes things more complicated for no reason, regardless of what build system you're using.

In some European countries you can in fact do exactly that. Useful if you need to ask someone to move their vehicle for example.

I'm sure there's some kind of hypothetical downside, but not one that me or anyone I know have encountered at least.

Always storing contacts using the full international phone number is definitely the way to go. As someone who, at least before the pandemic, used to travel a fair amount this basically eliminates all issues and makes everything "just work" everywhere.

To be honest I'm surprised that phones doesn't do this automatically when you type in a local number.

ifuncs is a non-standard compiler extension that only works on certain operating systems.

Developers that cares about portability are obviously going to stay far away from such things.

Telemetry-specific Javascript on the other hand is prevented from executing by many ad blockers, for good reasons.

Because the number of transistors used for that functionality is absolutely negligible, so removing it has virtually no benefit.

I haven't seen any numbers on that but there's literally zero reason to run a Xeon Phi without using AVX-512, so I'd assume no design considerations were taken to optimize the clock frequency for a non-AVX-512 use case.
