Virginia (Dominion) electric rates went up dramatically, and are now in the same rough price band as 29 other states, because they were well below average. Important context, in my humble opinion.

The question is whether there exists a nexus between the supposedly obstructing behavior and the judicial proceeding. It doesn't even matter about the intent, if there was no nexus. Can the act of having moved these materials actually

by jeffbee 3mo ago
Yeah, but I think the question is whether his actions did in fact obstruct justice. Both are relevant.

You're ignoring the other main economic foundation of VPNs: the service is in fact run by the cops, at a loss.

AMD's NPS4 mode isn't exactly user-friendly, I agree. But you can put it into NPS1 mode and relax. Graviton 5, as a counterpoint, doesn't give you the option. Physically there is a 2D mesh between the cores and the memory con

My question: why do mainstream users tolerate NUMA? 99% of you don't need to. Single-socket servers exist and they are not only tolerable but better in most ways. Dealing with NUMA in software consists of trying to logically partition

It's unfortunately a hard message to sell, but your program itself should never be backed by a file, for this exact reason. All code should be remapped into anonymous memory that is 1) right where you want it; 2) backed by hugepages; a

This operation should not have been retried even once. The overall operation failed due to an unsatisfied precondition that a second attempt could not have rectified (the non-existent target resource). The status of the job should have tran

There's lots of stuff in an electronic assembly that's microphonic, not just speakers. I don't think it's possible to look at an assembly and conclude that it doesn't contain any microphones.

I thought TPUs couldn't reasonably run LINPACK at all because TPUs do not acknowledge that FP64 exists. I know Google wants to compare their stuff to El Capitan or whatever but the comparison does not seem valid to me.

I mean, that's how people get hacked. If vlc crashed on my computer, and every day I should raise thanks to my gods that I do not use vlc, I would immediately unplug it and thoughtfully consider the circumstances under which it would b

le sigh, c-ares. Very predictable outcome. If you ever find yourself entertaining the idea that you will simply write non-blocking network protocol stacks in C with manual lifetime management, slap yourself. It doesn't matter if you th

Yeah. I typed the comments on my phone without bothering with the docs. I probably got all the other classes wrong, too.

It seems that you could have reached this conclusion faster by elaborating on your use of the profiler. Don't assume that cycles are spent on instructions. Look at your IPC and drill down into what CPU-bound means for your workload. In

Algorithmically hopscotch has a better strict worst case whereas swiss tables have a degenerate O(N) lookup. But there are a lot of maps like that. robin_hood::flat_hash_map is very fast but I can create insert sequences under which it will

A more recent benchmark is https://martin.ankerl.com/2022/08/27/hashmap-bench-01/ However, it lacks the newer Boost stuff which is very fast. The Hopscotch map was interesting at the time but due to unfo

I think most people do not have 10g UTP infrastructure they want to exploit, but many people do have 2 computers they'd like to connect together at high speed, and these people are far better served by just connecting those computers&#

Also, a big cabinet into which you plug varying amounts of hardware capacity, then use the control plane to partition into various virtual resources, describes at least at the conceptual level IBM going back decades.

With only 288 128GiB DDR5 ECC DIMMs? I'm sure that doesn't cost much.

This seems like a totally crazy statement. The only common thing that a current and 50-year-old 911 share is that there are six holes in the engine block.

It wasn't even long! It seemed much shorter than the typical LLM-expanded drivel that crosses the HN front page daily.

That certainly is a bag of words. I'll congratulate anyone who can convincingly explain why the TCMalloc design diagram is in this blog post.

People who say this is a "gray zone" are practicing motivated reasoning. It is not gray, they are just illegal. There doesn't have to be a "path to legality" for illegal motorcycles. The only "path" necess

Yeah I've never heard of it either. I was just trying to steelman their motivations for this demo.

These things are already banned by UCI. Any kind of display has to be attached to the bike. I can see a HUD (not this one) for non-pro club riders, though. It might be nice to be able to see your stats while holding a wheel at 20+ MPH, with

There are HUD glasses for triathletes, and have been for years. That's why the ANT+ "extended display" profile exists. These HUD glasses have been on the market for at least 15 years. UCI rules prohibit them, which is why the

I don't really agree. The energy component of opex still dominates over the depreciation.

Shipping uses so little energy that switching it to synthetic liquid fuels while we figure out something else is plausible. More plausible than reverting the fleet to 2000x more sailing vessels.
