Regular reminder that profit is a trailing indicator of success. If something is growing fast and bringing in revenue, you should be spending money to grow it as fast as possible. So profit *should* be negative while it's growing. When

It's more and more true, though, that the physical condition of your CPU and heatsink affects performance. Because under heavy workloads they're often thermally limited, and every 0.01 K/W of thermal resistance makes a notice

Has the hypothesis that this is noise from a class-D amplifier (which I assume most commercial speakers use) been eliminated? Those generally switch at MHz frequencies, but have subharmonics all over the place except the ones that have been

Once the major browser engines support it, it's de-facto legal. This also explains why there are so few alternative browsers. Writing a new browser that supports everything that happens to work in the major browsers is ridiculously har

It's not any kind of paradox. Structural unemployment happens when the skills of the work force don't match the needs of employers, so there is both unemployment and difficulty hiring. Structural unemployment is usually high when

Windows debug builds add extra sanity checks for which it needs extra members in types. For instance, a vector<T>::iterator is just a T* in a regular build, but in a debug build it also keeps a pointer to the vector so it can check bo

I think each dependency is only counted once, even if it’s recursively included many times.

What’s the use case overlap between symbolic and huge? I might expect that with most huge expressions (they talk about disk space being the limit, not memory) you’d be satisfied with a numerical approximation. Does someone need to simplify

From the paper, the light is UV-C at around 140nm or 8.4 eV. But it has to be very precisely the right energy to cause the transition, since nuclear states don’t have any place to dump excess energy to.

And, to be fair to both sides, politicians who have received money from taxpayers should not be allowed to speak.

Can you clarify what you mean by "no information processing advantage?" Does increased speed or memory capacity provide such an advantage? Or would you also claim that 2024 silicon has no advantage over 1994 silicon despite severa

A little, but the design of the support structure is dominated by wind loads. Depending on where you are, it can need to survive wind gusts of 90 - 160 mph. At the low end, 90 mph corresponds to 1000 N / m^2, which is more than the wei

It's not doable at the board level. High-end GPUs use HBM in the same package, connected using a silicon interposer.

There is some scientific publishing outside the standard format, sometimes corresponding to a conventional paper. To pick one I liked recently, https://www.cs.utexas.edu/~lqiang/rectflow/html/intro.html is ni

You are correct. I think I was misremembering problems caused by SIMD types that require 32- or 64-byte alignment.

by tlb 3y ago
Yes: OSX on ARM64 has alignof(max_align_t)==8 and alignof(__int128)==16. And malloc only provides 8-byte alignment, so if you're using types that require 16-byte alignment, you have to call aligned_alloc. Also, the stack is only 8-byte

x86 processors have a LOCK instruction prefix, which makes some instructions atomic including increment. Increment is nontrivial to make atomic, because there are two memory accesses: read X and write back X+1. It's a bit slow, becaus

Interesting project. I almost wish I had a concurrency bug to test it on. > Guest software running in the Antithesis platform still experiences concurrency similar to a multi-core / multi-machine system, thanks to the process schedu

It’s usually a requirement that, in an emergency, you can disconnect the electric opener and open it by hand. Certainly if there’s no second door to the garage, this seems essential or you’d be trapped if power or anything in the opener fai

Appeal to nature is bad as a source of ultimate truth, "nature does it this way therefore it must be better." But it's good as a source of hypotheses, "nature does it this way, perhaps we should try it?" This paper

Part of what it means to be "good at regulation" is to anticipate the likely consequences of regulations. So a regulation that says that "businesses must now give away their products for free, unless they honk each customer&#

Apple has a long history with ARM, going back to the Newton. Back then (or even in the early iPhone era) they didn't have the time or resources to develop their own implementation. They could afford to develop their own ISA now, but wh

That feels a little unfair. Every driver in the 1920s would be be breaking today's laws. They were exploring a new technology when it wasn't clear yet what the rules should be. The laws at the time (inherited from horse-drawn vehi
