If I remember my long ago physics classes correctly, irreversible computation inherently costs energy: you can't get its energy "consumption" down to zero because of entropy, no matter how efficient the technology. Our comput

The "when done correctly" is a huge caveat, given that what you're replying to does it incorrectly. If X and Y collide, so that SHA-1(X) = SHA-1(Y), then f(SHA-1(X)) = f(SHA-1(Y)) no matter what f is -- so you get a collision

I appreciate the candor but at the same time wonder about the lack of counterfactual experience. What if your parents had stayed together and you grew up in a household of constant fighting? Would that have been better?

From the planning document: > Branching: Done > Single instruction multiple thread (SIMT): Planned I guess we should be supportive, and it is impressive how far they got on the software side, but boy, is the author in for a surprise.

My cynical take is that some of the smarter players in the field were worried about running out of greater fools, so they did a concerted marketing push of something new.

Having worked in EDA myself, though not on these final signoff steps, I agree that purely geometry-based checks really don't need doubles. Most of it should just be done as 32-bit fixed point. Both because it's better for performa

What you've described is actually for placement, not routing, and is in fact a good analogy for the first step in many placement algorithms. Interestingly, placement is much harder than routing from a complexity theory point of view

If you squint hard enough, Git is kind of a permissioned blockchain. So, I wouldn't dismiss the possibility completely. But yeah, it's difficult to see it becoming mainstream . Git certainly isn't mainstream.

I mean it's bound to be true and actually more extreme than that if you're taking the entire population as your reference. If you take as reference the subset of people who are trying to get to scientific breakthroughs, then yea

A modern renderer does rasterization followed by a sequence of post-processing steps that you can think of as compute dispatches (kernels) running one thread per pixel. The reality is often somewhat more complex, but that's a good firs

What does he mean by a 32MB TLB? Certainly there isn't an actual 32MB of on-chip memory dedicated to a TLB. So does it refer to the coverable amount of virtual memory? But that can't be true either, given huge pages. All in all,

I think their point was that there is no selective pressure on the males to reduce their level of mating violence. From the males' perspective, the situation looks like a prisoners dilemma.

The problem isn't one of technology but one of procurement processes. Electronic voting is largely a solution in search of a problem (purely manual processes work fine for tallying votes), and so the field is dominated by bad actors se

The interesting question is: what happens in modern out of order cores? There can be hundreds of instructions in flight, including long dependency chains of loads. It's probably not too difficult (using cache misses) to construct a sce

Those words are not some sort of magic spell. Licenses can't override law unless the law explicitly allows them to, and the law generally distinguishes or tries to distinguish between honest mistakes and malicious behaviour. IANAL and

I can second the recommendation of tig in the sibling comment. Additionally, git itself comes with a simple `git gui` command that allows you to do partial commits on a line by line basis. It also has a nice "amend last commit" mo

This is the mechanism that I had in mind. It's actually a really good one if you have lots of concurrent reads and few writes because there isn't going to be any cacheline ping pong. With a more traditional read-write lock, even t

by atq2119 5y ago
You can use RCU to do this, but I'd argue that everything else ends up being more or less a lock by another name (maybe you could do read/write where the read is optimistic, but at least the write side will have some sort of lock)

Your spin loop could easily miss the time during which *b == 0. The article explains that. A separate phase bit is required.

It's a nice write up. I did this once with a slight modification. The phase really only needs one bit, and an arbitrary number of threads can be supported in a number of ways by having the last thread to arrive at the barrier clean up

I totally agree that stack PRs are a good idea. It's how Git was meant to be used (see the Linux kernel's development process). The problem is, they're a pain to work with in GitHub and so only a very small number of people e
