For scale we're talking > 2TBps linear read and probably > 500MBps random 4k read in both cases, compared to on the order of 50-500MBps limit on the CPU side depending on threading etc. So still CPU limited. If there's any p

As in 20% faster on the M2? At least for gzip defaults the per core throughput on my M1 is around 50MBps.

by hedgehog 4y ago
It seems pretty unlikely that many people have a workload that is highly sensitive to read throughput, has a disk footprint so small it fits on a 512GB SSD, and where the cost of slower disk outweighs a 20% faster CPU.

Until grocery stores accept GitHub stars and good vibes most people will need to be paid to build software.

Fumes from many cooking processes are also pretty bad for respiratory health.

There are a handful of studies showing an association between longer commutes and negative health outcomes, I think down mostly to the lack of exercise in sitting in a car for extended amounts of time. Hard to say if people working from hom

According to the w2c2 readme "Coremark 1.0: ~7% slower than native" so within the generated code performance sounds quite good. What I'm curious about is how hard it is to build a library target via this method and how much o

Your memory is incorrect. The branding sequence was System (from before I remember up to 7.5) -> Mac OS (7.6 to 9) -> Mac OS X (10.0 to ??) -> OS X (??) -> macOS (starting after 2015). Edit: Sibling comment from htimsenyawed loo

Take this detailed answer and view it with the perspective of having to fit BASIC along with everything else in ROM into 12KB (in the case of the Apple II).

The docs explain what this is more clearly than the readme: https://misskey-hub.net/en/docs/misskey.html Apparently the name is somehow derived from this song: https://www.youtube.com/watch?v=Efrlq

I don't have any experience with DirectML but it sounds promising.

I wouldn't hold my breath, and anyway at this point NVIDIA has faster chips and more supported software all the way down the stack. My previous startup tried to solve some of these problems and we built what is as far as I know still t

I used to believe this idea that the tools in academia would carry over to industry. Now I think it's only weakly true, that is there's not really a big barrier to switching to other options like TPU or maybe Trainium (haven'

Last I checked they see deep learning training as a niche market, their strategy is to try to win big contracts (HPC etc) and then supply software specifically for that. Then "the community" will supply software. Having spent a bu

Big question is why? Would competing for entry level researchers buy them much?

My bet is this is coordinated with a lobbying effort to prevent more right to repair legislation.

It was typical Apple arrogance but the actual issue is not nefarious, aging batteries deliver less and less current and eventually it makes devices crash or power off unexpectedly. Always been that way. They just figured out you could impro

I use Qi most of the time at my desks, cheap chargers from Anker and Ikea. Alignment by touch is second nature and easy with one hand (vs two to plug in a cable). It probably depends what your usage pattern is but I find it very convenient.

Sure, plenty of historical examples of things that were in wide use and then misunderstood or forgotten. The scale and precision of cities like Angkor Wat or Tikal including canal systems. Large scale systematic fish trapping and fisheries

For whatever reason there's a consistent tendency for people of every era I've read about to think they are the smartest and most advanced that have walked the earth, topping a long arc of progress. The more I read about history t

I have quite a few complaints but that particular thing works fine for me.

Yes, in the Cray design a vector instruction processes one item per clock so total latency increases with number of elements. Only parallel in the sense of pipelining being a form of parallelism. Something like an AVX-equipped Intel CPU pro

Lower overall return of light which causes low SNR, how that manifests is a software question. I've worked on similar systems and read some of the papers about the pulse ox problems, the problem is pretty well known for the finger clip

I think this is backwards, the early Crays and maybe other machines used essentially serial + aggressively pipelined CPUs while modern CPUs do actually execute operations in parallel via multiple ALUs but are from a programmer point of view

Good overview. "Vectorized" is an old term that's been around since the early days of supercomputers and maybe before, not sure where it came from. Numba does a bunch of different things for code written to the Numpy API incl

by hedgehog 4y ago
If you have numeric code that's too slow in Numba your next stop will likely involve a big multi-language effort and GPU specialists and none of that would be in Go except maybe a wrapper for your apps.

It should be a 3D scene with a button and light on a table connected by what looks like a WireWorld sim. Pretty neat. Works on Mac Firefox but not Safari. I don't know enough about front end development to guess at what the console err

It's a common misconception that regenerative braking is the only way hybrid cars charge their batteries. The other common situation is when the driver requests less output from the engine than it can produce efficiently. The engine ha

I don't think that's what the Raytheon prototype is doing. It sounds like they're capturing some of the mechanical energy from the engine during descent and putting that into the battery for later use. Hybrid cars do that, wh

I'm not sure about this specific case but generally commercial wide coverage satellite imagery is not high quality enough to reliably see these kinds of formations. I'd guess they contract some combination of imaging including LID
