Hmm. So my question was "How do you conclude that paying by use is not going to be a good deal?" and you quoted by fixed cost observation back at me without making any additional argument. To interpret this charitably, I guess you

How do you conclude that paying by use is not going to be a good deal? In my mind it's quite the opposite, it now makes financial sense to rid your life of daily dependence on your own car while enabling economical occasional car use.

Interesting that there is a 1000x speed difference (0.1 vs 100 ms, in Chrome) between the shader and the JS/WebASM versions even with just Intel integrated graphics.

There have been many previous attempts at "throughput computing", meaning many slow cores or threads for server workloads. 3 generations of Niagara (UltraSPARC T1 and descendants), SeaMicro's box full of Atoms, etc. It doesn

FP continues to be on the upswing, also in the JVM world and frontend (compile-to-JS) languages.

I have to confess to not actually being a Rust user. But, isn't for example std::io used by most Rust programs?

Rust has a big standard library that is linked by default. Using it with no runtime is pretty rough going and is usually done only by people targeting bare metal microcontrollers or OS kernels, because it loses a lot of the power normally

Nobody can agree on what "politically neutral" means, it's not a useful criterion. Every subreddit listed at https://en.wikipedia.org/wiki/Controversial_Reddit_communiti... could be argued to be politica

Refcounting and costly abstractions are in wide use currently - just done in C without the safety.

Strong vs weak typing also means whether you can circumvent the type system. So C/C++ are weakly typed systems because the laws of types are more like guidelines there and you can cast around them to reinterpret memory contents.

Not really portable. Even x86 has lots of variation between supported operations and vector length. ARM similarly has variations between ARM versions. At least for the abandoned JS SIMD effort, they stuck to the least-common-denominator SIM

I'm still not sure why you insist they are not comparable. GPU compute vs CPU SIMD is a very standard comparison and image recognition applications, like the one discussed, frequently support both.
134.
by zurn 9y ago
Both can be be used to accelerate the image processing application in question. GLSL is compiled on the fly to GPU instructions that exploit parallelism opportunities, but more so than SIMD because GPUs have greater internal paralllelism.

SIMD is like the kids version of GLSL, which works today :)

This is the path to formal methods. You will build formally correct programs very slowly, usually too slowly for the world/app domain.

Note the GP's use of "delivering" - people have been using non-JS languages for a while and they have mature tooling & good communities. Elm, ClojureScript, etc. And the semi-Javascripts like TypeScripts and CoffeeScript.

A big category of cluster-friendly HPC cluster codes works by running in lockstep on all the nodes. Apparently it works quite well for things like weather forecasting where the problem is naturally divided into a grid but there is still sig

Is this clear cut in the terminology? A plausible definition would also be that it's still symmetric MP if remote memory access has non-uniform performance - since the nodes and their memories are symmetrical. After all, you get that j

There have been attempts. Safe-C and Cyclone come to mind.

I'm curious why the LRO improvement gave such a large overall boost, as the workload should be more about sending than receiving. Are the incoming TCP ACKs or TLS control traffic so frequent that you can get 15% more total throughput w

Sounds like the whole discussion is kind of blurred by the definition of what a start-up is. IMO the article misrepresents the cited study[1], which doesn't talk about "start-ups". It could just as well be represented as: in

Lots more game companies too, from AAA companies like DICE and Paradox to indie games.

Google promises 3 years only if you buy the device on release day. Our Nexus device at the office got ~18 months. But yep, the mid/low end devices are often basically abandoned soon after release, or get 1-2 midlife updates so that Dec

Same methods that are there for enforcing other laws of course. We had a functional copyright system long before DRM.

IO interrupts and scheduling based surprises were a pretty small part of the list, though.

I wonder how they arrive at the X microsecond worst-case number for the software-based solutions. Does it take into account a perfect storm of APIC interprocessor events, interrupts, SMP cache coherency protocol worst-case behaviour and cro

If you want to trade off simplicity for lower costs or lower latency, you can also use WebRTC data channels that do p2p communication between the players.

For a critical article, the headline page oddly parrots the DRM proponents agenda: "At issue was how to support copyright-protected video in web browsers". Copyright protection is of course independent of DRM, and it would be argu

What's the "actual cost" they compare to? It needs to include environmental externalities like CO2 contribution to global warming.
