But there is a significant amount of scientific evidence that demonstrates that airplanes do in fact work.

I think 'dragontamer read the question as "why does the photon move away from it at the speed of light?" (as I did). There isn't really an answer to that question, since it's just the way the universe works. Saying

This is great. I've seen MoltenVK before, but did have any reason to justify getting it. I am a really big fan of Vulkan. While it takes a bit more work to get going and does less for you, I find the increased transparency very valuabl

Definitely. The STM32Fx line is awesome. I was mostly thinking about alternatives for people who are currently using Arduino and want to keep the same toolchain, libraries, etc. but at a lower cost. If someone is comfortable moving outside

I don't know about AMD, but NVIDIA GPUs also have internal protection. Tesla and Quadro GPUs have had internal error detection on registers and cache since Fermi at least. But this is totally irrelevant anyway, the comparison we starte

It's probably closest to a finite state transducer. No guarantees that what I described above is exactly the definition, though.

No. They mean a set of states, a set of input symbols, a set of output symbols, an initial state, a transition function, and an output function. The output function maps from the state to the set of output symbols (or sometimes from the sta

Not usually. "State machine" is typically used to refer to the more general concept of a finite state machine, which includes Mealy and Moore automatons. DFAs typically are not viewed as having an output (or arguably a single bit

Could you please clarify your last paragraph? You can definitely "do software on a GPU," and GPUs have as much error correction as anything else.

I don't know much about the 17th century, but late-19th century "peer review" was definitely way more fun than today. There were a ton of published criticism by peers, often with colorful language and creative ad hominem atta

People tend to disregard statements like this, but they are absolutely 100% true. I'm still using my iPhone 5S on iOS 8, and I am very happy with its performance. I've never had any issues with sluggishness, lag, etc.

Loads of people do FPGA development for hobby projects, which isn't "software." FPGAs can dramatically improve problems with latency, jitter, power over software implementations, yet are still quite accessible.

Agree re: official Arduinos. If you still want to use Arduino, I'd highly recommend going for Arduino clones from China. You should be aware that the USB chip is different so you may have driver issues, but I haven't had any issue

Thank you for answering. I still don't see why either of those justify warning the user about the whole page. For the donation button, the browser could easily warn you with a big "insecure!" page when you click on the button

I edited my post before your response to change it to "flagged," but failed to call out the change initially. Sorry, it's fixed now. For a lot of people, a big scary warning page that says that a page is insecure is essential

No. What he said is that Google says that https prevents MITM, but never mentions that they will still be able to do it. I don't see a dismissal, just a criticism of Google.

None of these statements convince me that http sites should be default flagged as insecure. Take this site, for instance: http://wilsonminesco.com/6502primer/65tutor_intro.html . It is a great resource, but is not avail

GPUs can only access pinned memory that is intentionally mapped into their address space. Also, each context gets its own virtual address space on the GPU, isolated from other contexts. There can still be issues, but it isn't quite as

Thanks for clarifying, that makes sense. I'm glad you saw the edit. I initially wrote it based on my first interpretation of what you wrote, but after re-reading I realized that your description was totally accurate, I just misundersto

This is an excellent question. The current wine implementation using OpenGL should mirror the behaviour of D3D, since it is using glMapBufferRange and passing GL_MAP_UNSYNCHRONIZED_BIT when possible. I am also wondering what is actually goi

by twtw 9y ago
Wine uses glMapBufferRange when available, and has logic to translate D3DLOCK_NOOVERWRITE to GL_MAP_UNSYNCHRONIZED_BIT. I don't understand what the current implementation is doing that is causing wined3d_resource_map to block. https:&

How long has Google had the TPUv2 for internal use? I was under the impression that V100 and TPUv2 where developed around same time. They were certainly announced around the same time at least. Just seems weird to say "it used to,&quot

Sure, for a customer. But from a technological point of view, performance per dollar doesn't tell us everything. A company could subsidize their compute service and get astounding perf/dollar with a not particularly impressive chi

IIRC, TPUv2 uses 16 bit floating point in some format with higher dynamic range and lower precision than standard fp16. Can someone confirm? If that is right, is the "Tensorflow-optimized" Resnet-50 using 16bit floats when running

Is Electron still single threaded like Node?

No, this is good. Don't get caught up in the Vim-Emacs wars or any of the language wars - they are mostly a waste of time. Recognize that languages have "areas of expertise," but these often overlap. I get mad about Electron
