It takes tens to hundreds of thousands of years. As the gas cloud collapses into a protostar, it undergoes adiabatic heating. The intense heat causes radiation pressure which prevents the protostar from collapsing further. (it will also do

I completely agree with you regarding corporate suicide. The rest of my post is complete speculation. The least nonsense thing I can think of is that they weren't paying their bills. They weren't paying rent, the landlord locked t

They're probably just using an already trained model. They're almost certainly not training a model on-device. AFAIK both the iphone and the pixel have a chip that are specifically designed to do forward propagation on a deep

Replying to my own post: The off by 1 error was incorrect. It's because I was calling the function wrong. I had been giving it the size of the buffer, not the size of the string. Also, someone else figured out that we can just use an a

You're correct, it does not account for alignment. The reason it helps performance is because it allows the compiler to accumulate in byte sized SIMD variables instead of int sized SIMD variables. My system has AVX-512 so 64 byte wide

Oh. Found it. It's because I wasn't using strlen and had been passing over the length of the buffer instead of the length of the string. Only my code had the off by 1.

Speculative execution is all about control flow. It's about what value is in the instruction pointer at some nebulous point in the future. A conditional jump can put one of two values into the instruction pointer, they will either incr

Neat! Although you'll need to make a copy of `n`. The second loop will reduce the value of n to null. Edit: Also, there's an off by one error. should be: #include <stddef.h> #include <stdint.h> int r

So I downloaded your code. On my desktop, with loop-9 gcc I got ~4.5GB/s, and with loop-7 I got ~4.4GB/s. With the following code: #include <stddef.h> int run_switches(const char *s, size_t n) { int res

Err... yes. You shouldn't not keep track of string/buffer sizes.

by nwallin 3y ago
IMHO the original code wasn't written in a way that's particularly friendly to compilers. If you write it like this: int run_switches_branchless(const char* s) { int result = 0; for (; *s; ++s) {

The Carlsbad plant is in Carlsbad, CA. If you look at the neighborhood it's in, the houses are 1,200-2,000 square feet and sell for $2-$5 million. Everything is expensive.

They're great if you have a recent (<10 years old, starting with the Radeon HD 7000 series, released in 2012.) video card which are supported by the AMDGPU drivers. Rock stable and good performance. If you have a 10-15 GPU, which ar

Money. A heavy sub requires heavy support equipment. Heavy support equipment requires a large boat. Large boats are expensive. It's cheaper to spend a little extra on the sub and save a lot on the support ship.

Garbled message. If it were a garbled key, that would explain why the original commo couldn't/didn't decrypt it, but if it were just a garbled key, modern cryptanalysis would have decrypted it already.

Actually, with that particular message, ~~frequency analysis~~ incidence of coincidence will help immensely, to the point of making it easy to solve. With a modern block cipher, a partial key doesn't help. If you have 120 bits of a 128

Impossible to say. The German commo who was tasked with decrypting this message couldn't/didn't decrypt it, and he had the keys. For all we know, some bored German submariner sent garbage over the radio as protest; this messa
