Back in ye olden tymes, video was an analog signal. It was wibbly wobbly waves. You could look at them with an oscilloscope. One of the things that it used to do to make stuff work was to encode control stuff in band. This is sorta like put

It's a nifty theory, but unfortunately, it isn't true. If it were used for that, there would be wear at the bases of the little knobs as the yarn rubs along it. None of the dodecahedrons we have show any wear in those areas.

this turned into a larger rant than I wanted it to be. But I need to let it out every now and then. Feel free tos kip it. IMHO programming languages are, for the most part, designed such that a compiler's job is easy if you want to com

No. First of all, if an undocumented person commits a crime, they're not going to just let them go because they didn't have a birth certificate or passport or a documented name. They'll charge you, try you, and convict you sa

It's only binding in that district. So here's how the loophole works. There are 12 courts of appeals. You (ICE) does a bad thing. (renditions a US citizen to an El Salvador concentration camp without due process) You get sued, app

The proliferation of Electron apps is one of the main things. Discord, Teams, Slack, all dogshit slow. Uses over a gigabyte of RAM, and uses it poorly. There's a noticeable pause any time you do user input; type a character, click a bu

Usually the attacker, on their own computer, or some other server they have root on, will open a port and expose it to the internet and listen. The exploit payload will then make an outbound connection to that port. Once it's connected

Video encoding is two domains. And there's surprisingly little overlap between them. You have your real time video encoding. This is video conferencing, live television broadcasts. This is done fixed-function not just for power efficie

I recall the legendary Celeron being the 300A. It was 300MHz, but was easily overclocked to 450MHz. There were higher clocked versions, but regardless of which CPU you got, they ultimately were only able to overclock to about the same frequ

Surely we accept unary minus as one of our functions? Once we accept one unary function we're just quibbling over details. I agree that you need to define and agree upon a finite set of allowed operations before playing the game. IMHO,

Kolmogorov complexity is uncomputable because it admits Turing complete languages, and reduces to the halting problem. If the language you admit isn't Turing complete, then the Kolmogorov complexity of the thing is computable. It looks

Correct. You can get the same power with half the voltage by doubling the current. The trouble is the wires. A given wire gauge is limited in its ability to conduct current , not power. So if you double to the current, you'll need to

I'm curious about this too. I would expect any RISC architecture to gain relatively little from a loop buffer. The point of RISC is that instruction fetch/decode is substantially easier, if not trivial.

That's just how particle physics research works. You build a detector that is designed to detect things with specific properties. You run the detector. Did you find the thing? If so, great, if not, well, that's the way the cookie

Some of us do need the real world-ness though. IMHO there should be two versions of linear algebra. One for computer science majors and one for mathematicians. I regularly run into stuff at work where I say to myself, "self, this is

It's actually really important that uniform_int_distribution is implementation defined. The 'right' way to do it on one architecture is probably not the right way to do it on a different architecture. For instance, Apple&#x27

Attempts to prove BB(5) would have begun long before theorem provers were around. This BB was discovered in 1990, and all machines of size 5 would have been enumerated not long after.

You can also glob with c printf style format. ffmpeg -framerate 30 -i image-%05d.jpg -c:v libx265 -crf 35 -pix_fmt yuv420p timelapse.mp4 Will get images of the form image-00000.jpg, image-00001.jpg, ... image-99999.jpg.

You appear to be correct. Clang does not devirtualize in LTO, but GCC does. Personally I consider this very strange. $ cat animal.h cat.cpp main.cpp // animal.h #pragma once class animal { public:
