The issue is not motion, the vestibular system cannot measure velocity, only linear acceleration and rotation. The only issue is while you are accelerating in a horizontal directio…

Do you maybe know, when frames rendered by GPU 1 (e.g. fast GPU) need to be sent to GPU 2 (e.g. slow GPU doing the compositing and outputting to the monitor), how does the data act…

This is quite unclear to me. Is DMA-BUF so generic that the memory it refers to can be in different types of RAM, including GPU RAM and CPU RAM?

The mention of DMA-BUF makes me suspect that it involves rendered video being copied from the GPU to the main RAM and back to the GPU, which wastes energy. Does someone have detail…

In any case, if the program forks in order to exec, it shouldn't be using fork at all, but posix_spawn. Fork gets more expensive as the virtual memory of the process grows, since i…

Suppose the the period of lights is equal to the time expected to move from one light to the next, and each light is red/green for the same amount of time. You have a green wave if…

Programming languages aren't able to express arbitrary real numbers, so to "determine whether a given real number is representable as an int or not" is mostly meaningless in a prog…

Each floating point value that is not a NaN represents a certain real number, -inf or +inf (this can be expressed in terms of the sign bit, exponent and mantissa). Knowing that, a …

One benefit would be to protect yourself from security issues in the main torrent code. Anyway it was just an idea, not a serious proposal.

You don't always need epsilon. I've written lots of floating point code that works well without epsilon checks. See my comment in this thread (double_to_uint64) how what the OP nee…

This is not right. The current rounding mode is not guaranteed to apply to integer to floating point conversions. Quoting C99, section 6.3.1.4, paragraph 2: "When a value of intege…

Here's a reliable/portable solution: bool double_to_uint64 (double x, uint64_t *out) { double y = trunc(x); if (y >= 0.0 && y If you need different rounding behavior, just change t…

It could be done with a local TCP / UDP WebSocket gateway, especially if it's written in a safe language like Rust.

See my sibling comment, that should make it much better.

Two more about.config: - gfx.webrender.all = true (important on Linux, fixes jerky scrolling) - general.smoothScroll.mouseWheel.durationMaxMS = 200 (makes mouse scroll animation fa…

Plasma/KDE is mostly great, but a major thing that GNOME and Xfce still do better is GVFS and GVFS-FUSE. That means I can browse to smb://something or sftp://something, double clic…

Or at least the basic double-slit experiment with snakes. WILL the snakes form an interference pattern?

Also, more SW programmers should be getting into this field, as by working in SW first you realize all the things that need improvement in the FPGA world (which the FPGA people did…

> -march=native and -mtune=broadwell tell the compiler to optimize for your architecture. One would think given the compiler documentation that march implies mtune, but this is app…

I only use my alarm clock in addition to my phone when I must not miss something really important.

GCC has had this since forever: cc: internal compiler error: Segmentation fault (program cc1) Please submit a full bug report, with preprocessed source if appropriate. See for inst…

Paid 13200 USD (they don't publish the price on their web page any more, but I suppose it didn't change much). Supposedly their price is one of the lowest (and you get the best car…

Hope you're better. I had a similarly horrifying experience myself. More and more pain pretty much everywhere, tiredness, headaches, GERD - almost every "vague" symptom you could t…

I could argue that even people who genuinely feel emotions have, unconsciously, learned to feel them through their interactions with other people. Who can prove to me that emotions…
