Autoconf can use cache files [1], which can greatly speed up repeated configures. With cache, a test is run at most once.

Here is a non-zero null pointer: https://gcc.godbolt.org/z/Po5r5Pa36

It creates a compound literal [1] of type array of int, and initializes the specified array positions using designated initializers [2] with the results of calls to puts().
Using designated initializers without the = symbol is an obsolete extension.

Even the original version 1507 is still supported on the LTSC channel. Support for UTF-8 manifest was added only in version 1903.

Old does not mean bad. Even a decade later Wayland struggles to provide basic features that were built in the X protocol.
andreyv | 2 years ago | on: Ubuntu 24.04 LTS will enable frame pointers by default
The number of registers available to the program is fixed in the instruction set. The program cannot address more registers without recompiling it to an extended instruction set.

First person shooters. Vertical synchronization causes a noticeable output delay.
For example, with a 60 Hz display and vsync, game actions might be shown up to 16 ms later than without vsync, which is ages in FPS.

You can use systemd-cron [1] to run traditional cron jobs with systemd. No need for a separate daemon anymore.

Instead of "/usr/bin/time" you can also write "command time".
andreyv | 2 years ago | on: Control Center on macOS is always re-rendering its SwiftUI causing 1% CPU load
1% is still a lot for power saving. If the system is idle, it should be at 0%. If it is anything above, then it shows poor design.

Right — ferror() does not set errno, and so perror() is not appropriate here. fprintf(stderr, ...) would be better.
andreyv | 4 years ago | on: Bugs in Hello World
In C, and many other languages, the file stream error state is saved after each operation, so you can skip error checking on every output line and only do
if (fflush(stdout) != 0 || ferror(stdout) != 0)
{
perror("stdout");
return EXIT_FAILURE;
}
In GNU programs you can use atexit(close_stdout) to do this automatically.

Perhaps this: https://docs.microsoft.com/en-us/windows-hardware/design/dev...
> On occasion, the system stays in the active mode (with the screen off) for a longer interval of time. These longer active intervals occur for a variety of reasons, for example, processing incoming email or downloading critical Windows updates.
andreyv | 4 years ago | on: Why “process substitution” is a late feature in Unix shells
> So there is no way to abort a bash script if something like <(sort nonexistent) fails.
The process ID of the last executed background command in Bash is available as $!.
cat <(sort nonexistent)
wait $! || echo fail
sort: cannot read: nonexistent: No such file or directory
failandreyv | 4 years ago | on: Dell removed Fn+Left/Right for Home/End from all its products
Dell also removed trackpoint and all touchpad buttons, and made up/down arrow keys half height on the new Latitude laptops.
These are not the changes one would expect to see in a professional-grade laptop. On the other hand, the Lenovo line looks good in this regard.

Autoconf can use a cache file to speed up tests: https://www.gnu.org/software/autoconf/manual/autoconf-2.60/h...

In fast-paced games it is essential to disable vertical synchronization as well, trading possible tearing for less input lag.
Does Wayland support this?
