funny how they use what they already have to make sure others cant have that thing,
...that they never produced in the 1st place.
ie: using their wifi to jam #signals so the rest of us cant have #wifi
isnt that also a #wasteful use of #resources?

The next release of #swad will probably bring not a single new feature, but focus on improvements, especially regarding #performance. Support for using #kqueue (#FreeBSD et al) to handle #signals is a part of it (which is done and works). Still unsure whether I'll also add support for #Linux' #signalfd. Using kqueue also as a better backend for #timers is on the list.
Another hopefully quite relevant change is here:
https://github.com/Zirias/poser/commit/798f23547295f89fa0c751f0e707c3474b5c689c
In short, so far my #poser lib was always awaiting readiness notification (from kqueue, or #epoll on Linux, or select/poll for other platforms) before doing any read or write on a socket. This is the ideal approach for reads, because in the common case, a socket is NOT ready for reading ... our kernel must have received something from the remote end first. But for writes, it's not so ideal. The common case is that a socket IS ready to write (because there's space left in the kernel's send buffers). So, just try it, and only register for notifications if it ever fails, makes more sense. Avoids pointless waiting and pointless events, and e.g. with epoll, even unnecessary syscalls.

В этом посте я опишу, как настроить современную маршрутизацию и использовать Signals для реактивного отключения выбранных ссылок.
Of course, this new credentials checker in #swad needs a #tool to edit these #password files, that's currently work in progress.
I just implemented the class for reading a password, pretty simple thing from a pipe, but an "interesting" job from a #terminal. Turns out doing that portably, reliably and secure needs quite some code.
There's #getpass, but that's deprecated for good reasons (global state and not perfectly clear how it deals with #signals that could interrupt the input). And there's the sane replacement #readpassphrase in *some* systems (e.g. #FreeBSD), but that's not portable.
So, plain old #tcsetattr it is, with some signal handling on top:

Fixed cancelling a thread job in #poser's #threadpool. Using a semaphore to do this seems reliable
Oh my. #Multithreading, #synchronization, async #Unix #signals, this is pure "fun" ...

Academic consensus question on #Signals safety
TL,DR: YES 100%
Signal, a messaging protocol known for its end-to-end encryption, is widely regarded as secure. It is used by popular applications like WhatsApp and Facebook Messenger, serving over a billion users. The protocol includes advanced security features such as "future secrecy" and "post-compromise security," achieved through a technique called ratcheting, which updates session keys with every message sent" #thread (1/4)
The Fourier Transform is a mathematical operation that transforms a function of time (or space) into a function of frequency. It decomposes a complex signal into its constituent sinusoidal components, each with a specific frequency, amplitude, and phase. This is particularly useful in many fields, such as signal processing, physics, and engineering, because it allows for analysing the frequency characteristics of signals. The Fourier Transform provides a bridge between the time and frequency domains, enabling the analysis and manipulation of signals in more intuitive and computationally efficient ways. The result of applying a Fourier Transform is often represented as a spectrum, showing how much of each frequency is present in the original signal.
\[\Large\boxed{\boxed{\widehat{f}(\xi) = \int_{-\infty}^{\infty} f(x)\ e^{-i 2\pi \xi x}\,\mathrm dx, \quad \forall\xi \in \mathbb{R}.}}\]
Inverse Fourier Transform:
\[\Large\boxed{\boxed{ f(x) = \int_{-\infty}^{\infty} \widehat f(\xi)\ e^{i 2 \pi \xi x}\,\mathrm d\xi,\quad \forall x \in \mathbb R.}}\]
