Asynchronous programming typically involves the use of context-local
state variables, e.g., threads can use thread-local storage. In my
consult-dash emacs package, results from multiple searches were
collected into a single state variable for further processing. The
state variable would have been created on the heap in languages such
as C, and a reference passed along to any asynchronous calls,
typically via a
void pointer in C. Each invocation of the
asynchronous procedure would create a new anonymous state, which
should then be destroyed by the consumer of the result of the
Building Lucas Chess from source on Fedora 35+ is fairly straightforward, but requires a couple of minor tweaks. The sources themselves, not the binaries, can be found on github; the linux binaries are built using Docker for Debian, but most of the dependencies are present in the Fedora repositories....
Adding a new interface to an existing VyOS instance will typically require adding firewall rules for that interface. Here's a checklist:...
Setting up multicast reception on Fedora 34 requires using
firewall-cmd to allow multicast traffic through firewalld via rich
rules. The following is a description of a debugging session (or two)
that helped identify the problem.
