libjwt available in ports?

Hi @misc, is this library [1] available in ports? I could not find it and the API is very volatile. It's in current Debian stable but the API there already is outdated as well. Would it make sense to port it to OpenBSD? How to deal with developers providing such libraries breaking API/ABI with eve

malloc_trim(3) alternative in OpenBSD?

Hi @misc, does OpenBSD provide something equivalent to Linux' malloc_trim(3)[1]? I am yet to port an application from Linux to OpenBSD and that application is making use of malloc_trim(3). I removed the calls to malloc_trim(3) from that application while still running on Linux and it seems it real

Need some advice on C semantics.

Hi @misc, is there something specific for OpenBSD like style(9) but for semantics? I understand that style(9) is all about syntax. As a long term Java developer having lost all interest in Java, I am searching for something like PMD, Checkstyle etc. for C and rules OpenBSD developers tend to adher

How to parallelization

Hello everybody, as a long time (decades) Java developer now converting to bare metal C, I would like to ask about how to do parallelization properly. The poor man's approach the Java APIs implement pretty much resemble what every one else is doing. Take the number of processors available in a sys
