Šai sadaļā vari iepostēt kādu savu domrakstiņu vai kādu citu materiālu publicēšanai bug.lv.
Arī web norādes, kuras varētu citiem BSD lietotājeim būt noderīgas varat darīt citiem zināmas šeit(iespējams pieliksim arī norāžu sadaļā).

man ljoti patika shis.

I have become very exciting about our light weight kernel threading technology, in particular the methodlogy we are adopting to serialize data access by partitioning major subsystems into threads instead of serializing data access with mutexes (FreeBSD-5 and Linux use a mutex-centric model, DragonFly uses a thread-centric model). The reason for this excitement is that it is becoming clear to us that we can develop very clean-looking, elegant, debuggable, SMP scaleable software using this model whereas using the mutex model generally results in much less elegant (even ugly), difficult-to-debug code. Code complexity and code quality is a very important issue in any large piece of software and we believe we have hit on a model that directly addresses the issue in an SMP environment without compromising performance.

un code kvalitaate liidz ar to stabiliteete, man kaa programmerim arii liekas ljoti svariigi!!! :)
