Joerg Sonnenberger has updated GCC to GCC 3.4.4. Also, Simon 'corecode' Schubert reports his experimental DragonFly system built entirely with GCC 4.0 is working well.
A recent thread about describing DragonFly's kernel led to this post from Matthew Dillon, tying together monolithic kernels vs. microkernels and how they relate to DragonFly's Single System Image future.
David Rhodus's recent blog entry on notes he is most of the way through a "block level journaling system for FFS/UFS". As I understand it, this is different from Matthew Dillon's journaling work - this is the traditional form of journaling, while Dillon's is a mechanism to treat disk activity as a relocatable/rewindable stream.
Things have been quiet on the mailing lists for DragonFly, and I'm in the process of moving house, so news on this page may be intermittent for a week or two...
Simon 'corecode' Schubert has posted his patches for using GCC 4 to compile DragonFly - it works for the world, but not for the kernel, yet.
Normally I don't post about ports that much, but this is a pretty commonly used application: the dfports override for FireFox brings it to the more-secure 1.0.4., thanks to Jeroen Ruigrok/asmodai's commit.
Joerg Sonnenberger has a fix for libtool in pkgsrc that may allow programs like orbit, arts, etc. to compile on DragonFly.(necessart for the Big Programs like KDE)
Robert Garrett has imported NetBSD's newbtconf, a system for choosing the boot environment. See that manpage link for a better description.
Joerg Sonnenberger mentioned some of the gotchas involved in porting a network driver from another BSD flavor.
Joerg Sonnenberger listed a few links describing benchmarks with GCC 4.0, as part of a conversation on why he's working on GCC 3.4.4 instead.
Colin Percival of the FreeBSD Project discovered a security problem with "Hyper-Threading Technology", found on newer Pentium 4 processors, where information from one thread can be read by another. He talked about it at BSDCan 2005 today (wish I was there!), and there's a corresponding security alert for FreeBSD. The FreeBSD securing procedure should work for DragonFly, too.
Matthew Dillon, David Xu, and Joerg Sonnenberger have been having an extended conversation on kernel@ about RTLD, TLS, and other things - look for the "kernel library interfacing layer" topic if you want to browse it. All three of these guys are heavyweight kernel programmers, so it goes in-depth. has a review up of the book "Linux in a Windows World". Why mention this here? Because it doesn't really cover Linux as much as it's covering applications that run on Linux... All of which run on DragonFly too.
I think this has been around for a while, but it was just posted on the GoBSD mailing list: NYCBUG has a BSD Tracker page, where businesses that use BSD can be listed. If that describes your workplace, get on there.
Matthew Dillon has created a subversion for the 1.3 experimental code, in order to deal with the recent changes there, and also moved the RELEASE code up to 1.2.2, to incorporate a recent TLS fix.
