If you were wanting to encrypt your /home directory, Pierre Abbat has written up the explicit steps he took to do that very thing.
Week 3 is underway, and the students are starting to get into the meat of their projects: Daniel Flores: HAMMER2 compression feature Larisa Grigore: System V IPC in userspace Pawel Dziepak: Make vkernels checkpointable Joris GIOVANNANGELI: Capsicum Mihai Carabas: hardware nested page table support for vkernels
The pkgsrc-2013Q2 branch has been out for some days, but the official release announcement has now been published, with details on the number of ports. You should be able to pull it down from dragonflybsd.org via git, by the way.
A U.S. holiday and very warm weather has made this a less intense week. At least for links. Someone help. A problem I never anticipated. (via) Git Cheat Sheet. This one’s for printing. (via) Real Life Tron on an Apple ][gs. (via) Neocities, an excellent idea. Follow the suggested links. (Read more...)
The official announcement has gone out. You should be able to pull pkgsrc-2013Q2 via git from dragonflybsd.org within the next 24 hours.
While these aren’t his BSD books, Michael W. Lucas has an interesting post up about the sales on his two recent books, SSH Mastery and DNSSEC Mastery. I’m always interested in seeing how self-publishing models work, whether it’s software or books or music. He points out that the point of his DNSSEC book is to see if a very [...]
All the Summer of Code students for DragonFly have posted their second week reports: Daniel Flores: HAMMER2 compression feature Larisa Grigore: System V IPC in userspace Pawel Dziepak: Make vkernels checkpointable Joris GIOVANNANGELI: Capsicum Mihai Carabas: hardware nested page table support for vkernels There’s a lot of progress for [...]
If you have an Emulex BladeEngine 2 or 3, or an Emulex Lancer, it should work in DragonFly, thanks to Sascha Wildner’s recent commit. Emulex has 10Gb network cards, in case you were like me and not familiar with the name. (You thought I was going to type “Sepherosa Ziehau”, didn’t you?)
Some of the links this week go pretty in-depth. Enjoy! This short story from 1954 might serve as a reason to avoid single system image computing… (via Sascha Wildner) Vim and Ctags tips and tricks. (via) Psygnosis game box designs. Nostalgia for some, neat art for anyone else. (via) 50 years of ASCII, and (Read more...)
FreeBSD ports, and therefore Dragonfly dports, will drop KDE 3.5 items sometime very soon. It’s possible to continue to build them in dports, but it’s extra work. If you need them, volunteer, because otherwise they will be dropped. (An idea I fully support.)
Earlier this week, Daniel Flores posted the first-week report on his Google Summer of Code project, file compression in Hammer. He mentioned that the LZ4 algorithm he is using seems to have the best performance with repeating text data, as in logfiles. I asked for numbers, and he provided them. The important data in the results is the tota [...]
If you have a mps(4) device (LSI Fusion-MPT 2 SAS disk controller), you may be interested in Matthew Dillon’s large commit of bugfixes from FreeBSD. Specifically, he notes that the drive gets ‘overtagged’, and performance can be greatly improved by reducing the number of tags used.
Thanks to Sepherosa Ziehau, Netperf will now calculate Jain’s fairness index. That is a formula that is both interesting and unfamiliar to me. Not that I understand it, of course – it’s just because it has a neat name.
It looks like OpenJDK7 works in pkgsrc for DragonFly, thanks to Ryo ONODERA, and I think it’s working in dports too.
Because Sepherosa Ziehau changed mbstat, anyone on bleeding-edge DragonFly will need to rebuild world, or else netstat will become confused.
Supposedly it’s FreeBSD 9.0 under the hood on the new Playstation 4 systems. What does this mean for FreeBSD, or driver support, or BSD in general, or what you can run on that hardware? Possibly nothing other than a vague sense of superiority. On the other hand, this BoingBoing article makes a good point about commodity hardware and i [...]

Julio Merino is not renewing his membership of the NetBSD board of directors; he wrote an extensive post as to why. I agree with some of the issues he raised; they are possible on any open source project. I don’t necessarily think the solutions he proposes are correct. I am clearly biased on this, but I think NetBSD needs (Read more. [...]
I was going to make excuses for a low link count because of being on the road this week – but somehow I managed to find a lot to read anyway. We all win! Dragonflies with brain-tracking backpacks. Not DragonFly-relevant except for the subject creature. (via) Speaking of the actual bug, my daughter caught a dragonfly for (Read more. [...]
There’s already been some previous conversation about how much longer to support the i386 platform for DragonFly. It looks like PC-BSD will be the first ‘flavor’ of BSD to make the jump. Support for PC-BSD on i386 will be dropped after release 9.2. That includes ‘TrueOS‘, the version of PC-BSD for servers, whi [...]
