New steps for vendor import
Aaron LI’s updated the development(7) man page to account for new steps in vendor import.
Full history of DragonFly, documented
Aaron LI managed to graft FreeBSD code history onto the DragonFly BSD git repository, and he’s documented how he did it. So, you can follow DragonFly code all the way back to 2003, and then FreeBSD code all the way back to… I’m not sure how far back it goes, but it’s in his merged …

Lazy Reading for 2020/03/29
Accidental open source ideas or maybe history this week. That might be too easy a category to fit into. Panel Syndicate, online comics. (via Warren Ellis) Mastermind at 50. And its impact on early computers. (via) Opensource.builders. Alternate apps. (via) Awesome-Selfhosted: “A list of Free Software web applications which can be hosted locally”. (via) Text-Based …
In Other BSDs for 2020/03/28
I have multiple BSD based systems to update, reboot, and hopefully not physically visit in the next week or so. pfSense 2.4.5-RELEASE Now Available. Booting [OpenBSD] from an FFS2 filesystem. [packages] Retiring Python 2 support in IPython. AnsiMail, based on ansible, not ANSI as older folks may immediately think. (via) Valuable News – 2020/03/23. Bob …
Flame graphs on DragonFly
Flame graphs are a way to see what code paths are most used in a stack trace. DragonFly now has a flame_graph utility.
BSD Now 343: FreeBSD, Corona: Fight!
BSD Now 343 is quite topical this week: viruses and VPNs. Release information, etc., too.
Booting from an FFS2 filesystem
Developer Otto Moerbeek (otto@)
has
been
working
on
support
to
boot
from
FFS2. He writes in with the below article, to give us a little insight into the challenges he faced while working on this.
FFS2 filesystem support has been in Open…
jails and loopback IPs
Jails on DragonFly can now route to loopback addresses (i.e. 127.0.0.1). Because of this, they can work like shared IPs and the jail can connect to the host. I think this means that you no longer have to bind jail services to specific IPs as you did previously. Don’t quote me on that; I’ve run …
Optimizing memory operations
On EFNet #dragonflybsd, Matthew Dillon and ‘mjg’ have been discussing various way to optimize for bulk builds. A recent update from mjg for different memory functions shaved 1.7% off bulk build time – significant, when you are talkin…
Bob Beck Interview from EuroBSDCon 2018
I had the pleasure of
sitting with Bob Beck
at EuroBSDCon
2018 in Bucharest and asking him some questions about the
OpenBSD Project, its approaches and some of his favourite
aspects of the Operating System and its projects. Bob
patiently outline…
i915 drm update again
I didn’t read far enough ahead in my backlog, if that makes sense. i915 has another update, to 20160808.
Lazy Reading for 2020/03/22
Random this week, but that’s not so different than usual. Bach’s prelude in C major written in sed. (via) Kill the Newsletter!, newsletter to RSS converter. (via) 100+ legal, free literature download sites. Katherine Cox-Buday Uses This. Someone who thinks hard about their setup. ARM-ed Mac: Not Again Or For Real This Time? Written by …
In Other BSDs for 2020/03/21
A bit short this week; I think everyone’s been occupied with other issues. How to Configure the WireGuard VPN Server in OPNsense. (via) ssh with 2FA. The growth of command line options, 1979-Present. Technically BSD cause of the history. (via) New FuryBSD 12.1 based images are available for XFCE, and KDE. Valuable News – 2020/03/16. …
BSD Now 342: Layout the DVA
For once, I couldn’t figure out what the name of this week’s BSD Now episode referenced. It’s Data Virtual Address, in ZFS, which gets covered in the show. There’s a specific bit about Go and OpenBSD that I haven’t seen…
