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.

Valuable News – 2020/03/23.
Bob Beck Interview from EuroBSDCon 2018.
XIGMANAS 12.1.0.4 Ingva Released. Did not know this existed. (via)

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.

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 few jails in my life.

Update: I should have linked this too: the sysctl jail.defaults.allow_listen_override that makes it easier in the host system too.

2020/03/24

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 talking tens of thousands of packages.

i915 drm update again

I didn’t read far enough ahead in my backlog, if that makes sense. i915 has another update, to 20160808.

In Other BSDs for 2020/03/21

A bit short this week; I think everyone’s been occupied with other issues.

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 mentioned elsewhere, too. (see show notes)

Sound and headphone jack tips

If you’ve got a pcm audio device – and you probably do – and a headphone jack – ditto – this thread may help you find the right sysctl to enable it on DragonFly.

i915 driver update in DragonFly

Francois Tigeot has updated the i915 driver to 20160725. What does that mean for users? I don’t know; there isn’t a changelog. But higher version numbers are always more fun!

rcorder cross-pollination

rcorder-visualize.sh draws the dependencies for rc scripts using dot. Originally in NetBSD, then in FreeBSD, now in DragonFly.

ChiBUG meeting, tonight, at a new location

ChiBUG meets tonight, and it’s at the Oak Park Library, not the usual place. Go, if you are near, and especially if you were too far away, before. This spot may be more accessible.
