TRIM by default
The TRIM operation has been in DragonFly for some time, and it looks like most SSDs support it reliably, now – so it’s on by default.
GridGenerator on DragonFly
I have been meaning to post this for a while: gridgenerator.com, a painting web app, is running on DragonFly. I was told this on IRC and of course lost all details since then, but that’s fine – go draw something!

In Other BSDs for 2018/08/11
Overflow that I couldn’t catch up to before last weekend’s In Other BSD’s posting time. I try to always have these by 9 AM Eastern time Saturday. (Same for Lazy Reading on Sunday) I mentally imagine everyone sitting down with a drink and nothing else to do but click links, those mornings. At least, I hope that’s wh [...]
Booting and i915, a reminder
A reminder: you need some loader.conf changes if you are booting with EFI/i915.

BSDNow 258: OS Foundations
BSDNow 208 showed up a bit early this week: Among the normal news articles about technology and BSD conventions are notes about how HardenedBSD is setting up their non-profit board. I like seeing that sort of governance documented as it’s happening; it’s the right way to inform people.
LibreSSL 2.8.0 Released

More DRM updates
Francois Tigeot has been quietly updating DRM support in DragonFly, matching Linux kernel 4.7.10. I don’t think there’s any user-visible changes at this point, but I wanted to draw attention to the work.

For future reference, this is the knew server. It runs a few jails, including Bacula regression testing services.

ed25519 support in pam_ssh
As part of a recent update to OpenPAM, you can now use ed25519 in pam_ssh. My perception is that ed25519 is one of the better options to pick.

Ravenports: Status update and the Dra...
The eerielinux site has a followup on Ravenports, which digs into something I’ve covered a bit here: Ravenports is technically excellent and a better choice than dports in many ways – but Ravenports needs more ports. How many more? Probably not very many…
Speaking of which: Ravenports is kept vigorously up to date.
