Reminder: "OS : The underlying overhead of computation"is happening tomorrow night with NYCBSD. Go if you can.
There will be pizza pie, and Raspberry Pi, for installing BSD, at the next KnoxBUG meeting, tomorrow, for those near Tennessee. Note that it was originally scheduled for Tuesday and had to be moved up a night because of a conflict - so your schedule has changed even if you were already planning to go.
Not as many reading links as usual this week, but lots of BSD news yesterday. It ebbs and it flows.

Done all at the last minute.

Apparently there's a quirk to the way Ricoh cameras format memory cards that made them unreadable on DragonFly. They're readable now. I link this not because I think it affects many people, but because it's such a strangely specific problem.
This week's BSDNow episode is all over the map this week, talking about Unix philosophy (that's where the silence part comes in), tmux, and even Minecraft.
A note from Sepherosa Ziehau explains how you can check for Intel Turbo Boost effect on DragonFly, or at least see your current frequency if you're using AMD.
The question of using vkernels(7) in a manner similar to jails pops up time and again, and the answer is, unsurprisingly, "it depends". It looks like when you want to isolate greedy programs, vkernels are the way to go.
Thinkpieces, this week.
- The Magic Arrow: A talk about the SIP2 protocol and the purpose of REST.

- "Any good recent books?" You all know about these, right? I've mentioned them enough?
BSDNow's episode of the week has a number of Raspberry Pi-specific items, plus a discussion of iocage which I was not familiar with.
The DragonFly installer now supports UEFI directly. There's a uefi(8) man page now, and there's even rconfig support, though not enough people realize how awesome rconfig(8) can be.
I had a spurious carriage return in the RSS feed output that some I think xerxes based RSS readers like spaRSS didn't like. It's fixed now - can someone else running spaRSS confirm in a comment? Or just confirm that you aren't getting RSS errors now if you were for the last few days.
SemiBUG has a meeting tomorrow, and Craig Maloney will be talking about Ansible. Patrick McEvoy may be streaming the proceeds, too. Are you near Detroit? Then go!

- KnoxBUG is having a Raspberry Pi installfest on 01/31. I'll post a reminder.
- KnoxBUG is also planning an OpenRC talk in February, though no date yet.
- And here's the writeup from the most recent KnoxBUG meetup.
- People in NYCBUG are looking to have a classical code reading group set up - no date yet, but it sounds fun. (This has happened before as a one-shot event.)
- Craig Maloney is speaking about Ansible at the next SemiBUG meeting, this Tuesday. This meeting may be streamed. I'll put a reminder up on Monday, too, and link to the stream if I know it.
The ncv(4), nsp(4), and stg(4) drivers are now removed from DragonFly. So is the portal file system. Also, though not a removal, vm.swapcache.use_chflags now defaults to 0. Does this affect you? Almost certainly not! I feel compelled to point it out, though, just in case there's that one person who didn't want a surprise.
This week's BSDNow has extended notes about FreeBSD and lld, the LLVM linker, plus notes on the NetBSD scheduler, OpenBSD changes, and so on. It's very ecumenical.
The i915 driver has been updated to match Linux 4.6 - this is of most benefit to the owners of newest hardware, but the commit message lists what has changed, for owners of Haswell series GPUs and later.
If you are on DragonFly -master, now is a good time to update. Matthew Dillon has been changing how DragonFly handles locking and memory use, with differences in the vmstat structure and page coloring, some memory settings, and many other locking changes. I am only linking to a few examples. If you don't want to dig through those links for performance numbers, he summarized his changes and their effects in a post to users@.
