user logging changes for DragonFly
last(1), reboot(8), and sshd(8) now log to /var/log/wtmpx on DragonFly. This change will probably, hopefully, be invisible to most people.

excellent article on an involved investigation into a complex issue:
the non-arrival of interrupts for certain touchpad devices.

BSD Now 309: Get Your Telnet Fix
This week’s BSD Now talks about some recent security discussions with telnet and (unrelateD) OpenSSH history, and points to a recent discussion on DragonFly I haven’t even gotten to link yet, cause it’s ongoing.
(telnet is awful but i…
taskset for DragonFly
Nan Xiao needed a taskset tool on DragonFly, so he made one. It’s apparently similar to usched(8).

NetBSD 9.0 release process has started
If you have been following source-changes, you may have noticed the
creation of the netbsd-9 branch! It has some really exciting items
that we worked on:
– New AArch64 architecture support:
Symmetric and asymmetrical multiprocessing support (aka b…
HAMMER2 now default
This slipped in just before the 5.6 release, and I thought I had already noted it: DragonFly now defaults to HAMMER2 for disks during install, instead of HAMMER1.
A ps tip
If you want to see all running threads on your system, grouped by process, with who ran it and how much memory it’s taking, it’s easy: ps -alxRH.
I mention this because it’s easier to remember ‘alxRH’ than it is to find al…

I get indirectly cranky, this week. Dungeon Generation in Diablo 1. Roguelike! (via) Pressing Forward. “The grassroots mechanical keyboard scene”. I did not know about the Hall Effect, or the X1 keyboard, both of which are interesting. sc-im, a terminal spreadsheet. Like Visicalc all over again! Design tools are holding us back. I like the …

Several layers of radeon update
Francois Tigeot has updated the radeon driver in DragonFly to match what’s in Linux kernel 3.19.8. No, wait, I took too long to post this cause there’s been so many things, so now it’s up to 4.4.180.
BSD Now 308: Mumbling with OpenBSD
This week’s BSD Now talks about using a Mumble server on OpenBSD, along with a nice range of other topics.
Am I in jail?
There’s now a read-only sysctl ‘jail.jailed’ that can be checked to see if the current environment is running within a jail; useful for scripts that should not run in that environment, etc. I link to it mostly because it’s an odd sort of meta-signifier of reality, like being awake or in a waking dream, and …
