i dunno about #ipv6 ... i just spent the better part of 3 days simply trying to sort out how it works. i think the issue is trying to translate it into #ipv4 speak. #networking #linux #freebsd

Getting somewhat closer to releasing a new version of #swad. I now improved the functionality to execute something on a different worker thread: Use an in-memory queue, providing a #lockfree version. This gives me a consistent reliable throughput of 3000 requests/s (with outliers up to 4500 r/s) at an average response time of 350 - 400 ms (with TLS enabled). For waking up worker threads, I implemented different backends as well: kqueue, eventfd and event-ports, the fallback is still a self-pipe.

So, #portability here really means implement lots of different flavors of the same thing.

Looking at these startup logs, you can see that #kqueue (#FreeBSD and other BSDs) is really a "jack of all trades", being used for "everything" if available (and that's pretty awesome, it means one single #syscall per event loop iteration in the generic case). #illumos' (#Solaris) #eventports come somewhat close (but need a lot more syscalls as there's no "batch registering" and certain event types need to be re-registered every time they fired), they just can't do signals, but illumos offers Linux-compatible signalfd. Looking at #Linux, there's a "special case fd" for everything. Plus #epoll also needs one syscall for each event to be registered. The "generic #POSIX" case without any of these interfaces is just added for completeness

Universal Flash Storage Host Controller Interface (UFSHCI) driver for #FreeBSD coming soon -- currently in review: https://reviews.freebsd.org/D50370

For those coming to BSDCan (bsdcan.org) next week long term forecast looks like it should be ok Wednesday but possibly a tad moist if you are flying in on Tuesday.

Why is #ZFS on #FreeBSD so awesome!!

Wanted to re-partition my SSD to increase swap space.

<add USB HDD>
# zpool add mypool <hdd>
# zpool remove mypool <ssd>
(wait a while as system copies at full speed)
# <re-partition>
# zpool add mypool <ssd>
# zpool remove mypool <hdd>
(wait a while as system copies at full speed)

The final partition is smaller. No problem as long as all the data fits.

And no down time. It is just a bit slower because of all the IO.

FreeBSD is finally getting a useful (MIT) Kerberos implementation in the base system: https://cgit.freebsd.org/src/commit/?id=7f2fe78b9dd5f51c821d771b63d2e096f6fd49e9

no more messing around with Kerberos from ports (so you have two copies of kinit, kadmin, …), or dependency loops like krb5 -> openldap -> krb5.

plus we'll have support for newer ticket algorithms than aes256-cts-hmac-sha1-96 (!)

Opened review for #FreeBSD Bug 287268 on Phablicator as Differential Revision D50697, which adds latest New Feature Branch (NFB) of #nvidia #GPU drivers as x11/nvidia-driver-devel, x11/linux-nvidia-libs-devel and graphics/nvidia-drm[|-510|-515|-61|-66]-kmod-devel.
Once accepted and landed, it would track the latest version of whichever NFB or Production Branch of drivers. Beta Branch of drivers wouldn't be tracked.

Minor #FreeBSD upgrade annoyance: upgrading from 13.4 to 14.3 lost my audio mixer settings, and in fact mixer(1) works completely differently from how it used to. Still trying to figure out how to get line-in levels comparable to PCM output.

seeing the dev summit streams appear in my yt feed gives me feelings

Installing and exploring a new operating system (FreeBSD) has led me to revisit an old and friendly window manager: Openbox

Its an excellent foundation for crafting a lightweight and delightful FreeBSD desktop just the way I like it!
