Jails are a general mechanism to run multiple userlands on one kernel. They started with a change root directory, an IPv4 address and no access to anything dangerous (e.g. /dev/mem). Jails grew a lot features with the biggest bump

If your pool is layed out in a beadm compatible way you can use beadm. Otherwise just snapshot your root dataset recursively and rollback the whole pool in the unlikely case that the update fails. Once the upgrade succeeded (including the n

Just run `pkg install -y xdm` and enable it in /etc/ttys to have init (re-)start xdm on the ttyv of your choice.

Running on such systems keeps the developers honest. No mass produced CPU implements as aggressive visible memory access reordering as Alpha AXP CPUs and SPARC faults on unaligned memory accesses while other platforms "just" take

I wonder if Apples acquisition of acunu.com is finally paying off. Is this file system based on stratified B-trees?

RSA with DHE or ECDHE is a sane handshake. I would avoid DSA and ECDSA based key exchanges because they fail catastrophically with bad random number generators. For most APIs session caching is more important than a faster initial handshake

Most tar implementations default to the first streamer (e.g. sa0) instead of stdout.

On UFS soft-updates have a lower overhead than soft-updates with metadata journaling. The downside of soft-updates without journaling is that it requires a background fsck to recover leaked space after unclean shutdowns. I prefer UFS2 SU (

Btrfs has a broken by design on disk format. Btrfs went with self describing checksums inside blocks instead of a Merkle-DAG with a round robin root. In doing so they ignored existing research at the start of the btrfs project and the only

FreeBSD 8.4 is supported until 2015-06-30. FreeBSD 8.0 was released on 2009-11-25. Odd numbered minor releases and the last minor releases in a major release are supported for 2 years. Migration two newer minor releases of the same major re

The VIA C7 AES implementation could keep up with memory (ca. 20Gb/s). With suitable cipher modes you can use multiple pipelined units in parallel with negligible overhead.

You missed the point of Mosh. SSH transfers a bidirectional stream of bytes between server and client. It uses TCP as transport. You can combine SSH with tmux to preserve your sessions as tmux sessions. If you use SSH to access your tmux se

FreeNAS was suffering from technical debt because it was build on the code base of a firewall appliance for small CF cards. The project initiator gave up on it and it needed a rewrite. Most active contributors had a Linux background and wan

I can recommend gatling by passing firewalls on port 443. It waits 2 seconds for a HTTPS request before it starts OpenSSHd in inetd mode.

Let's assume you use multiple routing tables (FIBs) wouldn't be nice to have the resolve.conf be a variable symlink dispatching on the processes default FIB instead of having to put processes into chroot environments (or jails)?
