qnx
microkernel
rtos
posix
Third of four portraits of the Unix family, the outsider with
none of the blood. QNX is not descended from Unix and holds no
UNIX certificate, yet keeps the rules more strictly than some
that do. Its microkernel keeps only the core and
turns the drivers out to user space, so a failed one restarts
without a reboot. POSIX-certified, in over a hundred million cars, the
first ASIL D hypervisor. Discipline is a stance, not an
inheritance. Unix Universe ⊣ The Unix Family, 3 of 4.

open-source
sovereignty
Second of three Sundays on what we can no longer read. You
download a model called open, run it on your own
hardware, and hold the finished loaf, not the recipe. The
training data, the compute, the code and the evaluation stay
shut. A 2024 Nature paper calls the shortfall
openwashing; even Mistral's Apache-2.0 flagships grant
the numbers, not the pipeline. Sovereignty is a property of
information, not geography. IT Philosophy ⊣ The Weight
You Cannot Read, 2 of 3.

freebsd
security
containers
openssh
The third and last of Boring on Purpose. When regreSSHion
landed in July 2024, FreeBSD corrected six branches in
five minutes and forty seconds under one advisory;
Linux fleets got a week of scattered ones. That gap is where
the bug lives too: the November 2025 runc break-outs happened
in the seam between kernel, namespaces and runtime,
each part individually correct. One tree leaves no gap to hide
in. Security Review ⊣ Boring on Purpose, 3 of 3.

softwarearchitecture
sqlite
unix
freebsd
The fourth and last of the four breaks, and the close of the
diagnosis. Layering was built to bound complexity,
then quietly shifted to postponing the look beneath
it, so the thing below leaks up and you carry the layer and
the thing at once. Lehman's law explains the tower:
complexity accrues, reduction is unfunded. The counter-proof
is the code allowed to finish, SQLite in one file on
four billion phones, plus awk, sed, make and pf. Lean

bsd
freebsd
openbsd
netbsd
Second of four portraits of the Unix family. The
certified Unixes shared a word; the BSDs share
a code lineage. Four siblings forked from one Berkeley
source and each stayed whole: FreeBSD, whose
jails shipped containers in 2000; OpenBSD,
which gave the world OpenSSH; NetBSD, which
runs anywhere; DragonFly, with HAMMER2. They
forked without fragmenting because each inherited a
base system, one source tree. Unix Universe
