I'm not a fan of sports, with one exception. I do love hockey. I love violent dudes skating around smashing shit with sticks. It's just irresistible

@jake4480 @BlackenedGreen
Hockey in Europe is quite different from American hockey, in a way that violence / brutal body checks here are more of an exception rather than a norm. Less physicality and stronger focus on speed, skill and structured team play.
I used to be an Italian inline hockey player (with occasional playing on ice) and can't stress this enough.

Heads-up for Game of Trees (GoT) users on pkgsrc:

  • devel/got-portable has been renamed devel/got, superseding the old
    unmaintained got port [1][2]. pkgin should automatically take care of
    the transition upon upgrade.
  • with the last update (to version 0.95), devel/got will now install the
    got daemon and give instructions on how to set up a GoT server.

musing.

Got a Sun Netra X1 for just 50€ from a private seller in Rome. He offered to deliver it to me personally.

The server came with Solaris 8 preinstalled, but I wanted to have a modern system on it. In lack of an optical drive, I set up a serial console to the Sun LOM, and took up the challenge of installing NetBSD over network, via DHCP/RARP and NFS [1]. (See screenshot).


[1] https://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/202309171840Z/sparc64/INSTALL.html

Internals of the Netra X1 with upper lid removed. You can see the UltraSPARC-IIe CPU (center), 2 PC133 RAM modules (left), the power supply unit (right) and the IDE HDD (front).
Rear view of the Sun Nextra X1, showing (from left to right) the power switch button, the system configuration card reader, the serial A (LOM) and serial B ports, the USB ports (2), the ethernet ports (2) the LINK leds, the fault led and the power led.
Screenshot of my fvwm desktop (workstation) featuring two tiled windows: on the left, a terminal connected to the Netra X1 with NetBSD 9.3_STABLE installed, showing login greet screen, motd and a $(bsdfetch) output, containing valuable information on the running system. On the right, the official guide for the Netra X1 by Sun Miscrosystems in PDF format.

Valuable insight on software portability and obsolescence, by
@sevan

Portable Legacy

"Something I’ve been thinking over on and off for a while, is the meaning
of portability claimed by folks regarding software. Fish out an old
computer with a matching vintage closed source operating system, how
does the portable software fair in such a situation?..."

Woke up this morning curious. For all the users out there, is there a reason for someone running Linux desktop to consider running (of any kind or flavor), or is it more useful to have as a tool for servers? My only previous experience with BSD is brief dalliances with TrueNAS.

@RL_Dane @royal @spaceraser I wouldn't bet on poor performance on OpenBSD being due to mitigations (but maybe SMT off by default?). Many OSs apply the same kind of mitigations.
What impacts OpenBSD performance is a coarse-grained lock in large chunks of the kernel (this is being improved over the years). Then you also have TCP/IP stack and i/o throughput where they don't shine. The project has always prioritized other things, which is a blessing and a curse at the same time.

@RL_Dane @royal @spaceraser
That said, it's not like NetBSD performance is that better (maybe somewhere in between OpenBSD and FreeBSD) . The only BSD which can almost keep up with Linux in this field is FreeBSD. System performance is a complex matter, requires a lot of work, so never take it for granted: https://www.brendangregg.com/linuxperf.html

SectorC is a C compiler written in x86-16 assembly that fits within the 512 byte boot sector of an x86 machine. It supports a subset of C that is large enough to write real and interesting programs. It is quite likely the smallest C compiler ever written.

GNU Guix/Hurd now runs on my x60 (32bit) with full disk support (rumpdisk) and networking support (netdde). Patch sets are underway.

Looking into native guix builds right now.

@fsfe

Picture of the x60 showing rumpdisk diagnostic boot messages.
Picture of the x60 showing root login. There's a small black-and-white image of GNU's Gnu, and the message: "This is the GNU Hurd. Welcome."
Picture of the x60, showing serveral networking commands being executed successfully: "herd start networking", "herd start sshd" and "ssh janneke@dezyne.org".
