We've recovered another UNIX distribution that hasn't been seen in almost 50 years!

This is UNIX Program Generic Issue 3 from 1977-04-12. It descends from V6 and evolved into System III. We thought it didn't survive, but it turned up in some tapes @bitsavers read yesterday!

You can run it in SIMH with scripts I wrote, browse the sources in the Unix Tree (thanks Warren!) or from a tar, or read the Program Generic documentation (thanks Matt!).

Software is shaped by hardware and vice versa.

If you build your software so it needs a GPU, a TPU, or an internet connection, then you are implicitly selling that hardware. Manufacturers profit off the free advertising. Sometimes this drives people to the sellers you might not like.

The way we create can be a form of activism. Choose to write smaller, simpler, more portable code.

Haha, the old vi book (Learning the vi Editor, 5th edition) is teaching me new tricks. Or at least, reactivating parts of my brain that had those tricks buried.

:g/^{/-1 p

will display the names of all the functions in this C file... if it's formatted to BSD conventions, with a single «{» on a line of its own between the function prototype line and the body of the function.

NetBSD turns 33 this Sunday! 🚩

To celebrate 33 years of clean code, portability, and zero bloat, Challenging the rest of the fediverse to help hit this year's funding goals.

Also do drop a screenshot of your uptime, uname -a, or a pic of the weirdest hardware you've got running NetBSD right now. (RockPro64 NPF routers or Pi's hooked up to retro CRTs highly encouraged).

Throw some money at the developers keeping the real UNIX alive:

The funny thing is that (IIRC, according to Thompson) #UNIX originally started out as a way to experiment with filesystems.

So, it's basically an OS that grew around an fs. XD

Tho, A) pipes are super concise, cat foo|sed 's/bar/quux/g'>foo2 is *amazing*.
Writing that in complex languages, and with handlers & exceptions, is much more
verbose so you woulnd't do it.
B) Pipes are bidirectional. You can do myrobot.sh|ed which does a bunch of commands interactively.

The gist is a clock that chimes (cuckoos, here, I guess) harnessing the power of conditions.

I think this sm0l article indicates that ansi common lisp condition handling is a more powerful expression of but similar to unix pipes; look at what modifying the handlers does and is like in the article.

SADLY I am not available for the #lispyGopherClimate sundaymorningineurope.

An appointment was made without asking me.

Something that I'd love to be able to do, but haven't figured out how, yet:

You can run somecommand 2>&1 > log.txt to get STDOUT and STDERR together, but you won't know which is which.
You can run somecommand 2>err.txt >log.txt to get STDOUT and STDERR separate, but you won't know the timing, or which error messages happened between which STDOUT messages.
I'd like to figure out some way to combine both, so you end up with a file like this:

1: this was a STDOUT message
1: this was a STDOUT message
1: this was a STDOUT message
2: this was a STDERR message
2: this was a STDERR message
1: this was a STDOUT message
2: this was a STDERR message
1: this was a STDOUT message
1: this was a STDOUT message
1: this was a STDOUT message
1: this was a STDOUT message
1: this was a STDOUT message
2: this was a STDERR message
2: this was a STDERR message

Is it just me being oblivious, or when did info-zip start to require
export ZIPOPT="--temp-path $TMP"
to make it use somewhere other than next to the source file (which may be in a protected location)?

It doesn't do that on my old Mac, it dumps temp files in /tmp or something.

Found an interesting story about the origin of the SGI logo while reading IRIS Universe, Spring 1987 issue..

Puzzle artist Scott Kim designed the Silicon Graphics logo entirely using JAM, a pre-PostScript language from Xerox. He started with a cube, looped a continuous tube around its vertices, rounded the corners, then rotated it so the 2D projection reads as both a hexagonal flower and a 3D object.

@flexion have you seen this?

Finally, I managed to install and configure a graphical environment directly during a #FreeBSD installation session 🎉

Most of the friction was around GPU drivers, but the feedback and suggestions I received were incredibly helpful. A lot of people want to use FreeBSD on their laptops and desktops, and that really shows.

For now, the goal was to provide a simple option to install #KDE Plasma. If there’s interest and more requests, we can definitely expand this in the future with additional desktop environments and options.

Special thanks to the FreeBSD Foundation for their support 🙌

New post: shell tricks that aren't exactly secret, but aren't always taught either.

Split into two sections: what works on any POSIX sh (FreeBSD, OpenBSD, Alpine...) and what's Bash/Zsh-specific. Because not everyone is on Linux with bash as their login shell.

Things like CTRL+W, $_, pushd/popd, fc, set -euo pipefail caveats, and more.

Got my A/UX installation and update discs ready for this weekend to get A/UX installed on the Macintosh Quadra 650. I already have the disk images from which to boot off as well as other disk images for updates to perform post-3.1-update. Gonna create those on the StarMax. 💾 🍎

Not sure if this is compatible with #MARCHintosh, but it will be on a 68K Mac and System 7.1 is used to get that one there, so maybe? ​

I found this ad for a six-degree-of-freedom 3D input device in the Summer 1989 issue of the SGI magazine "IRIS Universe".

I remember seeing stuff like this around in the 90s, but it all seemed so inaccessible at the time. Flipping through these old professional magazines, you spot some interesting engineering and industrial design.

@flexion, you should get one of these, restore it, and get it working on one of your systems.
