A Return to LaTex
When I started writing the documentation for Tali Forth , it was in plain ASCII. Quick to write, but it looked like crap. Then I switched some stuff to Markdown , and for a while, I convinced myself it looked better. Maybe it did. But last week, I had to ad...

So of course Forth has already been ported to the RISC-V
Well, that didn't take long. There is a first experimental native-code port of Forth --  Mecrisp Forth , to be exact -- to the RISC-V (RV32IM), as the German Forth  group Forth e.V.  announced on Tuesday (in German). You can find it on the download page as ...

ALPHA version of Tali Forth 2 for the 65c02 released
Hence plan to throw one away; you will, anyhow. -- Fred Brooks, "The Mythical Man-Month" Yeah, so that really wasn't the original plan. But the first version of Tali Forth , the first Forth I ever wrote, turned out to be so horrible under the hood that in t...

So this guy is building his own RISC-V CPU
Did I mention RISC-V in the last posting? Turns out that Robert Baruch is building his own RISC-V CPU [YouTube] out of chips. The LMARV-1 (Learn Me A Risc-V, version 1) is a RISC-V processor built out of MSI and LSI chips. You can point to pieces of the pro...

Current projects: arc_summary3.py and Tali Forth 2
One of the strange things about getting older are the curious and somewhat uncanny attacks of self-discipline. These days, instead of my usual rushing off and doing three, four, five projects at once, which then each proceed at a crawl, I have managed to cu...

A slight change of focus
Fair warning: Since the Übersquirrel is as built as it will probably every be -- it turns out that software is easier to fit into my life than hardware -- I'll be repurposing this blog for more general ramblings about computer projects. There will still be ...

So after a few months of using ZFS on the new FreeNAS box, I've moved my /home on the Ubuntu machine to ZFS on Linux, and my main gripe is very simple: Why on Earth didn't I do this earlier? It's as people say, after ZFS, other file systems seem depressingly primitive. Yes, it needs at least two disks to really do it things, but storage is cheap. If anything, the large amount of RAM the ARC needs is a problem.

(Still going to go with Linux instead of FreeBSD though - multiseat is now trivial on Linux thanks to systemd, and there is no Steam client for FreeBSD that I can see.)

That the current administration would approve Signal for official use came as somewhat of a surprise.

Eleven bills designed to alter science-education standards have been proposed this year across the United States. A handful of those measures have either abandoned the traditional academic freedom model for more roundabout methods, or are using watered-down versions of it.
