Some printers, like the one I have (HP 8600 Pro), have “Print-to-Folder” capability. Unfortunately, I have no Windows server, only a FreeBSD box to print to. I can mount folders from the FreeBSD box on my MacBook.. if I can get files to scan there. So, to do that, I need a Samba…
I recently had a reason to parse a large data set, for another project. I decided that an ideal “large data set” would be my Outlook mail saved archives. Sadly, Outlook for Mac doesn’t output PST files, it outputs OLM archives, which are, essentially, giant zip files full of XML. I was coding this all…
I’ve updated the u-boot bootloader for Crochet-FreeBSD Wandboard to 2014-10, from 2014-07. The updated image is here, and the boot log is here.
This build is for FreeBSD-11, Alpha 2. Binary image, and bootlog.
Every IT geek is, to some degree, fascinated with the Apollo program which put a human on the moon for the first time. Naturally, there is also curiosity about the computers on the Apollo moon lander, and the software that ran on them. The source code that went to the moon is available now, and…
Recently I had reason to get interested in process modelling. Ultimately I ended up writing an Antlr4 grammar for Modelica (here), but in the mean time I came up with SML (Simple Modeling Language). The Antlr4 grammar is sml.g4. The characteristics I wanted in my own modeling languages were: Ability to define models as text files…
Unix version 0 was written in 1963 by Ken Thompson, on a PDP-7. Recently, the source code code Unix V0 has been discovered, and you can read it here, as pdf scans of printouts. You can read about the discovery, and the effort to boot Unix V0 on a real PDP-7 here. The project home…
I’ve been interested in RIAK for a while, and ORM’s are nothing short of fascinating. I decided to try writing an ORM for Riak, and the results are here: https://github.com/teverett/cbean My ORM is not an ORM of course, because RIAK is not relational. However it is ORM-like; I can store POJO’s and retrieve them. The…
In general, I install QEMU on my Macbook using MacPorts. However I recently had a need to get the tip of the QEMU development tree. Getting the QEMU source tree is trivial: git clone git://git.qemu-project.org/qemu.git I needed an updated version of dtc: git submodule update –init dtc The build instructions from the README are: mkdir…
I’ve tried a couple different mp3 taggers to tag my mp3 library, however, most seem to have trouble with large mp3 libraries. So, after doing some reading about AcoustID and MusicBrainz I decided to quickly code up my own tagger, MusicBrainzTagger. MusicBrainzTagger is a command-line application which recurses a directory of mp3 files and tags…
