I was curious to see how difficult it would be to compile NetBSD on FreeBSD 10. Once you have the source, there is a build.sh script which is very helpful. The build is as simple as: ./build.sh -m i386 tools ./build.sh -m i386 kernel=GENERIC release In my case I have both clang and gcc installed. I…
FreeBSD-11 has support for i2c on Wandboard. The working boot image is here, and the boot log is here. In order to enable it, there were three steps Enable the kernel options Update the files.imx6 file Create the DTS mappings The kerne config for Wandboard-Quad is here, however, most of the kernel options for Wandboard…

Back in the dark ages (the 1980’s), people like myself coded on Apple][ computers. If you were good you coded in Applesoft BASIC or Integer BASIC. If you were really geeky you coded in Assembly language on the 6502 processor. The Apple][ OS was coded in assembly language, so if you really wanted to understand what…
If you haven’t read this book, I highly recommend it. I discovered it in high school and finally purchased my first copy at the now-gone Duthie Books in Kitsilano. Without going into the details of the book, the author uses a simple Peano arithmetic called Typographical Number Theory (TNT) to illustrate some of his points. An example…
I’ve been interested in HTML parsing for a while now. There are a number of reasons to do this, such as: Validating that what claims to be HTML, is HTML Finding every style sheet and script in an HTML file Pretty-printing Syntax highlighting Linting Translating between markup languages, for example generating JSPs from PHP, or…
After FASTA, I got interested in gff3. The link to the grammar for this file is here: antlr/grammars-v4. You can read about gff3 here.
I recently had a chance to learn a little about Bioinformatics, and ended up browsing the NIH’s database of genomes here. Inside the genome data for any particular strain of a species, you’ll find various files with file extensions like “ffa”, “fna”, “ffn” and “frn”. These are FASTA files. If you’d like an example, here’s…
