Here’s a GNU Bison and GNU Flex version of my MMIX assembly language floating point number preprocessor. The code was developed using GNU Bison version 1.875d and GNU Flex version 2.5. This version allows for entering more complex expressions of floating point numbers involving addition, subtraction, multiplication and division. Extending the grammar to cover trigonometric […]Read More → MMIX assembly language floating point number preprocessor – GNU Bison and GNU Flex version
Here’s the code for a C program I conceived during a rather boring night shift while performing national service some years back. The code was later refined using GNU Bison and GNU Flex for parsing the operand field, yielding the possibility of processing whole expressions involving addition, subtraction, multiplication and division. Instead of specifying IEEE […]Read More → MMIX assembly language floating point number preprocessor – initial C version
I was looking at some old files and found these files containing MMIX assembly code. The first file is a program for converting angles from a single value to sexagesimal notation, and back. The second file is a program for calculating the area of a triangle. I have more MMIX code dating back at least […]Read More → dec2dms.mms and tri_area.mms
I’ve put WITH_ICONV=yes in my /etc/src.conf file on a few VMs running stable/9, and yes, I got burned. My beloved server named enterprise running stable/9 was also affected. :-/Read More → FreeBSD and WITH_ICONV

I upgraded some of my virtual machines during my summer holiday. They are all running ZFS, but were neglected for so long that they were still updating their source and ports trees using CVSup. I began pondering how to migrate to Subversion with the least fuzz possible. Luckily, I had anticipated the switch to Subversion, […]Read More → Moving ZFS datasets around eases the transition from CVSup to Subversion
