While browsing in a favorite bookstore with my son, I spotted a display of horoscope themed Christmas tree ornaments. The ornaments were glass balls embossed with golden birth signs like Aquarius, Gemini, Cancer, et cetera, and a descriptive phrase that “summed up” the character of people born under a sign. Below my birth sign golden … Continue reading SWAG a J/EXCEL/GIT Personal Cash Flow Forecasting Mob

Cutting the Stinking Tauntaun and other Adventures in Software Archeology
The other day a software project that I had spent a year on was “put on the shelf.” A year of effort was unceremoniously flushed down the software sewer. A number of colleagues asked me, “How do you feel about this?” Would you believe relieved? This is not false bravado or stupid sunny optimism.

Fun with Farsi Text in LaTeX
