Taking my headphone amplifier, which was two feet from my iPhone cradle, and moving it to another spot four feet from my phone has reduced the GSM interference in my headphones from “intolerable” to “inaudible”. Which is great, because there’s a paint crew scraping my house prepping it for new paint, and I happen to be working from home this week on a critical project, so I was in desperate need of some sort of auditory isolation.
During the Russian revolution, the mathematical physicist Igor Tamm was seized by anti- communist vigilantes at a village near Odessa where he had gone to barter for food. They suspected he was an anti-Ukranian communist agitator and dragged him off to their leader.
Asked what he did for a living he said that he was a mathematician. The sceptical gang-leader began to finger the bullets and grenades slung around his neck. “All right”, he said, “calculate the error when the Taylor series approximation of a function is truncated after n terms. Do this and you will go free; fail and you will be shot”. Tamm slowly calculated the answer in the dust with his quivering finger. When he had finished the bandit cast his eye over the answer and waved him on his way.
“Ditz is a simple, light-weight distributed issue tracker designed to work with distributed version control systems like darcs and git. Ditz maintains an issue database directory on disk, with files written in a line-based and human-editable format. This directory is kept under version control, alongside project code. Changes in issue state is handled by version control like code change: included as part of a commit, merged with changes from other developers, conflict-resolved in the standard manner, etc.”—Ditz. Beautiful! Ditz, where have you been all my life?
“wtop is like “top” for your webserver. How many searches or signups are happening per second? What is the response time histogram for your static files? wtop shows you at a glance.”—wtop—even better than apachetop
