After an excellent weekend in Toronto visiting family and Tristan, I am back in Ottawa – reheating my apartment from its emission-reducing occupant absence chill. This is one of those calculations that is so difficult, when it comes to minimizing one’s carbon footprint: does it take less power to let your flat cool for three days and then heat it up again, or just to maintain the temperature across that span of time. I haven’t done the thermodynamic calculations, but my intuition suggests that cooling and re-heating is the better option.
Time spent enjoying the culinary skills of some of my cousins has encouraged me to buy some unfamiliar ingredients and see what havoc I can wreak before becoming competent in their use. The activity may help to offset the ever-diminishing prospects for cycling in this darkening city.

How well insulated is the apartment?
Diminishing prospects for cycling? Nah, get your lights out, your wool socks, your visibility vest, your studded tires and get into the winter adventure.

I think he is injured enough as it is. The last thing he needs is added danger from darkness and slick roads.
Public Invited to Try Their Luck Against Old Cipher Tech
By ScuttleMonkey on squeamish-ossifrage
Stony Stevenson writes to tell us that in celebration of the opening of the National Museum of Computing, members of the public are being challenged to take on a rebuilt version of Colossus, the world’s first programmable digital computer. The Cipher Challenge will take two groups of amateur code breakers and pit them against one of the original Lorenz cipher machine used by the German High Command during World War II. “The encrypted teleprinter message will be transmitted by radio from colleagues in Paderborn, Germany, and intercepted at Bletchley Park by the two code-breaking groups, one using modern PCs and the other using the newly rebuilt Colossus Mark II.”
