Today FastTrackTO is officially launching and releasing our 10 point plan to modernize the Toronto Streetcar network. An iconic symbol of the city that could be fantastic with some achievable, common sense and low cost changes. The plan if implemented would transform the city.

I still remember my Great HDD Corruption of July 18th, 1994.
My oldest file dates, restored from 1.44MB floppy backups, have a date of 07/18/1994.
It was a 210 MB HDD, and a big computer crash caused SMARTDRV.EXE corruption that must've sprayed random data on my FAT.

40 years ago on a Commodore 64, I typed this command to save my first BASIC program to floppy disk.
SAVE "COMIC PAGES", 8
40 years - February 1986 - February 2026
Happy 40th birthday to the start of my software development career. Thanks mom & dad for the C64!

A steampunk way of describing GPUs is calling them "math cannons".
That's what Charles Babbage would call them in the 19th century -- whether it's over a teraflop of FP64 or over a petaflop of FP4 -- of either an NVIDIA RTX 5090 or Radeon RX 9070 XT.

It seems like a good time to repeat how thankful I am that the entire Canadian federal election process has a campaign period that’s at least 36 days and no more than 50 days.
That’s it.
With strict spending limits.
And every single time, that ends up seeming long and expensive to me.

I am impressed at the improved bikability of my seasonal home at Lake Chapala, Mexico (remote working). They recently built some great concrete protected bike lanes. Though I avoid high noon for obvious temperature reasons.

Feb 22, 1893: the Toronto Telegram reports on the two oldest surviving Canadian steam locomotives passing through West Toronto Junction. The engines—the "Samson" (1838) and the "Albion" (circa-1840), along with a tender and passenger coach—were en-route to Chicago. 1/3

2024 is the 30th anniversary of the Netscape web browser in 1994, long before Chrome & Internet Explorer.
Netscape could stream text & images in real time over 0.0144 Mbps dial-up modem.
Far faster than NCSA Mosaic that downloaded ALL text & images before displaying websites.
