It looks like my bike computer had an ongoing GPS tracking glitch this morning. Hopefully it's a one-off and won't repeat on further rides (the unit is old, so). The result is amusing, at least to me.

(Neither the start nor the end point of the ride are correct and in fact relatively little of the plausible sections of the trace are actually completely accurate. This is way, way more off than tall buildings normally do, even in downtown Toronto.)

I want to get back into taking photos, so on yesterday's walk I decided to just take some with my (old) phone as I walked through Fairbank Park in Toronto right around sunset, when the light was great.

The disused/unused greenhouse in these pictures has been fenced off from people ever since it was built, many years ago, when it replaced some run-down bocce courts. No, I don't know what the city is up to with it.

(Did I go overboard with alt text? Maybe.)

My profile picture is cropped from a photograph of my old commuter bike. Ironically I no longer use anything in the photo; the frame developed a crack in 2016, I switched panniers, lights, and helmet, and sadly my old Ergon grips were lost with my stolen 'new' commuter last (2025) summer. I still use Ergon grips and that type of mirror, though.

(This was sort of a grab photo taken as part of one of my Project 365s.)

For no particular reason, here's my greebled up commuter bike in some of its natural habitats, first outside just before I left on this morning's commute and then in the office (in a not exactly scenic setup, but that's life). Enterprising people can look through the stuff on the shelves behind the bike in the second picture to find amusing computer things.

On my way through Highland Creek Park, I stopped briefly for other reasons and was of course prompted by thoughts of @derekvanvliet to take a photo of my bike.

During today's ride I stopped to take a picture of my weekend fun bike, inspired by @derekvanvliet (but nowhere as good, and also I don't ride every day). This is at the mouth of Highland Creek, at one end of the bridge where it meets the lake.

I think it may be time to retire these bike gloves, which I already use only for commuting. I wear gloves in hot summer weather because otherwise my palms get sweaty enough to start slipping on my handlebar grips. (These two pictures look different because I took them at different times for reasons, and also thanks automatic white balance.)

Current status: making another badly designed, probably over-dense Grafana dashboard, because I do want this information. Grafana is a box of sharp tools; using them to create aesthetic results is up to you.

You may think I'm exaggerating. Here:

A quiz (primarily for sysadmins/infosec/etc people): you've a hypothetical normal, ordinary person and you've received an email with a PDF invoice attached (so it says). You click on the invoice in your mail program and it shows you this. What are you seeing and how alarmed should you be?
