Every time I charge my Apple Watch and put it into Night Stand mode, laying it sideways...I always think of that meme of applying for a dream job just to fix one bug ...
The display on the Apple Watch reads 1:06pm with today’s date: Tuesday 11 (November) The watch is laying sideways on my cork desk, and the display is in Landscape Mode - I can read the text without twisting my head! Same Apple Watch, except the display is now in *Portrait Mode* so now I have to twist my head to read the text correctly! Display reads 1:06pm, Airplane Mode. Battery charged to 59%

Currently reading: @sebastianraschka.com’s book on building an LLM from scratch!

Back to Appendix A for me to brush up on PyTorch!

I didn’t take Calculus in High School, so I’ll have some background learning to do there too.

Saw this newspaper open in the local coffee shop on the weekend, and it sparked an idea…

@bmann.ca how about a Wild Goose Chase (aka Treasure Hunt) around UBC during #ATmosphereConf …
An article in the Vancouver Sun from Saturday November 5th titled “Wild Goose Chase” outlines a story about how Canadian Geese are now heavily populated in urban areas and how they’ve seen a resurgence in numbers over the last few years

Easter Egg Alert!

Google Maps and Ford Bronco teamed up to map the TransAmerica Trail – all 5,900 miles of it.

When you visit the 4 Street View scenes link in the article...there's a person dressed in camouflage in frame in 2 of them!

For a while I’ve been using Cursor to help find Accessibility issues in frontend codebases.

It’s been great for identifying issues, and then remediating them too, for the most part.

Of course, no ARIA labels are better than bad ARIA labels, so it’s worth investing in learning about what works too.
Screenshot from Apple Notes titled “Finding Accessibility Issues”. Here's the prompt I used with Cursor to review a React codebase for Accessibility issues: Let's analyze this code base. There are likely to be a series of Accessibility Issues that arise from this code base, including keyboard traps, a lack of aria labels, poor use of semantic HTML etc. This codebase relies heavily on React and TypeScript and imports from libraries, so it may not be entirely possible to catch or fix all the issues. That's OK. Please highlight as many issues as you come across. Once you've collected the issues, write them to a markdown file, showing the filename, the line number, a reference to the WAG Success Criteria, and a brief description of the potential issue. We're targeting against WCAG 2.2 AA Success Criteria. Screenshot of Apple Notes titled “Finding Accessibility Issues” Once the markdown file is created with the list of issues, I used a 2nd prompt. Using this file (use the at tagging @filename.md) as a reference check list, let's go through each file one at a time, and make the necessary changes. Pause after each file change to let me review the changes.

Yeah books are cool, but have you ever bought a copy of a book signed by the person that invented the World Wide Web?! @timbl.bsky.social
The cover of “This is for everyone”, by Tim Berners-Lee. The blue cover, has a circle made up of dots coloured red, orange, yellow and blue. In the centre it says “Tim Berners-Lee, The Inventor of the World Wide Web” On the left page About the Author Sir Tim Berners-Lee invented the World Wide Web in 1989. CERN in Switzerland. Since then, through his work with the World Wide Web Consortium (W3C), the Open Data Institute (ODI), the World Wide Web Foundation, the development of the Solid protocol and now as CTO and cofounder of Inrupt, he has been a tireless advocate for shared standards, open web access for all and the empowerment of individuals on the web. A firm believer in the positive power of technology, he was named in Time magazine's list of the most important people of the twentieth century. He has been the recipient of several awards, including the Seoul Peace Prize and the Turing Prize, widely recog nized as the Nobel Prize for Computing. He was knighted in 2004 and later appointed to the Order of Merit by Her Majesty Queen Elizabeth II. On the right page “Signed by the author”, followed by the signature of Tim Berners-Lee, and the publishers name, Macmillan

WatchOS 26 and they still haven’t fixed this one simple rotation
Apple Watch on the charging screen. The watch is on its charger, laying on its side. The screen which displays the battery charging level hasn’t rotated, as the text is turned 90 degrees anti clockwise. Battery charge is 98%, airplane mode symbol is showing and the time is 12.16pm

A head scratcher: getKnownFollowers call has a limit of 30, and only returns 26 profiles.

I guess it's a limit, not an exact quantity?

I'm seeing similar behaviour when I loop over getKnownFollows in code.

I currently follow 642 profiles, but only 634 profiles are returned.

Fleet week in Vancouver!
On the left is HMCS Vancouver, on the right is HMCS Regina. Two Halifax class Frigates used for submarine hunting and long range patrols. Their photo shows the ships from the front, each with a Canada flag flying in the breeze. In the background is downtown Vancouver skyline A more side on view of HMCS Regina, and the pier in North Vancouver at Lonsdale Quay Front on of the ARM Benito Juárez, a Mexican frigate. In the background is the downtown Vancouver skyline A side profile from the port (left) side of the Juarez. In the background are the two Canadian frigates - HMCS Vancouver and HMCS Regina. The Juarez has long sweeping sharp edges, compared to the softer edges of the Canadian ships
