There was a time when everyone in Winnipeg shopped at "The Big Store".
With a staff of 8,000, it covered 21 acres.
On a busy day, 10% of Winnipegers shopped there and 50 cents of every shopping dollar was spent there.
This is the story of Eaton's Winnipeg store.

ALT This vintage photo shows a nighttime city street, likely mid-20th century. A large brick building glows with red neon outlines and a prominent "EATONS" sign, indicating Eaton's department store. Festive lights form swirls, stars, and flowers across the facade and street, evoking holiday cheer. To the left is a "Woolworth" store with blue signage and window displays. The wet street reflects lights, with few pedestrians and a Christmas tree visible. Background includes taller buildings with "EATONS" and "BMO" signs. The image has a warm, grainy nostalgic feel, watermarked "GRP" in the corner.

On this day in 1917, the Mont-Blanc exploded in Halifax Harbour, releasing a 2.9 kiloton explosion.
The largest human-made explosion in history to that point, it killed nearly 2,000 people and injured 9,000.
Let's learn about this dark day.

Labour Day has been a statutory holiday in Canada since 1894. It originated in the first workers’ rallies of the Victorian era. Historically, workers marked the day with parades, speeches, games, amateur competitions and picnics.

You really, really should not be relying on AI detectors for classroom use.
This new paper shows that not only are they very easy to defeat by just prompting a couple of times, but they have insane false-positive rates against non-native English speakers. arxiv.org/abs/2304.02819

👩🏫 Let's break the myth that formality of assessment determines the importance of assessments in the classroom. Informal conversation can be as valid as a formal test. 📋#LeadInclusion #edchat #edtech #spedchat #sblchat

#DDay 🍁79 years ago today, 14,000 Canads and 7,000 Brits landed on Juno Beach. From 7:30-8:00 am, the first Canadians launched attacks along a 8km stretch of beach. Despite the heavily entrenched enemy, by evening, a Canadian bridgehead was established on the coast of Normandy.

This means, by the way, that AI can conduct scientific fraud on command. Just tell GPT to “fix” a dataset by making & justifying changes to make a regression work better. It will give a “better” CSV. Not showing prompts, but it is trivial & another threat to academic integrity.

For many teachers, AI detection offers a weapon to deter a 21st-century form of cheating. Yet even Turnitin's executives say that treating AI as the enemy of education makes about as much sense as trying to ban calculators. @geoffreyfowler @washingtonpost

Just finished recording a virtual tour of the Assiniboia Indian Residential School site (in River Heights, Winnipeg) for my IRS History class, to pair with the book we’re reading for this week on the school and commemoration practices.

Humans don't seek opposing viewpoints enough.
This is why AI is so useful.
We can easily ask for contradictory ideas in a safe environment where nobody is actually going to get mad.
Give your content to a bot. Ask it to challenge you and see what happens.

We have a new paper on how instructors can use ChatGPT and Bing to apply complex pedagogy to their classes, while making their lives easier, too. There are lots of prompts to try out.
