Making software that helps people be healthier. Looking forward to getting back to riding my bike stupid long distances once I finish treatment for cancer this year.🤞Based in Toronto. https://markallen.io

Perfect time for you to subscribe to my new API service that provides early access to my oncology test results before they go public. Why should Big Pharma be the only ones that make money off my cancer? (Obviously a joke, Kalshi & Polymarket should be illegal.) futurism.com/health-medic...

Kalshi Defends Plan to Bet on Lives of Cancer Patients

Users on Kalshi will even allow users to bet on whether drug trials for potentially lifesaving drug trials will succeed.

A story of cause and effect: Last November, Ontario banned cities from using speed safety cameras to issue tickets. Reckless speeding immediately surged in Toronto, Ottawa, Guelph, and cities throughout the province. A 🧵 about my latest in Bloomberg (gift link)

What Happens When Speed Cameras Get Shut Off

In 2025, Ontario banned automated traffic enforcement. Now the number of drivers exceeding the speed limit has surged, according to traffic data.

Civic Holiday is my favourite Canadian holiday because it’s true meaning is that someone realized you can just make a three day weekend when the weather is nice.

It's probably good that there's only one season of The Prisoner, because I'm halfway through and seriously reconsidering my anti-cape stance. These are dope, maybe I should get one for the autumn.

A weird side effect of one of my chemo drugs is that when I make a chattering motion with my teeth or tap my head with my hand, it sounds and feels like I’m tapping a ripe watermelon. Kind of a hollow echo. It is very trippy and entertaining.

The Bluesky For You feed is magnitudes better than the one at the old place. I'm constantly impressed with the relevance of the posts it surfaces. Today I saw a post saying that a railpath trail in my neighbourhood that had been closed for several years was now open. So well targeted! 👏 foryou.club

A paradox of AI layoffs I struggle to understand: During the early-2020s hypergrowth era, I constantly had to cut high-impact projects because my product teams lacked resources. Now AI gives us more leverage, and companies are using it to cut costs instead of expanding ambition.

At the startup, we are seeing large productivity gains time after time in deployments of AI that are done thoughtfully. There are so many important things that aren't done because there simply aren't enough people to do them.

I think it’s cute that the Tour of Denmark has a “King of the Hills” leader instead of a “King of the Mountains.” Here’s the route profile for today’s Queen stage, where they go over the same two or three small hills several times.

Portland is the best basketball city in North America. The new owner is speed running the Donald Sterling playbook of malicious hostility towards the fan base.

"The arena is only a small piece of that bigger picture," Dewayne Hankins, the Trail Blazers' president of business operations, told the council. "Portland's current stagnant business climate, high income taxes, and divisive political environment make this a tough city to invest in. It makes it harder to sell tickets, secure corporate partnerships and ... recruit players."

At the risk of wading into the "main character of the day" drama: As someone who was not aware that playing the spelling bee is now apparently considered transphobic, this doesn't feel like the most helpful way to get people on your side.

Screenshot of a Ken Jennings post where he talks about playing the NY Times spelling bee with his wife with a quote reply and a reply to the quote.

Quote post text: "I wish people who care about trans people could understand that playing nyt games is still an insult to trans people"

Reply to the quote post text: "well I guess we just found out he absolutely doesn't care and in fact thinks it's all a joke and we should lighten up because the nyt is an institution more important than our pain"

I truly don't understand otherwise seemingly intelligent people who share direct AI output like "Here's what ChatGPT said about [topic]:" Buddy, if I wanted to know what ChatGPT says, I can ask myself. You aren't adding anything here.

I’m going back to the US in a few weeks to visit family in Ohio, and I’m googling things like “can I drink the water?”, “which foods are unsafe to eat?”, and “will I have problems with border guards?” Great job America, you are now a developing country in the 1960s. www.nytimes.com/2026/07/29/c...

In Ohio, Toxic Wastewater Is Bubbling Up Out of the Ground

The state is a major importer of fracking wastewater, which gets pumped underground but doesn’t always stay there. The city of Marietta is fighting back.

All of my Duolingo lessons this week seem to be about salted cod. This is not a dish I have ever ordered, nor a topic I have discussed with anyone in France. Perhaps I’ve been missing out on a key part of French culture?

Trying to track down the source of Satre's "eyes of the least favoured" principle in his 1952 book The Communists and Peace, and the PDF I found online is missing the exact pages it appears on. Clearly this is a conspiracy to hide such powerful ideas from the public.

Screenshot of an open PDF of a scanned book. The pages jump from 179 to 182.

Canada's mini-Elon is mad that democracy led to the cancellation of Toronto's waterfront airport expansion, making it slightly less convenient to hop in his private jet to fuck off to his little Galt's Gulch fantasy world.

Screenshot from X, the world's foremost neo-nazi platform. Shopify CEO Tobi Lutke is responding to a tweet mocking a community planning input session featuring older adults (the meeting in question was not in Toronto).

Quoted tweet: 'Community input' just means obese old people never letting young people have anything.

Tobi's response:

Exactly what just happened in Toronto. 

Retired, Unemployed, Unemployable, and useful idiots are the only people who go to these town hall sessions.

Absolutely influenced by recency bias of the third week of the Tour, but this is my ranking for most enjoyable riders to root for this year: 1. Richard Carapaz 2. Baptiste Veistroffer 3. Tadej Pogačar 4. Torstein Træen 5. Tim Merlier 184. [Unnamed, problematic American who actually rode well]

Since LeBron isn't going to come home to Cleveland (the only acceptable outcome), I am going to very much enjoy the Philly fans turning on him in November when they realize this is a 41 year old guy trying to keep his body working well past the expiration date.

Watching Richard Carapaz attack in the mountains is such a delight. It feels like he's the purest embodiment of vintage climbers in the modern peloton, and impossible to root against.

Richard Carapaz climbs through cheering roadside crowds in the Alps on his way to winning Stage 18 of the 2026 Tour de France.
