Canada must become a global superpower
The silver lining to the US starting a trade war with Canada and regularly threatening annexation is that it has forced this country out of complacency. Indeed, I'm hard pressed to remember a time, at least in my lifetime, when patriotism and nationalism has united so much of Canada. According to a recent survey by Angus Reid, the percentage of Canadians expressing a "deep emotional attachment" to the country jumped from 49% in December 2024 to 59% in February 2025. And as further evidence of...

The bank robbery capital of the world
Between 1985 and 1995, Los Angeles' retail bank branches were robbed some 17,106 times. In 1992, which was the the city's worst year for robberies, the number was 2,641. This roughly translated into about one bank robbery every 45 minutes of each banking day. All of this, according to this CrimeReads piece by Peter Houlahan, gave Los Angeles the dubious title of "The Bank Robbery Capital of the World" during this time period. So what caused this? Well according to Peter it was facil...
The story behind those pixelated video game mosaics in Paris
If you've ever been to Paris, you've probably noticed the small pixelated art pieces that are scattered all around the city on buildings and various other hard surfaces. Or maybe you haven't seen or noticed them in Paris, but you've seen similarly pixelated mosaics in one of the other 79 cities around the world where they can be found. Or maybe you have no idea what I'm talking about right now. Huh? Here's an example from Bolivia (click here if you can't see...

I installed and setup Health Canada's COVID Alert app this morning.
It's really simple to do that. You don't enter any personal information. You just select which province you're in, agree to let it use your Bluetooth, and give it permission to share the random codes that you collect with its servers (more on this below). The app is then active and working. But to be clear, it doesn't collect your location (it doesn't use GPS or location services). It doesn't collect the places or times that you are next to someone who also has the COVID Alert app. And it doesn't know if you're with someone who was previously diagnosed with COVID-19.
Built on top of the private exposure framework that was collectively developed by Apple and Google, the app works by using Bluetooth to exchange "random codes" between nearby phones that have the app. These are anonymous and random codes that are used to track which phones have been next to which phones for any meaningful period of time. The app also uses Bluetooth signal strength to estimate proximity. So it knows how long your phone has been proximate to someone else's (with the app) and how close they got to each other.
That's pretty much all that happens with the app unless you test positive for COVID-19. At that point, you will be given a one-time key along with your diagnosis. The onus is then on you to anonymously self-report on the app. Once you do that, anyone who was exposed -- i.e. next to your phone in the last 14 days -- will receive an alert on their phone via the app. And since the app doesn't know any names or who anybody is, it's of course all completely anonymous.
It's great to see all of this coming together. The private sector worked to build the underlying framework and now you have government building on top of it to deliver public health tools. I know that some or many of you will be concerned about privacy, but that appears to have been very well thought out. If you haven't already downloaded the app, I would encourage you to check it out. It's available for iOS and Android and can be downloaded over here.
