Last weekend I went by Sidewalk Toronto's "experimental workspace" at 307 Lake Shore Blvd East. It is open to the public every Sunday from 11am to 5pm if you'd like to drop in.
This week they had their #BuildingRaincoat on display, which is an adjustable awning system designed to protect public sidewalks, mitigate the impacts of adverse weather, and improve outdoor comfort.
Also installed were a number of the paving systems that they are currently piloting. They're working with over 20 different vendors to try and create the "holy grail" of street paving.
They define that as a system capable of the following four key features: modularity, heating, lighting, and permeability. Here's an example of what one of them looked like (it was snowing at the time and, yes, Doc Martens):
With modularity, the goal is to make it possible for a single person to be able to pull up and replace one of the hexagonal slabs. This would dramatically change how we repair and patch our roads. Supposedly, they're also more resistant to cracks, which means fewer potholes.
The key benefit of a heated paving system is an obvious one. When needed, their test system automatically heats the slabs to 2-4 degrees celsius in order to melt any snow and/or ice. That's as warm as you need apparently.
They have two heating systems running at 307. The first is hydronic (fluid in pipes just below the pavement) and the second is conductive heating (thin conductive film in or under the pavement).
I'm sure many of you will be questioning the environmental and carbon impact of a heated public realm. And that is certainly a good question. But the status quo in this city involves about 131,000 tons of road salts per year. That's a problem.
The lighting feature is pretty neat because there are a variety of different use cases beyond just demarcating space. One example that Sidewalk gives is that it could be used in a bike lane to tell you how fast you need to ride in order to hit all green lights.
Finally, permeability matters because it minimizes runoff and allows water to be absorbed in situ. The tradeoff is that it makes the slabs structurally weaker. So that is still being worked on.
I am thrilled to see this sort of urban innovation taking place right here in the city. If you haven't already, I recommend checking out 307.
I have been using Google Translate a lot on this trip. Few people here in Rio de Janeiro speak English.
It is an incredible app that also works without cell service. You just download whatever language(s) you need to your phone.
There’s a conversation feature that allows you to go back and forth with someone in real time (almost).
There’s a camera feature that is invaluable for translating restaurant menus.
And there are a number of smaller features that I have also found really useful.
For example, if you rotate your phone into landscape mode, it will show you your translation in big text like a flash card.
It looks like this (trust me it is useful):
I also just learned that, since November 2016, the Translate app has been using a neural machine translation system developed by Google.
It is capable of understanding and translating complete sentences, and that has reduced translation errors by about 60% compared to the previous system.
Rather than translate word-by-word or phrase-by-phrase, Google’s NMT network encodes the “semantics of sentences.”

This is an interesting piece by Bloomberg summarizing the current state of autonomous vehicles and in particular the (supposed) dominance of Waymo (Alphabet’s self-driving vehicle arm). Many believe they will be the first real entrant into the market.
The company is currently running an “Early Rider” program in 25 cities. But its Phoenix trials are the furthest along, which isn’t at all surprising given the city’s car orientation and suburban fabric. Already Waymo has started offering passenger rides without a backup driver in the car.
Overall, the company has come forward with four main business priorities:
Ride hailing
Trucking
Personal vehicles
Public transit
But I still think that we’ll see a blurring of these priorities, if not outright cannibalization, as the cost per mile plummets. I mean, why own a personal vehicle if it is flat out easier and cheaper to just hail a robotaxi?
Here is an excerpt from the article talking about pricing:
Tasha Keeney, an analyst at ARK Invest, says that Waymo could choose to offer an autonomous ride-hailing service today at around 70 cents a mile—a quarter of the cost for Uber passengers in San Francisco. Over time, she says, robotaxis should get even cheaper—down to 35 cents a mile by 2020, especially if Waymo’s technology proves sturdy enough to need few human safety monitors overseeing the autonomous vehicles remotely. “You could see software-like margins,” Keeney says.
I can’t wait to be driven around for cents on the dollar. Click here to read the full article.
