Robertson screw patent bound with Robertson screws

When Canadian inventor Peter Robertson filed his 1909 Canadian patent for the now ubiquitous Robertson screw (patent 116463), he bound the patent application using his new screws. You can see them in the scans in the Canadian Intellectual Property Office’s database:

That’s dedication to a new invention.

Robertson was also granted a patent by the US patent office, but their scans are cleaner and don’t show the binding.

In 2013, Mayor Bloomberg asked designers to reimagine the city’s decrepit pay phones as internet-flinging, ad-spitting future machines. The winners were simply design concepts, never truly destined for reality. Now, the city is moving forward with the plan to retrofit its pay phones, after all.

On managing emotions vis a vis Canada’s Anti-spam Legislation

“Take a few minutes to bang your desk, raise your fists in the air, shout out some curse words, and any other action that you should probably do with your office door closed,” the guide states. “You don’t want to be harboring this rage going forward since you want to be focused on what you have to do, not being mad that you have to do it.”

First teach kids to be creative

The US copyright industry is apparently drafting elementary school curriculum to teach kids that copying is wrong. But, as Jane Park points out,

This message is way too simple. In this digital age, the most important thing we should be teaching kids is to be creative and take full advantage of all the web has to offer. Copyright, asking permission, open licensing, and all the other legal nuances, should be seen as secondary (and even complementary) to this purpose. We should be starting with the things kids can do versus what they can’t do.

Feel safe knowing websites only store hashes of your passwords? You’re not.

As Ars Technica writes, even if you use complex passwords and a hacked website only stores password hashes (not actual passwords), passwords are terrifyingly easy to figure out from hashes. As this article says, “with the hashes exposed, users should presume their passwords are already known to the attackers.”

To protect yourself, you need to use third party authentication like openid and two-factor authentication whenever they are available, as well as a password manager to generate and keep track of very long random passwords.

Otherwise, it looks like you should assume your password will get hacked.

The Sharing Economy

The Technology Quarterly section of last week’s issue of the Economist carried two articles on what they call “the sharing economy”, the category of electronic commerce that’s more peer-to-peer than B2B or B2C. Sites like let people rent out places to stay — whether it is a spare sofa or a full house. Sites like let people rent out their cars. and other sites let people rent out almost anything else they own.

The rise of the sharing economy is their cover story and provides an overview of these sites.

All eyes on the sharing economy is a longer article that goes more into the challenges the “sharing economy” faces, including regulatory hurdles.

I don’t know what the regulatory landscape looks like for all of these in Canada. It looks like airbnb is available in Canada (you can rent a room in Ottawa for $40/night or an apartment in Hintonburg for $71), but they likely make use of whatever legal structure has developed around Bed & Breakfasts. Car lending/renting may be more complicated in Canada, because the car rental services don’t appear to be available here yet.

It feels a bit like crowdfunding, which has been slow to develop in Canada partly because of (real or perceived) regulatory obstacles, but is a truly disruptive

What do you think? Is peer-to-peer lending potentially disruptive to more traditional rental markets? Will it develop into an important segment of the economy? Can existing regulatory frameworks already accommodate peer-to-peer renting in Canada?

Moving my blog to WordPress

I’m tired of moving my blog around. In a way, I don’t want to move it at all, and just shut it down, because really — why am I still doing this? But the platform where I’ve had my blog for a few years over at Posterous is shutting down, annoyingly, and the fact is that it’s easy enough to migrate the archive to WordPress, where it will probably be fairly stable for a long time to come. So that’s what I’m doing. More to follow one day when I dive ironically into narcissistic waters and write about why I’m feeling disillusioned by social tech in general. Or maybe that’s enough said about it.
