This is part of an on-going series of “Blockchain according to jono” in which I try to explain blockchains to both a non-technical and technical audience. This post describes some of the basic things blockchain enables.
This is a continuation of Debeakered.
As part of my work at Sojourn Labs (more about this at a later time), I’ve recently been working with creating a secure private cloud based on CoreOS, Docker (basically, a lightweight virtualization system), and some decade-old (or older) hardware. Different applications within the cloud need to communicate with each other securely. For example, our wiki needs to communicate with our database server. To link two Docker containers on the same machine together, one need only instruct Docker to create a link between the two. Things get more interesting when the communicating containers reside on different machines.
In yesterday’s New York Times, there was an article about people getting angry over changes to Instagram’s privacy policies under Facebook rule. Rebecca Lieb of the Altimeter Group was quoted as saying
There are always Facebook users who say ‘This is the last straw,’ [but] there’s not a lot of portability. Where would you go?”
Writing a slick iPhone app is exciting. Building a communication tool that changes how people communicate is stimulating. Hacking1 into a bank’s security system to pull of a heist is the stuff of Hollywood. “Liberating” information from classified sources can lead one to be hailed a hero. Writing test cases for code is sexy. Wait… what?

Star light, star bright,
The first start I see tonight;
I wish I may, I wish I might…
Hey, that’s no star…
It’s a satellite!
Looking up into space as a kid was so much simpler. Camping in the woods is no escape.
Maybe she was right; I am obsessed with Rob — I was clicking refresh over and over for this one. But he’s gone, now: Rob Ford removed from office. As you might have noticed, now that the Globe and Mail has gone behind a paywall, I’m reading the Toronto Star for my local news.
How do you suggest to a student that you think he/she should drop a course? Let’s ask the Internet!
“How to tell someone” … autocomplete suggestions “you love them” or “you have herpes”.
Nope. These questions might be related — just not to my question.
“How to tell someone you think” … “they have borderline personality disorder”.
“how to tell someone you think they should drop” … “a class”. Bingo.
No relevant results. Why did you suggest that autocompletion?
Open letter to the Internet:
I thought you knew everything. When I was three, I used to think my parents knew everything, too. Now, I see that I am wrong again. How many times can one face disillusionment in life?
Edit: Internet’s response:

Dear user 7138620,

I’ve been following the current hearing about Mayor Ford and his alleged run-in with the Municipal Conflict of Interest Act (MCIA). Over lunch, I explained to Daniel Levy, one of Steve’s new students, the gist of what is happening. Daniel, hailing most recently from Winnipeg1, rightly wondered if the Mayor’s oafishness is due to cherry-picked quotes from the media. Continue reading “The War on Toronto”
- Daniel had his bike stolen the week after he arrived and now he gets to hear about our mayor. Welcome to Toronto! [↩]
After a hard disk failure that finally rendered MacBook Air #2 unable to boot (or even formatted so as to boot), I’ve set up its replacement MacBook Air, MrRoboto, to be as “automatic” as possible. Things should “just work”. This particular blog post is about automatic tunnelling. If you don’t know what
ssh or a local/remote tunnel is, this post is not for you. It’s also aimed at Mac users.
