Professional Update

2014-04-04

Last July, nearly a year ago, I left RIM/BlackBerry and joined a startup in Waterloo called TrustPoint as Engineer #1. That's a big change for me. BlackBerry was (and still is, in some way) a significant part of my world.

I'm now building a Certificate Authority for non-humans from the ground up. It's super challenging work, spanning a multitude of disciplines.

Since this blog rarely gets updated, I should mention that I'm on twitter @terrilldent.

Secure Login without HTTPS

2013-12-06

Still working on my secure login without HTTPs. My non-comprehensive list of desired qualities:

Progress is coming along nicely. The authentication and validation steps are working, which means I have a functioning system. Next I need to exercise it and make sure it works in practice.

Bitcoin Caution

2013-12-01

Hacker News is interesting because the community will periodically promote some anti-community ideas to the top. I was encouraged to see a cautionary bitcoin post in the top spot this morning.

Read the article, think for yourself, then read the comments.

Predictably the top comments attack technical details; in the process missing the message.

I'm strongly of the opinion that Bitcount will not end well. It has the bad qualities of gold, including a cost of mining. It has no central bank to help it, which some may celebrate now, but wish they had later. Unlike gold, which continues to be mined, there are a fixed number of eventual bitcoins. This is not good. Bitcoin is misunderstood by most holders. Holders don't use it as currency very often. And the list goes on.

Launch

2013-11-18

I've decided to relaunch my website. I wanted to create a space that had more room, and is easier to fit complex examples into. In that spirit I have abandoned columns and for now I'm writing static HTML.

The Projects page has been updated to show some of the things that I have been working on. There is a lot more in the works.

If you haven't heard, I recently left BlackBerry for a software startup. We work in the cryptography space. I look forward to sharing more about that soon.

Build

2013-11-10

My previous blog was custom written, and I learned a lot while building it. Armed with newly minted knowledge about secure systems, I plan to implement my new blog with some interesting security considerations. To avoid increasing my hosting costs, I endeavour to make something I can feel confident using without HTTPS. When it's done I will describe how I did it.
