Conway’s Law

I ran across this a few weeks ago; now I’ve got some time to put some thoughts down: Conway’s Law…organizations which design systems (in the broad sense used here) are constrained to produce designs which are copies of the communication…

But I like the cookie…

One of Seth Godin’s recent blog posts (The Reality of Digital Content – lose the cookie, lose the fortune) has been reverberating in my mind over the past week. What happens when the people with great ideas start organizing for…

PodcampTO 2010

Another little conference this weekend; close to home, fortunately. It turned out to be a lot of same-old, same old though: The powers-that-be don’t want us to use social media, or if they do, they haven’t a clue how to…

My Olympics Contribution

Fortunately, we’re doing slopes in our MPM1D course and I knew I’d be away for Educon for a day so I continued the adaptation of a slope assignment from last year. Last year things were strictly 2D. First, they went…

Setting up Ning

School for us doesn’t start until September 14th but I’ve completed all my computer changes for the year (dual monitor, 1Tb hard drive & 500Gb network hard drive, N-router & card, new headphone-mic) and my nephew has gone back home…

Math Video Markup

As I mentioned in an earlier post, my students will often be required to submit Jing videos of their worked solutions to a variety of problems. Basically it’s the modern alternative to handing in paper copies of their homework but…
