I saw a tweet earlier today “there seems to be this obsession with turning everything into an object”. Here’s a detailed response as to why using objects instead of arrays is a good idea, in my opinion. The Problem I once took over a project written in ActionScript 3. It was a fairly simple project. Five mini-games […]

Do you want to increase the efficiency of your remote communications by a factor of ten? Keep reading then. Respond immediately. If you have all the necessary information to respond to an e-mail, do it now. You already spent time reading the e-mail.

Conference Organization: Speaker Agreement

November 22nd, 2016

At ConFoo, we use a speaker agreement to ensure that accepted speakers take their commitment seriously and understand the impact of a cancellation. We used to lose thousands of dollars due to speakers cancelling after we already purchased their flight (as a non-profit, that hurts).

October 13th, 2016

I posted this tweet recently and got many replies. Since I was answering the exact same few questions dozens of times, I’d like to summarize everything here.

We are all biased

April 22nd, 2016

If you think that you are special and not biased, you’re not. We are all biased in some way. Before we talk about bias, let’s talk about inference and prejudice. Why does prejudice exist? When we are children, everything is new. We don’t have the experience to decide whether something is good or bad, so we don’t […]

Experience With Immigration Fraud

April 13th, 2016

As you may know, I organize a conference that gets many international speakers and attendees. Although many of them have no issue travelling to Canada, some require a travel visa, which means that the Canadian embassy in their country will grant them permission for a temporary stay.
