I set out to redesign my blog and throw in my consulting services in there. I decided to try a few techniques that I learned over the past couple of months, to get some practice. 90% of my work consists in experimenting, so that my customers would later benefit from the results.
Why Objects Over Arrays?
January 26th, 2017
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 […]

December 12th, 2016
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). It’s also an opportunity to remind them to be respectful and make sure […]

He makes some very valid points, but I’d like to add my own experience as an organizer, so that when you submit, you have multiple perspectives. Here are my replies to some of the points made.

MySQL Duplicate Entry, But Not Really
August 25th, 2016
I chased an interesting bug today. MySQL was complaining about “Integrity constraint violation: 1062 Duplicate entry”. I had all the necessary safeguards in my code to prevent duplicates in tha column. I gave up on logic and simply dumped the contents of the problematic column for every record. I found that there was a record with […]
File Permissions for Web Servers
June 21st, 2016
Many of you have asked me to write an article about Unix file permissions for web servers. This will serve to combat all those recommendations that are floating around, such as chmod -R 777, which I like to call the “hacker’s jackpot.” Basics of File Permissions The first concept to understand is the three roles. The user has the […]
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 […]
