#NoProjects/#BeyondProjects: A Developer Footnote

During the post-conference drinks I was chatting with a developer - Matt from New Zealand if my memory serves - and he came out with what some might think was a surprising comment. He said: “I’d never thought of a project like that before.”

Man, Woman, Dog: A Task from the Past

This article describes solutions for an exercise that was given to students by economics faculty who visited my computer science department 10 years ago. The task is relatively easy but somehow we couldn't manage it at that time. The program had to be written in C, which we didn't know well and was one of the reasons for the failure. Two weeks ago I decided to finish this problem so I sat in front of my PC and implemented two possible solutions for it in Java.

Email is older than the web, and it’s way past due for an improvement. We want to see JavaScript turned on in email packages. I feel that is inevitable, and it’d be nice to have a product that can immediately take advantage when that happens.

If you hear "perception is reality" you're probably being screwed

I was once told in a performance review that “perception is reality.” I was infuriated, and the words stuck in my mind as the most toxic thing a manager could say to an employee. Let me tell you what “perception is reality” means, and why you should plan on leaving your job the moment you hear it:

How well does sample range estimate range?

I’ve been doing some work with Focused Objective lately, and today the following question came up in our discussion. If you’re sampling from a uniform distribution, how many samples do you need before your sample range has an even chance of covering 90% of the population range?

Task-based web browsing: Grunt and the grunt-open plugin

So in the directory where this Gruntfile.js lives, I just have to type "grunt webhumor' in the command, and Grunt will open the appropriate sites. Not a huge timesaver, but kinda cool.

I’m a believer that engineers not only need to act in a professional and ethical way, but they have to have a sense of humor too. For that reason I have the tradition to tell my class (almost) every semester week a joke or fun story with an engineering background. I have been asked to share the fun story from this week, so here we go...

Presenting on Trunk-based Development at the Perforce MERGE Conference

This was a month ago at Perforce’s MERGE 2014 conference, but the videos are up now, so you can watch it too. Of many case studies that I have, I detailed one where a hedge-bet on the order of releases paid off. Not that the client knew they were hedge-betting at the outset, that’s just the reality of Trunk Based Development, Feature Toggles / build switches, and Branch by Abstraction.
