Back in September 2011, a group of McMaster business and engineering students started a project aimed to build a moon rover that would be run by the QNX operating system on a BlackBerry PlayBook - a Canadian initiative with Canadian technologies (QNX is 100% Canadian). Here is a link to the original article on CrackBerry.com from the beginning of the project: https://crackberry.com/forums-new-group-aims-put-blackberry-playbook-powered-rove..

Busy day yesterday! Got a lot done. Switching light source from one entity to another proved to be surprisingly quick and easy. I was done with my emitter attribute in no time.

Hi All, Just finished working on the more complete fix. More importantly, the fix that I completed on Tue 27th has been approved by the marketplace and should be available to everyone soooooooooooon, once the changes have propagated through the marketplace systems. Hopefully this should be around Monday but I’m still at the mercy of the marketplace, in the meant time you can try and force the update but I’ve not had any luck so far with t..

Got a bit more sleep last night - went to bed at 2am instead of 3-4. The lighting saw a lot of progress. I think all of the core functionality we need thus far is in. There will be tweaking of lighting levels etc, but in terms of what it can do - it’s pretty much all good for the time being, although I’ve accounted for the possibility that we may need to add more to this later and made sure the code is fairly flexible. This meant that l..

So you want to be a consultant. You probably think this will involve yourself talking and your client respectfully listening. Your client will put you in front of her team to present a PowerPoint deck outlining how Everything Will Be Different Now. You will then distribute copies of your Initiative Plan to each of her subordinates. Once you have given everyone their marching orders, they will do exactly what you outlined in orderly fash..

A separate monitor is handy for showing tests results continuously while working. The paintbrushes are strictly optional. What follows is a somewhat rambling introduction to continuous, test-driven development, focusing mainly on Python and influenced by Clojure tools and philosophy. At the end, a simple script is introduced to help facilitate continuous TDD in (almost) any language. For the last four years I have increasingly foll....

The agile community is full of people who say things like "communication must be as rich as possible,by which they mean, "in person, simultaneously in time, and proceeding from high level to detail." Not content with this message, our community members often go the extra mile to say things like "there's no point in expecting good communication to occur otherwise. [heavy sigh]"

How to Make Facebook Like Button on a Website Connect to a Facebook Page

I wanted a simple 'Like' button connected to my facebook fanpage. No stream, no faces, no counts, no nonsense. I couldn't find an easy and obvious way to do it. I spent more time than I would care to admit trying to figure this out and it turns out to be trivial. Go to Like Button developer tool. Set 'URL to Like' to your facebook page ( http://facebook.com/FacebookName ) Set 'Width' to '50' Uncheck 'Send Button' Choose 'Button Coun..

Just In Time Software Requirements: Introducing "Value Spikes"

I've been pondering further difficulties of being a product owner, both silently and aloud, so yesterday I was happily bowled over by a new idea on the topic from my new Thoughtworks colleague Jasper "Dutch" Steutel (@dutchdutchdutch for twitterphiles). He calls his discovery the "design spike," and we ended up talking together about a related concept, the "value spike." So what's this all about? Aside from being "Vampire Month" on the P..

I don't mean to go all "woo woo" on you, but you already have a personal online brand. Don't believe me? Bring up your favorite browser and type your name in quotation marks ("Firstname Lastname"), and do a quick search. Try it again with your middle initial added. Did something come up? THAT's it! It's your personal brand!

As you join your teammates in your sparkling new agile team room, and you all do your best to quickly "become agile," I guarantee that despite being surrounded by brightly colored index cards and sticky notes, you may sometimes feel...angry. Here you are, supposedly liberated to be "self managing," out from under the collective thumbs of your corporate hierarchy, and you realize that you are reminded briefly of the Lord of the Flies.

You might not expect to encounter the "delegation" concept in a blog post about agile software development. After all, agile is all about the "self governing team." But in the real world, if you are in a company which is transitioning to agile, and you are the project manager of a newly created agile team, you may well need to consider how to create a situation around your team that allows self-governance to emerge without making you comp..

Agile purists may be frightened to learn that in many enterprise environments, one of the first steps executive management may take towards agile adoption may be to establish an official agile SDLC process, and to post a diagram representing the process, along with its artifact templates, in some prominent place on the company web site. There will be 3-D box diagrams and arrows on it for sure, along with many links and appendices. The dia..

I got a tweet this morning about the new VersionOne "State of Agile Development Survey" in which the re-tweeter used hashtags like #shocking and #fail. Looking for a good laugh, I clicked on over to the survey, and realized I #liked the survey and I thought it was #interesting and #helpful to me. I didn't find anything that jumped out to me as a #failure in a particularly #horrifying way. Then for a moment I thought maybe I am not one of..

Sometimes your code needs to call a static method in a 3rd party library and unit testing suddenly becomes difficult, particularly when that static method requires context in order to work. Enter the insulating class (also known as a Facade). Create a new interface that declares a method with the same signature as the static method you want to delegate to Create a new Facade class that implements the interface Replace the calls to the ..

I’ve been doing a lot of work with timers and multiple entity spawning, as well as modifying entity attributes on the fly based on player input. It’s been very interesting - and possibly the most interesting part is that it hasn’t been that hard. Yet. That’s a very present “Yet”, just so you know. It will get harder. To get my head around what has to happen in-game I’ve been sketching and jotting things down on paper in the notebook I origi..

Over time, I've started noticing a trend: as humans we have a great aversion to pain. Okay, that doesn't really make me a master of the human mind, but it's still a starting point. Hearing this, an appropriate response would be suprise: how could it have possibly taken that long for me to come to that realization? I suppose the real issue isn't that people don't like discomfort, but that I'm starting to see the things that people are willin..
