We're meeting once a week and have decided to use this as a "demo project" to work through project issues as well as being a boost to coding skills. And of course, that means we're dealing with the dreaded "R" word. Requirements. Gotta do em'.
So we tried to hash out what the "overarching architecture"
should look like. Got lost in philosophical rabbit
trails. Wondered where intelligence/data/processing should happen.
And then, after poking about some of 37signals manifesto, I came up for air and wondered...do we REALLY need comprehensive BDUF requirements?
So we rethought a few things. Today's meeting looked like this:
Guiding design principles
- encapsulation
- loose coupling
- build for extensibility...but keep things reasonable
Ways to go forward (breaking analysis paralysis)
- What's the smallest useful bit I can impliment? (think: credit
card payoff - doing the small ones first/ Brooks observations on incremental development = small successes keeps
the morale flywheel going)
Requirements
- What is the minimal requirements set needed to get the minimal functionality going?
- Use "guiding design principles" where possible, use hard-and-fast
requirements where necessary. (of course, "necessary" is always up for
debate..) - Think "growing" software vs. "building"...so build in extensibility. Think "encapsulation/objects"...
- Maybe a useful thought would be "how much encapsulation is
reasonably necessary to re-use this module in another app?"...that
might help with removing unnecessary dependancy on other modules too...
AR's (action required)
(sorry...old Intel-ism. I've just always thought AI should be artificial intelligence..)
A:
- build a basic robot with 2 axis of motion. (maybe 3rd axis would be ultrasonic sensor?)
- Build a basic test-harness to move the robot through motion.
W:
- Begin experimenting with his USB cam and the motion sensing API
at http://www.codeproject.com/cs/media/Motion_Detection.asp (check out
his other articles for the image manipulation algo's used in the motion
sensing kit..)
Both A and W
- Remember that this is supposed to be FUN. If it starts being a CHORE and stops being FUN we need to re-eval... =^))
