CAPTCHA. reCAPTCHA.

Finally installed the very excellent reCAPTCHA plugin for WordPress. I like it when my posts get comments, I don’t like it when the comments are spam. So, if you look at the comment field on this blog, it’s got the reCAPTCHA interface hanging out, keeping us safe. Also, reCAPTCHA helps decode books. Awesome!

You should post a comment — try it out! 🙂

Velocity, or v = dx / dt

I was coworking at Stardust today, and we got to talking about Agile Development, and the concept of velocity.

Disclaimer: I hate buzzwords. But, these terms have specific meanings, and although it sometimes sounds cheesy, there really is something to this Agile movement.

Basically, velocity is an Agile concept that is a self-calibrating method for estimating how much work can be done in a unit of time.

The trick is that velocity doesn’t really measure the work done, it measures how much estimated time it takes to fill an actual week of working. The trick behind velocity is that you track (per task) the estimated time of completion, and the total amount of estimated work completed in a unit of time (usually a week). As long as the developers who are on the project are always the same ones handling estimates,  if they have a tendency to overestimate or underestimate, it will be canceled out after the first week or two. Make sense?

If you haven’t tried Agile development processes, I strongly recommend it. There’s a game that was created to help explain how Agile/XP works,  calld The XP Game. It’s a reasonably entertaining way to learn business stuff (better than a pointy haired lecture!), and doesn’t take long.
I’ve still got lots to learn about the finer aspects of applying Agile/XP, but I’m happy to talk with anyone about these ideas — I might learn something new 🙂

Gnip comes a-gnocking

I wanted to cover a nifty-looking service that’s just launched — Gnip.

It’s a simple premise: instead of asking every social networking service what’s going on, Gnip will tell you what’s up (they’ll even POST it to your website). They’re going to be — Atlas-style — lifting a huge weight off of social networking providers. I hope they do well.

Of course, in the interests of disclosure, I know Eric.
