"Back during World War II, the RAF lost a lot of planes to German anti-aircraft fire. So they decided to armor them up. But where to put the armor? The obvious answer was to look at planes that returned from missions, count up all the bullet holes in various places, and then put extra armor in the areas that attracted the most fire.

"Obvious but wrong. As Hungarian-born mathematician Abraham Wald explained at the time, if a plane makes it back safely even though it has, say, a bunch of bullet holes in its wings, it means that bullet holes in the wings aren't very dangerous. What you really want to do is armor up the areas that, on average, don't have any bullet holes. Why? Because planes with bullet holes in those places never made it back. That's why you don't see any bullet holes there on the ones that do return."  (From http://www.motherjones.com/kevin-drum/2010/09/counterintuitive-world)

When considering software practice and process I wonder if we make the same mistake, looking to armor the area with the most bullet holes.  Every time you have to maintain some buggy annoying and difficult piece of software, you are patching up one of the planes that got home, that made it through.  No one maintains the software that never made it through battle.  The projects that flew on until they ran out of fuel, and due to navigator error never turned around to head home to base.  There's lots of failure modes.  Most of them aren't contingent on the quality of the software engineering.

This quote seems terribly wrong: "No one maintains the software that never made it through battle."  Ever seen this piece of software called Internet Explorer???

Yeah, this time-lapse video LOOKS awesome and cool, but I'm pretty sure this is how the end of humanity via grey goo gets its start.

Beautiful shot.
 
Reflecting Awareness

Chicago, IL

That's right, I was back in Chicago for a day trip this past weekend. Ate at some of the places we missed dearly, and stocked up on supplies. We made one last stop at the Museum Campus, where I took this shot.

My wife just reminded me that it has been a year since we moved to Wisconsin. While in some ways I miss living in a big city, I have come to enjoy & appreciate my new surroundings.

Get ready for a massive hangover, more than a dozen new breweries are coming to Chicago.
From food-inspired beer by a former Goose Island brewer to an in-house birreria at Eataly, more than 14 new breweries are opening in Chicago this fall and winter.

If this place was a business, it would have been gone years ago. Unless you are dropping your mail off at the mail slot in the building, go elsewhere if possible. Two specific incidents to report. While waiting outside, I witnessed them lock the main entrance a full 15 minutes prior to the stated closing time. Customers stood outside waiting for someone to exit the post office in order to "sneak in" even though it should have just remained open until the official closing time. Another incident had to do with a passport renewal. The employee in question simply refused to accept an expired passport as a valid form of identification, which clearly is acceptable based on the Department of State. As a result, we had to go to a different post office (on Ashland) to submit the passport form, where it was accepted without any problems.

Have been bringing our dogs here for 8 years and have never had an issue. The owner is one of the nicest people on earth, and so is everyone employed here. Could not recommend a business more highly.
