Amazon is listing Retrospect 6.0 for the Mac as discontinued by the manufacturer, though they still have some in stock. Hmm, looks like maybe they just don’t have the new 6.1 version yet, because I do see that on EMC’s web site. Furthermore, I notice that “Customers with Retrospect 6.0 can use their existing license code and download Retrospect 6.1 for free from our Updates section.” No need to push the panic button just yet.

I’m trying to devise a regular expression that will find all or most img tags that don’t have alt attributes. <img[^>]*/> will find all the img elements (or at least most of them). And I can easily find those that do contain an alt attribute. However, I’m stumped when it comes to finding those that do not contain the substring alt. Any ideas?

In all the brouhaha over JetBlue stranding passengers on airplanes for hours last Wednesday, one thing I haven’t seen explained until now is why this specifically happened to JetBlue. Usually when we hear a story like this, it’s at a major hub airport like Detroit that’s primarily served by one airline. JFK is a hub for JetBlue, but unlike Detroit or Atlanta, JetBlue is hardly the only airline with a lot of planes there. What did JetBlue do wrong that other airlines at JFK didn’t? The New York Times seems to have figured that out. In brief:

• Other airlines canceled more flights sooner due to the weather.
• Communications within the company broke down. Pilots and flight attendants were not able to get assignments.
• The reservation system was overloaded so passengers could not get through to humans.

A lot of this is blamed on both the rapid growth and low cost structure of JetBlue. They hadn’t built enough slack into their systems to handle an event like this.

How many times have I been at the airport waiting for a delayed plane? I’ve lost count. Dozens of times, and I’m not all that frequent a flier. Sometimes I’ve waited almost an entire day. How many times have the airlines told me the flight is delayed before I left my house? Exactly once in over thirty years of flying, and that was almost twenty years ago. Something needs to be done.

Sleepycat asks some interesting questions about a non-standard persistence API they are developing. By the way, non-standard is good. Ideas like this should be tried out in open source products first before baking them into standards. I applaud Sleepycat for taking this route instead of rushing into the JCP. Indeed standardizing in advance of implementation experience explains a lot of the problems in JEE that APIs like this one are designed to replace. Anyway, on to the questions:
