Jeremy writes about a plane running out of gas and landing at Tully Road. I witnessed this event! Remarkable. We coders take for granted that you can get stale on your knowledge and just Google it back later. Pilots need to always be in top form.

Eric Meyer (who else?) has the answer: The property line-height can accept unitless number values. You can also give line-height united values, though generally you shouldn’t. But unitless numbers are just fine for this property. So what’s the difference? When you define a united value, like 1em, you’re setting things up to pass along the computed result to any descendants. … This is why it’s always strongly recommended that you use unitless numbers if you’re going to set a line-height on something like the html or body elements, or indeed on any element that is going to have descendant elements.

Says Michael: If you haven’t heard of Ajax yet, you will and I don’t mean the bathroom cleaner. Ajax is a new style of programming which makes it possible to have the advantages of web services with a responsive interface like traditional software. In the past web based tools have been handy because they load quickly, are free and are always up to date. But web interfaces are limited and operation can be slow as the slightest changes forces the entire screen to redraw. Ajax makes it possible to have full featured software like the applications you are familiar with on your desktop, but that load over the internet. Early examples are Gmail and Google Maps, but they have just scratched the surface of what is possible. A new venture I’ve been working on for awhile will change what people think is possible with Ajax.

Says Charles: Ever wonder how virtualization works and how (and where) it can be applied today and in the future? What role could virtualization play in the future of Windows, for example? How ans where is it used today? We recently met with some of the Microsoft virtualization people to find some answers to these questions and learn a whole lot about virtualization, hypervisor, and the future of this super cool technology, generally.

Retired Virginia banker John Q. Brrreeeport came forward today as the second accidental shooting victim involving Vice President Dick Cheney. In a Tuesday morning press conference Breeeport said … (ok, have I successfully grabbed your attention? Good.)

News.com reports today that Oracle said Sleepycat’s open-source Berkeley DB database will complement Oracle’s existing line of closed-source databases for embedding within applications. The products differ from Oracle’s flagship enterprise database software used for general business systems.

Also, the purchase of Sleepycat, which has been rumored for weeks, gives Oracle another open-source product to accompany its proprietary database offerings. At an investor conference last week, Oracle CEO Larry Ellison reiterated the company’s strategy to generate revenue from a combination of open-source and proprietary software.

More from Technorati, this time a new authority weighting mechanism. Says Scoble: I’m not sure how useful it is, but if you search on a general term like, say, “photography” it does seem to bring back results with less noise. But, maybe you want more noise. Well, it’s up to you now! You’re the gatekeeper! I’ll play more with it later. What do you think?

Later, more from Mike Arrington who says “the slider is a bit buggy but works. This is another good way for people to sort results to find what they are looking for.”

Says Technorati CEO David Sifry — “The chart below shows the attention curve once you get past the blogs that look just like mainstream media above. It is important to note how long the long tail really is: this chart at this scale doesn’t show it - the long tail of the blogging world goes out to 27.2 million blogs. To give a sense of scale, if this chart was kept to the same scale and I printed out the additional sheets necessary on regular 8.5 x 11 inch sheets of paper in landscape mode to show the entire long tail, the length of the complete graph would be about 120 pages long, making the entire chart about 110 feet long!”.

Yahoo states that The Yahoo! User Interface Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, HTML and AJAX. The UI Library Utilities facilitate the implementation of rich client-side features by enhancing and normalizing the developer’s interface to important elements of the browser infrastructure (such as events, in-page HTTP requests and the DOM).
