It’s a slow week.

AF447 is in the news still

• Miles O’Brien has a write-up on what is called the “coffin corner” and how it may have caused AF447 to stall at high altitude and break apart.

  The disturbing implication, too, is that excessive rudder input may have caused something similar to the American Airlines flight 587 accident where the tail was severed from the aircraft.

Programming

• I didn’t realize that writing equality methods in Java was so difficult. Here’s an article that explains how to do it correctly.
• Oldie but goodie: Don’t forget about Py2EXE, the utility that lets you distribute your Python application as executable binaries for Windows. This does require packaging the interpreter and any modules used, so the package size can be quite large (~2MiB for a simple application–compressed).

Random Cruft

• I bought my mother an ION USB turntable to encode all of her 45s and 33 LPs. Dad’s got a bunch, too. As an aside, I also stumbled on an interesting thread detailing the very last (inside) track on LPs and why their quality degrades. It’s really quite interesting.

I’m going to break out of the usual cycle of posting my Links of the Week threads on Wednesday. Let’s try posting these on Monday since there’s a lot going on this week that is of importance. I’ll be keeping this post updated, particularly with the Air France airliner that went down.

Biology

• The New York Times has an interesting book review on a work titled Catching Fire: How Cooking Made Us Human by Richard Wrangham. I may have to get this one.

  I recall some years ago when I had heard that cooking helped break down heavier starches into more manageable types (including simpler sugars), and that cooking is at least partially responsible for us having the brain we do. (While our brain-to-body mass isn’t extraordinary, the amount of oxygen our brains consume compared to the rest of our body is.) Anyway, it looks like Michael Savage was right and the vegetarians–not surprisingly–were wrong.

English

• The Economist has a somewhat amusing style guide on commonly misused words or words that are commonly used in a non-standard manner. Now, the reason I find this particular article humorous is because it reads more like a stupid nit-pick: there’s a significant number of words that they point out as misused when they’re widely accepted, defined, or colloquial use defines them as the speaker would expect. Granted, this is purportedly an internal style guide for their use, but I sometimes wonder if such things aren’t taken to unnecessary extremes. Here are a few examples of what I mean:
  • Demographics: no, the word is demography. Funny, but it looks like demographics isn’t a nonstandard, ungrammatical use…
  • Garner means store, not gather. Are they aware that garner can be used as a verb, meaning to gather?
  • Immolate means to sacrifice, not to burn. They have a strong case here. Though, there’s still that pesky colloquial usage thing…

  Honestly, I think they need to purchase a copy of Diana Hacker’s A Pocket Style Manual.

  Edit: I’m so used to reading British English that it dawned on me that this particular style guide is most likely limited almost exclusively to UK English. If this is the case, then perhaps it is a good exercise to observe differences between US English and British English.

Local News

• Paul Haney, a local man and former voice of NASA and public affairs official died Thursday after a lengthy struggle with melanoma.

Technology

• I stumbled upon an interesting graph of benchmark data from the “Computer Language Benchmarks Game” (formerly “Language Shootout”). The results are rather surprising. For those of you who claim Java is painfully slow, it might be worth looking at the benchmarks. This is pretty close to tests I’ve seen myself. Tomcat (written in Java) serves up static content faster than Apache 2 (written in C). Although, whenever .htaccess support is disabled in Apache, performance is reasonably close–with Tomcat still ahead.
• Speaking of Java, Gilad Bracha has a fascinating article on certain deficiencies in Java. Although Python is much slower in comparison, it does make me feel a little bit better about some of Guido’s language choices. Everything as an object has its use.

World News

• Air France Flight 447
• Update – Tuesday afternoon: Tim Vasquez of weathergraphics.com has a tremendously detailed write-up on the influence weather may have had on flight AF447. He is careful not to implicate weather as the cause but suggests it may have had an interesting impact. He also has a few plots related to where the aircraft’s position most likely was relative to the storms in the area.
• Update – Late Monday, early Tuesday: According to WikiNews, passengers had sent text messages to family members before the plane disappeared.
• On Monday, a French airliner went down in the Atlantic. AirDisaster.com has a lengthy article on this along with a picture from JetPhotos.Net of the exact aircraft involved.

• North Korea is ramping up missile development.

I’ve been busy! As a result, I haven’t a lot of links to share this week.

However, I did run into a pretty amazing German group. They really like bagpipes–my favorite! Check out some of their performances, specifically Kalifenzorn, Caput Draconis, and Chaos.

Programming

I’ve got another link fresh from the TurboGears mailing list on metaclasses in Python and how to avoid the non-strict error.

Carlos Oliveira, PhD, has a really great series on “how to become a better programmer in 30 days.” It’s a very worthwhile read for anyone, no matter your skill level.

Updates May 28th:
This sort of worries me, but there’s a group of people re-implementing PHP in JavaScript. I wish I were kidding.
