Yikes

Here's something that would start you thinking about how long you can tread water: losing an engine over two hours out from HNL on an ETOPS flight.

Cell phones, free talks by McKusick

Since the topics aren't related, this should be two postings. First, cell phone spying and criming have been in the news lately:

• From IEEE Spectrum, details of how "extremely smart hackers" tapped the Prime Minister of Greece's cell phone. Wired has an article about how CIA agents were tracked through Italian cell phone networks.
  
• Second, two free talks by Marshall Kirk McKusick of UNIX fame, both sponsored by UC Berkeley extension, but actually located in San Francisco: "A narrative history of BSD" (the "Greatest Piece of Software Ever") on 26 September, and "Bulding an Running an Open Source Community" on 3 October, both from 5:30-7:30pm.
  

Bonus: Checkers has been solved computationally, but not in the way you might think by evaluating a game tree the way many of us were taught.

Lives (First and Second) and interfaces

Here are some links to interesting stuff that's popped up recently:

Second Life

One favorable article and two that are more skeptical: Technology Review has a very interesting article about combing aspects of Second Life with Google Earth in the article "Second Earth" (you might need to register free). On the other hand, Time magazine lists Second Life on its Five Worst Websites list here. Finally, the Los Angeles Times discusses how retailers might be bailing out.

Interfaces and design

You really need to watch this five minute video of Jeff Han discussing multitouch interfaces and their implications for collaboration. Also Bruce Sterling discusses design in this video and talks about how a typical public telephone is designed "like a cactus" versus how Google would design a public telephone.

Finally, here is a bonus link from Technology Review. Is Artificial Intelligence dead or just misguided?

Over 20,000 computer terminals!

Deep in the Alcatel-Lucent website are some videos of famous Bell Labs employees. Here's a two minute video about the UNIX operating system -- see what fashonable geeks were wearing in 1969. Hear Ken Thomson talk about making computing simple, and Dennis Ritchie about fellowship and "communal computing". Far out.

Politically incorrect

I want to see the Egyptian pyramids and Luxor, so I recognized the name of Zahi Hawass (the guy you see on television talking about antiquities) as I flipped through the July Conde Nast Traveler. But I was surprised at some of the statements he made in this interview, such as

A group of tourists who can afford to pay only a thousand dollars apiece for a trip are useless. Let them stay in their own country!

Yikes.

Traceability

Anyone who's taken a software engineering class from me, undergrad or grad, knows I like traceability:

Requirements traceability... provides critical support for software engineers as they develop and maintain software systems. Traceability helps determine that researchers have refined requirements into lower-level design components, built them into the executable system, and tested them effectively. It further helps analysts understand the implications of a proposed change and ensures that no extraneous code exists...

Furthermore, organizations building safety-critical systems are often legally required to demonstrate that all parts of the code trace back to valid requirements. Laws such as the US Sarbanes-Oxley Act of 2002 require organizations to implement change-management processes with explicit traceability coverage for any parts of a software product that potentially impact the balance sheet.

The above is from a paper in the June 2007 IEEE Computer magazine, "Best practices for automated traceability" by authors from DePaul University, Siemens Corporate Research, and iRise. The paper gets heavily into probability after the first couple of pages, so I wouldn't make undergrads read it, but skimming the paper gives an idea of what folks are doing to find and maintain those threads of traceability I'm so fond of.

Here are the links:

• directly to article in the IEEE online library (unless you have a subscription, you'll only get the abstract and reference information)
  
• a direct link to the article for Fresno State students, staff, and faculty.
  
• a direct link to the June 2007 issue for University of Hawaii students, staff, and faculty (you'll have to scroll down to the article).
  

Veggie oil tales

We've previously talked about cars powered by vegetable oil and how some states are going after tax revenue.

North Carolina is the most recent one I've heard about:

Teixeira's story began near Lowe's Motor Speedway on May 14. As recreational vehicles streamed in for race week, revenue investigators were checking fuel tanks of diesel RVs for illegal fuel.

The investigators spotted Teixeira's passing bumper sticker: "Powered by 100% vegetable oil."

"It was like some twist of fate that put me there," he said. "It was like I was asking for them to stop me."

And now for something completely different

Yesterday evening having pizza and fruit at the farm of some nearby friends we got to talking about organic, almost-organic, and traditional tree fruit farming.

I remembered that back in the day when we had an apple orchard I read something in California Farmer magazine about someone drinking a glass of malathion. This was during the medfly scare.

Well last night David knew the guy's name (B.T. Collins) but we thought it was during the Reagan governorship. Actually Collins (a republican Viet Nam double amputee) was appointed by Jerry Brown as his chief of staff. Sounds like a very interesting guy. Time magazine describes the malathion incident:

Brown's fears notwithstanding, state officials said it was safer to spray from the air than the ground. Reason: the Malathion is mixed with molasses, sugar and yeast and falls in coffee-graint-size droplets that cannot be easily inhaled. B.T. Collins, 40, director of the California Conservation Corps, gave the most dramatic demonstration of its safety: he drank a glassful of Malathion diluted with water to the concentration used in the spray.

On findagrave.com an entry quotes some of his personal "rules":

You stand up for your people. You dig your own foxhole. Don't tell your best friend who to marry. Never argue with a cop. Always send handwritten thank you notes.

Reminds me of David Hackworth, author of the very interesting About Face, not to be confused with Alan Cooper's user interface book of the same name :)

Stu Card and Don Norman

The Franklin Institute posted two brief, layman-level videos of recent HCI award winners.

Stuart Card

from Xerox PARC for human-computer interface achievements

Donald Norman for user-centered design.

both videos are easy to understand and interesting, and short. The Franklin Institute has been around for a while, and describes the awards as:

For 182 years, The Franklin Institute has honored the greatest men and women of science, engineering, and technology. The Franklin Institute Awards are among the oldest and most prestigious comprehensive science awards in the world.

You can also listen to an audio podcast about human-computer interaction, and about how the committee chose Stu Card for the award. They even talk about Fitts Law!

Computer people and their tiny airplanes

I've previously posted about Jef Raskin's take on why planes fly: here and here. Simson Garfinkel blogs about meeting Raskin and marveling at his radio controlled gliders. Raskin died in early 2005, but Garfinkel finally built and flew a glider: "After five years, I make good on my promise to Jef Raskin". You can see a video of Raskin's workshop with lots of airplanes, and two secret doors :)

The inspirational story of an 'overnight' success

The May-June 2007 issue of ACM's interactions has a two page article about how Harmonix's Guitar Hero took off after Best Buy put the game on kiosks. If you are a Fresno State person you can access the article here, and if you are a University of Hawaii person you can access interactions and then go to the issue.

But more interesting than the interactions piece is this take at GameSpot News: scroll down about one screen to "Alex Rigopulos: Whose dream is it, anyway?". There is also a link to really lousy audio. A slightly better article is here.

My nemesis

A significant portion of my late spring is weed whacking star thistle, one of the nastiest weeds around. The Nature Conservancy does the same thing, but on a much larger scale, using a helicopter (no, not upside down as a weed whacker). There's a good article in the latest Nature Conservancy magazine (which lots of pictures) -- here's a quote:

Standing on the east rim of the canyon, the river thousands of feet below, you can see a lot of that ground, and it’s all at risk, particularly from a weed called yellow star thistle.

“It’s nasty stuff,” Talsma says. “It’s just a crying shame.”

... The plant first came to North America from Mediterranean countries in tainted loads of clover seed or alfalfa shipped to California in the Gold Rush days. From there, it has marched steadily east. It bears a pretty yellow flower, but that’s the only nice thing to say about it.

Here's even more pictures, courtesy of UCB.

Jumpseats, Cars, Beaches

I've been reading the blog of a NWA 757 pilot. Recently he was in the jumpset of a Hawaiian Airlines 717 from Honolulu to Hilo, and soared on the north shore. Interesting pictures in both, but it sounds like he prefers his 757:

After all, if I miscalculate a bit, I have those magnificent, high compression, high bypass, twin rotor, axial flow, turbofan, Pratt & Whitney R-2040's, producing more than 80,000 pounds of thrust to bail me out. In thrust we trust, let's fire this baby up!

Changing the subject, the annual report of water quality of California beaches is available. Because of low rainfall this year there wasn't as much contamination from run off, but I did find this paragraph:

In a recent study on enteric viruses at Imperial Beach and the Tijuana River mouth, researchers reported a number of hepatitis A virus strains. Because untreated human fecal waste from Tijuana sewage outfalls is a major pollution source to coastal waters near the US/Mexican border, human fecal bacterial densities (E. coli and
Enterocci) during wet weather exceeded state water quality standards in 86% (12 of 14) of the samples in the study. Exceptionally high concentrations of these human fecal indicator bacteria were significantly correlated with high concentrations of hepatitis A virus and enterovirus. Three strains of poliovirus were also detected

Polio? yuck.

Changing the subject again, an interesting paper in the Proceedings of the IEEE volume 95 issue 2 (2007) about the software running in modern cars. The article is fairly understandable and not too technical. Here's the citation:

Engineering Automotive Software. Manfred Broy; Ingolf H. Kruger; Alexander Pretschner; Christian Salzmann. Page(s): 356-373 vol 95 issue 2 (2007). Digital Object Identifier (DOI) 10.1109/JPROC.2006.888386

If you are a Fresno State person, you can click on http://dx.doi.org.hmlproxy.lib.csufresno.edu/ and paste in the article's DOI (10.1109/JPROC.2006.888386).

Enhanced color vision

Speaking of HCI, another topic in my class is enhanced color vision. I first read about this in Glenn Zorpette's article "Looking for madam tetrachromat" (you can read a plain text version or see the article in the Red Herring archives if you log in). The idea is that there are women with extra photo receptors.

This has also been a good Damn Interesting story (with some nice illustrations).

I was reminded of this again because the May/June 2007 Technology Review had a short review of a recently published Science article describing genetically engineered mice with an extra photoreceptor. Eventually you'll be able to see the blurb in the Tech Review "From the Labs" archive, but until then you can read the abstract of the Science article.

Actually, I fooled around with different URLs and I think you can see the May/June 2007 issue of Tech Review before it is officially released. You might want to check out the Objects of Desire photoessay, in addition to the enhanced mice.

Time: Subjective and Objective

One of my favorite things to have HCI students read is Tog's short description of an experiment showing the difference between objective and subjective time. (Tog also talks about the manipulation of time in the classic "Principles, Techniques, and Ethics of Stage Magic and Their Application to Human Interface Design" in which he talks about the mirrors-by-the-elevators anecdote (also repeated by Ackoff & Rovin in "The Ups and Downs of Elevators" section of Beating the system: Using creativity to outsmart bureaucracies and also appearing as a Joel on Software topic)).

Anyway, The whole point of this post is that Tog recently posted an update including a funny example of airlines that "get it" and "don't" when it comes to objective and subjective time. You can skip all that stuff above and read this :)

Santa Barbara whales

A gray whale was swimming around by the wharf in downtown Santa Barbara (still alive, but maybe suffering from the “Unusual Mortality Event" that's killing marine mammals.

A nutty student tried to steal teeth from a recently washed-up sperm whale and was arrested.

P.S. about Einstein

I saw part of the X Files movie today but I'd forgotten that some was filmed at the Athenaeum also. But I can't remember which part. I also remembered that I saw some filming of a movie about Richard Feynman on the Caltech campus. Matthew Broderick played Feynman. Didn't see Matt on campus though. Or Feynman :) Although Jim Kiper and I attended a talk that Oliver Sacks gave in Cal Tech's crazy looking auditorium.

My Einstein inadequacy

On CSPAN's BookTV this weekend I saw a brief talk by the author of a new book on Einstein. This reminded me of back in my JPL days I got to stay in Einstein's apartment at the CalTech Athenaeum. There was a Joshua Reynolds painting over the fireplace, and the patio overlooking the campus was great (you can see pictures of both here). That night I felt pretty dumb and had trouble falling asleep.

But, it could be that was because it was also the night of the explosion and crash of TWA 800. I sat on Einstein's couch (OK, I think it wasn't the original :) and fiddled with the rabbit ears on the ancient TV (also non-Einstein) to watch news coverage of the accident.

I always thought it was funny that while I was semi-regularly staying at the Athenaeum there were only rabbit-ear TVs, and no air conditioning, which made some summer Pasadena nights pretty unbearable (one night at 2am it was 92 degrees F in the room). I think both of those have been remedied (and a guest elevator installed).

The Athenaeum is known for it's food (I mostly ate downstairs in the Ratheskeller pool hall), and there is even a reference to Einstein in this foodie review.

BTW, I also stayed in the Millikan Suite, but wasn't as intimidated since I don't think he actually lived there :)

One more bit of trivia: the dining room scene of Beverly Hills Cop was filmed at the Athenaeum:

"If you saw Beverly Hills Cop, you've seen the Athenaeum," says Arden Albee, a retired professor of geology and planetary science who is chairman of the club's house committee. The banquet room was used in a food-fight scene in the 1984 movie, which starred Eddie Murphy. The club's porch was used more recently in The Wedding Planner, starring Jennifer Lopez, and features real weddings as well.

The quote is from an article in The Chronicle of Higher Education available only to subscribers, or to anyone who Googles athenaeum albee and clicks "cached" :)

One more bit of trivia: during one of my JPL summers I stayed in Dr. Albee's guest house in the backyard. I think they pretty much forgot that I was staying there since they seemed surprised when I would come up to the main house to pay the rent :)

Not exactly UFOs, but strange flying things

Sporty's Pilot Shop has the weirdest stuff sometimes. Like a cannula that you attach to your headphones with double-stick tape. I never thought of jamming tubes in my nostrils and then taping them to an ear.

Another thing is an ordinary looking ice chest, with a hole cut in the lid and a fan attached. The idea is you fill the chest with ice and water, and run the fan to cool your cockpit. Seems like something that I would have done in 1976 driving an un-airconditioned car to the midwest.

But, really, for weird, this is right up there. Could be useful in this summer though :)

disposable or reusable revisited

Back in October I posted something about how many times you'd need to reuse a ceramic (or glass) mug to use less energy per use than drinking from a disposable cup.

There was something today on digg about the topic. Since digg can be annoying, here is the link to the cited report. This is probably where the "you'd need to use a ceramic mug a thousand times to break even" comes from -- according to professor Martin Hocking's calculations, the ceramic-foam "break even" point is 1006. A quote:

The results are extremely sensitive to the amount of energy the dishwasher requires for cleaning each cup. Hocking's choice for the dishwasher, requiring 0.18 MJ/cup-wash, is barely less than the manufacturing energy of the foam cup, 0.19 MJ/cup. If Hocking had chosen even a slightly less energy-efficient dishwasher as his standard, then the reusable cups would never have broken even with the foam cup.

The lesson of this life-cycle energy analysis is that the choice between reusable and disposable cups doesn't matter much in its overall environmental impact. One should use one's best judgement.

Bonus tidbit: earlier in the week I was in a meeting where someone who knows a lot about local health statistics opined that contrary to popular local belief, the number of emergency room visits for "asthma" don't peak during "bad air" (high ozone) days. The visits peak during high allergy days :)

Duh.

Here is a page of statistics that looks ... misleading. For example, the central valley has a higher percentage of kids with asthma. OK, how much higher. The rate for the valley is 11%, the bay area 10%, the state (9%), and LA (8%). Three percent difference? Is that statistically significant? Could there be something else going on here, like, oh, family income? Access to health care? Living where there is a ton of pollen in the air? :)

Also, when you look at "all ages" and see that Fresno County is 13%, yet Kern, Tulare, and San Joaquin counties (two out of three with at least as bad air quality :) are 9%, well that makes you wonder about the data :)

I've always thought it interesting that living around cockroaches is bad for asthma.

Back to ages 0-17. As above, the central valley rate is 11%. Assignment: What's the national average for ages 0-17?

How about this (emphasis added):

In 2003, most U.S. children under 18 years of age had excellent or very good health (83%). However, 10% of children had no health insurance coverage, and 5% of children had no usual place of health care. Thirteen percent of children had ever been diagnosed with asthma. An estimated 8% of children 3-17 years of age had a learning disability, and an estimated 6% of children had ADHD.

Isn't data interesting :)
