In my copious spare time these last few weeks, I gave a Tech Talk to some local users' groups in Google's Ann Arbor office, "Test Driven Development in Python: A Quick-start Approach". I was deeply impressed at the quality of technical folk I met there, some of whom had actually written some of the programming frameworks I use at Google. I took some pics of the audience from the speaker's POV, my first use of an iPhone for such an application.

Winston Tsang was kind enough to have taken some of his own photos of the event; I particularly like this one:

Time to pop my head back up into the blogosphere. I've got a few moments to mention what many of my friends have known for a while: I've moved to New York City for school, as an undergraduate (junior) transfer student in biochemistry at Columbia University, pre-med. These last few months have been among the busiest of my life to date... scratch that, these have indeed been the busiest.

I bit the bullet and did the Facebook thing: it was damned near useless to me before, now it's indispensable. Having spent far too much time there, I'm turning my attention back here. More later, stay tuned...

Once again:

"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects."

More, from our recent weekend sailing, in the shipping lanes outside the Golden Gate Bridge:

The same U.S. Federal Government that expects us to "trust" them with personal data extracted by threat of prosecution - the "American Community Survey" - recently announced the theft of sensitive personal data of 26.5 million of us former military who've been discharged since 1976. My friend Dave alerted me to the story a few weeks ago, and yesterday I received a letter from the Department of Veteran Affairs cautioning me to carefully scrutinize activity on bank accounts and credit cards. Way to go, FedGov... you unaccountable fuckups.

Dear Veteran: The Department of Veterans Affairs (VA) has recently learned that an employee took home electronic data from the VA, which he was not authorized to do and was in violation of established policies. The employee’s home was burglarized and this data was stolen. The data contained identifying information including names, social security numbers, and dates of birth for up to 26.5 million veterans and some spouses, as well as some disability ratings. As a result of this incident, information identifiable with you was potentially exposed to others. It is important to note that the affected data did not include any of VA’s electronic health records or any financial information.

I'm not used to sitting back seat in a small plane. Tonight I did sit backseat, during someone else's instrument training (missed approaches, VOR/RNAV/GPS approaches, etc.) and found I learned an incredible amount about instrument flying that is sometimes hard to absorb when you are in the hot seat (as I usually am).

I took the opportunity in the back seat to watch the plane's altimeter over the PIC's shoulder as I correllated it with altitude readings I was taking with the SU-1 barometer modification on my Yaesu VX-5R handheld HT. At 4000 and 5000 feet altitudes in the San Francisco Bay area, over 2 hours of flying with reported surface barometric pressures of between 29.94 and 29.98 inches of mercury, without calibration, I was getting agreement ranging from 0 to 200 feet. It'll be interesting to see how much better the agreement is after I RTFM and do a pre-flight calibration.

There's nothing like hauling your ass out of bed, making the trip to the airport or marina, and just getting out:

This was a few miles out on the ocean side of the Golden Gate Bridge. Bright sun, great swells. I slept very, very well last night.

I wish to have no connection with any ship that does not sail fast; for I intend to go in harm's way.

The Dissident Frogman has incorporated my Japanese translations of his popular "Support Denmark" banners into his multilingual contributions archive page.

My thanks to knowledgeable friends Mariko and Garth for their thorough critiques of my pre-final draft. Thanks also for feedback on the issue of translating the original phrase "the legacy of the West", which was problematic, by these people on the honyaku mailing list: Richard Thieme, Peter Durfee, Benjamin Barrett, J.C. Helary, and James Sparks.

Don't ask me why I was using this term in conversation - many of my conversations would be surprising if one dropped into the middle of them - but my interlocutor just now heard "Pure Evil" when what I'd actually said was "Prairie Vole." Heh.

I'm going through a year's worth of iPhoto archives and found this, taken in organic chemistry lab by my friend Jenny... me in Maximum Nerd mode:

I took a break from studying this evening and visited a number of local stores to buy Danish food and booze products. Here's what I came back with, minus duplicates (I had to buy more than one of the tins of ginger cookies):

From left to right, purchases from various stores in Cupertino, California:

From Trader Joe's:

• Rosenborg Danish Blue cheese
  
• Silver Goat Organic Feta cheese
  
• "The Queen's Cookies" Ginger Spice Cookies (made in Denmark for Trader Joe's)
  

From Whole Foods:

• Denmark's Finest Havarti cheese
  
• Denmark's Finest Havarti cheese with dill
  
• Rosenborg Danish Blue cheese
  
• Blue Danish Castello Triple Cream cheese
  
• Fontina Danish Cheese
  

From Safeway:

• Denmark's Finest Fontina cheese
  
• Denmark's Finest Blue cheese
  
• Primo Taglio Havarti with Dill cheese
  

Especially notable and tasty are the ginger spice cookies made under contract in Denmark for Trader Joe's:

The thing that's missing from the first picture above: Danish beer. None of the three supermarkets above had any Danish beer - assumedly Tuborg and Carlsberg - and the one place I think might have such beer (Cost Plus World Market) closed tonight before I could check out their stock. I'll try there tomorrow night. In the meantime, I'm enjoying my Havarti with Newcastle Brown ale tonight.

I encourage all of my readers to participate in this Danish buycott.

I've been too busy to blog the last few weeks: heavy school load and lots of travel. Your guess where I was last weekend:

Four weeks ago, I had the pleasure of attending a Halloween party in Manhattan. I wasn't prepared with a costume, unless you count my normal get-up below as, um, "Visiting Silicon Valley Guy." On the left is Perry Metzger who is, ahem, a eusocialist insect:

Two days ago, I bought a copy of "Mathematica 5.2 For Students" from the campus bookstore for $150 after tax. This is the same software that sells for around $2000 after tax to non-students. It's a fantastic package, and I'm happy I bought it. However, yesterday, after having already installed a copy on my home's dual G5, I tried to install a copy on my PowerBook. Wolfram's licencing scheme doesn't allow that: I could either buy their $100/year "Premium Support" contract, which would allow me to run other copies on other nodes, or buy another copy. If I'd paid full boat for the original copy, that might have made sense, but at the student discount, it made more sense to actually buy another package entirely. FYI for science and engineering students.

First day of school after summer break; school is on the quarter system. This morning's class was the first day for me of 4th quarter calculus (vector calculus with applications, partial derivatives, and multiple integrals) taught by the reputedly toughest math instructor on campus... which is why I chose him. I found out that not only are all the quizzes given without notice: so are the exams! No kidding. This is going to be fun to watch. I'm taking the guy seriously about the Importance of Being Earnest about our study habits, and am wondering how many of the rest of us will be doing the same.

A gift from my training partner last night, and proof that padded training weapons are a good idea for some types of waza:

That's from the end of a 6-foot hickory pole, received during a sword evasion drill (sword in my hand, bo in his.) I was fortunate: my training partner had enough sensitivity to have placed the tip of the hickory right down across that eyelid into the left zygomatic arch. Pretty cool, actually.

I'm rested now and recovered from last weekend's attendance at the 4-day tactical shotgun course at Front Sight Firearms Training Institute near Las Vegas, Nevada. I surprised myself by making Distinguished Graduate, so I'm now qualified to come back to attend the 4 Day Advanced Tactical Shotgun course. On the second day of training, Greg Carroll snapped this pic of me after the two of us had done our respective runs through the outdoor canyon "clean the hostage takers out" simulator exercise:

The (visible) firearm is my Benelli M1 Super 90, with a nylon tactical sling and a GG&G M3 Tactical Illuminator mounting rail in the 2 o'clock position on the foreend, not the 10 o'clock position GG&G recommends on their website (experience in a previous course having shown me that, as a right-handed longgunner, the 10 o'clock position allows the light to bump on.)

I'd last done a tactical shotgun course about 4 years ago, and so I was quite interested to see how training doctrine had changed in respect of that weapon at Front Sight. The men in the evolution I attended - those 13 in the class who were there for the full 4 days - were all at least previous attendees at another weapon systems class (e.g. defensive handgun, practical rifle) so the class was run at a slightly accelerated pace befitting the audience. Attendees were about evenly divided between cops, active duty military (a Marine heading back to Iraq soon) and private citizens, all of whom were treated exactly the same by the instructional staff, the excellent Chuck Burnett and John Pierson.

One difference I noticed was the much heavier emphasis on incorporating movement, keeping the fight dynamic, and training that way to the limited extent allowed in the "square range environment." I was particularly pleased that, after the Monday (4th day) afternoon skills test, and the "load and go" indoor tactical simulator, I was allowed to do several rounds of 2-man team shooting on the move, with my new friend David L. Loads of fun, and I was pleased to find that a walking skill I'd been cultivating the last few years, walking fast with very short tank-tread heel/toe action to keep the hips and shoulders on level planes, allowed me to get good hits moving both forward and backward, without muzzle bob.

I'm at a level of membership at Front Sight that allows me to take any firearms course free for the rest of my life, much like some golf club memberships. So, I get to take these courses again and again, which allows me not only to revisit, revive, and refine my skills, but also to work out equipment issues. I've discovered I really don't like the Lyman TacStar SideSaddle mounted on the left side of the receiver: it catches on my clothing, when loaded it dampens recoil (and hence reliability) on this recoil-operated weapon, and with the standard provided cross-receiver screw, was coming loose even though I'd installed it properly and Lock-Tited it. I guess a couple of thousand rounds will do that to the Lock-Tite. That, and I'm leery of over-tightening that screw for fear of impeding bolt travel. Oh, and there's the issue of potentially "egging out" the screw holes on the aluminum receiver. My friend David assures me that, should I care to keep the SideSaddle, I can send the weapon to a gunsmith who specializes in Class 3 firearms with aluminum receivers, experienced in setting up weapons to resist receiver failure, but I'm going to switch to keeping my slug rounds on a belt carrier anyway.

Nor am I going to solve the "problem" of having extra ammo by changing out the tube magazine from a 5 to an 8 round capacity. This is my home invasion repellant device... if I can't solve The Problem with what's available in that weapon, then I'm in a very serious situation indeed. I'm more and more preferring lighter, more maneuverable weapons the more I train, with as few bells and whistles as I can get away with. I've heard more than one long arms instructor over the years comment on how students will arrive at a course with their all-singing, all-dancing Space Gun rigs, everything mounted everywhere, only to find themselves quickly shedding equipment after the first day... especially when training in the 105 F degree desert heat. Heh.

Recommendation: check out Estate Cartridge's low-recoil 12-gauge 9-pellet 00 SWAT loads. I've used this buckshot at a previous shotgun course, and had made the decision to attend this most recent course with too little lead time to order more of the same for this class. So, I had a mere few dozen of them to use at various times during this course, instead using a mix of Winchester and Federal buckshot for most exercises. No comparison. At half the price of Federal, the Estate-branded cartridges gave outstandingly tight and nicely distributed (e.g. no annular "donuts of death") patterns, turning heads on the firing line and eliciting a number of "what are you shooting, man?" enquiries.

I had the pleasure of remaking the acquaintance of at least one old friend, who was taking a course on an adjacent range. Additionally, I was happy to have a couple of libertarian friends, longtime (but previously untrained) gunowners, take the full 4 Day Defensive Handgun course on the same weekend. Both men, Alan and Chris, came away from the experience very much more competent than when they arrived.

An interesting blog article about the use of dendrimers in targetted drug delivery systems, sent me by Tom Burroughes in London.

University of Michigan scientists have created the nanotechnology equivalent of a Trojan horse to smuggle a powerful chemotherapeutic drug inside tumor cells – increasing the drug's cancer-killing activity and reducing its toxic side effects.

Previous studies in cell cultures have suggested that attaching anticancer drugs to nanoparticles for targeted delivery to tumor cells could increase the therapeutic response. Now, U-M scientists have shown that this nanotechnology-based treatment is effective in living animals.

This type of news carries a special type of urgency for me, as I've recently been informed that my good friend Chris Tame, in London, has been diagnosed with epithelioid angiosarcoma of the bones (spine & hip so far.) His oncologists are working hard to find the primary source of the cancer. In the meantime, any new developments in the effectiveness of chemotherapy with short & medium term time horizons are of great personal interest to me and my friends.

Seen in an elevator in the office building where my friend Serin works:

In the heart of Beijing is the huge, well-stocked Wangfujing Bookstore. If you need maps, there are thousands of them available on the first (ground) floor, just inside the main doors. English-language books can be found on the 3rd floor. Here's a pic I snapped with my Treo 650 cameraphone:

I just got back from a meeting of an organization of which I'm a member, and was talking with a Polish acquaintance at the potluck which followed. We were discussing the until-recent history of Russian occupation of his country, and he told me that some Poles he knew had during that time advocated "Layered Communism":

"Layer of Communists, layer of sand, layer of Communists, layer of sand..."

Not only did I indulge myself with scorpions in Beijing last week, I also had snake meat and silkworm pupae. I've eaten plenty of snake, and this one was undistinguished (they're usually pretty rubbery), but the silkworm was new to me: a soft, pulpy interior in a paper-thin skin. I didn't have more snake later, but I did follow up with another silkworm grub skewer a while later.

Beware, beware of Baijiu! Within my first two hours in Beijing, I was taken out for kebabs and beer by my friend Serin. We met this affable guy, Ken, who'd enquired "Naguoren? (where ya from?)" and offered me one of his sealed shot glasses of baijiu. This was an 80-proof (40%) standard formula. After two shots, he brought out a bottle whose name translates from Chinese simply as "56 Percent." We shared that bottle. Apparently, I pulled out my Sony CyberShot to Capture the Moment:

I tried red eye reduction in iPhoto in an attempt to clear up my eyes in this photo, but apparently, the red-eye in this case is not a camera artifact.

I paid dearly the next morning for this act of intercultural male booze bonding, comparable only to an episode I experienced after boot camp, half a lifetime ago, when I swore, "I'll never drink that again."

One afternoon last week I rented an electric boat and plied around the north lake in Beihai Park. After returning the craft to the boathouse, I came across this guy doing taijiquan near the shore, practicing a jian form:

When he'd finished several iterations of the same form, he walked over to the bench where a couple of older women had been watching intently. He then started pushing the tip of the jian into the bench near them! What the hell?

Ah... it was a collapsing practice piece, neatly converting into an 8-inch assembly, which he then slipped into the carry pouch his wife held out for him. Neat! I wanted one of those jian then and there, but didn't have time left in the trip to shop for one. Rest assured it's on my shopping list for my next Beijing visit.

A little walking-around food (or "little food that was recently walking around") in Beijing's Wangfujing: Yanjing beer and scorpions. These little buggers are actually very good indeed. I've had scorpion once before, a different variety with a thicker, blacker thorax, in Thailand, also spiced, and also very good.

Last night, before leaving Beijing, my friend Serin and I had a late night snack at a small neighborhood shop specializing in kebabs and Hui specialties. It was pretty chilly outside, so we ordered some comfort food, such as this mutton bone soup, with the shafts cracked to expose the marrow, straws provided for convenience:

I'm a big believer in getting out of town on spring break:

Speaking of good martial arts training, which I just mentioned I undertook last weekend with Don Angier (and the weekend before with great teachers from my own art), I just stumbled across this Jan 2005 article by Peter Boylan, "The Costs of Training with the Best" author of "Angry White Pyjamas: A Scrawny Oxford Poet Takes Lessons From The Tokyo Riot Police" (which I've read and recommend).

Boylan has some good points to make, and some sad observations to share.

I mentioned here a couple of years ago that I attended a seminar given by Don Angier of Yanagi Ryu Aiki Jiu Jitsu. I missed last year's event in northern Californa, but I managed to make this year's event last weekend. I attended both days (as did another Bujinkan practicioner), and met one other Bujinkan student during the Sunday session at Aikido of Diablo Valley.

As has always been the case with Don's seminars, I enjoyed it immensely. Both days were Yanagi-style taijutsu training, no weapons this time (e.g. the jojutsu we did in April 2003.)

The first day, we did 3-man training involving breaking from 2-attacker both-arm wrist grabs (morote in aikido parlance). The second day, we did 2-man Yanagi "kiri dori" with reversals. Both days ended with recap training.

As usual, the training was incredibly useful: the principles of Angier's art are shared with our own, with an interestingly different emphasis on how to convey them. I didn't attend with the intent of "learning their art" - that really only happens with core Yanagi students, in their dojo environment, as is the case with us and our art - but what I do expect, as I've experienced in previous years' training with the Yanagi folks, is that I'll be able to see aspects of our own art from an outside perspective.

One solid claim I can make for training with these guys is that I'm forced to re-examine all the "unclean" (or sloppy) elements in my own movement.

Really, I can't recommend highly enough that Bujinkan students take the time to attend a seminar by this incredible 73 year old practicioner of a rare Japanese family art.

I should also add that the people I trained with, mostly aikidoka, were very good training partners, and incredibly welcoming, which made the experience all the more rewarding.

On a mailing list I frequent, list owner Mike Lorrey took an unfair swipe at an old friend of mine, libertarian science fiction novelist L. Neil Smith. I forward the message in its entirety, and Neil took the time to respond to Mike in an essay released today, "Under False Colors."

Mike has quickly responded by taking the argument to his own blog, in a post counter-titled "Under Honest Colors."

The first principle is that you must not fool yourself -- and you are the easiest person to fool. So you have to be very careful about that. After you've not fooled yourself, it's easy not to fool other scientists. You just have to be honest in a conventional way after that.

I would like to add something that's not essential to the science, but something I kind of believe, which is that you should not fool the layman when you're talking as a scientist. I am not trying to tell you what to do about cheating on your wife, or fooling your girlfriend, or something like that, when you're not trying to be a scientist, but just trying to be an ordinary human being. We'll leave those problems up to you and your rabbi. I'm talking about a specific, extra type of integrity that is not lying, but bending over backwards to show how you're maybe wrong, that you ought to have when acting as a scientist. And this is our responsibility as scientists, certainly to other scientists, and I think to laymen.

For example, I was a little surprised when I was talking to a friend who was going to go on the radio. He does work on cosmology and astronomy, and he wondered how he would explain what the applications of his work were. "Well", I said, "there aren't any". He said, "Yes, but then we won't get support for more research of this kind". I think that's kind of dishonest. If you're representing yourself as a scientist, then you should explain to the layman what you're doing -- and if they don't support you under those circumstances, then that's their decision.

One example of the principle is this: If you've made up your mind to test a theory, or you want to explain some idea, you should always decide to publish it whichever way it comes out. If we only publish results of a certain kind, we can make the argument look good. We must publish BOTH kinds of results.

I am really, really enjoying my biology class, a concentrated term of cell & molecular biology. Students in this program spend about four times as much time in lab, learning industrially useful techniques, as do students in comparable programs in the University of California system. In the last three weeks, I've had hands-on time doing protein electrophoresis, conjugation (bacterial DNA transfer), and DNA electrophoresis. Here's an image of our team's first DNA gel:

The DNA is from purified coliphage Lambda virus, 48,502 Kb (kilobases) in length. Lane 1 is pure, uncut DNA. Lane 2 is DNA restricted (cut) by Eco RI enzyme, Lane 3 restricted by Hind III, and Lane 4 by both (the restriction sites are different, resulting in more, smaller DNA fragments.)

Lanes 5 through 7 are subsamples taken from 2 through 4, subjected slowly and thoroughly to the action of the enzyme DNA ligase, resulting in outrageously long, randomly recombinant strands.

The gel is purified agarose treated with ethidium bromide. The image above is a high-contrast Polaroid of the gel UV-transilluminated to fluoresce in the visible spectrum (reddish orange, here shown in black and white).

This stuff is outrageously fun.

My Bujinkan teacher Dale Seago mentioned this a few days ago:

Some VERY good pages on Japanese armor which give a clearer understanding of why armored fighting methods are the way they are; also sections on historic Japanese clothing & accessories, the design and layout of Japanese estates during the Heian period, etc.

For those with a bent toward Humphreyesque "cultural detective work", there's an essay on "Rape as the First Act of Romance in Heian Japan" which makes it pretty clear that the feudal Japanese viewed some things quite differently from the way we do in our society today... (Whaddaya mean I should wait 'til the 3rd date?!?)

Speaking of armor... I just got back from the dojo tonight, after having had my first experience training with around 60 pounds of it (2 vests, helmet, a ruck loaded with books and a medicine ball, and ankle weights), and my lungs hurt: what an ordeal! This year's training emphasis is going to take some getting used to.

People who will not take the trouble to raise children should not have them.

Today after work I headed up for Thursday night Bujinkan training (the weekly outdoor session, which I'd been missing until recently due to school), and had a great time tonight. Before heading to San Francisco, I did a quick search for late night coffee shops with free wireless internet access, located within a reasonable drive of the training park, and found the Samovar Tea Lounge in the Castro/Mission district.

I'm sitting there right now, having "Russian High Tea" way too late in the day. Service includes all-you-can drink high-octane self-serve tea from - you guessed it - a samovar: "dilute to taste" is the operative term. This place is genuinely cool, and I highly recommend it.

About the "just because I can" thing: an acquaintance of mine, Marc Stiegler, once wrote in one of his novels that it's vitally important to maintain a childlike sense of wonder about the world. Here I am, sitting in a friendly place, an oasis of light in the darkness, warmth against the wind, music from the walls, and good food I would never have thought of making myself, talking to people in other cities on a 4-pound device that I use to bring me money... life is a good thing.

Monica, you can take my blog off the "Missing in Action" list on your blogroll: I'm out of school for three weeks, concentrating on work but taking a few minutes a day to blog.

Speaking of school, the last few weeks of organic chemistry were split between the standard track material (in this case reactions of alkynes) and a series of lectures on NMR (nuclear magnetic resonance) in depth. When I return to school, our department's new NMR machines will be in place, so this preparation is essential to actually using these machines productively. I'm really looking forward to adding NMR to my toolkit.

To those of you with cats: have you ever noticed how they immediately establish themselves atop piles of freshly laundered clothing?

We finally started into dissections in biology lab tonight. My own specimen was this rather stout, well-endowed female Ascaris lumbricoides, an intestinal parasite of humans:

I'd suspected that although our college's brand-new science center was state of the art in facilities, our gear would be knackered, so I brought my own gear (probes, pins, scalpels, various forceps, etc.) just in case. I was correct in my assessment: all the school-supplied gear was thrashed. One other guy in the lab, an Air Force PJ (USAF Pararescue) who's med-school bound, brought his own gear too; it was interesting to compare kits.

Since this specimen was pseudocoelomate in its body plan, there was no mesentary tissue to complicate the incision process. I was able to do really well with a #15T surgical blade: small enough, with a fine tip for starting an incision, but a sufficiently curved blade belly to continue incisions without nicking the viscera.

One gets the impression after laying this open and spreading its innards with a blunt probe that it is all uterus, wrapped in oviduct... two strands of Top Ramen cloaked in angel hair pasta. This thing is even more dedicated to reproduction than it is to feeding. Brrrrrr.

Lucy:

I seemed to have been the only person this morning other than my instructor to have paid attention to the warning on the bottle of crotyl chloride, "Danger: lacrymating agent!"

It was also amazing to see the number of people dispensing silver nitrate without gloves... low toxicity risk, but high chance of Rorschach tattoos on one's hands (hint: silver nitrate is photosensitive.)

Thanks to those of you who've sent email wondering if I've dropped off the face of the earth. I haven't (dropped off anywhere, that is.) It's my first week back at school (organic chemistry, calculus, and biology) and I've also been busy with work and visitors from out of town. I expect I'll be blogging again semiregularly in the next couple of weeks.

For the time being, also, this blog's comment facility is still malfunctioning. It's been a low priority, given my recent time crunch, to track down the root cause. My apologies for that; I will fix it sometime in the near future.

Damn: 2 years of running this blog using MovableType with no problems, then 2 users in the last 2 days tell me they're seeing this when they try to post comments here:

"Your comment submission failed for the following reasons:

You are not allowed to post comments.

Please correct the error in the form below, then press POST to post your comment."

I very rarely block users from commenting here, and certainly wouldn't have blocked the two of you who've told me in private email. I apologize for whatever is causing this problem for you, and ask your indulgence while I try to troubleshoot the problem. Unfortunately, I won't be able to attend to this until later tonight; thanks for your patience!

A few days ago, I finished reading Henry Petroski's "The Evolution of Useful Things: How Everyday Artifacts-From Forks and Pins to Paper Clips and Zippers-Came to be as They are," a breezy exposition on the origins of things most people take for granted, usually considered not worth wondering about. In a similar vein, and coincidentally well-timed, Curt Howland forwarded me yesterday a pointer to an essay lauding one artifact in particular, "In Praise of the Oh-So-Dependable Cardboard Box," by Russell Roberts.

I'm reminded of an essay I read in the summer of 1990, a copy of which was given me by its author, Phil Salin, at a house party in Palo Alto, before leaving for my 1st work assignment in Europe. The essay, "The Ecology of Decisions, or 'An Inquiry into the Nature and Causes of the Wealth of Kitchens,'" opened my eyes to what Petroski often refers to as the "artifactual intelligence" encoded in the seemingly mundane, the things we don't consider.

Phil's work, by the way, is maintained on the web by friends who deeply care about him: he succumbed to stomach cancer sometime around 1993, and is presently in cryostasis at the Alcor Life Extension Foundation. I didn't have the chance to personally thank Phil for his strong influence on my thinking, but I hope to have that chance someday.
