Test Driven Development in Python: A Quick-start Approach

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:

OK, time to prairie dog

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...

Quote of the Day, or "Guess what I did last week?"

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."

I like this one:

Are you one of 26.5 million veterans affected by the latest FedGov screwup?

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.

Sitting back seat felt weird tonight

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.

Another "I'm glad I woke up this morning" weekend

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

Finished Japanese translations of "Support Denmark" banners

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.

Misheard words of the night: "Prairie Vole"

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.

Me at my most Poindextrous...

Tonight's Danish products buying binge

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 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

• Primo Taglio Havarti with Dill cheese
  

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

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

Where was Waldo last weekend?

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:

It's OK if I explain the sight gag

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:

The Man with Two Mathematicas

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.

Another reason for an attitude of preparedness

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 padded training rokushaku-bo is a good idea

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

Just returned from a 4-day tactical shotgun course

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.

Dendrimers to improve chemotherapeutic delivery

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.

Another cameraphone tidbit from Beijing

Wangfujing Bookstore in Beijing

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:

"Layered Communism" in Poland

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..."

But wait, there's more

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!

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."

A quiet moment in Beihai Park

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

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.

Sucking the marrow in Beijing

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:

Three guesses where I am this week...

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

"The Costs of Training with the Best"

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.

Don Angier aikijiujitsu seminar, 19-20 March 2005, at Aikido of Diablo Valley

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.

Neil Smith calls Mike Lorrey out on the floor

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."

Quote of the Day

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.

My first DNA electrophoresis

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.

Excellent resource on historical Japanese armor

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?!?)

Just because I can.

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.

Three weeks of rest from school

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.

Tonight's Blue Plate Special: Ascaris lumbricoides

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.

Can't help myself, must kittyblog

Lucy:

Keep the fricken' lacrymators under the hood!

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.)

Still busy, not dead

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.

This blog's commenting facility is acting up

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!

The mundane things we don't appreciate

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.

A shot I didn't expect

By the title, I mean I didn't expect that my friend Andy would be taking a picture of me at this moment:

It was pretty dark in the shade of the shooting stall, in stark contrast with the sunny range, and no fill flash was used. I managed to extract a bit more information using the GIMP.

Firearm was a full-frame H&K USP in .45ACP, firing on a "hostage rescue" metal silhouette at 15 meters. Hard shot, wouldn't want to have to do that for a living. I would never seek to be in such a horrifying predicament, and certainly wouldn't want to have to use a pistol, at relative long range, unsupported, to try pulling it off. Still, one should always train for the unthinkable.

I'd love to know how & why Gmail does its thing

I mentioned yesterday that Google's Gmail service had given me 6 invitations (they'd originally given me 2) yesterday, and that I was giving them away. I got 3 takers within minutes, leaving 3.

This morning, I notice that I had not 3, but 6, invitations left. I immediately gave away two more.

The thing is, several other people I know have Gmail accounts, but I've been told by some of them that they've only ever been given a grand total of 2 invitations, with no replenishment. I'm not sure why I keep getting more... I wonder what rules Google's automation uses to determine whom to replenish with invitations? I'm guessing that it may be a side effect of the fact that I receive mail from a very busy mailing list to that account. Invitations may be granted in proportion to use. Anyone have insight to share?

By the way - to pre-empt the inevitable request from someone I've never heard from previously - I should add the caveat that I'm only giving these invitations to realspace friends or those of my online acquaintances with whom I'm friendly.

Monica White's Firefly article in The Atlasphere

Monica White has really gotten the Firefly bug: today, her extended recommendation of the series, "The Ascendance of Firefly,' was published on the Objectivist culture site The Atlasphere. It's particularly interesting to see how a Joss Whedon fan site has reacted to Monica's just-release piece.

Was that me in that commercial?

I'm answering email just now, with a local Mandarin-language cable TV channel playing in the background (2 years of Mandarin in college, gotta keep it up... besides, I admit to a silly fascination with "Pawnshop No. 8"), when I see an advert for my dentist - a part-time semiretiree who's also a professor at a local dental college - and glanced a white guy with black hair leaning back in The Chair. What the hell? Wonder if that was me... don't remember consenting to filming. I did spend an inordinate number of visits recently getting my dentition reconstructed from the effects of "overlarge crown placement... aiyah!" from a few years ago.

This reminds me... every dentist I've ever had - American, English, Filipino, Persian, Japanese, Taiwanese - seems to have been drilled in The Dark Art of Attempting Dialogue With a Patient Pinned Helpless with Cheek Retractors.

Jeezus fookin' Kee-RIST!

One of the kittens (well, year-old cats) just discovered how to push out the screen on Peggy's second-floor office window! I'm sitting here, wrapped up in my writing, and Peggy comes downstairs asking, "Where's Lucy?" and commenting that her office window's screen was now down on the side carport. We both immediately grabbed one each of the many head-banger Maglite flashlights ("torches" to my UK and Aussie friend-readers) we have sitting in various rooms around the house and ran outside to the back yard. We found her quickly, shivering under a stash of gardening supplies. She was uninjured, but apparently had been outside for a couple of hours, and was a bit dusty.

We brought her in and in a fit of guilt fed her most of a bag of cat treats. Her brother Selmak, uncharacteristically, hissed at her: I'm guessing that's his way of saying, "Goddamn, you smell funky girl!"

I'm imagining that a Chihuahua, given a similar fall, would not have gotten off uninjured, the way she did.

I'll be looking for bird carcasses in the morning. I'm hoping the yard will be littered with them. If you're going to go through an unscheduled skydive, there should at least be good hunting on the ground after the event.

Orkut sucks, time to move along

A half year ago, I was invited to join the Orkut social networking service by my old friend Perry Metzger. A half year later, I've decided that it's an evolutionary dead end: for a service "affiliated with Google," it's unusually clunky, feature-poor, primitive, and dreadfully unreliable. I've made a few good friends through it, however, and am glad of the experience, which has been useful and informative.

Interestingly, in the last couple of weeks I've gotten email from a few people I know through Orkut, inviting me to the Multiply network, an Orkut competitor which seems vastly superior in its execution. I'd ignored those invitations, being busy with other things, but tonight I took my friend Shannon Kaplan up on her invitation, and am impressed at the sophistication of the interface. I'm not convinced I need all their features - I already have my own self-administered blog, for example - but for the general public, it seems at first approximation to be an incredibly well-integrated suite.

So, if you receive an email entitled "Russell Whitaker invites you to keep in touch on Multiply," don't automatically assume to be spam. Multiply has an interesting feature - apparently driven by Orkut user dissatisfaction - with which Orkut users can export their entire network of contacts over to Multiply in order to generate invitations to the rival service. Better I should use it now, before Orkut programs logic to block that data export.

Of course, if Orkut's programmers had been sufficiently on the ball to quickly develop such program logic, they'd also have been sufficiently agile to develop new features demanded by their users... such as forum threading up to 1990 newsreader standards, perhaps?

Taking a breather to blog

I've had my head buried in a particularly frustrating programming problem, which had kept me up a couple of nights running (one of those in the fog of food poisoning), and I think I may have broken through a problem I was trying to run to ground. So, I'm treating myself to a couple of hours' blogging, before returning to work. Apologies that postings have been so thin of late.

Oh, yes: tip o' the hat to Julia Child

While I'm enthusing about food, I should point out that Julia Child would have been 92 years old today. She died yesterday, however. My maternal grandmother was born 3 months after Child's birth date; I plan to visit her in a few weeks, I'm reminded. I'm also reminded that the women in my family live a long time, though not nearly long enough, my standard being centuries, but that's of purely tangential interest here.

The modern crop of food divas and divos (the humorless Martha Stewarts and the gimicky "Bam!" Emerils) owe a debt of gratitude to Child, an eccentric of the first order (anyone else remember the Dan Ackroyd parodies?) She was a woman with a very interesting personal history (reminding me of Martha Raye, "actress and denture wearer," the only civilian buried at the U.S. Special Forces cemetary at Fort Bragg), which includes having been an OSS officer during WWII.

Child is quoted as having said in an AP interview in 1989:

"What's dangerous and discouraging about this era is that people really are afraid of their food... sitting down to dinner is a trap, not something to enjoy. People should take their food more seriously. Learn what you can eat and enjoy it thoroughly."

Sounds like someone who lived her life fully. Too bad she couldn't have stuck around a few more centuries to enjoy it even more thoroughly.

By the way, Child's original TV set kitchen is preserved at the Smithsonian.

My visit to the Quent Cordair Gallery on Saturday

About three weeks ago, I wrote that my friend Monica White had indirectly informed me (through her blogroll) of the existence of the Quent Cordair Fine Art Gallery in Burlingame, California, about a mile from San Francisco International Airport.

Well, on Saturday - on a whim - I suggested to Peggy that we head up to the gallery for the short remainder of the afternoon. We arrived about two hours before closing... and left about an hour after closing.

I'd called ahead to confirm that the gallery was, as indicated on their website, indeed open for the afternoon. When we arrived, a friendly lady greeted us and, upon hearing my voice, recognized me from my call-ahead. When I mentioned my name, she remarked that it sounded familiar, and that she'd actually - somehow - come across my blog recently and had even recommended that a friend of hers named "Carter" (whose contact I welcome) contact me about gun-related issues! I was happily astounded. I quickly found out that this friendly - and sharp - lady is Linda Zimmerman, the director of the gallery.

Linda spent the better part of three hours talking with me about the purpose of the gallery, the only one of its kind in the world, specializing strictly in high-quality painting and sculpture of the Romantic Realist variety (see Ayn Rand's "Romantic Manifesto" for an in-depth introduction to the genre.) I was deeply impressed at the operation, the selection, and the director. The storefront has had 8 years of profitable operation, but its recent years of online operation alone keep it sufficiently profitable that it can continue in business, without diluting its collection with low-quality pieces which would otherwise meet "school of art" requirements or with technically high-quality pieces which are outside those stated requirements.

The gallery itself has on display about one-third its total collection, the other two-thirds of which is in storage, but pieces of which can be viewed by the seriously interested. The walls are arrayed with paintings, as would be expected, and a number of bronzes are also on display. Linda encourages a healthy, tactile approach to the sculptures: touch them. At one point in our long, animated chat, she took my right hand and placed it on the hip of this statue, "Gratitude" by Danielle Anjou:

This is a lovely piece, and was strangely reminincent of the 1987 Boris Vallejo cover art for the Robert A. Heinlein novel "To Sail Beyond the Sunset," itself a triumphalist riff on Sandro Botticelli's "The Birth of Venus." I love it, probably as much as Monica White loves Bill Mack's alto-relief sculpture "Forever," which was not on display the day I visited... but which I hope Monica can eventually acquire.

Linda and I talked each other's ears off, happily, while Peggy enjoyed one of the overstuffed leather couches near the front of the gallery. We talked about the business of art, and the multifarious ways the gallery has connected Romantic Realist artists, including the recently immigrated Chinese master Han Wu Shen, with deeply appreciative customers, including passionate-but-temporarily-impecunious college students who've arranged payment plans for their "must have" pieces. We talked about a great many other things, with most of the conversation led by Linda cheerily educating me in the business of her gallery, and with me responding with semi-articulate "Wows!" and "Cool!"

I do plan to spend quite a bit more time in the gallery, and may even hold a party of friends there in the near future. Yes, I did say "party"... anyone interested? It would be a great excuse to gather a few dozen of my closest friends and acquaintances in a fantastic setting near the near San Francisco. This is a very real possibility, since Linda did say that the gallery encourages people to hold their parties there. I'm thinking sometime in September, when my good friend Tom Burroughes is in town visiting from London with his girlfriend: first a morning sailing on the Bay (Tom's a qualified yachtsman), then shooting at the range, then a catered affair that night - after cleaning up - at the Quent Cordair Fine Art gallery... sounds like good living to me.

One Maritime Plaza building, San Francisco

Last weekend, walking the very walkable streets of San Francisco with Peggy, I couldn't resist this shot of One Maritime Plaza (formerly known the Alcoa Building):

Yet another reason I keep a very small digital camera in my pocket whenever I leave the house. Hmm... I'm wondering if my good friend and New Yorker Perry Metzger does the same? I'd certainly love to see the occasional building or street shot from New York City on his blog.

"Fighting," by Peter King

On our dojo mailing list today, sometimes-training-buddy (and all around good guy) Irishman Stephen Ewart forwards this excellent essay, "Fighting," written by the U.K's Peter King, a superb Bujinkan practicioner and teacher with whom my friend Monica White has the privilege of training in London. An excerpt:

Hatsumi Sensei criticised martial artists who act like they are dangerous animals. He said that man has been able to use his intelligence to be able to kill dangerous animals in the world. Such people will be defeated – in a way that they had not expected, because they were outwitted by brain and not muscle. When Takamatsu Sensei was in China he was known as the Mongolian Tiger because of his martial prowess. However on his return to Japan, a friend said that he was more like a Japanese cat. Takamatsu Sensei was happy to agree. He said that, in China, it was necessary for him to be fierce like a tiger, but that now that he was back in Japan it was not. He added that women like cats and would often stroke them. Although said in humour, it illustrates the need to be hard only when needed, and then be able to return to gentleness.

Quote of the Day

This is not to say that I believe all religious people are readily capable of murder. Rather, I claim that once you structure your life around ideas that you are not permitted to test, but which you accept as beyond testing (that is, on "faith"), you've abandoned your most important survival tool, namely reason.

Introduce a bad axiom into a mathematical formal system, you can prove anything. Similarly, if you abandon reason for "faith", you lose your only tool with which to distinguish the truth. This could leave you helpless to escape the idea that "God" demands that you kill, and from there it is a short step to shooting abortion doctors or flying planes into skyscrapers.

Incompetent calculator jockeys

I've noticed an interesting phenomenon in my math classes over the last couple of years, which has become more pronounced as the subject matter becomes (to some people) more difficult: the Desperate Calculator Jockey. This is the guy who never studies, is too lazy to do his homework, but somehow manages to struggle his way from one class to the next. He can usually be seen furiously punching formulae into a top-of-the-line TI-89 or its near-equivalent, expecting some magical insight into the problem from the resulting graph. While this approach may actually work in some instances, such as with a simple "differentiate this function" problem, the approach is an utter - and deserved - failure when the student is confronted with the dreaded applications problem (the so-called "word problem.")

Oh, my... this is where thinking skills are really tested, and where numerical prosthesis is nearly worthless. I love these problems: exercises in aircraft fuel vs range optimization, predictions of least-time photon transit through a non-vacuum medium (Snell's Law, an application of the Brachistochrone curve), calculations of marginal cost & maximization of profit, how to make the largest rectangular horse corral with a fixed length of expensive fencing... the good stuff. The Calculator Jockeys rarely know where to start decomposing a problem to its tractable constituents, instead, as usual, attempting to invoke an answer from the aether by keypunch.

I can pretty much tell from looking around a room who's faking it and who's getting it: those who are actually learning the calculus are learning with their pencils, which are constantly moving on paper. The fakers, on the other hand, are constantly pushing buttons. The joke's on the latter group: with the exception of actual symbolic manipulation packages such as Wolfram's Mathematica, hand calculators - to date - depend entirely on methods such as linear approximation. This means that the calculator jockey can actually get the wrong answer for a derivative of a function at a point on a curve, since the curve may not actually be differentiable at that point, but the linear approximation around that point of a secant line connecting points on either side of the original point may exist. Suckers.

Quote of the Day

The concept of luck is also an insult to those who have truly earned what they have. It's an easy way for others to write off hard work and perseverance as merely a kiss on the forehead from the fates.

You see, I find it invariably true that 'luck' strikes those that are well prepared to receive its bounty. By preparedness I mean that they have educated themselves, unerringly pointed themselves in the direction of choice and put themselves forward again and again as a person who desires the chosen end result. I'm as unsurprised by these kinds of people being struck by ‘luck’ as I am by the tallest grounded antenna being struck by lightning.

Hang Ah Team Room, San Francisco Chinatown

I found this place, off the beaten path in San Francisco's Chinatown, on a visit several weeks ago with a friend: Hang Ah Team Room, which apparently has been a feature there since around 1920. The food is fantastic, service is friendly and personal, and the prices are half what I expectecd them to be, an opinion shared elsewhere in this SJ Mercury News article: "Eating Cheap in SF."

Fishing for felines

It just occurred to me now, playing with my cats, that successful cat toys (durability aside) are a lot like the lures of fly fisherman: certain shapes, colors, and noises work better than others... and the lure or toy is simply dead to the fish or cat unless you can play it properly. When you have the action down pat, both fish and cats go bugnutty.

"Diminished Capacity": Perry Metzger has a blog now

My old friend Perry Metzger gave in today and finally started a blog. Now to convince him to add a comment mechanism...

It's an arms race, really

Has anyone else here noticed just how remarkably easy it is to destroy cat toys?

Up to my eyeballs in alligators

In case anyone's wondering, I've been extremely busy this week. Early tomorrow morning, I have a difficult organic chemistry exam. After that, I have some breathing room... email and blog posts to follow.

Quote of the Day

"Feelings" of a supreme being prove nothing since feelings are biochemical states. Feelings no more prove god's existence than seeing pink elephants when withdrawing from alcohol prove theirs. Science demands external evidence that is reproducible. This is how the West has risen from the swamp of mysticism and ignorance to antibiotics, computers, space travel, the internal combustion engine, etc.

Mysticism starts out as an apparently harmless, individual subjective experience. It ends up with a whip in its hand and an explosives belt around its waist, tyrannizing everyone who doesn't share that private experience.

Quote of the Day

I refuse to allow anyone or anything to bring me to my knees. If there is a god I will find a way to free myself of him.

The best mythology I have ever heard on gods is from the Klingons of Star Trek. The Klingons had gods, but they killed them when they realized that they were more trouble than they were worth.

Maybe twitch games *do* help some new shooters

Today's the 60th anniversary of the D-Day invasion of Normandy. I'm reminded that a couple of weeks ago, a couple of friends of mine and I went shooting at a rifle range in northern California, taking a number of weapons including an M1 Garand rifle which probably saw action in WWII. Here, my friend Andy Chen, a brand new shooter (and 18 y/o college classmate), fires my other friend's Garand:

This was Andy's first time out shooting... and on steel reactive targets set out at 100 meters - after having been briefed on safety and weapon operation - he kept up with us two trained, experienced shooters, at least on the sandbag rests. He's spent his high school years reading military history, and knows an incredible amount of factual data on weapons history. He's also used to playing first-person shooter games - in which I've never been interested, thinking them useless for training - causing me to start to re-think my opinions of twitch games.

An older gentleman at an adjacent shooting stall took some time to discuss the Garand with Andy, pointing out that he had ordered his own Garand (which he was also shooting) from the U.S. federal government's Civilian Marksmanship Program, which I've heard about over the years, though I'd bought my own past two Garands from commercial sources.

I'm encouraging Andy to join a local CMP-affiliated club and shoot a match this summer, so that he can be eligible to buy at least a "rack grade" rifle for as low as $350... shipped Fedex directly to his door (yes, they do that)! I don't see Garands selling at gun shows for less than around $800 nowadays. Here's a very detailed and interesting account, with photos, of the experiences of two CMP participants in the purchase and shooting of their own CMP Garands.

It's especially worth noting, for California residents, that a Garand is "Kalifornia legal", making it an excellent rifle to keep locked in the trunk of one's car... just in case. Also note that a number of companies (such as Smith Enterprises) do "tanker conversions" to shorten the overall length, and one can convert the weapon to .308 caliber.

Found on a fortune cookie

Peggy and I just returned from a rather good upscale Chinese restaurant. The paper in my fortune cookie (not Chinese cuisine, by the way) says:

Truth is a torch that gleams through the fog without dispelling it.

Quote of the Day

This is my favorite Atheist quote:

"I contend that we are both atheists. I just believe in one fewer god than you do. When you understand why you dismiss all the other possible gods, you will understand why I dismiss yours."

That sums it up as good as anything, really. Atheism is merely a position regarding the existence of gods-there is no context outside of that. The beliefs we do generally share, we share with every other sane person on earth. And we are less rare than you think - most Atheists don't make their presence known, because there is no reason to. We don't advertise.

Barbara Branden, author of "The Passion of Ayn Rand"

I had the pleasure of first meeting Barbara Branden very briefly at the November 1987 Future of Freedom Conference (FoFCon) in Culver City, California, but didn't engage her in conversation, since she was on her way to a talk at that convention centered around "The Passion of Ayn Rand," her biography of novelist Ayn Rand, with whom she had been associated professionally and personally for a number of decades. Her book had been published the year before, and I'd bought my own copy as soon as it hit the bookstores (this was the pre-Amazon era).

At the end of March this year, a few weeks ago, I finally got the chance to chat with Barbara in a comfortable venue where she was wasn't being shuttled around to talks, in the course of other business: her apartment in southern California. What a lovely, intelligent, funny and benevolent lady she is! I must once again thank my friend Glenn Cripe, who had business to conduct with her that afternoon, for allowing me to tag along with his crew, and of course to Barbara for her warm hospitality... and for autographing that book I bought 18 years ago.

A warm welcome to Yazad Jal

One of the benefits of being myself - being open about my passions and not worrying overmuch about getting along with everyone - is that occasionally, someone I've never heard from introduces himself or herself and extends a hand in friendship, knowing who I am and what I stand for.

This happened again today, this time from somewhere I'd least expected: India, in the form of an articulate fellow named Yazad Jal, a thoroughgoing and studious anarchocapitalist, who'd taken note of me from a couple of running battles I'd been having with a few people on the Atheists community on Orkut.

After taking a quick look at Yazad's Orkut profile, and seeing immediately that he didn't seem like a flake (believe me, I've met a couple of crazies in the last year), I checked out Yazad's blog. I'm impressed: he's a very solid, intelligent, articulate and funny individual who's been writing fairly regularly for a couple of years, and has some interesting things to say about the political and economic problems of India. Visit his blog and make friends. If you're a fellow Orkuteer, introduce yourself to him and make friends there.

Quote of the Day

What he said: Have you ever thought about what Jesus could do for you?

What I said: Not much, really. Religion isn't my thing.

What I was thinking: If your god really is omnipotent and omniscient as your people claim, then he's directly responsible for my mother's stroke and the fact that my sister has been deaf since she was about three. If the Lord, or Jesus, or one of their henchmen ever happens to appeareth before me, I just hope that I remember, among the pyrotechnic light show that should accompany any such apparition, to kick God square in the nuts as a "thank you" for services rendered. [Note: If anybody is offended by this, then remember that God in his omnipotence is entirely responsible for my having said what I've just said - this was all God's will.]
