Oddhead Blog hacked... for the third time

My blog has been hacked yet again. For those keeping track, that’s infection number three. This latest exploit is very similar to the previous one. To humans arriving via browser (e.g., me), the site appears perfectly normal and healthy. Even upon clicking ‘view source’, nothing untoward is revealed. The <title> of my blog is, as always, Oddhead Blog.

However, when Google’s or Bing’s crawlers arrive to index my corner of the web, they see a different <title> altogether — Buy Cheap Cialis Online — and immediately roll their eyes. (Actually even if you run 'curl http://blog.oddhead.com', you’ll see the spam keywords.) The effect of the attack is a kind of reverse cloaking. Cloaking is the black-hat SEO practice of serving legitimate content to crawlers and spam content to people. Here, the spam content is shown to the crawlers and the legitimate content to the people.

Once the crawlers report this appalling information back to their respective mother ships, the search engines have no choice but to delist and demote my blog in their pagerankings. Right now, if you search for or within Oddhead Blog on Google, you’ll see how poorly the bots in Mountain View think of me:

Oddhead Blog hacked again: Spam titles in Google's cache 2012-04-27

You can hardly find any deep links into my blog by searching Google. For example, try searching for Bem+Wom, my invented term for “BEtter Mousetrap, Word of Mouth”. Even try “Bem+Wom oddhead blog”. You”ll find aggregators republishing my content, but no links to the original source, my blog, anywhere in sight. (Note to self: the Bing results for Bem+Wom are awful.)

Once again I am at a loss to understand my attacker’s motivation. Clearly it’s not to sell Cialis to my users, as they remain blissfully ignorant of any changes. The only benefit to anyone is to remove one relatively obscure blog from the search engine rankings and thus to move the attacker one slot up. Having a blog tangentially about gambling probably puts me into a shady neighborhood of the web, yet reverse-cloaking your competition (even if it can be somewhat automated and strike more than one competitor) seems like an awfully indirect way to improve one’s standing in Google. It’s also possible this is an act of pure vandalism.

So what should I do? Although I partly blame WordPress for writing insecure software, I may end up paying WordPress protection money to make this problem go away. I am seriously considering giving up on self hosting and moving my whole operation to worpress.com’s hosted service, where presumably security is tighter, or at least it’s not my responsibility any more. My web hosting service, DreamHost, may also be partly to blame, yet I like the company and have been quite happy with them in many respects. Any advice, dear reader? WordPress.com? Blogger? Try again and hope the fourth time is the charm? Should I be looking to ditch DreamHost as well?

Microsoft Research New York City, First Days

Microsoft Research NYC logo Now that I’ve said my goodbyes, I’m thrilled to announce that I’ve joined Microsoft Research, an organization with going-on twenty-one years of commitment to basic and applied research, employing 850 Ph.D. scientists around the globe including Turing Award winners, Fields Medalists, and many long-time colleagues that I hugely respect. If that were all, I would be over-the-top happy right now.

But that’s not all. Together with fourteen other founding members (seven of whom I can name: Duncan Watts, John Langford, David Rothschild, Sharad Goel, Dan Goldstein, Jake Hofman, and Sid Suri), we are cutting the ribbon on a new outpost for Microsoft Research in New York City. We will report to Jennifer Chayes, the founder and director of Microsoft Research New England in Cambridge, MA. It’s been amazing to watch her up close pursue a goal relentlessly with boundless positive energy. I get the feeling it’s how she approaches everything she does, a realization that played no small part in my decision. The New England Lab, like us, is an interdisciplinary research group that blends computer science, social science, and machine learning, yet from different enough perspectives to make this an almost perfect marriage. It’s no exaggeration to say that helping to found and lead a new research group amid the bursting tech scene in New York City, with the resources of Microsoft behind us, is — as Duncan says — a once-in-a-career opportunity.

The press coverage Thursday was gratifying, including nice pieces in PCMag (source of the sweet logo above), NYTimes.com, AllThingsD, and dozens more. Here is the official press release. For science perspectives, see John Langford’s, Lance Fortnow’s, Dan Goldstein’s, and Jennifer Chayes’s blog posts. One of the coolest moments came when New York Mayor Michael Bloomberg tweeted about us.

Note that, despite the attrition, Yahoo! Labs lives on, probably more applied but not solely so. Ron Brachman, the new head of Yahoo! Labs, is terrific and may be able to do something special there. The Barcelona group remains largely intact and just got 7 (!) papers into SIGIR. Other groups remain intact as well.

The reception within Microsoft research and product orgs has been swift and very warm. The breadth and scope of the place can be daunting at first but invigorating. The ability to impact products that touch hundreds of millions of people’s lives is, as always, a rewarding draw of corporate research. Yet one of the deciding factors for many of us in joining Microsoft is the freedom to interact with universities in research, service, teaching, hosting visitors, hiring interns and postdocs, etc. In addition, we’d like to play our part in the New York City tech scene, including the startup, venture-capitalist, and hack/make communities, plus the new Cornell-Technion campus, contributing to Mayor Bloomberg’s vision of New York City as a tech hub.

An interesting side note that bodes well for my two daughters ages 7 and 4 is that my primary decision boiled down to working for one of two brilliant and accomplished women: Jennifer Chayes at Microsoft, or Corinna Cortes at Google, who is absolutely terrific. Google is a incredible place, a model of efficiency, innovation, and ambition, with an impressive roster of people, and the company is in a very strong position. But this opportunity at Microsoft simply proved to be too good to pass up. I can’t believe how perfectly everything fell into place. I’m beyond thrilled at the outcome and excited to begin this next chapter of my career.

On Thursday April 26, 2012, I resigned from Yahoo! after nearly 10 without actively changing jobs. Here is the full text of the goodbye letter(s) I sent. It’s the kind of long-winded last salvo that few people actually read, and now I’m foisting it upon you, dear reader, but I can’t help myself. Writing it brought back many wonderful memories and a tinge of sadness at the end of a truly amazing work environment for me, but I found the exercise rewarding. I really appreciate the many kind words and well wishes: some were poignant and immensely gratifying. The feeling is mutual. If nothing else, throughout my career I have had the great fortune of working with amazing people who are equal parts brilliant, effective, and nice, including my bosses, peers, reports, and students.

Subject: last Yodle (and last corny Yodle joke)
Date: Wed, 25 Apr 2012 16:44:31 -0400
From: David Pennock

After 8 wonderful years (almost 10 if you include Overture), it is with
very mixed emotions that I leave Yahoo!. My last day is tomorrow,
Thursday April 2526. You can reach me in plenty of ways and I hope you do:

[my email address]
+1-732-XXX-XXXX
Y!IM pennockd | facebook pennockd | twitter pennockd | linkedin
http://dpennock.com | http://blog.oddhead.com

I’ve grown to love this company (purple blood, yada yada) and one of the
deep ironies is that I have a feeling Scott Thompson may actually know
what he is doing and that maybe just maybe Yahoo!’s return to revenue
growth and good public perception will finally come (note I didn’t say
return to profitability — a steady $1 billion in cashmoney profit in
our pocket every year is very far from shabby). I plan to hold on to
some of my stock.

In the early 2000s Google was an amazing Bem+Wom story yet almost no one
(me included) had a clue how they would make money. In 2002, Gary Flake
introduced me to Overture, a company already making hundreds of millions
on search, and suddenly it was clear. I joined Gary in what became
Overture Research and later, under Usama Fayyad’s protective wing, the
inception of “Yahoo! Research Labs”. When Gary left, we hired Prabhakar
and Ron. The rest is history. Andrei, Andrew, Raghu, Ravi, Ricardo,
Preston, Duncan. An absolutely amazing place that was my pleasure to
watch grow and mature. I still remember the excitement of our first
offsite at Half Moon Bay to map out the future of the place.* I remember
a fateful week when Preston, Duncan, and David Reiley simultaneously
gave up their tenure to stay at Yahoo!.

From the beginning Prabhakar saw the importance of including social
science research in the mix for online media. In my little corner, where
we mixed computer science and economics (“algorithmic economics” we
called it), I believe we had enormous effect both internally and
externally. In 2007, Jeff MacKie-Mason, one of our Big Thinker lecturers
and now Dean of the School of Information at the University of Michigan,
wrote (ok, informally to me in email) that our group was “the most
exciting and successful group I’ve seen crossing the CS/Econ boundary”.
If imitation is the sincerest form of flattery, I believe we had a
significant positive impact on the growth in hiring in the social
sciences and in algorithmic economics at both Google and Microsoft. In
our group alone, we published more than 70 papers including at least two
award winners (Arpita just this year). We literally wrote the book
(chapters) on sponsored search and prediction markets. We co-founded the
Ad Auctions Workshop and NYCE Day. People who left often did
fantastically well, including Yiling Chen to Harvard, Mohammad Mahdian
to Google, and Dan Reeves to found his own successful startup Beeminder.
We filed dozens of patents (take that fb!). Former intern Nicolas
Lambert who is now a Stanford professor once told me he hoped to one day
say “it all started at Yahoo!”. I just left a Ph.D. student’s defense
whose three (!) weeks at Yahoo! were good for two chapters in his
thesis. We’ve had academic visitors leave after a week here and follow
up that they wanted to apply for a job — the environment was that great.

Inside Yahoo!, we worked on sponsored search (“squashing” and so much
more by the incomparable Sebastien Lahaie, who we recently discovered is
the central hub of research in New York), display ads, and UGC among
many topics. My passion has been in prediction (markets), and some of my
best memories have been trying to play product manager for a day (or a
couple months) for Predictalot and The Signal. Often it felt more like
operating a startup but with incredible advantages in resources, people,
and of course access to that monster traffic firehose. This was Yahoo!
at it’s best — marshaling talent from all over the globe in many
divisions and specialties to produce a product that no one had ever seen
before, and that no one including us even knew would work. One of the
saddest parts of departing now is leaving The Signal behind, an
incredible effort and in many ways our biggest and best, led by David
“force-of-nature” Rothschild and so many people behind it. Sadly, some
were let go and others are leaving on the own accord, and we’ll never
know what could have been in a counterfactual universe. Yet I believe
The Signal will live on in the good hands of those who remain, including
Chris Wilson, Alex, Ingemar, and the absolutely phenomenal Bangalore team.

By far the best part of working at Yahoo! was the people. It’s been my
pleasure to work with so many fantastic colleagues in Labs and
throughout the company. In the recent turmoil many in Labs have been, as
Preston said, “evaluated by the market”, and came out looking pretty
darn good, with calls, interviews, and offers from the best companies
(Facebook, Google, Microsoft) and universities. Early on we set a goal
to always hire above the mean, and I truly believe we did that. (Having
been here from the beginning, you can see where that leaves me in this
incredible crowd.) It’s a cliche but a true one: I am only as good as
the people working with me, and I’ve truly been blessed with amazing
colleagues, bosses, employees, postdocs, and interns. To Sebastien,
Arpita, Giro, and David Rothschild, plus Mridul, Navneet, Sudar, Arun,
Shrikant, Kim, Chris, Janet, Ron, Michael and dozens more and everyone
who has come before, from Preston & Prabhakar on down, I can’t thank you
enough and I owe you almost everything.

Goodbye for now,
Dave

* For history buffs, these were the people at the initial Yahoo!
Research offsite: Prabhakar Raghavan, Dennis DeCoste, David Pennock,
Omid Madani, Shyam Kapur, Andrew Tomkins, Winton Davies, Ravi Kumar,
Bernard Mangold, Ron Brachman, Marc Davis, Michael Mahoney, Kevin Lang,
Seung-Taek Park, and Dan Fain.

** I also remember the first few days of Yahoo! Research New York in
2005, with just Ron, John, and I. It’s amazing to see what we have
become since.

*** An even more arcane note of history: the Overture control room made
a cameo as NASA Mission Control in James Cameron’s 2003 movie Ghosts of
the Abyss. I am on somewhere on the cutting room floor trying to muster
that awestruck look one gets upon seeing alien life for the first time.

From: David Pennock

I’ll abuse my final act of spam to add one more thing. For those of you
remaining, you’re in good hands with Ron. I believe he can do something
special with Labs. In case you’re not familiar with his background, Ron
is frighteningly smart (Princeton undergrad, Harvard Ph.D.), was a
pioneer in artificial intelligence, wrote a seminal book on Knowledge
Representation, served as President of AAAI, the main AI society, ran
research groups at Bell Labs & AT&T, and is a highly organized, fair,
diligent manager who listens actively, gets things done, and, in
addition is a genuinely nice person. Best of luck to everyone.

A professional thanks and a personal goodbye to Steve Jobs

10 Print "Hello"

That line typed on an Apple II computer in my Dad’s office in the fourth grade got me hooked on computer programming, an addiction I never outgrew.

Over the years, I’ve had the pleasure of owning, using, or programming on many of Steve Jobs’s creations, including Apple II+, Macintosh IIcx, Power Mac 7100, Newton, NeXT, Powerbook, Macbook Pro, and iPhone. I’ve been a consistent Mac in the Mac-vs-PC battle since 1984 (though I admit to a brief affair in 1998: it didn’t mean anything, Steve, I swear!). Jobs himself ignited an us-versus-them fire, which smolders on today in Apple’s John Hodgman-as-PC ads, back in 1985 with one of his best quotes:

Playboy: Are you saying that the people who made PCjr don’t have … pride in [their] product?

[Jobs:] “If they did, they wouldn’t have made the PCjr.” [Playboy, Feb. 1, 1985]

Around that time, my friends and I had a running joke: “I got a PCjr,” one of us would say; “you’re going straight to hell, kid,” the other would shoot back.

Buried treasure: Old Apple II and Power Macintosh computers, waiting to be dusted off… someday

My wife and kids (ages 7 and 4) are more recent converts, owning a Duo, an iPhone, an iPad, and two iPod Touches among them.

I’ve owned Apple stock since about 1997, my single best investment, increasing 4,460 percent. (Priceline is my second best, gaining 3,990%.)

Like Lance, I’ll never forget where I was when I learned that Steve Jobs had died. Steven Colbert told me. Live. After a hilarious taping of the Colbert Report and four performances by the artist formerly known as Mos Def (apparently a perfectionist: who knew?), Colbert ended by balancing his iPhone on his desk, letting it fall over, then telling us, “Steve Jobs died. Sorry to be the one to tell you.” To say the mood of the audience changed instantly would be an understatement. Smiling faces turned down. Cries of anguish and “oh no!” rang out from nearly everyone in the audience, a mark of how Jobs’s influence and name recognition has grown from tech hero to global cultural icon. (Colbert gave Jobs a proper tribute the next day.)

There’s a thread in our office about the extent to which perceived success or failure at the CEO level is a fooled-by-randomness trick of the mind. But there are some examples where even the strongest skeptic must admit that an organization’s success is almost surely owed to the exceptional greatness of a single individual. Warren Buffet and Coach K come to (my) mind. But Steve Jobs must be the prime example. As if ushering in the era of personal computing and computer-animated movies was not enough, Jobs continued to outdo himself year after year, with iPod, iTunes, iPhone, and, barely a year ago, iPad. Sadly, or maybe purposefully, Jobs seemed to hit his stride just as he died. As a long-time disciple of Jobs, I’m amazed at the amount of focus in his obituaries spent on gadgets he created in the last ten years.

Jobs famously advised not to spend too much time celebrating success.

I think if you do something and it turns out pretty good, then you should go do something else wonderful, not dwell on it for too long. Just figure out what’s next.
—NBC Nightly News, 2006

Those were not empty words for Jobs: it’s how he lived his own life and how he squeezed so much out of the 56 short years he was given. The early storyline of Apple pegged Steve Wozniak as the brains and Jobs as the lucky business-minded sidekick. It turns out that Jobs was way more exceptional than the 1990s nerderati — who like me relate more to Woz — gave him credit for. Jobs had the brains, the vision, and the charisma in a combination so rare I’m not the only one who can’t think of another human alive who compares. To get a taste, read or watch Jobs’s Stanford commencement speech: it’s truly brilliant, inspiring, and one of the best ways you can spend the next few minutes of your time.

To the ultimate hacker painter, the first last analog, the nerdiest salesman, the studliest genius, the most productive perfectionist, the most detail-oriented visionary, and a personal hero:

A professional goodbye and a personal thanks to Carol Bartz

commentary, computer science, people, personal, technology, yahoo 4 Responses »

Oct 072011

My geek CEO was fired. If you’re wondering whether she deserved it, or Yahoo! is better off for it, or Roy Bostock is a doofus or dorfus, I don’t really know.* But I do have a personal story about Carol Bartz that’s indicative of the kind of CEO she was and the kind of person she is, perfect for Ada Lovelace day, a day to blog about women in science and technology who inspire you.

In May 2010, my wife Lauren was diagnosed with breast cancer. On Sunday, May 9, 2010—Mother’s Day no less—I received a phone call. “Hello?,” I said. “Hi, this is Carol Bartz,” she said. “Wow!,” I couldn’t help saying. I had never spoken to her before. She proceeded to say how sorry she was for me and Lauren, to reassure us, to ask me questions, and to answer mine.

More than a year, multiple surgeries, and six chemo sessions later, I’m happy to say that Lauren is past the worst part of the treatment and, to the best of anyone’s knowledge, cancer free. At the time, we were frightened, bewildered, and angry. To me, the most overwhelming feeling was disbelief. Was this really happening to us? It was surreal. Lauren’s strength and sheer will to keep our home life as normal as possible, and her ability to turn the ordeal into a positive is amazing and helped me cope. That my mom and Lauren’s mom went through the same thing also helped. The more we looked into it the more we realized breast cancer was everywhere—shockingly common even at Lauren’s age. (Especially in New Jersey, one of only five states in the top tier for both incidence of and mortality from breast cancer.) The calls to increase the age of first mammogram border on criminal. One silver lining for Lauren has been meeting the amazing support community of breast cancer sufferers, survivors, and their friends. They have inspired her to give back in many ways. My mom, a radiologist and ACR fellow, was herself inspired to specialize in mammography and pursue breast cancer research.

It turns out, Carol Bartz is a survivor herself and, in addition to being one of the fifty most powerful women in business, is just another member of the breast cancer support community who cares deeply. Carol had over twelve thousand employees. To take the time to call one of them on a holiday weekend to address personal problems and pain shows the kind of leader she is. (And shows the kind of bosses Preston and Prabhakar are, who thought enough to bring it to her attention.) It’s a “Yahoo! moment” and a Carol moment that I remember vividly and continues to stick out in my mind. I suspect most stereotypes of corporate and public leaders as conniving powermad ladder climbers are just that: stereotypes. But still, I’m convinced that not all—probably few—CEOs would do what Carol Bartz did. Goodbye, good luck, and, most of all: Thanks, Carol.

* I will say that I respect Carol’s willingness give her blunt assessment of the board, possibly risking $10 million to do so, and to come right out and say “I was fired” rather than hide behind “more time with family” cliches. I’m not surprised that the board gave their full confidence to her in public just two months before firing her—of course a board always has to say that they have confidence in their current CEO. I am surprised and dismayed that, at least judging by her reaction, it seems the board was also giving their confidence to her in private. That’s HR 101: No one who’s fired should be surprised.

On Intrade CEO John Delaney's death

commentary, people, personal, prediction markets 10 Responses »

Aug 012011

A few words on the tragic death last May of John Delaney, the founder and CEO of prediction market company Intrade. John died near the peak of Mount Everest, climbing toward one of his life’s dreams and leaving behind a wife and three children, including one born only days before he died that he never met.

John founded Tradesports, a pre-cursor to Intrade, in 2000. Eventually, the non-sports contracts on Tradesports where spun off as Intrade, and Tradesports was shut down in 2008, in hopes of obtaining U.S. regulatory approval. I remember marveling at the technology, featuring ajax-ian magic like push updates — new bids appeared and filled bids disappeared live in a flash of color — well before its time, before we even knew what to call it.

The prediction market community embraced John, and John them. John was happy to take academics’ quixotic market ideas — like combinatorial markets, decision markets, merger markets, tax markets, or search engine markets — and float them on Tradesports or Intrade, and share back data for academic studies. I remember when we learned a Director at Intrade would speak at the first Prediction Markets Summit in 2005, we were thrilled to hear from a pioneer and innovator: one of the “big guns”. Chris Hibbert asked, “isn’t Tradesports the largest prediction market in the world?” It was hard to say: in a way, yes, it was and still is the largest market widely identified with the adjective ‘prediction’, but of course it depends how you define it: does Betfair count? Vegas? Stock options? If I recall, John himself spoke remotely at the second PM summit in New York.

Intrade became the prototypical example of a prediction market, mentioned in almost every academic paper on the subject. In 2008, Betfair, a goliath to Intrade’s David in terms of revenue and profit, got so annoyed they lashed out and sent the following attack on Intrade and defense of their own service dubbed Betfair Predicts (now shuttered):

InTrade’s election charts are republished frequently—despite continuing
problems with market manipulation.

Betfair is the world’s largest commercial prediction market with $33
Billion per year flowing through its exchange and is well known for
integrity and advanced technology…

I don’t believe I met John in person, but he and I emailed a bit, and beyond being whip smart and a fantastic entrepreneur, John was simply an incredibly nice guy. He kept repeating, at the end of nearly every email, that I must come to London so we could meet and have a beer. Talking to others, it seems I am far from alone in this standing offer from John. On the original prediction market mailing list, John Delaney was always the peacemaker: always diplomatic and rising about some surprisingly testy exchanges. He always spoke to raise the prominence of the field as a whole, ahead of his own interests with Intrade, not only believing but acting on his belief that “a rising tide lifts all boats”.

John didn’t seem like the type to seek out risk for the simple thrill of it; rather, he took calculated risks in business and life to progress. His success at work and at home attest to this. In hindsight, it’s easy to say he calculated wrong in attempting to climb Everest, but especially among prediction market proponents we know that decisions cannot be evaluated in hindsight. Decisions must be judged based on the information available at the time the decision is made. My guess is that John knew the risks and felt the climb was a gamble worth taking in an effort to achieve a long-standing goal and to accomplish a feat few others on the planet can claim.

John, you will be sorely missed, but your legacy lives on at Intrade, in the prediction market community, among your family and friends, and in the business world, sadly and suddenly now missing one of it’s great entrepreneurs with a spirit of adventure.

Famous for 15 tweets

Jul 292010

TV era: $quote = “In the future, everyone will be world-famous for 15 minutes”;
Search era: $quote =~ s/minutes/links/;
Social era: $quote =~ s/links/tweets/;

This month I’ve had five times more traffic than in any other month since I began blogging in Oct 2006, even during woblomo.

Why? I paid Paul Graham a compliment that struck a minor viral nerve, spreading through twitter, facebook, and blogs and sending over six thousand people my way on July 16 alone according to quantcast. Of course most have since dispersed.

Power on the web flows backward through referrals to the sites that people begin their day with, the sources of traffic. Referrals from social media, unpredictable and bursty though they may be, are inexorably on the rise. As they grow, power will shift away from search engines, today’s referral kings. Who knows, this may embolden publishers to take previously unthinkable steps like voluntary delisting, further eroding the value of search. This has all been said before, perhaps best by Mark Cuban starting in 2008. It would be a blow to openness and hurt users, but would spark a fascinating battle.

Another meta note: I installed a new WordPress theme: Suffusion. It’s fantastic: endlessly configurable, bug free, fast, and well designed. I happened upon it by accident when WP 3.0 broke my old theme and I couldn’t be happier. Apparently written by a teenager, I donated to his beer, er, coffee fund.

World Blogging Year

challenges, economics, fun, oddhead blog, woblomo 3 Responses »

Apr 012010

First: I did it! A perfect 16 out of 31. I completed the (ok, my) World Blogging Month challenge to blog every odd day in the month of March.

Last year WoBloMo leapt out of the gates with five participants but I fell five hours short of the goal. As far as I know only Anthony and I returned for year two. He succeeded too according to official Australian Rules.

Again, I found the exercise worthwhile, clearing a number of items out of my queue, albeit mostly the easy and inane ones (c.f. the barking), and boosting readership.

In fact, I enjoyed it so much that I’ve signed up for World Blogging Year (WoBloYe). I will blog every odd day of every month at least through the end of 2010, starting today.

In fact I have formally pledged to stickk to my goal. Moreover, I am putting my money where my mouth is, PM-style. For every odd day of the month that passes blog-post-free I will donate $100 to my anticharity, the re-election fund for Don McLeroy. If I miss two deadlines in a row, my antidonation will double. Three missed deadlines in a row and it will quadruple, etc.

I’ve enlisted kibotzer’s help and you can follow my progress there. Wish me luck!

Update 2010/04/02: April Fools!

P.S. In all seriousness, read that New York Times article about Don McLeroy. It’s one of the scariest articles I’ve read in a long time. It’s about how ultra conservatives on the Texas board of education are rewriting history and science according to biblical and republican dogma, and how standards in that enormous state can dictate what gets printed in textbooks nationwide. They’ve done things like add Newt Gingrich and delete Edward Kennedy as significant Americans. They’ve banned classic children’s books by Bill Martin Jr. because they confused him with a different Bill Martin, author of “Ethical Marxism”.

It is the most crazy-making thing to sit there and watch a dentist and an insurance salesman rewrite curriculum standards in science and history. Last year, Don McLeroy believed he was smarter than the National Academy of Sciences, and he now believes he’s smarter than professors of American history.

Meet my maker, or Bernie Pennock and the blowtorch fountain

My dad is an original maker. When I didn’t want to pay $200 to replace a broken car key housing, he sent me this vice made out of quarters he fashioned and all the parts I needed to attach it to the key.

Aa biomedical engineer, he led a study showing that a non-invasive mask can save people from respiratory failure as well as intubation. The technique is now common practice and, fittingly, the device helped saved his own life several years ago. He also invented a piezoelectric band to measure heart rate and breathing during sleep more comfortably than electrodes.

He did his Ph.D. dissertation on, in a sense, protien folding, in the days when cut and paste meant scissors and glue. I have an original copy of his dissertation and it’s a beautiful object to behold.

And what about that blowtorch fountain?

Read about it in this profile of my dad by Maureen Simpson highlighting both his hacker and painter sides.

In his retirement, Bernie Pennock found a way to turn fire into water.
The former medical research scientist said it was just one of the many problems that needed solving in his home, where art has become the answer.
“It’s really the same idea as what I did as a career,” Pennock said of his hobby. “You see a problem and think of how to solve it. I think of what I want to do and how to do it, and then I do it and see if it works.”
Using old brass blowtorches he has collected over the years from antique shops and friends, Pennock constructed a fountain next to the pathway leading up to his front door…
Instead of spitting flames, Pennock’s structure spouts water. He mounted the old-fashioned tools to a sheet of copper and then rigged a water pump and pipes behind it… Pennock said his friends describe the work of art as “very Rube Goldberg.”…
Inside his home — on lampshades, along walls and attached to windows — guests can see numerous examples of the former scientist’s artistic experiments. His most recent obsession, apart from the fountain, has been working with stained glass.
“It all started with this window that looks out on the pool,” Pennock said. “I wanted something that let in light, but wouldn’t allow you to see into the bathroom. When I got an estimate to find out how much it would cost to have someone do a stained glass window, I decided to make my own.”
The multi colored scene is based on a photograph Pennock took of two people walking on the beach. Since then, he has made at least a dozen more windows that include a copy of a Monet painting, the Talmadge Bridge in Savannah and his interpretation of
12 stained glass windows designed by Marc Chagall at the synagogue of the Hadassah-Hebrew University Medical Center in Jerusalem, Israel.
Pennock said he usually buys the windows from a Habitat for Humanity store and gets his stained glass from a supplier in Charleston. The next project he plans to take on is a bamboo sculpture, because he’s running out of windows.
“I dabble in a lot of things,” Pennock said. “I like to invent. I just start from scratch, get ideas and see what happens.”
Among his rules for living, which Pennock painted on leftover floor tiles that hang next to the blowtorch fountain, is fittingly: “Pay attention.”

Oh, my brother and sister are makers too. And my mom a trailblazer. I’ll leave those for another day.

Prediction market news: HSX, Nadex, Predictalot, mailing lists, & EC'10

Some prediction market related news:

The Hollywood Stock Exchange is the latest example of life imitating art imitating life. The venerable HSX, the second oldest play-money prediction market (and oldest that anyone has actually heard of) is getting real. You’ll soon be able bet real money on box office returns and deposit your winnings in First Life. The move has been a long time coming — Cantor Fitzgerald purchased HSX in 2001 with the explicit goal of converting it into a real-money exchange — but Cantor was decimated in the September 11 WTC attacks, and the road to regulatory approval has been slow. The real HSX will of course say goodbye to the virtual specialist and the opening weekend adjust, two facets of the game that make it fun to play, but that create significant amounts of (virtual) wealth out of thin air. The Cantor Gaming group is engaged in other interesting initiatives. They are taking over a sportsbook in Las Vegas and turning it into more of a derivatives exchange with live in-game betting, a step toward my dream of a geek-friendly casino. Interestingly, another company called Veriana Networks is close to launching a competing Hollywood derivatives market called the Trend Exchange.
I’ve recently seen ads in the elevator in my building for Nadex, the new incarnation of HedgeStreet that was acquired, redesigned, and rebranded as the North American Derivatives Exchange. I haven’t checked in on the market since the rebranding — in fact I can’t remember if my HedgeStreet account transfered over. I wonder how widespread their ad campaign is and how Nadex is doing?
Predictalot update: 50,000 people have logged in and 11,000 have made at least one prediction.* They’ve made 91,000 total predictions of 5,500 different kinds. We’ve been written up in NYTimes, VentureBeat, L’Atelier (“C’est ce que fait Yahoo!, avec Predictalot.”), and Wired. People are saying everything from “wicked fun”, “great idea”, and “love the game” to “disaster”. Either way, people care. It’s been a ton of fun and its popularity has wildly surpassed my expectations. The final four is this weekend. Then not much time to get in as many improvements as we can before the World Cup.
If you’re not aware, there is a new prediction market mailing list that strives to be open, transparent, objective, and independent under some simple ground rules. I encourage you to join it. I abandoned the old PM list owned by John Maloney for a number of reasons. The old list clearly operates in a payola style — sponsors of Maloney’s events receive prominent billing. That might be ok, except Maloney bills his list and his events as open, non-profit affairs, yet he charges quite a bit and is evasive about financial details (actually he says he doesn’t keep records). Over the years, Maloney has asked me/Yahoo! to sponsor his events several times, occasionally berating me when the answer is no. He’s made some questionable wikipedia edits to highlight his group. Still, I’ve gone to some of his events and find that very good people go there and give interesting talks, and Maloney is very reasonable and personable face to face. My final straw came when Maloney censored me on his list for criticizing him, admittedly in a snarky way.** So I joined with Emile, Bo, Forrest, Justin, Jed, Adam, and others to start afresh.
The 2010 ACM Conference on Electronic Commerce to be held June 7-11 at Harvard features at least six papers on prediction markets:
- L. Jian and R. Sami, Aggregation and Manipulation in Prediction Markets: Effects of Trading Mechanism and Information Distribution
- K. Iyer, R. Johari and C. Moallemi, Information Aggregation in Smooth Markets
- A. Othman, D. Pennock, D. Reeves and T. Sandholm, A Practical Liquidity-Sensitive Automated Market Maker
- S. Goel, D. Reeves, D. Watts and D. Pennock, Prediction Without Markets
- A. Othman and T. Sandholm, Automated Market-Making in the Large: The Gates Hillman Prediction Market
- Y. Chen and J. Wortman Vaughan, A New Understanding of Prediction Markets Via No-Regret Learning

* I believe one in five logged in users placing a prediction is actually a high conversion rate for a prediction market and a testament to our user interface design. Mike Speiser told me that Bix had a tough time converting their users — who loved to vote — into traders in their American Idol prediction market, one reason why they abandoned the experiment.
** The exchange went like this: Maloney’s assistant Jennifer Hewitt announced that “Crowdcast, the leading provider of prediction market solutions for collective forecasting” was joining Maloney’s latest event. Emile asked “leading… Based on what metric, exactly?”. Then I quipped “leading recent contributor to John Maloney”, which Maloney censored. In Maloney’s defense, the “leading provider” language actually came from Crowdcast’s own website (their meta description tag) and so it appears in the snippet when you search for “crowdcast” in Google.
