Lessons from my garage door remote

It's possible to be too geeky.

When the remote for our 1996 Sears Craftsman garage door opener failed I naturally entered the remote part number into Google. This led me to a forest of aftermarket "universal" remotes; after a few hours of research and with some trepidation I placed my order. The remote I got was three times the size of the old one, but it works quite well.

Today I decided our keypad needed to be replaced. Once again I started digging through Google and Amazon, but this time I happened to notice a "call 800-... for parts" notice on the opener.

It seemed unlikely, but a search on Craftsman parts led to the Sears Parts Store. There a search on the opener part number led through two menu options to a list of compatible accessories. The sites not perfect, as the part numbers have only a vague one line description. I ended up going to sears.com, searching on the part numbers, and ordering two devices. Not cheap, but I'm reasonably sure they'll work.

As an experiment I tried constraining my search by "sears.com" and googling on the part number. This time the search worked.

There are two lessons I draw from this:

1. There's still a "deep web" of database tables Google can't track -- that's why starting with the parts site worked.
2. Sears.com is ranked relatively poorly by Google, so it didn't show up in my searches. I have to remember to scope by site more frequently.
3. I might have done best of all to phone the Craftsman parts number on the side of the opener, but, really, that's unthinkable.
   

Update 8/19/07: I have a few clues as to why Sears may rank pretty low in Google searches:

1. Despite my usual practice of turning off all opt-in spam invitations, Sears still sent spam to my email address (of course I only gave them my spam account, but still!)
2. Their stated returns policy requires a shipping statement as well as a receipt?

This weekend, a virtual world teeters on the edge

The virtual world of finance, that is. The world where imaginary trillions flit about like moths in a storm ...

Grasping Reality with Both Hands: Brad DeLong's Semi-Daily Journal

...today the monetary base in the North Atlantic economies is 7% higher than it was yesterday--an annualized growth rate of 2100% per year"...

This is when we find out how good our emergent financial systems really are. The S&P has wiped out the gains of the past four months, but that's really not so bad. If we're above the 12 month low next weekend we'll be doing fine.

Dockables: donation ware, clever!

I think TUAW pointed me to Dockables. These are donation ware applescripts with a full installer and excellent icons. I have "sleep", "screen saver", "screen capture", and "log off" in my Dock now. Since I don't use my Dock for much these are great to have, and of course LaunchBar (love it) can activate any of them easily.

I've always had trouble remembering the key combination for screen captures, and I don't like the TIFF format Grab uses (though I'm sure there's a way to change Grab to use PNG, I don't like those tweaks if I can avoid them). Now I use dockables, open the PNG in Preview, select, copy and then either pastse into a document or "create new from clipboard", then save with a useful name or paste. Ok, so it's not ultra efficient, but it works rather quickly.

These are also handy for the docks of my family members, who really don't know any key shortcuts or hot corner mouse actions.

NTY Business: replaying press releases?

"Jeff Leeds" wrote this for the NYT:

Universal Music Will Sell Songs Without Copy Protection - New York Times:

... the music will not be offered D.R.M.-free through Apple’s iTunes, the leading music service. The use of copy protection software has become a major bone of contention in the digital music business, where iTunes accounts for the vast majority of download sales. The record labels generally have required that retailers place electronic locks to limit copying of music files. But Apple’s proprietary D.R.M. does not work with most rivals’ devices or software — meaning that music sold by competing services cannot play on Apple’s popular iPod. Some record executives say they believe that the stalemate has capped the growth of digital music sales, which the industry is relying on more heavily as sales of plastic CDs slide...

Apple sells music with DRM and without DRM. Universal's refusal to sell through iTunes has no logical connection to Apple's DRM, though it may make business sense as a way to weaken Apple's dominant retail position and keep competitive channels open. A reasonably informed human being would have noticed that that Universal's press release made no sense, so "Jeff Leeds" must be an algorithm for repackaging press releases. (Either that or a very dim editor chopped some key sentences out of the article.)

Pollution has vitamins

Scott Adams sums up the GOP candidates in 3 panels

... terrorists will use your skulls for salad bowls ...
... take money from the people who don't vote for me and give it to the people who do ...
... pollution has vitamins ...

Ok, so the 2nd is somewhat bipartisan, though when I vote Dem I'm voting for less money for me (at least directly and in the near term).

I don't recall Scott Adams getting political before. Perhaps the GOP presidential slate is inducing an unprecedented sense of national terror among the few Americans still conscious. There may not be anything worse than Cheney, but the leading troika are arguably worse than than Bush, who's already among the worst Presidents in American history. Really, Romney, Giuliani et al are exhibit A for terminating the GOP and starting over.

Dying heroically - known for his coffee mugs

Dead heroes rarely receive the attention of heroes who live to tell their tales. This is the first I've read of a hero of a local disaster who died trying to save others.

State to get funds; death toll reaches 8

... The medical examiner also reported Friday that Peter Hausmann, 47, a father of four from Rosemount who survived the bridge collapse and escaped from his van only to perish while apparently trying to help others, died of drowning...

One might wish Peter, father of four, had been less heroic, but he was. MPR has a small article about him. I'd have titled this post "A geek dies heroically" but I can't know if Peter would have approved:

Peter Hausmann, 47, was a computer security specialist worked at Assurity River Group in St. Paul. The company's president says Hausmann was a quiet leader and a man of faith.

There's one in every office. The guy who's the diligent worker, nose to the grindstone. The one who mentors colleagues and whom everyone trusts. And the guy who's the first to make the coffee every morning...

..."One of the things that was very high on the priority list was to get the coffee machine in and running as fast as possible," says Olejnik. "Pete was very happy when we got that installed. He was the number one person who was going to be using it."

Olejnik says Hausmann often logged long hours at the company's small office of eight employees, sticking around until 6 or 7 p.m. Hausmann was, Olejnik says, a quiet leader, a devoted Catholic, and a man capable of explaining the most confounding aspects of information security....

...Hausmann resided in Rosemount, hailing originally from South Dakota. He spent time in Kenya, where, Olejnik says, he worked as a math and science teacher. Kenya is also where Hausmann met his wife, Helen.

The family has declined requests for interviews. They told a newspaper last week that the night of the bridge collapse, Hausmann was heading to St. Louis Park to pick up a friend for dinner when the bridge gave way.

He reportedly phoned his wife during rush hour traffic on the bridge and was not heard from again. His car has since been pulled from the Mississippi River...

...When that difficult time comes, says, they'll give the Hausmann family any of Peter's personal effects, including the cluster of coffee mugs sitting empty at his desk.

I wonder how well his co-workers knew him, and whether they'd have marked him for the heroic mold. Peter, I salute you. If I find a fund to help Peter's children's education (four) I'll post on it.

Update 8/12/07: See the comment below from a niece of Peter's.

Update 8/14/07: Family fund (taken from comments). I've sent my contribution on its way.

... My cousins ages are 16, 14, 10, and 7 and I can assure you that they have very promising futures. Their father has left them with an unquenchable thirst for knowledge. Thank you once again for your interest in my family. I told my mother, Pete's sister, about Pete being called "a geek who died heroically" and for the first time in almost two weeks I saw her laugh. Thank you, thank you, thank you. Anyone that would like to donate to the the memorial fund can send the donation to:

Dear Salon and Dear Volkswagen: this will cost you

This is how my Salon Premium article looks today when viewed with Firefox:



An extremely obnoxious VW ad is covering a chunk of the article. VW, I am very annoyed. You are on my poop list.

Salon, one more time and I drop the Premium subscription.

I am not amused.

Should we preferentially tax premium gasoline? How evil would that be?

What fraction of premium gasoline sales are an evil exploitation of the weak minded?

Here's why the question matters. Most rationalists believe we need a carbon tax to keep our planet's climate within a familiar range, and we know we have a $1.5 trillion dollar infrastructure bill coming due just as we boomers prepare to suck the young dry. So most rationalists would say a carbon tax now, starting with a gasoline tax increase, makes scientific, political and economic sense. On the other hand, many rationalists, due to ethical impulse, a desire to survive, or an aesthetic aversion to starving masses, prefer to avoid exploiting the weak and gullible. If we add up a carbon/gasoline tax, infrastructure repair, and the duty/wisdom of the strong aiding the weak, should we preferentially tax premium gasoline?

The answer depends in part on what percentage of premium gasoline sales are a scam perpetuated on the weak minded:

Fact or Fiction?: Premium Gasoline Delivers Premium Benefits to Your Car: Scientific American

....Most modern cars, however, are designed to employ a specific compression ratio, a measure of how much room is available to the fuel when the piston is at the bottom and the top of the cylinder. This compression ratio—somewhere in the neighborhood of eight to one—tolerates lower octane fuels (such as regular gasoline, good old 87 octane) without knocking. "The compression ratio is fixed by the designer of the engine," Green says. "The regular fuel will burn properly and the premium fuel will burn properly and therefore there is no reason you should pay the extra money." High-performance engines, such as those in some sports cars or older, heavier automobiles, often boast much higher compression ratios. These cars—for example, Shepherd's Subaru WRX—require premium gasoline and will definitely knock without it. "I have to put the 92 octane in," he says. "It has a turbocharger."...

...for standard cars on the road today, purchasing premium gasoline is simply paying a premium for a fuel that delivers no added benefits. "If you think you need it," Green says, "you're being very eccentric.

So collector cars and sports cars (and lawn mowers? motor cycles?) need premium gasoline. These are not requirements for modern economic survival -- they are luxury items. That would favor a preferential gasoline tax on premium gas. On the other hand, we know a significant fraction of premium gas sales are an exploitation of the naive, the gullible, and the weak. That seems to argue against a preferential tax -- but in fact I think it supports a preferential tax. I bet that within days of announcing such a tax, the vast majority of consumers who don't need premium gas will learn that they've been conned, and they'll stop using it. So a preferential tax won't raise all that much money (we have to tax all gasoline), but it will serve a social good anyway. It's worth doing.

Incidentally, there's another question I haven't asked. Would we be wiser to equip our cars with floatation devices and spend our carbon tax money on avoiding war with China, solar energy research, "rationalizing" the tax code, meteor impact prevention, biowar prophylaxis or any of a hundred other worthy causes? Ahh, well, I'll save that one for another day.

Rome burns. Bush fiddles.

We have a 1.5 trillion dollar infrastructure bill to pay.

MPR: Bush cool to federal gas tax increase

Just one week after the deadly I-35W bridge collapse in Minneapolis, President Bush reacted coolly to a plan to raise the federal gas tax.

President Bush said Congress should reprioritize the way it spends highway money instead of raising taxes to pay for future bridge repair.

"Before we raise taxes, which could affect economic growth, I would strongly urge the Congress to examine how they set priorities," said Bush. "If bridges are a priority, let's make sure that we set that priority before we raise taxes."

Bush made the comments one day after Rep. Jim Oberstar, DFL-Minn., announced a plan to increase the federal gas tax from 18 to 23 cents a gallon.

Oberstar, who chairs the House Transportation Committee, says the money would go into a new trust fund for repairing and replacing bridges. He said the plan would raise about $25 billion over three years....

Cut out GOP senator Stevens bridge to nowhere and a few similar boondoggles, and you get maybe $3 billion. We don't need $3 billion. Bush is an idiot.

On the other hand, assume we need to raise $2 trillion over 25 years (cost plus interest), so we need an extra $80 billion a year for the next 25 years. That's more like a 15 cents a gallon price rise in the gas tax. So three times what Oberstar is saying now, but, still, he's at least on the right track.

[rewritten, because I was too sleepy to remember we don't need to raise all the money all at once.]


I think we're going to lose at least a dozen major bridges before we get real.

Ignatieff: I'm so glad I didn't bother ...

Michael Ignatieff, a pseudo-Canadian who emerged from Harvard to bring salvation to the barbarian backwaters of my birthplace, wrote an OpEd article for the NYT a week ago. I tried to read it, but I fell asleep half-way through. It was ponderous, pompous, vacuous, internally inconsistent insofar as it had any meaning, and, by the way, it made no sense. I vaguely wondered about commenting on it, but I don't have the skill to make that kind of commentary funny and I couldn't think of anything useful to say. (Other than, Oh Canada, you don't deserve this.).

Happily, others have done the job. Crooked Timber's "Ignatieff" has some good links and droll commentary, but the first comment links to ...

David Rees: Cormac Ignatieff's "The Road" - Politics on The Huffington Post

Hello everyone! Personal message to all the New Yorkers out there: Did you read Michael Ignatieff's essay in the the NY Times Magazine? If so, contact me ASAP to let me know you're OK. I put your flyer up at Grand Central Station, but have heard no response.

Myself, I'm just making my way out of the debilitating Level-Five Mind Fog that came from reading the thing. Even my "Second Life avatar" has a headache! (Hey young people, did I get that right? Hope so! See you in "Warcraft Worlds!")

The essay is called "Getting Iraq Wrong." And baby, if Michael Ignatieff got Iraq wrong, I don't want him to be right! Because this essay can MAKE LEMONADE IN YOUR MIND...

And so it goes.

Again, we ask, "where is the medium lobster", and what happened to him in July 2006?

The Apple iMovie story: An interesting lesson in modern software evolution

Apple's iMovie was a very good product for editing home videos. Apple decided, however, that they needed to provide a simpler product for managing small video fragments (phone, camera) including editing and organization (iPhoto also organizes video fragments, but even my fellow geeks don't know that.)

Apple decided to kill their original iLife product (iMovie 2006) and replace it with a new 1.0 product called, not coincidentally, iMovie 2008. iMovie 2006 and iMovie 2008 are very different products with some overlapping and some distinct features -- but 2008 is definitely not a superset of 2006. In some ways iMovie 2008 is a significant step backwards from iMovie 2006. If you don't like it, one imagines Jobs saying, you can buy Final Cut Pro and new Mac to run it.

This is arguably a rather arrogant move, but we Apple customers are accustomed to this sort of thing. Those of us who knowingly sold our souls to Mephistophejobs knew there'd be days like this. The iPhone doesn't have, cut and paste, tasks or search capabilities (ok, there's a long list of missing basic PIM functionality), Aperture can't modify image dates and the database is unbelievably slow, iPhoto can't import/merge iPhoto Libraries, etc, etc. Apple's software gets dumber and dumber, but that's what non-geeks want. Geeks just have to suck it in -- for us the pinnacle of software development on any platform was probably the mid-90s.

That's what I thought, until I read this: Buy iLife '08 and get iMovie '06 for free.  This is so unlike Apple I'm a bit stunned. It's almost as though Satan were say "John, I'm really sorry about that eternal hellfire bit, I'll drop the temperature". They're effectively apologizing for the kill/switch move, and providing the old functionality for those who want it. They barely waited for the screaming to start.

So what happened? Is Jobs grip weakening? Is some non-satanic force emerging within Apple?

Wow. Next thing you know they'll build an iPhone I can buy, or maybe even, dare I dream, fix Aperture?

Jonathan Vos Post on Aug 8th, 2007 at 11:52 am

.... As to the far future, my article on this, which cited Freeman Dyson and others, which first published the idea that we are most likely simulations by a far future dilute electron positron plasma civilization, and which served as the extensively quoted basis (quotation marks accidently omitted) of some Greg Benford novels, is:

“Human Destiny and the End of Time” [Quantum, No.39, Winter 1991/1992, Thrust Publications, 8217 Langport Terrace, Gaithersburg, MD 20877] ISSN 0198-6686

In fairness to Benford, who I think is being criticized here [update 12/7/07: see comment by Vos Post -- this is not a criticism of Benford], science fiction writers have been talking about 'life in a simulation' at least since the early 1980s and I dimly recall Dyson as talking about it eons ago.

For related discussions, see:

• Ten cosmologies and Theory 10
• Life seem absurd? Maybe it is.
• George Bush; Deity of the Computer Simulation?
• http://www.faughnan.com/setifail.html#[9] (Footnote - Are You Living in a Computer Simulation? Nick Bostrom, Department of Philosophy, Oxford University. Philosophical Quarterly (2003), Vol. 53, No. 211, pp. 243-255.)
  
• In Our Time: Common Sense Philosophy: Descartes and Hume try to get out of their heads, and mostly fail to persuade anyone that they're not living in a simulation. Hume in particular seems to have struggled with the impossibility of proving he wasn't a "brain in a bottle", though it's easy to argue that Plato (and probably "Thog") was talking about a similar problem.
  

Inattention taxes: overcharging on checkout

Inattention taxes are the monies earned through overcharges. I'm fairly certain I pay a few hundred dollars of fraudulent or mistaken credit card and checkout transactions every year simply because I can't take the time to validate all my transactions. I just try to catch the thousand-dollar frauds that hit me very ten years or so.

So I pay my "inattention tax" and hope others, like Scott Gruby: fight my battles for me:

Target was issued a violation

I just got a call from the San Diego County Agriculture/Weights & Measures department about my complaint of Target overcharging me. They inspected the items I indicated I was overcharged for and also found that they were overcharged. In addition, they performed a routine inspection of 50 items and were overcharged on 9 of them. If that wasn’t enough, they got cited for not having the required notices about being overcharged.

I’ve never seen a public agency act so quickly on a complaint. While my overcharges were pennies, the inspector said that he was overcharged $5 on an item.

I suspect these overcharges are not planned, they are merely emergent. If an organization focuses limited resources on preventing undercharging, they will necessarily diminish resources that prevent overcharging. So the balance will shift to err on the side of overcharging. Scott's intervention won't make the problem go away, but he's helping keep it in check. If he had a micropayment donation box (soon to come via Amazon) I'd send him a $1 for doing what I can't afford to do ...

Information (and data) Visualization: The future always arrives late and unexpectedly

I've intermittently taught data visualization to grad students. It's been the same old thing for years -- poor quality scans of examples from 20-30 year old experiments. Nothing seemed to make it out of the lab. So I was surprised when a colleague (Andrew) pointed me to an unexpected reference: 

Data Visualization: Modern Approaches

This article gives a nice overview of various visualization technologies that people are experimenting with.  Some seem like eye candy, some seem genuinely useful and could be applicable to clinical applications.  The articles and resources section gives some good links to other resources on the web, such as visual complexity which has hundreds of different ideas for visual representation of topics....

Andrew also pointed me to the interactive Flash based BBC British History Timeline. Lovely, and a very handy reference to use with "In Our Time" podcasts. These kinds of visualizations do make me hope Apple is able to create a decent Flash client for OS X (and thus for the iPhone). (since Adobe can't).

I expect the data visualization post will be widely used by anyone lecturing on information/ knowledge/ data visualization. It's also a golden example of how much power Blogs (Smashing Magazine is really a blog in drag) provide. Once upon a time, this would have had to be a book, with an enormous barrier to publication. Today this unattributed article has "Views: 70392 by 52501 users". As near as I can tell this is the author information:

Smashing Magazine is maintained by Sven Lennartz, the owner of the Dr. Web Magazine and Marketing Tricks and Vitaly Friedman, the creator of The Web Developer’s Handbook - with a little help from Christiane Rosenberger.

Of course I've added SM to my bloglines subscription list. Anyone who can do this must have more to offer in the archives and the future ...

Hedge funds and private equity: a hedge fund manager's perspective

Freakonomics gets some great responses from a hedge fund manager. No respectable senator can claim any longer (though really, they never could) that there's a good reason to exempt hedge fund managers from taxation.

Excerpts below ...

Freakonomics Blog � Your Hedge Fund Questions, Answered

Q: (1) Do you think the Senate proposal [to raise taxes] really could cause a flight of the industry overseas, as Ben Bernanke hinted?

A: First, let me state the obvious: there is no public policy reason for hedge fund and private equity managers to pay a lower tax rate than teachers, doctors, or lawyers. ..

... let’s not kid ourselves — the tax code is a gift to the industry...

... from a fairness perspective, it is a no-brainer. The notion that the most profitable industry in the history of mankind (I hyperbolize, but on a per-person basis, this might in fact be true) requires a lower tax rate to take risk and make investments, simply does not square with logic. I know of no manager who would stop working or stop investing as a result...

Q: I’m curious as to what degree the emergence of hedge funds has changed business strategy....

.... Often, companies go private when activists chase management into the arms of LBO shops willing to put a level of debt on corporate balance sheets that public investors would find imprudent. As the economy slows or credit markets tighten, these companies will have trouble making their debt payments, and — just as the LBO boom in the 1980s burst — lenders and possibly private equity investors will be left holding the bag...

Q: Do you believe that hedge funds provide a social good? ...

.... What specific benefits to society as a whole are provided by hedge funds? I do believe that, starting with the 1980s bull market, we have seen a society-wide reallocation of human resources. And it is unfortunate that the “best and the brightest” no longer seem to want to go into government or medicine or teaching (I did say I’d be generalizing here), and instead seem to gravitate to the best-paying professions. In other eras, I believe that was not the case to the degree it is today. Hedge funds didn’t make this happen — back in the 1980s and 1990s it was the investment banks that siphoned off the talent — but the industry has certainly made matters worse...

I chose the quotes that I found most interesting, but our manager also says that hedge funds, once they become available to retail investors, will be competitive alternatives to conventional mutual funds.
