Saving fuel via wireless Internet and the SUV v. the tree

While driving from Boston to Washington, DC there were two occasions where a national wireless Internet would have saved some fuel.  The first occurred when impulse dictated the following of a “New Jersey State Aquarium” sign off the NJ Turnpike.  This attraction was in the car’s GPS database so I asked the machine to change its destination. However, it turned out that the aquarium was closed for renovation until May and the side trip was merely a fuel-wasting detour.


The second occasion was en route to Longwood Gardens, near Wilmington, Delaware (fabulous greenhouses this time of year).  A bad accident on the other side of the road would have made it much faster to stay on the Interstate for another few exits.


The GPS is a $1000 machine with a powerful computer, a full North American database on a microdrive, and a large LCD display.  Adding an 802.11 receiver would add almost nothing to the cost.  If the U.S. had a free universally available wireless Internet companies such as Garmin would build Internet transceivers into their products so that they would know (1) current opening hours of attractions, and (2) the locations of traffic jams to route around.


We complain that we are running out of oil but we aren’t willing to lift a technological finger to conserve any.


[Note: The traffic accident was an interesting example of Mutually Assured Destruction via SUV.  The driver of a GMC SUV had lost control of his vehicle and spun it around, ending up by smashing into a tree. Because his vehicle was so ponderously bulky the impact had knocked the tree out of the ground.  Sadly, in a Coyote v. Road Runner-esque turn of events, the tree proceeded to fall on the SUV’s roof.  In an effort to keep SUVs from rolling over there apparently isn’t much structure up there.  So the entire roof of the SUV had been flattened by the tree.]

Strip Mall Land = Comforting

Turning off New Jersey Route 17 toward my cousin’s house in Allendale it occurred to me that maybe opponents of sprawl and strip malls are overlooking one bright spot.  There is something comforting about driving down Route 17 or the Rockville Pike in Maryland.  You know that if you have a car and a credit card you’ll be able to get everything that you might conceivably ever need and, after all, isn’t that what American life is all about?

Aloha to Death Row

http://www.nytimes.com/2005/03/17/national/17peterson.html is an interesting NY Times story because it features Laci Peterson’s stepfather in a Hawaiian shirt talking about Scott’s trip to Death Row.  One does not see that ever day.  The article also contains



In a wrenching display toward the end of the hearing, Ms. Peterson’s mother, Sharon Rocha, assumed the roles of her daughter and the grandchild that was never born, pleading aloud in a trembling voice for “Daddy” not to kill “Mommy and me.”


Assuming the role of a cerebral palsy baby was one of John Edwards’s favorite courtroom tricks.  Perhaps this will be commonplace now.

Why can’t phone companies go straight?

An interesting juxtaposition… from a couple of months ago:



[Bernard Ebbers,] The ousted chief executive of a giant telecommunications company rocked with an accounting scandal told his congregation on Sunday that he was innocent of wrongdoing. Appearing at Easthaven Baptist Church in Brookhaven, Miss., as usual to teach Sunday school and attend the morning worship service, Bernard Ebbers made his first public comments about WorldCom since the disclosure of $3.8 billion in improper accounting last week, The Wall Street Journal reported.”I just want you to know you aren’t going to church with a crook,” Ebbers addressed the congregation at the end of the service.


And from today’s London Times:



BERNIE EBBERS, the former chief executive of WorldCom, faces the rest of his life in jail after being found guilty of orchestrating the biggest fraud in American corporate history.  … The jury of seven women and five men found Ebbers guilty on all counts in a Manhattan court.


Why is it that phone companies are always defrauding either customers or investors or both?

If they can put a man on the Moon….

Two talks at MIT this week have been thought-provoking in similar ways.  The first was by a physics professor, Frank Wilczek, who recently won the Nobel Prize for his work on the Strong Force, which holds together quarks to form atomic nuclei.  Wilczek showed some impressive drawings from the latest European particle accelerators in which subatomic particles are smashed together until the quarks start flying out.  (This lecture is available at http://web.mit.edu/nobel-lectures/.)  John Grotzinger, a geology professor, gave a talk about his experience with the Mars Rovers, which found evidence for flowing water on Mars in sedimentary rocks.  The Rovers communicate with an orbiter and can also communicate directly with stations on Earth.  In Grotzinger’s more than one year with the project they’ve never had a communications problem.


So… if human minds can get together to make ever-better particle accelerators, why can’t anyone build a reliable inexpensive nuclear power reactor?  And if the Mars Rovers can call Pasadena, how come nobody with a T-Mobile phone can make a call from most spots on the MIT campus or along Memorial Drive?


In the 1970s people would ask questions of the form “If they can put a man on the Moon, why can’t they do X?”  What would be the modern equivalent?  The one great human achievement of our current decade that can be compared to the lack of accomplishment in most bureaucracies?

Business schools redefine hacking to “stuff that a 7-year-old could do”

When universities created business schools in the 20th Century traditional academics decried the collapse of standards.  Instead of students studying Literature, Art, History, and Science they would be going through the motions of a scholar while occupying their minds with things that formerly had been learned at a desk as an apprentice in a dreary Victorian counting house.  Now in the 21st century the B-schools are degrading the term “computer hacking”.


Here are the facts:



  • Harvard and a bunch of other B-schools with a collective IT budget of maybe $50 million decided that writing Perl scripts was too hard so they outsourced Web-based applications to a company called ApplyYourself.
  • You’d think that the main advantage of a centralized service such as ApplyYourself would be that a prospective student could fill out one application and the information be sent simultaneously to many schools.  However, this is not how it works.  Each school has a totally separate area with ApplyYourself.
  • All the smart young Americans have gone to law, business, and medical school.  Companies don’t like to hire old people (> 30 years) to write computer programs because it saddens them to see old folks doing something so degrading.  Thus ApplyYourself hired whoever was rejected by professional schools to write up some Visual Basic scripts to process HBS and other B-school applications.
  • The ApplyYourself code had a bug such that editing the URL in the “Address” or “Location” field of a Web browser window would result in an applicant being able to find out his admissions status several weeks before the official notification date.  This would be equivalent to a 7-year-old being offered a URL of the form http://philip.greenspun.com/images/20030817-utah-air-to-air/ and editing it down to http://philip.greenspun.com/images/ to see what else of interest might be on the server.
  • Someone figured this out and posted the URL editing idea on the BusinessWeek discussion forum, where all B-school hopefuls hang out and a bunch of curious applicants tried it out.
  • Now all the curious applicants, having edited their URLs, are being denied admission to Harvard and, due to the fact that  universities form cartels to fix tuition prices and other policies, presumably to the other B-schools as well.

One interesting data point is that I once supervised a couple of MIT students building an online system for submission of essays to be graded.  MIT and a bunch of other schools have writing requirements.  Students submit essays.  These are held in confidence from other students.  A subset of users are authorized to grade essays and they are handed essays to evaluate.  One server with a single database is programmed to handle students and evaluators from many different schools and keep everything that should be separate separated.  The students building this system had never programmed in SQL before.  Nor had they ever written a Web script to glue their SQL code to an HTML template.  Nor had they ever written HTML before.  The entire project, which requires the same workflow and main features of the ApplyYourself service, took them three months at 20 hours per week.  Those kids are probably just graduating from med school now and preparing for their careers in radiology…


In the 1960s the term “hacking” meant smart people developing useful and innovative computer software.  In the 1990s the term meant smart evil people developing and running programs to break into computer systems and gain shell access to those systems.  Thanks to Harvard Business school the term now means “people of average IQ poking around curiously by editing URLs on public servers and seeing what comes back in the form of directory listings, etc.”


[Update:  People have been asking me whether I think the schools are justified in rejecting the applicants who mucked with ApplyYourself’s URLs.  Had I been an MBA applicant and heard about this security hole I probably would have tested it out.  Not so much out of curiosity as to whether I’d gotten in but mostly to see if a school with nearly $30 billion in assets really was so contemptuous of quality in IT and also to see just how far the Web development industry has slid from its apex (probably 1994, when 5 reformed Lisp hackers built Amazon.com out of C CGI scripts talking to Oracle).  I did something similar when writing Philip and Alex’s Guide to Web Publishing.  I needed examples of Microsoft Active Server Page source code.  There was at one time a bug in IIS/ASP that enabled anyone to view the source code by appending “::$DATA” to any .asp URL.  Months after Microsoft had released a patch for this bug, I surfed around and found scripts at lots of prominent public servers, some of which scripts contained database usernames and passwords.  I published the results in http://philip.greenspun.com/panda/server-programming#ASP, which was turned into a hardcopy textbook by Harcourt.  So it seems that my curiosity into just how incompetent an institution with $billions in assets could be would have led to me failing the ethics test, being convicted of hacking, and being denied admission to a top business school.


Where would I personally draw the line?  A grad student at MIT figured out that Fandango, the movie ticketing service, was passing the price of the movie ticket as a hidden form variable in the HTML instead of doing the pricing on the server at the final page.  He was able to edit the HTML form in Emacs and submit it to Fandango and buy tickets for any price that he felt was fair (being a grad student, his preferred price for tickets was $0.25).  He invited me to try it out but it but I thought that either Fandango or a movie theater would end up having to make up the difference and it didn’t feel right to take their money.  The HBS/ApplyYourself situation falls into the “poking around with a browser” category where you get to see stuff but the Web publisher hasn’t been injured because they still have the stuff on their server (one of the strange characteristics of the digital age).  As progressively dumber programmers build progressively more complex systems we will see more of this kind of attempt to paper over coding mistakes with lawyers, sanctions, policies, and laws.  Hollywood and the RIAA are usually the most successful at getting the government to do their bidding.  Thus I predict that one day Disney will have a Web site where you can buy access to any of their movies.  Because all of their profits are being used to pay executive salaries this will have to be built at extremely low cost.  Deficiencies in the softwrae will enable vast numbers of Americans to download Bambi for free, their ISPs will be forced to rat them out, and they will all get to see Martha’s Stewart’s cell in West Virginia first hand…]

Aerial photos of the spiral jetty in the Great Salt Lake

Having finally gotten Photoshop scripting sort of under control, http://philip.greenspun.com/images/20030817-utah-air-to-air/ contains some photos of my old airplane flying over the spiral jetty artwork in the Great Salt Lake.  These were taken by Jenny Reinman from a physician-piloted Cessna [a plurality of private aircraft owners seem to be MDs] while her husband Paul Reinman and I flew in the Diamond Star.

Syria is able to control Lebanon with 14,000 soldiers

Syria and Lebanon have been in the news latelyLebanon has a population of 3.7 million.  Syria is able to control these people with just 14,000 soldiers, according to the latest articles, and to judge by the tens of thousands of supporters who rallied today in Beirut, Syrian control of Lebanon is just fine with most of the Lebanese.  This is a remarkable achievement considering that the U.S.-led coalition has roughly 150,000 troops in Iraq for their 25 million people and Iraqis don’t seem to be turning out in any great numbers to show public support for the foreign soldiers to continuing hanging around.  One wonders if we should not have outsourced the Iraq occupation to Syria…
