Last week we discussed the Bank of Tokyo – Mitsubishi UFJ ATM problem in 2008 which was related to the integration of systems following a merger. Seven Bank’s ATMs were expecting a Katakana character but were sent a Kanji character. As a result many ATMs were shut down.

VATSIM is an organization which provides simulated air traffic control services. The services are provided through user developed extensions to the Microsoft Flight Simulator, user-developed controller workstations, and a network of servers. Using these services, a user piloting a virtual aircraft can file a flight plan and “fly” guided by other users who act as controllers. VATSIM has about 250,000 members who are virtual pilots and virtual controllers. Vatsim’s software is developed collaboratively by its members. Pilot and controller training is offered online.
Here’s a demonstration video:
In the following article, Earl Steven Raymond discusses open source development and why it can produce reliable software. He discusses traditional hierarchical “cathedral” development models vs. the “bazaar” model where users are part of the development community. Quotable (from the article): “Given enough eyeballs, all bugs are shallow”.

The cost of a gallon of HP printer ink is $8000 making it more expensive than a first growth Bordeaux wine! A gallon of Chateau Lafite Rothschild costs about $2000 to $4000 depending on the vintage. The article states that HP’s profit margin on supplies is 14-16%. If this is correct, some of the cost is certainly related to the cost of producing the ink. I suspect some of the cost is also related to the cost of producing disposable cartridges (which contain the nozzles for the ink), and the allocated cost selling subsidized printers.
The second article discusses Kodak’s printer strategy vs HP’s. Kodak seems to be moving to a model where they charge more for the printer but less for the ink — reducing the cost for each printed page.
