2001 A Space Odyssey

2001: A Space Odyssey (film).

This is the 1968 sci-fi film made by Stanley Kubrick and Arthur Clarke, famous for its pioneering depiction of technology, artificial intelligence, anthropology and human evolution etc. The supercomputer HAL 9000 is a famous figure of AI, which possess not just strong computational power, but also human-like emotions.

The story is centered around a sentinel rock found on Moon, which sent signal to Jupiter. A mission group is sent from early to investigate the signal destination on Jupiter. Of the crew of 5 humans and HAL, only HAL knew this true purpose. HAL killed 4 crew members in fear that they would shut him down and interfere with the trip mission. One crew survived, shut down HAL, and arrived at the Jupiter.

In my opinion, the 1968 movie is superb in its whimsical sense of sci-fi thoughts. The scenes setup both internally inside spacecraft and externally in the universe are still convincing today. But lack of dialogue and slow pace of storyline may not be liked by some people.

There are 4 episodes of the Space Odyssey series, published as 4 books. The first 2 were made into movies in 1968 (2001 A Space Odyssey) and 1984 (2010 Space Odyssey II). The later two are set in years 2061 and 3001. The 1968 movie is regarded as among the best movies in history. Before these 4 books, Clarke published a short story "The Sentinel" (PDF) in 1951, which he later expanded into the "2001 A Space Odyssey" in 1964, and further rewritten as a movie.

Arthur Clarke's books on the Space Odyssey series can be found here.

The magic squares

The matlab7 book I'm reading uses Durer's matrix as an example. This leads to my finding of the wiki page on magic squares. Sleek, or sick?

Another unrelated but similarly magical description on numbers encrypted in architectures: Secrets In Plain Sight - Art, Architecture & Urban Design, and here on youtube.

Problems/Bugs with MSSQL server

There are some noticeable issues with MSSQL Server 2008.

- Cannot call function from remote machine.
- IDE issue: right click on a database, choose "Property -> Files", changes made to the Autogrowth dialog box sometimes cannot be saved. One has to repeat the steps several times before the change can take effect.
- Issues with extended property: 1) not included in replication synchronization process, and 2) no Information_Schema view is provided for extended properties. (from here)
- Also for extended property, I sometimes need to return extended properties of all the columns in a table, the order of returned list is un-deterministic and causes a headache when I want to display the columns in a certain order.
