Postel’s Law: Not Sure Who To Be Angry With

One of my research interests is finding the principles that underly the management of information, complexity and uncertainty. When something as simple as a web-form is called “technology” it is time to step back and examine your principles. One principle I am not sure about Postel’s law. It doesn’t hold often enough to be relied on and when it fails I am not sure who to be angry with. Continue reading Postel’s Law: Not Sure Who To Be Angry With

Should your mom use Google search?

Today’s question is: “should your mom use Google search?” It it is a good thing that Google has directly told us that their motto is “don’t be evil,” as their systems are subtle and difficult to evaluate.

Microsoft Store Again

Microsoft is once again going to try its hand at retail stores (for example see the following CNET article). From my experience I think this is going to be horrible. But it does not have to be- Microsoft (if it had the will) could produce a great store that is profitable and improves the world. Here is my quick history and wish list.

Map Reduce: A Good Idea

Some time ago I subscribed to The Database Column because it would be fun to see what these incredible people wanted to discuss. We owe much of our current database technology to Professor Stonebraker and Vertica sounds like an incredible product. And I definitely want to continue to subscribe.

However, the reading experience is marred by some flaw in their RSS system that keeps marking the article “MapReduce: A major step backwards” as a new article. This causes the article to appear in my RSS reader every few weeks as “new.” This wouldn’t bother me too much except that the article runs so counter to experience that it is itself offensive.

Something I don’t get about business and bailouts

I don’t really know what the right answer to the $700 Billion Dollar Bailout Question is (I have not read the bill, and I wonder if the bill really describes what would happen). But the whole situation does remind me of a related question: is it really the end of the world if the “credit markets freeze?” It is a disaster if the equity markets tank for a period of longer than a year or so (prevents people from retiring and so on)- but I am not sure if all of the consequences we are being told really follow.

I know, I am the one being a jerk

The other day’s blog post and a recent Andrew Binstock interview of Donald Knuth made me think more about how the ACM is really not serving the interests of computer science. Continue reading I know, I am the one being a jerk
