1. # The Semantic Web: Is It Done Yet?

Peter Van Dijck has composed an interesting summary of the themes that arise in debates about the Semantic Web, including the recent discussion of Shirky’s essay. I follow this discussion with some bemusement and distance. I don’t think it’s an exaggeration to claim that I’m the …

2. # XML Tramp Data Model

I’ve been playing with Aaron Swarz’s XML Tramp as an intuitive/pythonic way of processing XML. The model/syntax isn’t explicitly documented, but from the source and (mostly) examples, this is what I’ve figured out:

XML Tramp Conventions

• Elements have a list of children ‘[]’

• iterate over …

3. # Information Theory and Entropy

The way I think of Shannon’s information theoretic concept of entropy is as “uncertainty.” Or, in another approach, Shannon’s entropy — and there are many types of entropy — is a measure of how resistant “information content” is to compression: more entropy/uncertainty, means less redundancy, and consequently less compression …

4. # "Reliable" HTML Code

I’ve been eagerly waiting for the next release of Quanta and its WYSIWYG mode (called “Kafka”). I’m hoping it’ll be in KDE 3.2. However, looks like Lindows might beat them to the punch with Nvu. Yet, while I’m confident Quanta will support valid (X)HTML …

5. # Two Little Ideas for Pyblosxom

1. Create a format for txt/html entries in which I can include the trackback URLs of those sites I want to send a trackback ping to when I publish it. For example:

`<p class="trackback-ping">`

`http://www.gothamist.com/mt/mt-tb.cgi/5594 </p>`

These wouldn’t be shown in …

6. # Polynomial versus Exponenital

I found this nice simple definition on Usenet that I like:

With a polynomial, it is the base number that varies. The exponent is given.

Ex. x\^2 (x is the base number, 2 is the exponent.)

With an exponential, the exponent varies. The base number is given.

Ex. 2 …

7. # The "Not Invented Here Yet" Syndrome

Matt’s entry about being “crushed” by finding a project that already satisfies part of something he’s been planning reminded me of another recent discussion. My brother had a project he was excited to work on, but he lost his enthusiasm when he learned other folks were already working …

8. # Verisign: The Stink From Crossing a Domain

Siva Vaidhyanathan and I have been discussing the big stink related to the “Verisign thing.” Regardless, of the technical issues involved, the stink is, in part, a smell arising from a contentious issue crossing the boundary of an expert (technical) discipline into general public discussion.

Previous to this change by …
