Who are the Publishers of Computer Science Research?

To answer this question, I downloaded the DBLP database and used the DOI publisher prefix of each publication to determine its publisher. I grouped the 3.4 million entries by publisher and joined the numeric prefixes with the publisher names available in the list of Crossref members. Based on these data, here is a pie chart of the major publishers of computer science research papers.

Interoperability, at Last

Language is a very powerful way to describe behavior. Therefore even when I create pictures, instead of dragging around my mouse, I use declarative tools like GraphViz, gnuplot, and UMLGraph. These allow me to describe what I want to draw, instead of how I want the end-result to look like. The truth however is that the end-results are not always perfect. Today I realized that the state of the art has advanced to the point where I can create the drawing declaratively, and then visually polish the final drawing.

Using and Abusing XML

Words are like leaves; and where they most abound, Much fruit of sense beneath is rarely found.

Backwards Compatibility in Office Open XML

As a member of my country's national standards body committee on electronic data processing, I lately spend considerable time deliberating what our position should be in the upcoming Office Open XML ISO Ballot Resolution Meeting in Geneva. My biggest objection concerns large parts of the standard that are proposed to live in an Annex containing normative descriptions of deprecated features that will only be used by existing binary documents. The rationale behind this decision is backwards compatibility. My opinion is that this solution is counterproductive for a number of reasons.

Make vs Ant: Observability

I've long felt uncomfortable with ant as a build management tool. I thought that my uneasiness stemmed from the verbose XML used for describing tasks, and the lack of default dependency resolution. Today, email from a UMLGraph user struggling with a complex ant task made me realize another problem: lack of observability.

Xerces v Flex

What is the fastest way to process and XML file? I was faced with this question when I recently wanted to process a 452GiB XML file; for this amount of data speed matters. Some obvious choices were XML libraries, hand-crafted code, and lexical analyzer generators.

If STL Had Been Designed by a Committee

I've been reading on XML schema, and it's embarrassingly obvious that it has been designed by a committee.

Tool Writing: A Forgotten Art?

Merely adding features does not make it easier for users to do things—it just makes the manual thicker. The right solution in the right place is always more effective than haphazard hacking.

— Brian W. Kernighan and Rob Pike

XML Abstraction at the Wrong Level

Over the last month I've encountered two applications that use XML at the wrong level of abstraction. Instead of tailoring the schema to their needs, they use a very abstract schema, and encode their elements at a meta level within the XML data. This approach hinders the verification and manipulation of the corresponding XML files.

XML Versus Text Files

The JDepend package dependency analyzer can output its results either as XML or as plain text. Instead of using the XML output, I found myself processing the text output using awk. Am I becoming tied to old-world thinking, or are text files easier to process?
