* CheckRDFSyntax and Schemarama Revisited "...thinking about our expectations of RDF “validation” can teach us a lot about RDF’s value, about it’s relationship to XML, and about the things we should focus on building next."
* sparql fast as hell "But the real astonishing thing is that SPARQL of this kind is also fast as hell (10-500ms)...In simple words: this is a fulltext scan over all properties of all statements...triplecount: 371994"
* Data First vs. Structure First "Next time you spend energy writing the ontology, or the database schema, or the XML schema, or the software architecture, or the protocol, that 'foresees' problems that you don't have right now think aobut "you ain't gonna need it", "do the simplest thing that can possibly work", "keep it simple stupid", "release early and often", "if ain't broken don't fix it"and all the various other suggestions that tell you not to trust design as the way to solve your problems. But don't forget to think about ways to make further structure emerge from the data, or you'll be lost with a simple system that will fail to grow in complexity without deteriorating." Rifting on a familar theme.
* PlayStation 3 processor could support Mac OS X Tiger ""The operating system has also yet to be clarified. The integrated Cell processor will be able to support a variety of operating systems (such as Linux or Apple's Tiger)."
* CollectionClosureMethod "The each method takes a one argument block (Ruby and Smalltalk both refer to closures as blocks). It then executes the block on each element in the collection. It essentially is the same as the foreach statement you find in many modern languages (and recently arrived in Java with 1.5). With these languages the foreach method is all you get, but with collections and closures the each method is just the start."
