Migration

With the announcement of JRuby in Glassfish or the end of mongrel it seems to offer Sun the hope of capturing more developers not just from Ruby but from .NET. Many people from both Java and C# worlds jumped to Ruby and it occurred to me that .NET developers using Netbeans for Ruby development may notice that there's a suprisingly good C# clone under the covers.

Attacking the Boundary of Ignorance

• The Ontology Integration Problem "The reason I think a mapping tool is a critical need is that I think while in theory it's a nice idea to imagine ontologists reusing ontologies from one another, in practice many ontologists (especially those working on large complex ontologies) would rather write their own internally consistent ontologies and map them to other ontologies rather than importing other ontologies into what they are making and then having to deal with all the inconsistencies and confusion that arises from doing that."


• Language Wars "I know Paul told you that he made his app in Lisp and then he made millions of dollars because he made his app in Lisp, but honestly only two people ever believed him and, a complete rewrite later, they won't make that mistake again.
  
  The safe answer, for the Big Enterprisy Thing where you have no interest in being on the cutting edge, is C#, Java, PHP, or Python..."


• Circles of knowledge and boundaries of ignorance "...earning can be viewed as either expanding your circle of knowledge or as increasing your boundary of ignorance. So, the more you learn the more you know, but also the more you know that you don’t know. Depending on your temperament, this can be either encouraging or discouraging to your efforts to continue learning."


• Bigtable: A Distributed Storage System for Structured Data From Google Research Papers


• JUnit 4 vs. TestNG A few advantages of TestNG such as dependencies and providing test data (even complex objects).

Supping from the Information Firehose

* Oracle 10g Support for RDF "There are procedures provided to search the RDF models with a language that looks like a bit like SPARQL...The search is pretty nice because you can join your search on standard SQL tables, thus combining both your triple model and relational models together.

Oracle also has Rule support, in the form of Rule Indexes. A builtin set of rules for RDF Schema (RDFS) semantics is provided, which is a very nice touch. You are also free to create your own rules, both with the query pattern matching and filters."
* An Atom Store With links to people wanting to create a non-SQL store for Atom, including the very good Bosworth's Web of Data (original here) which is largely about why new databases should not be like Oracle but should distribute the processing (no views, triggers, etc).
* RDFAuthor does SPARQL "Damian is working on a new version of RDFAuthor that generates SPARQL queries (instead of the older Squish notation). It can also (not sure which protocol(s)) get results from a query service." I liked the original RDFAuthor - good to see an update is underway.
* Wrapping rdflib's Graph around a 4RDF Model "I wrote a 4Suite RDF model backend for rdflib, that allows the wrapping of Graph around a live 4Suite RDF model. Finally, I used this backend to execute a sparql-p query..."
* Secrets of lightweight development success, Part 7: Java alternatives Closures, Continuations, Metaprogramming and Reflection: "In short, the Java language just isn't a very productive applications language. The founders made some wise compromises to wrestle control away from C++, but we're starting to pay for those compromises."
* ONJava 2005 Reader Survey Results, Part 1 "Eclipse (76 percent), NetBeans (21 percent), None (17 percent), IntelliJ (13 percent)...JBoss (38 percent), None (28 percent), WebSphere (21 percent), WebLogic (20 percent)"
* Language Innovation: C# 3.0 explained "...most of the features of C# 3.0 are, arguably, nothing but syntactic sugar designed to make programming more productive..." One of the things that was (originally) good about Java was the lack of syntax (I thought anyway!).
* KVM over IP
