We Recommend These Resources Java 8 developments are starting to dominate the news again. Recent posts cover extending Milestone 7 of JDK 8 to ensure its feature complete, the Date/Time API now available in Java 8, and updates to the Java Tutorials to cover some Java 8 features. Extending JDK 8 M7 Mark Reinhold wrote in JDK 8 M6 status, and extending M7 that the "best results" of an M7 "Developer Preview Release" would be obtained if that M7 release was "feature complete." In particular, changes related to Project Lambda are best incorporated before the M7 release. Recent Java 8 News

Azul Systems Announces New Initiative to Support Open Source Community with Free Zing JVM SUNNYVALE, Calif., July 30, 2012 -- Azul Systems, Inc. (Azul), the award-winning leader in Java runtime scalability, today announced an ongoing commitment to the Open Source community by making Zing freely available to Open Source developers and projects for use in development, qualification, and testing. The new initiative enables Open Source applications supporting commodity x86 servers running Red Hat Enterprise Linux, SUSE Linux Enterprise Server, CentOS and Ubuntu Linux to take full advantage of Zing’s unique features and capabilities. “Our goal is to make Zing the de facto choice for Open Source developers to achieve the most consistent Java performance and scalability,” said Scott Sellers, Azul Systems president and CEO.

Release 5.0 has several source and binary incompatibilities, and introduces quasi-succinct indices. Benchmarks on the performance of quasi-succinct indices can be found here; for instance, this table shows the number of seconds to answer 1000 multi-term queries on a document collection of 130 million web pages: Both engines were set to just enumerate the results without scoring. The column labelled MG4J* gives the timings of an artificially modified version in which counts for each retrieved document have been read (MG4J now stores document pointers and counts in separate files, but Lucene interleaves them, so it has to read counts compulsorily). Proximity queries are conjunctive queries that must be satisfied within a window of 16 words. MG4J: Managing Gigabytes for Java™

Generic class names to avoid We Recommend These Resources Java (Oracle Java update 2) has many classes with the same generic name. To avoid further confusion, I suggest avoiding these names if you can. Most repeated The following class names are repeated, 19 Handler, 16 Messages, 13 Util, 10 Element, 8 Attribute, 7 SecuritySupport, 7 Node, 6 Provider, 6 Header, 6 FactoryFinder, 6 Document. 5 SOAPBinding, 5 Repository, 5 Ref, 5 ORB, 5 Name, 5 Constants, 5 Connection, 5 Comment, 5 Binding, 5 Attributes, This excludes the Apache XML library which repeats many names. If you include these libraries there are 26 classes called SecuritySupport.

Faux' Blog » Java stacktraces straw man It’s a sad fact of life that many developers spend a good deal of time staring at stack traces. My personal favorite situation is when you get to:Exception in thread "main" java.lang.NullPointerException at com.goeswhere.dmnp.linenos.B.foo(B.java:13) ..and, line 13 is:

High-performance pattern matching algorithms in Java The Java language lacks fast string searching algorithms. StringSearch provides implementations of the Boyer-Moore and the Shift-Or (bit-parallel) algorithms. These algorithms are easily five to ten times faster than the naïve implementation found in java.lang.String. Download StringSearch – high-performance pattern matching algorithms in Java
