MagLev, Ruby VM on Gemstone OODB, Wows RailsConf
murphee ends along a report from InfoQ: "Gemstone demoed [MagLev,] their Ruby VM built on their GemStone S64 VM, to an ecstatic audience. Gemstone's Smalltalk VM allows OODBs of up to 17 PetaBytes, with none of the old ActiveRecord nonsense: the data is persisted transparently. The Gemstone OODB also takes care of any distribution, allowing the Ruby VM and data to scale across many servers (Cheerio, memcached!). There's also an earlier quite technical interview with Gemstone's Bob Walker and Avi Bryant about MagLev." -

Scalable Nonblocking Data Structures
An anonymous reader writes "InfoQ has an interesting writeup of Dr. Cliff Click's work on developing highly concurrent data structures for use on the Azul hardware (which is in production with 768 cores), supporting 700+ hardware threads in Java. The basic idea is to use a new coding style that involves a large array to hold the data (allowing scalable parallel access), atomic update on those array words, and a finite-state machine built from the atomic update and logically replicated per array word. The end result is a coding style that has allowed Click to build 2.5 lock-free data structures that also scale remarkably well." -
Red Hat Sued Over Hibernate ORM Patent Claim
fmarines writes "Firestar Software has filed a patent claim against Red Hat for infringing on a patent Firestar filed in 2000 covering O/R mapping. The amount of the lawsuit was not disclosed. The complaint centers around JBoss 3, and the patent claims that JBoss was given prior notice that marketing, distribution, and support services violates Firestar's patent, and that Firestar 'has suffered and will continue to suffer substantial damages.' Firestar produces the ObjectSpark, an transactional object mapping engine which appears to not have had a new release since May 2003, according to the Firestar press release page."
