At #Pragma Conference 2015, Marcus Zarra, author of Pragmatic Bookshelf Core Data, described three approaches to using Core Data in a multithreaded environment and tried to clear up how Core Data should be used in 2015.
The MagLev project has released version 1.0 of their Ruby VM. The Ruby implementation is based on the GemStone/S Smalltalk VM which comes with GemStone's distributed cache, ACID transactions, and persistence system (OODB). InfoQ caught up with Monty Williams of the MagLev project to talk about where MagLev fits on the NoSQL spectrum, and much more.
The long awaited MagLev Ruby implementation, based on GemStone Smalltalk, is now available in a public alpha release. While not quite ready to run Rails, it does support frameworks like Rack and Sinatra. MagLev comes with full support for GemStone's mature distribution and persistence features.
ODBMS.ORG has added persistence patterns to its collection of resources for educators, students, professionals, and open source practitioners. Three pattern collections comprise the initial offering in this area. A Best Persistence Pattern Award, is planned for any pattern submitted prior to May 29, 2009.
Gemstone's Maglev Demo at RailsConf sparked a lot of interest. A new project experiments with bringing this kind of transparent clustering to JRuby using Terracotta. We talked to Fabio Kung who's been experimenting with this approach.
In a recent blog post, Martin Fowler, a renowned software thought leader, observed at last week's QCon that the deep freeze in thinking about databases in application architectures is thawing. The world has been stuck using RDBMS databases for every application use case, but the time has come to also consider RISC RDBMS or distributed document-oriented databases.
Roberto Zicari, from ODBMS.org, collected interviews and stories from several users of Object/Relational mapping technologies. The main point of the cases was around "impedance mismatch" between the object technology in the domain model and the relational technology in the data model.
In this interview from QCon 2008, Avi Bryant talks about his Smalltalk web framework Seaside and DabbleDB. Also: Avi explains how DabbleDB uses Smalltalk images for persistence instead of an RDBMs and how to make Squeak scale.
McObject® has released Perst™ version 3.0, a major upgrade of its open source, object-oriented embedded database system. Persist is dual licensed (commerical and GPL), allowing it to be used freely in non-commercial applications.
Avi Bryant talks about working on MagLev, a Ruby implementation built by GemStone. Avi explains the reasons for MagLev, the merits of GemStone's distributed OODB features, and more
OODB vendor Gemstone works on a Ruby VM called MagLev. Working with Seaside's and DabbleDB's Avi Bryant, Gemstone bases the Ruby runtime on their Smalltalk VM to offer performance and powerful persistence features. We talked to Avi Bryant and Gemstone's Bob Walker about the technology behind MagLev and the plans for it.
db4o has been growing fast lately, having recently released v7.0 beta of their flagship db4o embedded OODBMS, and claiming over 30,000 deployments of their open source ODBMS. Is this a sign of changing times reflecting the ODBMS landscape?
Gemstone is working on Ruby support for their Object Database products, starting off with JRuby. We talked to Alan McKean from Gemstone about what's to come, technical details and Gemstone's plans with Rubinius.
