MySQL toolmaker Daniel Nichter provides a look at 10 must-have free and open source tools for MySQL. 'MySQL has attracted a vibrant community of developers who are putting out high-quality open source tools to help with the complexity, performance, and health of MySQL systems, most of which are available for free,' writes Nichter, who was named 2010 MySQL Community Member of the Year for his work on maatkit. From mydumper, to mk-query-digest, to stalk and collect, the list compiles tools to help back up MySQL data, increase performance, guard against data drift, and log pertinent troubleshooting data when problems arise, each of which is a valuable resource for anyone using MySQL, from a stand-alone instance to a multiple-node environment.

The release of the first beta of version 9.1 of the open source PostgreSQL database has opened a new era in enterprise-class reliability and data integrity that can compete with the big names, say its developers. CIO recently interviewed Josh Berkus, Kevin Grittner, Dimitri Fontaine and Robert Haas about PostgreSQL 9.1 and its future.

A petition launched in December by MySQL creator Michael 'Monty' Widenius to 'save' the open-source database from Oracle has quickly gained momentum, collecting nearly 17,000 signatures. Widenius on Monday submitted an initial batch of 14,174 signatures to the European Commission, which is conducting an antitrust review of Oracle's acquisition of Sun Microsystems, MySQL's current owner. The petition calls for authorities to block the merger unless Oracle agrees to one of three "solutions", including spinning off MySQL to a third party and releasing all past versions and subsequent editions for the next three years under the Apache 2.0 open-source license.

Database security is the single biggest concern with today's Web-based applications. Without control, you risk exposing sensitive information about your company or, worse yet, your valuable customers. In this article, learn about security measures you can take to protect your PostgreSQL database. Be sure to download the sample code listings used in this article.

Jeremy Zawodny takes a look at the state of MySQL. "Robust development from outside the Sun/MySQL sphere, new storage engines and the return of Monty are just some of the signs that MySQL is healthy, despite may reports to the contrary."

Fatal Exception's Neil McAllister questions the effect recent developments in the MySQL community will have on MySQL's future in the wake of Oracle's acquisition of Sun. Even before Oracle announced its buyout, there were signs of strain within the MySQL community, with key MySQL employees exiting and forks of the MySQL codebase arising, including Widenius' MariaDB.

Michael "Monty" Widenius, original author and founder of MySQL, has announced he has now resigned from Sun to start his own company, Monty Program Ab. Rumours of his departure had circulated last September and Widenius now confirms these had an element of truth to them. According to him, his issues with MySQL 5.1 GA were pivotal in the decision making process and his public warnings of those problems "had the wanted effect". That effect was an agreement to stay on for three months to "help Sun work out things in MySQL development" and allow Sun to "create an optimal role for me".

In an almost indiscernible and confusing article filled with various scientific terms that most cringe to hear, it was described how in October of 2008 scientists successfully stored and retrieved data on the nucleus of an atom-- and all for two short lived seconds. With this new type of storage, a traditional bit can now be both zero and one at the same time, but in order to understand just how this is possible, translate the article linked above to plain English. Data integrity returns after two seconds at 90% and storage is obviously impermanent, so there are many kinks to work out before atomic storage actually serves a purpose, but give these scientists a couple of decades, and it's theoretical that we'll one day have nuclear drives the size of USB drives today (or MicroSD cards, or why not even specs of dust?) that can hold hundreds of terabytes-- even pentabytes-- of information.

"So how is Oracle doing with its Oracle Unbreakable Linux? Pretty well. According to Monica Kumar, senior director Linux and open source product marketing at Oracle, there are now 2000 customers for Oracle's Linux. Those customers will now be getting a bonus from Oracle: free clustering software."

The Firebird RDBMS 2008 Roadmap is now publicly available. During this year, Firebird users can expect two final releases (2.1 and 2.5) and the first alpha of FB 3. Many new features are planned, as described in the roadmap. In addition, RC1 of 2.1 has been released.

"MySQL quietly let slip that it would no longer be distributing the MySQL Enterprise Server source as a tarball, not quite a year after the company announced a split between its paid and free versions. While the Enterprise Server code is still under the GNU General Public License, MySQL is making it harder for non-customers to access the source code."

"In a world of people obsessed by turning the tiniest idea into something profitable, Dr Richard Hipp's best-known software stands out for two reasons - he actively disclaims copyright in it; and at a time when multi-megabyte installations are booming, he has a self-imposed limit on the size of his product: 250KB. And he's stuck to both aims. 'I think we've got 15 kilobytes of spare space,' he says of the headroom left in the code."
