New Sun Contributor Signatories for MySQL

I just checked the "Sun Contributor Agreement" (SCA) signatories list, and there are already 11 people who have signed the contributor agreement with an intent to contribute to MySQL.

Among the signatories, you will also notice Paul McCullagh of PrimeBase/PBXT fame. (To learn about how to submit your SCA paperwork, see here.)

Signing the SCA with an intent to contribute to any given Sun-sponsored open-source project would also suffice when it comes to contributing to any other Sun-sponsored open-source project.

So, as an example, Nils Goroll is both an OpenSolaris and MySQL contributor. (See Nils' OpenSolaris profile and see MySQL bug id 7417.)

Of course, it goes without saying that you do not need to be an OpenSolaris contributor to be a MySQL contributor. My intent here was simply to show how signing the SCA helps the contributor to reach out, interact and contribute w.r.t. any Sun-sponsored projects. The SCA signatories list, of course, makes all of this much more plain.

Vibration Effects on Discs

This video, which I originally found on Jonathan Schwartz's blog, demonstrates, in a laboratory "study," how vibration on discs can be detected by D-Trace instrumentation in FISHworks (FISH stands for Fully Integrated Software and Hardware). The lesson: Don't Shout at Your Discs!

Wikipedia on Sun | MySQL Servers

Wikimedia Foundation is expanding Wikipedia to multimedia with Sun Open Storage Solution and MySQL Database:

Wikipedia receives between 25,000 and 60,000 page requests per second, depending on the time of day. Wikimedia needed to update its infrastructure to handle this huge volume of traffic and ensure that its systems were reliable, highly available, and easily scalable. It also wanted to expand its upload file limit from 20 MB to 100 MB to accommodate rich media (audio and video) content, but before it could do that it needed to expand its storage capacity.

It is great to see that how the most important non-profit content provider on the web grows and it is great to be part of that growth.

Wikipedia should be the subject of extensive studies in various fields of sociology, economics and information systems: social knowledge, open-source, open-content, markets, information economics and open-scoeity.

ERP and CMS on PostgreSQL on OpenSolaris

Jignesh K. Shah and Robert Lor describe how to set up Openbravo (an open-source ERP system) and Drupal (an open-source CMS) on PostgreSQL on OpenSolaris.

PostgreSQL BuildFarm on Solaris on Sparc

Check out a new PostgreSQL buildfarm set up by Zdenek Kotala. (By the PostgreSQL community convention, I'm referring to it as a "buildfarm" but it should probably be better known as a "testfarm".)

LinuxWorld Expo?

I dropped by "LinuxWorld Expo" in San Francisco on Tuesday, and I think the only thing worth noting is the PgDay.

Five years ago, when I attended the same Expo, it had a completely different spirit, with a lot more participation by the main Linux vendors and a large variety of software companies.

(Other references: PostgreSQL on Solaris and on OpenSolaris.)

DTrace Envy

A colleague in our PostgreSQL team just pointed me to a "little" note on DTrace, which seems to be ignited by the work that Robert Lor and Jignesh Shah have been doing. (The PG presentation involving the Mac OS and DTrace is Robert's)

Tolven Health PostgreSQL Benchmark

Tolven Health has published a benchmarking study with PostgreSQL on Solaris. The purpose of the study was to "to assess the scalability and performance characteristics of the Tolven open source healthcare information technology solution and to provide guidance for customers with regards to hardware requirements for enterprise, state, regional, and country wide deployments."

Open Source Databases on the Rise

Christopher Lawton of The Wall Street Journal reports on the rise of the open source databases:

The potential benefits in cost and flexibility have not been lost on customers. The market for open-source databases is expected to grow 35% to $270 million this year from $200 million in 2007, according to Gartner Inc. Among the earliest adopters are midsized companies, which don't always need the high-end features of conventional databases, says Carl Olofson, analyst with IDC, a market-research firm.

For example, Sun Microsystems Inc. provides supported offerings of MySQL, PostgreSQL and Java DB (Apache / Derby) to its customers.

If you're interested in discussion and community around open source database technologies for Solaris, see here.

OSDB Events

The best way to learn about major open source databases (e.g. MySQL, PostgreSQL, etc.) is to attend developer and user conferences. Sun Microsystems sponsors many of these conferences and events. (This April, you can catch Sun folks attending the MySQL conference in Santa Clara, and in May, you can catch them at PGCon in Ottawa.) Finally, if you're interested in Sun technologies and databases, you should become a member of the OpenSolaris Databases Community and start contributing.

PostgreSQL 8.3 is Released

Josh Berkus has just announced the release of PostgreSQL 8.3.

Bjorn Munch has posted a note on the release of the Solaris binaries for PostgreSQL 8.3 on the OpenSolaris database community discussion forum.

Munch also has a wiki entry that describes how to build PostgreSQL for youself. (Important note: As should be expected, Sun provides support only for PostgreSQL versions that it itself ships with Solaris. While this should be kept in mind, we also like developers to know how to build and develop PostgreSQL on Solaris. Hence the wiki entry!)

This, I believe, is the first time official Solaris binaries of a GA release of PostgreSQL become available also through PostgreSQL.org.

About this release, there has been a lot of commentary in the press and in blogsphere. These were forwarded by a colleague. I selected some of the news and blog items below, giving the relevant links:


If interested, you should also consult the official PostgreSQL 8.3 release announcement.

Finally, I would also recommend checking out Sun PostgreSQL web site and the OpenSolaris database community for discussion and other topics related to PostgreSQL and databases in general!

Data History

Meeting in Menlo Park (2006)

I took this picture in 2006 near the Sun MPK Cafeteria.

I find it historically interesting!

The Friendly Elephant and the Rising Elephine

Amol Chiplunkar describes his experience migrating an application to PostgreSQL. Here's how he describes the server requirements met by PostgreSQL.

Courtesy of Petr Zahradnik

The product has a central server layer that collects data from tens or sometimes hundreds of systems periodically. The collected data needs to be processed and stored in the database for generating reports and graphs. The data retainment policy is to keep on rolling it up so that the data stays over a long duration at a gradually reducing granularity level with time. Which means the freshly collected data should be the most granular while the older data should be summarized over a period of time and purged out as and when required.

In the meantime, Bjorn Munch describes how to build PostgreSQL for Open Solaris ... and Zdenek Kotala presents the "rising elephine" ...

Blogging from Berkeley

Blogging from Berkeley, David Van Couvering, a database technologist at Sun Microsystems, has recently written some pieces examining PostgreSQL on Solaris. (I certainly look forward to even more such pieces, or maybe some pieces on migration from Oracle or MySQL. I think there are some interesting topics to explore in those areas when it comes to tooling.)

For example, take a look at his posts on "NetBeans, Ruby on Rails, and PostgreSQL on Solaris"and on "Starting PostgreSQL as a service in Solaris Express ."

With revamped product web pages, you can more readily find information about PostgreSQL on Solaris, and if you're already a user of PostgreSQL on Solaris, you can buy PostgreSQL support from Sun.
