NIST::NVD::Store::SQLite3

I published an SQLite3 storage back-end to NIST::NVD on the CPAN. It’s pretty quick. About as fast as the DB_File one, but without the down side of being tied to DB_File. It shouldn’t be too difficult to re-factor this code to any DBI-based database. MariaDB anyone?

I know it works on Debian. The nightly CPAN test results should come back shortly and I’ll find out how well it works on other platforms.

Time to vote for MySQL sessions at FOSDEM
There is a room dedicated to MySQL at FOSDEM 2012. (Thanks to @lefred for organizing). The CfP has received 37 submissions, but there will be time slots only for 12 to 15 talks. So now it's up to the community. If you want to attend a particular talk, you should vote for it. Like in previous years, the selection of the talks is public. You can see the list of the proposals, with the instructions, which I repeat here. You can vote either publicly, using Twitter, or privately, by sending an email. Each talk proposal will be referred by the number immediately after the title in this page. …

Could closed core prove a more robust model than open core?

When participating recently in a sprint held at Google to document four free software projects, I thought about what might have prompted Google to invest in this effort. Their willingness to provide a hotel, work space, and food for some thirty participants, along with staff support all week long, demonstrates their commitment to nurturing open source.

Google is one of several companies for which I'll coin the term "closed core." The code on which they build their business and make their money is secret. (And given the enormous infrastructure it takes to provide a search service, opening the source code wouldn't do much to stimulate competition, as I point out in a posting on O'Reilly's radar blog). But they depend on a huge range of free software, ranging from Linux …

Have you ever heard about “Read Masters” in MySQL??? Enterprise ready SchoonerSQL provides it.


Typical MySQL environment involves one Master receiving writes and multiple slaves to scale the reads. The “slave” term has been used in MySQL because the Slave servers have to perform every task in copying from the Master binlog, then updating their relay logs and finally committing to the Slave databases. The Master plays no role in replication here other than storing the replication events in the binlog.
With this kind of Master- Slave set up, there are several limitations-
-       Slave lag -       Stale or old data -       Data loss -       Manual failover which is error-prone and time consuming
In SchoonerSQL, there is no concept of “Slaves” inside synchronous cluster. We refer to it as "Read Masters" because of our synchronous approach and different replication architecture. It is …

Tungsten Replicator and MySQL Sandbox at Percona Live London 2011
I will be a speaker at Percona Live - London 2011, and I am looking forward to the event, which is packed with great content. A whopping 40 session of MySQL content, plus 3 keynotes and 14 tutorials. It's enough to keep every MySQL enthusiast busy. Continuent speakers will be particularly busy, as between me and Robert Hodges, we will be on stage four times on Tuesday, October 25th.

Wrap-up of 2011 MySQL Conference

Two themes emerged at this week's MySQL conference: Mix your relational database with less formal solutions and move to the cloud. Naturally, the event included many other talks of a more immediate practical nature: data warehousing and business intelligence, performance (both in MySQL configuration and in the environment, which includes the changes caused by replacing disks with Flash), how to scale up, and new features in both MySQL and its children. But everyone seemed to agree that MySQL does not stand alone.

The world of databases have changed both in scale and in use. As Baron Schwartz said in his broad-vision keynote, databases are starting to need to handle petabytes. And he criticized open source database options as having poorer performance than proprietary ones. As for use, the databases struggle to meet two types of requirements: requests from business users for …

What VMware's Cloud Foundry announcement is about

I chatted today about VMware's Cloud Foundry with Roger Bodamer, the EVP of products and technology at 10Gen. 10Gen's MongoDB is one of three back-ends (along with MySQL and Redis) supported from the start by Cloud Foundry.


If I understand Cloud Foundry and VMware's declared "Open PaaS" strategy, it should fill a gap in services. Suppose you are a developer who wants to loosen the bonds between your programs and the hardware they run on, for the sake of flexibility, fast ramp-up, or cost savings. Your choices are:

An IaaS (Infrastructure as a Service) product, which hands you an emulation of bare metal where you run an appliance (which you may need to build up yourself) combining an operating system, application, and related services such as DNS, firewall, and a …

VistA scenarios, and other controversies at the Open Source health care track

The history and accomplishments attributed to VistA, the Veterans
Administration's core administrative software, mark it as one of the
most impressive software projects in history. Still, lots of smart
people in the health care field deprecate VistA and cast doubt that it
could ever be widely adopted. Having spent some time with people on
both sides, I'll look at their arguments in this blog, and then
summarize other talks I heard today at the href="http://www.oscon.com/oscon2010">Open Source Convention
health care track.

Yesterday, as href="http://radar.oreilly.com/2010/07/day-one-of-the-health-care-it.html">I
described in my previous blog, we heard an overview of trends in
health care and its open source side in particular. Two open source
free software projects offering electronic health records were
presented, …
