Creating JDBC Connections Doesn't Have To Be Slow (or "not the reason to be using a pool")
Employee +4 Vote Up -0Vote Down

Hanging out in #mysql on freenode the other day, I overheard someone saying that the reason to use connection pools with MySQL is because JDBC connections are expensive to create. That is true out of the box, but mostly because the out of the box behavior of MySQL's JDBC driver is to be standards-compliant. If you know that your DBA and your developers aren't doing crazy things with the database (changing configurations without letting the developers know, going around the "standard" API calls to start/end transactions, etc), then you can get to the point where connection setup is no slower than any other API. Does this mean you shouldn't use a connection pool? NO! (more on this next week).

Here's an iterative overview of the changes made in configuration, and how they affect what queries the driver does on initialization.

First, asking the

On Password Strength
+6 Vote Up -0Vote Down
XKCD (as usual) makes a very good point – this time about password strength, and I reckon it’s something app developers need to consider urgently. Geeks can debate the exact amount of entropy, but that’s not really the issue: insisting on mixed upper/lower and/or non-alpha and/or numerical components to a user password does not really improve security, and definitely makes life more difficult for users. So basically, the functions that do a “is this a strong password” should seriously reconsider their approach, particularly if they’re used to have the app decide whether to accept the password as “good enough” at all. Update: Jeff Preshing has written an   [Read more...]
MariaDB now available as a hosted database via Jelastic cloud platform
+5 Vote Up -0Vote Down

About Jelastic:

Jelastic is the next generation of Java Platforms as a Service.

Unlike previous cloud platforms, Jelastic:

  • Can run any Java application and so does not require developers to change their code or get locked-into the platform,
  • Can scale any application up and down by automatically adding or removing memory and CPU units depending on the application load,
  • Takes all configuration and management worries away: developers simply specify the application stack and database options they need and Jelastic creates, configures, and maintains the environment for them
  • Supports a wide range of application server stacks including Tomcat, JBoss, Jetty, and GlassFish
  • Out of the box, allows users to get a preconfigured instance of MariaDB up and running and available to the application.

A beta

Developer Week in Review: Lion drops pre-installed MySQL
+1 Vote Up -1Vote Down


A busy week at Casa Turner, as the infamous Home Renovations of Doom wrap up, I finish the final chapters of "Developing Enterprise iOS Applications" (buy a copy for all your friends, it's a real page turner!), pack for two weeks of vacation with the family in California (Palm Springs in August, 120 degrees, woohoo!), and celebrate both a birthday and an anniversary.



But never fear, WIR fans, I'll continue to supply the news, even as my MacBook melts in the sun and the buzzards start to circle overhead.

The law of unintended consequences

If you decide to install Lion Server, you may notice something

Oracle at fisl12 (Porto Alegre, Brazil, 2011-06-29/2011-07-02)
Employee +1 Vote Up -0Vote Down

fisl12 is likely the largest free and open source software event in Latin America. This year, it takes place in Porto Alegre, Brazil, from June 29th to July 2nd. Oracle is a gold sponsor of the event and I will attend it as a speaker. I feel honoured and excited to be there – for me it will be the first visit to the South American continent.

They already have over 3000 registered attendees, so this definitely is going to be a great conference. There is quite a number of well-known names on the speaker roster and I look forward to meeting a lot of familar faces there.

Oracle at LinuxTag 2011 in Berlin, Germany
Employee +1 Vote Up -0Vote Down

Linuxtag is likely one of the oldest and largest Linux/OSS events in Germany. I remember having been there to represent SuSE Linux while it still took place at the University of Kaiserslautern, using tables and chairs from the lecture rooms as exhibition stands (this must have been around 1998 or 1999). This year it will take place in Berlin again, and the session schedule looks very promising. I'll be there from Wednesday till Friday and I feel that I will have a hard time deciding which presentations I should attend...

I'll be speaking about What's new in MySQL 5.5 on Friday, 13th of May, at 15:00. If you haven't updated to MySQL
