There are some basic, golden rules when it comes to having a vibrant community of contributors.

The following are rules I have extracted and learned based on my experience managing and working with engineers actively involved and participating in the Apache/Derby, PostgreSQL and MySQL open-source communities. These rules are also based on extensive discussions with many folks involved with the MySQL community, with the PostgreSQL community and with the Apache/Derby (Java DB) community, over many years.

Before I go through these rules, I would like to thank Marten Mickos for having suggested some of the headings for these rules. (I originally had much longer headings for all of them.) I would also like to thank many of MySQL, PostgreSQL and Java DB colleagues, as well as to many other colleagues involved in open-source development, for having contributed to the ideas and practices behind these rules.

Sun reports second quarter results. Compiere reports 216% quarterly revenue growth. EnterpriseDB grows customers accounts. Hyperic and JasperSoft team up on BI for IT. Microsoft embraces Apache but resists GPL. And more.

Sun up or Sun down?
There was some comparatively good news from Sun, which reported a net loss of $209m on revenue down 10.9% at $3.2bn. As Sam Diaz at ZDnet notes, however, “after excluding one-time costs related to recent layoffs and other costs, the company posted a profit of 15 cents per share, beating analysts’ expectations of a 10 cent loss”. In regular trading, shares of Sun were up more than 5%.

Back in October last year a corporate accountability group called As You Sow attempted to persuade Oracle to detail its commitment to open source by publishing an Open Source Social Responsibility Report.

Oracle resisted the proposal but did promise to share more details on its use of open source in the next version of its Oracle’s Commitment social responsibility report. I just noticed that the renamed Oracle Corporate Citizenship Report (Pdf) was recently published (in late November as far as I can make out) and does indeed include a section on Oracle’s commitment to open source.

In the section “Open Source and Accessibility” Oracle notes that …

Today I ran into an issue which I could not figure out for quite a while. I was trying to redirect a url to another url using RewriteRule. It was supposed to be a pretty straightforward redirect which made it even more annoying than complicated ones. Hopefully somebody is able to explain what I am missing here and if my solution is a good solution or not.

I needed to redirect a url:  http://www.example.com/testpage.php?foo=bar to http://www.example.com/

So I added this to .htaccess file:

RewriteRule ^testpage\.php / [R=301,L]

This did do a 301 redirect as I wanted but query string passed so my redirected url looked like:  http://www.example.com/?foo=bar

Obviously this is not what I wanted so in order for me to fix it, I had to take a rather lame approach.  My new redirect is:

RewriteRule ^testpage\.php /? [R=301,L]

VentureBeat and OStatic are among the news source reporting the launch of Cloudera a new vendor set up to provide support for Apache Hadoop and related projects.

Given the current economic outlook it’s great to see a new open source start-up rearing its head, and the list of founders indicates that this one has a good chance of survival. While VentureBeat is focused on the fact that Ex-Google, Yahoo, and Facebook employees are on the team, my eye was caught by the fact that Mike Oslon, Sleepycat Software founder and former CEO has been tempted out of semi-retirement.

Here's a question I posted to the DBI as well as mod_perl mailing list that I thought would be also a good question to ask here:

Hi all,

I'm currently working on... of all things, a book on book about web app programming with Perl/Apache/MySQL, and I'm trying to explain what Ubuntu packages to use for installation (and I'm sure other Linux variants same applies)

Ubuntu gives you:

apache2-mpm-prefork
apache2-prefork-dev
apache2-mpm-worker
apache2-threaded-dev

I've used both prefork and worker (as of late, due to concerns with perl and threads), both of which seem to work fine. Though, the DBI documentation warns of caveats of using threaded, especially if the client is not thread safe (I always compile mysql with a thread-safe client, and DBD::mysql against that thread safe client).

So... I'm trying to decide if I should explain
