The development team of popular open-source blog-software Wordpress just released the security update 2.6.2. It is highly recommended to install the update to eliminate some security issues within the Wordpress installation - especially for blogs with open registration.

The update fixes a security issue caused by the weak implementation of the php function mt_rand() in many popular php-distributions. The function is used for seeding the random number generator. It also addresses the security risk of MySQL and SQL column truncation vulnerabilities. Stefan Esser reported both security-issues which are probably relevant to a lot of other php-based open-source projects. Thanks, Stefan!

Beside the fix of security issues, the Wordpress version 2.6.2 also implements some minor bugfixes. Therefor the upgrade to the newest version of WP is highly recommendet to everybody using Wordpress.

Pratik Naik from the Rails core team just published the announcement for a new Ruby on Rails hackfest: The person with the most patches merged into the core at the end of the month wins. In August, O’Reilly will handout a free pass to the RailsConf Europe. Keep on coding!

From Sept. 2nd to Sept. 4th 2008 the Ruby on Rails community will meet at the RailsConf Europe. It’s the third RailsConf in Europe and it will located in Berlin/Germany again. Last year, more than 800 Rails enthusiasts joined the conference - a great developer community event - and always the chance to drink your coffee besides one of the creative minds of the Rails Core team There is nothing that can replace the face-to-face communication within the community. So, I can warmly recommend joining the conference in Berlin to every Rails developer who is able to get there. And all those, who want to develop elegant web applications and do not work with Ruby on Rails yet - they should join us more than ever.
But there is an other group I miss a lot on Ruby on Rails conferences: Designers. Why? Because great application and interaction design and good web-application usability can only be achieved if developers and designers work closely together. That is why developers need to know something about design and designers need to know something about development.

So, I’m really happy that my  proposal, focussing on that issue, was accepted at the conference. In my double role as a designer and developer I’ll talk about

DESIGN ON RAILS FOR USABILITY … Or why designers should start to understand code and developers should start to sketch and use design methods.

I’m really glad be a part of the conferece in September - and to meet all these interesting people - and hopefully some codedifferent-blogreaders, too And please don’t forget to join Bratwurst-on-Rails on the evening before the conference starts.

The berlin Ruby User Group put their shoulders to the wheel for the Ruby-on-Rails-community: At the Kalkscheune, nearby the conference location of the RailsConf Europe 2008 they invite all Ruby-on-Rails-freaks to a socializing and networking event.

Last year it was a great and fun event - you’ll finde some pictures at Flickr. A great developer community shoud know how to party - and there is one thing I know for shure: Yes, we can

So, for all Ruby-on-Rails enthusiasts, who are in Berlin on the first of September – one day before the RailsConf Europe starts: Sign up for Bratwurst-on-Rails! See you there!

By now: Warm thanks in advance to the Ruby User Group Berlin for organizing this event!

I just wanted to share the steps to upgrade an Ubuntu server running on 7.10 (Gutsy Gibbon) to the new version 8.04 LTS (Hardy Heron). The “official upgrade path” explained at Ubuntu did not work for me - and maybe some other of you also run into the same problems Read the rest of this entry »
