I have to say that Apache Solr is an amazing product. If you reached this post you probably run or heard about it before, if not head to http://lucene.apache.org/solr/ to read more about it. It's just wonderful to see what the open source community can achieve. 

For production systems it's often best to deploy code automatically from a source code versioning system, like Subversion or CVS, using Ant, Nant or whatever. But sometimes it's handy for a group of users to be able to upload files straight to a server from their own machines. This story is about how one can setup the appropriate permissions for a team who wants to upload files to an Ubuntu/Debian server using SFTP. This is tested on Ubuntu 8.0.4 LTS and using WinSCP as SFTP-client from a Windows XP.

Using the web standard compliance tests at acidtests.org one can check the how well different browser adhere to web standards.When running the Acid3 test the browser should render according to this reference. 

By using a program called rtmpdump it is possible to save a copy of streaming media that is using the rtmp protocol. rtmpdump was previously hosted at sourceforge, but after a removal request from Adobe it was removed. Instead you will find the source code at this place http://lkcl.net/rtmp/. This site contains the source code and links to mirror and torrent sites that host the code.

Download the latest version of rtmpdump, at this time of writing it is version 1.6 that is out.

I've got an old Dell Inspiron 1300 that is equipped with a Broadcom wifi that worked fine until I made an upgrade of the kernel recently. I believe it was when I switched to kernel 2.6.28-14 that something was messed up. The card worked alright but I could not authenticate against my wireless router anymore after the kernel upgrade. The thing is that all traffic between the client and the router is encrypted using WPA-PSK (Wi-Fi Protected Access Pre-Shared Key) and I suspect that it was here something failed, but I may be mistaken. Anyway this how I solved the problem. 

So finally, Google has officially announced that they will release their own OS. Not unexpected, but none the less very interesting.

At work we use Xerxes, a metasearch engine that relies on the Xserver shipper with ExLibris' Metalib. Xerxes is developed by David Walker at the California State University.

After a long wait Debian 5.0 aka Lenny has finally been released:

Äntligen så har ett program för hantering av BankID släppts för Linux! BankID används ju flitigt på flera sajter, inte minst för viktiga samhällstjänster som till exempel Försäkringskassan. Fram till nu så har Linuxanvändare varit förvisade till kylan och i praktiken varit tvungna att ha en alternativ Windows- eller Macinstallation för att kunna utföra sina ärenden. I denna genomgång så visar jag hur man går tillväga för att få det att fungera på Ubuntu 8.04 (den enda Linux-distributionen som i nuläget har officiell support).

This is just a note to myself so that I can cut and paste the snippet that generates a ChangeLog from a Subversion repository. To generate a ChangeLog in HTML from the last 14 days run this and save the resulting file in specific place and with a specific name:
