Nestoria Interview
Ed Freyfogle from Nestoria posted an interview with me on the Nestoria UK blog. We met up at the first ScaleCamp UK a few weeks ago. Thanks Ed!
Watching InfoQ presentations offline
For some time, InfoQ has published lots of great presentations from conferences and other talks. They post the video with slides and sometimes a transcript as well. Since I've been traveling a lot lately and seem to spend endless hours in airports, trains, cars, etc. I found that I saved up all my watching for outside of work. However because all of the presentations are streamed through a Flash player you must be online to watch them.
At the request of InfoQ, I have removed the bulk of this post. Without InfoQ, sponsors and of course the great presenters, none of this would be available. I would certainly not want anything to do with that stopping! Grab the mp3's that InfoQ have already started to make available, go to the conferences, and be a happy engineer!
EPEL repository
For some completely bizarre reason operations decided to go with CentOS for all future servers and releases. So as a good little soldier, I built up my new VM with CentOS 5. Why can't it just be easy from there on out?
yum install erlang
No go. Turns out there are a whole bunch of RPMs not in the official repository. In comes EPEL (Extra Packages for Enterprise Linux). EPEL is a "volunteer-based community effort from the Fedora project to create a repository of high-quality add-on packages ".
rpm -Uvh http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
yum install erlang
Check.
yum install rabbitmq-server
Check. Happy days.
ScaleCamp UK 2009 slides
ScaleCamp UK 2009 yesterday was a blast. Tons of good people, good talks and certainly worth while. Being a bar camp style event, everyone was able to volunteer to run a session. Here are the slides from the talk I did. Thankfully I think it went alright. Definitely next time will have less slides, more talking!
Download Maven artifacts
Ever wanted to download Maven artifacts from a repository without needing Maven? The biggest problem is how to handle Snapshot artifacts since there can be many per version. Here's a quick couple commands to do just that.
wget -P http://#{repository_base}/#{repository_path_part}/#{artifact_path}/#{version}"
grep -o '>\(.\)\+.war<' index.html | awk '{ print substr($0, 2, length($0) - 2) }' | tail -n 1 The key thing to notice is that it's grabbing the latest war from a particular, known groupId, artifactId and version.I hacked this into a Websitrano deployment which can now deploy to a cluster of Tomcats. One button deploys from a Maven repository
