The second Ruby on Beers happened yesterday. About 15 of us appeared, much more than I expected.
We were talking about Heroku, Git and Watir.
We did not have the time to talk about Unicode and RSpec, so we will talk about it the next time. There was interest in talking about Rubinius.
The next Ruby on Beers will probably happen at the same place (Multimedijalni institut, net.kulturni klub mama, Preradovićeva 18, Zagreb), at Saturday May 31st 2008 at 5 pm.

Yesterday I saw Webscale Computing presentation held by Mike Culver from amazon.com. I forgot to take my camera, so there are no photos.
I saw something that I could not get out of my head since. Amazon Elastic Compute Cloud (EC2). In short, rent Linux machines $.10/hour (hour is the smallest time unit).
I could use this for testing. I could really use this.
At the moment I test with one machine that has enough CPU and RAM to open one VMware image with application I test running inside. I have six independent test suites for the application, and it takes about an hour to run them all sequentially inside the image.
I could speed it up. I could rent 6 machines and run all tests in about 10 minutes. Since I must pay for the whole hour, it would cost me about $.60. I am not in such a hurry every day, but there are days where such speed in executing tests would make a difference.
The only problem is that my application and my tests run on Windows. But since it is VMware image, I can run it on Linux.
Now, let me day dream for just a minute.
Amazon starts to bill by the minute (or second). While I am dreaming, they also lower the prices. I fragment my test suites, so every takes about a minute (or less). I could rent as many machines I need and be done with testing in an minute. Of course, it is all done automatically. Every time a developer commits new code, a machine is automatically rented, set up for testing, multiplied (so I do not have to spend time powering up, getting new application code, building it, getting new test code…).
I will really have to check this out in detail.

The first Ruby on Beers meeting happened last Saturday, April 5th, 2008 at lake Jarun, Zagreb, Croatia (map).
Ruby on Beers is informal gathering of Ruby users. It all started at ruby-hr Google group (in Croatian) that came to life after the first BarCamp Zagreb where we realized that there are more than one Ruby user in the near (as I thought before Barcamp).
The four of us appeared. Branimir Šloser, Saša Branković, Mislav Marohnić and me.
We enjoyed excellent Tomislav beer and discussed the meaning of life, the universe, and everything, and more specifically, what to do next.
The next meeting should be on Saturday, May 10th, 2008. I hope I will be able to talk about Watir, and there are rumors that there will be something said about Git and Unicode. Only the time will tell.
More details at Ruby on Beers official page.
