Globalcode’s Casual Class: Robotics

Yesterday held the seventh edition of the Globalcode‘s Casual Class, this time featuring Robotics. Like before, this is a meeting that includes technology, pizza and beer! Can’t get much better than that =)

This time, the event was mainly presented by Vinicius Senger, Paulo (not me =p), and Alberto “Spock”. They talked a lot about robotics (of course) and electronics. Although I don’t think I will be using any of this information soon, it was very fun!

One of the biggest topics was Arduino, and “Open Source” Hardware. This is basically a controller board that you can build yourself at home, with very cheap components.

They also did some nice demonstrations, and explained how Arduino works, going a little bit in depth. I can’t say I understood too much here, but it certainly got me curious to find out more. I hope to find some time to at least play a little bit with some ideas. If it happens, I’ll post my discoveries here for sure!

For example, they showed the Egg-Painting robot running, which they had mentioned in the previous edition of the Casual Class.

SE-Radio

Quick post this time. Again, on the topic of podcasts, I’ll talk about one I listen to regularly.

Created by a german guy, SE-Radio is a great show targeted at software developers of any skill level and background. Also, they tend to be language agnostic, so developers of any kind can find useful and interesting content there.

It covers topics from agile to CMM, from Java to .NET and other topics like SQL and database stuff, software architecture, patterns…

I found this podcast by accident, when Tor Norbye mentioned it in one of the Java Posse episodes. Now, I’m trying to listen to every single episode – they have 140 episodes so far.

You can find SE-Radio here.


The Snitcher

The Snitcher is a new Open Source project we just made available at Kenai. It comes to help us solving a problem that occurs a lot occurs a lot to us: allowing users to easily submit bug reports. It is still not feature complete, but it is already possible for users to report bugs through the tool.

The way it works is very simple. You just have to deploy the application in any java application server. For now, there is just two boring steps that need to be done. The domain variable in the snitcher-loader.js script file, and the URL for the css file and for the form action in the snitcher.jsp file must be set to the correct values.

Then you add a simple <script> tag in your page, as follows:

<script type="text/javascript"
    src="{domain}/Snitcher/snitcher-loader.js">
</script>

Here, {domain} is the domain under which the application was deployed. This will load a small script, which will load Snitcher itself the first time a page try to display it.

To display the reporting window, you can attach a javascript function loaded in the previous script called toggleSnitcherOpen(element) to any onclick event you want, where element is the place in the page you want to store Snitcher – you can use something as simple as body).

After loading, this is how Snitcher should look (as of now, it is likely to change in the future):

Now, there is still a lot of work to be done. If you are interested in helping out, or just on keeping an eye on how the project goes, visit the project site at kenai.com/projects/snitcher. Also, take a look at the wiki for where exactly we are looking for help right now.

Finally, please let us know in the comments, e-mails or in the discussion list if you have any comments!
