Cron and File Extensions

I created a script using TAR to backup my data on Ubuntu.
The script was putted to /etc/cron.daily but I didn't run!
After some investigations I found out that in /etc/cron.*/ directories no file extension or dots in the file name are allowed.

So be careful how you name your scripts that should run with cron.

OpenWebBeans Bootstrap in Java SE

It took me a while to get OpenWebBeans in Java SE up and running. Find below an example on how to bootstrap OWB:

ContainerLifecycle lifecycle = WebBeansContext.currentInstance().getService(ContainerLifecycle.class);

BeanManager beanManager = lifecycle.getBeanManager();
Bean<?> bean = beanManager.getBeans(B.class).iterator().next();

B b = (B) lifecycle.getBeanManager().getReference(bean, B.class, beanManager.createCreationalContext(bean));

jtoggl a Java API for Toggl

Toggl is a great tool for time tracking. Specially if you work for multiple clients and/or projects at the same time.

Toggl provides a REST/JSON API and several samples in various programming languages. But one thing was missing a Java wrapper for the Toggl API.

So I decided to create one. You can find the project on Google code. It's called jtoggl.

If you have any suggestions or find any problems please let me know. You can use the issue tracker.

PASV FTP with IIS 6 on Windows Server 2003

After some hours I finally get PASV FTP up and running on Windows Server 2003.
Here how to do it:

First set the port range:
C:\Inetpub\AdminScripts\adsutil.vbs set /MSFTPSVC/PassivePortRange "5500-5550"

Then open the port range to the firewall

Finally reset the IIS

That's all. Easy, isn't it ;-)
