If you don’t know Project Honey Pot, go and have a look. They offer a service for querying IP addresses and check if they are listed in those involving in spamming or threatening activities.

Self executing jar files

I personally always felt bad about the fact that we have to provide a shell script which runs the executable jar file. It would be nice if we could provide a self contained executable in a single file, right? I just discovered a trick which works on unix, but it can possibly be adapted on […]

Yesterday I noticed that when I close the lid of my MacBook Pro the light in front of the case was not indicating that the computer was going to sleep normally. Still the fans were running and when I opened the lid, I saw that it was not resuming from sleep properly, presenting a strange […]

The Azure Window, in Gozo Island, Malta, a photo by Luigi R. Viggiano on Flickr. New year, new life. Got my camera bag stolen with all the gears in my hometown Turin. Yesterday I was looking back to the old pictures, and I found some good ones made with a 10 year old super compact […]

After installing OS X Lion I tried to burn a DVD in my macbook, and it turns out that this is what I get using Disk Utility: I tried several DVDs (DVD+R, DVD-R, different brands, and tried to burn at different speed), with no luck. Also it refuses to read movie DVDs. But it can […]

This picture has been shot from the Rhein promenade in Düsseldorf. I remember I was having a bad day at home, so I went out for a photo walk, which extended to be till late evening. I come back with a lot of good shots. The sun was red and visible by bare eyes, and […]
