Some days ago the Stanford University has published new and interesting podcasts about the iPhone/iPod programming. At the moment, the new podcasts are dedicated to Objective-C and related development tools. In addition to podcasts, the slides of the full lessons are available. Podcasts and slides can be downloaded from this link.

During the development of my last iPhone and iPod Touch application I had the necessity to work very much with threads. Looking for as much information as possible on Internet about the correct use of the NSThread class, I found an interesting tutorial (for beginners) which describes how to use the NSThread class to develop a small iPhone application. You can find the tutorial following this link.

Mounting an ISO image on Mac OSX does not require specific or additional software. Mac OSX, in fact, provides a tool (hdiutil) by which it is possible to manipulate disk images. For example, to mount an ISO image on Mac OSX, open your Terminal and enter the following command:

hdiutil mount /path/to/isoImage

/path/to/isoImage is the path to the ISO image to mount. After a few seconds, or better, after the checksum is completed, the mounted ISO image will appear on your Desktop and/or in Finder. For more information about hdiutil, enter the following command (in Terminal): man hdiutil.

cat /etc/passwd | cut -d ":" -f1

Mac OSX’s Finder by default does not show hidden files and folders and in the OSX menu ther is no option to enable this feature. I have just published a new tutorial which shows how to enable the visualization of hidden files and folders in Mac OSX’s Finder.

I have just edited my personal website updating the list of the scientific papers published during this year (until now).
