OnJava.com: Interview with Java Podcasters

OnJava.com have 2 interviews on their site this week with two people who regularly publish a Java/programming related podcast.

The first is with Dick Wall who co-hosts the Java Posse podcast, and the second is with Michael Levin who hosts the Swampcast.

I’ve listened to several episodes of the JavaPosse podcast asd it’s well worth a listen – they cover a wide range of Java related news stories and have people on for interviews. I haven’t heard the Swampcast yet, but will take a listen some time soon.

History of the Hard Drive – in pictures

News.com have a neat gallery of pictures showing the evolution of the hard drive.

The gallery has pictures ranging from the first hard drive, a 24″, 50 platter monster, which had a capacity of, wait for it, … 5MB, through the first mainframe harddrive that a single human could carry (in 1982), to 1″ microdrives from Hitachi. Interestingly, the 1″ microdrive appeared in 1999 but did not find a mass market until the iPod Mini just last year.
