Question: I got a CD from a friend that has an ISO file on it. What do I do with it?
Answer: An ISO file is similar to a ZIP file.
Eddie: What’s a ZIP file?
David: A ZIP file is a file that acts like a folder and can hold several other files. This allows the entire collection of files to be transmitted as a single email attachment, for instance, and that’s the kind of thing they were designed for.
Eddie: OK, so a ZIP file is a container for other files.
David: Right. Just like a suitcase. You pack a suitcase, carry it wherever you’re going, then unpack it and wear the clothes. You have to take the contents out to use them. An ISO file is also a container file that holds all the sectors of a complete CD or DVD. It’s called an image file. One of my son’s friends, who asked this, was going to try Linux, an alternative to Windows, that came as an ISO file. The person who downloaded it for him, just burned the file to a disc. But that’s not quite what you do with an ISO if you want a working copy of the CD. Because it’s a kind of suitcase, you have to unpack it some way in order to use it. You need a program like Nero, Roxio, or any of several free programs that we’ll link to in the show notes, to “unpack that suitcase” onto a CD. When you do that, you’ll be able to use the CD to boot Linux and try it out.

Cool Gadget: Sony Cybershot T500. Sony’s Cybershot T500 Digital Camera is this week’s pick. It’s a point-and- shoot type camera that takes pictures at 10.1 megapixels. That’s nice, but that’s not the feature that landed it here. It’s got a 3.5-inch touch screen, but that’s not the feature that got it on the show. It has a 5x optical zoom, face detection, and in-camera photo retouching tools, but as cool as those features are, the one that I found most compelling, and the reason it’s on today’s show, is that it can also shoot 720-line HD video in widescreen 16:9 aspect ratio. For that matter, while shooting HD video, you can still take a few still pictures. Sony says one, but PCMag’s review says up to three. It has a docking station with an HDMI port so you can connect it to an HDTV to look at the pictures you’ve taken. This camera has numerous features, more than we have time to talk about now. The one thing about this camera that I don’t particularly care for is that even though the rest of the digital photography world seems to have adopted SD, or XD-Cards to store photos, this camera, like all Sony cameras, only supports Sony’s own, proprietary, Memory Stick, and Memory Stick DUO cards for photo and video storage.
It's All “Geek” To Me: P2P: P2P stands for Peer to Peer. Networked applications can be either Client-Server, or Peer to Peer. Bittorrent, Limewire, Kazaa, and some others are Peer-To-Peer. In a client-server network or application design, you have a dedicated server that stores files, media, whatever. But in a Peer to Peer design, you don’t have a centralized, dedicated server acting as a repository. Each computer is responsible for storing parts of the total. Now, while a peer to peer network in your home is not a problem, peer to peer networks like Limewire are a wonderful way to spread malware. In fact, the worst-infected computers I’ve worked on have Limewire or some other P2P software on them.
