STUFF
• Some of you have emailed about the MP3 cutting out at 8:50-ish. We have re-encoded the MP3 and posted the file. Sorry for the inconvenience and enjoy the show.

• Build a PC with Loyd. Still scratching your head on the mysteries of assembling your very own PC? Fear not ExtremeTech's Loyd Case is here kicking off a series of "Build a PC" tutorials.
• WikiScanner is an awesome tool to finding out who has been editing what on Wikipedia. Find out who's been tinkering with what on Wikipedia
• Paranoid about the The Man tracking your web surfing habits? Then learn how Tor can help you surf anonymously.
• DoesMetroid Prime 3: Corruption have what it takes to be AAA FPS on Nintendo's Wii?
• Ty wrote in to ask about OpenDNS. He wanted to know what it is and what you do with it. In a nutshell OpenDNS replaces the standard DNS server address you normally receive from your ISP. The advantage is that OpenDNS often times works faster and filters malicious and harmful sites.
• Dan wanted to know if multi-tasking increased the probability of errors when burning DVDs or overly fragmented the hard drive. In both cases the worries are overstated. With advent of burn proofing technologies and more capable CPU's the issue of burning a disc while browsing the web is no longer an issue it once was. In terms of file fragmentation that is more of a function of file shuffling on your hard drive due to repeated deletes and writes leaving gaps and fragmented files across your drive than to your PC running more than one app at a time.

I downloaded your show @ ~150+KB/s.
Then I watched it, and checked out TOR.
I installed the TOR software bundle and configured my browser and tried downloading your show again.
This time my speed was ~ 10-20KB/s.
Yes, TOR just may slow down your connection.

I noticed it says "COPYRIGHT: Ziff Davis Media 2008" at the end of the credits. Are you considering this version of the show to be the 2008 model like they do for cars and trucks at the end of summer? ;-)

OK, so this anonymous browsing Tor system is for the paranoid, and works by people letting others browse through their IP addresses.

Paranoid Thought 1 - so someone out there modifies Tor code on their computer, and gets to see everything going through the system, and can do "Man in the middle" attacks automatically because they ARE the man in the middle.

Paranoid Thought 2 - people are doing things using my IP address. So what happens if there's a knock on the door and someone says that threats on the President, Congress, twelve schools, six businesses, and a nunnery all were sent from my IP address and I'm in big trouble?

Prioxy actually helps stop DNS leaks. It direct DNS requests through TOR instead of allow your computer to directly make the request.

@Donald Brown, regarding Paranoid Thought 1, TOR is fairly robust when it comes to man in the middle. The only node that can see what you're doing is the exit node, which can be changed with every request if desired. Data in a TOR packet is encrypted with the public key of the node that is suppose to see it. When a request is made the actual request data is encrypted with the exit node public key, the routing information for the previous node is append to the top of the encrypted data and the whole thing is encrypted with the key for the second node. Finally, routing information for the first node is append to the top and the whole thing is encrypted with the first nodes public key. The packet is built from the bottom up and encrypted each time like the layers of an onion, hence the onion router. As the packet moves the layer are stripped away. Each node only knows the node they got a packet from and where to send it, with the exception of the exit node which can see the actual user data. It's hard to ID the originator because a node doesn't know if the packet is just being relayed or if the previous node is the originator.

Comment on segments like the ¨Build a PC with Loyd¨. Keep it in the main show but also it would be good to take those and make a page on your site so you can just download the single segment by it self. Call it something like ¨dl.tv singles¨. Have the opening and closing credits like the normal show has with a ad stuck in the middle. You could do this also for the segments done by Alex Lindsay and the 1up people. It would make it easier to find old segments without having to go thru dozens of old shows. You could have a section for say console mods which would have the segments you guys did for the ¨xbox media center¨. I think this could help you guys leverage your old stuff.

Want to make a system admin angry? Run TOR on a network where they're also running web filtering software. When they notice, you'll get a nasty note if you're lucky or even an invitation to re-list your resume online.

Don't get me wrong - TOR is great - until the system admin notices. In my case - 30 minutes ;)

On the Wii friend codes: I love that you've posted that and my son and I are going to add you. However! I thought that it was like the DS where we have to add you AND you have to add us? Should we send you an e-mail with that?

Wii friend codes ARE like DS codes.
We can add your code all day, but you will never see any indication that anything happened.

You have to add our Wii code too.

It is a 2 way configuration because Nintendo only wants us talking to the online perverts that we have pre-approved :P

(If you haven't left a comment here before, you may need to be approved by the site owner before your comment will appear. Until then, it won't appear on the entry. Thanks for waiting.)
