Crime preventing skirt

In Japan women are attempting to stop being victims of crime by hiding from their pursuers in plain site. They wear a skirt that turns into a full size cloth vending machine!







Hopefully they don't avoid one criminal only to find another breaking into vending machines. Original story at the New York Times .

New Linux Router

As some of you know I moved this year to a new house. I now have plenty of room in the garage for the servers which means my heating bill will go up now that they won't be contributing. Frown

Anyway I'd been using Powerline networking for some time and it's worked wonderfully because you never need drivers for the network. How it works is you plug your network cable into a powerline bridge and then plug the bridge into the electrical wall socket. Do this for each location and you have an instant network! It's completely painless. Only problem is your electrical wiring needs to be perfect and mine to the garage in the new place isn't. My print speeds were so horrible that I was copying data to my laptop and carrying it down there to print. It doesn't take a genius to figure out that isn't the solution. I've always shied away from wireless outside of occasional use on the road because of the security implementations but it appears I have no choice short of rewiring my house.

The new 802.11n stuff is tempting but without more testing I'm not going to bite. I already have a Linux powered Linksys WRT-54g which has served me well. My plan was not to add wireless cards to all the machines in the garage but rather set up a wireless bridge and plug a Gig switch into it so the servers could talk to each other at 1000Gbits and the rest of the world at 54Mbits. My biggest requirementis the router has to support the Linux DD-WRT software. After some looking I settled on the Buffalo WHR-G125  available for $29 at Circuit City with rebate...

The Buffalo WHR-G125 does not come with Linux installed and from what I saw on the review forums doesn't come with much functionality in the stock firmware either. I honestly didn't even log into the stock firmware or use it in it's stock form. The first time it was ever powered on I nailed it with a tftp upload with new Linux DD-WRT firmware and it's been running Linux ever since.

The Buffalo WRT-G125 is a 240 mhz mips processor (Broadcom BCM5354) embedded device with a 5 port switch and uplink. It has 16 megs of ram and with Linux running there's about 14 free. The antennae is fixed but I found one guy solder a connection on so he could connect any external antennae.



If you don't know what dd-wrt is you're in for a treat. It's a replacement firmware operating system for many consumer based routers. It gained it's fame on the Linksys WRT-54 series and that's where I came into contact with it. The Linksys WRT-54g was a Linux router and several firmware replacement projects stemmed from it. I started using a paid for replacement called Talisman. The firmware was encoded and I lost the original file once and didn't want to go through the hassle of getting the author to give me another so I decided to look around and see what else was out there. Well, that and there was a lot of controversy about the developer's practice of stealing other people's code and then acting like a copywrite Nazi when anyone else wanted his code. I don't like supporting people like that so I switched to dd-wrt. DD-WRT adds many features to your router like ssh access, QOS, wireless bridging etc.. There really isn't any reason that I can think of for not using it.

Thomas Jefferson's view on Intellectual Property Rights

I just ran across this quote of possibly this country's smartest founding father - Thomas Jefferson. It concerns copy writes and patents.

If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it. Its peculiar character, too, is that no one possesses the less, because every other possesses the whole of it. He who receives an idea from me, receives instruction himself without lessening mine; as he who lights his taper at mine, receives light without darkening me.

That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property.

Interestingly he believed that as soon as you released an idea of your own it belongs to everyone. Much in the way the GPL lays it down.
