Mobile phone tracking
I was thinking of a little project for myself ... is there a cheap (if not gimme the expensive one) way to track a mobile device in a area ? Like if i get some sort of devices to set up a radious in a feald and then i would be able to get the locations of a mobile phone (i know i would need 3 such devices or more for triangulation)
i just need to know if there is a way to do this without that person knowing (dont need additional software on the phone itself) so when someone with a mobile... Read more →

Any real reason to build your own PC any more?
Let's be clear: I love building my own computers. I've been doing it for more than 20 years and I won't stop any time soon. It used to be more cost effective. Then it was the only way to get certain high-end parts. But now? Now I just do it for fun and I justify it as part of my hobby time away from the family. Does anyone else have a better reason?

What are your preferred brands when building PCs?
I generally use Corsair or Sandisk for memory (SSD and RAM), Corsair for the PSU, CPU Cooler and chasis. As for GPU I generally go with nVidia as I have had bad experiences with AMD.

The PirateBox: DIY project for anonymous offline file sharing and chat
I just heard about the PirateBox, a really cool DIY project that uses off-the-shelf parts and open source software to create a private network with support for sharing files and communications via a simple message forum. It kind of reminds me of the old private bulletin board services way back in the day.
Anyway, it seems like something that could be useful for small neighborhoods or in places where Big Brother's watchful eye might inhibit the dissent. Some sort of... Read more →

Options for a "modern" KVM switch?
On my desk at home, I have one monitor, a keyboard, a mouse, and a decent set of speakers that are ultimately shared between 3 machines:
  • Windows 7 gaming PC
  • Mac mini for personal use
  • Macbook Pro work computer
Awhile ago, I purchased The-World's-Crappiest-KVM-Switch™. It was about $35, let me "switch" between 2 devices (more on that in a bit), had a few USB 2.0 ports, and your standard assortment of DVI connectors. Also, it was ugly -- it has so many cables coming out from every surface it looks... Read more →

Do you give your computer a name?
I've had a computer for over twenty years now, and I remember when it was de rigeur to always give your machine a nickname—maybe after your favorite sci-fi or cartoon character, or maybe even a beloved relative. Now we might replace our devices on a yearly basis, and it seems silly to give them names since, after all, why get sentimental about something that's going to be replaced in short time for something slightly better?
I don't replace my devices that often, though, and as I consider... Read more →
