Hardware Hacking

An anonymous reader writes "Using radio to eavesdrop on CRTs has been around since the 80s, but Cambridge University researchers have shown laptops and flat-panel displays are vulnerable too. Using basic radio equipment and an FPGA board totalling less than $2,000 you it was possible to read text from a laptop three offices away. This is certainly cool, but is this a security issue we should worry about?"

We support a small subset of HTML, namely these tags:

  • ul
  • li
  • dl
  • dt
  • dd

"ecode" can be used for code snippets, for example:
