Pain at a distance, Apple and its Wi-Fi, eBooks on the march, and much more

This week's print edition of the Technology supplement is online too..

• Targeting the pain business
  US-based Raytheon is marketing microwave weapon systems that 'fill the gap between shout and shoot'. But who will use them and why, ask Steve Wright and Charles Arthur.

• Newly Asked Questions
  • Did hackers find a weakness in Apple's Wi-Fi drivers?
    In theory, yes. In practice, it's very unclear, and has turned into an online cause celebre ranging two security experts, David Maynor and Johnny "Cache" Ellch, against pretty much the whole of Mac-dom, including high-profile Apple enthusiasts and Apple Computer itself.
  • Is my laptop's battery going to be recalled?
    Perhaps, but only if your laptop comes from Dell, Lenovo, Toshiba, Fujitsu or Apple. Which covers almost all the main portable manufacturers except HP and, oddly, Sony.
• Who will lobby for our right to copy?
  Victor Keegan: I recently committed a crime: I copied a CD I had bought on to my hard disk.
• Technobile
  Matt Dunn: Watching TV bounced over the internet is a nifty idea, but not if you plan to watch live sports.
• What happened after they killed the butler
  Ask.com, formerly Ask Jeeves, ranks fourth in the search engine stakes with about 5% of the market. It was bought in 2005 for $2.3bn by Barry Diller's IAC. Kate Bulkley talks to CEO Jim Lanzone.
