This week's print edition of the Technology supplement is online too, with stories about the US Army's plans to have robots fighting for it, how pornographers want your domain, this week's gadgets, asking: has YouTube changed? and why are antivirus companies going at each other like cat and dog?, and looking at plastic guitars and much more..

• Launching a new kind of warfare
  Robot vehicles are increasingly taking a role on the battlefield - but their deployment raises moral and philosophical as well as technical questions, says Pete Warren.
• Why it matters to master your domain
  Let your registration lapse, and your site could suddenly be taken over by links to porn - and there's little you can do about it.
• Ordnance Survey in the dock again
  Map information is vital to retailers planning stores and products - but it comes at too high a cost.
• The playful approach to political debate
  Keith Stuart: In his Tate Britain lecture, Armando Iannucci argued that comedy shows provide the only real forum for political analysis. It's an interesting standpoint - but if he were to head over to sites like Watercoolergames.org he'd find a thriving new arena.
• Will Windows Vista ship on time?
  The deadline is a moveable feast, so it depends how you define "on time".
• Has YouTube changed since its purchase this month by Google?
  Perhaps you're thinking of the reports in the past week that YouTube has removed 29,549 video clips after being contacted by Japanese rightsholders who said it contained materials taken from Japanese music, movies or TV.
• The PC is dead, long live the mobile
  Victor Keegan: Consumer spending is showing signs of faltering in some major economies - but no one has told the mobile phone industry, which is now flying without wings.
• Technobile
  Kate Bevan: Why sign up for BT's new online vault service? It's far cheaper to archive your digital stuff yourself.

  Apple's co-founder, Steve Wozniak, came to the company through a series of 'little accidents' and insists that he remains an engineer at heart.
• DAB should be the new wave, not medium wave

• Going against the grain
  Clever use of polycarbonate could revolutionise the way guitars - usually made of wood - are manufactured.

• Gadgets
  • Motorola KRZR
    Motorola has struggled to come up with a worthy successor to the RAZR, arguably the most influential phone of the past few years. Its latest attempt is the KRZR, which has the same clamshell design but has some additional features.
  • Sony C1-VTNC1S

  • Saitek iFreedom
