In print: will the iPhone squash the Crazy Frog, where's Duke Nukem?, better fuel cells, and what Dark Side of the Moon sales tell us

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

• In depth:
  • Hanging up on ringtones
    With the market for downloadable over-the-air content flat, operators and music companies are looking to other ways of making money from mobiles, says Adam Webb.
  • Government on the back foot over policies for pricing data
    Free Our Data: Two government reports mark a move towards joined-up thinking - but there is some way to go, says Michael Cross.
  • For power, just add water
    Researchers have found a way to get renewable energy by extracting hydrogen from an alloy, reports Michael Pollitt.
  • Game developers suffering a fit of the vapours
    The latest Duke Nukem game is in its 10th year of development - but it's not the only long-delayed thing, says Alexander Gambotto-Burke.
  • Taxman lets loose the spiders to net Wimbledon rent cheatsWimbledon residents hoping to make a quick buck this fortnight by renting their property to tennis fans would be well advised not to advertise online if they want to keep the transaction private. HM Revenue and Customs is deploying a web spider to sniff out undeclared rentals and link them to tax returns, says Chris Partridge.
• Opinion:
  • Pointless iPhone speculation hides more important mobile matters
    Charles Arthur: Perhaps uniquely for a product that has not yet appeared on any retailers' shelves, the iPhone has set some sort of record for prerelease hype - and opprobrium.
  • Software companies are building their way to a very material future
    Nick Carr: Today's software companies are finding that, as more computing tasks move online, they have to compete not just on the elegance of their programs, but on their ingenuity and efficiency in buying and deploying physical assets.
  • The striptease of the vanities awaits us
    Victor Keegan: For years we have been worried stiff about a state-backed Big Brother using new technology to extract personal information about us, whether from the web or CCTV cameras. But now it has all changed.
  • Technobile
    Gordon MacKie: I know how to spell my surname, thanks, and I don't want software telling me otherwise.
  • A machine gun now comes with a lesson in philosophy
    Gamesblog: If your understanding of videogame culture has come solely from reading the newspapers this month you'd be forgiven for thinking that developers are, for the most part, irresponsible psychos with a target audience of demented murderers and heretics. In fact, these days, most violent games have a brain and, Lord help us, a conscience.
• Newly Asked Questions:
  • What will the future look like - utopian, dystopian, or both?
    An exercise organised by the Economic and Social Research Council (ESRC) to consider what sort of world advances in nanotechnology, genomics, information technology and cognitive science might create was a mix of Neal Stephenson and Bill Clinton - a cyberpunk novel written by policy wonks, says Kevin Anderson.
  • What do increased sales of Dark Side of The Moon tell us?
    That there's a new audio format to buy it in, says Charles Arthur. Pink Floyd's 1973 album has become the unofficial metric by which one measures a new audio format's likely takeup.
