PC speakers also pick up radio
Jon Godfrey likes internet radio stations, but he can hear music coming faintly from his PC speakers whether he is connected to the internet or not I have had a Dell Dimension 8250 for several years, and I have connected to it a set of speakers through which I listen to the radio whilst online. I am receiving a faint but audible music channel, which I can hear whether I am connected to the net or not. Jon Godfrey This seems to be a common example (to judge by a Google search) of radio frequency interference or RFI, though it's not something I've heard on a PC. The speaker wires may be acting as an aerial and picking up a radio signal, which you then hear from the speakers. The loudspeakers may also be implicated: some models seem to have better shielding than others. You could try moving the speaker and mains cables, and folding up (rather than coiling up) any spare bits of wire, or changing to shorter, better-quality shielded speaker cables. If that doesn't work, try adding some ferrite rings to the speaker and mains cables. KSL Consulting has a web page, Solving Radio Interference (RFI) on Computer Speakers , which says: "Bunching the cables with cable ties to reduce their length will reduce the interference, as will winding each speaker cable around ferrite rings (winding at least 10 to 15 turns around the ferrite ring). The ferrite rings act as RFI filters, making the cables inefficient aerials. This reduces the level of the radio signal on the amplifier wiring. Ferrite rings can be purchased from Maplin.co.uk under stock code QT26D ." Maplin and similar stores also supply clip-on ferrites and shielded cables . Note that Cat5 Ethernet cables can also act as aerials and deliver a radio signal to the PC motherboard. Ferrite rings are a cheap solution, if they work. Upgrading the speakers is a more expensive option. America's Federal Communications Commission (FCC) published the useful Interference to Home Electronic Entertainment Equipment Handbook , which you can find online "preserved by KYES TV"

Pass notes No 2,738: the millennium bug
Ten years after the millennium bug scare, there's a new computer glitch hitting users of Sony's PlayStation games consoles Age: 10. Appearance: Surprisingly youthful. You do realise the millennium bug is old news? The clue's in the name. Yes, yes, but it's back! And this time it has come for our children! What are you on about? Remember how a decade ago the bug nearly destroyed civilisation? Planes were going to fall out of the sky, nuclear power stations were going to melt down, clock radios were going to wake us in the middle of the night . . . Unless we paid trillions of pounds to IT specialists . . . That's right. And all because other IT specialists had sold us computers that couldn't handle the switch from 1999 to 2000. That's the kind of organised blackmail even a banker could admire. Still, what has it got to do with 2010, especially now we're several months into it? Something very similar has hit Sony's PlayStation games consoles. On Monday, when February turned into March, millions of PS3 owners had their machines' calendars reset to 1 January 2000, and lost their high scores. Oh, the humanity! Have they been offered counselling?

Imogen Heap: ‘Don’t blame the machines, it’s not their fault’
Why singer Imogen Heap wants to make electricity out of horse manure What's your favourite piece of technology, and how has it improved your life? I was going to say Macs, but everyone says that, so I'm going to go into geek mode. I have these wireless wrist microphones that I wear on stage – they are throat mics that I've adapted. The audio gets picked up and goes into my computer. What's great about them is that I can wander about on stage and grab any instrument – like the wine glasses I use – and the mics are in the perfect position to pick up the sound. They've completely transformed me on stage. When was the last time you used them

Sir Clive Sinclair: "I don’t use a computer at all"
The entrepreneur and innovator tells Simon Garfield about inspiration, determination and why he doesn't do email… Thirty years ago this month, Clive Sinclair launched a computer that he hoped would change the world. In the majority of cases it only changed the way people played primitive computer games, but it also turned a bespectacled, prematurely balding man into a hero for our times. In those dark days before Windows 7 and the iPad, the Sinclair ZX80 represented the pinnacle of affordable domestic computing. It was a flat box without a screen or proper keyboard, it had the memory of a hamster and at the back of it was something that looked like a radiator grille but was actually a strip of plastic designed to look like a radiator grille. It promised it could do "quite literally anything, from playing chess to running a power station", which was good value for something costing £79.95 in kit form and £99.95 assembled, about one fifth of the price of other home computers. Sir Clive, who was knighted for services to industry at the age of 43, will be 70 later this year. He lives in an apartment overlooking Trafalgar Square, and from his adjacent office he has a magnificent view of tourists and lions (recently he also had a view of people performing on Antony Gormley's fourth plinth, but that "got a bit boring really"). He was a household name before Sir Alan Sugar, and for a while was the unlikely future of modern electronics: a bright, hi-tech uncle rejuvenating British industry blighted by decay, unions and Thatcher. Sinclair helped transform Cambridge into the computing capital of the world, a homegrown version of Silicon Valley and Taipei, and for a couple of brilliant years he made the bestselling computers in the world

Lenovo ThinkPad X100e | Technophile
The ThinkPad X100e has both good and bad points, depending on whether you see it as an overpriced netbook or a cut-price ThinkPad business notebook The IBM ThinkPad became the industry's premier notebook brand after the launch of the 700T in 1992, and its distinctive black styling and red TrackPoint became a noticeable part of business travel. ThinkPads were never cheap, but they were very durable, had outstanding keyboards, and you could get support and spare parts almost anywhere. Prices came down after China's Lenovo took over IBM's PC division, but the brand has managed to retain most of its value. I've been carrying ThinkPads everywhere for more than a decade, so I was delighted to see the Lenovo ThinkPad X100e when it appeared at the Consumer Electronics Show in Las Vegas in January. It was almost love at first sight. After using one (Type 2876), I'm less impressed, and my views might have tipped too far the other way. The main problem with the X100e is trying to decide what it is.

Christopher Smith: Macs are beautiful, PCs are vile | Celebrity squares
Film director Christopher Smith devours new gadgets but he won't download films as he's a sucker for DVDs What's your favourite piece of technology, and how has it improved your life? The thing that changed my life, and improved my life, was originally my video [player]. That idea of being able to rent movies genuinely changed me, I think. All of my filmgoing when I was a kid was watching videos. The most modern thing: I love my Sky+. I love the idea that I can use my iPhone and record stuff and having it waiting for me in a big bank. And I don't record movies – I record rubbish. When was the last time you used the Sky+ box, and what for? I used it the other day to record My Big Fat Gypsy Wedding for my wife. What additional features would you add if you could? I wouldn't change a thing, I just love it. I think it's perfect as it is. Do you think it will be obsolete in 10 years' time

Microsoft Office 2010 programs available separately
Microsoft has announced estimated retail pricing for Microsoft Office 2010 in the UK, but Cyteck only wants one application…. In response to your story about Microsoft Office 2010 priced from free , will it be possible in future to purchase Office 2010 applications as separate programs? I'm interested in Outlook, and I wonder if Ask Jack might be able to enlighten me on that. Cyteck Microsoft UK has just released estimated retail prices for separate applications, so you can assume that all of these will be available separately. Basically they all cost £119.99 each -- that's Word, Excel, PowerPoint, Outlook, Publisher and Access -- except for OneNote, which costs £69.99.

Vancouver Winter Olympics go green with recycled metals for medals
Circuit boards from trashed computers in Belgium recycled to provide tiny amounts of metal to make winter olympic medals The gold, silver and bronze medallions slung around winning athletes' necks as they step on to the winners' podium at the Vancouver Winter Olympic Games could well be made from the guts of an old Belgian computer. The manufacturer of medals for this Olympics is for the first time incorporating token amounts of recycled material into the medals. Medals historically have been made of freshly mines ores. The innovation – though largely symbolic – was directed by an Olympic organising committee which had vowed to put on the greenest games ever, raising the bar for London in 2012. Organisers aimed to cut greenhouse gas emissions by 15% from business as usual. The nine new buildings constructed for the games set a new green standard for any complex of buildings in North America, drawing heat from the ocean and exhaust systems, incorporating green roofs and solar panels. The village for the athletes will be converted into housing when the games are over. However, efforts to put on a green games were undermined by unseasonably warm conditions, which forced organisers to fly and truck in snow for the freestyle skiiing and snowboarding venue .

HP boosts computer industry with rising profit
The technology industry breathed a sigh of relief on Wednesday, after the world's largest computer manufacturer, Hewlett Packard, announced a 20% jump in quarterly profit. The Californian company said that revenues and income had risen significantly from this time last year, in what many saw as the strongest sign yet that the economic slump's impact on technology spending was almost over. Revenues for the first quarter of 2010 were up 8% to $31.2bn (£19.9bn), with profits rising to $2.3bn - up from $1.9bn a year ago. The company also said it was expecting more signs of recovery in the coming year, with projected earnings narrowly ahead of expectations. "HP is well-positioned to outperform the market," said chairman and chief executive Mark Hurd, who has worked to cut costs at the company since taking over in 2005. The growth largely came from HP's computer and printer manufacturing businesses, as consumers - who had been reticent about purchasing during the downturn - started buying again. While figures released by industry analysts Gartner suggested that shipments in western Europe were flat, the company experienced what Hurd called "accelerating market momentum". That could be partially due to the impact of Microsoft's Windows 7, which launched last autumn and gave many PC manufacturers a boost by encouraging shoppers to purchase new hardware. The company's services business - which expanded significantly in 2008 with the $12.6bn purchase of EDS - did not enjoy a revival, however, with revenue falling by 1%. HP's results will please investors and analysts, but they have not been without its costs. The company has cut tens of thousands of jobs in the past two years, including 25,000 as a direct result of the EDS acquisition, and plans a further 8,600 by October. Last month more than 1,000 HP staff who work for the Department of Work and Pensions took strike action in protest at job losses. Shares rose marginally in after hours trading, to 50.12.
