Security researchers presenting at the Where 2.0 conference have revealed a hidden, secret iOS file that keeps a record of everywhere you've been. The record is synched to your PC and subsequently resynched to your other mobile devices. The file is not transmitted to Apple, but constitutes a substantial privacy breach if your PC or mobile device are lost or seized. The researchers, Alasdair Allan and Pete Warden, have released a free/open application called "iPhone Tracker" that allows you to retrieve the location data on your iOS device and examine it. They did not discover a comparable file on Android devices.

Det är förmodligen så man ska se på Spotify; det är ytterligare en livsuppehållande åtgärd för en industri som egentligen borde få somna in för gott. Det kommer heta att det är piratkopierarnas fel, man kommer skylla på ungefär allt som går att skylla på för att försöka skyla de egentliga orsakerna; en trasig och förlegad upphovsrätt och fullständigt föråldrade affärsmodeller inom upphovsrättsindustrin.

...

Spotifys affärsmodell är väldigt rätt, en Internetbaserad tjänst som ger dig ett musikbibliotek som är många gånger större än det du själv orkar sortera och indexera på egen hand, men det hjälper inte när de samtidigt tvingas hålla en obsolet och döende dinosaurie vid liv. Utan den dödvikten tror jag att Spotify hade varit markant mer framgångsrik, artisterna hade definitivt fått markant mer betalt och mycket av dagens kritik hade aldrig ens uppstått men med dagens beslut kommer kritikerna knappast bli tystare.

Japan has been asking foreign media to objectively report on the evolving crisis at the Fukushima Daiichi nuclear power plant, the Foreign Ministry said Thursday, as reports deemed sensationalist or based on incorrect information have fanned concern and led to import restrictions on Japanese products.

State Foreign Secretary Chiaki Takahashi told a press conference that Tokyo believes some reports by foreign media on the Fukushima crisis were ''excessive'' and has urged the organizations responsible for the stories through Japanese diplomatic missions abroad to correctly and objectively disseminate information.

Ministry officials said some foreign media, including tabloids, emphasized the danger of radioactive materials leaking from the Fukushima nuclear plant by focusing on extreme projections, while erroneously reporting that the plant operator Tokyo Electric Power Co. has hired homeless people to tackle the ongoing crisis.

One of the common problems I see in the media is the failure to distinguish between dose and dose rate. That's like mixing up miles and miles per hour. It makes a lot of what is reported confusing and hard to interpret.

Moreover, risk of harm is a function of both dose and dose rate. The same total dose spread relatively evenly over weeks, months, or years (chronic exposure) carries much lower risk of harm than the same total dose received over minutes, hours or days (acute exposure). This has to do with the body's ability to repair damage at the cellular level. So you can't really estimate risk accurately without knowing something about both dose and dose rate.

More than 10,000 people have died in the Japanese tsunami and the survivors are cold and hungry. But the media concentrate on nuclear radiation from which no-one has died - and is unlikely to.

Worst of all, the reporting has put the focus entirely on the Fukushima nuclear plant. As worrisome as the issue is, it has been completely blown out of proportion, with talk of meltdown and massive destruction. The tragedy is that the victims of the earthquake and tsunami are all but forgotten at times. While the world turns away to ponder its own nuclear policies — which, for better or for worse, are far from urgent — people are starving and dying after having survived the disaster itself.

The nuclear plant story is exciting and dramatic and is easy to exaggerate, but it will quickly wear thin as the plant cools and the international public realizes that the fears were deliberately whipped up. By then, it could be far too late for many survivors.

If you want to remove the outer casing on your iPhone 4 to replace the battery or a broken screen, it won't be easy anymore. In the past, you could use a Phillip screwdriver to remove two tiny screws at the base of the phone and then simply slide off the back cover.

But Apple is replacing the outer screw with a mysterious tamper-resistant screw across its most popular product lines, reports iFixit, a Web site that provides free repair manuals and advice forums mostly aimed at Apple products. Apple calls them "Pentalobular" screws.

New MacBook Pros, iPhone 4s and MacBook Airs will have the Pentalobular screw, making it harder for do-it-yourselfers to make repairs. What about existing products in the field? Pentalobular screws might find their way into them, too.

"They know how fast you read because you have to click to turn the page," says Cindy Cohn, legal director at the nonprofit Electronic Frontier Foundation. "It knows if you skip to the end to read how it turns out."

...

Cohn says this kind of page-view tracking may seem innocuous, but if the company keeps the data long-term, the information could be subpoenaed to check someone's alibi, or as evidence in a lawsuit.

And it's not just what pages you read; it may also monitor where you read them. Kindles, iPads and other e-readers have geo-location abilities; using GPS or data from Wi-Fi and cell phone towers, it wouldn't be difficult for the devices to track their own locations in the physical world.

DRM is used by Apple to restrict users' freedom in a variety of ways, including blocking installation of software that comes from anywhere except the official Application Store, and regulating every use of movies downloaded from iTunes. Apple furthermore claims that circumventing these restrictions is a criminal offense, even for purposes that are permitted by copyright law.

Apple (AAPL) is in talks with Microsoft (MSFT) to replace Google (GOOG) as the default search engine on its iPhone, according to two people familiar with the matter. The talks have been under way for weeks, say the people, who asked not to be named because the details have not been made public.
