    Google Maps returns to the iPhone

    By Hayley Tsukayama, Published: December 13, 2012
    Google announced late Wednesday that its Maps app is back for the iPhone.

    Google Maps had been the default navigation service on the iPhone since the phone was first released in 2007. But earlier this year, Apple kicked the app off its mobile device and replaced it with its own mapping program, Maps. Many iPhone users balked at the notoriously inaccurate Apple navigation program and the loss of Google Maps, saying they would wait for Google to resubmit its app to the Apple store.
    The addition, however, doesn’t let Apple off the hook for improving its own Maps, which is playing catchup with Google as it tries to gather the amount and quality of navigation data it needs to bridge the gap between the two apps. Google Maps is known for being more comprehensive and generally more accurate than the other navigation apps out there.
    Google’s new iPhone mapping app adds features from Google’s Android that some Apple users have been longing for such as turn-by-turn directions for walking, mass transit and driving and a smooth integration of Google’s Street View technology. Navigation on the app is quick and intuitive.
    Google Maps also pulls transit information from several sites to make it easier to plan trips. In Washington, users can choose ..I.. I they want to go by bus, Metro or some combination of both and get clear route instructions with station names and clearly labeled bus stops.
    In this latest version, Google also makes it easier for users to flag the service if it gives the wrong directions. A shake of the iPhone triggers a dialogue box that offers the option to report errors or bugs directly to Google. There is at least one feature from Google Maps for Android that’s missing from the iPhone: the ability to save a portion of a map for offline use, which comes in handy when the phone’s battery runs low.

Internet insecurity

Once more unto the breach
Jun 3rd 2011, 11:02 by M.G. | SAN FRANCISCO

    DEFENCE companies have been left defenceless. The cyber attacks against Lockheed Martin and L-3 Communications, two American defence giants, as well as those against Google and America’s Public Broadcasting System (PBS) differ in their details. But they all highlight the fact that hackers are becoming ever more tenacious and creative in their attempts to get their hands on sensitive data.

    It’s not just American firms that are under attack. On June 2nd, a group of hackers calling itself “LulzSec” claimed that it had been able to get into the network of Sony Pictures. LulzSec (which also uses the moniker “The Lulz Boat”) claims it is behind the hacking of PBS’s website too.

    The rise of “hacktivism”, which involves groups of hackers not necessarily driven by financial gain (though this can be a handy by-product of their nefarious activities), poses a growing challenge to companies and governments. Often the motive is revenge. LulzSec claimed its attack on PBS was motivated by the media organisation’s decision to air an investigative report that included criticism of WikiLeaks, the organisation that has been publishing leaked diplomatic cables. Anonymous, a hacker collective that has gained global notoriety for penetrating the networks of credit-card companies and other organisations, has also justified some of its actions by saying they are protests at the way in which Julian Assange, the founder of WikiLeaks, has been persecuted by governments and courts.

Microsoft touts Windows 8's ability to detect, fix hard disk problems

The new operating system makes the process faster and less disruptive to the operation of the computer

    IDG News Service − Microsoft has revamped the way Windows 8 monitors hard disk operations and detects problems in an effort to make the diagnostic and repair process less intrusive and disruptive, even as disk capacity continues to balloon.
    The improvements in Windows 8 center on the ChkDsk utility, which inspects the hard disk and checks for a variety of errors and problems. Until now, running ChkDsk has often been inconvenient ..58.. end users have to stop using the machine while the utility runs, and the scan can take a long time to complete.
    Microsoft also tweaked NTFS, the Windows OS file system. Until now, the NTFS "health model" conceived the machine's hard disk as a single unit that was either well or damaged, and which thus was taken completely offline and made unavailable to the end user while ChkDsk ran, sometimes for hours.
    "Downtime was directly proportional to the number of files in the volume," reads Microsoft's blog post late Wednesday authored by Kiran Bangalore, senior program manager of Windows Core Storage and File Systems.
    In Windows 8, however, the NTFS scans for problems in the background while the system remains online, and an initial attempt to fix problems on-the-fly is done.
