Submission + - Why doesn't Android support Linux filesystems for removable storage? 1

Pale Dot writes: After weeks of struggle I finally figured out a way for the apps on my rooted Android tablet to recognize an SD card I had formatted as Ext4 but with the default journaling option turned off. The problem at first was getting the SD card to mount at all (technically this was the "external" SD card as the tablet also has a built-in "internal" SD card). Apparently, the Android automount facility, the evil-sounding vold daemon, does not support any filesystem besides Microsoft's VFAT. From various online sources, I learned that the CyanogenMod Linux 3.x kernel itself does support mounting Ext4, at least via the terminal "mount -t ext4" command.

A second problem soon cropped up. Apps, such as VLC and the AardDict offline dictionary, that rely on some sort of automagic scanning of the device storage space would not index the media and database files I copied to the SD card. It turns out that the simple solution, or the "hack" as it stands, is to mount the SD card under the directory created for the internal VFAT-formatted SD card, i.e. as "/storage/sdcard0/extsd" rather than the more direct "/storage/sdcard1". This works probably because subdirectories inherit the file permissions of the parent.

As part of my Google (re)search into the problem, I came upon this Google+ post by an Android developer curiously named Dianne Hackborn about the design decision not to support anything besides the Redmond-certified filesystem: "The external storage when on a SD card is FAT. Period. You are just going to cause yourself a mess if you try to do otherwise. The basic semantics of how external storage is used relies on it being fat — no permissions, case insensitive, etc."

So, is Google right about not supporting Ext2/3/4 for removable flash media, even if the base system itself often uses one of these Linux-native filesystems? Supposed issues about the frequent media access needed by a journalised filesystem don't apply to Ext2, which has no journal, or Ext4, which has an "-O ^has_journal" (no journal) formatting option. Perplexing still is that my tablet is advertised as having support for yet another Microsoft-patented invention, the ExFat filesystem. Unfortunately, there's still no way for a non-rooted Android tablet or smartphone to mount an SD card formatted as Ext2 or Ext4.

Submission + - The Patents That Threaten 3-D Printing (

An anonymous reader writes: We've watched patents slow down the smartphone and tablet markets. We've seen patent claims thrown against Linux, Android, and countless other software projects. Now, as 3-D printing becomes more capable and more affordable, it seems a number of patents threaten to do the same to the hobbyist and tinkerer crowd. Wired has highlighted some of the most dangerous ones, including: a patent on soluble print materials that support a structure while it's being printed; a ridiculously broad patent on distributed rapid prototyping, which could affect "every 3-D printing service that has launched in the past few years"; and an 18-year-old patent on 3-D printing using a powder and a binding material, held by MIT.

Submission + - You Can Navigate Between Any Two Websites In 19 Clicks or Fewer (

An anonymous reader writes: A study done by a Hungarian physicist found that of the billions of websites and over a trillion objects on the web, any given two are separated by no more than 19 clicks. 'Distributed across the entire web, though, are a minority of pages—search engines, indexes and aggregators—that are very highly connected and can be used to move from area of the web to another. These nodes serve as the "Kevin Bacons" of the web, allowing users to navigate from most areas to most others in less than 19 clicks. Barabási credits this “small world” of the web to human nature—the fact that we tend to group into communities, whether in real life or the virtual world. The pages of the web aren’t linked randomly, he says: They’re organized in an interconnected hierarchy of organizational themes, including region, country and subject area. Interestingly, this means that no matter how large the web grows, the same interconnectedness will rule.'

Submission + - Drones still face major communications challenges getting onto US airspace (

coondoggie writes: "Communications and effective system control are still big challenges unmanned aircraft developers are facing if they want unfettered access to US airspace. Those were just a couple of the conclusions described in a recent Government Accountability Office report on the status of unmanned aircraft and the national airspace. The bottom line for now seems to be that while research and development efforts are under way to mitigate obstacles to safe and routine integration of unmanned aircraft into the national airspace, these efforts cannot be completed and validated without safety, reliability, and performance standards, which have not yet been developed because of data limitations"

Submission + - Supreme Court Approves Search Warrants Issued by Dogs (

Entropy98 writes: "Today the U.S. Supreme Court unanimously ruled that "a court can presume" an alert by a drug-sniffing dog provides probable cause for a search.

The Supreme Court has not yet issued a ruling in Florida v. Jardines, the other drug dog case it heard last October. Jardines raises the question of whether police need a warrant to use a drug-sniffing dog at the doorstep of a home.

The police can now search anyone anywhere as long as their dog "alerts". Soon coming to your front door as well."


Submission + - BlackBerry Vulnerability Could Allow Access to Enterprise Server (

Trailrunner7 writes: A vulnerability exists in some components of BlackBerry mobile devices that could grant attackers access to instances of the company’s Enterprise Server (BES), according to Research in Motion (RIM), which issued an alert and released a patch for the vulnerability last week via its Knowledge Base support site. BES, the software implicated by the vulnerability, helps companies deploy BlackBerry devices.

The high severity advisory involves the way the phone views Tagged Image File Format (TIFF) files, specifically the way the phone’s Mobile Data System Connection Service and Messaging Agent processes and renders the images.

An attacker could rig a TIFF image with malware and get a user to either view the image via a specially crafted website or send it to the user via email or instant message. The last two exploit vectors could make it so the user wouldn’t have to click the link or image, or view the email or instant message, for the attack to prove successful. Once executed, an attacker could access and execute code on Blackberry’s Enterprise Server

Submission + - Sensors pick up North Korean radioactivity (

gbrumfiel writes: "A global network of sensors has picked up faint traces of radioactive gas that probably seeped from last week's underground nuclear test by North Korea. The detection of xenon-133 in Japan and Russia provide further evidence of the nuclear nature of the test, but offer no hint as to the type of weapon used. Atmospheric modelling by the Central Institute for Meteorology and Geodynamics in Vienna shows that the gas likely seeped from North Korea's test site on 15 February, three days after the original test. That indicates that the test was well sealed deep underground."

Submission + - Does the Higgs Boson Reveal Our Universe's Doomsday? (

astroengine writes: "If calculations of the newly discovered Higgs boson particle are correct, one day, tens of billions of years from now, the universe will disappear at the speed of light, replaced by a strange, alternative dimension, one theoretical physicist calls boring. "It may be that the universe we live in is inherently unstable and at some point billions of years from now it’s all going to get wiped out. This has to do with the Higgs energy field itself,” Joseph Lykken, with the Fermi National Accelerator Laboratory in Batavia, Ill., told Discovery News. "This calculation tells you that many tens of billions of years from now there’ll be a catastrophe.""

Submission + - Oxford temporarily blocks Google Docs to fight phishing (

netbuzz writes: "Fed up with phishers using Google Forms to commandeer campus email accounts as spam engines, Oxford University recently blocked access to Google Docs for two-and-a-half hours in what it called an “extreme action” designed to get the attention of both its users and Google. “Seeing multiple such incidents the other afternoon tipped things over the edge,” Oxford explains in a blog post. “We considered these to be exceptional circumstances and felt that the impact on legitimate University business by temporarily suspending access to Google Docs was outweighed by the risks to University business by not taking such action.” The move generated widespread complaints from those affected, as well as criticism from outside network professionals."

Submission + - Monsanto's 'terminator' seeds set to make a comeback (

ananyo writes: "Monsanto and other biotechnology firms could be looking to bring back 'terminator' seed technology. The seeds are genetically engineered so that crops grown from them produce sterile seed and prompted such an outcry that, as slashdot noted, Monsanto's chief executive pledged not to commercialize them. But a case in the US Supreme Court could allow farmers to plant the progeny of GM seeds rather than buying new seeds from Monsanto, making the technology attractive to biotech companies again. Some environmentalists also see 'terminator' seeds as a way of avoiding GM crops contaminating organic/non-GM crops."
