New submitter PopHollywood writes "Is iOS 7 slower than version 6? After upgrading, myself and a few others notice slow, choppy experience when scrolling, changing apps, etc. Is this common?" For those using iOS in general, what's been your experience with the new upgrade?
Dputiger writes "Given the recent emphasis on mobile computing and the difficulty of scaling large cores, it's easy to think that enthusiast computing is dead. Easy — but not necessarily true. There are multiple ways to attack the problem of continued scaling, including new semiconductor materials, specialized co-processor units that implement software applications in silicon, and enhanced cooling techniques to reduce on-die hot spots."
beltsbear writes "Your formerly working clone Lightning cable could stop working with the latest iOS update. Previously the beta version allowed these cables to charge with a warning message but the final release actually stops many cables from working. Apples Lightning connector system is locked with authentication chips that can verify if a cable is authorized by Apple. Many users with clone cables are now without the ability to charge their iPhones."
rroman writes "RSA has recommended developers not to use Dual_EC_DRBG random number generator (RNG), which has been known to be weak and slow since 2006. The funny thing is, that even though this has been known for so long, it is the default RNG in BSafe cryptographic toolkit, which is product of RSA."
An anonymous reader writes "The National Security Agency sent a letter to its employees, affiliates and contractors to reassure them that the NSA is not really an abusive and unchecked spying agency engaged in illegal activity." Whatever you think of the commentary, you can read the original, attached to the linked story.
schwit1 writes "In a paper published today on the Los Alamos astro-ph preprint service, astronomers propose that as many as eleven past extinction events can be linked to the Sun's passage through the spiral arms of the Milky Way. (You can download the paper here [pdf].) From the paper: 'A correlation was found between the times at which the Sun crosses the spiral arms and six known mass extinction events. Furthermore, we identify five additional historical mass extinction events that might be explained by the motion of the Sun around our Galaxy. These five additional significant drops in marine genera that we find include significant reductions in diversity at 415, 322, 300, 145 and 33 Myr ago. Our simulations indicate that the Sun has spent ~60% of its time passing through our Galaxy's various spiral arms.'"
Hugh Pickens DOT Com writes "Tom Simonite reports at MIT Technology News that a new research group within Facebook is working on an emerging and powerful approach to artificial intelligence known as deep learning, which uses simulated networks of brain cells to process data. Applying this method to data shared on Facebook could allow for novel features, and perhaps boost the company's ad targeting. Deep learning has shown already potential to enable software to do things such as work out the emotions or events described in text even if they aren't explicitly referenced, recognize objects in photos, and make sophisticated predictions about people's likely future behavior. Facebook's chief technology officer, Mike Schroepfer, says that one obvious place to use deep learning is to improve the news feed, the personalized list of recent updates he calls Facebook's 'killer app.' Facebook already uses conventional machine learning techniques to prune the 1,500 updates that average Facebook users could possibly see down to 30 to 60 that are judged to be most likely to be important to them. 'The data set is increasing in size, people are getting more friends, and with the advent of mobile, people are online more frequently,' says Schroepfer. 'It's not that I look at my news feed once at the end of the day; I constantly pull out my phone while I'm waiting for my friend, or I'm at the coffee shop. We have five minutes to really delight you.'"
MojoKid writes "3D Printing start-up Ultimaker announced its second generation printer, the Ultimaker 2. The new printer features significant redesigns from the first iteration of the Ultimaker. The company says that the new machine is more accurate, more efficient, and it's even quieter at 49dB. Specifically, the Ultimaker 2 has a new CNC-milled case (that's all white with glowing sidewalls) with an OLED display, and its glass and aluminum build platform is designed to cool quickly so you can peel completed projects off more easily. The Ultimaker 2 can print with multiple materials, including PLA, ABS, and PVA, and is WiFi-compatible so you can print from a mobile device or computer. Ultimaker is also launching its Cura open source software, which the company claims can pre-process 3D files some 60 times faster than other open source applications and makes it easy to load and work with 3D files."
gentryx writes "In scientific computing a huge pile of code is still written in Fortran. One reason for this is that codes often evolve over the course of decades and rewriting them from scratch is both risky and costly. While OpenMP and OpenACC are readily available for Fortran, only few tools support authors in porting their codes to MPI clusters, let alone supercomputers. A recent blog post details how LibGeoDecomp (Library for Geometric Decompostition codes), albeit written in C++, can be used to port such codes to state-of-the-art HPC systems. Source code modification is required, but mostly limited to restructuring into a new pattern of subroutines."
An anonymous reader writes "Attempts to build a new telecommunications cable between the US, New Zealand and Australia have become a nexus for the growing rivalry between the U.S. and China in the Pacific. The U.S. is reportedly creating a technology ring fence to match its military one and contain China's ambitions in the Pacific. The U.S. military could even help pay for any planned new cable to link its bases in American Samoa with its expanding military presence in Australia's Northern Territory. It has been made 'very clear' U.S. authorities would not allow significant Chinese investment in one cable project and it followed that they would not tolerate the use of Chinese gear in its construction. 'It was made very clear. These are cables connecting whole countries. These are very political things,' one insider said."
toygeek writes "If you've been in IT long enough, you're bound to have heard the phrase 'Never underestimate the bandwidth of a station wagon filled with backup tapes.' These days moving data has become so much easier; We've surpassed baud rates and are into Gbps fiber on the backbones, and even in some homes. So, what's the modern equivalent to this, and what does it take to make the OC fiber connections cringe? Follow along as we theoretically stuff MicroSD cards into a Chevy Suburban and see what happens, and take sneakernet to a whole new level."
MTorrice writes "By attaching a lightweight, inexpensive device to the back of a smart phone, scientists can convert the phone into a sensitive fluorescence microscope. The attachment [paper abstract] allows the phone's camera to take pictures of single nanoparticles and viruses, possibly providing a portable diagnostic tool for health care workers in developing countries. For example, doctors in remote regions could use the technique to measure HIV viral loads in patients' blood samples, allowing the doctors to easily monitor disease progression and determine the best course of treatment."
An anonymous reader writes "Songbirds living along the Hudson River in New York state are exposed to levels of PCBs that don't kill them but do disrupt the songs they sing, reports a team of researchers from Cornell University. Their study reveals that birds residing in regions with higher environmental PCB contamination levels have higher total blood PCBs, which affects their singing behaviour: the team found these species' songs varied predictably based on their PCB load, and also based upon the type of PCBs. Thus, the scientists suggest that another of the many toxic effects of sublethal environmental PCB pollution are neurological effects that translate into observable behaviour changes that disrupt song quality used by birds to communicate."
cold fjord writes with this Business Week report: "LinkedIn Corp. ... was sued by customers who claim the company appropriated their identities for marketing purposes by hacking into their external e-mail accounts and downloading contacts' addresses. The customers, who aim to lead a group suit against LinkedIn, asked a federal judge in San Jose, California, to bar the company from repeating the alleged violations and to force it to return any revenue stemming from its use of their identities to promote the site ... 'LinkedIn's own website contains hundreds of complaints regarding this practice,' they said in the complaint filed Sept. 17. ... LinkedIn required the members to provide an external e-mail address as their username on its site, then used the information to access their external e-mail accounts when they were left open ... 'LinkedIn pretends to be that user and downloads the e-mail addresses contained anywhere in that account to LinkedIn's servers,' they said. 'LinkedIn is able to download these addresses without requesting the password for the external e-mail accounts or obtaining users' consent.'" "This puts an interesting twist on LinkedIn's recent call for transparency," adds cold fjord. (More at Bloomberg.)
