49ers’ stadium Wi-Fi served 25,000 concurrent users, 2.13TB in all

Levi’s Stadium crowd on August 17, 2014. Jim Bahn The San Francisco 49ers’ heralded Wi-Fi network served its first NFL crowd in a preseason game on Sunday, and the team has now released statistics showing that it was able to serve lots of data to lots of fans, just as intended. “We offloaded 2.13 terabytes during the event,” 49ers VP of Technology Dan Williams told Mobile Sports Report . The newly built Levi’s Stadium has 68,500 seats and more than a third of attendees used the Wi-Fi network simultaneously. “We peaked at 24,775 (roughly 38 percent of attendance) concurrent connections with an average of 16,862 (roughly 25 percent of attendance),” Williams said.

Blizzard no longer expects World of Warcraft subscriber growth

The World of Warcraft isn’t usually this empty, but it’s getting there… For about six years after its early 2005 launch, it looked like there was nothing that could stop the runaway success of Blizzard’s World of Warcraft , which grew to a peak of 12 million paid subscribers by the end of 2010. Since then, though, the game has seen a long, mostly uninterrupted slide in its player numbers, with only 6.8 million subscribers as of July . Blizzard obviously isn’t happy about this trend for one of its biggest products but seems to have accepted that things aren’t going to change any time soon. “We really don’t know if [ World of Warcraft ] will grow again,” lead game designer Tom Chilton told MCV in a recent interview. “It is possible, but I wouldn’t say it’s something that we expect. Our goal is to make the most compelling content we can.” A new expansion pack like the upcoming Lords of Draenor could juice those subscriber numbers, as previous expansion packs have seemed to do. Chilton seems to see a bit of diminishing returns in this strategy, however. “By building expansions, you are effectively building up barriers to people coming back. But by including the level 90 character with this expansion, it gives people the opportunity to jump right into the new content.” Read 2 remaining paragraphs | Comments

YouTube subscription plan leaks: offline play, no ads, 20 million songs

A handful of the full set of screenshots obtained by Android Police. Android Police More details have leaked about Google’s upcoming subscription service for YouTube, these in the form of screenshots posted by Android Police on Monday. The service, called YouTube Music Key, will give subscribers ad-free and offline playback of YouTube videos, as well as audio-only material. Per the screenshots, users will be able to play music on their mobile phones “with or without video, in the background, or with your screen off”—all things that the single-tasking YouTube apps could not previously do. Subscribers will also be able to play music via “YouTube Mix,” a recently-added feature that works similarly to radio stations on other streaming services. A YouTube Music Key subscription provides access to a 20-million-song catalog, roughly the same size as that of Spotify and Rdio , as well as a collection of material the app refers to as “concerts, covers, and remixes.” While YouTube is rife with content beyond artists’ official discographies, a lot of it of legally questionable provenance, it’s not clear from the screenshots how Google will decide what goes into YouTube Music Key. Subscribers to the service will also be subscribed to “Google Play Music Key” for free, which is likely a rebranded Google Play Music All Access . Read 2 remaining paragraphs | Comments

Linux-on-the-desktop pioneer Munich now considering a switch back to Windows

The world is still waiting for the year of Linux on the desktop, but in 2003 it looked as if that goal was within reach. Back then, the city of Munich announced plans to switch from Microsoft technology to Linux on 14,000 PCs belonging to the city’s municipal government. While the scheme suffered delays , it was completed in December 2013. There’s only been one small problem: users aren’t happy with the software, and the government isn’t happy with the price. The switch was motivated by a desire to reduce licensing costs and end the city’s dependence on a single company. City of Munich PCs were running Windows NT 4, and the end of support for that operating system meant that it was going to incur significant licensing costs to upgrade. In response, the plan was to migrate to OpenOffice and Debian Linux. Later, the plan was updated to use LibreOffice and Ubuntu. German media are reporting that the city is now considering a switch back to Microsoft in response to these complaints. The city is putting together an independent expert group to look at the problem, and if that group recommends using Microsoft software, Deputy Mayor Josef Schmid of the CSU party says that a switch back isn’t impossible.

A brief history of USB, what it replaced, and what has failed to replace it

We’ve all had this first-world problem, but USB is still leagues better than what came before. Like all technology, USB has evolved over time. Despite being a “Universal” Serial Bus, in its 18-or-so years on the market it has spawned multiple versions with different connection speeds and many, many types of cables. The USB Implementers Forum , the group of companies that oversees the standard, is fully cognizant of this problem, which it wants to solve with a new type of cable dubbed Type-C . This plug is designed to replace USB Type-A and Type-B ports of all sizes on phones, tablets, computers, and other peripherals. Type-C will support the new, faster USB 3.1 spec with room to grow beyond that as bandwidth increases. It’s possible that in a few years, USB Type-C will have become the norm, totally replacing the tangled nest of different cables that we all have balled up in our desk drawers. For now, it’s just another excuse to pass around that dog-eared XKCD comic about the proliferation of standards . While we wait to see whether Type-C will save us from cable hell or just contribute to it, let’s take a quick look at where USB has been over the years, what competing standards it has fought against, and what technologies it will continue to grapple with in the future.

Photonic crystals used to make optical RAM

This photonic lattice created at Sandia National Laboratories acts like a crystal in guiding light because of its tiny, regularly placed silicon “logs.” Japanese researchers have shown how to use photonic crystals like this as optical RAM. Sandia National Labs Most high-speed networking is done using optical fibers. The hardware on each end of these fibers has to convert the optical signals to electronic ones in order to figure out a packet’s destination and will often return it to optical form before sending it on toward its destination. Researchers at the Japanese telecom NTT find all that converting a bit wasteful and are working on ways to avoid it. They’ve recently published a paper that includes a description of a working 115-bit optical Random Access Memory device, made of a carefully structured series of photonic crystals, each of which can store light of a different wavelength. Photonic crystals are made of layered semiconductors, with the precise structure (the thickness and spacing of the layers) determining how they interact with light—it’s possible to make photonic crystals that selectively block or transmit a narrow frequency range.

Wireless broadband can reach the moon, and maybe Mars

Prescott Pym Aside from air, water and fresh vegetables, what would need to survive on the moon? One thing that would likely of feature high on the list is a decent, reliable wireless internet. And thanks to a group of researches from MIT and Nasa this kind of connectivity could be within the realms of possibility. Between them, the two organizations have demonstrated for the first time that data communication technology is capable of providing those in space with the same kind of connectivity we enjoy on Earth, and can even facilitate large data transfers and high-definition video streaming. To do this it uses four separate telescopes based at a ground terminal in New Mexico to send the uplink signal to the moon. A laser transmitter that can send information as coded pulses of invisible infrared light feeds into each of the telescopes, which results in 40 watts of transmitter power.

Sailor convicted of hacking websites from aboard aircraft carrier

The USS Harry S. Truman apparently had adequate Internet bandwidth for a sailor to hack websites in his spare time. US Navy A 27-year old now-former sailor pleaded guilty in a federal court in Tulsa, Oklahoma on May 20 to charges of conspiracy after leading a band of hackers in the US and Canada from onboard an aircraft carrier . Nicholas Paul Knight, who was the system administrator for the USS Harry S. Truman’s nuclear reactors department, was caught trying to hack into a Navy database while at sea. Knight and a co-defendant—Daniel Kreuger of Salem, Illinois—were part of “Team Digi7al,” a collective of hackers who attacked at least 24 websites in 2012 in search of personal identifying information. Knight himself hacked the Navy’s Smart Web Move website , a system for sailors to manage household moves during transfers between stations; that hack included about 220,000 service members’ Social Security numbers, dates of birth, addresses, and other personal data. Other sites attacked by the group included ones operated by the Department of Homeland Security, the Library of Congress, Stanford University, Los Alamos National Laboratory, the Toronto Police Service, and the University of Nebraska-Lincoln.

Missing features we’d like to see in the next version of OS X

It’s only been about seven months since Apple released OS X 10.9, the latest and greatest version of its Mac operating system. But the yearly upgrade cycle means that unless something unexpected happens, Apple will tell us about OS X 10.10 at the traditional keynote next month on the first morning of its Worldwide Developers Conference (WWDC). The operating system is over 13 years old and it’s come a long way since those first versions , but it’s still not perfect. What areas do we think Apple should focus on in 10.10? Think of the SSDs Isn’t it time our modern hard drives got a modern filesystem? The latest Macs may have solid state drives that can read and write over 700 megabytes per second over a direct PCI Express connection, but all that data is still organized by a file system from the previous millennium: HFS+. There’s something to be said for using stable, battle-hardened code for the file system, which is probably the most critical part of the operating system. Unfortunately, Apple’s current HFS+ implementation isn’t as stable as it should be, much to the chagrin of Ars’ OS X reviewer extraordinaire John Siracusa. With the introduction of a logical volume manager—Core Storage—it looks like Apple has found a way to innovate in the area of storage without having to replace HFS+. One of the big missing features in HFS+ is snapshots . Time Machine, for example, works per-file. Changing a few bytes in the middle of a large file means that the entire file is copied during the next backup. With snapshots, that’s not necessary: multiple snapshots share the unmodified disk blocks. As such, snapshots could be implemented in Core Storage rather than in the file system. This would allow Time Machine backups to be much faster and more efficient. Read 18 remaining paragraphs | Comments

For Do Not Call violations, Sprint will pay FCC $7.5M in largest ever settlement

Hunter Edwards On Monday, Sprint agreed to pay the Federal Communications Commission $7.5 million to resolve violations of the Do Not Call registry—the largest settlement payout ever. The program first began in 2003 as a way to allow Americans to opt out of unsolicited sales calls. According to the FCC, Sprint will also put into effect a “robust compliance plan,” designate a new senior manager to deal with compliance, retrain its employees, and report any further noncompliance to the agency, among other necessary actions. “We expect companies to respect the privacy of consumers who have opted out of marketing calls,” said Travis LeBlanc, acting chief of the Enforcement Bureau, in a statement . “When a consumer tells a company to stop calling or texting with promotional pitches, that request must be honored. Today’s settlement leaves no question that protecting consumer privacy is a top enforcement priority.” Read 3 remaining paragraphs | Comments
