  • 4G Phones Are Really Fast — At Draining Batteries


    Hugh Pickens writes "With Verizon's 4G network covering a good chunk of the country and AT&T gaining ground, more smartphone users have access to the fastest wireless service available. But because 4G coverage isn't truly continuous in many locations, users' batteries are taking a big hit with 4G, as phones spend an lot of battery power trying to hunt down a signal. 'You've got a situation where the phones are sending out their signals searching and searching for a 4G tower, and that eats up your battery,' says Carl Howe, a vice president for research firm Yankee Group. The spottiness of 4G stems at least in part from the measured approach carriers have taken to it, rolling out the service city by city. There are a few tricks 4G users can try to extend battery life such as turning off your 4G connection when you don't need the fastest speeds — when using email, for instance — or using a program such as JuiceDefender to search for apps you may have downloaded that you don't need to run all the time, and erase them."

  • Ask Slashdot: Making JavaScript Tolerable For a Dyed-in-the-Wool C/C++/Java Guy?


    DocDyson writes "I'm a dyed-in-the-wool C/C++/Java developer with over 20 years of experience. I'm making a good living and having fun doing back-end Java work right now, but I strongly believe in being a generalist, so I'm finally trying to learn the HTML5/CSS3/JavaScript future of the Web. However, I find JavaScript's weak typing and dynamic nature difficult to adapt to because I'm so used to strongly-typed, compiled languages with lots of compile-time error-checking and help from the IDE. Does anyone out there who has made this transition have any tips in terms of the best tools and libraries to use to make JavaScript more palatable to us old-school developers?"

  • Should Next-Gen Game Consoles Be Upgradeable?


    MojoKid writes "Historically, console add-ons that boosted the performance of the primary unit haven't done well. Any attempt to upgrade a system's core performance risks bifurcating the user base and increases work developers must do to ensure that a game runs smoothly on both original and upgraded systems. The other reason is that a number of games rely on very specific hardware characteristics to ensure proper operation. In a PC, swapping a CPU with 256K of L2 for a chip with 512K of L2 is a non-issue assuming proper platform support. Existing software will automatically take advantage of the additional cache. The Xbox 360, on the other hand, allows programmers to lock specific cache blocks and use them for storing data from particular threads. In that case, expanding the amount of L2 cache risks breaking previous games because it changes the range of available cache addresses. The other side of the upgrade argument is that the Xbox 360 has been upgraded more effectively than any previous console; current high-end versions ship with more than 10x the storage of the original, as well as support for HDMI and integrated WiFi. It would also forestall the decline in comparative image quality between console and PC platforms."

  • History Repeats Itself: KDP Select Is Amazon.com's 'Payback For Playback'


    New submitter brennanw writes "Anyone who was active on mp3.com during the late 90s/early 2000's will find Amazon.com's KDP Select awfully familiar: authors who make their works exclusive to Amazon compete for a pool of money. Any time someone 'borrows' one of their books, they get a cut of a monthly sum (700K in January, 600K for February) based on how many of their books were checked out vs. how many other author's books were checked out. This is almost identical to the 'Payback for Playback' service MP3.com provided musicians a little over a decade ago. Payback for Playback effectively destroyed the original MP3.com artist community, and I don't think KDP Select is going to be much different for the self-publishing community that is growing on Amazon."

  • Higgs Signal Gains Strength


    ananyo writes "Today the two main experiments at the Large Hadron Collider, the world's most powerful particle accelerator, submitted the results of their latest analyses. The new papers (here here and here) boost the case for December's announcement of a possible Higgs signal. Physicists working on the In the case of the Compact Muon Solenoid experiment, have been able to look at another possible kind of Higgs decay, and that allows them to boost their Higgs signal from 2.5 sigma to 3.1 sigma. Taken together with data from the other detector, ATLAS, Higgs' overall signal now unofficially stands at about 4.3 sigma."
