NASA Scientists Paint Stark Picture of Accelerating Sea Level Rise 226

A NASA panel yesterday announced widely reported finding that global sea levels have risen about three inches since 1992, and that these levels are expected to keep rising as much as several more feet over the next century -- on the upper end of model-based predictions that have been made so far. From the Sydney Morning Herald piece linked above: NASA says Greenland has lost an average of 303 gigatons [of ice] yearly for the past decade. Since it takes 360 gigatons to raise sea level by a millimetre, that would suggest Greenland has done this about eight times over just in the last 10 years or so. "People need to be prepared for sea level rise," said Joshua Willis, an oceanographer at NASA's Jet Propulsion Laboratory in La Cañada Flintridge. "It's not going to stop."

Since-Pulled Cyanogen Update For Oneplus Changes Default Home Page To Bing 80

ourlovecanlastforeve writes: Nestled into GSMArena's report on the Cyanogen OS 12.1 update for Oneplus [ Note: an update that the story reports has since been pulled.] is this tasty bite: "...you'll find out that your Chrome homepage has been changed to Bing." Then it's casually dismissed with "Thankfully though, you can easily get rid of Microsoft's search engine by using Chrome settings." as if this were the most normal thing to have to do after an OTA update. Is this the new normal? Has Microsoft set a new precedent that it's okay to expect users to have to go searching through every setting and proactively monitor network traffic to make sure their data isn't being stolen, modified or otherwise manipulated?

Ask Slashdot: Tips For Getting Into Model Railroading? 148

An anonymous reader writes: A relative of mine has been hinting that he'd like me to take over his model railroad collection in the event of his death (or even before that, to make this a bit less morbid-sounding). I'm intrigued by the idea, because I've been interested in model railroads for years, but too commitment shy and too transient to actually start a collection. That's changed enough that I'd like to start planning a train system, and am looking for advice from people who have been at it for a while. A couple of parameters: 1) I'm only interested for now in HO-scale stuff, so I am not all that interested in the relative merits of the other kinds, cool as they might be. 2) Related, I am somewhat less interested in the rolling stock than I am in the construction and control of the track and surrounding landscape. Interested in learning from experienced model railroad enthusiasts what lessons you've learned over the years that would be useful for a newbie, especially if you've made some cool automation for your system, or have built extensive support structures. This includes negative lessons, too, if you've overloaded circuits or floorboards. I'd *like* to integrate some interesting sensors and control systems, and I see some interesting open source software for this. So: What advice would you give to a late-start railroader? For reference: this set-up may end up living in an unfinished suburban basement.

The Top 10 Programming Languages On GitHub, Over Time 132

An anonymous reader writes with a link to VentureBeat's article on the information that GitHub released this week about the top-ten languages used by GitHub's users, and how they've changed over the site's history. GitHub's chart shows the change in rank for programming languages since GitHub launched in 2008 all the way to what the site's 10 million users are using for coding today. To be clear, this graph doesn't show the definitive top 10 programming languages. Because GitHub has become so popular (even causing Google Code to shut down), however, it still paints a fairly accurate picture of programming trends over recent years. Trend lines aside, here are the top 10 programming languages on GitHub today: 1. JavaScript 2. Java 3. Ruby 4. PHP 5. Python 6. CSS 7. C++ 8. C# 9. C 10. HTML

Meet Linux's Newest File-System: Bcachefs 131

An anonymous reader writes: Bcachefs is a new open-source file-system derived from the bcache Linux kernel block layer cache. Bcachefs was announced by Kent Overstreet, the lead Bcache author. Bcachefs hopes to provide performance like XFS/EXT4 while having features similar to Btrfs and ZFS. The bachefs on-disk format hasn't yet been finalized and the code isn't yet ready for the Linux kernel. That said, initial performance results are okay and "It probably won't eat your data — but no promises." Features so far for Bcachefs are support for multiple devices, built-in caching/tiering, CRC32C checksumming, and Zlib transparent compression. Support for snapshots is to be worked on.

Linux Foundation Project Will Evaluate Security of Open Source Software 37

An anonymous reader writes: The Core Infrastructure Initiative (CII), a project managed by The Linux Foundation, is developing a new free Badge Program, seeking input from the open source community on the criteria to be used to determine security, quality and stability of open source software. The first draft of the criteria is available on GitHub and is spearheaded by David A. Wheeler, an open source and security research expert who works for the Institute for Defense Analyses and is also coordinating the CII's Census Project, and Dan Kohn, a senior adviser on the CII.

AMD Still Struggling With Linux Gaming 100

An anonymous reader writes: AMD's Linux gaming performance has been embarrassingly bad, and it doesn't look like there's any quick remedy. Virtual Programming just released Dirt: Showdown for Linux, and it's the latest example of AMD's Linux driver issues: AMD's GPU results are still far behind NVIDIA's, with even the Radeon R9 Fury running slower than NVIDIA's aging GTX 680 and GTX 760. If a racing game doesn't interest you, Feral Interactive confirmed they are releasing Company of Heroes 2 for Linux next week, but only NVIDIA and Intel graphics are supported.

BitTorrent Clients Can Be Made To Participate In High-Volume DoS Attacks 47

An anonymous reader writes: A group of researchers have discovered some of the most popular BitTorrent applications, including uTorrent, Mainline, and Vuze are vulnerable to a newly discovered form of distributed denial of service attack that makes it easy for a single person to bring down large sites. The weaknesses allow an attacker to insert the target's IP address instead of their own in the malicious request. To mount a Distributed Reflective DoS (DRDoS) attack, an attacker sends this malformed requests to other BitTorrent users, which then act as reflectors and amplifiers and flood the intended victim with responses.

Registered Clinical Trials Make Positive Findings Vanish 118

schwit1 writes: The requirement that medical researchers register in detail the methods they intend to use in their clinical trials, both to record their data as well as document their outcomes, caused a significant drop in trials producing positive results. From Nature: "The study found that in a sample of 55 large trials testing heart-disease treatments, 57% of those published before 2000 reported positive effects from the treatments. But that figure plunged to just 8% in studies that were conducted after 2000. Study author Veronica Irvin, a health scientist at Oregon State University in Corvallis, says this suggests that registering clinical studies is leading to more rigorous research. Writing on his NeuroLogica Blog, neurologist Steven Novella of Yale University in New Haven, Connecticut, called the study "encouraging" but also "a bit frightening" because it casts doubt on previous positive results."

In other words, before they were required to document their methods, research into new drugs or treatments would prove the success of those drugs or treatment more than half the time. Once they had to document their research methods, however, the drugs or treatments being tested almost never worked. The article also reveals a failure of the medical research community to confirm their earlier positive results. It appears the medical research field has forgotten this basic tenet of science: A result has to be proven by a second independent study before you can take it seriously. Instead, they would do one study, get the results they wanted, and then declare success.

How Weather Modeling Gets Better 43

Dr_Ish writes: Bob Henson over at Weather Underground has posted a fascinating discussion of the recent improvements made to the major weather models that are used to forecast hurricanes and the like. The post also included interesting links that explain more about the models. Quoting: "The latest version of the ECMWF model, introduced in May, has significant changes to model physics and the ways in which observations are brought into and used within the model. The overall improvements include better portrayal of clouds and precipitation, including a more accurate depiction of intense rainfall. The main effect of the model upgrade for tropical cyclones is slightly lower central pressure. During the first 3 days of a forecast, the ECMWF has tended to have a slight weak bias on tropical cyclones; the new version is closer to the mark."

Octopus Genome Sequenced 43

An anonymous reader writes: A large, international team of researchers has completed the full sequencing of the octopus genome. "The researchers discovered striking differences between the genomes of the octopus and other invertebrates, including widespread rearrangements of genes and a dramatic expansion of a family of genes involved in neuronal development that was once thought to be unique to vertebrates." Among other things, the data allows scientists to more deeply analyze the creature's unique nervous system. "The central brain surrounds the esophagus, which is typical of invertebrates, but it also has groups of neurons in the arms that can work relatively autonomously, plus huge optic lobes involved in vision." Their study has been published in Nature.

Redefining Security Visualization With Hollywood UI Design 55

An anonymous reader writes: Most security interfaces today leave a lot to be desired, and many security pros are gaming enthusiasts, accustomed to a sharp and engaging virtual world. ProtectWise CEO Scott Chasin and CTO Gene Stevens wanted to give them a helpful security tool with an interactive visual dashboard that looks straight out of Call of Duty. The UI is called ProtectWise Visualizer, and its creator is Jake Sargeant, FX pro and a visual designer at MN8 Studio. If his name sounds familiar, it's because he was the Lead Animated Graphics Artist for the movie TRON: Legacy. There's plenty of inspiration available for movie-style UIs; the problem with much of it is that not everyone likes an interface that looks like an especially busy video game.

Facebook Awards Researchers $100k For Detecting Emerging Class of C++ Bugs 73

An anonymous reader writes: Facebook has awarded $100,000 to a team of researchers from Georgia Tech University for their discovery of a new method for identifying "bad-casting" vulnerabilities that affect programs written in C++. "Type casting, which converts one type of an object to another, plays an essential role in enabling polymorphism in C++ because it allows a program to utilize certain general or specific implementations in the class hierarchies. However, if not correctly used, it may return unsafe and incorrectly casted values, leading to so-called bad-casting or type-confusion vulnerabilities," the researchers explained in their paper.

Will Ad Blockers Kill the Digital Media Industry? 519

HughPickens.com writes: Michael Rosenwald writes at the Columbia Journalism Review that global online ad revenue continues to rise, reaching nearly $180 billion last year. But analysts say the rise of ad blocking threatens the entire industry—the free sites that rely exclusively on ads, as well as the paywalled outlets that rely on ads to compensate for the vast majority of internet users who refuse to pay for news. A new report from Adobe and one of several startups helping publishers fight ad blocking shows that 198 million people globally are now blocking ads, up 41 percent from 2014. In the US, ad blocking grew 48 percent from last year, to 45 million users. "Taken together, ad blockers are hitting publishers in their digital guts," writes Rosenwald. "Adobe says that $21.8 billion in global ad revenue will be blocked this year."

Publishers have been banking on the growth of mobile, where the ad blocking plugins either don't work or are cumbersome to install. A Wells Fargo analyst wrote in a report on ad blocking that "the mobile migration should thwart some of the growth" of ad blockers. But Apple recently revealed that its new operating system scheduled for release this fall will allow ad blocking on Safari. Apple is trying to pull iPhone and iPad users off the web. It wants you to read, watch, search, and listen in its Apple-certified walled gardens known as apps. It makes apps, it approves apps, and it profits from apps. But, for its plan to work, the company will need those entertainers and publishers to funnel their content to where Apple wants it to be. As the company makes strategic moves to devalue the web in favor of apps, those content creators dependent on ads to stay afloat may be forced to play along with Apple. Adblock Plus has released a browser for mobile Android devices that blocks ads, and it's planning to release a similar product for Apple devices. "The desire to figure out how to bring ad blocking to mobile consumers is a worldwide phenomenon," says Roi Carthy Ad blocking, he says, "is an inalienable right."

Lenovo Installed Software On Laptops That Persisted After Complete Wipes 163

An anonymous reader writes: The Next Web has confirmed reports from owners of Lenovo laptops that the company used a BIOS feature to install its software on the laptops even if a user wiped a device clean and reinstalled the operating system. "If Windows 7 or 8 is installed, the BIOS of the laptop checks 'C:\Windows\system32\autochk.exe' to see if it's a Microsoft file or a Lenovo-signed one, then overwrites the file with its own. Then, when the modified autochk file is executed on boot, another two files LenovoUpdate.exe and LenovoCheck.exe are created, which set up a service and download files when connected to the internet." Lenovo has published a patch to remove this functionality. The article notes that this technique seems to be sanctioned by a Microsoft policy. "Manufacturers are obligated to ensure that the mechanism can be updated if an attack is discovered and should be removable by the user, but the rules outlined in the document are fairly loose and don't require the OEM to notify the owner of the laptop that such a mechanism is in place."

Severe Deserialization Vulnerabilities Found In Android, 3rd Party Android SDKs 105

An anonymous reader writes: Closely behind the discoveries of the Stagefright flaw, the hole in Android's mediaserver service that can put devices into a coma, and the Certifi-gate bug, comes that of an Android serialization vulnerability that affects Android versions 4.3 to 5.1 (i.e. over 55 percent of all Android phones). The bug (CVE-2015-3825), discovered by IBM's X-Force Application Security Research Team in the OpenSSLX509Certificate class in the Android platform, can be used to turn malicious apps with no privileges into "super" apps that will allow cyber attackers to thoroughly "own" the victim's device. In-depth technical details about the vulnerabilities are available in this paper the researchers are set to present at USENIX WOOT '15.

Ask Slashdot: Switching To a GNU/Linux Distribution For a Webdesign School 233

spadadot writes: I manage a rapidly growing webdesign school in France with 90 computers for our students, dispatched across several locations. By the end on the year it will amount to 200. Currently, they all run Windows 8 but we would love to switch to a GNU/Linux distribution (free software, easier to deploy/maintain and less licensing costs). The only thing preventing us is Adobe Photoshop which is only needed for a small amount of work. The curriculum is highly focused on coding skills (HTML, CSS, JavaScript, PHP/MySQL) but we still need to teach our students how to extract images from a PSD template. The industry format for graphic designs is PSD so The Gimp (XCF) is not really an option. Running a Windows VM on every workstation would be hard to setup (we redeploy all our PCs every 3 months) and just as costly as the current setup. Every classroom has at least 20Mbit/s — 1Mbit/s ADSL connection so maybe setting up a centralized virtualization server would work? How many Windows/Photoshop licenses would we need then? Anything else Slashdot would recommend?

OpenGL ES 3.2 & New Extensions Unveiled 46

An anonymous reader writes: With kicking off ACM SIGGRAPH '15, The Khronos Group came out with several big announcements, including the release of OpenGL ES 3.2 (which incorporates Android AEP functionality), confirmation that Google will support Vulkan on Android (when released), new desktop OpenGL extensions, and updates to the existing OpenCL 2.0 specification. They stopped short of releasing the heavily anticipated Vulkan Graphics API and also refrained from releasing a new desktop OpenGL version. They hope to have the Vulkan specification and its implementations released before year's end.
