Linux 4.9-rc8

3 hours 29 min ago

So if anybody has been following the git tree, it should come as no
surprise that I ended up doing an rc8 after all: things haven't been
bad, but it also hasn't been the complete quiet that would have made
me go "no point in doing another week".

Extra kudos to Arnd, who actually root-caused the incredibly annoying
"modversions do not work with new versions of binutils", bisecting it
to a particular change to symbol handling in binutils, and then adding
a small one-liner patch to the kernel to work around the issue. We
already had other workarounds in place, but it's always good to know
exactly what in the tool chain changed to cause things like this.

  • China builds world’s fastest supercomputer without U.S. chips

    China on Monday revealed its latest supercomputer, a monolithic system with 10.65 million compute cores built entirely with Chinese microprocessors. This follows a U.S. government decision last year to deny China access to Intel's fastest microprocessors.

    There is no U.S.-made system that comes close to the performance of China's new system, the Sunway TaihuLight. Its theoretical peak performance is 124.5 petaflops, according to the latest biannual release today of the world's Top500 supercomputers. It is the first system to exceed 100 petaflops. A petaflop equals one thousand trillion (one quadrillion) sustained floating-point operations per second.

    The most important thing about Sunway TaihuLight may be its microprocessors. In the past, China has relied heavily on U.S. microprocessors in building its supercomputing capacity. The world's next fastest system, China's Tianhe-2, which has a peak performance of 54.9 petaflops, uses Intel Xeon processors.

  • It's official: Kondik is gone from the Cyanogen that bore his handle [Ed: Microsoft deal killed them. As usual.]

    STEVE KONDIK, the original founder of Cyanogen, has been officially ousted from the company following the closure of its Seattle base.

    As reported yesterday, Kondik told developers that he "f*cked up and was f*cked over" and that he was considering what to do next given that he had lost control of rights to the Cyanogen name when he and his co-founder had moved from developer group to business.

    Kondik, aka CyanogenMod, relinquished all control over the operation of the business taking on the moniker of chief science officer, which may or may not have been a simple honorific.

  • Ransomware: Windows is the elephant in the room

    Ransomware has slowly become the most common and most difficult threat posed to companies and individuals alike over the last year.

    And there is one common thread to practically all ransomware attacks: Windows.

    Microsoft acolytes, supporters and astro-turfers can scream till they are blue in the face, but it is very rare to see ransomware that attacks any other platform.

    Of course, these Redmond backers are careful to say that ransomware attacks "computer users", not Windows users.

    But statistics tell the truth. In 2015, the average number of infections hitting Windows users was between 23,000 and 35,000, according to Symantec.

    In March, this number ballooned to 56,000 with the arrival of the Locky ransomware. And in the first quarter of 2016, US$209 million was paid by Windows users in order to make their locked files accessible again.

  • Hyper Is a Terminal Emulator Built Using Web Technologies

    A lot of us use the terminal on Ubuntu, typically from an app like GNOME Terminal, Xterm or an app like Guake.

    But did you know that there’s an JS/HTML/CSS Terminal? It’s called Hyper (formerly/also known as HyperTerm, though it has no relation to the Windows terminal of the same/similar name) and, usefulness aside, it’s certainl a novel proof-of-concept.

    “The goal of the project,” according to the official website, “is to create a beautiful and extensible experience for command-line interface users, built on open web standards.”

  • Core Apps Hackfest 2016: report

    I spent last weekend at the Core Apps Hackfest in Berlin. The agenda was to work on GNOME’s core applications: Documents, Files, Music, Photos, Videos, Usage, etc.; to raise their overall standard and to make them push beyond the limits of the framework. There were 19 of us and among us we covered a wide range of modules and areas of expertise.

    I spent most of my time on the plumbing necessary for Documents and Photos to use GtkFlowBox and GtkListBox. The innards of Photos had already been overhauled to reduce its dependency on GtkTreeModel. Going into the hackfest we were sorely lacking a widget that had all the bells and whistles we need — the idiomatic GNOME 3 selection mode, and seamlessly switching between a list and grid view. So, this is where I decided to focus my energy. As a result, we now have a work-in-progress GdMainBox widget in libgd to replace the old GtkIconView/GtkTreeView-based GdMainView.

  • Did Amazon Just Kill Open Source?

    Back in the days, we used to focus on creating modular architectures. We had standard wire protocols like NFS, RPC, etc. and standard API layers like BSD, POSIX, etc. Those were fun days. You could buy products from different vendors, they actually worked well together and were interchangeable. There were always open source implementations of the standard, but people could also build commercial variations to extend functionality or durability.

    The most successful open source project is Linux. We tend to forget it has very strict APIs and layers. New kernel implementations must often be backed by official standards (USB, SCSI…). Open source and commercial implementations live happily side by side in Linux.

    If we contrast Linux with the state of open source today, we see so many implementations which overlap. Take the big data eco-systems as an example: in most cases there are no standard APIs, or layers, not to mention standard wire protocols. Projects are not interchangeable, causing a much worse lock-in than when using commercial products which conform to a common standard.

  • Open Source Malaria helps students with proof of concept toxoplasmosis pill

    A team of Australian student researchers at Sydney Grammar School has managed to recreate the formula for Daraprim, the drug made (in)famous by the actions of Turing Pharmaceuticals last year when it increased the price substantially per pill. According to Futurism, the undertaking was helped along by an, “online research-sharing platform called Open Source Malaria [OSM], which aims to use publicly available drugs and medical techniques to treat malaria.”

    The students’ pill passed a battery of tests for purity, and ultimately cost $2 using different, more readily available components. It shows the potential of the platform, which has said elsewhere there is, “enormous potential to crowdsource new potential medicines efficiently.” Although Daraprim is already around, that it could be synthesized relatively easily without the same materials as usual is a good sign for OSM.

  • What's the most secure operating system?

    Deciding what operating system (OS) to keep your computer running smoothly—and with the highest level of security—is a controversial yet frequent question many business owners, government officials, and ordinary Joes and Janes ask.

    There are many different operating systems—the software at the base of every computer, controlling the machine's array of functions—like Mac OS10, which comes pre-loaded on Apple laptops and desktops, and Microsoft Windows that's on the majority of personal computers. Google's Android and Apple's iOS for mobile devices are designed specifically for devices with smaller touchscreens.

    Whatever OS you use—and many users are very loyal to their operating system of choice and will argue that their's is the best—it's not entirely secure or private. Hackers are still infiltrating systems every day, and they can easily target victims with malware to spy on users and disable their operating system altogether.

    Because of this, choosing a secure system is essential to staying secure online. Below are the top three secure operating systems that will help users take the next step to ensure proper cyber and hardware security.

  • New IoT Botnet, Attackers Target Tor, and More…

    Firefox’s emergency security patch: If you use Firefox at all, and I’m assuming that most of you do, you might want to run an update to get the latest security patch from Mozilla. The patch was rushed to market on November 30 to fix a zero day vulnerability that was being exploited in the wild to attack the Firefox based Tor browser.

    In a blog post on Wednesday, Mozilla’s security head Daniel Veditz wrote, “The exploit in this case works in essentially the same way as the ‘network investigative technique’ used by FBI to deanonymize Tor users…. This similarity has led to speculation that this exploit was created by FBI or another law enforcement agency. As of now, we do not know whether this is the case. If this exploit was in fact developed and deployed by a government agency, the fact that it has been published and can now be used by anyone to attack Firefox users is a clear demonstration of how supposedly limited government hacking can become a threat to the broader Web.”

    Mesa 12.0.4 is exciting for dozens of bug fixes, including the work to offer better RadeonSI performance. But with Mesa 12.0.4 you don't have the RADV Vulkan driver, OpenGL 4.5, or the other exciting Mesa 13 work.

  • Kernel maintenance, Brillo style

    Brillo, he said, is a software stack for the Internet of things based on the Android system. These deployments bring a number of challenges, starting with the need to support a different sort of hardware than Android normally runs on; target devices may have no display or input devices, but might well have "fun buses" to drive interesting peripherals. The mix of vendors interested in this area is different; handset vendors are present, but many more traditional embedded vendors can also be found there. Brillo is still in an early state of development.

  • Reviewing Project Management Service `Wrike` And Seems Interesting

    I have been testing some services for our project and found this amazing service, thought why not share it with you guys, it might be useful for you. Project management is a term that in some respects appears common, yet in practice still seems to be limited to large companies. While this may be true, the foundations of project management are actually rather simple and can be adopted by anyone, in any industry. One of the major requirements you need to consider when selecting a good project management software is the ability to run and operate it on the go via your mobile devices. Other factors include the ability to access the software from any platform whether it be Linux, Mac, or Windows. This can be achieved when the project management software is web-based. Wrike is a software that does of all this.

    For those who can't live without screen colour shifting technology such as Redshift or f.lux, myself being one of them, using Wayland did pose the challenge of having these existing tools not working with the Xorg replacement. Thankfully, all is not lost and it is possible even right now. Thanks to a copr repo, it's particularly easy on Fedora 25.

    One of the changes that comes with Wayland is there is currently no way for third-party apps to modify screen gamma curves. Therefore, no redshift apps, such as Redshift itself (which I recently covered here) will work while running under Wayland.
