  • Raspberry Pi Sees More Competition With Odroid-N2 Release

    Raspberry Pi's continued success has proven that itty-bitty computers aren't just a fad. That success has attracted a long list of competitors too, and that list grew this week with the official release of Hardkernel's new Odroid-N2 single board computer.
    Hardkernel announced the Odroid-N2 in February. The device comes in two variants: one with 2GB of RAM that costs $63 and one with 4GB that costs $79. Those versions are otherwise identical, so unless someone's looking to minimize costs as much as possible, we suspect most people will spend the extra $16 to double the memory.
    The Odroid-N2 features a big.Little configuration comprised of a quad-core Arm Cortex-A73 CPU locked at 1.8GHz and a dual-core Cortex-A53 clocked at 1.9GHz. Those processors work in conjunction with a Mali-G52 GPU with six execution engines clocked at 846MHz, as well as the DDR4 memory running at 1,320MHz.

  • Open Source in Bangkok

    Next week, Collaborans will be in Bangkok, Thailand, to participate in the 25th edition of Linaro Connect, a bi-annual, week-long gathering of the world's leading open source engineers working on Arm. Tomeu Vizoso and Gustavo Padovan will be in attendance to present Panfrost, the Open Source driver for Arm Mali GPUs.

    On Thursday, April 4, Tomeu will be taking part in the Open Source GPU Drivers BoF to discuss the significant progress around Panfrost. On the following day, April 5, both Tomeu and Gustavo will be taking part in Demo Friday to showcase Panfrost in action, running on a Rockchip RK3288 platform (Chromebook). You can find the details below for both events.

    With a Gallium driver merged in Mesa, and a Linux kernel DRM driver going upstream, Panfrost is now available for Midgard (T-XXX) & Bifrost (G-XX) architectures, with support for EGL and OpenGL ES, as well as Wayland and media playback.

5 Best Free Linux Medical Practice Management Software

tuxmachines.org - Ned, 03/31/2019 - 04:01

Medical Practice Management Software (MPMS) is a type of software that is designed to supervise and support the day-to-day operations of a medical practice. This category of software typically offers functionality such as data entry, scheduling appointments, billing, reporting, records management, the generation of reports, accounting, and capturing patient demographics.

There is often an overlap between MPMS software and Electronic Medical Records systems (EMR). In some cases, a single software application offers both MPMS and EMR functionality. However, there are fundamental differences between the two. Whilst MPMS concentrates on administrative and financial matters, an EMR typically represents an element of a local standalone health information system.

This is the third article in our series covering open source medical software. Our earlier medical articles focused on Electronic Medical Records systems and Medical Imaging software.

To provide an insight into the quality of software that is available, we have compiled a list of 5 hot free Linux Medical Practice Management software.

The 4 best Debian Linux derivatives to check out

tuxmachines.org - Ned, 03/31/2019 - 03:56

The Debian Linux operating system is one of the oldest Linux distributions in history. It’s highly influential and used as a base in some of the most famous Linux operating systems.

Due to how influential Debian is, many derivatives have come on the scene over the years. These spin-offs of Debian borrow the core philosophy of the project but add in a twist, such as a focus on security, ease of use, etc. There are a whole lot of Debian Linux spinoffs out there. It is because of this that, we’ve decided to list off the best ones. So, here are the four best Debian derivatives to check out!

Ultrabook & Bionic - Running Unity

tuxmachines.org - Ned, 03/31/2019 - 03:52

I am quite pleased with this upgrade. With Xenial supported until 2021, Unity is a viable choice, with fixes and updates that will allow you to continue using the desktop environment without issues. It still looks fresh and modern, a sign of good design (sign, design, get it) back in the day. Trusty remains the favorite son, though.

There were no regressions - apart from the Fn keys et al - no software seizure, my data was fully intact, and on top of that, the desktop was rather sprightly. Indeed, if you compare to the netbook experience, there's none of that, on the contrary, but then, the age gap and the price bracket delta make a huge difference. Unity was stable and fast, just the thing that I want in my production environment.

Regardless of how the upcoming Plasma test pans out, I'm very happy. This already gives me a necessary degree of freedom and a sense of solace that I can continue using the Ultrabook without compromises. Good. There. In fact, I might even do a series of combat tests on this box, too, similar to the Slimbook reports. Which brings Plasma into focus. And that shall be the focus of the next article in this little series. Keep your eyelids peeled. Or something.

James Bottomley: A Roadmap for Eliminating Patents in Open Source

tuxmachines.org - Ned, 03/31/2019 - 03:34

The realm of Software Patents is often considered to be a fairly new field which isn’t really influenced by anything else that goes on in the legal lansdcape. In particular there’s a very old field of patent law called exhaustion which had, up until a few years ago, never been applied to software patents. This lack of application means that exhaustion is rarely raised as a defence against infringement and thus it is regarded as an untested strategy. Van Lindberg recently did a FOSDEM presentation containing interesting ideas about how exhaustion might apply to software patents in the light of recent court decisions. The intriguing possibility this offers us is that we may be close to an enforceable court decision (at least in the US) that would render all patents in open source owned by community members exhausted and thus unenforceable. The purpose of this blog post is to explain the current landscape and how we might be able to get the necessary missing court decisions to make this hope a reality.

What is Patent Exhaustion?

Patent law is ancient, going back to Greece in around 500BC. However, every legal system has been concerned that patent holders, being an effective monopoly with the legal right to exclude others, did not abuse that monopoly position. This lead to the concept that if you used your monopoly power to profit, you should only be able to do it once for the same item so that absolute property rights couldn’t be clouded by patents. This leads to something called the exhaustion doctrine: so if Alice holds a patent on some item which she sells to Bob and Bob later sells the same item to Charlie, Alice can’t force Bob or Charlie to give her a part of their sale proceeds in exchange for her allowing Charlie to practise the patent on the item. The patent rights are said to be exhausted with the sale from Alice to Bob, so there are no patent rights left to enforce on Charlie. The exhaustion doctrine has since been expanded to any authorized transfer, even if no money changes hands (so if Alice simply gave Bob the item instead of selling it, the patent still exhausts at that transaction and Bob is still free to give or sell the item to Charlie without interference from Alice).

Of course, modern US patent rights have been around now for two centuries and in that time manufacturers have tried many ingenious schemes to get around the exhaustion doctrine profitably, all of which have so far failed in the courts, leading to quite a wealth of case law on the subject. The most interesting recent example (Lexmark v Impression) was over whether a patent holder could use their patent power to enforce any onward conditions at all for which the US Supreme Court came to the conclusive finding: they can’t and goes on to say that all patent rights in the item terminate in the first authorized transfer. That doesn’t mean no post sale conditions can be imposed, they can by contract or licence or other means, it just means post sale conditions can’t be enforced by patent actions. This is the bind for Lexmark: their sales contracts did specify that empty cartridges couldn’t be resold, so their customers violated that contract by selling the cartridges to Impression to refill and resell. However, that contract was between Lexmark and the customer not Lexmark and Impression, so absent patent remedies Lexmark has no contractual case against Impression, only against its own customers.

Games: Valve and Microsoft

  • Valve are having a rethink with Artifact, no updates due soon as they look to address the major issues

    In a pretty refreshing update from the Artifact team at Valve, they stated they're looking into the major issues with it.

    In my original article posted at release for Artifact, I did mention how I enjoyed the actual gameplay. However, I also mentioned how it could end up costing you a lot of money even though it's not free to play and there was no progression system (at the time). I still think launching without any kind of progression was a huge mistake and the tickets you had to pay for were not good value for money either.

    The game lost players at an alarming rate, something I also covered (#1, #2) and now it's struggling to even keep 400 players on it. Valve certainly aren't stupid though, they do have some incredibly smart developers and it seems they're going to attempt to bring it back to life but this could take a while.

  • Valve have now officially teased their own VR headset with Valve Index

    While details are extremely light, we now know Valve's VR headset is called the Valve Index and more details are coming soon.

  • Valve Is Teasing "Index" - Its Own VR Headset

    While Valve has long been collaborating with HTC and others on VR headsets and other ecosystem work to enhance virtual reality gaming as well as bringing VR support to Linux, the company is finally preparing to release its own high-end VR headset: the Valve Index.

    It's been speculated for months and more that Valve would end up releasing their own VR headset paired with their Knuckles controllers while the wait should finally be over soon... On the Steam Store they are now teasing their own headset dubbed the Valve Index.

  • Minecraft removes references to Notch

    Microsoft, which has owned Minecraft since Notch sold all rights to it for $2.5bn back in 2014, is yet to comment on the decision. But the change feels like it has been a while coming.

  • Minecraft update removes most references to original creator

    The main menu of Minecraft has long been home to a series of rotating phrases of splash text on the top right-hand corner of the logo, which include hundreds of different jokes, catchphrases, and references. But the most recent update to the game has tellingly removed three splash text phrases from the game: “Made by Notch!,” “The Work of Notch!,” and “110813!” (the date that Persson got married).

The Thermal Performance Of NVIDIA's Jetson Nano $99 Developer Board

tuxmachines.org - Sob, 03/30/2019 - 19:25

One of the exciting product launches for this month has been the introduction of the NVIDIA Jetson Nano as a $99 Arm developer board offering four Cortex-A57 cores that isn't too special itself but packing in a 128-core Maxwell NVIDIA GPU makes this board interesting for the price. Out-of-the-box the Jetson Nano is just passively cooled by a small aluminum heatsink, but does it work any better if actively cooled to avoid any potential thermal throttling? Here are some thermal benchmarks.

The Jetson Nano provides a lot of potential for under $100 when using software to leverage both the CPU and GPU with use-cases from building your own robot to DIY appliances or even having a nice hobbyist Arm Linux developer board with some "oomph" to it without spending much money. In time for the launch day earlier this month I didn't have the time to run any thermal tests, but here are those numbers. On launch day I only had a few days experience with the Jetson Nano but since then I have continued running performance benchmarks and it has been running great and without any issues -- also, no thermal issues to speak of, but decided to run some tests including with an active fan attached to see how that would perform.

Security Leftovers

  • Security researcher pleads guilty to [breaking] into Microsoft and Nintendo

    Prosecutors revealed that Clark had gained access to a Microsoft server on January 24th, 2017 using an internal username and password, and then uploaded a web shell to remotely access Microsoft’s network freely for at least three weeks. Clark then uploaded multiple shells which allowed him to search through Microsoft’s network, upload files, and download data.

  • Removing PF

    There have been internal discussions about removing PF from NetBSD. Currently,
    NetBSD's PF is 11 years old, has received no maintenance, and has accumulated
    bugs and vulnerabilities that were fixed upstream but not in NetBSD. The
    latest examples are two vulnerabilities recently discovered in PF, that
    haven't been fixed in NetBSD's PF by lack of interest.

    Importing recent versions of PF in scalable/performant kernels is a huge work
    because of PF's legacy design, and there have been reports that FreeBSD is
    also considering dropping PF.

    Just like other kind of dead wood, NetBSD's PF consumes APIs, makes stuff
    harder to change, and has now reached a point where it is lagging behind
    upstream way too much to still be considered a functional or secure firewall
    on NetBSD.

    NetBSD provides NPF, a clean, secure and scalable firewall, enabled by default,
    that can be used instead, even if it doesn't have all the features PF has
    for now. It is to be noted that IPF too is present in NetBSD, although its
    use is not recommended (for other reasons).

    Given NPF's advanced design and good integration in the NetBSD kernel, trying
    to maintain PF seems like a huge effort for little benefit, and the resources
    would be better spent on NPF.

    Even if we overcame the effort needed to import a new version of PF, we would
    still have to maintain it and regularly synchronize against upstream. Overall,
    it is not viable to keep PF, and has already proven not to be in the past,
    given the state its code finds itself in today.

  • Office Depot slapped with $25m fine over fake malware scans [iophk: "How much money was actually brought in? The fines need to be much larger to make the scam unprofitable."]

    The scans, run in conjuction with partner Support.com, warned customers that their PC was infested with malware and was used to scam them into buying malware removal, security and other software. Support.com was fined $10m for its part.

  • HTTPS Isn't Always As Secure As It Seems

    In analysis of the web's top 10,000 HTTPS sites—as ranked by Amazon-owned analytics company Alexa—the researchers found that 5.5 percent had potentially exploitable TLS vulnerabilities. These flaws were caused by a combination of issues in how sites implemented TLS encryption schemes and failures to patch known bugs, (of which there are many) in TLS and its predecessor, Secure Sockets Layer. But the worst thing about these flaws is they are subtle enough that the green padlock will still appear.

  • Five simple steps to stop your car being stolen by 'keyless' thieves: Insurers pay out a record £1m per DAY due to 'worrying' surge in crime

    The rapid rise in crime has been blamed on keyless cars being exploited. Criminals - who usually operate in pairs - will hold a device up against the car, which captures the signal it sends out to the key.

    This then 'boosts' the signal to another device which relays the signal to the key inside a home.

    The car and key is fooled into thinking they are within the two metre range of operation, which allows the car to be unlocked and started.
