  • Atom Installer

    One thing that I miss about using Ubuntu is PPA’s there are lot’s of PPA in Ubuntu and you can hack around and install all types of software which are required for your usage.

    In the Fedora side of the world there are copr repos but they don’t have as many repos as in Ubuntu and you can’t build non-free software (don’t get me wrong here, I love FREEdom software but couldn’t resist not using some beautiful non-free applications such as Sublime). I am creating a work around for this by using shell scripts which are open source (cc0) but when those scripts are executed they install non-free software on your system.

  • IOTA: IoT revolutionized with a Ledger

    Ever since the introduction of digital money, the world quickly came to realize how dire and expensive the consequences of centralized systems are. Not only are these systems incredibly expensive to maintain, they are also “single points of failures” which expose a large number of users to unexpected service interruptions, fraudulent activities and vulnerabilities that can be exploited by malicious hackers.

    Thanks to Blockchain, which was first introduced through Bitcoin in 2009, the clear benefits of a decentralized and “trustless” transactional settlement system became apparent. No longer should expensive trusted third parties be used for handling transactions, instead, the flow of money should be handled in a direct, Peer-to-Peer fashion. This concept of a Blockchain (or more broadly, a distributed ledger) has since then become a global phenomenon attracting billions of dollars in investments to further develop the concept.

  • Return Home and Unify: My Case for Unity 8
  • Can netbooks be cool again?

    Earlier this week, my colleague Chaim Gartenberg covered a laptop called the GPD Pocket, which is currently being funded on Indiegogo. As Chaim pointed out, the Pocket’s main advantage is its size — with a 7-inch screen, the thing is really, really small — and its price, a reasonable $399. But he didn’t mention that the Pocket is the resurrection of one of the most compelling, yet fatally flawed, computing trends of the ‘00s: the netbook. So after ten years, are netbooks finally cool again? That might be putting it too strongly, but I’m willing to hope.

  • Compact, rugged module runs Linux or Android on Apollo Lake

    Ubiqcomm’s 95 x 95mm, Apollo Lake-based “COM-AL6C” COM offers 4K video along with multiple SATA, USB, GbE, and PCIe interfaces, plus -40 to 85°C operation.

    Ubiqconn Technology Inc. has announced a “COM-AL6C” COM Express Type 6 Compact form factor computer-on-module built around Intel’s Apollo Lake processors and designed to withstand the rigors of both fixed and mobile industrial applications. The module offers a choice among three Intel Apollo Lake processors: the quad-core Atom x5-E3930, quad-core x5-E3940, and dual-core x7-E3950, which are clocked at up to 2.0GHz burst and offer TDPs from 6.5 to 12 Watts.

  • Internet-enable your microcontroller projects for under $6 with ESP8266

    To get started with IoT (the Internet of Things), your device needs, well, an Internet connection. Base Arduino microcontrollers don't have Internet connectivity by default, so you either need to add Ethernet, Wi-Fi shields, or adapters to them, or buy an Arduino that has built-in Internet connectivity. In addition to complexity, both approaches add cost and consume the already-precious Arduino flash RAM for program space, which limits what you can do.

    Another approach is to use a Raspberry Pi or similar single-board computer that runs a full-blown operating system like Linux. The Raspberry Pi is a solid choice in many IoT use cases, but it is often overkill when all you really want to do is read a sensor and send the reading up to a server in the cloud. Not only does the Raspberry Pi potentially drive up the costs, complexity, and power consumption of your project, but it is running a full operating system that needs to be patched, and it has a much larger attack surface than a simple microcontroller. When it comes to IoT devices and security, simpler is better, so you can spend more time making and less time patching what you already made.

  • 1.8 Billion Mobile Internet Users NEVER use a PC, 200 Million PC Internet Users never use a mobile phone. Understanding the 3.5 Billion Internet Total Audience

    As I am working to finish the 2017 Edition of the TomiAhonen Almanac (last days now) I always get into various updates of numbers, that remind me 'I gotta tell this story'.. For example the internet user numbers. We have the December count by the ITU for year 2016, that says the world has now 3.5 Billion internet users in total (up from 3.2 Billion at the end of year 2015). So its no 'drama' to know what is 'that' number. The number of current internet total users is yes, 3.5 Billion, almost half of the planet's total population (47%).

  • Rewriting the history of free software and computer graphics

    Do you remember those days in the early nineties when most screensavers were showing flying 3D metallic logotypes? Did you have one?

    In this article, I want to go back in time and briefly revise the period in the history of computer graphics (CG) development when it transitioned from research labs to everyone's home computer. The early and mid-1990s was the time when Aldus (before Adobe bought the company) was developing PageMaker for desktop publishing, when Pixar created ToyStory, and soon after 3D modeling and animation software Maya by Alias|Wavefront (acquired by Autodesk). It was also a moment when we got two very different models of CG development, one practiced by the Hollywood entertainment industry and one practiced by corporations like Adobe and Autodesk.

    By recalling this history, I hope to be able to shed new light on the value of free software for CG, such as Blender or Synfig. Maybe we can even re-discover the significance of one implicit freedom in free software: a way for digital artists to establish relations with developers.

    [...]

    The significance of free software for CG

    On the backdrop of this history, free software like Blender, Synfig, Krita, and other projects for CG gain significance for several reasons that stretch beyond the four freedoms that free software gives.

    First, free software allows the mimicking of the Hollywood industry's models of work while making it accessible for more individuals. It encourages practice-based CG development that can fit individual workflows and handle unexpected circumstances that emerge in the course of work, rather than aiming at a mass product for all situations and users. Catering to an individual's needs and adaptations of the software brings users work closer to craft and makes technology more human. Tools and individual skill can be continuously polished, shaped, and improved based on individual needs, rather than shaped by decisions "from above."

  • ONF unveils Open Innovation Pipeline to counter open source proprietary solutions

    ONF and ON.Lab claim the OIP initiative to bolster open source SDN, NFV and cloud efforts being hampered by open source-based proprietary work.

    Tapping into an ongoing merger arrangement with Open Networking Lab, the Open Networking Foundation recently unveiled its Open Innovation Pipeline targeted at counteracting the move by vendors using open source platforms to build proprietary solutions.

  • [FreeDOS] The readability of DOS applications

    Web pages are mostly black-on-white or dark-gray-on-white, but anyone who has used DOS will remember that most DOS applications were white-on-blue. Sure, the DOS command line was white-on-black, but almost every popular DOS application used white-on-blue. (It wasn't really "white" but we'll get there.) Do an image search for any DOS application from the 1980s and early 1990s, and you're almost guaranteed to yield a forest of white-on-blue images like these:

  • More about DOS colors

    In a followup to my discussion about the readability of DOS applications, I wrote an explanation on the FreeDOS blog about why DOS has sixteen colors. That discussion seemed too detailed to include on my Open Source Software & Usability blog, but it was a good fit for the FreeDOS blog.

  • Building a $4 billion company around open source software: The Cloudera story

    Dr Amr Awadallah is the Chief Technology Officer of Cloudera, a data management and analytics platform based on Apache Hadoop. Before co-founding Cloudera in 2008, Awadallah served as Vice President of Product Intelligence Engineering at Yahoo!, running one of the very first organizations to use Hadoop for data analysis and business intelligence. Awadallah joined Yahoo! after the company acquired his first startup, VivaSmart, in July 2000.

    With the fourth industrial revolution upon us—where the lines between the physical, digital and biological spheres are blurred by the world of big data and the fusion of technologies—Cloudera finds itself among the band of companies that are leading this change. In this interview with Enterprise Innovation, the Cloudera co-founder shares his insights on the opportunities and challenges in the digital revolution and its implications for businesses today; how organizations can derive maximum value from their data while ensuring their protection against risks; potential pitfalls and mistakes companies make when using big data for business advantage; and what lies beyond big data analytics.

  • What we (think we) know about meritocracies

    "Meritocracy," writes Christopher Hayes in his 2012 book Twilight of the Elites, "represents a rare point of consensus in our increasingly polarized politics. It undergirds our debates, but is never itself the subject of them, because belief in it is so widely shared." Meritocratic thinking, in other words, is prevalent today; thinking rigorously about meritocracy, however, is much more rare.

  • A new perspective on meritocracy

    Meritocracy is a common element of open organizations: They prosper by fostering a less-hierarchical culture where "the best ideas win." But what does meritocracy really mean for open organizations, and why does it matter? And how do open organizations make meritocracy work in practice? Some research and thinking I've done over the last six months have convinced me such questions are less simple—and perhaps more important—than may first meet the eye.

  • Three new FOSS umbrella organisations in Europe

    So far, the options available to a project are either to establish its own organisation or to join an existing organisation, neither of which may fit well for the project. The existing organisations are either specialised in a specific technology or one of the few technology-neutral umbrella organisations in the US, such as Software in the Public Interest, the Apache Software Foundation, or the Software Freedom Conservancy (SFC). If there is already a technology-specific organisation (e.g. GNOME Foundation, KDE e.V., Plone Foundation) that fits a project’s needs, that may well make a good match.

  • ESA affirms Open Access policy for images, videos and data / Digital Agenda

    ESA today announced it has adopted an Open Access policy for its content such as still images, videos and selected sets of data.

    For more than two decades, ESA has been sharing vast amounts of information, imagery and data with scientists, industry, media and the public at large via digital platforms such as the web and social media. ESA’s evolving information management policy increases these opportunities.

    In particular, a new Open Access policy for ESA’s information and data will now facilitate broadest use and reuse of the material for the general public, media, the educational sector, partners and anybody else seeking to utilise and build upon it.

A volume consists of two parts: file system metadata and the actual blocks containing data in a file.

Reddit: Has anyone here used Linux to create a Dropbox cache (using the LAN Sync feature)? [X-Post /r/Raspberry_Pi]

Tuesday 21st of February 2017 07:55:59 AM

I'm volunteering for an organization with a very spotty internet connection. They have five or so computers that all use Dropbox for file sync. Do you think they would benefit from a Raspberry Pi hooked up via Ethernet that's also syncing the Dropbox client, to increase the chance of the LAN Sync feature having a local copy of files? SD flash storage might help out sync speeds, but I don't want to add to inter-network traffic too much...

Thanks for your thoughts!

Reddit: Does linux / do any linux distros utilize "fast boot" / hybrid boot?

Tuesday 21st of February 2017 05:51:58 AM

Recently someone posted a neat question in ELI5 about how a computer restarts itself. /u/capn_hector gave a thorough response which took this interesting tangent:

"one interesting aspect of modern OSs is they never really "shut down". It used to be that when you shut your computer down all the operating system internal code (the kernel) would have to be re-initialized from scratch. This takes a really long time, several seconds even on a fast computer. So modern OSs (Windows 8 and up) will actually write the kernel's state to disk before they shut down. Then they will just load the kernel state from disk rather than set everything up from scratch. This is the "Fast Boot" mode, officially called Hybrid Boot because it's a hybrid of a shutdown and a hibernate."

Is this a feature used by any (all?) linux distros?

Security Leftovers

  • Java and Python FTP attacks can punch holes through firewalls
    The Java and Python runtimes fail to properly validate FTP URLs, which can potentially allow attackers to punch holes through firewalls to access local networks. On Saturday, security researcher Alexander Klink disclosed an interesting attack where exploiting an XXE (XML External Entity) vulnerability in a Java application can be used to send emails.
  • Microsoft: no plans to patch known bugs before March [Ed: Microsoft is keeping open 'back doors' that are publicly known about, not just secret ones]
    Microsoft has no plans to issue updates for two vulnerabilities, one a zero-day and the other being one publicised by Google, before the scheduled date for its next round of updates rolls around in March. The company did not issue any updates in February, even though it had been scheduled to switch to a new system from this month onwards. It gave no reason for this, apart from saying: "This month, we discovered a last minute issue that could impact some customers and was not resolved in time for our planned updates today. "After considering all options, we made the decision to delay this month’s updates. We apologise for any inconvenience caused by this change to the existing plan." The Google-disclosed bug was made public last week, and is said to be a flaw in the Windows graphic device interface library that can be exploited both locally and remotely to read the contents of a user's memory.
  • Microsoft issues critical security patches, but leaves zero-day flaws at risk
    Microsoft has patched "critical" security vulnerabilities in its browsers, but has left at least two zero-day flaws with public exploit code. The software giant released numerous patches late on Tuesday to fix flaws in Adobe Flash for customers using Internet Explorer on Windows 8.1 and later, as well as Edge for Windows 10.

Red Hat News

  • Why upstream contributions matter when developing open source NFV solutions.
    When software is developed using open source methods, an upstream repository of the code is accessible to all members of the project. Members contribute to the code, test it, write documentation and can create a solution from that code to use or distribute under license. If an organization follows the main stream or branch of the upstream code their solution will receive all the changes and updates created in the upstream repository. Those changes simply “flow down” to the member’s solution. However, if a member organization forks the code — if they create a solution that strays from the main stream — their solution no longer receives updates, fixes and changes from the upstream repository. This organization is now solely responsible for maintaining their solution without the benefit of the upstream community, much like the baby salmon that took a tributary and then have to fend for themselves rather than remain in the main stream and receive the benefit and guidance of the other salmon making their way to the ocean.
