Linux: Hyperledger Fabric 1.0 and LWN Kernel Coverage

Filed under
  • Linux Foundat's Hyperledger Fabric 1.0 Ready For Production
  • [Older but no more paywall] Network acceleration with DPDK

    Network acceleration has always been a subject that naturally attracts the interest of network device vendors and developers. Kernel network acceleration techniques that require, for example, the caching of kernel networking data structures inside the network driver (or maintaining a private modified kernel for a specific device) are naturally frowned upon and bound to be rejected by the kernel networking community. There are also user-space kernel-bypass solutions, including the Data Plane Development Kit (DPDK).

    Among the most popular open-source projects providing user-space network acceleration are Snabb, netmap, and DPDK. With the recent announcement by Jim Zemlin this April that DPDK project has moved to the Linux Foundation, it seems that this is a good time to get an overview of the current status of this project and its roadmap.

  • [Older but no more paywall] Namespaced file capabilities

    The kernel's file capabilities mechanism is a bit of an awkward fit with user namespaces, in that all namespaces have the same view of the capabilities associated with a given executable file. There is a patch set under consideration that adds awareness of user namespaces to file capabilities, but it has brought forth some disagreement on how such a mechanism should work. The question is, in brief: how should a set of file capabilities be picked for any given user namespace?

  • [Older but no more paywall] Some 4.12 development statistics

    Linus Torvalds released the 4.12 kernel on July 2, marking the end of one of the busiest development cycles in the kernel project's history. Tradition requires that LWN publish a look at this kernel release and who contributed to it. 4.12 was, in many ways, a fairly normal cycle, but it shows the development community's continued growth.

    The 4.12 kernel includes 14,821 non-merge changesets contributed by 1,825 developers. That is not the highest changeset count we've ever seen — 4.9 is likely to hold that record for some time — but it comes in at a solid #2. The 4.12 kernel did set a new record for the number of developers participating and for the number of first-time contributors (334), though. This was also a significant release for the growth of the kernel code base: 4.12 has just over one million lines of code more than its predecessor.

Why Is Docker So Popular? Explaining the Rise of Containers and Docker

Filed under

By now, you've almost certainly heard of Docker containers. You know Docker is massively popular. But do you know why? Here's a look at the factors driving tremendous interest in Docker today.

Before delving into a discussion of the factors behind Docker's popularity, it's worth noting that Docker is not the only container platform out there. Nor was it the first to come along.

Other frameworks, like OpenVZ and LXC, were available starting in the mid-2000s. Other container-like technologies, such as FreeBSD jails, go back even further. Docker was released only in 2013, making it a very young technology compared to most of today's mainstream enterprise technologies.

Curiously, however, it was Docker, not a more mature container platform, that has risen to massive prominence over the past few years. That's an outcome worth pondering -- for the purposes both of understanding what makes containers in general so popular, as well as why Docker in particular has succeeded so spectacularly, whereas alternative container frameworks have seen little adoption.

  • All Systems Go! - The Userspace Linux Conference

    At Kinvolk we spend a lot of time working on and talking about the Linux userspace. We can regularly be found presenting our work at various events and discussing the details of our work with those who are interested. These events are usually either very generally about open source, or focused on a very specific technology, like containers, systemd, or ebpf. While these events are often awesome, and absolutely essential, they simply have a focus that is either too broad, or too specific.

Security: CIA Cracks Android, Kaspersky Shunned, Slackware Patch for Proprietary Software

Filed under
  • Highrise

    Today, July 13th 2017, WikiLeaks publishes documents from the Highrise project of the CIA. HighRise is an Android application designed for mobile devices running Android 4.0 to 4.3. It provides a redirector function for SMS messaging that could be used by a number of IOC tools that use SMS messages for communication between implants and listening posts. HighRise acts as a SMS proxy that provides greater separation between devices in the field ("targets") and the listening post (LP) by proxying "incoming" and "outgoing" SMS messages to an internet LP. Highrise provides a communications channel between the HighRise field operator and the LP with a TLS/SSL secured internet communication.

Red Hat CTO Chris Wright and Demand for Mobile Applications

  • Innovation fuels open source, but focus gets it to the finish line

    When open source works, like Linux, it becomes a powerful platform that drives innovation across multiple areas, from applications to hardware and even security, where the open source community becomes an asset rather than a liability because they help identify vulnerabilities and fixing them as a community, according to Wright. Further, the emergence of mid-stream organisations like OPNFV now brings together different open source projects, making them accessible by users, and creating environments no only for collaborations, but solutions integration and testing, he adds.

  • The convergence of open source, 5G and service providers

    The open source community, 5G standardisation and service providers are converging towards a singular goal. As Red Hat CTO Chris Wright explains, open source networking projects are now developing the core technologies necessarily for 5G, which has articulated the same requirements for an agile infrastructure capable of support multiple application types.

    And while there is still a gap between open source developed technologies and formal standardisation for 5G, the solutions themselves are rapidly becoming mainstream within service provider environments.

  • Do you prefer tabs or spaces?

    Tabs versus spaces: What seems like an age-old debate in the development community has seen renewed interested in the past several weeks as a report came out from Stack Overflow revealing that developers who use spaces may make more money than those who use tabs. Who knew that indentation style could have such a big impact on you, personally?

  • Dangerous Logic - De Morgan & Programming

    Programmers are master logicians - well they sometimes are. Most of the time they are as useless at it as the average joe. The difference is that the average joe can avoid logic and hence the mistakes. How good are you at logical expressions and why exactly is Augustus De Morgan your best friend, logically speaking?

  • Fundamentals of graph databases with Neo4j
  • Is every build system using Ninja just as fast as every other?

    One of the most common arguments against Meson is that "it is only fast because it uses Ninja rather than Make, using any other Ninja build generator would be just as fast". This is always stated as fact without any supporting evidence or measurements. But is this really the case? Let's find out.

    For testing one needs a project that has both CMake and Meson build definitions. I'm not aware of any so I created one myself. I took the source code of the Mediascanner 2 project, which is using CMake and converted it to use Meson. This project was chosen solely based on the fact that I wrote the original CMake definitions ages ago so I should have a fairly good understanding of the code base. The project itself is a fairly typical small-to-medium project written in C++ with a handful of system dependencies.

  • JavaScript spec gets strung out on padding

    ECMAScript 2017, the latest edition of the specification upon which JavaScript is based, plugs a gap left by awkward extinction of some Node.js code last year.

10 Raspberry Pi HATs: One for Every Occasion

Filed under

The large ecosystem of add-on boards is a key factor in the success of the Raspberry Pi, which torched the competition in our recent hacker board reader survey. Much of the Pi add-on business has moved to the Raspberry Pi Foundation’s HAT (Hardware Attached on Top) I/O specification, which launched in 2014 as an easier, more standardized way to extend the Pi’s 40-pin expansion connector.

Below is a roundup of 10 of the most interesting and highly regarded HATs on the market. This is not a review, but rather a selection intended to reflect the amazing diversity of Pi HATs. We have skipped numerous application segments here, especially in the purely industrial market and in basic accessories like touchscreens and cameras. It should also be noted that there are many excellent Pi add-ons that do not follow the HAT specification.

Compared to traditional Pi add-ons or shields, HATs, which are often called bonnets in the UK, are automatically recognized by the SBC. With the help of a pair of I2C EEPROM pins, the HAT works with the Pi to automatically configure the GPIOs and drivers. The 65x56mm HAT daughter-cards stack neatly on top of the SBC next to the Ethernet and USB ports. This reduces cable clutter and allows both Pi and HAT to fit into standard enclosures. HATs also provide mounting holes that match up with the standard RPi B+, 2, and 3.

Rock64 Mini PC Is The Linux-running Raspberry Pi Killer You’ve Been Waiting For

Filed under

You might be knowing that Raspberry Pi is a small palm sized computer that lets you perform certain tasks and it even has the capability to replace a basic computer. Recently, a developer even took up the task to use a Raspberry Pi 3 as his primary computer after losing his MacBook Pro at a laptop. Just in case you wish to get started with Pi, follow our getting started with Raspberry Pi guide.

Coming back to Rock64, sold by Pine64, it’s a new Raspberry Pi competitor that lets you run 4K videos by spending $25 only; that’s cheaper that a Pi 3. Apart from the 4K playback at 60Hz, Rock64 also beats Raspberry Pi when it comes to supporting HDR10, via HDMI 2.0.

  • Encrypted Media Extensions on the World Wide Web

    Before I continue, I want you to fully realize that with Slackware Linux, your rights are not taken away. You are free to use – or not use – technologies that allow you to watch “protected” content like Netflix videos. Our browsers will work just as well if you choose not to use DRM technologies. The libraries which implement the DRM layer are separate from the Slackware packages containing the browsers (Firefox, Chromium) and are not distributed with the OS. It is up to you to add DRM extensions if you need them. You are and remain in control of your OS.

    Five days ago, the World Wide Web Consortium announced that it would go ahead with its project of making DRM for web-video, and that the Director, Tim Berners-Lee had overruled or decided not to act further on all objections about the dangers this posed to legitimate and important activities including security audits, accessibility adaptation and competition.

    The W3C has an appeals process, which has never been successfully used in W3C history. If 5 percent of the members appeal a decision by the Director, all members are entitled to vote, and if there's a majority in favor of overulling the Director, the decision is unmade.

  • Fedora Developers Begin Talking About Their 28 & 29 Releases For 2018

    While Fedora 26 just shipped yesterday, developers are already talking about their very early release estimates for Fedora 28 and Fedora 29 in 2018.

    The Fedora 27 schedule has been firmed up for a while now and puts the change checkpoint completion deadline on 1 August, beta freeze on 5 September, beta release on 26 September, and the estimated release date for Fedora 27 at 24~31 October.

    Fedora Project Leader Matthew Miller has now laid out "super drafty" release schedules for F28 and F29 based on the fact they like early May and late October releases. The May/October cadence allows them to avoid major public holidays while also being timed nicely around GNOME releases, GCC updates in the spring, etc. They try to hit these targets, but release delays often interfere.
