Tiny NanoPi Duo2 SBC offers camera connector

Filed under
Linux
Ubuntu

FriendlyElec has launched a tiny, under $20 “NanoPi Duo2” board that updates the original Duo with an Allwinner H3, Bluetooth, a camera connector, and an optional 2G carrier board.

FriendlyElec has spun out a modest upgrade to last year’s $13 (previously $8) NanoPi Duo. Like the Duo, the COM-like, $19.50 NanoPi Duo2 includes two 16-pin GPIO headers with breadboard pins in a dual-in-line layout.

  • Measuring the speaker frequency response using the AUDMES free software GUI - nice free software

    My current home stereo is a patchwork of various pieces I got on flee markeds over the years. It is amazing what kind of equipment show up there. I've been wondering for a while if it was possible to measure how well this equipment is working together, and decided to see how far I could get using free software. After trawling the web I came across an article from DIY Audio and Video on Speaker Testing and Analysis describing how to test speakers, and it listing several software options, among them AUDio MEasurement System (AUDMES). It is the only free software system I could find focusing on measuring speakers and audio frequency response. In the process I also found an interesting article from NOVO on Understanding Speaker Specifications and Frequency Response and an article from ecoustics on Understanding Speaker Frequency Response, with a lot of information on what to look for and how to interpret the graphs. Armed with this knowledge, I set out to measure the state of my speakers.

    The first hurdle was that AUDMES hadn't seen a commit for 10 years and did not build with current compilers and libraries. I got in touch with its author, who no longer was spending time on the program but gave me write access to the subversion repository on Sourceforge. The end result is that now the code build on Linux and is capable of saving and loading the collected frequency response data in CSV format. The application is quite nice and flexible, and I was able to select the input and output audio interfaces independently. This made it possible to use a USB mixer as the input source, while sending output via my laptop headphone connection. I lacked the hardware and cabling to figure out a different way to get independent cabling to speakers and microphone.

  • Arm Offers Lower Cost Cortex-A5 License

    Arm is now offer a low-cost route to developing Cortex-A5 based Linux-capable ASICs for embedded Internet of Things (IoT) devices featuring advanced edge processing, with a new one-year license fee of $75,000. This fee provides access to the CPU IP and one year of design support, through Arm's DesignStart program.

  • Arm DesignStart program expands to accelerate Linux-based embedded design

    While the breadth of IoT provides endless possibilities for advanced software development, it also holds challenges for designers. In a rapidly changing and competitive market, designers need to differentiate their products and deliver enhanced designs at the lowest cost in the fastest time possible.

    One avenue for differentiation is “rich embedded processing”, which we define at Arm as providing an advanced level of performance and sophistication. Sometimes that includes an interactive user interface, but on the whole, it is about offering advanced capability. These products use a comprehensive set of software stacks and benefit from the breadth of ready-to-run middleware and applications available on fully featured operating systems such as Linux. Companies developing rich embedded IoT designs are now turning toward application-specific integrated circuits (ASICs) to meet their specific needs.

  • OpenShift Commons Briefing: OpenShift 3.11 Release Update with Scott McCarty (Red Hat)

    In this briefing, Red Hat’s Scott McCarty and numerous other members of the OpenShift Product Management team gave an in-depth look at Red Hat’s OpenShift’s latest release 3.11 and some insights in to the road ahead.

  • Awards roll call: Red Hat awards, June to October 2018

    Depending on the weather in your region, it’s safe to say that the seasons are changing so it’s a good time to look back at what was a busy few months for Red Hat, especially when it came to industry awards for our technical and product leadership. In recent months, Red Hat products and technologies took home twenty awards, highlighting the breadth and depth of our product portfolio as well as the expertise that we provide to our customers. In addition, Red Hat as a company won five awards recognizing its growth and culture as a leader in the industry.

  • More advice from a judge - what it takes to win a Red Hat Innovation Award

    Last year I penned the below post to provide insight into what the judges of the Red Hat Innovation Awards are looking for when reviewing submissions. Looking back, I would give almost the identical advice again this year...maybe with a few tweaks.

    With all the stellar nominations that we receive, the question I often get is, “how can we make our entry standout?” There’s no magic formula for winning the Red Hat Innovation Awards, but there are things that the other judges and I look for in the entries.

    Overall, we’re looking for the project that tells a compelling story. It’s not just about sharing what Red Hat products and services you used, we want to hear the full narrative. What challenges did you face; how you implemented the project; and ultimately, what was the true business impact and transformation that took place? Submissions that are able to showcase how open source culture and values were key to success, or how the project is making a difference in the lives of others, are the entries that most often rise to the top.

  • Blockcerts Updates Open Source Blockchain Architecture

    Learning Machine is making changes to its Blockcerts Credential Issuer, Verifier and Wallet to enable native support for records issuance and verification using any blockchain. Blockcerts was launched by Learning Machine and MIT Media Lab in 2016 as new way to allow students to receive digital diplomas through an app, complementing a traditional paper degree.

    Blockcerts was originally designed to be blockchain-agnostic, which means that open standards can be used to anchor records in any blockchain. The Blockcerts Universal Identifier recognizes which blockchain is being used and verifies accordingly. Currently, the open source project has added support for bitcoin and Ethereum blockchains, but anyone can add support through the project's GitHub page.

  • On the low adoption of automated testing in FOSS

    A few times in the recent past I've been in the unfortunate position of using a prominent Free and Open Source Software (FOSS) program or library, and running into issues of such fundamental nature that made me wonder how those issues even made it into a release.

    In all cases, the answer came quickly when I realized that, invariably, the project involved either didn't have a test suite, or, if it did have one, it was not adequately comprehensive.

    I am using the term comprehensive in a very practical, non extreme way. I understand that it's often not feasible to test every possible scenario and interaction, but, at the very least, a decent test suite should ensure that under typical circumstances the code delivers all the functionality it promises to.

    [...]

    Most FOSS projects, at least those not supported by some commercial entity, don't come with any warranty; it's even stated in the various licenses! The lack of any formal obligations makes it relatively inexpensive, both in terms of time and money, to have the occasional bug in the codebase. This means that there are fewer incentives for the developer to spend extra resources to try to safeguard against bugs. When bugs come up, the developers can decide at their own leisure if and when to fix them and when to release the fixed version. Easy!

    At first sight, this may seem like a reasonably pragmatic attitude to have. After all, if fixing bugs is so cheap, is it worth spending extra resources trying to prevent them?

  • Teaching With an Index Card: the Benefits of Free, Open-Source Tools
  • Decentralized Authentication for Self-Sovereign Identities using Name Systems

    The GNU Name System (GNS) is a fully decentralized public key infrastructure and name system with private information retrieval semantics. It serves a holistic approach to interact seamlessly with IoT ecosystems and enables people and their smart objects to prove their identity, membership and privileges - compatible with existing technologies.

    In this report we demonstrate how a wide range of private authentication and identity management scenarios are addressed by GNS in a cost-efficient, usable and secure manner. This simple, secure and privacy-friendly authentication method is a significant breakthrough when cyber peace, privacy and liability are the priorities for the benefit of a wide range of the population.

    After an introduction to GNS itself, we show how GNS can be used to authenticate servers, replacing the Domain Name System (DNS) and X.509 certificate authorities (CAs) with a more privacy-friendly but equally usable protocol which is trustworthy, human-centric and includes group authentication. We also built a demonstrator to highlight how GNS can be used in medical computing to simplify privacy-sensitive data processing in the Swiss health-care system. Combining GNS with attribute-based encryption, we created ReclaimID, a robust and reliable OpenID Connect-compatible authorization system. It includes simple, secure and privacy-friendly single sign-on to seamlessly share selected attributes with Web services, cloud ecosystems. Further, we demonstrate how ReclaimID can be used to solve the problem of addressing, authentication and data sharing for IoT devices.

    These applications are just the beginning for GNS; the versatility and extensibility of the protocol will lend itself to an even broader range of use-cases.

    GNS is an open standard with a complete free software reference implementation created by the GNU project. It can therefore be easily audited, adapted, enhanced, tailored, developed and/or integrated, as anyone is allowed to use the core protocols and implementations free of charge, and to adopt them to their needs under the terms of the GNU Affero General Public License, a free software license approved by the Free Software Foundation.

  • RApiDatetime 0.0.4: Updates and Extensions

    The first update in a little while brings us release 0.0.4 of RApiDatetime which got onto CRAN this morning via the lovely automated sequence of submission, pretest-recheck and pretest-publish.

    RApiDatetime provides seven entry points for C-level functions of the R API for Date and Datetime calculations. The functions asPOSIXlt and asPOSIXct convert between long and compact datetime representation, formatPOSIXlt and Rstrptime convert to and from character strings, and POSIXlt2D and D2POSIXlt convert between Date and POSIXlt datetime. This releases brings asDatePOSIXct as a seventh courtesy of Josh Ulrich. All these functions are all fairly useful, but not one of them was previously exported by R for C-level use by other packages. Which is silly as this is generally extremely carefully written and tested code.

Btrfs To Ship Multiple Performance Improvements In The Next Linux Kernel

Filed under

Adding to the excitement around Linux 4.20~5.0 are now multiple performance improvements to the Btrfs file-system to be presented for this next Linux kernel release.

Btrfs offers a lot of features not readily available by other in-tree Linux file-systems, but even with all of the features like SSD optimizations, its performance hasn't been all that staggering (in part because, yes, it is copy-on-write by default that does hurt some workloads). But come Linux 4.20~5.0, there should be multiple speed-ups to Btrfs.

  • Coreboot's Flashrom Moves On To Flashing AMD GPUs Up Through Polaris

    Last week I wrote about new patches adding Coreboot Flashrom support for Radeon GPUs for being able to re-program the SPI blocks on AMD graphics processors. Initially that was for old Radeon HD 2000 through HD 6000 series hardware but now it's moved onto the GCN world.

    That reverse engineering work for bringing Radeon support to Flashrom is being done by longtime open-source developer Luc Verhaegen who was involved with the RadeonHD driver effort a decade ago. He's continued working on this SPI chip flashing support in his spare time and has got the code working for GCN hardware now -- most Southern/Sea Islands hardware and even now Polaris.

  • WebAssembly’s post-MVP future: A cartoon skill tree

    People have a misconception about WebAssembly. They think that the WebAssembly that landed in browsers back in 2017—which we called the minimum viable product (or MVP) of WebAssembly—is the final version of WebAssembly.

    I can understand where that misconception comes from. The WebAssembly community group is really committed to backwards compatibility. This means that the WebAssembly that you create today will continue working on browsers into the future.

    But that doesn’t mean that WebAssembly is feature complete. In fact, that’s far from the case. There are many features that are coming to WebAssembly which will fundamentally alter what you can do with WebAssembly.

    I think of these future features kind of like the skill tree in a videogame. We’ve fully filled in the top few of these skills, but there is still this whole skill tree below that we need to fill-in to unlock all of the applications.

  • PASE Versus ILE: Which Is Best For Open Source?

    Open source has emerged as a driver of innovation in the past 20 years, and has greatly accelerated technological innovation. The proprietary IBM i platform has also benefited from this trend, thanks in large part to the capability to run Linux applications in the PASE runtime. But some members of the IBM i community are concerned that the fruits of the open source innovation have not tasted quite as sweet as they do on other platforms.

    Linux was the original breakout star in open source software, and so it should be no surprise that the vast majority of software developed with the open source method is designed to run on the Linux operating system and associated open source componentry, including the Apache Web Server, MySQL database, and PHP, the so-called LAMP stack (although you can substitute other pieces, like the Postgres and MariaDB databases and languages like Perl, Python, and Node.js to create other clever acronyms).

    The IBM i operating system can run Linux applications through PASE, the AIX runtime that IBM brought to OS/400 so many years ago. Getting Linux applications to run on PASE requires that they’re first ported to AIX, which is often not too much work, since Linux is a variant of Unix, just like AIX.

  • How Instagram is scaling its infrastructure across the ocean

    To prevent quorum requests from going across the ocean, we're thinking about partitioning our dataset into two parts: Cassandra_EU and Cassandra_US. If European users' data stores are in the Cassandra_EU partition, and U.S. users' data stores are in the Cassandra_US partition, users' requests won't need to travel long distances to fetch data.

    For example, imagine there are five data centers in the United States and three data centers in the European Union. If we deploy Cassandra in Europe by duplicating the current clusters, the replication factor will be eight and quorum requests must talk to five out of eight replicas.

    If, however, we can find a way to partition the data into two sets, we will have a Cassandra_US partition with a replication factor of five and a Cassandra_EU partition with a replication factor of three—and each can operate independently without affecting the others. In the meantime, a quorum request for each partition will be able to stay in the same continent, solving the round-trip latency issue.

  • Two software companies, fed up with Amazon, Alibaba and other big cloud players, have a controversial new plan to fight back

    Every year, large cloud companies like Amazon rake in billions of dollars— but some of their most popular cloud services comes from repackaging software projects created by other, smaller companies.

    Amazon is repackaging what's known as "open source" software, which is software that is given away for free, meaning Amazon has every legal right to use it in this way. For instance, since 2013, Amazon had been offering the open-source database Redis as part of a popular cloud service called ElastiCache.

  • Running Your Own Database-as-a-Service with the Crunchy PostgreSQL Operator

    One reason why enterprises adopt open source software is to help free themselves from vendor lock-in. Cloud providers can offer open source “as-a-service” solutions that allow organizations to take advantage of open source solutions, but this in turn has can create a new type of trap: infrastructure lock-in.

    Many organizations have adopted Kubernetes to give themselves flexibility in where they can deploy their services in the cloud, without being locked into one provider. Some people express concerns that this instead creates “Kubernetes lock-in,” but because Kubernetes is open source and has both widespread support and active development, it should be no different than adopting Linux as your operating system.

  • Linux Apps Coming To MediaTek-Powered Chromebooks Like The Acer R13

    Google made no mention of Linux apps on Chrome OS at last week’s hardware event in New York. I was a little surprised considering the fact that the Pixel Slate and Chrome OS saw nearly as much stage time as the Pixel phone that brought most of the media to Manhattan.

    [...]

    Unfortunately, the Chromebook R13 was quickly overshadowed by new flagships from Samsung and ASUS that featured more powerful processors and various features that made them more appealing to consumers. It was a sad happenstance for the Acer Chromebook because honestly, it is still a great device two years later. Seeing Google bring Linux apps to this device could breath much-needed new life into this model.
