  • Software Defined Drones and the Path to Standardization and Scale in the Drone Industry

    Sartori is the co-founder of Auterion – they’re the Red Hat of the drone industry, serving as a distributor and enabler for open source software for drones. He’s a proponent of open source, and a believer that open source software is the key to scalability in the drone industry. There’s data and history to support the idea. As drone manufacturing giant DJI is often compared to Apple, open source drones are frequently compared to Android – and Sartori points out that Android is based on open source Linux, and as more than 87 percent of phones are now Android, that makes it the most used software in the world.

  • ITP Renewables releases free open-source modelling platform for the energy transition

    ITP Renewables has released Version 1 of open-CEM, a free of charge open source modelling tool for the National Electricity Market (NEM).

  • OpenLeg – The Open Source Robot Leg

    There’s an old saying about standing on the shoulders of giants, but how about doing so with an open source leg? Well, your robots might do so at least, thanks to OpenLeg, a new open source project for building robot legs. Created by [Joey Byrnes], this started out as a senior project for a course at the University of Illinois. The idea is to create a robot leg that others can use to build four-legged robots that can amble around the neighborhood, much like those built by Boston Dynamics.

  • New microscopes unravel the mysteries of brain organization

    The secret of capturing exquisite brain images with a new generation of custom-built microscopes is revealed today in Nature Methods. The new microscopes, known as mesoSPIMs, can image the minute detail of brain tissue down to individual neurons that are five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, faster than ever before. MesoSPIMs provide new insights into brain and spinal cord organization for researchers working to restore movement after paralysis or to investigate neuronal networks involved in cognition, pleasure, or drug addiction.

  • New open-source microscope may help paralysis patients

    Scientists have developed a new generation of custom-built microscopes that significantly improve brain tissue imaging, an advance that could help find better treatment for patients with paralysis.

    The microscopes, known as mesoSPIMs—short for 'mesoscale selective plane-illumination microscopes'—can image brain tissues down to the minute details of individual neurons which are five times thinner than a human hair, the study noted.

    The researchers added that they can uncover the 3D anatomy of entire small organs, faster than ever before using the new microscope.

  • Falco founder: Kubernetes security has to do better than “don’t worry – OH MY GOD”

    It’s almost a year since Sysdig’s behavioral activity monitoring tool Falco entered the sandbox of the Cloud Native Computing Foundation (CNCF). We talked to the company’s new chief open source advocate Kris Nova and co-founder Loris Degioanni to check in about the project’s progress and talk about the state of Kubernetes security and open source licensing in general.

    Falco was first introduced to the public back in May 2016. It’s no secret that security wasn’t exactly a top priority when Kubernetes was developed, so Falco was set up to tackle some of the challenges the orchestrator introduced to the modern infrastructure stack.

    [...]

    Moving the project into the CNCF in October 2018 was the logical next step for Degioanni. “In order to be cloud-native and to actually be placed as a part of the stack of the next generation of infrastructures, you want to be part of the CNCF nowadays.”

    But the foundation has strict rules on what projects must do to make it to the next stage, so the first months in the sandbox were mostly spent setting up processes and work on Falco’s own infrastructure. With Nova, who spent quite some time on the Kubernetes project, now on board, this trajectory is likely to continue.

Additionally, the proportion of Elite performers (highest performing teams) nearly tripled from last year, showing that DevOps capabilities are driving performance.

  • The Internet Relies on People Working for Free

    When you buy a product like Philips Hue’s smart lights or an iPhone, you probably assume the people who wrote their code are being paid. While that’s true for those who directly author a product’s software, virtually every tech company also relies on thousands of bits of free code, made available through “open-source” projects on sites like GitHub and GitLab.

    Often these developers are happy to work for free. Writing open-source software allows them to sharpen their skills, gain perspectives from the community, or simply help the industry by making innovations available at no cost. According to Google, which maintains hundreds of open-source projects, open source “enables and encourages collaboration and the development of technology, solving real-world problems.”

  • What does upstream and downstream development even mean?

    If you've ever dealt with (in any shape or form) open source software, chances are pretty good you've heard the terms upstream and downstream. These terms are actually more important to open source development than you might think.

    But what do they even mean?

    I'm going to explain it to you.

  • Developer pulls critical code from tech company after ICE contract revealed

    On Thursday, software engineer Seth Vargo pulled his open source “Chef Sugar” project from Github, as well as the Ruby package library, RubyGems. Vargo made the decision to pull the code, which had millions of downloads, after learning that Chef, a company that provides an “automation platform” for infrastructure management, had a software contract with ICE.

  • Microsoft poses threat to Germany's digital sovereignty, warns study

    Germany's ministry of the interior asked management consultancy PricewaterhouseCoopers, or PwC, to produce a "Strategic market analysis on reducing dependence on single software providers".

    In the 34-page document released yesterday, researchers conclude that "at all levels" the German government is "strongly dependent" on very few software providers.

    And that is particularly true for Microsoft, whose Office and Windows programs are running on 96% of public officials' computers.

    This dependence results in "pressure points in the federal government, that work in opposition to the government's [stated] strategic IT goals," the report notes. Concerns about information security at Microsoft could "endanger the country's digital sovereignty".

  • Chef roasted for tech contract with family-separating US immigration, forks up attempt to quash protest

    DevOps darling Chef had a nightmare Thursday after it emerged the software biz had inked a deal with US immigration, which sparked protest and a baffling counter-response.

    Here's how it went down. Earlier this week, Chef, an app configuration specialist, was publicly called out for selling $95,000 (£75,000) of licenses to Uncle Sam's Immigration and Customs Enforcement, the controversial agency best known for its recent hits I Separated Asylum-Seeking Families At The Border and What's A Concentration Camp. The one-year software supply deal, brokered by a reseller, kicked off in August.

    Open-source programmer and DevOps guru Seth Vargo, deeply unhappy with this arrangement, yanked offline some of his Ruby Gems – software packages for Ruby devs – that made Ruby-based Chef a lot easier to use. In particular, he took down the popular and useful Chef-Sugar, which over the years has racked up more than 20 million downloads.

  • Thwarting Digital Ad Fraud at Scale: An Open Source Experiment with Anomaly Detection

    To achieve the requisite capabilities while keeping the experimental solution cost-effective for practical usage, our test system used an architecture comprised of open source Apache Kafka, Apache Cassandra, and our Anomaly Detection application. Beyond the performance, scalability, and affordably Kafka and Cassandra provide, both Open-source data technologies also offer a particularly high degree of compatibility and pair well together.

  • A Developer Deletes His Code to Protest Its Use by ICE

    Computer server management software is usually pretty boring. But when that software is sold to a federal agency that separates families and detains children, even esoteric technology can become the center of controversy.

    On Monday, activist Shanley Kane highlighted a contract between Seattle-based software company Chef and US Immigration and Customs Enforcement. Chef develops and sells open source software for configuring servers and cites Alaska Airlines, Google, Facebook, and Capital One as customers.

    The ICE contract created a minor stir on Twitter, but by Thursday morning, Chef hadn’t made a public statement about the controversy. Discouraged by the company’s silence, former Chef employee Seth Vargo removed several Chef-related open source tools that he had hosted on two code repositories. They included Sugar, a tool designed to make it easier to work with Chef’s software that’s widely used by Chef customers, though it’s not clear if ICE uses it. "I have removed my code from the Chef ecosystem," Vargo wrote on the code hosting site GitHub. "I have a moral and ethical obligation to prevent my source [code] from being used for evil."

  • Open-source control system alternatives

    Though the Open Process Automation Forum (OPAF) continues to receive the lions share of coverage as defining “the” open system, it is, in fact, not the only approach or option for the application of open technologies for the control domain.

    OPAF is somewhat constrained on how open they can be because they have backwards compatibility as a starting point, which to some extent limits them to using traditional and “less open” (consortia-sponsored) protocols such as OPC, FieldComm, Profibus, etc. to ensure compatibility and vendor support. They’re also working on how to convert all their existing applications and IP to the new virtual environment.

    [...]

    Building on the latent momentum for small, low-cost microcontrollers, Hilscher has introduced its Industrial Raspberry Pi 3 using Node-Red as the development/integration environment and Docker containers to design and connect with the rest of the world.

    Node-RED is a Java-script programming tool for connecting hardware devices, APIs and online services by providing a browser-based flow editor that makes it easy to virtually “wire” together flows that can be then deployed to the runtime in a single click.

  • When was the last time you used Windows?

    Are friends and family constantly asking you to troubleshoot issues with their Windows or Mac device? Being the resident support technician in your home is an important job. Like any responsible technology steward, you are going to try your best to help out. However, it might be quite a challenge if it has been a while since you last used such an operating system.

    How long has it been since you last used Windows? Before using Linux, were you primarily a Mac user? Or, are you using Windows or Mac now either at home or work?

    Take our poll by selecting the Windows version you last remember using. If the term, "windows" only reminds you of those glass panels that let sunlight inside, you are probably a long-time Linux user.

  • Attempting to install Linux on a new laptop, a follow-up

    I recently detailed my attempts to install Linux as an alternative boot an SD card in a new Dell laptop. Those attempts failed. See Attempting to install Linux on a new laptop for the details.

    Microsoft has continued in their usual way and notified me last week that the current feature update of Windows on that laptop would soon be unsupported and urged me to update to the latest version.

    However, that proved impossible. In spite of removing most of the software installed on the machine, Windows was incapable of cleaning up enough disk space to allow the installation of Windows 10 version 1903 to proceed. The installed 32GB eMMC drive simply is no longer large enough to allow the updates to install. This was true even when I manually downloaded the update and tried to install from an external drive.

    It is remotely possible wiping the hard drive and performing a clean install might have worked, but the prospect of being forced to do so every year was not appealing. So being forced to choose between running an out of date version of Windows or wiping the hard drive and installing Linux, I chose to try the latter.

    Tools like error monitoring, crash reporting, and performance monitoring are tools to help you create a better user experience and are fast becoming crucial tools for web development and site reliability. But really what are they? And when do you need them?

    You've built a cool web app or service, and you want to make sure your customers have a great experience.

    You know I advocate for utilizing automated tests so you find bugs before your customers do. However, fast development lifecycles, and quickly reacting to customer needs is a good thing, and we all know that complete testing is not possible. That's why I firmly believe that site monitoring tools like logging, crash reporting, performance monitoring, etc are awesome for maintaining and improving user experience.

  • Porting Storm to Python 3

    We released Storm 0.21 on Friday (the release announcement seems to be stuck in moderation, but you can look at the NEWS file directly). For me, the biggest part of this release was adding Python 3 support.

    Storm is a really nice and lightweight ORM (object-relational mapper) for Python, developed by Canonical. We use it for some major products (Launchpad and Landscape are the ones I know of), and it’s also free software and used by some other folks as well. Other popular ORMs for Python include SQLObject, SQLAlchemy and the Django ORM; we use those in various places too depending on the context, but personally I’ve always preferred Storm for the readability of code that uses it and for how easy it is to debug and extend it.

    It’s been a problem for a while that Storm only worked with Python 2. It’s one of a handful of major blockers to getting Launchpad running on Python 3, which we definitely want to do; stoq ended up with a local fork of Storm to cope with this; and it was recently removed from Debian for this and other reasons. None of that was great. So, with significant assistance from a large patch contributed by Thiago Bellini, and with patient code review from Simon Poirier and some of my other colleagues, we finally managed to get that sorted out in this release.

However, certain optional features are not currently supported like Tiled Resources, Conservative Rasterization and Rasterizer Ordered Views but they may be added if ever needed. This should fix a crashing issue with Plants vs Zombies - Battle for Neighborville, which requires at least D3D 11.3.

    Additionally, support for DXGI (Microsoft DirectX Graphics Infrastructure) was boosted up to version 1.5 which allows applications/games to check for HDR support but DXVK itself does not currently support HDR. Some games seem to need the interface for HDR to be there even if not used. You should also find the Rockstar Game Launcher working better with this update to DXVK, with new support for GDI interop with DXGI surfaces. Although the launcher does need some other Wine fixes due to a bug in Wine's Direct2D support.

  • Why retail marketers must get CX right the first time and how open source plays a key role

    One of the great things about technology is that it has raised all of our expectations. Once upon a time, people worried that controlling their television with a remote would make them lazy. Now, we don't even have to find the remote. We just talk to the TV — literally. We access hundreds of goods and services easily, without leaving the comfort of our chairs: we download games, order the supermarket shop, watch films and read books online. It really is a brave new world.

    But with new worlds come new challenges, and the challenge of the new, tech-driven, marketplace is to make your business stand out in a global crowd. Of all the businesses in all the world, why should your customers choose (and stick with) you?

    Lots of people will tell you that the key to gaining market share lies in improving the customer experience. And they'll be right. A combination of the need to impress and increased customer expectations have combined to make CX fundamental to gaining and retaining custom.

  • How spicy should a jalapeno be?

    Everyone has opinions and preferences, especially when it comes to food. To establish a criterion when answering "How spicy should a jalapeño be?." the Scoville Heat Scale was developed as a standard to measure spiciness. This scale allows people to communicate and share information about how spicy we like our peppers.

    Similarly, open source technology standards, such as USB, I2C, MQTT, and others, were developed to enable global compatibility. Furthermore, open source hardware platforms have enabled communities to “speak the same language” without reinventing the wheel. For example, Raspberry Pi makes it easy for people to use their hardware as a baseline and then add onto it. This has created a revolution in many industries by enabling individuals, startups, and large corporations to apply hardware and software to complex problems without having to design them from the ground up.

  • Firefox 69 dropped support for <keygen>

    With version 69, firefox removed the support for the <keygen> feature to easily deploy TLS client certificates.
    It's kind of sad how used I've become to firefox giving me less and less reasons to use it...

  • [Mozilla] Restricting third-party iframe widgets using the sandbox attribute, referrer policy and feature policy

    Adding third-party embedded widgets on a website is a common but potentially dangerous practice. Thankfully, the web platform offers a few controls that can help mitigate the risks. While this post uses the example of an embedded SurveyMonkey survey, the principles can be used for all kinds of other widgets.

    Note that this is by no means an endorsement of SurveyMonkey's proprietary service. If you are looking for a survey product, you should consider a free and open source alternative like LimeSurvey.

DM-Clone Target Added To Linux 5.4 For Efficient Remote Replication Of A Block Device

Filed under
Linux

Added to the device mapper (DM) code with the Linux 5.4 kernel is an interesting addition that benefits those wanting to carry out some interesting use-cases around remote replication of block devices.

As explained in the original patch proposal for dm-clone, "dm-clone produces a one-to-one copy of an existing, read-only device (origin) into a writable device (clone): It presents a virtual block device which makes all data appear immediately, and redirects reads and writes accordingly. The main use case of dm-clone is to clone a potentially remote, high-latency, read-only, archival-type block device into a writable, fast, primary-type device for fast, low-latency I/O. The cloned device is visible/mountable immediately and the copy of the origin device to the clone device happens in the background, in parallel with user I/O."

  • OpenShift Commons Gathering in Milan 2019 – Recap [Slides]

    On September 18th, 2019, the first OpenShift Commons Gathering Milan brought together over 300 experts to discuss container technologies, operators, the operator framework and the open source software projects that support the OpenShift ecosystem. This was the first OpenShift Commons Gathering to take place in Italy.

    The standing room only event hosted 11 talks in a whirlwind day of discussions. Of particular interest to the community was Christian Glombek’s presentation updating the status and roadmap for OKD4 and CoreOS.

    Highlights from the Gathering induled an OpenShift 4 Roadmap Update, customer stories from Amadeus, the leading travel technology company, and local stories from Poste Italiane and SIA S.p.A. In addition to the technical updates and customer talks, there was plenty of time to network during the breaks and enjoy the famous Italian coffee.

  • Powering the hybrid cloud on next-generation hardware: Red Hat Enterprise Linux on IBM System Z and LinuxONE

    For more than five years we have been driving our technology strategy around the idea that the future of enterprise IT does not reside solely in an enterprise datacenter or in the public cloud. Instead the next wave of computing is built on a blend of these technologies and infrastructure: in short, the future is hybrid. The value of hybrid clouds comes from the choice it delivers, pairing the control of the corporate datacenter alongside the scale and flexibility of public clouds. We strongly feel, however, that the most valuable hybrid clouds are those that offer not only a choice of deployment type and location, but also a choice of the underlying architecture and the capacity to run on multiple public clouds.

    [....]

    With RHEL available on Z15 and LinuxONE III, this helps pave the way for the rest of Red Hat’s hybrid cloud portfolio, including Red Hat OpenShift, to emerge on IBM enterprise platforms. We’re pleased to continue our work with IBM in bringing the world’s leading enterprise Linux platform to their next-generation systems.

KDE: New Features, Kate, Windows and KItinerary

  • This week in KDE: a metric avalanche of amazing things

    Get ready for a massive load of improvement! And it’s all pretty darn shiny too because in addition to a ton of work on apps, we polished up Plasma to be as smooth as a marble for the 5.17 beta version (numbered 5.16.90), which is now available. The final product is due to be released in about a month, and as you’ll see, KDE contributors have been hard at work making it as awesome as humanly possible! A few things have slipped until the Plasma 5.18 LTS release, but that’s okay because it means 3 more months to polish them up.

    Oh, one more thing before we begin: like Kate, Okular is now also available on the Microsoft store! This work is so important because Windows users who become accustomed to using free open source software on Windows are more easily able to switch to a fully FOSS platform, like a Linux distro running KDE Plasma.

  • [Kate] External Tools Plugin is Back

    Back in 2011, we decided to remove the External Tools plugin in Kate for the KDE 4.8 release, since it was unmaintained and we got more and more bugs that were not fixed. However, over the years, we got many requests (and complaints) to bring this plugin back to life, since it was very useful to start little helper scripts with just a shortcut, via the command line, or the menu.

    The good news is that for the KDE Applications 19.12 release, the External Tools plugin will be back! And it is much improved compared to the previous version.

  • KDE applications on Windows

    One of the new goals of KDE is to spread the use of the applications created by the KDE community. This doesn’t only include the use of them on Linux & other Unix-like operating systems, but Windows, too.

  • KItinerary Command Line Extractor

    The KItinerary data extraction engine recently got a command line interface, which can be pointed at any file KItinerary can consume (HTML, PDF, plain text, iCal, Apple Wallet passes, etc) and which then outputs JSON-LD according to the schema.org data model with the information that could be found in there. Adding this has been motivated by two separate goals: Increasing extractor robustness, and easing integration into 3rd party applications.

Building A Linux HTPC / Storage Server With The SilverStone CS381

SilverStone recently sent over their CS381 chassis that has proven to be quite a versatile micro-ATX enclosure that can accommodate up to twelve hard drives (eight of which are hot-swappable) all while coming in at just 400 x 225 x 316mm. The SilverStone CS381 could work quite well as a Linux HTPC / DIY Steam Linux gaming living room PC or SOHO file server system with its compact size while offering immense storage potential. Here's more on the SilverStone CS381 and our build with using a Ryzen 5 3400G that is playing well under Linux with an ASUS B450 motherboard. It's been a while since last taking a look at any SilverStone enclosure, but with continuing to be impressed by their high-end cases over the years, it was exciting to look at the CS381 from their Case Storage Series. The key features of this case are offering support for up to twelve HDD/SSDs, up to a microATX motherboard, and other components while occupying just 30 liters of space. The case can be positioned in either a vertical or horizontal position depending upon the environment and eight of the drives being hot-swappable primes the case for interesting storage server options.

Intel Icelake Thunderbolt Support, Stratix10 Additions & Other Material Hits Linux 5.4

The "char/misc" changes for the Linux 5.4 are as eventful as ever. Greg Kroah-Hartman sent in the char/misc changes earlier this week for the Linux 5.4 merge window that's now half-way through. The since merged material contains a lot of notable hardware support improvements. Exciting us the most is that the Intel Icelake Thunderbolt support is now squared away. Intel had most of the Icelake CPU support in good shape going back months including for the Gen11 graphics, but the Thunderbolt support was the last holdout. With Icelake, the Thunderbolt controller has moved onto the CPU package itself sans the power deliver infrastructure. These changes yielded additional work to get Icelake Thunderbolt support going under Linux, but it's finally there for Linux 5.4 with Icelake laptops beginning to hit retail channels. Read more

Python Programming Leftovers

  • Cogito, Ergo Sumana: Futureproofing Your Python Tools

    The people who maintain Python and key Python platforms want to help you protect the code you write and depend on. [...] Publishing that package is a great way of making it so other people can run and deploy it, even within other parts of your organization. But -- who actually has the keys to the castle? Who can upload a new version, or delete a version that has a problem? You should probably make sure multiple people have either "owner" or "maintainer" privileges on the project on PyPI. And you should review your project security history display, which lists sensitive events (such as "file removed from release version 1.0.1") in your PyPI user account and your PyPI project. We just added this display, so you can look at things that have happened in your user account or project, and check for signs someone's stolen your credentials.

Geary 3.34 Debuts with Deeper GNOME Contacts Integration, Other Changes

The Geary email client has issued a brand new release, and in this post I tell you a bit about it. Geary 3.34.0 — you may recall that Geary switched to following GNOME numbering last year — is the latest update to this web-mail friendly mail tool, and there’s healthy dose of improvement on offer, as noted in the release notes. Among them is deeper integration with GNOME Contacts. Geary’s in-app contacts pop-over now supports adding and editing contacts stored in the GNOME Contacts app, and is able to auto-complete email addresses based on data from contacts too. Serial typo-makers like me will appreciate the spell checker now covering the mail composer’s subject line; while the addition of support for Outlook-specific email attachments (TNEF) will please those who regularly run in to issues on that front. Other changes in Geary 3.34.0 include “a substantial number” of server compatibility improvements, background syncing tweaks, and other bug fixes. Read more
