Quick Roundup

Comparing the similarities and differences between inner source and open source

Filed under
OSS

Open source software (OSS) has been around since the 1990s and has thrived, quickly growing to become mainstream. It is now more well understood around the world than it has ever been before. Some refer to it as FOSS to highlight the Freedom part of open source (Free and Open Source Software). And in 2014, at OSCON, the term "inner source" was debuted, and people started talking about how to use the principles of open source, but inside of a company. It raised several questions for those unfamiliar with the term, which I hope to answer with this article. For example, what is similar about the two, what is different, the company roles involved in the two, is inner source taking the energy away from open source, etc. These are all fair questions, and as my organization practices both and is involved in both movements, I want to take some time to share insight with this audience as a developer, as a company, and as an open source enthusiast.

4 questions about AI ethics and how open source can help

Filed under
OSS

As a high school student, I've become very interested in artificial intelligence (AI), which is emerging as one of the most impactful innovations of recent times. This past summer, I was selected for the AI4ALL program, where we learned how to develop AI systems using Python.

For my final project, I created an object-detection program and integrated it with a virtual drone simulation. Throughout the project, I was able to use open source frameworks, including TensorFlow, Keras, Scikit-learn, and PyTorch, to aid in developing the object-detection machine learning (ML) algorithm process.

MuditaOS: A Beautiful and Minimal Open Source Mobile Operating System

Filed under
OS
OSS

MuditaOS is a beautiful, minimal open-source operating system for mobile phones. Unlike other mobile phone operating systems, however, the developers behind MuditaOS are not interested in smartphones. Instead, they aim to take us to the era before the smartphone craze that has lead to distrust for big tech companies, but with a far cooler style.

Developing this mobile operating system has admittedly been a challenge to the team and they are excited to have come up with a beautifully designed E Ink OS, which they have open-sourced to meet the modern user’s desire for transparency without compromising quality.

When the company developed and open-source the operating system, they announced that open-sourcing the OS goes along the lines of their “You’re happy – I’m Happy” philosophy and this makes even more sense when you understand that Mudita is from the Sanskrit word “Mudit” which translates to ‘Happy‘.

  • Systemd 247 Released With Experimental Out-of-Memory Daemon, New Credentials Capability - Phoronix

    Systemd 247 is out today as the latest major version of this Linux init system. Like most systemd releases, systemd 247 is very heavy on new features. 

    Systemd 247 most notably introduces the still-experimental systemd-oomd as the out-of-memory daemon with that Linux OOMD code originally developed by Facebook and later adopted for desktop use-cases. Once stabilized, the goal of systemd-oomd is for improving the behavior when the Linux system is low on memory / under memory pressure. 

    Beyond systemd-oomd, systemd 247 now defaults to using Btrfs with systemd-homed and other enhancements as outlined below.

    OpenZFS 2.0-RC7 is lighter than some of the past release candidates so it looks like work may be winding down. OpenZFS 2.0 is a big release with Zstd compression, mainlined FreeBSD support, various performance improvements, sequential resilvering, persistent L2ARC support, and many other changes.

    AMD on Wednesday sent out more AMDGPU kernel driver updates for Navy Flounder and Dimgrey Cavefish. Navy and Dimgrey are for unreleased AMD Radeon products that appear to be for additional RDNA 2 / Radeon RX 6000 series parts. Nothing too notable with the latest batch of updates, just more enablement churn and more device IDs added in.

Arcan 0.6 – ‘M’ – Start Networking

Filed under
Graphics/Benchmarks

This time around, the changes are big enough across the board that the sub-projects will get individual posts instead of being clumped together, and that will become a recurring theme as the progress cadence becomes less and less interlocked.

We also have a sister blog at www.divergent-desktop.org that will slowly cover higher level design philosophy, rants and reasoning behind some of what is being done here. A few observant ones have pieced together the puzzle — but most have not.

This release is a thematic shift from low level graphics plumbing to the network transparency related code. We will still make and accept patches, changes and features to the lower video layers, of course — ‘Moby Blit’ is still out there — but focus will be elsewhere. Hopefully this will be one of the last time these massive releases make sense, and we can tick on a (bi-)monthly basis for a while.

  • Embedded Linux for Teams | Ubuntu

    Developer-friendly embedded Linux should just deliver apps to devices. Satellite companies don’t build their own rockets. They focus on building satellites and lease a rocket to deliver it as a payload. Many developer teams also have to “build the rocket” to deliver embedded applications.

    Developers would be more successful, if Linux vendors made it their job to provide and maintain the scaffold that teams need to deliver embedded apps. In such a world, teams would focus on creating apps.

    The resulting app-centric development cycle could boil down to booting, building and deploying. Building on top of vendor-provided scaffolds, developers would create a bootable image for their target boards. Teams would then develop apps. After testing, they will build a system image that delivers all these apps. Then burn, deploy, done.

  • Run Pi-hole as a container with Podman on openSUSE - SUSE Communities

    There is arguably no better way to protect devices on your local network from unwanted content than Pi-hole. Add a machine running Pi-hole to your network, and it will quietly scrub all incoming traffic from pesky stuff like ads and trackers in the background. As the name suggests, Pi-hole was initially designed to run on a Raspberry Pi. But if you already have a machine running openSUSE on your network, you can deploy a Pi-hole container on it instead. And to make things a bit more interesting, you can use Podman instead of Docker for that.

    Installing Podman on openSUSE 15.2 is a matter of running the sudo zypper install podman command. A Pi-hole container needs the 80 and 53 ports, so make sure that these ports are available on your machine.

  • Best forensic and pentesting Linux distros of 2020

    20.04 LTS and uses the Xfce desktop, and is available as a single ISO only for 64-bit machines. In addition to the regular boot options, the distro’s boot menu also offers the option to boot into a forensics mode where it doesn’t mount the disks on the computer.

    BackBox includes some of the most common security and analysis tools. The project aims for a wide spread of goals, ranging from network analysis, stress tests, sniffing, vulnerability assessment, computer forensic analysis, exploitation, privilege escalation, and more.

    All the pentesting tools are neatly organized in the Auditing menu under relevant categories. These are broadly divided into three sections. The first has tools to help you gather information about the environment, assess vulnerabilities of web tools, and more. The second has tools to help you reverse-engineer programs and social-engineer people. The third has tools for all kinds of analysis.

    BackBox has further customized its application menu to display tooltips with a brief description of each bundled tool, which will be really helpful for new users who aren’t familiar with the tools.

    As an added bonus, the distro also ships with Tor and a script that will route all Internet bound traffic from the distro via the Tor network.

  • Disappointing: Netflix Decides To Settle With Chooseco LLC Over 'Bandersnatch' Lawsuit

    Well, it's been quite a stupid and frustrating run in the trademark lawsuit between Netflix and Chooseco LLC, the folks behind Choose Your Own Adventure books from our youth. At issue was the Black Mirror production Bandersnatch, in which the viewer takes part in an interactive film where they help decide the outcome. The main character is creating a book he refers to as a "choose your own adventure" book. Chooseco also complained that the dark nature of the film would make the public think less of CYOA books as a result. Netflix fought back hard, arguing for a dismissal on First Amendment grounds, since the film is a work of art and the limited use or reference to CYOA books was an important, though small, part of that art. The court decided that any such argument was better made at trial and allowed this madness to proceed, leading Netflix to petition for the cancellation of Chooseco's trademark entirely. This story all seemed to be speeding towards an appropriately impactful conclusion.

  • TPM circumvention and website blocking orders: An EU perspective

    Website blocking orders in IP cases (mostly, though not solely, in relation to copyright-infringing websites) are routinely granted in several jurisdictions, whether in Europe or third countries. The availability of such relief has been established in case law, administrative frameworks and academic studies alike.

    The Court of Justice of the European Union ('CJEU') expressly acknowledged the compatibility of such a remedy with EU law in its 2014 decision in UPC Telekabel. Also the European Court of Human Rights recently found that, although it is necessary that this particular remedy is available within a balanced and carefully drafted legislative framework which contains a robust and articulated set of safeguards against abuse, website blocking orders are not per se contrary to the provision in Article 10 ECHR.

    Over time, courts and other authorities (including administrative authorities in certain EU Member States) have dealt with applications which have: been based on different legal grounds; been aimed at protecting different types of rights; and resulted in different types of orders against internet service providers ('ISPs').

    An interesting recent development concerns website blocking orders in relation to websites that market and sell devices and software aimed at circumventing technological protection measures (‘TPMs’). TPMs offer rights holders an ancillary right of protection and are deployed to protect against infringement of copyright in works that subsist in multimedia content such as video games. TPMs are a cornerstone in copyright protection in the digital age where large-scale copying and dissemination of copyright-protected content is so prevalent.

    [...]

    In light of the foregoing, copyright owners appear entitled to seek injunctions against intermediaries to also block access to websites dealing with TPM-circumventing devices. The legal basis for that can also be, subject to satisfying all the other requirements under EU and national law, the domestic provision implementing Article 8(3) of the InfoSoc Directive.

    All in all, it appears likely that we will see more blocking orders in the future, including orders – issued by courts and competent authorities around Europe – targeting websites that provide TPM-circumventing devices. This is an unsurprising and natural evolution of website blocking jurisprudence. It also serves to show the very flexibility of this type of remedy and, matched inter alia with the loose notion of ‘intermediary’, its inherently broad availability.

Mozilla/Firefox: CRLite, Firefox 83 and TenFourFox

Filed under
Moz/FF
  • Querying CRLite for WebPKI Revocations • Insufficient.Coffee

    Firefox Nightly is now using CRLite to determine if websites’ certificates are revoked — e.g., if the Certificate Authority published that web browsers shouldn’t trust that website certificate. Telemetry shows that querying the local CRLite dataset is much faster than making a network connection for OCSP, which makes intuitive sense. It also avoids sending the website’s certificate information in cleartext over the network to check the revocation status: solving one of the remaining cleartext browsing data leakages in Firefox.

    Mozilla is currently publishing CRLite data to Remote Settings four times per day, keeping a very fresh set of revocation information for the public Web. I’ve provided some direct details on how to get at that data from the CRLite FAQ, and I want to introduce one of my command-line tools I’ve used to analyze and play with the dataset: moz_crlite_query. I’ll introduce crlite_status in a later post.

  • Firefox 83 Introduces HTTPS-Only Mode

    According to Mozilla, “the web contains millions of legacy HTTP links that point to insecure versions of websites. When you click on such a link, browsers traditionally connect to the website using the insecure HTTP protocol.”

    With HTTPS-Only Mode enabled, Firefox will attempt to establish HTTPS connections to every website and will ask for permission before connecting to a site that doesn’t support secure connections. Even if you click on an HTTP link or manually enter an HTTP address, Firefox will use HTTPS instead.

  • TenFourFox Development: TenFourFox FPR30b1 available

    TenFourFox Feature Parity Release 30 beta 1 is now available (downloads, hashes, release notes). I managed to make some good progress on backporting later improvements to the network and URL handling code, so there are no UI-facing features in this release, but the browser should use a bit less memory and run a little quicker especially on pages that reference a lot of resources (which, admittedly, is a lot of sites these days). There is also a minor update to the host database for basic adblock. Assuming all goes well, this release will come out parallel with Firefox 84 on or around December 15. I'll probably do an SPR-only build for the release immediately following to give myself a break; this will contain just needed security fixes, and there will most likely not be a beta.

Music Production on Guix System

Filed under
OS
GNU

The working title “Ode to One Two Oh” was an obvious choice, being a quasi-palindrome, and its five syllables suggested a time signature of 5/4. Where to from here?

As I stared at my Emacs session with a Guile REPL (read, eval, print, loop) buffer I tried to recall what the letters “REPL” stand for. Clearly, in my case the “P” was for “Procrastination”, but what about the others? I had stumbled upon the chorus: a description of the Guix development process. Contribute as others before us have shared their contributions (Reciprocation), review patches and discuss (Evaluation), hack on something else (Procrastination), and repeat (Loop).

The words suggested a simple descending melody, which would need to be elevated by a somewhat less simple chord progression. After trying out a few harmonies on the Grand Stick I remembered how terrible my memory was and decided that I would need to scatter the harmonies onto a canvas, listen to the whole progression, and adjust the lines as needed — all without having to build up muscle memory for harmonies and progressions I may very well end up discarding in the process.

This is where my composition workflow probably deviates from most other people. Many would use a MIDI sequencer for that kind of approach, whereas I decided to hone in on the exact harmonies with an unlikely tool: the unparalleled music engraving application Lilypond. Lilypond sports a versatile language that covers primitive note input, the means of combining them to larger phrases and musical ideas, and the means of abstraction — it allows for musical ideas to be named and recombined in different shapes. For everything the language doesn’t account for with specialized syntax I can simply switch to Guile Scheme. No other notation software is as flexible and malleable as Lilypond. I let it generate both sheet music and a MIDI file — the sheet music is displayed in a PDF viewer in Emacs and the MIDI file sent to fluidsynth (because I trust my ears over my eyes).

The Few, the Tired, the Open Source Coders

Filed under
Development
OSS

Sometimes open source coders simply walk away: Let someone else deal with this crap. Studies suggest that about 9.5 percent of all open source code is abandoned, and a quarter is probably close to being so. This can be dangerous: If code isn't regularly updated, it risks causing havoc if someone later relies on it. Worse, abandoned code can be hijacked for ill use. Two years ago, the pseudonymous coder right9ctrl took over a piece of open source code that was used by bitcoin firms—and then rewrote it to try to steal cryptocurrency.

No one's quite sure what to do about open source burnout, but some think finding money for the coders might help. Programmer Ashley Williams is a member of the team creating the open source language Rust, and they're trying to set up a foundation to support core contributors, or get firms to keep contributors on staff. (Some of the largest open source projects thrive in precisely this fashion; firms like Facebook or Google pay some employees to work full-time on open source code.) Eghbal thinks subscriptions could offer new ways to pay for the work. Others worry that injecting pay can deform how and why the work is done in the first place.

But we need to rethink the very idea of what crowdsourcing is capable of—and understand that it is perhaps more limited than promised. The open source revolution has been carried on the backs of some very weary people.

  • Orchestrate event-driven, distributed services with Serverless Workflow and Kubernetes - Red Hat Developer

    Serverless workflows have gained renewed interest and usefulness with the rise of serverless architectures. Once seen as centralized and monolithic, they now play a key role in cloud-based event and service orchestration. Until recently, there was no vendor-neutral way to describe service orchestration, so developers were dependent on vendors and vendor implementations. We realized that we needed a common, standards-based language for describing serverless workflows.

    In this article, we introduce the Serverless Workflow specification, now in its 0.5 version release. Our goal with this project is to empower anyone to develop serverless workflow libraries, tooling, and infrastructure for modeling workflows across different cloud platforms.

Qt Desktop Days Outline/Talks

Development
  • Qt Desktop Days – Day 1 - KDAB

    If you missed Qt Desktop Days, you might be wondering what you missed. No need to worry! We’re going to give you a day-by-day summary of some of the cool things that were discussed, demoed, and explained. (We’re uploading all of the videos to our YouTube channel, but we’ll provide the direct links to each talk here as well.)

  • Qt Desktop Days - Day 2 - KDAB

    The first session on day 2 was from Nyall Dawson who works for North Road but who is also a significant contributor to QGIS, the largest open-source GIS program in the world. Nyall explains why Qt is an awesome fit for this massive desktop application, and why he believes that Qt is partly responsible for its longevity and success. To understand exactly why QGIS is such a beast (over 1.5 million lines of code and over 500 code contributors), he explains what a GIS system is expected to do, like consuming and creating spatial data, creating high-impact and professionally designed maps, and doing geographical analysis – all with multiple coordinates, projects, and extreme accuracy.

    Bluescape is a company that creates collaborative, multi-screen, multi-touch whiteboards – some pretty “Minority Report” type of stuff. Bluescape’s Romain Pokrzywka joined us to talk about how to really wrangle touch and pen input, and how to develop applications that need to live equally well across mouse and keyboard desktop, touch screen laptops, tablets, and mobile devices.

    Romain talks about the specifics of Qt multi-touch and pen support in both C++ and QML, gives us some of his hard-learned lessons about how to best develop applications that merge these features, and shares his tips and tricks on what works best (like what to do with those non-conformist mouse wheels). He also discusses what’s coming down the pike for Qt 6 when it comes to input API changes, including some long overdue changes.

  • Qt Desktop Days - Day 3 - KDAB

    If you’re building a desktop application today, should you consider building the UI with Qt Quick? That’s the question that KDABian Shantanu Tushar answers in this session. He walks us through the pros and cons of Qt Widgets versus Qt Quick, and explains that although there are still plenty of good reasons to use widgets, there are a lot of advantages that you’re missing if you dismiss a QML-based desktop app out-of-hand.

    But desktop apps aren’t the same as mobile ones, and having implemented many desktop applications in QML, Shantanu knows what works and what doesn’t. He explains how desktop apps are often more complex than mobile, and how he manages to tame QML complexity with imports, assets, and namespaces. He also covers issues that desktop developers need to handle such as screen layout trade-offs and styling to match native controls. Shantanu also gives us real-life examples of why and how to mix designer screens and implementation screens in the same application. If you’re thinking about going down the QML route with your app, you should really watch this talk before you begin.

  • Qt Desktop Days – Day 4 - KDAB

    If you need to play the widest variety of audio, video, or streaming formats on the planet, you probably know about VLC (the “cone player”). But did you know that VLC uses Qt? They didn’t always. Hear the history of this interesting project from Jean-Baptiste Kempf, one of the lead developers on VLC, a project started by rebellious French university students over two decades ago that is still going strong today.

    We learn from Jean-Baptiste some interesting platform constraints of the VLC project (like unbelievably, they still support OS/2!), and how their abstraction architecture has been able to grow and thrive without software bloat despite years of changing software, multiple new platforms, and loads of new features. We also learn what factors drove the switch from wxWidgets to Qt and what the team did to keep their high-performance video codecs working smoothly in their upcoming port from Qt4 to Qt5. If you’re tackling your own open-source project, the dynamic success of VLC as delivered by Jean-Baptiste might be just the inspiration you need.

  • Systemd 247 Released With Experimental Out-of-Memory Daemon, New Credentials Capability - Phoronix

    Systemd 247 is out today as the latest major version of this Linux init system. Like most systemd releases, systemd 247 is very heavy on new features.  Systemd 247 most notably introduces the still-experimental systemd-oomd as the out-of-memory daemon with that Linux OOMD code originally developed by Facebook and later adopted for desktop use-cases. Once stabilized, the goal of systemd-oomd is for improving the behavior when the Linux system is low on memory / under memory pressure.  Beyond systemd-oomd, systemd 247 now defaults to using Btrfs with systemd-homed and other enhancements as outlined below.

  • OpenZFS 2.0-RC7 Brings Better ABI Handling, Reduced Latency For Non-Interactive I/O - Phoronix

    OpenZFS 2.0 is getting quite close to release but isn't over the finish line yet and this week brings the seventh release candidate.  OpenZFS 2.0-RC7 is lighter than some of the past release candidates so it looks like work may be winding down. OpenZFS 2.0 is a big release with Zstd compression, mainlined FreeBSD support, various performance improvements, sequential resilvering, persistent L2ARC support, and many other changes.

  • AMD Stages More Driver Updates For New GPUs With Linux 5.11 - Phoronix

    While the Radeon RX 6800 series is now shipping that was developed under the Sienna Cichlid codename, there are other fishy codenames remaining and are seeing more work for the Linux 5.11 kernel that will officially open development in December and then likely reaching stable in February.  AMD on Wednesday sent out more AMDGPU kernel driver updates for Navy Flounder and Dimgrey Cavefish. Navy and Dimgrey are for unreleased AMD Radeon products that appear to be for additional RDNA 2 / Radeon RX 6000 series parts. Nothing too notable with the latest batch of updates, just more enablement churn and more device IDs added in.
