Run a Linux Terminal on Cheap E-Ink Displays

Filed under
Linux
Hardware

If you haven’t kept up with the world of e-ink displays, here’s some good news: they are pretty cheap now. For as little as $15 you can get a small e-ink display that has good enough performance and contrast to actually do something useful. There’s only one problem: figuring out how to drive them in your project.

Tired of seeing nothing but wiring diagrams and sample code when it came to actually putting these e-ink modules to use, [Jouko Strömmer] decided to try his hand at creating a turn-key application for these gorgeous little displays. The result is PaperTTY, a Python program that allows the user to open up a fully functional Linux virtual terminal on an e-ink display.

Linux
  • EXT4 & XFS File-System Updates Submitted For Linux 4.19

    The pull requests updating the XFS and EXT4 file-system driver code have been sent in for the recently started Linux 4.19 kernel merge window.

    On the EXT4 file-system front, the documentation on the project's Wiki has been converted into documentation files within the kernel tree. Additionally, there is now 64-bit timestamp support for EXT4's superblock fields, a Spectre gadget fix, hardening against maliciously corrupted file-systems, and various other bug fixes and code improvements.

  • Linux 4.19 Will Fend Off Stack Attacks With STACKLEAK Plugin

    As expected, Linux 4.19 is getting STACKLEAK as a GCC plug-in for the Linux kernel that will fend off various form of stack attacks.

    STACKLEAK is ported from the last open-source code of the GrSecurity/PaX modified kernel and wipes out the kernel stack before returning from system calls.

  • Open Source cleaning up at the Oscars

    Over the last 25 years, software, and particularly open source software (OSS), has played an increasingly important role in the most successful movies of our time.

    Now this contribution is set to grow, boosted by the introduction on Friday, of the Academy Software Foundation (ASWF), a joint venture of the Academy of Motion Picture Arts and Sciences - the organisation behind the annual Oscar awards and the Linux Foundation.

    This follows a recently concluded two-year investigation by the Academy which found that more than 80% of the motion picture industry uses OSS, particularly for animation and visual effects.

  • AMPAS, Linux Foundation Launch Academy Software Foundation

    “Developers and engineers across the industry are constantly working to find new ways to bring images to life, and open source enables them to start with a solid foundation while focusing on solving unique, creative challenges rather than reinventing the wheel,” said Rob Bredow, SVP, Executive Creative Director and Head of Industrial Light & Magic and Member of the Academy’s Science and Technology Council, Open Source Investigation Committee. “We are very excited to launch the Academy Software Foundation and provide a home for open source developers to collaborate, regardless of where they work, and share best practices which we believe will drive innovation across the industry.”

  • The Academy of Motion Picture Arts and Sciences and The Linux Foundation Launched the Academy Software Foundation, Linux 4.18 and GNU Linux-libre 4.18-gnu Kernels Are Out, DXVK 0.65 Released and Canonical Live Patch Update

    The Academy of Motion Picture Arts and Sciences and The Linux Foundation launched the Academy Software Foundation late last week. The ASF's mission is to "increase the quality and quantity of contributions to the content creation industry's open source software base; to provide a neutral forum to coordinate cross-project efforts; to provide a common build and test infrastructure; and to provide individuals and organizations a clear path to participation in advancing our open source ecosystem".

  • Red Hat’s Adam Clater Provides Recommendations for DevSecOps Practices in Government

    Adam Clater, chief architect for Red Hat’s North American public sector, has said there is a need for federal agencies to accept the integration of security in software development processes as a cultural change, MeriTalk reported Monday.

    Clater believes it is important that agency managers grasp the need to standardize their way of creating software systems to add stability and security in development and operations or DevOps practices, leading to a new concept called DevSecOps.

    The Red Hat official told agency managers to begin with undertaking easy and uncomplicated steps to determine how they should adapt to DevSecOps.

  • Could your team be managing itself?

    I was engaged recently in a passionate conversation ignited by a simple comment: "A team has to be managed." The comment made me think I wasn't on the same page as my interlocutor.

    I was discussing the importance of designing organizational roles that won't become bottlenecks (roles that won't prevent the organization from delivering efficiently or to adapting quickly to changes). In classic organization design, we tend to think that designing boxes on an organizational chart and putting great people in charge will solve all our problems. That approach could work in static environments, where what you have to deliver is defined once and for all.

  • Improving rsync performance with GlusterFS

    Rsync is a particularly tough workload for GlusterFS because with its defaults, it exercises some of the worst case operations for GlusterFS. GlusterFS is the core of Red Hat Gluster’s scale-out storage solution. Gluster is an open, software-defined storage (SDS) platform that is designed to scale out to handle data intensive tasks across many servers in physical, virtual, or cloud deployments. Since GlusterFS is a POSIX compatible distributed file system, getting the best performance from rsync requires some tuning/tweaking on both sides.

    In this post, I will go through some of the pain points and the different tunables for working around the pain points. Getting rsync to run as fast on GlusterFS as it would on a local file system is not really feasible given its architecture, but below I describe how to get as close as possible.

FreeBSD 12.0 Alpha Hits The Web

Filed under
BSD

The first alpha release of FreeBSD 12.0 was quietly uploaded a few days ago to the project's download servers as the first step to shipping this next major update to the FreeBSD operating system.

FreeBSD 12.0-ALPHA1 was successfully made back on 10 August as what begins the project's "code slush" period whereby new commits can continue being merged for 12.0 but they shouldn't be introducing new features. The actual code freeze is what's beginning later this month followed by the code branching and then the beta releases start towards the end of September.

    The Go networking library includes the http.ServeMux structure type, which supports HTTP request multiplexing (routing): A web server routes an HTTP request for a hosted resource, with a URI such as /sales4today, to a code handler; the handler performs the appropriate logic before sending an HTTP response, typically an HTML page.

  • Blender 2.8 Alpha 2 Just Released, but Full Release Pushed to Early 2019

    The free and open-source Blender 3D modeling software, a popular alternative to more expensive suites like Maya LT and 3DS Max, is facing a bit of a delay in their release schedule for Blender 2.80 – however, the developers intend to release it by early next year 2019.

    The devs had hoped to have a feature complete beta ready this August 2018, but that doesn’t look like a possibility either – the team spent most of their time “improving” the currently existing features, and eliminating current bugs within the software. However, a Blender 2.80 Alpha 2 was released just today.

  • Browsh – A Modern Text Browser That Play Videos and Everything

    Browsh is an open source, simple and modern text-based browser that renders in TTY terminal environments. It is made up of a minimal Golang CLI front-end and a browser web-extension (headless Firefox) which actually offers most of the functionality to create a purely text-based version of web pages and web apps.

    This browser renders anything that a modern browser can; HTML5, CSS3, JS, video as well as WebGL. It is importantly a bandwidth-saver, designed to run on a remote server and accessed via SSH/Mosh or the in-browser HTML service so as to notably reduce bandwidth.

    Video editing on Linux platform just got a whole lot easier, as Blackmagic Design just released their long-awaited DaVinci Resolve 15 software update – a free to use professional-grade video editing, visual effects, motion graphics, and audio post-production software suite.

  • Professional Video Editor DaVinci Resolve 15 Stable Released

    DaVinci Resolve 15 stable has been released for Linux, Windows, and macOS. The new release brings native audio support on Linux and a long list of new features and improvements.

    DaVinci Resolve is a professional video and effects editor. The tool, which can be used for editing, color correction, audio post production and visual effects, has two versions: free to use and paid (DaVinci Resolve Studio).

    The free to use version does not support h26x so you'll need to transcode any such clips before using them in DaVinci resolve. DaVinci Resolve 15 Studio costs $299 and it includes multi-user collaboration features along with 3D tools, dozens of Resolve FX and more.

    In the context of Google Summer of Code 2018, my mentor (Martin Schanzenbach) and I have worked on creating and extending the REST API of GNUnet. Currently, we mirrored the functionality of following commands:

    gnunet-identity
    gnunet-namestore

    gnunet-peerinfo

    Additionally, we developed a website with the Javascript framework Angular 6 and the design framework iotaCSS to use the new REST API. The REST API of GNUnet is now documented with Sphinx.

  • GSoC 2018 report: Cuirass Web interface

    For the last three months I have been working with the Guix team as a Google Summer of Code intern. The title of my project is "GNU Guix (Cuirass): Adding a web interface similar to the Hydra web interface".

    Cuirass is a continuous integration system which monitors the Guix git repository, schedules builds of Guix packages, and presents the build status of all Guix packages. Before my project, Cuirass did not have a web interface. The goal of the project was to implement an interface for Cuirass which would allow a user to view the overall build progress, details about evaluations, build failures, etc. The web interface of Hydra is a good example of such a tool.

    In this post, I present a final report on the project. The Cuirass repository with the changes made during the project is located at http://git.savannah.gnu.org/cgit/guix/guix-cuirass.git. A working instance of the implemented interface is available at https://berlin.guixsd.org/. You can find more examples and demonstrations of the achieved results below.

  • [Rust] Diagnosing A Weak Memory Ordering Bug

    For the first time in my life I tracked a real bug's root cause to incorrect usage of weak memory orderings. Until now weak memory bugs were something I knew about but had subconciously felt were only relevant to wizards coding on big iron, partly because until recently I've spent most of my career using desktop x86 machines.

    Under heavy load a Pernosco service would assert in Rust's std::thread::Thread::unpark() with the error "inconsistent state in unpark". Inspecting the code led to the disturbing conclusion that the only way to trigger this assertion was memory corruption; the value of self.inner.state should always be between 0 and 2 inclusive, and if so then we shouldn't be able to reach the panic. The problem was nondeterministic but I was able to extract a test workload that reproduced the bug every few minutes. I tried recording it in rr chaos mode but was unable to reproduce it there (which is not surprising in hindsight since rr imposes sequential consistency).

  • IEEE Survey Ranks Programming Languages

    It's been said that programming languages are akin to religion. Engineers and developers will go out of their way to defend the use of their favorite language. (Perhaps it's more the pain of learning a new language that keeps us using the old). Surely you've seen many surveys on programming language preferences. As with all surveys, the results depend on who was asked.

  • Programming Languages May Finally Be Reaching a Status Quo

    The analyst firm RedMonk has tracked programmers' interest in various programming languages since 2011. During that time, Swift and Kotlin grew faster than any other language the firm tracked, including Google's Go and Mozilla's Rust. Earlier this year Swift, which Apple released in 2014, managed to tie with Apple's much more established Objective-C language for tenth place in RedMonk's rankings.

  • Machine learning algorithms can identify anonymous programmers

    Rachel Greenstadt, associate professor of computer science at Drexel University, and Aylin Caliskan, an assistant professor at George Washington University, have found that code can be a form of stylistic expression, a bit like writing, reported Wired.

    As such, the researchers developed a machine learning algorithm to recognise the coding structure used by individual programmers based on samples of their work and spot their traits in compiled binaries or raw source code.

5 open source strategy and simulation games for Linux

Filed under
Linux
OSS
Gaming

Gaming has traditionally been one of Linux's weak points. That has changed somewhat in recent years thanks to Steam, GOG, and other efforts to bring commercial games to multiple operating systems, but those games are often not open source. Sure, the games can be played on an open source operating system, but that is not good enough for an open source purist.

So, can someone who only uses free and open source software find games that are polished enough to present a solid gaming experience without compromising their open source ideals? Absolutely. While open source games are unlikely ever to rival some of the AAA commercial games developed with massive budgets, there are plenty of open source games, in many genres, that are fun to play and can be installed from the repositories of most major Linux distributions. Even if a particular game is not packaged for a particular distribution, it is usually easy to download the game from the project's website to install and play it.

  • Virtlyst 1.2.0 released

    Virtlyst – a Web Interface to manage virtual machines build with Cutelyst/Qt/C++ got a new release.

    This new release includes a bunch of bug fixes, most importantly probably being the ability to warn user before doing important actions to help avoid doing mistakes.

    Most commits came from new contributor René Linder who is also working on a Bootstrap 4 theme and Lukas Steiner created a dockerfile for it. This is especially cool because Virtlyst repository now has 4 authors while Cutelyst which is way older has only 6.

  • Blender 2.8 Planning Update

    At this point we will not have a feature complete Beta release ready in August as we had hoped. Instead, we invested most of our time improving the features that were already there and catching up with the bug tracker. This includes making the viewport and EEVEE work on more graphics cards and platforms.

  • Dropbox will only Support the Ext4 File System In Linux in November

    Dropbox has announced that starting on November 7th 2018, only the ext4 file system will be supported in Linux for synchronizing folders in the Dropbox desktop app. Those Linux users who have synch on other file systems such as XFS, ext2, ext3, ZFS, and many others will no longer have working Dropbox synchronization after this date.

    This news came out after Linux dropbox users began seeing notifications stating "Dropbox Will Stop Syncing Ext4 File Systems in November." You can see an example of this alert in Swedish below.

  • Dropbox scares users by shrinking synching options

    Dropbox has quietly announced it will soon stop synching files that reside on drives tended by some filesystems.

    The sync ‘n’ share service’s desktop client has recently produced warnings that the software will stop syncing in November 2018.

    Those warnings were sufficiently ambiguous that Dropbox took to its support forums to explain exactly what’s going on, namely that as of November 7th, 2018, “we’re ending support for Dropbox syncing to drives with certain uncommon file systems.”

Red Hat Leftovers

  • Red Hat Advances Container Storage
    Red Hat has moved to make storage a standard element of a container platform with the release of version 3.1 of Red Hat OpenShift Container Storage (OCS), previously known as Red Hat Container Native Storage. Irshad Raihan, senior manager for product marketing for Red Hat Storage, says Red Hat decided to rebrand its container storage offering to better reflect its tight integration with the Red Hat OpenShift platform. In addition, the term “container native” continues to lose relevance given all the different flavors of container storage that now exist, adds Raihan. The latest version of the container storage software from Red Hat adds arbiter volume support to enable high availability with efficient storage utilization and better performance, enhanced storage monitoring and configuration via the Red Hat implementation of the Prometheus container monitoring framework, and block-backed persistent volumes (PVs) that can be applied to both general application workloads and Red Hat OpenShift Container Platform (OCP) infrastructure workloads. Support for PVs is especially critical because to in the case of Red Hat OCS organizations can deploy more than 1,000 PVs per cluster, which helps to reduce cluster sprawl within the IT environment, says Raihan.

    Most open source communities don’t have a lot of formal roles. There are certainly people who help with sysadmin tasks, testing, writing documentation, and translating or developing code. But people in open source communities typically move among different roles, often fulfilling several at once. In contrast, team members at most traditional companies have defined roles, working on documentation, support, QA, and in other areas. Why do open source communities take a shared-role approach, and more importantly, how does this way of collaborating affect products and customers? Nextcloud has adopted this community-style practice of mixing roles, and we see large benefits for our customers and our users.
  • FOSS Project Spotlight: SIT (Serverless Information Tracker)
    In the past decade or so, we've learned to equate the ability to collaborate with the need to be online. The advent of SaaS clearly marked the departure from a decentralized collaboration model to a heavily centralized one. While on the surface this is a very convenient delivery model, it simply doesn't fit a number of scenarios well. As somebody once said, "you can't FTP to Mars", but we don't need to go as far. There are plenty of use cases here on Earth that are less than perfectly suited for this "online world". Lower power chips and sensors, vessel/offshore collaboration, disaster recovery, remote areas, sporadically reshaping groups—all these make use of central online services a challenge. Another challenge with centralization is somewhat less thought of—building software that can handle a lot of concurrent users and that stores and processes a lot of information and never goes down is challenging and expensive, and we, as consumers, pay dearly for that effort. And not least important, software in the cloud removes our ability to adapt it perfectly for use cases beyond its owner's vision, scope and profitability considerations. Convenience isn't free, and this goes way beyond the price tag.
