  • L1 Terminal Fault - The Latest Speculative Execution Side Channel Attack

    Details are still light but a new vulnerability is coming out called the L1 Terminal Fault. It's been described as a "train-wreck" and is another big deal in the security space as the latest speculative side-channel attack vector.

    The CVEs are CVE-2018-3615, CVE-2018-3620, and CVE-2018-3646 but as of writing they have not been made public yet. I just noticed the code hitting the mainline Linux kernel to this "L1TF - L1 Terminal Fault" vulnerability.

  • Ubuntu updates for L1 Terminal Fault vulnerabilities

    Today Intel announced a new side channel vulnerability known as L1 Terminal Fault. Raoul Strackx, Jo Van Bulck, Marina Minkin, Ofir Weisse, Daniel Genkin, Baris Kasikci, Frank Piessens, Mark Silberstein, Thomas F. Wenisch, Yuval Yarom, and researchers from Intel discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that’s executing on the CPU core. Processors from other vendors are not known to be affected by L1TF.

  • Dropbox plans to drop encrypted Linux filesystems in November

    Linux users are calling on Dropbox to reverse a decision to trim its filesystem support to unencrypted EXT4 only.

    The company's supported file system list, here, is missing some formats – including various encrypted Linux filesystems.

    Until that list was revised, Dropbox said it supported NTFS, HFS, EXT4, and APFS on Linux; as the new requirements makes clear, Linux users will only be able to run unencrypted EXT4.

  • Why critics who bash Musk's open source Tesla security project are wrong

    While some have characterized this move as self-serving, a way to make Tesla "look good from a marketing standpoint," this completely misses the point. While some have used open source as a vapid marketing gesture, Musk's move here would have far deeper significance for the industry and, of course, for Tesla.

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.

  • 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.

  • 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.

  • 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.
