  • Debian LTS work, June 2018

    I was assigned 15 hours of work by Freexian's Debian LTS initiative and worked 12 hours, so I have carried 3 hours over to July. Since Debian 7 "wheezy" LTS ended at the end of May, I prepared for Debian 8 "jessie" to enter LTS status.

    I prepared a stable update of Linux 3.16, sent it out for review, and then released it. I rebased jessie's linux package on this, but didn't yet upload it.

  • Graphical environments in the world of IoT

    The IoT promises to bring about a revolution in the way we interact with devices around us. While many IoT devices will be hidden away, from sensors that measure manufacturing tolerances in a factory to hubs that control lighting around the home, there are a class of devices that need to provide some sort of graphical output or display to the user. Some examples include digital signage, interactive kiosks, automotive in-car entertainment gateways, smart meters, and the plethora of display screens seen on everything from washing machines to smart thermostats. All of these examples need some way to output graphics to a screen display but in an embedded environment that is not always easy.

    Linux is one of the most popular OS choices for manufacturers and solution providers to use in IoT devices and with it there are a few options available for graphical environments. From custom software to drive the display, through direct frame buffer access with toolkits such as QT, to a full X windowing server. All of these options have their pros and cons and often it is a trade-off between custom software and off-the-shelf components to speed up development. Custom software takes time and requires developers to continue to maintain a code base for the lifetime of the device, while using a graphical toolkit such as QT requires less code but comes with commercial licencing. The open source X windowing server is a popular choice but, being over 30 years old, has some shortcomings. It has been well documented that the design of X windows, although revolutionary at the time, has some security risks especially around application isolation and privilege escalation which has led to efforts to replace it by redesigning the graphical server from the ground up. One such effort is Mir.

  • Canonical releases new infographic to show how Ubuntu Linux 'connects everything'

    To highlight the ubiquitous nature of Ubuntu in particular, Canonical today releases an all-new infographic showing how this distribution "connects everything." I urge you to give it a look, as it will open your eyes to just how important Ubuntu -- and Linux overall -- really is. Apparently, this is an update to a previous infographic released in 2016, refreshed for 2018 following the release of Ubuntu 18.04 Bionic Beaver.

    Canonical has shared with us today a new infographic that shows how their Ubuntu Linux operating system is being used all over the world by big-name companies the offer their services to millions of consumers.

    More than two years ago, when Ubuntu 16.04 LTS (Xenial Xerus) was released, Canonical put together an infographic to show the world how many people use Ubuntu and on which devices. With Ubuntu 18.04 LTS (Bionic Beaver) out the door this year, they did it again and published a brand-new infographic to show the world that Ubuntu and Linux are everywhere.

Software: Newsboat, FreeFileSync, Corebird, FileZilla, nomacs, RAV1E

  • Newsboat: A Snazzy Text-Based RSS Feed Reader
    Newsboat is a sleek, open source RSS/Atom feed reader for the text console. It’s a fork of Newsbeuter. RSS and Atom are a number of widely-used XML formats to transmit, publish and syndicate articles, typically news or blog articles. Newsboat is designed to be used on text terminals on Unix or Unix-like systems. It’s entirely controlled by the keyboard. The software has an internal commandline to modify configuration variables and to run commands.
  • FreeFileSync – Data Backup and File Synchronization App
    FreeFileSync is a free data backup and file synchronization app which is available in Linux systems enables you to seamlessly sync your backup data with the source data. When you take a backup of your HD, or any other disk drive, you should keep it in sync for the file changes you do from time to time. It is often difficult to remember which file/directories you have changed/deleted/updated since the last backup. FreeFileSync solves that problem and it can determine and sync only those changed/deleted/updated files in your backup.
  • Corebird Twitter Client – to Stop Working
    Corebird, the best native GTK+ Twitter client available for Linux desktops including Ubuntu will stop working on August 2018. This has been recently reported by the Corebird developer in patreon as well as in GitHub. This is mainly due to the policy change from Twitter which will remove UserStream API which is used by Corebird and other third party Twitter clients. In the patreon post, the developer stated that, the new API by Twitter named Accounts Activity API is too difficult to implement and he may not have much time available for development.
  • FileZilla – Best FTP Client for Linux, Ubuntu Releases version 3.34.0
    FileZilla is a free and open source FTP client available for Ubuntu, Mint and other Linux systems. FileZilla is the go-to software when you need a FTP client for your need.

  • nomacs 3.10.2
    nomacs is licensed under the GNU General Public License v3 and available for Windows, Linux, FreeBSD, Mac, and OS/2.
  • RAV1E: The "Fastest & Safest" AV1 Encoder
    Following the news about VP9 and AV1 having more room to improve particularly for alternative architectures like POWER and ARM, a Phoronix reader pointed out an effort that Mozilla is behind on developing the "rav1e" encoder. AV1 up to this point for encoding on CPUs has been - unfortunately - extremely slow. But it turns out Mozilla and others are working on RAV1E as what they are billing as the fastest and safest AV1 encoder. RAV1E has been in development for a while now but has seemingly flown under our radar.

Red Hat Looks Beyond Docker for Container Technology

While Docker Inc and its eponymous container engine helped to create the modern container approach, Red Hat has multiple efforts of its own that it is now actively developing. The core component for containers is the runtime engine, which for Docker is the Docker Engine which is now based on the Docker-led containerd project that is hosted at the Cloud Native Computing Foundation (CNCF). Red Hat has built its own container engine called CRI-O, which hit its 1.0 release back in October 2017. For building images, Red Hat has a project called Buildah, which reached its 1.0 milestone on June 6. Read more

Containers: The Update Framework (TUF), Nabla, and Kubernetes 1.11 Release

  • How The Update Framework Improves Software Distribution Security
    In recent years that there been multiple cyber-attacks that compromised a software developer's network to enable the delivery of malware inside of software updates. That's a situation that Justin Cappos, founder of The Update Framework (TUF) open-source project, has been working hard to help solve. Cappos, an assistant professor at New York University (NYU), started TUF nearly a decade ago. TUF is now implemented by multiple software projects, including the Docker Notary project for secure container application updates and has implementations that are being purpose-built to help secure automotive software as well.
  • IBM's new Nabla containers are designed for security first
    Companies love containers because they enable them to run more jobs on servers. But businesses also hate containers, because they fear they're less secure than virtual machines (VM)s. IBM thinks it has an answer to that: Nabla containers, which are more secure by design than rival container concepts. James Bottomley, an IBM Research distinguished engineer and top Linux kernel developer, first outlines that there are two kind of fundamental kinds of container and virtual machine (VM) security problems. These are described as Vertical Attack Profile (VAP) and Horizontal Attack Profile (HAP).
  • [Podcast] PodCTL #42 – Kubernetes 1.11 Released
    Like clockwork, the Kubernetes community continues to release quarterly updates to the rapidly expanding project. With the 1.11 release, we see a number of new capabilities being added across a number of different domains – infrastructure services, scheduling services, routing services, storage services, and broader CRD versioning capabilities that will improve the ability to not only deploy Operators for the platform and applications. Links for all these new features, as well as in-depth blog posts from Red Hat and the Kubernetes community are included in the show notes. As always, it’s important to remember that not every new feature being released is considered “General Availability”, so be sure to check the detailed release notes before considering the use of any feature in a production or high-availability environment.
