• 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.

• 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 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.

• 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.

• Popular Firefox extensions now available in 7 new locales

  Firefox is available in over 90 languages, giving millions of people around the world access to the web in words they understand. Our community of translators and localizers do this because they believe that the web belongs to everyone, not just those who speak a popular tongue.

• No Longer Lost in Translation

  You might have noticed that while Firefox supports 90 languages, many extensions and their listings on addons.mozilla.org (AMO) are only available in English.

  At present, we don’t have a way to connect extension developers with the translation community at scale, and Pontoon, Mozilla’s tool for localizing products and websites, currently only supports translating the AMO site itself.

  What we do have, however, is a desire to make translation resources available, a longstanding and active community of localizers, and friends on Mozilla’s Open Innovation team who specialize in putting the two together. Part of Open Innovation’s work is to explore new ways to connect communities of enthusiastic non-coding contributors to meaningful projects within Mozilla. Together with Rubén Martín, we ran a campaign to localize an initial group of top Firefox extensions into the 7 most popular languages of Firefox users.

• Measuring Localization Time (in CI)

  As we all know, measuring things is a good way to get concrete information. Now that Firefox CI is fully on Taskcluster this was a good opportunity to measure and see what we can learn about timing in localization tasks.

  The code that generated the following charts and data is viewable in my Github repo, though as of this writing the code is rough and was modified manually to help generate the related graphs in various configurations. I’m working on adjusting them to be more general purpose and have better actual testing around logic.

• Mozilla Reps Community

  The Reps program is working to prepare the ground for Mission Driven Mozillians and there are different tasks and issues to face for that.

• Librem 5 progress report #15

  These last few weeks, the Librem 5 team has been hard at work improving the current software stack as well as making great strides towards finalizing the development kit schematic. Here are the highlights of the exciting progress that has been made.

• Librem 5 Development Boards Won't Be Shipping Now Until At Least August

  Purism has offered a status update on their software/hardware efforts around the Librem 5 smart-phone they have been working on that is security-minded, open-source, and that they plan to begin shipping in January of 2019.

  Among the highlights from their latest update include:

  - The i.MX6 experimental software images now use their Phosh Wayland Shell and are experimenting with the PureOS base rather than Debian Buster testing.

  - In terms of the support for the i.MX8 hardware they actually want to use for the finished phone, at this stage they can now get their i.MX8 software image booting "a very basic mainline kernel" over the vendor-supplied kernel.

• Renegade Elite Mini PC Hits Indiegogo From $99

  After first being unveiled back in June 2018, the Renegade Elite single-board mini PC crowdfunding campaign via Indiegogo is now underway, offering pledges from $99. The Renegade Elite mini PC is a low-profile high-performance 4K capable 64-bit ARM computer with 4GB of LPDDR4 RAM capable of running desktop-class Linux based operating systems like Debian, Arch, Ubuntu, Fedora, OpenSUSE, Android 8.1, and more.

The bittersweet result: I may be free of the operating system release cycle, but have spent far more time fussing over my rolling distro than I ever would have fussed to upgrade from point release A to point release B. openSUSE impresses, but I probably should have (sigh …) adopted their point release distro Leap instead, or stood pat with Mint. (Although I’ll likely Tumble from here on in, now that I’ve hacked my way through the worst of the Tumbleweed learning curve.)

If also tempted by the Tumbleweed bleeding edge: Dost thou know how to make and restore a disk image, either via the fabulous free Clonezilla or a commercial equivalent? Canst thou partition a disk, and, perhaps, fix a broken boot loader? I’ll dare to name these skills as entry bars for Tumbleweed adoption, especially the first one. I figured out how to do this stuff, still judge my knowledge as barely adequate to drive Tumbleweed daily. (Although one can install the Tumbleweed ISO in a virtual machine, fiddle to one’s heart’s content.)

For many early Linux users, Slackware was their introduction. One user told me her first Linux install was Slackware—and she had to use a hex editor to fix the partition tables so that Slackware would install. Support for her hardware was added in a later release. Another got his start building the data center that would power one of the first internet-enabled real estate sites. In the mid-1990s, Slackware was one of the easiest distributions to get and didn't require a lot of effort to get IP masquerading to work correctly. A third person mentioned going to sleep while a kernel compile job ran, only to find out it had failed when he woke up.

All of these anecdotes would suggest a hard-to-use operating system. But Slackware fans don't see it that way. The project's website says the two top priorities are "ease of use and stability." For Slackware, "ease of use" means simplicity. Slackware does not include a graphical installer. Its package manager does not perform any dependency resolution. This can be jarring for new users, particularly within the last few years, but it also enables a deeper understanding of the system.

The different take on ease of use isn't the only thing unique about Slackware. It also does not have a public bug tracker, code repository, or well-defined method of community contribution. Volkerding and a small team of contributors maintain the tree in a rolling release called "-current" and publish a release when it meets the feature and stability goals they've set.

• Apache Cassandra at 10: Making a community believe in NoSQL

  Ten years ago this month, when Lehman Brothers was still just about in business and the term NoSQL wasn't even widely known, let alone an irritant, Facebook engineers open-sourced a distributed database system named Cassandra.

  Back then, the idea that huge numbers of companies would need a scalable database was almost laughable – and that grip of traditional relational database systems is reflected in the mythical moniker given to what would become one of the first of many databases designed to run on a cluster of machines.

  Named after the Greek figure who was cursed to utter the truth but was never believed, Cassandra might seem an odd choice for a system whose raison d'être is believability – but it delivered a nice dig at the stalwarts of the RDBMS world… and their trust in a false Oracle.

• Google Launches Jib, Automated Container Packaging for Java Apps

  Google has released software that could automate the packaging of a Java program so that it can be run in the cloud-native environment.

  Jib is an open-source Java “containerizer,” one that handles all the steps of packaging your application into a container image, according to Appu Goundan and Qingyang Chen, two Google engineers who co-wrote a blog post announcing the new technology.

  Created over two decades ago at Sun Microsystems, Java was introduced as a “write once, run anywhere” programming language, where all the code would be packaged in a JAR file, and run by a Java Virtual Machine on any platform. The requirements for running code anywhere have expanded with the introduction of containerization, however. Few shops are Java-only these days, and many are turning to containerization for true application portability,

• The First Open-Source Smart Contract Platform to be Started by Rootstock

  RSK Labs, formerly known as Rootstock, an Argentinian startup building the first open-source smart contract platform with a 2-way peg to Bitcoin.RSK Labs CEO Diego Gutiérrez Zaldívar on Bitcoin Smart Contracts Sidechain and Crypto Industry Challenges.

  Even though at this point of time the 2-way peg security of the RSK blockchain is still relying on a group of third parties called ‘Federation’, in the future the developers promise to bring a “trustless” automatic peg. How fast this happens to some degree depends on the overall miners support.

  The company says its goal is to add value and functionality to the Bitcoin ecosystem by enabling Ethereum-like smart-contracts, near instant payments and higher-scalability, and this past January after almost two years of development its mainnet dubbed Bamboo was finally launched.

  3. Fix wrong nr_max_tries in migrate_pending_tasks.

  This is mainly a bug fix and minor optimization release for 4.17. The rework of balance code doesn't go well, it actually make more overhead than current implement. Another rework which based on current implement is still on going, hopefully be included in next release.

• PDS-MQ CPU Scheduler Revised For The Linux 4.17 Kernel With Minor Optimizations

  Alfred Chen announced this week the release of PDS-mq 0.98s, his latest patch-set of this CPU scheduler against the Linux 4.17 upstream code-base and includes minor optimization work and bug fixes.

  The PDS scheduler stands for the "Priority and Deadline based Skiplist multiple queue scheduler" that is derived from Con Kolivas' former BFS scheduler with Variable Run Queue (VRQ) support. PDS design principles are to be a simple CPU process scheduler yet efficient and scalable. PDS-mq differs from Con Kolivas' current MuQSS scheduler.

• Add infrastructure for Vblank and page flip events in vkms simulated by hrtimer

  Since the beginning of May 2018, I have been diving into the DRM subsystem. In the beginning, nothing made sense to me, and I had to fight hard to understand how things work. Fortunately, I was not alone, and I had great support from Gustavo Padovan, Daniel Vetter, Haneen Mohammed, and the entire community. Recently, I finally delivered a new feature for VKMS: the infrastructure for Vblank and page flip events.

  At this moment, VKMS have regular Vblank events simulated through hrtimers (see drm-misc-next), which is a feature required by VKMS to mimic real hardware [6]. The development approach was entirely driven by the tests provided by IGT, more specifically the kms_flip. I modified IGT to read a module name via command line and force the use of it, instead of using only the modules defined in the code (patch submitted to IGT, see [1]). With this modification in the IGT, my development process to add a Vblank infrastructure to VKMS had three main steps as Figure 1 describes.

• Nouveau Gallium3D Moves Closer Towards OpenGL 4.5 Compliance

  While the RadeonSI and Intel i965 Mesa drivers have been at OpenGL 4.5 compliance for a while now, the Nouveau "NVC0" Gallium3D driver has been bound to OpenGL 4.3 officially.

  This Nouveau Gallium3D driver for NVIDIA "Fermi" graphics hardware and newer has effectively supported all of the OpenGL 4.4/4.5 extensions, but not officially. Originally the NVC0 problem for OpenGL 4.4 and newer was the requirement of passing the OpenGL Conformance Test Suite (CTS), which at first wasn't open-source. But now The Khronos Group has made it available to everyone as open-source. Additionally, the proper legal wrangling is in place so the Nouveau driver could become a conforming Khronos adopter under the X.Org Foundation without any associated costs/fees with Nouveau being purely open-source and primarily considered a community driver.

The DistroWatch features release announcements of new versions of hundreds of Linux and other distributions. It does host reviews of distros, podcasts, and newsletters. DistroWatch first published by Ladislav Bodnar, the founder, and maintainer, on May 31, 2001.

DistroWatch initially focused on Linux distributions. But later based on user requests, it went on adding different flavors of operating systems like BSD family, Android x86, Oracle Solaris, MINIX, and Haiku etc.

The DistroWatch presents detailed information at one place in a very convenient manner. At the time of writing this article, the DistroWatch hosted information of more than 300 active distributions (referring the list of distros populated under drop-down feature on the first page of the DistroWatch) and more than hundred in queue. It is said that the DistroWatch lives out of advertising and donation. LinuxCD.org is the first to advertise on the DistroWatch site.

Game developers are increasingly taking advantage of the growing market in Linux gaming, but that’s not always been the case, and even now some games aren’t released outside of Windows. Thanks to a clever tool called Wine, though, you can run many Windows games—and other apps, including Office—as though they were native to Linux.

Wine provides a skeletal virtual version of Windows, inside which you install extra components and perform various tweaks (for example, selecting which version of Windows you want to emulate) to get your app working. Sadly, it’s not a silver bullet that will get all your Windows games working in Linux, but it should be able to give you access to at least some of them.

Google’s Chrome OS is designed to be a relatively secure, simple operating system that’s easy to use and hard to mess up. But you can run stable channel, beta channel, or dev channel software on any Chromebook depending on whether you want the safest experience or buggy, bleeding-edge features.

There’s also an option called Developer Mode, which is different from the dev channel. It allows you to access files and settings that are normally protected and use a command shell to explore the system. It’s designed for developers and advanced users only, since it increases the chances that you’ll break your Chromebook. But enabling Developer Mode is also a prerequisite for using one my favorite Chrome OS hacks: a tool called Crouton that allows you to install Ubuntu or another GNU/Linux distribution and run it alongside Chrome OS.
