      • Best Linux Laptops That You Can Buy For Home and Office Usage

        If you are looking for the best Linux laptops for your home and office usage, then you are in the right place. As you already know, Linux is becoming mainstream day by day. Normally mass users go for Windows or macOS because of the convenience and hardware compatibility. But with the hard work of the open-source community, Linux is improving too. You can run Linux on an ARM or x86 hardware that is compatible with Windows. Rather you are getting more flexibility and security with Linux.

        This is why people tend to use Linux in workplaces. And, this leads us to the portability aspect of Linux computers. Of course, you can use any portable machine, especially a laptop, to run Linux natively. But some laptops are optimized specially for running Linux and open-source software. They are also equipped with Linux-compatible drivers. You will be surprised to know that some laptops even come with Linux preinstalled.

      • Linux Kernel’s Preliminary Rust Code Seeing 64-bit POWER Support

        Excitement is building around initial support for the Rust language within the Linux kernel that arrived in Linux-Next and is now seeing more developer interest.

        This very preliminary infrastructure work around supporting Rust code within the Linux kernel and an example module in tow continues to mature within Linux-Next while awaiting to see if it will try to be mainlined in a few weeks for the 5.13 cycle. Now that activity is happening, more upstream kernel developers are taking note.

      • Linus Torvalds on where Rust will fit into Linux

        This isn’t just a theory being pushed by Rust enthusiasts. A great deal of Rust in Linux is already being pushed out into the market. Amazon Web Services (AWS) recently released Bottlerocket Linux for containers and it has a great deal of Rust in it.

        Sylvestre Ledru, a Mozilla director by day and Debian Linux developer by night, has ported a Rust version of Coreutils to Linux using the LLVM compiler infrastructure and its Clang C language front-end and tooling infrastructure. Coreutils are the GNU shell core utilities. With these, Ledru has booted Linux and run the most popular Debian packages. This isn’t, Ledru admits, production-ready yet, but with a lot of elbow grease, it works today. Eventually, it may replace GNU Coreutils.

        Why do any of this in the first place? Rust is popular because it lends itself more easily to writing secure software. Samartha Chandrashekar, an AWS Product Manager, said it “helps ensure thread safety and prevent memory-related errors, such as buffer overflows that can lead to security vulnerabilities.” Many other developers agree with Chandrashekar.

      • AMD Sends Out Latest Patches For HMM-Based SVM Memory Manager – Phoronix

        Published back in January was the initial work on a HMM-based SVM memory manager for the open-source Radeon compute stack. A second version of that work is now available as it continues working towards the mainline kernel.

        This Shared Virtual Memory (SVM) memory manager implementation makes use of the Linux kernel’s modern Heterogeneous Memory Management (HMM) code. As part of working on continuing to advance their ROCm compute stack and preparing for their big HPC/super-computer deployments using a combination of AMD EPYC CPUs and Radeon GPUs, this SVM memory manager is being worked on. This work is critical for heterogeneous computing in letting the GPU transparently access program addresses coherently with the CPU.

      • Linux Kernel Patches Sent Out For A More Powerful Virtual M68k Machine – Phoronix

        Right now when it comes to Motorola 68000 “m68k” emulation with Linux the most powerful target is the Quadra 800 that is limited to just 1GB of RAM and specific interfaces. But on the way is the new “Virtual M68k Machine” that is much more powerful.

        The Macintosh Quadra 800 is from 1993 with its Motorola 68040 running at 33MHz with 8MB of RAM. Linux and QEMU has supported the Quadra 800 as an emulated target but this new Virtual M68k Machine will allow for greater capacity and more modern amenities. The QEMU side support for the new Virtual M68k Machine is coming with QEMU 6.0 while the Linux kernel bits for this virtual machine were sent out today in patch form.

        • Mesa 21.1 Will Aim To Be Out By Mid-May – Phoronix

          With Mesa 21.0 released earlier this month following a one month delay, the Mesa 21.1 release calendar has now been published for that next quarterly feature release.

          Mesa 21.1 has been under development since 21.0 was branched off in January and as such a lot of work has already accumulated while there still are a few weeks to build up more feature code. Mesa 21.1 is planned for branching and the first release candidate around 14 April. Following that mid-April branching, weekly release candidates will continue until the official release is ready.

        • Mesa Could Fork Older “Classic” Display Drivers Out To A Separate “Mesa Classic-LTS” Branch – LinuxReviews

          Dylan Baker, release-manager for the Mesa graphics stack used by all the GNU/Linux distributions, is proposing to rid the Mesa of older “classic” display drivers by moving them to a separate “classic-lts” branch. Users of integrated Intel graphics provided by chips prior to Broadwell would have to switch to the new “classic-lts” graphics library to keep their computers working if Mesa goes forward with Bakers proposal.

          [...]

          The story on the Intel side is a bit different. The modern Intel Iris graphics driver can only be used with Broadwell-series hardware or newer. The Intel Haswell was launched in 2013. The integrated graphics hardware on those chips can only be used with the “classic” i965 OpenGL driver. Many people still use Haswell, and even older chips, today. I have a family-member who uses one. That person does not use GNU/Linux, or free software in general, so that persons life would not be affected if Mesa removes support for Haswell-era hardware from the from the main branch. People who do use free software operating systems would have to either switch to the proposed new “classic-lts” Mesa branch or a proprietary operating system like Microsoft Windows.
          Switching to a “classic-lts” Mesa branch may not be that difficult for those who would need to do so – depending on what GNU/Linux distributions decide to do. The “GL Vendor-Neutral Dispatch library” (libglvnd) makes it possible to have several OpenGL libraries installed side-by-side. Distributions could simply ship both the modern Mesa branch and the classic-lts and none of the affected users would notice that their machine happens to be one using “classic-lts”.

        • Proposal Raised For Dropping Mesa’s Classic OpenGL Drivers From Mainline This Year – Phoronix

          It’s been proposed in the past but never acted upon yet but the idea of dropping/retiring Mesa’s “classic” OpenGL drivers from the mainline code-base and letting them potentially live on in an “LTS” branch has once again been brought up.

          Mesa developer Dylan Baker has brought up the idea of removing the classic drivers from Mesa master following next quarter’s 21.1 release. The Mesa 21.1 branch would then be forked after Mesa 21.1 is EOL’ed to create a “classic-lts” branch. That classic-lts branch would disable the Gallium3D and Vulkan drivers to just focus on these classic drivers. That branch in turn would only see new build and critical bug fixes. Thanks to GLVND, these classic LTS drivers could be installed in parallel along with newer versions of Mesa.

        • Alejandro Piñeiro: Improving v3dv pipeline caching

          After some investigation, we found that the game was calling ClearAttachment twice every frame. The implementation of those ClearAttachments was relying on a full job with a graphics pipeline. On v3dv by default any pipeline is created with a pipeline cache (provided by the user, or a default pipeline). On v3dv (and in general any Vulkan driver) the main cached data are the compiled shaders, so the main objective of the pipeline cache is avoiding full shader re-compilation on compatible pipelines that are used really often. Why was that time spent on linking shaders?

          The issue was that for each pipeline lookup on the pipeline cache we were doing two cache lookups. The first one against a cache with the shaders in NIR, that is the main intermediate representation for shaders in Mesa (more info about intermediate representation here). And then we used those shaders to fill up the key for a second cache lookup, that if succesful, will return the compiled shader on Broadcom (QPU) assembly format.

          The reason of this two-step lookup is that to compile a shader we call the common (for both OpenGL and Vulkan) Broadcom compiler, and we use some data structures that contain info that will affect the compilation (like if blending is enabled). When we implemented the pipeline cache support, for simplicity, we used the same data structures as part of the cache key. But as such keys were filled with info coming from the NIR shaders, those needed to be linked together on the case of the graphics pipelines.

          When we analyzed how to improve it, we realized that in order to identify the compiled shader, we don’t really need the NIR shaders, as the info derived from them are implicit to the SPIR-V shaders provided to create the pipeline. Those NIR shaders are only really needed to compile the shader. The improvement here was using a different data structure as part of the cache key, and replace the two-cache-lookup with a one-cache-lookup. We needed to do some additional changes, as there were parts of the code that assumed that the NIR shaders would be available, but now if possible we are skipping getting them.

        • V3DV Pipeline Caching Work Leads To Greater Raspberry Pi Vulkan Performance

          Alejandro Piñeiro Iglesias of Igalia wrote a new blog post today outlining the V3DV work on pipeline caching to further enhance the performance. By going from a two-cache to one-cache lookup and other improvements, one of the V3DV test cases dropped from taking 11.4 seconds down to 0.8 seconds. (Meanwhile no pipeline caching yielded a 125 second run-time). With some games/software like the Unreal Engine 4 Shooter demo, it meant several FPS gains.

        • Radeon ROCm 4.1 Released – Still Without RDNA GPU Support

          ROCm 4.0 released back in December with “CDNA” GPU support while now ROCm 4.1 has been released as the newest quarterly feature release to this open-source Radeon compute stack focused primarily on HPC/data-center needs.

          ROCm 4.1 delivers on several new features but before anyone asks, no, there still is not any GFX10/RDNA GPU support for either the Radeon RX 5000 or RX 6000 series. The ROCm compute support remains focused on Vega GPUs and CDNA GPUs, the AMD Instinct MI100. There remains full-support-but-not-guaranteed coverage for Polaris and Hawaii GPUs. Those with the newer RDNA consumer GPUs wanting to use the Radeon Open eCosystem stack, you are left waiting still with ROCm 4.1. The ongoing delay in RDNA GPU support for ROCm appears to be due to AMD’s focus on getting everything up to par with the CDNA GPU support with forthcoming super-computer deployments and other big ticket HPC customers.

      • The Older v2 Tor Onion Domain Name Format Is Axed In The Latest Tor Alpha Release

        The Tor Onion Router has had support for location hidden services with a special .onion address for a really long time. Support for .onion services was initially introduced in 2005. Tor dropped the first .onion format shortly after it was introduced and replaced it with a v2 format that is still widely used today. A new and improved v3 format was introduced in January 2015. A few services use it, most don’t. Those who don’t will soon be forced to as support for the older v2 .onion format was removed with the release of Tor 0.4.6.1-alpha.

      • How to Install a Desktop Environment (GUI) on an Ubuntu 20.04 Server – ByteXD

        In Linux, this GUI (Graphical User Interface) is referred to as a Desktop Environment.

        A desktop environment is a collection of components that make up the graphical user interface (GUI) – it’s made out of widgets, icons, toolbars, wallpapers, and more. I think of it as a theme, but going even further than that. A desktop environment changes the look and feel of your system much more than a theme.

        What’s more, you have quite few great options to choose from.

        Linux servers don’t come with a desktop environment installed by default, and in most cases it’s not needed. However there are cases when you do require a graphical user interface on your Linux server to get your work done.

      • How to Connect your Android phone to Zorin OS with Zorin Connect – Real Linux User

        In the relatively limited number of years that I have been enthusiastically and intensively working with Linux and kept a close eye on everything related to this platform, I saw some Linux distributions rapidly growing into more and more user-friendly platform that move towards operating system that in my opinion should undoubtedly appeal to regular non tech savvy users who just want to do regular stuff on their computer or be creative on their computer without going through technical hurdles. In the first years I mainly used Linux Mint, a beautiful Linux distribution for both beginners and advanced users. But as a blogger I want to support a broad target group of starting Linux users, so I also look at other Linux distributions that I think could be very suitable for beginning and non techy users. One of those distributions, which I now also use as my primary platform, is Zorin OS 15.3. Zorin OS is a beautiful and very accessible and friendly operating system and offers a lot of functionality directly out of the box, which in other distributions often has to be installed or adjusted afterwards. One of these functionalities is the connection between your Zorin OS computer and your Android phone, which is supported in an impressive way through Zorin Connect. In this blog I will explain How to Connect your Android phone to Zorin OS with Zorin Connect.

        After we successfully released Xfce 4.16 as an early Christmas gift to all users last year I personally fell into the typical “post release fatigue” (PRF). On the one hand I was exhausted, on the other hand that’s how far our plans had taken us so there were no clear next steps we had settled on (apart from taking a break and recharging :)).

        So what’s been going on since then…

        Xfce 4.16 maintenance

        First of all, we’ve done quite a few maintenance release of 4.16 to ensure it’s stability. We already provided lots of bugfix releases of 4.14 – some even very recently (Desktop, Appfinder) – but it looks like 4.16 may end up being (at least: among) the best maintained Xfce release so far.

        • Bringing FIDO2 device support to sandboxes

          Hardening user logins with 2FA is becoming must-feature of Web services; most of the services I use daily (such as GitLab instances) are already enabling it. Although it’s a bit cumbersome to enter secondary factor manually, using hardware tokens (such as FIDO2 authenticators) simplifies the process to a single tap, also making the entire authentication more secure based on public key cryptography.

          On the client side, major browsers provide built-in support for hardware tokens (at least CTAP1), though sandboxed applications cannot benefit from this without allowing direct access to the host hardware. To improve the situation, we had several discussions in forums last year and somehow reached a rough consensus: we need a proxy for those authenticator devices.

While the Xfce and GNOME editions are shipping with the same Xfce 4.16 and GNOME 3.38 releases that were available in Manjaro Linux 20.2 “Nibia,” the KDE Plasma edition has been upgraded to the latest KDE Plasma 5.21 desktop environment series.

        • Download Manjaro Linux 21 Ornara with GNOME, Xfce, and KDE Plasma now!

          One of the most popular Linux-based desktop operating systems these days is the Arch-based Manjaro. Following a short testing period, version 21 of that distribution is now available for download. Code-named “Ornara,” Manjaro 21 uses the fairly new Linux kernel 5.10 LTS.

          Manjaro Linux 21 can be had with your choice of three desktop environments — GNOME 3.38, KDE Plasma 5.21, and Xfce 4.16. All three are great, but unfortunately, GNOME 40 has still not been finalized, so it is (obviously) not included here. If you do want to try an early version of the upcoming GNOME 40, you can download the recently released Fedora 34 Beta.

          “We are happy to publish our latest stable release 21.0 we named Ornara. Our last release Nibia was from January and a lot of things changed between those releases. For once, we dropped Gnome Initial Setup routine from our ISOs. It was nice to try out, but the feedback overall was not so great. Since we also have optional OEM ISOs for our manufacturers, we see no need to further investigate into GIS,” says The Manjaro Development Team.

        • Manjaro 21.0 Released With Linux 5.10 Kernel, GNOME 3.38 + Xfce 4.16 + KDE Plasma 5.21

          Manjaro 21.0 is out today as the newest feature release to this popular desktop Linux distribution built atop Arch Linux.

          Manjaro 21.0 is powered by the Linux 5.10 LTS kernel while continuing to keep Linux 5.4 LTS around for those wanting it on older hardware. Manjaro 21.0 is also making use of Pamac 10 graphical package manager, which released at the end of last year with performance improvements, optimized database interaction, systemd dynamic users, and other new features.

        • Fedora 34 Beta Released With PipeWire In Action, GNOME 40 Desktop

          Fedora 34 Beta is out today as the march is on towards this latest installment of this Red Hat sponsored Linux distribution.

          It should come as no surprise with Fedora continuously living on the bleeding-edge of open-source innovations, but Fedora 34 is going to be another big and exciting release. Particularly on the Fedora Workstation front, Fedora 34 is bringing GNOME 40 to the desktop, Btrfs transparent file-system compression is enabled, PipeWire is by default in place of PulseAudio, there is a new i3 desktop spin, and many other Fedora 34 changes.

          Fedora 34 beta is out this morning while the official F34 release is expected before the end of April.

        • Fedora Linux 34 Beta now available

          Today, the Fedora Project, a global community that works to help advance free and open source software, is pleased to announce the availability of Fedora Linux 34 Beta, the latest version of the Fedora Linux operating system. Fedora Linux 34 Beta continues the Fedora Project’s emphasis on delivering editions, each designed to address specific use cases for modern developers and IT teams.

          Fedora Linux 34 Beta sees a continued trajectory for a more coherent desktop interface for a better user experience with GNOME 40. We also continue to foster the development of emerging Fedora editions like Fedora CoreOS to better address the future of cloud-native, containerized infrastructure and development. Fedora Linux 34 Beta enables a coherent set of packaged application updates, streamlining new versions and enabling users to revert to previous versions.

        • Fedora Linux 34 beta rolled out

          As Matthew Miller, Red Hat’s Fedora Project Leader, has explained, “Fedora integrates thousands of ‘upstream’ open-source projects into a unified distribution on a six-month release cadence, and every so often Red Hat takes that collection, forks it off, and produces RHEL.” That remains the same.

          So, what does the new Fedora bring us? Besides the desktop, which is often the first and sometimes the only thing users think of, Fedora also comes with different editions, each designed to address specific use cases for modern developers and IT teams. This includes Fedora CoreOS. This version addresses the needs of cloud-native, containerized developers.

          As for the desktop, this new version uses the new GNOME 40 desktop. Its enhancements include a better desktop arrangement for search, windows, workspaces, and applications. It also includes multi-monitor improvements. It also enables users to choose between workspaces on only their primary displays or workspaces on all displays.

          If you’ve played around with Kubernetes, you are aware of the rapid evolution of the most widely used container orchestration platform. Red Hat OpenShift is an enterprise-ready application platform built on Kubernetes and ready for production environments. With OpenShift 4, Red Hat aims to provide new releases at a frequent cadence. To help keep on top of all of the new changes, and to help and sysadmins and DevOps people who have to deal with multiple versions of your Kubernetes platform at the same time, I wrote this article hoping to help you more easily overcome challenges you may face.

        • Building a container by hand using namespaces: The mount namespace | Enable Sysadmin

          This article looks at the mount namespace and is the third in the Linux Namespace series. In the first article, I gave an introduction to the seven most commonly used namespaces, laying the groundwork for the hands-on work started in the user namespaces article. My goal is to build out some fundamental knowledge as to how the underpinnings of Linux containers work. If you’re interested in how Linux controls the resources on a system, check out the CGroup series, I wrote earlier. Hopefully, by the time you’re done with the namespaces hands-on work, I can tie CGroups and namespaces together in a meaningful way, completing the picture for you.

          For now, however, this article examines the mount namespace and how it can help you get closer to understanding the isolation that Linux containers brings to sysadmins and, by extension, platforms like OpenShift and Kubernetes.

        • Using Red Hat’s support tool at the command line to solve real-world problems

          The support tool allows you to interact with the Red Hat knowledge base, support tickets, analyze log files, and even set site-wide configuration options, all from the command line! At first glance, that may not seem like a big deal, but consider these real world scenarios.

          You come across some issues getting Nginx to play nice with your Red Hat Enterprise Linux (RHEL) server. You remember that there was a Knowledge Base (KB) article about that very same topic. One problem though: Copy+Paste doesn’t work between your browser and the remote virtual machine (VM) console you are working on. No problem! Install the redhat-support-tool, login to your Access account, search for that KB article, and copy that long command and all its options within your terminal!

          Here’s another scenario. You’ve run into some issues with a kernel module. You’re stumped. You want to put your support subscription to good use and ask one of our amazing engineers to give you a fresh perspective. No problem! Create a ticket from the terminal of your affected system, run an SOS report, and attach some debug logs all to the same ticket without ever leaving the terminal!

          Linux distros are still primarily downloaded via online mirrors and stuffing them with apps will increase their size, making the downloads unfeasible for many people with bandwidth caps or slower connection speeds. And to many, the apps would just be useless bloat.

          They are a bit late in doing so, but Ubuntu developers are working to figure out if it makes sense to run FSCK “file-system check” at boot time. It turns out Ubuntu Server and other Ubuntu installations making use of their Curtin installation component haven’t enabled the functionality for FSCK at boot but now they are (re)visiting the matter.

          This bug report from 2018 points out that Ubuntu Server is setting “fs_passno” to 0 which means no FSCK at boot. This is a regression and change in behavior from prior Ubuntu Server installs to Ubuntu 18.04 and beyond where they introduced their new Curtin-based Subiquity installer where FSCK is not happening. That bug wasn’t touched since early 2019 but is now being re-visited by Ubuntu developers.

          With an aim to expand the Linux app ecosystem, Ubuntu desktop engineering manager Ken VanDine has popped up in marketing material for Flutter to say that Google’s cross-platform framework is Canonical’s “default choice for future desktop and mobile apps”.

          Flutter is a framework using the Dart language that targets Android, iOS, Windows, Linux, macOS, and web applications – though the macOS and Linux versions are “considered beta quality”.

          Despite that limitation, Canonical declared last month that it would build new desktop installers in Flutter. Now the company has gone further, pointing developers to a statement by VanDine, who said that “Flutter is the default choice for future desktop and mobile apps created by Canonical” and that the Flutter SDK is available from the Snap Store, making it easy for developers to get started.

        • How does Ubuntu 16.04 entering Extended Security Maintenance (ESM) affect snap publishers? | Ubuntu

          At the end of April, Ubuntu 16.04 LTS will reach the end of its five years of mainstream support and enter the Extended Security Maintenance (ESM) phase. If you’re a snap developer, and you have built or based your snaps on Ubuntu 16.04 (Xenial) packages and libraries, you may want to know how this milestone affects you. This blog post outlines the details of the change, the implications, and the future roadmap.

          [...]

          To be able to continue building using the ESM base for local and on-premise builds, snap publishers and developers will need to obtain UA tokens. These tokens are free for all community users, for up to three machines, and up to 50 machines for Ubuntu members.

          • Firefox 87 introduces SmartBlock for Private Browsing

            At Mozilla, we believe that privacy is a fundamental right and that everyone deserves to have their privacy protected while they browse the web. Since 2015, as part of the effort to provide a strong privacy option, Firefox has included the built-in Content Blocking feature that operates in Private Browsing windows and Strict Tracking Protection Mode. This feature automatically blocks third-party scripts, images, and other content from being loaded from cross-site tracking companies reported by Disconnect. By blocking these tracking components, Firefox Private Browsing windows prevent them from watching you as you browse.

            In building these extra-strong privacy protections in Private Browsing windows and Strict Mode, we have been confronted with a fundamental problem: introducing a policy that outright blocks trackers on the web inevitably risks blocking components that are essential for some websites to function properly. This can result in images not appearing, features not working, poor performance, or even the entire page not loading at all.

          • In March, we see Firefox 87

            Nearing the end of March now, and we have a new version of Firefox ready to deliver some interesting new features to your door. This month, we’ve got some rather nice DevTools additions in the form of prefers-color-scheme media query emulation and toggling :target pseudo-classes, some very useful additions to editable DOM elements: the beforeinput event and getTargetRanges() method, and some nice security, privacy, and macOS screenreader support updates.

          • Firefox 87 and Firefox ESR 78.9

            Firefox 87 has been released. This version introduces SmartBlock, “a new intelligent tracker blocking mechanism for Firefox Private Browsing and Strict Mode.”

          • Mozilla Accessibility: VoiceOver Support for macOS in Firefox 87

            Screen readers, an assistive technology that allows people to engage with computers through synthesized speech or a braille display, are available on all of the platforms where Firefox runs. However, until today we’ve had a gap in our support for this important technology. Firefox for Windows, Linux, Android, and iOS all work with the popular and included screen readers on those platforms, but macOS screen reader support has been absent.

            For over a year the Firefox accessibility team has worked to bring high quality VoiceOver support to Firefox on macOS. Last August we delivered a developer preview of Firefox working with VoiceOver and in December we expanded that preview to all Firefox consumers. With Firefox 87, we think it’s complete enough for everyday use. Firefox 87 supports all the most common VoiceOver features and with plenty of performance. Users should be able to easily navigate through web content and all of the browser’s primary interface without problems.

          • Firefox 87 Released with Privacy Tweaks, Leaner Library Menu

            Firefox 87.0 is the latest stable release and includes a modest set of changes. The update is available for Windows, macOS, and Linux. Ubuntu users will receive the update automatically at some point in the next few days.

            So what’s new?

            Well, Mozilla promise fewer website breakages when you use Firefox’s Private Browsing mode or have the ‘strict’ Enhanced Tracking Protection enabled. This is thanks to something called SmartBlock which provides stand-in scripts to ensure that well-known websites load both properly and promptly.

          • Firefox 87 Released with SmartBlock to Less Breakage in Private Browsing

            Mozilla Firefox 87.0 was released today with further efforts on improving user privacy.

            Firefox 87 introduced SmartBlock, a new intelligent tracker blocking mechanism for Private Browsing and Strict Tracking Protection Mode. By providing local stand-ins for blocked third-party tracking scripts, you’ll encounter less website breakage while fully protected from trackers.

            As today’s web is on the way to becoming https-only and browsers are taking steps to improve user privacy, the 87 browser release introduced new default HTTP Referrer policy instead of ‘no-referrer-when-downgrade’.

          • Firefox 87 Released With Privacy Improvements But Backs Out AVIF

            Mozilla Firefox 87.0 is out today as the newest release of this open-source, cross-platform web browser.

            Firefox 87 continues the ongoing trend of privacy and security improvements. Firefox 87 uses Mozilla’s new default HTTP Referrer policy, less website breakage when running in Privacy Browsing and Strict Enhanced Tracking Protection, and a variety of other improvements. Firefox 87.0 also comes with various accessibility improvements, full support for the macOS screen reader, and many bug fixes.

            Originally slated to be in Firefox 87 was AVIF image decoding support.

          • Welcome SmartBlock: Script Surrogates for the masses!

            Today Mozilla released Firefox 87, introducing SmartBlock, a new feature which “intelligently fixes up web pages that are broken by our tracking protections, without compromising user privacy [...] by providing local stand-ins for blocked third-party tracking scripts. These stand-in scripts behave just enough like the original ones to make sure that the website works properly. They allow broken sites relying on the original scripts to load with their functionality intact.”

            As long time NoScript users may recall, this is exactly the concept behind “Script Surrogates”, which I developed more than ten years ago as a NoScript “Classic” module.

            In facts, in its launch post Mozilla kindly wants “to acknowledge the NoScript and uBlock Origin teams for helping to pioneer this approach.”.

            It’s not the first time that concepts pioneered by NoScript percolate into mainstream browsers: from content blocking to XSS filters, I must admit it gets me emotional every time :)

        • Richard Stallman returns to the Free Software Foundation

          Richard Stallman, the founder and former president of the Free Software Foundation (FSF), has announced he is returning to the foundation as a board member.

          Stallman founded the FSF in 1985 and was the acting president until about 18 months ago when he resigned over comments he made regarding Jeffrey Epstein and his alleged victims.

          At the time, Stallman said he was resigning over “a series of misunderstandings and mischaracterizations.”

          The announcement was made in a talk at LibrePlanet this week. “I’m now on Free Software Foundation’s board of directors once again,” he said. “Some of you will be happy at this, and some might be disappointed, but who knows. In any case, that is how it is. And I am not planning to resign a second time.”

          Richard M. Stallman recently announced that he will be returning to the board of directors of the Free Software Foundation (FSF), a statement that the FSF has not denied. We believe it is inappropriate for Stallman to hold any leadership position in the free and open source software community.

          Richard Stallman founded the FSF in 1985. He was the acting president until about 18 months ago when he resigned over comments he made regarding Jeffrey Epstein and his alleged victims.

          Richard Stallman has always been a divisive figure. On one hand, he’s been the biggest champion of free software for decades. On the other hand, his rather absolutist take on free software has helped to create a faction within the Linux and open source communities wherein it is looked down upon to use any software that isn’t free.

          Stallman announced the news during a live stream for the FSF project LibrePlanet. He also mentioned that the announcement was meant to be made with a more formal video, but that “it didn’t get finished.”

        • Richard Stallman Is Finally Back In The FSF

          Back in 2019 Richard Stallman was removed from the FSF after some poorly thought out comments but in a recent announcement at LibrePlanet 2021 he has been reinstated to the Free Software Foundation board of directors.

          The first major release of the Crystal programming language happened this week as the project hit version 1.0. The much anticipated language has been created with the aims of offering the speed of C/C++ but with a programmer-friendly syntax as readable and easy to understand as Ruby.

          Crystal has been under development for around a decade and is described as a general-purpose, object-oriented programming language. It is a compiled language with static type-checking and a syntax heavily influenced by the Ruby language.

          • Subject Verb Object notation; declarative Perl without the framework

            If you’ve read Curtis “Ovid” Poe’s articles on the declarative framework for Tau Station Link and Link, you are undoubtedly aware of many of the benefits this style of programming can bring. It decouples the “what” from the “how”, encourages discrete functions and prevents the OO trap of “god objects”. The result is software that is easy to test, robust and very flexible. Inserting steps, reording steps etc… are done much easier and more clearly than trying to figure this out in 300 lines of imperative code with four to six level deep if-else chains with for loops mixed in for good fun. However, the framework is tightly coupled to the game in spots and has a few other issues that make it not ready for general use.

          • Django vs. SQLAlchemy Comparison

            As more and more technology is developed and improved over time, the number of users accessing the internet grows even more, and as a result of that, the amount of data that businesses and organizations have to deal with is growing exponentially. For a company to be successful, it needs to have tools and infrastructure that can deal with these large sets of data easily. This is exactly where the database comes into the picture which is mainly designed for the storage and collection of data. Moreover, its organized form allows users to easily manage and access the dataset. Database themselves require a management system that allows them to store and provide access to the data. Mostly, the language SQL is used to perform operations in a database, however, as your application grows and becomes more complex, it becomes extremely difficult to have an idea as to what exactly each operation is doing.

            An alternative to this that was developed was the ORM (Object Relational Mapping) frameworks that actually create a bridge in connecting the database and the programming language that you prefer using in creating your application. With Python being one of the most popular programming languages this year, we shall, therefore, take a look at and compare the pros and cons of two of its most popular and widely used ORMs, Django and SQLAlchemy, in this article.

            Some time ago, my rather old (zsh!) script for checking the current weather from the weather service Yr.no broke, after some looking around I found a new alternative called Forecast.

            The script is written in Bash, and it’s pretty straightforward. It requires bash, curl and xsltproc.

          • How to Use until Loop in Your Shell Scripts

            In bash for, while, and until are three loop constructs. While each loop differs syntactically and functionally their purpose is to iterate over a block of code when a certain expression is evaluated.

            Until loop is used to execute a block of code until the expression is evaluated to be false. This is exactly the opposite of a while loop. While loop runs the code block while the expression is true and until loop does the opposite.

            [...]

            You can use a break and continue statements inside while loop. The break statement will exit out of the loop and will pass the control to the next statement while the continue statement will skip the current iteration and start the next iteration in the loop.

            I am using the same infinite loop example. Here when the count is equal to five continue statement will jump over to the next iteration skipping the rest of the loop body. Similarly, the loop breaks when the count is equal to or greater than 10.

          • How to Use Supercharged Sorts in JavaScript

            And the answer is, of course, sure. Absolutely. The way Array.filter() works in JavaScript, it’s chainable. That means, when the first .filter() function returns, it can be fed straight into a second .filter(), and to as many filters as you like.

            But if we want to sort by more than one property, that seems a little trickier. After all, if we sort by one property, then sort by a second, we’ve lost the first.

            How about if we use something like .reduce() instead? We could use that to reduce the array to an object whose properties are the first sort values, then set each of those properties to an array of items containing those values, and sort them!

          • 3 new Java tools to try in 2021 | Opensource.com

            Despite the popularity of Python, Go, and Node.js for implementing artificial intelligence and machine learning applications and serverless functions on Kubernetes, Java technologies still play a key role in developing enterprise applications. According to Developer Economics, in Q3 2020, there were 8 million enterprise Java developers worldwide.

            Although the programming language has been around for more than 25 years, there are always new trends, tools, and frameworks in the Java world that can empower your applications and your career.

            The vast majority of Java frameworks are designed for long-running processes with dynamic behaviors for running mutable application servers such as physical servers and virtual machines. Things have changed since Kubernetes containers were unleashed in 2014. The biggest issue with using Java applications on Kubernetes is with optimizing application performance by decreasing memory footprints, speeding start and response times, and reducing file sizes.

            One of the biggest challenges security professionals face is making security simple for their organization’s workforce, the report states. “Having a strong technical or security background can be beneficial because it provides familiarity with the common technologies and behaviors” related to potential risks. However, the report states, “being ‘too technical’ can mean that individuals lack the skills to effectively communicate those risks or meaningfully engage employees.” To address this potential communication gap, the report recommends working with others to craft messaging that is easily understood.

          • WebAssembly Security, Now and in the Future

            WebAssembly is, as we explained recently, a binary format for software written in any language, designed to eventually run on any platform without changes. The first application of WebAssembly is inside web browsers, to make websites faster and more interactive. Plans to push WebAssembly beyond the Web, from servers of all sorts to the Internet of Things (IoT), create as many opportunities as security issues. This post is an introductory overview of those issues and of the WebAssembly security model.

            [...]

            WebAssembly code runs closed into a sandbox managed by the VM, not by the operating system. This gives it no visibility of the host computer, or ways to interact directly with it. Access to system resources, be they files, hardware or internet connections, can only happen through the WebAssembly System Interface (WASI) provided by that VM.

            The WASI is different from most other application programming interfaces, with unique security characteristics that are truly driving the adoption of WASM on servers/edge computing scenarios, and will be the topic of the next post. Here, it is enough to say that its security implications greatly vary, when moving from the web to other environments. Modern web browsers are terribly complex pieces of software, but lay on decades of experience, and of daily tests from billions of people. Compared to browsers, servers or IoT devices are almost uncharted lands. The VMs for those platforms will require extensions of WASI and thus, in turn, surely introduce new security challenges.

              Three recently unearthed vulnerabilities in the Linux kernel, located in the iSCSI module used for accessing shared data storage facilities, could allow root privileges to anyone with a user account.

              [...]

              According to SC Media, if an attacker already had the execution on a box, either because you have a user account on the machine, or you’ve compromised some service that doesn’t have repaired permissions, you can do whatever you want.

              The vulnerabilities were spotted at the mythically themed GRIMM software security outfit by Adam Nichols.

              He said that while the vulnerabilities “are in code that is not remotely accessible, so this isn’t like a remote exploit”.

    • Defence/Aggression

      • That time that Facebook made Turkey happy

        In early 2018, Turkey launched a military offensive against Kurdish minorities in the Afrin District of northern Syria, arresting hundreds of its own residents for criticizing the operation. To minimize dissent, the Turkish government also asked Facebook to block posts from the People’s Protection Units. This is a mostly Kurdish militia group, known as the YPG, that among other things published on its Facebook page graphic images, including photos of mortally wounded fighters, writing in one post “this is the way NATO ally Turkey secures its borders”…

        [...]

        Easy: keep the platform operational, to protect profits, before human rights: “Cutting off revenue from Turkey could harm Facebook financially, regulatory filings suggest.” Just like Twitter, banning Trump only when the block would benefit, not hurt the BOTTOM LINE.

        Many people were both shocked and surprised by the intensity of police aggression at a recent vigil for murdered London woman Sarah Everard.

        When I saw the disturbing photo of Patsy Stevenson being pinned to the ground by male police officers, only days after one of their colleagues had been arrested for Everard’s murder, the first thing that came to mind were scenes I had witnessed and photographed myself half way around the world in Australia.

        It is important to think about it from the viewpoint of the police. This is not what they sign up for. They are acting on orders that come from the highest level of Government.

        The set of photos published below come from an event in 1998. Smart phones didn’t exist back then and digital cameras had only begun to appear. Very few students carried any form of camera and police could act with impunity. By chance, I lived across the road and I was shooting on a traditional SLR with film in it.

        The former Premier is well known for his military service. From time to time, an officer needs to show the troops and the enemy who is really in charge, as Lieutenant General Morrison did in this viral video.

            Ever since institution of the post-grant review proceedings enacted under the Leahy-Smith America Invents Act were implemented by the U.S. Patent and Trademark Office (through the newly constituted Patent Trial and Appeal Board), parties (particularly patentees who lost patent rights thereby) have challenged the outcome on procedural, substantive, and constitutional grounds (see “Cuozzo Speed Technologies LLC v.

      • Copyrights

        • Book review: The Cambridge Handbook of Copyright Limitations and Exceptions

          This edited collection provides a stellar list of contributors, many of whom have been included in this Kats recent book review saga, such as Aplin and Bently, Emily Hudson and other leading authors, making this handbook the first to bring together comparative reflection of copyright limitations and exceptions.

          The book is presented in 22 chapters, organised into 5 parts, which reflect the 5 principle themes presented by the volume. This is something that immediately sets this handbook apart from many others that this Kat has had the pleasure of reading – whilst it is a handbook covering a range of ideas, there is clear narrative that makes you want to read it cover to cover, rather than what we more commonly do with handbooks, which is to take a more a la carte approach to chapters of interest.

          [...]

          This part consists of 4 chapters that explore the role of international law in facilitating the global development of limitations and exceptions. The section begins with a chapter by Tanya Aplin and Lionel Bently, summising their arguments set out in their book, recently reviewed, Global Mandatory Fair Use, which focuses on Article 10(1) of the Berne Convention.

          Chapter 4, by Reto M. Hilty and Valentina Moscon describes the International Instrument for Permitted Uses developed by the Max Planck Institute for Innovation and Competition. The destiny of this Instrument remains open, but the aspiration of the project is to influence international and national legislation. In chapter 5 Martin Senftleben analyses the Marrakesh Treaty and in chapter 6 considers international provisions made for limitations and exceptions under international agreements.

          [...]

          This final part, consists of only one chapter, which is a shame as such an interesting topic could have benefited from further perspectives. Nevertheless, David Nimmer takes on the Part and the Chapter by looking at security measures and the future of US fair use. Nimmer argues that the fourth fair use factor that courts consider, namely; “the effect of the use upon the potential market for or value of the copyrighted works”, premises copyright liability on predicting the future, which is further complicated by the development of technology.

And it’s hard to believe she had nothing better to do at the time (better than such nostalgia). As we noted last year: “The above tweet of a beach was posted [by Melinda Gates] on the date of the arrest/search of their employee, who was at their residence at the time.” He was arrested around the very same time this tweet was posted. As we wrote last year (based on detailed documents obtained from the police department): “This tweet was posted 2 hours and 40 minutes after the door was breached and incriminating evidence collected.” He was arrested later that morning at the mansion of Bill and Melinda Gates (the police records contain detailed timelines to confirm the chronology). Melinda’s first name was also in the CP 'stash'.
