      • Intel P-State Changes Could Improve iGPU-Bound Performance – Some Cases ~15%, ~43% Perf-Per-Watt

        We’ve known that Intel’s P-State Linux CPU frequency scaling driver in general can be a bit quirky and especially so when dealing with Intel integrated graphics where the iGPU and CPU share the same power envelope. This has been shown with examples like using the “powersave” governor to boost iGPU performance while discrete graphics owners are generally best off switching over to the “performance” governor. As the latest though on helping the iGPU front with P-State, there is a new patch series talking up big gains in performance and power efficiency.

        Francisco Jerez of Intel’s open-source driver team sent out a set of ten patches today working on GPU-bound efficiency improvements for the Intel P-State driver.

        • Zorin OS 15.2 Released with New Features, Download Here Directly

          There’s a clear trend of users moving from Windows and macOS to Linux distros lately. And this journey is fueled by the dissatisfaction and limited capabilities of those two giants. Linux distributions as ZorinOS are no less than Windows, and even giving more options to customize and better security. The developers of ZorinOS have released the new version 15.2, which has support for more hardware, improved security, etc as notables.

          Though Linux itself is cool, it’s hard for a normie or a beginner to handle the extensive platform initially. That’s when several Linux distributions as Ubuntu, Mint, ElementaryOS, ZorinOS, etc stepped in, making the journey of users from Windows and macOS to Linux smooth and interesting. With respect to the latest development of such distribution, ZorinOS has rolled out its new version named v15.2. This contained new features as below:

        • Sculpt OS 20.02 Released – Built Off Genode, Now Includes File Manager + Editor

          Sculpt OS is the general purpose operating system built off the Genode operating system framework. Out now is their version 20.02 update that tries to make the OS more approachable.

          Given they are trying to make Sculpt OS a general purpose OS, they determined their reliance on command-line utilities is a barrier for adoption. So with Sculpt OS 20.02 they have introduced a custom graphical file manager and text editor. They hope the file manager and editor will make it easier tweaking the system state while the CLI options remain available.

        • Sculpt OS release 20.02

          With the release of Sculpt version 20.02, we follow our roadmap’s mission to make Sculpt OS easier to approach. In particular, we identified the reliance on a command-line interface as a potential barrier of entry. As Sculpt OS is not a Unix-like system, it should not require any Unix know-how from the user. To relieve users from this burden, Sculpt 20.02 introduces a custom graphical file browser and editor that can be used for interactively inspecting and tweaking the state of the system. The traditional command-line interface is still present as a fallback for advanced tasks though. The updated manual goes into detail about the use of the new system.

Also, container images are delivered from Quay.io primarily, and most of them are mirrored to the Red Hat container registries such as registry.access.redhat.com and registry.redhat.io. This was done to speed up the rate at which we can deliver updates, and facilitate over-the-air updates. You might be wondering how we ensure the integrity of bits delivered via this new delivery mechanism, so we’re going to dive into that in this post.

        • Axel Beckert: Backup over Tor with BackupPC

          I have a Raspberry Pi at my parents home. They have internet access via some ISP using Carrier Grade NAT (CGN). Hence their home router is not reachable via IPv4 from the outside, they do have IPv6 and the devices can also be made accessible via IPv6 via the local router.
          Did that, was able to access my Raspberry Pi over IPv6 and SSH from the outside. So doing backup of that Raspberry Pi with BackupPC from the outside was a walk in the park.

          Unfortunately the IPv6 prefix seems to change occasionally and the router only allows to configure explicit IPv6 addresses in firewall rules — so after a prefix change the configured rules no more match the devices IPv6 addresses. Meh.

      • Canonical/Ubuntu Family

        • On Boxing, Tabletop Exercises and Threat Models

          At Canonical we have recently performed a series of cyber tabletop exercises (TTX). A TTX is an information security preparedness drill where a cyber incident scenario is played out to improve your tactics, techniques and procedures (TTPs). When performing a TTX it is important to use the same amount of staff and effort as though a real incident were occuring. This helps to uncover deficiencies in your TTPs and address those issues before a real event occurs. Being as efficient as possible is critical during incident response because as time passes data that can help determine root cause is lost and the attacker may still be causing harm to the environment.

          This past month we performed two TTXs with different groups within Canonical. This type of exercise requires support from the top down, you will be interrupting work for up to a day and it is imperative that the management of each team is behind this effort. At Canonical security is in our DNA and this exercise was performed with full support of everyone within the company.

        One of the primary contributions of the open source community to the world is a system that allows random people from around the world to work together to solve complex problems, so it is no surprise that Collabora has been from the get-go a geographically distributed company. Our consultancy team of Open Source professionals is distributed across 2 offices – Cambridge, UK and Montreal, Canada – and remote based in more than 30 different countries around the globe.

        Here at Collabora, we trust our people to work remotely, we give them full responsibility for their output, and we believe it helps create an even stronger internal culture and comes with some other positives.

      • Server

        • Virtualise everything!

          his issue Jonni has been getting very angry at me for conflating the terms emulate and virtualise, don’t even get him started on containerise. Largely I hadn’t clocked that virtualise only includes systems running on the same hardware platform. Surely, that’s an easy enough mistake to make with the x86 platform being so dominant, it’s the main thing you are going to virtualise!

          This x86 world is changing though; sure for Linux Format readers x86 is going to remain the primary desktop platform. But there’s a good chance Arm plays as much a roll in your life, be that in the Raspberry Pi, your smartphone, tablet or smart TV.

          In big business Amazon is already running its own design of Arm-based server processor, Apple is posturing to launch an Arm-based consumer-level processor for laptops, while Microsoft is already peddling Arm-builds of Windows. You can see the world is changing. If slowly.

            We use Gravit Designer on the daily as our go-to vector editing and design tool but for a long time, Inkscape was always in the old tool bag. Problem was, using Inkscape on Chrome OS in the past required Crouton and the unofficial path to dual-booting Linux on your Chromebook. With the advent of the Crostini Project and Linux apps support, that has changed and for many, installing Inkscape free software on a Chromebook has been a game-changer for productivity. While we no longer use Inkscape, it is still an incredible vector editor and we recommend it for users who aren’t ready to make the jump to the pro version of Gravit that runs you $49.99/year.

There’s so much that you can do with Linux apps on Chrome OS but the Crostini project still has its limitations due to the nature of the technology. Running applications in containers requires some workarounds for certain things that are normally native on full Linux distributions.

            The latest release of Firefox features some login management improvements, the ability to add custom sites to the Facebook Container, better privacy for web voice and video calls, and better add-on management. See the release notes for more information.

          • Firefox 74 Released with DNS over HTTPS, Other Privacy Improvements

            The freshly accelerated Firefox release schedule see a new version of Firefox released every four weeks. The increased release rate allows the famous FOSS browser to bring new features to users faster.

            The headline change in Firefox 74 is the use of DNS over HTTPS by default for users in the USA.

            A privacy-minded feature, DNS over HTTPS encrypts all DNS requests made in Firefox 74 (requests which are normally done ‘in the open’). This helps prevent people snooping on internet traffic from discerning detail about the requests being made.

            Firefox 74 defaults to Cloudflare as the DNS resolver but users are able switch to NextDNS through the Preferences > Network Settings dialog.

          • Firefox 74 Begins Rolling Out With DNS-Over-HTTPS, Disabling TLS 1.0/1.1

            Firefox 74.0 is the release offering DNS-over-HTTPS support with Cloudflare as the default DNS resolver, TLS 1.0 and TLS 1.1 support is now disabled, sandbox security improvements, CSS text-underline-position support, implementing the JavaScript optional chaining operator, and many other developer improvements. The DNS over HTTPS is enabled by default for users in the United States with Firefox 74 while others can turn it on manually. While Cloudflare is the default DNS resolver, NextDNS can also be selected as another option. The roll-out began in late February and more details on Mozilla’s DoH work via this blog post.

          • Jiri Eischmann: Mozilla makes Firefox Beta available on Flathub

            I’m glad to see that Mozilla has made a significant process with offering Firefox as a flatpak. Having Firefox as a flatpak was one of our long-term goals.

            Three years ago we started a testing flatpak repo with Firefox Developer Edition and soon after that we added Firefox Nightly. For a long time it was the only source of Firefox for Flatpak out there. The user base grew into thousands, a level our hosting could barely deal with. Lately we haven’t had much time for its maintenance and at least the nightly builds were often broken.

            That’s why from the very beginning we worked with Mozilla to make official Firefox builds available as flatpaks. The effort was later on picked up by Endless.

            Now it brings first fruits, Mozilla is already shipping Firefox Beta in the beta channel on Flathub. You just need to enable it by installing this file: https://flathub.org/beta-repo/appstream/org.mozilla.firefox.flatpakref

            I think it may already be useful for Silverblue users who have relied on our testing repo if they didn’t want to use package overlay.

          • An Official Firefox Flatpak is on the Way

            With the Firefox 74 release out of the way Mozilla developers now turning their attention towards Firefox 75, scheduled for release in the early part of April.

            While Firefox 75 will (obviously) ship with new features, key changes and a dollop of developer-related improvements it will be notable for another reason:

            It’s looking like Firefox 75 will be the first version of the famed web browser to be released as a Flatpak app on the Flathub app store.

          • Hacks.Mozilla.Org: Security means more with Firefox 74

The most significant new features we’ve got for you this time are security enhancements: Feature Policy, the Cross-Origin-Resource-Policy header, and removal of TLS 1.0/1.1 support. We’ve also got some new CSS text property features, the JS optional chaining operator, and additional 2D canvas text metric features, along with the usual wealth of DevTools enhancements and bug fixes.

          • Support for extension sideloading has ended

            Today marks the release of Firefox 74 and as we announced last fall, developers will no longer be able to install extensions without the user taking an action. This installation method was typically done through application installers, and is commonly referred to as “sideloading.”

            If you are the developer of an extension that installs itself via sideloading, please make sure that your users can install the extension from your own website or from addons.mozilla.org (AMO).

        • Announcing Open Badges for LibreOffice contributors!

          LibreOffice is made by volunteers and certified developers across the globe, and today we’re announcing a new system to credit their work and show appreciation: Open Badges. So what are they?

          In a nutshell, Open Badges are PNG images that are awarded to contributors for reaching a certain threshold – such as a number of commits to the codebase, or answering questions on Ask LibreOffice. But these images are something special: they contain metadata describing the contributor’s work, which can be verified using an external service. Open Badges are used by other free software projects, such as Fedora.

          We at The Document Foundation – the non-profit entity behind LibreOffice – will start issuing customised badges to contributors, who can then proudly display them on websites or social media. And because of the embedded metadata, contributors can use the badges as proof of their work. If you’ve been a long-time contributor to LibreOffice and are in the job market, use your badge to highlight your involvement in a large open source project!

          Padded numbering is a style where you insert 0 characters in front of an otherwise normal (Arabic) numbering, making sure that the result always has at least N characters. Up to now, you had to number your content manually to have this effect, while Word supports this feature.

          OOXML supports padding up to 2, 3, 4 and 5 characters. Padding up to 2 characters is the older feature, supported in DOC and RTF as well, so I focused on that piece.

        • Expert Brochure to Modernise Public Digital Infrastructure with Public Code – Translated Versions Online

          What is Free Software? How does it contribute to digital sovereignty, security and transparency of state digital infrastructure? Which steps can public administrations take? These and more questions are answered in our publication “Public Money Public Code – Modernising Public Infrastructure with Free Software”. After the successful release of the English version of our brochure we translated it into three more languages: German, Czech and Brazilian Portuguese.

          The recent debates about digital sovereignty show that the desire for self-determined government action in the field of digitisation is immense. Digital services offered and used by our public administrations are the critical infrastructure of 21st century. In order to establish trustworthy systems, public bodies must ensure they have full control over the software and the computer systems at the core of our state digital infrastructure. We need software that helps public administrations regain sovereignty over their critical digital infrastructure, allowing them to become and remain independent from a handful of companies.

          The brochure summarises the FSFE’s long-term expertise with additional knowledge from leading experts in various ICT areas. It helps readers understand Free Software and its benefits for a modern digital public infrastructure. Hot topics covered include the avoidance of vendor lock-in, improvement of IT security through openness, exploring different business models, handling of procurement issues, and learning from innovative approaches to smart cities.

          - Continued work on improving the Bash/CLI auto-completion for different sub-commands.

        • Perl / Raku

          • The Weekly Challenge #051

            I am really enjoying the weekly challenges, specially doing in Raku. The point of blogging is also about sharing my fight with Raku. I hardly write anything about my Perl solution as I don’t see anything new to talk about. Having said that, I still go for Perl first as it is my first love and will remain so rest of my life. Even today, my brain is so tuned to Perl, every ideas come in form and shape of Perl only. I started contributing in the Week #46. I could only find time to do Perl solutions in the Week #46. The following Week #47 was the same as I didn’t get to do Raku. It was the Week #48 when I managed to find time to do both Perl and Raku for the first time. Ever since I have been able to contribute every week in both languages. I would give the credit to the fellow Team PWC member, Ryan Thompson, for helping me with the Perl and Raku reviews.

          • Zato services as containers for Python functions and methods

            Acting as containers for enterprise APIs, Zato services are able to invoke each other to form higher-level processes and message flows. What if a service needs to invoke a hot-deployable Python function or method, though? Read on to learn details of how to accomplish it.

            In this tutorial, we will learn about polymorphism, different types of polymorphism, and how we can implement them in Python with the help of examples.

          • Defining Main Functions in Python

            Many programming languages have a special function that is automatically executed when an operating system starts to run a program. This function is usually called main() and must have a specific return type and arguments according to the language standard. On the other hand, the Python interpreter executes scripts starting at the top of the file, and there is no specific function that Python automatically executes.

            Nevertheless, having a defined starting point for the execution of a program is useful for understanding how a program works. Python programmers have come up with several conventions to define this starting point.

            Lists are a fundamental data type in the Python programming language. A list is a mutable sequence that is typically a collection of homogeneous items. Mutable means that you can change a list after its creation. You will frequently see lists that contain other lists. These are known as nested lists. You will also see lists that contain all manner of other data types, such as dictionaries, tuples or objects.

          • Life tables

            I know I’ll die, sooner or later, but how many years do I have left?

            There’s no answer to that question for me or for anyone else interested in their future, because the future is unknowable. That hasn’t stopped demographers and actuaries from calculating life expectancies in years and sometimes making news with their calculations.

            Here in Australia the Government Actuary produces Life Tables every 5 years. The tables are based on enumeration. How many 60-year-old women were there at the last Census? How many 60-y-o women died around the Census time? From those numbers (and others) the Actuary can calculate a current likelihood of dying and an expected number of years before death for 60-y-o women.

            Tallying population and death totals isn’t straightforward and adjustments are made to both the current male and female populations at each age, and to the death numbers. The population figures in the latest Life Tables were adjusted from the 2016 Census, and the death figures cover the 3 years 2015-2017.

        Intel has added bare-metal oneAPI support to its open-source Graphics Compute Runtime for OpenCL and oneAPI, according to a Phoronix report on Monday. This brings oneAPI Level Zero to Linux.

        Intel’s bare-metal specification for oneAPI is known as Level Zero and provides the lowest-level access to hardware, such as accelerators. Intel has now brought initial support for Level Zero to its Graphics Compute Runtime for OpenCL and oneAPI, as evidenced by a commit on GitHub.

      • OMEMO Specification Sprint

        The past weekend some members of the XMPP community gathered in Düsseldorf to work on the next iteration of the OMEMO Encryption Specification. All of us agree that the result – version 0.4 of XEP-0384 – is a huge step forward and better than ever!

        On Saturday morning we met up at the Chaosdorf, a local Hacker Space who’s members kindly hosted the sprint. Huge thanks to them for having us!

        Prior to the sprint we had collected a list of bullet points of topics we wanted to discuss. Among the more urging topics was proper specification of OMEMO for group chats, support for encrypting extension elements other than the body, as well as clarification on how to implement OMEMO without having to use libsignal. While the latter was technically already possible having a clear written documentation on how to do it is very important.

      • staying home

        I was to fly to Boston tomorrow evening, but I’m staying home instead. Just a few days ago, I was thinking all the fear around Covid-19 was silly, but then I caught a very mild cold and, wondering whether that could get me quarantined, sent back home, or barred from travelling, I started looking into the matter, and what I learned changed my mind.

        I used to think I was reasonably healthy, and though I invariably catch a bug at conferences abroad, for sleepless nights in tight plane seats and long exposure to unknown pathogens, I’m likely able to survive Covid-19 even if I came across it, which was extremely unlikely to begin with. It’s not much more than a flu, after all, right?

        Well… It’s not so simple. What happens if everyone reasons this way and carries life on as usual? The virus spreads very fast, healthcare units get overloaded, and even people with very treatable diseases fail to get treatment and die.

        Avoiding unnecessary physical contact slows down the propagation. In extreme cases, this might even get a virus to die off. Even if we don’t go that far, the more we slow it down, the more time we buy to develop treatments and vaccines, and the less we overload healthcare units so that people who need treatment are more likely to get it.

      • Stephen Michael Kellat: Following The Planning P

        Why bring that up? The big reason is to mention the need for backup plans and continuity plans. With COVID-19 concerns in play within the continental United States, the Windows Subsystem for Linux conference had to switch from being an in-person event to a virtual event. After my broadband decided to die on me I decided to follow up on guidance from the state’s election authorities to get early voting out of the way as reported by the Cleveland Plain Dealer. My account on Instapaper has been full of closure listings in the local area such as Kent State University stopping classes on all campuses including the local commuter campus in Ashtabula. Many people and institutions are having to improvise, adapt, and overcome.

        For the individual developer, though, there should be some consideration about COVID-19. Is your code maintained in a way that nobody else could access it if you were incapacitated? Do you have a “trusted person” who has delegated access if you become incapacitated so automated systems can continue to function? Is your code clean and commented sufficiently so that somebody could take over maintaining it if, heaven forfend, you are out of commission for an extended period of time?

        These are all good business practices. The COVID-19 situation merely brings them into sharp focus as being essential business practices. If you haven’t implemented them already there is no time like the present.

                Project Owl is a cloud-based analytics tool that helps facilitate Organization, Whereabouts, and Logistics (Owl, for short) for disaster response. Our team developed a mesh network of Internet of Things (IoT) devices called “DuckLinks” that can be deployed or activated in disaster areas to quickly re-establish connectivity and improve communication between first responders and civilians in need.

                In 2018, we won the inaugural Call for Code Global Challenge. Our idea rose to the top from over 100,000 participants from 156 nations and we won the opportunity to work with IBM’s Code and Response initiative with The Linux Foundation, to help us build, fortify, test and launch our solution to help communities in need.

        • Security

          • Meltdown The Sequel strikes Intel chips – and full mitigation against data-meddling LVI flaw will slash performance

            Computer security researchers involved in the discovery of the Meltdown and Spectre vulnerabilities affecting many modern processors have developed a related attack technique called Load Value Injection (LVI).

            The attack relies on microarchitectural data leakage to inject and execute malicious code in a way that breaks the confidentiality of modern Intel systems.

            Chipzilla’s processors, already weighed down by defenses deployed against side-channel attacks over the past two years, could get slower still if they try to thwart this latest vulnerability: prototype compiler changes, for full mitigation, have produced performance reductions ranging from 2x to 19x.

          • LVI Attack Hits Intel SGX – Defeats Existing Mitigations, More Performance Hits

            Load Value Injection (LVI) is being disclosed today as a new class of transient-execution attacks and the researchers claim can defeat all existing mitigations around Meltdown, Foreshadow, Zombieload, RIDL and Fallout. The researchers say LVI can affect virtually any access to memory and compiler-based mitigations can be expensive.

            LVI combines Spectre-style code gadgets with Meltdown-type illegal data flows to bypass existing defenses and allow injecting data into a victim’s transient execution. LVI was discovered in April of 2019 while today the researchers and Intel are making a coordinated disclosure. The initial discovery was made again by university researchers but Bitdefender ended up also discovering the same vulnerability.

          • Say hello to your new best friend ‘LVI’ – another security flaw in CPUs for Intel

            Oh hell. This comes shortly after Intel had another one announced that was ‘unfixable’, plus one for AMD too and now this all in the space of a month. Rough time right now, for Intel specifically on this one.

    • Finance

      • Should working while you commute count as paid time?

        Few people look forward to their commute, but Albane Bochatay, 30, has it easier than most. With Switzerland’s snow-capped mountains and Lake Geneva as a backdrop and an almost guaranteed seat, her one-hour train journey one-way is decidedly more relaxing than a packed London Underground train. And most importantly, she gets paid for it.

        After moving from Bern, the centre of government, to the southwestern city of Lausanne, Bochatay, a research associate for Swiss union Transfair, now works at a regional office near her home two days a week and commutes to the headquarters in Bern the other three. And thanks to Switzerland’s well-equipped and uncrowded trains, her boss was happy for her to start her workday on the journey in.

        “I can answer my mails, I can read some papers, I can also write some minutes, so I can actually do a lot of things on the train,” she says. “And now I can be home at six in the evening and I can do some sport or see some friends. So it’s a good balance.”
