  • Videos and slides of Bootlin presentations at FOSDEM

    The videos from Bootlin’s presentations earlier this month at FOSDEM 2021 are now publicly available. Once again, FOSDEM was a busy event, even if it was online for once. As in most technical conferences, Bootlin engineers volunteered to share their experience and research by giving two talks.

  • Intel's Simple Firmware Interface Being Killed Off With Linux 5.12 - Phoronix

    Intel's "Simple Firmware Interface" that dates back to the company's early Atom-powered mobile days is being eliminated with the in-development Linux 5.12 kernel.

    More than one decade ago with the Intel Moorestown platform, Simple Firmware Interface (SFI) was envisioned as a solution for lightweight devices in place of a complete ACPI implementation. Intel hasn't employed the Simple Firmware Interface as part of their platform design in years while ACPI is alive and well. Last year Intel engineers marked SFI as "obsolete" within the Linux kernel and confirmed Intel had no plans of resurrecting the Simple Firmware Interface.

  • VFIO Gets Batched Page Pinning For An Easy Performance Improvement With Linux 5.12 - Phoronix

    The VFIO changes to the Linux 5.12 kernel include an optimization worth mentioning.

    The VFIO driver work for Linux 5.12 isn't too significant but the batched page pinning will be of interest to some. Up to now the VFIO kernel code has relied on pinning one 4K page at a time. That major efficiency bottleneck has been addressed with the batched page pinning to handle batches of 512 at a time.

New changes to Twitter make it even worse for free software users

Filed under
GNU
Web

There are many complicated debates happening right now around Twitter and its role in public discourse. These discussions are important, but we also shouldn't forget a very basic and clear principle -- whatever its policies are about who can and can't post or how, it's of fundamental importance that Twitter should not require users to run nonfree software in order to use the site.

Unfortunately, on December 15th, Twitter removed its "legacy" Web interface. As opposed to its much larger and more complex default Web client, the legacy interface did not use proprietary JavaScript (or any JavaScript).

Previously, the Free Software Foundation (FSF) could tolerate the use of Twitter because of this legacy interface. While it was active, we referred free software advocates to it, or to third-party free software applications. Twitter's removing access to this interface means that users are forced to use the site's nonfree JavaScript if they don't have a dedicated desktop or mobile client, preventing freedom-respecting browsers like GNU IceCat from posting to the service.

But why use Twitter in the first place, if we know that it has these issues? As any charity can attest, engaging users on social media is one of the chief ways of getting their message across. The same is true for software freedom. We need to be talking about free software in places where everyone is not already a committed free software supporter -- we won't be successful if we are only in our own echo chamber, or preaching to the choir. It's important for us as activists to be reaching the people on these platforms, even if we have some reservations about using them ourselves. Twitter has its share of issues, but until we're able to drive enough users to the software freedom movement to where we can rely solely on word of mouth, we need to include them in our messaging strategy. We are, however, careful to make sure that you don't have to follow the FSF on Twitter in order to receive news or updates. Everything we publish is also posted on platforms based on free software principles, including Mastodon and GNU social.

Trisquel 9.0 review

Filed under
Reviews

The world is full of people shouting and clamoring for the latest thing (and the last review pages because we go to press today – Ed). So it’s always reassuring to discover places where things still move slowly.

Nowhere is this more true than Trisquel, the freedom (as in speechdom)-loving, Ubuntu-based distro endorsed by the Free Software Foundation.

Trisquel used to push out one release a year (based on the corresponding Ubuntu LTS release), but it’s been over 18 months since the previous release. And that one took over three years to come into fruition. This new release is based on Ubuntu 18.04, the second-to-last LTS release, which is supported until 2023.

[...]

With this release Trisquel moves from Xfce to the MATE desktop, so if you long for those Gnome 2 vibes then this might be for you. ISOs are getting bigger and Trisquel’s weighs in at 2.6GB. A 1.2GB mini-image is available that runs LXDE – ideal for older machines.

There’s also Triskel, a KDE spin, and Trisquel Sugar Toast which is an educational release. Oh and there’s a tiny Net Install image too if you want to build a minimal but freedom-loving OS from the ground up.

Ubuntu

We really enjoyed the last Ubuntu release, and indeed the slew of Ubuntu-derivatives (such as Mint and Pop!_OS) that have been rebased on 20.04. We’re still waiting patiently for elementary OS 6 though...

For those unfamiliar with Ubuntu’s release cycle, this is the first of three interim, short-term release (STR) versions that Canonical and the community will use to shape the next LTS (long-term support) release in 2022. If you’re looking for stability and would rather nothing broke, we’d strongly advise you to stick with the LTS.

FossaPup64 9.5 review

Filed under
Reviews
Ubuntu

Puppy’s Ubuntu-based release has had a major update and is now based on Ubuntu 20.04 Focal Fossa. This means that FossaPup64 9.5 (which also goes by the much easier nomenclature, Puppy Linux 9.5) is binary compatible with the latest Ubuntu LTS release and can pull applications from its repositories without any issues.

This release is the fourth official release of an Ubuntu-based 64-bit Puppy. Like all Puppy distros, FossaPup64 is built using the Woof-CE build system that’s designed to assemble Puppy variants from the binary packages of any other distro.

A key feature of the official Puppy releases is that they’re modular. You can easily swap out components including the kernel and various programs to create a streamlined Puppy.

  • Learning more about our users

    At the Tor Project we practice user-centered design. This means we put our users at the heart of our development process, making a conscious effort to understand the contexts in which people use our tools and paying particular attention to the bumps they encounter along the way.

    Many digital product companies rely heavily on data gathered from invasive tracking scripts to better understand their users’ behavior, further fueling the surveillance economy. However that’s not how we do things at Tor – instead, we aim to conduct research that respects the basic principles of privacy and consent.

  • Keeping platforms open

    My previous article, Whatsapp and the domestication of users, got more attention than I was expecting. Some responses gave me a lot to think about,1 especially regarding actions we can take. I suggest reading that article first; it explained what “user domestication” is and why it’s a problem. It enumerated three countermeasures: FOSS, simplicity, and open platforms.

    Hard problems, by definition, lack easy solutions. Simply choosing (or creating) a platform that avoids user domestication isn’t enough if that platform can change. The price of freedom is eternal vigilance; in addition to settling on the right platform, we must ensure that it honors its users in both the present and the future. Keeping a platform FOSS and simple is more straightforward2 than keeping a platform “open”.

    How do we keep an open platform from becoming a closed platform in the future?

  • 6 Top Data Analysis Tools for Big Data

    Big Data is an all-inclusive term that refers to data sets so large and complex that they need to be processed by specially designed hardware and software tools. The data sets are typically of the order of tera or exabytes in size. These data sets are created from a diverse range of sources: sensors that gather climate information, publicly available information such as magazines, newspapers, articles. Other examples where big data is generated include purchase transaction records, web logs, medical records, military surveillance, video and image archives, and large-scale e-commerce.

    There is a heightened interest in Big Data and Big Data analysis and the implications they have for businesses. Big Data analysis is the process of examining huge quantities of data to find patterns, correlations, and other useful information that can help firms become more responsive to change, and to make better informed decisions.

    Big Data analysis can be performed with data mining software. However, the unstructured data sources used for big data analysis are not necessarily suitable for investigation by traditional data mining software.

  • 50 Years of Pascal

    Pascal was easy to teach, and it covered a wide spectrum of applications, which was a significant advantage over Algol, Fortran, and Cobol. The Pascal System was efficient, compact, and easy to use. The language was strongly influenced by the new discipline of structured programming, advocated primarily by E.W. Dijkstra to avert the threatening software crisis (1968).

  • How to use Django Serializers – Linux Hint

    Serializer is used in Django to convert the model instances or querysets into python supported data types that can be easily rendered into JSON, XML, or other formats. The deserialization can also be done by serializers to get back the original data from the serialized data. This feature is available in Django REST Framework. So, the users have to install this framework to use the serializers. Any webpage of the website may contain HTML, CSS, and data from the database tables. But the API does not understand these types of content, and it can understand the raw data only, that is, JSON data. How the serializers can be used to convert the model instance into JSON format has shown in this tutorial.

  • How to use queryset in django – Linux Hint

    Most of the web applications are implemented with the database now. queryset is used in the Django application to retrieve records by filtering or slicing or ordering the database table without changing the original data. The model used Django to create the table in the database. So, the knowledge of using the model in Django is necessary to understand the use of queryset. The main function of the queryset is to iterate the records of database tables by converting them into SQL queries. It can be used from the python command line or by writing the python script to display the browser’s output. The uses of queryset for retrieving data from a database table in different ways have been explained in this tutorial.

  • How often should I rotate my ssh keys?

    My story for today is about ssh and how even public keys, while much better than simple passwords, are still not a perfect solution.

    The danger is credential theft, which is a fancy way of saying “someone stole your private keys.” Back in the 1990s, that problem was pretty far from our minds; Windows 98 didn’t even have the concept of a separate administrator account, never mind the idea of app sandboxing or the inkling that someone might intentionally want to load malware onto your computer and encrypt all your files for ransomware. Those were the days when some people thought ActiveX controls (essentially loading .exe files from web sites) might be a good idea. Actually, maybe even a great idea as long as there was an “are you sure?” dialog box first.

  • Ubuntu Aims For Higher Quality LTS Point Releases - Phoronix

    New restrictions will be in place beginning with Ubuntu 20.04.3 LTS this summer to try to enforce better quality releases with less regressions by enforcing better quality control.

    The change beginning with Ubuntu 20.04.3 LTS will require that stable release update (SRU) procedures are followed even for release blockers. This will require that every fix follows the same verification, regression analysis, and aging period process. The tighter quality controls will likely lead to slips in release targets if bugs are found in the release candidates for new point releases, as it will first need to go through the verification and aging process.

  • AMD Radeon "Aldebaran" GPU Support Published For Next-Gen CDNA - Phoronix

    Last week I noted "GFX90A" appearing in the AMD LLVM back-end and now the AMDGPU Linux kernel driver patches have appeared for "Aldebaran" that appear to be the codename for the next-generation CDNA part making use of GFX90A.

    A set of 159 patches were just posted today for the Radeon Aldebaran enablement. The kernel patches indeed confirm this being GFX9 / GFX90A, putting it as CDNA rather than Navi/RDNA as is the case with GFX10. Aldebaran is likely the successor to the Radeon Instinct MI100. Other takeaways and signs of Aldebaran being the Arcturus (MI100) successor include XGMI support, among other features aligning it for HPC like RAS and watchdog support.

    Most exciting with GFX90A that we have seen is it will support full-rate FP64. Aldebaran has VCN 2.6 video encode capabilities.

We have not been provided with any review sample and as such no Linux benchmarks today -- at least there are the RTX 3060 Ti Linux benchmarks for those interested.

  • Nvidia GeForce RTX 3060 goes out today, new Linux driver released

    For the release of the hardware, it's probably going to be another "paper launch" as we fully expect stock of the GeForce RTX 3060 from NVIDIA to sell out pretty darn quickly just like all the other releases have done so. Thanks in part to high demand and scalpers continuing to buy up as much as they can to sell on for a profit - amongst other things. However, NVIDIA are trying to cut down on crypto miners using standard GPUs by limiting the hash rate of the cards through a mix of a "secure handshake between the driver, the RTX 3060 silicon, and the BIOS (firmware) that prevents removal of the hash rate limiter" (source) plus dedicated cards for miners. So hopefully in future we will see more cards available for standard consumers and gamers.

However, I believe that a well-written self-review can help you accelerate your career, whether your goal is a raise, a promotion, or merely some well-deserved recognition for your efforts. In this article, I’ll discuss my approach to performance reviews. While there is no one-size-fits-all strategy, this approach has served me well through several organizations and positions.

  • Red Hat OpenShift drives a strong 5G open RAN ecosystem

    As the telecommunications industry ramps up its evolution towards cloud-native architectures and containers, communications service providers (CSPs) are working to scale their networks to support increased demand. In this effort, open radio access network (RAN) solutions offer standardized disaggregation of the RAN, decoupling hardware and software, to give CSPs more freedom of choice. Many organizations are looking to implement a container platform like Red Hat OpenShift that is ready to take on the intensive demands of this evolution for their RAN and for new 5G use cases, such as network slicing, IoT and industrial IoT. Moving to a cloud-native platform creates the opportunity for many of them to work with new suppliers, boost innovation and better differentiate using new operating models.

    Red Hat is excited to play a key role in this transformation. Last year, we shared the news of our expanded collaboration with Altiostar to develop an infrastructure and workload automation framework for a container-based RAN reference architecture that allows a consistent approach to a disaggregated RAN for both our customer and partner ecosystem. We’re now excited to build on this momentum by extending our architecture in collaboration with Mavenir, to transform mobile network infrastructures.

  • Debuginfod project update: New clients and metrics - Red Hat Developer

    It’s been about a year since our last update about debuginfod, an HTTP file server that serves debugging resources to debugger-like tools. Since then, we’ve been busy integrating clients across a range of developer tools and improving the server’s available metrics. This article covers the features and improvements we’ve added to debuginfod since our last update.

    [...]

    Debuginfod is a part of the elfutils project. Tools that already use elfutils to find or analyze debugging resources automatically inherit debuginfod support. Tools like Systemtap, Libabigail, and dwgrep all inherit debuginfod this way. In Systemtap, for example, debuginfod offers new ways to specify which processes to probe. Previously, if you wanted to explore a running user process, you would have to provide either a process identifier (PID) or the executable path. With debuginfod, Systemtap can probe processes according to build-id, as well. So, it is possible to investigate specific versions of a binary independently from the location of the corresponding executable file.

    Debuginfod includes a client library (libdebuginfod) that lets other tools easily query debuginfod servers for source files, executables, and of course, debuginfo—generally, DWARF (debugging with attributed record format) debuginfo. Since last year, a variety of developer tools have integrated debuginfod clients. As of version 2.34, Binutils includes debuginfod support for its components that use separate debuginfo (readelf and objdump). Starting in version 9.03, the Annobin project contains debuginfod support for fetching separate debuginfo files, and support for Dyninst is planned in version 10.3.

KVM stands for Kernel Virtual Machine, where QEMU is an emulator that can also be used as a virtualizer with the help of KVM to provide a native speed by accessing Intel VT-x or AMD V technology of modern processors.

    KVM is a virtualization module that can easily be installed in any Linux kernel to allow it to function as a type 2 hypervisor.

    Thus, the installation of KVM becomes a lot easier, we only need a Linux-based system such as Ubuntu and a processor with intel-v / VT-x or AMD-v support. All new processors have this instruction set extension. Only the small processors, such as the Atom from Intel, or very old processors may lack this feature.

Games: Valve, Skullgirls, Top 7 Predictions for Linux Gaming in 2021, and New Record

  • Valve launch a Beta for Remote Play Together - Invite Anyone, no Steam account needed

    The invites work through the Steam Link app, which has one big caveat at the moment: Valve doesn't currently support a normal Linux desktop with it.

  • Hadean Tactics, a realtime auto-battler with deck building, launches today | GamingOnLinux

    What happens when Slay the Spire has a baby with DOTA Underlords? We're about to find out in Hadean Tactics. Ready to launch later today into Early Access, Hadean Tactics is a fascinating mash up of roguelite auto-battler, and deck builder. You take on the role of the Inquisitor, aiming to vanquish the six wings of Hell.

    Core gameplay follows the DOTA Underlords mechanic of placing your units on a grid-based battlefield, then watching them choose their targets and pound away, dealing damage according to their DPS (damage per second) stat, and special abilities which are powered by mana. All very familiar so far.

    What sets Hadean Tactics out from that setting is that the frenetic action is paused every 7 seconds and you’re dropped into a Slay the Spire mechanic. You’re issued with 3 energy and five cards are drawn from your deck. Most cards cost at least one energy to use, and how you play them will affect the ongoing battle when you “end turn”, having played your cards.

  • Gloomy and tough arena shooter Devil Daggers gets a 5 year anniversary update | GamingOnLinux

    Devil Daggers is really something else and I fear for my free time again, as the recent 5 year anniversary update is a great reminder that it begs to be played.

    It's a high-score chasing arena shooter, inspired by 1990s FPS and arcade games. You get dumped into a small and dark arena to face off against never-ending waves of demons armed with only your magic dagger and quick movement. You just fight to survive as long as you can and see if you can beat your friends and the world on the leaderboards.

  • Linux support for Skullgirls to continue, everyone upgraded to Skullgirls 2nd Encore free | GamingOnLinux

    Quite a bit of ground to cover on the popular fighting game Skullgirls, now that the dust has settled with Lab Zero Games imploding and Hidden Variable Studios / Autumn Games taking back control.

    Firstly, there's no longer a 2nd Encore Upgrade. Instead, everyone has been upgraded to that edition with all previous DLC being bundled into the main game as a free upgrade. Why?

  • Valheim still growing with 4 million sales, hits top 5 of most played games on Steam ever | GamingOnLinux

    Valheim Valheim Valheim, it's all we've been hearing lately. We're guilty of it, other websites and content creators have covered it a lot and so expectedly it's hit new highs again.

Not only that, Valheim managed to hit over 500,000 players online at the same time on February 21, which means more people were in game than there were actual Vikings in human history. A more modern detail is that it makes Valheim now on the top 5 of most played games on Steam — ever.

    Other fun details include the game being played for "a combined total of 10,000 years" and it continues to climb the Steam Top 250 leaderboard for the best reviewed games of all time and they've hit over 92,000 reviews on Steam.

  • What is Automation and Configuration Management with CHEF – Part 1

    Configuration Management is the key focus point of DevOps practice. In the Software development cycle, all the servers should be software-configured and maintained well in such a way that they should not make any break in the development cycle. Bad configuration Management can make system outages, leaks, and data breaches. Using Configuration Management tools is about facilitating accuracy, efficiency, and speed in the DevOps-driven environment. There are two models of configuration Management tools – PUSH-based & PULL-based. In the PUSH-based, the Master server pushes the configuration code to the servers wherein PULL-based individual servers contact the Master for getting configuration code. PUPPET and CHEF are widely used PULL-based models, ANSIBLE is a popular PUSH-based model. In this article, we will see about CHEF.

What is GNU/Linux Copypasta?

I’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX. Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project. There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux! Read more

Ben Widawsky: Framebuffer Modifiers Part 1

In a now pretty well established tradition on my part, I am posting on things I no longer work on! I gave a talk on modifiers at XDC 2017 and Linux Plumbers 2017 audio only. It was always my goal to have a blog post accompany the work. Relatively shortly after the talks, I ended up leaving graphics and so it dropped on the priority list. I'm splitting this up into two posts. This post will go over the problem, and solutions. The next post will go over the implementation details. Read more

Linux Lite 5.4 Will Be Based on Ubuntu 20.04.2 LTS, Release Candidate Ready for Testing

Linux Lite is a user-friendly distro that aims to bring more ex-Windows users to the Linux and Open Source ecosystem. The new release of this Ubuntu derived distribution, Linux Lite 5.4, will be based on Canonical’s recently released Ubuntu 20.04.2 LTS (Focal Fossa) operating system. But Linux Lite 5.4 will ship with the long-term supported Linux 5.4 LTS kernel instead of the much newer Linux kernel 5.8 from Ubuntu 20.04.2 LTS. However, users will be able to install any other kernel they want up to the recently released Linux kernel 5.11 from the software repositories with just two commands. Read more
