  • Mesa's Classic Drivers Have Been Retired - Affecting ATI R100/R200 & More - Phoronix

    The day has finally come that Mesa's classic OpenGL drivers (non-Gallium3D) have been cleared out of the code-base as part of their modernization effort for mainline.

    After a half-year pending, the "Delete Mesa Classic" merge request was honored today in eliminating the Mesa "classic" OpenGL drivers from the code-base. The drivers will still be maintained in an "Amber" branch, but considering how little focus these drivers have been receiving by upstream Mesa developers currently, don't expect much (or, if any) real changes moving ahead.

  • Steam support for Chromebooks could surface this week

    After months and months and even more months of waiting, it appears that we may finally get our first look at native Steam gaming on Chrome OS in the very near future. Affectionately known as project ‘Borealis’, the containerized version of Steam has been in the works for nearly two years and it was initially thought that Google was targeting mid to late 2022 for a release. With Chrome OS 96 just rolling out and the next iteration of Google’s desktop operating system not due until January of 2022, it’s fairly clear that this target was missed but that’s okay. I’d rather see a fully baked product released than a buggy piece of software that sours users to Chrome OS.
    Anyway, in its early development, I presumed that ‘Borealis’, a.k.a. Steam on Chrome OS, would simply be an optimized version of the Steam application that would install and run inside the current Linux container. Over time, we learned that Google was actually creating an entirely new container designed specifically to house Borealis and that it should run independently from the Debian container currently available in Stable Chrome OS. This makes more sense as Google can retain control of the Borealis container and keep it neat and clean for running Steam. Presumably, users will never actually interact with the container like you can with the Linux terminal.

  • Add Second Disk to Existing TrueNAS Pool in Mirror Configuration (RAID1)

    We are using the TrueNAS homelab server that we created some time ago to provide a share storage solution for Kubernetes.

    When we built the TrueNAS server, we went for the most basic and least expensive ZFS pool with a single disk. It worked well but did not provide any redundancy. While we didn’t store any important data in Kubernetes at the time, we do now. We’ve got ElasticSearch logs, WordPress MySQL databases, Prometheus metrics etc.

    We’ve purchased a second hard drive that is of the same size, and we want to use it as a mirror disk, also known as RAID1, to ensure that no data loss occurs in a case of a single drive failure.

    A few months ago I was trying to compare two mortgage offers, and ended up writing a small mortgage calculator to help me. Both mortgages were fixed-term for the same time period (5 years). One of the mortgages had a lower rate than the other, but much higher arrangement fees.

    A broker recommended the mortgage with the higher rate but lower fee, on an affordability basis for the fixed term: over all, we would spend less money within the fixed term on that deal than the other. (I thought) this left one bit of information missing: what remaining balance would there be at the end of the term?

    “When you consider that, you see that there are data privacy and cybersecurity issues, ethical issues, and safety issues.”

    The volume of data that AI models can maintain is staggering. Without the proper safeguards and regulatory assurances, AI could pose risks to patient data security and privacy.

The view that Linux is a server operating system only is an outdated view. There are hundreds of Linux distributions designed specifically to be beneficial for the average desktop/laptop user, and it is perhaps time you consider switching to Linux from Windows.

When we talk about switching to Linux, we talk about using distributions like Ubuntu or Linux Mint instead of your Windows installation. Of course, you don’t have to get rid of Windows at the same day either; you can install Linux side by side with Windows if you wish, until you have finally made your mind about it.

  • Wake-Up Robot Does It Gently | Hackaday

    For hundreds of years, people have fallen asleep while reading in bed late at night. These days it’s worse, what with us taking phones to the face instead when we start to nod off. At least they don’t have pointy corners like books. While you may not want to share your bedroom with a robot, this wake-up robot by [Norbert Zare] may be just the thing to keep you awake.

    Here’s how it works: a Raspberry Pi camera on a servo wanders around at eye level, and the Pi it’s attached to uses OpenCV to determine whether those eyes are open or starting to get heavy. The bot can also speak — it uses eSpeak to introduce itself as a bot designed not to let you sleep. Then when it catches you snoozing, it repeatedly intones ‘wake up’ in a bored British accent.

  • Is It Finally Time For Christmas Decorations? | Hackaday

    [Arnov] is trying to get into the holiday spirit and is doing so the way he knows how. He was thinking of some cool decorations for his Christmas tree and decided the best decorations are the ones you make yourself, so he made his own blinky Christmas tree ornament.

    The famed “blinky circuit” is certainly one that we are no strangers to here at Hackaday. Some of our readers will be very pleased to see that he did in fact use a 555 timer and not an Arduino. The 555 timer is wired to drive the clock pin of the CD4017 decade counter and the outputs of the decade counter are wired to the LEDs. The LEDs are lit up sequentially upon each low to high transition of the clock pulse though you may try getting creative with your LED wiring scheme to achieve different blinking effects.

  • Finally, A Use For Old Cellphones | Hackaday

    In what is now a three-year long search, I’ve finally found the perfect use for an old cellphone. And with it, the answer to a burning question: Why aren’t we hacking cellphones?

    First, the application. The Octo4a project lets you use an old Android phone as a 3D printer server, web interface, and even time-lapse camera to make those nice movies where the print seems to grow up out of nothing before your eyes. It’s the perfect application for an old phone, making use of the memory, WiFi, graphics capabilities, and even the touch-screen if you want local control of your prints.

    Connecting to the phone was the main hurdle that I’ve always seen in developing for cellphone projects, because I have robotics applications in mind. But Octo4a gets around this with low or no effort. Most 3D printers are designed to run on USB anyway, so connecting it to the phone is as simple as buying a USB OTG cable. With the USB port taken over, powering the phone long-run becomes a tiny problem, which can be solved with a Y-cable or a little solder. Keep the OS from going to sleep, somehow, and it’s problem solved!

Barry's Latest Progress With EasyOS Development

  • Balsa email client

    I have chosen an older gtk2 version, 2.4.7, as it has configure choices that suit EasyOS. For example:
    It integrates with Osmo personal information manager. I haven't tested this, so don't know how it works.
    It uses the libgtkhtml v2 library to render HTML emails. This is great, as libgtkhtml v2 is already in EasyOS, used by helpsurfer local document viewer, and Osmo.

  • JWM menu button text is broken

    I want to bring out a new release of EasyOS in a couple of days, so if the problem isn't resolved quickly, I will roll back to 1685. Actually, 1685 works fine, I have had no issues with it, so really why upgrade just because there is a later version?

  • Kernel 5.10.83 compiled

    It was compiled with the 5.10.39 kernel, but was removed afterward.

    OK, it has returned. It must be understood of course, that the wl.ko module conflicts with others, hence has to be a separate PET. It means that every time you upgrade to a later version of EasyOS that has a later kernel, you will have to un-install the PET and install the one that matches the new kernel.

  • Mapping all download folders to one folder

    With the introduction of non-root client applications, there are multiple download folders. For example, firefox runs as user 'firefox', with home folder 'home/firefox', and default download path /home/firefox/Downloads'.

    OK, but if we have more non-root client apps, each with its own Download folder, it is starting to become inconvenient. Perhaps. Forum member hundido was showing a grandma how to use EasyOS, and she liked it, except for all these different download paths...

  1. How to install AnyDesk on Debian 11 Bullseye Linux - Linux Shout

    In this tutorial, we will learn the commands to add a repository of AnyDesk on Debian 11 Bullseye or 10 Buster. Those who don’t know about this app- AnyDesk is a popular and very simple to use remote server or desktop management application. It allows the users to control other computers remotely, or to control your computer remotely. The free remote access software is the alternative to Teamviewer.

    Although Teamviewer is de facto standard when you want to access a third-party computer and control it remotely. But with Anydesk there is a powerful alternative. In terms of functionality, both are very similar; apart from the remote desktop graphical access, both also offer functions such as file transfer and chat. The software is free for private users. For commercial use, companies have to go for a monthly subscription.

    AnyDesk is a cross-platform app, hence apart from Linux also available for Windows, macOS, iOS, and Android. If this app is not the one you like then we also have covered the steps to install TeamViewer on Debian 11, you can go for that.

  2. Install TeamViewer on Ubuntu 22.04 Jammy | 20.04 Focal - Linux Shout

    Well, if you are thinking about how you can easily install the TeamViewer Remote desktop app on either Ubuntu 22.04 Jammy JellyFIsh or Ubuntu 20.04 LTS Focal fossa? Then here is the solution.

    Teamviewer is a popular and cross-platform application to access the remote desktop or server graphical user interface. It is free for personal usage but unfortunately, commercial users have to buy its license.

    Apart from remote access, the user can perform chat, video conferencing, file transfer, remote printing, and more. It offers high security by providing end-to-end 256-bit AES encryption.

    In this guide we are going to set up an sftp server on an Arch Linux system. We will also set up a form of chroot where users can only access sftp with the shared credentials.

    The File Transfer Protocol is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network.

    FTP isn’t popular today because it Lacks Security. When a file is sent using this protocol, the data, username, and password are all shared in plain text, which means a hacker can access this information with little to no effort. For data to be secure, you need to use an upgraded version of FTP like SFTP.

    SFTP Secure File Transfer Protocol is a file transfer protocol that provide secure access to a remote computer to deliver secure communications. It leverages SSH – Secure Socket Shell and is frequently also referred to as ‘Secure Shell File Transfer Protocol’.

  9. K3XEC | Receiving BPSK symbols (Part 3/5)

    This post is part of a series called "PACKRAT". If this is the first post you've found, it'd be worth reading the intro post first and then looking over all posts in the series.
    In the last post, we worked through how to generate a BPSK signal, and hopefully transmit it using one of our SDRs. Let’s take that and move on to Receiving BPSK and turning that back into symbols!

    Demodulating BPSK data is a bit more tricky than transmitting BPSK data, mostly due to tedious facts of life such as space, time, and hardware built with compromises because not doing that makes the problem impossible. Unfortunately, it’s now our job to work within our imperfect world to recover perfect data. We need to handle the addition of noise, differences in frequency, clock synchronization and interference in order to recover our information. This makes life a lot harder than when we transmit information, and as a result, a lot more complex.

I was hoping to wrap up my Pango work after the previous update, but unexpected trouble came in from the side – Benjamin made GtkLabel more serious about height-for-width, and that uncovered some inaccuracies in Pango’s line wrapping implementation. Sometimes, we would make our lines shorter than necessary, and ometimes, we would let a hyphen leak out of the allotted width, creating an overlong line.

Fixing all this up took some serious effort, but I think it was time well spent. One of the outcomes is that Pango now has APIs to serialize PangoLayout objects, and these are used in the testsuite.

Genode OS Framework release 21.11

Filed under
OS

Genode 21.11 puts the spotlight on device drivers. Interactive Genode scenarios come to the Pinephone, hardware-accelerated graphics becomes available on Intel Gen9+ and Vivante GPUs, and Xilnx Zynq receives new love.

The previous release presented our new take on porting drivers from Linux, and the architectural integration of hardware-accelerated graphics in Genode-based systems. The just released version 21.11 is the continuation of both topics. Thanks to our streamlined approach for transplanting Linux drivers to Genode, we were able to reuse the Pinephone's Linux drivers for the display and touchscreen without modification. But, in contrast to running those drivers in the Linux kernel, we are walking on new ground by confining each driver in a separate sandbox.

With our GPU line of work, we followed two major directions during the release cycle. For one, we applied our architectural approach to a second GPU vendor besides Intel, namely the Vivante GPU as used by the i.MX SoC family. Combined with the etnaviv Gallium driver of the Mesa library, Genode thereby becomes able to render graphics with hardware acceleration on the MNT Reform open-hardware laptop. The second branch is the promised extension of our custom Intel GPU multiplexer to GPUs of generation 9 or newer. Thereby, GPU support has now become a regular feature of the Genode-based Sculpt OS that can be taken for a spin on commodity PC hardware.

Another release is available for testing: IPFire 2.27 - Core Update 162. It comes with a brand-new kernel based on Linux 5.15, and it will be the last release supporting the i586 architecture.

Once a few releases after upgrading to Linux 5.10, we have now rebased the IPFire kernel on Linux 5.15. Due to dropping or upstreaming our patchset this was a lot easier than the previous step to 5.10.

The new kernel is long-term supported by the Linux kernel developers and comes with various new drivers and performance improvements. Noteworthy are various performance improvements on "zero copy" for increased throughput and lower latency; Core Scheduling (for safer Hyperthreading), and a new drivers for NTFS.

Despite the growing list of Linux distributions, Linux is now as straightforward and intuitive as other operating systems. Unlike Windows, which only allows you to install apps from .exe files and the Windows Store, Linux has APT (Advanced Package Tool), which handles the installation and removal of packages/apps in the operating system.

If you want to install a program on Linux, you’ll need to use the term apt-get, but what exactly is it, and what does it do? In this article, let’s sudo apt get-started to find out what apt-get is.

Valve says DayZ and five other games are now anti-cheat ready for Linux (and Steam Deck)

Linux
Gaming

Valve’s Steam Deck handheld won’t have any exclusive games, but it is slowly filling in some holes in its Windows game library — Valve says Arma 3, DayZ, Unturned, and Planetside 2 now have functioning BattlEye anti-cheat when you’re using the Proton compatibility layer to play Windows games in Linux. That brings the total to six games, including Ark: Survival Evolved and Mount & Blade II: Bannerlord. (Those two already had support as of November 8th.)

That compatibility is important for Linux in general (and the Steam Deck handheld specifically) because they don’t play Windows games out of the box unless they work with Proton, and third-party anti-cheat software is known to interfere.

But for two of the most popular flavors of anti-cheat, this shouldn’t be a difficult fix! Epic Games has said enabling Easy Anti-Cheat (EAC) in Proton should take “just a few clicks” in the game developer portal. Valve has said enabling BattlEye is as easy as sending an email.

    Between the previous 3.0.7 and this 3.0.16 release I updated some of the vlc packages’ internal libraries too: bluray, dav1d, dvdnav, dvdread, dvdcss, ebml, libva, matroska, opus, pcre2, speexdsp, ssh2 and vpx. I also added patches to the internal ffmpeg that fix crashes in MPEG2 DXVA playback.

  • So it turns out Google would like to pass Knative to the Cloud Native Computing Foundation after all

    What a difference two years makes. Knative has applied to become a Cloud Native Computing Foundation (CNCF) incubating project.

    Google had insisted in 2019 that it would not be donating the framework to any foundation "for the foreseeable future" but a few short years later it has kicked off the process to donate the IP, trademark, and code to CNCF.

    CNCF was obviously cock-a-hoop about the whole thing, and Priyanka Sharma, the foundation's executive director, told The Register: "Knative is a powerful technology that is enmeshed in the cloud native ecosystem making it easy to run serverless containers on Kubernetes. We welcome the decision and look forward to the Knative community contribution as it goes through the CNCF project proposal process.

    In this tutorial, we will show you how to install RPM Fusion on Fedora 35. For those of you who didn’t know, The RPM Fusion software repo is a community-maintained software repo that provides additional packages for Fedora Linux which is not distributed by the official Fedora team. RPM Fusion’s goal is to make the end-user experience as simple as possible by centralizing as much add-on software as feasible. The RPM Fusion repository comes in two variants, Free and Non-Free.

    Give your Roblox games a visual upgrade by building new graphics in Blender 3D.

    Contemporary video games have grown increasingly complex in terms of graphics and mechanical designs, with their realistic textures and immersive environments. Unfortunately, Roblox's default, blocky environments prevent developers from matching those robust worlds. Well, developers can now cast those limitations aside. Roblox now has the ability to import custom mesh objects, so game makers no longer need to endure blocky parts and basic worlds. If you want to try your hand at building beautiful Roblox games, follow these steps to create custom meshes. But first, some background.

  • Security, Privacy Risks of Artificial Intelligence in Healthcare

    “There are multitudes of ways in which AI is particularly useful in the healthcare context. But there are a whole host of concerns in terms of how we regulate AI, particularly because AI is so dependent on gathering large blocks of data in order to learn,” Malek explained. “When you consider that, you see that there are data privacy and cybersecurity issues, ethical issues, and safety issues.” The volume of data that AI models can maintain is staggering. Without the proper safeguards and regulatory assurances, AI could pose risks to patient data security and privacy. When it comes to protected health information (PHI), covered entities have a duty under HIPAA to protect patient data. Engaging with any third-party vendor comes with risks that should be carefully assessed.

Windows Vs Linux: 7 Reasons To Switch To Linux

The view that Linux is a server operating system only is an outdated view. There are hundreds of Linux distributions designed specifically to be beneficial for the average desktop/laptop user, and it is perhaps time you consider switching to Linux from Windows. When we talk about switching to Linux, we talk about using distributions like Ubuntu or Linux Mint instead of your Windows installation. Of course, you don’t have to get rid of Windows at the same day either; you can install Linux side by side with Windows if you wish, until you have finally made your mind about it. Read more
