      • How to use Syncplay for videos on Linux | FOSS Linux

        Syncplay is a free, open-source application that allows users to synchronize their media players with remote peers to view videos together. It is available for Linux, Microsoft Windows, macOS, and *BSD. It supports the following media players: MPV, MPC-HC, VLC, and MPC-BE, with each user having the option of using any of them.

        Thus, it doesn’t make a difference whether or not you use Linux and your buddies use Windows or macOS. On the internet, you may still participate in a shared video experience.

        Syncplay’s objective is to synchronize the position and play state of a video across several users. This implies that whenever one user searches or pauses the video, the effects are shared with all other connected users. You may either use one of the publicly available free Syncplay servers or run your public or private Syncplay server on Linux, Windows, or macOS.

        We’ll discuss every aspect you need to know about Syncplay in this tutorial, including its features, how it works, and, most significantly, how to use it. Thus, without further ado, let us begin!

      • DedoimedoHow to install and use Kerkythea in Linux - Tutorial

        Welcome. This article is part of my ongoing series on moving away from Windows as my primary operating system. Several months ago, I've come to the conclusion that the days of the sane, classic desktop computing in Windows are numbered, and I must migrate away ere it's too late. Now, there's no panic. The real problems will most likely start around the EOL of Windows 10, which means 2025 at the earliest. Till then, I promised to do a long series of Windows-to-Linux migration guides around this topic, and create a functional, productive alternative setup for myself, with Linux and the Plasma desktop as my choice.

        So far, I've told you about my generic plan for this adventure. There are some good news already. A fair deal of my favorite software is already cross-platform and/or native to Linux. Other stuff works through WINE. The whole thing will, predictably, boil down to office and games. Now, I want to show you how you can use Kerkythea, a photorealistic, 3D rendering program, in Linux. Follow me.

          Be sure to replace "VMDISK" with the path to the virtual machine image.
        • OpenSSHOpenSSH 9.0
          OpenSSH 9.0 was released on 2022-04-08. It is available from the
          mirrors listed at https://www.openssh.com/.
          OpenSSH is a 100% complete SSH protocol 2.0 implementation and
          includes sftp client and server support.
          
          

          Once again, we would like to thank the OpenSSH community for their continued support of the project, especially those who contributed code or patches, reported bugs, tested snapshots or donated to the project. More information on donations may be found at: https://www.openssh.com/donations.html

          Changes since OpenSSH 8.9 =========================

          This release is focused on bug fixing.

          Potentially-incompatible changes --------------------------------

          This release switches scp(1) from using the legacy scp/rcp protocol to using the SFTP protocol by default.

          Legacy scp/rcp performs wildcard expansion of remote filenames (e.g. "scp host:* .") through the remote shell. This has the side effect of requiring double quoting of shell meta-characters in file names included on scp(1) command-lines, otherwise they could be interpreted as shell commands on the remote side.

          This creates one area of potential incompatibility: scp(1) when using the SFTP protocol no longer requires this finicky and brittle quoting, and attempts to use it may cause transfers to fail. We consider the removal of the need for double-quoting shell characters in file names to be a benefit and do not intend to introduce bug-compatibility for legacy scp/rcp in scp(1) when using the SFTP protocol.

          Another area of potential incompatibility relates to the use of remote paths relative to other user's home directories, for example - "scp host:~user/file /tmp". The SFTP protocol has no native way to expand a ~user path. However, sftp-server(8) in OpenSSH 8.7 and later support a protocol extension "expand-path@openssh.com" to support this.

          In case of incompatibility, the scp(1) client may be instructed to use the legacy scp/rcp using the -O flag.
        • LWNOpenSSH 9.0 released

          OpenSSH 9.0 has been released. It is claimed to be primarily a bug-fix release, but it also switches to a new, quantum-computer-proof key-exchange protocol by default and includes a number of sftp changes, some of which may create some compatibility issues (described in the announcement) with scp.

          A new default GNU Compiler Collection for openSUSE Tumbleweed arrived this week in one of the snapshots that has rolled out in the month of April.

          Snapshot 20220405 made the default compiler switch to GCC 12.

          The most recent snapshot that came out after the switch was 20220406. This snapshot updated five packages. One of those updated packages was autoconf 2.71. Configuration scripts from the latest autoconf improved compatibility with C-variant front end compiler clang and compatibility was restored with automake’s rules for regenerating a configuration. The Linux SCSI target framework tgt package updated to version 1.0.82 and added support for listening on a random port. Other packages to update in the snapshot were xf86-video-dummy 0.4.0 and yast2-slp-server 4.5.0.

        • GamingOnLinuxSorry Arch, it's not working out any more and hello Fedora | GamingOnLinux

          There comes a time when everyone has to sit and think about what they use on their PC, especially if you're on Linux. For me, Arch Linux just wasn't work out any more and so I've moved to Fedora.

          While I was reasonably happy with Arch Linux, it's just not stable enough for me personally. It's a very subjective thing of course, and highly dependent on what hardware you use — along with how often you update. For me, it just messed things up a bit too often, and last night was the final straw.

          Most know that using Git's push --force command is strongly discouraged and is considered destructive.

          However, to me, it seemed very strange to put all my trust in Git with my projects and at the same time completely avoid using one of its popular commands.

          This led me to research why folks consider this command so harmful.

          As an IT leader, you are tasked with delivering solutions that reduce costs, transform the business, and drive revenue. Chances are, one of the biggest hindrances your organization faces is technical debt.

          Technical debt causes friction and can significantly slow the delivery of IT solutions. The result? Your IT team can’t deliver at the scale the business requires. IT leaders must address technical debt in order to meet the needs of the business.

        • GamingOnLinuxRaspberry Pi OS gets some big updates, possible to run experimental Wayland | GamingOnLinux

          Raspberry Pi OS has been through a big update recently, which fans of the little devices need to be aware of for future setups and upgrades.

          First, in the name of security, the default "pi" user is no more. Why? Well, attacks are on the rise, and since the RPi is incredibly popular, it is obviously a target. Removing the default name is just another small barrier that anyone doing something naughty has to overcome, as they might now need your username directly too. That, and new legislation from some countries that forbid having default login info. Seems like a sane change regardless, so their install wizard (that's now required to use) was upgraded to create a proper user account.

          Linux Mint, the distribution that tries to set itself apart for beginners (but not only) along with their own Cinnamon desktop environment, have some plans to help users upgrade.

          Jumping between small releases is currently fine, since Linux Mint sticks to the same Ubuntu package base. However, upgrading to a new major version can be a hassle. Thankfully, they're working on solving this issue with a brand new upgrade tool in the works.

          When you want to install a new program on your computer, the very first thing you ask is the amount of memory this program needs to work perfectly. The reason for this is that before the actual installation, you need to make sure whether your computer system is capable of running the program or not. Also, you need to know how much memory is installed in your system. In this article, we will explain how you can check how much memory is installed on your Ubuntu server or desktop. The commands have been run on an Ubuntu 20.04 system, but they will work in the same way on Ubuntu 22.04.

        • Short history of the "What is Free Software (Open Source)?" video

          In February 2020, I was giving a talk titled "The core values of software freedom" at FOSDEM's largest auditorium (video recording). It was great to talk to such a large audience and have all those great discussions afterwards. Briefly afterwards, in March 2020, I gave the same talk at FOSS Backstage (video recording), especially enjoying the Q&A afterwards. Unfortunately, then the pandemic hit Europe, and it was my last conference in person for that year. So the next months I heavily missed having in person discussions with people I know and with new people I could have met at conferences.

          Nevertheless, I had great online discussions about the topic of the talk, which encouraged me to think about how we can condense the message of the talk further to reach more people with it -- maybe with a short video similar to our "Public Money? Public Code!" video. When one person, who already before sent me kudos for my FOSDEM talk, heard about it, he offered to make a larger donation to cover the costs for such a video.

        • TIC-80 Dino Run

          I was feeling the urge to tinker on a fun project for a change so I started looking more closely into the TIC-80 fantasy console after hearing it mentioned on a podcast.

          It's a lot of fun to develop for. You have certain technical limitations you have to work under, such as a 240x136 display, 16 color palette, and more. Those limitations are oddly freeing in a way. There's not a lot of pressure to create something groundbreaking or innovative, and I found that being restricted only encouraged me to have fun with it.

          [...]

          The editing tools are well made and even pretty fun to use. You can create everything you need for a game -- code, sprites, audio -- while staying inside the TIC-80 environment.

    • I Answer Questions, Part IV



      These social protections have been slowly eroding over decades. Much of our tax money now goes into paying consultants and private schools that feed segregation and inequality. These are not my opinions: these are well documented facts that even the conservatives acknowledge. The problem is that nobody wants to decommission the private schools or private clinics because it would cause short term discord.

      The railroads used to be publicly owned. Railroads were sufficiently serviced. The railway industry now complains about the deteriorating state of railways, but they don't want to pay for repairs and service. That money will end up coming from taxes; public money directly funnelled to the benefit of private companies. I believe the same situation applies to electricity infrastructure.

      Private schools siphon well-off and low maintenance pupils from the public education system and are able to spend less per pupil on average than the public schools who are left with a higher percentage of kids in need of extra support, further straining the budgets, planning, and resource problems that the schools already have.

        We have been pursuing information relating to the scope and scale of e-surveillance conducted by the Ministry of Home Affairs (‘MHA’) since December 2018. The information was, at first, denied on the grounds of national security. Thereafter, on appeal, the information was denied on a new ground that minimal data was maintained and records pertaining to the information sought were destroyed from time to time. When we, further, appealed against this order before the Chief Information Commissioner (‘CIC’), the CIC accepted another new ground - that the information on e-surveillance orders was not maintained at all by the public information officer at the MHA! We have challenged this order of the CIC before the Delhi High Court, which was heard on 05.04.2022. The Court directed the counsel for the public information officers and the MHA to seek instructions on maintenance of records.

This amounts to a choice limit my computing activity to writing, email, and Gemini/Gopher over the weekend.
