Single-player tile-matching game, commonly known as Mahjong solitaire.
 Tiles are stacked on the board at the start of the game. The goal is to
 remove all the tiles in as little time as possible.
 Select two matching tiles and they will disappear from the board, but
 you can only select a tile if there is an empty space to its left or
 right at the same level. Be careful: tiles that look alike may actually
 be slightly different.
 
 
 You can choose from a variety of starting layouts, some easy and some
 difficult. If you get stuck, you can ask for a hint, but this adds a
 large time penalty.

Obsidian is a powerful knowledge base that works on top of a local folder of plain text Markdown files. In Obsidian, making and following connections is frictionless, and with the connections in place, you can explore all of your knowledge in the interactive graph view. Obsidian supports CommonMark and GitHub Flavored Markdown (GFM), along with other useful notetaking features such as tags, LaTeX mathematical expressions, mermaid diagrams, footnotes, internal links and embedding Obsidian notes or external files. Obsidian also has a plugin system with 20+ supported plugins to expand its capabilities.
      The documentation can be accessed by opening the demo vault that is shipped in Obsidian.
      Obsidian will always remain free for personal use, no account or license is required for qualifying use cases described in the End User License Agreement. However, commercial users should purchase a license on Obsidian's website. Users also have the option to purchase a Catalyst license to get early access to insider builds and support the development. Additionally, Obsidian offers an optional paid hosting service for your notes. Details about this optional hosting service can be found on the Obsidian website.
      This distribution is verified by the Obsidian team but isn't supported
      Wayland support can enabled with --socket=wayland in Flatseal which can enable features like pinch zoom
      GPU acceleration can be disabled if necessary by setting OBSIDIAN_DISABLE_GPU=1 in Flatseal
      Pdflatex support in pandoc currently requires installing the org.freedesktop.Sdk.Extension.texlive SDK
      Note: Regular users should disable "Automatic Updates" within Obsidian as public release updates are handled by Flatpak itself. Insiders should keep this enabled to receive insider builds, as those will not be made available on Flathub.
      This flatpak goes into great lengths to provide a nice experience for end users. In order for the Git plugin to work it requires permission to the ssh-auth socket (--socket=ssh-auth). It also exposes the home directory in the sandbox (required for Drag and Drop operations). If you don't use the Git plugin you can disable the ssh-auth socket permission, e.g. using Flatseal. You can also remove access to the home directory if you want and the flatpak will continue to work, albeit with reduced functionality. In case you do remove access to the homedir, note that in order for things to not break for the Git plugin, --persist=.ssh flag has been passed and a bind mount to ~/.var/app/md.obsidian.Obsidian/ is created by flatpak, allowing that location to be used for persistent data (but your home directory's .ssh remains unaccessible)

Block editing: SiYuan, the only important core concept is Content block. The content block
      can be formed through the formatting format, so that we can organize our thoughts and
      knowledge at the block-level granularity, and it is also convenient for reading and outputting
      long content.
      Privacy security Encrypted cloud, worry-free privacy: Data is stored entirely on the device
      under the control of the user. Even if there is no network, even if the cloud service is down,
      it can still be used locally without restrictions. No offline, no notes.
      Bidirectional link: Documentation page are also blocks, reducing mental load. All content
      exists on a block basis, and documentation pages are no exception. Blocks can be converted to
      each other, splitting, reorganizing and moving do not affect existing links.
      List outline: Sort out the main points, logically layered
      Multi-device data sync: Keep data complete and consistent

            This is a screen recorder that has minimal impact on system performance by recording a monitor using the GPU only, similar to shadowplay on windows. This is the fastest screen recording tool for Linux. This screen recorder works on X11 and Wayland on AMD, Intel and NVIDIA.
        
      
            This screen recorder can be used for recording your desktop offline, for live streaming and for nvidia-like instant replay, where only the last few minutes are saved.
        
      Supported video codecs:
      
        H264 (default)
        HEVC (Optionally with HDR)
        AV1 (Optionally with HDR. Not currently supported on NVIDIA if you use GPU Screen Recorder flatpak)
        VP8
        VP9
      
      Supported audio codecs:
      
        Opus (default)
        AAC
      
      
            Recording a monitor requires (restricted) root access which means that you have to install GPU Screen Recorder system-wide: "flatpak install flathub --system com.dec05eba.gpu_screen_recorder"
            and pkexec needs to be installed on the system and a polkit agent needs to be running.
            Note that this only applies to when recording a monitor on AMD/Intel or when recording on Wayland without using the desktop portal option.
        
      AV1 is currently not supported in the flatpak for Nvidia since GPU Screen Recorder uses an older ffmpeg version to support older Nvidia cards. Install GPU Screen Recorder from source or from AUR if you want to use AV1 on Nvidia.
      
            Videos are in variable framerate format. Very out of date video players might have an issue playing such videos. It's recommend to use MPV to play such videos, otherwise you might experience stuttering in the video.
            You can select constant frame rate mode in advanced view if you need it.
        
      
            If the video doesn't play or you get green/yellow overlay then your video player is missing H264/HEVC video codec. Either install the video codecs or use mpv.
        
      AMD has a driver/hardware fault that causes black bars/distorted colors on the sides of the video for certain video resolutions. This happens for both av1 and hevc, so if you have this issue then switch to h264 video codec option in advanced settings.
        
      
            If H264/HEVC video encoding option is not available on your AMD/Intel system but you know that your GPU supports those codecs for encoding then you may need to install mesa-extra freedesktop runtime by running this command: "flatpak install --system org.freedesktop.Platform.GL.default//23.08-extra".
        
      
            On NVIDIA systems the flatpak NVIDIA driver needs to match the systems NVIDIA driver version or the NVIDIA driver will fail to properly load in flatpaks.
            Make sure you update flatpak on your system with: "flatpak update", or if that doesn't fix it you can try to install the specific flatpak NVIDIA driver version version that matches your systems NVIDIA driver version by running:
            "flatpak install org.freedesktop.Platform.GL.nvidia-version", for example "flatpak install org.freedesktop.Platform.GL.nvidia-550-54-14".
            You can find which NVIDIA driver version is running on your system by running "cat /proc/driver/nvidia/version".
        
      GPU Screen Recorder flatpak can install files in $HOME/.local/share/gpu-screen-recorder. If you want to uninstall GPU Screen Recorder then you will have to remove this directory manually.

      Bitwarden is the easiest and safest way to store all of your logins and
      passwords while conveniently keeping them synced between all of your
      devices.
    
      
      Password theft is a serious problem. The websites and apps that you use
      are under attack every day. Security breaches occur and your passwords
      are stolen. When you reuse the same passwords across apps and websites
      hackers can easily access your email, bank, and other important
      accounts.
    
      
      Security experts recommend that you use a different, randomly generated
      password for every account that you create. But how do you manage all
      those passwords? Bitwarden makes it easy for you to create, store, and
      access your passwords.
    
      
      Bitwarden stores all of your logins in an encrypted vault that syncs
      across all of your devices. Since it's fully encrypted before it ever
      leaves your device, only you have access to your data. Not even the
      team at Bitwarden can read your data, even if we wanted to. Your data
      is sealed with AES-256 bit encryption, salted hashing, and PBKDF2
      SHA-256.
    
      
      Bitwarden is 100% open source software. The source code for Bitwarden
      is hosted on GitHub and everyone is free to review, audit, and
      contribute to the Bitwarden codebase.
