Getting Fractal up to speed

Fractal is a popular Matrix chat client for the GNOME desktop which has been in development since 2017. Fractal was designed to work well for collaboration in large groups, such as free software projects. However, there are still two main areas where it would benefit from improvements: its performance and maintainability are limited, and it lacks some important features such as end-to-end encryption (E2EE). Adding E2EE will increase the confidence that users have in the privacy of their conversations, making it nearly impossible for their conversations to be accessed by others. Because E2EE aims to prevent the service provider from being able to decrypt the messages, because the encryption keys are stored only on the end-user’s device. The direct consequence of this is that some work is delegated to the client. Some of this functionality is the same for each and every Matrix client, and includes technical components that could easily be implemented in the wrong way (especially the various encryption and security features). Most security researchers agree that redoing this work is a bad idea as it can lead to vulnerabilities. More generally, reimplementing the same functionality for each client doesn’t make much sense. On the other hand, sharing it with others allows projects that use it to contribute their expertise and polish it together instead of competing on a multitude of implementations. That shared work is called an SDK and could be considered the future “engine” of Fractal. When Fractal was created, there was no existing code that we could rely on. We had to implement ourselves bits of the Matrix protocol in Fractal, at a low level. In the meantime, the Matrix Foundation has kickstarted matrix-rust-sdk, a library to channel the Matrix community efforts into a common, efficient library. This library, still in development for now, will allow us to drop a lot of our own code.

• How to add PHP support for jailed SSH users in ISPConfig 3

  Jailkit is an easy-to-use tool to create and maintain jail environments for shell users on Linux. In this guide, I will show you how to move PHP and its dependencies into the jail so that the jailed user can execute PHP scripts inside the jail on an ISPConfig server.

• Installing other DEs in Nitrux

  During last month’s release of Nitrux, we made available a minimal ISO to let users install Nitrux and also install a different desktop environment and a selection of applications than the ones we include by default. We figured it’d be simpler to do this since we don’t have any plans to release different ISO images with different desktop environments.

• How to clear Bash history on Linux

  The bash history is a log file that contains all commands that the user executed on the Linux shell. When you use the "arrow up" key on our keyboard, then Bash will look up the previous command from that file and display it on the screen, ready to be executed again.

• How to set a VNC password

  The Linux TigerVNC Server provides a command to set a new password.

• How to kill an OpenVZ Container

  This guide shows you how to kill an unresponsive OpenVZ container in case the normal stop procedure fails. Killing the container will not delete any files or remove the container, it just kills all processes so that you can start or restart the container again when it gets stuck. I will use container ID 101 in all commands, please replace that ID with the ID of the container that you like to kill.

• How to install TagScanner on Ubuntu 20.04 LTS Linux - Linux Shout

  TagScanner, a freeware program, is only available for Windows 10/8/7/ to easily edit metadata information of audio or music files. However, that doesn’t mean we cannot install and use Tagscanner on Linux systems such as Ubuntu, Linux Mint, and others, yes we can using Wine. You can get TagScanner for both 32-bit and 64-bit systems. It is one of the popular tools to edit audio file metadata and available to download free of cost from official or third-party websites. Let’s see the steps involve to run Tagscanner on Linux systems.
