SimpleX Is a Chat Network That Preserves Metadata Privacy

SimpleX is an open-source decentralized client-server network that uses disposable nodes to asynchronously pass the messages, providing receiver and sender anonymity. Messaging apps make it easy to communicate and connect with people around the world.

Windows box won't boot? SystemRescue 9 may help

The latest version of an old friend of the jobbing support bod has delivered a new kernel to help with fixing Microsoft's finest. It used to be called the System Rescue CD, but who uses CDs any more? Enter SystemRescue, an ISO image that you can burn, or just drop onto your Ventoy USB key, and which may help you to fix a borked Windows box. Or a borked Linux box, come to that. SystemRescue 9 includes Linux kernel 5.15 and a minimal Xfce 4.16 desktop (which isn't loaded by default). There is a modest selection of GUI tools: Firefox, VNC and RDP clients and servers, and various connectivity tools – SSH, FTP, IRC. There's also some security-related stuff such as Yubikey setup, KeePass, token management, and so on. The main course is a bunch of the usual Linux tools for partitioning, formatting, copying, and imaging disks. You can check SMART status, mount LVM volumes, rsync files, and other handy stuff. Usefully, there's also a full local copy of the website and all documentation, including a console-mode web browser to read it with. Read more

  • Hosting my static sites with nginx

    Originally I thought that running my own servers would require a lot of maintenance and be a huge pain, but I was chatting with Wesley about what kind of maintainance their servers require, and they convinced me that it might not be that bad. So I decided to try out moving all my static sites to a $5/month server to see what it was like. Everything in here is pretty standard but I wanted to write down what I did anyway because there are a surprising number of decisions and I like to see what choices other people make.

  • How to convert Centos 8 Linux to Alma Linux 8

    CentOS Linux 8 was discontinued at the end of 2021. Check out more information about that in this in this article CentOS Linux 8 will end in 2021 and shifts focus to CentOS Stream. The team at CentOS decided to shift focus to CentOS stream, an upstream version of RHEL. CentOS stream places itself between Fedora Linux and RHEL. It is not 100% RHEL clone but ahead of RHEL development. Other distros that are 100% compatible with RHEL 8 have come up including Rocky Linux and Alma Linux. In this guide, we will learn how to convert an existing CentOS 8 distribution into Alma Linux without reinstalling a new operating system.
