Over far too many years I had amassed a collection of mail archives with much overlap (but also enough unique emails to keep the different archives) in different formats. This article is about the effort to unify them (merge), and eliminate (most) duplication, delete emails older than my new ‘personal data retention policy’ (purge), and organize what was left into yearly archives so that it is easy to annually remove no longer relevant emails.

Lightweight Public Git Self Hosting
Public git self hosting can be desirable for a number of reasons, but you may not want the expense and maintenance burden of a GitLab or other ‘full-service’ git hosting options, so this article discusses a lightweight option for a browsing or cloning your git repositories via HTTP/HTTPS (web), as well as pushing, pulling, cloning, etc using SSH.
At the very least it gives you a way to keep a backup you control of your valuable source code and documents that are also on a large central service.
Backing Up is Hard to Do
I went all in with Windows/MS365 and discovered why I love Linux. Take, for example, the ‘backup story’ in Windows versus Linux, a well as the dissonance called InTune.
Windows in a Libvirt KVM VM
These are some updated personal notes about setting up the Windows side of a nice combined Windows and Linux productivity and development environment in Virtual Machine running under Libvirt Qemu/KVM (that is with Linux as the host OS). It uses open source software combined with some key proprietary pieces on a single machine. It is important to note this environment is geared to those who are used to the Linux ecosystem and also want to use or try the new hybrid model.
Intro to Raspberry Pi OS
Raspberry Pi OS is the official operating system for the Raspberry Pi family of educational single board computers. This article discusses some useful information on using Pi OS (including remotely) and provides links to more information.
Raspberry Pi OS for a Server
For small deployments (or home or small office use) you may find yourself in need of a ‘bare metal’ server, but not want or need the expense of an x64 machine. If the workload is not too demanding, a Raspberry Pi can be a good choice. The Pi has the benefit of being inexpensive, using little electricity, and taking little space. This article has been modified to use Raspberry Pi OS as the base instead of a customised Raspbian image.
Windows and Linux in One
These are some personal notes about setting up a very nice combined Windows and Linux productivity and development environment. It uses
open source software combined with some key proprietary pieces on a single machine and avoids the hassles of a full blown virtual machine. It is important to note this environment is geared to those who are used to the Linux ecosystem and are migrating to the new hybrid model.
Raspberry Pi as an Ansible Server
As a base service for bare metal infrastructure I prefer my provisioning and configuration management servers to be bare metal which can be accessed without requiring other hosts or infrastructure. For small deployments the Raspberry Pi makes a great choice because it is inexpensive, uses little electricity, takes little space, and yet has enough power for the relatively low demands placed on the server (which also makes a full x64 server overkill).

Relay Mail From Localhost Using Postfix
Due to SELinux and AppArmor, as well as other permissions issues, simple mail relays like msmtp and ssmtp are no longer viable. Therefore document how to do simple mail relaying with postfix.

Package Installation and Updates on an Isolated Network
For your self-hosted systems there are likely hosts you don’t want exposed to the wilds of ‘The Internet’, even for outgoing traffic, but you still want to be able to do package updates. Here is how you do that using NGINX as a proxy on a host on an isolated network and is also on an internet connected network.
CentOS 7 Partial Mirrors and Custom Repositories
Often you don’t need a full mirror of CentOS and/or only want a small set of packages from other repositories such as EPEL, so to save bandwidth, space, and time we give a working example of a partial mirror and custom repository setup.
Debian Custom CD
Check the Debian Wiki first! Before reading this page you should try looking at the DebianCustomCD Page on the Debian Wiki because it is updated more frequently, and by more contributors. Possibly Simpler Alternatives One possible “alternative” to this procedure is to use the package simple-cdd. It is basically a wrapper around debian-cd and debpartial-mirror… Continue reading Debian Custom CD
