I've been working a lot with FreeCAD since I got my 3D printer. It's been a mostly excellent experience, but I've run a couple issues. Between the MacOS and Linux version of FreeCAD (both 0.19, maybe different builds?), and transferring files between machines using Nextcloud, a project that I'd been working on for a couple days became broken to the point where I could no longer modify the sketches, rendering it useless.
I've been writing a lot of GraphQL resolvers in ruby at work recently, and frequently run into a situation where I have to align many columns of text by hand. I figured this isn't a very unique problem, and that there was probably already some code within Emacs to handle it. As it turns out I was correct in my assumption. There's an excellent built-in package called align that takes care of just that.
I recently made a post about how I was able to configure the new tab page in my browser to display my org agenda. Since then I've been working on another project similar to that, trying to take the concept even further. A while ago I purchased an Inkplate 6 during its crowd funding stage on Crowd Supply, with the exact intention of creating something like this. At the core of the Inkplate 6 is the ESP32.
I absolutely love org mode. I use it extensively almost every day to keep track of tasks and due dates, both for my personal life and at work. A lot of this workflow centres around the org agenda, which compiles all the current and upcoming tasks and due dates from several files into a single view. The only gripe I had with it was that I had to be within Emacs to use it.
I manage a lot of servers. Some are serving static content like this blog, with others running services like Nextcloud, ZNC, Shadowsocks, or Mumble. I also have one or two game servers to play with my family and friends. These are spread across two providers for cost and geographic reasons. In addition, I have several machines running in my house, one running FreeNAS with some jails, another running Proxmox with several VMs and containers.
Not too long ago I purchased a Samsung Galaxy Tab A. I bought it mostly for browsing the internet and reading PDFs, but I've been using it a lot more for working in Emacs recently. With the help of Termux, I've gotten more or less a fully functional development and writing environment which has both a small physical size, and long battery life. With the use of a bluetooth keyboard, I have everything required to work, and comfortably at that.
I recently purchased some products from Hak5, some of which integrate with their self-hosted service for monitoring your equipment called the Cloud C2. I decided to run it on one of my servers which runs one of my favourite Linux distributions, Alpine Linux. You have the option to purchase the community edition for free from their shop, after which you'll receive a product registration code via email. This email will also contain a link to download the Cloud C2 software, which are distributed as (mostly) statically linked go binaries for several platforms all bundled together in a zip folder.
The Problem Say you have an account with a VPN provider. Maybe there are a limit to how many connections you can have with one account. Maybe you want to put more machines than you have connections on the account. Or maybe you want to put a large number of machines of the connection, maybe some FreeBSD Jails, LXC containers, or VMs, and you don't want to download the VPN profiles, sign in and configure them all individually.
I recently gave a talk at work to help introduce OpenBSD to my colleagues. It's a broad introduction to the fundamentals of security in OpenBSD, as well as some basic system administration tips and suggestions anyone coming from a Linux background might find useful. It's roughly split up into four sections; the history of OpenBSD, what sets it apart from other operating systems, a guided installation, and the system administration introduction.
