My main PC workstation (as opposed to my Mac Pro) is a dual-boot Windows and Linux machine. While backing up the Windows portion is relatively easy via some cheap-ish commercial backup software, I ended up backing up my Linux home directories only very occasionally. Clearly, Something Had To Be Done ™. I had a look […]

Why do we need another post cluttering up the Interpipes on how to find a set of documents in a MongoDB collection that contain a non-empty array field? It’s not like we suddenly have a shortage of posts and articles on this topic after all. Well, it maybe a shocking revelation but not all of […]

In part 2, I reconfigured my WireGuard VPN to use an Unbound DNS server on the VPN server rather than rely on a third party server I had used for the original quick and dirty configuration. It was important for me to set up a validating DNS server, which I did in that part. In […]

In the first part, I described how I set up the basic OpenBSD WireGuard VPN server. I also hinted that I wanted to set up my own validating, filtering DNS server. With a little bit of spare time during the holidays I decided now was a good time as any. Making sure the VPN server […]

In my previous post, I mentioned that I somehow ended up with a corrupted filesystem on the WireGuard server I had set up earlier this year. That iteration of my VPN server was built on Linux as I expected I would get better performance using the kernel-based WireGuard implementation. It had taken me a while […]

I’ve blogged about setting up a WireGuard VPN server earlier this year. It’s been running well since, but I needed to take care of some overdue maintenance tasks. Trying to log into the server this morning and I am greeted with “no route to host”. Eh? A quick check on my Vultr UI showed that […]

MongoDB has a handy command to rename a collection, db.collectionName.renameCollection(). There is currently no equivalent to rename a database. Now if we accept that from time to time, one positively, absolutely just has to rename a database in MongoDB, well, there are a couple of options. Unfortunately they aren’t quite as straight forward as single […]

My previous instructions for installing a newer Emacs version on Ubuntu still work. Ubuntu (and in my case, XUbuntu) 19.04 ships with Emacs 26.1 out of the box. As usual I want to run the latest version – Emacs 26.3 – as I run that on my other Linux, FreeBSD and macOS machines. I only […]

I like Lispy languages. One I’ve been playing with – and occasionally been using for smaller projects – is Clojure. Clojure projects usually use Leiningen for their build system. There are generally two ways to install leiningen – just download the script as per the Leiningen web site, or use the OS package manager. I […]
