Using Restic with systemd on Linux

You can read the Russian version of this post here.

Restic, the simple backup program, is a fairly well-known piece of software. Designed to be simple to both use and script on any system, it doesn’t include any OS-specific setup examples, which is precisely what this post describes.

So what we’re trying to achieve here:

  1. Automated backup runs daily at 12:00 AM (or any configurable time).
  2. The backup includes only important configuration files and data stores.
  3. The backup also includes all PostgreSQL databases, restorable with psql -f.
  4. The backup expands to an unlimited number of repos on need.

Running a Gemini site with gmnhg and Hugo

This site has recently got its Gemini version thanks to the tool I wrote, gmnhg, available at gemini://tdem.in. The tool has already met its first milestone, v0.1.0, so this is likely a good moment to recap on the whole idea of working in a Hugo site into the Geminispace.

Remote debugging with VSCode without Remote Development

This post is available in Russian here.

There’s a certain point in life in which you realize you need to debug a program that simply cannot be run on your working machine due to reasons. In my case I have to debug a program that communicates with iwd, the Intel wireless daemon for Linux. My workstation doesn’t have a Wi-Fi adapter, so I needed some sort of a remote debugging hack.

Toggling dunst notifications in i3

In case you always wanted to write a script that temporarily turns off dunst notifications in i3wm but have never taken the time to write one yourself, here, have a working implementation in bash.

Making dnscrypt-proxy and Docker play well together

This post is available in Russian here.

DNSCrypt is a fairly popular way of protecting DNS traffic that is usually left unencrypted from other people. dnscrypt-proxy, a client program that implements DNSCrypt, also supports the DNS-over-HTTPS protocol, allowing name resolution over DoH.

Unfortunately, leaving dnscrypt-proxy with its default settings while setting it as the default resolver breaks name resolution in Docker containers. Fixing this while not exposing a DNS resolver on the LAN is what’s described below.
