Over the course of many complex projects, I have gained proficiency in designing, implementing, and maintaining robust and scalable infrastructures. My experience covers optimizing performance, ensuring high availability, and enhancing system security while working with web servers, load balancers, databases, CI/CD pipelines, containers, and serverless technologies.

I’ve recently read Using Plaintext Email by Kev and completely agreed with his reasoning on why reasons noted on the website are a bit silly, but that also got me thinking, why is Plain-text really better? Why do I personally prefer it? Although I am one of those nerds preferring to use command line email client...
As noted in the previous article on this blog, in the next episode of the “Self-Hosted Kubernetes Adventures” sitcom, I’ll explain how I configured HAProxy as an Ingress Controller, and how I issue TLS certificates within the cluster using cert-manager. I’ll also mention some plans for the future, because future is...
Over the years I have dabbled with Kubernetes on-and-off a bit, and mostly learned theoretical stuff surrounding it. I also managed and deployed few of the EKS based clusters on AWS at work, so I know certain operational things as well. To be honest, I haven’t really done any “cool and amazing” things with it. Those...
As you probably know, this website is based on an amazing static website generator Hugo. I’ve been more than happy ever since I switched to it more than two years ago . In the beginning, I deployed website directly from my local machine to the S3 and then invalidated Cloudfront cache as described in the article....
Miniflux With setting up nextcloud I have prepared most of the building blocks and am ready to start migrating simpler services back to my local network. First thing I migrated was Miniflux. I have chosen this one since it is in essence very simple service. What I needed was: PostgreSQL database Miniflux And...
Ever since I started this website I’ve some kind of way to leave a comment on the article, with a brief exception when I turned off the comments and then shortly turned them on again . In the beginning I used built-in system in Wordpress, then switched to Disqus, and at last decided to switch to Commento self-hosted...
In a sea of information, staying up-to-date with the latest news, blogs and updates can be an endless task. After some time of surfing the web you gather a list of your preferred sources and you want to know when they publish something new. I don’t really stay up-to-date much with generic news. From time to time, I...
After setting up Intel NUC with Debian 12 on top of it, I have decided to configure Nextcloud as my first application on this new setup. In order to have a successful setup for my needs, I have decided on the following: DNS name for accessing the installation (static DNS entry on the network + valid TLS certificate)...
For the past few weeks, and over the next few weeks, I have been playing with my local network setup and am hoping to migrate most of the self-hosted services I use and have scattered throughout the various server providers to my local network. Except of those that should be on the web obviously (Mastodon instance,...
These days there are plenty of password managers out there, all providing the same base promise; making you more secure by using random password for each of the accounts you have. Obviously this has one caveat, where you have “all eggs in one basket”. If this account gets compromised, attacker would have access to...
Since I’m using MacOS again for the work, and obviously, I still use Emacs, I wanted to have a functionality which would detect which system theme is being used and load the correct one during Emacs startup. Previously, I have hacked together just a simple script which depended on GTK theme. Basically, If command...
My GPG setup consists of two Yubikey keys, each holding same set of keys in its internal storage. Reason behind this is that keys can’t be exported from the Yubikey (at least you shouldn’t be able to do that). There’s also the PIN protecting the usage of those keys. There are also additional security mechanisms...
