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.

Background I use GPG for encrypting various things locally on my machines. Things like .authinfo.gpg which gets sourced by Emacs and things like that. In past I’ve used it even more when I was actively using Password Store as my password manager. But not to go too much into off-topic, let’s talk about the issue...
Few months back, I’ve had around 30 thousand email messages in my mailbox. Things were hectic to say at least… Every time I’ve opened up my email client, I wasn’t sure about importance of each particular item. There was also the fact that when setting up a new email client and letting it fetch all the headers (IMAP)...
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 “keys to the kingdom” scenario where you only have to watch that one account, and if it...
So today I’ve been looking at the disk space usage and observed rather peculiar thing; my ~/.var/app/ folder was around 30GB in size. Upon further examination I’ve observed that the disk space usage is generated by the Lbry flatpak application which stored its cache of downloaded videos there. What’s rather weird is...
Background Few months ago (less than 3), I’ve switched my website from Wordpress to Hugo . There I described the process of setting up Cloudfront distribution to serve as a CDN and a simple web-server for the content backed by S3 bucket. One of the challenges was how to serve nested paths (eg. /about-me/) as...
You’ll be amazed how much things you can learn about the process on the Linux system by exploring and poking around /proc/. ProcFS in Linux is a special filesystem that contains various information about the system, processes running on the system and allows you to adjust some of the things by writing directly to...
BTRFS - the filesystem that was first introduced in 2009, back in the days of Linux 2.6.x kernel. It came with a promise of being this modern filesystem, for the modern age. Packed with all sorts of features that were traditionally being considered as part of the “Software RAID” or “Volume manager”. To this day, it...
On the old Wordpress-powered site I have used “Koko Analytics” software for tracking some basic data about visitors of this blog. Nothing fancy to be honest, I was only getting information from where did visitors come from, what were their referrals and which articles were most popular. I could’ve easily done it by...
You may have noticed that this site is a bit different in the past few days. It is simpler, faster, and overall nicer! As I’ve published few days ago, I have decided to make some changes to my existing website and have decided to set it up as a statically generated website powered by Hugo , using amazing PaperMod...
Hi there! If you’re reading this it means that you have reached my new Hugo based website! I will write more detailed post about the whole new setup in a few days, in the meantime, if you notice that anything is broken, please feel free to reach out to me via the email noted on the homepage :-)
Last month/year I decided to challenge myself and embark on the journey of using OpenSUSE to give it a fair chance to become my daily driver. It is really hard to say if I’ve given it a fair chance, but during the journey I’ve learned OpenSUSE is not the right distribution for me. I have tried both Leap and...
Yesterday I decided to give Cinnamon a try on my main desktop. My main desktop runs Fedora 33 Workstation edition and I have been fully enjoying GNOME on it. It is modern, simple, and yet, quite fast on my machine. So, why the change? Things got boring. This is great on machine that has to be rock-solid, and Fedora...
