Years ago, when my old company was decommissioning hardware, I bought the 2017 MacBook Pro from them, the 13" A1708 with function keys instead of the Touch Bar.

Every homelab reaches the point where you deploy a new service, it gets an IP, and then you trot off to the router UI to add yet another DNS record by hand.

Sooner or later every one of us meets it: some service that has been running fine for months suddenly starts logging Too many open files, and most of the internet’s advice is to raise some limit to a million and move on.

We all know the drill by now.

We all know the drill.

Almost three years ago, in the Migrating to Localhost article, I mentioned that I moved all of my private repositories to GitHub because, hey, it’s free for personal use and someone else gets to worry about keeping it running.

Few months ago, my Sony WH-1000-XM4 headphones started having issues where they would randomly produce high-pitch unbearable sound directly into my ear.

Introduction For the past few months, I’ve been on a journey of moving all of my self-hosted stuff into kubernetes in order to learn it better.

It has been almost an year since I finished my last project hosted on Azure so I thought it was time to experiment with it a bit and catch-up on “new” services I haven’t yet tried.

When I first heard of K8s few years back, storing persistent data on top of it was as forbidden topic, and something you shouldn’t really do.

This is a short function I crafted recently to create a new Hugo article from within the Emacs.

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?

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.

Over the years I have dabbled with Kubernetes on-and-off a bit, and mostly learned theoretical stuff surrounding it.

As you probably know, this website is based on an amazing static website generator Hugo.

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.

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 a sea of information, staying up-to-date with the latest news, blogs and updates can be an endless task.

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.

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.

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.

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.

My GPG setup consists of two Yubikey keys, each holding same set of keys in its internal storage.

Background I use GPG for encrypting various things locally on my machines.

Few months back, I’ve had around 30 thousand email messages in my mailbox.

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.

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.

Background Few months ago (less than 3), I’ve switched my website from Wordpress to Hugo .

You’ll be amazed how much things you can learn about the process on the Linux system by exploring and poking around /proc/.

BTRFS - the filesystem that was first introduced in 2009, back in the days of Linux 2.6.x kernel.

On the old Wordpress-powered site I have used “Koko Analytics” software for tracking some basic data about visitors of this blog.

You may have noticed that this site is a bit different in the past few days.

Hi there!

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.

Yesterday I decided to give Cinnamon a try on my main desktop.

I’ve noticed that for the past few months I have been using Emacs more and more, and I have tweaked it almost perfectly to my liking.

So I’ve started this wild wild OpenSUSE ride and already posted some initial impressions and gripes I had.

For the past few years I’ve been using Logitech MX Master 2s, and this mouse has been a real gem.

This is a short update on the progress of my OpenSUSE experiment.

As noted few days ago, I decided to give OpenSUSE another chance.

I’ve been trying OpenSUSE throughout the years, at least once or twice a year, and there was always some set of annoyances with it so I could never stay on it permanently.

My current email client of choice is Mu4e within Emacs.

Recently I purchased Samsung Galaxy Buds Live.

It has been mentioned in the comments of the older version of this article that the build process no longer works so I’ve decided, instead of updating old article, to write a new one.

In order to start with this article, I first had to define what the DevOps is.

For years I have been trying out various types of keyboards.

As an long delayed experiment, I installed Windows 10 on my machine and forced myself to use it and go through initial hurtles in order to give it fair chance, see where it stands today as opposed to few years ago when I’ve last tried it and in order to l…

Just like Bash on Linux, PowerShell on Windows has it’s PATH-like variable from which modules are being automatically loaded.

Setting up Wireguard based VPN is quite easy.

Seems to me that this my little trip to the Windows land might actually trigger me to learn a thing or two about that OS.
