I wrote something on control theory and feedback loops in Kubernetes. I’ll start from scratch and gradually build up feedback loops that are self-healing and resilient, capable of scaling thousands of databases. Highly recommended to read. Check it out: planetscale.com/blog/the-fee...

Just installed my latest homelab equipment, the UNAS Pro from @ubiquiti.bsky.social. Currently have a simple Raid 5 setup. Will use it for Time Machine Backups and Personal Data.

Just migrated from hrsh7th/nvim-cmp to saghen/blink.cmp. It's definitely faster, and my settings have also reduced. While doing it, I also discovered that nvim no longer needs a comment plugin; it has a built-in commenting starting with v0.10. github.com/fatih/dotfil...

I went for a week to Billund, Denmark with the family. It's the home of LEGO. Because I shoot a lot of photos and people also ask me how it went, I wrote a lengthy blog post. Check it out: arslan.io/2025/08/30/a...

@arslan.io just wanted to say, amazing work on this one: arslan.io/halcyon-elor...

Quitting programming as a career right now because of LLMs would be like quitting carpentry as a career thanks to the invention of the table saw.

Latest version of my Elora split keyboard case.

Working on some prototypes to create a case with an integrated wrist pad for my new Halcyon Elora split keyboard. Here is one of the first examples.

Here is my latest blog post about my initial impressions with the Fujifilm X half camera. But TL;DR: I only recommend this for families with kids in mind. It's not a serious camera and shouldn't be treated like that. Check out the blog post: arslan.io/2025/06/14/f...

It's almost finished and I plan to publish it today. Subscribe to get notified once it's out: arslan.io

That’s a very good point I hadn’t thought about.

I added my latest design, the Concept2 BikerErg phone holder to my website. As you know, almost all of my designs are free , you can download and 3D print them. To checkout all my other designs, visit my works page: arslan.io/works/

dark-mode that follows macos system settings for terminal, tmux and nvim post from @arslan.io arslan.io/2025/06/06/a...

I went over my Terminal setup and revisited the setup for automatic theme switching. The setup has less moving parts and a lot of simpler compared to my old setup. You can see how Ghostty, Tmux and NeoVim all change automatically. I also wrote a blog post, check it out: arslan.io/2025/06/06/a...

The Last of Us TV show is a prime example of directors assuming their audience can’t understand complex narratives and dumbing down everything. They even transformed a smart character, Ellie, into a dumb girl. The writers made this show bad, not the actors. I’m done watching it.

A game where you try to MFA out your way entering rooms, but it resets every day after a certain steps. (yes I played to much Blue Prince, and yes I don't like constantly authenticating)

I recently added another lamp to my collection—the Tizio Micro, designed by the legendary Richard Sapper. He’s also known for his ThinkPad designs. A distinctive feature of his work is the incorporation of a red accent. You can see it here as well.

Finally received my new Kinesi Advantage 360 Pro's. You can now order custom white-painted ones (called Signature Series). A lot of things have changed since I sold my old keyboard; for example, it works now with ZMK Studio out of the box.

One of my favorite moments in London was attending an tour for the Barbican. Highly recommend for anyone into brutalism and architecture.

If you're a tax accountant in Germany and know what the following words mean Carta, Gumroad, LemonSqueezy, Contractor, ISO, NSO, stock option, exercise window, Deel, Remote, Merchant of Record, Delaware company you can make a lot of money. Sadly, I don't think you exist.

I’ve got a few dozens of books to read, but these two piqued my interest the most. Both were hard to find, luckily they started re-printing the The Interface. The book “Thinking Tools” was part of an exhibition in Frankfurt, and had to get it second hand from someone in Germany.

TIL that Erik Spiekermann has an extensive collection of vintage Braun Hi-Fi devices. (From the book “Braun Erleben”).

Someone shared this on Reddit, it made my day. Also the photos are dope!

I recently designed a small phone holder for the Concept2 BikeErg. Typically, I use an iPad while biking on it, but my iPhone is always connected to the PM5. This tray makes it convenient to keep my iPhone nearby. You can download the 3D model from here: makerworld.com/en/models/13...

I love this minimalistic screensaver watch. Got it from bauhausclock.com

⭐️ I wrote a post about managing friction, what it means and how you can use it to shape your life (that's at least how I did it for myself). Check it out: arslan.io/2025/04/08/m...

I'm planning to visit London for the first time and looking for suggestions for places that might be in my alley. As an example I plan to visit the Barbican and Southbank Centre for their Brutalist architecture. Any recs similar to these places are welcome (food, shops, etc..)
