When I got out of the bus (I was the only passenger), the shear vertical walls of mount Radlefshorn, still cloaked in dense forest at this height, already waited for me. https://lukasleuba.ch/server-log/ Sun, 11 Jan 2026 00:00:00 +0100 https://lukasleuba.ch/server-log/ I recently moved to a new apartment. First things first, of course I had to setup a new homelab. More compute, more space, better networking. Initially I planned on buying the performant ‘Minisforum MS-01’. However, ram-prices have since skyrocketed and I could not justify the cost of this setup. Instead, I looked on the second hand market and found the following: Proxmox Server Setup HP Prodesk 600 G5 8 x Intel(R) Core(TM) i7-9700 CPU 32 GB Memory 1 TB nvme (~ CHF 400) Additionally I will install the two SSDs from my old server: https://lukasleuba.ch/now/ Sun, 11 Jan 2026 00:00:00 +0100 https://lukasleuba.ch/now/ getting my motorcycle licence I bought a used Sym Cruisym 300i for getting around and to work. I didn’t expect to have so much fun on such a small scooter - and its practical as well. I’m reall glad I went for it. Anyway, since its ‘bigger’ than 125cc, I will have to do the motorcycle exam in the spring, so wish me luck. my scoot !

It will be hopefully updated with every hike I undertake. It is mainly meant as a reference for me, but it maybe useful to you as well. 25l Backpack watertight packing-bags merino trekking socks normal socks merino trekking underpants 2 pairs of normal underpants merino t-shirt normal t-shirt fleece windbreaker jacket rainjacket hut-shoes / barefoot shoes suitable hiking shoes (alpine boots, light boots, trailrunners, barefoot boots…) light or heavy crampons light, small towel buff light gloves hat sun glasses binoculars hand sanitizer toiletry-kit (toothbrush/-paste, showergel, deo) tissues sunscreen 2 bottles (maybe one waterfilter, one thermos) survival tin powerbank flashlight smartphone + cable / powerbrick pocket knife some cord physical card or trekking-guide adequate food chewing gum Example Layout for the ‘Tour des Dents-du-Midi’ https://lukasleuba.ch/bsc/ Sun, 20 Jul 2025 00:00:00 +0200 https://lukasleuba.ch/bsc/ On the 7th of July 2025 I finally finished my BSc-thesis and with this my bachelors degree. The thesis investigates if and how a certain kind of cryptographic signature scheme - the BBS signature scheme - can improve privacy in digital identity systems such as the Swiss E-ID. Here is the abstract: Abstract The digital transformation of identity systems holds the potential of making identification not only more convenient, but also more secure and privacy-respecting. https://lukasleuba.ch/rote/ Mon, 09 Jun 2025 00:00:00 +0200 https://lukasleuba.ch/rote/ For an upcoming exam I need to memorize a lot of genus and species names. Normally I would have written down each question/answer pair by hand and learn like this. However, on this occasion I had neither the time nor the will to take this approach. Instead I teamed up with AI (for speed) and drafted a little python script which (1) searches for quiz files in the working directory (2) lets you choose which files you want to go through (3) goes randomly through the questions of the files you chose in step 2. https://lukasleuba.ch/uses/ Sat, 22 Mar 2025 00:00:00 +0100 https://lukasleuba.ch/uses/ Operating Systems & Environment I use Debian 13 as my daily driver OS. I use kde as my DE. I use OpenBSD as OS of choice for my Server (VPS). I use Vultr for hosting the VPS and I use Hostpoint for administering my domains. I use Proxmox as OS on my NAS. Development & Tools I use Hugo to generate this site from md-files. I use kitty as terminal emulator of choice. https://lukasleuba.ch/neutral/ Sun, 24 Nov 2024 00:00:00 +0100 https://lukasleuba.ch/neutral/ Why is there (so much) biodiversity? This is a good question. Why are there so many similar species in a homogenous environment such as trees in a tropical rainforest? This is an even better question, and one which was probably asked by every ecologist since the beginning of ecology. The neutral theory of ecology is not actually about answering these questions. Rather, it is about preventing the existing hypotheses from being fooled by randomness. https://lukasleuba.ch/comments/ Thu, 24 Oct 2024 00:00:00 +0200 https://lukasleuba.ch/comments/ As you may have noticed, my website is heavily inspired by Derek Sivers. On his site, he has a comment section under every post which he implemented himself using PostgreSQL and Ruby. I always found this feature really cool, but couldn't get myself to do the work and implement it on my server as well - until now. I decided to "sit together" with claude.ai and implement my own comment section. https://lukasleuba.ch/easyEmacs/ Sun, 31 Mar 2024 00:00:00 +0100 https://lukasleuba.ch/easyEmacs/ If you are not using a rolling release distro, it can sometimes be frustrating to depend on more or less outdated software. Mostly, I don't care about the newest and shiniest thing. I could not care less if I use this or that version of libreoffice. But sometimes it can be nice to use something newer. In my case, I use the emacs text editor (doom) a lot. The version available with apt is 27. https://lukasleuba.ch/howToWebsite/ Sun, 01 Jan 2023 00:00:00 +0100 https://lukasleuba.ch/howToWebsite/ ⚠️ This post is no longer current. I switched to using md-files and generating the site with HUGO. The HTML files which make up this site were automatically generated by EMACS Org-Mode's publishing function. As a total beginner with Emacs I wanted to share my struggle creating this website so other people - maybe you - can learn from my mistakes. Why use ORG-Mode? Today there are a lot of (easy) ways getting your Website online. https://lukasleuba.ch/about/ Mon, 01 Jan 0001 00:00:00 +0000 https://lukasleuba.ch/about/ I like well-designed systems, tools, and objects that are durable, understandable, maintainable, and built with care. experience System Architect at the Institute of Virology and Immunology 2026 Professional After starting an internship at IVI in 2025, I joined the institute full-time as a system architect in 2026.

See my Now page for what I am currently reading. The recommendability score indicates how much I would recommend a book to the average person. This is not necessarily a measure of how much I liked it. The rating measures how much I liked the book.
