Maurycy's blog
Maurycy — Electronics enthusiast and amateur astronomer
Technical deep-dives on systems programming and software engineering.
maurycyz.comA genuinely eclectic technical blog covering electronics teardowns, astrophotography, web development, and the case for owning your own space on the internet. Maurycy builds his own tools, photographs deep-sky objects, monitors ionizing radiation, and writes about all of it with the matter-of-fact detail of someone who finds no meaningful boundary between these interests. The blog itself is a statement: no ads, no algorithms, no AI training permitted — just human-written posts on a personal website.

Be careful with LLM "Agents"
I get it: Large Language Models are interesting... but you should not give "Agentic AI" access to your computer, accounts or wallet. To do away with the hype: "AI Agents" are just LLMs with shell access, and at it's core an LLM is a weighted random number generator. You have no idea what it will do It could post your credit card number on social media. This isn't a theoretical concern. There are multiple cases of LLMs wiping people's computers [1] [2], cloud accounts [3], and even causin...
Inside an alpha-beta scintillator:
Just a heads up: this post is incomplete. However, it may be a while before I am able to finish it. I am publishing it early in hopes that you will still find it somewhat interesting. I've recently acquired this tiny contamination monitor: Just 4 cm wide! It's more sensitive then a Ludlum 44-9 despite being smaller then it's pancake style G-M tube. After removing four hex screws, the AlphaHound easily comes apart: Oooo This is very nice: Many similarly sized devices are difficult or...
Notes on blog future-proofing
One of the great things about web pages is that they are long-lived and mutable. There's no need to aim for perfection on the first draft: A page can continue to be improved for years after its original publication. However, this mutability comes at a cost: DO NOT POWER [IT] DOWN!! — The first web server. Servers are just computers: If they ever break or are turned off, the web site vanishes off the internet. h-n {color: #F27; font-family: monospace; background-color: #111;} h-v...
Writing my own static site generator
In principle, a static site generator is a good idea: They automatically populate your homepage, index pages and RSS feeds. Unlike software like Wordpress, they don't add runtime cost or security vulnerab­ilities: They run once and are never exposed to the internet. However, they all put weird restrictions on how you structure your site: Nearly all of them require you to write in Markdown, which is common, but poorly specified and difficult to parse. As soon as you do anything more comp...
How to write your own website
I recently wrote an essay on why you should set up a personal website rather then using social media. Doing so lets you own your space on the internet, customize it and free your readers from constant advertising and algorithmic feeds designed to keep you stuck doomscrolling all day. Despite how much time we spend using it, creating something for the intenet is seen as arcane wizardy by most people. This is a fairly accessable guide to getting started. You'll need a text editor (any will do)...
