Browser-Based HDD/SSD Health Analysis.
Hard drives report their health using a system called S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology). You can read this data using command line tools like smartctl, but the output is often hard to read. Manufacturers store data in raw hexadecimal values. A read error rate might look like 0x00000ab42 in a terminal. This could be zero errors, or it could be thousands, depending on how Seagate, WD, or Toshiba encoded the data. This viewer attempts to decode those raw manufacturer-specific values to tell you if a "high" number is actually bad, or if it is just a routine counter.

Fixes the crap Windows leaves behind.
You'd think that stuff would be over by now with sleek, modern OSes like Windows 11. Well... the built-in Windows cleaner might be enough, sure. But instead, the "modern OS" blesses us with a whole new batch of problems: ads in the Start menu, creepy data collection, and preinstalled junk apps you didn't ask for and can't easily remove. It's kind of wild that we still need tools like this in 2025. And they don't even sound that different - like this one here: CrapFixer. What can I say? The tech world is a bitch.

IVM (Incremental View Maintenance) implementation as a PostgreSQL extension
Incremental View Maintenance (IVM) is a way to make materialized views up-to-date in which only incremental changes are computed and applied on views rather than recomputing the contents from scratch as REFRESH MATERIALIZED VIEW does. IVM can update materialized views more efficiently than recomputation when only small parts of the view are changed.

Browser extension that automatically fills out cookie popups based on your preferences.
Most websites today want to process your data and ask for consent using cookie banners. While these banners are meant to give you control, in practice they often result in repetitive and time-consuming clicks—especially if your browser clears cookies when you close it. The same banner reappears, and you find yourself making the same choices again and again.
Consent-O-Matic is a browser extension designed to solve this problem. Developed by the Centre for Advanced Visualization and Interaction (CAVI) at Aarhus University, the tool automatically handles consent banners on your behalf. After you set your preferences during installation, Consent-O-Matic will recognize many common Consent Management Platform (CMP) banners, apply your choices, and confirm with a little checkmark next to the extension icon.
