Email Reputation: Separate Use-Cases on Subdomains

CSS by T. Afif @css-only.dev · 28/05/2026
What about a straight line that bends when the circles get closer and stretches when they get farther. It's surely not possible using pure CSS, right? Right!? 👀 css-tip.com/bending-line/ Probably my new favorite demo, powered by the modern features. CSS is awesome! 😍

The battlefield has changed. New CVEs emerge weekly and it is really hard to keep up the pace. To improve the process, we did setup renovate in the backend which automatically creates merge requests with updates for patch versions on a regular base. How do you keep up the pace?

Divide and Conquer: Beware of the Mega Merge Request Madness Large merge requests are impossible to review thoroughly — they cause context overload, review fatigue, and rubber-stamp approvals.

As an OSS maintainer, my new rule is that anything a frontier model can find with some reasonable effort is a 0-day. Hence why I'm now shipping security releases on public holidays.

#reverseEngineering is fun! Some years ago working at an online ticketing platform, we wanted to have our own turnstile. But the one we bought was not as easy to integrate as promised.

"Caps that remain on the plastic bottle is a constructed problem by the EU!!111". No it is not. At 100 meter of beach at the North Sea, alone 40 caps have been found. Yeah it sucks - but plastic in the ocean sucks even more. Source: mcc.jrc.ec.europa.eu/documents/Ma...

A (beer) glass level indicator powered by a NodeMCU and an ultra sonic sensor. A fun project my neighbour is building with his colleagues for a colleague who is retiring soon where I am contributing the code.
