Which email provider handles your municipality's official communications?

We built mxmap.nl to make that visible, all Dutch municipalities, mapped by email provider based on public DNS records.
Inspired by the Swiss original mxmap.ch by David Huser. We adapted it for the Netherlands. All credit for the concept goes to him.

Under the CLOUD Act, provider location matters. The map makes the current reality clear.

i was quite surprised to discover that no one had registered deleteduser [dot] com, and was curious to see how many emails i'd get if i registered it, assuming many orgs 'delete' logic probably just overwrote the email address with [email protected] or similar.

The answer, is at least 3 different orgs in the hour that I've owned that domain and been listening for email.

And yes, all of those emails contain the actual PII of the person who has been 'deleted' :-D

Ok, fellow hackers, I propose a pact: That new EU age verification app thingy ... do NOT help improve it.

Don't publish findings. Don't responsibly disclose insecurities. Don't facilitate them making it bulletproof.

If personal data is directly at risk, by all means, slam their asses into the ground. GDPR them into oblivion.

But on its core functionality this needs to be, to become, and to stay, the most insecure, the most easily circumventable piece of shit code on the planet.

I have never been more offended by a website's typography. Sent me directly into #ADHD overdrive, and wondering what this does to people with dyslexia. Screenreaders should be fine, but still, wrapping every single word through JS in a span is nasty.

Responsive images are tough and often implemented incorrectly. With sizes=auto the browser will figure things out.

Chromium supports it, Firefox 150 in two weeks, Webkit in tech preview. I can't wait for this!

map.getOrInsertComputed is newly baseline! It's a small feature, but I've found it pretty useful. Here's how it works.

Tales from beyond the Fedi bubble:

Yesterday our keynote speaker was a “strategic futurist” so yes of course they talked about AI for 45 minutes. During a conversation at my table, people shared how they use AI and I asked one person, who was using it to summarize social chatter on the internet about certain topics, how you can vet the information given. At first I think she felt defensive, but as she talked through it you could see a realization like oh shit I really can’t.

Then toward the end of the day we had to fill out a form for compliance reporting (pharma has to report if they gave me food) and since I’m a licensed healthcare provider I have to report my NPI number (national provider identifier). I don’t have that memorized so I googled it, something I’ve done for years to quickly find it, and the AI summary said there was no information linking my full name and degree to an NPI. But if I scrolled past the summary the first website preview listed my NPI.

So I showed the woman next to me like hey here’s an example of how AI gets it completely wrong. She was floored.

It’s bad out there, folks.
