- Wärmepumpen funktionieren auch im Altbau. Eine zusätzliche Dämmung ist meistens nicht nötig, entscheidend ist die Einzelfallbetrachtung.
- Beratung durch Fachleute ist wichtig. Eine Heizlastberechnung klärt, ob Heizkörper getauscht werden müssen, weil bei geringerer […]

A few days ago, a client’s data center "vanished" overnight. My monitoring showed that all devices were unreachable. Not even the ISP routers responded, so I assumed a sudden connectivity drop. The strange part? Not even via 4G.

My niece comes to the U.S. most years from Europe to visit her grandfather.

This year she was stopped at the airport, taken into an interrogation room, accused of being a prostitute, had her phone taken and scanned, and released.

A beginner’s guide to Mastodon, the open source Twitter alternative
Unless if you’re really in the know about nascent platforms, you probably didn’t know what Mastodon was until Elon Musk bought Twitter and renamed it X. In the initial aftermath of the acquisition, as users fretted over what direction Twitter would take, millions of users hopped over to Mastodon, a fellow microblogging site. As time […]

Unhook ourselves from oil and gas and we unhook ourselves from dependency on dictators, autocrats and expansionist regimes all over the planet.
Renewables and other low-carbon energy sources are not just good climate sense. They are also good political sense.

In 1980 the United States led a boycott of the Olympic games in Moscow due to the Soviet Union's invasion of Afghanistan. Sixty countries joined the boycott.

The 2026 World Cup is mostly in the United States.

Whatever you might think of Maduro, the seizure and kidnapping of a head of state takes us to a very dark place. Vast, arbitrary, extra-legal power, which could be exercised almost anywhere, regardless of the character of the target government.
