Abandoned States: Places In Idyllic 1960s Postcards Have Transformed Into Scenes Of Abandonment

Fascinating to look at: Pablo Iglesias Maurer revisited public places like swimming pools and restaurants depicted on postcards and matchbooks from the 1960s that are abandoned today and made animated GIFs from the photo transitions.

Labor not as one who is wretched, nor yet as one who would be pitied or admired; but direct your will to one thing only: to act or not to act as social reason requires.

Associated Press says it will avoid the term "alt-right" in the future because it's often "a euphemism to disguise racist aims":


Kill Process or How I discovered the IndieWeb (finally)

2 min read

Of course I have heard of the  paradigm before. But for some reason I never bothered to really dive into it. Until a few days ago, when I decided I want my personal presence on the web to be IndieWeb-style from now on.

How came that? Partly because I'm currently reading the book Kill Process by William Hertling. It's about murder, privacy, hacking, high tech surveillance and data mining. The book is great and I can recommend it to everybody who likes tech thrillers. Hertling gets the technical background and hacker stuff of the story really good together. Angie, the heroine, works at Tomo, the largest and quasi-monopoly Facebook-like social network as a database programmer. Part of the story is her ambition to create an alternative to the centralized privacy nightmare the Tomo service became. So she decides to do something about it and plans to build a distributed, federated social network of networks. She also meets and joins with people familiar with the IndieWeb concept. That's when I was reminded of how good the idea really is.

I had a simple personal site running on the Grav database-less content-management system. Grav is nice because you can have a Git-based deployment process relying totally on the actual (Markdown) files - since there is zero configuration in the database. It would not have been too complicated to enhance my old site with IndieWeb attributes and protocols but anyway I was excited to discover the fantastic Known CMS this site is now running on. I'm very happy with it, thanks to all of you involved in the development.

If you want to find out more about the IndieWeb, I can recommend An Introduction to the IndieWeb by Chris Aldrich.

This diagram illustrates the correlation of observed global mean temperature with increasing CO2 and changes in the number of sun spots. The green line shows CO2 concentration based on ice core measures, whereas the blue line depicts actual measurements from the atmosphere.

Hard to ignore that we might have a trend here.

Amsterdam 1978 vs. 2015, with and without cars

Amsterdam hasn't always been the bike-friendly city it is now famous for. A city has to commit to or else it won't happen by itself.
