Linux, from before the war…

Seth Kenlon from RedHat has been finding old Linux distros from before the war and installed them. How bad is this old shit, from todays POV?

Slackware 1.01 (1993): It does not even have package management. But:

Over all, Slackware 1.01 feels a lot like a fairly modern UNIX—or more appropriately, it feels like modern UNIX might feel to a Linux user. Most everything is familiar, but there are differences here and there. Not nearly as much a difference as you might expect from an operating system released in 1993!

And it continues like that – much of the old stuff works and feels a lot like stuff today. So besides systemd, there has hardly been any progress at all.

For example, some people’s desktop looks like this, even today:

SUSE 5.1 (1998) – I know people how are using a desktop that looks like this, even today.

Vattenfall electrifies their own cars

Vattenfall is letting us know (article in german), that they will be chaning their fleet to electric drive – all in all 3500 cars.

Makes a lot of sense if you are in the business of producing electricity. They also will build chargers, they say.

They quote 1700 cars in Sweden, 1100 in Germany and 750 in the Netherlands, to be converted within the coming 5 years.

Vattenfall hat im Januar 2017 mit der über fünf Jahre geplanten schrittweisen Umstellung seines Fuhrparks mit 1700 Fahrzeugen in Schweden, 1100 in Deutschland und 750 in den Niederlanden begonnen. Dies umfasst alle Fahrzeugtypen vom PKW bis zu Technik- und Wartungsfahrzeugen. Die Entwicklung des Marktes für Elektroautos und speziell für leichte E-Nutzfahrzeuge wird für das Erreichen dieses Ziels entscheidend sein.

Fast and forceful gel robots

[These] robots are made entirely of hydrogel — a tough, rubbery, nearly transparent material that’s composed mostly of water. Each robot is an assemblage of hollow, precisely designed hydrogel structures, connected to rubbery tubes. When the researchers pump water into the hydrogel robots, the structures quickly inflate in orientations that enable the bots to curl up or stretch out.

Maya empire remains

Lidar Image

Two articles about the Maya civilization:

Seeker article about LiDAR being used to reveal ancient structures on the Jungle ground: A network of 150km of prehistoric Autobahn ran through the Jungle, binding the Mayan Empire together.

“These causeways are 130 feet wide, up to 20 feet high and in some cases they extend as far as 25 miles,” Hansen said.

A causeway is a raised road across difficult, often wet or unstable ground. Because of the raised structure LiDAR can find these roads even today.
