Abandoned homes

'Ghost Houses' Haunt a Rapidly Aging Japan - Atlas Obscura

As a town’s older residents move to assisted living facilities or die, their homes pass down to their heirs. Younger generations, now increasingly located in Japan’s major cities, often have no interest in inheriting or maintaining the family’s ancestral home deep in the countryside, beyond paying the required property taxes. In other cases, officials are unable to locate or identify the proper heirs, leaving the fate of the property in a state of limbo.

A demo for the Commodore 1541 disk drive itself. A little hardware hacking to connect it to a monitor and you only need a C64 to bootstrap!

In case you don't have a C64 setup laying about, here's a video of the demo playing on real hardware.

Faster planet, shorter days

Shorter Days as Earth's Rotation Speeds Up

2020 was the fastest year over the past six decades, and 2021 is expected to be even faster, with an average day being more than 0.2 milliseconds short of the standard 84,600 seconds.


Variation of daylength throughout 2020. The length of day is shown as the difference in milliseconds (ms) between the Earth's rotation and 86,400 seconds. (timeanddate.com)

The Earth has been spinning faster lately

Coordinated Universal Time - Wikipedia

Long story short, UTC is an attempt to keep pace with sidereal time (i.e. based on position of celestial objects at a certain time of day) using SI seconds (i.e. a fixed number of caesium-133 transitions). This is why we have leap seconds.

What causes changes in Earth's rotation speed?

It's all about conservation of angular momentum.

Anything that changes Earth's mass distribution affects the speed at which Earth rotates on its axis. These include:

  • Tidal effects
  • Post-glacial rebound
  • Tectonics and seismic effects
    • Earthquakes in short term
    • Continental drift in long term
  • Mantle dynamics
