  • Crime rates dropping in US, multiple companies working with NASA for ISS access, direct observation of gravitational waves, left reddit for Lemmy, multiple COVID vaccines in like a year from outbreak, more usage of renewable energy sources, etc. There are some obvious problems we need to get together and address as communities, countries, and species, but there are a bunch of improvements and advancements being made too.





  • I like adding a backup function to .profile that can take a file or list of files as an argument and make a copy with a date suffix on the file name, and same date additional backups just add a character like ~ at the end. It’s in version control, but if I’m testing a change it’s just faster to restore the file from a copy in the same place.












  • In space sciences coming up are new manned Moon missions followed hopefully by some Mars missions. Also LISA is a huge interferometer that is planned to be deployed in orbit by ESA around 2035. Different size interferometers can measure different wavelengths of gravitational waves. LIGO (the interferometer observatory already in action measuring black hole collisions) has arms 4km long and can measure wavelengths in the range of 7Khz-30hz. LISA will have arms 2.5 million km long in orbit around the sun and is expected to be able to measure much much smaller waves.
