Links to things that I found interesting but didn't want to do a full post about.

• Traces of Giant, 2,700-Year-Old Solar Storm Detected in Greenland Ice
• Acoustic meta-material: a shape that reflects sound but passes light and air. This is an interesting new technology with many applications.
• The "tragedy of the commons" is a right-wing lie. What you've been taught in school about it is probably wrong.
• 8 useful CSS tricks: Parallax images, sticky footers and more. These are moderately advanced techniques. 
• 5 Lightweight Gmail Tools That Solve a Few Pesky Problems. Rename headers might be the most useful item here.
• 15 New Features We've Already Spotted in the Android Q Beta. Lots of incremental tweaks.
