Pathing.
- The CEO of MongoDB stepped down to spend time with his family. His resignation letter is absolutely touching and sincere, and shows the kind of courage and values that I can only hope to display myself.
- A great piece on the Amazon/Hachette fight.
- (Another) old and really fantastic Paul Graham essay, "How to Make Wealth."
- Proctor & Gamble is killing half of its brands.
- The ethics (and logistics) of quarantines.
Building.
- Using a crazy combination of sound waves to trap objects in mid air.
- A satellite was launched with a really high resolution camera - and the ability to map an area the size of Texas every day.
- Chobham armor - a secret mix of metal plates and a ceramic/metal matrix - is used on tanks like the M1 Abrams.
- Boeing is making jet biofuel from tobacco plants.
Logistics.
- Uber analyzes what happened when Boston's MBTA extended subway hours.
- There is a satellite graveyard in the South Pacific ocean.
- "Cold reading" is how psychics learn about their patients - and fake that they know more than they do.
- The working principles we use at Undercurrent.
Reflecting.
- The ISEE-3 reboot project's excellent WebGL/video site explains how the project developed and where the satellite is now. <<= Really cool.
- An insider account of how Yahoo partnered with Alibaba.
- Some data on the recent plummet in auto theft.
- Why Facebook became so popular early on.
Stuff that doesn't fit into my dumb/arbitrary categories.
- A great LanguageLog post about a menu item translated as "I can't find on Google but it's delicious."
- George Boolos' classic, "Gödel's Second Incompleteness Theorem
Explained in Words of One Syllable." <<= Super nerdy & worth having read at some point in your life.
And.
How the LED displays powering Times Square work.

Love, Spencer.
ps - Thank you to everyone - especially my friends at Gin Lane, Undercurrent, and on twitter - who referred me to everything here.
We should be closer friends. Coffee's on me.
