How many things in space have ever been repaired? I count four: Apollo 13, Solar Max, the Hubble, and the ISS. Any I've missed?

I'm signing my first term sheet of the year today, and noticing how small the option pool is. When you need fewer employees due to AI, you can give each of them a bigger ISO package but still have less dilution.

They are right to be excited. I had a delayed flight from MIA to IAD on July 4, 2006, and happened to be in the air west of Cape Canaveral at the moment Discovery launched. A once in a lifetime thing to see!

The same CEO told me that a customer demanded an on prem version of his product. His CTO said a year ago, they would have had to hire an engineer to deliver that request. Now they just burned some extra tokens for a few months.

A portfolio company just reported to me how they completed a massive backend code migration in 20% of the time it would have taken without Claude Code.
