Exponentials still have the capacity to shock me. If mass wearing of masks make just 0.01 shift in the spread per day, from say 1.22x to 1.21x, there would now be ~20% fewer cases (and ~20% fewer deaths) in the UK since March 12. I had to double check that multiple times.

I want to thank Simon for his influence on my own work - again sometimes indirect - also for his limitless personal kindness, and everything he has brought to Microsoft. His charitable giving has been an inspiration to many, and he is a man of dignity.

From my perspective he has been a hugely valued asset to the company and it is deeply sad to have to say goodbye. I look forward to having him as a colleague in the world of open source and hope that our paths cross often. With greatest fondness and deepest respect Don

Just hit that part of a scrappy POC project where my pile of hard coded crap needs to turn into a beautiful, refactored parallel swan with CLI and docs etc. Refactoring in #fsharp is almost joyful. You break everything and type system just makes your todo list for you.
