knute··on The great Pacific garbage patch is largely abandoned fishing gear
I have a theory that buying landfills (especially older landfills from before the popularization of recycling) is a good very long term investment.
knute··on Grammarly shared its tokens with all websites
It seems like it would be more fair for the headline to use the past tense.

knute··on Flow and TypeScript
As a professional web developer who uses TypeScript (disclaimer: MS employee, not on the TypeScript team), I don't find that it impacts in-browser debugging. TypeScript has the ability to generate map files, but we don't use it because issues with our tooling. I don't miss it though, because the generated JavaScript is pretty close to the TypeScript (we target ES5, if you can target ES6 the mangling is even less). Once you learn the common patterns (methods get mapped onto the prototype, fat arrow functions get compiled to regular functions with a _this variable) it's pretty straightforward to debug in the browser.

The dev inner loop is maybe a little slower with the compile step for us, but it is possible to use TypeScript's automatic compilation with webpack and Node and all the latest hotness and get automatic build/deploy/refresh (see Office Fabric: https://github.com/OfficeDev/office-ui-fabric-react)

knute··on 24/192 Music Downloads Are Very Silly Indeed (2012)
I had satellite radio for a while but had to cancel it because I couldn't stand the sound of cymbals at whatever bitrate they encode at. Weirdly, when the phone operator asked why I was cancelling and I told him "audio quality" he acted like he had never heard that before.
knute··on A330 flight control laws saved Voyager, inquiry finds
The outside of the airplane has a forward-pointing tube called a pitot tube. As the airplane travels forward, air is compressed into this tube. By measuring the pressure, you can derive the airspeed. However the higher you go, the lower the ambient air pressure is and so the "indicated airspeed" is not at all accurate.

However indicated airspeed is still very useful as it measures the air resistance the aircraft is encountering which determines lift and airframe stresses (which is why the airframe speed limit is in indicated airspeed and not actual airspeed).
