It's too common that open source developers don't get the appreciation they deserve for what can be thankless work. So, firstly, thank you for your work on Julia!

Question: years ago, it felt like Julia was on a warpath to take on R and Python as the language to use for data science. It feels like that momentum has slowed lately. Do you agree and, if so, what do you think needs to happen to rekindle that enthusiasm?

Why does speeding over speed bumps seem like they impact the car less than driving over them at a slower rate?

Ex physics guy speaking. There are some nice differential equations that explain this phenomenon, but the non-math explanation is that it has to do with the timescale over which the bump is applied. Look at the two limiting cases: at 0.000001 MPH, your shocks don't compress at all and you experience the full rise of the speed bump. At very fast speeds, the impulse to the shocks is so large that the shocks don't decompress fast enough before the wheel is off the bump and back on smooth ground.

I am simplifying the explanation (the answer depends on the precise speed, spring constants, and speed bump profile). There are also other effects that come into play. For example, if you go too fast over a bump you can start to bottom out afterward because your front shocks are compressed when you leave the bump.
