Pretty Good Hat

It’s that most rare and special of mornings in Flagstaff, where it’s full-on foggy out and it feels like waking up on the San Juan Islands.

I’m officially on vacation, but there’s so much that I want to “bring back” to work with me from this week’s rstudio::conf. Looking forward to one more day with this community of folks doing and learning things.

Two windows from the RStudio profvis tool, showing the times of several procesess. The second window shows the same process being completed dramatically more quickly than the first.

I used the RStudio tool profvis this weekend to find speed improvement opportunities in Armorer. I suspected that I could rewrite a big operation that calculates the maximum of many columns across several thousand rows. Holy smokes: Using matrixStats::rowMaxs cuts processing time by an amazing amount!

I finished a big update to Armorer this week, to enable inclusion of subclass fragments in stat calculations. I learned a ton with this release and laid good groundwork for additional mod management. I’m pretty pleased!

Somewhere in south-central Utah, listening to this episode of Waypoint Radio, my wife said, “Hmm, Motorsport Manager sounds pretty neat.” She, who rarely plays video games at all, turns out to be an absolute star at it. (No surprise, of course; she is an extraordinary manager of many things.) We had a great time learning and playing it yesterday. What will happen to our ex-driver turned manager, Han Portlandia, and her scrappy young team? We’ll find out more today!

I’m happy to have improved some R code today using group_split, replacing my prior method of cycling through a data frame to build several new subsets. I’m not sure it’s more efficient given the size of the data set, but it sure reads more nicely.
