Modello Player Piano – Arrived!

April 11th, 2017

Look what made it to my house!

Modello Player Piano

My Great-Grandmother bought this piano.  If I understand correctly, she bought it in the late 1930’s or early 1940’s.  It’s a Modello brand piano, with a pneumatic player that plays the paper rolls.  It was at my Grandparents’ house until the early 1980’s, when it moved to Mom and Dad’s, so my sister and I could have piano lessons.  In 2017 it moved to my house, so Mom and Dad could have the end of their rec room back.  My sister, who got way more out of those lessons than I did, lives in a tiny apartment she rents, and has no place to put a piano so it came here.  When she gets settled into a more permanent place, she and I will talk about where it goes.

PBP: 101 Reversing Scalars

June 15th, 2015

The PBP suggests that when you want to reverse a scalar, you explicitly state this with ‘scalar reverse $variable’ instead of just using reverse on it.  It suggests this both makes explicit, and regularizes the use, regardless of the context it is called in.

I don’t like this suggestion and don’t feel it is needed, but I won’t object to it because of the clear example in the book that makes it clear how it helps.  I find the demand you add a ‘scalar’ all the time because sometimes it’s unclear to be a problem.  I’ll probably turn off the critic warning for this, but I won’t say it’s too horrible.

Not only did I make all the arrangements in time, I made my flight and have found the hotel.  I am checked in and sitting in a room full of geeks having a hackathon.

It’s a room full of pretty serious computer users.  I am not the only one in the room who has configured UUCP, for example.

Fun so far!
