March 15, 2021 - There's been a coup. We are no longer doing Kotlin. The insurgents have declared Scala as our new overlord (In these reading groups, we are flexible and go with where the energy is)
We are switching over to the book - Programming in Scala, 5th edition by Martin Odersky, Lex Spoon, Bill Venners, and Frank Sommers
March 1, 2021 - We all lead busy lives outside of this, so flexibility is important. Tonight we’ve adopted two proposals. 1) Let’s stagger the weeks so that we cover the readings one week and then go through the exercises the following week. If we need to take two weeks on the readings, then we’ll go through the exercises on the third week. 2) On days where we don’t have a quorum because of work pressure (life happens), let’s do a skip-week. Today is our first skip-week – one of us has a release tomorrow and another has a broken test that he’s fixing.
