I've spent the last few months rebuilding my quant workflow after returning from fourteen years in software product engineering. The hardest part wasn't the math (for me). It was learning when to stop: when to kill a hypothesis and move on. I wrote up the funnel and mental model, from terminal exploration through statistical validation to robustness testing.

I'm really excited that my assert_matches!() macro is finally stable. I can't believe it's been five years since I added it to (unstable) Rust. Time flies. https://github.com/rust-lang/rust/pull/82770

‪This year's @scaladays
is accepting 2 hour workshop proposals, in addition to the more usual 30 minute talks.

I'm thinking a workshop on building terminal apps using Scala Native could be fun. What do you think? What workshops would you like to see at the conference?

In general, I love this idea. Conferences are still based around 19th century ideas that we have to have 1 person talking to N people. With technology we can make things much more interactive. It's more work though, and a workshop takes the space of 4 talks, so it has to be worth doing.

Also, we're running an event this evening to help shape proposals, so come along if you need some help getting your proposal ready: https://www.meetup.com/london-scala/events/314859429/

As a committee member I'm gonna say that >90% of the current proposals could use some very basic improvements.
