@kastork yes please do! Keep in mind I made those primarily for Python devs and teach some basic language features of Kotlin. I do cover several modeling examples in the last section or two, as well as libraries.

@thomasnield most of the people here doing OR and data science are using R or Python, so it will be a good perspective.

In that case, I think you'll find it useful. Definitely share it with Python/R colleagues to make Kotlin accessible quickly.

Linear/Integer programming is something I will probably cover heavily at this session. Scheduling problems seem to have gotten a lot of interest, not just from me but from attendees/viewers of my last talk. https://github.com/thomasnield/optimized-scheduling-demo

I'm in the position of needing to package data science workflows in desktop apps -- so all the stuff you've been talking about lately is very interesting to me.

It is funny, when I was getting my OR degree, the discipline was on the decline as far as companies having "OR Departments." Now everyone has an OR department again, they just call it the Data Science department.

@kastork yeah there's a lot of valuable libraries already in existence for the JVM. I think Kotlin will take off hard for mathematical libraries once Kotlin/Native comes out.

@kastork lol, I actually work on a team titled "Operations Research/Data Science"

I don't know if you saw this article I wrote recently. I'd be in favor of going back to calling it "operations research": http://tomstechnicalblog.blogspot.com/2018/01/is-it-time-to-stop-using-term-data.html

Ah, yes... I've seen this before -- I should really circulate it around my community

This morning, I plugged in the latest snapshot with the app lifecycle fixes by @edvin into my project, and now my test is passing. Thanks again for the quick fixes!

I had a company demo for this week, and they gave me less than a week to make it lol

Sorry for being so quiet lately. I'm prioritizing my production endeavors, right now but I try to keep everything flowing while I get set up with the keyboard business 🙂

Come back! The analog world is overrated.

That's what I thought 🙂 But I try to make it as digital as possible!

Question on nullability and hashmaps/models:

amanda.hinchman-dominguez

02/03/2018, 8:32 PM

I've created a set of modules in a hashmap, and once I've detected a tile's title, I want to refer to the hashmap to refer to the stored properties of the tile, stored as

moduleBuilder

amanda.hinchman-dominguez

02/03/2018, 8:33 PM

If the code knows that the title does exist as a key, why would it consider the value

moduleBuilder

as nullable?

edvin

02/03/2018, 8:35 PM

@amanda.hinchman-dominguez The code doesn't know that there is a key for it, just because you added it earlier. This is not information that is available to the compiler. Sorry if I misunderstood you.

@edvin oh no, I think that answers the question
