I woke up this morning with an ominous feeling I may have to learn Scala 😱

My condolences, Thomas.. Hehe.. is it for some O'Reilly course thing?

@thomasnield go back to bed! and wake up from this nightmare

Read this post, then let's never talk about Scala again: http://stackoverflow.com/questions/7888944/what-do-all-of-scalas-symbolic-operators-mean

reading that post gives me a headache

@edvin @ron haha yeah, the Reactive Python for Data Science stuff seems to have caught fire with OReilly. If that does indeed go well with audiences, logically the next step is using RxScala with Spark. Dammit, why can't the data science community just use Kotlin? It works wonderfully with Spark.

@thomasnield It's always valuable to learn another language. Learning Scala for sure made me a better programmer. I didn't like it though, and will never choose to write anything in it.

@edvin oh Geez. Just looked at that post. Don't think it, don't say it. Don't think it, don't say it...

@edvin true, I may learn just enough to teach that class, like I did with Python. Thankfully it's on the JVM so it will be somewhat less alien than Python. But still, that syntax...

You normally don't need to use so much icky syntax yourself, but framework designers go overboard just because they can.

Nothing good comes from that.

I probably wouldn't choose to write anything in Python personally, I only use it for research. Kotlin is my go-to for everything now.

Engineer machismo 😱

Hehe 🙂 Golden Hammer ™️

I'm just more productive whenever I can stay within my favorite language, so I'd choose it even when there might be more suited alternatives as long as the drawbacks aren't too large.

Indeed, I think Kotlin could be used in data science and I need to keep pushing that grassroots campaign. Right now the only option is Python and Scala, there is no in-between in terms of accessibility/practicality

I don't see much value in developing both Scala and Kotlin skills (aside from someone directly paying you). Plus Java is becoming more functional itself

I think Python is better for the beginner because you can do simple things with just assignment and subroutine structured programming

@carlw yeah, I definitely don't plan on becoming a Scala guru, but it does help to have basic proficiency in several competing languages so you can objectively explain the merits and drawbacks of each one.

@thomasnield definitely...i try to structure the languages i support with as little overlap as possible. for example, I take consulting gigs on Java (desktop, server-side), Swift (Mac), PHP (Web). Someday Kotlin will get in the mix But i get a lot out of cross-referencing JavaFX with other UI toolkits

I'm not sure if Scala can do this, but I think being able to fallback on straight-up structured programming for a simple program in Kotlin is helpful for data science: a main, a few functions. That's probably how a data science algorithm is spec'd out rather than an object-oriented modeling, right?

results = runRegression(input)

I just noticed that there is something wrong with

setInScope(injectable, scope)

and

scope.set(injectable)

. Since we pass in instances, I can't be sure that I insert it at the correct type. I'm unsure if this can be fixed without requiring the type you want to inject it as actually. Checking now, but the bug is in 1.5.9 as well.

Puh, seems there is a way to solve this 🙂

Committed a fix 🙂

@edvin the

Fx.registerApplication

signature has changed. Does this change how an app is registered from a JavaFx application?

Is there an easy way to center-align items in a

bottom

of

borderpane

?

I tried this:

bottom {
                    text {
                        bind(vm.name)
                        style {
                            alignment = Pos.CENTER
                        }
                    }
                }

and also setting the style in

bottom

, but no luck.

nevermind, figured it out

@User uploaded a file: and commented: Now the question is how to hor-align the lower text with the gray area, regardless of how wide the other text is...
