The image quality and detail level, presumably from the RAW decoder, is pretty poor compared to Lightroom, CaptureOne etc. The last time I gave it a try was about a year ago though.
> I wonder why Kotlin beat Scala in this virtual programming language traction game.
The article shows google search traffic for Kotlin which temporarily spiked above Scala in the wake of the Android announcement and then dropped back down to less than half the Scala traffic, below Groovy in fact. I'm not sure that it's much of an indicator of anything.
Kotlin is simply a much more modern option than Java in general, and doubly so for the old version of Java used for Android. Giving Kotlin some official backing gives it a lot of credibility. The big argument favour of using Java over Kotlin until now has been that Kotlin was seen as more of a fringe language than the one (Java) officially endorsed by Google. Now that has changed. As a Scala developer I'm quite happy that Kotlin is getting this much attention as I see it as Scala-lite. I doubt there's a campaign of any sort, just lots of excited developers who are sick of Java and excited about Kotlin.
"Go" the language is tricky to search for as just the word "go", so I wouldn't read much into that. Many job ads contain the word go, but have nothing to do with go the language. e.g. "...go to our website..." "...go above and beyond..." etc.
