i read that you can package version-specific code in the same JAR. maybe keep the Rx JAR the same with a special java11 folder?

@carlw I'll look into that. I already have some PR's and issues coming in with Sun dependencies needing to be removed too.

java 7 (javafx 2.2) -> 8 was a pain because I had to juggle two JARs. i think 11 will let you keep the 8 jar the way it is and pack in 11-specific classes, say under /java11

thanks! @hudsonb I've done this in other languages before but I haven't tried this with javafx

but check it out, it works!

The code was adjusted according to your notes but here's what I ended up with -

-.kt

you were totally right, it was better to pass in the writable image. I was basically doing nothing with the pixels before

If anyone has the time, could I get feedback on a thing I'm making? https://github.com/spearskw/kafka-gui/tree/master/src/main/kotlin/ui In particular, I think I'm mis-using the

find

function and should probably use scopes for the

routeActions

variable (or maybe something else?). I also don't know where to put startup config, so I'm putting it in the

MainView

constructor. I'm sure there are other things I'm missing that could be improved as well

@amanda.hinchman-dominguez glad you got it working. You can also ditch the

WritableImage

and

makePixelsBrighter

method and simply apply a

ColorAdjust

effect to the

ImageView

... something like this:

imageview(img).apply { effect = ColorAdjust().apply { saturation = 0.5 } }

thanks @hudsonb! I'm actually doing this for more than just making an image brighter - I'm kind of working on image processing and the hardest part is always the easiest. Figured out how to start turning the image around and intending on mirroring it

this might be a really fun blurb to write up when I'm done messing around

@Kevin I'm super interested in looking at your code in the next day or 2 - I only skimmed for a second (because I don't have time today) - I've always wanted an excuse to look at Kafka, and there are some functions I don't necessarily recognize with routing and all that - can you tell me more about what the project is about?

Thank you! We use Kafka at my job for everything, even the front end. Instead of using HTTP and REST or something like that, we’re using Kafka and MQTT, which means I can’t look at the network tab to see the traffic between the front end and backend. So I wanted to make something that would let me look at messages going through Kafka in an easy way, basically as a replacement for my network tab in Chrome. The routing stuff in there is a bit weird. Instead of talking to Kafka directly, I’m using this library called Camel that allows for connecting a bunch of different things rather easily. I can consume messages from Kafka by saying

from("kafka:<params>")

and I can route / transform those messages as I need to, and send them off. In this case, I’m sending them to in-memory queues by saying

to("seda:<queueName>")

, and then consuming from those queues elsewhere. Honestly, might be a bit of overkill if I really am just focusing on Kafka

hmmmm - agreed. Still, do what works - this will help with a lot of questions I had about the code.

On an irrelevant note, how do you deal with passing a function as a parameter but the call using the variable requires

Color!

rather than

Color

?

will a nullable check work here?

and default to color white

It's not like you can Cast the function return type as non-null

oh DEFAULTING

I always forget

Wait, can you do with with a parameter?

wdym as a parameter

can you show me?

such as

foo

or

bar

where do u call that function
