Using Multiple Languages

I'm not familiar with OpenCV as it pertains to Java. I'm sure someone else can point you in the right direction.

Thanks. I was looking at a comparison between just sticking with one language, sticking with one language, but making some exceptions, and allowing every language, even if it is as old as Forth!

I know that almost every software giant, like Google, Microsoft and Facebook (IDK about Apple, so I won't comment), use multiple languages to do their processes. Google has most of it's code written in Java, but uses quite a bit of python interleaved.

Our team has, for this year, stuck to using just Java, because our mentor's told us that it is the "best" language. While it isn't a bad language (I like Java, actually), There are some places where I think it is impractical to use Java. In this case, I am thinking solely about OpenCV. It is probably one of the most feature-packed CV library, but installing the Java connector seems like rocket science. Not only that, but SoCs typically have crappy JVMs, making it a hassle to run the code. OpenCV, for example, is written in C. That means that the Java interpreter needs to run the binaries continuously. In the case where you have limited resources like RAM, that seems quite impractical, the same reason why a Raspberry Pi + Minecraft Server don't always work out well, if you are a typical gamer!

Typically, linking multiple languages isn't the easiest thing to do. However, in this case, the cRIO is the i2C host server and the Pi is the i2C slave, obeying the instructions of the cRIO!

On a full-blown Debian system, I noticed that the JVM takes quite a bit of time to launch. It takes 1-5 minutes for Minecraft, Vanilla, to load on my MacBook. I think the reason why I get such load speeds is because the DSP of my Pi isn't powerful enough to max out my Hard Disk, another reason why I shouldn't waste my money buying an SSD for the Pi! That's why when you go on my site, when the chrome bar is moving backwards slowly, the HDD is being read, and the site is being generated/downloaded as the circle turns around!

This is just what I have noticed when programming.
