Math
I need to brush up a bit on my math and would like to know how functions of this kind are called. I know linear, polynomial/rational and trigonometric functions and their general forms. Can anyone point me in the right directions how these kind of functions are called. Continous with a slope > 0 for all x and limiting asymptotes for the min and max y value.

Is there a way that I can obtain a list of my routes from a controller in Play 2.1.1 / scala? I'd like to create a dynamic index page which lists possible URLs to access some services. This is not the end solution, but would be nice nevertheless.

CubifyX

A friend of mine who runs a professional prototyping company is looking to enhance his techpark with a cheap 3D printer (expensive ones already exist) in order to print multicoloured promotional give aways. He asked me about my opinion of the CubifyX.

http://cubify.com/cubex/index.aspx?tb_cubex_learn

I do not know any first hand reports, so I thought I would ask here. 
Requirements:
- multicolour support
- ease of printing, no tech fiddling etc.
- support for "arbitrary" models (e.g. I do not understand if you are locked into some special software stack with cubify to design your models)
- machine is pre-build and ready to go (no tinkering required)

I would be interested in any first hand reports, links etc. I personally guess that my friend won't be happy with the machine, but I would like to have a more informed source of information.
Thanks!

Just as an information: I currently working on a port of grbl to work with the Trinamic TMC26x stepper drivers as provided by these shields: http://www.motioncontrol-community.org/?page_id=36#tos100

In principle these are very powerful stepper driver chips, the only problem is that the Arduinos which the shield is designed for, is probably a bit underpowered. However - that is too early to say - if anyone is not afraid to live on the edge, my branch of the grbl firmware can be found here:

Please note that you need to switch to the "trinamic" branch.

Getting a bit bored with tulips and these other flowers. Guess I need to go to the wholesale market soon.
