I have an mbed which has a small ARM Cortex M3 on it. Basically, my effective resources for the project are ~25Kb of RAM and ~400Kb of Flash. For I/O I'll have a PS/2 keyboard, a VGA framebuffer(with character output), and an SD card for saving/loading programs(up to a couple of Mb maybe)

The reason I ask this here is because I'm trying to figure out what programming language to implement on the thing. I'm looking for an interpreted language that's easy for me to implement, and won't break the bank on my resources. I also intend for this to be at least possible to write on th device itself, though the editor can be interpreted(yay bootstrapping)

Anyway, I've looked at a few simple languages. Some nice candidates:

Forth
BASIC
Scheme?

Has anyone done something like this or know of any languages that can fit this bill or have comments about my three candidates so far?

Hi folks, I am going to develop a facebook game as topic for my thesis. I am wondering which programming languages i should choice. I am used to programming in .NET.

Are there any objective measures for measuring the power of programming languages? Turing-completeness is one, but it is not particularly discriminating.

What do you consider to be a high-level language and for what reason?

as seen on Programmers - Search for 'Programmers'
Traditionally, C was called a high-level language, but these days it is often referred to as a low-level language (it is high-level compared to Assembly, but it is very low-level compared to, for instance, Python, these days). Generally, everyone calls languages of the sort of Python and Java high-level… >>> More

Learning about the low level

I'm interested in learning more about the PC from a lower (machine) level. I graduated from a school which taught us concepts using the Java language which abstracted out that level almost completely. As a result I only learned a bit from the one required assembly language course. In order to cram… >>> More

In informatics theory I hear and read about high-level and low-level languages all time.
