Of the safe languages that I know have been used for operating
systems, there have been C# (Singularity, Windows 8?), Java (JNode),
and Haskell (fillet-o-fish); but there are languages that are perhaps

I'm exploring pypy's code so as to speed up callbacks from C code, so as
to speed up sqlite module's UDF.
I have some questions:
- What are the differences between ctypes, rawffi and ffi. Where
should each one of them be used?
- I see that ctypes is build on top of rawffi and ffi. If one wi

Just musing -- if pypy can discover pure functions (or functions with simple

I worked on the Tunis OS at the University of Toronto, which was an OS
written in Concurrent Euclid. I think -- especially if Software Transactional
Memory works out, there will be interest in writing an OS, not in RPython,
but in Python. So then, well, maybe you will want a JIT ...
I think we

I know; there are experimental OSes in various languages, including
also high-level languages dev

I agree with William's point of view. Yes, I would imagine that C is
a good and well-supported language to do this kind of things. If your
