Are cores (device abstraction level) of OSs written entirely in C? (Like: “UNIX is written in C”)
by soulcougher73 in Programming Languages

Are cores of OSs (device interaction level) really written in C, or "written in C" means that only most part of OS is written in C and interaction with devices is written in asm?

Why I ask that:

If core is written in asm - it can't be cross-platform.
If it is written is C - I can't imagine how it could be written in C.

OK. And what about IO exactly - I can't im

by Triumph in Programming Languages

I have this simple python expression:

fscript.write (("update %s va set %s = %s where %s = %s;") % (argv[1],argv[2],vl[0],argv[3],vl[1]))

And I would expect to receive output like this

How can I add pages written using Tapestry5 to a web application already written in Tapestry4?
by Maxton in Web Design

I'm trying to add pages written with Tapestry5 to a web application written with Tapestry 4 on Apache Tomcat. Assuming I have the necessary jars in $tomcat/shared/lib.

.Net - Can a Class Library (dll) written in .Net be used by an application written in C or C++?
by FlyOnTheWall43 in C & C++ & C#

Let's say I have written a Class Library (dll) in .Net and now I have developers using it in their .Net applications.

However, the library itself could probably be useful also for developers writing natively (in C or C++). So my question is if my managed dll can be used in C or C++?

If not, why? Maybe I must add some specific code to make it available to native coders?

Any PHP IDE written in C?
by cmt95 in PHP

It is my experience that all PHP IDEs written on Java are slow. You just can't compare the performance with Visual Studio. I use Aptana and also used NetBeans. Most of the time, your Intelli-Sense will open when you have moved forward typing syntax.

Is there any PHP IDE that meets the performance of Visual Studio?
