Linux Linus Torvalds included patches into the mainline tree which implement a stable userspace driver API into the Linux kernel. The stable driver API was already announced a year ago by Greg Kroah-Hartman. Now the last patches were uploaded and the API was included in Linus' tree. The idea of the API is to make life easier for driver developers: "This interface allows the ability to write the majority of a driver in userspace with only a very small shell of a driver in the kernel itself. It uses a char device and sysfs to interact with a userspace process to process interrupts and control memory accesses."

Umm...that mentality has big problems....nothing gets produced or an over engineered POS is designed.

There's always compromises to be made.

And there's a lot to be said about getting something out there that people can chew on and give you feedback on instead of just sitting around a table talking.

Oh, come on. The above is the equivalent of invading Iraq and failing to do the research before hand - now look what has happened.

Same thing if you don't investigate, document and design - you end up with a giant cluster f--k that becomes so hacked, so badly managed you're forced to chuck out the whole thing and replace it - thus costing money, thus very inefficient.

If things are properly documented, properly designed, they can be maintained for the long term rather than the short term gratification of the programmer in question.

If Linux developers and users want to get it as a viable desktop operating system, the above approach is completely ridiculous; simply throwing things out every couple of months or years because someone didn't do their homework.

Write a program, and do it right the first time.
