General Development "In this tiny ebook I'm going to show you how to get started writing 6502 assembly language. [...] I think it's valuable to have an understanding of assembly language. Assembly language is the lowest level of abstraction in computers - the point at which the code is still readable. Assembly language translates directly to the bytes that are executed by your computer's processor. If you understand how it works, you've basically become a computer magician." More of this, please.

"6502 was fun in its day. So was 68000. But as someone else already pointed out, compilers are damn good these days.

... but can be out-performed on many machines by a decent assembler programmer.

As CPUs became more orthogonal, I bet the advantage eroded pretty quickly. Compilers can just keep track of more information to make better decisions on optimizations, such as efficient register scheduling.

And it's poor software engineering to dive straight into assembly without finding the bottlenecks first. Even small micro-controllers like PIC are better programmed in C first with a directed migration to assembly based on performance requirements.

Except for the smallest of embedded systems, C is perfectly viable using something like Contiki ( ).
