Gameboy hello world
Very cool. Something I really love about assembly programming is that there's no black magic between me and the hardware. I can know exactly what every bit of every instruction means by looking at the instruction set documentation, and I can look at the computer architecture documentation to know exactly how to access each device.<p>Also, the "API"'s you have to learn are incredibly simple compared to learning API's for every framework and protocol in high-level programming. If devices are memory-mapped, than all I'll ever need to know is load and store. I just need to look at the registers that are available for each I/O device, what their addresses are, and what the bits represent in them. From there I access them all the same way: load and store. Couldn't possibly get any easier than just moving things around between registers and memory.<p>Compare that to high level development like web development, where you need an understanding of HTTP on top of one of infinite different web backends, written in different languages, all using different libraries with different naming conventions and different programming paradigms, plus knowledge of HTML, CSS, possibly another smorgasbord of frameworks, plus knowledge of decent security practices, databases, operations, and the list goes on.<p>It's obviously apples to oranges though, and I can produce a lot more real-world value doing web development than I can doing assembly programming, at least just as one person. My point is that I really like the simplicity and straightforwardness of writing assembly, at least in the few very short times I've done it. Maybe large assembly projects have all the same challenges as high-level development or worse.
