X11, Window Managers Any modern operating system consists of layers upon layers of systems, services, and libraries. Increasingly, no one can possibly have full understanding of all the layers of the cake. Here's RedHat developer Peter Hutterer's description of what it takes to move the cursor on your screen. Interesting to get back to the basics, and a good reminder of how complicated this stuff really is.

Laurence,

"As much as I don't begrudge the fantastic choice of toolkits we have available, things sure were a lot more fun back then. It felt more an art, these days software development feels more a matter of reconstructing existing blocks of code like Lego bricks."

I know, I wrote a few GUIs myself in dos, and though they weren't powerful by any stretch, they were certainly much more expressive and creative than what you'd find in a standardised toolkit today. When you have full control over the whole stack, you can come up with some interesting ways of doing things. And though nothing is necessarily stopping you from designing creative interfaces today, it's a foregone conclusion to most modern programmers to use components that already exist and not even contemplate how one might do it from scratch.

I had worked on a battletanks like game, the entire interface was "skinned", where each button was actually a bitmap, and in it portions of the screens had a mouse cursor. There was a horizontal photo inventory of things to buy, which was larger than the screen. The mouse position was tracked relative to the inventory, but the inventory was auto-scrolled with momentum to keep the mouse cursor in the middle of the screen. The net effect was that small movements of the mouse would work normally but large swoops would give the inventory momentum in the opposite direction.

I miss those creative programming days. Those were the days everyone was free to implement whatever they could code up without worrying about any exclusive software patent BS. I despise the direction our profession has taken.


"That all said, my sentiment could also be down to the fact that back then I coded for fun, where as these days I code for a living."

I relate strongly to this as well. The projects I've done personally have pushed my abilities much harder than any of the work I've taken professionally. I'm kind of disappointed in the CS carrier at this point. I still love computer science, but the jobs that are available to most us are frankly not worthy of our degrees. I guess those who enjoy CS deeply should stick to academia and avoid business since 90% of what gets done in business isn't CS work at all.

Anyone on Long Island doing real CS work? I'd love to chat ;)
