The Contiki Desktop OS for C64, NES, 8-bit Atari,

Adam Dunkels writes "This is for those of you who think that a text-based operating system that fits compressed on a 1.44Mb floppy counts as 'tiny': the brand new Contiki operating system and desktop environment for the Commodore 64, with ports to a bunch of other platforms such as the 8-bit Nintendo Entertainment System, the VIC-20, 8-bit Ataris, Atari Jaguar, the Tandy CoCo, and the Apple ][ under development. The Contiki system includes the following: a multi-tasking kernel, a windowing system and themeable GUI toolkit, a screen saver, a TCP/IP stack, a personal web server, and a web browser. The Contiki web browser, which is likely to be the world's smallest browser given its extremely small memory footprint, is the world's first true web browser for an 8-bit system and probably makes the 21 years old Commodore 64 the oldest system ever to run a real web browser! All of the above programs are contained in a single, fully self-contained, 42 kilobytes large binary. The entire Contiki system with all programs running simultaneously is comfortable in 64 kilobytes of memory. The name 'Contiki' is derived from Thor Heyerdahl's famous Kon-Tiki raft which was able to sail across the Pacific Ocean despite being built using prehistoric techniques, something previously thought impossible. There are also screenshots and a FAQ avaliable."

Bigger is not necessarily better.

This gets me to thinking about how much programing is probably "junk" programming these days. Anyone remember the sequal to Elite? Elite 2: Final Frontiers I think it was called. That had thousands of systems, planets, bases, stations, etc... set up in a game that had "realistic" physics. You could actually land on the planets yourself!

It was 1 disk big (1.44 floppy).

Now I look at Freelancer. A big CD full of great graphics. Yet at the same time I see it as not nearly as complex and thought out as Elite 2.

This is an interesting attempt not to make bigger programs, but tighter ones. Making the most of what you have. It feels like there is so much available on computers these days, that programs aren't concerned with getting the most out of it, just using as much of the bells and whistles as they can. Imagine using the same mentality on a modern computer!

Re:C64 is the oldest? What?

OOPS! RTFA!

Drat, It looks like the Atari version is "under development". C64 still wins (temporarily)!

Re:Cool, but..

Because it is fun.

Programming on old 8-bit systems is very different from programming for windows/unix. You must know the hardware better and do optimisations you would not even think about on a modern computer.

Some people find that challanging and fun. Not everything needs to be useful.

An amazing project.

Although the focus of this project is not the technology itself I think. This guy has proven to any employeer he will ever approach that he has superior skills when it comes to programming under tight constraints. Enjoy working in the embedded systems industry (and making money hand-over-fist doing it)!

What else is interesting about this is that it goes to show how foolish and blind nearly the entire computer industry is when it comes to technology advances. People can't upgrade to a 10GHz processor fast enough, when all they need to do is check their email. Companies are constantly wasting servers and replacing them with newer models. This is not necessary. Today's software is written so poorly that super high-end hardware is needed to make up for lazy/poor programmers. Look at what these ancient systems can do. That "old" PIII or PII or K6 sitting on your desk is a power house. What's the problem? The software you're running on it is likely to be wasting 75% of the CPU cycles it eats.

It's a shame there aren't more developers or at least software architects out there with this guy's talent. We'd all be saving a hell of a lot of money I think. Then again, hardware prices would increase in proportion to its long-term value. Then again, there's a lot of savings in many ways (largely environmental -- less junk being dumped into the wild at the beginning and end of a computer's life cycle). Of course, I wonder if most of the blame goes to businesses just trying to get software out the door as soon as possible without stopping to think about good design (in all senses).

Jaw drops...

All of the above is included in the self-contained Contiki binary, which is 42 kilobytes large and runs comfortably in 64 kilobytes of memory.

Kernel, GUI, screen saver, TCP/IP stack, web server, telnet client and web browser in 42 KB? Wow... I suppose the TCP/IP stack is based on his uIP code that's around 5 KB large, using 500 bytes of RAM. =) And I like how the GUI is skinnable. =)

Another cool part is of course that I've studied at the same university as him. hehe.. He was rather well-known there as a "decent" programmer. =) You know, those that writes a complex algorithm, compiles it once, and it works.
