- The complete ISO is 4.4 MB in size (when zipped it's 2.8 MB, so you can basically send it around as email attachment, if you really want to).
- It's completely written in assembler.
- It has a nicely working graphical user interface (see the screenshots here).
- You can install it in VirtualBox (other VM solutions may work as well, but VirtualBox is the one I tried).
- It boots from boot-loader into the GUI in around two (2!) seconds! And that's on the VM, not even the bare metal on my laptop.
- It feels fast and zippy, even in the VM environment.
- It comes with a bunch of games, a web server, ftp server, development tools, graphic demos, a drawing program, a CD player, utilities, etc. Remember, that's all from that 4.4 MB ISO.
- Extremely small footprint: After being fully booted with GUI and all, just 10 MBytes of memory are used, most of it probably the video buffer for the graphical desktop.
Higher-level languages and frameworks build upon frameworks build in higher level languages may be nice and convenient. But fast and efficient they are not. Systems like 'Kolibri' remind us of the potential that should be available to us with the incredibly powerful hardware we have at our disposal these days. Yet, our modern OSs tend to fall woefully short of this. Slow boot times, sluggish performance in day to day use, resource hungry to an extend that 10 years ago would't have been comprehensible.
No doubt, time-to-market tends to be the overriding factor these days. Adding new system processes and tasks is quicker if you can do it in Python (or some other high-level language), rather than assembler. But it drives tears in my eyes when I think about all those wasted CPU cycles...

You should Truly check out menuetOS. ASM, 64-Bit, with GUI, boots from a floppy.

wow, I'm quite impressed and it's the first OS I have seen in a long time that shows to be a true own entity that had it's own design feel and not trying to look just like Windows (reactOS) or be similar to (most shells for linux) and it runs on assembler! I need to shove this on to something absurdly slow and see how well it functions.
Speaking of glaoted OS's I have been (using) and all the time slowing ripping away at our closed source "greatest market share" friend and have cut an impressive amount of fat from it while it stills. Now to reshell it and remove all the HTML components and blog it.

You do realize that it is relatively small sine it hardly has any drivers or apps, not to mention ASM code is machine dependant.
This is a pointless post.

"It feels fast and zippy, even in the VM environment."
Sounds like you have some bad experiences with VM performance. Most of the time i forget my systems are running in a VM because the performance is near-native. I'm using VMware and VirtualBox all the time without any problems.

I know even more astonishing ultra light^2 OS - However to run it on PC you need an emulator and thus there is no benefit.
Contiki, a lightweight OS for 8-bit computers. Some highlight of C-64 version:
* Runs from single c-64 floppy.
* Multitasking kernel.
* GUI that provides windowing.
* Needs only few kilobytes of code and a few hundred bytes of RAM. A full system, complete with a graphical user interface, needs about 30 kilobytes of RAM so 64K of C64 is plenty.
* TCP/IP stack and internet connectivity (needs additional hardware for C-64 obviously.
* Can run and comes with web server & VNC server (as example one webserver run with contiki can be found at http://www.c64web.com/ ).
* Also web browser & telnet client available.
Of course this is for most users only a curiosity but it is an interesting one at that. I had hard time believing that this kind of system could really be made at all.
For more info, listing of systems contiki has been ported to, screenshots, etc. see:
http://www.sics.se/contiki/ (official homepage)
As for Kolibri, this interest me somewhat as it could make my old 386 (maybe even my 286?) usable for more than just a dumb terminal connected to my Linux server with null modem cable :)

@Foobar: If your idea of progress is going back to the stone age then thats fine. What part of the fact that ASM code is machine dependant did you not get? You can limit the Linux kernel to 2.2Mb to run on Kilobytes of RAM too, thats what embedded systems do anyway. Why is this persons work so phenomenal?

Ever heard of Contiki? Not for x86 arcitechture though, it's an amazing OS for 8-bit systems. For example the C-64 version provides a multi-tasking, graphical OS with windowing GUI capable to run (these are all provided on single floppy) networking, browser, telnet client, screensaver, HTTP & VNC *servers*... and more. I am simply astonished how they have ever managed to pull this out with (in case of C-64) 1mhz processor and 64K RAM (with only couple kilobyte footprint by OS itself).

wow this is great, EXCEPT...
where is the web broweser???

Iam a newbee to this but at last I found a thinking person on the net.In the seventies and the eighties they made the assembler programmers unemployed or they had to become c-programmers.It is not just a question of speed but also of of safer and more efficient computing.We had in my country ABC PC:s but unfortunately they went bunkrupt.They wrote their OS in assembler.All those C-languages is a waste of time.They allways create bugs take a long time to develop,all those snobs thinking they are clever can sit with their bugs, and maintain their bad systems.Besides not knowing assembler they know nothing about LISP and other useful. programming languages.There is no point in this because they will never understand what is a good OS so let them stick to the shit they use.People knowing assembler are seldom rich,they often prefer to work at home,they program for fun and seldom for money.I hope UNIX will crush in 2038 so they will understand.It is the same shit W7,BSD,OS X,Linux,etc.
