I first thought up this concept about four years ago, before the term “cloud computing” was en vogue. Basically I was thinking how great it would be to be able to pool and leverage the CPU resources of the three computers (two laptops and a desktop) I had within my house. In particular I wanted to be able to use the desktop’s faster CPU to complete workloads for my laptop in a relatively ad hoc manner.

Some video applications I had used could render their output on more than one machine using their own clustering software, but why should it be limited to niche programs like that? I already share disk space, printers, or even TV tuners (via Orb or Media Center Extender), why not my CPU? You can push your computing out on the Internet cloud all you want but a lot of people have a micro cloud of resources already within their home, or workgroup.

At the time it seemed like something that might be esoteric enough to be implemented in Linux so I tried to find out how feasible it was in some Linux developer forums. In my mind I thought it could be implemented as a virtual CPU that the scheduler would only send jobs to if the physical CPU was at 100% for more than ten seconds or so. It would also have to be aware of the bandwidth and latencies of the connection between machines. Obviously network accessed CPU resources wouldn’t be incredibly efficient but any additional processing cycles gained would help.

As the number of cores continues to increase (particularly on the desktop) and devices like netbooks with limited resources become popular this could have been a huge boon. Unfortunately nobody took me seriously. After all, my kernel-level C programming is severely lacking. :)

If the documents SDTimes has received are accurate it would seem that Midori is all about cloud computing. Or put more accurately, heavily abstracting away hardware from software to enable remote or local resources to be used for any given task. It isn’t just for the CPU either. Imagine being able to easily pool the disk storage available on the various nodes of your network into one huge fault-tolerant distributed storage volume. All I can say is that on paper this all sounds incredible.

Microsoft is obviously pretty quiet on the purpose of Midori. The PR people have admitted its existence but they it is just an incubation project; only time will tell. Hopefully it will see the light of day before I die or Duke Nukem Forever comes out, which ever comes first.

*Update: Must be a pretty big story if even the BBC is running it.

Remember XYZ OS? It Was Great

I’ve heard statements like this about every new operating system or office suite for many years now. Oddly enough some people are particularly fond of DOS, Windows 3.11, or especially Windows 95. In their mind’s eye the software didn’t have viruses, didn’t crash (well, DOS usually didn’t), wasn’t “bloated”, and ran on a measly 33MHz CPU with 4MB of RAM just fine. Sounds pretty great right? Wrong.

The software also didn’t do very much (relatively speaking). There was little or no multi-tasking (I upgraded to OS/2 from Windows 3.11 solely to download from BBS‘s in the background). Then there was that arcane 640KB memory limit in DOS you had to deal with.

There was also no Internet (at least what we consider the Internet today); so no WWW, email, blogs, instant messaging, VoIP, or online gaming. Computers also couldn’t do all of the multimedia (music, video, photo editing, record TV, etc) we take for granted today. Here is the real kicker though, they also cost more in nominal and real terms. I remember my first hard drive cost $300-400 and it was only 20MB! I just bought a 750GB drive for ~$100 or so.

Trust Me, It Wasn’t As Good As You Remember It

Here is how I know it wasn’t better back then, if it was, we would all be downgrading back to a 286 running Windows 3.11. A lot of the problems people have with computers today have more to do with the Internet than their OS. If you really want to be as safe from viruses/malware as you were then, don’t connect your computer to the Internet, ever. That will take care of about 99.9999% of your computers problems…and about 90% of its functionality too.

I do have my favorite programs/OSes from back in the day, but they were really only great relative to their contemporaries. That is why I run Vista instead of BeOS or OS/2 (arguably my two favorite OSes of all time). Sure BeOS could boot in 5 seconds on a Pentium 200MHz, but once it was up what would I do with it?
