I’ve tried to find out lately what is the job queue of a supercomputer. I wanted to know what kind of software runs (I’m not talking about the actual OS), the process of running the software on a supercomputer. It seems is very difficult to find information on the Internet about it.

“ From your 202 subscriptions, over the last 30 days you read 3,055 items, starred 28 items, shared 30 items, and emailed 0 items “ . This is what Google Reader trends say about me. What this means to me is that from what I read I consider valuable and worthy to be shared less than 1% of all the posts.
From the 202 subscriptions most of the noise comes from Digg, Reddit, Delicious, Scobleizer’s Twitter Favorites, my own alltop page feed and my own readtwit feed.
| Subscription | Posts per day | Percentage read |
| Digg | 134.5 | 3% |
| 72.6 | 4% | |
| Delicious | 46.8 | 5% |
| Scobleizer’s | 68.7 | 8% |
| My alltop | 149.7 | 3% |
| My readtwit | 22.4 | 5% |
What annoys me most are the low percentages that I get from Readtwit and Alltop. I would have thought that if I choose my domains of interest (websites on alltop) and people I follow ( on twitter ) carefully I woud get a noise to signal ratio a lot bigger. It doesn’t seem to be the case.
From all the websites (services) that are trying to improve the situation (noise to signal ratio) it seems to me that only Postrank and Feedly are having a little bit of success (I do use these 2 services on a daily basis). The others such as Lazyfeed, Daily Perfect are still far behind.
I see a possible solution to this mess and I will try to describe it below.
I am pretty sure that Postrank filtration algorithm can be tweaked on a per person basis, but I am almost sure Postrank doesn’t have the resources right now to support this.
I am sure that the aggregation (clustering) technology that Google is using on the News site can be used on the Google Reader but I am also sure that Google has no interest in doing that since their scope is to have their ads displayed on as many pages as possible.
I imagine that Feedly which takes into account at the moment what I shared on Reader and what I twit in the last 30 days to decide what it’s more important to me could base their recommendations also on what my friends on Google Reader network and on Twitter promote.
Now if somehow someone could integrate all these 3 technologies together I know I would pay that company a small amount each week in exchange for a much better signal to noise ratio.
This is what real programmers can do in 4096 bytes. Keep in mind that most probably the homepage of Skunkworks now is around 70-80Kilobytes

I saw a lot of very impressive stuff done in 4K or 64K in the last 10 years but this is without a doubt the most spectacular one.
BTW do yourself a favor and go to Youtube to see the HD version of this clip.

I’ve got the news about the new Google endeavor from their official blog yesterday morning. After reading all sort of comments on the net I’ve realized that I don’t see any need for Google Chrome OS and most probably is just a preemptive strike against Microsoft at one level and probably Facebook at a different level.
Let me explain. Most probable Google Chrome OS will consist in a Linux kernel, a new window manager and Google Chrome browser on top of all these. Keep in mind that Ubuntu as of 9.04 has an official release for ARM processors. If you need a similar experience today you can get Ubuntu Mini iso (which is a 12 MB download) for x86 architectures. Most probably starting with 9.10 release it will be available for ARM architectures also.
Then, check the instructions from this ubuntu forum . Idea is that you need to install a few packages from the command line:
sudo apt-get -y install gnome-core gdm network-manager-gnome fast-user-switch-applet human-theme x11-xserver-utils tangerine-icon-theme gnome-themes-ubuntu ubuntu-artwork jockey-gtk gnome-screensaver gnome-utils
apt-get install laptop-mode-tools ubuntu-laptop-mode wpasupplicant # this one is for supporting a laptop
apt-get install maximus # this one is for achieving the maximizing effect from the Ubuntu Netbook Release .
Then using Ubuntu Tweak and Add / Remove Programs from Ubuntu desktop environment you can install Firefox 3.5, Google Desktop (with gadgets support), Google Gears, AWN and Firefox Prism . I’ve also installed Pidgin and VLC. The bottom line you get an web oriented OS which takes around 80 MB of RAM (at idle) and is very responsive.
On the other hand take a look at all these links:
http://news.cnet.com/8301-13860_3-10282037-56.html?part=rss&tag=feed&subj=Webware
http://news.cnet.com/8301-13860_3-10280270-56.html
http://news.cnet.com/8301-13860_3-10006582-56.html
http://friendfeed.com/scobleizer/3a1eac42/why-did-google-announce-chrome-os-this-week-well
And all these announcements from Google related to Google Apps out of beta this week and Google Chrome OS makes more sense.
So the way I see things Google won’t be able to change the status quo in the OS world.
But if Google some how succeeds we will run a Google OS on a Google approved device using only (is going to be only a matter of time ) Google services (no Facebook or Twitter for you). And btw you will probably have Google Analytics at desktop level 
.
For all these reasons I will stick with the Web OS option that I described at the beginning. If I am wrong in my assumptions let me know in a comment.

If this is going to be at least half as good as the advert, I know what’s going to be near my Wii in the very near future .

Another way the technology will help you in the very near future. Don’t mind the fact that the software is slow or the fact that the screen takes 2 seconds to do a refresh. The important part is the hardware behind this gadget. I am sure that in less than 2 years time we will have an ebook reader which will have colors, very good refresh time (maybe even video capable) and if we are lucky will be subsidized by the content providers (the same thing that the communication companies are doing now with the phones).

Take a look at the video below
and then read the review from Techcrunch. I am inclined to say that the company behind this piece of software is going to be big in the very near future
