[Tech News] Interesting technology

Kind of underwhelming.
The spelling corrector spelly looks interesting.

I already pointed to in in Links group. Looks interesting. I thing 
that we might have here some chance with R3. Maybe, as a "killer 
app", we could think of alternative client frond-end for services, 
which have public APIs. That way such clients might be downloaded 
by millions, making REBOL a bit more popular :-)

Project Natal for XBox 360 looks very interesting:

How it's used.

I like this one - http://www.camspace.com/- allows you to take any

A new type of harddisk designed to compete with SSD. Very interesting:

Is it a magneto-optical drive ... like we had years ago?
Henrik

[4089]
No, it basically a harddrive with a rectangular magnetic plate, and 
instead of one head it has millions sitting in an array in another 
plate above the magnetic plate, placed on a very thin lubricant. 
the thing is that the heads can move up to 250 micrometers back and 
forth above the plate using a piezo actuator. Everything is tightly 
packed together with no loose parts.


There isn't much motion and the frequency of the motion is only about 
800 - 1000 Hz. However the head arrangement allows for massive parallelization 
of read and write ops. Currently only 64 heads can be accessed simultaneously, 
but I suspect this number will go way up. If the drive is idle, no 
power is used as nothing is moving. Due to the low frequency of motion, 
there can be a latency of about 0.5 ms, but the read/write speeds 
far exceed that of SSD. I suspect this frequency is used to avoid 
thermal and power problems.


The difference here from SSD is no need for specialized file systems, 
current manufacturing methods can be used and it uses even less power 
than SSD. It can also freely be scaled and adapted to 1.8", 2.5" 
and 3.5" drives, from what I can see. The durability for writeops 
on the same sector would be same or better than a harddrive.

I can see it reducing latency [head movement time] but rotational 
delay is likely to be the same. You could optimise for that, but 
that would need tweaks to the file system.

Maybe they got the inspiration from 1950's drum storage -- one head 
per track :-)

Nothing is rotating.

Sorry -- my mistake.

There's some interesting discussion of the device in the comments 
here:

DataSlide...finally!
Of note, about 20 years ago I wrote up a paper to build a camera 
with a 100x100 CCD that could capture huge images by vibrating the 
aperture (which would be small than a standard pin hole).  The speed 
of your CPU would control the time it took, thus faster computers 
= higher ISO values, that simple.


You would also be able to point it at something far away, and tell 
it to focus on that region, thus getting a clear image even at a 
very far distance.


This is still worth building today.  A $10 camera that takes 10Kx10K 
image in about 1 second, not bad.  Through software you could remove 
things that moved as well, for example cars that park over night, 
people walking around, etc.  Over several days you would end up with 
a crystal clear image of anything that was not moving.

Opera Unite: a Web server on the Web browser


With Opera 10, we are introducing a new technology called Opera Unite, 
radically extending what you are able to do online. Opera Unite harnesses 
the power of today's fast connections and hardware, allowing all 
of us to help define the future landscape of the Web, one computer 
at a time. Read about how Opera Unite is going to change the way 
we interact on the Web on labs.opera.com.

nVidia prefers WindowsCE for ARM based netbooks over Android. Finally 
someone confirmed what I think too:

Opera unite: Has anyone given it a try? This might become some really 
interesting thing.

Etoilé now has a VirtualBox image, for those who want to play around 
with it quickly.

Is etoile an operating system?
Kaj

A desktop environment on Linux
Henrik

The first one based wholly on GNUStep, AFAIK.

There have been other attempts, but they didn't get very far
Graham

I downloaded it ... and it was zipped :)  Is it worthwhile installing??
Henrik
22-Jun-2009
[4113]
I think it's very early in development, so it's only if you are curious 
what it's about.
Graham
22-Jun-2009
[4114x2]
Drat!
So, I need to learn objective C to take advantage of this ...
Henrik
22-Jun-2009
[4116]
That's one of the big points of Etoile. And GNUstep in general.
Graham
22-Jun-2009
[4117]
Is there a way to leverage REBOL here?
Henrik
22-Jun-2009
[4118x2]
Nope.
(but I've often considered building an Etoile or Squeak-like desktop 
in REBOL)
Graham
22-Jun-2009
[4120]
So, no way for rebol to use the Gnustep libraries to create a GUI 
?
Pekr

What is GNU step, in one sentence, without pointing me to Google? 
:-)
Henrik
22-Jun-2009
[4122]
GNUstep is an open source implementation of the OPENSTEP specification.
Pekr

I would better look into upcoming versions of BSD, which are going 
to be GPL free :-)
Graham
22-Jun-2009
[4124]
Huh?  BSD is BSD licensed surely?
Henrik
22-Jun-2009
[4125x2]
Graham, well, you could probably build the GUI files using REBOL, 
but that loses another point of GNUstep. It has a pretty powerful 
GUI builder that leverages late bindings in Objective C to build 
most of the functionality of the GUI without writing code.
but I think there are Smalltallk bindings available.
Pekr

Graham - BSD is not fully BSD ... it is compiled on GCC, which is 
GPL, no? I have heard they are reaching the state of purity now, 
so no GPL poison anymore ...
Graham
22-Jun-2009
[4128]
I didn't think that program compiled by GCC affected their licensing 
.. unless they're including GCC in their distros
