Taken from OSNews - AMD joins MeeGo - http://www.osnews.com/story/24034/AMD_Joins_MeeGo_Linux_Open_Source_Project


I hope Nokia wakes up and dismisses Symbian ASAP. And the EU parliament 
is so stupid, that they want to sponsor Nokia a bit, just to have 
some EU competitor to other mobile OSes.

The tracking works even you don't have FB account. They just don't 
know your name. But they have your IP and some info from cookies. 
For example :

The FB's cookie life is 2 years.
Of course you can delete your cookies, but how many ordinary people 
do that?

The new Mathematica 8 allows for natural language input - pretty 
nice. Also, you can now export anything you've developed there as 
a C library, or an executable.

Stephen Wolfram's following blog post on using natural language for 
programming is a good read too.

How to use the Kinect sensor bar from the XBox 360 in a different 
way.
Looks to me that they solved a big problem in robotic vision.

so now we just need to add wheels to xboxes and fire thousands of 
them on Mars:)

Correction: The problem was solved years ago with socalled Time of 
Flight cameras. The kinect is just a much cheaper way to do the same 
thing, so now, everyone can do it.

This will make security cameras about 99% better, removing false 
positives, and in fact IDing who someone is.

These reviewers totally missed the point.  This product shows that 
a $100 olpc is close to being feasible.
Kaj

That's what they said half a decade ago. Then why isn't the OLPC 
close to $100?

for their PlayBook tablet purpose -  QNX UI is not modern enough

this is pretty crazy: The latest version of the Linux kernel currently 
consists of approximately 13 million lines of code

13 million lines of code


Linux is on the wrong track! The same can be said about OpenOffice. 
I downloaded it the other day for my new Mac, and I just checked, 
it takes up 427 MB of my disc. It simply takes too much time to deal 
with such software, it being maintenance or just figuring out as 
a user how it works.

That's just the kernel, that's nothing. Try building an operating 
system around it...

Minix 3 is 6000 lines of code.
Andreas
3-Dec-2010
[5367x2]
Not really :)
[Minix 3] is extremely small, with the part that runs in kernel mode 
under 6000 lines of executable code.
Henrik
3-Dec-2010
[5369]
well, I assume that is because much more of it exists in user space.
Andreas
3-Dec-2010
[5370x2]
No doubts that Minux 3 is very small indeed.
Minix* :)

Minix is a micro-kernel. Most of Minix runs in user space.
Still, I'd be shocked if Minix had nearly as many lines of code as 
the equivalent in Linux. Most of Linux's code is device drivers, 
and Minix doesn't have good driver support (though its drivers also 
run in user space, so they're not counted in those 6000 lines).
Andreas
3-Dec-2010
[5374]
And Minix only supports a single platform, at the moment.
BrianH
3-Dec-2010
[5375]
It supports a whole platform? Cool. I thought it only supported part 
of a single platform.
Andreas

Linux's arch/ has 23 subdirectories.
Kaj
3-Dec-2010
[5377x2]
Minix also doesn't have anything beyond the kernel and drivers. As 
with Linux, you have to put a userland, X11, toolkits and a desktop 
environment on top of it
Only then are you ready to add the half a gigabyte of OpenOffice 
:-)
Andreas
3-Dec-2010
[5379]
Heh :)
Kaj
3-Dec-2010
[5380]
But you'll be able to gloat about running your gigabyte on top of 
only 6000 lines ;-)
BrianH

Linux and Minix tend to run the same amount of code, when you include 
drivers. Minix just runs a lot of that code in user space instead 
of kernel space.
Linux doesn't run all 13mil lines of code on one installation. When 
you just include the drivers that it is actually using then the code 
count gets a lot smaller.

I think, it's true that "less is more".
Henrik
4-Dec-2010
[5384]
Less is more, because less code is more managable. On the upside, 
Git may never have seen the light of day, if Linux was a nice and 
small kernel.

Rebol Tutorial guy posted interesting link to programming languages 
future panel. He mentioned Crockford (JSON) mentioned REBOL there. 
What is really nice is the second guy from right, author of pleny 
JAVA libraries, describes that the main problem is rishing complexity. 
He says, that if you add functionality, it will only add-up, but 
never shrink. And also - that in future there might be a winner, 
who does it all, not like nowadays, where for web apps you need 3-4 
technologies. I think his description fits REBOL ...
