Pekr linux is fast on boot time i mean a genuine  linux ubuntu 10.10 
on a 1.6 ghz procesor like my netbook boots up in 30 seconds wich 
isn't bad at all compare to the 5 minutes of boot time needed to 
 start windows 7 starter ed on same machine...

That's how computers should work in general. My new 2.53 GHz MacBook 
Pro with solid state drive boots in 17 seconds or so. My old iBook 
G4 boots in 50 seconds. Still my old 50 Mhz 68030 Amiga could boot 
in less than 10 seconds.

then you have chromeOS which boots in 8 secs on my machine or android 
they are linux ... but very specialised one they are closer in that 
aspect to  what does switchboot
it's a know thing that when your kernel has to scan and locate proper 
drivers to fit your hardware in a driver library and load them as 
module that's the slowest way...
so the basic optimisation people were doing at the begining of linux 
was to adapt the kernel to integrate the specific driver needed for 
your hardware and only them... But this is flexible and doesn't fit 
with the hot plug need introduced by USB port and periphericals.
so now we have for example ubuntu 10.10 in netbook version which 
is basically a kernel with a driver module library that only fits 
the hardware you can find in the netbooks...  as the hardware library 
is smaller then it boots faster
I use nosplash quiet and fast-boot options for my kernels ... doing 
this I gain 10  seconds in boot sequence.
after you can gain another 10 seconds of boot time just by  using 
X11R6 + openbox windows manager instead of gnome + Metacity or kde 
etc...
maybe using wayland instead of x11R6 + compiz or metacity can speed 
up your boot sequence too
the  closer you linux will be to your specific hardware the faster 
it will boot ...
but 1 second is still amazing .. I would say I this swichboot demo 
was about accessing to a regulare openbox window manager instead 
of a dashboard I would be already buying it :)

Geomol, did yours come with a standard Apple SSD or your own? I'm 
interested in replacing the drive I have in my Macbook.

from cold boot, I remember being able to print a sheet on my amiga 
@28HMz before my friend's PC was able to finish booting Win95 on 
his pentium. :-)

That's what happens when you boot from ROM and implement a good chunk 
of the functionality in hardware rather than software :)

We need to get this guy to sit down with the programmers of the Quad, 
and teach them how to make use of all aspects of flight.

I've had fun sending commands to printers a few years ago, its a 
lot of fun   :-)
Henrik

[5656]
I did it too. I didn't find it particularly amusing, since different 
printers understand them differently. :-(

depends why you're playing with that... I was just hacking my printer 
for fun... trying to build a print manager... that's another story 
 ;-)
Henrik

I managed to build one, which is simple. Sending commands to the 
printer, I had to give up and chose to build postscript files for 
an adobe postscript driver instead and let it handle the rest.

Interesting. Java has the same flaw that PHP had with a specific 
number.

Nokia experiments with the Bubble interface - IIRC, it is QML based 
(Qt's VID inspired declarative aproach, second one, after JavaFX)

Just not sure I want to chase bubble around to get some action done

a good design characterizing itself by immediate function transparency.
this is....well...what is it?

one quick improvement would be to make the bubbles not move.

LOL!

(that is all I can say about the bubbles)


oh wait..........now the "LOL" has floated down here in the message.......whoa..............it

Snapdragon is Qualcom's ARM based CPU/chipset. OMAP is Texas Instruments. 
Samsung has its own, nVidia has Tegra, Broadcom is another big one 
I know. Full list of licensees can be seen here:

If the HP's WebOs takes off .. maybe we don't need to port to Android 
:)
Isn't WebOS a Linux variant?

Yes, "a proprietary mobile operating system running on the Linux 
kernel, initially developed by Palm and purchased by Hewlett Packard 
(HP) in 2010."

I'm convinced that HP will succeed to fail with WebOS. Wrong CEO 
and a lot of HP products are mostly crap.
BrianH

HP has been succeeding with crappy products for years, so they might 
succeed with this. Too big to fail completely.

HP's slate runs flash .. you need flash to view porn.  Ergo, this 
slate will sell.
Furthermore, HP has been giving away slates free with their printers 
.. as printer control devices.
They can continue to do that for their servers

Well, at least they just straight up copy the iPad now. I'm sure 
they only announce now, because the iPad is about to be updated.
