Dunno why it is being considered a breaking news, but OSNews.com 
seems to be happy about Broadcom open-sourcing their drivers :-)

Those quadrocopters are getting crazier by the week.

two highlights of that "dog" are when it recuperates (in real time) 
when pushed sideways... the other is at the end... when it starts 
running and JUMPS over a 3 ft wide obstacle... look at how precisely 
its hind-legs land just beyond the obstacle... waiting for the proper 
balance to occur...

now THAT is downright scary

Maxim, that's the old video - there's a new, improved robot now
wow Henrik - that one is so advanced!

IT is getting there.  With the copters, it means one day truly having 
"flying cars" because the control systems should be good enough they 
evoid "everything" but let you pick a place to "go".

funny, I am currently in brazil and there is a gyrocopter producer 
here near sao paulo which I will visit next week.
will try a ride... :-))
btw, does somebody has a advice for getting a helicopter license 
in the USA? 

found many in the net but would appreciate a local advice for the 
best location.

You "really" want to learn to fly a helictoper? It takes a lot of 
study, is time consuming, very hard to get time on a machine, expensive, 
and, THEN what?
Just asking...
Steeve

like Rebol, somewhat...
Just joking...

of course I really want to get the license. why not?
investing in personal abilities is always a good choice.
but in general you are right, making this license 
without the intention of some commercial usage could be 
seen as wasting time... execpting for me, at least I can 
add this to my fixed wing I made many years ago and what comes
after the THEN? well, the last time I flew is many years 
ago but hey man...it was a original refurbished tiger moth
at one of the coolest location ever.
as you can see I can use it also to brag a little bit ;-)

but ok, this is a little off topic for this channel...

I wonder if this is good for learning TCP/IP.

Is this like Simon's Basic?
Henrik

[5181]
it seems to be an extension for plain BASIC.
Geomol

Yeah, TCP extension commands to BASIC:

Quite cute, I think. It could be good for learning TCP/IP, as it's 
very basic. :)

why is it that those Hex error numbers got me all warm and fuzzy 
when I saw them?   :-)

http://www.returninfinity.com/baremetal.html		Quite interesting OS 
Kernel stuff.

Robert - what do you think of L4 microkernels? Written in C, platform 
independent API, BSD, comes from Germany :-) http://en.wikipedia.org/wiki/L4_microkernel_family
Qt 4.7 is out. It sports QML, a declarative GUI definition. So far 
JAVA FX was the closest match for declarative VID. But JAVA FX is 
pretty much irrelevant. Qt is much more important otoh (my opinion) 
- now you can look at the examples - VID's no more unique - now even 
monkey can code in Qt, and get kind of cross-platform :-)

return infinity is quite appealing  :-)
OMG !!! 

As of the current version with the full CLI and internal functions, 
the operating system binary is only 16384 bytes. 


A standard "Hello, World!" example compiles to a file of only 31 
bytes.

Don't tell Carl about return infinity, he'll think REBOL is too bloated.
Qt has some really nice ideas in it. Note the importance they place 
on being able to create slick GUIs, but with the note that business 
apps only need a little slickeness around the edges. And the prominence 
of a state machine engine at the core.
Maxim

I also thought the guis looked a lot like rebol.
Graham

Anything we can use?
Was this an open source development or a Nokia team that did this?
Gregg

It's C++ oriented, but they have some new higher-level stuff. e.g. 
the declarative UI dialect Petr mentioned.

Qt was developed by norwegian company Trolltech starting in 1991, 
and was acquired by Nokia in 2008.
Pekr

How big is the package? I do remember some talks about using Qt as 
a potential View replacement, but IIRC BrianH expressed, that integrating 
Qt with REBOL would be difficult.
Geomol

[5197x2]
You can look at http://qt.nokia.com/downloadsand choose "Go LGPL". 
A few 100 MB, it seems. But there are many modules: http://en.wikipedia.org/wiki/Qt_%28framework%29#Modules
Maybe only a fracton is needed?
*fraction*
Graham

Was the thesis that integrating Qt would be more than writing R3gui?
Henrik
22-Sep-2010
[5200]
starting in 1991... ok, if we are allowed to develop on the R3 GUI 
for 19 years, we can probably get pretty far :-)

I guess the FInns are smarter ... as they just buy up the programmers 
they need :)

L4: Well, it's interesting and done by the university in the City 
I live in. So, no big deal, to get in contact with these guys.
With host-kit I would like to see a baremetal version of R3 :-) That 
would be extremly cool.
