Jens--that's an awfully nice piece of work on the web-site that you pointed me to.
Thanks. I hope your 'lost connection iPhone-->mac gets resolved'. Oh, and I
couldn't overlook the 'iPhone build entry'. I'm kicking myself for missing out on
the iPhone dev stuff. I downloaded the SDK and I even own an iPod Touch, but
I'm trying to remain focussed on establishing a neighborcentric desktop. Even
this 'triangulating webcams' is a distraction--albeit a pleasant one.
I was thinking of initially pointing three cameras at a rubik's cube--using the cube as a totem. I was thinking front, right, left placement--90 degrees, 3-4 feet away. I was wondering how to modify the 'fast user switching' transition, so that it would animate in the same direction as the rubik's cube, but limited to fixed axis, perpendicular motion--i.e.--rotate in 4 directions left, right,up(forward),down(backward). Currently, fast user switching corresponds to only 'left'. This might be a good start. Who knows,
later, maybe after lunch, I can have them triangulated over a larger scene with more freedom of movement. I have hopes of freeing myself from a really cheap
mouse (it was free--included with the iMacs) and doing exercises--keeps my neck from getting stiff and I have trouble sitting still when I hear the great stuff from iTunes. I don't know about the rest of you, but little Roscoe, my anime chimpanzee fell off his chair the first time that he looked at the fast user switching--"hey where'd that go?--well, he didn't actually say that, but I could tell that's what he was thinking.
Stefan--thanks for your reply.
I would agree with you totally. 10MB, in the present context of this brief conversation really is not small--but, if you'll forgive my poetic license, it's
smaller than it was yesterday, bigger than it will be tomorrow. Capt. Grace Murray
Hopper gave a wonderful lecture illustrating a related point--or so Gramps tells me.
Gramps tells me that 10MB would have been 60 boxes of 'punched cards'.
My dad tells me that this was the capacity of the internal drive on the Lisa.
A 10MB hard drive today would be considered miniscule, but, since I was
mentioning 'strings'--one would have to spend a long time at a keyboard before
generating a 10MB text message. I don't think that the entire archive of textual content of this rather active list comes anywhere near to 10MB.
By the same token--an uncompressed 1920x1200 32-bit screenful of pixels is
close to 9MB, by my calculation. (A picture is worth a thousand words...hmm.)
Some Hollywood stills are "beyond words" and these have provided me with
great personal pleasure--I am hesitant to share these with friends because of
copyright restrictions.
I was thinking of moving the rubik's cube off to the left, outside of my desktop. I may
convert it to a shrine with appropriate controlled lighting, so that I can't ignore where it is currently positioned and to ensure that my el-cheapo web cams can
detect its orientation, hopefully with minimum latency. I don't know if it will match
my expectations--I've never tried this before. I have decided against using MPI.
I believe that's a small letter 'b' in Gigabit, so it's really ~120MB. I have no reason
to doubt you when you mention '1 sec,'' even tho this is slightly slower than the
'theoretical stated Gigabit maximum (more than a factor of 10).' Personally, I doubt
whether even this speed could be achieved without a constant connection (NSStream? and sockets?). This (local network performance) is an area in which I have very liittle practical experience. I just installed a time capsule last week and I've been doing some preliminary testing. As a matter of fact, I know so little about
network details that I've just checked my 'switch' and noticed that it is labelled as a
'eight port 10/100Mbs Ethernet switch'. Is this "Gigabit" ethernet? Time Capsule,
G5 iMac and all my mac minis support this, so this is the last 'X factor'.
Well, I'm signing off. I just heard the lovable Gov. Schwarrtznegger say in passing, as if it was common knowledge, '...since California is the most important state'.
I mean, he didn't even bother to say "arguably,' so I won't argue nor quibble.
How come I'm not from the most important state? I want to be from the most important state. Whatsa matta wit Illinois? (hint, the 's' is silent--Illinois does not
rhyme with 'Beach Boys." It does rhyme with 'please don't annoy'. The correct
pronunciation (it's a French word) is probably closer to illy-nwah--but that certainly won't get you any street-cred anywhere on this planet:-)
Sorry for any comments that were 'painfully obvious'. I welcome any 'debugging' of my statements--I always try to practice
egoless 'programming'--this is very hard--generally it runs contrary to human nature.
Again, a most sincere thanks for the people who took time from their busy schedules to comment. I wish I could express the pleasure that these lists do afford.
