b)Capacity on already assigned spectrum allocations is running out... fast... most of the countries with more than 40% penetration have this problem... 3G main reason is to extend that capacity
c)3G runs (Up to release 99 of the 3GPP) on top of ATM, ATM offers unmatched QoS and bandwidth management, it may move into the pure IP arena some day

Actually, there was an Urutsukidoji (Legend of the Overfiend) game released for the PC in 1992/93... game was one of the original batches of "Multimedia" (a.k.a Myst based) games, gameplay sucked ass, but it did feature some nice drawings.
When the Hubble first went into orbit everybody complained about it being a shot lived project yet it kept going, when the lens fiasco was discovered all the negative press that followed didn't derail the hubble project.

Sorry, but just looking at the sketch in the article one can see it's more of a theory then a practicality. 12 flat floors held up by columns with standard office blocks & parkland on each floor? Why not combine the columns & the buildins for efficiency/stabilty? Plus what's with all of the wasted space? Nobody builds a couple hundred stories in the air only to use a dozen floors & then allocate 50% of that floorspace for greenspace.
You forgot one thing... buildings are designed by architects, architecs and efficient use of space have never been together in the same sentence (Until now).
H.323 was never designed to handle security, nor were H.248 or H.245... those are signalling/encoding protocols...
What you are looking for is the next generation VoIP signalling protocols, be advised that not all of them handle security, that is supposed if you stablish a VoIP session you should do it over a trusted encrypted tunnel and so forth. Also note that some are designed to be used in tandem, no single protocol will suffice. Have a look at:
Yup you're misreading... those are the Hopping Sequence seeds... you can actually adjust the hopping pattern as you like (I used to do it with TAL/RDC equipment for Wireless MAN deployments when a DSSS radio got in the way... the ISS band can be very busy sometimes:)
I agree with you, FHSS is harder to intercept but not impossible... so instead of whining about how insecure it is, use the means available to add security over insecure channels (IPSEC, PPTP, VPN software, etc).
First time I saw that technology was on the Atari VCS 2600... the controller was called Headmounted controller or Thought Controller IIRC, but as soon as was demoed it quickly fell in Vaporware territory.
Yup, digital communication systems don't SEND clock signals over wires or air, but they DO USE clocks, clock is regenerated from the signal encoding (RZ, NRZ, AMI, HDB3 or Manchester) and fed to the rest of the system so when you decode the signal you know where the transition from one bit to the other is.
Not all encodings represent the transition state with a voltage, RZ and NRZ are basically TTL signals (GNDVcc), Manchester, AMI and HDB3 are differential logic signals (-VeeGNDVcc) and do represent phase transitions with a different voltage...
Remember, telecomms and computer science are different beasts so circular logic doesn't apply here...
Well no one does... but this comes from a totally different background... Problem is if you've been following events in Australia, the coalition is in a very bad shape after losing WA and Queensland, pressure from reducing oil taxes and a significant number of screwups in the past 12 months. The coalition goverment is very much on track to make Australia attractive to investors at the expense of the public, problem is... that's not working simply because most of these new laws affect the IT industry which the goverment hopes will come in droves to Australia.
So really, they don't care if laws reshape society or not, their main aim is to attract investors even if it backfires. Australia has done well in the recent years because it wasn't so restrictive... we'll see if this has the effect of making the country more attractive to large corporations or fuels a personal liberties revolt in the IT industry.

Whoa, Intel fanboy stop yer horses... can you tell us where did you get the "92.815% x86 compatible CPU" result? I mean, exactly what the remaining 7.185% is? Oh, you mean SSE? those instructions that supposedly made "your Internet experience faster"
Sad thing is that the Athlon has proven to be a very capable and well designed CPU but people have more fun bashing it than learning from the design... you must be the only one who bought a P4 because at 1.4GHz that's supposedly faster...
Oh, and the Slowlaris joke... well I don't like it (Solaris) but in case you didn't read, the Cobalt servers use Linux (At least for the time being)

Long ago, before Jobs canned it, one of the classic Newton markets was the vertical/health market. Lots of software companies offered software to doctors catering from patient tracking, medical records to digital books on procedures, information and diagnosis. Most of those companies switched to Palm as soon as Apple closed Newton Inc.
All in all is good to see the technology and uses getting some public recognition.
I'll put it this way: if the baby bells can't give a soccer mom a decent Internet connection without fouling up somewhere, then why trust them with a high-speed, high-cost connection to your servers?
Err, there are other options including (but not limited to) MCI, Sprint, GlobalOne, GlobalCrossing, 360 degree Networks, etc.
What's that? You don't care about the DSL woes because your T1/T3 is doing just fine? Then maybe you should think about how the baby bells are keeping their prices high while other ISPs are offering $900 to $2500 per month for a T1. However, you still have to go through a baby bell to get the T1/T3 line.
To be honest this is the dumbest post I've ever read about telco pricing, let me tell you that if you take a medium to large city, deploy fiber (Let's say 6 30 Km rings) plus the necessary SONET equipment, ATM switches, IMA concentrators plus the outside copper plant and you've got yourself an investment around $60 million, now depreciate the equipment over 5 years and add the oretain and maintenance costs and you'll see why a T1 costs as much as it does, at least with Cable and DSL you can oversubscribe and recoup the investment faster which means a lower price.
Oh, BTW the 53K limit is in place so you can actually use the other wires (The ones next to yours in the neighborhood FXB) for other forms of communication without cross-interference.
with the added bonus that we weren't ravaged by war every decade or so
Err, the US might have not been ravaged by war every decade but it's the only country in the world who has been actively at war be it directly or indirectly on almost every decade since the civil war, may I remind you of:
-War with Mexico (To get Texas, just imagine how happy we could've been without Texas today;)
-War with Spain (For Cuba, go figure)
-WWI
-WWII
-Korea War
-Vietnam War
-Guam, Grenada and Panama invasions
-Gulf War
-Balcan Wars (Where the US stood with their arms down during Bosnia and then fought in Kosovo, which I still don't get completely)
Big problem with that is that nowadays most people forget that and think that the US is the most pacific nation on the earth...
BTW, I moved out of the US in '89 and landed in Venezuela, trust me... you can do far worse than the US.
If you're intelligent you can rise from rank 1 (Grunt Coder) to rank 4 (Manager) and influence (In a positive way) your group... Do you think you're going to last 10K years coding? Teach someone, help the develop that's what a manager's really for, unless you want to submit yourself to the stereotype of managers being dumbasses who wouldn't know a DIMM from a CD.
The reason they offer that possition to him is because he understands the company and they want someone who won't disrupt the flow of things. If he still wants to code he can take on any of the countless open source projects lying around and help a bit (He can do that during office hours and tell the upper crust that "you're reviewing some of the project code").
For crying out loud... akira was a great movie (As were Ghost in the Shell and the Nadesico OAV -not the TV Series-) but hardly qualify as classic Anime. You need to check out the original Gundam series (Including 0080 and 0083 and if you're extremely lucky Gundam X and Gundam Z), and everything made my Go Nagai like Mazinger Z or Kotetsu Jeeg and if you consider yourself extremely lucky try to find Uchu Kubo Blue Noah or the original three Robotech/Macross series (You'll then understand Nadia Secret of Blue Water better:)
For those who want something really weird check out Ogon Bat (Search the web for Fantasmagorico), Captain Future or the 1000 year Princess. I even saw some Japanese adaptations of classic western tales like snow white, cat and boots, cinderella, etc. which were supposed to be for children but that were really creepy.
Gee, I remeber when I moved from the US to Venezuela they had like this huge tradition of showing Anime everyday on almost every channel, that's where I learnt about the real classics.
