There's no business case there. No customer would willingly pay to upgrade, pay more for the ISP to upgrade their bandwidth and get... a more limited and failure-prone system than they have now.
What you've describe is workable - but again you're severly limited in the total channel number as it's limited by the smallest connection in the network. With a caching system, as I've described, you're only limited by the customer connection to the ISP in channel count. You could schedule caching update during off-peak hours and provide a more secure system.
I think the other question is reliability. Multicasting is inherently failure prone - as it depends on a very reliable network to reach all customers in near real-time.
Lastly, the security of the video stream is questionabl. Multicasting requires a "broadcast" of packets - providing an easy target of attack. Caching would be directly addresses and take advantage PKI without a single key point of failure.
Google has machines everywhere - I'm pretty sure they have similar capabilities. I'm not sure about Yahoo, but I believe they've got a number of servers out there in the world - mostly at large hosting facilities.
Well I cut my teeth on secure server deveopment over low bandwidth, got the tshirt and the patent to prove it, heheh.;-)
This model they want to deploy is hard to get right. And I don't believe it's the solution for the midterm, especially when you start promising on-demand and HD quality. If you calculate the bandwith for 32 channels, multicast, at 24x7 versus on-demand caching - there's no comparison. Multicast would greatly increase the base bandwidth required to operate an ISP.
I've spoken with a few engineers in the IPTV business... they're al about multicasting and QOS delivery. I'm going to go out on the limb and say... uhhh.... no. Why?
Because that's NOT what internet TV is all about. Sure, for some content think it's great. Like ABC, Fox, whatever - they can do the multicast. But for the rest of the content providers, it's going to be on-demand. And that solution is really quite simple. And it makes money.
Basically you take an Akamai like model and extend it. Deploy caching servers right to the ISP's - on the customer doorstep. Offer subscriptions to the customers and the ISP gets a chunk of the monthly. Customers get instant access to the content from the caching server. Content people get a chunk from the number of views statistically. ISP's only have to move content over their uplink once for all their customers nearby.
Best part is you could do it securely for the media providers, and give people a reason to use the service (more shows, better quality, faster delivery). Eventually you offer sell-up items like movies, sporting events, etc. In other words it would be better than cable, cheaper than cable, and far cheaper to operate.
There's all kinds of great stuff you could do here - and you could do it on the cheap and make beaucoup bucks. So, ya know... send me a bag of gold hehehe.
While your comment on the Itanic is partially true - the real reason it failed was the VLIW premise.
Executing multiple instructions within a single "opcode" - and then developing a compiler to pre-determine the best path was about the STUPIDEST idea I've ever heard. Just think about it... a compiler has no idea about the REAL conditions at runtime.
A compiler can optimize a single program thread - but can't optimize for multi-threading, multi-processing, or mixed mode execution between the OS and the application. All these things depend heavily on hardware - and Intel/HP made the hardware as stupid as possible in the places where it really mattered.
They optimized for a problem (one instruction per cycle) which was easily overcome with parallelism (smp or multi-core) and faster clocks. Instead they choose the most complex assumption (multiple instructions per opcode, with different possible results) and sits heavily on an overloaded branch-prediction unit which is partially implemented in the compiler.
Itanium has improved and I'm sure they'll be around for a few more years. If Intel had been smart we'd have 8 core Alpha chips instead - as they own the Alpha intellectual property.
Well, gee what about Shakespear, Bethoven, and Mozart? They actually were brilliant, and their works have lived on for hundreds of years.
Those albums are great - but I doubt they'll be playing 200 years from now. I mean, how often to you hear "I've got a lovely bunch of Coconuts" on the radio?
Tell you what.. go down to walmart and buy a Cingular ToGo plan - they'll sell you the SIM chip for 14 dollars (which includes 14 dollars of talk time too).
Stick the sim in your RAZR and give it a try. If it doesn't work you're only out 14 dollars - of which you got to use for calls anyway.
Coverage is going to be different for EVERY location - and it has more to do with tower height and placement. Also I've had specific model problems(v300, v55x) Motorola's from a year or two ago seems to have degrading GSM problems - signal connections on the phone wore out and broke. RAZR doesn't have this issue.
It's somewhat funny - I remember having this exact discussion with my genetics professor. I was a chem major who is now a developer.
It seems to me that DNA/RNA is "machine code" and data which runs on the laws of nature. It's a layer removed from silicon design, more akin to a self-modifying FPGA.
In other words we're so far only looked at the boot code and associated data. The "program" is what we were calling junk.
And it makes sense - if you think of the program as a massive recursion network which builds common parts (stem cells) and then organizes and specializes.
I know that's a simple bastardization... but perhaps I've just looked at too much dissassembler. I will feel a little vinticated if this is proven.
The reason it doesn't appear to work is the output happened before you even ran it, unless you didn't run it, See??.... Look in your shell history silly man...
Southerners... you mean like NASA (New Mexico, Alabama, Texas, Florida), Petro&Gas, NORTEL(Dallas), IBM CPU design(Austin), Texas Instruments (first integrated circuit)
I could go on, but obviously, Southerners are engineers too. Just beware of Southern politicians.:-)
Great link! I've always wondered if someone had actually done that.
I say worse than coal or nuclear only because if we seriously became a PV economy - the efficiency of PV is so low that it could never replace traditional generation in the end.
I like the Stirling engines, the biomass/algae systems, and of course wind. The obvious problem is that we can't scale these systems right now to match what is already available. With time, I'm sure we can do better.
Well, I'll give you my advice. If your mental breakdown is neuro-physiological (bipolar, schizophrenia, acute psychosis, or the like) then you need professional treatment. Stick to your meds as prescribed - you really do need that psychiatrist. Don't take this advice without professional help to evaluate your situation.
BUT... if you're otherwise mentally healthy, but simply hate your job - then get out of there. Your mental health is worth FAR MORE than any money you'll derive. You will end up driving yourself further into that hospital.
I'd guess your problem is fear. Get over it. You will eat if you're willing to work. If you're a believer, believe that you will be taken care of.
I once lived abroad(Europe) on practically nothing. Took a semester off from college. I never compromised my morals - though it was a huge problem over there. I did eat everyday, slept in a decent bed, and never lacked the basic necessities. I never borrowed or bummed, nor did I get handouts.
I had a laptop, scanner, and an musical instrument. I played music in jazz clubs on weekends, I did a little computer work - which was mostly advertising at newspapers. Sometimes I tutored C and Unix development at the colleges (HEC & UParis). You run into people and find their problems - if you can solve them then a lot of times they'll pay you for it or exchange services like free printing, or better yet a free meal. Make sure you arrange the payment terms before you start working if it's professional work.
What's stopping you from doing what you want, really? Nothing but yourself.
After 9/11 the bank I worked for failed - so I demolished houses and dug ditches for a friend in the construction biz for a little money. It was fun work, honestly. My wife really respected me, as normally I'm working on high-end clustered software development. Be flexible.
Stop sitting there moaning about life. It's outside your door. Go out, talk to the neighbors. You think they don't have the same problems?
"About one in four adults have the symptoms of at least one mental illness every year, and nearly half suffer disorders during their lifetimes, according to the study of 9,282 people published in the Archives of General Psychiatry."
Find people like yourself. Golf, play tennis, join a club, take another job if your situation allows. But for heaven's sake - don't sit around and worry about the neighbors.
Making silicon solar panels isn't environmentally friendly either. In fact I'd venture that the environmental impact is as bad or worse than coal or nuclear. The amount of power, just necessary to make a solar panel is probably as much as it generates over a few years!
That said - I'm still a fan of Solar for limited applications with low-power requirements which replace chemical batteries. I'd rather see wind power and hydro for most household/industrial use - as it's much more efficient.
They GIVE you the damn number when you buy the disk! It's right there, on the disk, along with all the keys you need to watch it. How in they hell did they steal it?
I worked for the company that sold the 9/11 hijackers their hotels. Could we have stopped them? What about American and United airlines?
How far will the polemics go? There's fair laws for the posession of guns already.
People need to stop focusing on the things and start helping those who are ill. It's obvious that Cho was mentally ill. It looks like many people did try, and some attempts were successful. But really - let's get wicked and blame the people who are, in my mind, really at fault:
1. The university knew he was in deep trouble - several teachers and students reported many, many problems with the poor fellow. Why was he still there? 2. The family weren't informed or simply ignored (I would assume) a huge number of problems in their son. 3. The mental health community, Doctor's, Counselors and Psychologist apparently didn't follow up on Cho. 4. Perhaps the insurance company was at fault here? Did they pressure the mental health workers to "get him well" without a thorough investigation?
Really - guns, while they were the final horror of this situation - had little to do with why Cho went *snap*.
Are they funded by the BoogeyMan? Perhaps Santa Clause? I think it's a bit of a "diss" to use a couple of articles to paint Z's project... it's clearly stated on the Developers page:
"This work was, in part, supported by the National Science Foundation under Grant #0238305 and by the Department of Energy."
Of course ISE has numerous clients and sponsers as well. Just check their webpages.
Selling them commercially will have little effect here. There's already demand for low cost machines - without the XO on the market. If anything, having a commercial version available will put downward pressure on illegal reselling of the machines - because those that can afford to buy them legally will probably do so.
Seriously though... 10 years ago I could scale to a hundred threads pretty easily... what's so difficult about a few thousand threads on processors that are thousands of times more effecient and faster.
The issue isn't can I do a thousand threads - but can I do it simple AND effeciently. The answer is no - unless you know what you're doing. There is no "general model" that fits. Or you use something that already has a good model and your problem fits in that model.
Really though - I've been wondering if there's just a tad bit of "professional jealousy" going on here. I don't have the background to prove or not prove any of D-Wave's claims - but I still give them a high chance of success.
They're committed individuals who are sticking their necks on the line. They went from mixing chemicals in a jar and shooting lasers in a lab to a working prototype.
If this venture fails - I don't see those guys making much headway for a number of years. If they're successful - all the naysayers can say is "oops." I'm hoping they are successful - but of course I'm a software guy with lots of uses for such a device.
$600 IS too cheap if demand and supply are balanced. When demand drops, I'm sure the price will go down.
The point of the PS3 is to have a next-gen on the market - it's not to destroy the already existing market for the PS2 and PSP. They get more time to work out the kinks, work out customer demand, change any non-working foibles before they commit huge resources rolling out something millions of people don't buy in the end.
When you're the market leader - the worst thing you can do is throw out an inferior product, sell millions of them, and then loose the market through stupidity.
Ya know, I get tired of drumbeaters like you. You know jack about our citizenry if your entire experience is through an electromagnectic pulse, whether it be TV, internet, or what have you. You know jack about our citizenry from a trip to Vegas, or a dude ranch in Wisconsin.
America makes mistakes, fine. We have bozo's for President (not just bashing Bush here, honest). Those bozo's go about bombing nice places into ruins, making new bin Ladens across the world.
But that's not the citizenry, any more than saying Germans are "little Hitlers" or French are "all fags." Yes, you can find examples of that a plenty. I can also watch French TV mock Americans for 3 hours every Thursday. I can watch German TV wail about pacific island Nukes and Guantanamo bay. I lived there - and I can't really guague the feeling over there anymore. Just because you experience some narrow media-driven sliver of American life - doesn't make your statement right. Just because you chat on a billboard amongst a rats nest of 18 year olds looking for 9/11 revenge doesn't give you that experience either.
It just makes it pathetic - because you're really just buying the cheap lines that Rupert sold you. What you don't see is the citizens who are aghast with you. What you don't see is the totality of the situation - and you only get that by living here, breathing the air, talking to the cleaning ladies, chatting with the neighbors at the game.
I've lived abroad, was born abroad even.. you just can't understand a people from a distance. So really.. please stop being a pathetic ass, wherever the hell you're from.
Eh.. all very complicated ways of "demonstrating" the very simple effect. I have a much simpler explanation.
Imagine you have two very long garden hoses - one is empty (air only) the other has standing water. As you connect each hose and turn on the water - you'll see the water sprays almost immediately in the already filled hose - whereas it takes a full minite to fill the other hose before water comes out.
This is, essentially, the same thing. Just replace water with photons.
