Re:Yeah, butUh, no. Transistors were invented as amplifiers, not as switches. Only later were they used in computers.

Re:Dark Fiber gaffe or proper planning?
Most of "dark fiber" articles out there fail to see the same rationale behind the large amount of dark fiber out there. This is proper planning. Network traffic has been doubling every two years or so, this means that 90-95% dark fiber would last you about 6-8 years.
Not sure about the network traffic doubling every two years. I seem to recall that it's a mythical number that MCI came up with at the beginning of the Internet age.
But other reports I've found indicate that network utilization is doubling every 3-6 months. Yikes. Don't know if that means that the dark fiber can now only last another 2 years assuming it gets turned on or not...
This is perfectly sensible. In fact, if we had to rebury fiber within 6 years of paying billions to rip open downtown Manhattan I would fire my provisioning manager.
I think that you assume one thing, and that's fiber technology does not improve. Assuming that the technology doesn't change, and network traffic is doubling every 2 years, then the capacity will only last 6-10 years or so. But if the transmission equipment gets faster and allows greater capacity through the current fiber, then the life will be much longer.
Assuming new systems utilizing 64-channel dense wavelength division multiplexing (DWDM) as announced on Lucent, then this potentially allows 2.56 Tb/s per fiber. Doubling the channels to say 128, now means double
the capacity, while using the same fiber.
As long as fiber technology keeps improving, then there shouldn't be a problem with running out of bandwidth, since the fiber is virtually upgradeable forever. -
Re:It's turtles all the way down.First of all you cant take pictures of atoms. Light of the wavelengths we see cannot give us a clear enough picture. Once you start putting enough energy into light to get the waves small enough to see whats going on the Heisenburg uncertainty theorum kicks and and its all useless info.
Who said that a picture has to use light? Anyway, we have taken pictures of individual atoms using optical photography.

Privacy Director / Privacy ManagerSome of the Baby Bells have a product called "Privacy Director" (BellSouth) or "Privacy Manager" (SBC's companies including SW Bell, Ameritech, PacBell etc) that is great for this.
Basically this is a very smart version of 'block anonymous calls'. Instead of just blocking all anonymous calls, it routes them to an intercept message where they can unblock their caller ID (if it is deliberately blocked) or identify themselves verbally. Only if they follow the procedure does the call go through, and you still get the opportunity to screen it when your phone rings.
Here's the best part, which they don't really advertise. Since most telemarketers use automated phone dialing systems, most of the calls never make it past the intercept message! The automated dialer thinks it hit your answering machine and hangs up. So your phone never rings.
I found that once I turned on Privacy Director on my home phone, the number of telemarketing calls I get has gone down like 90%. And I never had to hassle with anyone, register on a list, or anything. Plus it makes Caller ID all the more useful because you never see "Out of Area" or "Unavailable" anymore.

Re:Are you kidding?We work with them all the time, and have for years. One of the earlier supported gigabit fiber cards is the Alteon AceNIC, with the driver being written by Sorensen in 1998 for Linux. Here is a list, more current (no by any means comprehensive):
- 3COM 3C996-SX, 3COM 3C985B
- Allied Telesyn AT-2970SX/2SC Dual Link1000BaseSX, 2x SC fiber
- Asante FriendlyNET GigaNIX 1000SX
- Compaq NC6136 Gigabit Server Adapter
- D-Link DGE-550SX Fiber Gigabit Adapter
- Farallon PN9000SX, HP 1000BASE-SX Gigabit Ethernet LAN Adapter
- IBM Gigabit Ethernet SX Server Adapter
- Intel PRO/1000 XF Server Adapter
- GA621 NetGear Fiber Gigabit Ethernet Card
- SMC SMC9462SX Tiger Card 1000
- SysKonnect 1000BASE-SX PCI Adapter
- Toshiba 1GB Ethernet Adapter.
Many of these are on the second or third revision of the card. I have found the "Tigon 3", Broadcom 57XX (5701) (tg3 and bcm5700, supported in FreeBSD, Linux, and others) 3COM 3C996 (SX and T) to be a very good card, the best of the bunch, as it has advanced packet coalescence, checksum offloading, and has the least number of interrupts with even insane amounts of malformed/attack ingress traffic. The medium seems to make little difference in the short haul.
I have also seen single mode cards for PCI, and I have also been working with single mode POS OC3, OC12 and OC48 cards for PCI.
POS OC3/OC12 for PCI here , Lucent OC12 and OC 48 cards here, just to name a few.
So, with OC48 being 2.5Gbit/sec, I think PCI/PCI-32/33/PCI-64/66 and PCI-X 133 have all seen their fair share of gigabit speed. Most of the cards listen above work rather nicely.
Now, one should use fiber wherever possible, especially for longer hauls. I have OC3 long haul cards for a 7507 at work that are rated to go 80Km in single mode. Multimode fiber transceivers and go up to 500 meters. Consumer grade fiber cards can go up to 10,000 meters as indicated by this 3COM article.
The point? Backbones are best done in fiber. Most switches support fiber, often they have removable transceivers or cards that let you pick single or multimode. I think that its easier to guarantee throughput with fiber as well, as RF and other interference doesn't play a role, and more often than not you aren't even coming close to the limits of the fiber in terms of distance.
Copper GigE is a good cheap fast short haul way to get servers hooked up to your switches. I have never had any problems using regular CAT 5e, and CAT 6 cabling demands a premium and isn't clear what the benefit is in terms of throughput. As far as better "CATS", I don't think they Spec for CAT 7 or any others has even been drafted, so its mainly marketing drivel at this point.
You will be surprised to see that these cards can all feed PCs far more information than they can take, and you will often see disks trying to keep up, and in certain interrupt driven kernels, if you put the adapter in promiscuous mode (we do this to analyze traffic) you can create kernel live lock because the driver desperately needs to poll the input to prevent userland CPU deprivation.
Again, not using Fiber for backbone is not a good idea. The cost differential is not as bad as it used to be, and you can by most any length of pre terminated SC and LX fiber. In fact, the interesting thing about fiber is the length of the cable barely affects cost. A 10 meter cable and a 100m cable are usually very close in price. It's the endpoints that cost the cash. -

Re:The way I see it..
FWIW, according to Google:
"right-wing libertarian" = 641 hits
"left-wing libertarian" = 231 hits
It's worth about.... nothing.
"left-handed person" = 65,700 hits
"right-handed person" = 41,400 hits
Are you going to infer that more 'persons' are left-handed? Maybe a more logical conclusion is that a "left-wing libertarian" is what Linguists call 'marked', which is when a less common (or less expected) characteristic is mentioned whereas the expected case doesn't need to be specified. Another example which shouldn't require Google is "A bird which can fly" vs. "A bird which can't fly"; which phrase do you think is more common?
As an aside, this ties right into Information Theory (as applied to Linguistics) where the amount of information in a statement is inversely proportional to the 'expectedness' of the information. At least that's the basic idea; I'm sure someone else here will correct me or explain it better ;-)

Re:good link
Nonetheless, the brain can store an amazing amount of information. Remember, according to information theory, data and information are two completely seperate things. Information has one key element that data does not, that of meaning. Claude Shannon in his historical paper on information theory deomonstrated both the concept of information and compression with the sentence: "only infrmatn esentil to understandn mst b tranmitd." The data when taken as is, has no meaning, but when intellegence is applied the sentence is easily understood as "Only information essential to understanding must be transmitted." In the same manner the intricacies of movements such as dance are not thought of a move by move basis by an advanced dancer (although that is how they are learned), but rather as a natural movement to peroform, say Irish Step Dancing or the Polka. Yet initially each movement is learned, thus in a data sense the full data is entered and the brain does in a sense compress it as it is used. So what does this mean, that we continually decrease the amount of "stuff" stored in our brain. On the contrary, I would suggest that it is the brain's way of making room for more information as we continually learn. As a former pre-medical student (I turned to the light side and became a CS student) I am continuously amazed by the intellegent design of our brain the more I learn about it.

Re:The Meaning Of It AllWhat is a good source for Theory of Information?
Start here, this is an introduction.
Then, beyond any doubt, you should read Shannon's original paper, published in 1948. There is some math involved (the course is normally taken on 4th year in a University), but don't worry.
Snannon's 1948 paper, and Kotelnikov's math (from 1933) laid the foundation of the information theory as we know it.

128000 Mbit , i.e. 128Gbit to reach speed of light
Not bad, considering there are at least 40Gbit commercial links.
Another story is that it has to go through internet, not just link.
And routing 128Gbit of traffic is not easy.
Here's where Lambda router comes in play ;-) -
Re:He isn't talking about Ultra Wide Band?
But techniques like Spread-Spectrum and Ultra Wide Band are precisely those that will allow radio channels to be utilized most efficiently, almost up to the capacity limit predicted by Claude Shannon and Information Theory over 50 years ago. "Traditional radio technology" does not offer as much room for improvement, certainly not as much as would be required for the kind of "Unlimited Airwaves" that Dan Gillmor predicts could exist.
For example, a proposal for near-infinite frequency reusability based on spread-spectrum techniques, is given by Steve Shepard. -
More info of the fraud
This was submitted yesterday to slashdot, but not posted for some reason...
For the past two years, a team at Bell Labs/Lucent, led by a young physicist named Jan Hendrik Schon, has published a dizzying array of groundbreaking work in the field of solid-state physics, which has previously
inspired discussions at Slashdot,
here
and here.
However, as reported tonight in Science (look under
the "ScienceNow" link), and I'm sure soon in Nature, it may all be a fraud. It looks like Schon has used identical data curves for very different experiments in different papers. The scale of the deception is enormous--there are duplicated graphs in at least 5, and as many as 20, papers. The fallout from this will be huge, not just for Lucent, but for the physics community as a whole, as a large number of these papers made it through the review process at the two most prestigious journals in the natural sciences, Science and Nature.
For a comparison of two plots from two seperate papers about two seperate experiments with remarbably similar data, check out here here. Scroll down to thursday may 16...

IPv6Interesting moot point... it seems that 3G licensees were going to require IPv6. Search for "IPv6" on various corporate and info sites:
- 3com - no listings (no support???)
- Cisco Systems
- HP - no listings in network equipment
- Juniper Networks - OS support
- Linux IPv6 HOWTO
- Lucent - interesting
- NetBSD IPv6 docs
- Windows XP - Installing IPv6
- RFC 2492 - "IPv6 Over ATM Networks"
This long annoying sentence here to get around an annoying slashcode bug, because it can't count.

Re:you will notice what the BSA doesnt do..
Funny, isn't it? I reported Lucent Technologies to the BSA for piracy last year after seeing CDs full of unlicensed software being used for system installs there. If the BSA raided Lucent, the press sure was quiet about it.

Commercial product
Lucent's QIP has been around for 5 or 6 years and is pretty good for centrally managing address space. At a former employer we used it to manage a
/8, a /24, and numerous RFC-1918 subnets for a network spanning a couple hundred sites in a few dozen countries. Runs on NT, W2K, HP-UX, AIX, and Solaris. (Disclaimer: I am not now, nor have I ever been, affiliated with Lucent.) -
FCC vs IEEE
The distance will be effected by how much power the FCC will allow us to use in this frequency range. It will may vary from country to country. The IEEE Standard covers how the thing is going to communicate between vendors products (Lucent and Cisco have to play nice with each other). The bandwidth allowed will depend on how many channels we are allowed to use, or the product will let us use. One GHZ channels should be able to pump DS3 or higher speeds...Let's keep our fingers crossed. I'll be happy to beta test any gear

Two possibilitiesI have worked in an environment like this and one of two things inevitably happened on each workstation:
- Employees spend large amounts of time circumventing the access controls. Some are caught and disciplined (though very infrequently). If the systems rely on Tivoli or some other sort of automatic updating, the "free" developers often need to copy software from their co-workers so that they have (for instance) the latest version of the development environment. After the restrictions are successfully removed, the programmer can usually go for several months before having to "defend" his machine from a recovery CD or otherwise tweak it to keep the controls out. Net result: productivity goes down.
- Or, the user learns to work within the constraints of the system. They are on a first-name basis with the administrative support staff, whose intervention is needed to change the system time or screen saver delays. Very little time is spent developing software and a lot of time is spent on trivial matters. Systems support staff all get large raises, lots of overtime, and increased budgets because of their heavier workloads, and less actual work gets done. Net result: productivity goes down.
The moral of the story is simple: programmers want to be free.

Re:Video != only need for broadband
You know... perhaps it is broadband. Just think:
1. feed high-speed data text to the video in
2. compress video
3. send over 28.8 line
4. decompress video
5. OCR out the data stream, and voilla. "broadband"
I wonder what Mr Claude Shannon would have said about this? Here's more info about the master. -
Re:Go ahead. Laugh while you can.
Bravo!!!
I played that game for the past couple of years - being a PHB-enabler. Things like:
- working 80+ hrs/week (no weekend free-time either) to restructure the god-awful business plan written by clowns so the PHBs could get that critical $50 mil to keep *their* business alive.
- fighting millions tossed at worthless vendors for every little PHB fantasy, like a $2.5 million "system to automatically download call records from a switch and change their format so it can go into the billing system" - that I replaced with a $2,000 Linux box, ftp and grep, only to see the stuff bought anyways and put on my budget while the PHB got a free trip to Disney on the vendor's behalf (never mind that theirs never did work despite several visits by just-out-of-college $225/hour techs).
- solving PHB-induced crisis after crisis with no fanfare, often using my own funds, contacts, whatever, only to prove to the PHBs that their incompetence has no consequence
Imagine their horror during layoffs when I walked over to a fully functional company I own that afternoon (hey, I saw the writing on the wall a half-year in advance).
I'd swear, they were mad at not getting the satisfaction of my agony. Somehow, they feel the need for people like us to suffer so they can rationalize that they're somehow of value.
It's time to destroy the PHBs. Withdraw your expertise. Don't give them your minds. Don't enable their parasitism. Brilliant tech people are a direct threat - we represent intelligence and reason. Don't underestimate or think for a second that they aren't threatened by us and seek our destruction.
Instead, be accountable for yourself - either contracting, consulting or building your own company with other competent people. Work only with other competents; don't enable or empower these parasites. It's time to slay the PHB culture.

Re:No DSL in the curb cabinet
-
Re: No BS - Frame Relay has been used with DSL.> Your second line about use of frame-relay is pure BS.
Bzzt. Several older DSL implementations used frame-relay from the DSLAM to the customer's CPE instead of the (now) more typical ATM. Take, for example, the Lucent DSLPipe product, which in its product description says:
| Support for Frame Relay Network Access Protocol.
Or what about the classic Copper Mountain CopperEdge SDSL Line Card, used by many of those formerly on NorthPoint's network:
| Standards Support
| RFC 1490 Multi-Protocol Encapsulation over Frame Relay
| RFC 1973 PPP over Frame Relay
| Multi-link Frame RelayI could go on and on. Lots of providers, at some point, have used Frame Relay in their DSL implementation instead of ATM. Plus, many providers (such as GTE) have used frame relay circuits to connect their DSLAMs to a central switch site to connect to external bandwidth.
I will agree, however, that it's not a particularly important point in the grand scheme of things. AFAIK, Ethernet encapsulation over frame relay has far less bandwidth overhead than, say, either PPPOA or PPPOE, so it's sort of a moot point.

Re:NASA phone homeIt could be that they are planning on using the phone for their telemetery and data communications. (at least a portion of their telemetery.)
CDMA service works on GPS provided timing. The phone has to be sync'd up to the gps system on three (we currently use three, but the technology provides specs for six) antennas in the phone. There is a fourth antenna in each phone right now, but it is for searching the network for your next cellsite.
Also, with a lauch date of six years from now, NASA may be thinking about the fact that 3G Cellular telecommunications will be availible. Data transfer rates right now are a pathetic 14.4 kbps. That will soon be changing. The first step CDMA2000 will move the transfer rate up to 144 kbps, and then full 3G will be at 1.44 Mbps.
Full 3G has been expected to come out for a while now, however there have been many delays in it's coming. Lucent has some information posted. But not the hard and fast facts most people will be looking for. Oh, and here is a cute picture of what they want as an all IP based cellular network.

Why YES!There are two options here:
1. There are plenty of telephony systems for Linux/Solaris that have APIs written in C. It would take only a day to interface these cards with Java via JNI. I've done it before. If you are doing VoIP only then I recommend Dialogic (now Intel) or Brooktrout. They are very inexpensive, especially if you need high port density (up to 96 ports per board). Brooktrout is offering great deals now, since they are new to the market and want to get some market share. If you are doing a combinations of things (Voice, IVR, FAX, VoIP) then try Natural MicroSystems. A bit more pricey, but they have a rock solid API that has everything you'd need. They also have an octel board that supports 196 ports.
2. Use a system built around JTAPI. This would be for VoIP only, since I know of no reasonably priced implementation of JTAPI on hardware that does anything else. (If you find one, let me know, I need IVR, VM and outbound dialing it for a project I'm doing). Here's a short list of JTAPI Implementations:Lucent's PassageWay
NOTE: I've priced the lucent system, the quote that came back was in the six figures!!!
JTAPI is relatively new, and the only people with implementations are those who helped design the spec. If my company decides to sell the implementation I'm in the process of writing as a package, I'll be sure to email you.

IT is the PR (Personal Robot)...Think about it, it makes sense. When I thought about what was one of the most useful things that I've always wanted, that is, a personal assistant...it simply makes sense that a personal robot would be very useful. Plus it would be the logical extension of the PC.
Also since the invention was described as replacing something "dirty, expensive, sometimes dangerous and often frustrating" it mean that it would replace a human assistant.
Also this kind of thing wouldn't be that far out since Honda recently demo'd their walking robot and Kamen demo'd his iBot. Also text-to-speech (http://www.lucent.com/speech/) and speech-to-text (http://www.lhsl.com/) software already exists. The hard part would be gluing the stuff together so that the robot would be easy to use and useful.
It would be revolutionary, fun, possibly cause legal concerns (what?!? have robots walking around?) and cities might have to be designed around them to give them a separate lane to travel from point A to point B.

organic chemicals aren't what you think they are
"organic" chemicals are not chemicals made by mother nature & sold in your health food store. they're not bacteria or any other biological system, including proteins. organic chemicals are exactly what the topic said : carbon based molecules. anything made of solely carbon, nitrogen, oxygen & hydrogen is generally considered organic. this would be as opposed to inorganic chemicals which contain metals, non-metals (like silicon) or either of the lanthanides or actinides.
when this article refers to organic chemicals it means stuff made in a lab by chemists & includes, as was mentioned previously, polymers, plastics etc.
the reason these systems are so interesting is their versatility. bell labs, uh sorry, lucent scientists recently showed some really neat behaviour in the anthracene/tetracene family (as in mothballs) including lasing (albeit at low temperatures, but you've got to cool most lasers anyways) & superconductivity. they've managed to build field-effect transistors out of single crystals of pentacene. all very cool stuff & some of it came out recently in either PRL or nature, ok now i can tell you it's science. if you do an authour search for batlogg you'll get a chronological list of what they've been up to. i will attempt to link the search results here (fingers crossed). you should be able to read the abstracts at least.
hope this clears up why organic chemicals have nothing to do with the organic world & why the NY times is so excited about organics.

also, I don't know where the "plastic" idea came from, but these lasers are grown out of tetracene, an organic molecule with four connected benzene rings that conducts well. When they injected an electric current through this, the light bounced back and forth between mirrors in the material, eventually producing beams of intense yellow-green light
there is nothing in the original release mentioning "emit light ranging from ultraviolet to infrared". From the official PR, "Because the current configuration of the Bell Labs organic laser operates at a visible wavelength, it is not yet appropriate for optical communications. "
In closing, how did this story submission get accepted without even a link to Lucent's own web page or PR page with the official release? Is slashdot now requiring only second and third hand information from such trustworthy sources as the NYTimes?

Related linksHad a quick look around and could only find current references to the Reuters story. Its on all the major search engines.
I did notice that these guys have been tinkering round with neural stuff for a while. I found this article which is interesting and along a similar vein and has a pretty picture in it, or here which is the press release without pretty pictures.
I off to book a holiday at Westworld now.

Re:Why is it called inferno?
Judging from the prominent (aka "big-ass") quote on their website, it was inspired by Dante's opus of the same name. It also fits in nicely with the name of the related programming language: Limbo.
