split loom tubing is what you are talking about. You can buy (albeit more expensive) from automotive supply stores in a variety of colours and sizes, or from telecom suppliers.
The ISP for which I work does no such packet shaping or TCP resetting one any traffic entering or leaving our network. Despite this, we have a median reset rate approaching 13%. Does this plugin take into consideration the fact that the reset could be sent from a foreign network rather than the provider the client is attached to?
Does the Vuze client track resets on a per foreign client basis, or as an aggregate of the local client.
Cable companies, not all but a good majority, are re-segmenting and pushing fibre deeper into their serving areas. This will allow for greater frequency reuse and provide more available RF spectrum for narrowcast applications such as data, VOD and Voice.
The article is a little misleading, however, in that it isn't bonding 4 cable lines, but up to four 6MHz channels providing up to 24MHz of RF spectrum to data use.
I had seen Cisco's pre-DOCSIS 3.0 implementation (at the time they were calling it Wide-band) at the same show 2 years ago and they were expecting speeds of up to 600Mb/s.
If the previews are pulled, and the Warner Brothers titles are still being pirated before they are even available to Canadians, then go look somewhere else. I pay to see movies I want to see. The odd time I will catch a free preview but that is a rarity. If the movie is of interest, I will pay to see it and don't care if there is a preview or not.
All this said, I really doubt that any correlation will be drawn from this.
I have to stop and think how things such as TV, Telephone, power, water and sewer are 'plumbed' into each suite. That would have to be an interesting problem to solve.
Just a matter of clarification on some of your points: DOCSIS is an ackronym for Data Over Cable Service Interface Specification, this has nothing specifically to do with voice or set-top boxes. There are two standards that deal with those PacketCable is the cablelabs standard for voice. OpenCable is the cablelabs standard for settop boxes.
There is no synchronized clock with regards to DOCSIS. PacketCable uses VoIP technology and, as the name implies, uses ip data packets for call transmission.
We are going to be installing eMTAs that have a 16 Hour battery backup for power outtages. Cable companies also backup their plant equipment with stand-by power supplies. The other point is that the trend in recent years is for people to make use of cordless phones more often than not. When the power is out, a cordless phone doesn't work regardless of who is carrying the call, unless of course you have alternate power for your phone, then see my first two points.
All this said, I don't know what your cable company does with regards to uptime, but there are options available to address all of the caveats. If they don't, they probably won't be very competative.
Typically, a well designed Digital Phone network will provide end to end QoS to protect calls from pops, clicks and whatever other impairments are associated with IP Data communications. Owning the network from the Customer to the PSTN Gateway (or even a completely protected IP Trunk) ensures full control over the call quality. Since the technology itself has a certain level of error survivability due to FEC in codecs, the call will not suffer from electrical interference typical with the worlds aging twisted pair networks. This provides a nice clear call, which isn't surprising. Providers such as Vonage have to play with many providers between their customers and PSTN gateways, most of which, they have no control over.
1. create a list of sites that they find are exploiting children 2. put together servers and software that can monitor ISP lines 3. provide servers and software to ISPs at no cost 4. ISPs only report on those that are going to those sites. 5. haul in the asses of those who are guilty of visiting said sites

Yes, I know there are a lot of those sites that are 'offshore' but I can assure you, it isn't from experience.
Having worked in the cable television industry for the past 15 or so years, I am going to have to highlight the fact that IPTV is far from a monopoly. Moreover, Verizon could hardly be called a monopoly, with emerging technologies such as VoIP, Cellular and Cable based Digital Phone service (yes it is just VoIP but is typically handled across a fully managed network) as well as other ISP options, they are set to face customer erosion in the near future.
I would think the buyer would have to charge the seller to ship the Canadian Tire Money (CTM) considering no one ever really has more than $0.25 notes. I know I usually walk away with $0.15 - $0.50 after any purchase, the bricks of CTMs would be enormous. Unless of course there is some online version of CTM that I am not seeing.
My apologies to those who, for obvious reasons, didn't appreciate my sense of humor, I should have put a bit more thought into it.
The thing about 'Everyone speaking english' was meant to be funny, and I suppose wasn't.
That said, it did raise a few interesting discussions. Most programs that I view do not have any SAP information, and rarely provide French programming.
This would be an excellent use of Second Audio Program (SAP) for TV shows. It would always be in sync, it wouldn't require anything to download/play, and most modern TVs support it any way. Everyone speaks english, so what is the big deal?
I have seen very very dark red algae blooms (red tide http://en.wikipedia.org/wiki/Red_tide) in waters off of the British Columbia Coast. I am guessing that this isn't something that is limited to just the pacific north west.
Considering this is only happening in one area over a short period of time, I am willing to guess that what is actually falling is an algae bloom. Suppose for a minute that a funnel cloud, or water spout had pulled water containing a deep red algae bloom into the atmosphere, and was suspended for some time until the water was brought down as percipitation.
I believe the prime time for algae blooms is in the summer, and correct me if I am wrong Monsoon season is also summer... isn't this a more plausible explanation?
We have heard of stories of small fish or frogs being dropped in rain fall, it would make sense that this could happen with smaller creatures.
There are solar systems that allow you to only 'buy' from the electric Co when your batteries are low. This isn't a bad option, but on the scale of a Datacenter, the sheer volume of the batteries required to convert the DC Solar to AC, and the accompanying conversion losses might not make it worthwhile.
Another option would be to get a natural gas line into the building, purchase your own generator, and when you aren't using the excess capacity of your generator, sell it back to the electric grid, if your utility provider would allow such a thing. I have no idea if that is any cheaper though.
oh one other thing. If you don't know how they calculate your peak, you aren't going to get very far as your results could differ from your bill. Make sure you are fully versed in the way they are quantifying your demand.
I am going to guess you have 3Phase power perhaps through more than one primary link. Do they charge based on the peak of one phase or the average of all. If you aren't balanced on your phase input into your building, you may be able to rebalance and see some benefit there. If you have one or two large UPS systems that are pulling equally across all three phases, make sure that the output of the UPS system is also balanced, that could end up bringing your input usage down.
This of course wouldn't help with your peak usage, but something to consider anyways.
Short of that, you would be looking for something that could store power and charge that at a regular rate. But then you could end up possibly shorting your demand on the output side based on the available power in that 'system' at peak times.
I am going to guess your best bet is to look at phase and load balancing through your power distribution network and make sure you have placed your clients. If I was in a similar situation, I would set up a collection of load coils across each hot lead in your power distribution network and graph the values on a tight schedule (in order to catch peaks) and determine what is responsible for your peaks.
Don't know if any of this would help, but it is discussion, mod accordingly.
I would agree that to some extent IPTV will play a role, as I said in my previous post. But cable systems are very efficient in broadcasting the same channel to a large number of people. IPTV my be more suitable for those channels that only have a handful of viewers or VoD. I like where IPTV is going, I am just not fully convinced that it is the endall solution for ALL channel delivery.

I kind of got the impression the whole building is rotating, perhaps that is just not the case. Wireless would be a pain in the ass if even feasible.

Does this mean Computer magazines are going to start having yearly swimsuit editions? This could be a good and a bad thing.
ah looked right at the last one... good to know i was paying attention to this post as much as I was paying attention in 12th grade physics.
Was your calculations based on 8mm or 8cm diameter center mass? I thought the article said 8cm.

I don't recall where I found the information previously that lead me to post about algae, but I believe there are some algae species that do not have DNA and are more RNA based... or something like that... I started working off of the following:
;)
Red Tide http://en.wikipedia.org/wiki/Red_tide
Red Algae http://en.wikipedia.org/wiki/Red_algae
Dinoflagellates http://en.wikipedia.org/wiki/Dinoflagellate
Any ways, seems much more plausible than ALIEN ATTACKERS FROM ALIEN WORLDS
