External firewire/USB/Box on a cable has been the only way to get good recordings of analog inputs on a PC for years. As long as you do you A to D outside the box your fine.
OK first off MAC addresses are not seen outside your local segment unless a braindead protocal inserts them in the data portion of the packet. Corp envirnments can do QoS based upon mac they can even do vlan based upon mac but thats only because people dont have routers sitting in there cube to protect them from there corperate network in general. Your ISP cant and shouldent be able to look past your firewall and thats a good thing.
If it's a one off then it's a question of what you have at hand. If you have a 5k tape drive at each end and a pile of tapes that costs another grand use that. If you have a pile of DVD-RW's use that. This was in relation to moving data from a telescope I would hope they are moving data from every nights or at least most nights work.
I call BS, I can get a gigabit pipe in any major city for 10k a month. Assuming I just have two points I need to move data to thats 20k a month and I'm staying on the same backbone provider so I have contractual levverage is I cant get the throughput inside the one backbone. I can move 1TB is 8000+ seconds aka less than 3 hours. It takes nearly a day to get from LA to London as well with a ticket cost of what 2k on expedia booked a month out for an overnight trip. If you have to move a TB a day thats 60k in flights. FedEX is cheaper by far but so is provisioning a lamda on fiber and runnign your own routers. A hundred meagabit pipe is only a couple k for the two ends and moves a TB in a day about the same cost as the one plane ticket.
Tapes have there place and for this instance it might make sence not to dump the capital into running fiber out but I would think it would since a telescope isnt a short term project. Tapes are good at getting data to different endpoints since fedex goes just about everywhere. The other thing you have to consider is accademics writing papers generaly dont have a clue how to find a good price on bandwith most people dont, companies are still selling at the 200+ a meg pricepoint when they have competiors in the teens. Bandwith is an artificial market controled by telco's with a very low real costs.
Yes they allow new headers to the mail thats all fine and dandy (I would hate for spam assisin not to work) it's about allowing people to change things in DNS most importantly insert big ugly XML that needs to be retreived in a single packet or your overheard goes through the roof setting up a tcp session etc etc etc. Basicaly adding an extensible standard to something of a fixed size does not make sence. The packet simply can only be so big so you cant let anybody do whatever they want in it.
How about because XML is pretty bloated and an embrase and extend sort of language thats designed to let people insert new things without breaking old things. Meaning MS or anytbody else can introduce new tags that arent compatable with somebody elses tags, they shouldent collide but the bloat gets pretty bad when you have to support 2 3 4 20 differnet version of the same tags to be compabible with everybody. XML is good for programs that should be embraced and extended. Internet related thigns should come from RFC and be fixed one set of rules, at least I think so. One set of rules is what has gotten us email that works around the world in less than 20 years.
OK so pretty much you have just said either one is carbon neutral to the planet it's just a time scale issue. Saying that fosil fuels arent carbon neutral is a bit of a lie. It would be more correct to say that they have a long carbon cycle vs a short one. If people would look at the spin and lieing to mark it sound one way or the other we might be able to do something about it. I would like to know where they would put a pond that size and not have massive effects on the envirnemt. It would be a better question is can you grow the stuff in small batches and still have it be cost effective.
SSH might help if your hoping through some other box but VPN definatly does. 802.1x does a good job at some things it's actualy realy nice for puting people on the right vlan. But for WiFi I wouldent go with anything under a full VPN so all you get over the air is DHCP and VPN packets and you dont need DHCP packets that much.
Or your could live in the country where your property line is more than 100 yards from your front door and it's 5 miles to the nearest store and they have bread, milkd eggs and maybe some half and half. Oh yea you get to grow all the fresh food you want in the back yard and know it's fresh because you just picked it cant find that in any market, cows get a bit smeely but the milk sure tastes good same for the water from a well and not full extra chemicals to make it "better".
Still a single passanger car would be nice if it's didn't look like as much of a death trap. A car pool of discreat vehicals would be a nice idea it would get rid of the general issue of timing you could be late or work late without affecting others or being stranded.
It's a redesigned backend but they have redesigned the backend before most recently for the GSR's (the 12k line) I was implemeting them when they first shipped and while the front end is the same the bad end was rather different. This is nothing new for Cisco everything is pretty much C modules that get compiled for the new artitecture and/or written for the new hardware. It's realy not that hard to replace a software bit with hardware by just writting a wrapper module.
A side note read the specs for the OC768 Module it is clear channel only no sub interfaces this beast is realy only for interconnecting these things at 40gbps thats a lot of bandwith on one pipe.
Local loops will be affected in a large part by SBC, personaly I have DSL and cable just in case at my home and the cable shouldent be affected to badly, I think SBS owns some of the poles up here if they get damaged but I'm pretty sure the power company will take care of any repairs to the poles themselves. For the corprate type it's a big toss up a lot of the circuts for low end stuff are on SBC but most places with more than a handfull of DS3's general have fiber from multiple telco's installed.
OK as a router guy in the north east I deal with Verison and SBC on a regular basis sometimes at the same time. Verizon is good for calling a line installed when you cant even find the port or even better when you know they havent installed yet because you have the only key to the wiring closet and they havent show up yet. SBC is good for flipping circuts into loopback if they have been down for more than ten minutes and then insisting they arent looped back and everything looks good, course it magicaly starts working again afterwards you figure somebody looked and fixed it but they will never admit that this generaly happens a few hours after you call it in.
As for phone service no idea hope it's not as bad as data. There is allwasy VoIP:)
B5 was on at a regulary scedualed time it premiered at 1am monday into tuesday night on the local Fox station. No they didn't try and kill that never all the new shows run once a week a 1am. Friday night shouldent kill Enterprise the show will do that all by itself. And yes I think the theme song stinks my guess is they were to cheap to get a realy symphony to do real music.
I think the point is cosmetics in general are not a need. Getting dead or dismembered walking through a field rates pretty high on my list of things to avoid. A company does not need to make a new cosmetic people dont need a new cosmetic people do need all there limbs and there life. You can tell you have be to removed from reality and it's harshness when you start to value an animals life over your own species but that dosent mean we get to abuse them either. Use animals in war, sure go ahead if it means less lives lost or that some sergent comes back physcialy intact let the critters die. Making the cosmetic people come up with a different posibly more expensive method of testing isn't a great burden to avoid turturing animals, stem cell grown eyes would be a nice double good thing it would be something to test on for the cosmetic industry and might actualy do something usefull like give a blind person sight.

It's a tax difference not a cost of energy difference. Either way hopefully it will not lead to a conscious use of energy I've been in Europe and dislike the things they put up because there cost of energy is so high. Tiny little cars with no power for one. Even worse overall high prices of auto fuel up prices to everything else that needs to be shipped increasing cost of living and cost to produce goods. This effectivly raises the cost of doing anything in europe. We do need to look at energy use and find more CHEAPER sources and methods to get it. I'm no proponent of fossil fuels but like anything else in business you have to replace it with something a lot better not incrementaly so. personal aircraft that are nearly idiot proof and go faster than cars might do it.
Funny I do this all the time, besides hands on break and fix there isnt a whole lot of things you cant do remotly. It has a cost associated with it for the KVM switches the console over IP devices the Lights out cards etc. For Routers and Unix boxes it's easy enough to just use a serial term serv with a modem to get into anything you might need. Some of the better PC server MB's even have serial bios redirection allowing you to watch the device post.
Sys admin stuff might be harder to overshore but it's not imposible with some one time costs.
Ok first off you need more details how far apart the houses are is an important fact also how concerned about security are you? Does it all have to be centeralized from one point to many or can you rebranch from one home to others? Anyway assuming 30 homes relitivly close as in a city type setting with 1/2 acre lots or less and the ability to put gear out in the field here is what I would sugest.
Lots of PVC in the ground perferable angled to drain. Fiber is your best bet on the infrastructure side, it's wickedly expensive to terminate and the testing gear to do a real test is expensive. Put more fiber in then you plan on using just dont terminate it till you need it. Prep for the future and do everything over IP for the phones thats easy there are numerious VoIP PBX's and then just get a T1/E1 PRI (this may be different in the netherlands I think it's Euopean E1's there but PRI's should still be offered) thats nearly enough phone lines for every house to be making one call. Cisco 186 and 188's work well enough for a whole house but there are plently of other choices all about the same. Billing may be your issue there as without getting an overpriced software package your going to have to roll your own/get a secritary to do it for monthly billing.
IP is simple enough just flip from fiber to copper at the house those are less than 100 a unit for 100bt-100bfl. ATA188's have there own nat firewall sort of thing. With thirty houses you could do it on as little as a single public IP but ti would be nicer if you could grap a/24 from your carrier backup can allways be handled through NAT only for when the primary line is down. If your at all worried about speed setup a nice big web cache and force everybody through it via the router. Mail again is a decent box so it can spam and virus filter, make sure to back this box up regulary. Overall 100bfl is cheap gear in the used market for nice big switches, you can go 2km over easier to work with and cheaper multimode fiber as well.
Cable TV might be an issue simply because the boxes to flip that to and from IP are pretty commercial and if your talking about satalite dish I'm assuming a simulsat to get all the birds thats a very expensive proposition. For this it may well be worth running Coax just for simplicity's sake. If you home run everything with two peices of RG6 that would get you some room to manuver. I think quality will be a big issue here RF modulation done with anything but top grade gear looks horid and I have no idea what the status of HDTV in the Netherlands is either.
Radio well that should probably just get piped over the coax for the TV assuming you mean redistibution of local stations it's pretty simple kit just some amplifiers.
At the same time it's probably unclassified government information to get the raw data not that that is harder to fake just that it requires some colusion and coverup unlike a human just not noticing it. It's also a lot easier to get your own test done at the same time to reveal any scewed data.
My lord somebody else that thinks nuclear power is better than coal/oil/solar/gas on the large scale. A semi hauls about 40 tons btw. Now was that US needs or word needs?
I dont think you get it your talking about low end embedded raid controlers those are for the OS disks thats about it they are worthless in a datacenter, I'm talking datacenter here 50k plus square feet with millions in hardware it's what I know.
I dont sugest using raid drives for backup thats where tape fits in. (Optical if your needs are tiny and if your running more than one machine that dosent fit)
I'm talking about online real time block for block replication to a remote facility. If you have to use it its no better or worse than a crash and if your using windows your used to those. Moveover with OTM and similar techs I can make checkpoints that the OS and the applicatiosn assure me that everything is written out to disk and rollback to those same as any incremental backup just an oder of magnitude faster.
A disaster recovery plan has to take business needs into account if your thinking about ordering hardware in case of disaster then obviously it's not great business need to have it up and running. I design systems for when you need them up in minutes not days.
This whole thread is OT, I only chimed in for raid and backup. If he is just looking to duplicate CD's and time dosent matter buy a burner if it does stop using CD's or buy a robot.
I actualy build data centers as part of my living. I have not utilized an optical media for much anything other that inital setups and imaging, even that now has moved over to network for speed reasons. I also havent built a datacenter in 6 years that didn't need at least 3TB's of storage, and your not going to put that much storage on any optical media. If you have to restore that much data the same thing applies your looking at days even with current gear an online backup is one of the most effective ways to keep business continuity. And yes thank god I'm not a data center manager I just tell them what to do, if I had to deal with it day in and out I might just start telling people what I thaught.
I think you should look at the post he wanted to archive his CD collection RAID5 would work fine for that even striping for the simple reason it's not a backup as much as an archive, he isn't going to throw the CD's away. Now having said that for disaster recovery you should be looking at a combination of tape/disk and RAID generaly. You need a good long term backup with incrementals that can be easily provided by Tape and possibly optical media or cheap removable disk depending on the volume of data and how often it changes. For real disaster recovery nothing beats a live mirror to a SAN on the other side of the country with a local copy of your backup media. Now in particular to optical media I think it fits into few applications well at the corprate level as simply the cost per gig is pretty bad and the speed isn't great either. Optical still fits into some HSM applications because it's random access removable media or when you need to do restores of small file sets faster than a tape can fast forward.
Funny I just moved and got them. They had no problem with my Cisco UBR as a modem and I dont think it has many of those fun features least I dont see them in the IOS. Granted it took them 2 weeks to get the install correct 1 week for signal and another to stop sending me to this little private IP jail.
Even worse who realy wants to hire anybody with the taint of SCO on there resume? I'm not saying they didn't have some good people but lets face it managers do look at where your comming from and if your laid off from SCO that tell me that you were to dumb to leave let me correct that run while sending your resume to every head hunter you have ever known, away from that ship. Moral is start thinking about leaving when your company goes bad not when they lay you off as they tank.
Because per the SMTP RFC(working out of my head here in case anybody wants to find the URL) you are supposed to write the mail all the way out to disk before you accept it. That way even if the power failed at that instant you would have the mail sitting snug on the disk. The worst thing that should happen is a duplicate is sent.
