Ah but thats the stupid bit there are really two things a terrorist can do with an airplane blow it up or take it over. Blowing it up is impossible to stop since said terrorist can pack his rectum full of enough explosives and walk through security to take out the plane, he is suicidal at this point he could just blow up a suicide belt in security and take out as many if not more people than on a plane. Now the taking over bit 9/11 was done with jail house weapons again you will never stop a pointy piece of plastic and most of them can be made into weapons inside the security perimeter or on the plane. Now stopping them from gaining access to the controls is pretty effective.
What we currently have is security theater to make grandma think they are doing something. It's funny small private planes and charter jets have none of these rules you can still literally get a limo onto the tarmac and fly away the same thing at the far end as long as it's a domestic flight not much more for international.
Keeping drives around is pretty easy. Store files with added parity data to multiple hard drives at least 3 compare 2 hard drives at a clip a few times a year. Upgrade the drives every few years. Base cost about 400 for the best current best bang for your buck drives in 3 external enclosures. Tape generally works the same but the tape head cost needs to be amortized to save you money in the long run (500 GB HD about 100 bucks 400GB tape about 50 tape drive to use it 5k) The key is to differentiate backup from archive you archive things deemed important it's one of those librarian functions you backup everything in case things break. You need to figure out how to keep archives in perpetuity backups only need to be around for a few years.
Firewire can send the compressed data to the massive upscaller/decoder that can send the data to the TV. The TV can also send back remote codes to the decoder and storage medium. There does not have to be a one to one ratio on firewire you could have two TV's watching the same thing or something different think one set top box with DVR the can serve every TV in the house, adding a HTPC is trivial as connecting it to firewire. Pretty much it's designed to be the one digital cable moving all the video and audio around your home. Unfortunately they are not in the pocket of the mpaa so there is not all this mandatory encryption like HDMI/HDCP. Add that device classing is mandatory so you should never need drivers and things just work.
USB cheap no enforcement of mandatory classing so everything needs it's own driver. It's a dumb network so everybody can only talk to the controlling PC.
At that point though aren't you pretty much making it a thought crime? Real kids get hurt in kiddy porn. Some wac job spending all day making life like images from his imagination and sending it out to his sic friends is nasty but does not injure anybody. Maybe it's just me I do not like laws that make crimes without any obvious victims.
Maybe when we get some real leaders in politics we might get sensible laws but that requires people not be sheep because the sheep vote for whoever they think will stop the scary banging in the night from happening not do whats least bad for the most number of there current constituents / the citizens in general.
And it is impossible to do with a decent switch. Cisco and the like are more than capable of stopping this sort of attack. This is not to say that we should not continue down the path to encrypted sip.
I used something similar in school systems every time the machine booted it reverted to a fixed image, they could send that image from the network onto the PC's to upgrade them. Worked pretty well once you turned off USB/CDrom booting, locked the bios and locked the systems in place the kids couldn't defeat it easily. Teachers could just hit the reset button to boot to a clean OS.
They do big data centers use glycol, when it's cool outside the compressors turn off and they just run the fans. It's a bit more up front but has savings in areas where it gets below 45 on a regular basis. Another option is large blocks of ice with coolant running through them to shift power consumption to the night and reduce the amount of energy required (cheaper to make ice at night) but only for smaller facilities they leave a reserve capacity of x hours and/or go with n+1 setups.
Mass transit has the issue of taking more time than cars for most Americans. Were just getting some high speed trains in service and there prices are higher than flying the same distance (sub 300 mile). Until there is cheap faster than driving mass transit it's not viable, and since mass transit is never good (overcrowded, cell phone addicts etc) you need the first two. There is something depressing about watching highway traffic in rush hour go faster than the train or always faster than bus. Subways work for cities but some people dislike living in overcrowded expensive area's with high crime rates to save some money or time commuting. There were companies (IBM in the 80's) that were moving out into the burbs and trying to bring there staff with them by helping them buy homes in the same/surrounding towns.
Starbucks can claim the DMCA safe harbor for there wifi same as you can. Your ISP might shut you off when you try to claim it (it's against many but not all TOS for residential service) but you should be able to use it as a defense (IANAL). Now if you get this setup up correctly with real bandwidth you don't have either of the those issues as you are the abuse contact and that seems to set up up as an ISP from your average cop or mpaa goon. One side note make the whois point to a Canadian address to reduce the mpaa spam.
Having been involved with hosting I have to run though my favorite DMCA response.
We get a take down notice for some free hosting bits all we have is an email. We forward it and they respond with a funny/fake counter notice. Since it's the first time we get legal involved and they say forward it back and do not question it. We forward it to the original requester and keep the content up. They sued and got a summary judgment after 6 months we got the order from the court and removed it and hand over any records we had to who uploaded it.
Seems to be a good plan, They used tor to get to our site, they I would assume used tor to get to the free email service so we had no useful info. I would assume they did the same thing somewhere else and got the content back up. Overall the DMCA is not to bad in this from the ISP point of view, it should allow for a processing fee from the ISP paid by whoever makes the request, and ban ones on the responder (let the court get them to pay for it if they loose sure) since it's expensive to handle these things well.
Actually this could really speed up generating those tables, really RT's is a clever way of indexing the results of a brute force attack. It still takes piles of disk space to keep the tables around though I can fit a lot of them on cheap disk these days.
It would seem a lot of the logic behind the shuttle was to get the gear and the people there on one transport. While I personally think the shuttles design was most about getting the funding not building the most efficient/safe unit.
In any event it seems like the saturn v's could have gotten the IIS up in aprox 4 lifts, this would seem more efficient as there would be less hardware joining sections together.
Yup definite moral high ground there, always good to make sure that those pesky courts have nothing to do with DUI all those pesky rules and such.
Sure I'm not a fan of people that drink and drive. I'm not a fan of heavy handed punishment handed down by a cops with no injured parties either. All the cheer leading around this subject has led to bad laws and even worse enforcement. I take issue with any law that does not have any directly affected parties. Speeding on a highway, no issue speeding down a residential neighborhood and get a complaint well sounds like disturbing the peace to me. Funny thats an old law we did not seem to have to make a new one to fix the issue. Hit somebody while DUI sounds like at least reckless endangerment, assault with a deadly etc.
As a side note, I'm a sub 4 time a year drinker and generally at home or hotel or other venue where I can sleep it off. Why because I'm not a big fan of drinking and prefer to not have to worry about or submit to the police harassment of DUI checkpoints (can I see your papers please). I have been personally affected by drinking and driving (a friend killed a family of four while driving drunk we knew the family) so have seen each side of the situation. I leave in a city that chooses not to enforce DUI laws unless there is an injured party they have real criminals to deal with.

You can just wire them up but a cheap charging controller will keep the battery in shape longer. I did something similar with a 12 supply from ac mains to make an effective UPS for my cable modem, AP and voip adapter stack since I wanted phone when the power went out and the cheap UPS's did not have the runtime I was looking for. I have about 2 amps of draw and a 100amp hour battery so I'm good for a couple days.
Cramming lots of things onto one server running a single OS is generally problematic at best, it's the classic small IT shop mistake for long term reliability. Vmware can alleviate that by dedicating an OS to a function so you can do things like reboots without affecting a small pile of ancillary systems add a san and now your not adding piles of disks with each new server and can do vm level load balancing and clustering, have to replace some hardware move all the vm's off without any outage and fix the gear move them back when it's tested good. Windows servers are generally not good at running multiple anything, a unix can use it's better shared library system and chroot environments to run anything that can run under than kernel next to each other but VM's can do more and be easier to setup while consuming only a little more resources.
Having gone through a few PCI audits what they accept for logging is pretty simple, log to local + remote don't let anybody on the remote with rights to delete or change the copies, use selinux or similar to alert on change and backup regularly and ship the tapes off site. For me this general means the daily or weekly off site tape rotation gets a new class of tapes with 7+ year retention holding the logs generally sever copies of the same log since it's a 90 day local retention on the central server and tape is cheap. This means even if I have to pull back a tape I have a nice paper trail as to who touched it and when locally along with an uninterested vendor's log to the same. If we need to get them reviewed by a third party we can get them the next tape from the off site vendor shipped directly to them. This passes the auditors and legal, PCI is pretty weak compared to SOX or Hippa really it's just a way to push blame to the merchant since PCI is written to be vague and open to interpretation.
Ethernet is useful because it's cheap, I can attach a 10bt host to a switch and have it transmit the same frame over 100kbt with very little work. I have clients that love Ethernet it's orders of magnitude cheaper than it's main alternative Packet over Sonet. So pretty much it's good enough for most and cheap. In the PC server world the marketing guys want to say they have the latest and greatest copper Ethernet built in and supporting every old standard back to 10bt. This means they ask there chip suppliers to build it and make it cheap. Scale and cutting every corner possible drive down the costs so that it's a couple bucks to add multiple ports of 1000bt today and 10kbt is getting cheaper and cheaper.
I doubt it the cable card people nurfed pretty much all the useful features. I'm sticking with my series 2 SD and HD tivo's at least I can move content back and forth and between them. Having a weeks worth of general hospital automatically sync to the ipod has a big WAF potential.
Network speeds 40gb a sec aprox 4GB a sec notice the case it makes a difference. Networks are bits hard drives etc are bytes. Either way it's an impressive speed.
Well of course she has a quad proc opteron. Actually 4GB a sec is not that hard to find to primary ram pci-e is capable of those speeds. Now you do need a serious raid array to deal with that about 50 spindles in raid 0 to deal with it.
I can tipple the transfer rate and reduce the average seek time by about the same by using 3 sets of heads. Oh you wanted something thats cost effective please move along. Really though I do not know why they could not use multiple servo motors to at least split the heads already on server class drives, any hardware geeks want to chime in? It seems there is a big push for 2.5 inch SAS drives I cant see why you could not stack some of those platters in a 3.5 and add extra heads and controlling gear? Sure your not speeding up single transfers but your cutting the rotational latency in half and allowing multiple operations at once great for servers.
The funny thing is I have a client that pulls 10mbs all day every day getting tickets out of ticket master and the like and then auctioning them off. I talked to him once and he uses a mix of computer and human analysis to defeat them. Capcha's do not work when you can pay somebody a few cents to do the work to buy a tens to hundreds of dollars in tickets.
