I've done a few platter swaps and have had good luck if I can find the right donor drive. So far I've gotten data off most of the disks I've tried but sometimes the recovery rate can be as low as 25%.
I recommend that people buy drives in pairs. That way you have a good drive to use as parts once the data has been moved off to a newer drive. I do repairs in my house so there isn't a clean room in sight. If the board is fried, a board swap tends to do the trick but the bad sectors are stored on the board so the mapping will result in some bad data. I start with the hard drive in the freezer (using a external firewire case) trick first. That tends to get noisy bearings about 3 hours which is enough to copy data over. If that doesn't work, I do a platter swap. I disassemble the drive and I've found that normal printer paper works great for lifting out the platters with out scratching them. Just make sure you put them in the donor drive in the same order and don't flip them. Once the platters are in, it appears that the drives have a few days to live before they stop working. With head crashes, you might want to consider only putting the good platters in. I have yet to find a good cleaning solution so with crashes you have a very limited amount of time but head crashes seem to be rare these days.
Once you can read the disk, use DD to copy the data to a new disk. Don't try to mount it to look for a specific file unless you only need one file and mount it read only. For data file recovery, I use a mac program Data Rescue by Prosoft which is good except it sometimes is too good and pulls out the internals like pictures out of flash and office docs.
If your going to do this at home, take apart a few older disks first. Keep in mind they designed these things to be assembled quickly so there is a way to retract the heads completely off the platter so hunt around for it. There are some people who use vacuum cleaners to try to remove dust and others will use a shower to steam up a bathroom and wait until the steam clears with the hope of taking the dust away. I just open the drives on my computer desk.
1.14G? Maybe at liftoff. 7,648,000 lb of force on a 6,699,000 lb (and decreasing) object. Or after 150 seconds its 42 miles up and 73 nm downrange at 1st stage separation. Even Wikipedia claims 4G.
That is not all, however. Chips have reached a complexity of such that an infiltrator could modify the design in progress to implant backdoors, wiresniffing, and so on. That would take enormous skill...
Lets say you have the FPGA code for a FPGA for a firewall. All it takes is put a bit comparator to next to the input buffer (which could be hidden with the checksum hardware) and when the magic packet hits it, it sends a reset to the filter section causing it to default into a "pass all" mode. The real problem is finding the FPGA code but that could be trivial depending on who makes the chip.
If you keep repeating that, will it be true? My TV takes 3 Watts when off and 65 Watts when on and it uses that 3 W to keep the tube elements warm so I don't have to go out and buy another TV. There is a PC here beside my desk that also takes about 3 W so its going to use about $3.56 per year with the new higher rates compared with about $.024 per hour when its on. It uses that 3 watts to run in a suspended state so wake-on-lan works and it boot quickly. My cheap power meter (only reads it 1/2 w or.01A) also claims my DVD takes zero power when its off, as does laser printer, monitor and other devices. The cell phone chargers even less and the power supply for the mac lap top appears to go extended times with zero power consumption from the grid. My door bell uses more than the miscellaneous electronics I have in the house when they are "off". Out of the collection of things I've tested, biggest waster of power when it wasn't doing anything was a burned out CFL which was cranking up 100W ever since it burned out. I expect that worst things in my house as far as the grid is concerned is the CFL with power factors that can be as low as.20.
Back in the day when they first started charging for domains ($70 for 2 years), a major chunk of that went to fund research from the National Science Foundation however it was declared an "illegal tax".
Australia doesn't have this problem this week. They require that you have a registered business name or some other reason for having the domain name and as a result it has kept the com.au domain name space fairly clean how ever soon they will be changing the rules so they can make more money by allowing the criminals in.
How do you know how many domains someone has? My server is hosting about 75 domains but only a few of them are mine and those all appear to be registered to different groups yet I'm the tech contact for all the rest.
Remember when.eu was started up, there were people who set up several registrars who each had lots of companies claiming ownership to some domains and in the case of sex.eu there were about 200 different ones that improperly claimed a trademark so in the end it was given to a random one of the 20 people who where honest said "I want it but have no real claim".
Why are they using g-pon? The splitters now cost more than a road side fiber switch and the CPE also costs more than 100 FX equipment by a large margin. Sure you have to power the switches but you can get mixed copper/fiber for that and your not far from power lines anyway. A fully switch based network has the advantage that you can go from 100 mb to 10 gb on your existing network without any changes to the fiber.
SSN are not unique and sharing one with someone else is not a valid reason to get another one issued. Many fortune 500 companies ran into this when they started using them as unique keys. The SSA position on it is that thy try to make the numbers unique, and the ones issued lately are but in the past mistakes have been made and duplicate have been issued. They are unique combined with the first registered last name.
I think your argument comes down to "how many people are in the pool of experts". When Newton an Leibniz were doing their work, what % of scholars at the time had the drive and free time or need to research the direction they were headed? If the pool of "experts in the field" consisted of two people and they both came up with about the same thing, I would say that is obvious to someone in that field, no matter how small that field is.
If the patent hadn't been published and other people "invented" the same stuff, isn't clear that the invention is "obvious to someone practised in the arts"? or at least someone in the same field?
I run a web site that provides free hosting to bands that I think have a clue and my site has been banned by many universities because of the RIAA which has resulted in the bands not getting gigs in the US and other countries. From my point of view, the RIAA's actions are purely to prevent additional competition.
Power plugs tend to keep the same basic design but they have changed a great deal with the latest changes happening over the last few years. Now most countries require insulation sleeves around the pins and the 3rd ground pin is still not universal worldwide.
When it comes to the stuff that causes your tin foil hat to get warm, your way to late and they already took care of the rest years ago. For example why does every major Unix and router operating system use the encrypted root (or admin) password to seed the tcp sequence number. So if we look at what Solaris does with its tcp_strong_iss generator, its starts out by leaking bits that are derived from the password hash along with a very weak and predictable pseudo random number. The system is such that you have to watch the thing for a very long time but the entropy from the pseudo random generator goes away after a while and your left with just the bits of the hash which you can work backwards and collect enough of the encrypted password to get decent results in a random table. AIX, HPUX and IOS all do it about the same way.
I'm more worried that the Solaris coder that thought it would be a good idea to rewrite their telnetd in a way that opened a huge back door is still working for them.
There were no drug deals when the lights by my house were burned out but in the week following their replacement, there were several dealers hanging around and one girl who kept getting in cars with different guys. I'm guessing criminals need light too. One issue is that street lights keep peoples night vision from kicking in and its much batter for seeing motion than our color vision.
Where can you get an 8W CFL that produces as much light as a 100W bulb?
The mercury in a CFL is already hooked up with non-mercury atoms in complex molecules. Its is trivial to absorb that compared to having a drink out of a thermometer.
The mercury isn't liquid mercury like the stuff in thermometer. The stuff is bonded to the coating inside the bulb and that is light fluffy stuff that will not stay where its put.
Ikea takes them back but what do they do with them then? There isn't any place on this continent that can recycle them and its illegal to ship them away so I'm going with cynical theory that they don't recycle them.
I like the 2-3x number that keeps showing up. Many coal plants have mercury scrubbers over the next few years so how can that number be true? Also did you know the source of the mercury used in CFLs is from coal scrubbers? Why is it so importaint to get the mercury out of the coal smoke if it isn't a problem?
The number also assumes that your lights are are 5 times more efficient but I have not seen one that is more than about 1/2. Once you factor in power factor and energy costs to make the CFL, it doesn't save energy, it doesn't save CO2 and it doesn't save money. Remember that if a company in China pays an electrical bill, they will be paying about.004/kWh. You can calculate the minimum costs of making a CFL by starting with the glass. The 1st stage of melting glass is about 3 to 5 kWh per kg of glass with state of the art electric furnaces and most plants are far less efficient. The bending and sealing of the tubes will take somewhere between 20 and 100 times the energy. Recycling will take far more than 5 kWh per kg of glass assuming anyone wants to buy the leaded glass once its been recycled.
ITU would be great if you want to hand everything over to the local monopoly telco in your local country. It would mean that AT&T gets control of the US side of things, Telstra gets control of all parts AU, Deutsche Telekom get all things German and so on. There would be no room for smaller groups in the whole DNS (and IP assignment) arena. If you think the proposed solutions to end net neutrality are bad, they are just a tip of the iceberg that the ITU would push through.
The whole DNS vs Cuba thing just reenforces that.com is a US domain and there is nothing that can be done about that until US companies start to use.us which is never going to happen without lots of external pressure. I would be happy with its oversight going back to the National Science Foundation. Maybe they would end the nonsense about squatters.
Its more like they are using 10 channel repeaters and I don't know of anyone using more than 16 channel undersea repeaters which I expect is as large as its stocked on the repair ships. The 2 channel repeaters cost about US$1,000,000 each which gets expensive when you figure you need one every 100 to 200 km or so. I'm surprised that Google didn't look into the new technology from Alcatel which can go thousands of km without a repeater so you can keep all your repeating stations on dry land. Under sea cable its self is less than $10/m if you don't have chip in for the expensive under repeaters and the associated stuff to power them while keeping everything dry under extremely high pressures.
There are other cables from Australia -> US. Its just that companies like AT&T and Telstra don't talk about theirs. In fact the Southern Cross Cable was the modern cable to be hyped.
It doesn't matter what you don't know about either sociology nor canoe building. It turns out that when the 1st Europeans ran into the Polynesians they insisted in teaching them the new way to navigate which worked very well for local navigation but wasn't very good for long voyages but the older ways quickly seemed to have been forgotten and now the navigation of the ancient Polynesians trade routes is completely mystery to nearly everyone.
Maybe I need to research this. I need a good sail boat, a bit of cash, sat modem and some dive gear and I'll let you know how it goes in a few years....

No, 3 of them were the dodgy counterfeits. You still don't know about the 4th one since it could one of the properly made counterfeits.
It turns out that most laptop demos to major fortune 500 companies don't involve the laptop being on.
