Home small scale generation is ineffecient. If you don't believe me, try it sometime. The demand swings for a typical house with electric heat, water heater, cooking, air condidtioning, laundry, etc are so big, a typical home would need at least a 20KW plant even though most evenings watching the late show only need less than 2KW. To get by with a smaller plant, you would need to provide your own rolling blackouts. EG heat and water heater would shut off when the stove is used etc. Many off griders have to curtail the peak consumption a lot to get by with a reasonable size electric plant. This means; no electric water heater, electric heat, electric stove, air conditioning, security lighting, etc. Everything except TV, Radio, Lights. fridge, and such are non electric. Chip manufacture uses lots of power and it needs to be cheap. Otherwise other manufactures with lower cost will take the market. Quadrupling or more the cost of power for on site generation is not an option.
Have you seen the number of new FABS Intel has built in the last 5 years? Sure an existing fab can't grow and use more power, but when chip demand is high, the production ramps up and new fabs are built. New Mexico, Oregon, Colorado and other places all have new fabs. I know of only one fab that was shut down due to age.
Most FAB's DO have backup power. The servers are on UPS's. Factory PC's are on UPS's. Office PC's are not. All recent stuff has been saved to a server, so only the latest e-mail or doc revision might not get saved, but it is easly recreated when the lights come back on. Many of the manufacturing tools will shut down in an outage. The backup power is not large enough to handle all the chillers and such the tools need so fabs will go into an organized shutdown. Many tools have a local UPS and will finish the current job so nothing gets stuck in the oven so to speak, then will not start any new jobs before tempratures etc. go out of tolorance. This prevents wafer loss everytime there is a power glitch. However due to the nature of required air handlers to maintain a cleanroom environment, backup power is a requirement to support a FAB. Otherwise DECON after an outage takes too much time and damages too much product. I don't know if this is true for all chip manufactures but it is where I work.
I wonder if it will be very temprature sensitive and require a X-Y current curve run on it once in a while to calibrate the read currents like the good ole days of core memory?
Think about it. Go the other way from 32 bits back to 16.. That's a 286. How about back to 8 bits? An IBM XT with a max address space of 1 meg. 640K memory after you reserve some of the address space for I/O. You know useless stuff like video, serial ports, floppy and hard drive controllers and such. Would you ever go back? I thought not. Now a chance to make the step from 32 bit to 64? Shouldn't even be a question.
Anybody notice the Netscape e-mail client already does this? I open it and it puts a new ad before it fetches the mail. The nice thing is it also adds value by also giving a news headline with it. Does Opera provide any information or just advertisements to ignore?
Change locks/passwords/combinations/passphrases often
Destroy old records and old passwords. This weeks captured key should not open last weeks mail. A place I used to work sent keys in the public mail. If it arrived OK it was used the next week. It was mailed from random locations to random trusted employees. If it showed signs of tampering or did not arrive, it was rejected an not used. Enough said.
What will your defense be when your captured keystroke password opens the previously captured encrypted file? They were specificaly looking for a password to a file they already captured.
And what is your keyboard going to output on the connector that has the recording box?(firmware) Later, they just push "play" and the computer does not know there is no care in the keyboard slot. They have a record of the whole thing. I would not use an external attached reader except in a location where the computer had physical security and limited access for any secure stuff.
I prefer "warrenty void if removed stickers". Not the generic kind, but ones that tear apart and have a computer shop name on them. They can not be replaced by a generic as it would not be the same. One over a screw hole does the trick.
I noticed in the FBI request, they asked for a time extension as the target computer was not at the target location. It had been moved. This prevented them from installing the password capturing stuff. Physical security is important folks! If they can't touch it, they can't hack it!
4 Hidden datalogger on phone line and alarm sensors. Outgoing call from alarm (before reset) can be logged. A furnace "energy usage" meter is a good cover for a datalogger. The alarm company does not know your PIN after you change it. The alarm should trip before they can enter service mode. Wireless sensor in desk trips "other" silent local alarm and datalogger. Datalogger should display "number of cycles" and "time of last cycle". This will alert you if you were visisted since you left for work in the morning. Check and set both alarms everytime you go out and check the datalogger everytime you return. Monitoring companies are useless in the visited by FBI department.

Do a search on code hopping devices. Most new alarms and door openers use it to stop this type of hack. Each time a remote button is pushed, it uses a new code. Used code is rejected. This prevents captured code from working later. The receiver follows the code sequence of the remote. It uses lots more than 1024 combinations. This makes sequential scanning take a long time and sequential codes are rejected. No dip switches are used. The receiver has to learn the remote by entering a program mode on the receiver and reading the remotes current count. Remotes have both a fixed serial number and changing code. They are hashed together. This provides security and the ablility of the receiver to learn and track several remotes. It also prevents an off the shelf hacked remote from finding the right combo. It will always have the wrong serial number. Most remotes of the code hopping type have enough unique combinations to never repeat a sequence in a lifetime of normal use. Digital security has come to car alarms and garage door openers. There is still some older openers out there. Car alarms generaly are not very old and use the more secure stuff. Hacking the panic mode is just about impossible. Most openers can easly have the receiver replaced as an external item. This is an easy way to secure your garage. The old receiver makes a great remote for a wireless doorbell. (I did mine myself)
How long before you could get connected back into fidonet mail? I haven't had a standalone BBS up for about 8 years now. I have no idea how long it would take to get it back into a net and get users again.
I keep hearing about how wonderful online voting will be and more accurate than the Florida election. I can see a DOS ruining an election. Keep that in mind when your politicians want to use online voting. How do you recount 3/4 of the nation could not connect!
I know what you mean. I also have a 10 inch Reel to Reel. It still works great. It was much better than the early cassettes. However with the advent of chrome tape, the fidelity improved a lot on cassettes. Remember when the Laserdisk was promised to be cheaper than videotape? I have a $1000 player and fewer than 15 movies. I'll never buy any new format until the chicken and egg game shows it a very established, usable and inexpensive format. (like MP3's and CD's are now.)
Somehow I see the cripled format limited to a very niche market just like the DAT cassette and the Minidisc. Do to the limits on use, it will never get past the chicken and egg syndrome. Un-sold CD's due to a lack of players in the market will reduce the amount of releases in that format.
12 inch Laserdisks were encumbered by high price. The promise was made they would be cheaper than videocassettes. Studios were afraid of a format that would last forever and either made the license very high for the format or refused to release in that format. The result was few good films at high prices or cheap stuff like "How to watch NFL Football" In 10 years I have collected less than 15 movies for my $1000 player.
I see the new CD audio format rejected by price and lack of titles + the added burden of the elimination of fair use. Only a few geeky audiofiles will buy them. It will be bought by the same people who buy the KIMBERKABLE silver speaker wire at jewlery prices. It won't appeal to the Monster Wire and below crowd. I predict the format will be stillborn.
This of course only happens where a resonant length of metal creates a high standing wave. An antenna with a load will drop the Q of the circuit and reduce the peak resonant voltage. I plan on having a reciever connected to the antenna on the car. Try the cultry experiment with and without a cup of coffee. Notice the difference?
Get a clue. My 800 watt microwave oven runs on 2.4 Ghz and doesn't break down the air. How many watts are you planning on receiving on your antenna. I don't plan to receive anything stronger than 1 millionth of what my home microwave oven produces. I would be suprised if my antenna received anything over a few microvolts.
Most people do not want a 36 inch radome ball on their car. It would hold the gyro stable platform to use the dish on the car. Even though it is common on larger boats and ships at sea, I have never seen a gyro steered dish on a car. It is also a high maitnance item. The Gyro compass used to orient the dish isn't cheap.
Of course it runs Windows. They want to sell to 90% of the population, not 10%. It will be a while before the general population is ready to deal with the Logon prompt of our favorite OS. They want instant on use. There is little concern for security (untill after it's stolen). Other OS'es have a learning curve for most people. Palm for a long time only sold well by word of mouth. Someone showed someone else how easy it is to use without a keyboard. Most people are too afraid to spend a few hundred bucks to see if the UI will work properly without being shown first. Showing a product that you can take on the airplane that isn't too heavy and works just like your desktop is a selling point for most people.
It almost died and got replaced entirely by CDR and CDRW. CD players became the universal music/data format the minidisk should have been. The added cost of the player for the SDMI made larger bulkier CD walkmans the norm instead until the RIO MP3 player replaced it. Blank CDR's are easy to find and you don't need a seprate recorder to record both audio and or data. Minidisc players have been replaced my MP3 players in the portable personal music market. This is a market the Minidisk could have had for years! Instead it became a niche market item with very limited use due to the high cost. Most minidisc players I have seen on display lately have been marked "closeout". Jaz and ZIP drives could have been replaced by Minidisc drives if they were open to BINARY and MUSIC formats. This could have made them cheaper and more popular and could have been the standard. The loss of the ability of recording anything to take jogging excluded this player from this market. CDR and CDRW are now the standard for computer backups and ripping CD tracks for use in your car. I don't leave my $15 - $26 original CD's in my car. As the sign at the lot says, don't leave your valuables in your car. The Home Recording Act permits copying a CD to cassette/MP3/CD to use in my car or in my walkman to protect the original. (a backup by all definitions) The restrictive nature of the MD player excludes it for this use. Home backups are the only way to prevent loss due to overheating in the sun or theft. Most record stores will laugh if I say I want to exchange my "Dark Side of the Moon" CD because I left it in the sun and it warped. A fifty cent blank CDR is a cheap insurance on the original "Mobile Fidelity Labs" original.

Change keys often! Emulate a code hopping device. Anything new captured would be useless on an old file they already have.
wow! That is not good. Even your boot up root password is not safe from this. Dual boot isn't safe.
