Part of the perceived problem is that the traditional mileage ratings don't apply to hybrids very well. Hybird drivers fleeing from the Hurricanes (on the ultra-congested roads) got much further away than the others, because their fuel supply was lasting 12-13 hours, IIRC
I can second the slow no go gas time. I put an inverter in mine. I used it last summer camping to run lights and a fridge by locking a key in the car and leaving it running. Over a 3 day campout I used less than a quarter tank of gas. If I was running from a storm, and stuck in traffic, I could go a long ways by ditching the AC.
EPA does not provide a listing of how much gas a car burns sitting at idle. This the the rate that that got people about 50 miles to a tank of gas leaving Houston. I wish the EPA sticker listed gallons/hour for all the driving done by not touching the gas, but pressing and releasing the brake. With the Prius, and the AC off, I believe it could go for days. Most other vehicles overheat and suck the tank dry in less than a half day.
If I had to flee a storm, I would much rather do it in a Prius.
That doesn't sound like anything that can't be "fixed" with a hex editor. Find out what on the card the data is looking for, serial munber? Find that info on the target card, change the line in the data to match that of target card.
This not a read write memory card. This is a computer on a card with some memory space. The computer program is not in read write memory. You simply will not be able to read the key (protected) and copy it to another card (unable to write to read only protected memory)
This is not your fathers compact flash memory drive card.
It is more like an H card for your dish network receiver.
or whatever, while preventing the "untrusted" device, if it has a compatible card reader and copies the protocols, from doing the same thing?
The untrusted device will not be able to convince the processor on the card it is a trusted device. The processor on the card then will not use the key to decrypt the file on the card for playback. The key is not stored in an area that can be read outside the card. The trusted device must handshake with the card. The data portion of the card contains the content in encrypted form. Copying off an encrypted file gets you an encrypted file. Writing the file to another card puts the file on a card with the wrong key to play the file. The key is not in read/write space.
Er, so if I copy a file from the memory card onto, say, an iPod, the memory card alters the way the iPod works? Huh? This makes no sense whatsoever.
Not quite. Your future I-pod will have a card slot just like your phone and computer. The card you bought from the music store will play in the slot. no card, no tunes. There is no copy to the I-pod. No card in the slot, no tunes. The card contains an encrypted file, a processor, and a hidden secure key. The file will be no key, no decrypt and play. The file copied to a second card, wrong key, no play. The DRM stops a copy of a copy of a copy. The encrypted file copies fine. The key and on card hash processor to make the file work is much harder to copy.
Copy a file to your I-pod and have it play is not an option. Plugging in the card and playing the card is an option.
You won't be buying from Sandisk. You will be buying from a customer of Sandisk. That customer will be selling songs on cards. The card will fit your phone, MP3 player, computer... But playing the file on the card without the original card (copy) won't work because the protected keys and processor are missing for the encrypted file.
When SanDisk starts manufacturing DRM-protected thumb drives and PNY or other manufacturers continue to sell unprotected thumb drives, I think the market will do the talking.
It won't be marketed as a recordable drive to end consumers. Read the article. It will be marketed as a pre-recorded CD/DVD that will fit in your phone, computer, MP3 player...
It is marketed as an itsy bitsy CD that can't be copied. If you use your computer and copy the encrypted file off the chip and record it as is onto another chip, the copy won't work because it requires the key and processor of the original chip. You won't be able to extract the key from one chip and copy it to another chip. You won't buy a album on a chip and make a copy for your friend. That is how this DRM works.
Presumably it requires the cooperation of "trusted" devices to restrict access to the unencrypted data, and untrusted devices won't have the decryption keys.
You buy your music already on a card. You collect cards much like collecting DVD's or CD's. The music file on the card is mated to the card's DRM key. Copying the encrypted file off the card and putting it on another card means the file won't play on the other card. Making a copy of a card to give to a friend to play on his phone simply won't work. You have to give him your original card which he then can play in his phone. While he has your card, you don't have the music. (unless it is permitted by the software such as the 5 copies given in the article example)
You have to have the file on the card and the original card it came on to play the file. The file placed on another card is designed to not work.
With the TrustedFlash chips, music studios can release albums or whole collections of musical groups on a single memory card that consumers could buy at stores and insert into their phones, MP3 players or laptops.
This is not a buy a blank and burn your own compilation. This is buy a pre-recorded and it is tied to the card. I'll play in your future cell phone, laptop, CF music player, but only from the original card. The file without the card does not work.
This is like old floppy games. Please insert the disk...
Making a custom compilation is not an option. Carying a case of cards with your phone is the new future of copyprotection. I'm voting with my wallet. It's a no vote.
Step 1) Copy once Step 2) Remove protection from your new copy Step 3) No more DRM.
The way I've seen it work for some digital marine charts is; 1) Copy once 2) Strange unrecognised binary file 3) copy to second device 4) works in original device but not in another device.
The chart is married to the card. Copying to a PC is OK. Copying back to the original card is OK. Copying to a second card is rejected by the boat nav. Original card only please.
You can use the chart in another boat, but only if it is on it's original card. This is hardware level DRM.
Notice almost any GPS you can buy that uses a map will only take a SD card? That is for in the future when you buy your boat or aircraft charts, they will come on a card and won't work if copied to another card. The chart and card are married and won't work without it's partner.
Charts for a local waterway won't be shared by a group of fishermen. Each will need to buy their own chart card. That's how the SD feature works.
Yes, although I thought SD memory had this kind of "feature" too, as did some of the enhanced memory sticks from sony.
That's the big reason I kept to regular CF cards whenever possible. Many salesmen brag how much faster a SD card is over a CF card. I've seen the talking points. I also bought a 40X CF card for my camera. (Minolta DiMAGE) Comparing new SD cards to the original CF speed isn't doing CF justice. A buffer in the camera makes up for the old slow card I have.

This is not a repacement fot the local video store. The Internet is a replacement for the local TV. The storms hit the Gulf states. I watched the video on the Internet, not the TV. The DRM and timeshifting problems with TIVO are moot on the Internet. I can catch the breaking news on the internet. If I missed the breaking news, I can still catch it on the Internet. TIVO has to play the DRM game, so why bother? A new TV to watch the limited junk on TV is not getting me to bother with a new TV. It just isn't worth it. A broadband connection is much better than a new digital TV and a TIVO.
I really wished the FCC would crack down on these ISPs and the lines that they own.
Have you seen your phone bill lately? The FCC won't do much until the subscribers start canceling service in large numbers.
The landline is just another way to pay taxes. Anybody rich enough to have a phone can pay taxes.

Pay vs. Happiness

· Score: 1
I'm 31. I can live stress-free on $10 per hour. But I like toys so I work harder. When I get close to feeling stressed, I cut back on work, which means cuts back on toys. But if you buy toys on credit, expect there to be no easy way to cut back on the stress that will likely follow.
I've noticed you can have a low paying high stress job, or you can have a much less stressful job for much better pay and benefits. It pays to have a good education. I quit my last job which was a 6 day a week, on call 24 X 7 for emergencies and took a 40 hour a week job with benefits and double the income. I do lots less customer service high stress stuff and have my weekends and evenings free for my family. A retirement plan, medical and dental are icing on the cake. If you don't like your high stress job, polish your resume and start looking.
I had a great hobby, now it's my full time job. Don't overlook jobs related to your hobby.
You can give your family soooo much more than a McMansion and two shiny cars in the driveway. Take them for a walk, teach your kids to throw the ball, play tennis, whatever... In time they'll come to appreciate it much more than sterilized existence in a suburban McHouse. I promise you, I guarantee you they'll appreciate the time with you much more than having marble countertops in the bathroom.
Very true. I have found some jobs are very demanding and pay very little. Other jobs that require the same hours pay twice as good. The increase in pay lets the wife become a full time mom. There is no longer a need for daycare and the problems of latch key kids. If you are willing to work long hours, make sure the benefit is worth it.
I doubled my pay and reduced my hours by quitting my last job and relocating over 3,000 miles. Working to pay for the house instead of renting has it's benefits after the house is paid for. Renting in retirement is the pits. Having lots of time to spoil the grandkids is priceless.
2 cars can be a requirement. It does buy time with the family. A 30 mile commute by car is 45 minutes. By bus/lightrail/bus, 2 hours. That's an extra 2-1/2 hours for the family. The wife can still take the kids to the ball game, do the shopping, and take the kids in for their dental and medical visits.
Working less hours because you do not want to pay for the second car is lost in the increased travel time. Also lost are full time health benefits. Our markets are not friendly for part time employees.

That would be one of the key factors to which HDTV to buy, for any geek, I would think.
Just remember, in the future, no DRM = no content. A non-DRM set will not play DRM content. Are you expecting non-DRM content in the future? It will be as mainstream as NON-Macrovision VHS tapes, NON-CSS DVDs, NON-Reigon coded DVDs, etc. Sure you can play your old VHS stuff you recorded off analog TV in the 1990's, but not in HDTV.
For new content and the new format, not geting something that can play DRM would be a waste of money unless you use your HDTV camcorder to produce all your own content.
Most of my content comes over the Internet, not from traditional TV sources.
I second that important question. (Set includes the required tuner, otherwise it's just a monitor)
Dorm dwellers, RV'er's, apartment renters, homes with kids (Dad has no interest in the purple dinosaur) and such. A one TV home theatre solution is not a solution for a house with a family. A multi thousand dollar set in each bedroom, kitchen, den, living room, etc are also not a solution.
Just where are the cheap small sets? Where is the over the air demo at the local electronics store? I keep looking. The demo is either for a subscription Satelite or Cable pay TV service, or from an in-store demo loop.
If it won't work in the store, how the heck do I expect it to work at home? Show me the sets in operation! Don't show me a 5.1 sound system, monitor, tuner package. I have a good stereo. I'm just looking for a few small inexpensive TV's to replace my analog stuff for the local news. Don't try to sell me components. I just want a TV for after analog does dark.
If the sets don't show up, then the Internet will be my TV of the future.
Is that possible? The chase for lower voltage -> less heat -> speed up the clock?
Yes. Many processors are limited by heat. Smaller transistors mean smaller connections means less capacatance and shorter connections. Less voltage most times means slower chips. Smaller low voltage parts means less power draw per transistor, faster transistors, and together they mean lower voltage and faster parts. Lower voltage does not make a faster part. Smaller parts using less power means faster parts for the same power in the same space. The overall result is lower voltage, faster part. Don't leave out the smaller parts portion of the triangle. Lowering the voltage alone does not make a faster part.
Perhaps a beam of infrared light would work better against this device.
I don't know much about this device, but many lights and other items emit large amounts of IR. To prevent the device from locking up on every stage light, task light, and reflections of light from every shiny surface in the room, I would suspect the device would modulate it's light source so it could detect reflections from it's light source and not all the IR reflections in the room. It may ignore a steady state IR source.
It's actualy easier, you just need a high powered IR source, such as a bunch of LED's,
the Cameras AGC automaticly adjusts so you turn totaly dark.
It depends on the camera. Some cameras use TTL metering from the CCD. This is after the IR filter. That screws up the AGC on cameras with an unfiltered detector for exposure. Many photographers know how to defeat that problem. Point the camera at another object nearby at about the same distance. Half press the shutter to lock the autofocus and exposure, reposition to the subject and finish taking the exposure. I use that often when the glare of a stage light or other bright source in view makes a mess of the exposure. IR exposure problems can be handled the same way.
That's okay, you can do it back. Just install this on your car to drive through red lights and avoid the photograph
Just how much are you willing to spend on in vehicle ECM? I don't have a spare video projector handy.
It's much easier, since they use a flash for traffic radar, to use slave strobes at your lisence plate. Their strobe trips your slave and adds lots of glare to the photo. Can you say police pursuit?
combined with a PC BIOS eraser or disk locking tool
I wish more PC's had a hardware jumper to prevent BIOS writes. A password provides only limited protection. My old PC has a EPROM, not an EEPROM. Only the BIOS settings can be changed, but not the BIOS routines. Newer machines can be wiped with a BIOS flash malware. A two position jumper would be great. A FLASH me position that provides an on screen warning, and a run position that disables flashing of the BIOS.
Locking of hard drives is another exploitable problem. I hope system manufactures add a challenge response routine to the hardware locking and BIOS flashing abilities. This should slow down an exploit due to the added variables.

Locking of hard drives is another exploitable problem. I hope system manufactures add a challenge response routine to the hardware locking and BIOS flashing abilities. This should slow down an exploit due to the added variables.
