This has been "going to happen" since, at least, the 1940s. At least once a decade someone reinvents the idea and creates a lot of interest. Then it dies again for a while.
The entire power grid is an RF choke. RF over the power lines works until it gets to a transformer. That's a good thing because it reduces impulse noise which can play havoc with electronic equipment. Fast rise time impulse noise on power lines is a problem in electronic equipment and instrumentation.
That's what the Tempest standard is for. It dates from the late 70s/early 80s when they banned all removable anything. The guy they busted was an intelligence analyst. That might explain his access. If the information was secret or higher then it shouldn't be available to someone working alone on an office desktop. The entire incident doesn't make much sense.
Everything I've seen from that leak has been been in the media before. No where is the classification level mentioned.
Wall St firms have better security than this. All access to sensitive information is logged, and passed on to security. If the access isn't legitimate then you're out the door at minimum.
I find this whole argument ridiculous. Isn't the simple, effective solution to simply charge customers based on the amount of data they consume?
Yes, that makes sense. Or you can get a dedicated connection. A T1 (1.5 Mbs) is about $450.00 a month. Or you can get a T3 (43.2 Mbs) for $4,000.00/month or more.
I have a broadband connection that gives me 26.03 Mbs down and 5.23 Mbs up (at 10:00 am). It's a shared resource. The speed varies depending on the total load on the distribtuion node. For the difference in cost it's worth it. Most of the time I get better then T1 speed for one tenth of the cost.
The power going to your house is AC. Batteries are DC. In order to charge a battery you have to convert AC to DC. You do that with a rectifier normally or an AC motor/DC generator set. The problem with fast charging is the current (Amps) required.
The quantity of energy is KWH (Killo Watt Hours). If the battery stores 30KWH then it would take 30KW (the rate) for 1 hour to charge the battery.
For a discharged 48 Volt battery the charging current for one hour would be;
I = 30 KW (charging rate) / 48 (charging voltage) = 625 Amps. If you cut the time to 6 minutes then the current would be 10 times that (6,250 Amps). I wouldn't want to be anywhere near that operation.
The ampacity of wire depends on it's cross sectional area. A current of 625 Amps is close to the spec for 2000 MCM (depending on temperature rating), which is 1.92 inches (48.8 mm) in diameter, so it would require buss bars. The fast charge rate (6 minutes) would require over 10 times that conductor cross section area. Conductors that big are not manageable by hand and currents that high are very dangerous.
So physics says the if you want to charge a car to go 375 miles and the car has the same drag as a honda then it takes 1.8 megawatts if you want to charge it in 6 minutes. that's the minimum. bad batteries and motors require more.
Your numbers look right. The charging current at 240 Volts would be 7,500 amps. 0000 AGW copper is only good for 380 Amps. It would require buss bars.
I hope they pay the price for their ignorance and hubris. What did they get for buying Sun, exactly?
They got hardware which is what they've wanted for a long time. Sun has a wide range of great hardware and a very solid OS. The evolution of Oracle DB requires intimate control of the system at the hardware level. The database server will be able to directly control resource allocation.
I don't think they were interested in the rest of the company. It's probably just in the way. It appears they are focusing on their area of expertise.
The word, I think, is "turbine" (or even "jet turbine,")-- not "Jet powered".
How noisy were they?
Not noisy at all. One of my customers brought one into the shop so we could check it out. It was quieter then most cars. It just sounded different. The mileage was better then most cars of that time.
I rode in it. It was very quiet inside and had excellent acceleration. A really nice car. It's too bad they never put them in production.
I'd like to monitor the entire house. I've thought about the whole shebang... monitoring every circuit - but that would be more complex and expensive.
Black and Decker has a unit that mounts on the meter head and gets info from the rotating disk. There is no wiring involved. The remote unit recieves the signal and displays power usage, etc. On the web it's around $70.00.
I still don't get it - why cars need so much software? Older cars worked quite well with just mechanical controls, so why there are so many computers in new cars?
Electronic controls are cheaper and they can be installed faster. Thats a big reduction in manufacturing cost. They make routine diagnostics easier and they are easy to modify.
Reliability is questionable. A car is a bad environment for digital controls due to the large amount of electrical noise, common mode noise, power supply internal impedance, poor grounding, extreme temperatures, etc.
I don't trust them on critical systems that can casue loss of control.
If you need a cell phone you should stick to developed and marked trails. That's a good way to get experience and test your equipment and methods. Blistered feet can disable you for days. Keep the weight down. Don't carry anything you don't need.
For wilderness areas you need survival training and experience. It's best to use the buddy system. Check in with the ranger station where you will get any necessary permits and information on local conditions. Tell them where you are going and when you'll return. It's like filing a flight plan.
Interesting. Do they then "certify" the software? Is there a designation for this?
I only heard it referred to as "approval". No one talked about it because they didn't want to jinx the project. When the approval comes through everyone gets a slap on the back and a lot of free beer.
That's only one part of a product. When all other aspects are approved then the complete product can be tested. If it does what is claimed and that has medical value, then the product gets approved and moves on to testing in the field. It takes a long time to get something to the point where it's a marketable product.
The FDA requirements on software are strict. There are requirements for coding practices, testing, QA, etc. Inspectors show up, without notice, to check for compliance. The code reviews are very thorough and require a manager and at least two other programmers. All code has to be instrumented and scripts written to force execution of all code. The output traces from instrumentation have to be fully documented. Everything that happens is documented.
They require the source code with all changes documented, test scripts, fully documented code intstrumentation output, full QA test documentation, etc. All these things must be signed by the programmer, reviewers and managers.
All this goes to the FDA along with a system for testing. They review the code, test the system and call with questions. The FDA is interested in suggestions on improvements to the process.
That process adds a lot to the development time and cost for a project. It can't guarantee perfection but they take a very good shot at it.
How about bringing the fabs back to the U.S.? Too many chip manufacturers have gone overseas.
The fabs moved overseas because of EPA regulations. That's the same reason a lot of manufacturing is now done off-shore. The cost of dealing with regulations is a bigger factor then labor.
Why not blame real issues, like parents being less involved in children's lives (daycare, TV babysitting, games babysitting) in terms of a personal touch....
I think the disintegration of the extended family and stable neighborhoods is a big contributor.
When I grew up (1945- ), my dad was a truck driver. My mom stayed home. My grandmother and uncle lived in the same building. There was always a family member to watch us. The neighborhood was like an extension of the family. Everyone was willing to teach us what they knew. We were encouraged to tackle the impossible.
Most of us had Erector sets before by the age of 6. Chemistry sets were later. Nothing was thrown away. If something broke the kids were expected to try to fix it. There was the library if we needed to learn how. If we really got stuck an adult would help us.
When I wanted a short wave radio, my dad asked me for a list of parts. I gave him the list and he took me with him to buy the stuff I needed. "I don't know how" was not an excuse. By the time I started high school I had an o-scope and a work shop in the basement. When we needed something, someone in the neighborhood usually could help us.
We always had adults around that we knew well and could count on. There were no day care centers and no one I knew ever stayed with a baby sitter. We were raised by the cooperation of everyone, including teachers.
For the record we lived near one of the tire factories where a lot of the neighbors were employed. It was a normal neighborhood with a lot of veterans refugees from WW-II.
We were also safe. If someone yelled for help, help would come from every direction.
Being creative is easy in an environment like that.

From an article on www.thecarconnection.com
The battery capacity is 53 KWH
The charge rate for 4 hours would be 12.25 KW. so the current would be 55 Amps at 240 Volts.
The charge rate for 8 hours would be 6.75 KW so the current would be 27.6 Amps at 240 Volts.
That does not include any inefficiency in the charger.
The motor is 185 KW (248 hp). The article doesn't give the weight.
You sure it was watts and not wat/hours?
Watts = Volts x Amps.
Amps = Watts / Volts.
If it's watts then:it would be 70 amps at 240 volts. I wouldn't charge a battery at that level.
Look at their customer list at www.atg.com Fortune 10 and Fortune 500.
Oracle will be able to supply enterprise solutions from the power connection to the end user. No finger pointing. Just like IBM did in the 60s.

Much of '60s activism was powered by music. That's over. Today's musicians have near zero political effect.

There is no excuse for critical anything to be on the Internet. This is what happens when people are put in charge of something they don't understand.
Inventing an answer for an imaginary problem is not big thing. Implementing it is a different story.

It's firmware, meaning software in a ROM. It's only slightly unconventional.
This problem goes back to the first ROMs ever used. ROMs should always be verified. That's basic QC procedure.
The FA doesn't have any real information. Most likely a beta version got into the manufacturing stream. The problem is just sloppy QA.

Good subjects for a Hasselblad.

I didn't see any proof that the scam exists, other then anecdotes.
Other than the original phone call, what they describe sounds like Microsoft tech support.
Perhaps the scam is a scam.
ICANN is in the business of hyping domain name sales and cashing in on it. Look at their TLD selloff.
Spot on.
It's just another way to sell air.
