The exodus has started from Yahoo Groups. They have not made their horrible interface worse in the past couple of weeks however there is every expectation that they will be discontinued or destroyed shortly.
I wonder what will happen to the email services they provide to ISPs like AT&T which already work poorly or not at all.
I'm all for strong encryption and absolutely against government-mandated backdoors, but I think in principle this is actually okay. This is the appropriate flip-side of having strong encryption that the government can't break. If, with probable cause, they subpoena you for access to the existing content, you should provide it.
The problem with this is the same as when the government pinky swears that it will not seize and search every bit of data traversing the internet with or without a warrant or due process; there is no way to hold them to it short of strong encryption which creates an arms race that they will lose and not only do they lose the ability to inspect data without a warrant, they also lose the ability to inspect encrypted data even with one. One of the papers which came out of the NSA said this very thing; once they get caught siphoning up domestic data, the increased use of encryption in response is going to make it more difficult for all law enforcement. Well, that happened.
Deniable encryption can be used. Now what does the court do? And if that is not sufficient, there are way to store an encryption key or password such that it cannot be seized without destruction or at least making it likely that it is no longer available. For instance store the password in the ordering of a deck of cards.
The only solutions to these problems are statutory which just brings the issue out into the open where they do not want it. It was a much better situation for them when everybody thought their communications were secure when really they were not.
Except that you don't have to comply with opening your own safe if you're a suspect; if you don't, the police will just hire someone to crack the safe.
And it is not like it is impossible to crack any symmetrical or asymmetrical encryption using brute force. It will only take at most the same amount of time that a copyright of "limited" time can exist thanks to the Supreme Court's ruling on that subject.
When I worked election security for a couple years in southern California, they did not even *count* the third party votes. Precinct workers would take some ballot boxes home at night before delivering them to be counted. Is that the kind of public service third parties can avail themselves of?
Neighboring Orange County gets their water from wells instead of the California Aqueduct like Los Angeles so instead of paving their rivers and flood control channels, they leave them open and where practical bulldoze earthen mazes along the bottoms of the channels so the water takes longer to reach the ocean. Los Angeles has no need to conserve water like this since they get their water from the California Aqueduct and have the political power to continue to do so.
Napoleon: I want trees planted along the sides of the roads so my soldiers can march in the shade. Minister: But sir, the trees will take years to grow? Napoleon: Yes, so start immediately.
Implement the grid-tie as a portable system which plugs in instead of a fixed installation.
I know of a case in Los Angeles County where they were building a mountain top transmitting location and when they went to install the transmitters, the county told them they needed separate permits for each fixed installation and that it would take months to process the paperwork. So the solution was to put all of the equipment racks on rollers and add extension cords and outlets so they could be plugged in for power. The county got exactly what they wanted; when the next earthquake hit, the racks rolled around pulling the cords out of the power sockets resulting in loss of their communication systems. But at least it was all legal.
I doubt this kind of protection for rechargeable lithium cells will become common. It increases the cost and takes up space which would otherwise go toward greater capacity so the cells will be more expensive and have less capacity.
When consumers look at their options, are they going to buy the more expensive cell which has less capacity but is "protected"?
The power MOSFETs are back to back in series so they can disconnect the battery if over charged or over discharged. So I assume the SOT-23-6 implements a window comparator and is something like this:
That is nice that they implemented a low voltage disconnect inside the cells instead of just a fuse; I assume it involves a MOSFET, low power comparator, and reference but I wonder if they managed something even simpler.
The destructive failures seem to crop up in powerful flashlights when users install either mismatched cells or cells with different charge conditions; the cell with the lowest capacity discharges first and the eventual reverse discharge causes self destructive thermal runaway.
As far as identifying cells for a charger, I would use two black and white bands and a pair of photosensors in the charger but getting everybody to agree on a standard? No way. I actually did this once on a custom charger using electrical tape.
The digital audio itself should be a major improvement over analog assuming lossy compression is not overused however taking advantage of it requires a good microphone and speaker on both sides. The old analog handsets were pretty good for this but current hardware has poor performance if only because of its form factor.
If you're inside a simulation, then you can't run any tests to find out, now can you?
Sure you can. But every time we find an exploit, the operators halt the simulation, patch the microcode, and restore the state from a previous checkpoint.
But in this case we are talking about standardized rechargeable lithium cells and not entire batteries. Adding protection circuitry to individual cells beyond a fuse or thermal breaker will be expensive, difficult, and of marginal effectiveness. Using a chemistry like LiFePO4 would make the cells much safer but the charger still has to be able to distinguish its lower charging voltage somehow and marketing is going to play it up as the lower capacity budget cell.
There are 2 problems with standard sized lithium rechargeable batteries:
1. There are at least 3 different chemistries and just those 3 have 2 significantly different charging voltages. There is no way for the charger to know which is which so the user has to set it manually. This by itself may not present a hazard however charging the batteries incorrectly can damage them.
2. During discharge, if one cell in a string has lower capacity, then it can either fall below its minimum discharge voltage or even reverse. This by itself has been known to cause hazardous fires.
NiCd and NiMH cells suffer from neither of these problems although a charger designed for NiCd cells may damage NiMH cells. At worst they just leak potassium hydroxide.
Poor quality mains power is not really an excuse but designing the ballast to handle high voltage surges would add to the cost slightly. The short lifetime that electronic ballasts have in both LED and compact fluorescent lighting is do to the lack of derating and the use of aluminum electrolytic capacitors in the ballasts.
Incandescent bulbs have a brightness which is proportional to the 3.5th power of the voltage, a lifetime which is inversely proportional to the 16th (!) power of the voltage, and an efficiency which is proportional to the 0.5 power of the voltage. So raising the efficiency has a massive cost in terms of the operating life. As a practical matter, standard 1000 hour bulbs used several times their cost in electricity so long life bulbs were only used where access was difficult.

But still a "limited time" as defined by the Supreme Court.
This is only the case because prosecutors choose not to enforce them.

You're kidding, right?
Nothing will ever exonerate him even though he has not even been charged yet.
Generate and store your encryption key using the serial numbers from a set of ordered bills. It is not your fault that the police stole the 100s.
Alternatively use a multi-volume set of books. What do you mean volume 6 is missing?

They are already doing nothing and instead creating a job program for politicians, lawyers, and their lackeys.
Until your ISP caps your IP traffic so you can only access a fraction of that 1 TB per month.
Odd. My local email client works better than any web based discussion board and supports much better organized discussions than any web forum.
I see the same thing using Firefox and have no explanation for it.
