"Passwords must be changed frequently and must contain at least one uppercase letter, one lowercase letter, one number and one special character, and must never be written down" must be the worst security advice ever.
Bad:
* The probability of guessing someone's password increases only marginally if it is unchanged.
* Frequent password change just makes the users add sequence number or the month name to the passwords.
* All the character category requirements induce only bad passwords in order to be able to remember them.
Better:
* Write down complex passwords and keep it in your wallet along with your 100 € notes, which you never want to lose anyway.
* Simple password complexity evaluation algorithm, e.g. adding points to length, and the number of different characters and such.
* Lock any account that is not used in some time interval, and use some other mechanism to unlock it, e.g. human administrator, email, SMS or extra long password for this purpose.
Here is an app idea for you. Viewers watching a sports event push a "Wow!" button whenever there is something interesting happening in the game. These are the "producers". A "consumer" records a number of sports events and the playback device (a PC) shows only the interesting parts. You can now watch a lot of games simultaneously!

Seems to me that the solution is to have a strong password and keep your computer free of malware.
Is that really so hard?
So you didn't read the paper, or how do you defend the use of strong passwords that the author did not think of? Anyway, if there is only "your computer", then things are significantly simpler. A typical user has to remember at least 20 passwords all over. (Waiting for the Slashdot poll "How many passwords do you have to remember and how many of them are different?")

To that end, using a darknet is actually reducing how free you are because you're not standing up to the authority or laws you're circumventing. Freedom is being able to do what you want to do without having to hide it.
This is not true. Freedom is whatever makes you feel free. With your definition, noone is ever going to be free. In small societies, you don't find many "odd men out" because any of them keeps quiet, like gays or other political incorrect individuals.
Anonymity and stepping forward and outing yourself whenever you decides yourself is freedom.
A great way to frustrate that showoff cuber at the office. Especially if they appreciate it when someone scrambles the cube and they'll have it solved in front of everyone. Just go and put it back together randomly, or do one of those devious swaps, and you'll have fun watching him try to solve it.
An RC (Real Cuber) knows this automatically. (S)he just says that it is unsolvable without cheating as the troublemaker just did. Actually, my method for solving the cube always implies just looking at some of the edges and corners as I know that the others have to fall neatly in place.
Next case, please.
There is cod and there is cod. The cod fished outside the northern part of Norway is not overfished due to heavy regulation, but it is threatened, not at all by (legal) overfishing, but by illegal fishing, by (potential) oil spills, by other pollution and by global warming. There is a long time tradition to produce cod liver oil in this country, and there are products that extract the good part and remove any heavy metals that inevitable are a part of the cod's liver. Here are some refs:
There are also a lot of studies that confirm the health aspects of this substance. Of course, most of the studies must be read carefully, but I do find this interesting anyway. Other refs:

The good thing is judges understanding GPL. I didn't think we've got that far, but it seems I am wrong. Knowing a lot of lawyers in Norway, I have different experience.
But I think the "magic" here in LISP is that by going at it with macros and using those to change the appearance of your programs, you're providing a sort of cognitive shift to the programmer where they can think about each category of problem in the system as a "mini-language". That renders a way for the programmer to feel like they're in control and like the solution feels more elegant, because it's less encumbered by syntactical baggage. Is that about right in your experience?
This is exactly how I feel. The thing that most people forget with programming, is that it is a tremendous abstraction workout. When someone tells me that he can do everything in his or her favroutie language, the person is just clueless. You actually need to work on an effective abstraction layer to be able to build anything. Lisp is just today the most suitable language to rapidly make your own abstraction layer.
In fact, computer sience as such is not only algorithms, formalism, social impact and all those things discussed endlessly, it is also the sicence of abstractions and even more than any other themes you'll might find.
The bad thing about macros, is that it can slide out of your control, thus making a language not even you yourself can understand.
This is like saying "You should not sing for your children because it under-cuts the music industry."
Actually, I think there are undiscovered opportunities in the open source industries. Consider to start a programming/consulting business that exclusively deliver open source products? A customer who wants some sort of application will not need to pay for the complete program, because there should be a lot of modules existing out there that can be customized. The client will not own the finished source code, that is true, but why should a customer who really only needs the end product, care? Moreover, the customer can benefit from any later improvements made to the product afterwards.
This is like we all benefit from scientific discoveries or methodology improvements in, say, the house building industry.
This is sad. The most important aspect of the 11/9-attack is that it was purposefully. It is said that one can bear a tragedy when it is a result of an accident or a natural catastrophy. However, when you are a victim of some action carried out by purpose, you live with your grief the rest of your life. This makes, in some sense, the Twin tower attack much worse.
However, I find emotionless sarcasm in your message. Why is that?
If you don't want your ISP doing things like this then don't use a big mainstream one that caters to the great unwashed masses.
Well, I would hate it when my ISP does something like that to me when it is not a part of my subscription deal. It is too easy for such methods to be misused in the future.
I am amazed that noone find this unhealthy due to mere principles.

Well the reason the technique was originally invented was that the DOD was spending way too much money on software maintenance.
What "technique"? The OO-technique? Well, then I am glad to inform you that it was not invented by the DOD. Simula was the first OO-language ever, and it was invented by researchers at NR.
Even without ACLs, [Linux security mechanisms] is more than adequate for 99% of companies.
This sounds like "640 KB is more than enough". Actually, I often have problems in setting up security domains for projects at the university. Imagine a CVS project where you must use the campus wide file system to set up a reposotory and where you wish to give read/write access to different users in different sub projects. The Linux native access control mechanisms are not flexible enough.
One way to look at such problems is that the reason that something is good enough, is because users don't know better. Like my grandfather who could not understand the use of planes.
I am really impressed, as it is the first time I convert someone over 30.
In some sense, I think the 20-50 are the most difficult to convert, because they think that any criticism against Microsoft is an offense to their manhood.
Those above 50, on the other hand, do connect their choices like that.
The Scandinavian languages are of Germanic heritage, while the Finish language is of Slavic heritage.
Actually, Finnish is a Finno-Ugrian language and is less related to any other European language than Persian or Hindi. See e.g. this

Understanding Swedish for a Norwegian is like understanding cockney for an Englishman.
Yes, this is probably true. However, few Swedes understand spoken Norwegian. (We have to blame TV for this one.)

...and lock accounts after 3 to 10 incorrect attempts.
Yes, of course. That fell out. Thanks. We also use automatic unlock after N minutes so brute force attacks don't work.
