(Warning - long and boring rant ahead) Once upon a time I tried to create a distribution system which (among more important goals) would make it possible to have parts or the whole of a copyrighted file on a computer with plausible deniability (and making it hard to prove that it's there). The distributed caching system was intended to ensure that parts of popular files were cached more than others so that one node that cached many blocks could with a high probability have all parts of a copyrighted work even if the node user(s) never intentionally downloaded it.
The solution which I _think_ would make deniability possible (and more importantly making the aggressive caching realistic) is to divide all files into blocks (where blocks could be overlapping), use one-time pads for encryption, store the procedure to extract a file in the same kind of blocks.
But the trick would ensure that each block can't be tied to a specific file (or even groups of files), so the blocks have to be reused. As they are encrypted they can be considered random - so they can be used as the one-time pads mentioned above. So to upload a file one 1) divides it into blocks 2) encrypts the blocks using either pseduo-random data or another existing block. There can be several overlaid blocks in practice - logical exclusive or is used for mixing them, blocks needn't be a uniform size so the block(s) selected as keys also have associated position relative to the block to be encrypted.
The final step is to encode how to create a file: a list of identifiers of required blocks, a list of how they should be combined, file names etc. This is generated as one or more blocks (very unlikely to be needed) and encrypted with a pseduo-random stream. To begin to download a file one have to know the (first) block that contains the descriptor, the seed for the random generator and some other things (including an index into the block). This can be stored as a 256 bit number - a file identifier. Several identifiers can map to the same encoded file, one identifier can specify several ways to extract the same file etc.
There are more things that are important for this to be opaque legally including making sure that all nodes cache popular blocks, that all kinds of blocks are promoted to ensure survival of rarely accesses blocks, that blocks are ensured to be error free and that nodes that fakes blocks can be detected and blacklisted.
Stopped working on the system as making the search system scalable, anonymous and tolerant of statistical analysis was a problem - even for the lower limit of presenting a plausible deniability for copyright violations. For some things if statistical analysis point out a user as a _possible_ distributor it may be enough to severely damage the user.
I can tell you never programmed a computer. Patches software accumulates cruft unless periodic cleanups are done. Doing cleanups tend to create bugs. Rewriting code should use the experience from developing the original system - given a competent programmer or team of programmers.
A suggestion for you to research: lookup the crimes committed by people with "non-traditional British name" and those with "traditional" "British name". Then look to see if non-traditional naming is linked to increased criminal activity. I'd be genuinely surprised if that would be the case.
... that couldn't run in MSDOS because my computer at the time had too little memory. Booting into OS/2 and starting it worked great - and the fact a large chunk of memory was virtual and on a HDD caused no problems.
OS/2 was created as the next generation DOS, the first versions didn't even have a GUI. And it was a very good DOS.
Quoting Ayn Rand means having read her work - having read her work can lead to a serious case of mushy brain. Don't do that.
Her works are illogical, unrealistic paintings of a terrifying world where psychopaths are the ideal. She never followed those ideals herself BTW instead choosing to be a leach on so many levels...
Media have always provided what the masses want to see. Not only tabloids (which only makes the skewed reporting more visible), not only politically motivated publications but even media that intends to provide unbiased facts. Until we can create real AI with no bias to do our reporting can we expect that to change - all humans are biased, at best we can be aware of that and try to mitigate somewhat.
But even when we have AIs we will still get biased reporting. That's the way we want it - that's the way we gonna get it.
So the boss telling the secretary that just threw a tantrum a baby is creepy and revealing? Would it be creepy and revealing if the boss is a woman? Just wondering...
Those are commonly called TUI (Text User Interface) in comparison of GUI systems. But the difference between them needn't be huge, there are GUIs that look like TUIs and vice versa.
I can't prove you aren't an alien (of the space kind) or aren't retarded. However the indications available would make both of those things very unlikely just as law enforcement using jammers is unlikely as it would be easily detected.
There are a lot of people that worry about killing animals, that includes many scientists. A lot of thought is spent on deciding IF an animal study is needed, HOW the study should be done to minimize suffering etc.
I think you don't know shit about what you are blathering about. There's nothing metaphysical about what a human is - it is a definition that's decided by the collective. That definition have changed often too, Africans were considered sub-humans (and still are in some places), Jews too (still are in some places). In war situations the enemy is always painted as sub-humans, this because for a human soldier it is easier to kill "the enemy" rather than another human.
When pigs, dolphins and elephants can be a part of the human society then they can make their voices heard and be considered part of humanity. Before that happens what you are blathering about is a subset of philosophy - not science.
Swine flu can already infect humans, many human diseases can be transmitted to swine. I don't think this is a large problem and even if it were experimental scientists already have experience in breeding under strict controls - mice without immune system wouldn't live long otherwise.
Hydrogen peroxide isn't in itself an _explosive_ so trying to paint it as high(ly) explosive is simply wrong. It is highly reactive though which means the storage and distribution of it have to use very clean, compatible materials. Rest assured that nobody sane will use a catalyst instead of a compatible material!
You have a fundamental misunderstanding what siphoning is and how it works. Siphoning only works when a higher placed reservoir transfers a liquid to a lower placed reservoir, it doesn't allow for a pumping action from a lower to a higher reservoir - which is why pumps are used for that purpose.
I think we all should encourage would-be-terrorists to make acetone peroxide given the high chances of them blowing themselves into pieces when making it. Even for amateur pyromaniacs there are much safer stuff that is only marginally harder to make than the mother of satan...
Large parts of Norway, Sweden, Finland and Russia will probably never have practical solar power. Even in the summer the efficiency is relatively bad (due to the angle of the sunlight) and when energy is needed the most in the winter the northern parts have almost no sunlight at all.
Really? No idol of mine - just another hyped-up salesman. My idols are those that strive to improve the life of others via technology, social work, opposition to extremists of all kinds or just trying to make a difference.
It's cute when someone think there is _a_ government. This is simply not true. Even if we ignore the fact that the US is made up of several states with separate governments (arguable with several layers of sub-governments) and treat it as a single entity it isn't true. It isn't even true in totalitarian states with a tightly controlled government apparatus! It is a paranoid fantasy, a convenient us-vs-them scenario being used as a scapegoat for things perceived as impossible to change, easier than realizing the frightening truth: people are dumb, stupid, panicky animals - and governments consists of people.

It would be copyrighted.

In the same vein I didn't fuck your mother - yet.
Bull.

So what the fuck does "SJW" (something I've only seen used by trolls and bigots) have to do with that position (that it doesn't matter)?

You use SJW -> you are part of the problem. Idiot.

As a monopropellant is isn't great but I wouldn't call it lousy, in practical use it isn't actually a fuel - it is the oxidizer.
But yes it's nasty stuff in high concentrations.
