Comment: Re:XOR is useless (Score 2) 277 277

Funnily enough, XOR is used in a number of encryption schemes, but for it to work you've gotta make a bitstream to XOR the plaintext with. Like, encrypt a random value, then re-encrypt the result, repeat over and over, then line them all up and use that as an XOR pad.

Comment: Re:Skylon (Score 1) 96 96

One big issue with Skylon is that it's an all-or-nothing deal. You can't send anything up until the whole thing's done. On the other hand, Falcon 9 Reusable is an adaptation from a conventional disposable rocket. The disposable version's already flying at a profit, contributing both money and experimental data towards the design of the reusable version.

I get what they're trying to do, but this seems like the wrong approach. You don't fix discrimination with more discrimination, even if it's in the opposite direction.

Seems like it would be better to find out why the industry is so racial/gender imbalanced, and try to solve that problem (whatever it turns out to be) rather than covering up the symptoms.

Comment: Re:yayy!!! Cheer our corporate fascist state! (Score 2) 87 87

Oh for goodness sake... governments pay companies to do things. It's normal, it happens all the time. (Ford makes police cars, for example.) Even when the government "does it themselves" there are usually contractors involved. The difference here is that the deals with SpaceX and Orbital are more hands-off than the old ones with Boeing and Lockheed. (And also cheaper -- Flacon 9 costs a lot less than Atlas V or Delta IV.)

Fascism, from my understanding, originally meant a system where the government controls corporations. It has more recently come to mean a system where corporations control the government, or a system where individuals have litte or no freedom. Regardless, none of these really has much to do with the contract SpaceX is working under. Yes the government is heavily involved (helping pay for development in addition to the launches themselves, etc), but compared to traditional contracts it's a step away from corporations being intertwined with government.

While the intention was definitely good, I personally would not want to use a machine that the could be remotely accessed in such a mannter.

True, something like anti-virus software self-updating and removing a threat would be acceptable to most users. But this is more akin buying a car and discovering the manufacturer has a master key and a representative can come over and drive it around whenever he/she wants, and it's fully legal and you can't do anything about it.

In the end, for better or for worse, I think it's important that we actually own the devices we buy and pay for. Cases like this, and similar ones with Kindles and mobile devices remotely being accessed and modified or used to spy on us, are strong evidence that we do not. (I know that this particular case is not a big deal in of itself, but the fact that Microsoft can do what it did is not good news.)

For a lot of predictions of future tech, we eventually wind up at a point where we have the technology, but no one's really interested. Things like voice-activated elevators, for example. We could make those easily in the present day, but almost all of us would rather just push a button.

I think in this case most people would rather have something that fits in their pocket than something sewn into their clothes.

But an end to Moore's Law has been predicted before multiple times, and it hasn't happened yet. (Things have slowed down, yes, but they're far from stopping.) A few years back hard drives were predicted to reach a storage density limit, but this was solved by turning the magnetic cells vertical. So Moore's Law may finally be coming to an end, but don't be surprised if something new comes along and blows silicon transistors away.

The problem isn't that girls are denied an opportunity to learn coding when in college. The problem is that they're denied this opportunity when they're younger, they're told it isn't for them. Here's a good illustration. To solve the gender discrepancy we need to go for its roots, not try to cover up the symptoms.

Well that, and there's the sexual harassment issue, but the same thing applies. Don't try to force girls into computer science; make the environment more comfortable and welcoming, and they will come on their own.

Never say you know a man until you have divided an inheritance with him.
