Comment Re:That explains the spike (Score 1) 233

1) Bitcoin can migrate to new crypto algorithms. The process may not be easy, but there should be enough time to buffer.
2) Eletronic cash systems do not offer anything close to the vision promised by decentralized cryptocurrencies such as Bitcoin.

For 2), it is important to note that the "use of real currency" is far from immaterial. These real cash still have to pass through banks, and it is still ultimately a currency over which a central bank and by extension its government has full control, exactly the thing Bitcoin was trying to avoid. They can use "anything", but before Bitcoin this "anything" would also have been something controlled by a central authority, which in Mondo's case would be Mastercard.

There are many things to worry about Bitcoin, such as failing to properly maintain true decentralization, but some of your concerns aren't valid.

Unlike URLs, it's easy to brute force phone numbers from their hashes. Phone numbers are short and often have low entropy, from what I have seen the arbitrarily assignable part is usually no more than 8 digits, the rest being related to geographic region etc. Even with say 10-11 digits it is trivial for a GPU.

Comment Not so special (Score 1) 86

Many people are simply not so much exposed to these events / competitions, but still go on to become better students at undergraduate level and beyond.

They bring out talent from high school students, but at that point it is still far, far from real innovation. The problem setters and mentors are often university students anyway. These things encourage students to go beyond their high-school curriculum and think cleverly, so they have some great skills to use in industrial or academic settings. They are capable of entering the workforce, capable of joining and growing new businesses, but there is nothing special about their ability to "innovate". They still have a lot to learn, and in terms of cleverness there are many, many comparable university graduates out here.

Inventing really new things require some luck, and unless you're extremely lucky it would require extensive exploration. One page of new mathematics requires lots of thinking and learning. Even a prodigy like Erik Demaine spent 6 years on his PhD. Being smart doesn't mean you can always create something new - new, valid ideas are so scarce and hard to reach, and there is immense competition, so you still need to work hard for a long time to actually produce the results.

Don't mod parent down so much that it disappears. It must stay and be exposed to ridicule. It serves as a blatant example for why people should at least RTFS before posting, and also why this ruling is important - there is an entire rotten culture to be cleared up around unpaid internships, and this ruling is a start.

You shall be ashamed to patronize people for so little that you repay them for their labor. It should also be quite clear the ruling does not apply to unpaid internships that actually have real educational value to the student (it's written right there FFS). Free labor for grunt work is simply abuse; both of students and regular employees. If we let people take these internship positions because "it looks good on their CV" or any other crap like that, it is a race down to the bottom of no benefit to the society.

Goodbye to those kind of internships? If a job like that is lost, we really lose nothing. Paid internships and unpaid meaningful work are unaffected. If a student has to do meritless free labor to gain credits, then the college is equally guilty. The student may as well be jobless, and find a better way to learn something of value - the student pays the opportunity cost, so you have nothing to patronize them about. Everyone doing worthless internships is worse than nobody doing internships, except for the pockets of those abusive employers.

Comment Re: Americans whining "Can't shit where I eat" (Score 3, Informative) 198

Neither does it care about international borders. The fact is that if people in China live their lives like people in the US then their pollution levels and energy spending would only be much, much higher. If you take countries instead of human beings as your base units this way, you would well come to the conclusion that the Chinese should starve because they eat more food than the Americans.
