  6. Re:I never really understood bitcoin on The Tangled Tale of Mt. Gox's Missing Millions · · Score: 1

    Bitcoin is actually a distributed peer-to-peer ledger that keeps track of who has the coins. The coins themselves don't actually exist. It's like if you and I both have bank accounts in the same bank and I write a check to you and you deposit the check. The bank reduces my balance and increases yours by the check amount. This works even if there are no actual physical dollar bills in the bank anywhere.

    Mining is doing that bank teller work (increasing and decreasing other people's balances when transactions are requested), and the tellers (miners) are paid for that work with small amounts of the same virtual coins for each transaction they process.

    The brilliance of the bitcoin protocol is how it automatically prevents both the bank tellers (miners) and bank customers (bitcoin users) from embezzling virtual coins or inflating the virtual coin supply.

  8. Use your full name on Ask Slashdot: What To Do With Misdirected Email? · · Score: 1
    In the 1700's and earlier, most people lived in small villages and went by a single name, like "Robert". In the occasional event when there was more than one "Robert", people would add a qualifier such as "Robert the blacksmith" or "Robert John's son" or "Robert from Westford". When people were born in and lived their whole lives in a small village, this system worked.

    In the 1800's, and 1900's with the reduced cost of long-distance travel and the increase of the urban lifestyle, most people lived in communities from thousands to a few millions in size and routinely used two names like "Robert Johnson" and had a middle name to use rarely only to resolve ambiguity such as on official documents and such. Some people use their middle names almost like a password - reluctantly using the name for fear of identity theft.

    IMO, starting in the 2000's, the advent of the global Internet community, population 7+ billion, has rendered the two-name system obsolete. I suggest that in the modern Internet age, use of three names should be routine. The DNS system is actually a good start on allowing people to acquire and keep a globally unique name. Unfortunately, due to the top-level-domain silliness of the DNS system, there could be "robert-millford-johnson.com" and "robert-millford-johnson.net" etc.

    Maybe there should be a top level domain specific to personal names - .name for example. At birth, each person could have a unique domain name assigned to them by their parents. A newborn's birth certificate might show the domain robert-millford-johnson.name, thus guaranteeing the person a unique name throughout life. If people really want to have a password as part of their name, they could have a fourth name not included in the URL.

  15. Re:So long truckers on How Ubiquitous Autonomous Cars Could Affect Society (Video) · · Score: 1

    The truck can drive much more slowly than a human driver. The main reason for trucks to drive fast is to save driver's labor cost. A self-driving truck can drive much slower and get better fuel economy. Delivery time might be slightly longer, but the truck can drive 24 x 7 so for long-haul the delivery should actually get to its destination much faster. Also, short-haul trucking could also be much faster because the shipper doesn't need to wait for an available driver - while having drivers and trucks waiting around for a delivery costs a lot of money, having just trucks waiting around doesn't cost anywhere near as much - so deliveries could generally leave immediately. Medium-haul - say six hours drive would probably be slower.

  17. Re:To put it in perspective on Why We Should Build a Supercomputer Replica of the Human Brain · · Score: 1

    Some interesting optimizations there. Some of them might reduce performance though: for example, researchers have recently discovered that learning involves not just adjusting connection strengths, but also adding new connections. Using a Compressed Storage by Row would require inserting new elements into an array of 100 trillion elements when adding new connections. As long as the AI doesn't learn too much too often, I guess it would be ok :) I guess I agree with you about 32 bits being enough to identify a neuron, as most connections are indeed local.

    The biggest problem with the whole project, as I see it, is the lack of any even halfway convincing comprehensive theory of how brains work. One could argue that discovering such a theory is the whole point of the project, but it seems to me that given the enormous variety of brains in the animal kingdom, and even between individuals within single species, that it should be possible to discover the fundamental operating principles with much smaller brains. I.e. do a mouse brain first with a few TBs of RAM.

  18. Re:To put it in perspective on Why We Should Build a Supercomputer Replica of the Human Brain · · Score: 1

    Each connection needs to specify its own "from" neuron and "to" neuron. Four byte ints aren't big enough for that purpose, so may as well use eight byte pointers for performance. That's sixteen bytes, plus your four bytes for connection strength, so 20 bytes total per connection. All that would have to be in RAM for reasonable performance so the system would have to have at least 2 PB of RAM.

    Considering the number of potential neurotransmitters and possible learning modes, I'm skeptical whether one connection strength per synapse is enough. If each synapse uses a genetic algorithm for learning, each synapse could easily store hundreds of bytes. So the upper limit is probably a few tens of PBs.

  19. Re:Facebook is the old myspace on Facebook To Introduce Video Ads · · Score: 1

    I like this idea, but I see three potential problems with it:

    1) When your computer is off, or disconnected from the internet, no one can access your data. This could be addressed by syncing your personal data across all your devices, so that when one is off, one or more of the others is available as a backup. Unfortunately, this increases the attack surface and makes problem 2 worse. I also don't think keeping your private data in a bittorrent-like swarm would work privacy-wise.

    2) Given the malware-infested state of most ordinary users computers, the app could not effectively protect their private data. On the other hand, if malware broadcasts a user's facebook username and password, anyone can access their private facebook data too, so maybe P2P is not worse.

    3) How would the creator of such a network make any money at all from it? Please don't say advertising! :-) One of the key benefits to the user base of this model is that anyone could make competing (hopefully better) apps that could use the same network and api. The registration info could also be maintained in a distributed database like bittorrent's distributed tracker. The main server would just have to maintain a list of currently active devices participating in the distributed database, keeping hosting costs close to zero. I guess someone could make this thing as an open-source volunteer project.

    What really worries me is the likely automation of military force.

    People will not automate jobs that involve having power over people. For example: legislator, judge, police officer. Even if robots could objectively perform better than people in those jobs, people want people like themselves to have power over them. For example, see all the corrupt and inefficient governments around the world - no one in those countries clamours for a better-run foreign power to take over their country. Also, I imagine that overseeing and regulating an extremely advanced, complex and dynamic automated economy will require quite a bit of intellectual effort and value system work by a very large number of people. Also, childcare - while a robotic nanny might be measurably superior to a human one, would anyone really want their own children being raised mainly by an advanced robot? Also, sports: computers play chess better than any humans, but hardly anyone watches computer chess tournaments. People prefer to watch humans play chess, and I suspect the same would be true for football, or any other sport. Most jobs by entertainers should survive the transition.

    Not really sure why the severance pay rule would be considered "inflexible". All an employer has to do is each pay period set aside an additional 12.5% for each employee's pay into a secure liquid investment. When the employee leaves, withdraw the money and hand it to them. Where does the extra 12.5% pay come from? Obviously, just offer them 8.9% lower pay when you hire them. Pay is lower in countries that have severance rules for this very reason. I don't see anything "inflexible" about it. You can hire and fire whenever you want.
