  1. Goodbye and thanks on Rob "CmdrTaco" Malda Resigns From Slashdot · · Score: 1
    I wish all the best for you.

    I haven't posted for (what seems like) decades, and this is probably my last post.

    But I still read almost daily, and I hope the site stays true to what it was.

    A solution is already emerging. Did you notice how people are tagging with !gay? As soon as Taco picks that up and starts using "!tag" to cancel "tag", we're back on track. An by the way, I think "gay" was due to the pink scheme, but that's just me being a homophobe, I think.

  4. Re:digit extraction on 83,431 Recited Digits of Pi · · Score: 1

    Details here.

    Quick answer: it's not.

    Long answer: You still have to sum lots of terms (around N terms). The idea is to multiply the whole sum by 16^(K-1), where K is the digit you want. Now this digit is in the first decimal place.

    To illustrate, these are the first few iterations of the formula:
    n = 0: 3.222222
    n = 1: 3.222222 + 0.021221 = 3.243443
    n = 2: 3.243443 + 0.000ACE = 3.243F12
    n = 3: 3.243F12 + 0.000055 = 3.243F67
    n = 4: 3.243F67 + 0.000003 = 3.243F6A

    If you want the 5th digit ("6"), you still need to do the sum, but you multiply by 16^4 and get:
    32434.43, 3243F.12, 3243F.67, 3243F.6A

    The trick, finally, is that you don't really need the integer part in the calculation, making it much easier to evaluate.

    I have been using unison for about a year. It used to have some minor flaws, in particular when synchronizing large trees for the first time, but it never lost or corrupted data. It required several restarts until the trees are identical, then worked fine. It is probably fixed by now.

    And I can confirm that it runs on Mac OS X and Solaris. There's even a native GUI for the OS X version, which I never tried.

  13. Open Source Currency on The Open Code Market · · Score: 1

    An alternative idea is to introduce a community currency: (this was presented in the Future of Money summit)

    Open source needs a system for motivating participants to both stimulate activity initially and to keep people involved for the long term. complementary currencies need a community within which to operate, and an equitable system for exchange. Together they can dovetail nicely.

    Just as complementary currencies are not intended to replace national currencies, open source projects are not intended to replace people's regular jobs. However, creating some form of remuneration for their time and effort can allow people who are not working on a "paid gig" to find a new home, making a meaningful contribution, with some nice side benefits.

    The currency designed for open source projects would most likely be an hours-based currency monitored by the number of actual hours spent working in some trackable development environment. A separate open source exchange site would enable people to redeem the hours-based currency for good and services posted on the site.

  14. Re:A bazaar in cathedral clothing... on The Open Code Market · · Score: 1

    Well, it seems that the idea was not original: Open Source Currency. This was presented in the Future of Money conference.

  15. Re:A bazaar in cathedral clothing... on The Open Code Market · · Score: 1
    Very true. But I believe this paper underrates the strength of (as Eric Raymond calls it) the gift culture. Essentially, OpenSource developers compete to give the biggest gift to the community. The bigger the gift, the more their standing within the community rises. This has worked pretty well the past 13 years or so.

    A gift culture is not orthogonal with a money-based economy. There is an interesting work by Bernard Lietaer (The Future of Money) that deals with the effect of complementary community-based currencies. In summary, if a community creates a local currency with which to back local transactions and reward gift-givers, the tradition can even be strengthened.

    The key, for him, is "community-based". He gives some examples in the web site above. These currencies are non-scarce (currency is created when a transaction happens) and backed by the work capacity of people (some of these currencies are traded in work-hour equivalents), not by bank debt or government fiat.

    I've been thinking about means to apply this to the open-source community, but I'm not an economist. Basically, you would receive "open source credits" for creating new code, and you could use these credits to pay for the creation of code that interests you. This is basically trading your time with the time of others, and fits well with what Lietaer describes in his book.

  16. PDA maps on Best Online Mapping Site? · · Score: 1

    Does anybody know of a good PDA application with reliable maps? I don't care much for driving directions, I just want to have a map that I can search by street name and number, put some custom markers and find out where I am. Downloadable driving directions would be a plus.

    I am currently using Rand McNally's StreetFinder with a free sample map, but the interface is not ideal. I would like to spend my money on something better, if such thing exists.

    It also bothers me that it cannot find my address (which is at a reasonable big street), although it will show the street name in the map.

  18. Re:Won't happen for a LONG time. on A Hydrogen-Based Economy · · Score: 1
    Can anybody tell me why we can't just run on an alcohol?

    Alcohol has been used in Brazil since 1975, when the government launched the Proalcool program as a reaction to an oil crisis. My family had an alcohol-powered car. From what I recall (you can google Proalcool if you are interested), the problems were:

    • Alcohol was not competitive with gasoline, and needed heavy subsidies;
    • Even with subsidies, sugar was more profitable for cane farmers, and there were supply problems;
    • Alcohol cars (before electronic injection) were a pain to cold start, specially early in the morning -- the population learned to dislike them;
    • After the oil crisis ended, there was simply no incentive to continue the program.

    Today, all gas stations still sell alcohol, there are still some cars being built for it and our gasoline has a fixed percentage of ethanol.

    We have also a growing percentage of cars powered by methane (sold as 'vehicular gas'). We have had gas-powered buses for a while, and cab drivers are actively converting their cars.
