  2. MANY ISSUES on The New Ethanol Blend May Damage Your Vehicle · · Score: 1

    Most issues below have been raised above. Many inaccurately, or incomplete.

    Soil v dirt. It is my understanding that to grow anything, all that is needed is something for the roots to grab, and the appropriate chemicals, water and sunlight supplied. True, crop rotation can reduce the chemicals required (Nitrogen a good example, use sub-clover.)

    Grain costs. Ethanol can be made from most organic matter. Grains of any type are good producers of ethanol. The production of ethanol for use as a fuel additive certainly appears to have driven up the cost of grains. For instance, look at a graph of "world grain prices" v time. ( http://www.ifpri.org/node/8436 ).

    It does seem logical that higher grain costs would correlate very well with the increased starvation of people (especially children, about 6 million per annum) in the poorer parts of the world. (e.g. http://www.wfp.org/hunger/stats) There are reports that agricultural areas in third world countries are being bought up and utilized for ethanol production.

    Just incidentally, Ethanol has a lower HCV (Higher Calorific Value) than petrol. (approx 30,000 MJ/Kg -v- 45,000 MJ/Kg.) This means that ethanol is only worth ~2/3 as much as petrol as a fuel, because it only does 2/3 the work. So for a (say) 10% mix (E10) the value per gallon or liter should be (0.9 + 2/3*.1)/1 ~ 0.967% of the straight (ULP) price. Or for each $1.00 paid for regular ULP, the price for E10 should be 3.3c less. For a 20% mix, (E20) the cost should be 6.7c per $1.00 less.

    So there we have it. If you want to (1) help the farmers, (2) damage your car's engine, and (3) help the environment by (4) killing off millions of children in third world countries, then just vote to increase the mandated amount of ethanol in petrol.

  3. A qualification that is cheap and high quality. on Tuition Should Be Lower For Science Majors, Says Florida Task Force · · Score: 1

    The solution is already in process.

    The answer is greater diversity of tuition options, and a professional qualification examining organization.

    Tuition options are already happening, e.g.udacity.com

    Of course if you want to attend MIT for your tuition, feel free. But the final requirement to work as an engineer and sign off on those suspended concrete slabs or elevator certificates or for an electrician's license is the certificate from the examining organization.

    There will still be graduates who pay for university training. And perhaps they will find preference among some employers for their provenance. But some employers will have employees coming up through the ranks, or spot likely talent in interview.

    I suspect that the time to choose a career as staff at a university has probably passed.

  4. Re:Several questions on Supreme Court To Hear First Sale Doctrine Case · · Score: 1

    Some patents are pivotal, like say antibiotics. Or what if somebody discovered a really cheap, quick and accurate test for cancer and charged say $10, 000 for each use for the next 50 years?

    As for copyrights, I think its reasonable that I could record and distribute say a concert that I attended without breaching somebody's copyright. As for books, electronic copies could be provided profitably from an author website for less than a dollar. Even without the copyright system, authors and performers would still live well.

    The social utility and justification for the introduction of copyright and patent law was to provide an income for the developers of novel or artistic works. That social utility vanishes when the owners of those concessions abuse their position to profit beyond the reasonable recovery of performance or innovation costs.

    3. What about patented pharmaceuticals? I could imagine that big pharma might want some input into reselling of their patented drugs back into the US.
    4. Isn't it time we started a political movement to shorten copyright & patent terms, and to reduce rights?

    I worked for a living as an employee in engineering and computing for 50 years.

Someday maybe you will retire.

  8. Re:Source on Huawei Offers 'Complete and Unrestricted' Source Code Access · · Score: 1

    I know that there are a countable number of trigger event types/styles, and each will have only a countable number of options.

    Programming to predict those trigger type/styles would be an interesting problem. Cycling through those options is then a fairly straightforward brute force problem.

    However in the final analysis, even if you missed finding the trigger, I don't see the how the actual event would not be detected by the BB test, or even the timing cycles lost test.

    And if that coding is discovered, it immediately becomes our trojan.

    And neither is the proposed system as bad as you fear. I would imagine that after complaints and investigations, the people suffering with "voter remorse" would be known. Or the actual problem would have been found and the error would have been fixed. Like solutions exist for all your posited issues.

    You raise valid issues. "buyers remorse". "storing identifying information". There are other issues. But wtf, what we have is far less perfect. And there are precautions, and mitigating procedures that could be developed.

    Anything which diminishes our representatives' power (and graft) is good for us, and resisted like the plague by pollies. Direct polling appears to be an important step in that direction.

  18. Re:Open source? on US Election Year, Still No Voting Reform · · Score: 1

    We are at cross purposes. I am not talking about voting machines. "voting day" does not exist. What does exist in this scheme is a publicly available, at all times,
    1). A file of eligible (named) voters.
    2). A file of votes with names encrypted.
    3) open source software that will count the votes, and allow anybody to verify that their votes were properly reported on the vote file at any point in time.

    I do not envisage voting for representatives, but on the decisions that representatives make. When you vote for a representative, you must compromise. No single representative would always vote the way I wanted. And even that requires them sticking to their promises. (haha).

    If the outcome is so close (depending on say 0.1% of the votes cast) then perhaps the vote is never finalized. Perhaps consensus should be sought on a different question?

    There is no machinery, just your own computer, compiler, password, and a mainframe somewhere that holds the master vote and voter files, and open source files.

    Theoretically that master computer could be interfered with, but any change to the votes file would risk discovery the next time the owner of that account looked over his past votes record. (and remember, he could have downloaded the record at any time in the intervening period, so any fiddle would be immediately obvious.)

    Any miscount would be immediately spotted, because every voter could (and quite a few probably would) run the votes file through his/her votes counter program.

    Do you do online banking? Envisage a similar system.

  19. Re:Open source? on US Election Year, Still No Voting Reform · · Score: 1

    The way I envisaged it was:

    There is identifying information on the votes file, (your encrypted username) and the votes file is what is used to count the votes. Only you can verify that it is your vote, and you can see it is not changed when final count was taken. In fact, you could even see if it was changed before and changed back after the vote. Because the votes file contains a historical record of all your voting.

    The open source program suite does the vote counting and encryption and decryption. They also control the generation of the votes file.

    I am on a slow connection, and submit is under the preview button (please fix that, Slashdot) so did not edit out ambiguities in the last response. (below) so read that response before and in conjunction with this response.

    If a percentage of voters (around 5% say) check their vote account for an authorized transactions, and if (say) 1% of votes had been changed by evil people, then there would be a calculated (maybe 50%) chance that the fiddle would be discovered.

    Remember:
    1) the voter file (with encrypted voters) is being downloaded and saved by multiple voters and could be checked for authenticity and vote counting by anybody at any time now and in the future.
    2). The only way a voter gets an account is the one time in his life when he shows up to register. At that time an extra voters name goes on the roll of registered voters, and an extra encrypted account entry goes onto the votes file. The weak point here is that someone watching could note that the two events happened simultaneously.
    3) Any voter could look at any downloaded votes file and confirm that his vote was not tampered with.

    So really, the problem for the bad people is;
    How to change a vote on the public vote file when (1) everybody can see the change, (2) everybody can count the votes.(3) if there was a change, everybody can be made aware and the matter rectified.

    BTW I would make it a capital offence to knowingly corrupt the vote file.

    I think you might have missed one wrinkle that I had assumed. I assumed that an individual could (a) confirm that his own vote had not been tampered with & (b) that he could confirm that there were (say) 100,000 entitled to vote and that there were only 100,000 who were counted (as yes, no,indifferent).

    Now a purist might complain that he could not check every vote for authenticity, however (I can't be bothered with the math, but) if a percentage of voters do check their own votes, they would notice that they had been changed, and raise the alarm.

    I apologize for failing to clarify, and hope this answers your concerns.
