    You had backspace? I had to disconnect the carriage and slide it to the left.

    Wow. It's been over three decades since I've touched a manual typewriter, but I can still remember the feel of the backspace key, with the extra force it needed to drive the carriage right.

    The article states they can only get it to +3 psi, but does not say why. (I'd love to know.) Perhaps instruments (maybe avionics and other displays) inside the shuttle should not be exposed to more than 18 psi absolute.

  7. Mutualism vs Symbiosis on Microbes 100M Years Old Found In Termite Guts · · Score: 3, Informative
    From the article:

    Without the protozoa, the termite would starve. Meanwhile, the protozoa would quickly die outside of the termite, resulting in a relationship of dependence between the animals that scientists call "mutualism."

    From the Symbiosis article:

    The definition of symbiosis is in flux, and the term has been applied to a wide range of biological interactions. The symbiotic relationship may be categorized as being mutualistic, parasitic, or commensal in nature. Others define it more narrowly, as only those relationships from which both organisms benefit, in which case it would be synonymous with mutualism.

    Hmm, live and learn.

  10. Re:Their country, their loss! on Thai Gov't Sets Up Site For Snitching On Royals' Critics · · Score: 1

    I wouldn't make any Thai travel plans for the foreseeable future.

    One small advantage of traveling now is that in an effort to encourage tourism the government has waived all tourist visa fees through 4 June. Last week I received a 60 day visa (extendable to 90) that would normally have cost me 110 Ringgits.

    Note that when arriving by air, citizens of 40-some visa-exempt countries receive a 30 day visa on arrival -- always free -- but many wishing to stay longer used to make a "visa run" to a neighboring country such as Myanmar or Malaysia to get another 30 days. Just this year they started giving only 15 days at the border crossings, making advance visas more attractive.

  14. Re:Newsflash on Study Suggests Crabs Can Feel Pain · · Score: 2, Interesting

    On Potter's Cay in Nassau I saw a strange fruit for sale -- a rather flat oblate spheroid, neatly arranged on the table in rows, with what appeared to be multiple stem attachment points on each fruit. I hadn't picked one up yet when the vendor misted them with water from a spray bottle and then put a pinch of grain meal on top of each, which the "fruit" then ate. They were crabs with their legs torn off, presumable for easier storage and display. I assume that the legs were sold separately. Is anyone here familiar with this practice? I've always wondered how long the crabs can be kept that way.

    [From AMBER Alert#Activation criteria]

    #2 The child must be at risk of serious injury or death

    Many law enforcement agencies have not used #2 as a criterion, resulting in many parental abductions triggering an Amber Alert where the child is not known or assumed to be at risk of serious injury or death.

    [and later from AMBER Alert#Falsealarms]

    A Scripps Howard study of the 233 AMBER Alerts issued in the United States in 2004 found that most issued alerts did not meet the Department of Justice's criteria. Fully 50% (117 alerts) were categorized by the National Center for Missing & Exploited Children as being "family abductions," very often a parent involved in a custody dispute.

  17. Re:TI on Celebrating the HP-35 Calculator With a New Model · · Score: 1

    RPN is so overrated. ...by decomposing every equation

    Perhaps this is similar to a personal preference for standard vs. automatic transmissions, but I feel that this required decomposition is one of the main advantages of RPN, as it involves active interaction with the equation. Students who simply type in an algebraic equation and press EVAL seem more likely to view equations as magical formulae, accepting results without question. Intermediate results, calculated and displayed via RPN, have meaning and are often identifiable quantities.

    I feel that the most vocal criticism of RPN comes from those who are not sufficiently comfortable with math to effortlessly decompose equations. These are the students who would benefit most from regular use of RPN, as the mathematical facility developed would help them better understand even those equations they do not evaluate.

    An infix calculator is in many ways "smarter" than one that only accepts RPN. (Think of how few lines of code are required to implement an RPN stack.) What do you want your calculator to do for you? If you want it to do as much of the math as possible then choose infix. If you are willing to do the math and want the calculator only to do the numerically accurate computation then choose RPN. (Are you really going to evaluate 2*sin(pi/6)?)

    I do realize that this is similar to the lamentations over the disuse of slide rules, and students' resulting cluelessness with regard to the expected magnitude of an answer. Perhaps the only difference is that once the skills for rapid use of RPN are developed there is no speed advantage in "graduating" to an infix machine.

    If you care so much about numbers, start using SI units, please.
    Hunh? I used the units used in the chart. Are you suggesting that the authors, by using units common to the industry, abdicate their responsibility to makes sense of the numbers (an admittidly easier task with SI units).


    In any case, I am not troubled so much by their being off by a factor of 10^6, in essence a typo, but by their beleiving their typo ("only a fraction of current U.S. annual consumption" -- technically true, as 3/4 is only a fraction), and providing meaningless entries for the solar and wind columns.

    15.9 million cu. ft. of natural gas -- only a fraction of current U.S. annual consumption

    More likely 15.9 million MMcf, or 15.9 million million cu. ft, a large fraction of current U.S. annual consumption (21.9 million MMcf in 2005). An average home consumes 6 Mcf (thousand cubic feet) in a month, and the gas consumed by 2500 homes in a month will not power the nation's cars for a year.

    Additionally, solar and wind densities do not compare to absolute amounts of coal and biomass required annually.

    Solar: 2500 kilowatt-hours of sun per square meter per year
