  1. contracting = 2 x coding on Is There Still A Contract Market For Programmers? · · Score: 2

    Even if you manage full time contracts,
    you coding will only be half the time.
    The other half is consumed by COMMUNICATION.
    Get the proper specs and design.
    Teach the the customer what you have done.
    Promote yourself to the greater community.
    Fix bugs.

    Therefore, take your coding time estimate and
    double it.

  2. Re:a few tips.. on Is There Still A Contract Market For Programmers? · · Score: 2

    There are a few books out there on general self-employment, and specifically for software.
    The Idiot/Dummy series are decent start.

  3. practical computer memory device? on Stop, Light. · · Score: 2

    Basically this discovery exactly remembers a
    pattern of light and replicates it.
    This memory device would be entirely optical
    and fit into photonic computing systems.
    I'd guess density would be pretty good.

    The other optical memory schemes I've seen
    involved continous loops, set and read.
    Another is holographic alteration of material
    optics.

  4. exp(i*pi) - 1 = 0 on E=MC · · Score: 2

    Is another magic equation that encapsulates
    mathematics through the first half of the 19th century.
    I've seen books on individual symbols,
    but don't know if anyone has done all five (or seven).
    I. Shah has done 1, *, =, 0, and -1, and refers
    to this equation. There are dozens of history
    books on pi and a couple on natural logorithms.
    "Want to be a Millionaire" quaestion: what is the
    historical ordering of these symbols (first printed usage)?
    What is the historical ordering of the concepts
    behind the symbols (different answer)?
    The trick answer is that zero is one of the
    latest understood, even though today it
    is one of the first taught.

  5. Book too broad on E=MC · · Score: 3

    The book basically explains the origin of the
    symbol in each equation, from the oldest, the
    equals sign, to the most recent, the speed of
    light.

    I would present it differently.
    I would assume a knowledge of high school physics,
    which is basically simplified Newtonian and
    absolute reference frame, then qualitatively
    introduce special relativity.

    The best quantitative book I've seen is William
    French's "Special Relativity". It only uses
    high school algebra and physics, but is usually
    is offered as an enrichment appendix to second
    semester physics (E&M) at MIT.

  6. blame computer energy hogs on Dark City, San Francisco? · · Score: 2

    Computers and severs are now major appliances
    in many houses and offices. In total they
    consume 15% of the US energy supply and account
    for most of the US energy usage increase since
    the 1980s. Some server farms are measured in
    megawatt consumption according to a recent
    Newsweek article.
    Doesn't need to be that way. Laptop technology
    knows how to keep computing energy to a few watts
    per workstation.

  7. lots of "exceptions" to the coding rules on A Genome Mark-up Language · · Score: 2

    The genome is much like human language-
    a fair amount of regularity plus a lot of special
    cases. In fact the latter throws off decoding
    robots and you see statistics like 98% decoded, etc.
    The scientific papers are full of nifty
    exceptions to what was believed before.

    The markup language would have to be flexible
    enough to encode all the exceptions- perhaps as
    a procedural attachment.

  8. don't forget the cost of conversion on Microsoft, Unisys & Dell To Make New Voting System · · Score: 2

    It would cost tens of billions of dollars to
    change over the country to one of these new
    "improved" systems. Whare does that money come?
    And if it turns out to have serious defects?
    That is why many places keep systems for decades.

  9. car rental denials on The Tightening Net: Part One · · Score: 2

    Credit and driving record databases are now being
    used to screen car rentals at some locations.
    Since it costs a couple dollars each check,
    you don't find out at reservation time, but at
    a rental counter in an alien city. The rental
    companies have decided its worth screwing a few
    precent of their customers at savings of the
    bad apples.

    Driving record databases are sold by states mainly
    for insurance company purposes. But now their is
    a secondary market in car rental screening and
    general credit screening.

  10. credit reports used for employment on The Tightening Net: Part One · · Score: 2

    Some employers now check your credit report
    for employment. Now it is mainly to root out
    thieves. but is the job market softens in a
    recession, they may use any anomaly as an excuse
    not to hire.

  11. stolen SS number? on The Tightening Net: Part One · · Score: 2

    These things are usually tracked by SS number.
    Illegal aliens and identity shifters just pull
    a number out of thin air (perhaps yours) for
    their purposes.

  12. 75% or earth poorly monitored on Sea Floor - Surface - Satellite - Shore · · Score: 2

    A recent study of ocean temperatures says there
    may not be as mouch 20th century global warming
    as thought. Human settlements distort land-based
    measurements. Subsea measurements are rather sparse.

    It would be nice to know better.

  13. recycle old military/commercial cables on Sea Floor - Surface - Satellite - Shore · · Score: 2

    Some people have used/studied old military sensor
    data works and obselete telephone cables.

  14. Carbon has same valence as Silicon on Dawn Of The Diamond Age? · · Score: 2

    In the Periodical Table of the Elements,
    carbon is in the same column as Silicon, one above.
    Therefore it has properties useful for circuit
    design, such as substrates and nano-wires.

    (Conversely biochemists have speculated on Si-based life.)

  15. at least 20 years old on Dawn Of The Diamond Age? · · Score: 2

    I've seen people researching this for at least
    20 years. Radiation hardened military chips
    was supposed an application.

  16. shirt quilts on The History Is In The Shirts · · Score: 2

    I've seen several examples of quilts made out of
    shirts at county fairs and such. Seen some with
    running race themes, politic slogan themes,
    and travel themes. Why not get your girlfriend
    to do a nerd theme?

  17. loser nerd approach on Mapping Internal Communications · · Score: 2

    Using a nerd solution to what is basically a
    nerd problem: poor social and business skills.
    Two wrongs don't make a right.

  18. not sensitive to Earth-type planets on New Planetary Systems Stun Astronomers · · Score: 2

    The current methods of planet detection,
    mainly light doppler shift, can only see large,
    fast bodies- generally larger than a tenth of Jupiter and
    an orbit under two months. This has to do with
    the amount of doppler shift that can be measured
    over a long period of time. Therefore, we are
    going to see the strange stuff first: large and
    fast and probably out of equillibrium.

    Future space-based methods may have earth-type
    sensitivity.

  19. Is C# the answer? on The Object Oriented Hype · · Score: 2

    C# is the first MicroSoft development product I've
    found interesting. (I've been programming five
    years longer than MS has been in existance.)
    (MS was originally a development products
    house before it got into OS and Apps in the 1980s.)

    There are languages that are theoretically nicer
    like SmallTalk and Eiffel, but not as widespread
    or efficient. There are languages very kludgy
    such as C++ or a little bit kludgy like Java.
    C# larns the best from the C family and is likely
    to widespread and efficient.

  20. counter argument: hasn't really been tried on The Object Oriented Hype · · Score: 2

    The same argument as with uptopias, socialist or
    otherwise: many detractors haven't really implemented
    a full OOP project cycle through maintenance and
    re-use with a decent OOP (C++ sucks).

  21. same arguments with printing press 540 years ago on Information Poisoning · · Score: 2

    Before the printing press, books were luxuries
    costing years of an average person's income.
    It was thought dangerous for the average person
    to read the Bible in their own language- they
    might get the wrong ideas. For better or worse,
    the press changed things. New ideas and their
    applications acceleration- first religion, then
    science, and new concepts of government. It
    created a means and market for new authors,
    plus increased reader literacy and customer base.
    The Net continues and further accelerates this process.
    Everyone can be an author,
    not only in print but multiple medias.

  22. if apple would outs ource their UNIX (Mac OS-X) on Dumping LinuxPPC For MacOS X? · · Score: 2

    They'd get more developer attention like Linux.
    However, Steve is not big open source fan.

  23. best severance packages in late 90s on She Was Fired, But Never Told · · Score: 2

    When the European companies bought out the American
    majors, they gave one month per year of service,
    minimum six months!

  24. must complete one orbit to be a "space trip" on Space Tourism · · Score: 2

    You can rent a vomit comet in Russia and the
    USA for a weightless ride now.
    But everyone whos been in space says the earth
    view is most fantastic part.

  25. highest point contests on Another Cool GPS Project: Degree Confluence · · Score: 2

    In Colorado there are peak climbing goals
    such as all peaks above 14,000' (55) or 4000m (98)
    or highest peak in each county.
    No you can try to find the highest point in each
    square degree via GPS.
