  1. Re:No fortran - just Python on Should Undergraduates Be Taught Fortran? · · Score: 1

    The key thing is that it is algorithms what are more important - and these are easier to write/learn in Python - so it students should learn Python first and only some need to learn fortran..

    Uh, well, no. In the areas where Fortran is still dominant, that is not the key thing at all.

    What is most important when developing a new airplane wing, flu vaccine, or artificial respirator for use during heart-lung operations, is that the libraries used for the complex math formulas are completely debugged and totally trustworthy. That requires the use of a language whose source code is simple for humans to read and critique, and whose compilers are fully transparent in the way they handle optimizations.

    Python is a great scripting language (even though I personally dislike it).The Python with C optimizations that parent post describes is an excellent way to make business logic systems, build games, or construct an EssayGenerator that will give you a passing grade in Writing 101 with the push of a button. But Python is not a very good choice when a failure in accuracy in some unlikely edge case would cause death. Fortran is a better choice in that context, since it was explicitly designed to avoid those kinds of problems that can arise between source code and implementation.

  2. Re:Oh come on. on Should Undergraduates Be Taught Fortran? · · Score: 1

    These are undergraduate students. It is safe to assume that each and every one of them has been writing programs in high school in Python, Perl, or Ruby. And that all would have some skill in Javascript. Fortran would not be their first language. And... they are bound to arrive with some bad coding habits already established.

    Fortran makes sense as an undergraduate course as it maps better to the realms of engineering and science than the C based languages, the Lisp based languages, or the Pascal language groups. In particular, I think Fortran would be an excellent choice to drill students on the rigors of structured programming. Fortran is also directly relevant in many of these subjects as it remains the best language ever for developing and maintaining libraries of differential equations and other exotic mathematical menageries.

    My direct experience with Fortran is limited: an introductory course in 1972 that was seriously bogged down by us students having to transcribe our coding sheets to Hollerith cards. There were an adequate number of key punch machines, but most of us were hunt and peck typists back then, and the process was slow, error prone, and caused much anguish.

    My indirect experience with Fortran is similar to everyone else's: for instance, I rely heavily on the Fortran libraries that were written in the 1950s every time I fly in a commercial jet, since those Fortran routines are still used to design wings and such.

    Taking this back more toward the original topic: Are there any other planes or boats that were lost or damaged by the same storms?

Getting hit by debris carried aloft, that maybe had been in free fall for 1,000 feet, could be as nasty as getting hit by a meteor, and I think a lot more likely. Something like that hitting the windshield would be bad.

    For that matter, a waterspout could have lifted any of the non-plane debris that has been found from the waves to a height where the 100 mph updrafts (9,000 ft/min) could have grabbed it and taken it up into the jet.

    What gets me about driving in crowded freeway conditions is the amount of faith we have in the technical abilities of perfect strangers. In a one hour 50 mile drive between two cities during rush hour, a driver has to have faith that all his nearest neighbors can keep their vehicles within their small envelopes of safety, and that the neighbors of all those neighbors will do the same, and so on. And these aren't static cadres; new drivers are constantly filling the gaps as others reach their exits. Under these conditions, your health and safety are dependent on the abilities of perhaps a hundred different strangers to operate their lethal machines within very narrow constraints, and to cooperate with you and each other.

    It can make one recognize that the belief in humanism is more powerful, and more common, than the belief in any god (even if it is rarely recognized).

    Above was certainly true at the end of the last century, but it is less and less the case. In the USA, there is an increasing awareness of Linux through the "I know this guy who has a friend who has changed to Ubuntu and he says..." channels. The buzz is that Linux comes with a large package of good software and it is easy to get more. Elsewhere in the world, where more people get their news more from other people than from idjit boxes, I think the word is spreading faster.

    As a wag, the Linux adoption curve is probably very similar to the Firefox adoption curve, stretched out somewhat. That suggests to me that probably 3% of the "market" are using Linux several hours each week, and probably an additional 4% to 5% play with it every now and then, either as a dual boot or from a CD or USB device.

    I think a telling point is that in Costco and other big box stores, the display area given to software has shrunk dramatically over the last 5 years.

    2. I have yet to meet anyone new to Ubuntu who did not like the Update Manager, especially after being shown how to configure it for daily checks.

    On a somewhat related note: the machine I'm typing this on is a Dell that came with WinXP installed, and now has a dual boot with WinXP and Ubuntu. Since the WinXP partition is about a third of the hard disk with the Linux partition taking up the rest, should this machine be counted as 1/3 Windows and 2/3 Linux? Or would the temporal distribution be more appropriate, in which case it should be counted as 5% Windows and 95% Linux? These fancy statistics... I get so confused!
