  1. Re:The 'help' command on The Command Line - Best Newbie Interface? · · Score: 1

    Yes indeedy. Also, since HELP was in the Librarian, which is callable, providing built-in help inside your interactive program consists of:

    1. Notice that the verb was HELP.

    2. Pass command's argument string to appropriate Librarian function.

    Oh, yeah, on MS Windows the GUI *is* a superset of the commandline, and I curse that fact every single time I need to script some simple sysadmin. function so that it can become a regularly scheduled batch job and handed off to the computer instead of me continuing to do boring repetitive manual labor.

    Any GUIfied product with no commandline equivalent is only half implemented.

    Anyway, there *are* CLI graphic composition programs. Take a look at POV-Ray. There *are* CLI programs for composing beautiful text, such as TeX. Whether you use these, or WYSIWYG products, depends on how you choose to think about the problem.

    Many man pages suffer from trying to be too comprehensive. Fully explaining 'cat' doesn't take a lot of text; fully explaining Sendmail could cause someone's head to explode. A system that has worked well for me is to pare down the help to just a quick summary of the program's task, reminders of every little switch's basic meaning, and liberal use of "see the manual for details". In the manual you find copious examples, full discussion of subtleties, and suggestions for use.

    Trouble is, on Unix 'man foo' *is* the manual. If we didn't have the silly war between 'man' and 'info', then 'man' could be the reminder help and 'info' could be the manual, each with appropriate styles for their divergent purposes.

    perltoc.1 is more than half a megabyte, for cryin' out loud! That's way too large for a man "page".

  6. Re:The 'help' command on The Command Line - Best Newbie Interface? · · Score: 4, Insightful

    I will now reveal just how uncool I am by suggesting that you go take a look at the OpenVMS 'HELP' command. The wealth of information in a decent man page is like a revelation from heaven to one who has had to make sense of DOS HELP, but a single massive spew of everything known about some complex program is a little overwhelming even with an outstanding pager to help. VMS HELP documents are hierarchial and are usually chunked fairly nicely.

    Where VMS HELP falls down is in full-text searching, though that may have been improved since they took my VMS boxes away. It also needs a much better pager.

    'info' is pretty good, but there are a number of very poorly structured texinfo documents to deal with, the style suffers from doing double duty as the revisable form of a book, and somehow I've never reallly become comfortable with the keystroke assignments. OTOH texinfo's structural possibilities are a bit more flexible than the VMS Librarian's HELP mode, and a good document designer can do wondrous things with it -- the problem is the dearth of good document designers and a certain attitude in the community which says that documentation is for those who can't read source.

    People. Materials. Manufactured goods. That "permanent presence" is not a dozen astronauts living in an airtight Quonset hut; it's a bunch of communities forming a self-supporting society. It'll take generations, but I'm convinced that it will happen.

    The early European settlers in the Americas didn't bring 21st-century Baltimore or Buenos Aires with them, rolled up *really* small and packed belowdeck. They brought a few essentials, but mostly they brought themselves and the will to make what they needed. The cost was frightful, but there's always a market for "a heap of unexploited resources and the chance to see what I can make of them".

    An entire uninhabited world is a pretty big heap of resources.

    The same thing could indeed be done "direct to Mars". But the Moon's a lot closer, we already know we can get there, we already know what we'll find, and the kind of *sustained* contact needed to build a functioning society is a lot cheaper when the distance is less. You could also think of a lunar colony as a pilot project for real interplanetary expeditions.

    Back to the "standing a mile high" ideas: the big beam has only one point of failure: it falls over every time you let go. The tower has many points of failure, but the failure of one or even a dozen won't bring it down (if it's designed right). It costs a lot more because it's *worth* a lot more: it'll survive long enough to recover its cost. And the tower's complexity is what buys you that fail-soft property. Complexity and expense are not bad things, as long as you get something worth at least what you paid.

  12. Re:Goals on Glenn Urges Direct-to-Mars Trip · · Score: 1

    Indeed, if the goal is to do science on Mars then Moon missions just waste time and money. Why not just go to Mars, poke around, go home, done?

    But there are other, perhaps better reasons to establish a permanent presence on the Moon and a regular transport pipeline between here and there. Eventually the same reasons will drive a buildout of solid infrastructure to all of the useful places in the solar system. It's a lot slower and more costly but it's also a lot more sensible.

    Think of two ways to stand a mile in the air. One way is to manufacture an I-beam about a mile long, weld rungs to it, and stand it on end. Not very stable or permanent or safe. The other way is to manufacture a thundering lot of I-beams in normal sizes and fit them together into an Eiffel-Tower-like structure, then add elevators. I know which one *I'd* feel safer ascending, and which one I'd expect to still be standing ten, or a hundred, years later.
