|Can we use ruby for commercial
 |application?

 Yes.

 |Do we need to distribte our application with sources?

 No.  If you're using regex.c comes with 1.8.2, you have to allow
 re-linking the binary (via supplying object files or dynamic linking),
 because it's LGPL.  If you are using Oniguruma new regex engine, you
 have no such restriction.

 Gabriele Renzi added:
  IIRC 1.9 in the cvs already has oniguruma as the standard regex lib.

Try a System

If you’d like to have a chance to try out an application that uses CMU Sphinx, try the Communicator, an experimental system that helps you plan air travel. You can reach it at the toll-free number 1-877-CMU-PLAN (1-877-268-7526) or at +1 412 268 1084.. The system will provide real flight information. The system may be sensitive to loud background noises, especially over cell phones.

(Source: Paul Graham) I had a front row seat for the Internet Bubble, because I worked at Yahoo during 1998 and 1999. One day, when the stock was trading around $200, I sat down and calculated what I thought the price should be. The answer I got was $12. I went to the next cubicle and told my friend Trevor. "Twelve!" he said. He tried to sound indignant, but he didn’t quite manage it. He knew as well as I did that our valuation was crazy.

Yahoo was a special case. It was not just our price to earnings ratio that was bogus. Half our earnings were too. Not in the Enron way, of course. The finance guys seemed scrupulous about reporting earnings. What made our earnings bogus was that Yahoo was, in effect, the center of a pyramid scheme. Investors looked at Yahoo’s earnings and said to themselves, here is proof that Internet companies can make money. So they invested in new startups that promised to be the next Yahoo. And as soon as these startups got the money, what did they do with it? Buy millions of dollars worth of advertising on Yahoo to promote their brand. Result: a capital investment in a startup this quarter shows up as Yahoo earnings next quarter— stimulating another round of investments in startups.

I especially like this part: Nerds don’t just happen to dress informally. They do it too consistently. Consciously or not, they dress informally as a prophylactic measure against stupidity.

 Whoa, say what?

 Rubydium is aiming to become an optimising reimplementation
 of the Ruby 1.8 interpreter, currently its as good as vapourware
 however the key mechanism has been prototyped, thusly before
 commencing a major rewrite I thought i'd release the
 current state of the art.

This hurts the ruby experience a little bit, because among those characters are {}[]~\| …

and the solution

 Fast Company has a terrific cover piece this month about Jeff Bezos.
 My favorite part is when he talks about asking other people (experts, even)
 for their opinion about new projects.

 Inevitably, people say no. Don't do it. I don't like it. It'll fail.
 Don't bother.

 When I think about every successful project (whether it's a book
 or a business or a website) the people I trust have always given
 me exceedingly bad advice. And more often than not, that advice
 is about being conservative.

 The incentive plan here is pretty clear. If someone dissuades you
 from trying, you can hardly blame them for the failure that doesn't
 happen, right? If, on the other hand, they egg you on and you crash,
 that really puts a crimp in the relationship...

 I think the problem lies in the question. Instead of saying,
 "what do you think?" as in, "what do you think about Amazon
 offering 1,000,000 different titles even though some of them are really
 hard for us to get..." the question ought to be, "how can I make this
 project even MORE remarkable?"

I highly recommend you to read more of Seth Godin´s blog

    Madeleine is a Ruby implementation of Object Prevalence:
    Transparent persistence of business objects using command
    logging and snapshots.

          Hi,

          Just figured it was a good time to release all the good stuff I and
          Stephen Sykes have been preparing in the Madeleine CVS. YAML marshalling
          and snapshot compression should be the highlights for our existing
          users.

          Madeleine 0.7 (July 23, 2004):

         * Broken clock unit test on win32 fixed.
         * AutomaticSnapshotMadeleine detects snapshot format on recovery
         * Snapshot compression with Madeleine::ZMarshal
         * YAML snapshots supported for automatic commands
         * SOAP snapshots supported for automatic commands
         * Read-only methods for automatic commands

        If you're planning to use either YAML or SOAP marshalling, beware that
        there are objects and classes that Ruby's own Marshal can handle but
        these can't. You will have to try for yourself if your application
        works, both to make a snapshot and to read it back, with the marshaller
        you want to use.

                                  cheers
