There's a book, by a smart guy named Sippser, on compubility theory. It's very easy to read for a theory book, in earnest. Try HopCraft and Ulman if you want a harder read.

You know the language, now know more about languages... why they work and what they can do. It's the reason I stopped posting to node questions... it's all been done before. Unless I can prove that a computer cannot do it or do it in some tractable time, it's easy to do.

Writing an OS, a database, a programming language, all easy. Want me to do it? Sure, I can give you /something/ given enough time, money or man power. What cannot be done or has not been done before is the next step, if you want to keep learning. It includes includes a lot of other semi-practical knowledge: compilers, operating systems, computer architecture, language theory, computibility thoery, data structures etc.. It's nothing you can't learn on the fly. The harder stuff, the real theory stuff and inventing stuff, that's a lifetime road.

But I speak with the slant of an achedemic. I wish I thought of mp3 (storing the audible band), or some of the np-complete proofs (tetris is np-complete), or quantum mechanics. All of this Class::DBI, Rec::Descent stuff, valuable and great, but nothing that hasn't been done before.

Give me strength for today.. I will not talk it away..
Just for a moment.. It will burn through the clouds.. and shine down on me.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
