Programming fundamentals

Everytime a programming exercise or project comes up I hear a lot of
my classmates crying out in horror or dismay. I hear them complain
about how hard is or even that it’s impossible to create. And yet I
see a few of us who don’t care how complicated a project is, we just
know that everyhting is doable. I believe the reason for this is that
others still don’t know what we’ve come to realize, you don’t solve a
problem as a whole, you break it into small pieces, and those small
pieces into smaller pieces, until all you have are just a lot of
small, easy to solve problems.
When you’ve come to that point all you
need then is time. Fact is, There’s no programming project that can’t
be reduced into a series of simple arithmetic, true or false
questions, and the separating and combining of strings. The trick of
course is to be able to see the problems as a combination of smaller
pieces, that’s the skill that separates a coding wizard from a
wannabe.

Take my PusoyDos as an example. I didn’t program it all in one get go,
I did it in pieces. First and foremost problem I had to solve was how
to deal th ecards to the players. Eventually I was able to break it
down into just a randomizing function, a few arithmetics, true or
false question and string combination to create the values of the
cards, and a boolean statement to pass it into the designated players.
And I just went on from there.

Programming is actually simple, if you just look at it the right way.

Awwwww. =D

Of course, Jino’s outlook on programming is completely not my fault,
but I hope other people reading this feel encouraged.

Emacs function of the day: rx

Translate a regular expression REGEXP in sexp form to a regexp string.
See also `rx-to-string’ for how to do such a translation at run-time.

ERC pseudo-AI assisted IRC help

March 1, 2004 - Categories: -Uncategorized
  Hmm. That gives me another nifty ERC idea - if we annotate BBDB records with timezones, we should be able to
          greet people good morning/day/evening appropriately. Plus points for greetings in native languages! ;)
  Now that's just insane, really. 
  *augh*
  laugh too
  sacha: I'm sure you'll have it done by tomorrow ;)
  sachac: that could be nice, yes
  ,there is also an evil place without a name -- it does not have emacs
  Added entry to the term "there"
  ,now
  try:  Acknowledgments NowPlaying PostItNow WikiAcknowledgments WikiNow
  arete: Well, I've been thinking of rule-based matching on privmsgs received, with responses suggested in another
          buffer for easy selection with keysequence or mouse... =)
  sachac: good idea
  hehe yeah, saw you mention it the other day
  just one step away from eliza =P
  arete: I'm just thinking of how to do it nicely so that the matches don't take a terribly long time. I suppose
          match-string is my friend. I can build the regexp at the start, match it constantly, then match again based on
          the match string...
  ,df rx
  rx is a Lisp macro in `rx'.
  (rx REGEXP)
  Translate a regular expression REGEXP in sexp form to a regexp string.
  See also `rx-to-string' for how to do such a translation at run-time.
  The following are valid subforms of regular expressions in sexp
  notation.
  STRING ..[Type ,more]
  arete: ... but of course that means I'll be working as a stateless machine for now. Oh well. Actually, no, the
          functions can keep state on their own; I just won't be able to add new keywords without recompiling the regular
          expression, which shouldn't be too hard.
  sachac: I guess the best way for the greeting is some standard text that gets translated at other ercs
  don't forget to weight the chosen responses so you don't have to look through them all each time the same choices
         come up =)
  sachac: use rx-to-string and a variable...
  myrkraverk: Actually, that will hook into my "hi" thing...
  oh, k, then
  myrkraverk: ERC should not only check which of your pals are online, but also which you haven't greeted yet, and
          people who aren't pals but who have greated you specifically. =)
  I haven't written said "hi" thing yet, though.
  Err.
  Greeted.
  Grrr.
  myrkraverk: Ideally, ERC should compile a list of people to say Hi to, and hi them all on one line, appending a
          generic ", world" at the end or something like that. =)
  myrkraverk: An extension to BBDB could have custom greetings for hi. For example, I greet some people in other
          languages.
  sachac: you have too many ppl to say hi to ;)
  myrkraverk: It's a proof of concept! ;)
  myrkraverk: If you tie that in with the funky timezone thing, that would be, well, pretty funky.
  btw, can erc let me know when someone is online?
  sacha: don't' forget the automated reply to a greeting =)
  myrkraverk: However, the timezone thing could be done without the funky hi thing...
  hmm
  arete: My proposed system wouldn't be entirely automated. It would suggest responses, but it would allow the
          user to actually change them or select a different response from the buffer.
  howdy sachac
  arete: I'm thinking of a circular queue of 5 to 10 (of course, configurable) possible replies.
  zeDek: howdy zeDek
  Well, that's an easy way around it - just echo the greeting... ;)
 * sachac is the resident bot-in-training. ;)
  lol
  sachac: btw, I have a photo now on orkut (like you care :P )
  *chuckle*
  zeDek: did you find time to send me the new color-theme ? :)
  Lukhas, ok wait
  thanks
  arete: I'm interested in this because I stay on a few help channels. My hippie-expansion from BBDB is pretty
          useful for expanding factoids, but (a) I don't want to have to remember what to expand, and (b) I want to be
          able to deal with questions I might not have paid attention to. ;)
 * zeDek was migrating old gnusfr.org and emacsfr.org
  lukhas -> free point fr
  myrkraverk: I'll check that out when I get around to starting up a graphical browser...
  did you find hosting room ?
  sacha: now there is a more productive use of it =)
  I can never remember what keyword fsbot wants
  delYsid: Hmmm, that should be interesting.
  arete: The human still filters the automatic responses, of course. =)
  I use it in chess-ics for a very complicated re (760 chars)
  arete: And automatic responses can be of the form :  already...
  arete: Naturally, if we allow functions and strings as canned responses, then we can even have a state machine.
  yumm, pseudo-AI assisted irc help
  Lukhas,
  arete: Yeah, something like that. 
  Lukhas, done
  arete: Worth hacking on in my spare time, I think.

He has a nice Slashdot-style blog. To do something like this, I would need to define the following behavior:

- remember.el should remember to a single page (or depending on the year)
– remember.el should xref an index entry, not a separate heading
– remember.el should also insert category icons
