| 15:31.55 | starseeker | yeah, I've seen similar quotes |

| 15:34.41 | starseeker | Java was, as Gosling says in the first Java white paper, designed for average programmers. It's a perfectly legitimate goal to design a language for average programmers. (Or for that matter for small children, like Logo.) But it is also a legitimate, and very different, goal to design a language for good programmers. - Paul Graham |
| 15:35.58 | starseeker | Heh: |
| 15:36.40 | starseeker | Dino Dai Zovi |
| 15:36.50 | starseeker | We all know that Lisp is the best language around, but in the hands of most it becomes like that scene in Fantasia when Mickey Mouse gets the wand. |
| 15:39.29 | archivist | luvely java quote /me steals and adds it to #mysql bot |

| 15:47.10 | ``Erik | oh, and "ratchet&klank" uses a fair chunk of lithp, thuppothedly, as well as that old 'abuse' game |
| 15:47.11 | mafm | what's special about LISP, using lists as main abstraction or modifying other parts of the code on the run, or..? |
| 15:49.07 | ``Erik | meh, lisp has structs, classes, arrays, vectors, ... a zomfg macro system is useful, being able to express things in short clean functions or methods is nice, working in an 'environment' system has huge benefits (like instead of code, compile, load data and test... you just code and test) |
| 15:50.42 | ``Erik | wrote a (obnoxiously simple) gui ide in under 200 lines of scheme a while back, thinks all his copies were on a hdd that cooked, though :( |
| 15:50.46 | mafm | re: travelocity and orbitz... well, you know that there's a surge in COBOL demand because lots of banks use it, right? I don't think that it says anything positive about COBOL though |
| 15:52.18 | brlcad | don't folks have better things to do than pontificate about and navel-gaze on programming languages for hours on end? :-) |
| 15:52.23 | ``Erik | yeah, but simple report generation on a mainframe is far less challenging than multi-facetted path optimization of a constantly changing data set with a slew of concurrent users expecting an interactive experience :D |
