| 13:01 | <@gnolam> | You know, the worst thing about working with named pipes is that you're constantly fighting the urge to pepper your code with "Ceci n'est pas une named pipe" comments. |
| 13:04 | <@RchrdB> | Heh. I can't think of any time when I've used a named pipe outside of a shell script. |
| 13:04 | <@RchrdB> | 99% of the time, working in an actually-nice programming language, I'd use an anonymous pipe pair from pipe(2) instead. |

| 13:47 | <@gnolam> | Is it unusually hairy? |
| 13:48 | < luke> | I'd much prefer a new yacc personally. |
| 13:50 | <@Azash> | gnolam: It certainly was |
| 13:51 | <@Azash> | Unfortunately it wasn't the hair I was looking for |

| 18:24 | <&Derakon> | Bleh. Of course as soon as I add more detailed logging, the exception I'm trying to track stops happening. |

| 18:25 | <@froztbyte> | gnolam: I haven't had that problem |
| 18:25 | <@froztbyte> | gnolam: but now I might |
| 18:28 | <&Derakon> | This is more like a Weeping Angels bug -- it stops happening when you look at it closely. |

| 20:41 | | * Derakon prods Java, uses a Perl script to autogenerate 75 sets of gettter/setter functions. |
| 20:42 | <&Derakon> | Er, getter. |

| 20:42 | < RchrdB> | that in a nutshell is why Java is lameballs |
| 20:42 | <&Derakon> | These functions are, for the moment, just acting as a front-end for a JSONObject that stores arbitrary image metadataâ¦problem being a lot of that metadata isn't arbitrary. |
| 20:42 | <&Derakon> | RchrdB: ehh, I'd have a similar problem with Python in this case. |
| 20:42 | <&Derakon> | It'd be slightly less verbose, but only because of the lack of types and braces. |
| 20:43 | < RchrdB> | er no? You don't ever write "class Foo(object): def getX(self): return self._x; get setX(self, x): self._x = x;" |
| 20:44 | <&Derakon> | Anyway, the plan is to shift at least our own code over to using the getters/setters instead of directly accessing the JSONObject, and then in the next major release version we can remove the non-metadata fields from it altogether. |
| 20:44 | <&Derakon> | RchrdB: depends. Do you want to have the ability to track who's modifying your data by adding a single print statement? |
| 20:44 | <&Derakon> | What if there are side-effects to changing the variable that need to be performed? |
| 20:46 | < RchrdB> | if you do that, you need to step away from Java for a moment, take a deep breath, read https://docs.python.org/2/library/functions.html#property and replace the whole lot with "class Foo(object): def __init__(self): self.x = 'whatever'" |
| 20:47 | <&Derakon> | Ah yeah, I forgot about properties, because I never got around to using new-style classes. |
| 20:47 | < RchrdB> | then, if you need to add side-effects, computation or any such thing to reads or writes to foo.x, you can do so without affecting existing Foo users by swapping it out for a descriptor later. |
| 20:47 | < RchrdB> | what |
| 20:48 | < RchrdB> | new-style classes have been in there since Python 2.2 |
| 20:49 | < RchrdB> | that's 12-13 years ago now |
| 20:49 | < RchrdB> | Derakon, seriously, wtf? Even CentOS 5.x ships Python 2.4! |
| 20:49 | <&Derakon> | Heh. |
| 20:50 | <&Derakon> | Developer inertia, I guess. |
| 20:50 | < RchrdB> | There really is no reason to use old-style classes in Python. Old-style classes even come with a substantial performance dip, IIRC. |
| 20:55 | < RchrdB> | Derakon, http://pastebin.com/fgngUjNp |
| 20:56 | < RchrdB> | Unless you were using multiple inheritance (don't, it's overcomplicated), you may well be able to speed your app up appreciably just by changing "class Foo:" to "class Foo(object):" everywhere. |
| 20:56 | <&Derakon> | RchrdB: no, I can't, because I'm working in Java now instead of Python ;_; |
| 20:57 | <&Derakon> | But I'll keep that in mind for future projects. |
| 20:57 | < RchrdB> | How can you even tell the difference? You were working in a Python dialect in which you had turned off a bunch of useful features by neglecting to read the "what's new in Python2.2" document! |
| 20:57 | < RchrdB> | er |
| 20:57 | < RchrdB> | Sorry, that was overly mean. |
| 20:59 | <&ToxicFrog> | Derakon: my condolences. |
