| 15:01 | < catadroid> | Dammit now I'm writing list comprehensions and wishing they were transducers |
| 15:01 | < catadroid> | What have I done to my brain |
| 15:15 | <@Logar> | Replaced it with a small shell script. |
| 15:22 | < catadroid> | ...small ? |
| 15:36 | <@Logar> | You can't fit much more than a fortune cookie text in a shell! |
| 15:38 | | macdjord|slep is now known as macdjord|wurk |
| 16:15 | <@Tarinaky> | catadroid: What's a transducer in thios context? |
| 16:18 | <&ToxicFrog> | Tarinaky: http://clojure.org/reference/transducers |
| 16:26 | <@Tarinaky> | Ah, I wish I was better at FP |
| 16:35 | < catadroid> | Just watch rich Hickey's presentations |
| 16:35 | < catadroid> | You'll pick things up :) |
| 16:38 | <&ToxicFrog> | s/presentations$/\0 and write a bunch of lisp/ |
| 16:38 | <@Tarinaky> | yehno |
| 16:51 | <&ToxicFrog> | Whyever not? |
| 16:58 | <@Tarinaky> | Only a limited number of hours in the day and there's just no money in Lisp. |
| 16:58 | <@Tarinaky> | Being able to do cool FP things in C++ = Big Money though. |
| 16:58 | <@Tarinaky> | That probably makes me the very worst kind of programmer. |
| 17:01 | < catadroid> | Nah |
| 17:01 | < catadroid> | It makes you pragmatic |
| 17:01 | < catadroid> | Fwiw the best move I ever made learning how to write C++ was to pick up some rudimentary Scheme and apply the ideas to my code, though |

| 17:08 | <&ToxicFrog> | ^ |
| 17:09 | <&ToxicFrog> | I pretty much only use C++ and Python at work, but learning other languages has made me a better programmer in general. |
| 17:12 | < catadroid> | Same |
| 17:12 | <@Tarinaky> | You're right. But I'm stretched pretty far thin atm :( |
| 17:13 | < catadroid> | Yeah, it's not mandatory, and I was lucky because I got to learn scheme at uni |
| 17:13 | <@Tarinaky> | "This to will pass" |
| 17:13 | < catadroid> | Also, I'm stupid and do things like read the C++ standard in my spare time so~ |
| 17:31 | <@Tarinaky> | Are you a three star programmer yet? |
| 17:34 | <@Tarinaky> | *snrk* on slap over TCP/IP: "At least they're kind enough to use TCP for the slapping. That means yoiu get to send ACK slaps back." |
| 17:34 | < catadroid> | Yes. |
| 17:34 | < catadroid> | I'm going to verify that, one sec |
| 17:36 | < catadroid> | Ah, nevermind, it's just a reinterpret_cast<void**> |
| 17:37 | | Kindamoody|afk is now known as Kindamoody |
| 17:37 | < catadroid> | (which is because I'm using reflection to traverse an arbitrary tree of data) |
| 17:37 | < catadroid> | (because I'm mad) |
| 17:38 | <@Tarinaky> | Honestly, the most irksome part of that snippet is you're using a void* in C++ |
| 17:38 | <@Tarinaky> | I'm not even sure if that's legal under --pedantic. |
| 17:40 | <@Tarinaky> | I guess it probably is. |
| 17:42 | < catadroid> | It has to be, because the type isn't known until runtime |
| 17:45 | <@Tarinaky> | Isn't this what the Factory pattern is for though? |
| 17:45 | < catadroid> | The code is generic enough to work on types known at runtime on instances known at runtime |
| 17:46 | <@Tarinaky> | Okay. I'll take your word for it, |
| 17:46 | < catadroid> | It's beneficial for that not to be duplicated once per type |
| 17:46 | < catadroid> | Though that's an angle I would consider if the code to generate it was cleverer~ |
| 17:47 | < catadroid> | (but yes, in general it's an awful code smell) |
| 17:48 | <@Tarinaky> | At my last job one of my DLLs passed void* to Ruby. But that was justifyable in that 1) it was C and 2) I was only using them as opaque pointers and not performing any casts on them. |
| 17:48 | <@Tarinaky> | Just using the memory addresses as unique ids. |
| 17:49 | <@Tarinaky> | Well, casting them back in the low-level I guess to pass them back into the thing I was wrapping. |
| 17:49 | <@Tarinaky> | I forget. |
| 17:49 | < catadroid> | Yeah, my rule is that void*s are acceptable at your api edges (where you are immediately casting to a known type) and where you have shared code that's type erased (so the edges of that code essentially save the type info) |
| 17:50 | < catadroid> | This thing I'm talking about is a bit of a grey area but has aspects of both of those things |
| 17:50 | < catadroid> | It's not my favourite piece of code |
| 17:51 | <@Tarinaky> | It was basically ruby functions to getSomeResource():void*, doSomethingWithResource(void*), freeSomeResource(void*) |
| 17:51 | | * catadroid nods |
| 17:52 | < catadroid> | I've seen systems that unnecessarily bypass the C++ type systems (and have to regularly work with one) and those are just pointless headaches |

| 18:32 | <@celticminstrel> | Oh hey, that sounds familiar. :O |
