| 01:04:40 | FromGitter | <martinium> how would I use the mitems iterator on this for loop: ⏎ ⏎ ```code paste, see link``` [https://gitter.im/nim-lang/Nim?at=5865b2a70730ce693724a52e] |
| 01:05:17 | Araq | no need to use it for JsonNodes, these are refs anyway |
| 01:05:53 | FromGitter | <martinium> is there anyway to iterate through jsonNodes faster than a for in loop? |
| 01:06:17 | Araq | I doubt it |
| 01:06:39 | FromGitter | <martinium> python implementation of this is faster on repeated requests |
| 01:07:28 | Araq | slow stdout? |
| 01:07:46 | Araq | btw you can use echo with multiple args and get rid of the &s |
| 01:08:00 | Araq | you can use 'let' instead of 'var' |
| 01:08:12 | Araq | and put the code in a proc if it isn't already |
| 01:08:17 | FromGitter | <martinium> it is |
| 01:08:28 | FromGitter | <martinium> this is just the for loop part |
| 01:08:40 | Araq | my guess is slow stdout |
| 01:08:51 | FromGitter | <martinium> wonder if let would be any faster |
| 01:08:58 | FromGitter | <martinium> than var since it is immutable |
| 01:09:09 | Araq | not in this case |
| 01:09:47 | FromGitter | <martinium> in this case how would you use echo with multiple arguments |
| 01:10:10 | FromGitter | <martinium> this is a program I converted to Nim for a friend and as a learning process |
| 01:11:51 | FromGitter | <martinium> nim version with no warm up is faster than python by over 4 seconds |
| 01:12:05 | FromGitter | <martinium> repeated requested stay in the 1.5 secs and less range |
| 01:12:36 | FromGitter | <martinium> python does about 4.6 secs for first request with repeated runs at 0.58 - 0.77 |
| 01:13:06 | FromGitter | <martinium> not that this is a performance critical app etc |
| 01:13:53 | Araq | echo "multiple ", "args ", "here" |
| 01:15:03 | FromGitter | <martinium> standard out does seem slow on this mac |
| 01:15:28 | FromGitter | <martinium> if I run it on my ubuntu desktop system it’ll more than like be much faster |
| 01:16:14 | Araq | setBufSize(stdout, ...) or something, can't remember. I don't 'echo' data, I use a database |
| 01:16:45 | FromGitter | <martinium> interesting |
| 01:16:52 | FromGitter | <martinium> you just gave me an idea |
| 01:17:04 | FromGitter | <martinium> write the results to a DB then grab from DB |
| 01:17:17 | FromGitter | <martinium> but then bottleneck will probably be DB speed |
| 01:17:20 | FromGitter | <martinium> I would use postgres |
| 01:28:03 | Araq | good night |
| 01:28:15 | FromGitter | <martinium> good night |

| 02:14:28 | dom96 | Interesting post |
| 02:15:16 | dom96 | Hopefully everyone will agree with me on it: http://forum.nim-lang.org/t/2687/1#16626 |
| 02:23:11 | kulelu88 | in order to write Nim code, do I need to understand how pointers work? |
| 02:23:46 | dom96 | kulelu88: depends what you want to write |
| 02:24:09 | kulelu88 | dom96: well nothing mission-critical |

| 03:04:17 | FromGitter | <vegansk> @kulelu88, you don't need it until you write some system or another low level stuff, integretions with c/c++ libraries, etc. But you can miss some critical moments if you are not familiar with them. It's better to understand how to work with memory even if you write java code :-) |
| 03:06:12 | kulelu88 | FromGitter: vegansk I was looking at Go for web programming and it seems that pointers are central to it, which confused me a bit |
| 03:06:13 | FromGitter | kulelu88, I'm a bot, *bleep, bloop*. I relay messages between here and https://gitter.im/nim-lang/Nim |

| 13:12:57 | dom96 | odc: This should answer your question https://github.com/nim-lang/Nim/issues/1506 |
| 13:13:24 | dom96 | it's fixed now I think |
| 13:16:24 | odc | Thanks! I didn't know nim was using the libc's rand before |
| 13:16:58 | odc | but then, the pull request from BlaXpirit should be closed isn't it ? |
| 13:17:28 | odc | he must be a little mad... |
| 13:19:02 | dom96 | which one? |
| 13:19:33 | odc | https://github.com/nim-lang/Nim/pull/5048 |
| 13:21:04 | odc | not sure why endragor says "current random module is unusable for something beyond a toy project" |
| 13:28:46 | Araq | because you cannot change the impl at runtime nor at compiletime. the old Nim problem. "It's not extensible". |
| 13:29:31 | Araq | personally I find Nim's simple stdlib with the patchFile mechanism superior to most other setups out there |
| 13:32:35 | Araq | patchFile is awesome, too bad not many know about it :-) |
