[00:00:15] <judges119> Joeskyyy: I already am, dawn has broken here in sunny Western Australia. :) Hope your weekend is radical as well.

[01:36:58] <zfaith> hey guys, can you help me debug this problem?

[01:37:08] <zfaith> bson.errors.InvalidDocument: Cannot encode object: set([7200, 'timestamp'])

[02:53:36] <Jestre> Is there an easy way to return only the last doc in a collection? Or do I need to sort by _id -1 and limit 1?

[04:00:30] <cheeser> Jestre: that's it

[05:09:07] <spondbob> any idea about running mongo on raspi?

[06:33:57] <ryansteckler> Hi all. I'm trying to get a list of top 10 users with the best win/loss ratio. I have wins and losses as fields in the documents. I know how to sort and limit. I can't figure out how I would "do the math" to calculate the ratios, and subject that value to the limit and sort, though...

[07:30:03] <goog> Is it easy to scale mongodb?

[07:30:17] <goog> is there a way to autoscale mongo shards and replica sets?

[09:03:49] <ytrezq> Hello, How I can use the active directory for Mongodb users... (this is a web site database; I need to use a framework which only support MongoDB).

[10:55:31] <kkspy[bnc]> Hello! I've got a question. What BSON query format looks like in queries like db.articles.aggregate( [ { $mat.... }, { $gr....}] ); ?

[10:56:06] <kkspy[bnc]> I mean where should I put the array in BSON query document?

[11:01:38] <kali> ?

[17:22:45] <allaire> Hi, I get the following error when I try to restart mongodb using init.d/mongo : /etc/init.d/mongodb: 48: ulimit: Illegal option -u:

[17:22:46] <allaire> any ideas?

[17:22:59] <allaire> line 48 is `ulimit -u 32000`

[17:29:42] <jergason> allaire: what happens when you just try to run that on the command line?

[17:30:20] <allaire> jergason: -bash: ulimit: max user processes: cannot modify limit: Operation not permitted

[17:31:17] <jergason> that is a permission thing, but the -u might not exist in your version of ulimit

[17:31:21] <jergason> try man 2 ulimit

[17:31:28] <jergason> and see if it lists a -u option

[17:31:48] <allaire> ulimit -u 200 works

[17:31:58] <allaire> jergason: pass 200 it does not work

[17:32:15] <jergason> you have a hard limit set somewhere

[17:32:26] <jergason> in /etc/security i think?

[17:32:40] <allaire> I'm on ubuntu 12.04, default AWS image

[17:32:53] <jergason> /etc/security/limits.conf might have a hard limit set

[17:32:59] <jergason> and you can raise it up to that hard limit

[17:33:51] <allaire> jergason: everything is commented

[17:37:30] <allaire> jergason: the restart goes through anyway though

[17:55:21] <allaire> jergason: in the init.d script, when I switch #!/bin/sh to #!/bin/bash, it works

[17:55:29] <jergason> wellllllllllllllllll shooot

[17:56:03] <allaire> what does it means? :P

[18:15:31] <zfaith> guys I'm using mongodb's aggregate function, but the sort doesn't seem to work with pymongo

[18:15:33] <zfaith> anyone have any ideas?

[18:17:11] <Derick> did you use sort as pipeline operator?

[18:17:14] <Derick> please pastebin the code

[18:17:41] <zfaith> http://pastebin.com/zCMj47aJ

[18:18:04] <Derick> that looks fine

[18:18:26] <Derick> but wouldn't you want the sort after the group?

[18:18:49] <zfaith> the output looks like: http://pastebin.com/f1Aebx2a

[18:19:08] <Derick> yes, sort after the group

[18:19:29] <zfaith> ...oh..

[18:19:32] <zfaith> god, I feel dumb.

[18:19:43] <zfaith> thank you :)

[18:20:24] <cheeser> i'm not even sure how that pipeline would work since there appears to be no "time" property in the document.

[18:22:07] <zfaith> its under group

[18:22:18] <zfaith> I wanted to use timestamp, but it gets mangled.

[18:23:45] <cheeser> ha! there it is. and why $sort wasn't working.

[18:24:49] <zfaith> right haha

[22:27:19] <baris> hi

[22:28:09] <baris> I'm trying to decide which way I should got, either I should fetch all the data for a query and make filtering on node or fetch one by one from mongodb

[22:28:16] <baris> which one would be faster or efficient?

[22:28:39] <baris> I feel like former, but could not be sure, since that might cause memory problem to nodejs maybe

[22:42:32] <sharondio> 2 hours fighting with a mongoimport...figures the issue is Microsoft linefeed nonsense.
