[01:30:24] <bobbobbins> hey, I'm trying to do a read from a mongo db but I'm getting an error about it not being the master...and i see that I'm supposed to run slaveOk to fix it, but I'd it to affect all connections...is there a way to do that?
[05:16:28] <Alex474> Hi! Looking for help with $addToSet - works not as expected: http://stackoverflow.com/questions/21011773/addtoset-works-like-push
[06:33:40] <Ravenslock> Hi. There are 3 mongo extensions to choose from mongoyii, directmongosuite, yiimongodbsuite. Which one do I use?

[07:50:06] <axprv> hi, is anyone in here willing to assist me in designing a basic schema in exchange for $50?
[08:07:16] <belak> What's the best way to dump a mongo database so it can be copied to another server?
[08:14:37] <kali> belak: mongodump. but you can also copy the db files if you can stop the source server
[08:47:40] <ns5> g.mongo_db.thread.find({'source_ids':source_id}, {'_id':1}) is this equivalent to g.mongo_db.thread.find({'source_ids':source_id})?
[09:54:53] <ns5> threads = db.thread.find({'source_ids':source_id}, {'_id':1}).skip(count).limit(10), this always find all the threads in db, it seems that skip() and limit() are not working, any idea?
[09:58:19] <ns5> ron: I have db.find().skip().limit() in a while loop, but the loop goes forever because it always finds all the threads
[10:02:50] <ns5> ron: > db.thread.find({'source_ids':ObjectId("52cd13cae8bfec03b2ceb385")}).skip(0).limit(10).count()
[10:11:44] <ron> ns5: http://docs.mongodb.org/manual/reference/method/cursor.count/#cursor.count read :)
[11:25:44] <kas84> if I store multiple kinds of elements in a collection multiple times (with a date field)
[11:34:46] <kas84> I want to retrieve all the objects with different id but only the latest (based on date field which is a unix timestamp)
[11:36:10] <kas84> btw the ones with id 2_1_2 are a copy of 2_1_1 so don't take into account ObjectId
[11:45:06] <ppetermann> i've yet to find a problem where i need the aggregation framework, so far map/reduces allways seemed the better solution, but that might just be usecase related
[11:50:41] <Derick> kas84: db.test.aggregate( [ { $sort: { date: -1 } }, { $project: { _id: 1, id: 1, sub: { type: '$type', value: '$value', level: '$level', status: '$status', _id: '$_id' } } }, { $group: { _id: '$id', latest: { $first: '$sub' } } } ] );
[13:03:16] <jalkstal> My mongorc.js file seems to be cached or something. If I remove it it will still be loaded and if I change its contents the changes are not seen.
[13:07:08] <jalkstal> How can I "reset" the shell so that my mongorc.js file configurations are not loaded?
[15:38:07] <MatToufoutu> I am having an issue with my mongo server, it is running and listening on the right port (netstat confirms), but I'm still unable to connect to it (be it using a library or the mongo client), getting a connection timeout
[15:41:31] <MatToufoutu> I remember having had a similar issue on another machine in the past, but can't remember how I solved it, so any help would be greatly appreciated :)
[15:43:44] <Joeskyyy> Are you trying to connect to it remotely? Or on the same machine the mongod is running on?
[15:48:44] <MatToufoutu> err, ok, just let me a few minutes to do it and get the output on that machine (different from the one mongo is running on)
[16:03:11] <Derick> connect(3, {sa_family=AF_INET, sin_port=htons(27017), sin_addr=inet_addr("127.0.0.1")}, 16) = -1 ECONNRESET (Connection reset by peer)
[16:14:11] <MatToufoutu> ok, I'm gonna find who I must kill now, someone did something with my iptables config....
[17:29:08] <Joeskyyy> Er…. I mean you can't really force it to move faster? The balancer is going to do its job in the most efficient manner it can
[18:57:09] <ghostbar> So, If I have an embedded doc, and want to update one of them based on the id. How do I do? db.collection.update({"_id": ObjectId}, {embeddoc: .. ??
[19:00:22] <locojay> hi my disk has a 95% io utilization but mem only 6% utilication. how can i dig why mongo is using that much io
[19:02:24] <ron> ghostbar: http://docs.mongodb.org/manual/reference/method/db.collection.update/#update-specific-fields-in-subdocuments
[19:04:04] <ghostbar> db.user.update({"_id": ObjectId("52ceed2bb76111e596e1d143"), "random._id": "hola"}, {$set: {"random.$": {_id: "hola", "a": "y", "b": "z"} }})
[19:05:08] <jergason> also is there a way to monitor when new things get inserted in to the slow query log? I would love to create a dashboard of some kind to let me know how often we are running slow queries
[19:05:58] <ghostbar> ron: actually I will need the field.$ because is an array of embedded documents
[19:52:04] <jergason> that is the end goal, so i can see if they jump up suddenly on a graph instead of digging through table rows
[20:08:19] <NaN> should I need to start the mongod with --rest to use the simple rest interface, or where do I need to put that --rest line?
[20:16:07] <NaN> cheeser: done, now when I try to restart the service it says FAILED but if I go to the URL the server seems running
[22:10:20] <spec__> hey all. I'm a research scientist at NVIDIA where I work on parallel algorithms. I'm getting interested in data mining or analytics as a research direction. Does anyone want to discuss the concerns that are at the frontier of data science right now, so we have some better idea what to investigate?
[22:11:56] <spec__> I'm looking at frequent itemset mining and classification algorithms specifically, but would like some input from NoSQL users
