01:03:43  <Raynos>whats the most
01:03:45  <Raynos>dead simple way
01:03:49  <Raynos>to replicate leveldb
01:05:37  <ralphtheninja>substack: safe travels
01:06:50  <dominictarr>Raynos, there is an example in the readme, but it's only master slave
01:07:02  <Raynos>really
01:07:02  <dominictarr>it depends on what sort of data you are using.
01:07:24  <dominictarr>you just db.readStream().pipe(db.writeStream())
01:07:28  <Raynos>which readme
01:07:32  <dominictarr>levelup
01:07:43  <Raynos>oh thats copy
01:07:45  <Raynos>not replicate :P
01:08:07  <dominictarr>so, the next most simple way, would be to use a scuttlebutt pattern
01:08:31  <Raynos>replicate to me means synchronizing two ranges
01:08:36  <dominictarr>we could hook that up pretty easy with the stuff I've been working on
01:08:56  <Raynos>what about just sending the entire range
01:08:57  <Raynos>from both ends
01:09:01  <Raynos>and calling merge(a, b)
01:09:02  <Raynos>for each one
01:09:07  <dominictarr>that would work
01:09:17  <Raynos>with an optional handshake up front
01:09:20  <Raynos>to not send entire range
01:09:24  <Raynos>but only different values
01:10:09  <Raynos>stream.pipe(replicate(db, { start, end }).pipe(stream)
01:10:17  <dominictarr>I have an test in map-reduce that writes a update log
01:10:53  <dominictarr>would be cool to use different replication strageties for different key ranges
01:11:24  <Raynos>yeah
01:11:44  <Raynos>replicate(db, { start, end, merge, headshakeStrategy })
01:12:12  <Raynos>maybe also options
01:12:14  <Raynos>to read and write
01:12:17  <Raynos>so you can say
01:12:30  <Raynos>replicate(db, { read }).pipe(replicate(db, { write })
01:12:49  <Raynos>aw man
01:13:02  <Raynos>db.use(function (db) {
01:13:03  <Raynos> db.replicate = function () { ... }
01:13:03  <Raynos>})
01:17:12  <dominictarr>Raynos, the data is a global scope inside the db, with potential collisions, so having separate functions and shit on the outside doesn't help much
01:17:33  <Raynos>seperate functions are clean
01:17:36  <Raynos>because they are functions
01:17:40  <Raynos>and they export one thing
01:18:03  <dominictarr>but they have side effects
01:18:06  <dominictarr>on the database
01:18:08  <Raynos>I prefer the seperate function as a style choice
01:18:12  <dominictarr>so they arn't clean
01:18:36  <Raynos>its less magic
01:18:40  <Raynos>then something monkey patching the db
01:18:42  <dominictarr>this way reflects the underlying nature of the database
01:18:53  <Raynos>its simply cleaner api wise
01:19:20  <Raynos>db.use(replication) db.replicate(...) vs replicate(db, ...)
01:19:25  <Raynos>less bullshi
01:20:19  <dominictarr>if the database had internal closuers, I would do it that way
01:21:29  <dominictarr>you are sticking to a principle too strictly, I'm breaking the rules because I understand their purpose.
01:22:15  * st_lukequit
01:22:56  <Raynos>its not that im stickign too it too strictly
01:23:03  <Raynos>its that im saying one function call is simpler api wise then two
01:23:12  <Raynos>i dont see the benefit to the middleware pattern in this case
01:27:16  <dominictarr>well, nothing is set is stone yet
01:28:35  <ralphtheninja>can I use shoe to connect to a websocket on another site?
01:28:52  * AvianFlujoined
01:29:05  <Raynos>dominictarr: that was a genuine question of why are you breaking the rule. whats the benefit. whats the point
01:29:34  <Raynos>ralphtheninja: yes.
01:30:23  <ralphtheninja>var sock = shoe('www.somesite.com/namespace') ?
01:30:52  <Raynos>yes
01:31:05  <ralphtheninja>eeeexcellent *rubs hands like Mr Burns*
01:31:08  <Raynos>like var sock = shoe("//signalchannel.co/sock")
01:31:38  <dominictarr>Raynos, mainly, because the plugins must mutate the db inside, anyway
01:32:01  <dominictarr>so you need to know if you are, say, already queuing stuff in this database
01:32:18  <Raynos>just patch the db parameter in your function
01:32:19  <dominictarr>so, you should mutate it on the outside too
01:32:47  <dominictarr>you'd need to leave a mark on the db object, so the next time it's called you know what is up
01:32:59  <Raynos>thats fine
01:33:07  <dominictarr>or you'd have to track all these extra queue objects
01:33:07  <Raynos>or you use a weakmap
01:33:10  <dominictarr>and stuff
01:33:27  <dominictarr>weak map won't work in the browser
01:33:40  <Raynos>require("weakmap")
01:33:41  <Raynos>done.
01:33:50  <dominictarr>in the browser?
01:33:56  <Raynos>yes
01:34:05  <Raynos>its has the weakmap garbage semantics
01:34:13  <Raynos>its just not as efficient as a native weakmap
01:34:23  <dominictarr>but does it actually work?
01:34:29  <Raynos>yes.
01:34:32  <dominictarr>okay,
01:34:34  <dominictarr>but anyway,
01:34:35  <Raynos>it may not work on host objects
01:34:51  <Raynos>I agree you have to mutate the db somehow
01:35:05  <dominictarr>you'd also need to use the right objects, like map-reduce uses a queue and some hooks
01:35:23  <dominictarr>so if you tried to add more queues there is the potential of collisions
01:36:14  <dominictarr>you need the queue to know that there is a queue there already, and add to that instead.
01:36:22  <Raynos>oh
01:36:27  <Raynos>so its a shared queue
01:36:32  <Raynos>just between map-reduce
01:36:35  <Raynos>or other modules too?
01:37:05  <Raynos>var queue = map.get(db)
01:37:05  <Raynos>if (!queue) { queue = Queue() map.set(db, queue) }
01:37:30  <Raynos>alternatively
01:37:37  <Raynos>mapreduce = MapReduce(db); mapreduce(...)
01:37:52  <Raynos>now if you had a thing where you wanted to use the same queue
01:37:57  <Raynos>between multiple "leveldb plugins"
01:38:02  <Raynos>then yes .use is the right thing
01:38:18  <Raynos>and you instruct your user to .use(queue).use(mapreduce)
01:40:05  <dominictarr>Raynos, other modules too
01:40:31  <Raynos>how would you co-ordinate it other then tell the user "apply the queue before mapreduce and X"
01:40:40  <Raynos>oh I know
01:40:52  <dominictarr>correct. that is basically how it has to be,
01:40:55  <Raynos>function mapReduce(db) { var queue = require("queue/get")(db) ... }
01:41:04  <Raynos>queue keeps an internal weakmap
01:41:14  <Raynos>and map reduce has dependency on queue and asks queue to fetch a queue for the db
01:41:27  <Raynos>now you dont need to care about it and X can use the same queue module with the same weakmap
01:41:28  * tphummeljoined
01:41:33  <Raynos>except you have npm dedup issues now :/
01:41:39  <Raynos>thats ok
01:41:44  <Raynos>use an Raynos/individual
01:42:10  <Raynos>but thats just as ugly as .use(queue).use(mapReduce)
01:42:11  <dominictarr>I feel like weakmaps are more magic than the way I'm doing it.
01:42:21  <Raynos>except the uglyness is pushed into the implementation
01:42:56  <dominictarr>yes, and I want it to be easy to implement additional plugins
01:43:14  <Raynos>implementing additional plugins is easy. Write functions
01:43:29  <Raynos>if two plugins need access to shared state they should both require the same module and that module should encapsulate shared state
01:43:41  <Raynos>alternatively the user bolts the shared state onto db up front
01:43:43  <Raynos>in the right order
01:44:09  <Raynos>i would prefer the weakmap approach as the user api surface is far cleaner
01:45:31  <dominictarr>can you post an example of how you use weakmaps?
01:45:39  <dominictarr>I'm not really familiar with them

17:51:41  <defunctzombie>substack: for node required, do you really think it is worthwhile to maintain a cache across multiple require calls? It isn't that detrimental to just start afresh for each call to required

18:24:59  <substack>anyways it was a cheap flight so whatevs
18:25:30  <substack>defunctzombie: I think what I actually need is not required() but var r = required(); r.require()
18:26:01  <defunctzombie>substack: why is that?
18:26:15  <substack>defunctzombie: because bundles are composed of multiple files that should all share a cache
18:26:27  <substack>but that cache should only work for the current instance
18:26:48  <defunctzombie>so my point was.. why do you care about this cache sharing?
18:26:53  <substack>otherwise compiling multiple bundles in the same process will fuck up and the cache will get stale/inconsistent
18:27:22  <defunctzombie>from the point of view of required, it just tells you what files would be included
18:27:31  <substack>also required uses detective, not deputy
18:27:33  <defunctzombie>how you consume that information is up to you
18:27:37  <substack>just use deputy, which has a caching layer already
18:28:13  <defunctzombie>what is the point of this caching?
18:28:19  <substack>defunctzombie: except that required is already doing the fs.readFile() and I'd like to avoid doing multiple reads for each file
18:28:22  <defunctzombie>I don't see why any of it is necessary
18:28:34  <substack>caching is SO necessary for browserify
18:28:43  <substack>shit gets really slow without aggressive caching
18:28:55  <defunctzombie>how slow?
18:28:57  <substack>because so many files get read
18:29:06  <substack>defunctzombie: 30+ seconds for a big build with jquery
18:29:19  <defunctzombie>what do you consider a big build?
18:29:36  <defunctzombie>30+ seconds? holy shit
18:29:44  <defunctzombie>I would like to reproduce that
18:29:49  <substack>hij1nx: pong
18:30:34  <substack>hij1nx: testling thing sounds excellent!
18:30:54  <defunctzombie>but yes.. I understand the desire to have the source pulled in by required, that would be a good use case for the options
18:31:31  <defunctzombie>do you have an open source project that I can run browserify on and watch it take 30 seconds?
18:39:19  <substack>defunctzombie: just require('jquery-browserify')

18:46:25  <defunctzombie>spinning disk? what is this, the 90's?
18:46:55  <defunctzombie>I bet most of that work is in the ast generation
18:47:11  <substack>possible
18:47:11  <defunctzombie>but I haven't profiled it to verify
18:47:17  <defunctzombie>reading the file should be a joke
18:47:23  <substack>also it would rock if required could give me streaming updates
18:47:45  <defunctzombie>in what sense?
18:47:54  <substack>especially if it's going to inline the source files with the deps
18:48:11  <substack>the way I'm writing browserify v2 is as a readable stream
18:48:25  <fotoverite>Stream all the things
18:48:31  <substack>so you can pipe its output to a bundle() which is just a through stream
18:49:07  <defunctzombie>well, I don't think the ast generation does streaming
18:49:13  <substack>it doesn't need to
18:49:22  <substack>required could just output each file as it reads it
18:49:33  <mbalho>substack: are you gonna be back in time for festivities
18:49:40  <substack>that way all the files don't need to be buffered into memory and the plugins can start processing right away

18:50:15  <substack>it's nov 23 in japan right now
18:50:16  <defunctzombie>the issue that I can see there is that you lose the parent information

18:50:42  <substack>true story: I left japan nov 22 at 15:00

18:52:51  <defunctzombie>substack: I ran a fs.readFileSync on that jquery lib and timed around it, 0ms
18:53:10  <defunctzombie>so I am pretty confident that the reading is not the issue :)
18:53:38  <defunctzombie>even with reading to utf8 that only accounts for 4ms
19:01:00  <defunctzombie>substack: detective does not work with latest esprima
19:04:58  <substack>!
19:05:33  <defunctzombie>substack: I have the fix
19:05:34  <substack>think I got a pull req for this
19:05:41  <defunctzombie>also, if you don't do the range stuff in detective
19:05:46  <defunctzombie>it is way way faster
19:06:01  <defunctzombie>yea, the fix is just to remove the +1 on line 38
19:06:07  <defunctzombie>when you do the slice
19:06:47  <defunctzombie>anyhow.. if you don't do the slice stuff (and subsequently don't pass range: true) then it is much faster
19:07:14  <substack>hooray
19:07:22  <substack>well that's good
19:10:05  <defunctzombie>I gotta run off (Turkey day activities). If you want the source option added just assign an issue to me with that and I will do it tonight. As for the cache, if after the detective changes you still think it is a worthwhile benefit I am not against it
19:10:18  <substack>ok sweet!
19:10:31  <substack>yes I will mill over the detective changes
19:10:39  <substack>I think perhaps a streaming interface would work best too
19:10:48  <substack>to avoid buffering all the files in memory
19:11:03  <substack>and to allow immediate streaming processing
19:11:17  <defunctzombie>that would be challenging with the current use of esprima
19:11:18  <substack>which is especially important for cpu-bound plugins like transpilers
19:11:29  <substack>the file reads don't need to be streaming
19:11:39  <substack>just every fs.readFile, emit a 'data' event
19:11:45  <defunctzombie>as for streaming for required, the major thing to consider is how that translates to the tree data currently in place
19:11:56  <substack>oh true
19:12:10  <substack>I'm basically just reconstructing the cache data structure for browserify
19:12:16  <substack>it works much better to have a flat structure
19:12:26  <substack>so I'm flattening everything
19:12:31  <substack>I'll push my v2 branch
19:12:43  <defunctzombie>I flatten in script, but that happens outside of required
19:12:53  <defunctzombie>once the full information is known to be able to flatten
19:13:09  <substack>but cache is already flattened
19:13:09  <defunctzombie>I mean.. basically we are talking about a map/reduce of sorts :/
19:13:22  <substack>just a key/value with file => ref
19:14:23  <substack>https://github.com/substack/node-browserify/blob/v2.0/index.js#L40
19:14:26  <defunctzombie>yea, which might be why it is possible to get away with just specifying the parent file
19:14:35  <defunctzombie>if a streaming like interface is desired
19:15:13  <substack>oh I have an idea!
19:15:22  <substack>so keep the regular callback api as-is
19:15:25  <substack>but return a stream
19:15:37  <substack>a stream that emits the source files with the dependency data
19:15:42  <substack>the stream is flat, the callback is nested
19:15:46  <defunctzombie>fascinating
19:16:01  <substack>I'll look into this approach
19:16:05  <defunctzombie>var stream = required('/some/file');
19:16:13  <defunctzombie>so if there is no callback it will just do it with the stream
19:16:18  <defunctzombie>yea, I could see this working
19:16:29  * yorickjoined
19:16:29  * yorickquit (Changing host)
19:16:29  * yorickjoined
19:16:30  <substack>well it could return a stream in either case
19:16:30  <defunctzombie>the only thing is that when you emit a source file
19:16:34  <defunctzombie>yes
19:16:49  <defunctzombie>if you emit a source file tho you don't have the dependency data for it yet
19:16:52  <substack>and it can emit the source files so it doesn't need to keep all the source files in memory while compiling
19:17:28  <substack>you don't have the nested dependency data but I'm only converting to the first-order dependencies anyways
19:17:35  <defunctzombie>unless you emit backwards, but then backwards you lose the in memory thing
19:17:52  <substack>https://github.com/substack/node-browserify/blob/v2.0/index.js#L67-L70
19:18:27  <substack>the callback can return the complete graph, the stream events can return the immediate dependencies
19:18:40  <defunctzombie>does that take into account require('a") within two separate modules possibly leading to two separate files?
19:18:55  <defunctzombie>because that can happen
19:19:05  <substack>yes it's keyed on the filename
19:19:06  <substack>not the id
19:19:08  <defunctzombie>k
19:19:36  <substack>oh also if required() returns a stream it could have a method require() to load another file and to use the same cache
19:19:55  <substack>this is important because browserify bundles can have multiple entry points and explit requires
19:20:11  <defunctzombie>sure
19:20:45  <substack>required(file, cb) could just be sugar for `var r = required(); r.require(file, cb); return r`
19:20:58  <defunctzombie>I will think on it as well, one thing I will note is that it may not be all that much of a gain in the end. the amount of information we are talking about loading into memory is very small :)
19:21:00  <substack>in which case you can ignore my cache PR
19:21:35  <substack>I have some gigantic production bundles I can test this against
19:21:42  <defunctzombie>good :)
19:21:52  <defunctzombie>try removing the range: true from detective
19:21:55  <substack>when you use a lot of modules from npm with a lot of dependencies, this stuff can get pretty big
19:21:56  <defunctzombie>and starting from there
19:21:59  <substack>right
19:22:45  <defunctzombie>holding text files in memory is not the real killer here :) but the streaming interface could lead to something interesting
19:23:25  <substack>also at some point I'd like to take a stab at forking esprima to be streaming
19:24:02  <defunctzombie>that sounds more challenging.. cause again, you have the tree like structure
19:24:17  <substack>actually the code is written in such a way that it shouldn't be very complicated
19:24:30  <substack>the get() function to grab the next token is already abstracted out
19:24:37  <substack>it's just sync when it needs to be async for streaming
19:25:32  <defunctzombie>I don't see how it benefits from streaming as it is single file based
19:25:36  <defunctzombie>and all cpu bound
19:26:04  <defunctzombie>there is no IO within esprima iirc

22:11:58  <juliangruber>dominictarr: can you explain further about the levelup leveled interface?
22:13:27  <dominictarr>Raynos, jjjjohnnny says arrive like, 3? (but any time you want really)
22:13:43  <Raynos>I see
22:13:48  <Raynos>well I knind o wont make that :D
22:13:58  <dominictarr>3 - 5 is good
22:14:43  <dominictarr>juliangruber, well, for a range leveled is an async function that returns an array - but levelup returns a stream
22:15:29  <dominictarr>i could go each(db.range, iterator(key, val) {...})({start: ..., end: ...})
22:15:57  <dominictarr>and each could test if the stream returns a stream or not, but otherwise give me the same interface
22:16:04  * shykeschanged nick to zz_shykes
22:17:51  <juliangruber>dominictarr: I've recently been thinking a lot about unifying interfaces for kv stores. It sucks having so many
22:18:23  <dominictarr>yeah, the other difficult place is batch operations
22:18:29  <dominictarr>you have a chaining interface
22:19:06  <dominictarr>but levelup passes an array
22:20:02  <dominictarr>leveldb is a good starting place for kv store. it's the lowest common denomenator of databases.
22:20:08  <juliangruber>perhaps a wrapper lib that lets you use different kv stores through an standardized interface
22:20:32  <dominictarr>it would be easy to polyfill other kv stores to the leveldb api
22:20:45  <dominictarr>or sql stores as well
22:21:10  <dominictarr>(ofcourse, you are ignoring most of the high level features there)
22:21:18  <juliangruber>so the question is, how does the most node style api for leveldb look like
22:21:25  <juliangruber>and i guess that is levelup
22:21:30  <Raynos>juliangruber: levelup has a pretty good api
22:21:38  <juliangruber>except for batches, chaining is better
22:21:41  <dominictarr>but that is pretty much a given for a unified interface
22:21:54  <Raynos>"chaining is better"
22:22:05  <Raynos>juliangruber: chaining is optional sugar a developer should opt into
22:22:07  <dominictarr>it depends on what you are doing
22:22:08  <Raynos>not the core api
22:22:16  <juliangruber>having the method in a field of the array sucks
22:22:23  <dominictarr>we don't need to paint a bike shed!
22:22:24  <juliangruber>or object
22:22:24  <Raynos>i prefer composition over chaining
22:22:29  <juliangruber>{ method : 'put' }
22:23:00  <dominictarr>the array is easier if you are generating the batch programmatically
22:23:20  <dominictarr>chaining looks better in a readme example
22:23:25  <juliangruber>maybe
22:23:58  <juliangruber>require('key-value')({ backend : 'levelup' })
22:24:01  <dominictarr>what does leveled do under the chaining?
22:24:26  <juliangruber>just pass anything it gets to c, not growing anything in js and then pass that to c
22:24:28  <dominictarr>gozala has an interesting approach to generating unified interfaces
22:24:44  <Raynos>yeah i do like method
22:24:54  <Raynos>juliangruber: why do you want a unified key value API
22:25:05  <dominictarr>so each call gets passed to C?
22:25:44  <dominictarr>I want a unified interface so I can build high level features and then have the low level stuff compete on performance
22:25:49  <juliangruber>Raynos: because I want to use one api that can have multiple backends like in-mem or fs
22:26:04  <Raynos>i dont think like that
22:26:10  <Raynos>I just thing "use levelup"
22:26:14  <Raynos>if I want in memory, which I do
22:26:16  <juliangruber>dominictarr: yes, batch.put() goes directly to c
22:26:19  <Raynos>ill build an in memory cache
22:26:37  <dominictarr>we need to get janl in on this conversation, he wants to reimplement leveldb in js
22:27:01  <Raynos>i see
22:27:04  <Raynos>that should be fun
22:27:07  <juliangruber>dominictarr: i thought about that too, that would be very interesting
22:27:44  <dominictarr>juliangruber, for my purposes I want to intercept puts and turn it into batches, to atomically add things like changes logs, or to queue map-reduce work etc
22:27:51  <juliangruber>dominictarr: although every batch.put() call goes to c it's faster then levelup bc levelup also iterates over that array
22:28:21  <dominictarr>your use case is special
22:28:28  <juliangruber>yup
22:28:33  <dominictarr>you really do need max performance
22:28:38  <dominictarr>fuck everything else
22:28:55  <dominictarr>I need features more than performance
22:29:06  <juliangruber>That's why there's almost no js in leveled, nice features should be added by wrappers. It's just the binding
22:29:41  <dominictarr>yeah, I could easily wrap your batch in a thing take an array like levelup has
22:30:22  <dominictarr>but just call the chaining stuff while iterating over the array.
22:30:37  <juliangruber>eventually I think levelup could swap its binding with leveldb and only do the nice js things
22:30:44  <juliangruber>*with leveled
22:31:20  <juliangruber>or I provide a levelup compatible wrapper
22:31:25  <dominictarr>right. there are some places where there are different compromises made
22:31:32  <dominictarr>like the range function
22:31:40  <juliangruber>mhm
22:32:00  <dominictarr>you are right to buffer everything and return it in one go for raw speed
22:32:13  <dominictarr>but there are other cases where it's faster to go slowly
22:32:49  <dominictarr>like if you have to send it over the network, or don't know how much of the range you actually want
22:32:56  <juliangruber>that still can be implemented on top of leveled, like split the range in even chunks and create a stream from that
22:32:57  <dominictarr>you can do that better with streams
22:33:05  <dominictarr>yup
22:33:47  <juliangruber>still the unified interface would be nice...because leveldb needs c and with that come compilation issues etc
22:34:00  <juliangruber>would be nice to provide a js-only backend
22:34:14  <dominictarr>yeah, it would make it easy to get started
22:35:07  <dominictarr>I can imagine some weird cases where it would be desirable to use an SQL backend too (!)
22:35:16  <juliangruber>haha yes! :D
22:35:31  <dominictarr>like cases where external factors are preventing you from accessing local disk
22:35:44  <juliangruber>or redis
22:35:47  <dominictarr>like on PaaS
22:36:16  <dominictarr>the api is pretty simple, we can make reusable tests that spec the api
22:36:39  <dominictarr>and make it a separate module that all the implementations can just run
22:37:11  <juliangruber>like your stream-spec
22:37:36  <dominictarr>yeah, but it will be a much tighter spec
22:37:47  <dominictarr>can include benchmarks too!
22:38:13  <juliangruber>sweet :)
22:38:32  <dominictarr>this is totally the database of the future
22:38:38  <juliangruber>it is
22:38:51  <juliangruber>leveldb directly in node, it's a dream
22:38:57  <juliangruber>have your heared about kdb?
22:38:59  <dominictarr>hey juliangruber are you gonna go/put in a proposal for mountainjs?
22:39:07  <dominictarr>no, what is kdb?
22:39:43  <juliangruber>it's like node, you build network apps and especially databases in it
22:39:55  <juliangruber>it has it's own languages, q and k (which are short!)
22:39:59  <juliangruber>and is super fast
22:40:11  <dominictarr>link?
22:40:17  <juliangruber>http://thesweeheng.wordpress.com/2008/11/30/more-sudoku-solvers-in-k-and-q/
22:40:37  <juliangruber>I've been introduced to the languages with those snippets
22:40:49  <juliangruber>hard to not get your brain on fire
22:41:06  <dominictarr>oh no, it's super terse!
22:41:18  <juliangruber>but also mighty
22:41:22  <juliangruber>i'd never use it
22:41:34  <dominictarr>does it have a module system that could fit into npm?
22:41:42  <juliangruber>there are given functions whose implementation is shorter than the name
22:41:54  <juliangruber>dunno, it's commercial anyway
22:42:32  <juliangruber>for mointainjs: you mean a talk about dbs in javascript?
22:42:55  <juliangruber>but kdb is basically the same direction as node and leveldb and it is used by hugh companies in production
22:43:14  <dominictarr>well anything, I'm gonna submit a proposal, and it's in your neck of the woods!
22:43:43  <juliangruber>yeah cool, me too :)
22:43:59  <juliangruber>would be my first conference talk
22:44:11  <dominictarr>sweet, my talk will be on building high level features on top of leveldb
22:44:23  <dominictarr>as that is what I'm super excited about right now
22:44:34  <dominictarr>you've done meetup talks?
22:44:52  <juliangruber>only university and in-company talks
22:44:58  <juliangruber>but i like giving talks
22:46:03  <dominictarr>cool
22:46:12  <dominictarr>so, who uses kdb?
22:46:24  <dominictarr>it looks interesting
22:47:41  <dominictarr>I'm getting a finance industry vibe from it
22:47:56  <juliangruber>yup
22:48:18  <juliangruber>can't tell you any names but the guy that evaluated it in my company said so
22:50:35  <dominictarr>I have a friend who has been working on an extremely terse language, I'll try to get him to come hangout
22:51:31  * yorickquit (Remote host closed the connection)
22:51:36  <juliangruber>will be cool to meet you :)
22:51:46  * yorickjoined
22:51:46  * yorickquit (Changing host)
22:51:47  * yorickjoined
22:53:46  * nrknjoined
22:55:48  <dominictarr>nrkn, welcomes to #stackvm!
22:56:34  <nrkn>Hola
22:56:59  <ralphtheninja>heya nrkn
22:57:03  <dominictarr>juliangruber, yeah! hopefully my talk is accepted
22:57:35  <dominictarr>so nrkn juliangruber was just telling me about k/q and it reminded me of tersch
22:58:47  <nrkn>Yeah I think I've vaguely come across them before while I was researching it. Main difference is unlike tersche they seek to be useful
22:58:58  <juliangruber>:D
22:59:16  <juliangruber>what's this tersche?
22:59:36  <nrkn>I was playing with a design for a stack based super terse language
23:00:38  <juliangruber>with what motivation?
23:02:01  * tphummeljoined
23:02:03  <dominictarr>nrkn, I thought you wanted tersch to be useful too?
23:02:58  <nrkn>No particular motivation but inspiration was doing some golfing comps
23:03:22  * defunctzombiejoined
23:03:23  * defunctzombiequit (Changing host)
23:03:23  * defunctzombiejoined
23:03:28  <nrkn>Dominic no not initially but I think we did talk once about some things it could be useful for
23:04:00  <nrkn>You know when you get an idea in your head and it just keeps bugging you it was one of those kinda things
23:04:25  * AvianPhonejoined
23:05:45  * tphummelquit (Client Quit)
23:07:46  * defunctzombiequit (Ping timeout: 246 seconds)
23:08:34  <dominictarr>aha, yeah, and it won't go away until you build it
23:09:20  <nrkn>This is the source for an extremely basic roguelike (terminal display, an @ sign for player moving around a single room map with '#' for walls using arrow keys) in tersche:
23:09:21  <nrkn>C#### ####"a# #### #"b# \8#"c## \6##"d # \6# "eabcdeedcba]mmW5xyxySaW}[email protected]'Dxayb}mb[a[ '=?}[email protected] 'D38x`y1-M}40x`y1+M}37`x1-yM}39`x1+yM}[email protected]'DKk}
23:09:42  <ralphtheninja>omg
23:11:09  <juliangruber>w00t
23:11:52  <ralphtheninja>M is movement?
23:12:34  <dominictarr>dose that define the map as well?
23:12:54  <AvianPhone>OH MY GOD I DO NOT UNDERSTAND
23:12:56  <dominictarr>oh, that C### ... is the map
23:13:35  <dominictarr>you need to make this compile to js
23:14:21  <nrkn>With whitespace
23:14:23  <nrkn>https://gist.github.com/f194ce6a7207510400cd
23:14:49  <nrkn>So the map parts are defined in lines 2-6 then assembled in line 8
23:14:53  <dominictarr>whitespace is for wimps
23:15:11  <nrkn>Agreed
23:15:12  <dominictarr>real men write thier code preminified
23:15:26  <ralphtheninja>aah cool "a is assigning to a?
23:15:32  <nrkn>Yeah
23:16:45  <nrkn>And yeah M is a function that handles movement
23:17:02  <nrkn>defined in lines 17022
23:17:07  <nrkn>Oops 17-22
23:17:16  <nrkn>Hey sorry biab gotta do some work :/
23:17:31  <dominictarr>bah!
23:17:34  <dominictarr>work!
23:17:46  <nrkn>Sorry, line 19-22
23:17:50  <nrkn>17 unrelated
23:17:53  <nrkn>Whitespace confusing me
23:18:16  <ralphtheninja>haha
23:18:19  <dominictarr>what defines which args are passed to which which function
23:19:10  <nrkn>}abM
23:19:17  <nrkn>It's all back to front
23:19:21  <dominictarr>ah, that was my guess
23:19:28  <nrkn>M( a, b )
23:19:29  <dominictarr>it means M takes 2 args
23:19:46  <dominictarr>whats }mb[a[ '=?
23:20:06  <dominictarr>is [ a invocation?
23:20:08  <nrkn>TBH I can't remember - I have some design docs somewhere
23:20:41  <nrkn>But hey sorry again I really gotta go back to work - um [ is something to do with creating or accessing arrays
23:20:43  <dominictarr>you just go xyM
23:20:54  <dominictarr>to do m(x,y)
23:20:58  <dominictarr>to do M(x,y)
23:22:27  * fotoveritequit (Quit: fotoverite)
23:23:00  <juliangruber>dominictarr: submitted :)
23:23:47  <dominictarr>what is your topic?
23:24:23  <juliangruber>building databases with node.js or using streams to simplify controlflow at client and server
23:25:24  <juliangruber>that should match the conference's idea of showcasing javascript and different use cases
23:26:44  <ralphtheninja>what conference are you talking about?
23:26:57  <juliangruber>building a daw in javascript would have been cool too but my thing just still is too early
23:27:01  <juliangruber>mountainjs
23:27:28  <ralphtheninja>ok
23:29:00  * ralphtheninjaquit (Quit: Reconnecting)
23:29:01  * ralphthe1injajoined
23:29:14  * AvianPhonequit (Remote host closed the connection)
23:32:52  * yorickquit (Remote host closed the connection)
23:33:53  <juliangruber>woah feels exciting applying for a talk
23:34:37  <juliangruber>dominictarr: have you read that paper about networking named content?
23:35:32  <dominictarr>juliangruber, no. link?
23:35:54  * lyaunzbequit (Ping timeout: 250 seconds)
23:36:50  <juliangruber>http://pages.cs.wisc.edu/~akella/CS838/F09/838-Papers/ccn.pdf
23:37:16  <juliangruber>with that as a npm module you could implement a basic seaport in like 20 loc
23:37:36  <dominictarr>juliangruber, what is a DAW?
23:37:44  <juliangruber>digital audio workstation
23:37:55  <dominictarr>that would be a cool talk
23:38:05  <dominictarr>it's good to make a talk that sounds kinda crazy
23:39:10  <dominictarr>juliangruber, that paper looks interesting
23:39:35  <juliangruber>very
23:41:04  <juliangruber>like without authorities, auto discovery etc
23:45:43  <juliangruber>I'll be off to sleep
23:45:49  <juliangruber>cya guys :)
