00:00:07  <gozala>in worst case scenario that will end up head, tail pairs
00:00:19  <gozala>in best it will be just push
00:00:29  <gozala>and there can be everything in between
00:00:36  <gozala>dominictarr: ^
00:01:02  <Raynos>gozala: oh hi
00:01:13  <gozala>Also ideally all the transformation functions don't need to care about any of this
00:01:37  <gozala>which is possible with a help of decorators
00:02:17  <gozala>dominictarr: this basically gives reader control weather it intends to pull
00:02:27  * shamaquit (Remote host closed the connection)
00:02:28  <dominictarr>gozala: yeah -- also, on of my favorite ideas from reducables is how the transforms just pass the pull back to the source
00:02:34  <gozala>or weather it lets input to push on it
00:02:43  <dominictarr>so they don't have to understand what is happening at all
00:02:57  * thl0quit (Ping timeout: 276 seconds)
00:03:09  <Raynos>gozala: I'm on the fence about complexity
00:03:22  <Raynos>I think pull-stream has lower complexity for writing transformations
00:03:30  * Domenic__joined
00:03:35  <Raynos>the only reason to favor your thing
00:03:37  <Raynos>is performance
00:03:43  <gozala>Raynos: is that complex to you
00:03:43  <Raynos>so id need to see some benchmarks
00:03:44  <gozala>var map = pausable(function(f, signal) {
00:03:44  <gozala> return function mapped(next, end) {
00:03:44  <gozala> signal(function(value) {
00:03:44  <gozala> return next(f(value))
00:03:44  <gozala> }, end)
00:03:45  <gozala> }
00:03:45  <gozala>})
00:03:55  <Raynos>having to call pausable
00:03:58  <Raynos>for every single thing
00:04:01  <Raynos>is complex
00:04:12  <Raynos>it stopped being simple functions
00:04:26  <gozala>Raynos: sure if that's too complex
00:04:32  <gozala>than don't do it
00:04:37  <dominictarr>the objective of pull-stream is to make it easy to avoid IO
00:04:38  <gozala>everything comes with a price
00:04:41  <Raynos>anyway the real problem is
00:04:48  <Raynos>how do you pass messages between source & sink
00:04:53  <Raynos>in transformations without fucking it up
00:05:03  <gozala>gist documents that now
00:05:15  <gozala>and that protocol is also extandable
00:05:29  <gozala>in a way that it can degrade to plain pull
00:05:44  <gozala>but input and reader can extend to optimise specific cases
00:05:50  <dominictarr>the preserving backpressure/lazyness across trickier stuff, like concatenating streams that is the hard part.
00:07:23  <gozala>Raynos: also if you don't like pausable you don't have to use them
00:07:25  <gozala>just wriet
00:07:25  <Raynos>gozala: so my genuine opinion on this is thinking hard about the IO use cases and ensuring that backpressure & closing works correctly and cleanly
00:07:26  <gozala>function map(f, signal) {
00:07:26  <gozala> return function mapped(next, end) {
00:07:26  <gozala> function rest(continuation) {
00:07:26  <gozala> return function(signal) {
00:07:26  <gozala> continuation(map(f, signal))
00:07:26  <gozala> }
00:07:27  <gozala> }
00:07:28  <gozala> signal(function(value) {
00:07:28  <gozala> var continuation = next(value)
00:07:29  <gozala> return typeof(continuation) ? rest(continuation) :
00:07:29  <gozala> continuation
00:07:30  <gozala> }, end)
00:07:30  <gozala> }
00:07:37  <Raynos>writing map is easy
00:07:39  <Raynos>writing merge is harder
00:07:45  <Raynos>writing hwm is harder
00:07:49  <Raynos>writing parallel transform is harder
00:07:58  <gozala>Raynos: I've written all of that for reducers
00:08:05  <gozala>take a look at fs-reduce
00:08:26  <Raynos>so my original motivation for pull-stream & recurse-stream
00:08:29  <gozala>Raynos: can you easily cover this case with pull streams
00:08:30  <gozala>https://gist.github.com/Gozala/5314269#stoping-signals
00:08:31  <Raynos>is "fuck streams2.Readable is 700 lines"
00:08:55  <Raynos>from experience I know handling edgecases in streams is fucking hard
00:08:56  <dominictarr>Raynos: +1
00:09:05  <Raynos>so I need to do it and it needs to be correct
00:09:16  <Raynos>it needs to be SO correct that I can rip out all streams from node core and replace them with functions
00:09:25  <Raynos>furthermore it needs to be more performant then node core
00:09:25  <gozala>Raynos: dominictarr I'm not sure how that relates to what I'm trying to do
00:09:35  <gozala>I've being the first one to say node streams suck
00:09:53  <Raynos>gozala: because I can use infinite push signals ( https://github.com/Raynos/signaal ) for non IO stuff and its nice and pure.
00:10:05  <Raynos>gozala: as much as node streams suck they are still incredibly hard
00:10:15  <gozala>Raynos: I'd be very surprised if you can achieve better performance with pull streams
00:10:22  <gozala>than push streams
00:10:29  <Raynos>I've written a ton of stream like things and I dont have the confidence to say that any of them handle backpressure correctly in at least 95% of the cases
00:10:53  <Raynos>gozala: I dont care about pull vs push. I care about pull-stream vs node core. I care about handling backpressure correctly in 100% of the cases
00:11:10  <gozala>Raynos: ok I'm not sure what we're arguing about here
00:11:21  <gozala>so I'll just let you play with pull streams
00:11:43  <dominictarr>gozala: still, very interested to see what you come up with!
00:11:43  <Raynos>im saying that the implementation of a functional push-pull stream that i like depends on can it implement all the real stream things in a simple API
00:11:44  <gozala>and we can back to whiteboard when you realise you need both
00:11:57  <gozala>and so that they can interoperate
00:12:28  <gozala>Raynos: you mix simple and easy a lot
00:12:36  <gozala>idea can be very simple
00:12:37  <Raynos>i dont care that much about the interface / contract as long as it can handle real IO.
00:12:47  <Raynos>gozala: I know I mix simple & easy too much
00:13:06  <gozala>Raynos: have you tried fs-reduce ?
00:13:19  <gozala>did not it handled back pressure properly ?
00:13:19  <Raynos>not yet
00:13:24  <Raynos>Some of the things in there are cool
00:13:44  <gozala>Raynos: also I have to admit that I had to workaround lack of pull
00:13:50  <Raynos>https://github.com/dominictarr?tab=repositories
00:14:03  <Raynos>dominictarr has written like 14 different types of pull based transformation streams
00:14:06  <gozala>by presenting file content stream as concatenation of lazy chunk reads
00:14:11  <Raynos>based on real ways that you want to interact and combine IO operations
00:14:25  <Raynos>I need to catch up on all that work myself
00:15:16  <gozala>dominictarr: Raynos Anyway what I was intended to do is share some of my thought how one can arrange interoperation of push and pull streams
00:15:36  <gozala>not to say you should or should not use them
00:15:41  <Raynos>gozala: I think its an interesting idea. I just need to spend more time to convince myself i need push
00:15:48  <gozala>if you have any feedback I'm curious to hear

01:17:19  <Raynos>dominictarr: https://github.com/dominictarr/hyperscript/pull/5
01:17:48  <Raynos>gozala: I dont think I need push for IO other then you claim its more performant. That's all
01:18:12  <dominictarr>Raynos: does nodeType and nodeName work in IE?
01:18:19  <Raynos>dominictarr: yes
01:18:37  <Raynos>they are DOM1 so pretty old
01:18:39  <gozala>Raynos: with IO usually you don't need push and pull is just fine
01:19:19  <gozala>it's just non trivial to compose apps that need both push streams and pull streams
01:22:45  <dominictarr>Raynos: should your PR be a minor or a patch?
01:22:45  * douglaslassancejoined
01:23:06  <Raynos>dominictarr: data-set is a new feature so minor.
01:23:18  <Raynos>gozala: that's a seperate problem
01:23:26  <dominictarr>was thinking that too
01:25:21  <gozala>Raynos: Indeed it's separate but a problem
01:25:38  <gozala>you can always shoehorn things
01:25:47  <Raynos>gozala: I was thinking about how to implement leveldb with signals
01:25:49  <Raynos>didnt get very far
01:25:55  <gozala>but IMO it's better to design things up front
01:26:16  <Raynos>i think its not unreasonable to reduce scope and create a pull based stream thing purely for node server apps
01:26:24  <Raynos>and deal with stateful push based browser inputs as seperate domain
01:26:43  <gozala>Raynos: I don't think push is browser specific
01:26:53  <gozala>it's problem specific, but not browser specific
01:26:55  <Raynos>give me a good node context where I want push for IO
01:27:21  <gozala>well IRC implementation
01:27:34  <gozala>you need to handle incoming message weather you like it or not
01:27:46  <gozala>it's not up to you weather you wanna handle them or not
01:28:18  <gozala>or any other case where you're up is driven by / reacts to input
01:28:37  <gozala>same with http requests
01:28:50  <gozala>the come in weather you wanna pull or not
01:29:09  <gozala>of course you can keep users waiting until you pull next incoming request
01:29:35  <gozala>but that models problem incorrectly
01:30:31  <gozala>Raynos: ^
01:30:37  <gozala>anyway heading home now
01:30:53  <Raynos>gozala:
01:30:59  <Raynos>but node core currently models sockets as pull
01:31:06  <Raynos>i dont see a problem with it

02:18:56  <defunctzombie>I am pretty happy with internap personally but always on the lookout for options
02:19:21  <st_luke>i think they will set up all the raid stuff if you order it
02:19:38  <st_luke>and im pretty sure you can enable some module in ubersmith to monitor drive status over snmp

02:23:41  <defunctzombie>yea
02:23:42  * wolfeidaujoined
02:23:49  <defunctzombie>and their datacenters are solid
02:23:55  <st_luke>to be honest most hosting companies are really bad with customer private data and security overall
02:24:36  <st_luke>the former voxel stuff that internap is running now is all pretty good, and ubersmith is very secure because the guy in charge of it knows what he's doing
02:24:49  <st_luke>at least the guy in charge of its development
02:25:18  <defunctzombie>that is good
02:25:24  <st_luke>every hosting company ive worked at other than voxel/internap has stored passwords and private customer info in plain text, etc
02:25:30  <defunctzombie>I know that the datacenter is pretty important
02:25:33  <defunctzombie>wow
02:25:43  <defunctzombie>cause there are some major companies operating out of it
02:26:17  <st_luke>a big part of why internap bought voxel was for the datacenters
02:26:22  <st_luke>so they're pretty important to them
02:29:00  <defunctzombie>I would rather pay a premium to have solid shit than go with an unknown name
02:30:33  <st_luke>yeah it cant be that much more anyway
02:30:44  <st_luke>plus you are like a bitcoin millionaire anyway

14:20:04  <marcello3d>dominictarr: once you pin all versions, it becomes a new UI/UX problem of how to update everything/review changes easily
14:20:29  <marcello3d>if you could solve that problem, then people wouldn't mind as much
14:20:54  <dominictarr>marcello3d: yes… what I really need is snapshots of module versions, so that I can see what has changed since the last time I ran the tests
14:21:16  <marcello3d>it's a good argument for just checking in node_modules

14:23:09  * fallsemojoined
14:26:27  <marcello3d>I'm not sure if npm modules should work that way (that recreates the same problem as pinning), but certainly at the app level
14:28:13  <marcello3d>the main problem with pinning is dependencies will get outdated, you start forking projects just to update their package.json

14:33:42  <marcello3d>even exact hash isn't good enough
14:34:01  <marcello3d>they could rewrite their github tree and the hash could disappear (I think?)
14:34:03  <dominictarr>marcello3d: not of one module, but an entrie tree

14:34:31  <marcello3d>hmmm
14:35:05  <marcello3d>that would only work if you shrinkwrapped/archived, right?

14:38:57  <defunctzombie>both of those things matter for a correct and secure deployment
14:39:55  <defunctzombie>and checking into node_modules at the app level doesn't solve the problems of history management
14:40:05  <defunctzombie>it also adds noise to your app repos which is annoying
14:40:08  <dominictarr>yeah, because if some idiot was editing the code in node_module/*/*.js and they published their module and it doesn't work because there is no published modules with their changes because they forgot to update the real dep….

15:43:46  <defunctzombie>dominictarr: meh, so my take on it is that we can build good package managers that don't require that
15:44:05  <defunctzombie>dominictarr: yes, certainly I can always check things in... but I think tooling can be better
15:44:08  <defunctzombie>and not require that
15:44:24  <dominictarr>defunctzombie: yeah, I am leaning that way too
15:44:37  <dominictarr>npm should really be able to be exact about what is installed
15:44:56  <defunctzombie>dominictarr: absolutely
15:45:07  <defunctzombie>dominictarr: otherwise it is useless for dev and prod
15:45:21  <defunctzombie>dominictarr: and I don't buy the argument that a package manager cannot be used to deploy things or such
15:45:26  <dominictarr>you need to be able to know exactly what is installed, and what was last tested
15:45:32  <defunctzombie>yep
15:45:38  <defunctzombie>dominictarr: you are starting to see the light :)
15:45:59  <dominictarr>I'm thinking a hash tree section in the package, or a separate file
15:46:18  <dominictarr>so you can install the old way, and also the last tested version...
15:46:37  <dominictarr>and see what modules are different if they arn't exact

17:48:31  <tmcw>they also work in browserling
17:48:47  <dominictarr>mikolalysenko: that is mostly about where the server is from the client.
17:48:57  <dominictarr>updates are sent immediately
17:49:08  <dominictarr>so, that is about round trip time.
17:49:20  <dominictarr>although, you could look into webrtc
17:49:50  <dominictarr>I think you can get direct connection with that - even over the local network - which will be super fast
17:50:08  <mikolalysenko>dominictarr: but there is going to be some latency due to processing time, etc.
17:50:29  <dominictarr>processing on the server?
17:50:34  <mikolalysenko>yeah
17:50:45  <mikolalysenko>or maybe I am misunderstanding how scuttlebutt works?
17:50:53  * cianomaidinjoined
17:50:57  * cianomaidinquit (Client Quit)
17:51:25  <dominictarr>if two clients are connected to the same server, an update will pretty much bounce off the server and go directly to the other clients
17:51:41  <mikolalysenko>ok
17:52:02  <mikolalysenko>I guess what I am wondering is if scuttlebutt could be used in say a realtime multiplayer game
17:52:31  <mikolalysenko>I would suppose though that you would still need to do some prediction on the client side
17:52:49  <mikolalysenko>but in the game you have values which are usually changing all the time, so many frequent updates get pushed out over the wire
17:53:03  <dominictarr>yes.
17:53:34  <dominictarr>with the basic scuttlebutt/model, consecutive updates overwrite the old values
17:53:52  <dominictarr>so, it doesn't need to send everything
17:54:11  <mikolalysenko>a question about these models: can you create spline models that do stuff like interpolate/predict values?
17:54:32  <mikolalysenko>for example, in most games you want cubic hermite splines to fit position/velocity values
17:55:11  <mikolalysenko>the way it usually works is that clients run some fixed number of ticks behind the server
17:55:21  <mikolalysenko>and the buffer up future positions for objects
17:55:44  <mikolalysenko>then you can basically interpolate each frame to get the position of the object

18:57:09  <isaacs> , play = require('play').Play()
18:57:10  <isaacs>you sure?
18:57:13  <isaacs>cuz that's what i'm getting
18:57:53  <niftylettuce>isaacs: are you doing `$ npm install -g giggity` and then `$ giggity` ? b/c the bin script is weird
18:58:02  <niftylettuce>it should play audio but it doesnt it gives error
18:58:05  <isaacs>niftylettuce: i'm doing `npm install giggity` and then looking at the data
18:58:12  <niftylettuce>yea do the -g flag
18:58:21  <niftylettuce>and then go do head -n12 on the bin file
18:58:24  <isaacs>niftylettuce: yeah, works for m
18:58:26  <isaacs>e
18:58:31  <isaacs>family guy troll
18:58:43  <niftylettuce>isaacs: the audio works for u? wtf i cant repo
18:58:44  <niftylettuce>repro*
18:58:57  <isaacs>niftylettuce: running a second time says the png's corrupted.
18:59:05  <isaacs>niftylettuce: i think the bug is in your code, dude
18:59:32  <niftylettuce>isaacs: no i know of that err, thats not it
18:59:33  <isaacs>oh, it does different ones.
18:59:39  <isaacs>niftylettuce: `npm ls -g giggity`
18:59:50  <niftylettuce>isaacs: now it works, i had a local issue
18:59:51  <isaacs>niftylettuce: whassat do
18:59:54  <niftylettuce>isaacs: :) thanks man <3

22:07:51  <Raynos>isaacs: is there a way we can get rid of `push("")` semantics by just putting the complexity involved in TLS itself?
22:08:18  <isaacs>Raynos: not without having TLS dig into the _readableState
22:08:28  <Raynos>why?
22:08:29  * timoxleyquit (Quit: Computer has gone to sleep.)
22:09:17  <Raynos>As I understand

22:14:35  <defunctzombie>debating about trying 'mon' via 'mongroup' tho but seems more involved
22:15:56  <isaacs>Raynos: no, the point is that we need to NOT call this._read() again right now
22:16:09  <Raynos>then do it in a timeout
22:16:11  <isaacs>Raynos: and you're not suposed to call _read() yoursefl anyway
22:16:12  <Raynos>or something
22:16:14  <isaacs>Raynos: no, that's terrible.
22:16:20  <isaacs>Raynos: think about it, how long do you make the timer for?
22:16:21  <Raynos>that what does pipe do
22:16:25  <Raynos>when you call push("")
22:16:43  <isaacs>Raynos: pipe() sits there waiting for another 'readable' event
22:16:51  <isaacs>which will never come, until you tell it to read some more data.
22:16:51  <Raynos>ok then do that yourself
22:16:55  <isaacs>when?
22:17:01  <Raynos>`this.once("readable", function () { that._read() })`
22:17:09  <isaacs>how do i tell it that i'm not in the 'reading' state?
22:17:13  <isaacs>without putting data into it?
22:17:20  <isaacs>and without signalling failure?
22:17:33  <Raynos>i dont fully understand the state machine
22:17:50  * stlsaintjoined
22:17:51  <Raynos>and so i should just duck out :P
22:17:56  <isaacs>heh :)
22:18:19  <isaacs>in this case, the clear side has no data, and won't have any more data until and unless the encrypted side puts some in.
22:18:27  <isaacs>but you can't know ahead of time when that will be.
22:18:52  <isaacs>and you need to make sure that the Stream machinery knows you're not actively doing anything, so that it will try again later if you call read(0) on it
22:18:54  * timoxleyjoined
22:19:02  <isaacs>it's a very weird case.
22:33:13  * dguttmanquit (Quit: dguttman)
22:33:32  <dominictarr>isaacs: instead of the empty push can't the stream just go ahead and read again on it's own?
22:35:12  <dominictarr>or what if, instead of a push('') you just emitted 'readable' again -- hmm, or is that what push('') does anyway?
22:37:25  <Domeni___>so. this is pretty good. discuss while i commute back home. http://www.dartlang.org/articles/feet-wet-streams/
22:42:06  * Guest71926quit (Ping timeout: 276 seconds)
22:47:02  <isaacs>dominictarr: so, it will go ahead and read() again on its own
22:47:12  <isaacs>dominictarr: but _read() is where the "check if we have more data" logic lives
22:47:15  <jesusabdullah>yo dawgs, question: I have code that's hanging instead of exiting, and I'm closing up everything as far as I can tell. Any protips for figuring out where the extra listener is?
22:47:24  <isaacs>dominictarr: so read() will say, "Oh, I see, I'm already reading. never mind then."
22:47:32  <jesusabdullah>isaacs: you're good at this stuff, any suggestions?
22:47:53  <isaacs>jesusabdullah: var openStuff = process._getActiveHandles()
22:48:01  <isaacs>jesusabdullah: then start poking around on that thing
22:48:07  <dominictarr>right - so calling read twice before the next 'readable' does nothing?
22:48:14  <jesusabdullah>isaacs: also that reminds me, should t.type(xs, 'array') work? It seems to be like, "lolno that is an object" which is TRUE but not what I'm trying to ask
22:48:26  <jesusabdullah>isaacs: t.ok(Array.isArray(xs)) works but, like, :(
22:48:30  <jesusabdullah>isaacs: also thanks
22:50:16  <jesusabdullah>aww crap, it's supertest
22:50:27  <jesusabdullah>I wonder why?
22:50:41  <isaacs>jesusabdullah: t.type(xs, Array)
22:50:56  <jesusabdullah>oh okay
22:51:01  <jesusabdullah>works for me
22:51:20  <isaacs>dominictarr: exactly
22:51:35  <isaacs>dominictarr: that's why i need a way to say "I'm not reading any more, but i'm also not giving youanything, even EOF"
22:52:11  * Domeni___quit (Remote host closed the connection)
22:53:19  <dominictarr>right - I get that, but whats stopping the stream from just getting data - the encrypted stream needs to read more...
22:54:40  <isaacs>yreah
22:55:01  <isaacs>once the crypto side puts more data into openssl, some data MAY become available to the clear stream
22:55:17  <isaacs>so the crypto side says this.opposite.read(0) to say "Hey, buddy, might be some stuff for you"
22:55:42  <isaacs>but from the CryptoStream's point of view, some OTHER object is telling you when that happens, you don't know yourself
22:55:45  <dominictarr>Domenic_: what is the dart module system like? seems like it will have a $classpath (and the associated problems)
22:56:52  <dominictarr>hmm, so can't it just push that into the clear text stream's buffer this.opposite.push(data) ?

23:01:59  * tilgovijoined
23:02:31  <isaacs>dominictarr: well, it doesn't know what to push into the opposite side
23:02:42  <isaacs>dominictarr: the opposite side needs to talk to openssl to get that
23:02:55  <isaacs>dominictarr: it could do this.opposite._read()
23:03:09  <isaacs>dominictarr: but what if it's already *actually* in the middle of reading?

23:08:20  * yorick_joined
23:10:05  * substack_joined
23:12:51  <Raynos>Domenic_: `length` and `isEmpty` semantics sound super dodge
23:13:09  <Raynos>`length` should be a higher order `count :: Stream -> Future<Number>` function
23:13:56  <Raynos>Domenic_: Having `single` and `multiple` as seperate things is going to make for frustrating complexity. reducers has this, it's annoying.
23:14:27  <Raynos>actually wait, I think I'm thinking of having single & multiple semantics for `pull-stream` as well. Maybe it's not a bad idea
23:15:26  <Raynos>`.transform()` and `StreamTransformer` are just pipe and Duplex
23:17:51  <Raynos>Domenic_: The only good thing is an emphasis on functional style stream transformations. The rest is nothing new
23:20:10  <Raynos>Domenic_: the biggest problem I see so far is the lack of backpressure. Also I don't know whether `take(n)` aborts the stream
23:20:53  <Domenic_>Raynos: what's wrong with length and isEmpty.
23:21:14  <Raynos>well does length only fulfill the future when the stream is done?
23:21:15  <Domenic_>Raynos: hmm, good to get implementation experience saying that's bad. It seemed like an elegant way to do pull streams without missing data.
23:21:17  <Raynos>what about isEmpty
23:21:26  <Raynos>when does it fulfill
23:21:29  <Domenic_>yeah that is my understanding
23:21:35  <Raynos>length is ambigious compared to `count`
23:21:42  <Raynos>i dont know what isEmpty will tell me.
23:21:50  <Domenic_>if length === 0
23:22:24  <Domenic_>why do you like count as a function instead of length as a method?
23:28:07  <Raynos>Domenic_: as long as the semantics are the same it's fine.
23:28:20  <Raynos>I just cant tell what `length` and `isEmpty` do and when they do it
23:28:29  <Raynos>I feel that `count` is way less ambigious in what it does
23:30:31  * mikealjoined
23:30:43  <Raynos>Domenic_: Yeah, the lack of references to back pressure or abortion is really bad.
23:31:13  <Domenic_>ah yes, the old back pressure thing
23:33:16  <Domenic_>looks like they have cancel/pause/resume: http://api.dartlang.org/docs/releases/latest/dart_async/StreamSubscription.html
23:35:59  <Raynos>Domenic_: then it's a question whether StreamTransformer bubbles back pressure
23:36:06  <Raynos>and whether where , take, skipWhile & pals bubble it as well
23:36:15  <Domenic_>interesting
23:36:32  * Guest26528joined
23:36:33  * Guest26528changed nick to ITpro
23:36:34  <Raynos>if they dont then there is no back pressure
23:36:53  <Raynos>so I should be able to get a file read and a file write stream
23:37:03  <Raynos>and put a bunch of take / where / bla / transform calls in between
23:37:21  <Raynos>and have the writer write one chunk at a time with manual pause / resume pumping
23:37:26  <Raynos>and the process memory usage should stay flat
23:37:30  <Raynos>no matter how big the files are
23:37:40  <Domenic_>there are no write streams though, not exactly.
23:38:05  <Raynos>Well there are

23:38:54  <Raynos>all the same words
