  2 2013-04-06 02:14:34 <ProfMac> are the boot logs available in the filesystem in openWRT after boot up has finished?
  3 2013-04-06 02:14:52 <muhoo> ProfMac: wrong chan?
  4 2013-04-06 02:15:18 <muhoo> ProfMac: logread is the answer tho :-)
  5 2013-04-06 02:15:52 <ProfMac> thanks.  openWRT is relevant to Avalon development, I had thought.
  6 2013-04-06 02:16:11 <muhoo> ah, good point. they use a MIPS with openwrt as their cpu, i'd forgotten that
  7 2013-04-06 02:16:12 <iwilcox> That'd be more a #bitcoin-mining (or whatever it is) question.
  8 2013-04-06 02:16:27 <ProfMac> aha.  thanks.
  9 2013-04-06 02:16:36 <iwilcox> Might be -miners
 10 2013-04-06 02:17:11 <ProfMac> I should visit #bitcoin-tell.me.where.to.go
 11 2013-04-06 02:17:21 <iwilcox> Heh, yeah, #bitcoin-signpost
 12 2013-04-06 02:17:31 <muhoo> isn't there a list channels function in irssi?
 13 2013-04-06 02:17:48 <muhoo> pipe that to grep bitcoin, maybe

 20 2013-04-06 03:20:31 <user123> anyone awake?
 21 2013-04-06 03:20:46 <phantomcircuit> some people are
 22 2013-04-06 03:20:48 <phantomcircuit> what's up
 23 2013-04-06 03:21:16 <user123> are you familiar with the bloom filtering stuff in the protocol?
 24 2013-04-06 03:21:36 <phantomcircuit> not in the least
 25 2013-04-06 03:21:49 <phantomcircuit> and the people who are im pretty sure are asleep

 64 2013-04-06 05:17:39 <user123> could someone clarify something pls. if i run an SPV node and import an existing private key, will it result in me having to re-download all the block headers in order to collect the transactions relevant to me even though i'm already sync'd?
 65 2013-04-06 05:20:17 <gmaxwell> yes. or at least rebloom filter them. Also, if they provide a way to import a key with a birthdate you might be able to scan less.
 66 2013-04-06 05:31:15 <user123> ok, thanks. By rebloom, do you mean something like if you have part sync'd and then import a key, you can set the filter for the remaining and then you only have to re-download the first blocks?
 67 2013-04-06 05:33:00 <gmaxwell> user123: I don't know if any implementations are smart enough to do that _yet_, in theory they could.
 68 2013-04-06 05:33:11 <Goonie_> bitcoinj doesn't
 69 2013-04-06 05:33:26 <user123> don't worry it's for my own implementation
 70 2013-04-06 05:33:57 <user123> and to understand how the whole thing works
 71 2013-04-06 05:55:34 <mushly> is the "public note" that http://blockchain.info/ supports part of the actual blockchain, or just a tag on their website?
 72 2013-04-06 05:55:56 <gmaxwell> the latter
 73 2013-04-06 05:56:00 <quaz0r> architects and engineers agree
 74 2013-04-06 05:56:05 <quaz0r> the twin towers and building 7 were demolished
 75 2013-04-06 05:56:22 <mushly> gmaxwell: thankyou
 76 2013-04-06 05:56:45 <gmaxwell> quaz0r: what does this have to do with the development of bitcoin software?
 77 2013-04-06 05:57:15 <quaz0r> nothing whatsoever
 78 2013-04-06 05:57:40 <quaz0r> im a terrible irc user
 79 2013-04-06 05:57:44 <gmaxwell> Ah. Okay.
 80 2013-04-06 05:57:58 <quaz0r> agree 100%
 81 2013-04-06 06:24:58 <quaz0r> gmaxwell can bitcoin development help combat tyranny?
 82 2013-04-06 06:58:46 <flyingkiwiguy> quaz0r: only if it destroys central banks
 83 2013-04-06 06:59:14 <quaz0r> flyingkiwi you are 100% spot on there
 84 2013-04-06 07:04:57 <flyingkiwiguy> US miltary budget is half of the US's balance of trade deficit. So esentially the Fed provides paper promises to pay China to supply the US military.
 85 2013-04-06 07:05:12 <quaz0r> END THE FED
 86 2013-04-06 07:05:35 <flyingkiwiguy> OT for #bitcoin-dev...
 87 2013-04-06 07:06:16 <quaz0r> is end the fed really offtopic for bitcoin?
 88 2013-04-06 07:06:48 <gmaxwell> quaz0r: It's offtopic for this channel.
 89 2013-04-06 07:07:15 <quaz0r> good point
 90 2013-04-06 07:12:20 <quaz0r> gmaxwell is there a channel where it is on topic to discuss that the central-banking fiat currency tyranny is responsible for the sad state of this world?
 91 2013-04-06 07:14:53 <alaricsp> Perhaps #bitcoin, quaz0r! Do we have a dedicated bitcoin world economics channel?
 92 2013-04-06 07:15:13 <gmaxwell> #bitcoin-politics perhaps
 93 2013-04-06 07:16:21 <gmaxwell> The network is reallllly close to performing 2^56 SHA256 operations per block now... eat that deepcrack.
 94 2013-04-06 07:17:33 <mushly> heh, if they were DES key attempts, you'd be able to exhaust the entire keyspace in a second
 95 2013-04-06 07:18:30 <gmaxwell> mushly: well, depends on what gear.. software implementations of DES are remarkably slow.
 96 2013-04-06 07:19:04 <mushly> probably wasn't the best example, it was the first thing I could recall that had the same sized keys
 97 2013-04-06 07:20:33 <alaricsp> I suppose it's valid to say that (modulo some constant factor) the effort performed to generate each block is kind of comparable to that of brute-forcing a DES key.
 98 2013-04-06 07:21:01 <alaricsp> Assuming, as most cryptograhic brute-forcing analyses go, that you have a machine that does a DES decryption in a single "tick" :-)
 99 2013-04-06 07:21:31 <gmaxwell> mushly: well that was actually my point in pointing it out.
100 2013-04-06 07:22:20 <gmaxwell> in hardware sha256 is mmmuuuch slower than DES.
101 2013-04-06 07:24:29 <mushly> gmaxwell: this is why you are the developer, and I'm not
102 2013-04-06 07:28:42 <MC-Droid> cool
103 2013-04-06 08:32:55 <jh2o2389> how can I start bitcoind, without the debug IO? I see a "ln -s /dev/null debug.log", but how can I stop bitcoind performing the HD I/O?
104 2013-04-06 08:41:30 <jh2o2389> I just want to start the process in a silent mode. the dev null workaround, or the printscreen alternative still performs kernel syscalls and IO operations, as far I understand.
105 2013-04-06 08:51:24 <cultavix> good morning
106 2013-04-06 08:51:45 <cultavix> anyone do any kind of charting for web dev. using API's from btc exchanges?
107 2013-04-06 08:56:07 <jh2o2389> good morning cultavix
108 2013-04-06 08:56:24 <cultavix> good morning
109 2013-04-06 08:56:39 <cultavix> I am looking to create a central place to look at all of the markets
110 2013-04-06 08:56:42 <cultavix> that I am interested in
111 2013-04-06 08:56:55 <cultavix> need to figure out which charting to use, which APi's to use
112 2013-04-06 08:56:56 <cultavix> etc
113 2013-04-06 08:57:10 <cultavix> I dont know if this is the right place to talk about this
114 2013-04-06 09:03:37 <jh2o2389> you mean something like bitcoinity.org an bitcoincharts.com? I cant tell you or point you to an API. But as far I understand, you will always depend on the API of an market (like mtgox) and a gui api for the graphs.
115 2013-04-06 09:06:02 <jh2o2389> as gmaxwell asked yesterday in #bitcoin, what want you to do/whats your problem? "cenral place" sounds vague to me.
116 2013-04-06 09:08:49 <jh2o2389> I would welcome an aggregated chart of all markets, with all currencys in the web. Maybe you mean this with "central".
117 2013-04-06 09:10:55 <jh2o2389> s/with all/for all/
118 2013-04-06 09:12:32 <cultavix> Yes
119 2013-04-06 09:12:50 <cultavix> https://btc-e.com/api/documentation
120 2013-04-06 09:13:11 <cultavix> https://www.bitstamp.net/api/
121 2013-04-06 09:13:16 <jh2o2389> ACTION nods
122 2013-04-06 09:13:33 <cultavix> and as for charting
123 2013-04-06 09:14:00 <cultavix> jquery seems like it could be a good choice
124 2013-04-06 09:14:57 <cultavix> http://filamentgroup.com/examples/jqueryui-visualize/
125 2013-04-06 09:15:23 <jh2o2389> cultavix: and mtgox api https://en.bitcoin.it/wiki/MtGox/API/HTTP
126 2013-04-06 09:15:24 <cultavix> I'll start off small
127 2013-04-06 09:15:32 <cultavix> Yes, i've got that page open as well
128 2013-04-06 09:15:57 <cultavix> what ill do is just create a graph, for BTC, displaying the prices from those exchanges
129 2013-04-06 09:16:02 <cultavix> and i'll go from there
130 2013-04-06 09:17:06 <Scrat> [14:14] <cultavix> http://filamentgroup.com/examples/jqueryui-visualize/
131 2013-04-06 09:17:08 <Scrat> wont do
132 2013-04-06 09:17:46 <cultavix> what is wrong with it ?
133 2013-04-06 09:17:47 <Scrat> it has no tooltips, it will only display static data
134 2013-04-06 09:17:59 <cultavix> hrm
135 2013-04-06 09:18:25 <cultavix> so I just want to start off by combining the data from 3 exchanges, into one graph
136 2013-04-06 09:18:35 <cultavix> that will update every 1 minute or so
137 2013-04-06 09:18:47 <jh2o2389> cultavix: start importing the data from the the exchanges with the most volume. from the biggest to the smallest. in front to the target to express the "market price", this will increase the efficiency of your programming costs.
138 2013-04-06 09:19:08 <Scrat> well first of all, you have to best this: http://www.bitcoinity.org/markets
139 2013-04-06 09:19:09 <cultavix> so that would be mtgox
140 2013-04-06 09:19:13 <Scrat> this is the most popular
141 2013-04-06 09:19:16 <cultavix> yes, Scrat
142 2013-04-06 09:19:24 <cultavix> that's my role model :)
143 2013-04-06 09:19:34 <cultavix> he's using canvas
144 2013-04-06 09:20:06 <cultavix> http://www.highcharts.com/
145 2013-04-06 09:20:16 <bwen> https://developers.google.com/chart/interactive/docs/gallery/annotatedtimeline
146 2013-04-06 09:21:07 <cultavix> bwen: thanks
147 2013-04-06 09:21:20 <bwen> I havent tested if it can take live updates tho
148 2013-04-06 09:21:27 <bwen> but its javascript
149 2013-04-06 09:21:31 <bwen> so I guess why not
150 2013-04-06 09:21:51 <Scrat> argh, thats flash
151 2013-04-06 09:21:54 <Scrat> kill it with fire
152 2013-04-06 09:22:44 <bwen> thats what google use on their finance charts
153 2013-04-06 09:23:22 <bwen> ohh maybe this one http://www.amcharts.com/stock-chart/stock-events/
154 2013-04-06 09:23:28 <bwen> first time I run into that one
155 2013-04-06 09:24:39 <bwen> meh its not free >_<
156 2013-04-06 09:24:51 <cultavix> https://data.mtgox.com/api/2/BTCUSD/money/ticker
157 2013-04-06 09:24:58 <cultavix> there's my ticker api
158 2013-04-06 09:25:45 <bwen> meh.. long polling, kill it with fire
159 2013-04-06 09:26:16 <Scrat> cultavix: need realtime data
160 2013-04-06 09:26:20 <Scrat> you can use that as a fallback
161 2013-04-06 09:26:27 <Scrat> websocket as the primary
162 2013-04-06 09:28:56 <bwen> well for javascript push I cant think of anything easier than nodejs + socket.io
163 2013-04-06 09:30:27 <cultavix> hrmm
164 2013-04-06 09:31:54 <cultavix> I might give that a try bwen
165 2013-04-06 09:31:58 <Scrat> but really, dont think for a moment that you can slap some charts together and make it work, this is much more involved
166 2013-04-06 09:32:36 <Scrat> there's a reason bitcoinity and mtgoxlive use their own custom canvas
167 2013-04-06 09:32:39 <bwen> yeah mtgox seems to have started with socket.io and then moved to custom websocket
168 2013-04-06 09:32:57 <bwen> I wonder if it is still nodejs behind
169 2013-04-06 09:33:22 <Scrat> bwen: nop, gox uses socket.io
170 2013-04-06 09:33:33 <Scrat> for their website
171 2013-04-06 09:35:12 <Scrat> it's on a different domain
172 2013-04-06 09:35:18 <bwen> I remember wondering how they were doing their livechart about a month ago and seing socket.io on bitcoinity.org
173 2013-04-06 09:35:27 <bwen> and then checking recently and not seing socket.io
174 2013-04-06 09:36:08 <Scrat> can't see any sign of socket.io on bitcoinity
175 2013-04-06 09:36:44 <bwen> not anymore no, thats why I said they moved to raw webscoket or something else
176 2013-04-06 09:37:28 <jh2o2389> interesting. bitcoinity.org received just $15 on the 1comboyNsev2ubWRbPZpxxNhghLfonzuN address
177 2013-04-06 09:37:54 <sivu> donate more
178 2013-04-06 09:38:17 <jh2o2389> sivu: maybe I have?
179 2013-04-06 09:38:31 <bwen> jh2o2389: maybe they change the address regularly
180 2013-04-06 09:38:36 <bwen> I know I would
181 2013-04-06 09:39:19 <jh2o2389> bwen: ah, okay. This makes sense.
182 2013-04-06 09:41:14 <jh2o2389> I need to leave. I wish you all a nice weekend. Buy.
183 2013-04-06 09:41:29 <Scrat> buy
184 2013-04-06 09:41:32 <bwen> cultavix: http://www.humblesoftware.com/finance/index
185 2013-04-06 09:41:58 <jh2o2389> aehm, Bye! I mean.
186 2013-04-06 09:42:03 <jh2o2389> ;)
187 2013-04-06 09:42:25 <bwen> with a canvas this one. looks pretty :)
188 2013-04-06 09:43:35 <cultavix> take care jh2o2389
189 2013-04-06 09:43:50 <cultavix> oh yea
190 2013-04-06 09:43:53 <cultavix> I like that actually
191 2013-04-06 09:44:03 <cultavix> that looks easy enough
192 2013-04-06 09:44:34 <bwen> its when you want live update that could get tricky
193 2013-04-06 09:44:41 <Scrat> yeah, looks static
194 2013-04-06 09:44:57 <cultavix> hrm
195 2013-04-06 09:45:06 <cultavix> dammit
196 2013-04-06 09:45:46 <Scrat> and then there's the problem of drawing orderbook depth
197 2013-04-06 09:46:57 <cultavix> nodejs is taking forever to compile
198 2013-04-06 09:47:23 <Scrat> you're also compiling V8 and openssl
199 2013-04-06 09:47:27 <Scrat> both huge projects
200 2013-04-06 09:48:01 <bwen> I wonder if "Go" does websockets and have a frontend lib...
201 2013-04-06 09:48:57 <Scrat> bwen: why would you need a frontend lib?
202 2013-04-06 09:49:08 <Scrat> and it does websockets, it's in the core (almost)
203 2013-04-06 09:49:10 <bwen> for abstracting websockets
204 2013-04-06 09:49:53 <Scrat> if you abstract you end with an abomination like socket.io
205 2013-04-06 09:50:03 <bwen> usually when there is a pre-made lib that abstract websockets client/server they usually do both sides as they have their own protocole within the socket
206 2013-04-06 09:50:05 <Scrat> (thanks to IE6/7 for that)
207 2013-04-06 09:50:11 <bwen> like crossbrowser abstraction
208 2013-04-06 09:50:11 <Scrat> websocket spec has been stable for a while
209 2013-04-06 09:50:45 <bwen> I have not bothered with playing with raw websockets yet
210 2013-04-06 09:50:54 <bwen> its on my todo list xD
211 2013-04-06 09:51:54 <Scrat> it's where things are moving, people without a browser that has RFC 6455 websocket support have no business being on the internet really
212 2013-04-06 09:52:03 <bwen> I should start playing with Go, I hear good things from my co-workers. How more and more serious enterprises are starting it implement it
213 2013-04-06 09:52:47 <Scrat> bwen: shhhh, TD is here
214 2013-04-06 09:52:57 <TD> ACTION chuckles
215 2013-04-06 09:53:12 <TD> not for long. i have many things to do today
216 2013-04-06 09:53:37 <bwen> Scrat: so basicly you are saying support just the websocket standard and avoid blotted libraries. Which makes alot of sense :)
217 2013-04-06 09:54:26 <bwen> for self projects. but when you want something professional... you gonna have pressure to get it to work everywhere
218 2013-04-06 09:54:44 <Scrat> bwen: yeah we're not there yet
219 2013-04-06 09:55:26 <bwen> but getting closer :D
220 2013-04-06 09:55:35 <bwen> soon...??_??
221 2013-04-06 09:56:12 <Scrat> for a simple ticker without state you should be able to hack together a websocket client with ajax fallback pretty quickly
222 2013-04-06 09:56:47 <Scrat> in less than 100 lines, without loading a 43 kb (minified mind you) library
223 2013-04-06 09:57:15 <bwen> oooouuuuuuu 43kb lib... help me i'M drowning
224 2013-04-06 09:57:18 <bwen> :P
225 2013-04-06 09:58:16 <bwen> and thats just for the first load because its being cashed
226 2013-04-06 09:58:21 <bwen> oups
227 2013-04-06 09:58:23 <bwen> cached
228 2013-04-06 09:59:07 <Scrat> i dont like bloat
229 2013-04-06 09:59:12 <bwen> I understand the argument, its been made over and over...
230 2013-04-06 09:59:21 <Scrat> socket.io's polling fallbacks are very bloated
231 2013-04-06 09:59:24 <bwen> oh I understand
232 2013-04-06 09:59:34 <bwen> its not the size of the lib that matters
233 2013-04-06 09:59:36 <Scrat> (in the server side)
234 2013-04-06 09:59:37 <bwen> its what they do
235 2013-04-06 09:59:43 <Scrat> but this is all OT, lets stop :p
236 2013-04-06 09:59:50 <bwen> but but :(
237 2013-04-06 10:03:21 <bwen> so why did bitcoin chose freenode as official irc?
238 2013-04-06 10:03:45 <bwen> ACTION *cough cough* TOR *cough*
239 2013-04-06 10:03:47 <cultavix> becase its a free node
240 2013-04-06 10:03:55 <cultavix> lol
241 2013-04-06 10:07:09 <skinnkavaj> Anyone wanna buy a pizza for me with credit card?
242 2013-04-06 10:07:18 <skinnkavaj> Oops wrong channel...
243 2013-04-06 10:11:01 <wumpus> bwen: because nearly all open source projects are here
244 2013-04-06 10:12:47 <rwf> anyone heard of or working on a btc based system similar to bandcamp etc?
245 2013-04-06 10:17:29 <Joric> github pages got attacked recently :) all *.github.com have been moved to *.github.io
246 2013-04-06 10:17:51 <greenstar> china angry at github again?
247 2013-04-06 10:17:58 <Joric> yeah and there was no ssl support in the first place
248 2013-04-06 10:19:21 <Joric> custom domains like bitcoin.org were not affected afaik
249 2013-04-06 10:21:33 <Joric> i wonder why china is angry about github ??
250 2013-04-06 10:22:06 <Joric> ah, found it
251 2013-04-06 10:22:49 <Joric> china govt's trying to censor it using a forged ssl cert
252 2013-04-06 10:23:46 <greenstar> because some githubbers are using it to expose those techies that worked on chinas great firewall
253 2013-04-06 10:53:07 <cultavix> hrmm.. its not going to be very easy to create a live graph from  the exchange API
254 2013-04-06 10:53:19 <cultavix> it would be very easy to make a static chart
255 2013-04-06 10:56:25 <iwilcox> cultavix: There are a few dynamic charting thingys out there.
256 2013-04-06 10:56:37 <cultavix> oh yea?
257 2013-04-06 10:56:45 <cultavix> I am looking at a few ways...
258 2013-04-06 10:57:17 <cultavix> the simplest way I can think of is by using google api charting, by just using curl to get the data I need, then use awk to parse it
259 2013-04-06 10:57:24 <cultavix> then input that into google charts
260 2013-04-06 10:57:27 <cultavix> and display it
261 2013-04-06 10:57:32 <cultavix> and do this every 60 seconds
262 2013-04-06 10:57:43 <cultavix> that's the simplest way I can think of to do it
263 2013-04-06 10:57:56 <cultavix> the other way is by trying to use node.js and socket.io to keep a live stream
264 2013-04-06 10:57:58 <cultavix> of data
265 2013-04-06 10:59:26 <bwen> you could do long polling method
266 2013-04-06 10:59:36 <bwen> its just that its not as efficient
267 2013-04-06 10:59:40 <bwen> but it works
268 2013-04-06 11:02:11 <bwen> if you make too many hits on the exchange json though, they might blacklist you
269 2013-04-06 11:03:07 <cultavix> ah really?
270 2013-04-06 11:03:09 <bwen> so if you have 1000 clients looking at your page which does long polling every 5 secondes to that market json (which isnt yours)
271 2013-04-06 11:03:25 <cultavix> well, initially... the page is just for me :)
272 2013-04-06 11:03:28 <cultavix> and maybe a friend or 2
273 2013-04-06 11:03:30 <bwen> oh actualy... that would be the client...
274 2013-04-06 11:03:33 <bwen> hm
275 2013-04-06 11:04:14 <bwen> cultavix: if its just a small project I would not worry too much.. Your initial idea can work
276 2013-04-06 11:04:26 <cultavix> Yea
277 2013-04-06 11:04:38 <cultavix> ill give a it ago, ill come back to you guys
278 2013-04-06 11:04:41 <cultavix> haha
279 2013-04-06 11:04:41 <cultavix> maybe give a demo
280 2013-04-06 11:05:02 <bwen> :)
281 2013-04-06 11:38:42 <bwen> where could I get more information about "signrawtransaction" ? On https://en.bitcoin.it/wiki/Raw_Transactions I see [<privatekey1>,...] what is the ... mean? :P
282 2013-04-06 11:38:55 <bwen> dont tell me source code plz :P
283 2013-04-06 11:39:37 <Belxjander> repeat the same... as many times as you like
284 2013-04-06 11:39:54 <monkeynipples> bwen, its an array of priv keys
285 2013-04-06 11:40:06 <bwen> oh basicly it should be "signtransactions" ?
286 2013-04-06 11:40:54 <bwen> oups I meant "signrawtransactionS"
287 2013-04-06 11:40:55 <bwen> :p
288 2013-04-06 11:41:08 <bwen> aight aight tx
289 2013-04-06 11:41:11 <bwen> thx*
290 2013-04-06 11:41:12 <bwen> :p
291 2013-04-06 11:41:23 <scripting> Whats the latest version of the Berkeley DB bitcoin can compile with?
292 2013-04-06 11:47:22 <DBordello> I am upgrading to 0.8.1.  Did anything change with the getrawtransaction API?
293 2013-04-06 11:48:36 <bwen> DBordello: https://github.com/bitcoin/bitcoin
294 2013-04-06 11:50:39 <bwen> found it :P
295 2013-04-06 11:50:40 <bwen> https://github.com/bitcoin/bitcoin/compare/master...0.8.1
296 2013-04-06 11:51:10 <bwen> the release-notes.txt :P
297 2013-04-06 11:52:34 <diki> Quick question. How does one make a thin client? I.e creating and receiving transactions, but not having the whole chain stored.
298 2013-04-06 11:53:07 <bwen> diki: I'm no expert but I think they query an online service...
299 2013-04-06 11:53:28 <bwen> not for signing transaciton.... I hope :P
300 2013-04-06 11:57:38 <alaricsp> diki: Read the SPV section of The Paper
301 2013-04-06 11:57:44 <alaricsp> diki: And read the source of electrum, it's Python
302 2013-04-06 11:57:58 <CodeShark> DBordello: yes. you'll need to use -txindex to use it on nonwallet transactions
303 2013-04-06 11:57:58 <diki> Can't say I have much experience with Python.
304 2013-04-06 13:09:44 <pjorrit_> python's super easy

322 2013-04-06 13:57:15 <sipa> mushly: with 170 peers, i know use 366 MiB; it used to be over 800
323 2013-04-06 13:57:23 <sipa> *now
324 2013-04-06 13:57:43 <sipa> though it seems there's still some accumulating memory usage (not an actual leak, but just memory usage increasing over time)
325 2013-04-06 13:58:20 <mushly> I might fire up a 512MB VPS and see if it survives
326 2013-04-06 13:59:04 <JWU42> my git skills suck - just recloned it '
327 2013-04-06 13:59:56 <JWU42> 2 months of a free vps so I can't be that upset
328 2013-04-06 14:00:04 <mushly> DigitalOcean, right?
329 2013-04-06 14:00:10 <JWU42> ACTION nods
330 2013-04-06 14:00:23 <JWU42> tried the NL ones first - horrendous
331 2013-04-06 14:00:31 <JWU42> so went back to US
332 2013-04-06 14:00:45 <JWU42> but really wanted to add a EU node - oh well
333 2013-04-06 14:01:17 <mushly> the first node I ever made in the NL zone seems to be fine, but subsequent ones I've used are bad
334 2013-04-06 14:01:44 <JWU42> I just ran the freevps bench -- not very impressive
335 2013-04-06 14:01:57 <JWU42> even the supposed SSD was poor
336 2013-04-06 14:02:53 <JWU42> sipa: 170 peers abnd 366 MiB = awesome!
337 2013-04-06 14:03:11 <mushly> they're great for web scraping though.
338 2013-04-06 14:03:23 <mushly> 15 instances and you can wget the world.
339 2013-04-06 14:03:53 <JWU42> mushly: that is right - you were the one suggesting them
340 2013-04-06 14:03:56 <JWU42> forgot...
341 2013-04-06 14:05:49 <graingert> what is the correct capitalization and plural for bitcoin in the following sentences:
342 2013-04-06 14:05:54 <denisx> sipa: git HEAD is completely compatible with 0.8.1?
343 2013-04-06 14:05:57 <JWU42> tow 0.8.1 nodes -- 43 conns @ 684MB and and 59 @ 584
344 2013-04-06 14:06:01 <graingert> I like the Bitcoin protocol.
345 2013-04-06 14:06:02 <denisx> so I can switch back and forth?
346 2013-04-06 14:06:02 <graingert> I think the Bitcoin-QT client is too slow, I???d rather try other Bitcoin clients.
347 2013-04-06 14:06:02 <graingert> The enormous mansion was worth three whole bitcoins!
348 2013-04-06 14:07:31 <sipa> denisx: yes
349 2013-04-06 14:08:29 <sipa> graingert: Bitcoin when referring to the system/protocol, bitcoin/bitcoins when referring to the currency
350 2013-04-06 14:08:48 <graingert> sipa: I sent mark three bitcoins
351 2013-04-06 14:08:50 <graingert> or
352 2013-04-06 14:08:54 <graingert> I sent mark three bitcoin
353 2013-04-06 14:08:59 <sipa> 'mark' ?
354 2013-04-06 14:09:07 <graingert> Mark*
355 2013-04-06 14:09:20 <graingert> sipa: ^
356 2013-04-06 14:09:40 <sipa> i'd say 3 bitcoins; but perhaps when it's a fractional number like 2.3 i'd use bitcoin
357 2013-04-06 14:09:47 <sipa> what would you use if it were another currency?
358 2013-04-06 14:09:53 <denisx> graingert: like Deutsche Mark? ;)
359 2013-04-06 14:09:55 <graingert> sipa: 3 dollars
360 2013-04-06 14:09:58 <JWU42> sipa: I was confused as last time I built from MASTER it showed "version" : 80000 which I thought was a problem so did checkout v0.8.1 instead...
361 2013-04-06 14:10:03 <graingert> sipa: 1 penny
362 2013-04-06 14:10:08 <graingert> sipa: 1.2 pennies
363 2013-04-06 14:10:23 <graingert> sipa: fractions induce plurality
364 2013-04-06 14:10:33 <sipa> JWU42: right, the version number isn't increased yet; but git head branched off 0.8.0 not off 0.8.1 (even though it has 0.8.1's changes 'backported' to it)
365 2013-04-06 14:10:34 <graingert> sipa: 0.1 bitcoins
366 2013-04-06 14:10:50 <graingert> sipa: ew
367 2013-04-06 14:10:59 <sipa> 0.8.1 was sort of an emergency release
368 2013-04-06 14:11:07 <JWU42> sipa: understood
369 2013-04-06 14:11:27 <JWU42> so I shouldn't fear the version number - OK
370 2013-04-06 14:11:34 <graingert> sipa: any idea how I should cite a paper that gets the term wrong?
371 2013-04-06 14:11:46 <graingert> sipa: I don't want to litter sic all over my paper?
372 2013-04-06 14:12:00 <sipa> JWU42: debug.log lists the exact build at startup
373 2013-04-06 14:12:01 <graingert> this really isn't the place to ask this
374 2013-04-06 14:12:02 <graingert> but hey
375 2013-04-06 14:12:34 <denisx> git HEAD is still without gavins cleanshutdown changes?
376 2013-04-06 14:12:59 <sipa> graingert: "meh", hard to enforce any official notation in a decentralized system... but there's sort of a consensus about Bitcoin the system and bitcoin the currency; about plurals... use your language's normal :)
377 2013-04-06 14:13:04 <sipa> denisx: hmm, which one?
378 2013-04-06 14:13:19 <denisx> sipa: all of them
379 2013-04-06 14:13:29 <denisx> net.cpp: In function 'bool GetMyExternalIP(CNetAddr&)':
380 2013-04-06 14:13:30 <denisx> net.cpp:342: warning: 'pszKeyword' may be used uninitialized in this function
381 2013-04-06 14:13:31 <denisx> net.cpp:341: warning: 'pszGet' may be used uninitialized in this function
382 2013-04-06 14:13:42 <sipa> what compiler is that?
383 2013-04-06 14:13:58 <denisx> old gcc
384 2013-04-06 14:14:29 <sipa> more recent gcc's do better call tracing and notice that isn't a problem, afaik
385 2013-04-06 14:14:40 <denisx> ok
386 2013-04-06 14:14:59 <denisx> freebsds gcc is 4.2 or something
387 2013-04-06 14:15:15 <sipa> denisx: afaik, git head has all of Gavin's recent changes relating to threads/shutdown
388 2013-04-06 14:16:06 <graingert> sipa: I think I'll just have to mention it in the viva
389 2013-04-06 14:16:23 <graingert> sipa: I doubt any of my professors will know, unless I tell them
390 2013-04-06 14:21:45 <denisx> hmm, five connections and already 500MB right after start
391 2013-04-06 14:21:52 <sipa> RES or VIRT?
392 2013-04-06 14:22:00 <denisx> 458RES
393 2013-04-06 14:22:26 <sipa> that seems a lot, but not yet outrageous... let me know how it evolves
394 2013-04-06 14:22:46 <sipa> you don't use -dbcache with some large number?
395 2013-04-06 14:22:55 <denisx> no
396 2013-04-06 14:30:29 <denisx> sipa: looks stable, it is now at 467M RES
397 2013-04-06 14:30:49 <sipa> wait a few days before you say it's stable :
398 2013-04-06 14:32:11 <denisx> uh, it dropped to 379M
399 2013-04-06 14:32:36 <denisx> and again to 323M
400 2013-04-06 14:32:39 <denisx> strange
401 2013-04-06 14:35:09 <skinnkavaj> Apperently we have Skype bitcoin malware
402 2013-04-06 14:35:10 <skinnkavaj> http://storyfic.com/new-bitcoin-skype-malware-spreading-at-2000-clicks-per-hour/
403 2013-04-06 14:40:55 <BlueMatt> lol...bitcoin cpumining trojan...
404 2013-04-06 14:45:56 <pjorrit_> lol
405 2013-04-06 15:08:55 <moarrr> hey any devs around?
406 2013-04-06 15:09:10 <sipa> yes
407 2013-04-06 15:10:09 <moarrr> the first letter of a public address is 1 (or L/N/T/etc depending on alt-coins)
408 2013-04-06 15:10:13 <moarrr> where is this set in the source code?
409 2013-04-06 15:10:27 <sipa> it's not defined directly
410 2013-04-06 15:10:39 <sipa> addresses have a prefix, called the version byte
411 2013-04-06 15:10:45 <moarrr> oh
412 2013-04-06 15:10:53 <moarrr> where is the version byte set?
413 2013-04-06 15:11:04 <sipa> when converting to base58 thus sometimes leads to a consistent prefix character
414 2013-04-06 15:11:13 <sipa> in base58.h, i think
415 2013-04-06 15:13:55 <flyingkiwiguy> TD: is this the sort of traffic you'd like to see tested on testnet3? http://blockexplorer.com/testnet/block/000000003101f521d1ed57cd692c9270cec7e0467980e1486a99782b26d065ca
416 2013-04-06 15:14:42 <flyingkiwiguy> what's missing (other than say > 600 txes)
417 2013-04-06 15:14:58 <moarrr> sipa, I see litecoin uses 48 as the version byte...        PUBKEY_ADDRESS = 48, // Litecoin addresses start with L
418 2013-04-06 15:15:01 <moarrr> what does 48 mean?
419 2013-04-06 15:15:13 <moarrr> (I thought it was the 48th char in base58 but its not)
420 2013-04-06 15:15:47 <chmod755> hello. i guess a few people have a function to send out alerts - does anybody know if this is public and/or where i can find it? i'd like to test something
421 2013-04-06 15:16:28 <flyingkiwiguy> chmod755: I believe it requires Satoshi's / gavinandresen's private signing key
422 2013-04-06 15:16:33 <rhodon> same issue as moarrr
423 2013-04-06 15:16:51 <sipa> moarrr: addresses are binary data, that is encoded in base58
424 2013-04-06 15:17:03 <flyingkiwiguy> I suppose you could compile a testnet bitcoind with your own private key...
425 2013-04-06 15:17:13 <flyingkiwiguy> *in a box
426 2013-04-06 15:17:15 <chmod755> flyingkiwiguy, yep
427 2013-04-06 15:17:17 <sipa> moarrr: 48 neans byte 48 here, i.e. 0x30
428 2013-04-06 15:17:30 <copumpkin> is there a mechanism to address what happens if gavinandresen gets hit by a bus?
429 2013-04-06 15:17:43 <copumpkin> I guess we just roll out a new client with a new pubkey in it
430 2013-04-06 15:17:45 <sipa> copumpkin: theymos has the key too
431 2013-04-06 15:17:50 <copumpkin> ah :)
432 2013-04-06 15:18:01 <chmod755> copumpkin, we'll kill the bus driver
433 2013-04-06 15:18:08 <flyingkiwiguy> so neither of them are allowed within 100m of each other (or a bus)
434 2013-04-06 15:19:13 <chmod755> i think others like sipa and gmaxwell should also have it
435 2013-04-06 15:19:37 <TD> flyingkiwiguy: i guess. there isn't much variety in those transactions though
436 2013-04-06 15:19:42 <rhodon> what is the letter F in base58
437 2013-04-06 15:19:55 <flyingkiwiguy> can you give me some suggestions TD?
438 2013-04-06 15:20:31 <TD> way wider variety of in/out sizes. maybe different kinds of script, etc
439 2013-04-06 15:21:07 <flyingkiwiguy> sizes in terms of # of inputs / outputs?
440 2013-04-06 15:21:30 <flyingkiwiguy> absoloute amounts of BTC shouldn't matter, right?
441 2013-04-06 15:21:39 <flyingkiwiguy> *lute
442 2013-04-06 15:22:59 <TD> yeaj
443 2013-04-06 15:23:04 <TD> yeah
444 2013-04-06 15:46:02 <shawn_fessenden> Looking for btc-qt 0.8.1-b advice re: resource usage. WinXP host severely bogged down 1.5 days after syncing with network. Host becomes practically useless. No help from logs.
445 2013-04-06 15:46:25 <grapevine> restart client?
446 2013-04-06 15:46:33 <shawn_fessenden> Same thing happens.
447 2013-04-06 15:46:36 <sipa> is it synchronized?
448 2013-04-06 15:46:39 <shawn_fessenden> Yes
449 2013-04-06 15:47:01 <sipa> how much memory dobyou have?
450 2013-04-06 15:47:06 <shawn_fessenden> 2G
451 2013-04-06 15:47:24 <shawn_fessenden> btc usage about 178,000K
452 2013-04-06 15:47:24 <sipa> hmm, should be enough
453 2013-04-06 15:47:51 <sipa> is it consuming cpu?
454 2013-04-06 15:48:07 <shawn_fessenden> CPU consumption about 5%, heavy disk going on.
455 2013-04-06 15:48:15 <Scrat> oh the joy of a 11 year old OS
456 2013-04-06 15:48:42 <flyingkiwiguy> fragmented disk?
457 2013-04-06 15:48:53 <sipa> how many connections?
458 2013-04-06 15:48:57 <shawn_fessenden> Freshly defragged (ntfs)
459 2013-04-06 15:49:03 <shawn_fessenden> 8 connections to the network.
460 2013-04-06 15:49:10 <willphase> shawn_fessenden: does it only exhibit this behavior when bitcoin-qt is running?
461 2013-04-06 15:49:29 <sipa> can you put a few pages of debug.log online somewhere?
462 2013-04-06 15:49:32 <shawn_fessenden> Yes. It's def btc-qt doing it, but I have no idea what it's doing.
463 2013-04-06 15:49:41 <shawn_fessenden> Ok, coming up...
464 2013-04-06 15:51:55 <shawn_fessenden> Trying to pastebin now, but like I said it's taking forever to do anything.
465 2013-04-06 15:52:23 <sipa> well shut it down then
466 2013-04-06 15:52:55 <flyingkiwiguy> shawn_fessenden: check out http://technet.microsoft.com/en-gb/sysinternals/bb896645
467 2013-04-06 15:53:26 <shawn_fessenden> debug.log up at http://pastebin.com/C3am88ER (reading suggested link now)
468 2013-04-06 15:53:27 <flyingkiwiguy> is this a new wallet or a wallet that has a lot of tx in it?
469 2013-04-06 15:53:39 <shawn_fessenden> New
470 2013-04-06 15:53:43 <shawn_fessenden> New wallet
471 2013-04-06 15:54:08 <willphase> shawn_fessenden: is it an upgraded blockchain data file from previous version of bitcoin-qt?
472 2013-04-06 15:54:46 <shawn_fessenden> Saved off old blocks & balance, loaded new client & started. Waited for sync and this happened.
473 2013-04-06 15:56:50 <sipa> shawn_fessenden: do these 'getblocks <number> to <hash>' happen often?
474 2013-04-06 15:57:01 <sipa> (that means someone is downloading the chain from you)
475 2013-04-06 15:58:02 <shawn_fessenden> had to shut down the client. It's just getting to the point where the computer won't do anything. It's unwinding now.
476 2013-04-06 15:58:17 <sipa> what hard drive do you have?
477 2013-04-06 15:58:24 <shawn_fessenden> Seems so sipa
478 2013-04-06 15:58:38 <shawn_fessenden> The kind that spins :)
479 2013-04-06 16:01:28 <shawn_fessenden> Anyway... there's no reason this should be happening. I proly need to wipe all trace of it & reinstall / resync. This has never happened before... only when I upgraded to 0.8.1-b
480 2013-04-06 16:02:39 <MC1984_> dr who = deus ex machina
481 2013-04-06 16:07:26 <shawn_fessenden> Yeah I'm gonna nuke/reup. Can't have this thing getting stuck like that.
482 2013-04-06 16:11:03 <MC1984_> thats goibg to br a really paincul thing to say in about ten years
483 2013-04-06 16:21:41 <dino__> A bit off topic, but have a tricky question about blockchain.info wallets.  I have several addresses in my wallet.  They seem to have pre-selected the "main" receiving address for me (the one that generates the QR code, etc.)  Is there a way to change this?  I don't see any related option in the preferences.
484 2013-04-06 16:22:34 <willphase> dino__: there doesn't appear to be any way of changing it except by deleting the key from your wallet then it pickes the second oldest
485 2013-04-06 16:23:05 <dino__> willphase:  Thanks.  That makes sense.  Awkward, but a reasonable work around.
486 2013-04-06 16:28:56 <cultavix> hrmm
487 2013-04-06 16:29:09 <cultavix> pretty sure that I am getting attacks on my network because of bitcoin
488 2013-04-06 16:29:16 <cultavix> looks like you are targetted
489 2013-04-06 16:29:21 <cultavix> for using the btc client
490 2013-04-06 16:31:27 <Guest53479> ??
491 2013-04-06 16:36:57 <JWU42> sipa: up to 28 conns and under 200MB - very nice!
492 2013-04-06 16:39:37 <wumpus> huh I have a testnet wallet that has an output marked as spent that should not be, which causes the balance shown to be 0 even though there is only a transaction coming in. No idea how it ended up this way.
493 2013-04-06 16:40:52 <sipa> wumpus: i'm pretty sure there are potential inconsistencies possible with the current wallet implementatio
494 2013-04-06 16:41:25 <sipa> wumpus: i've been wanting to drop vfSent from CWalletTx, and use CWallet itself to assess whether a particular output is spendable
495 2013-04-06 16:41:57 <wumpus> sipa: agreed, it may be better not to serialize the vfSpent at all
496 2013-04-06 16:42:18 <sipa> not just not serialize it; drop it altogether
