1 2015-10-25 00:47:12 <pindarhk> Apologies as off-topic but 'Call For Proposals' for Phase 2 in HK released. Deadline Nov 9 see https://scalingbitcoin.org/hongkong2015/#cfp
 2 2015-10-25 00:47:35 <Luke-Jr> seems plenty on-topic IMO
 3 2015-10-25 01:03:19 <brand0> OT
 4 2015-10-25 03:16:03 <gmaxwell> BlueMatt: do you have a way that you could benchmark different transport protocols between your relay network hubs?  e.g. could you make two connections and just observe which one got the block across first?
 5 2015-10-25 03:25:41 <bitcoin-dev142> JOIN
 6 2015-10-25 03:33:50 <gmaxwell> BlueMatt: if so, I'd highly recommend trying to use airhook between them, http://airhook.ofb.net/  airproxy in this package is a simple proxy that you can run your existing relay network protocol over (native airhook usage would be superior but would require some protocol redesign).  You'll want this patch https://people.xiph.org/~greg/airproxy.patch.gz  which fixes a realloc-misuse bug.
 7 2015-10-25 04:47:31 <BlueMatt> gmaxwell: hmmm....i could try it across one or two links and see what happens
 8 2015-10-25 04:56:39 <gmaxwell> BlueMatt: I expect fancier transport will be a non-trivial improvement but cooking up something new takes effort, trying this would take almost none. :P
 9 2015-10-25 07:12:33 <vbuilderv> hello
10 2015-10-25 07:14:07 <Adeeel> hi
11 2015-10-25 07:17:26 <vbuilderv> is there a pdf or chm format of the bitcoin developper documents?
12 2015-10-25 07:19:38 <Adeeel> no idea boss
13 2015-10-25 07:32:58 <vbuilderv> I tried to make one , but it seems that the Microsoft Word can not find the svg pictures
14 2015-10-25 07:33:41 <sipa> what developper documents are you talking about?
15 2015-10-25 07:34:44 <vbuilderv> Bitcoin Developer Guide
16 2015-10-25 07:38:43 <sipa> link?
17 2015-10-25 07:43:41 <BlueMatt> sipa: I assume he means bitcoin.org
18 2015-10-25 07:44:56 <vbuilderv> https://bitcoin.org/en/developer-guide
19 2015-10-25 07:46:17 <sipa> oh right, sure
20 2015-10-25 07:46:50 <vbuilderv> I tried to make pdf and chm, but Microsoft Word and Microsoft HTML Help Workshop can not find the svg pictures
21 2015-10-25 07:47:48 <sipa> any reason why print to pdf from browser doesn't work?
22 2015-10-25 07:50:12 <vbuilderv> 3Q, I will try to print from browser
23 2015-10-25 10:36:47 <wumpus> source of those is in markdown - it's certainly possible to generate pdf from those
24 2015-10-25 10:37:45 <Diablo-D3> actually
25 2015-10-25 10:37:50 <Diablo-D3> I swear I saw a markdown to pdf generator lately
26 2015-10-25 10:37:54 <Diablo-D3> like, in the past month
27 2015-10-25 13:56:37 <lclc> My REST Python tests fail every 10th time with '66: insufficient priority' (my fee is 1 BTC). The other 9 times it runs just fine. What part of the test envoirement is changing everytime that might cause this problem?
28 2015-10-25 23:01:10 <paulo_> hello
29 2015-10-25 23:01:20 <paulo_> did satoshi code arith_uint256? or is it standard?
30 2015-10-25 23:10:23 <gmaxwell> paulo_: neither.
31 2015-10-25 23:10:58 <gmaxwell> paulo_: the early bitcoin code used openssl bignums.
32 2015-10-25 23:11:23 <paulo_> oh ok.
33 2015-10-25 23:11:42 <paulo_> after UintToArith256(hash), can I do all kinds of arithmetic on it?
34 2015-10-25 23:11:51 <paulo_> like %,/,*,+, etc?
35 2015-10-25 23:12:00 <gmaxwell> which had the unfortunate property of potentially importing behavior from the mostly unreviewable openssl codebase into consensus.
36 2015-10-25 23:12:23 <phantomcircuit> paulo_, check the header for operator definitions
37 2015-10-25 23:12:49 <gmaxwell> paulo_: there is a collection of arithemetic included in the implementation, though only what we need. (and with performance dictated by our needs...)
38 2015-10-25 23:15:21 <paulo_> it's just ==, !=, and >
39 2015-10-25 23:15:28 <paulo_> *<
40 2015-10-25 23:18:46 <gmaxwell> paulo_: thats not so.
41 2015-10-25 23:19:11 <gmaxwell> (there is, for example, multiplication and division)
42 2015-10-25 23:19:53 <BlueMatt> lol, which of the bitcoin-dev moderators accepted the entirely-empty email?
43 2015-10-25 23:20:24 <paulo_> oh, I was looking at the wrong one, uint256.h
44 2015-10-25 23:20:26 <gmaxwell> "contains nothing offensive. accept."
45 2015-10-25 23:20:29 <phantomcircuit> BlueMatt, was wondering that myself
46 2015-10-25 23:20:51 <BlueMatt> gmaxwell: I find the "Yahoo email" signature offensive!
47 2015-10-25 23:21:01 <paulo_> dang, no modulo
48 2015-10-25 23:21:23 <gmaxwell> paulo_: what would you want that for?
49 2015-10-25 23:22:04 <jcorgan> BlueMatt: that was some sort of weird bug in mailman; the request for moderation was never sent
50 2015-10-25 23:22:22 <gmaxwell> or was it just from a user who'd been whitelisted?
51 2015-10-25 23:22:32 <jcorgan> i can't tell, i need rusty to check
52 2015-10-25 23:22:44 <jcorgan> moderators don't have admin access
53 2015-10-25 23:22:46 <gmaxwell> search for moderation messages from that user previously?
54 2015-10-25 23:23:04 <gmaxwell> if none, it wouldn't have already been whitelisted; no?
55 2015-10-25 23:23:31 <jcorgan> i'm certain i had never seen any moderation request from that user, ever
56 2015-10-25 23:23:34 <paulo_> gmaxwell: altcoin, using smooth numbers.
57 2015-10-25 23:23:46 <paulo_> I'd probably be able to write modulo, though.
58 2015-10-25 23:24:39 <paulo_> it's offtopic here, if you're interested, ##altcoin-dev
59 2015-10-25 23:25:22 <gmaxwell> paulo_: you absolutely wouldn't want to use this code in a proof of work check; its naieve and very slow.  (likely you wouldn't want a proof of work using smooth numbers in any case-- but I'm not going to give you free consulting on the crytpgraphic inadvisability of your random scheme. ... it's really rude to waste our time trying to get help to build competing systems, we've already given you a sta
60 2015-10-25 23:25:28 <gmaxwell> ck of free code.)
61 2015-10-25 23:26:03 <paulo_> oh, sorry.
