19:06:06 <instagibbs> hi
19:06:43 <sipa> looks good to me, i'll try to go through those soon
19:06:58 <wumpus> thanks
19:08:19 <wumpus> that's all about this topic, I guess
19:08:27 <wumpus> please help review those ^^
19:08:49 <wumpus> #topic windows 32 bit (MarcoFalke)
19:09:13 <MarcoFalke> There has been at least one user who is running Bitcoin Core on windows 32 bit
19:09:16 <wumpus> #15939
19:09:19 <gribble> https://github.com/bitcoin/bitcoin/issues/15939 | gitian: Remove Windows 32 bit build by MarcoFalke · Pull Request #15939 · bitcoin/bitcoin · GitHub
19:09:36 <MarcoFalke> I didn't expect that initially
19:09:43 <wumpus> I've said what I wanted to say here: https://github.com/bitcoin/bitcoin/pull/15939#issuecomment-489568065
19:09:46 <luke-jr> MarcoFalke: does Windows still support 32-bit only?
19:10:04 <MarcoFalke> Windows 10 can be installed as 32 bit
19:10:42 <luke-jr> on 32-bit only CPUs?
19:10:43 <wumpus> e.g. there's good reason to only support MacOS and Windows on one architecture
19:11:08 <jonasschnelli> Yes
19:11:17 <MarcoFalke> So we ask users to upgrade their windows to 64 bit or buy new hardware?
19:11:24 <jonasschnelli> Also,... do we care about that "one" user?
19:11:30 <wumpus> that there's one windows 32 user left, well, I'm sorry for them :(
19:11:41 <MarcoFalke> A lot might be shy to report
19:12:05 <wumpus> come on, the last x86 hardware that didn't support 64 bit is from 2005 or so?
19:12:33 <wumpus> you can buy a raspberry pi 3 for <$100 and have faster hardware
19:12:55 <wumpus> and 64 bit ARM, at that
19:13:05 <MarcoFalke> Yeah
19:13:10 <wumpus> so, yeah, let's drop it
19:13:14 <booyah> why not support, is it about resources to gitian build?
19:13:19 <MarcoFalke> Enough for this topic
19:13:22 <wumpus> no, read my post
19:13:23 <MarcoFalke> booyah: No, testing
19:13:37 <wumpus> computer resources don't matter
19:13:50 <sipa> in 2011 apparently the last general computing intel cpu that was 32-bit only was introduced (some atom)
19:14:14 <wumpus> yes... so.. next topic
19:14:19 <luke-jr> booyah: the question at the end of the day is, if there's a problem, is anyone willing to deal with it?
19:14:33 <MarcoFalke> [15:04] <kanzure> i have a small topic later about topics
19:14:45 <wumpus> #topic a topic about topics (kanzure)
19:14:47 <achow101> there was at least one complaint about win32 support on bitcointalk.
19:14:49 <ryanofsky> are there 32 bit versions of windows running on 64 bit hardware that can now no longer run bitccoin?
19:15:33 <MarcoFalke> achow101: Link?
19:15:46 <luke-jr> if anyone is willing to support Win32, we should keep supporting it; if not, we can't realistically :p
19:15:54 <meshcollider> Presumably there'd be at least a few out there
19:16:28 <achow101> MarcoFalke: https://bitcointalk.org/index.php?topic=5139689.0 although I'm not sure whether the OP is just wondering why there is no win32 or whether they need win32
19:16:38 <wumpus> so the question is: is anyone willing to test and support windows 32, an debug problems that happen on it?
19:16:39 <ryanofsky> ok just responding to sipa's note about 2011 hardware, wondering if the last 32 bit windows was also released around that time or if it would matter
19:16:58 <wumpus> if no, it doesn't matter that 1 or 2 people are still using it
19:17:05 <luke-jr> I suppose there's a side question of: does testing Win32 identify any general code issues that other tests don't?
19:17:07 <ryanofsky> ok happy to move on
19:17:09 <achow101> ryanofsky: windows still makes 32 bit releases. you can download windows 10 32 bit
19:17:16 <wumpus> yes, let's move on
19:17:19 <wumpus> kanzure: you had a topic?
19:18:10 <wumpus> luke-jr: not more than ARM or Linux x86 32 identifies
19:19:40 <sipa> arguably win64 should catch more things (it's the only 64 bit platform where a 'long' is 32 bits)
19:20:53 <sipa> kanzure: ^
19:21:13 <luke-jr> I think he just wanted to solicit topics for Amsterdam
19:21:35 <MarcoFalke> close meeting?
