06:04 < trueptolemy38> cdecker: Hi, cdecker, sorry to bother you. I'm not sure if this change is valid: https://github.com/ElementsProject/lightning/pull/3073#discussion_r326102015 , will it break the pylightning library?

14:23 < darosior> Ah but it's not included in the PyPi release yet .. (I thought it would avoid the need to change the requirements)

18:11 < rusty> niftynei: I just implemented a method to compress htlc max/min values into 16 bit fixed-point values... I'm pretty deep in this optimization rabbit hole, SEND HELP!
18:50 <@niftynei> ooo fancy 
18:51 < rusty> niftynei: I'm doing some pretty horrible things with mmap and fixed offsets instead of parsing too....
18:51 < rusty> And hacky allocation-as-array so I can use u32 indices rather than pointers.
18:52 < rusty> It's premature optimization gone wild...
18:53 <@niftynei> i had to look up mmap, this guy's articles are always great https://jameshfisher.com/2017/01/26/mmap/
18:53 <@niftynei> well if i get a shovel in the mail today, you might have it next week but i'm not sure that'll help get you out of that hole
18:53 < rusty> niftynei: in this case, we use to to avoid systemcall (and copy overhead, but that's almost zero with these sizes) for accesses.
18:54 < rusty> YOU SHOULD NEVER USE MMAP of course.  If the file gets truncated, whoops, you segfault.  But we never do that, in fact, and we trust the gossipd, so...
18:54 <@niftynei> hahah
18:55 <@niftynei> fixed offsets seem a lot like a jump table... sort of
18:55 < rusty> niftynei: tempted to use u16 for node indices, in fact, save another 4 bytes per channel;!
18:56 < rusty> https://0bin.net/paste/9O2lYHts5BCboJx6#mjRtrs2h3TWBSqnGhSaXRqRXGlWREC7KpDOokLsEz8A
18:58 <@niftynei> i'm already looking forward to posting these commits to the c-lightning commit twitter
18:58 < rusty> I might just burn the whole thing to the ground in disgust, instead! ;)
