<sb0> whitequark, just asking about a typical execution time for, say, ~50 entries in the btreemap
<sb0> not a precise answer
<whitequark> sb0: I'll need to measure that
<whitequark> also, the answer will depend on whether it's a hot or a cold lookup
<whitequark> given that it's mostly chasing pointers across the heap
<whitequark> the search routine
<whitequark> it'll also depend on the exact string keys...
<sb0> whitequark, yeah sure, but I'm just asking about a ballpark empirical number on the artiq boards
<whitequark> sure. I'll measure that. I wanted to look at how it does the search first though, and posted the code here for posterity.

<GitHub> [artiq] whitequark commented on issue #706: I strongly suspect this is how LLVM folds floating point operations; it seems hard to imagine what ARTIQ could get wrong to get such a result. I will investigate why, though. https://github.com/m-labs/artiq/issues/706#issuecomment-293471915
<GitHub> [artiq] whitequark commented on issue #708: Should I wait for you to reduce the crash (or dissect it at all), or do it myself? https://github.com/m-labs/artiq/issues/708#issuecomment-293472023
<GitHub> [artiq] whitequark closed issue #591: run another instcombine+sccp after licm or something like that https://github.com/m-labs/artiq/issues/591

<whitequark> mithro: who still uses google groups? the interface is unusable

<mithro> Running your own mail server is almost impossible these days, so I've given up
rohitksingh_work has quit [Ping timeout: 240 seconds]
<whitequark> mithro: lies.
<whitequark> I'm running my own mail server for many years at this point, and it never gave me any trouble
<mithro> whitequark: Then you are better at it then me
<whitequark> mithro: you can set one up for yourself in like ten minutes
<whitequark> https://github.com/whitequark/server-config, cut down all the parts you don't need (ie most of them)
<whitequark> that will exactly match my config
<mithro> whitequark: And then watch as your email gets marked as spam by the major mail providers and you spend huge amounts of time trying to do a very poor job of filtering incoming spam?
<whitequark> no and no?
<whitequark> spamassassin does an excellent job at filtering incoming spam, and SPF+DKIM at marking your mail as legitimate
<whitequark> actually I don't even have DKIM right now and it's still fine
* whitequark shrugs
<whitequark> all the "can't run your own mail server" complaints are FUD
<sb0> mithro, yes, we're also running on a small email server setup here and it works pretty fine
<sb0> mithro, you work for google right? :)
<mithro> Yes, but I hate groups too - it's one of the few products that seems to get worse the more developer time that gets dedicated too it
<whitequark> few? what about the, what, five IM services google has now?
<whitequark> including the XMPP that was shut down except it never was, presumably because google itself has to federate them across somehow
<mithro> whitequark: Yeah that is another :-(
<whitequark> or google search, which is now completely fucked up because it thinks it knows which query you want better than you
<whitequark> I use verbatim mode always, and it *still* manages to mangle queries sometimes
<whitequark> not to mention the result ranking got worse recently
<whitequark> actually, it got worse enough that I switched to duckduckgo, which is now not really any worse despite not changing much
<whitequark> sb0: wait, m-labs.hk isn't gapps?
<whitequark> well the mail server part
<mithro> whitequark: You comments on Search I disagree with, but I doubt there is any point discussing it as
<mithro> s/ as /./
<mithro> whitequark: do you know of any icestorm compatible FPGAs which have enough + fast enough memory to run or1k with Linux? It seems like that would be a huge long shot
<whitequark> mithro: there are none
<whitequark> the largest iCE40 FPGA barely fits an OR1K that is stripped of even both caches
<whitequark> I'm not sure if you could fit even an SDRAM controller there; maybe, yes
<whitequark> but after that it's essentially full
<whitequark> mithro: also that OR1K ran at like 20MHz (maybe even less, I don't recall)
<mithro> Yeah
<mithro> Just have to keep poking Clifford about the Artix-7 support :-)
