<azariah> gmaxwell: not sure being gcc targetable really is a big benefit for a smart contract VM. given the cost of blockchain verification of executions, I doubt many would want to directly port existing programs.
<azariah> most use cases of smart contracts require lot's of fluff around the actual contract - GUIs, centralized user handling, etc. offloading only the core consensus critical parts to the smart contract code. for such use cases rewriting a program to a new VM is probably the lesser effort

jtimon has quit [Ping timeout: 272 seconds]
<azariah> the consensus bugs / sec vulns found in the Ethereum VM, both prior to and after it's launch, could be a interesting case study with regards to what is hard to get consensus on in a smart contract VM

<azariah> most of their consensus issues where around VM exceptions & when state transitions affected the life cycle of contracts (contract creation, deletion)

<jgarzik> azariah, It's not about porting existing programs
<jgarzik> azariah, it's about having an existing toolchain ecosystem. You can pick your favorite programming language, and have existing debuggers profilers and more to use.
<jgarzik> The alternative is reinventing all that stuff.. poorly

<jgarzik> kanzure, Did the Big Pile O Ideas ever get archived into a single link, however unsorted?
zooko has joined #bitcoin-wizards
<kanzure> jgarzik: i am having trouble figuring out how to organize the index, struggling with signal/noise theoretical concerns.
<kanzure> jgarzik: advice appreciated
<jgarzik> kanzure, I don't see my IRC idea dump :)
<jgarzik> kanzure, IM chain for example
<kanzure> i have your dump stored somewhere else
<jgarzik> gah! Then it's not a single link. :)
<kanzure> i really do need help figuring out correct format and how to sort signal/noise on this project, otherwise it will just be list of 2000 things and nobody will use it.
<jgarzik> kanzure, I disagree that organization should be a blocker
<kanzure> elaborate plz?
<jgarzik> kanzure, release early, release often. rapidly iterate.
<jgarzik> kanzure, get everything into a single link that is Ctrl-F searchable

<kanzure> now show me the crowd's magic.
<zooko> Could you make it hyperlinkable to subsets? Perhaps by adding an anchor to each line or each section?
<kanzure> i am not convined that a random scratchpad is a good starting point for this

<kanzure> not at the moment, it would be nice if someone else would
<bsm1175321> Your list is overwhelming.
<kanzure> (.mdwn is markdown, theoretically)
<kanzure> yes well jgarzik was pushing me for "release early" so there you go
<bsm1175321> I almost want to write a script to parse it...
<kanzure> for the bookmarks you can just use a yaml parser, http://diyhpl.us/~bryan/irc/bitcoin/bitcoin-selected-bookmarks.2015-09-09.yaml
<kanzure> the yaml format there is used by a bookmarking tool that i'm fond of, https://github.com/davidlazar/jotmuch
<bsm1175321> I see
<kanzure> ((yaml is best analogized as a superset of json))
<bsm1175321> I'm going to sit here and be overwhelmed for a little while longer. But thinking...

<gmaxwell> Does anyone have access to a latest generation amd opteron that they could run the libsecp256k1 benchmarks on?
<nsh> shame no-one implemented ctcp cpuinfo
<nsh> (no, sorry; will ask about)
<gmaxwell> I'm trying to figure out what part yields the greatest _verify per dollar and _verify per part right now. :)
<gmaxwell> maybe I should make a little test collection script that runs the benchmark and submits its result and cpuinfo someplace. :)
<nsh> someone available has a ' model name : Quad-Core AMD Opteron(tm) Processor 1381 '
<nsh> unsure if this is latest generation
<gmaxwell> Alas, thats pre bulldozer, so pretty different from the most recent arch. I think I have one of roughtly that generation available.
<nsh> ah, shame
<nsh> maybe if you write them a nice email...

<maaku> kanzure: interesting. i've seen and used the term myself in conversation, but google results and log greps are confirming your result
<nsh> well, there was that one timeline where the blockchain became self-aware and nearly destroyed all human civilisation and we had to retrocausally elide all the theory that immanentised the cryptoeschaton
<nsh> so maybe you're remembering sideways or something
<maaku> nsh: must be it
* maaku remembers to go work on his skynet branch
* nsh nods
<nsh> hehe

<TD-Linux> gmaxwell, is ECC ram a requirement? if not I think the consumer ones would be even better
<gmaxwell> I'm interested only in ECC capable parts; but others might not be.. knowing how well a particular microarchitecture does should generally well enough.
<gmaxwell> I just don't have any idea how well they perform.. the current generation intel atom stuff is much slower than you'd expect.
