We should have fun some time and dump any question that contains a number in it over to Math.SE by 3:2 vote
 
Jim
On a related note, I'd be interested in seeing a list of which sites each site has in its migration options. I know mods can migrate anywhere, but I'd still be interested to see where all the common folk are capable of sending a question
 
It would be kinda cool to see a connectivity graph
 
Jim
without going through each individual site and checking the options in the flags
 
How many migrations would it take for us to get a question on, say, Judaism.SE, using only migration pipelines
 
Jim
it may not be possible
 
9:05 PM
5 degrees of Stack Exchange
It may not be, it would be kinda cool to see what clusters are connected/disconnected from one another
It'd be a pretty cool visualization
 
@tpg2114 Are you referring to a graph of the migration options of SE sites?
So, for us, it would be math and meta?
 
@JamalS Yes -- is there one?
Correct
And from Math it could go... somewhere and somewhere else
And to see how those connections exist/propagate
 
No, but if that's all you want, it wouldn't be hard to construct. Just contact a mod on each site asking for the default options.
 
There's 133 communities
No guarantee you get a response, and that's a lot of manual data to compile
 
Jim
Ask on mother meta?
 
9:10 PM
Much easier to just do this:

Q: Is there a map of migration pathways?

tpg2114While in chat lamenting a really bad question that was migrated to a site because 3 people voted for it elsewhere, we got to wondering: Is it possible to see a map of all the migration pathways in the vote to close lists? I know moderators can move things anywhere, but what can the normal close...

 
Jim
thinking the same thing, I see
 
It seems like something the SE folks would have looked at
 
Jim
all those computer scientists with their mappings and path analysis. Why wouldn't they?
 
Or data analytic folks who would be all excited just to look at clustering
I want a graph where each connection is weighted by the number of migrations performed along that pathway
And the size of the site is relative to the activity on the site
 
Ooh, that would be nice
 
Jim
9:13 PM
That's a bonus though. Let's start with a map of just the paths
 
I'm surprised this hasn't been done already
@Jim: Paths alone are boring, those 'bonuses' are interesting
FYI: If you have Mathematica, you can do something similar for Facebook and Twitter.
Mathematica will create a complete graph/network for you.
 
@Jim Stop reading my mind. I put that exact same comment on my question
 
@tpg2114 Why comment? Edit.
 
Jim
Is it weird that I can see what you're typing? Did you know I can see you in the bathroom? Wait... is that weird? I mean like a spying on you in the bathroom in a friend kind of way
 
@JamalS Because it's actually a comment and tangential to the original question
 
9:19 PM
@tpg2114 So? Just mention it's tangential or a bonus, and separate it with one of those divider things.
Stack exchange have nice offices :)

@alarge so youre well read! afaik "frontrunning" is not technically legal if its based on "inside information". however there are gray areas & enforcement limitations of SEC. it is somewhat tricky to define strictly.
lewis & his new book is cited heavily in the blog.
in biology there is a concept of "big fish eat little fish" & the same applies to economics, and while its not always pleasant, not all that is unpleasant is illegal.... quite to the contrary....
 
9:48 PM
@vzn Well, of course the "front running" described in the book is not exactly insider trading like traditional front running (the HFTs don't really get the order, but they make an educated guess). Anyway, I do think that in principle HFTs do provide liquidity and thus also have a positive effect on the market in some respects.
 
10:00 PM
 
@pentane close it then
 
... O
 
vzn
alarge havent read the book its on my (huge) to-read pile. read some reviews. HFT is weird to anyone who hasnt heard of it. but its been around in various forms for ages.
 
but I'm not on chemistry.SE?
 
vzn
the blog says (somewhat agrees) its difficult to sort out "positive vs negative" impact of HFT...
 
10:03 PM
@pentane So how do you know it's crap for their site? Maybe it's a great question there
(Playing Devil's advocate here, I really have no idea if it's suitable for them or not)
 
The question is "Why do internal combustion engines only burn to carbon monoxide, not dioxide?" Combustion engines do produce carbon dioxide. Maybe the question can be reworded and saved I guess
 
The text of the question is better than the title
Marginally anyway
 
Yeah I suppose if the actual question is "why is CO produced at all" that's definitely a good chemistry question
 
10:24 PM
@Sofia it was the question (later migrated to math.se I think.. or maybe simpli closed as homework I don't know) where you solved that integral typical of scattering problems (I don't remember exactly what it was).
@Sofia Anyway the exact post is not important now. It was just to inform you (if you didn't know it already) that it is ok to answer your own question, and that that is probably a better choice that posting material (into which you probably put some effort) on low quality questions, where it will be hardly found by others
 
Anyone know of a review article on Bell inequality violations?
 
10:43 PM
@DanielSank yes Danny, I know - it's the most competent review possible, written by Abner Shimony himself. Do you want it?
 
vzn
DS the wikipedia page on local hidden variables is not bad. whats your interest?
do you want at a scientific or pop sci level?
 
@glance : I will look in my questions.
 
vzn
yrs ago david mermin wrote some nice expository stuff
 
@glance : Do you mean this ?

Open Science

Proposed Q&A site for scientists interested in openly sharing their research; for anyone interested in open access to research results; for publishers, librarians and other Open Science stakeholders.

Currently in commitment.

 
11:14 PM
@Sofia Yes, if you can give me a reference it would be useful.
 
@Sofia no. As I said above, I referred to one question (not asked by you) to which you answered. That question was one with a certain faith of being closed, so I was suggesting that instead of posting good material as an answer to questions that will surely be closed and even possibly migrated, you can just ask yourself an appropriate question, and post your things as an answer to that question.
 
11:35 PM
@DanielSank : here it is . It is very detailed.
@glance : Aaaa! I understand. Many thanks for your suggestion.
