@ACuriousMind If you were to look at his profile you'd see that he is hawking his pet theory. Fire at will.

@JohnRennie "No offense meant". None taken. Just that I felt a need to clarify, and didn't know about the change. The last time any suggested edit of mine was rejected, (well ...) was probably before these changes were introduced.
Of course, this wasn't the first time I had to get into a timeline reconstruction :P
(Mods and people with 10k will understand!)

Q: The tag wiki for resource recommendations contradicts existing tag synonyms

WrzlprmftThe tag wiki for reference-request contains the following sentences: Contrast this with the reference-request tag, which is for questions that ask for a specific resource, instead of any resource explaining a particular topic. The tags resource-recommendations and reference-request are mut...

@Qmechanic Are the tag synonyms on references not bolted on backwards? I thought the arrangement was to map books into resource-recommendations and reference-request into specific-reference.
 
3:03 PM
@EmilioPisanty : Ha. After today's edit it seems correct now, cf. today's meta post. The two current tag names were created Dec 9, 2013, cf. this meta post. Let me also ping @David Z, since he was involved in the res recom and spec ref wiki tags.
 
3:15 PM
Yeah, that's the right reference from last year.
But the implementation's wrong - reference-request should map to specific-reference; currently maps to resource-recommendations
see e.g. http://physics.stackexchange.com/questions/tagged/reference-request (note the redirect).
 
Ah, now I see what you mean. Well, after moving all ref req to spec ref, I created a NEW ref req tag. This is because new users tend to write ref req when they mean res. recom. This is confusing to people familiar with the past terminology, but it is intended to satisfy the needs of running the site in the future. The previous meaning of ref req is now obsolete and not in use.
 
@Qmechanic I pinged you because it's your name on the synonym (physics.stackexchange.com/tags/synonyms)
 
3:31 PM
So yes, it is by intention/design. We get 10 times as many res recom question than spec ref questions. So when one uses the ref req tag one gets mapped to the res recom tag in order to minimize need for retagging.

@EmilioPisanty yeah, what @Qmechanic said makes sense. In practice, 90% of the time when people type into the tag box, what they actually mean is . (As evidence, we used to have to retag to all the time)
If someone is using the tag correctly (according to its original intent), then yes, it should be converted to , but hopefully people who want to do that will see in the list that pops up and know to choose it instead. Those questions are fairly rare anyway.
 
5:15 PM
@DavidZ That's fair enough. But then the tag wikis should be altered accordingly, and a correcting answer should be added to meta.physics.stackexchange.com/questions/5281/… to document the change.
 
What needs to be changed in the tag wikis?
If you'd like to add an answer to that question explaining what happened, feel free to go ahead and do so, or if not I can do it sometime.
 
@DavidZ Oh. It was just what was in meta.physics.stackexchange.com/questions/6214/…
@DavidZ I'll try and do it in a bit. It'll have more weight if you do it, though.
 
I dunno, I'm the one who posted the question in the first place ;-) so I would encourage someone else to post the answer. It helps show community involvement or some such thing.
@EmilioPisanty gotcha. That was fixed.
 
Community involvment? What kind of witchcraft is that?
 
@DavidZ Done. Maybe get it its checkmark, though.
 
5:31 PM
Done (I made one edit)
 
@DavidZ gotcha

Q: Are the list of questions that I am seeing curated based on my past activities?

crackjackI know that there are a few different options to sort questions based on popularity, views, tags etc etc. These options give the same list to anyone who uses them at that moment. But is there any option which learns from my past activities (views, votes cast, votes received etc etc) to curate a...

Has anybody noticed how this user has a tendency to write off-topic answers which end in recommendations of some book or paper (also linked in his profile)?
 
@Wrzlprmft Yes. Flag them. Downvote them. Delete them. :)

Sure, but as this user seems to gather reputation somehow, this alone won’t stop him.
 
@Wrzlprmft If you think the content is purely promotional, use a spam flag instead of a low quality flag
Agreeing spam flags on a post carry a hefty rep penalty
 
That user is trying to leverage the high up-vote to downvote rep ratio. Answering enough easy questions with actual physics for one or two votes each can generate more than enough rep to off-set the hammering from pushing some nonsense theory elsewhere.
If gets worse if misguided people upvote the nonsense because "downvotes are mean".

The evidence on Stack Overflow is that such compensatory voting is not common, but I don't have clear data of Physics SE.
 
@dmckee How would you tell if a downvote is "compensatory" or if the upvoter honestly thinks the post is worth their vote?
 
9:16 PM
For any given vote you can't.
 
So you'd have to look at voting patterns of users and see if they upvote disproportionally many posts that had negative score before their vote?
 
You can look for statistical patterns. The study Shog9 used for stack overflow was to consider only those posts with exactly 2 votes and zero score (i.e. one up and one down). Then he asks were there more ordered up,down than down,up. The null hypothesis is that it should be random (i.e. even to within statistics).
 
Unfortunately, I cannot flag the one on my question as spam, as I already flagged it as not an answer too quickly.
 
@ACuriousMind Yeah. though I haven't seen it done for cases other than the one Shog9 used.

Q: Is there anyway to communicate with an edit reviewer?

aepryusThere is a simple grammatical error in an answer that I was trying to fix. Unfortunately, it only involved modifying 3 characters. So, I quickly lightly copy-edited the remainder of the answer making 2 other minor changes. The edit suggestion was than quickly rejected. Is there anyway to just...

 
9:25 PM
Here's the post where Jeff Atwood, not Shog9 introduced his data. I applied counting statistics in a answer down there somewhere. The results are ... interesting.

9:42 PM
@dmckee So, if I understand your procedure correctly, you test against the assumption that among questions with +1/-1, it should be equally likely that the +1 came first as that the -1 came first. And you find that on SO, for questions it is more common that the -1 was cast first, but for answers, that the +1 was cast first, with a significance that rules out randomness.
 
Yep.
Thought "rules out randomness" is tricky.
 
That actually makes sense, I'never expected pity-voting for answers
 
I assumed counting statistics the way we mean that phrase in particle physics which may be an error.
 
@dmckee Yeah, the statisticians will be calling for my head for that one.
It's a bit weird to assume counting statistics because "letting people post answers on SO for years" is not exactly a repeatable experiment that we would expect to be governed by Gaussian noise, yes
 
Well, the only tool I have is a hammer, so everything looks like a nail...
There is a question about it on stats.se: stats.stackexchange.com/questions/11414/… where the pros talk it over.
 
9:46 PM
Recursion, anyone?
@dmckee Am I missing something, or are they only talking it over without ever actually applying it to the data?
 
You're not missing anything. The deal is that no one actually has access to the data except the team.
Er...actually I'm not sure that is true.
You could look in Data Explorer. In your copious spare time, of course.
 
The question on stats.SE states that anonymized voting information is available
And for their Markov chain modeling, the anonymous data is enough, I think
Hmmm...I actually do have some procrastination to do...

Q: mass-spring system in space

Mohamed Osama The answer : Can someone explain to me what is that ?

 
10:53 PM
Have any changes occurred after 2 years?
 
11:08 PM
Polling the mob: did I screw up on this? (Please look at the original version as well.)
Please only one torch, pitchfork, or attaboy per customer.
 
11:20 PM
I have re-opened the question after edits by the OP. Perhaps it is still marginal, so I am still interested in your opinions.
