@RM Physicists are often sloppy and what they mean by connected is weakly connected. My impression was that this is what the OP meant.

@Szabolcs My problem is that I know next to nothing about graph theory and terminology :) My naive assumption is that a sink is a vertex that has only incoming edges (VertexOutDegree of 0) and vice versa for sources.

Q: Changes after graduation

ndroock1Background: In a discussion elsewhere about graduation I read that after graduation the number of users on Mathematica Stack Exchange will increase significantly ( Leonid called it rapid expansion ). Considering that: 1) If I do a search on a Mathematica related issue a Stack Exchange questio...

I would like to close this as a duplicate of this. Please vote to close if you agree.
The comments to this question need to be cleaned up. Please consider summarizing any important points in an answer and then flagging comments as obsolete.

@Szabolcs OK, that would make more sense. It wasn't clear to me from the example in the question whether the OP meant strongly or weakly connected.

Finally, some of our stuff is getting shared by SE's G+ account

@RM re your comment on needing high-rep users to clean up, I agree. recently there has been an increased need for closing/deleting, so maybe it would be more of a problem to keep things working well if some people lost privileges
(although apparently some of the offenders are self-moderating!)
hi @MrWizard
 
user1390 set a new low for contribution quality and civility. :-/ Golly gosh I hope Leonid isn't right that graduating from Beta will bring in more of him.
 
acl
I don't see a mechanism for this to happen, though
 
@acl do you think the question I marked above should be closed as a duplicate?
 
R.M
@MrWizard I voted and the OP himself agrees...
 
acl
I was reading it now
 
10:50 PM
@RM okay; @acl thanks
 
R.M
@acl I don't really think so... we have 30+ people who can close (in a graduated site) and 4 non-mods who can delete (with more who'll get there in a month or so). Even if stuff doesn't get removed instantly, closure + downvotes is sufficient and the mods can remove posts
As long as there's closing + voting + editing going on, we needn't worry about deletion.
 
acl
@RM I don't remember what is the threshold for voting to close?
 
R.M
3k
 
acl
@RM you're right, it should be OK then
 
R.M
Since we're on the topic, publicizing this link is probably useful for those who aren't aware: Posts that are on their way to deletion (votes in the last 30 days) can be found here in the /tools section. Please visit that at least once a week to see what you're willing to vote to remove.

I always keep hitting "You've already voted to delete this" (I wish it indicated differently if I've already voted)
 
acl
10:57 PM
@RM so do I... at least it indicates we're consistent
(or the only two jerks who delete questions)
 
R.M
Another place to look for is by searching for closed questions and sifting through the non-duplicates (or useless dupes)... This is admittedly a bit more cumbersome since there isn't a good way to weed out the duplicates from other closed questions. Hopefully there might be some changes soon
@acl ha!
 
Let us not be over zealous in deleting Closed questions; they serve as useful stubs for searches in many cases, and help to reduce new duplicate questions.

R.M
You mean questions closed as "not-constructive", "too localized" or "not a real question" too? They can't be both useful and closed at the same time... (I'm not advocating deleting dupes)
 
acl
@MrWizard I think most actually deleted questions really are not useful to keep on the site
 
Oh, another weird behaviour
I'm in a row
 
R.M
11:06 PM
row jo?
 
Haha
y = 9;
DynamicModule[{x, y},
x = If[y == 9, Print["a"];, Print["b"]];
]
Now, that shouldn't print "a" at all, right?
y = 10;
DynamicModule[{x, y},
x = If[y == 9, Print["a"];, Print["b"]];
] doesn't
The second prints "b"
So it's definately using the unscoped version of "y", even if it stores x as if it didn't know the value of y. Leaakyy
 
R.M
11:23 PM
@Rojo The If doesn't really get evaluated... I wonder why it prints a. Don't think it is using the unscoped version of y
You can force evaluation with === or TrueQ[y==10]
 
R.M somehow it does. You can replace the Print with a p=23 and p gets the value, you can put a Pause, etc
and "which side of the if" gets evaluated depends on the outside value of y
 
R.M
Not if the evaluation of the condition is forced... but I agree that without it, If does get evaluated somehow (outside of the DM, maybe?)
 
Now that's even weirder
 
R.M
But using y==10 isn't correct in an If statement
 
Why?
That's why it has the optional third argument
Meant fourth
 
R.M
11:29 PM
That's correct, but using it and not using the fourth seems awkward (at least to me)
If[y == 10, Print["a"];, Print["b"];, Print["c"];] correctly prints c
 
Interesting

@MrWizard How does the site's visits/day stats look like? I saw that it had dropped to <1.3k a couple of days ago and now it's at 1.4k... Could you post a screenshot (redacted, if necessary)
 
@RM Other than a couple of big spikes, one up to about 4000, we're holding level at about 1300 visits per day since mid April.
 
How do yo check that @MrWizard?
 
R.M
@MrWizard Heh, that was the boggle question. My link share was quite popular (got lucky)
 
@Rojo It's a Moderator tool.
