Migration flags and votes should be removed from the close menu. Instead, along with "share, edit, close, flag" at the bottom of the question, there is a "migrate" option.  When you click this, you will always have the option to migrate to that site's Meta page.  Beyond the meta site, however, the migration options are limited to sites for which you have a user account on (and there should probably be a soft-search menu in here for our particularly eclectic users).  More importantly, whether your migration vote counts as a flag or an actual migration vote depends on your rep on the migration target site.  If you're at 3,000 or more rep on the target site, your vote counts as an actual vote.  If you're below this, it shows up in the review queue on the target site.  So for example, let's say I'm a Stack Overflow user with over 3,000 rep. I'm also a user with a DBA account with less than 3,000 rep, and a Code Review account with over 3,000 rep.  If I see a question on Stack Overflow which looks like it'd be better posted elsewhere, I can flag it for migration to DBA (if that looks right to me) (which pops it up in the review queue for other DBA users with over 3,000 rep on DBA and SO to vote in agreement with my flag), or I can vote it for migration to Code Review (if CR looks appropriate to me).  Currently, if you try to vote a question to migrate away from Stack Overflow, you are presented with the following menu:    And it doesn't matter who you are, these are the five migration options you get.  And the fact of the matter is, I know I personally shouldn't be allowed to migrate to TeX or Stats.  I don't have an account on either of these sites, nevermind having in the slightest clue what sorts of questions on are on topic there.  Meanwhile, I do have a Super User account, and I do have a DBA account, but I have exactly 101 rep on both of these sites.  I've never asked a question, posted an answer, or even so much as left a comment.  I think I only created an account on these sites because I was thinking about asking a question or I wanted to upvote someone's answer (I have a use for these sites, but not much to contribute).  Meanwhile, there are other Stack Exchange network sites that have some potential for overlap with Stack Overflow.   Android Enthusiasts Ask Different Ask Ubuntu Drupal Answers Electrical Engineering Game Development Information Security Programmers Server Fault Theoretical Computer Science Unix &amp; Linux User Experience Webmasters WordPress Development   This list only includes graduated sites whose designs have been completed.  There are even more if we count beta sites (or graduates sites whose designs aren't yet completed, like ).  But, I don't think all of these sites should be in the list either.  , I am primarily talking about the list of migration targets being dynamically generated for each member based on which other sites they are members of.  If you don't even have an account at the target site, how can you possibly know that this question is better suited here than there?
With all the new sites up and running it gets more and more difficult for users to really know the scope of a site and thus a lot of questions a migrated to places where they are (probably even more) off-topic, see e.g. . So I request the opposite of :  Allow migration if you have enough rep on both the source and the target site (the target reputation required could be a bit lower, say 5001)  That way questions could only be migrated by users familiar with the scope of both sites who can really estimate where the question is better. Maybe those who don't have the rep on the target site could still be able to cast a flagging-only-but-not-counting-as-vote vote...  1) Courtesy of

I read and loved  but with all the recent changes to what is and isn't canon I'm losing track.  There's a common theory that Supreme Leader Snoke is Darth Plagueis, most are discounted because Plagueis is a Muun. But where does that information come from? What current canon information do we have about Plagueis that disproves this theory and what has been marked as Legends? Changing console font on Ubuntu 10.04 Server How can I change local console font on Ubuntu 10.04 Server to Inconsolata? I have been texture painting in look dev mode. But when i try to render it, everything looks very dark. I have 3 sun lights in my scene, ambient turned on in Eevee settings. What am i missing? I really like the look of my scene in Look Dev mode, how can i achieve the same look when my scene is rendered too? What are alternatives to ExtJS? So what I'm looking for is a javascript framework I can use that has several UI controls. I have taken a look at  but those controls are very basic compared to ExtJS. Are there any other competitive alternatives?     This question exists because it has historical significance, but it is not considered a good, on-topic question for this site, so please do not use it as evidence that you can ask similar questions here. More info: . I'm trying to prove : Given a simple graph $G$ with $n$ vertices, where $n$ is even, prove that if every vertex has degree $\dfrac n2 + 1$, then $G$ must contain a (simple) $3$-cycle. A (simple) $3$-cycle is a set of $3$ (distinct) vertices, $a, b, c$ such that $ab$ is an edge, $bc$ is an edge and $ac$ is an edge.  I know there are similar ones already on here, but I can't comprehend any of the answers. This is what I have so far:  Base Case: Since the graph has to have at least $3$ vertices to have a simple $3$-cycle, the lowest possible even number of vertices is $n = 4$.   $\dfrac42 + 1 = 3$ degree (edges attached to node). This means each vertex connects to each of the other $3$ vertices since $G$ is a simple graph. Thus, any combination of $3$ vertices will be a simple $3$-cycle.  Inductive Hypothesis: Assume a simple graph with $k$ vertices, where $k$ is even, contains a simple $3$-cycle if each vertex has degree $\dfrac k2 + 1$.  Inductive Step: Since only concerned about when the graph has an even number of vertices, going to show a simple graph with $k + 2$ vertices, where $k$ is even, contains a simple $3$-cycle if every vertex has degree $\dfrac{k+2}{2} + 1$   This is as far as I get and don't know how to finish the Inductive Step (Also please feel free to let me know if I messed anything up, up to this point) Combine rows / concatenate rows How do I left-align entries in a matrix with \begin{matrix}? I'd like to left align the -1 entry in the following matrix so that the 1s line up. Is there a way to get matrices to ignore signs in that way?  \begin{matrix}     1 &amp; 1  \\     1 &amp; -1 \\ \end{matrix}   Using \flushright{-1} doesn't seem to work. Say, we have a query like this:  select a.*,b.* from  a join b on a.col1=b.col1 and len(a.col1)=10   Assuming the above query uses a Hash Join and has a residual, the probe key will be col1 and the residual will be len(a.col1)=10.  But while going through another example, I could see both the probe and the residual to be the same column. Below is an elaboration on what I am trying to say:  Query:  select * from T1 join T2 on T1.a = T2.a    Execution plan, with probe and residual highlighted:         Test data:    create table T1 (a int, b int, x char(200)) create table T2 (a int, b int, x char(200))  set nocount on declare @i int set @i = 0 while @i &lt; 1000   begin       insert T1 values (@i * 2, @i * 5, @i)     set @i = @i + 1   end  declare @i int set @i = 0 while @i &lt; 10000   begin     insert T2 values (@i * 3, @i * 7, @i)     set @i = @i + 1   end   Question:    How can a probe and a residual be the same column? Why can't SQL Server use the probe column only? Why does it have to use the same column as a residual to filter rows again?  References for test data: I want to programmatically create a new column in an MS Access table.  I've tried many permutations of ALTER TABLE MyTable Add  MyField DECIMAL (9,4) NULL; and got:      Syntax Error in Field Definition   I can easily create a number field that goes to a Double type, but I want decimal.  I would very strongly prefer to do this in a single ALTER TABLE statement and not have to create a field and then alter it.   I am using Access 2003. Allowing all/different file type uploads I know this is a really basic question, but I've just started with some basic C++ programming after coding a few projects with high-level languages.   Basically I have three questions:   Why use pointers over normal variables? When and where should I use pointers? How do you use pointers with arrays? How do CSS triangles work? When to use \LetLtxMacro? Frequently I see users redefine macros using (for example)  \let\oldmacro\macro% Store \macro in \oldmacro \renewcommand{\macro}{%   % ...redefined \macro   \oldmacro% }   and other times they use  \usepackage{letltxmacro}% http://ctan.org/pkg/letltxmacro \LetLtxMacro{\oldmacro}{\macro}% Store \macro in \oldmacro \renewcommand{\macro}{%    % ...redefined \macro   \oldmacro% }   Why would one use \LetLtxMacro when \let works just as well? Or, more specifically, when would one use \LetLtxMacro and/or why? Is there a way to respec attributes? Are there any distinct finite simple groups with the same order? In finite group theory, it's often quite easy to show that there are no simple groups of a given order $n$.  My question is different: is there some natural number $n$ such that there are two non-isomorphic simple groups of order $n$?  The two easiest families of finite simple groups - $\mathbb{Z}_p$ for $p$ a prime and $A_n$ for $n\ge5$ - clearly don't yield any examples.    It should be possible to check this using the , but I don't know enough about the fabled 'sixteen infinite families of groups of Lie type' to do the check myself.  Also, if the answer is 'no', I'd be much more interested to see an elementary(ish) proof than I would be to see a proof that relies on over 3,000 pages of non-stop hard group theory.
