Why is the privilege gap between 250 and 1000 so large? Why is the privilege gap between 250 and 1000 so disproportionally large? I'm not taking about absolute difference as clearly the 5000 difference between 10000 and 5000 is larger but looking at a graph of the privileges gained up to 2500 rep, there's a disproportionally large jump from 250 to 1000.     Has the idea of adding/moving a privilege to 500 been considered? Why was it rejected?  There does seem to be a rough pattern of large increase, smaller increase between 20 rep and 2500 rep. I guess I could see this as kind of a "weeding out period" that attempts to dissuade users only in it for the rep but the rep itself (as opposed to the privileges) still increases and would partially mitigate that attempt.  Fair warning, I'm very close to 500 rep on my SO, so its entirely possible I'm biased.  Edit:  Just noticed . Did not see it earlier. My bad
Propose a privilege to sit in the 500 reputation mark As , the retag privilege serves a lot more confusion and a lot less of its benefit due to the suggested edit system. It must be done away with. It will be done away with. ♪  In light of this decided course of action, we're going to need a new snack for the road between "Create Tags" at 300 reputation and "Established User" at 1000 reputation. We'd like your help in thinking about some ideas on what would be a nice privilege to sit at this level. Since we're... a bit dry on our end.  The primary guideline in deciding what kind of privilege to put here is acknowledging its position in the overall hierarchy of privileges. 500 reputation is an early-intermediate user, one who has started to really get the hang of the site and its function. It can be something that provides convenience in how they currently can act on the site, or it could be some new functionality that fits as an early ability (especially considering there's no new abilities until 2000 reputation's "Edit Everywhat" ability).  I look forward to hearing what creative ideas y'all can provide.
Did I "get" (or "take") my degree "from" (or "in") the University of Somewhere? I would like to know what is the preferred way to indicate that I took a degree in some subject while also naming the place where I obtained the degree from:   I got my master's degree from the University of Somewhere; I got my master's degree in the University of Somewhere; I took my master's degree in the University of Somewhere.   I would say that "in" is more suitable to mention the particular subject (a degree in maths, for instance) than to indicate the place, but I still have doubts.  By the way, is it a "master's degree" or a "Master's degree"? Simultaneously merge multiple data.frames in a list I've seen sign in methods using  as an authentication provider, for example : (AWS Cloud9)        Is it possible to authenticate into Stack Exchange using this method? At the moment there's other methods such as OpenID, Google, Yahoo and Facebook, but it would be interesting to also have the GitHub authentication. What if client doesn't like any logo design concept? Symmetric encryption construction (meet-in-the-middle attack) This is a question I had from an exercise session.  First we do DES in CBC encryption mode using a key $K_1$ and $IV_1 = O^n$. Then we do DES in ECB decryption mode using $K_1$. And then DES in CBC decryption mode with a secret $IV_2$ and key $K_2$.  Is this construction safe against meet-in-the-middle attack?  Wouldn't the first two operations negate themselves because $C_1$ would decrypt into $P_1$? How can I resolve the error "cannot execute binary file"? When I login using SSH, all I can see is this...  -bash: /usr/bin/id: cannot execute binary file -bash: [: : integer expression expected   I couldn't do anything in here. Commands such as halt, poweroff, reboot will return command not found.  How can I fix this? I am using Debian Squeeze Linux How can I port forward with iptables? When does a complex matrix have a square root? What is the neccessary and sufficient condition for a matri$A \in C^{n  \times n}$ so that it has a "square root" , that is there is a matrix $B \in C^{n \times n}$ such that $A=B^2$.  I am not quite sure but I was thinking that it would be that A and B are similar. Converting PostGIS point to text causing loss of data? I have a road network and want to test connectivity between the features.  I am having trouble with two specific features, the rest of the dataset is functioning just fine.  When I get those 2 links' start &amp; end locations using ST_StartPoint and ST_EndPoint, the result is that they are slightly different.  However, when I convert the result to text by wrapping it like so:  ST_AsText(ST_StartPoint(geom)) and ST_AsText(ST_EndPoint(geom))  then the results are exactly the same.  Is it possible they are actually off by a tiny amount like .000000001 and the ST_AsText loses a decimal point? I am trying to do a clean install of the octave3.2 package.   To do this, I removed it, then tried to reinstall it.   When I reinstalled, an error occurred. It could be a bug in the package, but I want to make sure I have everything removed so that I can do a clean install.  Is it enough to do this?  sudo apt-get --purge remove octave3.2 How do I get a list of obsolete packages? I'm trying to figure out a way to get a list of the packages that are no longer available in the repositories that I have enabled. This workstation has been through quite a few versions of Ubuntu and has had many 3rd party repositories added and removed. I'd like to get a list of software that I have from these removed repositories, so I can clean it up or add back the appropriate repositories. I'm looking for a word which describes a task which I think is poorly designed and will lead to either mediocre results or failure, but which I have to do anyway, especially in a work setting.   The word "Dilbertian" comes to mind, however this word is obviously made up and is only meaningful to someone who is familiar with the Dilbert comic strip, so I'm looking for something which captures both the futility and compulsory nature of the task in a way which is meaningful to a broader audience. Syntax error while defining an array as a property of a class Given $f_{n} : [a,b]\rightarrow \mathbb R$ is uniformly Lipschitz and $f_{n}\rightarrow f$, how can I show that $f$ is Lipschitz?  $f_{n}$ is uniformly Lipschitz $\leftrightarrow \exists K &gt; 0$ such that for all $n$ and for every $x,y\in [a,b]$ we have $|f_{n}(x)-f_{n}(y)| &lt; K|x-y|$.  $f_{n}\rightarrow f \leftrightarrow \forall~\epsilon&gt;0~~\exists~N$ such that $\forall~n&gt;N$ we have $\mid f_{n}(x) - f(x)\mid&lt;\epsilon~~~(=\mid x-y\mid?)$  Then we have  \begin{align} |f(x)-f(y)| &amp;\leq |f(x)- f_{n}(x)| + |f_{n}(y)-f(y)| + |f_{n}(x)-f_{n}(y)| \\ &amp;\leq |x-y| + |x-y| + K|x-y| \\ &amp;\leq (K + 2) |x - y| \end{align}  which shows that $f$ is Lipschitz. Can anybody tell me if this makes sense? Sorry if layout is poor. Internal microphone not working I have an internal microphone in my laptop. I think it uses Intel High Definition Audio.

Counting files in leaves of directory tree In an urn there are $n$ red balls and $m$ blue balls. I extract them without replacement. Let $X$=time of first blue. What is $E(X)$?  I found PMF of $X$ and it is, if $k &gt; n+1$  $$P(X=k) =\frac{n(n-1) \dots (n-k+1)m}{(m+n)(m+n-1) \dots (n+m-k+1)}$$  How could I evaluate $E(X)$?  Edit: I'm looking for an explicit form of $E(X)$ How can I show that the order of an element modulo $n$ divides $\phi(n)$?  I know that if $a$ and $n$ are relatively prime, then the least positive integer $x$ such that $a^x\equiv1\pmod n$ is its order modulo $n$. I also know that, by Euler's theorem, $a^{\phi(n)}\equiv1\pmod n$. Therefore, it must be the case that $x\leq\phi(n)$.  However, all that I am left to do is to show that $kx=\phi(n)$, for some integer $k$. Do you guys have an idea on how to do this? Thanks in advance! How can one cite theorems of references? Which offences result in indirect free kicks? If a player commits a direct free kick offence in their own penalty area, this results in a penalty kick instead of a direct free kick. However, if the offence is an indirect free kick offence, it remains as an indirect free kick .  What offences result in an indirect free kick?
