got me thinking. There have been cases, very occasionally, where upon reading the question I get the sense that the asker is looking to do something evil: spam, black-hat hacking, mass email scraping, rootkits and so on.  Typical signs are a new user, asking about a precursor to a sketchy task (for example, ), without contextual details or further explanation.  Judging by the disparity in the ones I'm seeing and the ones I was able to find in search, usually these questions get closed and deleted or go unanswered. Some are answered, though.  I'm curious as to the community's thoughts -- is it our job to be judging askers on their perceived intent? Should we flag for this if we have sufficiently strong evidence the answer will clearly be used for evil purposes, if it's otherwise an on-topic Stack Overflow question?  (It's not as clear-cut as you might think -- as an security researcher I blur this line all the time, and thus have strong feelings about the ethical responsibilities of people who play with that particular fire. There have been times when I've written up a full, complete, multi-paragraph answer, read the question through a few more times, sighed, and deleted the whole thing because I didn't like what I might be helping someone do. I'm curious if anyone else has had this experience, and what they've done: sometimes I've left a comment, but mostly I just move on.)
How should we treat questions that are, or have seeds of, evil or malicious purposes and actions, such as writing spambots and malware?    Should they be answered like regular "everybody keeps their pants on" questions? Or should there be some other type of response to this bad behaviour lot?
Version Control: Entire site or just pieces? I've been using git to track changes in the plugins and themes I've developed for different sites. Each plugin or theme has their own repository in whichever local install of WordPress I happen to be using for that project. This works fine when I'm just working on one solitary plugin or theme.  But when I have a local version of an entire site which is a collection of different plugins, themes, WordPress core, etc. Should I be keeping that entire directory under version control?  Is there a best practice to always have a collection of repositories for each theme/plugin, or for each client site to have one monolithic repository that includes all the code used in the project (including the latest copy of WordPress via svn.) After monitor calibration colors on my two monitors are still different, why? Insert results of a stored procedure into a temporary table Why do I get a segmentation fault when writing to a "char *s" initialized with a string literal, but not "char s[]"? The following code receives seg fault on line 2:  char *str = "string"; str[0] = 'z';  // could be also written as *str = 'z' printf("%s\n", str);   While this works perfectly well:  char str[] = "string"; str[0] = 'z'; printf("%s\n", str);   Tested with MSVC and GCC.

Suppose I am a naturalized citizen of the US, but also a citizen of another country, "XYZ". I then boarded a plane and left the US to another country (maybe not necessarily to XYZ), without first getting a US passport, but using my old, but valid XYZ passport.   In this case what would be the best documents to have for me to gain entry back into the US as a US Citizen without a passport?  Would I need to contact the US Embassy for help in order to be able return?  If the airline does let me aboard to return to the US, even without the US passport, what are the best documents could I show at the border to prove I am a US citizen but that I just don't have a passport, for whatever reason? What's the fastest and easiest to read implementation of calculating the sum of digits?  I.e. Given the number: 17463 = 1 + 7 + 4 + 6 + 3 = 21 Low output volume Confused!

Are there any differences between "I have to go", "I had to go", "I've had to go", "I get to go", "I got to go", "I've got to go"?  In which situation is each term used?  I checked this dictionary , &amp; found that      get to do something:  to have the opportunity to do something   Seem like if you have a opportunity to do something, then use "get".  The expression is in present but why we use present perfect tense (Ex: I've got to go) here? Efficiently reverse the order of the words (not characters) in an array of characters Prove that for all non-negative integers $m,n$, $\frac{(2m)!(2n)!}{m!n!(m + n)!}$ is an integer. Prove that for all non-negative integers $m,n$, $\frac{(2m)!(2n)!}{m!n!(m + n)!}$ is an integer.   I'm not familiar to factorial and I don't have much idea, can someone show me how to prove this?

I want tail -f /var/log/syslog | grep it with pattern "arpwatch" and send every line to myself via jabber: xmpp username@jabber.server using xargs  tail -f /var/log/syslog | grep arpwatch | xargs sendxmpp username@jabber.server   no working.  but tail  /var/log/syslog | grep arpwatch | sendxmpp username@jabber.server   works well.  I think it's some fundamental thing about xargs and tail -f that I don't understand. How to write a function (piecewise) with bracket outside? Place label in middle of line with TikZ What is the best way to place a label in the middle of a line with TikZ? I mean smack dab in the middle of the line, not above or below it. The following is close  \begin{tikzpicture} \draw[|-&gt;, color=red] (-4cm, 0.5cm) -- (2.5cm, 0.5cm) node[midway, color=black] {$\tau_{r}$}; \end{tikzpicture}   But the line crosses right through the node and its text, which is bad.  I don't know if there is an option to choose the background color of a node, which I think would solve the problem (e.g. background=white). fill doesn't seem to work. SharePoint People.aspx Page is Visible for All Users The SharePoint People.aspx page is visible for all users by default. Is there any way to restrict this page from certain readers? biblatex, biber, is it possible to \printbibliography between two years? With biblatex and Biber, is it possible to print all the bibliography (\printbibliography) from (let's say) 2003 to 2008 in one section? And then in another section print all the bibliography from 2009 to 2016? Find the maximum likelihood estimator for $\theta$ when $f(x)=2\theta^{-2}x, 0\leq x \leq \theta$ Find the maximum likelihood estimator for $\theta$ when $f(x)=\frac{2x}{\theta^2}, 0\leq x \leq \theta$.  This should be a really easy question but I somehow cannot seem to get the right answer. My likelihood function is $\prod\limits_{i=1}^n \frac{2x_i}{\theta^2}$ which gives me after some simplification $n\ln(2\theta^{-2}) + \sum\limits_{i=1}^n ln(x_i)$ as my log-likelihood function. Then the derivative becomes $\frac{-2n}{\theta}$. If I equate this to $0$ to obtain the maximum I obtain $\hat{\theta}\rightarrow\infty$. However, this answer does not seem plausible. What did I do wrong?
