Why is the Suzanne falling through the carpet? Suzanne has collision and rigid body physics and the floor has cloth physics with collision. I want Suzanne to fall on the cloth and it should slide on the cloth. what am I doing wrong?
I'm trying to have a surface with soft body hold obects that are falling on it with rigid body physics, but for some reason, no what matter what mass I give it, the objects just fall trough the softbody enabled surface.  Is there a toggle or a value I need to change to make them stay there?

Prove the following $A \setminus (B\setminus C) = (A\setminus B)\cap (A \cup C)$ I want to prove the following so I decide to rewrite the RHS  $$A \setminus (B\setminus C) = (A\setminus B)\cap (A \cup C)$$ $$ A\setminus(B\setminus C) = A\setminus (B \cap C^c) = A\cap (B\cap C^c)^c = A\cap(B^c\cup C) = (A\cap B^c)\cup(A\cap C) $$ there is way that $(A\cap B^c)\cup(A\cap C)\rightarrow (A\setminus B)\cup(A\cap C) = (A\setminus B)\cap (A \cup C)$?  thanks. EDIT  LHS: $$x\in A \vee x\in A\cap C \rightarrow x\in A \wedge x\in C$$ RHS: $$x\in A \wedge x\in A\cup C \rightarrow x\in A \vee x\in C$$  how it can help me?

The problem seems to occur when I try to post some code with 'd--- table' in it, where 'd---' is replaced by the word drop.  I cannot post the following 3 lines, in either SO or this site, if they include the well-known SQL statements DROP.  stat.executeUpdate('d--- table if exists people;'); stat.executeUpdate('create table people (name, occupation);'); prep = conn.prepareStatement(...

UPDATE: Never mind. I don't know what the answer is, but the same problem occurs on Google's website. So it's not stackoverflow. Now to go to my IT Dept... File changed listener in Java I'd like to be notified when a file has been changed in the file system. I have found nothing but a thread that polls the lastModified File property and clearly this solution is not optimal. Was mathematics invented or discovered?

Can NDSolve handle discontinuous data? Shortest distance between $2$ lines with direction vectors Let L1 be the line passing through the point $P_1=(−11, 10, −1)$ with direction vector $\vec d_1=\begin{bmatrix}−2\\ 3\\ −1\end{bmatrix}t$, and let $L_2$ be the line passing through the point $P_2=(−8, 9, 10)$ with direction vector $\vec d_2=\begin{bmatrix}−1\\ 3\\1\end{bmatrix}t$. Find the shortest distance, $d$, between these two lines, and find a point $Q_1$ on $L_1$ and a point $Q_2$ on $L_2$ so that $d(Q_1,Q_2) = d$.   I dont really understand how to properly approach this question, how do i start? On freedom in Sartre's existentialism I am reading "Existenstialism is a humanism", the text of the famous conference by Sartre in which he explains his own version of existentialism. I think is full of logical inconsistencies, but maybe it's just because I don't understand it or I don't know enough about existentialism. Anyway, my question is about a specific passage. After having "demonstrated" that there is no way one can derive an ethics outside of Man (God does not exist and reason is insufficient), he asks himself according to what principle a person should behave and he says:     "For I declare that freedom, in respect of concrete circumstances, can   have no other end and aim but itself; and when once a man has seen   that values depend upon himself, in that state of forsakenness he can   will only one thing, and that is freedom as the foundation of all   values. That does not mean that he wills it in the abstract: it simply   means that the actions of men of good faith have, as their ultimate   significance, the quest of freedom itself as such."   So it seems Sartre says that when deciding a course of action, people will always choose "freedom," (and also, elsewhere, that "freedom" is always a good thing). That is for him the only principle, the only moral that governs or should (because we can do wrong judgments about what is freedom) govern our action.  My questions are:  1) do I understand correctly Sartre's thinking?  2) He says: a) freedom is absolute; b) the values that man chooses are also absolute because no God or reason can tell him what to do, c) therefore man will choose freedom. Is there any logic in this statement? If I replace freedom with X where X is "pleasure" or "justice" or "pain" or "zero temperature", wouldn't I "demonstrate" by this logic that man will choose X?  3) assuming what I said makes any sense, how can existentialism ever find a rule of moral conduct? and if it does, what is it and how can be demonstrated? and if it cannot, why is or has been important at all as a philosophy?

However, I can not access example.rhcloud.com now. My custom domain is www.example.com.  To avoid duplicate content problems, I tried this redirection.   Here is my .htaccess file:  RewriteEngine on   # Uncomment the following lines to force HTTPS #RewriteCond %{HTTP:X-Forwarded-Proto} !https  #RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [R,L]   # WordPress Defaults RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L]  # Redirect Https traffic to Http RewriteEngine on  RewriteCond %{SERVER_PORT} ^443$ [OR] RewriteCond %{HTTPS} on RewriteRule  ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]   # Redirect non-www to www RewriteEngine on  RewriteCond %{HTTP_HOST} !^www\.

How do I fix this?  Also, I see that since I have https to http redirection and non www to www redirection, my blog has been loading slow. How can I reduce it to lesser number of rules?  Edit:  In chrome:   In Firefox:     The page isn't redirecting properly, Firefox has detected that the server is redirecting the request for this address in a way that will never complete.
