I was trying to ProxyPass the app to another server But ran into a strange problem. ProxyPass worked when I called http://10.0.11.95 but failed when any uri was added to root(10.0.11.95) Like http://10.0.11.95/login gave Proxy Error The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /login. Reason: DNS lookup failure for: 127.0.0.1:9051login Where we find the problem is: Code for ProxyPass: ProxyPass               / http://10.0.11.95 ProxyPassReverse        / http://10.0.11.95 Solution, I needed another slash at the final, so, it should be: Code: ProxyPass               / http://10.0.11.95/ ProxyPassReverse        / http://10.0.11.95/ Now it works \m/ .

Today I was stumped by a very simple yet awesome problem by my friend Sandip What is the answer of   :  7 % -2  and to the surprise ruby irb printed it as :  -1  After some research I what I found about this and why here is explanation and links From Ruby Programming Language, O,really   Division, Modulo, and Negative Numbers When one (but not both) of the operands is negative, Ruby performs the integer division and modulo operations differently than languages like C, C++, and Java do (but the same as the languages Python and Tcl). Consider the quotient -7/3. The floating-point result is –2.33. The result of integer division must be an integer, however, so this number must be rounded. Ruby rounds toward negative infinity and returns –3. C and related languages round toward zero instead and return –2. (This is just one way to characterize the results; no floating-point division is actually done, of course.) An important corollary of...
