Enumeration types can also be declared without giving them a name: enum { buffersize = 256, }; static unsigned char buffer [buffersize] = { 0 }; This enables us to define compile time constants of type int that can as in this example be used as array length.

Julia uses the standard mathematical meanings of arithmetic operations when applied to matrices. Sometimes, elementwise operations are desired instead. These are marked with a full stop (.) preceding the operator to be done elementwise. (Note that elementwise operations are often not as efficient as...

There is a mantra that some Java experts are wont to recite: "Exceptions should only be used for exceptional cases." (For example: http://programmers.stackexchange.com/questions/184654 ) The essence of this is that is it is a bad idea (in Java) to use exceptions and exception handli...

$sku = 'some-sku'; $productId = Mage::getModel('catalog/product')->getIdBySku($sku); if($productId){ //sku exists }

A for loop iterates from the starting value down to the ending value inclusive, as a "count-down" example. program CountDown; {$APPTYPE CONSOLE} var i : Integer; begin for i := 10 downto 0 do WriteLn(i); end. Output: 10 9 8 7 6 5 4 3 2 1 0

In order to avoid a divide by zero with a numberSet (what you get after a reduction like avg()) you can short-circuit the logic: $five = min(q("sum:rate{counter,,1}:haproxy.frontend.hrsp{}{status_code=5xx}", "1h", "")) $two = avg(q("sum:rate{counter,,1}:haproxy.f...

With series operations, things are dropped from the left side if there is no corresponding timestamp/datapoint in the right side. You can mix this with the dropbool function to avoid divide by zero: $five = q("sum:rate{counter,,1}:haproxy.frontend.hrsp{}{status_code=5xx}", "1h",...
