probably the most common misconception about asnycio is that it lets you run any task in parallel - sidestepping the GIL (global interpreter lock) and therefore execute blocking jobs in parallel (on separate threads). it does not!

Flask also allows access to a CombinedMultiDict that gives access to both the request.form and request.args attributes under one variable.
This example pulls data from a form field name submitted along with the echo field in the query string.

The Assets folder is the most common place to store your GLSL-ES shader files. To use them in your OpenGL ES application you need to load them to a string in the first place. This functions creates a string from the asset file:
private String loadStringFromAssetFile(Context myContext, String filePa...
The traditional GLSL compilation model involves compiling code for a shader stage into a shader object, then linking multiple shader objects (covering all of the stages you want to use) into a single program object.
Since 4.2, program objects can be created that have only one shader stage. This met...
If Errorlevel 1 (
Echo Errorlevel is 1 or higher
REM The phrase "1 or higher" is used because If Errorlevel 1 statement means:
REM If %Errorlevel% GEQ 1

This is a unit test of a component that has Store as a dependency. Here, we are creating a new class called MockStore that is injected into our component instead of the usual Store.

This is a unit test of a component that has Store as a dependency. Here, we are able to use a store with the default "initial state" while preventing it from actually dispatching actions when store.dispatch() is called.

Occasionally we see StackOverflow Java questions (and C or C++ questions) that ask what something like this:
i += a[i++] + b[i--];
evaluates to ... for some known initial states of i, a and b.
Generally speaking:
for Java the answer is always specified1, but non-obvious, and often difficult ...

Consider the tree:
Lowest common ancestor of nodes with value 1 and 4 is 2
Lowest common ancestor of nodes with value 1 and 5 is 3
Lowest common ancestor of nodes with value 2 and 4 is 4
Lowest common ancestor of nodes with value 1 and 2 is 2
P( glasses | reading ) = Count( reading glasses ) / Count( reading )
We count the sequences reading glasses and glasses from corpus and compute the probability.
Consider the BST:
Lowest common ancestor of 22 and 26 is 24
Lowest common ancestor of 26 and 49 is 46
Lowest common ancestor of 22 and 24 is 24
Binary search tree property can be used for finding nodes lowest ancestor
Psuedo code:
lowestCommonAncestor(root,node1, node2){
if(root == NULL) ...
