Retrolambda lets you run Java 8 code with lambda expressions, method references and try-with-resources statements on Java 7, 6 or 5. It does this by transforming your Java 8 compiled bytecode so that it can run on an older Java runtime.
Backported Language Features:
Lambda expressions are back...
It is possible to use integer variables with latex. To create a new variable we need the \newcounter{name} command, where name is the name of the new counter. The name must contain only letters. This command creates a new one with name \thename. With this command we can print name variable onto the ...

The if constexpr statement can be used to conditionally compile code. The condition must be a constant expression. The branch not selected is discarded. A discarded statement inside a template is not instantiated. For example:
template<class T, class ... Rest>
void g(T &&p, Re...
This example shows how to use mathematical operations with counters. It may be useful for loops in latex.
Addition: \addtocounter{num}{n}
this command adds n to num, where num is a counter and n is a positive integer.
Subtraction: \addtocounter{num}{-n}
this command subtracts n from num, where n...

Declares a variable to have automatic storage duration. It is redundant, since automatic storage duration is already the default at block scope, and the auto specifier is not allowed at namespace scope.
void f() {
auto int x; // equivalent to: int x;
auto y; // illegal in C++; ...
There are certain principles that apply to optimization in any computer language, and Python is no exception.
Don't optimize as you go:
Write your program without regard to possible optimizations, concentrating instead on making sure that the code is clean, correct, and understandable. If it's too...
Copy the database from the emulator/phone to view it. It can be done by using ADB:
adb pull /data/data/<packagename>/files/
That command will pull all Realm files created by Realm.getInstance(getContext()) or Realm.getInstance(new RealmConfiguration.Builder(context).build()). The default d...
Nested for loops may be used to iterate over a number of unique iterables.
result = []
for a = iterable_a
for b = iterable_b
push!(result, expression)
end
end
Similarly, multiple iteration specifications may be supplied to an array comprehension.
[expression for a = iterabl...
Generator comprehensions follow a similar format to array comprehensions, but use parentheses () instead of square brackets [].
(expression for element = iterable)
Such an expression returns a Generator object.
julia> (x^2 for x = 1:5)
Base.Generator{UnitRange{Int64},##1#2}(#1,1:5)

&& chains two commands. The second one runs only if the first one exits with success.
|| chains two commands. But second one runs only if first one exits with failure.

The | takes the output of the left command and pipes it as input the right command. Mind, that this is done in a subshell. Hence you cannot set values of vars of the calling process wihtin a pipe.

Glyphicons can be used in text, buttons, toolbars, navigation, forms, etc (Source: W3Schools). Glyphicons are basically icon forms that can be used to style any of the aforementioned. These examples outline the usage of glyphicons inside two types of buttons by simply using a span inside the buttons...
It is known for a while that dealing with loops in Blade has been limited, as of 5.3 there is a variable called $loop available
@foreach($variables as $variable)
// Within here the `$loop` variable becomes available
// Current index, 0 based
$loop->index;
// Current ite...
There are many responsive scenarios where it's necessary to have column units exceeding 12 in a single .row element. This is known as column wrapping.
If more than 12 columns are placed within a single row, each group of
extra columns will, as one unit, wrap onto a new line.
For example, cons...
Typically, you will want to create your SimpleJdbcCalls in a Service.
This example assumes your procedure has a single output parameter that is a cursor; you will need to adjust your declareParameters to match your procedure.
