Scollector can be used to monitor processes and services in Windows and Linux. Some processes like IIS application pools are monitored automatically, but usually you need to specify which processes and services you want to monitor.

A FrameLayout with a rounded corner background and shadow. CardView uses elevation property on Lollipop for shadows and falls back to a custom emulated shadow implementation on older platforms. Due to expensive nature of rounded corner clipping, on platforms before Lollipop, CardView does not clip...

There are also several other FOR XML modes: FOR XML RAW - Creates one <row> element per row. FOR XML AUTO - Attempts to heuristically autogenerate a hierarchy. FOR XML EXPLICIT - Provides more control over the shape of the XML, but is more cumbersome than FOR XML PATH.

Bitwise operations alter binary strings at the bit level. These operations are incredibly basic and are directly supported by the processor. These few operations are necessary in working with device drivers, low-level graphics, cryptography, and network communications. This section provides useful k...

[[ -OP $filename ]] [[ $file1 -OP $file2 ]] [[ -z $string ]] [[ -n $string ]] [[ "$string1" == "$string2" ]] [[ "$string1" == $pattern ]] The [[ … ]] syntax surrounds bash built-in conditional expressions. Note that spaces are required on either side of th...

Maps are data types used for storing unordered key-value pairs, so that looking up the value associated to a given key is very efficient. Keys are unique. The underlying data structure grows as needed to accommodate new elements, so the programmer does not need to worry about memory management. They...

NSArray *words; // Declaring immutable array NSMutableArray *words; // Declaring mutable array NSArray *words = [NSArray arrayWithObjects: @"one", @"two", nil]; // Array initialization syntax NSArray *words = @[@"list", @"of", @"words", ...

SomeClass sc = new SomeClass { Property1 = value1, Property2 = value2, ... }; SomeClass sc = new SomeClass(param1, param2, ...) { Property1 = value1, Property2 = value2, ... } The constructor parentheses can only be omitted if the type being instantiated has a default (parameterless) const...

Some times you need to create extended text documentation from you xml comments. Unfortunatly there is no standard way for it. But there are some separate projects that you can use for this case: Sandcastle Docu NDoc DocFX

Build a named capture group (X being the pattern you want to capture): (?'name'X) (?X) (?PX) Reference a named capture group: ${name} \{name} g\{name} Python and Java don't allow multiple groups to use the same name.

This topic outlines how and when the Swift runtime shall allocate memory for application data structures, and when that memory shall be reclaimed. By default, the memory backing class instances is managed through reference counting. The structures are always passed through copying. To opt out of th...

shift shifts the positional parameters to the left so that $2 becomes $1, $3 becomes $2 and so forth. "$@" is an array of all the positional parameters passed to the script/function. "$*" is an string composed of all the positional parameters passed to the script/function. ...

A swarm is a number of Docker Engines (or nodes) that deploy services collectively. Swarm is used to distribute processing across many physical, virtual or cloud machines. Initialize a swarm: docker swarm init [OPTIONS] Join a swarm as a node and/or manager: docker swarm join [OPTIONS]...

Foldable is the class of types t :: * -> * which admit a folding operation. A fold aggregates the elements of a structure in a well-defined order, using a combining function. If t is Foldable it means that for any value t a we know how to access all of the elements of a from "inside&qu...

The Traversable class generalises the function formerly known as mapM :: Monad m => (a -> m b) -> [a] -> m [b] to work with Applicative effects over structures other than lists.
