The function chomp will remove one newline character, if present, from each scalar passed to it. chomp will mutate the original string and will return the number of characters removed my $str = "Hello World\n\n"; my $removed = chomp($str); print $str; # "Hello World\n" pr...

To use multiple databases in Django, just specify each one in settings.py: DATABASES = { 'default': { 'NAME': 'app_data', 'ENGINE': 'django.db.backends.postgresql', 'USER': 'django_db_user', 'PASSWORD': os.environ['LOCAL_DB_PASSWORD'] }, 'users': {...

The normal obj.save() method will use the default database, or if a database router is used, it will use the database as specified in db_for_write. You can override it by using: obj.save(using='other_db') obj.delete(using='other_db') Similarly, for reading: MyModel.objects.using('other_db').al...

Ansible uses the concept of roles to better allow modular code and avoid repeating yourself. A role is simply a folder structure that Ansible knows where to load vars files, tasks and handlers from. An example might look something like this: apache/ ├── defaults │   └── main.yml ├── files │   ...

Roles also enable you to define other roles as a dependency by creating a meta/main.yml file with a dependencies block: dependencies: - role: common It's also possible to pass a value to a parameter/variable in the dependent role: dependencies: - { role: common, some_parameter: 3 } Or ...

It's also possible to easily share roles with the community or download roles that have been created by other members of the community with Ansible Galaxy. Ansible ships with a command line tool called ansible-galaxy that can be used to install roles in the role directory defined in the ansible.cfg...

class Digit { public Digit(double d) { val = d; } public double val; // User-defined conversion from Digit to double public static implicit operator double(Digit d) { Console.WriteLine("Digit to double implict conversion called"); return d.val;...

Above I noticed an example to remove items from a List within a Loop and I thought of another example that may come in handy this time using the Iterator interface. This is a demonstration of a trick that might come in handy when dealing with duplicate items in lists that you want to get rid of. N...

Use a singular name for most Enums public enum Volume { Low, Medium, High } Use a plural name for Enum types that are bit fields [Flags] public enum MyColors { Yellow = 1, Green = 2, Red = 4, Blue = 8 } Note: Always add the FlagsAttribute to a bit field E...

The left-shift operator (<<) can be used in flag enum declarations to ensure that each flag has exactly one 1 in binary representation, as flags should. This also helps to improve readability of large enums with plenty of flags in them. [Flags] public enum MyEnum { None = 0, Fl...

For testing our application, I'm using advance rest client which is chrome extension: So, here is the snapshot for inserting the data:

A Intersection Type combines the member of two or more types. interface Knife { cut(); } interface BottleOpener{ openBottle(); } interface Screwdriver{ turnScrew(); } type SwissArmyKnife = Knife & BottleOpener & Screwdriver; function use(tool: SwissArmyKnife){ ...

Multiple FOR clauses are allowed in a LOOP. The loop finishes when the first of these clauses finishes: (loop for a in '(1 2 3 4 5) for b in '(a b c) collect (list a b)) ;; Evaluates to: ((1 a) (2 b) (3 c)) Other clauses that determine if the loop should continue can be combined: ...

The special LOOP NAMED foo syntax allows you to create a loop that you can exit early from. The exit is performed using return-from, and can be used from within nested loops. The following uses a nested loop to look for a complex number in a 2D array: (loop named top for x from 0 below (arr...
