This example is about deliberately ignoring or "squashing" exceptions. Or to be more precise, it is about how to catch and handle an exception in a way that ignores it. However, before we describe how to do this, we should first point out that squashing exceptions is generally not the co...
pip is your friend when you need to install any package from the plethora of choices available at the python package index (PyPI). pip is already installed if you're using Python 2 >= 2.7.9 or Python 3 >= 3.4 downloaded from python.org. For computers running Linux or another *nix with a native...

It is not possible to directly use static_cast, const_cast, dynamic_cast and reinterpret_cast on std::shared_ptr to retrieve a pointer sharing ownership with the pointer being passed as argument. Instead, the functions std::static_pointer_cast, std::const_pointer_cast, std::dynamic_pointer_cast and ...
Imagine you have all dates in all responses in some custom format, for instance /Date(1465935152)/ and you want apply general rule to deserialize all Json dates to java Date instances. In this case you need to implement custom Json Deserializer.
Example of json:
{
"id": 1,

Of the LINQ methods which use deferred execution, some require a single value to be evaluated at a time. The following code:
var lst = new List<int>() {3, 5, 1, 2};
var streamingQuery = lst.Select(x => {
Console.WriteLine(x);
return x;
});
foreach (var i in streamingQuery) {

Let's take a sample class.
class Book:
def __init__(self, title, author):
self.title = title
self.author = author
book1 = Book(title="Right Ho, Jeeves", author="P.G. Wodehouse")
In Python you can access the attribute title of the class using the dot ...
For the sake of data encapsulation, sometimes you want to have an attribute which value comes from other attributes or, in general, which value shall be computed at the moment. The standard way to deal with this situation is to create a method, called getter or a setter.
class Book:
def __init...
It is possible to use IO.inspect/1 as a tool to debug an elixir program.
defmodule MyModule do
def myfunction(argument_1, argument_2) do
IO.inspect(argument_1)
IO.inspect(argument_2)
end
end
It will print out argument_1 and argument_2 to the console. Since IO.inspect/1 returns i...

When a function doesn't preserve units automatically due to lower-level operations, the LanguagePrimitives module can be used to set units on the primitives that support them:
/// This cast preserves units, while changing the underlying type
let inline castDoubleToSingle (x : float<'u>) : fl...

String name
int age
}
def users = [

]
// sort by age
users.sort { a, b -> a.age <=> b.age }
If you don't have permissions to install perl modules, you may still install them manually, indicating a custom path where you've got writing permissions.
Fist, download and unzip module archive:
wget module.tar.gz
tar -xzf module.tar.gz
cd module
Then, if the module distribution contains a M...
All values in Rust have exactly one owner. The owner is responsible for dropping that value when it goes out of scope, and is the only one who may move the ownership of the value. The owner of a value may give away references to it by letting other pieces of code borrow that value. At any given time...
