ts-node is an npm package which allows the user to run typescript files directly, without the need for precompilation using tsc. It also provides REPL. Install ts-node globally using npm install -g ts-node ts-node does not bundle typescript compiler, so you might need to install it. npm instal...

HTML5 defines some HTML attributes as boolean; a boolean can only be true or false. The specification simply states that the presence of a boolean attribute implies that the attribute is set to true. In example using a disabled attribute in the following example disables the button input element: &...

Using XHTML you should avoid methods such as document.write and innerHTML as they treat XML as text and do not properly serialize code; an id attribute in HTML is essentially dumped in to the DOM and the id attribute is not serialized which means when trying to reference to it with something such as...

Consider following directory structure to comply with best practices: [ProjectRoot] |---[app] | |---[resources] | routes.php |---[web] | |---[resources] | | |---[css] | | |---[img] | | |---[js] | .htaccess | index.ph...

This example shows a simple global definition of a complexType. The definition is considered global as it is a child of the xs:schema. Globally defined types can be used elsewhere in the schema. This is the most common form for declaring a global xs:complexType, it defines the child elements using ...

In this example we are creating a new xs:complexType (EmployeeType) based on an existing xs:complexType (PersonType). The construction of this is slightly more complicated. Because the base xs:complexType (PersonType) is considered to be complex (more about this below) we add the <xs:complexCon...

This is where things get a little tricky. We are now restricting an existing xs:complexType. Our SolidStateDriveType derives from HardDiskType but removes the spinUpTime attribute and the RotationSpeed element. Notice the approach for dealing with attributes and elements is different. To remove an ...

# Get two numbers from STDIN, separated by a newline, and output the result number1 = gets number2 = gets puts number1.to_i + number2.to_i ## run with: $ ruby a_plus_b.rb ## or: $ echo -e "1\n2" | ruby a_plus_b.rb

After installing the SDK, atlas-run-standalone starts a JIRA instance with the latest released version. atlas-run-standalone --product jira The instance is available http://localhost:2990/jira The created instance is for testing only. It provides an other directory structure as production insta...

It is possible to customize the JIRA version, the port or the context path. atlas-run-standalone --product jira --version 6.0 --http-port 1337 --context-path issues The JIRA 6 instance is available under http://localhost:1337/issues There are more parameters that can be set for running atlas-ru...

Failing to load a file The first possible error is failing to load the library. In that case an OSError is usually raised. This is either because the file doesn't exists (or can't be found by the OS): >>> cdll.LoadLibrary("foobar.so") Traceback (most recent call last): File &...

The most basic object is an int: >>> obj = ctypes.c_int(12) >>> obj c_long(12) Now, obj refers to a chunk of memory containing the value 12. That value can be accessed directly, and even modified: >>> obj.value 12 >>> obj.value = 13 >>> obj c_...

In some cases, a C function accepts a function pointer. As avid ctypes users, we would like to use those functions, and even pass python function as arguments. Let's define a function: >>> def max(x, y): return x if x >= y else y Now, that function takes two arguments and r...

Let's combine all of the examples above into one complex scenario: using libc's lfind function. For more details about the function, read the man page. I urge you to read it before going on. First, we'll define the proper prototypes: >>> compar_proto = CFUNCTYPE(c_int, POINTER(c_int), PO...

By convention elementFormDefault is always set to qualified, but lets look at what it actually does. First with elementFormDefault set to qualified. <?xml version="1.0" encoding="utf-8" ?> <!--Created with Liquid Studio 2017 (https://www.liquid-technologies.com)--&g...

The easiest way to run a local JIRA instance, is to install the SDK and run atlas-run-standalone For further details see Starting a local JIRA test instance Please note that this runs a local test instance and is not meant for production.

One of the simpler ways of implementing an authorization system is using the flask-login extension. The project's website contains a detailed and well-written quickstart, a shorter version of which is available in this example. General idea The extension exposes a set of functions used for: log...

Consider the following code to copy one file to another: import java.io.*; public class FileCopy { public static void main(String[] args) throws Exception { try (InputStream is = new FileInputStream(args[0]); OutputStream os = new FileOutputStream(args[1])) { ...
