Software and hardware prerequisites for installation of BizTalk Server (All versions) Software requirements 1. Development environment Below software tools are required for BizTalk environment, not all of them are needed, but having all might add some advantage for developing BizTalk applications...

A Haskell's Functor allows one to map any type a (an object of Hask) to a type F a and also map a function a -> b (a morphism of Hask) to a function with type F a -> F b. This corresponds to a Category Theory definition in a sense that functor preserves basic category structure. A monoidal ca...

Usually this means that the Master crashed and that sync_binlog was OFF. The solution is to CHANGE MASTER to POS=0 of the next binlog file (see the Master) on the Slave. The cause: The Master sends replication items to the Slave before flushing to its binlog (when sync_binlog=OFF). If the Master cr...

1067 This is probably related to TIMESTAMP defaults, which have changed over time. See TIMESTAMP defaults in the Dates & Times page. (which does not exist yet) 1292/1366 DOUBLE/Integer Check for letters or other syntax errors. Check that the columns align; perhaps you think you are putting i...

In some cases basic validation is not enough. Angular support custom validation adding validator functions to the $validators object on the ngModelController: angular.module('app', []) .directive('myValidator', function() { return { // element must have ng-model attribute // o...

An integer type whose value can be either true or false. bool is_even(int x) { return x%2 == 0; } const bool b = is_even(47); // false

There are a few common symbols in use: copyright sign ©, and trademark signs ® ™ fractions like ¼ superscripts. For instance, a shorthand for square meters is m².

fork() is a system call. fork is used to create a child process from the running process, which is a replica of the parent process(Process which executed fork() ). Child process is derived from the parent process. Both the parent and child have different address space, each is independent of the cha...

If you want to set some alias name to installed node version, do: nvm alias <name> <version> Similary to unalias, do: nvm unalias <name> A proper usecase would be, if you want to set some other version than stable version as default alias. default aliased versions are loade...

In this example we create a new list element with the text "new text", and select the first unordered list, and its first list element. let newElement = document.createElement("li"); newElement.innerHTML = "new text"; let parentElement = document.querySelector(&quo...

An element can be removed by calling remove() on it. Alternatively, one can call removeChild() on its parent. removeChild() has better browser support than remove(). element.remove(); element, and all its childnodes, are removed from the DOM. parentElement.removeChild(element); element...

There are several ways of getting the data that you will bind to the DOM elements. The simpler one is having your data in your script as an array... var data = [ ... ]; But D3.js allows us to load data from an external file. In this example, we will see how to properly load and deal with data fr...

You can create ACL by using Phalcon\Acl\Adapter\Memory class: $acl = new Phalcon\Acl\Adapter\Memory(); By default phalcon allows action to resource which has not been defined, to change this you can use: $acl->setDefaultAction(Phalcon\Acl::DENY); Roles can be added in two ways - using Pha...

You can allow role to access some action on resource by: $acl->allow('Administrator', 'products', 'create'); You can deny role to access some action on resource by: $acl->deny('Customer', 'categories', 'create'); You can check if role is allowed to some action on resource by using: $a...

You can add also add some more logic which has to be checked to your ACL using anonymous functions. They will be executed when using Phalcon\Acl\Adapter\Memory::allow() or Phalcon\Acl\Adapter\Memory::deny(), if they will return true, they role will be allowed to access certain action on resource. $...

By implementing Phalcon\Acl\RoleAware or Phalcon\Acl\ResourceAware you can use them as objects in Phalcon\Acl\Adapter\Memory::isAllowed(). // Create our class which will be used as roleName class UserRole implements Phalcon\Acl\RoleAware { protected $id; protected $roleName; publ...
