Add the following code to functions.php to remove it from everyone except the Administrator user level: add_action('after_setup_theme', 'no_admin_bar'); function no_admin_bar() { if (!current_user_can('administrator') && !is_admin()) { show_admin_bar(false); ...

A less known builtin feature is Controller Action injection using the FromServicesAttribute. [HttpGet] public async Task<IActionResult> GetAllAsync([FromServices]IProductService products) { return Ok(await products.GetAllAsync()); } An important note is that the [FromServices] c...

The intent attribute of a dummy argument in a subroutine or function declares its intended use. The syntax is either one of intent(IN) intent(OUT) intent(INOUT) For example, consider this function: real function f(x) real, intent(IN) :: x f = x*x end function The intent(IN) specif...

It is possible to create custom routing constraint which can be used inside routes to constraint a parameter to specific values or pattern. This constrain will match a typical culture/locale pattern, like en-US, de-DE, zh-CHT, zh-Hant. public class LocaleConstraint : IRouteConstraint { pri...

Suppose we want to count how many counties are there in Texas: var counties = dbContext.States.Single(s => s.Code == "tx").Counties.Count(); The query is correct, but inefficient. States.Single(…) loads a state from the database. Next, Counties loads all 254 counties with all of the...

A linked list is a linear collection of data elements, called nodes, which are linked to other node(s) by means of a "pointer." Below is a singly linked list with a head reference. ┌─────────┬─────────┐ ┌─────────┬─────────┐ HEAD ──▶│ data │"pointer"│──▶...

Step 1: Install the SDK You can install the SDK manually or via CocoaPods. The latter option is highly recommended. Put these lines in Podfile: target 'MyApp' do use_frameworks! pod 'FBSDKCoreKit' pod 'FBSDKLoginKit' pod 'FBSDKShareKit' end Run pod install in the terminal and op...

from struct import pack print(pack('I3c', 123, b'a', b'b', b'c')) # b'{\x00\x00\x00abc'

Having a button there is all well and good, but what's the point if clicking it does nothing? ActionListeners are used to tell your button, or other component to do something when it is activated. Adding ActionListeners is done as such. buttonA.addActionListener(new ActionListener() { @Overri...

Fix takes a "template" type and ties the recursive knot, layering the template like a lasagne. newtype Fix f = Fix { unFix :: f (Fix f) } Inside a Fix f we find a layer of the template f. To fill in f's parameter, Fix f plugs in itself. So when you look inside the template f you find a...

Compare the definition of Free to that of Fix: data Free f a = Return a | Free (f (Free f a)) newtype Fix f = Fix { unFix :: f (Fix f) } In particular, compare the type of the Free constructor with the type of the Fix constructor. Free layers up a functor just like Fix, except ...

A string can be used as a separator to join a list of strings together into a single string using the join() method. For example you can create a string where each element in a list is separated by a space. >>> " ".join(["once","upon","a","tim...

Gradle has the ability to add a wrapper to projects. This wrapper alleviates the need for all users or continuous integration systems to have Gradle installed. It also prevents version issues where there is some incompatibility between the version the project uses and that which users have installed...

From Apple documentation: Use the CTCallCenter class to obtain a list of current cellular calls, and to respond to state changes for calls such as from a dialing state to a connected state. Such state changes are known as cellular call events. The purpose of CTCallCenter is to give the develop...

RoboGuice is a framework that brings the simplicity and ease of Dependency Injection to Android, using Google's own Guice library. RoboGuice 3 slims down your application code. Less code means fewer opportunities for bugs. It also makes your code easier to follow -- no longer is your code littered ...

This is useful to see if there are any non-printable characters, or non-ASCII characters. e.g. If you have copy-pasted the code from web, you may have quotes like ” instead of standard ". $ cat -v file.txt $ cat -vE file.txt # Useful in detecting trailing spaces. e.g. $ echo '” ' | c...

All collection objects contain a map method that takes a Function as an argument, which must take a single argument. This returns an Iterable backed by the collection. When the Iterable is iterated, each step calls the function with a new element of the collection, and the result of the call becomes...

Although it's bad practice, it's possible to add multiple return statements in a exception handling block: public static int returnTest(int number){ try{ if(number%2 == 0) throw new Exception("Exception thrown"); else return x; } catch(Exception e){ ...
