This example shows multiple producers and consumers sharing the same buffer. Protected entries in Ada implement a queue to handle waiting tasks. The default queuing policy is First In First Out. ------------------------------------------------------------------ -- Multiple producers and consumers ...
Controller (Pages.php) public function contact() { $this->load->library('email'); $this->load->library('form_validation'); //Set form validation $this->form_validation->set_rules('name', 'Name', 'trim|required|min_length[4]|max_length[16]'); $this...
To include the base64 module in your script, you must import it first: import base64 The base64 encode and decode functions both require a bytes-like object. To get our string into bytes, we must encode it using Python's built in encode function. Most commonly, the UTF-8 encoding is used, howeve...
The base64 module also includes encoding and decoding functions for Base32. These functions are very similar to the Base64 functions: import base64 # Creating a string s = "Hello World!" # Encoding the string into bytes b = s.encode("UTF-8") # Base32 Encode the bytes e = b...
The base64 module also includes encoding and decoding functions for Base16. Base 16 is most commonly referred to as hexadecimal. These functions are very similar to the both the Base64 and Base32 functions: import base64 # Creating a string s = "Hello World!" # Encoding the string into...
Adobe created it's own encoding called ASCII85 which is similar to Base85, but has its differences. This encoding is used frequently in Adobe PDF files. These functions were released in Python version 3.4. Otherwise, the functions base64.a85encode() and base64.a85encode() are similar to the previous...
Just like the Base64, Base32, and Base16 functions, the Base85 encoding and decoding functions are base64.b85encode() and base64.b85decode(): import base64 # Creating a string s = "Hello World!" # Encoding the string into bytes b = s.encode("UTF-8") # Base85 Encode the byte...
Understanding the concept To understand content negotiation in Web API, it is important to understand the term Resource. On the web, any information that we can access can be referred as HTTP resource. There is a tremendous amount of material to view on the web which has different content type suc...
The traditional GLSL compilation model involves compiling code for a shader stage into a shader object, then linking multiple shader objects (covering all of the stages you want to use) into a single program object. Since 4.2, program objects can be created that have only one shader stage. This met...
If Errorlevel 1 ( Echo Errorlevel is 1 or higher REM The phrase "1 or higher" is used because If Errorlevel 1 statement means: REM If %Errorlevel% GEQ 1 REM Not If %Errorlevel% EQU 1 ) ...
Naturally, being able to install hard drive cloning utilities can be an important aspect of installing and maintaining your operating system. Getting set up with Clonezilla is surprisingly less straightforward than I'd have expected. The wealth of options, while valuable, also makes each part of id...
This example will be using the class md-icon-button, which must be applied to <md-button> in order to get an icon button. It is also recommended to add an aria-label attribute to <md-button> for accessibility purpose or the ARIA provider will throw a warning that there is no aria-labe...
The continue statement in Objective-C programming language works somewhat like the break statement. Instead of forcing termination, however, continue forces the next iteration of the loop to take place, skipping any code in between. For the for loop, continue statement causes the conditional test a...
Our openstack tenant is already set: a virtual lan gives instances private IP a virtual router map public IP to private IP a security key has been generated we have default firewall configuration for ssh and port 80 we are able to launch an instance thanks to the OpenStack web interface ...
Bullet This one particularly blew my mind. The bullet gem helps you kill all the N+1 queries, as well as unnecessarily eager loaded relations. Once you install it and start visiting various routes in development, alert boxes with warnings indicating database queries that need to be optimized will p...
The color schemes changes the colors of the code. They can change, for example, with which color the keywords are highlighted, with which color the line the caret is on is highlighted (needs highlight_line to be set to true in the preferences (not part of the cojor scheme)), what is the color of the...
GTM simplifies the whole process of managing tags.In GTM terminology We put a GTM javascript snippet on the concerned page,in portal_normal.vm in custom theme in liferay, containing the GTM id and a data layer structure(if needed) to map values from page to variables Corresponding to data layer ...
This is a unit test of a component that has Store as a dependency. Here, we are creating a new class called MockStore that is injected into our component instead of the usual Store. import { Injectable } from '@angular/core'; import { TestBed, async} from '@angular/core/testing'; import { AppComp...
This is a unit test of a component that has Store as a dependency. Here, we are able to use a store with the default "initial state" while preventing it from actually dispatching actions when store.dispatch() is called. import {TestBed, async} from '@angular/core/testing'; import {AppCom...
There are cases when you need to change Display Name of column in a list view e.g. Column Name showing in the view is "IsApprovalNeeded" and you want to appear as "Is Approval Needed?". You can, of course change the display name of a column by changing the column title in list ...
