And All It's Friends...
I’m not personally huge on modifying or getting my IDE to do lots of bells and whistles, but simply having a central program and place to debug, test, compile, and write your code is very powerful for your productivity. Add on that basic code inspection tools, error checking, syntax highlighting, file tracking, version control, and you got yourself a tool I’d use any day.
You will find some individuals who consider whether a language is usually interpreted or compiled split languages into these categories. However, the truth of the matter is quite the opposite. Whether a language is compiled or interpreted is actually an independent choice from the nature of the language itself. Any language can be interpreted by what is known as an interpreter, or compiled by what is known as a compiler.
asherwunk/phabstractic now implements a common event object, useful in the “Universal Event System”. The Universal Event System What I call the universal event system is basically several constructs built on top of the Publisher/Observer design...
I decided that, for future projects, I needed to port asherwunk/phabstractic to the Python programming language (pyabstractic). Well, phabstractic relies on a couple packages itself that are in the PHP domain. One of these packages is zend-config, which is part of the Zend Framework programming library.
Besides this failing however, I believe this book does a fabulous job of getting anyone with a background in programming up and running with Redis in as short a time as possible. But there’s the catch, it assumes you have a background in programming and that you are proficient at the types of things that Redis is used for.
Observers and Publisher design patterns are very important in that they enable a certain amount of reactive programming. When you only want something to execute or occur when a particular event occurs it makes more sense to just test for state change then to hard code in an if clause for every step.
Doubly linked lists are important data structures for they enable a range of data to be stored in sequential order in memory without necessarily having to be spaced next to each other, or worry about a particular size. There are many advantages to storing data outside of an array like this, including the dynamic nature of its allocation and flexibility of editing the order of elements (including the addition and subtraction of elements).
Object stores, associative arrays, and Maps are important data structures. They are useful in statistical analysis, as well as for in memory database storage, such as a Redis implementation. The advantage of a map is that you don’t have to remember cryptic index values, as well it allows you to establish an abstract association between two data objects.
It’s not too hard to set up a basic command line PHP coding environment using github, composer, and phpunit. This tutorial covered how to set up the development environment if you’re using php purely from the command line. This tutorial did not cover *AMP installations.
Priority Queues are very useful and usually, are implemented using heaps. This Priority Queue is implemented using an array that sorts itself rather than an overly complicated binary tree or heap. A priority queue is very useful for event-oriented programming, multitasking processes, and online message queues.
Self-sorting lists can be very handy. For instance, we could easily implement a priority queue by utilizing a sorted list, and that’s something we’re going to do, simply using the comparison method on competing priorities. Self-sorting arrays make putting everything in order in a messaging queue fairly simple.
Lists are very important pieces of software engineering and implementation. With a restrictions predicate we are able to ensure variables in PHP are specific types. If we combine these two things we get a restricted list.
“In computer science, a stack is an abstract data type that serves as a collection of elements, with two principal operations: push, which adds an element to the collection, and pop, which removes the most recently added element that was not yet removed.”
Queues are very important pieces of code. They are used in numerous many places including web services, transactions, and multi-process operating systems.
Lists are very important abstract data types, and are used in many many different applications. Stacks are often used with programming languages, and in fact some programming languages depend entirely on a stack, such as Postscript.
By combining the restrictions predicate and the set we are able to configure a Set that only holds certain objects and types. This means I can make a set of integers, or a set of nodes, or a set of whatever without fear that the set will hold anything else.
The abstract factory pattern provides a way to encapsulate a group of individual factories that have a common theme without specifying their concrete classes.
Many programming techniques and data structures – including rope (data structure), lazy evaluation, class hierarchy (see below), arbitrary-precision arithmetic, CDR coding, the indirection bit and other kinds of tagged pointers, etc. – are usually implemented using some sort of tagged union.
Filters are important and very useful objects, allowing values or other logic to be filtered in and out of a particular set of data. Restrictions.php offers a way to use type checking in PHP, but in a very flexible and dynamic way. This can be useful for defining lists or sets that only accept certain values, which is useful for code cohesiveness and can reduce error checking.
Sets are very important mathematical constructions, and enable the computation of many other abstract data types. A set can have singularly exclusive values, or can have multiples of the same value in them. Sets can be compared using algebraic operators, and can exist as subsets of other sets. Set abstract data types can hold references as the data of an element, enabling some interesting behavior.
