What is an Integrated Development Environment (IDE)?

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.

What Is A Linker?

Linkers are essential pieces of the software development process and allow programmers to separate out their code in meaninful ways.  They also allow the use of programming libraries, code that has been generated to be used by other programs.  The C Standard Library is an example of such a library, allowing standard C programs to link to its code to perform such operations as general input/output.  If we did not have a linker in our compilation process we’d have to write all our programs as one giant monolithic file.

Memory Map of an Imperative Program on Most Processors

This isn’t THEE only memory map of every program everywhere, but it is generally the memory map for most programs most average programmers create, being imperative.  In programming languages like assembly or C, you work with this map pretty directly, but in more abstract or higher-level languages such as Python or PHP, many of these memory issues and placements are taken care of for you by the interpreter or compiler.

Interpretation Versus Compilation

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.

The Nature of the C Programming Language

In this article we cover the C programming language: where did it come from, how it relates to other languages, what can it do, what doesn’t it do, and the future of the language. C is a powerful language any aspiring programmer would benefit from learning and mastering. Even today, in embedded systems, C is very much employed, and in that personal respect, important to building my robot.

Programming Language Crash Course (Bootstrap Part 1)

With variables, data types, flow control, functions, expressions, statements, subroutines, and such under your belt, you are prepared to understand more fully just about any programming that comes your way from any of the popular general purpose languages out there.  That’s really the core of what makes up programming today (granted you’re not using a more specialized language such as Prolog or LISP).

Announcing PYGJS (PyGame in your Browser/NodeWebkit)

That’s right, run PyGame (in all it’s Pythonic glory) IN THE BROWSER! All in all, it’s a rough draft.  The code isn’t fully documented because really, it’s ported from other places where there IS documentation (pygame, gamejs, etc.)  Anywhere where the functions/classes don’t QUITE act like their pygame equivalent I make a note of though, so that you aren’t tripped up.

HTTP Explained: The HyperText Transfer Protocol, Part 1

We’ve covered the basic concepts of HTTP and the types of information that it deals with. We dealt with the parts of an HTTP request on a high level, all the different request types, and some of the other basic features and ideas of the HTTP (protocol).

Anatomy of a URI (What is a URL, URN, etc.?)

With URIs we can reference and locate just about everything we need to on the internet, from books, videos, sites, and games. Without URIs we’d still be stuck in specific clunky ways to access specific things using specific clients and methods, instructions which I followed in many a book before URIs became a big thing. Now, it’s simple: http://wunk.me/

Book Review: Writing Compilers And Interpreters

I came across this book in the Colorado State University library, one of my favorite places, and was intrigued.  I was intrigued because it seemed that instead of relying on esoteric computational equations and such, talking about optimization, O notations, and such, this book instead took the approach of diving directly into straight implementation of a compiler and interpreter.

Phabstractic: Generic Event (Universal Event System)

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...

Objconfig (Python): Config Class

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.

Phabstractic: Observer/Publisher Design Pattern

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.

Phabstractic: Linked List Data Type

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).

Phabstractic: Map Data Type

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.

Doing Stuff With Computers

The primary processor is the user, who is directing the computer and its activities, but the primary computational device is called the CPU (central processing unit) and is a chip on the motherboard of the computer.

Setting Up A Local GitHub Hosted PHP Project on OS X

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.

Phabstractic: Priority Queue Data Type

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.

Remembering Things With Computers

So we’ve learned about binary and boolean operations along with logic gates. None of these, particularly logic gates, can do the second most important thing necessary for computation.

That is the ability to remember.

Phabstractic: Self-Sorting List Data Type

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.
