Weak, Strong, Static And DynamicAn Introduction To Programming Type Systems

Static typing is great because it keeps you out of trouble. Dynamic typing is great because it gets out of your way and lets you get your work done faster. The debate between strongly and dynamically typed languages rages on, but understanding the issue starts with weak typing and languages such as C.

An Introduction To Programming Type Systems

C treats everything like a number. A character like a or 7 or % is the number of the ASCII symbol representing it; “true” and “false” are just 1 and 0. C defines variables with types such as int for integer and char for character, but that just defines how much memory to use. To access the variable and print it out, I need to know the type.

Web TypographySetting Weights And Styles With The @font-face Declaration

If people are on your website, they’re probably either skimming quickly, looking for something, or they’ve found what they’re looking for and want to read it as easily as possible. Either way, keeping text readable will help them achieve their goal.

Setting Weights And Styles With The @font-face Declaration

A few months ago, I wrote an article on “Avoiding Faux Weights and Styles with Google Web Fonts.” I ended the article by showing that weights and styles are an important UX element when setting text. Bold and italic forms of a font help people to skim your website.

Hex ColorsThe Code Side Of Color

The trouble with a color’s name is that it never really is perceived as the exact same color to two different individuals — especially if they have a stake in a website’s emotional impact. Name a color, and you’re most likely to give a misleading impression. Even something like “blue” is uncertain. To be more precise, it could be "sky blue", "ocean blue", "jeans blue" or even "arc welder blue".

The Code Side Of Color

Descriptions vary with personal taste and in context with other colors. We label them "indigo", "jade", "olive", "tangerine", "scarlet" or "cabaret". What exactly is "electric lime"? Names and precise shades vary — unless you’re a computer.

Review of JS FrameworksJourney Through The JavaScript MVC Jungle

When writing a web application from scratch, it’s easy to feel like we can get by simply by relying on a DOM manipulation library (like jQuery) and a handful of utility plugins. The problem with this is that it doesn’t take long to get lost in a nested pile of jQuery callbacks and DOM elements without any real structure in place for our applications.

Journey Through The JavaScript MVC Jungle

In short, we’re stuck with spaghetti code. Fortunately there are modern JavaScript frameworks that can assist with bringing structure and organization to our projects, improving how easily maintainable they are in the long-run.

Diving Into .NET Web Development

Many people think of PHP, Ruby on Rails or Python and Django when choosing a language to create a new website or when choosing a language to learn to get that exciting new job. .NET, however, seems to occupy a space somewhat apart from this playground of cool kids. It's always the last to be picked for team sports; it was shouting “Wassup!” at parties well after 2000; and it has been just plain left out in the cold.

I'm not one of these people. In fact, I'm quite a fan of .NET and have found it great to develop with since moving away from PHP in the early days of my career. With its great tools, large community and broad applicability (mobile, Xbox, desktop and Web) it's both powerful and fun.

CSS Sprites Revisited

I’m pretty confident that I won’t surprise anyone here by saying that CSS sprites have been around for quite a while now, rearing their somewhat controversial heads in the Web development sphere as early as 2003.

CSS Sprites Anno 2012

Still, the CSS sprite hasn’t truly found its way into the everyday toolkit of the common Web developer. While the theory behind CSS sprites is easy enough and its advantages are clear, they still prove to be too bothersome to implement, especially when time is short and deadlines are looming. Barriers exist to be breached, though, and we’re not going to let a couple of tiny bumps in the road spoil the greater perks of the CSS sprite.

WordPress Multisite: Practical Functions And Methods

Multisite is a powerful new feature that arrived with the release of WordPress 3.0. It allows website managers to host multiple independent websites with a single installation of WordPress. Although each “website” in a network is independent, there are many ways to share settings, code and content throughout the entire network.

WordPress Multisite: Practical Functions And Methods

Since the beginning of the year, I’ve been developing themes and plugins for a WordPress Multisite-powered content network. During that time I’ve learned many powerful tips and tricks unique to Multisite. This guide will introduce you to a few Multisite-specific functions, along with real-world programming examples that you can begin using today. Hopefully, it will open your eyes to a few of the new possibilities available in Multisite.

WordPress Essentials: The Definitive Guide To WordPress Hooks

If you’re into WordPress development, you can’t ignore hooks for long before you have to delve into them head on. Modifying WordPress core files is a big no-no, so whenever you want to change existing functionality or create new functionality, you will have to turn to hooks.

wp-hooks-guide

In this article, I would like to dispel some of the confusion around hooks, because not only are they the way to code in WordPress, but they also teach us a great design pattern for development in general. Explaining this in depth will take a bit of time, but bear with me: by the end, you’ll be able to jumble hooks around like a pro.

WordPress Essentials: How To Create A WordPress Plugin

WordPress plugins are PHP scripts that alter your website. The changes could be anything from the simplest tweak in the header to a more drastic makeover (such as changing how log-ins work, triggering emails to be sent, and much more).

Whereas themes modify the look of your website, plugins change how it functions. With plugins, you can create custom post types, add new tables to your database to track popular articles, automatically link your contents folder to a “CDN” server such as Amazon S3… you get the picture.

WordPress Essentials: Interacting With The WordPress Database

While many functions you already use in WordPress communicate with the database there is an easy and safe way to do this directly using the $wpdb class. Built on the great ezsql class by Justin Vincent, $wpdbwill allow you to address queries to any table in your database, and it will also help you handle the return data. Since this is built in WP functionality, there is no need to open a separate database connection (you would be duplicating code in this case), and there is no need to do hacks, like modifying a result set after it has been queried.

$wpdb class

In this article I will show you how to get started with the $wpdb class, how to retrieve data from your WordPress database and how to run more advanced queries which update or delete something in the db. The techniques here will remove some of the contraints that you run into with functions like get_posts() or wp_list_categories(), allowing you to tailor the queries you make to your specific needs. This method can also make your website more efficient by only getting the needed data, nothing more, nothing less.
