clickjane.css: A CSS User Style Sheet to Help Detect and Avoid Clickjacking Attacks

Clickjacking or, more formally, user interface redressing, is a class of security vulnerabilities similar to phishing scams. The technique uses web standards to trick unsuspecting victims into performing actions they were not intending to. Clickjacking does not rely on bugs in any software. Instead, the technique is simply an abuse of the growing graphical capabilities […]

Why CSS needs delegation capabilities and not “variables”

It’s been too long since I joined the fun, if amazingly heated, debates over the direction that Web standards are moving in. Recently, given the “free” time to do so, I decided to dive head first into what is (sadly) an almost 14 year old debate. The result is this blog post, which is mostly […]

WP-Oomph: Add the Oomph Microformat Overlay to your WordPress blog

I’ve just developed a completely idiotic (by which I mean brain-dead simple) plugin for WordPress that will add the Oomph Microformat Toolkit to all WordPress-generated pages. If you use a WordPress template that encodes your data with valid microformats anywhere on your page, this means when you install the plugin your users will see the […]

Add a post limit and output format to the WordPress Category Posts plugin v2.0

This backwards-compatible patch features: parameter-based post limit to define how many posts the plugin function will print parameter-based format option to output the posts in real <li> elements The wp-category-posts.php patch file is available for download here.

Scrum-style Burn Down Chart in iWork ’08

Ever since I was introduced to the Scrum methodology of software development, I’ve enjoyed my work so much more than before. Most of that enjoyment is due to a sense of visibility, of knowing what’s going on. I find working without an accurate awareness of the situation at large very disorienting, and software and web […]

How to use mod_rewrite rules to easily enable web site “maintenance” modes

When you’re administering a web site, sometimes you need to make changes that for whatever reasons require that the web site be temporarily unavailable for normal visitors. One obvious example is database maintenance. Unless you have the resources to do full-blown load balancing across a server cluster, you probably have to accept that your site […]

How web designers can do their own HTML/CSS: Read Foundation Website Creation

Last month, 37signals published a short but sweet post about why web designers should do the HTML/CSS implementations for their own designs. The bottom line is, as we’ve all been saying for a long time now, that the Web is not the same kind of medium as other mediums like print. It is a fundamentally […]

Arbitrarily exclude posts from displaying in WordPress

When hacking away at WordPress sites, often times you’ll find yourself in a situation where you need to filter out certain posts from displaying on some pages, such as the home page. There are a lot of ways to do this, but few are perfect. Recently, I had the need to do this and went […]

I’m getting a book published and it’s called Foundation Website Creation

For those who have been wondering what is keeping me so busy these days, the answer is that I’m working on the final stages of a book that is getting published as one of three co-authors. Not only am contributing three chapters (the technical chapters on (X)HTML and CSS, specifically), but I am also technically […]

A web developer’s introduction to the Apple WikiServer (part 2)

Last time, we checked out the Apple WikiServer from the user’s side of things. We learned about the code it generates, how it handles page name changes, and what the key filesystem locations the Apple WikiServer looks at are. This time, let’s delve a little deeper into the WikiServer’s internals by (safely) messing around with […]
