Learn the Way of WordPress

It’s been quiet around here, but I have a good excuse. I spent the last six months writing, designing, and publishing my third book, The Tao of WordPress. This is an excellent book for beginners, students, designers, and basically anyone who wants to learn how to get the most from WordPress. The book “soft-launched” last week, and now I want to share the news with readers here at Perishable Press. Continue reading »

New Design in Progress

My new book is doing well, so I have some time to work on my sites. Here at Perishable Press, I’ll be working on a redesign, refreshing some older content, and posting some new articles. Continue reading »

Set Up WordPress MultiSite on MAMP

In this tutorial, you’ll learn how to install and run WordPress MultiSite on a MAMP webserver. Running multiple sites from a single installation simplifies and streamlines administration, and serving it all from a locally installed version of MAMP gives you everything you need to develop your network of sites for the Web.

Run WordPress Locally with _AMP

To run WordPress on the Web, you need a domain name and web host. But you don’t need either of those things to run WordPress on your own computer. You need only to set up a local server environment that includes Apache, MySQL, and PHP. That may sound like a tall order, but thanks to packaged software bundles such as MAMP and WAMP, setting up a robust server environment on your computer is a relative breeze. Continue reading »

WP-Mix – A fresh mix of code snippets and tutorials

Wrapping up 2012, I finally launched xyCSS, which is all about responsive, grid-based design. To showcase xy.css, I used it to design WP-Mix.com, which also serves to house a growing collection of choice code snippets. Currently WP-Mix features over 100 snippets, tutorials, and other useful bits to help with WordPress development and web design in general. The topics are similar to those at Perishable Press (e.g., WordPress, PHP, JavaScript, CSS, etc.), but the posts are less-involved and aimed at intermediate […] Continue reading »

xy.css – Responsive Grid Design

For the past year or so, I’ve been heavy into responsive, grid-based design. In December, I “soft-launched” my new site, xyCSS with a simple tweet: Bringing it all together: https://perishablepress.com/xycss/ As implied (and explained), xy.css is a lightweight CSS template for creating semantic HTML5 designs on a responsive liquid matrix.

5G Blacklist 2013

Following up on much feedback (and this post), here is an update for the 5G Blacklist for 2013. As explained in the 2012 article (and elsewhere), the 5G Blacklist helps reduce the number of malicious URL requests that hit your website. It’s one of many ways to improve the security of your site and protect against evil exploits, bad requests, and other nefarious garbage. If your site runs on Apache and you’re familiar with .htaccess, the 5G is an effective […] Continue reading »

Introspection WordPress Theme

Free WordPress theme! The dark/minimalist design of the Introspection theme was originally created for a Pink Floyd fan site. After taking the site down to clear room (and time) for new stuff, I felt the design was too sweet to just let rot away in the archives. So after a few days of generalizing Introspection for public use, I’ve made it freely available for download so it can shine on.. Continue reading »

Protection for WordPress Pingback Vulnerability

It was recently reported about a WordPress Pingback Vulnerability, whereby an attacker has four potential ways to cause harm via xmlrpc.php, which is the file included in WordPress for XML-RPC Support (e.g., “pingbacks”). In this post, I offer a simple .htaccess technique to lock things down and protect against any meddling via the xmlrpc.php file. Continue reading »

(Please) Stop Using Unsafe Characters in URLs

Just as there are specifications for designing with CSS, HTML, and JavaScript, there are specifications for working with URIs/URLs. The Internet Engineering Task Force (IETF) clearly defines these specifications in RFC 3986: Uniform Resource Identifier (URI): Generic Syntax. Within that document, there are guidelines regarding which characters may be used safely within URIs. This post summarizes the information, and encourages developers to understand and implement accordingly. Continue reading »

Printed .htaccess books

After launching my new book .htaccess made easy back in September, I wanted to allow time to fix any errors or typos before sending the book to the printers. After a couple of months, I had updated the book three times with better code, new techniques, and design improvements. After a few final steps to optimize for print format, the books were ordered, printed and delivered fresh on Christmas Eve :) So to celebrate the event, all printed .htaccess books […] Continue reading »

What I did in 2012

It’s been an amazing year across the board. Here is a quick recap of some of the things I did in 2012. I don’t keep a journal of every little detail, but here are some of the things I remember specifically setting out to do, sort of organized by month. So much more to report, these are just the highlights. Continue reading »

Blacklist Candidate 2012-11-13: Evil Scanner Edition

It’s been awhile since I’ve posted one of my Blacklist Candidate series articles. It’s always fun for me to talk (or write) about security related issues, especially when a quick slab of .htaccess can be used to take care of business. And that’s exactly what we have in this edition of the series, where I’m pleased to bring you Blacklist Candidate Number 2012-11-13: the “evil” scanner. Instead of scanning your site, collecting data, and moving on, Mr. 2012-11-13 continues to […] Continue reading »

SAC Pro: Unlimited chats.
Thoughts
I disabled AI in Google search results. It was making me lazy.
Went out walking today and soaked up some sunshine. It felt good.
I have an original box/packaging for 2010 iMac if anyone wants it free let me know.
Always ask AI to cite its sources. Also: “The Web” is not a valid answer.
All free plugins updated and ready for WP 6.6 dropping next week. Pro plugin updates in the works also complete :)
99% of video thumbnail/previews are pure cringe. Goofy faces = Clickbait.
RIP ICQ
