Recent Drama, News, and Other Stuff

Okay so it’s been awhile. That’s a good thing because it means I’m busy. But it also sucks because life moves too fast to blog about everything that happens. Especially with web design: you get started blogging about your discoveries, and then you find yourself learning and doing too much to post or tweet about […] Continue »

HTTP Headers for ZIP File Downloads

You know when you you’re working on a project and get stuck on something, so you scour the Web for solutions only to find that everyone else seems to be experiencing the exact same thing.

Latest Blacklist Entries

Recently cleared several megabytes of log files, detecting patterns, recording anomalies, and blacklisting gross offenders. Gonna break it down into three sections: User Agents Character Strings IP Addresses User Agents User-agents come and go, and are easily spoofed, but it’s worth a few lines of htaccess to block the more persistent bots that repeatedly scan […] Continue »

Importing WordPress Users via CSV Files

I recently did some time in Microsoft Excel, preparing large CSV files for import into WordPress. Each of these CSV files contained data for 1000 WordPress users.

When designing a website, it’s always a good idea to test on as many different platforms, devices, and browsers as possible. These days, pimping your websites for the iPhone and iPad is an important step in the design process. Especially on the iPad, sites tend to look about 20% cooler than on desktop browsers, so […] Continue »

How to Deal with Content Scrapers

Chris Coyier of CSS-Tricks recently declared that people should do “nothing” in response to other sites scraping their content. I totally get what Chris is saying here. He is basically saying that the original source of content is better than scrapers because: it’s on a domain with more trust. you published that article first. it’s […] Continue »

Country, Regional, and State Abbreviations

Creating dropdown menus for web forms is such a fun way to spend the afternoon. One of the funnest things for me is adding all of the regional, state, and country codes when they’re required. Here are a few lists to make my web-dev life a little easier. Here’s a quick jump menu: Country and […] Continue »

I have written tons of web development stuff at Perishable Press, lots of helpful WordPress stuff at Digging into WordPress, some creative/artistic stuff at Dead Letter Art, jQuery stuff at jQuery Mix, and some business-related web-design stuff at Monzilla Media. Plus a bunch of interviews, guest posts, […] Continue »

The 2010 User-Agent Blacklist blocks hundreds of bad bots while ensuring open-access for the major search engines: Google, Bing, Ask, Yahoo, et al. Blocking bad user-agents is an effective addition to any security strategy. It works like this: your site is getting hammered by rogue bots that waste valuable server resources and bandwidth. So you […] Continue »

Best Method for Email Obfuscation?

Awhile ago, Silvan Mühlemann conducted a 1.5 year experiment whereby different approaches to email obfuscation were tested for effectiveness. Nine different methods were implemented, with each test account receiving anywhere from 1800 to zero spam emails. Here is an excerpt from the article: When displaying an e-mail address on a website you obviously want to […] Continue »

Protect Your Site with a Blackhole for Bad Bots

One of my favorite security measures here at Perishable Press is the site’s virtual Blackhole trap for bad bots. The concept is simple: include a hidden link to a robots.txt-forbidden directory somewhere on your pages. Bots that ignore or disobey your robots rules will crawl the link and fall into the honeypot trap, which then […] Continue »

htaccess Code for WordPress Multisite

For the upcoming Digging into WordPress update for WordPress 3.0, I have been working with WordPress’ multisite functionality. Prior to version 3.0, WordPress came in two flavors: “original” and “multisite” (MU). Most designers probably work with regular, one-blog installations of “regular” WordPress. The htaccess rules for all single-blog installations of WordPress haven’t changed. They are […] Continue »

2010 IP Blacklist

Over the course of each year, I blacklist a considerable number of individual IP addresses. Every day, Perishable Press is hit with countless numbers of spammers, scrapers, crackers and all sorts of other hapless turds. Weekly examinations of my site’s error logs enable me to filter through the chaff and cherry-pick only the most heinous, […] Continue »
