What Chrome Predictive URLs Look Like on the Server

Awhile ago, I was confused by repetitive 404 “Not Found” errors in my server logs. The 404 requests look like someone is typing out various words, a few letters at a time. This post shows what these weird 404s look like from the server’s perspective, and then goes on to explain why they happen and […] Continue »

expose_php, Easter Eggs, and .htaccess

A reader recently brought to my attention a reported vulnerability on servers running PHP. It’s been known about for eons, but it’s new to me and it involves easter eggs in PHP so I thought it would be fun to share a quick post about what it is and how to prevent leakage of sensitive […] Continue »

Media Temple (dv) 4.0 Migration & Optimization

About a month ago, I received an email letting me know that my host, Media Temple, is discontinuing their (dv) Dedicated Virtual 3.0-3.5 servers. Everyone hosted on the old servers must migrate to the new (dv) 4.0 servers. The friendly (mt) email says: The migration is a fairly simple process and you’ll have until early […] Continue »

Notes on Switching Servers

Switching servers & migrating sites can be a HUGE deal (or not), depending on things like: Number of sites to transfer Size and complexity of sites Who is hosting your sites Experience I recently did this, switching from a 3-year run at ASO to my new home at Media Temple.

Find a Diamond in the Rough

However, you might know what type of web hosting you are looking to get but still do not know what provider to partner up with. Many of the web hosting top lists you find on the web […] Continue »

Yahoo! Slurp too Stupid to be a Robot

I really hate bad robots. When a web crawler, spider, bot — or whatever you want to call it — behaves in a way that is contrary to expected and/or accepted protocols, we say that the bot is acting suspiciously, behaving badly, or just acting stupid in general. Unfortunately, there are thousands — if not […] Continue »

Yahoo! Lies about Obeying Robots.txt Directives

There are two possibilities here: Yahoo!’s Slurp crawler is broken or Yahoo! lies about obeying Robots directives. Either case isn’t good. Slurp just can’t seem to keep its nose out of my private business. And, as I’ve discussed before, this happens all the time. Here are the two most recent offenses, as recorded in the […] Continue »

Evil Incarnate, but Easily Blocked

As my readers know, I spend a lot of time digging through error logs, preventing attacks, and reporting results. Occasionally, some moron will pull a stunt that deserves exposure, public humiliation, and banishment. There is certainly no lack of this type of nonsense, as many of you are well-aware. 3G Blacklist Even so, I have […] Continue »

Yahoo! Once Again Caught Disobeying Robots.txt Rules

Hmmm.. Let’s see here. Google can do it. MSN/Live can do it. Even Ask can do it. So why oh why can’t Yahoo’s grubby Slurp crawler manage to adhere to robots.txt crawl directives? Just when I thought Yahoo! finally figured it out, I discover more Slurp tracks in my Blackhole trap for bad spiders: Continue »

I need your help! I am losing my mind trying to solve another baffling mystery. For the past three or four months, I have been recording many 404 Errors generated from msnbot, Yahoo-Slurp, and other spider crawls. These errors result from invalid requests for URLs containing query strings such as the following: https://example.com/press/page/2/?tag=spam https://example.com/press/page/3/?tag=code https://example.com/press/page/2/?tag=email https://example.com/press/page/2/?tag=xhtml […] Continue »

Improve Site Performance by Increasing PHP Memory for WordPress

During the recent ASO server debacle, I raced frantically to restore functionality to Perishable Press. Along the way, one of the many tricks that I tried while trying to fix the dreaded “white screen of death” syndrome involved increasing the amount of PHP memory available to WordPress. This fix worked for me, but may not […] Continue »

Quickly Disable or Enable All WordPress Plugins via the Database

Recently, while dealing with the dreaded white screen of death, I found myself unable to login to the WordPress Admin area to manually disable all of the plugins used here at Perishable Press. In the past, I have dealt with this situation by simply deleting all plugin files from the server, however this time, time […] Continue »

Perishable Press Upgraded to WordPress 2.3.3

Just a note to announce a site upgrade to WordPress 2.3.3. The upgrade went well, but overall server performance continues to suffer.
