How to Modify HTTP Headers in the WordPress Admin Area

Vanilla JavaScript Smooth Scroll
While working on the site’s 24th redesign, my goal was to simplify the UI as much as possible. As much as I enjoy lots of cool effects, I wanted the new design to be as minimalist as possible. So that meant dropping a LOT of little bells and whistles that were included in the previous design. One feature that didn’t make the cut was smooth scrolling to internal anchor targets. Like when you click a link that takes you #somewhere […] Continue reading »

I’m seeing a big increase in bot attacks targeting theme files directly. First they get the URL to your theme directory. There are numerous ways for a bot to get this information. For example most themes include assets like CSS and JavaScript files, and the link includes the full URL.

Requesting template files directly may reveal possible […] Continue reading »

Difference between mod_alias and mod_rewrite
Most of the redirect techniques provided in my stupid .htaccess tricks article all use Apache’s alias module, mod_alias. You can also use mod_rewrite to redirect URLs. The main difference is that, with mod_alias, the server is responding to the client request with a redirect, so the client immediately is sent to the new location. Conversely, with mod_rewrite, the server simply returns the new content, so the client is not actually redirected anywhere. This makes mod_rewrite more advantageous because it happens […] Continue reading »
CLI Forward-Reverse Lookup

This is often referred to as a forward-reverse lookup, or something to that effect. The point is, there are plenty of free online tools available for performing forward-reverse IP/host lookups. And online tools are great, but it’s also possible to do forward/reverse lookups directly via the command line, […] Continue reading »
