Automatically enable plugins in new WordPress Multisite blogs
View auto-activate-plugins.php
// There are three options (that I know of) for automatically enabling a plugin
// in new sites.
// 1. Move the plugin from wp-content/plugins/ to wp-content/mu-plugins/ (MU =
// Must Use). But then it cannot be deactivated for any site.
// 2. Click "Network Activate" instead of "Activate" to enable it for all sites.
// I didn't want to use this though because I didn't want to affect existing

HTML to PDF conversion in PHP using wkhtmltopdf (and optionally Smarty)

Recently I was asked to generate PDF invoices for an online shop. I looked at various PHP PDF generators, but wasn't particularly impressed with any of them.

Then I found (via Stack Overflow) a command-line HTML-to-PDF convertor called wkhtmltopdf, which uses WebKit (the same layout engine as Safari and Google Chrome) and therefore is very accurate.

There is a class for PHP integration on the Wiki, but I found it overly complicated and it uses temp files which aren't necessary. This is the code I wrote instead.

I used Smarty for generating the HTML for the PDF, but you can use any template engine, or pure PHP if you prefer.

Note: I originally tried to install wkhtmltopdf from source, but it's much easier to use the static binary instead.

Turn monitor off with a keyboard shortcut with AutoHotKey
View monitor-off.ahk
; This is part of my AutoHotkey [1] script that turns off my monitor when I
; press Win+\.
; It also turns the screensaver on at the same time, so that Windows Live

; I don't have a password on my screensaver, so there is a second version

Sleep/suspend/hibernate computer with a keyboard shortcut using AutoHotKey
View sleep.ahk
; This is part of my AutoHotkey [1] script that puts my computer to sleep when I

; I don't have my PC set to require a password to resume, so I also have a
; second version (Win+Shift+F12) in case I want to lock the PC first.

Set WordPress site URL in the config file instead of the database
View wp-config.php
// WordPress stores the site URL in the database by default (which I have never
// understood), and it's a pain to have to type out the UPDATE SQL or search in
// phpMyAdmin to change it. This is a simple way to put the URL into
// wp-config.php instead.
// Note that you will still need to update any URLs that appear in the content,
// especially when you copy a database from a development site to production:
You can’t perform that action at this time.
