Add New Mime Type to WordPress Multisite

In WordPress multisite there is a set of allowed file extensions that can be found at Settings>Network Settings in the “Upload File Types” field. You can add to this list but what isn’t necessarily apparent is that if the extension isn’t already part of the list here1 then you can add extensions all day and you’ll still get the security warning. To make a weird extension work . . . like .studio3 for instance you have to add the extension there and do a bit more. I tossed the following code in our network activated custom Rampages plugin. It’s just a hodgepodge of bits of code like this that I want applied across the site but that doesn’t seem like it deserves a plugin of its own. Take note that if you try to guess at the mime type and get it wrong, things won’t work. You’ll be able to select the file in the media uploader but it’ll still give you the security warning. I found this site for determining mime types. There may be other ways but it worked. 1 It is a generous list.

Facebook Loosening Up Privacy Restrictions

  Facebook is letting non-registered users find pictures and names of private accounts owners.  See link below for official Facebook statement and the page you need to keep your pic and name truly private. This would be good information to pass around to your colleagues.  Many teachers have Facebook accounts they have made private to keep prying students at bay.  This change would give the students access that most responsible teachers try to prevent. Link to Facebook’s explanation of  the privacy change Link to page where Facebook users can (again) restrict search access. via Lifehacker

Nightmare (guard your passwords)

An educational technology blog I followed out of Georgia (SEGA Tech) seems to have been abducted by a porn site. It’s possible the author has turned to the porn business but I kind of doubt it. A not so nice reminder to keep your passwords secure and your software/apps updated. That’d be quite a nightmare. It’d be all some people would need to outlaw school blogging forever or get you fired. I’d suggest going the passphrase route if at all possible. I’ve been using pass phrases when possible after reading this article. It’s kind of long but I’ve cut out the relevant chunk below. So here’s the deal – I don’t want you to use passwords, I want you to use pass-PHRASES. What is a pass-phrase you ask? Let’s take a look at some of my recent pass-phrases that I’ve used inside Microsoft for my ‘password’. “If we weren’t all crazy we would go insane“ (Jimmy Buffet rules) “Send the pain below!“ (I like Chevell too) “Mean people suck!“ (it’s true) So why are these pass-phrases so great? 1. They meet all password complexity requirements due to the use of upper / lowercase letters and punctuation (you don’t HAVE to use numbers to meet password complexity requirements) 2. They are so freaking easy for me to remember it’s not even […]
