Posted on April 14, 2014August 20, 2018 by ellen

BBEdit’s Grep Search is a very handy tool for cleaning long text files. I recently had to move a form from a webpage into Qualtrics. In the original form there is a list of about

Movable Type: How to emulate an MTEntryIfNotExtended tag

Posted on June 20, 2013November 19, 2013 by ellen

Movable Type has a built in container tag

<MTEntryIfExtended>

which is often used to show the “More” part of a long entry, or anything else that should be displayed only if the entry is extended:

<MTEntryIfExtended> <$MTEntryMore$> <div>Special text or page elements for Extended Entries go here</div> </MTEntryIfExtended>

But what if you want something to show up only if the entry is NOT extended? There is no corresponding <MTEntryIfNotExtended> tag.

Fortunately that functionality is simple to replicate using Movable Type variables.

WordPress: SimpleLDAP plugin updated to work with v3.5

Posted on June 8, 2013November 19, 2013 by ellen

The SimpleLDAP plugin by Cliff Griffin is exactly what I needed for a proof-of-concept WordPress site I’m working on, but it hasn’t been officially updated in a while and was not entirely compatible with WordPress v.3.5.

I’ve updated the plugin to eliminate the errors I was getting, and it now works fine on my site, but it could probably use some TLC from someone more experienced with working with WordPress.

The original version of the plugin I used as a basis is v1.4.0.5.1, available at http://wordpress.org/plugins/simple-ldap-login/.

Use BBEdit to replace the entire contents of multiple files

Posted on June 20, 2012 by ellenm1

A few months ago, I needed to revise an HTML file that is used many times across a large website. Most of the key code associated with this file is contained in centrally-located includes, but as luck would have it, this time the entire file needed to be revised – even the user-customized bits. That meant that almost a thousand files would have to be replaced. Worse, they were not entirely the same, since they were customized by the users to some extent.

After checking a few of them, I found there were enough commonalities to serve as the basis of a regular expression search. They always started with a comment, like this:

.htaccess tricks Allow public access to a subdirectory

Posted on January 7, 2011 by ellen

I run a little site that is mostly access-protected. If it is viewed from a location within the company IP, no password is needed. If viewed from outside the company firewall, it will ask for a user-id and password. However we wanted to make one subdirectory public.

JW FLV player with Javascript playlist

Posted on December 15, 2009 by ellen

This is an example of how to create a javascript-based Playlist selector for a JW FLV player. The playlist selector menu has 3 sections that toggle open and closed when you click on them. This allows the user to switch playlists, choosing from various topics.

The source code has not been cleaned up, but you should be able to get an idea of how to set this up from it.

.htaccess: allow anyone from one IP but require password from everywhere else

Posted on November 28, 2009 by ellen

If you want your linux-hosted site to be accessible by anyone coming from a particular IP address, as say from within a corporate firewall, but also accessible from anywhere else as long as they authenticate with username and password, use this formula in the .htaccess file for the directory:

#this section may need to be modified to suit your password authentication setup:
AuthUserFile "/home/pathTo/.htpasswds/directory_name/passwd"
AuthType Basic
AuthName "webroot"
require valid-user
# allow users from inside firewall
Allow from 111.222.33
Satisfy Any

JW FLV Player and Red5 apparent buffering bug

Posted on October 27, 2009 by ellen

Update 12-18-09: Longtailvideo has apparently resolved this bug with its player v.4.7beta. At this time v. 5 does NOT have the fix in it. The code changes that fixed the bug can be seen here: [Changes to RTMPModel.as]

A few months ago, we installed Red5 0.7.0 on a Windows server to stream Flash video inside the firewall. This server is used mainly to stream short clips that are embedded in learning modules.

The JW FLV player v. 4.6 is included in the learning module template and enables us to display the videos with a high degree of flexibility.

Example of a player that contains multiple short video clips.
The player generates a navigation listing on the right from the XML playlist.
