Solving technology problems, one at a time
Occasionally when re-publishing my whole site after modifying the templates, I get this error:

When installing Plupload module to work with Media module on a Hostgator site, I got the error:
Your server is capable of displaying file upload progress, but does not have the required libraries. It is recommended to install the PECL uploadprogress library (preferred) or to install APC.
Looking at the suggested library (pecl.php.net) it was a shell script that pretty obviously required privileges that I would not have on a shared host. However, Hostgator has another library already installed that implements PECL: CodeGen_PECL. It just has to be enabled.

I had occasion to make a patch file the other day, and since I do this so rarely, it took some time to look up how to do it. So here, in a nutshell is how to use diff on a Mac.
Open terminal.
At the prompt, type
diff -up newfile oldfile
But really the easiest way to get the paths right is to type:
diff -up
…then drag first the new file, then the old file from the desktop onto the terminal window right at the end of the line after -up . It will fill in the paths for you.
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/.

When I re-installed CTools (Chaos Tools Suite) during a Drupal 7 upgrade, it resulted in this error: Failed: PDOException: SQLSTATE[23000]: Integrity constraint violation: 1062 Duplicate entry ’29’ According to this post, it may have something

Working with Drupal 7, you may get an error like the one below. (The actual number may be different.)
Fatal error: Allowed memory size of 52428800 bytes exhausted
If you don’t have one already, add a text file called “php.ini” to the root directory of the Drupal 7 site, and add a line like:
memory_limit = 96M
or

I recently had to move a .NET application directory to a new location on an IIS 6 server. When I did, of course everything broke. Among the errors that had to be fixed was this one:
Unrecognized attribute 'targetFramework'.
This is usually because the application pool is not set to use the framework assigned to the application in IIS Manager.
There are several ways to fix this. I chose the easiest one: setting the application extension path to the correct executable.

I work in a small learning management department in a large Health System. One of the “forever” problems we’d like to solve, is how to get out of the way of our many clinical subject matter experts and make it EASY for them to put trackable learning content online by themselves. Why is this still a problem in this age of online applications? Simply put: cost, learning curve and trackability.
Licensing costs in a decentralized environment
Software license costs are a big issue in a distributed authoring environment, particularly for departments that watch every penny. There are hundreds of potential authors out there, mostly in departments that do not prioritize the purchase of elearning software. Licenses for the big elearning software packages (Articulate, Storyline, Lectora, etc.) are not inexpensive, even with academic discounts and whatever site-licenses may exist.
While experimenting with LDAP connections in Safari, errors like this one started popping up:
“The website _____ requires a client certificate”
A dialog would open, listing some old MobileMe certificates. Apparently if any old, expired or corrupt MobileMe certificates are still lodged in the Keychain, you may get this error sometimes. MobileMe has been disabled and signed out on my Mac for years, but the fact that the certs were still there caused the problem.

I’ve been experimenting with LDAP and Cosign login plugins for WordPress. Most of them are out of date and are more or less incompatible with WordPress v.3.5. Usually the first error that comes up is
Notice: has_cap was called with an argument that is deprecated since version 2.0!
All this means is that instead of using the numerical role identifier argument in a function that adds a menu or submenu, the required capability should be used instead.
