Ubuntu – gnome panels hanging randomly after using “Connect to Server” (gvfs)??

For ages I put up with random hangs and where some or all of my panels would stop responding, and completely rebooting was the only solution (killall gnome-panels wouldn’t unfreeze things either; all the hung panels disappear, but then nothing comes back in their place)… I knew it had something to do with connecting to […]

drupal with active directory (ldap)

Getting drupal authenticating logins against active directory can be intimidating, at first. I certainly felt that way. A few hints You will need PHP installed with the ldap extension. Use phpinfo(); to check if it’s there. Without that you can’t even begin. The ldap_integration module for drupal is fantastic, but the configuration is confusing if […]

Today I ran a poll on the NZWEBDEV email list, and asked members to indicate which server side languages they regularly use in their work.

drupal: inserting flash content (youtube videos) fails to display in IE

One of the drupal web sites I work on had a problem where any youtube video that was posted to the site failed to display on internet explorer. Any other browser worked fine. The code we were trying to insert was this: <object height=”350″ width=”425″ codebase=”http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0″ classid=”clsid:d27cdb6e-ae6d-11cf-96b8-444553540000″> <param name=”src” value=”http://www.youtube.com/v/l0aVaRrBYQE” /> <embed height=”350″ width=”425″ src=”http://www.youtube.com/v/l0aVaRrBYQE” […]

rails error: IOError: Couldn’t load the unicode tables for UTF8Handler (dump format error(0xb))

Argh I can’t believe how long it took for me to track this one down. No one else on the internet had reported the problem before, so trusty ole google was no help. So I’m putting this one out there, to help others. This error is caused when a file vendor/rails/activesupport/lib/active_support/values/unicode_tables.dat becomes corrupted. The easiest […]

asp.net: huge difference between DataView.Table and DataView.ToTable

Both DataView.Table and DataView.ToTable return a DataTable from a DataView. The difference is that .Table gives you the underlying data, with no changes from the dataview’s sorting or filtering. ToTable on the other hand, gives you the data in the dataview after filtering and sorting! This is the sort of thing I’ve come to expect […]

ruby gotcha: exec command

Surprisingly small amount of documentation on the net about this…. When using the exec command, don’t expect any of your ruby code after it to execute! This is because the command you run using exec replaces the currently executing script! Use the system command instead, or the “ trick

automatic iframe height

Placeholder

I’ve been forced to use an iframe in an app I’m developing, for long and boring reasons. One of the perennial problems that iframes presented was that their height needs to be specified upfront, and if the content within turned out to be too long then too bad; a nasty scroll bar would appear in […]
