Fighting WinSCP Time-Outs

That's a guide to making WinSCP send a dummy command every 30 seconds to keep your connection alive. It's way better than constantly having to type in your password.

Crontab Mistake

03 Sep 2013 I wanted to run a script every 20 minutes, so I put this into my crontab:
20 * * * * sh script.sh

That's wrong. That only runs it once every hour 20 minutes into the hour. For example, "20,40 * * * * sh bash.sh" would run it twice - 20 and 40 minutes into the hour.

To run the script every 20 minutes like I was expecting:
*/20 * * * * sh script.sh

Include yiiGridView Javascript

02 Sep 2013 http://chevronscode.com/yii-include-preload-yiigridview-javascript/

I ended up with the following code at the top of the page (since I'm not using a layout):

Yii::app()->clientScript->registerCoreScript('jquery');
$assetsScriptUrl = Yii::app()->getAssetManager()->publish(Yii::getPathOfAlias('zii.widgets.assets'));
Yii::app()->getClientScript()->registerScriptFile($assetsScriptUrl .'/gridview/jquery.yiigridview.js');

Memcache and Memcached are two different libraries.
There's a different (a small one) in speed between single and double quotes.
Use phpass to store passwords.

Set Up Wordpress For FTP

16 Aug 2013 If it's asking you for FTP login information when you try to update wordpress or a plugin, you don't need to do that! Chances are you don't have permissions correctly configured on that directory. Make sure apache owns the directory. On ubuntu, this will probably work (depending on which user owns apache):

sudo chown -R www-data:www-data /var/www

Bootstrap Span Is Overlapping

15 Aug 2013 Try setting a static width on the span. This ensures responsive knows when to put it on another line. It solved my issues with the spans overlapping.

example: add style="width: 520px" to your div with class="span6"
