• Rob Gruhl - How to Buy a New Car

  Sander August 13, 2015 at 12:11 pm

  From 2007, but a great video full of advice, and a fantastic example of pechakucha 20x20 presentation style.

  The ad policy is what is costing publishers millions of dollars - the ad blockers are what keep the readership from leaving the site!

• Windows 10 Privacy Guide

  Sander August 6, 2015 at 9:45 am

  Steve Gibson pointed me to a guide to setting your desired privacy level in Windows 10. This version of Microsoft's operating system follows the 'always socially connected' footsteps of smartphones and therefore makes privacy assumptions. Using this guide you can check if they match your expectations.

• Automatic crash reporting using FogBugz for PowerShell

  Sander August 3, 2015 at 3:24 pm

  This morning I integrated our PowerShell processes into FogBugz by writing a small module that submits occurrences of all errors to BugzScout. You might want to do something similar so I did this write-up.

  Broadly it works similar to BugzScoutLogWriter that I developed previously for integration with SilverStripe CMS. In this case however, we need to do the following things:

  1. Set the script to stop on all errors so they can be trapped instead of ending the execution of the script.
  2. Capture the error details and submit them to FogBugz
  3. Have an error occur. ;)

  I've published the code in a Gist for you a have a look. I include the function in every script I use.

  If your blog is more of a reference than a diary, why do you organise your posts in a timeline? Instead group them by category.

• Hide Trackbacks works with WordPress 4.2

  Sander July 23, 2015 at 12:08 pm

  Hide Trackbacks is a WordPress plugin that hides pingbacks and trackbacks from your website comments.

  I've updated the plugin to indicate it works correctly with WordPress 4.2.

  Let's all turn off on-site commenting, and allow replies via moderated trackback. Anyone can start a blog and participate with increased civility and ownership. DONE.

• Enum label lookup

  Sander July 23, 2015 at 11:27 am

  In your datamodel you might have a Enum field such as this date-based dropdown:

  public static $db = array(
      "Year"        => "Enum('2013, 2014, 2015')"
  }
  

  Internally, SilverStripe stores the index, so that when you retrieve the value in methods such as onBeforeWrite, instead of 2013 you will receive 1. Use the function below to retrieve the label of the Enum:

  public function EnumLabel($field_name) {
      $enumValues = $this->dbObject($field_name)->enumValues();
      $label    = $enumValues[$this->$field_name];
      return $label;
  }
  
  // $year = $this->EnumLabel('Year');

• LessThanOrEqual in SilverStripe 3.0

  Sander July 23, 2015 at 11:24 am

  When adding a filter on a DataList sometimes you need to do a <= rather than a <. Unfortunately the LessThanOrEqual and GreatherThanOrEqual search filters do not exist in SilverStripe 3.0.x, they were added in 3.1.

  Therefore we have to write our own where clause like the following example:

  // Return all the sessions on or before the $date
  $sessions = new DataList('AcademicSession');
  $sessions = $sessions->where('"SessionStartDate" <= \'' . $date . '\'');
