Click to play for plugins (Flash, Java) in Firefox

In Google Chrome, there is an option to enable “Click to Play” for plugins, such as Flash, Java, or Silverlight. This makes the browser safer (especially after all the Java security vulnerability in the last time) and a little bit fast. Today, I found out that this option exists in Firefox too – although its a little bit hidden.

To enable “Click to Play” in Firefox…

  1. go to about:config and click on “I’ll be careful, I promise!”
  2. search for plugins.click_to_play and set it to true (by double-clicking the entry)


After that, when you get to a page that contains Flash (videos), Java, or any other plugin, you’ll get a “Click to Play” message for the plugin.


Plotting graphs with R

This post is about how to display (draw) a mathematical function with R.

Side note: There’s a very nice and interactive tutorial for R available over at It’s free and takes about 3 – 4 hours to complete.

Bug of the day: Sorting in Windows Server Backup

For me, Windows Server Backup (2012) is actually a huge bug itself. Just have a look at my backup history:


Best of all: Every failure gives a nice cryptic error message (without any details), like:

  • “There was a failure in creating a directory on the backup storage location.”
  • “None of the items included in backup were backed up.”
  • “The specified component was not reported by the VSS writer.”

So far, I haven’t been able to get a reliable backup via Windows Server Backup.

So, until I get this fixed, let’s start with something light:


Take a good look on how the dates are sorted. Nice, isn’t it?
