Was just trying to make a Python 2 script work in Python 3 and at first it seemed I just needed a small change to add missing parentheses to the argument of a couple of print statements.

In ClipFlair Studio I use DotNetZip (Ionic.Zip) library for storing components (like the activity and its nested child components) to ZIP archives (.clipflair or .clipflair.zip files). Inside the ZIP archive its child components have their own .clipflair.zip file and so on (so that you could even nest activities at any depth) which construct their ...

To fix it, from a command prompt with administrator rights (Start/Find, type Command and right ...

XAF’ security system is really flexible and can easily address complex scenarios.

This will be a detailed discussion on all the steps involved in doing so. In addition a sample application is ...

At ClipFlair’s Image component I use the following XAML to make it show an image from a URL that its ViewModel holds at a property named “Source”, of type Uri (URI = Uniform or Universal Resource Identifier in W3C parlance, something like a superset of the old classic URLs). <Image Name="imgContent"        ...

While stepping through “ShowDialog()” method of OpenFileDialog with Visual Studio 2010 debugger, at the Silverlight code pictured below (for loading a ClipFlair window’s stored options), I got a “Dialogs must be user-initiated” exception.

Supposing you have an MSDN Subscription, you could download say SQL Server 2012 Standard Edition (x86 and x64) – DVD (English) from the following URL: http://msdn.microsoft.com/en-us/subscriptions/downloads/hh442898.aspx#FileId=48810 Suppose you do so and you keep that .ISO file (a CD/DVD image that you can burn to a disk using Windows 7 or ...

Babylon Search is one of the most abusive addons for Mozilla Firefox and other web browsers. It installs with other free software (most probably profiting from tracking your searching habits) and then it is quite hard even for experienced users to completely uninstall it. While maintaining other computers in the past I’ve used a combination [...]

A reader of my recent article on a page faking YouTube design to lure you into subscribing for a pay-per-message you receive scheme for mobile phones, told me that they came across a very similar one by typing wikipdia.org instead of Wikipedia.org.

While I was trying to visit twitter I suddenly was faced with this page, which although very well designed looked immediately suspicious to me, first of all because of the redirects I noticed happening at the address bar and also because the landing URL was using the word “rewardz”.

Would be nice to have a GUI wrapper around [...]
