Windows 8 activation

Windows 8 is the new revolutionary operating system from Microsoft. I have been using it since the evaluation version. I found it pretty cool and user friendly. Some people might find it confusing at first, but when you get a hang of its new interface it is a breeze to work on.

Activating Windows 8 could be difficult. When trying to activate it in an enterprise where there is no license server (KMS Server), we get an error DNS name does not exist.

If, during installation one has not entered any product key, Windows gets registered with the default key. Unlike Windows 7, Windows 8 does not provide a direct interface to change the product key, so that you could use your genuine Windows 8 product key for activation.

The solution is to:
  1. Open an elevated command prompt (administrator mode)
  2. Run slmgr -upk - this would uninstall the existing product key. Now you can use your key.
After this step you may follow one of the following steps, as an administrator:
  1. Use the new Metro control panel (Win + C > Change PC Settings > Activate Windows)
  2. Run slui 3 or slui 4 for activation
  3. Run slmgr -ipk
Use the appropriate key, the one appropriate for your edition of Windows 8 and voila! Windows 8 is activated. Use genuine product and genuine product keys obtained from Microsoft.

Build Windows 8

Most of us are aware that Microsoft is promoting Windows 8 heavily. Windows 8 adoption is very important for the Redmond based company. Microsoft knows that developers play a very important role in this process. iOS developers have already proved this fact by writing Apple's success story.

Count and Label DNA strands

This is a proof of concept (POC) developed using Python3, NumPy, and OpenCV, to count and label the number of DNA strands from an image of combed DNA molecules.
The technique of Adaptive Mean Thresholding is used here.
There are several Thresholding algorithms available.
