QR Generator for Internet Explorer

 | December 24, 2014 10:50 am

Each time while browsing the web I came along a phone number I’d like to call, I had to type it on my phone number-by-number carefully.
Therefore, I went for a search to find a working IE Search Provider (Accelerator) for generating QR codes to no avail.
So, I’ve decided to put together useful pieces I did found, and make my own.

Today I finally present a project me and my friend Mr Janko Jazbec are working on for the past two years. It is about cooling the attic of our house down. To read more about it, click here.

Shutting Down Linux Remotely

 | March 20, 2013 4:01 pm

I was looking for a way to automate remote Linux computer shutdown requiring minimum permissions. This is what I came up with.

The procedure describes how to configure and prepare Fedora’s built-in shutdown user account and trigger a shutdown from a Windows computer.

AD Authentication Failure after Reverting to Previous Snapshot

 | June 5, 2012 8:20 am

A successful configuration of Samba and Winbind allowing users to login to a Linux virtual computer using ones Active Directory credentials might stop working after a few weeks. If the virtual computer was reverted to previous snapshot between machine password changes in AD, the AD controllers will not let the computer authenticate again due to machine password mismatch.

Computing Block-wise Cross Correlation

 | April 12, 2011 4:42 pm

The cross correlation of two vectors using discrete Fourier transform (DFT) is a popular method of searching the occurrences of one pattern inside another. It provides simple mean to detect echoes, specific patterns inside digital signals, signal comparison etc.

In some applications, one of the input vectors (signals) is much longer than another, or even of infinite length. For example: searching a transmitted signal’s echo in the received input stream in radar or sonar, or detecting an RDS signal inside a continuous radio transmission. In such applications one must compute the cross correlation of searched pattern and input stream in a block-by-block manner.

In this article I shall present a short MATLAB template to compute a block-wise cross correlation appropriate for searching a specific pattern vector inside a continuous input vector of indefinite size. Furthermore, I shall extend the algorithm to search for more pattern vectors simultaneously.
