Iris Recognition–Identity & Authentication through Biometrics

Image
I did some research at the technology lab at the Purdue University West Lafayette Campus in 2004 and wrote this paper: Poets have romanticized the eyes over centuries. The beauty of the eyes has been voiced through civilizations. Many songs have been written about them, all aspects of the eyes have been glamorized. The Egyptians ceremoniously decorated the eyes, the Hindus apply kajal to highlight the eye contours, and the western civilizations called eyes the window to the soul. Researchers today look at the eyes with from a different perspective. One such researcher is Richard P. Wildes. He looks at human eyes to identify people. The biometric based technology is called iris recognition. It is suggested that the iris is as distinct as a fingerprint or the patterns of retinal blood vessel. In the 1997 article, Wildes investigates the iris relative to uniqueness and identification. He explains the structure of the eye and what makes the iris unique and identifiable with repeatability....

COTS or FOSS for Emerging Economies

Image
Introduction I do not agree with any position that suggests open source software is an attractive option for emerging technologies. Although emerging economies may choose to adopt open source software, the primary driver for that adoption is not free software. The cost differential of open source alternatives to available commercial alternatives is not significant enough to affect national economies or drive decision of corporations in those economies. In this paper I explore the definition of open source software, its primary drivers for adoption in industry and the open source business model. I hypothesize that open source software is a collaborative software development model that owes its success to quality, security, openness and extensibility but not low price alone. Also, I augment to the hypothesis: open source is not targeted for emerging economies or markets alone; rather open source is targeted at the whole world and any adopter. Open Source and the Internet T...

Windows 8 – For Programmers

Image
I installed the Windows 8 32-bit operating system on my 5 year old T61 with 4GB RAM. I upgraded it from Windows XP that I had for a couple years because I could not use Ubuntu anymore due to Netflix and iTunes not being interoperable. The Live Tiles may be ok for a tablet with touch screen – but it is not good for programmers who are usually “keyboarders”. You can of course disable Metro: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer : RPEnabled=0 will disable it. However, I wanted to see if I could continue to use Metro and still have the speed and resource utilization of XP. So the first thing I did was “optimize for performance” – this can be done from My Computer>Properties>Advanced .. > Performance Next, I made the Windows key my friend. So Hitting the Windows Key gets you in in and out of tiles much faster than a “swipe” of the mouse etc.   Windows 8 Keyboard Shortcuts http://howto.cnet.com/8301-11310_39-57390299-285/23-new-keyboard-...

Learning to let Employees Lead

Image
I was give this book to read by my manager several years ago, and since then I have read a lot of books on team leadership etc. This book was one of the simpler reads. To summarize this book, the authors take an approach that is akin to the live and learn approach, learn by your mistakes approach, and a generalize by personal experience approach. I wrote in 2006 : Belasco and Stayer have written an oddly titled best-selling book in first person based on these principles of leadership. Flight of the buffalo (FOTB ) is a joint venture that dives head first into experiences of running companies, heuristics of leadership, visual analogies, gut feel, earthly common sense and best practices of "leadership". The oddity of the title is explained early in the book. The book begins with the authors' journeys into leadership and various related concepts & ideas. Amongst others ideas like intellectual capitalism, leadership vision, focus, direction, obstacles (removing them...
