Biography of Sri Hiriannaiah

I read the following biography of Sri Hiriannaiah at http://rajchat.info/vasudeva_kutumbukam/7_two_exemplary_officerst.html. Sri Hiriannaiah also belonged to Bobburkamme sect and most probably our family is related to his family, exactly how I don't know but may learn in the future. What was interesting is the propensity of descendants of Sri Kalappa to pursue law and serve in justice profession. The entire biography is copied from the above source. " Sakleshpur Hirianniah (S.

My MOOC Progress

I finished my first MOOC course "Introduction to Mathematical Thinking" taught by Keith Devlin of Stanford, an outstanding professor. It was a tough course! I am almost half done with "Introduction to Genetics and Evolution" taught Mohammed Noor, another outstanding professor from Duke. I have already learned a great deal from this course. This is a tough course too. Believe it or not, I have signed up another 16 MOOCs! Within a month, three courses will be starting; Think Again: How to Reason and Argue , Introduction to Astronomy , Drugs and the Brain .  The New York Times called 2012, the year of the MOOCs, see http://www.nytimes.com/2012/11/04/education/edlife/massive-open-online-courses-are-multiplying-at-a-rapid-pace.html?pagewanted=all&_r=1&.

401K, 403B Rollover into an IRA

I am trying to gather info on the IRA rollover. I am piecing together info I found on the web. 1. Can I Use an IRA Rollover to Move Funds Out of My Company Retirement Plan While I Still Work There? Probably not. Most company retirement plans do not allow you to roll funds out of the plan while you are still employed. To find out if they do, you can call your plan sponsor, and ask if they allow what is called an "in-service distribution". Does AT&T allow? Does TIAA/CREF allow? An in-service distribution is a different type of transaction than a loan or hardship withdrawal. An in-service distribution is a transaction where you can rollover a portion of funds in your plan into a self-directed IRA account while you are still employed. Only some plans allow this. No Longer Employed Once you are no longer employed, it may make sense to roll funds from your plan into an IRA account. At that time, to avoid tax withholding, you'll want to choo...
