marriage planning

Well, it is difficult. I suggest to have an exhaustive manual and things that you may need.

Here is the list that I think is required

  1. Medicines
  2. Toiletry/Cosmetics
  3. Basket for snacks
  4. List of phone numbers of all active persons (friends, relatives and employees)
  5. Plans for each persons with date and time using google calendar and google drive.
Some steps I have taken is as follows

  1. Placing bulk order with Easy Day/Apollo/Mother Dairy and telling them to deliver material quickly on demand that we forget / have additional needs.
Will be sharing the docs and the experience and the mistakes after the event.

Visit to UIET @ Kurukshetra

I was invited by Mr Rahul Gupta of UIET to present Industry designs on Oct 19th.

I presented about what I do to M Tech students and B Tech students. While students and Mr Gupta was very passionate and enthusiastic, their course and existing knowledge was too obsolete. I shared two kits of PT60 controller from freescale with Aseem Bansal and one more student.

Here is the copy of presentation.

Which Controller to Use and Why?

I have worked on various controllers and processors - starting  from 8080 and 8048. Technology keeps improving with time and next design is always better in performance, speed, on board peripherals and usually lowers in cost. Also software tools keeps improving.

As on Aug 2012 - I am working on Arduino and STM8 for 8 bits, PIC32 for 32 bits and STM32F4 for Arm Cortex M4 and Raspberry Pi for embedded Linux based designs. The reason is easy availability of devices, low cost tools, better support and of course excellent tools with built in libraries.

Today, I do not focus on hardware but on software tools. New software tools with built in libraries offer reduce time to market. Of course, I do not understand every thing about the product. Well, I do not need to as my target is to deliver product and not the library.

Only if you need to develop library, you need to go thru the internal and details of device.

See the comments of various design professionals in Aug 2012 issue of EFY.

Why I do not need vacations or how I keep blood pressure below 120/80

I was with my doctor today to get treatment for hair root infection. He checked my BP - it was 118/70. He complimented me on keeping same BP for last 15 years, even when as a true Punjabi, I enjoy lot of butter and pakoras ....

Well, here is what I do to keep low blood pressure and does not look forward to vacations or even a weekend -
  1. I work for 12 hours a day X 7 days a week on thing that I enjoy and make money.
  2. get royal welcome from maggie and a good smile from Geeta on reaching home, 
  3. spend three hours every week with saksham kids and see their smile and excitement. Spend some money and get lot of fun and enjoyment.
  4. get up in the morning when  maggie's starts licking my face, Spend 45 minutes in park walking and listening to the birds. 
  5. Have a library with books on Psychology, Management, Fiction, Sex and Religion. Spend more time and money on books than on TV.
  6. And live a life that I love.

Try it out and you may find that enjoying every day life is more addictive than any thing else you are addicted to ........
