Blockchain, learning about the basis

I have started to read about this topic and I cannot stop reading articles and things related to it. I am starting from the basis to understand the concepts and how all this will change the paradigm of our lives.

I have started with this book:

La-economia-de-blockchain It’s in Spanish and they do a good review of the theory of blockchain and examples to understand the finance and technical basis. Then there is a good review of the applications that we have today in the market. If you are reading the book after 2016, it’s clear the application landscape can be so much different.

Bike-a-thon Bridge to the Beach

Last Sunday I participated on this ride organized by ACS (American Cancer Society).

Between the route and the road to home we did 120 kms, which is not a bad distance with the temperature and the humidity we had.

The route itself has interesting parts with nice views and some others that are a little bit boring. The nicer side is all the people riding together and people with bells supporting the riders. PHL-AC-Bike-a-thon

(Start line in the Benjamin Franklin bridge at 6.30)

Date formats in excel

Just for my memory,

Just in USA the date format is mm/dd/yyyy, the rest of the world uses dd/mm/yyyy. Anyway…

I have excels where I have both formats inherited from links, so I cannot change the source data.

The solution:

=IF(ISNUMBER(Q202);Q202;DATE(RIGHT(Q202;4);LEFT(Q202;FIND(“/”;Q202)-1);MID(Q202;FIND( “/”;Q202 )+1;2)))
