Amazon -- Deliver docs to PC or MAC

I still do not understand why the option of sending personal docs to PC (or Mac) kindle is disabled, there a couple of workarounds:

Option 1)

PC, right click on the document and open it with Kindle.
Mac, open with Kindle.

Option 2)

Find "My Kindle Content" folder and drop your document there.
Linux command [find / -name 'My Kindle Content']

pymongo.errors.AutoReconnect: not master

Cause:

Our mongo DB hasn't replica set config.

Verify replica set:

Log into mongo shell and do "rs.conf()", if it comes with "null" then do the following:

cfg = {"_id" : "rpls","version" : 1,"members" : [{"_id" : 0,"host" : "127.0.0.1:27017"}]}

This will set your instance as master, as described here:

java.io.StreamCorruptedException: invalid stream header: 32303133

If it is associated to "Caused by: org.hibernate.type.SerializationException: could not deserialize", then check the type of the classes you are importing.

I mistakenly was importing:

• import java.security.Timestamp;

Instead of

• import java.sql.Timestamp;
