My partner is pregnant with my child. We were doing homework on the couch with her twelve year old daughter. All was going well when she started hitting her mother and then hit her mildly in the stomach.  I didn't react other than saying you shouldn't do that. I am concerned she might have hurt the fetus like that. The fetus is three and a half months old.  I am also concerned she might be doing that when I'm not there. My partner may not be saying anything to me to relieve the pressure.  Her daughter and son sometimes say they don't want this child we wanted.  What should I do, as a father?
I have a 2 year old son and another baby on the way. I just recently found out I'm pregnant but not sure how far just yet. My son rammed into my stomach like he is always doing but this time it made me start having small pains in my stomach. I rushed to the bathroom to make sure there wasn't any bleeding.  I'm concerned his rough play could hurt the fetus if it continues. How should I put a stop to it?
Traveling without paying lodging fees in America I want to travel around the East Coast without paying for lodging.  I'd be willing to sleep in my car or even pitch a tent somewhere. Is this a problem?  Legal?  I really want to get to the beach this season but I’m afraid that lodging will be out of my price range.  Specifically Maryland, Delaware, maybe New Jersey or Virginia. A little look through an etymology dictionary shows that the root is Latin gigas with adjective form gigant.  So in its derivation to English, why did the second "g" get retained in gigantic but was dropped from giant?  I have an inkling that the word giant may have travelled through French on its way to English, where it may have been pronounced "gee-yant" or "jee-yant" with a change to the second "g" that was then dropped when taken into English.  However, the "g" is retained as a hard "g" in gigantic. Efficiently select beginning and end of multiple contiguous ranges in Postgresql query I've got about a billion rows of data in a table with a name and an integer in the range 1-288.  For a given name, every int is unique, and not every possible integer in the range is present--so there are gaps.  This query generates an example case:  --what I have: SELECT * FROM ( VALUES ('foo', 2),               ('foo', 3),               ('foo', 4),               ('foo', 10),               ('foo', 11),               ('foo', 13),               ('bar', 1),               ('bar', 2),               ('bar', 3)      ) AS baz ("name", "int")   I'd like to generate a lookup table with a row for each name and sequence of contiguous integers.  Each such row would contain:  name   --  the value of the name column start  --  the first integer in the contiguous sequence end    --  the final value in the contiguous sequence span   --  end - start + 1  This query generates example output for the above example:  --what I need: SELECT *  FROM ( VALUES ('foo', 2, 4, 3),               ('foo', 10, 11, 2),               ('foo', 13, 13, 1),               ('bar', 1, 3, 3)      ) AS contiguous_ranges ("name", "start", "end", span)   Because I have so many rows, more efficient is better.  That said, I only have to run this query once, so it isn't an absolute requirement.  Thanks in advance!  Edit:  I should add that PL/pgSQL solutions are welcome (please explain any Fancy Tricks--I'm still new to PL/pgSQL). I need help!
