When it's undesirable for the sewer line to extend below the bottom of the floor joists, the best option is to run the pipe parallel -- between two joists. This is a typical concern when plumbing a second-story bathroom, because you don't want a drain line visibly dropping into the room below. In most instances, it's not feasible to

Utterly standard - the subfloor goes on, then the walls go up. Doing it any other way is rather fraught with difficulties to no benefit. You've got the general idea, though it is not really critical on the cross-joist direction (as pictured) and often the parallel to the joist direction is solved by putting blocking between
To secure the loose end of a floorboard, a new batten should be screwed alongside the old joist, extending it under the unsupported board which can then be firmly screwed down on top. Boards also sometimes warp. The surface of twisted boards can be levelled by planing or by using a floor sander, once
