What's Wring With This Picture: Bored Holes in Floor Joists?

Only 2 of the spans appear to be in the center assuming the El on the left is the end of the piping. The rest are near a wall. Looks plenty strong to me though I'd like to see some wood/construction adhesive in the sistering also.

Bored holes and notches are not the same thing.

Only notches are restricted to the end thirds or rafters or joists.

Holes can be bored anywhere along the length in a sawn lumber joist or rafter according to building codes.

The exception is for truss joists which can be bored only in locations specified by the manufacturer.
