This may have been answered by pianolover's links. I admit I did not click on them, but assumed they were examples of each.
To an untrained ear, this might be considered a study in semantics. I think I would prefer to call it evolution. Ragtime came first, stride came second. Ragtime around the turn of the 20th century, stride during the roaring twenties. There is a striking similarity, because stride is frequently (though not always) considered the successor to ragtime. The "stride" bass is featured in both quite extensively.
I typically dissociate the "stride" bass from the musical style of "stride", and then can apply the bass pattern "name" to either form. This can cause some confusion if you don't know the difference in form, but it makes it an easier descriptor for the bass pattern.
This style of playing is one of my strengths. Octaves, large leaps and chords fit very well under my hands because my first teacher was a blues/jazz pianist. So, I learned all about "strutting" the left hand.
