This input embedding is the initial value of the residual stream, which all attention layers and MLPs read from and write to.

A falsey return value from #validate will deviate the flow and go straight to End.fail_fast.

Important caveat: in the combined expression, if the middle command has a non-zero exit status, then both the middle and the rightmost command end up getting executed.

bedmap && mv || fail

⟫ true && false || echo 'fail'
fail

⟫ false && true || echo 'fail'
fail

The potential problem: if second_task fails, third_task will not run, and execution will continue to the next line of code - next_task, in this example. This may be exactly the behavior you want. Alternatively, you may be intending that if second_task fails, the script should immediately exit with its error code. In this case, the best choice is to use a block - i.e., curly braces: first_task && { second_task third_task } next_task Because we are using the -e option, if second_task fails, the script immediately exits.

When people write COND && COMMAND, typically they mean "if COND succeeds (or is boolean true), then execute COMMAND. Regardless, proceed to the next line of the script." It's a very convenient shorthand for a full "if/then/fi" clause.

For instance, cor does not distribute over cand: compare (A cand B) cor C with (A cor C) cand (B cor C); in the case ¬A ∧ C , the second expression requires B to be defined, the first one does not

this system enables longer duration production, and could be readily applied to burdensome or toxic products not readily produced in bacteria
