You have no way of knowing if Sunnyvale will hire you, so you take the offer of the OLM job. Yes, you have every intention of it being permanent when you accept it, because you do not know what Sunnyvale will do. No problem with ethics there.
Then, if Sunnyvale does make you an offer, you tell deAnza that an offer you can't refuse came up and you have to accept it, which is the truth. This is also ethical since you had no way of knowing they were going to offer it to you when you accepted the OLM job.
It's perfectly ethical as long as you give de Anza 2 weeks notice.
The time (or lack thereof) between your hearing of the offers is not your fault. You are placing blame and guilt upon yourself for something that is out of your control. Unless you sign a contract with deAnza to work for them for a specific length of time as part of accepting the OLM position, you have nothing to fear, and they have no ammunition with which to craft a reason to give you a bad recomendation.
