Passage: At present the A35 autoroute, which parallels the Rhine between Karlsruhe and Basel, and the A4 autoroute, which links Paris with Strasbourg, penetrate close to the centre of the city. The Grand contournement ouest (GCO) project, programmed since 1999, plans to construct a 24 km (15 mi) long highway connection between the junctions of the A4 and the A35 autoroutes in the north and of the A35 and A352 autoroutes in the south. This routes well to the west of the city and is meant to divest a significant portion of motorized traffic from the unité urbaine.

The key feature of this application is that it can organize photos into groups according to various criteria. Notable categorizations are colors, ages, or facial expressions of the people in the photos. Slideshows can be viewed with the application, along with music and playlists. The software was updated with the release of system software version 3.40 allowing users to upload and browse photos on Facebook and Picasa.

question:
Passage: Serious American students of theology and divinity, particularly in New England, regarded Hebrew as a classical language, along with Greek and Latin, and essential for study of the Old Testament in the original words. The Reverend Ezra Stiles, president of the College from 1778 to 1795, brought with him his interest in the Hebrew language as a vehicle for studying ancient Biblical texts in their original language (as was common in other schools), requiring all freshmen to study Hebrew (in contrast to Harvard, where only upperclassmen were required to study the language) and is responsible for the Hebrew phrase אורים ותמים (Urim and Thummim) on the Yale seal. Stiles' greatest challenge occurred in July 1779 when hostile British forces occupied New Haven and threatened to raze the College. However, Yale graduate Edmund Fanning, Secretary to the British General in command of the occupation, interceded and the College was saved. Fanning later was granted an honorary degree LL.D., at 1803, for his efforts.
answer:

When was Ezra Stiles vice president of Yale?
