Gerold (died 799) was an Alamannian nobleman who served the Frankish King, Charlemagne, as Margrave of the Avarian March and Prefect of Bavaria in what is now South-Eastern Germany.
 Gerold played a significant role in the integration of Bavaria into the Frankish Kingdom during Carolingian expansion in the late 8th, and early 9th centuries.
 Gerold both aided the continuity of Agilofing rule of Bavaria, as well as took steps to integrate Bavarians into the wider scope of the Frankish Kingdom.
 Gerold was related both to the Agilofing family, the ruling class of Bavaria, as well as the Carolingian family.
 The Agilofings had ruled Bavaria since Duke Garibald I in 548.
 Gerold was born into the Agilofings, and his sister Hildegard was married to Charlemagne in 771.
From these familial connections, he was appointed Prefect of Bavaria following the deposition of Duke Tassilo III in 788.
 Gerold was heralded as a superb military commander, giving rise to his promotion to Prefect as a defender of the eastern border of the Frankish Kingdom.
 In 799, Gerold is said to have fallen in battle against the Avars, shortly after the same Avars killed his ally, Erich, Duke of Friuli, through treachery.
Ag-gag is a term used to describe a class of anti-whistleblower laws that apply within the agriculture industry.
 Coined by Mark Bittman in an April 2011 "New York Times" column, the term "ag-gag" typically refers to state laws that forbid the act of undercover filming or photography of activity on farms without the consent of their owner—particularly targeting whistleblowers of animal rights abuses at these facilities.
 These laws originated in the United States, but have also begun to appear elsewhere, such as in Australia.
 Some of these laws, such as the failed proposal in Pennsylvania, have a wider scope and could be used to criminalize actions by activists in other industries.
ALGOL 68 (short for ALGOrithmic Language 1968) is an imperative computer programming language that was conceived as a successor to the ALGOL 60 programming language, designed with the goal of a much wider scope of application and more rigorously defined syntax and semantics.
