Context paragraphs:
Schilling of Solothurn: The family of the two Swiss chroniclers called Diebold Schilling was originally from Solothurn.  Klewi Schilling was a somewhat dubious character, and he was banned from the city, settling in Hagenau (Alsace), and probably died in Kaysersberg.

Diebold Schilling the Younger: Diebold Schilling the Younger (before 1460 - 3 November 1515(?))  was the author of the "Luzerner Schilling", one of the Swiss illustrated chronicles, which he presented to the city council of Lucerne on 15 January 1513 (but which remained incomplete).  He was the nephew of Diebold Schilling the Elder of Berne.  The younger Diebold was a somewhat scandalous figure, not unlike his father Hans, brother to the elder Diebold, an adventurer who had sought his fortune at the court of Matthias Corvinus, and returned destitute in 1488.  Diebold was a secretary in Lucerne from 1479, and received the priesthood in 1481.  His behaviour was so unpriestly, however, that the city council locked him into the tower in 1487, where he remained imprisoned for two years before he was released on parole of exhibiting more appropriate behaviour in the future.  After his release he was soon back to his old ways, and after he had killed a man after a tavern brawl, he was fined and obliged to read a mass for his victim every year.  Diebold was fiercely anti-French, and he accused the Bernese in particular, as well as his fellow chronicler Petermann Etterlin because of their friendly attitude towards France.  Diebold's own sympathies lay with the German emperor Maximilian I, who personally invited him to the Reichstag in Konstanz in 1507.  As an author, Diebold's most important contribution to the historiography of his times is his account of the years 1507–1509, the events of which he tells in his own words as an eye-witness.

Diebold Schilling the Elder: Diebold Schilling the Elder (c. 1445–1485) was the author of several of the Swiss illustrated chronicles, the "Berner Schilling of 1483, the "Spiezer Schilling" (1480s), and the "Zürcher Schilling" of 1484.

Hacking Democracy: Hacking Democracy is the 2006 Emmy nominated documentary film broadcast on HBO and created by producer / directors Russell Michaels and Simon Ardizzone and producer Robert Carrillo Cohen and executive producers Sarah Teale & Sian Edwards.  Filmed over three years it documents American citizens investigating anomalies and irregularities with 'e-voting' (electronic voting) systems that occurred during the 2000 and 2004 elections in the U.S.A., especially in Volusia County, Florida.  The film investigates the flawed integrity of electronic voting machines, particularly those made by Diebold Election Systems, exposing previously unknown backdoors in the Diebold trade secret computer software.  The film culminates dramatically in the on-camera hacking of the in-use / working Diebold election system in Leon County, Florida - the same computer voting system which has been used in actual American elections across thirty-three states, and which still counts tens of millions of America's votes today.
