In 1988, Apple sued Microsoft and Hewlett-Packard on the grounds that they infringed Apple's copyrighted GUI, citing (among other things) the use of rectangular, overlapping, and resizable windows. After four years, the case was decided against Apple, as were later appeals. Apple's actions were criticized by some in the software community, including the Free Software Foundation (FSF), who felt Apple was trying to monopolize on GUIs in general, and boycotted GNU software for the Macintosh platform for seven years.
What are some of the issues Apple cited in the lawsuit against Microsoft and HP?
the use of rectangular, overlapping, and resizable windows

A tile mosaic is a digital image made up of individual tiles, arranged in a non-overlapping fashion, e.g. to make a static image on a shower room or bathing pool floor, by breaking the image down into square pixels formed from ceramic tiles (a typical size is 1 in × 1 in (25 mm × 25 mm), as for example, on the floor of the University of Toronto pool, though sometimes larger tiles such as 2 in × 2 in (51 mm × 51 mm) are used). These digital images are coarse in resolution and often simply express text, such as the depth of the pool in various places, but some such digital images are used to show a sunset or other beach theme.
What is the typical size of a ceramic mosaic tile?
1 in × 1 in

The vicereine Germaine of Foix brutally repressed the uprising and its leaders, and this accelerated the authoritarian centralisation of the government of Charles I. Queen Germaine favoured harsh treatment of the agermanats. She is thought to have signed the death warrants of 100 former rebels personally, and sources indicate that as many as 800 executions may have occurred. The agermanats are comparable to the comuneros of neighbouring Castile, who fought a similar revolt against Charles from 1520–1522.
What group in Castile was similar to the agermanats?
comuneros
