In December 1997 in Siirt, Erdoğan recited a poem from a work written by Ziya Gökalp, a pan-Turkish activist of the early 20th century. His recitation included verses translated as "The mosques are our barracks, the domes our helmets, the minarets our bayonets and the faithful our soldiers...." which are not in the original version of the poem. Erdoğan said the poem had been approved by the education ministry to be published in textbooks. Under article 312/2 of the Turkish penal code his recitation was regarded as an incitement to violence and religious or racial hatred. He was given a ten-month prison sentence of which he served four months, from 24 March 1999 to 27 July 1999. Due to his conviction, Erdoğan was forced to give up his mayoral position. The conviction also stipulated a political ban, which prevented him from participating in parliamentary elections.

Mac OS X was originally presented as the tenth major version of Apple's operating system for Macintosh computers; current versions of macOS retain the major version number "10". Previous Macintosh operating systems (versions of the classic Mac OS) were named using Arabic numerals, as with Mac OS 8 and Mac OS 9. The letter "X" in Mac OS X's name refers to the number 10, a Roman numeral, and Apple has stated that it should be pronounced "ten" in this context. However, it is also commonly pronounced like the letter "X".
The consumer version of Mac OS X was launched in 2001 with Mac OS X 10.0. Reviews were variable, with extensive praise for its sophisticated, glossy Aqua interface, but criticizing it for sluggish performance. With Apple's popularity at a low, the makers of several classic Mac applications such as FrameMaker and PageMaker declined to develop new versions of their software for Mac OS X. Ars Technica columnist John Siracusa, who reviewed every major OS X release up to 10.10, described the early releases in retrospect as 'dog-slow, feature-poor' and Aqua as 'unbearably slow and a huge resource hog'.
