Question: Holes through a PCB are typically drilled with small-diameter drill bits made of solid coated tungsten carbide. Coated tungsten carbide is recommended since many board materials are very abrasive and drilling must be high RPM and high feed to be cost effective. Drill bits must also remain sharp so as not to mar or tear the traces. Drilling with high-speed-steel is simply not feasible since the drill bits will dull quickly and thus tear the copper and ruin the boards. The drilling is performed by automated drilling machines with placement controlled by a drill tape or drill file. These computer-generated files are also called numerically controlled drill (NCD) files or "Excellon files". The drill file describes the location and size of each drilled hole.
Is there an answer to this question: What does the "NCD" in "NCD files" mean?

Answer: numerically controlled drill

Question: In May 2013, Microsoft launched a new television campaign for Windows 8 illustrating the capabilities and pricing of Windows 8 tablets in comparison to the iPad, which featured the voice of Siri remarking on the iPad's limitations in a parody of Apple's "Get a Mac" advertisements. On June 12, 2013 during game 1 of the 2013 Stanley Cup Finals, Microsoft premiered the first ad in its "Windows Everywhere" campaign, which promoted Windows 8, Windows Phone 8, and the company's suite of online services as an interconnected platform.
Is there an answer to this question: Who did Windows 8 mock in their television campaign?

Answer: the iPad

Question: The preludes, many of which are very brief (some consisting of simple statements and developments of a single theme or figure), were described by Schumann as "the beginnings of studies". Inspired by J.S. Bach's The Well-Tempered Clavier, Chopin's preludes move up the circle of fifths (rather than Bach's chromatic scale sequence) to create a prelude in each major and minor tonality. The preludes were perhaps not intended to be played as a group, and may even have been used by him and later pianists as generic preludes to others of his pieces, or even to music by other composers, as Kenneth Hamilton suggests: he has noted a recording by Ferruccio Busoni of 1922, in which the Prelude Op. 28 No. 7 is followed by the Etude Op. 10 No. 5.
Is there an answer to this question: Who suggested that Chopin's preludes were not intended to be played as a group?

Answer: Kenneth Hamilton
