The intent of this Success Criterion is to provide enough contrast between text and its background so that it can be read by people with moderately low vision (who do not use contrast-enhancing assistive technology). For people without color deficiencies, hue and saturation have minimal or no effect on legibility as assessed by reading performance (Knoblauch et al., 1991). Color deficiencies can affect luminance contrast somewhat. Therefore, in the recommendation, the contrast is calculated in such a way that color is not a key factor so that people who have a color vision deficit will also have adequate contrast between the text and the background.
Joe from Reverb.com explains the theoretical structure of a diminished chord, a couple of shapes to play them on guitar, and their common uses.
Sweetwater have two informative guides to microphones which, although part of a sales pitch, cover the broad categories and applications of microphones.
The live microphone guide is also useful.
Joe Gore for Premier Guitar:
Consider how most of us practice: with loud amps aimed at our butts. Yeah, it’s fun, but it can cultivate a warped sense of how parts should sound in context. Over time, that butt-thumping sensation becomes synonymous with “good tone.” Hearing ourselves from any other source—studio monitors, say, or the crappy little computer speakers and ear buds used by most of today’s music consumers—feels wimpy in comparison. That can make us play too loudly, mix ourselves too prominently, and monitor ourselves so deafeningly while recording that we can’t hear ourselves within the production.
Hossein Derakhshan, a blogger who was jailed in 2008, writes about changes in the web.
Six years was a long time to be in jail, but it’s an entire era online. Writing on the internet itself had not changed, but reading — or, at least, getting things read — had altered dramatically. I’d been told how essential social networks had become while I’d been gone, and so I knew one thing: If I wanted to lure people to see my writing, I had to use social media now.
Even before I went to jail, though, the power of hyperlinks was being curbed. Its biggest enemy was a philosophy that combined two of the most dominant, and most overrated, values of our times: novelty and popularity, reflected by the real world dominance of young celebrities. That philosophy is the Stream.
