In almost every public place today the ears are assailed by the sound of pop music. In shopping malls, public houses, restaurants, hotels and elevators the ambient sound is not human conversation but the music disgorged into the air by speakers – usually invisible and inaccessible speakers that cannot be punished for their impertinence. For the most part, the prevailing music is of an astounding banality – it is there in order not to be really there. It is a background to the business of consuming things, a surrounding nothingness on which we scribble the graffiti of our desires. Whole areas of civic space in our society are now policed by this sound, which drives anybody with the slightest feeling for music to distraction, and ensures that for many of us a visit to the pub or a meal in a restaurant have lost their residual meaning. These are no longer social events, but experiments in endurance, as you shout at each other over the deadly noise. There are two reasons why this vacuous music has flown into every public space. One is the vast change in the human ear brought about by the mass production of sound. The other is the failure of the law to protect us from the result. For our ancestors music was something that you sat down to listen to, or which you made for yourself. It was a ceremonial event, in which you participated, either as a passive listener or as an active performer. With the advent of the gramophone, the radio and now the iPod, music is no longer something that you must make for yourself, nor is it something that you sit down to listen to. It follows you about wherever you go, and you switch it on as a background. It is not so much listened to as overheard. The banal melodies and mechanical rhythms, the stock harmonies recycled in song after song, these things signify the eclipse of the musical ear. For many people music is no longer a language shaped by our deepest feelings, no longer a place of refuge from the tawdriness and distraction of everyday life, no longer an art in which gripping ideas are followed to their distant conclusions. It is simply a carpet of sound, designed to bring all thought and feeling down to its own level lest something serious might be felt or said. And there is no law against it. You are rightly prevented from polluting the air of a restaurant with smoke; but nothing prevents the owner from inflicting this far worse pollution on his customers – pollution that poisons not the body but the soul. Background music is the default position. It is no longer silence to which we return when we cease to speak, but the empty chatter of the music-box. Silence must be excluded at all cost, since it awakens you to the emptiness that looms on the edge of modern life, threatening to confront you with the dreadful truth, that you have nothing whatever to say.

The building blocks required to achieve success in a business domain and differentiate the company from its competitors: Core domains : The interesting problems. These are the in-house activities the company is performing differently from its competitors and from which it gains its competitive advantage. Generic domains : The solved problems. These are the things all companies are doing in the same way. There is no room or need for innovation here; rather than creating in-house implementations, it’s more cost-effective to adopt \ buy existing solutions. Supporting domains: The problems with obvious solutions. These are the activities the company likely has to implement in-house or outsourced, but that do not provide any competitive advantage. Domain experts are subject matter experts who know all the intricacies of the business that we are going to model and implement in code. In other words, domain experts are knowledge authorities in the software’s business domain. T
