xxxxx proposes a radical, new space for artistic exploration, with essential contributions from a diverse range of artists, theorists, and scientists. Combining intense background material, code listings, screenshots, new translation, [the] xxxxx [reader] functions as both guide and manifesto for a thought movement which is radically opposed to entropic contemporary economies. xxxxx traces a clear line across eccentric and wide ranging texts under the rubric of life coding which can well be contrasted with the death drive of cynical economy with roots in rationalism and enlightenment thought. Such philosophy, world as machine, informs its own deadly flipside embedded within language and technology. xxxxx totally unpicks this hiroshimic engraving, offering an dandyish alternative by way of deep examination of software and substance. Life coding is primarily active, subsuming deprecated psychogeography in favour of acute wonderland technology, wary of any assumed transparency. Texts such as Endonomadology, a text from celebrated biochemist and chaos theory pioneer Otto E. Roessler, who features heavily throughout this intense volume, make plain the sadistic nature and active legacy of rationalist thought. At the same time, through the science of endophysics, a physics from the inside elaborated here, a delicate theory of the world as interface is proposed. xxxxx is very much concerned with the joyful elaboration of a new real; software-led propositions which are active and constructive in eviscerating contemporary economic culture. xxxxx embeds Perl Routines to Manipulate London, by way of software artist and Mongrel Graham Harwood, a Universal Dovetailer in the Lisp language from AI researcher Bruno Marchal rewriting the universe as code, and self explanatory Pornographic Coding from plagiarist and author Stewart Home and code art guru Florian Cramer. Software is treated as magical, electromystical, contrasting with the tedious GUI desktop applications and user-led drudgery expressed within a vast ghost-authored literature which merely serves to rehearse again and again the demands of industry and economy. Key texts, which well explain the magic and sheer art of programming for the absolute beginner are published here. Software subjugation is made plain within the very title of media theorist Friedrich Kittler's essay Protected Mode, published in this volume. Media, technology and destruction are further elaborated across this work in texts such as War.pl, Media and Drugs in Pynchon's Second World War, again from Kittler, and Simon Ford's elegant take on J.G Ballard's crashed cars exhibition of 1970, A Psychopathic Hymn. Software and its expansion stand in obvious relation to language. Attacking transparency means examining the prison cell or virus of language; life coding as William Burrough's cutup. And perhaps the most substantial and thorough-going examination is put forward by daring Vienna actionist Oswald Wiener in his Notes on the Concept of the Bio-adapter which has been thankfully unearthed here. Equally, Olga Goriunova's extensive examination of a new Russian literary trend, the online male literature of udaff.com provides both a reexamination of culture and language, and an example of the diversity of xxxxx; a diversity well reflected in background texts ranging across subjects such as Leibniz' monadology, the ur-crash of supreme flaneur Thomas de Quincey and several rewritings of the forensic model of Jack the Ripper thanks to Stewart Home and Martin Howse. xxxxx liberates software from the machinic, and questions the transparency of language, proposing a new world view, a sheer electromysticism which is well explained with reference to the works of Thomas Pynchon in Friedrich Kittler's essay, translated for the first time into English, which closes xxxxx.
