First published in 1982, William Tang's Spectrum Machine Language for the Absolute Beginner is generally considered to be the best introduction to 8-bit machine code programming ever written. With many great game writers crediting this as the book that got them started, there still is no better way to learn the language at the heart of the ZX Spectrum.* * *As the original publisher Melbourne House wrote:If you are frustrated by the limitations of BASIC and want to write faster, more powerful, space-saving programs or subroutines, Spectrum Machine Language for the Absolute Beginner is the book for you.Even with no previous experience of computer languages, you will be able to discover the ease and power of the Spectrum's own language. Each chapter includes specific examples of machine language applications which can be demonstrated and used on your Spectrum as well as a self-test questionnaire.At the end of the book, all this is brought together in an entire machine langua.

L’analyse élémentaire a connu des développements instrumentaux majeurs depuis les années 70. C’est tout particulièrement le cas avec la spectrométrie d’émission atomique à source plasma (ICP-OES), commercialisée pour la première fois en 1974, et qui s’est rapidement imposée en se déployant très largement dans les laboratoires de caractérisation. Bien que l’ICP-OES soit devenue une technique d’analyse de routine, les exigences de la mesure imposent une maîtrise complète du processus opératoire et du système de management de la qualité associé. L’objectif de cet ouvrage est de guider l’analyste durant tout le processus de validation de sa mesure et de l’aider à garantir la maîtrise de ses principales étapes : gestion administrative et physique des échantillons au laboratoire ; préparation et traitement de ceux-ci avant mesure ; qualification et suivi de l’appareillage ; réglages instrumentaux et stratégie d’étalonnage ; exploitation des résultats en termes de justesse, fidélité, incertitude et exactitude (avec la détermination pratique du « profil d’exactitude »). Le guide s’appuie pour cela sur la terminologie la plus actuelle et sur de nombreux exemples et illustrations destinés à faciliter la compréhension et la constitution des dossiers de validation de méthode. Cet ouvrage collectif a été constitué dans le cadre des travaux de la Commission d’ÉTAblissement des Méthodes d’Analyses du Commissariat à l’Énergie Atomique et aux Énergies Alternatives. Trente-huit spécialistes de l’ICP-OES, travaillant dans des laboratoires de recherches de grands organismes (AREVA, ARKEMA, CEA, C2RMF, EDF, EURODIF, IRSN) et d’Universités (Université de Pau et des Pays de l’Adour, Université Claude Bernard Lyon 1), y ont contribué durant plus de dix ans.

This monograph was written from the perspective of the demoscene, i.e. users and creators whose interests are focused on the capabilities of the British 8-bit computer ZX Spectrum. The book does not include the official history of the computer, but the local narrative. The authors examine the processes of "taking over" the western platform, e.g. mass cloning of the hardware. They investigate creative artifacts specific to the ZX Spectrum scene and discuss the computer's capabilities for creating graphics, music, demos and games, applying the ethnographic method as well as platform studies and media archeology.
