By the time you are holding this book in your hands, I will have 30 years in since the first time I wrote some code. That code was ROM-BASIC on a TRS-80 in Washington grammar school in Owosso, Michigan, and I was in the fifth grade. Making the “tank” slide back and forth shooting blips across the screen was neat. Changing the code to change blip speeds and numbers of targets was exhilaratin…
To know and cooperate with the laws of health in order to retain, or regain, health is most important. The study of disease takes a secondary place to the study of the laws of life. To know how to employ every rational means at our disposal in order to avert sickness should be our constant study and goal. Life’s activities are centered in the home. Parents should be an example of good h…
One important premise of Hicks’s theoretical framework is the distinction between the structure of reality and the purpose-oriented arrangement of human actions. There are reasons to believe that, at an early stage of his development as an economist, Hicks came across the distinction between an ‘order of being’ and an ‘order of doing,’ as discussed by Maffeo Pantaleoni (Pantaleoni, 19…
Text editing is one of the most common tasks on any computer system, and vi is one of the most useful standard text editors on a system. With vi you can create new files or edit any existing text-only file. vi, like many of the classic utilities developed during the early years of Unix, has a reputation for being hard to navigate. Bram Moolenaar’s enhanced clone, Vim (“vi Improved”), has …
Learning Redis is meant to be a guide and handbook for developers, architects, solution providers, consultants, engineers, and anyone planning to learn, design, and architect an Enterprise Solution and looking for an in-memory datastore that is agile and fast and extends its capabilities beyond just storing data. This book starts with an introduction to the evolving landscape of NoSQL, explor…
We frequently talk about “changing society,”2 but society has always been changing. Today, “change” seems to have become an intrusive concept, possibly because change occurs at a much faster pace than before, and the consequences are much more extensive.3 Even small changes have greater consequences than we were previously aware of. “Chaos theory” predicts that a butterfly flapping …
A Fluid-Structure Interaction model is studied for aortic flow, based on Koiter’s shell model for the structure, Navier–Stokes equations for the fluid and transpiration for the coupling. It accounts for wall deformation while yet working on a fixed geometry. The model is established first. Then a numerical approximation is proposed and some tests are given. The model is also used for optima…
