XUL stands for XML User Interface Language. It is an XML markup language that allows for GUI-based application creation using the Gecko and Goanna layout engines. In turn, these layout engines provide several technologies used to build applications. Pale Moon and Waterfox are just two applications built using XUL and the Gecko/Goanna layout engine. XUL makes it easy to build your own stand-alone applications through the use of XPCOM, JavaScript, HTML and CSS. This book is intended to be a quick start-style resource to give you the basics of creating a XUL GUI along with how to make that GUI actually do something using JavaScript and XPCOM. This 7th Edition incorporates information on using Waterfox and Pale Moon as the basis for your own stand-alone applications. Expanded information on notification boxes, popups and panels is also included in his new edition.

In the twentieth century, avant-garde artists from Mexico, Central and South America, and the Caribbean created extraordinary and highly innovative paintings, sculptures, assemblages, mixed-media works, and installations. This innovative book presents more than 250 works by some seventy of these artists (including Gego, Joaquin Torres-Garcia, Xul Solar, and Jose Clemente Orozco) and artists' groups, along with interpretive essays by leading authorities and newly translated manifestoes and other theoretical documents written by the artists. Together the images and texts showcase the astonishing artistic achievements of the Latin American avant-garde. The book focuses on two decisive periods: the return from Europe in the 1920s of Latin American avant-garde pioneers; and the expansion of avant-garde activities throughout Latin America after World War II as artists expressed their independence from developments in Europe and the United States. As the authors explain, during these periods Latin American art was fueled by the belief that artistic creations could present a form of utopia - an inversion of the original premise that drove the European avant-garde - and serve as a model for

Tropical geometry is a combinatorial shadow of algebraic geometry, offering new polyhedral tools to compute invariants of algebraic varieties. It is based on tropical algebra, where the sum of two numbers is their minimum and the product is their sum. This turns polynomials into piecewise-linear functions, and their zero sets into polyhedral complexes. These tropical varieties retain a surprising amount of information about their classical counterparts. Tropical geometry is a young subject that has undergone a rapid development since the beginning of the 21st century. While establishing itself as an area in its own right, deep connections have been made to many branches of pure and applied mathematics. This book offers a self-contained introduction to tropical geometry, suitable as a course text for beginning graduate students. Proofs are provided for the main results, such as the Fundamental Theorem and the Structure Theorem. Numerous examples and explicit computations illustrate the main concepts. Each of the six chapters concludes with problems that will help the readers to practice their tropical skills, and to gain access to the research literature. This wonderful book will appeal to students and researchers of all stripes: it begins at an undergraduate level and ends with deep connections to toric varieties, compactifications, and degenerations. In between, the authors provide the first complete proofs in book form of many fundamental results in the subject. The pages are sprinkled with illuminating examples, applications, and exercises, and the writing is lucid and meticulous throughout. It is that rare kind of book which will be used equally as an introductory text by students and as a reference for experts. —Matt Baker, Georgia Institute of Technology Tropical geometry is an exciting new field, which requires tools from various parts of mathematics and has connections with many areas. A short definition is given by Maclagan and Sturmfels: “Tropical geometry is a marriage between algebraic and polyhedral geometry”. This wonderful book is a pleasant and rewarding journey through different landscapes, inviting the readers from a day at a beach to the hills of modern algebraic geometry. The authors present building blocks, examples and exercises as well as recent results in tropical geometry, with ingredients from algebra, combinatorics, symbolic computation, polyhedral geometry and algebraic geometry. The volume will appeal both to beginning graduate students willing to enter the field and to researchers, including experts. —Alicia Dickenstein, University of Buenos Aires, Argentina
