17、 the AuthorWolfgang Mauerer is a quantum physicist whose professional interests are centered around quantumcryptography, quantum electrodynamics, and compilers for you guessed it quantum architectures.With the confirmed capacity of being the worst experimentalist in the known universe, he sticks to
18、thetheoretical side of his profession, which is especially reassuring considering his constant fear of acci-dentally destroying the universe. Outside his research work, he is fascinated by operating systems, andfor more than a decade starting with an article series about the kernel in 1997 he has fo
19、und greatpleasure in documenting and explaining Linux kernel internals. He is also the author of a book abouttypesetting with LaTeX and has written numerous articles that have been translated into seven languagesin total.When hes not submerged in vast Hilbert spaces or large quantities of source cod
20、e, he tries to take theopposite direction, namely, upward be this with model planes, a paraglider, or on foot with an ice axein his hands: Mountains especially have the power to outrival even the Linux kernel. Consequently, heconsiders planning and accomplishing a first-ascent expedition to the vast
21、 arctic glaciers of east Green-land to be the really unique achievement in his life.Being interested in everything that is fundamental, he is also the author of the first compiler forPlankalk ul, the worlds earliest high-level language devised in 19421946 by Konrad Zuse, the father ofthe computer. A
22、s an avid reader, he is proud that despite the two-digit number of computers present inhis living room, the volume required for books still occupies a larger share.Mauerer fauth.tex V2 - 08/22/2008 4:52am Page viMauerer fcredit.tex V2 - 08/22/2008 4:53am Page viiCreditsExecutive EditorCarol LongSeni
