His mainproject was the small area unemployment statistics System which has been in officialuse at the hungarian Public employment service since then he learned about the pythonprogramming language here in 2000. he set up his own consulting company in 2002 andthen he worked on various projects for insurance, pharmacy and e-commerce companiesusing Python whenever he could he also worked in a European Union research institutein Italy testing and enhanching a distributed, Python- based Zope/Plone web applicationHe moved to Great Britain in 2007 and first he worked at a Scottish start-up, using twistedPython then in the aerospace industry in england using among others the py at windowingtoolkit, the Enthought application framework, and the Num Py and SciPy libraries. Hereturned to Hungary in 2012 and he rejoined multiracio where now he is working on aPython extension module to OpenOffice /Eurooffice, using NumPy and sciPy again, which willallow users to solve non-linear and stochastic optimization problems miklos likes to travelread, and he is interested in sciences, linguistics, history politics, the board game of go, andin quite a few other topics. besides he always enjoys a good cup of coffee. However, nothingbeats spending time with his brilliant 10 year old son Zsombor for himNikolay kare lin holds a phd degree in optics and used various methods of numericalsimulations and analysis for nearly 20 years first in academia and then in the industrysimulation of fiber optics communication links). After initial learning curve with Pythonand Num Py, these excellent tools became his main choice for almost all numerical analysisand scripting, since past five yearsI wish to thank my family for understanding and keeping patience duringlong evenings when I was working on reviews for the "NumPy BeginnersGuide,www.packtpuB.comSupport files, eBooks, discount offers and moreYoumightwanttovisitwww.Packtpub.comforsupportfilesanddownloadsrelatedtoyour bookDid you know that Packt offers e boak versions of every book published, with PDF and epub filesavailableYoucanupgradetotheebookversionatwww.Packtpub.comandasaprintbookcustomer, you are entitled to a discount on the e book copy. get in touch with us at serviceapacktpub. com for more detailsAtwww.Packtpub.comyoucanalsoreadacollectionoffreetechnicalarticlessignupforarange of free newsletters and receive exclusive discounts and offers on packt books and e booksPACKTLIB°http://packtlib.Packtpub.comDo you need instant solutions to your it questions?
