  • Confessions of an Online Stalker Acknowledgements
    CONFESSIONS OF AN ONLINE STALKER ACKNOWLEDGEMENTS The following text Confessions of an Online Stalker is my critical reflection on a 3-year research project titled Future Guides: From Information to Home carried out between 2010-2014 within the Norwegian Artistic Fellowship Programme, and around the Ber- gen Academy of Art and Design. A final exhibition of my artistic research,Your Revolu- tion Begins at Home, took place at the USF Gallery and Cinemateket in Bergen, Sep- tember 4-14, 2014. Throughout my artistic research project, I have been blessed with a succession of engaging discussion partners who have provided invaluable assistance in the development of my research. The generosity of their time and readiness to talk things through have helped me to develop and reflect on the artistic research methods used to carry out this work. The following texts take the form of a series of conversa- tions because the creation of the work takes place through a long process of discussion, debate, negotiation and reflection. As I refer to a statement made by Deleuze in my introduction, “Creation is all about mediators which means that you are always working in a group, within a dialogue.” Therefore, I would like to acknowledge the many inter- locutors who contributed throughout this long process. They are and in no particular order of importance: Ellen Røed, Frans Jacobi, Magnus Bärtås, Suzanna Milevska, Lina Selander, Marcos Garcia, Marta Peirano, Fré Sonneveld, Brendan Howell, Sadie Plant, Amanda Steggell, Jeremy Welsh, Pedro Gomez-Egaña, François

  • Why We Use Django Rather Than Flask in Asset Management System

Students, B.Tech, 5Assistant Professor, Dept. of Computer Science & Engineering, Global Institute of Technology, Jaipur Abstract: Python provide number of frameworks for web development and other applications by Django, Flask, Bottle, Web2py, CherryPy and many more. Frameworks are efficient and versatile to build, test and optimize software. A web framework is a collection of package or module which allows us to develop web applications or services. It provides a foundation on which software developers can built a functional program for a specific platform. The main purpose of this study about python framework is to analyze which is better framework among Django or flask for web development. The study implement a practical approach on PyCharm. The result of this study is - “Django is better than flask”. I. INTRODUCTION Asset management refers to the process of developing, operating, maintaining, and selling assets in a cost-effective manner. Most commonly used in finance, the term is used in reference to individuals or firms that manage assets on behalf of individuals or other entities. Asset Management System are used to manage all the assets of a company, we can use this software to manage assets in any field i.e.

  • Business Uses for Python & IBM I
    Business uses for Python & IBM i Mike Pavlak – IT Strategist [email protected] A little background, please What is Python, really? ￭ General purpose language ￭ Easy to get started ￭ Simple syntax ￭ Great for integrations (glue between systems) ￭ Access to C and other APIs ￭ Infrastructure first, but applications, too 4 Historically… ￭ Python was conceptualized by Guido Van Rossum in the late 1980’s ￭ Rossum published the first version of Python code (0.9.0) in February of 1991 at the CWI(Centrum Wiskunde & Informatica) in the Netherlands, Amsterdam ￭ Python is derived from the ABC programming language, which is a general purpose language that was also developed at CWI. ￭ Rossum chose the name “Python” since he was a fan of Monty Python’s Flying Circus. ￭ Python is now maintained by a core development team at the institute, although Rossum still holds a vital role in directing its progress and as leading “commitor”. 5 Python lineage ￭ Python 1 – 1994 ￭ Python 2 – 2000 (Not dead yet…) ▶2,7 – 2010 ￭ Python 3 – 2008 ▶3.5 – 2015 ▶3.6.2 – July 2017 ▶3.7 ➔ ETA July 2018 6 Why use it? Academia ￭ 1970’s ▶COBOL, Basic ￭ 1980’s ▶Pascal, Delphi ￭ 1990’s ▶Java ￭ 2000 ▶Python & Open Source 8 Carnegie Mellon ￭ School discovered that students understood OO ▶But could not build a logic loop to save their soul! ￭ Robert Harper, professor of CS writes: “Object-oriented programming is eliminated entirely from the introductory curriculum, because it is both anti-modular and anti- parallel by its very nature, and hence unsuitable for a modern
