Universidad Complutense de Madrid Sistema de gestión de información de usuarios y resultados para el paquete 2008/09 informático GeneCodis Página 2 Sistema de gestión de información de usuarios y resultados para el paquete 2008/09 informático GeneCodis Resumen GeneCodis cuenta en la actualidad con una media de 500 trabajos reales provenientes de distintas partes del mundo, en especial de Europa, USA y Japón. Así mismo, el número de procesos realizados por el mismo usuario es también alto y la tendencia es aumentar. Este número elevado de procesos por usuario hace que la gestión de la información sea imprecisa poco fiable y prácticamente imposible de gestionar de una manera organizada ya que la manera de notificación existente en la actualidad está basada en el correo electrónico o en el almacenamiento manual de las URL con los resultados, por lo tanto, este proyecto pretende minimizar estos problemas mediante la realización de una gestión de los trabajos. Palabras Claves • GeneCodis • Ruby • Rails • Camping • Bioinformática • Análisis funcional • Bases de datos • HTML Página 3 Sistema de gestión de información de usuarios y resultados para el paquete 2008/09 informático GeneCodis Abstract Nowadays, Genecodis has about 500 real works which come from different places of the world, especially from Europe, USA and Japan. Moreover, the number of process which is realized by the same user is usually large and it normally goes on increasing. -

An Experimental Study of the Performance, Energy, and Programming Effort Trade-Offs of Android Persistence Frameworks
An Experimental Study of the Performance, Energy, and Programming Effort Trade-offs of Android Persistence Frameworks Jing Pu Thesis submitted to the Faculty of the Virginia Polytechnic Institute and State University in partial fulfillment of the requirements for the degree of Master of Science in Computer Science and Applications Eli Tilevich, Chair Barbara G. Ryder Francisco Servant July 1, 2016 Blacksburg, Virginia Keywords: Energy Efficiency; Performance; Programming Effort; Orthogonal Persistence; Android; Copyright 2016, Jing Pu An Experimental Study of the Performance, Energy, and Programming Effort Trade-offs of Android Persistence Frameworks Jing Pu (ABSTRACT) One of the fundamental building blocks of a mobile application is the ability to persist program data between different invocations. Referred to as persistence, this functionality is commonly implemented by means of persistence frameworks. When choosing a particular framework, Android|the most popular mobile platform—offers a wide variety of options to developers. Unfortunately, the energy, performance, and programming effort trade-offs of these frameworks are poorly understood, leaving the Android developer in the dark trying to select the most appropriate option for their applications. To address this problem, this thesis reports on the results of the first systematic study of six Android persistence frameworks (i.e., ActiveAndroid, greenDAO, Orm- Lite, Sugar ORM, Android SQLite, and Realm Java) in their application to and performance with popular benchmarks, such as DaCapo. Having measured and ana- lyzed the energy, performance, and programming effort trade-offs for each framework, we present a set of practical guidelines for the developer to choose between Android persistence frameworks. Our findings can also help the framework developers to optimize their products to meet the desired design objectives. -
Load Testing of Containerised Web Services
UPTEC IT 16003 Examensarbete 30 hp Mars 2016 Load Testing of Containerised Web Services Christoffer Hamberg Abstract Load Testing of Containerised Web Services Christoffer Hamberg Teknisk- naturvetenskaplig fakultet UTH-enheten Load testing web services requires a great deal of environment configuration and setup. Besöksadress: This is especially apparent in an environment Ångströmlaboratoriet Lägerhyddsvägen 1 where virtualisation by containerisation is Hus 4, Plan 0 used with many moving and volatile parts. However, containerisation tools like Docker Postadress: offer several properties, such as; application Box 536 751 21 Uppsala image creation and distribution, network interconnectivity and application isolation that Telefon: could be used to support the load testing 018 – 471 30 03 process. Telefax: 018 – 471 30 00 In this thesis, a tool named Bencher, which goal is to aid the process of load testing Hemsida: containerised (with Docker) HTTP services, is http://www.teknat.uu.se/student designed and implemented. To reach its goal Bencher automates some of the tedious steps of load testing, including connecting and scaling containers, collecting system metrics and load testing results to name a few. Bencher’s usability is verified by testing a number of hypotheses formed around different architecture characteristics of web servers in the programming language Ruby. With a minimal environment setup cost and a rapid test iteration process, Bencher proved its usability by being successfully used to verify the hypotheses in this thesis. However, there is still need for future work and improvements, including for example functionality for measuring network bandwidth and latency, that could be added to enhance process even further. To conclude, Bencher fulfilled its goal and scope that were set for it in this thesis. -
An Introduction to Ruby and Rails
An Introduction to Ruby and Rails This paper was originally presented at the Southwest Fox conference in Gilbert, Arizona in October, 2010. http://www.swfox.net An Introduction to Ruby and Rails Rick Borup Information Technology Associates 701 Devonshire Dr, Suite 127 Champaign, IL 61820 Voice: (217) 359-0918 Fax: (217) 398-0413 Email: [email protected] Ruby is a powerful, object-oriented, open-source language with a clean and easily understandable syntax. Originally released to the public in 1995, wide-spread interest in the Ruby language really began to take off in 2003 with the release of the Ruby on Rails® framework. Also known as "RoR" or simply "Rails", Ruby on Rails is an open-source Web framework that makes it possible to quickly and easily create data-based Web applications. Together, the Ruby language and the Ruby on Rails framework can become an exciting and powerful addition to any developer's toolbox. This session introduces both the Ruby language and the Rails framework, focusing on their installation and use on a Windows® platform with a perspective geared toward experienced Visual FoxPro® developers. © 2010 Rick Borup Page 1 of 64 An Introduction to Ruby and Rails Table of Contents Introduction............................................................................................................................................................ 4 Installing Ruby and Rails on Windows......................................................................................................... 4 Installing Instant Rails -
