    (IJACSA) International Journal of Advanced Computer Science and Applications, Vol. 9, No. 9, 2018 Singkat: A Keyword-Based URL Shortener and Click Tracker Package for Django Web Application Gottfried Prasetyadi, Utomo Tri Hantoro, Achmad Benny Mutiara Faculty of Computer Science and Information Technology Gunadarma University Depok, Indonesia Abstract—In recent years, Python has been gaining popularity template (MVT) architectural pattern, which enables code reuse as web scripting/programming language. In this research we and modularity of features and functions [6]. propose Singkat, an open source uniform resource locator (URL) shortener package with web user interface built using Python- Singkat is aimed to be a highly customizable URL based Django web framework. It can be deployed and customized shortener module alternative for web applications built using in any web project based on Django framework. This makes sure Django, with complete user features for a basic deployable that administrators can gain control over data in their own package, such as web user interface, shortening using pseudo environment. Users can create shortened links using base62 random and user-chosen keyword, and clicks statistics. The values to generate pseudo random keyword. To minimize name „Singkat‟ is taken from Indonesian, which means short, phishing and other abuses, only registered users can create brief, or concise. This research centered on algorithm and shortened link using their chosen keyword, and it is possible to performance of Singkat, especially its model object, harnessing preview a link before accessing it. Registered users can also Python scripting language. monitor each click and get useful information. We also ran some tests to measure Singkat’s performance and functionality.

Y a las que se divierten programando y aprendiendo hasta altas horas de la madrugada. Non gogoa, han zangoa Hecho con un esfuerzo en tiempo considerable con una buena cantidad de software libre y más ilusión en una región llamada Euskadi. PlugIn Tapestry: Desarrollo de aplicaciones y páginas web con Apache Tapestry @picodotdev 2014 - 2019 2 Prefacio Empecé El blog de pico.dev y unos años más tarde Blog Bitix con el objetivo de poder aprender y compartir el conocimiento de muchas cosas que me interesaban desde la programación y el software libre hasta análisis de los productos tecnológicos que caen en mis manos. Las del ámbito de la programación creo que usándolas pueden resolver en muchos casos los problemas típicos de las aplicaciones web y que encuentro en el día a día en mi trabajo como desarrollador. Sin embargo, por distintas circunstancias ya sean propias del cliente, la empresa o las personas es habitual que solo me sirvan meramente como satisfacción de adquirir conocimientos. Hasta el día de hoy una de ellas es el tema del que trata este libro, Apache Tapestry. Para escribir en el blog solo dependo de mí y de ninguna otra circunstancia salvo mi tiempo personal, es com- pletamente mío con lo que puedo hacer lo que quiera con él y no tengo ninguna limitación para escribir y usar cualquier herramienta, aunque en un principio solo sea para hacer un ejemplo muy sencillo, en el momento que llegue la oportunidad quizá me sirva para aplicarlo a un proyecto real.

Consequently, they must perform a capillary test at least three times per day and, besides that, a laboratory test once or twice per month. These standard methods pose difficulty for patients since they need to prick their finger in order to determine the glucose concentration, yielding discomfort and distress. In this paper, an Internet of Things (IoT)-based framework for non-invasive blood glucose monitoring is described. The system is based on Raspberry Pi Zero (RPi) energised with a power bank, using a visible laser beam and a Raspberry Pi Camera, all implemented in a glove. Data for the non-invasive monitoring is acquired by the RPi Zero taking a set of pictures of the user fingertip and computing their histograms. Generated data is processed by an artificial neural network (ANN) implemented on a Flask microservice using the Tensorflow libraries.

  • Comparative Study on Python Web Frameworks: Flask and Django
    Devndra Ghimire Comparative study on Python web frameworks: Flask and Django Metropolia University of Applied Sciences Bachelor of Engineering Media Engineering Bachelor’s Thesis 5 May 2020 Abstract Devndra Ghimire Author(s) Comparative study on Python web frameworks: Flask and Title Django. Number of Pages 37 pages + 0 appendices Date 5 May 2010 Degree Bachelor of Engineering Degree Programme Media Engineering Specialisation option Software Engineering Instructor(s) Kari Salo, Senior Lecturer The purpose of the thesis was to the study the various features, advantages, and the limita- tion of two web development frameworks for Python programming language. It aims to com- pare the usage of Django and Flask frameworks from a novice point of view. The theoretical part of the thesis presents the various types of programming languages and web technolo- gies. In the practical part, however, the study is divided into two parts, each part observing the respective web application framework. In order to perform the comparison, a social network and eCommerce like application was built for Flask and Django respectively. The comparison was started by developing the social network application first with Flask and finished with the e-commerce application using Django. Python programing language, SQLite database for the backend and HTML, JavaS- cript, and Ajax were used for the frontend technology. At the end of the project, both appli- cations were deployed to the cloud platform called Heroku. After the comparison, it was found that the most significant advantages of Flask were that it provides simplicity, flexibility, fine-grained control and quick and easy to learn. On the other hand, Django was easy to work with because of its extensive features and support for librar- ies.

In spite of decades of historical advancements on the design and use of metaheuristics, large difficulties still remain in regards to the under- standability, algorithmic design uprightness, and performance verifiability of new technical achievements. A clear example stems from the scarce replicability of works dealing with metaheuristics used for optimization, which is often infeasible due to ambiguity and lack of detail in the presentation of the methods to be repro- duced. Additionally, in many cases, there is a questionable statistical significance of their reported results. This work aims at providing the audience with a proposal of good practices which should be embraced when conducting studies about metaheuristics methods used for optimization in order to provide scientific rigor, value and transparency.
