  • Raritas: a Program for Counting High Diversity Categorical Data with Highly Unequal Abundances
    Raritas: a program for counting high diversity categorical data with highly unequal abundances David B. Lazarus1, Johan Renaudie1, Dorina Lenz2, Patrick Diver3 and Jens Klump4 1 Museum für Naturkunde, Berlin, Germany 2 Leibniz-Institut für Zoo- und Wildtierforschung, Berlin, Germany 3 Divdat Consulting, Wesley, AR, USA 4 CSIRO, Mineral Resources, Kensington, NSW, Australia ABSTRACT Acquiring data on the occurrences of many types of difficult to identify objects are often still made by human observation, for example, in biodiversity and paleontologic research. Existing computer counting programs used to record such data have various limitations, including inflexibility and cost. We describe a new open-source program for this purpose—Raritas. Raritas is written in Python and can be run as a standalone app for recent versions of either MacOS or Windows, or from the command line as easily customized source code. The program explicitly supports a rare category count mode which makes it easier to collect quantitative data on rare categories, for example, rare species which are important in biodiversity surveys. Lastly, we describe the file format used by Raritas and propose it as a standard for storing geologic biodiversity data. ‘Stratigraphic occurrence data’ file format combines extensive sample metadata and a flexible structure for recording occurrence data of species or other categories in a series of samples.

  • Application Programming Interface (API) Is a Specification Intended to Be Used As an Interface by Software Components to Communicate with Each Other
    Application programming interface 1 Application programming interface An application programming interface (API) is a specification intended to be used as an interface by software components to communicate with each other. An API may include specifications for routines, data structures, object classes, and variables. An API specification can take many forms, including an International Standard such as POSIX or vendor documentation such as the Microsoft Windows API, or the libraries of a programming language, e.g. Standard Template Library in C++ or Java API. An API differs from an application binary interface (ABI) in that the former is source code based while the latter is a binary interface. For instance POSIX is an API, while the Linux Standard Base is an ABI.[1] Language used An API can be: • language-dependent, meaning it is only available by using the syntax and elements of a particular language, which makes the API more convenient to use. • language-independent, written so that it can be called from several programming languages. This is a desirable feature for a service-oriented API that is not bound to a specific process or system and may be provided as remote procedure calls or web services. For example, a website that allows users to review local restaurants is able to layer their reviews over maps taken from Google Maps, because Google Maps has an API that facilitates this functionality. Google Maps' API controls what information a third-party site can use and how they can use it. The term API may be used to refer to a complete interface, a single function, or even a set of APIs provided by an organization.

  • Comparative Studies of Six Programming Languages
    Comparative Studies of Six Programming Languages Zakaria Alomari Oualid El Halimi Kaushik Sivaprasad Chitrang Pandit Concordia University Concordia University Concordia University Concordia University Montreal, Canada Montreal, Canada Montreal, Canada Montreal, Canada [email protected] [email protected] [email protected] [email protected] Abstract Comparison of programming languages is a common topic of discussion among software engineers. Multiple programming languages are designed, specified, and implemented every year in order to keep up with the changing programming paradigms, hardware evolution, etc. In this paper we present a comparative study between six programming languages: C++, PHP, C#, Java, Python, VB ; These languages are compared under the characteristics of reusability, reliability, portability, availability of compilers and tools, readability, efficiency, familiarity and expressiveness. 1. Introduction: Programming languages are fascinating and interesting field of study. Computer scientists tend to create new programming language. Thousand different languages have been created in the last few years. Some languages enjoy wide popularity and others introduce new features. Each language has its advantages and drawbacks. The present work provides a comparison of various properties, paradigms, and features used by a couple of popular programming languages: C++, PHP, C#, Java, Python, VB. With these variety of languages and their widespread use, software designer and programmers should to be aware

  • Google App Engine Download Windows Google App Engine
    google app engine download windows Google App Engine. Create your own web applications using Google's infrastructure. Latest version. More and more programmers are giving the jump onto the web and programming applications that can be accessed through a browser. Google App Engine is the Google solution for programming and publishing online web applications quickly, and easily. You can use several programming languages, among which the most important are Python and Java. The documentation includes examples and tutorials so you can create an application in minutes. Google's infrastructure allows you to forget about your application's technical requirements. If you need more power, you can buy it and have it available almost instantly. Installation of Google App Engine includes an application with which you can manage the applications and load them onto your Google account. How do you host your website on Google App Engine? Google App Engine is a powerful platform that lets you build and run applications on Google’s infrastructure — whether you need to build a multi- tiered web application from scratch or host a static website. Here's a step-by-step guide to hosting your website on Google App Engine. Creating a Google Cloud Platform project. To use Google's tools for your own site or app, you need to create a new project on Google Cloud Platform. This requires having a Google account. Go to the App Engine dashboard on the Google Cloud Platform Console and press the Create button. If you've not created a project before, you'll need to select whether you want to receive email updates or not, agree to the Terms of Service, and then you should be able to continue.
