Most current multi-touch libraries provide support to recognize the touch input from particular hardware and seldom support complex gestures. For rapid prototyping and development of multi-touch applications, particularly for collaboration across multiple disparate devices, there is a need for a framework which can support an array of multi-touch hardware, provide gesture processing, be cross platform compatible, and allow applications to be developed in the desired programming language. In this paper we present criteria for evaluating a multi-touch library and “Sparsh UI”— an open source multi-touch library which is a novel attempt to address these issues by enabling developers to easily develop multi-touch applications. We also compare Sparsh UI with other multi-touch libraries and describe several Sparsh-based applications, including BasePlate, a system for collaborative virtual assembly.

AbstractSummaryTaxonKit is a command-line toolkit for rapid manipulation of NCBI taxonomy data. It provides executable binary files for major operating systems including Windows, Linux, and Mac OS X, and can be directly used without any dependencies nor local database buiding. TaxonKit demonstrates competitive performance in execution time compared to similar tools. The efficiency, scalability, and usability of TaxonKit enable researchers to rapidly investigate taxonomy data.AvailabilityTaxonkit is implemented in Go programming language. It is open-source and freely available for download and use from https://github.com/shenwei356/taxonkit.

A significant part of pension savings is in the capital market and exposed to market volatility. The COVID-19 pandemic crisis, like the previous crises, damaged the gains achieved in those funds. This paper presents a development of open-source finance system for stocks backtesting trade strategies. The development will be operated by the Python programming language and will implement application user interface. The system will import historical data of stocks from financial web and will produce charts for analysis of the trends in stocks price. Based on technical analysis, it will run trading strategies which will be defined by the user. The system will output the trade orders that should have been executed in retrospect and concluding charts to present the profit and loss that would occur to evaluate the performance of the strategy.

Diskless server is a cluster computer network which uses SSH (Secure Shell) protocol to grant the client an access to the host's directory and modify it's content so that the client don't need a hardisk (Thin Client). One way to design a diskless server is by utilizing "Linux Terminal Server Project", an open source-based script for Linux. However, using Linux has it own drawback, such as it can't cross platform for running an aplication based on Windows system which are commonly used. This drawback can be overcomed by using a compatibility layer that converts a windows-based application's source code. The data which will be monitored is the compatibility layer implementation's result, and the throughput, packet loss, delay, and jitter. The result of measurement from those four parameters resulting in "Excellent" for throughput, "Perfect" for packet loss and delay, and "Good" for jitter.

More and more historical data are available on the web. In France, old cadastral maps are regularly published by the “départements”. Such material is relevant to various applications (on-the-field search of specific objects such as old boundary stakes, historical studies of demography, human activities, land cover…). The GeF laboratory is working on the development of a complete methodological toolchain to vectorise, correct and analyse cadastral parcels and their evolution, using open source software and programming language only (QGIS, GDAL, Python). This article details the use of a part of this toolchain - georeferencing old cadastral data - on parcels located near the Loir river, in two villages of southern Sarthe: Vaas and Aubigné-Racan. After a presentation of our methodological toolchain, we will discuss our first results.
