The comment density of open source software code

This paper has statically investigated the source code of open source software (OSS) projects to uncover the presence of vulnerabilities in the code. The conducted research emphasizes that the presence of vulnerabilities has adverse effects on the overall software quality. The authors found the increasing trends in the vulnerabilities as the lines of code (LOC) increases during the software evolution. This signifies the fact that the addition of new features or change requests into the OSS project may cause an increase in vulnerability. Further, the relation between software vulnerabilities and popularity is also examined. This research does not find the existence of any relationship among software vulnerabilities and popularity. This research will provide significant implications to the developers and project managers to better understand the present state of the software.

Software Code

Abstract Knowledge spillovers in Open Source Software (OSS) can occur via two channels: In the first channel, programmers take knowledge and experience gained from one OSS project they work on and employ it in another OSS project they work on. In the second channel, programmers reuse software code by taking code from an OSS project and employing it in another. We develop a methodology to measure software reuse in a large OSS network at the micro level and show that projects that reuse code from other projects have higher success. We also demonstrate knowledge spillovers from projects connected via common programmers.

Ecg Leads

Background: We aimed to develop and validate an automated, open-source code ECG-digitizing tool and assess agreements of ECG measurements across three types of median beats, comprised of digitally recorded, simultaneous and asynchronous ECG leads, and digitized asynchronous ECG leads. Methods: We used the data of clinical studies participants (n=230; mean age 30 ± 15 y; 25% female; 52% had the cardiovascular disease) with available both digitally recorded and printed on paper and then scanned ECGs, split into development (n=150) and validation (n=80) datasets. The agreement between ECG and VCG measurements on the digitally recorded time-coherent median beat, representative asynchronous digitized, and digitally recorded beats was assessed by Bland-Altman analysis. Results: Agreement between digitally recorded and digitized representative beat was high [area spatial ventricular gradient (SVG) elevation bias 2.5(95% limits of agreement [LOA] -7.9-13.0) degrees; precision 96.8%; inter-class correlation [ICC] 0.988; Lin concordance coefficient ρc 0.97(95% confidence interval [CI] 0.95-0.98)]. Agreement between digitally recorded asynchronous and time-coherent median beats was moderate for area-based VCG metrics (spatial QRS-T angle bias 1.4(95%LOA -33.2-30.3) degrees; precision 94.8%; ICC 0.95; Lin concordance coefficient ρc 0.90(95%CI 0.82-0.95)], but poor for peak-based VCG metrics of global electrical heterogeneity. Conclusions: We developed and validated an open-source software tool for paper-ECG digitization. Asynchronous ECG leads are the primary source of disagreement in measurements on digitally recorded and digitized ECGs.

Abstract. Analysis of Software Utilization and the Role of Open-source for Abdurrab University Students. Open-source software can be acquired by downloading it for free from the internet, where the software code is published to the public or internet users. Generally, people will fix the software weaknesses and modify its display or language. Then, the repaired software is uploaded and published back to the internet. At the same time, other people will also download this open-source software application and fix other flaws. The purpose of this study was to determine the benefits and roles of open-source software for Abdurrab University students. The results of this study indicate an increase in student interest in using open-source applications and the influence, utilization, and role of open-source software for Abdurrab University students. The conclusion in this study is that open-source software still plays an important role for students because it is very helpful in various aspects to support learning.Keywords: Internet, Software, University of Abdurrab, open-sourceAbstrak.Open-source software dapat dimiliki dengan cara mengunduh secara gratis dari internet, yang mana kode software dipublikasikan ke publik atau pengguna internet. Umumnya, orang akan memperbaiki kelemahan-kelemahan software tersebut dan memodifikasi tampilan atau bahasanya. Lalu, software yang diperbaiki tersebut diunggah dan dipublikasikan kembali ke internet. Pada saat yang sama, orang lain juga akan mengunduh aplikasi software open-source ini dan memperbaiki kelemahan-kelemahan lain. Tujuan dari penelitian ini adalah mengetahui manfaat dan peran open-source software bagi mahasiswa Universitas Abdurrab. Hasil penelitian ini memperlihatkan adanya peningkatan minat mahasiswa dalam menggunakan aplikasi open-source dan pengaruh, pemanfaatan, serta peran software open-source bagi mahasiswa Universitas Abdurrab. Kesimpulan pada penelitian ini ialah open-source software masih berperan penting bagi mahasiswa karena sangat membantu dalam berbagai aspek untuk mendukung pembelajaran.Kata Kunci: Internet, Software, Universitas Abdurrab, open-source

Software Code

Systematic mapping assesses the nature of an evidence base, answering how much evidence exists on a particular topic. Perhaps the most useful outputs of a systematic map are an interactive database of studies and their meta-data, along with visualisations of this database. Despite the rapid increase in systematic mapping as an evidence synthesis method, there is currently a lack of Open Source software for producing interactive visualisations of systematic map databases. In April 2018, as attendees at and coordinators of the first ever Evidence Synthesis Hackathon in Stockholm, we decided to address this issue by developing an R-based tool called EviAtlas, an Open Access (i.e. free to use) and Open Source (i.e. software code is freely accessible and reproducible) tool for producing interactive, attractive tables and figures that summarise the evidence base. Here, we present our tool which includes the ability to generate vital visualisations for systematic maps and reviews as follows: a complete data table; a spatially explicit geographical information system (Evidence Atlas); Heat Maps that cross-tabulate two or more variables and display the number of studies belonging to multiple categories; and standard descriptive plots showing the nature of the evidence base, for example the number of studies published per year or number of studies per country. We believe that EviAtlas will provide a stimulus for the development of other exciting tools to facilitate evidence synthesis.
