| Abstract | Technical debt is a metaphor introduced by Cunningham to indicate "not quite right code which we postpone making it right". Examples of technical debt are code smells and bug hazards. Several techniques have been proposed to detect different types of technical debt. Among those, Potdar and Shihab defined heuristics to detect instances of self-admitted technical debt in code comments, and used them to perform an empirical study on five software systems to investigate the phenomenon. Still, very little is known about the diffusion and evolution of technical debt in software projects. This paper presents a differentiated replication of the work by Potdar and Shihab. We run a study across 159 software projects to investigate the diffusion and evolution of self-admitted technical debt and its relationship with software quality. The study required the mining of over 600K commits and 2 Billion comments as well as a qualitative analysis performed via open coding. Our main findings show that self-admitted technical debt (i) is diffused, with an average of 51 instances per system, (ii) is mostly represented by code (30%), defect, and requirement debt (20% each), (iii) increases over time due to the introduction of new instances that are not fixed by developers, and (iv) even when fixed, it survives long time (over 1,000 commits on average) in the system. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
