Academic publications have been evaluated with the impact on research communities based on the number of citations. On the other hand, the impact of academic publications on industry has been rarely studied.
This paper investigates how academic publications contribute to software development by analyzing publication citations in source code comments in open source software repositories.
We propose an automated approach of detecting academic publications based on Named Entity Recognition, and achieve 0.90 in F1 as detection accuracy. We conduct a large-scale study of publication citations with 319,438,977 comments collected from active 25,925 repositories written in seven programming languages.
Our findings indicate that academic publications can be knowledge sources of software development, and there can be potential issues of obsoleting knowledge.

In the very broad scope addressed by digital preservation initiatives, a special place belongs to the scientific and technical artifacts that we need to properly archive to enable scientific reproducibility.
For these artifacts we need identifiers that are not only unique and persistent, but also support integrity in an intrinsic way. They must provide strong guarantees that the object denoted by a given identifier will always be the same, without relying on third parties and external administrative processes.
In this article, we report on our quest for this identifiers for digital objects (IDOs), whose properties are different from, and complementary to, those of the various digital identifiers of objects (DIOs) that are in widespread use today.
We argue that both kinds of identifiers are needed and present the framework for intrinsic persistent identifiers that we have adopted in Software Heritage for preserving billions of software artifacts.

Software is now a key component present in all aspects of our society. Its preservation has attracted growing attention over the past years within the digital preservation community.
We claim that source code—the only representation of software that contains human readable knowledge—is a precious digital object that needs special handling: it must be a first class citizen in the preservation landscape and we need to take action immediately, given the increasingly more frequent incidents that result in permanent losses of source code collections. In this paper we present Software Heritage, an ambitious initiative to collect, preserve, and share the entire corpus of publicly accessible software source code.
We discuss the archival goals of the project, its use cases and role as a participant in the broader digital preservation ecosystem, and detail its key design decisions. We also report on the project road map and the current status of the Software Heritage archive that, as of early 2017, has collected more than 3 billion unique source code files and 700 million commits coming from more than 50 million software development projects.
