During these sessions, candidates must write code while thinking aloud as they work toward a solution to a problem under the watchful eye of an interviewer. While thinking aloud during technical interviews gives interviewers a picture of candidates’ problem-solving ability, surprisingly, these types of interviews often prevent candidates from communicating their thought process effectively. To understand if poor performance related to interviewer presence can be reduced while preserving communication and technical skills, we introduce asynchronous technical interviews—where candidates submit recordings of think-aloud and coding. We compare this approach to traditional whiteboard interviews and find that, by eliminating interviewer supervision, asynchronicity significantly improved the clarity of think-aloud via increased informativeness and reduced stress. Moreover, we discovered asynchronous technical interviews preserved, and in some cases even enhanced, technical problem-solving strategies and code quality. This work offers insight into asynchronous technical interviews as a design for supporting communication during interviews, and discusses trade-offs and guidelines for implementing this approach in software engineering hiring practices.","PeriodicalId":68155,"journal":{"name":"软件产业与工程","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84225166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identifying, understanding, and classifying such uncertainties are essential to enable system designers to reason about uncertainties and subsequently develop solutions for empowering elevator systems to deal with uncertainties systematically. To this end, we present a method, called RuCynefin, based on the Cynefin framework to classify uncertainties in industrial elevator systems from our industrial partner (Orona, Spain), results of which can then be used for assessing their robustness. RuCynefin is equipped with a novel classification algorithm to identify the Cynefin contexts for a variety of uncertainties in industrial elevator systems, and a novel metric for measuring the robustness using the uncertainty classification. We evaluated RuCynefin with an industrial case study of 90 dispatchers from Orona to assess their robustness against uncertainties. Results show that RuCynefin could effectively identify several situations for which certain dispatchers were not robust. Specifically, 93% of such versions showed some degree of low robustness against uncertainties. We also provide insights on the potential practical usages of RuCynefin, which are useful for practitioners in this field.","PeriodicalId":68155,"journal":{"name":"软件产业与工程","volume":"7 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83974428","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result, the different products in the product line may drift apart, which implies increased efforts for tasks such as change propagation, domain analysis, and quality assurance. While many solutions have been proposed in the literature, these are often difficult to apply in a real-world setting. We study this drift of products in a concrete large-scale industrial model-driven clone-and-own software product line in the railway domain at our industry partner. For this purpose, we conducted interviews and a survey, and we investigated the models in the model history of this project. We found that increased efforts are mainly caused by large model differences and increased communication efforts. We argue that, in the short-term, treating the symptoms (i.e., handling large model differences) can help to keep efforts for software product-line engineering acceptable — instead of employing sophisticated variability management. To treat the symptoms, we employ a solution based on semantic-lifting to simplify model differences. Using the interviews and the survey, we evaluate the feasibility of variability management approaches and the semantic-lifting approach in the context of this project.","PeriodicalId":68155,"journal":{"name":"软件产业与工程","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80308372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the code commit history, RegMiner searches for regressions where a test can pass a regression-fixing commit, fail a regressioninducing commit, and pass a previous working commit again. Technically, RegMiner (1) identifies potential regression-fixing commits from the code evolution history, (2) migrates the test and its code dependencies in the commit over the history, and (3) minimizes the compilation overhead during the regression search. Our experients show that RegMiner can successfully collect 1035 regressions over 147 projects in 8 weeks, creating the largest replicable regression dataset within the shortest period, to the best of our knowledge. In addition, our experiments further show that (1) RegMiner can construct the regression dataset with very high precision and acceptable recall, and (2) the constructed regression dataset is of high authenticity and diversity.

Because OSS projects are socio-technical systems centered around code artifacts, we hypothesize that sustainable projects may exhibit different code and process patterns than unsustainable ones, and that those patterns can grow more apparent as projects evolve over time. Here we studied the code and coding processes of over 200 ASFI projects, and found that ASFI graduated projects have different patterns of code quality and complexity than retired ones. Likewise for the coding processes – e.g., feature commits or bug-fixing commits are correlated with project graduation success. We find that minor contributors and major contributors (who contribute <5%, respectively >=95% commits) associate with graduation outcomes, implying that having also developers who contribute fewer commits are important for a project’s success. This study provides evidence that OSS projects, especially nascent ones, can benefit from introspection and instrumentation using multidimensional modeling of the whole system, including code, processes, and code quality measures, and how they are interconnected over time.","PeriodicalId":68155,"journal":{"name":"软件产业与工程","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73842940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For many programs in these domains it is consequential to analyze aspects like security and performance, and with Python’s dynamic nature, it is crucial to be able to dynamically analyze Python programs. However, existing tools and frameworks do not provide the means to implement dynamic analyses easily and practitioners resort to implementing an ad-hoc dynamic analysis for their own use case. This work presents DynaPyt, the first general-purpose framework for heavy-weight dynamic analysis of Python programs. Compared to existing tools for other programming languages, our framework provides a wider range of analysis hooks arranged in a hierarchical structure, which allows developers to concisely implement analyses. DynaPyt features selective instrumentation and execution modification as well. We evaluate our framework on test suites of 9 popular open-source Python projects, 1,268,545 lines of code in total, and show that it, by and large, preserves the semantics of the original execution. The running time of DynaPyt is between 1.2x and 16x times the original execution time, which is in line with similar frameworks designed for other languages, and 5.6%–88.6% faster than analyses using a built-in tracing API offered by Python. We also implement multiple analyses, show the simplicity of implementing them and some potential use cases of DynaPyt. Among the analyses implemented are: an analysis to detect a memory blow up in Pytorch programs, a taint analysis to detect SQL injections, and an analysis to warn about a runtime performance anti-pattern.","PeriodicalId":68155,"journal":{"name":"软件产业与工程","volume":"49 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80950064","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, despite its popularity, it is a challenging task to correctly understand the behaviors of JavaScript programs because of their highly dynamic nature. Researchers have developed various static analyzers that strive to conform to ECMA-262, the standard specification of JavaScript. Unfortunately, all the existing JavaScript static analyzers require manual updates for new language features. This problem has become more critical since 2015 because the JavaScript language itself rapidly evolves with a yearly release cadence and open development process. In this paper, we present JSAVER, the first tool that automatically derives JavaScript static analyzers from language specifications. The main idea of our approach is to extract a definitional interpreter from ECMA-262 and perform a meta-level static analysis with the extracted interpreter. A meta-level static analysis is a novel technique that indirectly analyzes programs by analyzing a definitional interpreter with the programs. We also describe how to indirectly configure abstract domains and analysis sensitivities in a meta-level static analysis. For evaluation, we derived a static analyzer from the latest ECMA-262 (ES12, 2021) using JSAVER. The derived analyzer soundly analyzed all applicable 18,556 official conformance tests with 99.0% of precision in 590 ms on average. In addition, we demonstrate the configurability and adaptability of JSAVER with several case studies.","PeriodicalId":68155,"journal":{"name":"软件产业与工程","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87569201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our goal was to understand the factors that influenced the time a change, ie a diff at Meta, would spend in review. A developer survey showed that diff reviews start to feel slow after they have been waiting for around 24 hour review. We built a review time predictor model to identify potential factors that may be causing reviews to take longer, which we could use to predict when would be the best time to nudge reviewers or to identify diff-related factors that we may need to address. The strongest feature of the time spent in review model we built was the day of the week because diffs submitted near the weekend may have to wait for Monday for review. After removing time on weekends, the remaining features, including size of diff and the number of meetings the reviewers have did not provide substantial predictive power, thereby not being able to predict how long a code review would take. We contributed to the effort to reduce stale diffs by suggesting that diffs be nudged near the start of the workday and that diffs published near the weekend be nudged sooner on Friday to avoid waiting the entire weekend. We use a nudging threshold rather than a model because we showed that TimeInReview cannot be accurately modelled.
