Rust is a young systems programming language designed to provide both the safety guarantees of high-level languages and the execution performance of low-level languages. To achieve this design goal, Rust provides a suite of safety rules and checks against those rules at the compile time to eliminate many memory-safety and thread-safety issues. Due to its safety and performance, Rust's popularity has increased significantly in recent years, and it has already been adopted to build many safety-critical software systems. It is critical to understand the learning and programming challenges imposed by Rust's safety rules. For this purpose, we first conducted an empirical study through close, manual inspection of 100 Rust-related Stack Overflow questions. We sought to understand (1) what safety rules are challenging to learn and program with, (2) under which contexts a safety rule becomes more difficult to apply, and (3) whether the Rust compiler is sufficiently helpful in debugging safety-rule violations. We then performed an online survey with 101 Rust programmers to validate the findings of the empirical study. We invited participants to evaluate program variants that differ from each other, either in terms of violated safety rules or the code constructs involved in the violation, and compared the participants' performance on the variants. Our mixed-methods investigation revealed a range of consistent findings that can benefit Rust learners, practitioners, and language designers.

Without understanding the programming difficulties faced by developers with visual impairments, the research community cannot begin to work on effective solutions to overcome these potential problems. This paper will describe our initial empirically based study to identify the problems blind software developers face. We analyzed 69 survey responses with blind developers in an effort to identify the aspects that are indeed a challenge to software development. The results indicate a number of difficulties, workarounds, and basis requirements that will serve as domain and stakeholder understand.

Integrated Development Environments (IDEs) play an important role in the workflow of many software developers, e.g. providing syntactic highlighting or other navigation aids to support the creation of lengthy codebases. Unfortunately, such complex visual information is difficult to convey with current screen-reader technologies, thereby creating barriers for programmers who are blind, who are nevertheless using IDEs. To better understand their usage strategies and challenges, we conducted an exploratory study to investigate the issue of code navigation by developers who are blind. We observed 28 blind programmers using their preferred coding tool while they performed various programming activities, in particular while they navigated through complex codebases. Participants encountered many navigation difficulties when using their preferred coding software with assistive technologies (e.g., screen readers). During interviews, participants reported dissatisfaction with the accessibility of most IDEs due to the heavy use of visual abstractions. To compensate, participants used multiple input methods and workarounds to navigate through code comfortably and reduce complexity, but these approaches often reduced their speed and introduced mistakes, thereby reducing their efficiency as programmers. Our findings suggest an opportunity for researchers and the software industry to improve the accessibility and usability of code navigation for blind developers in IDEs.

Wireless sensor networks (WSNs) have gained a lot of considerations in recent years and have significant impacts on different application areas. Wireless sensors have been successfully deployed in different computing environments to measure, gather and process the raw information in the sensing area to the observers. Sensor networks provide infinite opportunities, but at the same time pose rough challenges due to the sensors' characteristics and the operating conditions of these sensors. This paper provides an extensive study of the current state-of-art in programming wireless sensor network, presenting a classification of programming levels in the field and highlighting some likely programming challenges and research future directions.
