Coding Beauty and Decoding Ugliness: The Role of Aesthetic Concerns in programming practices

SCIENCE TECHNOLOGY & HUMAN VALUES 2025年第1期50卷 69-93页

In this article, we analyze the productive role of aesthetics in organizing technoscientific work. Specifically, we investigate how aesthetic judgments form and inform code-writing practices at a large web services company in Russia. We focus on how programmers express aesthetic judgments about code and software design in everyday practice and explore how language with positive and negative valences is deployed. We find that programmers label code as "beautiful" without defining or establishing agreement about the term and are thereby able to maintain different ideals of beauty within the same organization. However, by learning how to avoid what senior developers deem to be "ugly" code, developers become socialized into producing code with a similar style and logic that we describe as "not ugly." The fieldwork suggests that aesthetic language can function simultaneously as a mechanism that supports professional diversity within an organization and as a tool for producing consistencies in software design. Studying manifestations of both positive and negative aesthetic language in technoscientific work provides insight into professional practices and the various roles aesthetic language can play in organizational life.

Providing timely and meaningful feedback of programming assignments to students is very important to ensure a smooth learning curve. However, this can be a time-consuming task for teachers and instructors. There are some tools that already provide support for grading programming assignments, and some are already integrated with learning management systems that allow teaching staff to manage all this information in a more effective way. In this work, an analysis of tools for automatic grading of programming assignments in Moodie is carried out. A comparison of these tools is presented and one of them is tested and recommended for its future implementation and deployment. Finally, some recommendations for further improvements are described.

Modern data centers are being transformed to meet the increased processing needs of specialized workloads with an advantageous total cost of ownership. To this end, the modular design of current microservers allows the inclusion of heterogeneous computing platforms and accelerators to enhance the performance of specific workloads, while improving the power consumption and maintenance costs of the whole system. One of the fundamental application domains for datacenters is represented by bulk data encryption and decryption, as it has to be performed on the data being stored as well as on data being transmitted or received. In this paper we investigate the OpenCL programming practices to realize high-performance FPGA accelerators, thus providing a viable and more versatile alternative to the use of ad-hoc cryptographic accelerators, which are currently available in high-end server CPUs only. We validate our analysis employing AES-128 as our case study, and report energy efficiency improvements of 22.78x with respect to pure software implementations of ISO standard block ciphers.

Block-based programming languages like Scratch, Alice and Blockly are becoming increasingly common as introductory languages in programming education. There is substantial research showing that these visual programming environments are suitable for teaching programming concepts. But, what do people do when they use Scratch? In this paper we explore the characteristics of Scratch programs. To this end we have scraped the Scratch public repository and retrieved 250,000 projects. We present an analysis of these projects in three different dimensions. Initially, we look at the types of blocks used and the size of the projects. We then investigate complexity, used abstractions and programming concepts. Finally we detect code smells such as large scripts, dead code and duplicated code blocks. Our results show that 1) most Scratch programs are small, however Scratch programs consisting of over 100 sprites exist, 2) programming abstraction concepts like procedures are not commonly used and 3) Scratch programs do suffer from code smells including large scripts and unmatched broadcast signals.

Context: Numerous factors drive long term progress in programming practices. Goal: We study the evolution of C programming in the Unix operating system. Method: We extract, aggregate, and synthesize metrics from 66 snapshots obtained from an artificial software configuration management repository tracking the evolution of the Unix operating system over four decades. Results: C language programming practices appear to evolve over long term periods;our study identified some continuous trends with highly significant coefficients of determination. Many trends point toward increasing code quality through adherence to numerous programming guidelines, while some others indicate adoption that has reached maturity. In the area of commenting progress appears to have stalled. Conclusions: Studying the long term evolution of programming practices identifies areas where progress has been achieved along an expected path, as well as cases where there is room for improvement.

Global factors shaping the future of food aid: the implications for WFP

引用

DISASTERS 2007年第Sup1期31卷 S25-S39页

作者： Maxwell, Daniel Tufts Univ Feinstein Int Ctr Medford MA 02155 USA

Food aid is a key component of a humanitarian response but its use in other programming contexts is subject to numerous criticisms. Even in humanitarian emergencies food aid is often late, unreliable and out of proportion to other elements of the response. Three major factors will shape the future of food aid. First, mechanisms of food aid governance are being reviewed and may undergo major changes-particularly the Food Aid Convention now that hopes have diminished for an Agreement on Agriculture at the World Trade Organisation. The second significant factor is donor agency trends. Overall levels of food aid have dropped fairly steadily in recent decades and there are several discernible trends in resource allocation, procurement and the use of food aid. The third factor is an emerging body of best practice that will define acceptable standards of food aid programming in the future.
