A deep study of the effects and fixes of server-side request races in web applications

Qiu, Z., Shao, S., Zhao, Q., Khan, H. A., Hui, X., & Jin, G. (2022, May 23).

By: Z. Qiu n, S. Shao n, Q. Zhao n , H. Khan n, X. Hui n & G. Jin n

author keywords: web-application request races; characteristic study; Object-Relational Mapping; external and internal effects; fix strategies
topics (OpenAlex): Software System Performance and Reliability; Distributed systems and fault tolerance; Cloud Computing and Resource Management
TL;DR: This study reveals that request races from ORM-based web applications share the same characteristics as those from raw-SQL web applications, and request races violating application semantics without explicit crashes and error messages externally are common, and latent request races are also common.

Left or Right: A Peek into the Political Biases in Email Spam Filtering Algorithms During US Election 2020

Iqbal, H., Khan, U. M., Khan, H. A., & Shahzad, M. (2022, April 25). Proceedings of the ACM Web Conference 2022.

By: H. Iqbal n, U. Khan n, H. Khan n & M. Shahzad n 

author keywords: US Elections; Emails; Spam; Bias; Political Bias; Algorithm Bias
topics (OpenAlex): Spam and Phishing Detection; Internet Traffic Analysis and Secure E-voting; Privacy, Security, and Data Protection
TL;DR: It is observed that the SFAs of different email services indeed exhibit biases towards different political affiliations, and the impact of the interactions (such as reading or marking emails as spam) of email recipients on these biases is studied. (via Semantic Scholar)

RMS: Removing Barriers to Analyze the Availability and Surge Pricing of Ridesharing Services

Khan, H. A., Iqbal, H., Shahzad, M., & Jin, G. (2022, April 28). CHI Conference on Human Factors in Computing Systems.

By: H. Khan n, H. Iqbal n, M. Shahzad n  & G. Jin n

author keywords: Ridesharing services; Gig economy; Uber; Surge; COVID 19
topics (OpenAlex): Transportation and Mobility Innovations; Sharing Economy and Platforms; Urban Transport and Accessibility
TL;DR: This paper identifies that previous articles miscalculated the utilization of ridesharing services as they did not count in the vehicles driving in multiple categories of the same service, and presents Ridesharing Measurement Suite (RMS), which removes the barrier of entry for analyzing the availability and surge pricing of ridesHaring services for ridesh sharing users, researchers from various scientific domains, and regulators.

Understanding and Reaching the Performance Limit of Schedule Tuning on Stable Synchronization Determinism

Zhao, Q., Qiu, Z., Shao, S., Hui, X., Khan, H. A., & Jin, G. (2022, October 8).

By: Q. Zhao n , Z. Qiu n, S. Shao n, X. Hui n, H. Khan n & G. Jin n

author keywords: stable synchronization determinism; performance limit; synchronization scheduling; scheduling-oblivious overheads; totally-ordered synchronization; workload-length imbalance
topics (OpenAlex): Distributed systems and fault tolerance; Parallel Computing and Optimization Techniques; Distributed and Parallel Computing Systems
TL;DR: It is concluded that minSMT successfully reaches the performance limit of stable synchronization determinism on 107 out of 108 benchmarks after excluding the impact of scheduling-oblivious overheads, and this also results in significant performance improvements compared with state-of-the-art stable synchronization-determinism systems on 9 benchmarks.
