7Home Depot sued for 'secretly' using facial recognition at self-checkouts
- A Home Depot customer has filed a class action lawsuit against the company, claiming they secretly use facial recognition technology at self-checkout kiosks that scans customers' faces without consent. The lawsuit alleges this violates Illinois privacy laws and seeks compensation for affected shoppers.
Loss prevention effectiveness
Debate over aggressive store security tactics, with many noting LP staff target innocent customers while avoiding confronting actual thieves. Discussion of stores building cases over time vs immediate intervention.Self-checkout impact
Mixed views on self-checkout - some see it as dehumanizing retail and eliminating jobs, while others value the efficiency. Debate over whether customers should be compensated for doing checkout work themselves.Face detection concerns
Discussion of legal and privacy implications of facial recognition tech in stores, including whether simple face detection counts as biometric data collection and how stores may use this data to track customers.
8Code review can be better
- The article discusses an experimental tool called git-review that aimed to improve code review processes by storing review comments directly in code repositories, rather than using web interfaces. While the basic concept showed promise, implementation challenges and complexities led to shelving the project for now.
