Developer releases open-source CeX UK price tool after bug inflated £30 case value to £136

·1 views

A developer building an eBay pricing tool discovered a bug that incorrectly attributed a £136 CeX cash offer — meant for a Raspberry Pi 500+ — to a £30 Argon ONE Pi case. The error stemmed from CeX's Algolia-powered search returning fuzzy, mismatched results rather than exact product matches. To address this, the developer built and published a standalone Python library called cex-uk-prices on GitHub under an MIT licence, which scores search results for relevance and discards weak matches below a 0.6 threshold. The tool queries CeX's Algolia index directly, since the main website returns 403 errors to server-side requests, and retrieves sell prices, cash and voucher trade-in values, and stock availability. The developer cautions that the library relies on an unofficial endpoint that may break if CeX updates its front end.

As AI Benchmarks Age and Saturate, Measuring True AI Progress Gets Harder

The launch of GPT-6 Astra, accompanied by NVIDIA CEO Jensen Huang declaring on X that 'AGI has arrived,' has reignited debate about how capable AI systems have truly become. Experts and developers quickly split between excitement and concern, with many questioning whether such milestones signal the end of software engineering as a profession. However, a closer look at AI evaluation reveals a deeper issue: benchmarks used to measure model progress can become outdated, saturated, or methodologically inconsistent over time. Astra's own system card acknowledges that some older evaluations are being retired and newer ones are adopting more realistic testing conditions, meaning a higher score does not always reflect genuinely broader capability. While AI will undoubtedly reshape software development, core engineering responsibilities such as system design, security, and architectural decision-making remain distinctly human concerns that raw benchmark numbers do not address.

How to Build an AR Fallback Governor That Protects User Camera Privacy

A developer tutorial on DEV Community outlines how to build an application-side fallback governor for Tencent RTC's Beauty AR feature, ensuring avatar failures do not silently expose a user's camera feed. The core problem addressed is that when AR effects fail due to device overheating, asset loading errors, or OS interruptions, most apps default to the raw camera — a privacy-violating substitution. The proposed governor enforces a tiered degradation ladder: quality avatar, performance avatar, sticker, and finally a paused state if camera consent has not been explicitly granted. It adapts to device capability tiers, avoids oscillating between profiles, and rejects stale async events to prevent race conditions. The tutorial argues that consent must be collected separately for each presentation mode, since switching from an avatar to a live camera feed is a fundamentally different act, not merely a quality reduction.

JQuickCurl Library Simplifies Multipart File Uploads in Java Using curl Syntax

JQuickCurl is a Java library that lets developers send multipart HTTP file uploads using familiar curl -F flag syntax, eliminating the need to manually configure OkHttp or RestTemplate multipart bodies. The library interprets the @ symbol convention to distinguish file paths from plain text form fields, then builds the corresponding multipart request over OkHttp automatically. Developers can upload single or multiple files, mix files with form metadata, and inject dynamic file paths at runtime using variable substitution in annotated interface methods. The approach keeps HTTP implementation details out of service code by expressing upload logic as a standard curl command string in a Java annotation. The library's behavior was demonstrated against the httpbin echo endpoint, which confirmed correct multipart transmission by returning uploaded file data in its response.
