Integrating WorkOS AuthKit Authentication in Rust axum: A Practical Guide
Based on WorkOS's official blog, this article explains how to integrate WorkOS AuthKit into a Rust axum app: use the Rust SDK for login, validate user sessions on every request, and verify webhook signatures, with integration insights and practical tips.
Tech FrontiersPushing the Limits of Extreme Sudoku on a 16GB GPU: Insights from Depth and Flow Matching
A researcher trained a 16.54M-parameter model on a 16GB GPU to solve extreme Sudoku, finding effective depth breaks the 60% plateau and flow matching with improved sampling pushes accuracy past 99% with ~50× lower layer-evaluation budget.
A New Proof on the Closedness of ReLU Network Sets: Single Hidden Layer is Weakly Closed, Two Hidden Layers is Not Closed
New research proves single-hidden-layer ReLU network sets are weakly closed in W^{1,p}, ensuring existence of solutions for Deep Ritz and similar methods; two-hidden-layer network sets are not closed, refuting an existing conjecture.
FlowMoP: A New Framework for Stochastic Multi-Person Motion Prediction
FlowMoP introduces a conditional flow matching framework that jointly generates diverse future motions for multiple agents, using B-spline reparameterization and a dual-stream Transformer for interaction-aware prediction. It outperforms deterministic baselines on CMU-Mocap and 3DPW and establishes the first motion prediction baseline on WorldPose.
Computer-Using Agents: A New General-Purpose Paradigm for Embodied AI
ECCV workshop competitions show computer-using agents (CUAs) can win multiple contests by turning embodied tasks into software interaction, without specialized tuning—revealing their potential as embodied generalists and a new path to general embodied AI.
Graded Convolutional Networks: Scale Invariance and Blur Robustness Without Scale Parameters
Graded Convolutional Networks leverage the graded vector space structure of Gaussian jets to achieve scale invariance via retraction without scale parameters, significantly improving robustness under unknown Gaussian blur. MNIST experiments show 88.4% accuracy under two-pixel blur, outperforming scale-normalized derivatives at 66.2%.
UCR Archive Exposed? 52 Pigs Reveal the Truth About TSC Benchmarks
Audit of the UCR time series classification archive: multiple datasets have repurposed tasks and flawed test splits. The 52-pig dataset reveals TSC benchmarks are disconnected from real problems, urging cautious interpretation of archive scores.
How to Design Effective Monitor-Based Interventions to Curb Reward Hacking in RL
Research reveals design principles for monitor-based interventions against reward hacking in RL: models can evade high-precision monitors; monitors that leak more learning signal suppress hacking better but are easier to evade; mixing simpler problems into training reduces reward hacking. Three open-source environments—coding, medical chat, and biography generation—show findings transfer to new settings.
The 19-Year-Old PayPal Mafia Dream: How Competition Kids Became the Backbone of AI
A tweet recalls a 2017 San Francisco lunch where 19-year-old Scott Wu and friends imagined the competition circle becoming the next PayPal Mafia. Nearly a decade later, these kids from MATHCOUNTS and AoPS are scattered across AI's core, showing how high-density peer communities cultivate top talent.
