pg_durable: Microsoft open sources in-database durable execution
Long-running, fault-tolerant SQL functions for teams that already keep their state in Postgres and want to stop stitching together cron jobs, workers, queues, and status tables to make background work reliable. Define the workflow in SQL, let pg_durable checkpoint each step, and resume after crashes, restarts, or failed steps. Durable execution is now a standard industry pattern, and pg_durable brings it inside Postgres with no extra service infrastructure required.
Validation of graph databases against PG-Schema
Computer Science > Databases [Submitted on 4 Jun 2026] Title:Validation of graph databases against PG-Schema View PDF HTML (experimental)Abstract:The problem of validating a given graph database instance against a given PG-Schema graph type without integrity constraints is NP- complete in terms of combined complexity and in PTIME in terms of data complexity. The combined complexity drops to PTIME when the alternation between type combinations and unions is suitably restricted References &...
You can make the hyper-violence in Marvel's Wolverine more PG-13, if you want to
You can make the hyper-violence in Marvel’s Wolverine more PG-13, if you want to And Robert Rodriguez wept. If you're a fan of Wolverine, you probably know to expect some gore whenever he shows up. And if you watched this week's trailer for Insomniac's upcoming PS5 game, well, let's just say it earned its M rating.
GPU accelerated population genetics statistics using pg_gpu
Population genetics summary statistics-- diversity, divergence, linkage disequilibrium, selection scans, and dimensionality reduction-- are fundamental across human, agricultural, and ecological genomics. As whole-genome sequencing datasets have grown to hundreds of thousands of individuals, the cost of computing these statistics on conventional CPU implementations has become a major bottleneck: windowed scans of a single chromosome arm can take hours to days, and computation of pairwise...
Decades of Effort Restore Steelhead and Salmon Passage on Alameda Creek
Last year, California Trout and Pacific Gas & Electric removed the final barrier to fish passage on California’s Alameda Creek with funding from NOAA Fisheries’ Office of Habitat Conservation. For the first time in 50 years, threatened Central California Coast steelhead and other migratory fish can reach spawning grounds and juvenile rearing habitat in the upper watershed. Construction crews relocated a Pacific Gas & Electric (PG&E) natural gas pipeline and removed its concrete covering.
Reusing Trajectories in Policy Gradients Enables Fast Convergence
Announce Type: replace Abstract: Policy gradient (PG) methods are a class of effective reinforcement learning algorithms, particularly when dealing with continuous control problems. They rely on fresh on-policy data, making them sample-inefficient and requiring $O(\epsilon^{-2})$ trajectories to reach an $\epsilon$-approximate stationary point.
GuidedBridge: Training-freely Improving Bridge Models with Prior Guidance
arXiv:2606.03119v1 Announce Type: new Abstract: Guidance methods, such as classifier-free guidance (CFG) and auto-guidance (AG), have advanced noise-to-data generation in diffusion models. Recently, bridge models have introduced a data-to-data generative process that can exploit an instructive clean prior. In this work, inspired by previous methods creating quality difference between denoising results as guidance, we propose a training-free bridge guidance method, termed Prior Guidance (PG).
Over two dozen BEd candidates injured as drain cover collapses outside Kanpur exam centre
Around two dozen candidates appearing for the Uttar Pradesh BEd Joint Entrance Examination fell into a sewage drain after a damaged concrete slab collapsed outside an examination centre in Kanpur on Sunday morning, police said. The incident took place near HN Mishra PG College in MacRobertganj, where candidates had gathered near a photocopy shop before entering the examination centre. According to officials and eyewitnesses, the concrete slab covering the drain gave way under the weight of...
Brunson or Wemby: Who tops our rankings of the pla...
An NBA postseason highlighted by breakout performances, Game 7 thrillers and more than a few upsets has reached its last chapter: The Finals between the San Antonio Spurs and New York Knicks. San Antonio is seeking its first championship since 2014 after winning 62 games during the regular season and dethroning the Oklahoma City Thunder in the Western Conference finals. New York, ringless since 1973, won 53 games and the NBA Cup before breezing through the Eastern Conference playoffs with a...
Effects of spatially localised pressure gradient histories on recovery of turbulent boundary layers
arXiv:2510.16184v4 Announce Type: replace Abstract: Hot-wire anemometry is used to investigate the recovery of smooth-wall turbulent boundary layers from spatially localised (i.e. impulsive) pressure gradient history (PGH) effects. Measurements are performed at multiple stations downstream of spatial distributions of favourable-adverse pressure gradient sequences, followed by relaxation to zero-pressure-gradient (ZPG) conditions. The analysis focuses on matched friction Reynolds numbers at...
