Christopher Winslett: British Columbia, Time Zones, and Postgres

On March 8, 2026, British Columbia moved their clocks to a year-round Pacific Daylight Savings Time. In March, they did the spring forward one hour with their clocks to UTC-7, but they won't fall back to UTC-8 in November. Going forward, the UTC offset for America/Vancouver timezone is permanently UTC-7.Let's use this as an opportunity to talk about date and time zone storage. In the most basic examples, the default is to store the UTC value, then calculate local time relative to UTC. However...

Storage Is the Missing Piece for Agent-Built Software

Gusto, like most companies building with LLMs, is amassing a LOT of software: one-off projects, Claude Artifacts, HTML visualizations, dashboards, and my own growing fleet of personal tools.The agent loop made building 100 times easier, but deployment and operations still assume the old world. Your choices are weirdly binary:Static sites with data in the HTMLA whole app with Dockerfile, Postgres, secrets, CVE mitigation, deploy pipeline, PagerDuty, and sharp edges.When software was hard, ...

I've been on program committees for a few years now: besides prior PGDays in Chicago, I participated in the committees for PGCon...

semab tariq: How To Run Logical Replication On A Production PostgreSQL Cluster

Upgrading PostgreSQL in production is not fun. You have real data, real users, and a version of Postgres that’s probably several major releases behind. The obvious approach (dump, upgrade, restore) works fine on a 10GB database on a Saturday night. It doesn’t work when you have TBs of data, applications that can’t afford hours of downtime, and a team watching the monitoring dashboard at 2am.Logical replication solves this. I’ve run it in production, and it works well, but there are a ...

“Prag Dave” Thomas (co-author of the outstanding “Pragmatic Programmer”) has loved programming since he was young. Programming was how I could express myself. I wasn’t an artist. When I sing, dogs howl. When I draw, friends say, “Very nice. What is it?” I didn’t connect particularly well with people, even though I wanted to. And yet, when I wrote my first program, I discovered a medium which let me convert thought into action. All the ideas that were bottled up behind a wa...

Is Your Agent Playing Dead? Deployed LLM Agents Exhibit Constraint-Evasive Fabrication and Thanatosis

arXiv:2606.14831v1 Announce Type: new Abstract: This paper presents and characterizes a spectrum of previously unreported behaviours we term Constraint-Evasive Fabrication (CEF): when an LLM agent operates under irreconcilable constraints (where no response can simultaneously satisfy all active rules) it spontaneously fabricates plausible external obstacles and presents them as a fact. At the extreme end of this spectrum lies Constraint-Evasive Thanatosis (CET); the limit case where, rather ...

Running hardware-aware neural architecture search on embedded devices under 512MB of RAM

arXiv:2606.14824v1 Announce Type: new Abstract: This document proposes a novel approach to hardware-aware neural architecture search (HW NAS) that considers the resources available on the computing platform running it, enabling its execution on various embedded devices. The presented HW NAS produces tiny convolutional neural networks (CNNs) targeting low-end microcontroller units (MCUs), typically involved in the Internet of Things (IoT) or wearable robotics, opening new use cases. A gateway...

Co-Scraper: query-aware DOM Pruning and Reusable Scraper Synthesis for Lightweight Web Data Extraction

arXiv:2606.14821v1 Announce Type: new Abstract: The abundant and heterogeneous nature of web content necessitates automated information extraction, and generating scrapers that can be reused across similar web pages offers an effective solution for scalable data extraction. In this work, we propose Co-Scraper, a two-stage framework capable of handling the hierarchical complexity of long HTML documents. By integrating a query-aware DOM pruning mechanism with stable extraction strategy inducti...

Combining Retrieval-Augmented Text Generation with LLMs for Reading Content Recommendations

arXiv:2606.14817v1 Announce Type: new Abstract: This work presents the design, implementation, and evaluation of a system for generating personalized reading content using Large Language Models (LLMs) combined with Retrieval-Augmented Generation (RAG). The proposed architecture consists of four modules: Input, RAG, Generation, and Judging and enables users to specify both a question and a target reading content complexity. RAG is employed to retrieve relevant information from the Internet, e...

A Security Analysis of Long-Horizon Agentic AI Systems: Threats, Evaluation, and Framework Development

The study reviews existing threats, evaluation approaches, attack propagation mechanisms, and security frameworks. A taxonomy of security threats and a framework for analyzing attack propagation are proposed to support future research in agentic AI security

S23DR 2026: End-to-End 3D Wireframe Prediction via DETR-Style Set Prediction with Contrastive Denoising

arXiv:2606.14811v1 Announce Type: new Abstract: We present WireframeDETR, our submission to the Structured Semantic 3D Reconstruction (S23DR) 2026 Challenge, which requires predicting a 3D building wireframe from multi-view COLMAP point clouds. Our method applies DETR-style set prediction directly to 3D point clouds, producing wireframes as sets of edge coordinate pairs without any intermediate vertex detection stage. We introduce three technical contributions: (1) contrastive denoising trai...

Obligation-Producing Actions

arXiv:2606.14810v1 Announce Type: new Abstract: This paper proposes a Situation Calculus solution to the frame problem for obligation-producing actions, which are actions that create obligations on the part of the agent that performs them. As an example of such actions, we have an opening door action performed by an agent, which has the subsequent obligation of getting the door closed. Demolombe and others extend Raymond Reiter's solution to the frame problem for ordinary actions to accommod...

Knowledge-Based Zero-Replay Debugging of Multi-Agent LLM Traces

arXiv:2606.14805v1 Announce Type: new Abstract: Reliable operation of multi-agent large language model (LLM) systems depends on debugging long execution traces, where the few causally decisive events are buried in unstructured logs of messages, routes, memory writes, and tool calls. The standard tool is counterfactual replay (rewind, edit, and re-run the trajectory to measure each event's effect), but its cost grows linearly with the number of candidate events, making exhaustive replay infea...
