From 1 to 100 IRL events in a year: The secret to getting engineers to demo

  • PostHog grew from 1 to over 100 IRL events since summer 2025.
  • Product engineers own pricing and users, making them naturally eager to demo their work.
  • Weekly all-hands meetings include 15-20 minutes of team demos.
  • Hackathons always conclude with teams demonstrating their new features.
  • The #demo-posthog-anything channel allows employees to share demos anytime.
  • Events staff propose opportunities but do not create slides or run-throughs for speakers.
  • A custom skill analyzes GitHub activity to suggest talk topics and scores them.
  • Travel budgets, branded assets, and demo guides are provided to support speakers.
  • Most engineers enjoy speaking once they have ownership of the product being shown.

Multimodal models need video. We froze time to give it to them

  • Session recordings are rarely watched due to high volume and limited human attention.
  • Replay Vision uses multimodal AI to automate analysis instead of relying on manual review.
  • Standard session data is too large for LLMs because it lacks actual video pixels.
  • The team built a rasterizer that converts rrweb event streams into MP4 videos using headless browsers.
  • Initial attempts failed due to CPU contention causing video skips or freezes between rendering and capture processes.
  • Chrome s beginFrame mode was used to force the browser renderer to wait for frame capture before proceeding.
  • Virtual time shims were implemented in JavaScript to ensure playback advances at a steady rate regardless of real-world delays.
  • This deterministic approach allows hundreds of concurrent jobs to produce identical videos from the same input data.
  • The system has processed over 3.7 million videos since March 2026 and powers the Replay Vision platform.

Dave Stokes: Structured Query Language 101 at Texas Linuxfest

  • SQL teaches you to talk directly to databases like PostgreSQL or MySQL.
  • The session covers creating queries that select, insert, update, and delete data.
  • Learn to filter results with WHERE statements and organize them using grouping.
  • Order your lists neatly by adding simple ORDER BY commands to any query.
  • Use built-in functions to make complex tasks easy without writing extra code.

Jimmy Angelakos: 100,000 Lines of C Later: pgSafe at PGDay UK 2026

  • pgSafe re-architects enterprise PostgreSQL backups entirely in Go to allow easier community maintenance.
  • The new tool follows strict ground rules: one sealed module, no database hooks, and mandatory TDD for every change.
  • Design invariants like stop-wait-manifest ordering ensure backups remain consistent regardless of timing or hardware.
  • Credentials are scoped per worker and never stored on the database host to minimize security risk if compromised. pgSafe handles three deployment modes: simple, remote-parallel, and a dedicated worker process for maximum efficiency.
  • Although currently in alpha with fewer features than pgBackRest, it proves 100k lines of C can be reduced to ~18k.

Viacheslav Sarzhan: Percona Operator for PostgreSQL 3.1.0: Transparent Data Encryption, Logical Replicas, and Persistent Logging

  • Percona Operator PostgreSQL 3.1.0 adds transparent data encryption using pg_tde for PCI DSS compliance.
  • It introduces logical replicas to serve read-only analytics without slowing down the primary database.
  • Persistent logging keeps PostgreSQL and pgBackRest logs on disk even after Pod restarts.
  • The release also includes RKE2 support, full ARM64 images, and improved backup disk management.
  • Users can configure these features via standard custom resources without manual intervention.

Christophe Pettus: All Your GUCs in a Row: maintenance_work_mem

  • PostgreSQL uses a single memory allocation called maintenance_work_mem for specific tasks.
  • This setting acts as a fixed budget for building indexes and running vacuum operations.
  • The database cannot use extra memory beyond this limit during these processes.
  • Adjusting maintenance_work_mem directly controls how much RAM is available for index creation.
  • Higher values can speed up builds but require more physical server memory.
  • Lower values might slow down tasks while reducing overall system resource usage.

ICYMI: What landed for AI builders in August 2026

  • OpenAI s GPT-5.6 models now support millions of tokens in context with prompt caching to cut costs.
  • AWS Bedrock adds cross-region inference for global access and IAM principal cost allocation for spending visibility.
  • Security teams gain Daybreak Red/Blue tools on AWS for faster vulnerability discovery and response.
  • AgentCore runs multi-day sessions on EC2 GPUs with Temporal policies to enforce action sequences and budgets.
  • AWS GovCloud now hosts advanced models, multimodal embeddings, and agent capabilities without data retention.
  • Strands Robots links simulation demonstrations directly to physical hardware via LeRobot format and mesh discovery.

How Heurist Finance built an AI-native investment workbench on Amazon Bedrock AgentCore

  • Heurist Finance uses Amazon Bedrock AgentCore to give retail investors institutional-grade financial research.
  • The system pays for premium data per query using AgentCore payments instead of vendor contracts.
  • Amazon Bedrock AgentCore Identity and Memory automatically track user preferences without custom builds.
  • AgentCore Code Interpreter runs financial analysis in a secure sandbox that cannot access external networks.
  • This architecture delivers 80% less engineering effort than building an identical system from scratch.
  • Built-in observability lets auditors trace every decision for compliance and troubleshooting.

Simplify and support your TorchServe workloads using Ray Serve Deep Learning Containers

  • TorchServe stopped maintenance, leaving teams responsible for security patches and compatibility.
  • AWS released the Ray Serve DLC to bundle pre-tested GPU stacks without version drift.
  • The container includes PyTorch, CUDA, and utilities like FFmpeg validated together at build time.
  • Engineers can deploy vision-language models on Amazon EKS using a single-gpu node configuration.
  • Serving applications use simple Python decorators instead of TorchServe s complex handler architecture.
  • Multi-node scaling is possible by extending the foundation with KubeRay orchestration tools.
