PostgreSQL HA Risks, Replication Internals, & Rapid Branching Today's Highlights Today's highlights include critical insights into Patroni's replication slot management, an architectural deep dive into PostgreSQL's synchronous commit behavior, and a look at achieving sub-second database branching for enhanced developer workflows. When Patroni Silently Deletes Your Replication Slots (Planet PostgreSQL) Source: https://postgr.es/p/9lM This article uncovers a critical operational pitfall when using Patroni, a popular high-availability solution for PostgreSQL, with logical replication. It details how Patroni, under specific failure scenarios or configuration changes, can silently remove replication slots without warning. Replication slots are vital for ensuring that standbys or logical replication consumers do not miss any changes, making their deletion a potentially severe data integrity issue. The author explains the underlying reasons for this behavior, often related to how Patroni manages pg_basebackup or restores, and how it might not re-create logical replication slots automatically. The post provides concrete scenarios where this can occur, such as when a new primary is elected and old slots aren't re-established, or during certain recovery operations. It emphasizes the importance of diligent monitoring of replication slot status and proposes strategies to mitigate the risk of silent deletion, including careful Patroni configuration and robust alerting mechanisms. This insight is crucial for database administrators and developers relying on Patroni for resilient PostgreSQL deployments, highlighting a subtle but dangerous interaction between these two powerful components. Comment: This is a must-read for anyone running Patroni with PostgreSQL, especially if using logical replication. Understanding this specific behavior of Patroni deleting replication slots silently is essential to prevent unexpected data loss or integrity issues in production. Why Postgres Doesn'

A solo developer with a $200/month budget can now access the same AI coding power that cost enterprises $50,000/month just two years ago. The secret isn't one tool — it's knowing how to mix and match three different access models to get frontier output at budget prices. I've been running this exact stack for months. Here's the breakdown. The Three Ways to Access AI Coding Models Before we talk strategy, understand your three options. Each has a wildly different cost profile. Option 1: Self-Hosted Open Models With models like GLM-5.2 hitting near-Claude Opus quality under MIT license, self-hosting is finally viable. The math is straightforward. Hardware cost: A dedicated GPU server (RTX 4090 or A100) runs $300–$800/month. An H100 rental starts at $1.99/hour on platforms like RunPod. Break-even point: According to cost analysis from multiple providers, self-hosting becomes cheaper than APIs at roughly 5–10 million tokens per month for premium-tier models [1]. Below that volume, you're paying for idle hardware. The catch: You need DevOps skills. Model deployment, quantization, monitoring, failover — it's real infrastructure work. If you save $500 on compute but burn out managing GPUs on weekends, you lost money. Best for: Teams with predictable, high-volume workloads and existing DevOps capability. Think 100M+ tokens/month where savings hit $5M+ annually [2]. Option 2: Pay-Per-Token APIs The default starting point. You pay exactly for what you use. Current pricing (early 2026, per 1M tokens): GPT-4o: $2.50 input / $10.00 output Claude 3.5 Sonnet: $3.00 input / $15.00 output Gemini 1.5 Pro: $1.25 input / $5.00 output DeepSeek V3: $0.27 blended (yes, really) Together AI (Llama 70B): $0.88 blended [1] The pricing floor crashed when DeepSeek V3 arrived at $0.27/M tokens with GPT-4-class quality. Open-source models routed through providers like Together AI or Cerebras ($6–12/M tokens at 969 tok/s) give you more options than ever. The trap: Pricing scales linearly forever. A

Building a Game with Zero Assets in Godot This is the first game I've ever made. I'm not a developer by trade, I'd never touched Godot before, and I leaned on AI to help me get over the learning curve. But I gave myself one hard rule that ended up shaping the entire project: Zero external assets. No textures. No sprite sheets. No audio files. No music files. The whole repository contains none of them. Everything you see and hear in Reactor Panic - a small arcade game where you sort plasma cores before the reactor melts down - is generated at runtime in code. Here's how I did it, including the parts that went badly wrong. Why do this to myself? Two reasons. First, I can't draw or compose, so "make it all procedural" was weirdly easier than sourcing, creating, and licensing art assets. Second, and this is the part I didn't expect, when everything is code, everything can react to the game state for free. More on that later. Drawing the Reactor All of the 2D art is rendered using Godot's _draw() function. The most involved piece is the containment dome. It isn't a sprite at all - it's shaded per cell like a tiny software renderer. For each cell, I compute a hemisphere surface normal, perform Lambertian diffuse lighting with a specular hotspot, add Fresnel-style rim darkening, and then quantise the result into a handful of discrete steel bands so it reads as pixel art rather than a smooth gradient. # Hemisphere surface normal var sx : = ( mid_x - center_x ) * inv_half_w var sz : = sqrt ( maxf ( 0.0 , 1.0 - sx * sx - sy_sq )) var norm : = Vector3 ( - sx , sy , sz ) . normalized () # Lambertian diffuse var ndotl : = maxf ( 0.0 , norm . dot ( light3 )) var light_val : = 0.1 + ndotl * 0.9 # Fresnel rim darkening (surface curving away from viewer goes dark) light_val *= lerpf ( 0.4 , 1.0 , clampf ( sz * 1.8 , 0.0 , 1.0 )) # Quantise into discrete shade bands -> reads as pixel art var band : = clampi ( int ( round ( light_val * max_band_f )), 0 , num_bands - 1 ) var col : Colo

You scan one to pay at a sari-sari store, pull up a restaurant menu, or board a flight. The QR code has quietly become one of the most universal pieces of interface design on the planet. But it was never meant for any of that. The QR code was invented in 1994 to solve a very specific problem on a Japanese car factory floor, and the engineering decisions made under that constraint are exactly why it later conquered the world. A barcode problem on the assembly line In the early 1990s, Toyota's manufacturing arm had a data problem. Tracking thousands of distinct components through production meant scanning barcodes, and barcodes are stingy: a standard one-dimensional barcode holds roughly 20 characters. Workers were ending up with parts plastered in ten or more barcodes just to encode enough information, and each one had to be scanned separately. It was slow, and on an assembly line, slow is expensive. Masahiro Hara, an engineer at Denso Wave, a Toyota subsidiary, took on the challenge of designing something better. He wanted a code that could hold far more data, be read much faster, and tolerate the dirt, smudges, and odd angles of a real factory rather than a clean lab. Designing for speed and any angle The breakthrough was going two-dimensional. By encoding data in a grid of black and white squares rather than a single row of lines, Hara's team could pack in thousands of characters instead of a few dozen. The name they chose, QR for "Quick Response," was a direct promise about scanning speed. The most recognizable feature of a QR code, the three large squares in its corners, solves the hardest part of the problem: letting a scanner instantly find the code and work out its orientation no matter how the part is turned. Hara's team analyzed printed material to find a black-and-white sequence that almost never occurs naturally in text and images, and settled on a ratio of 1:1:3:1:1 for those corner markers. Because that pattern is so rare in everyday print, a scanner ca
