Pasta Inspector: Offline Camera Detects 3D Print Failures on Klipper Printers

0
·7 views

Pasta Inspector is a work-in-progress, source-available project that uses a small ESP32-S3 camera or any USB webcam to spot failed 3D prints on Klipper-based printers. It runs fully offline with no cloud or accounts, connecting to Moonraker over WiFi or USB. The system compares the camera view against the G-code's object outlines to decide which part failed. If it is confident, it excludes only that object and lets the rest finish; otherwise it pauses the print. The developers stress it is a proof of concept, tested only on simulated prints so far, and not a safety device.

Changing One Postgres Planner Setting From 32 to 34 Cut a Slow Query's Runtime Nearly 6,000-Fold

A developer's reporting query, built on several layers of nested views, took over two minutes to run in Postgres. The slow plan came from the planner's join_collapse_limit setting, which controls how joins are grouped before unneeded ones are removed. Testing values from 8 to 140 showed the fast and slow plans alternate in a non-monotonic pattern, with a value of 32 taking about 140 seconds and 34 taking 23.9 milliseconds. The root cause was that the planner built a costly inner join and ran it 181 times, based on a row estimate of 1 that was far off from the actual count of 181. The article then explains how views are expanded into large numbers of table references and when Postgres can remove redundant LEFT JOINs.

AI Agents Are Gaining Business Roles, But Only Under Human Supervision

Surveys show AI agents are being used in customer support, sales, finance, and IT, though most organisations remain in experimentation stages. McKinsey's 2025 research found no more than 10% of organisations are scaling agents within any single business function. Agents are described as systems that pursue goals, plan steps, use tools, check their work, and escalate exceptions to humans. Experts stress that permissions, identity tracking, approval tiers, and audit logs are essential safeguards rather than optional overhead. Sensitive areas such as hiring, credit decisions, medical treatment, and legal commitments are considered unsuitable for autonomous agents for now.

New beginner coding series explains what a program is in its first installment

A new beginner-friendly series called Cuppa and Code has launched on DEV Community. Its first installment, published November 1 by Amy Hudspith, answers the question of what a program is. The episode is designed to take roughly ten minutes and introduces coding basics using Python and Jupyter. It is aimed at readers with little or no programming experience and is tagged as a tutorial.

Developer details lessons from building an AI-edited Android launcher with Claude Code

The author built AI Launcher, an open-source Android home screen designed to be modified by an AI coding agent that edits code, installs it, and checks results. Claude Code wrote most of the code while the author directed it and tested on real phones. A build passed all automated checks yet showed a black clock on a black background, which only a screenshot revealed, so the definition of done now requires both a passing verify script and visual review. Fresh agent sessions exposed gaps in the project's instructions, and a verify script that cleared phone logs was changed so scripts leave device state as they found it. Key input also caused the pager to focus off-screen pages, which was fixed by no longer composing those pages. The project has only been tested on two Samsung phones using Claude Code on Linux, and it currently requires a computer and coding agent since no APK is available yet.
