Engineer creates holograms using a pen plotter in DIY experiment

·1 views

A maker has documented a method for producing holograms using a pen plotter, a device traditionally used for drawing vector graphics. The project, shared on a personal blog, explores how precise mechanical line patterns can generate holographic visual effects. The technique combines principles of optics and computer-controlled drawing to achieve the result. The write-up has attracted attention on Hacker News as an unconventional application of widely available hardware.

How to Build an Enterprise Autonomous Web Agent SaaS Using TypeScript

A new technical guide outlines how to architect an enterprise-grade autonomous web agent Software-as-a-Service platform using TypeScript. The piece addresses the growing demand from enterprises for intelligent systems that can interpret natural language directives, navigate dynamic web interfaces, and construct their own execution paths in real time. The guide draws an architectural parallel between microfrontend web applications and multi-agent systems, mapping components like API gateways to supervisor nodes and microfrontends to specialized worker agents. Key engineering challenges covered include preventing context degradation in long browsing sessions, isolating tenant states in distributed cloud environments, and maintaining compliance without sacrificing speed. The article provides theoretical foundations, architectural blueprints, and production-ready TypeScript code for building such a system from the ground up.

AI Agents Expose a Long-Standing Gap in Non-Human Identity Security

As agentic AI systems like autonomous code assistants and orchestrators gain rapid adoption in 2025-2026, security experts warn that non-human identity (NHI) governance is being neglected. AI agents, like CI workers and service accounts before them, authenticate and connect to sensitive systems — yet are frequently granted broad, standing permissions via long-lived static secrets such as API keys. When these credentials leak, attackers can access everything the secret permits until the breach is detected. The core issue mirrors longstanding NHI security failures: authentication and authorization are not properly separated, violating zero-trust principles. Treating AI agents as accountable actors with scoped, time-limited permissions — similar to human employees — is proposed as a practical path toward closing this governance gap.

GitX tool organizes AI-generated code changes into clean, logical Git commits

A developer has released GitX, an open-source Git workflow tool designed to bring order to the messy working trees that AI coding agents like Codex, Claude Code, and Cursor often leave behind. After AI sessions that can touch dozens of files spanning features, bug fixes, tests, and documentation, GitX analyzes the changes and proposes how they should be grouped into separate, logically named commits before anything is written. The tool follows the Conventional Commits format and supports a broader workflow through commands covering branching, pull request creation, conflict resolution, and pre-commit checks. GitX is built with safety in mind, avoiding force-pushes, protecting existing branches, and flagging files that may contain secrets or credentials. It follows the portable SKILL.md Agent Skills format and can be installed via npx, with the creator actively seeking feedback on whether its commit-grouping logic matches how developers would organize changes themselves.

Google shifts TPU management to Compute Engine as Cloud TPU API enters maintenance mode

Google has stopped active development of the Cloud TPU API, limiting it to bug fixes and security patches only, with no published sunset date. New TPU hardware generations, beginning with TPU7x (Ironwood), are exclusively supported through Compute Engine or Google Kubernetes Engine. A developer documented migrating a v6e-1 (Trillium) chip running the Gemma model under vLLM from the old queued-resources API to the new Compute Engine instances workflow. The core change involves replacing TPU-specific CLI flags and commands with Compute Engine equivalents, such as swapping accelerator-type for machine-type and using gcloud compute instances instead of gcloud compute tpus. Developers on v5p and v6e can migrate without special access, while TPU7x flex-start provisioning currently requires allowlist approval from Google's account team.
