Developer tools news — AI coding assistants, IDEs, CLI tools, APIs, and productivity tools for software engineers. GitHub Copilot, Cursor, and more.
The article announces that union types, a long-requested feature common in functional programming languages, are finally being introduced in C# 15 as part of the .NET 11 preview. It explains how the new `union` keyword a…
User-space security agents are structurally flawed because they share the same privilege level as the processes they monitor, allowing attackers with root access to simply kill the agent or erase logs. It explains that e…
After 1,000 hours of using AI coding agents across various projects, the author found that success depends not on the specific AI model or tool, but on how work is structured before being handed off. The key insight is t…
Chrome DevTools for agents 1.0, released on May 19, 2026, provides AI coding tools with direct visibility into live browser environments to verify, debug, and optimize code in real time. The stable release includes a Mod…
The article announces new "Declarative Partial Updates" APIs being developed by the Chrome team, available for testing in Chrome 148. These APIs introduce out-of-order streaming using `` elements and processing…
At Google I/O 2026, Google unveiled a vision for the "agentic web," introducing 15 updates to Chrome focused on empowering AI agents, enhancing web UI and performance, and integrating Gemini as a proactive browser assist…
The article introduces the new experimental HTML-in-Canvas API, now available in an origin trial, which allows developers to render DOM content directly into a 2D canvas or WebGL/WebGPU texture while maintaining interact…
Maturity ladder for AI agent instruction systems, categorizing configurations from L0 (System) to L7 (Adaptive) based on the communication channel each level uses. The key distinction is between the "soft channel" (L0-L5…
Armorer v0.1.19, an experimental local control plane designed to manage the operational challenges of running AI agents, such as configuration drift and failed runs. Unlike an agent framework, Armorer functions as a loca…
Using GitHub Copilot CLI as a triage tool to manage open-source contributions across over 40 repositories. The workflow relies on four key prompts: explaining a repo's architecture, locating specific files, explaining fu…
Tool-using research agent built for the Gemma 4 DEV Challenge, which runs locally on the Gemma 4 e2b model via Ollama using roughly 200 lines of Node.js code. The agent accepts a question, selects between two tools to re…
The author successfully ran Google's new Gemma 4 open models (2B and 4B parameters) on a laptop using Ollama during Google I/O 2026 week. To make the small 2B model function as a useful research agent, they built a five-…
To measure and monitor prompt cache hit ratios in Hermes Agent to reduce costs, as cache-breaking significantly increases expenses. It introduces a Python library called cachebench that wraps model client calls to track …
Fully local AI system using Llama 3 and LangChain to enable natural language querying of an internal SQLite database, eliminating any data being sent to third-party servers and avoiding legal compliance issues. The syste…
A system streaming AI model outputs in realtime experienced severe latency spikes, message loss, and connection storms after scaling to 100,000 WebSocket connections, revealing the inadequacy of a simple Redis pub/sub la…
Manual testing remains a vital component of software quality assurance despite the rise of automation and AI, as it offers unique strengths like empathy for user experience and flexibility. Key manual testing techniques …
According to a 2024 McKinsey report, organizations are shifting from using AI as a productivity tool to embedding agentic systems—autonomous orchestrators—into core business processes, marking a fundamental architectural…
Slow single-image diffusion model inference is primarily caused by kernel launch overhead and attention memory traffic, not by a lack of computational power. It recommends using `torch.compile` with `mode="reduce-overhea…
Hermes Agent is an open-source agent framework developed by Nous Research that can run on various infrastructures, from a low-cost VPS to a GPU cluster. Unlike most agent frameworks, it is self-improving, learning from e…
Relying on autonomous OSINT (Open Source Intelligence) AI agents, which are gaining popularity in Japanese security communities, leads to "skill atrophy" among human analysts. It describes a "Skeleton Implementation" pro…
