Gemini 4 Argon launched on 30 September 2026 — but only for vetted cyber defenders. What platform teams on Google Cloud should change now: the 1M-token output budget, Argon vs Gemini 3.8 Flash routing, agent guardrails, and the deadlines that land before Argon does.
Agent Skills are folders with a SKILL.md file that AI agents load on demand. How the open standard works, what each frontmatter field does, where Claude Code, Copilot and Codex look for skills, how skills differ from MCP, AGENTS.md and subagents, and why every skill you install is part of your software supply chain.
WebMCP explained: how the new browser API lets AI agents call a website's JavaScript as MCP-style tools, how Chrome 149 implements registration, discovery and execution, how WebMCP differs from MCP servers, and what I learned shipping seven WebMCP tools to production.
Claude Sonnet 5.5 vs Opus 5.5 compared on benchmarks, list price and real cost per agent turn, why the savings disappear at max effort, the five breaking changes from Sonnet 5, and why a Sonnet-Opus router silently drops the model's reasoning on the way back down.
All six Claude Code permission modes compared — Manual, acceptEdits, plan, auto, dontAsk and bypassPermissions — what each one lets the agent do, why auto mode replaced plan mode as the default, what the auto-mode classifier blocks and allows, and a settings.json that holds up.
On 23 September 2026, an independent AI-safety lab published forensic evidence that autonomous AI agents hacked into three public data services, including an Australian government site, while doing nothing more than trying to answer an ordinary question. Hours later, OpenAI and Australia's Prime Minister both confirmed it. Here is what the data actually shows, and what it means for anyone running a public API.
AWS, Google Cloud and Azure all say free, but they mean three different things: a credit that expires, a monthly allowance that never does, and a clock you did not notice starting. A side-by-side of the sign-up credits, the always-free limits, what happens on the day the credit ends, and the traps that turn a free account into an invoice.
SQLite works remarkably well inside a Go service when the connection pool respects its locking model. This guide compares current drivers, measures their actual cost, and builds a production setup around WAL, bounded pools, short transactions, checkpoints, backups and observable failure modes.
Kubernetes 1.35, 1.36 and 1.37 changed far more than their release-note headlines suggest. A production-focused map of security defaults, autoscaling, AI scheduling, storage, control-plane resilience, upgrade traps, and the still-moving 1.38 release.
Jev does not try to out-chat GPT-5 or Claude. It removes text generation from a narrower job: making typed, probabilistic decisions inside software. That can be a major architectural advantage — if your task really is a decision.
Swap jest for vi and most of a Jest suite runs on Vitest untouched. The problems are not the calls that throw — they are the ones that keep passing while meaning something different. A migration guide organised by how each difference fails.
matplotlib, seaborn, plotly, bokeh and altair all draw a bar chart. What separates them is where the chart is rendered and where your data ends up when it is. A practical guide to picking one, with the specific constraint each library carries.
Everyone estimates the compute and gets surprised by the network. A costed comparison of the four meters that actually move a cloud bill — internet egress, NAT, cross-zone traffic and the Kubernetes control plane — priced from the AWS, Google Cloud and Azure documentation, with an honest ranking of what to fix first.
ollama run llama3 gets a model answering in thirty seconds. Getting that same model to serve 200 concurrent users without falling over is a completely different engineering problem — and vLLM and Ollama solve it in opposite ways.
A password is a secret both sides have to keep. A passkey is a key pair only one side ever holds. This is what that actually means at the protocol level — with three diagrams for registration, login and the sync fabrics — plus who ships passkeys today and how to roll them out without breaking account recovery.
