Docker Compose on a Linux server should start on boot, stop cleanly on shutdown, and survive reboots without manual intervention.

Installing Docker on Ubuntu should be simple, but in practice several Docker-shaped options compete for the same command name, each with different packaging, upgrade behavior, and security implications.

APT failures are common on long-lived Ubuntu machines, and they usually appear after a release upgrade, a third-party repository change, a removed PPA, a manually installed .deb, or an interrupted package installation.

A 70B model generates one token per forward pass, and each pass reloads weights from VRAM, computes attention across the context, and synchronizes memory. Between tokens, the GPU sits idle while it waits for sequential dependencies to resolve.

Single-agent AI systems peaked in 2025 — you gave one LLM a prompt, some tools, and a goal, and it did reasonably well on bounded tasks.

Two writes that should succeed together will eventually fail separately. Your order service saves the order to the database, then publishes an order.created event to a message broker.

Go’s context.Context is simple enough to use badly — and that is the problem.

Spec-Driven Development is one of those ideas that software engineers have reached for before and then set aside when the effort stopped paying.

Spec-Driven Development entered 2026 as the serious developer’s answer to vibe coding drift.

Decision records are the missing memory layer in AI-assisted software development. They capture not just what was built, but why — and that distinction becomes critical when AI tools are writing your code.

Go error handling is easy to complain about. Every Go developer has written this code hundreds of times:

Testing concurrent Go code has always required a bit of discipline. Goroutines are cheap, channels are simple, and context cancellation is idiomatic — background workers and timers are everywhere in real Go services.

Google’s Agent2Agent protocol, usually shortened to A2A, had a strange first year.

Polling agents are one of the least glamorous parts of AI assistant architecture, but they are also one of the most useful.

The A2A Protocol, short for Agent2Agent Protocol, is an open standard for communication between independent AI agent systems.

AI agent architecture is starting to split into two layers.
