Context management is an underrated habit
How you manage context in a Claude Code session has a direct effect on both your token bill and the quality of what you get back. Do it well and you spend less for better work. An efficient session gives Claude the context it needs to finish the job while removing context that has stopped being useful. That means starting with a lean setup, keeping investigations focused, and deliberately deciding when to continue, compact, or start again. Here are the context management techniques we use on the

Python 3.15 ships with a new profiler. It is called Tachyon, it lives in the standard library as the profiling.sampling module, and unlike cProfile it is a sampling profiler rather than a tracing one. I now have a set of hands-on workshops for it, which you can find at github.com/GrahamDumpleton/tachyon-workshops or on the workshops page of this site, and they have reached the point where I am happy for other people to do them. That said, they were not written for other people in the first place. They were written so I could learn Tachyon myself, and the reason I wanted...

Free the models: Harness design at the frontierWhy Replit Agent lets the core loop pick subagent tier, effort, and specialists—and beats rigid routers on cost/score
Replit's AI team argues model routers are always weaker than the models they choose for. Their harness lets GPT-6 Astra decide effort and delegation; on DeepSWE and Terminal-Bench, Replit Agent is Pareto-efficient versus Astra alone and a sidekick architecture.

You Said No MCP!Why Pi (pi.dev) brought MCP into the core after years of saying no
Earendil explains why Pi now ships MCP in core: MCP matured, Codemode/JavaScript sandbox composition made it useful, and embracing modern MCP helps shape better tool patterns for small harnesses.

Why I Stopped Defaulting to Next.js and Vercel
How AI coding agents made it practical for me to build and own a different stack with TanStack Start and Cloudflare. The first person who introduced me to Next.js was my friend Haythem Lazaar. We were at university, building Collo , a project management tool for remote teams.

Don't couple your Go code to GitHub
Iain Cambridge explains why Go import paths that hard-code github.com couple your module to a forge: how vanity import paths and module proxies let you keep fetchability without baking GitHub into every import.

Why Claude Opus 5.5 Still Won't Fix Your AI Agents
VooStack argues that swapping in a stronger LLM won’t fix unreliable agents: the real work is orchestration, observability, and API design—the engineering discipline required to ship agents that hold up.
