The Ultimate Claude Code Guide to ship like Anthropic engineers

AI will write 90% of code by the end of 2026, and only 10% of developers will stay relevant.

The engineers in that 10% aren't smarter. They just know how to use AI.

We put together the exact playbook Anthropic engineers use to make sure you're in the top 10%.

  • The Code newsletter — learn the latest AI tools, tips, and skills to code faster with AI in 5 minutes a day


Quote of the Week

“Software engineering is what happens to programming when you add time and other programmers.” - Russ Cox


News

Vercel is offering up to $1M in total bounties for researchers who can break out of Vercel Sandbox, including escaping its Firecracker microVM boundary or bypassing host-side network controls. The post also explains how Vercel isolates untrusted agent code using microVMs, containers, and network policy enforcement.

Modular has fully open-sourced the Mojo programming language, including its compiler and tooling, under the Apache 2.0 license with LLVM exceptions. Developers can now build Mojo from source, modify the compiler and standard library, run the test suite, and explore how the language targets GPUs, AI accelerators, and other advanced compute.


Reading List

This is a deep technical piece on the challenges of hosting Git at scale, covering packfiles, distributed filesystems, consistency, replication, three-phase commit, and GitHub's Spokes architecture. It then explains Cursor's new Continuity architecture, which uses an S3-backed write-ahead log and local NVMe repositories to scale from huge monorepos to millions of small agent-created repositories.

A detailed retro-programming story about building a C compiler, assembler, text editor, and web browser for a homebrew Am29000 computer with just 512 KB of RAM. It covers compiler bootstrapping, register allocation, custom operating-system tooling, networking, and eventually bringing a 1999 browser back online 27 years later.

This article explores new techniques for calculating the day of the week using multiplication, shifts, and bit manipulation instead of conventional modulus operations. The resulting algorithms outperform existing approaches across x86 and ARM processors, with techniques that also generalize to other fast modulus calculations.

DuckDB v2.0 is coming this fall. In this post, we preview its headline features: DuckDB as a server, triggers, the VARIANT type, asynchronous I/O, a new SQL parser, a new storage format, and much more.

Beeswax improves eBPF performance by restructuring programs into multiple stages and using multi-phase data structures to hide cache-miss latency. Applied to production systems like Katran and BMC, it improves throughput by up to 99% with relatively small changes to existing programs.

This post is a deep dive into how an RTX 4090 handles a GPU memory load, tracing data through the L1 cache, address translation, L2 cache, memory controller, and GDDR6X DRAM. It uses hardware experiments and reverse engineering to uncover undocumented GPU behavior and measure memory latencies along the way.

An experiment in using Codex to autonomously optimize a GPU QR decomposition kernel, ultimately achieving a 232x speedup over the baseline. The author shares how tight feedback loops, profiling, human steering, and maintaining multiple competing ideas helped the agent continually improve performance.

A year of fighting scrapers on my 1.5 million-page website. What I tried, how I failed, and what's working now.

Learn how probes work interactively on simulated Kubernetes clusters running in your browser.

Secure Boot can still be compromised even when the underlying cryptography is sound, due to weaknesses in validation, image parsing, rollback protection, and boot-stage enforcement. The article examines hardware roots of trust, Qualcomm boot chains, Android Verified Boot, UEFI, measured boot, and attestation to show where implementation flaws can allow unauthorized code to run.


Watch, Listen

Philip O’Toole, creator of rqlite, shares how he uses testing as a core design strategy and AI agents as technical research assistants. He explains how AI helped cut his typical 18-month release cycle to six months and discusses the future of managing agent swarms for critical infrastructure.

A tour of how modern TLS has evolved, from simpler TLS 1.3 cipher suites and mandatory forward secrecy to automated certificates through Let’s Encrypt. It also covers shrinking certificate lifetimes, why these changes happened, and what can break if older TLS practices are not updated.

Learn how to design and build a production-ready, multi-agent AI system that automates pull request reviews with senior-level engineering judgment. This comprehensive tutorial covers everything from fault-tolerant system architecture and database modeling to utilizing the Genesis kit for reliable, AI-native development.


Interesting Projects, Tools and Libraries

Textlog is an open-source, minimalist social network for sharing 280-character notes, following people and hashtags, and joining conversations. It focuses on words and simple interactions without engagement tricks or pressure to build an audience.

Starboard is an open-source macOS terminal that lives permanently beside the Dock, staying visible across desktops and full-screen apps without stealing focus. It provides a persistent shell with command history and state, eliminating the need to summon, resize, or switch back to a terminal window.

Wyzer is a statically typed, compiled, resource-oriented programming language with integrated distributed safety via choreographic programming and a perceus memory model.

A Frontier Mathematical Coding Agent.

A deep-research agent with an enforced budget, verified quotes, and a privacy boundary for local data.

An open-source typeface that protects written work by poisoning unauthorized AI training datasets.

Switchyard lets LLM applications route traffic across models and providers while preserving native OpenAI and Anthropic API compatibility - enabling flexible model selection, benchmarking, and cost/performance optimization.

An interpreter for the Wolfram Language powered by Rust.
