Why Your Linux Kernel Starts With 'MZ' (Yes, the DOS/PE One)
A deep dive into why the Linux kernel image begins with the DOS/PE 'MZ' header—boot compatibility history, EFI stubs, and what the legacy magic bytes still do on modern systems.

Guest Post: Rust Is Tier-1 Language at Microsoft
Victor Ciura from Microsoft DevDiv announces that Rust has achieved Tier-1 language status at Microsoft, meaning it now has a fully paved path from local development to production. The post introduces rustc_codegen_utc, a new Rust code-generation backend that connects the Rust compiler to Microsoft's native MSVC toolchain.

Native is now the future of mobile at ShopifyCoding agents changed what it costs to build mobile apps twice. Here's why Shopify is moving from React Native back to Swift and Kotlin.
Shopify is abandoning React Native in favour of native Swift and Kotlin after determining that AI coding agents have erased the cross-platform code-reuse advantage. The post explains how a 2020 bet on React Native succeeded initially but became harder to justify once LLM-powered agents can translate, test, and review code across platforms cheaply.

Putting the trace before the loopAn observability-first approach for building an AI agent, and what it bought me.
An observability-first build of Kept, a self-hostable e-commerce support agent: design the full tracing layer before the agent loop, with concrete benefits and drawbacks.

How my e-reader lost its stripes
Bryan O'Sullivan bought a cheap Xteink X3 e-reader, installed open-source CrossPoint firmware, and noticed vertical stripes in greyscale images that were absent from the source bitmaps. Working with an AI coding agent, he traced the bug to how the firmware's greyscale nudge waveform interacts with the e-ink panel's gate driver timing, and submitted a patch that eliminated the stripes.

The part of Navier-Stokes no one is talking about
John D. Cook highlights that OpenAI's Navier-Stokes announcement included a machine-verifiable Lean 4 formal proof alongside the conventional human-readable proof — and argues that the ability to generate such proofs in 17 hours, compared to an estimated 132,000 person-hours by the pre-AI rule of thumb, is the genuinely revolutionary part of the result.

How I advertise malicious software on Google Ads
A developer promoting RACE, a macOS terminal multiplexer written in Rust, had their Google Ads account suspended for "Malicious software" despite the app being notarized and the site having no attack surface. Three appeals were rejected with generic automated responses, and the account was eventually reinstated only after the story gained traction on Hacker News — with no explanation ever provided.

Cohere's North Mini Code Megakernel Serving Engine
Today, Cohere presents a serving engine for North Mini Code built around a decode megakernel: BF16 on a single H100, 1.25× - 1.41× faster than vLLM end-to-end. Explore the code behind the serving engine on GitHub. Most LLM serving stacks still treat each forward pass as a sequence of kernels: launch QKV, wait; launch attention, wait; launch the MoE, wait. Each launch is fine on its own. The problem is the waiting in between. At small batch sizes, the GPU spends a surprising fraction of every decode step waiting rather than computing.

Prompted by reading Sarah Wynn-Williams's account of Facebook's internal culture, this personal essay traces a growing disillusionment with the internet as a whole — not just social media, but the pervasive requirement to maintain accounts, apps, subscriptions, and authentication layers just to accomplish basic daily tasks.

vLLM x AgentX: Optimizing for Real-World Agentic Serving
**TL;DR:** Agentic workloads are becoming a major source of vLLM traffic. Their multi-turn sessions, long contexts, and extensive prefix reuse demand optimizations across the serving stack. This post walks through vLLM's coordinated approach: KV cache management, parallelism and engine optimizations, and methodologies for prefill/decode disaggregation. Measured on AgentX, SemiAnalysis's public agentic benchmark, vLLM achieves up to 130K total tokens per GPU-second on DeepSeek V4 Pro, and an…

Understanding the Recent DDoS Attack Against Read the Docs
Read the Docs describes a ten-day DDoS attack in June 2026 that peaked at 5.5 million requests per minute, roughly 100 times normal traffic. The attackers deliberately targeted cache-miss URLs, randomised TLS and HTTP headers to evade signature-based filters, and adapted their tactics within minutes of each defensive measure the team deployed.

On the Navier–Stokes Millennium Prize Problem
Simon Willison documents OpenAI's claim to have resolved the Navier-Stokes Millennium Prize Problem using an internal model in under four days, and the ethical controversy that followed. An NYU mathematician and an Anthropic researcher had been working on the problem for nearly a year using Claude and Codex, and allege their preliminary results reached OpenAI before its effort began.

Law professor Eric Goldman analyses a Delaware court's preliminary injunction ruling in X Corp. v. Project Bluebird, finding that X has likely abandoned the TWEET trademark and the bird logo through non-use and public repudiation, while its ongoing 'formerly known as Twitter' references in app store listings may be enough to preserve the TWITTER mark for now.
