Eddie argues that Pandas forces data practitioners to adopt distributed compute infrastructure long before their data sizes justify it, and that DuckDB and Polars can fill the gap for workloads up to around 100 GB on a single machine. Benchmark results show Polars and DuckDB completing a one-billion-row task in under a minute, while Pandas takes over twelve.

A Search-and-Inference Database from Scratch in Pure Zig
Antfly recounts rewriting their Go retrieval engine in Zig while still early: first-principles design, caring about the model over embeddings, TigerBeetle-style simulation testing, and what they learned.

Resurrecting iChat Audio and Video Conferencing
Chris Jones explains how he got Apple iChat AV audio and video calls working again on Mac OS X Leopard and Snow Leopard: with old network captures and LLM help he reverse engineered the dead SNATMAP NAT-discovery service, wrote a small UDP replacement server, and now one /etc/hosts line points old Macs at his public instance or a self-hosted one.

I expected better from GoogleWhat we found in Artemis, and why open-source credit matters.
Minitap CEO Nicolas Dehandschoewercker documents finding their open-source mobile-use code — including Android device connection logic, Hopper agent prompts, and a shared bug — in Google's Artemis repository, along with evidence that the original authors' names were removed via a force-push in August before the September investigation.

Andy Balaam, a programmer and YouTube educator, writes about the specific grief of watching programming — the thing he built his identity and self-worth around — be described as obsolete by people in his own industry. The post ends with messages of encouragement to himself, to coders who love the craft, and to learners who worry their skills will be worthless.

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.

MotherDuck's Mehdi Ouazza benchmarks the DuckDB 2.0 alpha on a laptop and S3, covering async I/O read-ahead that makes S3 reads 2-3x faster with no query changes, faster recursive CTEs for deep hierarchies, shredded VARIANT columns that beat JSON parsing about sixfold, and smaller wins from the commit log.

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.

Introducing mapsnap: Automated Georeferencing for Historic Sanborn Insurance Maps
Dan Vanderkam introduces mapsnap, a program that automatically georeferences historic Sanborn fire insurance maps from the Library of Congress. He explains why these block-by-block maps are valuable, how mapsnap matches them to modern street data, where it fails, and his goal of georeferencing at least 90 percent of the collection, browsable at mapsnap.org.

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.
