Why is Google still serving dodgy ads?AI is really good at detecting deceptive adverts - why isn't Google using it?
The author documents a deceptive Google ad that mimicked an iOS system dialog, violating multiple Google ad policies, and argues that Google's own AI could trivially detect and reject such ads—raising the question of why it does not enforce its own rules.

LLM Classification Is Feature Engineering
Taylor Pospisil argues LLMs work better as feature generators than as end-to-end classifiers, covering calibration, thresholding, cost, and how to treat model outputs as engineered features.

A 40ms Go GC pause caused by swap
Running swap in production to absorb memory spikes, the author found that Go's garbage collector reads off-heap metadata during a stop-the-world pause, and when that metadata is swapped out the pause jumps from a median of about 51 microseconds to 40ms. Includes eBPF measurements and a note on Go 1.26's Green Tea GC.

Alexandre Lamure walks through first-principles differences when porting a small OpenGL engine to Vulkan—bindless resources, explicit synchronization, and modern Vulkan 1.3 patterns—with pointers to nebula and further reading.

The mystery animal on an ancient god’s head
Signore Galilei investigates the strange animal depicted atop an ancient deity’s head—tracing iconography, competing identifications, and what the motif may have meant to its makers.

A heap overflow and SSO misconfiguration to compromise OpenAI internal repositories
9 min · 2,047 words
Paul Graham argues that the most productive question a founder can ask is not how to make more money but how to make the company more powerful. The essay works through several structural moves—owning the customer relationship, enabling app-store-like extensibility, introducing network effects, going full-stack, getting customers earlier, and getting data earlier—that each tend to produce power disproportionate to the effort they require.

Principles for fast Tokio applications
A practical guide to building low-latency, high-throughput applications on the Tokio async runtime, written from experience debugging real production systems. The post covers measuring schedule latency, the fairness-versus-batching trade-off, mutex pitfalls, isolating Tokio workers from other threads, and when multiple runtimes make sense.

Systems engineer Bryan Cantrill uses a youthful prank, falsely alarming a computer lab about a virus outbreak, as a frame for criticising AI-safety researchers who publicly claim more than a ten percent chance that AI will kill all humans. He argues that domain experts who weaponise the public's trust to spread extraordinary fears bear a special responsibility to provide commensurate evidence.

Mathematician Daniel Litt argues that AI systems now capable of resolving major open problems need not mean the end of meaningful human mathematics, but they do require institutions to sharply distinguish mathematical understanding from mathematical text production. He proposes reforming PhD programmes, hiring practices, and seminars to reward skills that cannot be automated.

I made a build profiler to understand Bun's compile times
Lalit Maganti built buildprof, an open-source Linux tool that records every process spawned during a build and renders them on a shared timeline. He used it to investigate the 5x speed difference between Bun's Zig and Rust builds, tracing the bottleneck to Full LTO in the linker and a downloaded WebKit library that amplified it.

The author designs a compact binary encoding scheme for national flags using a layered model and Huffman coding. Most flags can be represented in 55–76 bits by exploiting the statistical regularity of flag elements — stripes, stars, crescents, common aspect ratios — while allowing longer codes for complex outliers like Qatar.

Ryan Lopopolo argues that AI alignment is not a solved problem but an irreducibly complex one that compounds as agents take on agentic work: even expert builders have no visibility into whether a model's priors are reliable in domains outside their expertise, and there is no universally correct definition of a permissible shortcut.

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.

Global Shortage Has Led To Motor Oil Rationing At Costco
Costco has raised the price of its Kirkland Signature 10-quart synthetic motor oil from the mid-$30s to $57.99 and limited purchases to two units per seven days. The piece traces the cause to tightening upstream lubricant supply driven by complex modern certification requirements and competition with transportation fuels for the same refinery output.
