The Search API and Fetch API provide access to live web content, allowing agents and RAG applications to search for web pages using a query. Both APIs use the same bearer authentication as the DeepSeek API and return raw JSON results.
The author explains parser combinators as a way to parse structured data from unstructured text, using functions that combine and transform parsers. They demonstrate three fundamental combinator functions: pSeq (sequence), pMap (map), and pRepeat (repeat).
Sphinx is a Git hook that asks questions about code before shipping, built for minimal tokens and compatible with various coding agents. It helps reviewers understand changes by asking questions when things go wrong or succeed.
The documentary "You Can See Everything" masterfully manipulates viewers' emotions, forcing them to confront how much of their opinion of Elizabeth Holmes comes from the story's narrative rather than facts. The film expertly uses camera angles, editing, and framing to create a visceral experience that challenges viewers' perceptions and biases.
Scientists have restored bleached coral in a lab by touching it to healthy fragments, giving hope for reversing widespread decline. This process allows the coral to regain its color and nutrients through symbiotic algae transfer.
Teal is a statically-typed Lua dialect with type annotations, aiming to fill the niche of TypeScript in JavaScript. It's implemented as a compiler and has various tools and integrations for building projects.
Meta revised its terms of service to remove "train" from allowed uses of scraped content, limiting it to advertising and business products. Legal experts argue the revised terms still permit broad scraping and could be used to train AI models.
Lean's AI agents have improved the proof checker kernel, adding new kernels and tools for rechecking Lean developments. The latest version includes four verified kernels: nanoda, lean4lean, con-leche, and con-ron.

DeepSeek-V4.1-Flash is a minor update with improvements in reasoning, coding, and visual benchmarks. It reduces task execution time and output length for faster completion at lower cost.
A dam removal movement in the US has led to over 2,500 miles of waterways being reconnected since 2024, with many more dams expected to be removed. The effort aims to restore habitats for fish species such as salmon and alewives that were previously blocked by dams.
Pele is a library that renders Mermaid diagrams to SVG with customizable CSS variables. It's used to create flowcharts and other diagrams, rendering them as SVG elements in the browser.
Anthropic, a company at the forefront of AI adoption, has seen its work and employment structure change significantly as hours worked by AI agents have expanded rapidly. The company has hired less for junior technical positions while productivity for both engineers and non-technical employees has increased sharply when they adopted coding agents.
Furigana is a Japanese font that shows readings on the text itself, supporting custom fonts and working everywhere. It uses ligatures to adopt pronunciation of words and can be installed as a bookmarklet or userscript for easy use.
The author attempted to make chicken breast transparent by soaking it in a tartrazine solution, similar to a paper that achieved optical transparency in live animals. The goal is to change the refractive index of water inside the tissue to match its embedded media, making it more transparent and allowing for better imaging.
France and the UK are considering age restrictions on social media, but these bans may be easily circumvented by teens. Instead of focusing on enforcement, policymakers should address the root causes of online risks by limiting data collection and providing user-controlled tools to limit access to undesirable content.
A southern ground hornbill at Artis Zoo in Amsterdam received 3D-printed prosthetic beaks to replace broken parts after an injury. The bird successfully used its new beak within hours of the surgery, showing promising results for this innovative treatment.
The C64-hw-sim program simulates the Commodore 64 motherboard at a pin-by-pin level, allowing users to test and diagnose faults without damaging the hardware. It runs on macOS and Linux with OpenGL graphics library and interface library nuklear.
lpviz is an interactive web app for visualizing linear programming solvers. Draw your constraints and objective, and see how methods like IPM, PDHG, Simplex, the Ellipsoid method, and Central Path solve your problem.
The author discusses how large language models can recall obscure facts from every corner of the world, and how this ability is similar to a memory store that holds key-value pairs. The author then develops an intuitive way to look at linear maps, MLPs, and self-attention as different kinds of memory stores.
The author has extended the C Preprocessor with custom macros to improve its usability, including a print function and macro expansion tracking. These extensions allow for more readable and efficient use of the preprocessor.
Rep. Ritchie Torres introduces the Power To The Players Act to protect consumers by giving them ownership of video games rather than licenses, and requiring publishers to provide offline modes before shutting down servers. This legislation aims to curb anti-consumer business practices such as revocable licenses and aggressive monetization schemes in the gaming industry.
It’s time for Marc’s Amateur Statistics Corner! Today: why I pay a lot of attention to tail latency when optimizing cost. I’ve written before on the importance of tail latency for customer experience (e.g. in 2026, 2021, and 2021, and 2017). Today, I want to talk about tail latency from the perspective of cost and capacity. Here’s a question: how much does each of my latency percentiles ...
p peas · h headphones · space pause · rings at 5, 10, 20 and 40 m A small flock of mallards going about their day: three hens, two drakes and two broods of ducklings. No recordings. Every quack is synthesized as it happens and heard from where you stand on the bank. I'm wearing headphones
The author implemented a brute-force search to find an optimal formula for finding the lowest set bit in a float value, and after 4 minutes of computation, they found one that works. The formula is cleverly rewritten to reuse subexpressions, saving one operation.
The US is exporting more gold than usual, with most going to Switzerland and Hong Kong, possibly due to foreign governments' concerns about the dollar's value. This surge in exports may be linked to China's growing gold reserves and its efforts to reduce reliance on the US dollar.
Vacuula is an all-in-one solution to repair and control broken Neato Robot vacuums. The project supports various models, including Gen4 robots in "rainbow mode" that won't start.
The user's Codex Desktop app is experiencing unbounded local disk growth due to continuous Crashpad dump generation, despite remaining functional. The issue appears to be a background process continuously generating pending dumps without cleanup or rotation.
Estimates for a short prompt on a single device. Measured numbers come from community benchmarks (r/LocalLLaMA, localscore.ai and more); others are derived from similar setups or projected from specs. Open source on GitHub.
esp32sim is an emulator that runs ESP32 SoCs, including the S3 and C6 models, with unmodified application images. It boots real mask ROMs and 2nd-stage bootloaders without patched firmware or stubs.
