Terrible Software's Brain Sandwich is a framework for using AI in engineering without losing your own thinking. First, your brain reads and clarifies the problem to form a rough direction. Then you bring in AI to implement. Finally your brain returns to review, assess complexity, and refine the PR description so others can review. The aim is to avoid AI biasing you toward the wrong problem while keeping your thinking engaged and ensuring work is explainable.
Neuroscientist Jared Cooney Horvath says Gen Z is the first generation to score lower on standardized tests than the previous one, with declines in attention, memory, literacy, numeracy, executive function, and IQ. He links this to extensive screen time and classroom tech that favors skimming over deep learning. The pattern appears in about 80 countries after digital tech became widespread. Horvath urged less screen exposure in schools and more rigorous, friction-rich learning to rebuild cognitive skills.
Simon Willison experiments with Chirp Pong: a two-player Pong-like game played on two nearby phones with static HTML, where the game state is transmitted via chirps heard by the microphones and decoded by the Web Audio API. Adds graphical and gameplay twists to make it more engaging than Pong.
μRepRap - The RepRapMicron Project describes a RepRap-like micron-scale fabrication system enabling printing and manipulation at micrometer resolution. Building on The OpenFlexure Project, it aims to create a macro-to-micron scale CNC with a 3-axis positioning system, deposition head, and Z-touch probe. Hardware centers on PIKA V0.02 and MAUS variants, driven by Arduino GRBL with G-code. Capillary UV resin deposition and optical probing enable sub-15 μm droplets and about 1 μm repeatable positioning within an approximately 8 mm cubic volume. The goal is an affordable, scalable micron fabrication platform for future devices.
Advocates setting a user-agent and complying with the robots policy; references policy documentation and Phabricator task T400119.
Open-source Micro-Manipulator: a low-cost, open-source motorized XYZ motion platform achieving sub-micron precision for optical alignment, probing, and microscopy. It uses parallel kinematic structure with miniature ball joints, off-the-shelf steppers, and a 30 kHz closed-loop controller. Magnetic gearing boosts low-cost encoder resolution up to ~50 nm steps. Controlled via simple USB-G-Code interface; firmware features look-ahead motion planning and 6DOF-pose interpolation. Hardware version 4.0 fixes self-collision during homing, linkage constraints, and ball-joint friction; FreeCAD CAD models and STL files provided; includes a GUI, Python API, and setup guides to build, calibrate, and operate.

MIT Technology Review argues that age gates and bans for minors on social media are largely ineffective and counterproductive. In Australia, four in five under-16s bypassed a 2024 ban, using tactics like a sibling’s ID or fake facial features. Such bans curb access to information and healthy development, but often push youths to unmonitored, riskier spaces and raise privacy concerns from data collection and VPN restrictions. The authors advocate smarter policies: limit data collection, give families flexible, user-friendly control tools, and provide targeted protections rather than blanket, hard-to-enforce bans.
Marc Brooker explains that tail latency matters for cost and capacity. He demonstrates how to compute the empirical Lorenz curve to measure how much latency beyond a given percentile contributes to the mean (and thus to concurrency via Little's law). He shows that tails often dominate cost—e.g., p50 can account for ~99% of mean latency; p99 ~50%—so optimizing the tail can reduce concurrency and capacity needs, though measurements have interpolation/extrapolation caveats.
TEEs promise isolation but are fragile in practice. The article surveys attacks across: bugs in enclave code that leak data; remote attestation forgery affecting SGX/SEV; and liveness/DoS issues like revocations or slow recoveries. It also highlights physical-interposition attacks (DDR4/5, etc.) that let attackers impersonate genuine hardware. A defender’s dilemma: secure attestation requires PKI pinning, which is brittle. While principled designs (e.g., Sanctum) exist, they trade performance or functionality. Conclusion: don’t place valuable secrets in TEEs unless your threat model includes powerful physical access and you accept the risks.
Anthropic’s use of Claude and AI agents is reshaping work: by Aug 2026 agent hours outnumber human hours six to one, and output per employee rises as teams adopt AI, with human attention the bottleneck. Junior technical hiring shrank (27% to 9%), while overall technical headcount share fell; non-technical coding also rises; meta-work grows as employees build tools and monitor pipelines. Hiring now emphasizes autonomy and judgment over domain expertise. The company runs an early warning system and redeploys staff internally, while stock ownership aligns worker incentives with success. These patterns offer lessons for AI-driven labor reallocation.
Parser Combinators demonstrates building a small, composable parsing library in TypeScript. It defines a Parser<T> as (input: string) => [T, string], introduces partial parsers like pInteger, pHello, pIgnoreWhitespace, and shows chaining with pSeq, pMap, and pRepeat to turn unstructured text into structured data. It argues parser combinators are cleaner than regex or tree-sitter for many tasks, enabling readable, maintainable parsing. Includes a real-world example parsing ping output into typed data (PingResult, PingHeader, IcmpPacket, PingStatistics) and explains the unfold/fold analogy.

Roots of unity are complex numbers z with z^n = 1. The nth roots are z_k = e^{2π i k/n}, k = 0,...,n−1, evenly on the unit circle. Real roots are only 1 and −1; complex roots rotate under powers. Conjugates z_k^{-1} = z_{n−k} are also nth roots. They form a regular n-gon on the circle. μ_n under multiplication is a cyclic abelian group; w = e^{2π i/n} is a generator, and w^k generates iff gcd(k,n)=1 (primitive roots). Sum of all roots is 0; sums ∑ w^{k i} vanish unless n|k. The vectors [1, w^j, w^{2j}, ..., w^{(n−1)j}] are orthogonal; the Fourier matrix V encodes the DFT.
DeepSeek provides two raw JSON APIs: Search to find web pages and Fetch to retrieve a page’s content in Markdown. Use base URL https://api.deepseek.com with Bearer authentication for /v1/tools/search and /v1/tools/fetch. Search accepts query (1–128 chars), count (1–50), need_content, and operators (site:, -site:, "..." phrases, lang:, after:, before:). Fetch requires a URL. Responses include titles, URLs, and either summaries and content for Search, or content for Fetch. Errors follow OpenAI-compatible formats; billing is $0.75 per 1,000 successful Search/Fetch; 5 QPS per API; read-only.
David Priver describes extending the C preprocessor beyond a text translator to a token-based tool, sharing handy macros to aid debugging and code generation. He introduces __print() and __where() for debugging macro expansions and macro definition locations. He demonstrates a linear-map macro __map(...) to apply a macro to a list of arguments without recursion, plus techniques to count arguments with NARG and NARG_ using C23 __VA_OPT__. He shows __VA_COUNT__ to obtain variadic arg counts for functions like sum. He argues these extensions boost power and readability, while noting the dark magic of preprocessing and promising more ideas.
Edge's cover story outlines a grim slide in the game industry: about 58,000 jobs lost 2022–2026, ballooning budgets, studio closures, and stagnant audience growth despite revenue. Diagnosed by Amir Satvat, layoffs are patchy and localized to Western hubs; Japan shows leaner teams and lower exec pay. The piece canvasses six proposals: emulate Japan’s lean staffing; build smaller, 20‑hour games; target low-end specs; shift toward ecosystem platforms and interoperability; rethink royalties/crediting; avoid IPOs to preserve long-term decision-making. It also notes limits of AI, co-development, and platform resets, and argues for broader systemic reform and worker protections.
