RAG fails on PDFs because a PDF stores glyph positions, not document structure. Tables flatten, reading order scrambles, and no error is ever raised.

After nine industrial protocol investigations, an OT researcher explains how smaller labs, packet captures, and sharper questions improved the work.

Every week, I want to highlight one website, tool, or project that made me stop scrolling and think: “Okay, that is actually a fun idea.” This week’s pick is Nychthemeron — an open-source social platform where posts, comments, and messages disappear after 24 hours. Yes, completely disappear. No endless archive of old opinions. No post from 2017 waiting patiently to ruin your afternoon. No carefully maintained feed of things you said when you were tired, overconfident, or had ju...

Connecting an AI agent to internal tools is the first time most teams confront a security boundary that is not enforced by code alone. Traditional programs take instructions from developers and data from users; an LLM-driven agent takes instructions from both , and it cannot reliably tell them apart. A field value, an issue comment, a web page, or a tool description can all contain text that changes what the model does next. The Model Context Protocol does not solve this; it makes the boundary ...

TL;DR: A scheduled Node.js job needs two signals. Emit a structured completion or error event so operators can search what happened, and send a heartbeat to an independent monitor so it can notice when nothing happened. Logs alone can explain a crash, but they cannot prove that a scheduler ever launched the job. For a nightly media pipeline, I would keep those signals behind a tiny application-owned interface and deploy the monitor change before the job change. That makes rollback boring: the...

Cross-Modal Knowledge Distillation for bio-inspired soft robotics maintenance in hybrid quantum-classical pipelines Introduction: A Detour That Changed How I Think About Robot Maintenance Six months ago, I was deep into a rabbit hole studying knowledge distillation for a completely different reason — I wanted to compress a large vision transformer into something that could run on a microcontroller for a home automation project. Somewhere around 2 AM, while reading a paper on cro...

The best small-SaaS observability stack is the smallest system that can distinguish customer-visible notification delivery failure from an unhealthy process, while retaining enough logs, metrics, and error detail to explain the difference across Europe and the US. TL;DR: probe the public path from outside each serving region, measure delivery outcomes inside the application, correlate both with structured events, and page only on sustained SLO risk. A green /health response is useful evidence,...

A single MCP server in front of one service is a solved problem: generate tools from the OpenAPI spec, run it over stdio or HTTP, done. At company scale the problem changes shape. A midsize platform team has forty services, each with its own spec, its own auth, its own staging and production hosts. Let every team publish an MCP endpoint and you quickly get: Agents configured against dozens of URLs, each with its own OAuth consent. Tool catalogs in the hundreds, past the limit most clients...

A customer-support SaaS has a harder constraint than evaluating a feature flag quickly: after a customer reports a missing reply, an incorrect queue assignment, or a conversation shown to the wrong agent group, the team needs enough durable evidence to reconstruct which configuration the request actually received. That constraint changes both the hosting choice and the pricing comparison. TL;DR: choose self-hosted or managed feature flags by testing the complete evidence path, not by compar...

"Transparency is not an option, but accountability to the colony's well-being will guide every action." Happy Saturday, everyone! This one started as my entry for a Kaggle AI benchmark challenge, but it didn't fit the requirements well, so here's the full experiment. A language model running on my desktop GPU wrote that before I'd shown it a single dilemma. I had asked it one question: what principles will guide you? I thought I had my headline: an AI that says outright it won't be ...

The gap between a demo agent and a reliable one is usually not model intelligence; it is output discipline. In a demo, the model calls get_weather({"city": "SF"}) and looks magical. In production it calls refund_payment({"payment_id": 7712, "amount": "49.00", "currency": "usd", "reason": "user asked nicely"}) — integer where you expect a string, string where you expect cents, an undeclared reason, and an extra field your handler silently ignores. Every one of those mismatches is a bug report...

A space data center sounds like it solves cooling for free: deep space sits at about −270 °C. Google's own engineers say the opposite. In the post announcing Project Suncatcher's first launch , Google calls cooling orbital data centers "a crucial research challenge", and according to Ars Technica its first test satellite can run its TPUs for only about 15 minutes before it has to stop and let the radiators catch up. If you care where AI compute gets built, and who pays for the power, this is th...

Suppressing the email when Jira Automation adds a comment (and why sendNotifications does nothing) Key takeaways sendNotifications is not a parameter of the automation Comment action, so nothing reads it. Your export proves the key is stored; your inbox proves it is not used. The Jira comment REST endpoint ignores unknown keys silently. I posted sendNotifications, notifyUsers and totallyMadeUpKey12345 to it and all three returned 201. notifyUsers is real — on Edit issue, o...

Dynamically-typed object-oriented languages please programmers, but their lack of static type information penalizes performance. Our new implementation techniques extract static type information from declaration-free programs. Our system compiles several copies of a given procedure, each customized for one receiver type, so that the type of the receiver is bound at compile time. The compiler predicts types that are statically unknown but likely, and inserts run-time type tests to verify its pred...

Huge open source projects have been successful by building upon dozens to hundreds of small libraries that encapsulate functionality and complexity. AI coding uses these libraries to quickly build applications. With the latest round of model releases I am seeing that AI can now generate the functionality of almost any library in-line as it generates the application. When building took a long time, breaking things down into well defined modules, shipping incrementally, and reusing code, were esse...
