Amazon Web Services logged attempts to leverage the internet-melting PHP2Shell bugs four days ago. They’re now being “broadly exploited” across the internet.

Tesla said Wednesday it will start selling its Cybercab to customers by the end of the year, even as federal regulators investigate whether the vehicle meets vehicle safety standards. The gold-hued, autonomous two-seater lacks a steering wheel and other traditional controls. During the company’s third-quarter earnings call, Lars Moravy, vice president of engineering at Tesla, […]

The documented raw balance is a UInt256String: an unsigned integer string that can reach 78 digits. When you display one in Python, Decimal looks like the obvious tool. The trap is subtle: building a Decimal from a string is exact, but arithmetic on it can round. Where the rounding happens Decimal(raw) keeps every digit, because construction ignores the context precision. Operations such as scaleb , normalize , multiplication, or division round their result to the context...

I built a 1,000-record synthetic benchmark for phishing detection — here's what 2 open models scored The problem I run a YouTube channel where we test AI claims with real experiments. For an episode on phishing detection, I went looking for published scam/phishing-detection scores for open-weight models. There were none. Zero. For any of them. So we built the benchmark ourselves. RSB-1000: what it is 1,000 records , fully synthetic (every brand, domain,...

How to Maintain RAG Freshness in Production Your RAG system can look healthy while serving old answers. Source data changes, users keep querying, and the retrieval layer quietly drifts out of sync. By the time someone notices, trust is already damaged.

CGT Rocket X Racer is a fan-made, desktop-only rocket-car runner we have been building in Godot 4. It is not affiliated with any car maker. You steer a hovering car through a giant factory: lane changes, jumps, rolls and a boost, with presses and robot arms trying to ruin your run. This post is about three problems that turned out to matter far more than we expected: making the car feel airborne, switching between indoor and outdoor sections without breaking the camera, and proving that every ob...

On October 21, 2026 , PHP shipped an emergency security release for two critical vulnerabilities in the PHP runtime itself . The pair is being called PHP2Shell : CVE-2026-109618 CVE-2026-109619 Both have a 9.2 Critical CVSS score. Both can expose vulnerable PHP services to unauthenticated remote code execution and memory disclosure. And neither one is fixed by updating Laravel, WordPress, Symfony, a Composer package, or your application code. This is the important ...

A series of articles that takes you through the concepts used in KMDS - it is a 10000 ft view, but it gives you the ideas used: AI view versus data science view to building intelligent solutions: AI vs Data Science Going from a business use case to a data science task view of the data: kmds-dataset-util Going from a task view to a dataset that is ready for modeling and featurization: dd-parser-cleaner Going from a modeling/featurization ready dataset to features and models f...

Most face shape tools give you a label and a list of haircuts. I wanted to build the opposite: something that shows the five measurements behind the label, then keeps going into the questions people actually have afterwards. Try it here: knowyourfaceshape.com — free, no sign-up, and your photo never leaves your browser. What it does You can get your face shape three ways: upload a photo, take a 60-second quiz, or enter four tape-measure readings. The photo path runs MediaPipe Face Lan...

Picture a device running smoothly for months, then suddenly missing its communication window once every few thousand cycles. The logs show no obvious errors. The question arises: was the work late, or was it slow? This article explores a technique to distinguish between these two possibilities, providing insights that logs alone cannot offer. why logs and averages miss this Logs typically record discrete events, not the duration of tasks, making them inadequate for diagnosing tim...

MCP Step-Up Authorization vs. OAuth Incremental Authorization: What Actually Changes? “There are no zones.” There were three. TL;DR When Cloudflare announced step-up authorization for its API MCP Server, I wanted to know how it differed from Google OAuth's Incremental Authorization. I read the specs, wrote my own MCP client, and sent 128 requests to the live service. The additional authorization itself is still ordinary OAuth. The difference is a path for the server to t...

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 3: Slow and Steady What I Built Meet SlothAI 🦥 — an offline, local-first web companion designed for anyone who believes sloths have life figured out. Instead of paying recurring cloud subscriptions or giving away personal correspondence to remote servers, SlothAI runs open-weight models (like Llama 3.2 ) locally on your hardware via Ollama . It packages 6 micro-tools dedicated to taking over the te...

Apple's iPhone Duo goes on sale on Friday 23 October. 6pm, our daily money app, already lays itself out for each way you can hold it. We built it in mid-October on the iPhone Duo simulator in Xcode 27.1, and it ships in 6pm 2.0.0 on the App Store on 6 November. This post covers what the iOS 27.1 SDK gives you, how we got it into React Native, and the one design question that took the most thought: what should folding a phone shut mean in an app you close once a day? Every snippet is from...

Hi HN! We’re Srikar and Kevan, founders of Alter – https://alterauth.com/ . We’re building access control for agents that can take actions on behalf of multiple users. If you’ve built an internal agent people use through Slack, you may have experienced this scenario: everyone signs in with their own account, but the agent connects to the CRM or billing system with one shared API key, so the agent can do anything that the key can do. User-level authentication in Slack does nothing to control wha...

Hey all, Kartik from Omnara ( https://omnara.com ) here. We're building an open-source API for running durable agents. You create an agent with an API call, and Omnara runs the agent loop, gives the agent sandboxes to run commands in, and handles secrets, permissions, and RBAC. Each agent's state is stored in Postgres, so agents survive restarts and cost nothing while idle. You can message them and stream their events over the API. You may remember us from our early days, when we made a remote-c...

Cloud infrastructure engineering has advanced through successive layers of abstraction, but declarative IaC fundamentally answers only one static question: "What infrastructure should exist at deployment time?" Modern distributed systems expose the limits of this static paradigm, requiring a shift to closed-loop, governed autonomous platforms.

Substantive human oversight requires a 4-part escalation layer: bi-directional transparency, granular controls, context routing, and auditable feedback loops.
