The team created a virtual filesystem called ChromaFs to power their documentation assistant, allowing it to explore documentation like a codebase without the need for real sandboxes. ChromaFs uses a Chroma database to provide instant session creation, zero marginal compute cost, and built-in role-based access control, replacing the need for expensive sandboxes.
A secure coop door design uses a vertical sliding door with a self-locking mechanism, eliminating the need for external locking. The door is designed to be easy to build using a jigsaw, drill, and table saw, with a counterweight or spring hinge for smooth operation.
The user had trouble removing Samsung Magician, a disk utility software, from their Mac due to its poor uninstallation process. They had to use multiple commands and even disable and re-enable System Integrity Protection to delete the remaining files.
To make async Python workflows deterministic, we need to understand the event loop's single-threaded execution model and how tasks are scheduled in FIFO order. By incrementing step IDs before the first await in each step, we can deterministically order steps and ensure consistent execution order during recovery.
A US F-15E Strike Eagle fighter was shot down over Iran, prompting a US search and rescue effort for its two crew members. One crew member was reportedly rescued in a high-risk operation, with the fate of the second crew member still unclear.
RepoProver is a multi-agent scaffold for formalizing math textbooks in Lean, using LLM agents for translation, proof, and review. It uses a shared git repository and lightweight issue tracker for coordination.
Amazon's AWS availability zones in Dubai and Bahrain are down due to Iranian strikes and will be unavailable for an extended period. Amazon is advising employees to deprioritize the regions and is helping customers migrate to other locations.
The Model Context Protocol (MCP) released its 2026 roadmap focusing on scalability, governance, and enterprise readiness. MCP faces security concerns and usability improvements are being made through simplified integrations and documentation.
The user set up a local dial-up ISP using a Raspberry Pi and an old modem to emulate a dial-up connection on an iBook G3 from 1999. They used a phone line simulator and a USB modem to establish a connection and browsed the internet using Macproxy Classic.
I've decided to share my DCJ11 based board. It's based heavily on the word done by Beent Hilpert http://madrona.ca/e/pdp11hack/ but I wanted to able to add and remove functionality via a back plane. I've long admired this chip for no other reason than it looks so freekin' cool, I mean just look at it, it's gorgeous. So far There is the main CPU board and also the RAM, ROM ...
TurboQuant compresses high-dimensional vectors to 2-4 bits per coordinate with near-optimal distortion. It's online, zero-training, and faster than FAISS IndexPQFastScan on ARM and within 18-25% on x86.
SSH certificates provide a better and more seamless SSH experience by eliminating the need for Trust on First Use (TOFU) and allowing for short-lived keys, forced-commands, and automated key management. An SSH CA can be used to sign host keys and user keys, making it easier to manage SSH connections and eliminating the need for manual key deployment and TOFU.
Via LA restructured H.264 streaming license fees in a tiered system topping at $4.5 million per year for large platforms. The change applies to new license seekers in 2026 or later, not affecting existing license holders.
A Python CLI uses neural linguistic steganography to hide data in recipe blog introductions. It encodes data as natural language using arithmetic coding steganography, requiring the same model and prompt for decoding.
You initially suspected eBay scammer but received an automated email stating their account was suspended. Now you plan to re-list the watch at a discounted price.
The author analyzes the structure of dataframes and identifies three fundamental operations: Delta (restructuring), Sigma (merging), and Pi (pairing), which can be used to build a dataframe algebra. Category theory provides a framework for understanding these operations and their relationships, allowing for a more principled design of dataframe libraries.
Espressif Systems announces ESP32-S31, a high-performance SoC with Wi-Fi 6, Bluetooth 5.4, and Ethernet for IoT applications. It features a dual-core RISC-V microcontroller, robust security, and comprehensive connectivity for smart appliances and industrial automation.
apfel is a CLI tool that exposes Apple's built-in LLM on Macs with Apple Silicon. It provides a way to access the LLM through a terminal, code, or chat, without network calls or API keys.

Trigger Words Indentification. To identify potential trigger words, was first conduct a word frequency analysis across both benign and injection datasets. The words are then ranked according to their frequency within each dataset, sorted separately for benign and injection datasets. By calculating the differences in word rankings between the two datasets, we highlight words that are ...
Type theory is a mathematical theory that is an alternative to set theory and category theory, and it is used to define collections of objects that are interesting without accidentally defining collections that lead to paradoxes. Type theory is based on the idea that the interesting collections are the source and target of functions, and it is used to define types and functions in a way that ...
