uvm32 is a minimalist C99-based virtual machine for microcontrollers offering a RISC-V emulator with a management interface. It aims for safety over speed and is designed for executing custom scripts, not hardware simulation.
capsudo is a project that reframes privilege escalation as a mediated interaction with a service called capsudod, providing narrowly scoped capabilities. This object-capability model makes privilege boundaries visible, composable, and easier to reason about, shifting from identity to possession.
Bidicalc is a spreadsheet-like tool that allows changing the output of a formula and updating the inputs to match the formula, with a custom root-finding solver for backward updates. The tool is open-source, written in TypeScript, and has limitations such as floating point precision and available computation time, with potential improvements in domain restriction, solver, and UX.
The US President issues an executive order to promote national and economic security through AI leadership, and to prevent State laws from hindering innovation. The order establishes a task force to challenge conflicting State laws and proposes a national framework to ensure AI dominance.
Formal verification has made significant progress over the past 50 years, from initial proof assistants like LCF and HOL to modern systems like Isabelle and Coq. Today, proof assistants are used in various applications, including hardware verification, cryptographic protocols, and even operating system kernels, with AWS and Apple using them in their products.
The user built a smart home platform with Home Assistant but struggled to find a compatible humidifier, so they decided to modify a Xiaomi Mi Smart Antibacterial Humidifier with ESPHome firmware. They disassembled the humidifier, removed the WiFi module, and prepared it for flashing with a new firmware using ESPHome's build-in web flasher or esptool.py.
The EU's electronic invoicing system has security flaws due to its design and use of vulnerable technologies like XML and Saxon. Implementing software for electronic invoices may be affected by security flaws if no countermeasures are implemented.
We thought Go would give us a single, portable agent binary for every Linux distro. Turns out… not exactly. But also, kind of yes. This post kicks off a series about the traps we fell into while building a cross-platform server monitoring agent. First, some theory. simob is our open source server monitoring agent that powers the Simple Observability platform. We like to think of it as a ...

Motion is building an end-to-end agentic work suite with AI agents at its core, aiming to boost productivity by an order of magnitude. The company is seeking a senior frontend engineer to drive major technical initiatives and make lasting technical decisions.
Here's a summary of the user's input in 2 concise English sentences.
The user discusses various optimizations to the median filter algorithm, including quick selection, multi-threading, and ordinal transform, which result in significant speedups, with the final version achieving a 420 times speedup over the baseline. The user also mentions further optimizations for uint8 datatypes, including Huang's Algorithm, Median filtering by localization, and Moruto's ...
The author is building a Go service at a Python shop and chose Go due to its ease of use and speed. They're using Docker and Docker Compose for the project.
ClickHouse Cloud has released pg_clickhouse v0.1.0, a PostgreSQL extension to execute analytics queries on ClickHouse directly from PostgreSQL, simplifying workload migration. The extension provides near universal pushdown for analytics queries and aggregations, improving performance and efficiency for complex queries.
To avoid smart TV tracking and ads, consider using a non-smart TV, such as an Apple TV box, a laptop, or a projector, or opt for a digital signage display, but be aware of potential image and sound quality tradeoffs. Alternatively, you can use a TV antenna to watch free, untracked TV channels, but be aware of limitations such as limited channel selection and potential performance issues.
Home Depot employee's exposed GitHub token granted access to private source code and cloud infrastructure. Home Depot did not respond to security researcher's emails, but the token's access was revoked after TechCrunch outreach.
Mathematicians have made a major breakthrough in classifying polynomial equations, using techniques from string theory to prove that four-folds are not parameterizable. The proof, posted in August, has sparked excitement and skepticism among the mathematical community, with many experts struggling to understand the new techniques.
A JetBlue flight from Cancun to New Jersey dropped altitude due to a computer malfunction caused by cosmic radiation. The incident led to a mass grounding of over 6,000 aircraft for software updates to protect against space radiation.
The Raspberry Pi CM0 is a small Linux computer with WiFi, eMMC storage, and castellated edges for easy integration. It's only available in China, possibly due to supply chain issues with the LPDDR2 RAM chip used in the RP3A0 SoC.
The user is trying to handle async DNS requests using various methods in C. They need a method without background threads, signals, or secret mechanisms.
The Commodore 64 Maze Chomp game uses POKE statements and variables to set border, background colors, and character positions. The game logic includes key input, boundary checking, scoring, and time display, resetting with a score of 0 and background color change.
Microservices can be complex and difficult to manage if not structured properly, leading to issues like cyclical dependencies and tangled responsibilities. A polytree structure, where services form a directed acyclic graph, can help avoid these problems by enforcing clear ownership of state, predictable failure modes, and independent evolution.
Researchers are developing ways to teach about AI using school math. A team, CAMMP, has created materials using data-driven technologies to demystify AI and show students how to build AI systems using existing math concepts.
The author learned about "take-and-take" in an improv comedy show, where one person sings until another jumps in, and applied it to conversations, realizing that "givers" and "takers" have different approaches.
When I started building Fedify, an ActivityPub server framework, I ran into a problem that surprised me: I couldn't figure out how to add logging. Not because logging is hard—there are dozens of mature logging libraries for JavaScript. The problem was that they're primarily designed for applications, not for libraries that want to stay unobtrusive. I wrote about this a few months ago, ...
Fedora is a sustainable open-source repository system for digital libraries and archives, designed for institutions to preserve and provide access to digital content. It's a community-driven project with a 20+ year history, offering a transparent persistence layer and various community resources.
