This calculator uses Interval Union Arithmetic to compute results that contain the true value, supporting division by intervals with zero and remaining closed. It interprets numbers as intervals with outward rounding over IEEE 754 double precision floats.
Claude Design is a new product that lets users collaborate with Claude to create visual work like designs, prototypes, and presentations. It's available in research preview for Claude Pro, Max, Team, and Enterprise subscribers, with access included in their plans.
Emacs 30 introduced a trust system to prevent arbitrary code execution, but it causes friction by disabling features for untrusted files. trust-manager is a new package that grants trust just-in-time with minimal friction.
Anthropic's new Claude Opus 4.7 tokenizer uses 1.3-1.45x more tokens than 4.6. This results in a 20-30% higher per-session cost for a small but real improvement in instruction following.
Lunar dust is toxic and causes health issues in humans due to its sharp, abrasive particles and electrostatic charge. Researchers are studying the dust to estimate the risk and develop protective measures for future lunar missions.
The author is on a 6-week retreat at the Recurse Center to focus on coding without AI, learn Python, and understand computers better. They plan to train an LLM from scratch and improve their programming skills.
Fil-C is a memory-safe implementation of C/C++ that uses a garbage collector and rewrites unsafe code into safe code, including adding AllocationRecord* variables to track memory usage. The simplified model of Fil-C includes a compiler pass that rewrites C/C++ source code, a garbage collector, and additional features such as invisible_bytes and a parallel concurrent incremental collector.
The author questions the trend of AI's exponential growth in task length and performance, suggesting that the cost of achieving this performance may be growing exponentially as well, potentially making AI less cost-competitive with humans over time. Analysis of a chart from METR shows that the hourly cost of AI agents is increasing with task duration, suggesting that forecasting AI's ...
A series of characters ask a computer, Multivac, about the possibility of reversing entropy and extending the life of the universe, but it responds with "insufficient data for a meaningful answer." As the universe runs down, a cosmic computer, AC, eventually learns how to reverse entropy, but there is no one left to answer the question.
Smolmachines is a tool for running custom Linux virtual machines locally with sub-second cold start, cross-platform support, and elastic memory usage. It allows for sandboxing untrusted code, packing workloads into portable executables, and using git and SSH without exposing keys.
Slop Cop is a browser-based writing editor that flags generic LLM prose patterns and offers deeper analysis with an Anthropic API key. It helps improve writing by identifying and suggesting edits for common structural and rhetorical issues.
PanicLock is a macOS utility that instantly locks the screen and disables Touch ID with a single click or laptop lid closure. It requires a one-time admin password setup to install a privileged helper tool.

iTerm2's SSH integration feature can be exploited by impersonating the remote conductor through terminal output. This allows an attacker to execute arbitrary commands on the local machine.
Researchers found 479 gene variants that evolved through natural selection in ancient people from western Eurasia after the dawn of agriculture, leading to widespread health changes in present-day populations. The study suggests human evolution accelerated over the past 10,000 years, particularly during the Bronze Age, with changes in genes linked to immunity, skin tone, and other traits.
NASA Force is a hiring initiative for exceptional technologists to join NASA for 1-2 years, solving complex challenges in air and space. You'll work on real missions, take a systems approach, and contribute to advancing human spaceflight and scientific discovery.
A 13-year-old in Berlin discovered a 2,300-year-old bronze coin from ancient Troy, now on display at the PETRI Museum. The coin likely traveled along ancient trade routes, possibly kept as a charm or offering to the dead, rather than used for a business transaction.
Casus Belli Development is a social mechanism where a perceived failure is used to replace a working system with a preferred worldview, often driven by individuals who use narrative to construct guilt and manipulate the system. This mechanism exploits cognitive biases and organizational dynamics, leading to the destruction of proven foundations and the perpetuation of root causes, and can be ...
The user created a fictional programming language called Brunost, which is based on the Norwegian language Nynorsk and has a unique syntax and features. Brunost is intended as a fun and educational project, not a production-ready language, and the user invites others to contribute to its development on GitHub.
Our wax seal mailing service helps you send custom wax sealed letters at scale. We print, hand-seal with your logo, and mail each piece for you. We started in a small apartment, sending letters for another business idea. That's when I discovered that the personal touch of a wax seal made the biggest difference in response rates. I started making simple systems to produce as many wax seals ...
The US National Institute of Standards and Technology (NIST) has announced a new policy to prioritize only important vulnerabilities in the US National Vulnerability Database due to budget constraints. This decision is expected to impact the cybersecurity industry, with some companies relying on NIST's data for their vulnerability scanners and dashboards.
The author released ShaderPad, a library for easily putting shaders on websites without rebuilding graphics scaffolding. It's designed for artists and creative coders, with a simple API and fast page loads due to its small size.

The role requires a senior engineer to own and evolve the platform behind ARC-AGI benchmarks, stabilizing the current system and laying the foundation for future versions. The ideal candidate has strong backend engineering experience with Python and distributed systems.
The user developed a color spectrum visualization tool called Spectrimage that displays the frequency and tonal range of each hue in an image, with a unique design for black and white photographs. The tool analyzes the image client-side in the browser, converting pixels to HSL, sorting and averaging colors, and rendering the spectrum on an HTML Canvas in under a second.
Anubis is a server protection system that uses a Proof-of-Work scheme to prevent aggressive website scraping. It adds a load that makes scraping expensive, but may cause downtime for legitimate users.
The US needs to clamp down on the collection and sale of geolocation data to protect national security and privacy, as seen in the case of Webloc, a tool used by US and foreign authorities to track individuals. A new report highlights the risks of AI-powered hacking, as a single hacker used AI models to breach nine Mexican government organizations and steal hundreds of millions of citizen records.
Stage is a platform for fast-moving teams that breaks down pull requests into structured chapters. It provides a unified dashboard to review pull requests with context and chapters at a glance.
The author started a 3D printing business making custom card stands for a neighbor's trading card business. The business worked for a while but eventually hit scaling issues due to limitations in the printing process.
In 2024, Ben Lerner was asked if he wanted to interview one of his mentors, the poet Rosmarie Waldrop, for The Paris Review. “I was really ambivalent about it,” Lerner told me. “Rosmarie is amazing. She’s a hero of mine. But she’s not very easy to interview, in part because one of her remarkable characteristics is she doesn’t just bullshit.” That conversation was an origin point for his new ...
