We measure IPv6 connectivity among Google users, showing deployment and reliability issues in various regions. Regions with high IPv6 deployment have fewer issues, while those with low deployment experience significant problems.
Darkbloom is a decentralized AI inference network connecting idle Apple Silicon machines to demand, reducing costs by up to 70% and giving operators 95% of revenue. It ensures end-to-end encryption and operator anonymity, eliminating data extraction risks.
This post documents our research into using AI to hack hardware devices. We'd like to acknowledge OpenAI for partnering with us on this project. No TVs were seriously harmed during this research. One may have experienced mild distress from being repeatedly rebooted remotely by an AI. We started with a shell inside the browser application on a Samsung TV, and a fairly simple question: if ...

Ancient DNA has transformed our understanding of population history1, but its potential to reveal as much about human evolutionary biology has not been realized because of limited sample sizes and the difficulty of distinguishing sustained rises in allele frequency increasing fitness—directional selection—from shifts due to migrations, population structure, or non-adaptive purifying or ...
Anthropic's Mythos LLM is highly capable at computer security tasks, completing a simulated corporate network attack in 3 out of 10 attempts. Security may be reduced to a simple equation of spending more tokens than attackers to harden a system.

The user wants to combine physical and virtual worlds to reduce screen time and distractions, allowing for flexibility and convenience. They envision a future where technology helps people work and interact without constant screen interaction.
The XOR swap trick is not useful in most programming situations due to compiler optimization. It can be useful in assembly code when swapping values in registers without spare registers.
This clock displays the current time alphabetically. It is inspired by this post on Mastodon. In Three-Hand mode, the hours, minutes, and seconds are each independently sorted by their English spelling, with a hand for each.In Combined mode, every possible time (43,200 of them) is spelled out, sorted alphabetically, and a single needle points to the current one.
NaviDial is a service in Japan where businesses and public services charge callers for calls, often resulting in high costs for those who need help the most. To avoid these costs, international residents in Japan can look for alternative numbers, use text-based support, or ask for a callback when calling from a mobile phone.
FIXAPL is a simple array-oriented programming language with fixed-arity functions and trains for tacit programming. It draws inspiration from BQN, Uiua, and TinyAPL, with a new idea of fixed-arity functions as a beautiful enhancement to tacit programming.

RamAIn is a YC W26 company that builds AI agents for enterprise work, eliminating repetitive workflows. They're hiring a generalist for go-to-market, sales, and operations to work directly with the founders.
The user compares two methods for finding the closest matching word in a large dictionary using Levenshtein distance, with the second method using a trie data structure being over 300 times faster than the first. The second method has a runtime of O(max word length * number of nodes in the trie), making it more efficient for large dictionaries.
Dr Patterson's work includes articles on processor design, compiler optimization, and software development, used by universities and startups worldwide. His research covers topics from instruction scheduling to executable optimization and open-source software impact.
Ask ChatGPT to build full spreadsheets, get insights across tabs and formulas, and update workbooks in real time so projects move forward faster. Available globally for ChatGPT Business, Enterprise, Edu, Teachers, and K-12 users, and for ChatGPT Pro and Plus users outside the EU.
Rick Aschmann created a map of North American English dialects with clickable states and provinces, allowing users to listen to audio or video samples of local dialects. The map is based on data from the Atlas of North American English and has been updated with contributions from users, with over 900 samples listed.
Airbnb migrated its metrics pipeline from StatsD to OpenTelemetry and Prometheus, collecting all metrics first to focus on technical challenges. The new pipeline uses a dual-write strategy, OTLP for internal services and Prometheus for OSS workloads, with a centralized aggregation tier for cost savings and scalability.
Cal.com is moving to closed source due to increasing security risks from AI-powered vulnerability scanning. They're releasing a modified open source version, Cal.diy, under the MIT license for developers and hobbyists.
Google handed over Amandla Thomas-Johnson's data to ICE without notifying him, breaking a nearly decade-long promise to users. The Electronic Frontier Foundation has asked California and New York Attorneys General to investigate Google for deceptive trade practices.
The user built a reusable viewport component in Go for text navigation in terminal applications and used it to create a terminal pager called lore, which they now daily drive as their terminal pager. The viewport component supports features like text wrapping, search, and selection, and is designed to be performant even with large amounts of text.
Spherical harmonics are a set of special polynomials that can be used to approximate any continuous function defined on a sphere. They are an orthonormal basis for the space of continuous functions on a sphere, meaning that any function can be expressed as an infinite weighted sum of spherical harmonics.
yk is a system that automatically converts C interpreters into JIT compiling Virtual Machines with minimal code changes, offering better performance while retaining full compatibility with reference implementations. yk uses meta-tracing to record and optimise the interpreter's actions, allowing it to inline code and achieve significant performance improvements with minimal manual effort.
