Universal Tool Calling Protocol (UTCP)

Universal Tool Calling Protocol (UTCP) 1.0.1 Introduction The Universal Tool Calling Protocol (UTCP) is a modern, flexible, and scalable standard for defining and interacting with tools across a wide variety of communication protocols. UTCP 1.0.0 introduces a modular core with a plugin-based architecture, making it more extensible, testable, and easier to package. In contrast to other protocols, UTCP places a strong emphasis on: Scalability : UTCP is designed to handle a large number of tool

Fennel libraries as single files (2023)

I’m pleased to announce that most of my libraries for fennel are now shipped as single files! It was a long-standing issue with Fennel for me, as there was no clear way to ship both macros and functions in the same file, but after some experimentation, I figured out a way. After a bit of testing with my new library for asynchronous programming I can say that it works well enough to be used in most other libraries. Although the implementation is a bit rough and manual, that’s what I’ll try to des

The Rubik's Cube Perfect Scramble

The Challenge I was playing with my son’s Rubik’s Cubes and tried to scramble a cube randomly so that no two squares with the same color were side by side. Here’s one way to do it: But I wanted a scramble that looked like a random scramble. No matter how many different moves I made, I couldn’t do it. Every time I separated two squares with the same color, two other squares of the same color would touch somewhere else. Looking for an easy answer, I went to puzzling.stackexchange.com an

Can your PC run Battlefield 6? Full system requirements and multiplayer details revealed

What just happened? Most big PC releases these days come with the anxiety of whether your PC will be able to play them well – or at all. Thankfully, Battlefield 6's just-revealed PC requirements are pretty forgiving. DICE and EA have also unveiled a slew of extra information about the FPS, including more on its multiplayer element and next month's Open Betas. Battlefield 6's minimum system requirements ask for at least an RTX 2060, RX 5600 XT 6GB, or Intel Arc A380 paired with an Intel Core i5-

Extending Emacs with Fennel (2024)

After watching this year’s EmacsConf and seeing Guile Emacs being resurrected I thought to myself - why limit ourselves to Guile? Sure, Guile isn’t just a Scheme implementation, thanks to its compiler-tower-based design. Other languages exist for Guile VM, such as Emacs Lisp, and Guile manual lists the following languages with various stages of completeness: ECMAScript Brainfuck Lua Ruby Python Sure, it would be nice, if Emacs could natively run all of these, but we have to understand, tha

Kiro: A new agentic IDE

I’m sure you’ve been there: prompt, prompt, prompt, and you have a working application. It’s fun and feels like magic. But getting it to production requires more. What assumptions did the model make when building it? You guided the agent throughout, but those decisions aren’t documented. Requirements are fuzzy and you can’t tell if the application meets them. You can’t quickly understand how the system is designed and how that design will affect your environment and performance. Sometimes it’s b

US appeals court blocks FTC’s ‘click-to-cancel’ rule for subscriptions

In Brief A U.S. appeals court has blocked the Federal Trade Commission’s “click-to-cancel” rule that would have required companies to make it as easy to cancel a subscription as it was to sign up. The rule was set to take effect on July 14. Reuters reports that the 8th U.S. Circuit Court of Appeals in St. Louis said on Wednesday that the FTC, which passed the rule under former Democratic Chair Lina Khan, had failed to conduct a preliminary analysis of the costs and benefits of the rule. The r

The FTC's 'Click to Cancel' Rule Is Blocked. Here's What That Means for Your Subscriptions

The Click to Cancel rule is supposed to make it as easy to cancel a subscription as it is to sign up for one. Viva Tung/Getty Images The Federal Trade Commission's "click to cancel" rule -- which would have made it easier to cancel unwanted subscriptions -- has been blocked by the US Eighth Circuit Court of Appeals. The rule was set to take effect on July 14. "Click to cancel" would have required businesses to clearly disclose terms and obtain informed consent before charging for a subscriptio

Borderlands 4 recommended specs call for an RTX 3080 and 32GB RAM

A hot potato: Now that people are no longer angry over Borderlands 4 possibly costing $80 (it's actually $70 for the standard edition), something else is causing plenty of outrage: the game's PC requirements. Asking for an RTX 3080 as the recommended GPU does seem excessive, and even the minimum specs are higher than expected. Borderlands 4's system requirements on its Steam page are certainly higher than one would expect. Even the bare minimum requirements, where we usually see ancient and/or

Using computers more freely and safely (2023)

How can we use computers more freely and safely? the punchline Prefer software: with thousands rather than millions of users that seldom requires updates that spawns lots of forks that is easy to modify that you can modify These are my suggestions. Prefer software with thousands rather than millions of users, that doesn't change often, that seems to get forked a lot, that can be modified without specialized tools, and, ideally that you can make small changes to.

IBM announces new quantum processor, plan for Starling supercomputer by 2029

Parts of the IBM Quantum System Two are seen at IBM Thomas J. Watson Research Center in Yorktown Heights, New York, on June 6, 2025. IBM on Tuesday announced a roadmap to develop a large-scale, fault-tolerant quantum computer called Quantum Starling. Part of the company's plan involves the new IBM Quantum Nighthawk processor, which is set to release later this year, according to a blog post announcing the details. "Unlocking the full promise of quantum computing will require a device capable

Emulators for Android: Can your phone handle these consoles?

There are loads of brand new games on the Google Play Store, and you can find plenty of retro titles too. But what if your favorite classics aren’t available on Google’s app store? That’s where emulators come in. Emulators let you play console games from past generations (or current) on modern hardware, including smartphones.
