The jank Programming Language [book]

The jank programming language book provides documentation and reference material for jank, a new programming language designed to be a pragmatic, functional-first language that compiles to native code and leverages Clojure-inspired syntax with C++ performance.

Background

- **jank** is a new, experimental programming language that aims to combine the performance of C++ with the expressive power and interactive development workflow of Clojure (a modern Lisp dialect that runs on the JVM, JavaScript, and other platforms). It is being built from scratch by a small open-source team led by Jeaye Wilkerson. - Unlike most Lisps, jank is compiled ahead-of-time (AOT) to native machine code via LLVM (the same compiler infrastructure behind languages like Rust and Swift), rather than running on a virtual machine or interpreter. This is intended to give it startup times and runtime speed comparable to C or C++. - The project is currently in early development (pre-1.0) and does not yet have a stable release. Its "book" serves as both documentation and a reference for its unique design choices. - jank matters because it represents a bet that a Lisp syntax (known for metaprogramming and live coding) can be practical for systems-level work — an area long dominated by statically typed, low-ceremony languages like C, C++, and Rust. If successful, it could offer a middle ground between developer ergonomics and machine efficiency.

Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
Statement on the US government directive to suspend access to Fable 5 and Mythos 5

The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.

Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.

Roman Storm warns that the legal theory in his case could set a precedent making open-source developers liable for how others use their code, potentially criminalizing the mere publication of privacy, messaging, or crypto tools. He notes that developer Michael Lewellen cannot publish lawful code due to prosecution fears, and argues this chilling effect extends beyond any single case.
‘Why Is Meta Destroying Its Engineering Organization?’
8.5
Meta's engineering culture is deteriorating under Mark Zuckerberg and Scale AI CEO Alexandr Wang, who have introduced keyboard tracking, reassignments to data labeling, and AI-centric performance metrics. Critics argue this incentivizes performative AI use, drives away experienced engineers, and contributed to a major Instagram hijacking incident caused by AI-written and AI-reviewed code.
