The author recounts their lifelong obsession with Tetris and describes their quest to see every possible state of the game, using Antithesis software to explore its deterministic gameplay and uncover the game's full combinatorial depth.
Background
- Tetris has been released in hundreds of versions across every platform imaginable. They all share the same basic idea but differ drastically in physics, controls, and visual feel — quirks like "wall kicks" (how blocks rotate near walls) and "lock delay" (how long a block sits before locking) vary from port to port.
- This post recounts one person's quest to play every commercially released Tetris, discovering how differently each one plays.
- The blog is from Antithesis, a company that makes automated software testing tools. The Tetris fragmentation serves as a metaphor: small, undocumented differences between supposedly "identical" systems can cause surprises in testing.
- Competitive Tetris recently went viral: in 2024, a 13-year-old known as "Blue Scuti" became the first person to crash the original NES Tetris at level 157, effectively "beating" it.
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.
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.
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.
