Show HN: ChDB-WASM – ClickHouse running in the browser via WebAssembly
ChDB-WASM brings ClickHouse, a fast SQL analytics database, directly into the browser using WebAssembly. This allows users to run SQL queries on large datasets locally without a backend server, leveraging ClickHouse's columnar engine for performance.
Background
- ClickHouse is a popular open-source column-oriented database known for its speed in analytical queries (large-scale data aggregation, not row-by-row transactions). It is normally a server-side system.
- chDB is a lightweight, embeddable version of ClickHouse (like SQLite is for traditional databases). It lets developers run ClickHouse-style SQL inside their own programs without a separate database server.
- This project compiles chDB into WebAssembly (WASM), a binary format that modern browsers can execute at near-native speed. That means ClickHouse's analytical SQL engine now runs entirely in a web page — no backend server needed.
- The demo lets you query in-browser CSV/Parquet data using ClickHouse SQL dialect, making it useful for prototyping, data exploration, or edge cases where sending data to a server is undesirable (privacy, latency, offline use).
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.
