A new project called 'How Stale Is Your AI?' compiles release dates and training cutoffs for 20 models from 8 major labs, sorted from stalest to freshest. It finds that only 9 of the 20 models have a training cutoff date that is actually published by their maker, with data also offered as a downloadable models.json file.
A developer known as GraafHenk has published an open-source project called Numberwang, built around a tiny 1.8MB JSON model and roughly 100 lines of pure Python with no external dependencies. The tool parses digits, number words, arithmetic expressions, Roman numerals, currencies and more across eleven languages, then returns one of four comedic verdicts inspired by the British sketch of the same name, including 'Numberwang' and 'Wangernumb'. It runs via command line or can be imported directly as a Python function returning probability scores for each verdict.
A developer has released StemJSON, a JSON-based declarative language designed specifically for AI systems to generate native mobile app interfaces and logic. It can be used to build entirely new apps or to extend existing ones, and is intended to plug into AI tools, prototyping environments, or IDE extensions. The format is open, meaning it can be freely adopted alongside hand-written code in development workflows.
gPTY is a new open-source project that pairs the Godot game engine with Rust to create a PTY-based terminal multiplexer featuring a resizable tiling grid for panes like terminals, code viewers, and file trees. It exposes a JSON-RPC/CLI/MCP control interface so AI agents and scripts can spawn panes, inject text, and read output programmatically instead of scraping terminal UIs. It also includes a regex-based 'concept engine' that captures and routes terminal output into other panes, plus persistence via SQLite/JSON for scrollback, settings, and workspaces.
A developer commentary questions why so many software tools rely on JSON for configuration files despite JSON's inability to natively support comments. The piece argues this makes it difficult for users to document why specific settings were chosen, a basic need in configuration management.
A blog post highlights a handy jq trick from Sequoia McDowell that pretty-prints JSON copied to the clipboard and pastes it back automatically, using pbpaste and pbcopy on macOS. The author adapts this for Linux using xclip, then identifies a flaw: if the clipboard doesn't contain valid JSON, jq fails silently and wipes the clipboard content. The fix adds a fallback so the original clipboard text is preserved when jq errors out.
AC2 is a new open protocol designed to let AI agents request verifiable human sign-off before taking consequential actions, such as merging code, sending client messages, calling APIs, or executing payments. It installs into existing frameworks via a plugin and single command, using DIDComm v2.0 messaging and passkey authentication through Liquid Auth (FIDO2/WebAuthn), without needing a central relay server or blockchain.
Confdiff is a command-line and browser-based tool that compares JSON, YAML, TOML, INI, .env, properties, CSV and XML files by parsing them into a data model rather than comparing raw text. This lets it ignore cosmetic changes like key reordering, reformatting or added comments while flagging genuine differences, including type changes such as a number becoming a string. A --redact flag masks secret values with stable fingerprints so teams can see that credentials changed without exposing the actual values in a PR or CI log.
A developer released GlassBox, a Show HN project that runs live in a browser to capture the same fingerprinting signals used by tracking and anti-fraud scripts, then displays them to the user instead of hiding them. Users can also paste a JSON report from another browser or session to compare fingerprints, and GlassBox scores similarity to indicate whether the two reports likely come from the same machine, engine family, or browser.
