Ask HN: Which GitHub features are needed in a code forge before you can migrate?
A developer building a new code forge called juju.bi is asking the Hacker News community which GitHub features are essential blockers for migrating to a different platform. The forge prioritizes offline collaboration, GitHub API compatibility, and change-ID-based features (like Jujutsu's evolog). The creator is currently focusing on small teams with private repos before expanding to public repos.
Background
- A "code forge" is a platform for hosting source code and collaborating on it — GitHub, GitLab, Bitbucket, and SourceHut are examples. This post asks which features would keep a team from switching away from GitHub, the dominant forge owned by Microsoft.
- Jujutsu (or "jj") is an emerging version-control system designed as a modern alternative to Git. "Change-id based features" (like jj's "evolog") track a commit's identity across edits and rebases, enabling cleaner history rewriting — something Git struggles with.
- The author is building juju.bi, a new forge that works offline (many forges require a connection to browse code or file issues), is API-compatible with GitHub (so existing tools still work), and natively supports jj's model.
- "S3 compatible" refers to how many cloud storage services adopt Amazon S3's API so existing software works without changes — the author wants GitHub API compatibility to work the same way.
- The post is an "Ask HN", a community thread on Hacker News where someone poses a question to the tech audience.
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.
