  • Nintendo 64 Java
    There's been plenty but they've fallen aside for various reasons. - GCJ (iirc only pre 1.5-1.6 java support so never with generic versions, not sure if they ever implented JNI but relied on their own so libraries with native bindings had to be manually ported iirc) - Excelsior JET was a strong option for a long time on desktops up until 2018, main selling point was resistance to decompilation but not sure if they... - Source: Hacker News / over 3 years ago

  • Trying Bifrost: An AI Gateway That Simplified My Setup
    I wired it into OpenCode, an open-source coding harness similar to Claude Code and Codex. I'm using an OpenCode Zen key and a Gemini key, and together, these give me access to multiple SOTA models for free, without touching a separate dashboard for each provider. - Source: dev.to / 20 days ago

  • ZCode: Claude Code from the Makers of GLM
    Https://opencode.ai/ OpenCode was the first agent harness I used, and I have always like it. You can configure a wide variety of providers, but it's open source and has a number of core contributors. The other opinionated option is Pi (the Pi agent harness). This is a great lightweight option and also supports a number of providers. You can also use local model servers. - Source: Hacker News / about 2 months ago
