Roadmap
• Private
• Accounting
• Other languages (Python, Node, Fortran)
– “Its kind of loony tunes that PyPI, RubyGems, CPAN,
NPM are all separate systems” A. Gaynor (yesterday)
• RaspberryPI
• Other languages integration(python + c)
• Challenges:
– Scalability, robustness, security
www.biicode.com Nov-13
Community Beta
• YES:
– Zlib, box2d, little_cms, crypto, freeglut, eigen, csparse, gtest, gmock
• NO:
– Boost (binary ongoing, git?)
– OpenCV (src ongoing)
– WxWidgets (binary experimental, src ongoing)
• FEW:
– Docs, tutorials
– Google help
– Usability
• EXPERIMENTAL:
– Merge
– Git
