Free discussion & hackathon

• Created commiters group on GitHub.
• SMART pointers: which type of? (@dbatyai)
• Gepard: MovePtr<T, D = def>, UniqPtr<T, D = def>
• Own allocation system : usecases?
• Lots of small allocation, but freed in big chunks (Path)
• Big allocation (Images, Buffers)
  • Use nmap
• Stack like object lifecycle
• The vulkan drivers needs profiling
