10:25	*DJSON + Phoscript = OmniWeb** - Liang Ng “DJSON - Decentralised JSON - is a simple but powerful extension of JSON, where one or more fields of a JSON are encoded as hash strings, thus providing properties of ownerships of digital assets similar to Bitcoin address, without requiring cumbersome implementations of Blockchain infrastructure. Combining DJSON with Phoscript, a Forth dialect that is easily portable to any host programming language, they form a homoiconic universal solution, capable of integrating systems written in different programming languages, and exchanging data in different formats, hence the name OmniWeb.” Video (34:30) Slides OmniWeb + Omni*DOC
10:59	Metaprogramming VAMP in KYRA, A Next-gen Forth-like Language - Onat Türkçüoglu A fresh language and philosophy for coding CPUs / GPUs from scratch will be presented along with many inventions, design decisions, tradeoffs, and hurdles. Topics include discussing the essence of Forth, questioning the current understanding of it , and visions about the future of software and hardware. VAMP is an interactive tiling video player using Vulkan, SDL, and FFMPEG, all including SPIR-V shaders coded in KYRA from scratch. Video (1:57:07) Teaser video from February (7:30)
