That is why it can be considered as a language of space, as it can encode any existent mathematics.\n\nSpeaker: Maxim Sokhatsky is an author of Privat24 deposits, 20 years of working experience as a programmer, one of the 30 top-commiters in Ukraine in Open Source, author of N2O, the best Erlang Web Framework, CEO of Synrc Research Center, author of several embedded operating system runtimes and production programming languages. Maxim is familiar with any programming language on the planet and had seen sources of all operating systems.\n\nNow Maxim is doing his Ph.D. research (the second year of education) in HoTT, trying to encode as much mathematics in the programming language as possible along the way.\n\nDuring this lecture, Maxim will try to smoothly guide you from the programming perspective to the pure space of mathematics and will show the evolution of mathematical provers from AUTOMATH to the family of Cubical Type Checkers. Also, this lecture is considered as a general introduction to HoTT course Maxim is preparing for his friends.\n\nCredits\n-------\n\n* Intetics (http://intetics.com) Sponsor\n* HoTT Courses (https://anders.groupoid.space/lib/)\n\n# The Languages #2\n\nGroupoid Infinity Presentation (Slides) for Public Event Quanterall HQ Varna, Bulgaria, 13 June 2019\u003cbr\u003e\nDOI: 10.13140/RG.2.2.28584.21763 \u003ca href=\"https://cafe.groupoid.space/languages.pdf\"\u003ecafe.groupoid.space/languages.pdf\u003c/a\u003e\n\nAbstract\n--------\n\nIntroduction to Formal Languages, its Design and Implementations.\nThree practial modern pure languages will be disclosed: Plutus (Haskell), Morte (Erlang), Formality (Rust).\n\n# The Systems #3\n\nVoxoz Presentation (Slides) for Public Event Quanterall HQ Varna, Bulgaria, 27 June 2019\u003cbr\u003e\nDOI: 10.13140/RG.2.2.28584.21763 \u003ca href=\"https://cafe.groupoid.space/systems.pdf\"\u003ecafe.groupoid.space/systems.pdf\u003c/a\u003e\n\nAbstract\n--------\n\nIntroduction to Operating Systems, its Design and Implementations.\nPOSIX, Microkernels, Unikernels.\nReal time unikernel with O vector processing language will be disclosed.\n\nCredits\n-------\n\n* Quanterall (http://quanterall.com) Sponsor\n\n# Anders 0.7.2 #4\n\nPublic Event, Kyiv, Ukraine, Groupoid Cafe, 17 July 2021\u003cbr\u003e\nDOI: 10.13140/RG.2.2.25096.55040 \u003ca href=\"https://cafe.groupoid.space/anders.0.7.2.pdf\"\u003ecafe.groupoid.space/anders.0.7.2.pdf\u003c/a\u003e\n\nAbstract\n--------\n\nThe HTS language proposed by Voevodsky exposes two different presheaf\nmodels of type theory: the inner one is homotopy type system presheaf\nthat models HoTT and the outer one is traditional Martin-Löf type system presheaf\nthat models set theory with UIP. The motivation behind this doubling\nis to have an ability to express semisemplicial types. Theoretical\nwork on merging inner and outer languages was continued in 2LTT.\n\nWhile we are on our road to Lean-like tactic language, currently\nwe are at the stage of regular cubical HTS type checker with CHM-style\nprimitives.
