The document discusses the past, present, and future of Cuis Smalltalk, emphasizing its community, ongoing projects, and efforts to reduce complexity in software development. Key issues highlighted include accidental complexity, code bloat, and the importance of understanding system design. Future plans include modularization, enhancing live-typing features, and improving the virtual machine while fostering a collaborative environment for users.
Cuis Smalltalk: Past, present and future by By Hernán Wilkinson & Juan Vuletich
- 1. Cuis Smalltalk Past, Present and What’s next Hernán A. Wilkinson - @hernanwilkinson 10Pines founder – Professor at UBA agile software development & services Juan Vuletich - @juanvuletich LabWare
- 2. Cuis Spirit Some typical problems of the software world ● A system you don't understand is a system you can't help evolve ● Accidental complexity makes it harder to understand ● Code bloat makes it impossible to understand! ● Just implementing what you need might mean not understanding the rest We can do better! ● A system can be as easy to understand as a well written book ● Accidental complexity can be kept to a minimum ● Code bloat can be avoided if you care ● Understanding where your work fits in a larger whole allows for consistency ● The system can help you understand
- 3. Not just technical but also human
- 4. Cuis Community ➔ Students per Semester: around 120 ◆ Got +10 contributions this semester, from refactorings to bug fixing ➔ Active List members: A few dozen ➔ Package Authors: Around 20, over 100 packages ➔ The rest of the Smalltalk Community: ◆ People developing VMs for Smalltalk test their work on Cuis ◆ People using other dialects share discussion, fixes and enhancements with Cuis ◆ People using tools/packages developed in Cuis ➔ The “Wise Elders”: Smalltalk creators and pioneers love Cuis! ➔ Total: We estimate around 200 people use Cuis on a regular basis
- 5. We want everyone to feel safe, to feel appreciated and have a good time with Cuis
- 7. New Refactorings (Thank you Nahuel Garbezza & Fernando Gasperi & students)
- 8. TDD Guru (Thank you Matias Dinota)
- 11. LiveTyping
- 12. CUIS CI (Thank you Gastón Caruso, Facu Gelatti, Nico Papagna & Ludat)
- 13. Other Research Projects ➔Generics for LiveTyping (Ana Felisatti & Mariano De Sousa) ➔Annotate closure types (Ines Sosa) ➔LiveTyping on JIT VM (Federico Grosso) ➔Type Checking improvements (Julian Luini) ➔Cuis OO Protector - COOP (Gaston Testay-Martin Gonzalez)
- 14. Vector Graphics Engine ● Both for Text and Graphics ● Unprecedented quality ● 100% Smalltalk ● High Performance OpenCL version will replace BitBlt ● Currently used for TrueType glyph rasterization
- 15. TrueType Fonts ● Entirely portable ● Doesn't use FreeType, host OS support or FFI ● 100% Smalltalk ● High quality (higher than FreeType, ClearType or Quartz) ● High performance ● Uses the Vector Graphics Engine
- 16. OpenCL ● OpenCL is the open standard alternative to CUDA ● Used for high performance computing on GPU and CPU ● OpenCL code embedded in Smalltalk code ● Immediate feedback, no external compile ● Used for satellite image processing & vector graphics engine
- 17. Alternative Graphics Backends ● Cairo (Mariano Montone) ○ https://github.com/Cuis-Smalltalk/Cairo ● OpenGL (Phil Bellalouna) ○ https://github.com/pbella/Cuis-OpenGL
- 18. What’s Next?
- 19. What’s next � Image modularization to be able to use GitHub as real source code repo �Changes model improvements �Make LiveTyping part of Cuis by default �More Refactorings! (Simple and Complex ones) �New VM with Boris JIT, Pocho’s PowerLand & LiveTyping ❓Compiler improvement based on LiveTyping to generate and initialize the PIC at compile time!! ❓Image Bootstraping
- 20. Conclusion
- 21. Conclusion ✌Cuis is a Smalltalk that it is fulfilling its purpose �It is a nice place to collaborate and learn �Ample room for improvement and tools re-thinking �It is an open and friendly community
- 23. Thanks!
