Summary

Stormy Peters talks about open source software and how to support the communities that create it.

Details

Who she is, what she does. What open source software is, what free means. Different types of OSS licenses, beerware, restrictive licenses. Commercial use of open software. Making OSS financially viable; tools that GitHub offers, most software is built on open source software. "We're not paying for free software!", normalizing paying for OSS; hard for companies to make payments; GitHub sponsors for companies. Individuals sponsoring/supporting OSS, getting in touch with maintainers. Barriers to getting involved. One-person projects. Sponsorship by programming language. Is anyone making enough money from sponsorship. How GitHub supports OSS developers; corporate sponsors. Copilot and its use of OSS. Future of OSS. How to get involved in OSS.

Summary

Andy Gocke, lead of the native AOT and app model team at Microsoft talks about ahead-of-time compilation (AOT) in .NET.

Details

Who he is, what he does. Quick overview of ahead-of-time compilation (AOT); finding your code. Traditional compilation, interpreter vs compiler, translation from source to target languages. Operating systems, intermediate language (IL). There's always an interpreter. Just-in-time compilation (JIT); Java ran on multiple OSes, but .NET was Windows only; .NET ran on multiple architectures. Ready-to-run (R2R) and trimming. Tiered compilation, variable performance. R2R mixes precompiled and IL, native AOT only has precompiled. Trimming - getting rid of unneeded things, trouble with plugins and reflection; static analysis - don't ignore warnings. Why AOT was built, where it is a good fit. How much work it was; Core RT, low adoption, but good feedback. Good and bad use cases for AOT. For .NET 7 console apps and libraries, or if you don't get trim warnings; a single trim warning is too many. AOT and non-AOT OSS NuGet packages. .NET 8 support for ASP.NET. JIT and IL will not go away. AWS Lambda functions and AOT, exclusions, problems that might occur; trimmable all the way down. Getting started with AOT. Can't turn off trimming. Future of AOT.
