contexts can customize the implementation of standard algorithms for optimal performance. ● Key Features: ● Combining scheduler and policy. ● Minimal, incremental API changes.Combining Scheduler with and 4 are likely to make C++26. 2 and 3 will be beyond C++ 26. These are just some of the likely features that have progressed sufficiently and fit in a talk format, though they still may enter the standard

Leveraging C++20/23 Features for Low Level InteractionsOverview In a baremetal environment, we’re going to demonstrate e�ective use of C++ How did we end up with C language HW interactions? What are best e�ectively in line with C++ best practices? �. See also Stroustrup (2023), in referencesKey C++ Safety Features There’s lots, but…. Lifetime Management Smart pointers handle new/delete for you. We’ll mostly

less known webpack features in 15 minutes Goals Goals • Overview over less known features • Short • Learn something new • Code Samples Non-Goals • Detailed How-to-Use the features • Well formatted Bundle node.js applications • Use cases: Faster startup, loaders, custom resolving, all webpack features • But not all modules are compatible  externals • Also great: TODO node-modules externals // loads

more of your code than your poor overworked development team • Leverage c++’s many compile-time features to build rich, descriptive types • Thank you
