representation of the abstract entities in programming languages and the mapping of these onto machine languages within space and speed constraints.”Abstract “Most of the big gains in software productivity inordinately hard, such as severe hardware constraints, awkward programming languages, lack of machine time. How much of what software engineers now do is still devoted to the accidental, as opposed survives beyond the normal life of the machine for which it is first written • Software is embedded in a cultural matrix of applications, users, laws, and machine vehiclesInvisibility • Software is invisible

Rust-VMM? Rust-VMM is an open-source project that empowers the community to build custom Virtual Machine Monitors (VMMs) and hypervisors. It abstracts the common virtualization components which implements bindings to virtio kernel headers generated using bindgen. • vm-memory: abstractions over a virtual machine's memory. • vmm-sys-util: collection of modules providing helpers and utilities for building VMMs and hypervisors. Release Crates Cloud Hypervisor • Cloud Hypervisor is an open source Virtual Machine Monitor (VMM) that runs on top of KVM. • Implemented in Rust and is based on the Rust-VMM crates

Everyday Programming • constexpr has steadily increased in power • It's just code that runs on your machine instead of the user's • Example: lookup tables • Everyone uses lookup tables • Arrays are maximally associative • Avoids potential confusion41 Continuous Integration • Scripts prepare Azure Virtual Machine Scale Sets • Currently up to 12 VMs, each with 16 cores • VMs install VS (with Clang, CMake, Ninja)
