love 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 and safety, especially safe concurrency. empty • vmm-vcpu: a hypervisor-agnostic abstraction for Virtual CPUs (vCPUs). rust-vmm • event-manager: abstractions for implementing event based systems. • linux-loader: 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

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

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

(*func)(int x); 则对他的调用 (*func)(42); 会得到： • mov edi, 42 • call [func] 热知识： C++ 的虚函数就是函数指针 • 通过 virtual 关键字给类定义一个虚函数，他其实就是在类成员里加了一个函数指针。 • 而在构造函数里，会把当前类重载过的虚函数，赋予给那个函数指针，实现多态。 • 虚函数是 C++ 的语法糖，纯 C 的 Linux
