Installing Ubuntu from a USB memory stick This guide will help you install Ubuntu on your computer by using a USB memory stick. USB memory sticks are sometimes known as flash drives, memory pens or USB Mass Storage Storage devices. Installing from a memory stick is useful if you have a computer without a CD drive (like a netbook), or prefer the convenience of a memory stick. Alternative methods are available, like running Windows. ### 1. What do I need to get started? To install Ubuntu from a USB memory stick you need: - A memory stick with a capacity of at least 2GB. It will be formatted (erased) during this process

## A Relaxed Guide to memory_order_relaxed Hans Boehm Paul E. McKenney Google Facebook CPPCON 2020 ## std::atomic/std::atomic_ref and memory_order_relaxed - C++ atomic operations are sequentially consistent sacrificing the simple threads-as-interleaving semantics - by passing memory order enum values to explicit atomic operations. - In particular, memory_order_relaxed allows arbitrary visibility reordering with respect respect to accesses to other locations. ## What is Not to Like About memory order relaxed? - Just a load, just a store: Full control, excellent efficiency and scalability! ☐ Assuming aligned machine-sized

Practical memory pool based allocators for Modern C++ ## PREVIOUSLY ON cppcon • CppCon 2019: Safe Software for Autonomous Mobility With Modern C++ by Andreas Pasternak • Quote: “Memory pools and allocators piece in (more) depth ## Memory allocations in real-time safety-critical environment • The solution should be safe and certifiable • What does it mean practically for C++ memory allocations? We asked Autosar C++ 14 Coding Guidelines regarding memory allocations” ## Autosar C++ guidelines Rule A18-5-5 (required, implementation, partially automated) Memory management functions shall ensure the following:
