A rendering engine draws images of the application to the screen by using vertex and index buffers. The models used in games are created out of triangles, which the rendering engine uses to draw. A vertex buffer is a list of coordinates used for drawing triangles. The index buffer helps save memory by reducing the need to store shared vertices in the vertex buffer.
You can improve your mood, your sleep, and reduce your stress and anxiety by this one simple trick: exercise! As an engineer in front of a computer all day, it can be hard to get exercise. But if you start with imagining yourself exercising, before you know it you will be out the door. Where you are now started at some point with your imagination and now here you are. You could start with a five minute walk. Go outside and enjoy the clouds for a few minutes. Small wins add up and eventually your five minute walk will turn into more.
One of the coolest parts of Solidity is you can create functions that control and manipulate the ether cryptocurrency. When you mark a function as payable, it means the function can receive the ether cryptocurrency. Code itself can control value, with any owner that we want to specify with our imagination. Additionally, certain aspects of time can be relied upon without having to trust any single entity, only the network itself. In this example, we will create a contract that locks the ether given to it for a certain amount of time. Once the time has elapsed, the owner can get the ether back out. This is just a start to get you familiar with the syntax, but with your creativity and imagination you could make something much cooler.
Today begins your adventures with Solidity, the smart contract programming language invented for the Ethereum blockchain. Solidity allows your to harness the power of a global shared computer. Anyone can add programs and call functions on this computer. You can upload anything you want to this computer and nobody is going to stop you as long as you follow the rules of the network. Ethereum’s website says the network “allows you to build applications that run exactly as programmed without any possibility of downtime, censorship, fraud, or third-party interference.” Lets get started!
Today you will learn the basics of what a stack and a queue are. Stacks and queues are ordered lists of things. They could be strings, numbers, or anything else you can think of. Stacks and queues each have a unique way of adding and removing elements from their data structure. In a stack, you push elements when you add them and pop elements when you remove them. In a queue, you enqueue elements when you add them and dequeue elements when you remove them.
