Insert the README into a crate’s documentation by putting #![doc = include_str!("../README.md")] in lib.rs. This can help avoid duplicating information between the README and the documentation, and will also test README examples as doctests.

If you have a reference to some data and you want to pass it to a function that takes a slice, you can use std::array::from_ref to cheaply create a slice without copying.

How much power can you derive from a good type system? Let's use Rust to illustrate a concept I never once heard in college, but has been invaluable to me throughout my software development career: "Make invalid states unrepresentable." You may have seen this statement on Haskell forums, etc. but if you're not familiar with Haskell or other languages with similarly expressive type systems, it might not seem feasible to encode much or complex structure into your types. This video is a short discussion and overview of some of the ideas underlying that mantra. I hope you find it useful!

Former President of the United States of America, Donald J. Trump, has officially released a collection of NFT collectibles called "Trump Digital Trading Cards."

The keywords memory, storage, calldata are a big pain point for new Solidity developers, but they don't have to be! We explore storage locations in-depth in the Ethereum ecosystem, as well as compare to NEAR Protocol. Read the accompanying blog post: https://medium.com/geeklaunch/storage-locations-in-ethereum-vs-near-9ce5e2f0b79 Test contract code (Remix): https://remix.ethereum.org/?gist=ac0bce6c2c3c59ab979de2b179ae1e55 Test contract code (GitHub Gist): https://gist.github.com/encody/ac0bce6c2c3c59ab979de2b179ae1e55 Learn more about NEAR Protocol: https://near.org Full disclosure, I have done contract work for NEAR Protocol in the past, which is one of the reasons I'm especially familiar with the protocol. In the interest of being fully transparent, I also checked the "contains paid promotion" box.

There's more than one issue with the newly minted Miss Universe NFT project. We'll check out an issue with the dapp and the metadata/smart contract. I did make sure I contacted their support about this issue before even recording this video, but I never got a response. Note that the ETH address show in my MetaMask in this video is just a throwaway.
