Behind the elegant facade of LINQ lies a meticulously engineered core designed for more than just simplicity. This article delves into the technical intricacies of LINQ, focusing on the “speed optimizations” that enhance its execution efficiency. These optimizations also have many shortcomings. LINQ LINQ is short for “Language Integrated Query”. It’s…

EDIT: Added “Return items by reference” section In the dynamic landscape of modern software development, efficient data processing lies at the core of creating high-performance applications. As developers, we constantly strive to balance readability, maintainability, and speed when writing code. …

Introduction ImmutableArray<T> is one of the collections provided in the System.Collections.Immutable namespace. All collections in this namespace are immutable, meaning that they cannot be altered once created. These collections do provide mutation methods like Add(), AddRange(), Remove(), RemoveAll(), and so on. The thing is, for these collections, all these methods output…

I’ve been writing articles about performance in .NET for several years but I frequently find in the comments the famous quote from the paper “Structured Programming with go to Statements” by Donald Knuth: We should forget about small efficiencies, say about 97% of the time: premature optimization is the root…

What is SIMD? SIMD stands for “Single Instruction, Multiple Data”. It is a type of parallel processing technique that allows a single instruction to be executed on multiple data elements simultaneously. SIMD enables efficient and high-performance execution of repetitive operations on large sets of data, such as vector and matrix computations. In SIMD…

Before .NET 7 Some .NET languages like C# support the definition of arithmetic operators. These can be used to write math expressions using the familiar arithmetic operators (+, -, *, /) instead of calling methods (Add, Subtract, Multiply, Divide). For math operations that are not expressed as operators, like trigonometric operations, .NET provides…

NOTE: This series of articles use TypeChain to make strongly-typed calls to Ethereum. Please check its documentation and discussion board to learn how to set it up. It’s also assumed some knowledge of React Query. In my previous post I created a custom hook that wraps the following code: …

In previous posts I explained how React Query can be used to query smart contracts, that is, to perform read calls. Now I’m going to explain how to mutate, that is, to execute transactions on the blockchain. Unlike read calls, execution of transactions requires the confirmation by the user on…

Wallets that support multiple accounts and multiple blockchains, like MetaMask, make it very easy for a user to change active account and active blockchain. A web3 frontend should react immediately to these changes. NOTE: This series of articles use TypeChain to make strongly-typed calls to Ethereum. Please check its documentation…
