Visualizing Algorithms

The power of the unaided mind is highly overrated… The real powers come from devising external aids that enhance cognitive abilities. —Donald Norman Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. Instead there are logical rules that describe behavior. This may be why algorithm visualizations are so unusual, as designers experiment with novel forms to better communicate. But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. #Sampling Before I can explain the first algorithm, I first need to explain the problem it addresses. Light — electromagnetic radiation — the light emanating from this screen, traveling through the air, focused by your lens and projected onto the retina — is a continuous signal. This reduction process is called sampling, and it is essential to vision. Sampling is made difficult by competing goals. Here’s how it works:

Install Rust - Rust Programming Language Getting started If you're just getting started with Rust and would like a more detailed walk-through, see our getting started page. Windows considerations On Windows, Rust additionally requires the C++ build tools for Visual Studio 2013 or later. The easiest way to acquire the build tools is by installing Microsoft Visual C++ Build Tools 2019 which provides just the Visual C++ build tools.

Other Installation Methods · The Rust Programming Language Which installer should you use? Rust runs on many platforms, and there are many ways to install Rust. If you want to install Rust in the most straightforward, recommended way, then follow the instructions on the main installation page. That page describes installation via rustup, a tool that manages multiple Rust toolchains in a consistent way across all platforms Rust supports. Why might one not want to install using those instructions?

Searching Algorithms ‘Recent Articles’ on Searching Searching Algorithms are designed to check for an element or retrieve an element from any data structure where it is stored. Based on the type of search operation, these algorithms are generally classified into two categories: Population count Population count You are encouraged to solve this task according to the task description, using any language you may know. The population count is the number of 1s (ones) in the binary representation of a non-negative integer. Population count is also known as pop count, popcount, sideways sum, and Hamming weight. Library Documentation Accumulators Framework for incremental calculation, and collection of statistical accumulators. Author(s)

Software optimization resources. C++ and assembly. Windows, Linux, BSD, Mac OS X See also my blog Contents Optimization manuals This series of five manuals describes everything you need to know about optimizing code for x86 and x86-64 family microprocessors, including optimization advices for C++ and assembly language, details about the microarchitecture and instruction timings of most Intel, AMD and VIA processors, and details about different compilers and calling conventions. Operating systems covered: DOS, Windows, Linux, BSD, Mac OS X Intel based, 32 and 64 bits. Note that these manuals are not for beginners. Using classes exported from a DLL using LoadLibrary Introduction I have seen quite a lot of code explaining how to use classes exported from a DLL in an application. However, all these describe the usage of the exported classes by linking implicitly to the DLL.
