The document discusses habits and how to change them. It mentions the book "The Power of Habit" by Charles Duhigg and provides a summary of its key points. It also lists apps and websites for tracking health and fitness habits like walking and diet. The document promotes forming regular habits and incrementally increasing goals over time through step-by-step progression.
Performance Comparison of Mutex, RWLock and Atomic types in RustMitsunori Komatsu
This document compares the performance of Mutex, RWLock, and atomic types for concurrent access in Rust. It presents benchmark results from a Rust program that tests updating a shared variable with these different synchronization methods under varying read/write loads on Linux and macOS. The results show that RWLock performance degrades significantly with more writes, Mutex performance is consistent even with writes, and atomic types are always the fastest for a counter.
The document introduces the Guzzle HTTP client library for PHP, covering its main features and providing examples of basic usage. It discusses Guzzle's asynchronous capabilities using Guzzle Promises and how to test requests using a MockHandler. The handler is highlighted as central to Guzzle's functionality, with examples given of different handler types that can be passed to the client. Contributing to Guzzle's large codebase is encouraged.
1. PyData is a community for users and developers of open-source data tools in Python including NumPy, Pandas, SciPy, scikit-learn, IPython, and Jupyter.
2. Pandas is a software library written for data manipulation and analysis in Python, built on top of NumPy and SciPy. It provides data structures and operations for working with relational or labeled data and time series.
3. Jupyter Notebook is an open-source web application that allows users to create and share documents that contain live code, equations, visualizations and explanatory text. It supports over 40 programming languages including Python, R and Julia.
