Python tools for data visualization — PyViz 0.0.1 documentation

Source: pyviz.org

Welcome to PyViz! The PyViz.org website is an open platform for helping users decide on the best open-source (OSS) Python data visualization tools for their purposes, with links, overviews, comparisons, and examples.

Linked is a big ole catalog of all the different visualization tools, packages and frameworks in python. Handy resource if you are experiencing analysis paralysis!

Music programming in the browser

Linked is a tool for writing electronic sounding music 5hrough a cryptic language, right in the browser. It reminds me of SonicPi except with a far worse syntax. But it runs in the browser which is pretty cool!

👻 Ghostty is a fast, feature-rich, and cross-platform terminal emulator that uses platform-native UI and GPU acceleration. - ghostty-org/ghostty

Linked is a new terminal emulator. What interests me is that it is said to be embeddable because it is distributed also as a library with well defined apis.

A fast and efficient type assistant for Python, including tensor shape inference - RightTyper/RightTyper

Linked is Python RIghtTyper which sounds great... if it works. It will analyze the type hints in your python (if any) and offers to gerentate them for you. Something like that. Many ways in which that might not go right but I read a very positive overview of it!

How to Calculate the Motor Torque for a Mobile Robot

How to Calculate the Motor Torque for a Mobile Robot

Source: wiki.dfrobot.com

This guide outlines how to calculate power parameters for a mobile robot and select an appropriate power system. We cover frictional and acceleration forces, wheel type, and motor parameters to design a direct-drive system with a brushless motor. With the rated voltage, speed, and torque of the motor, we calculate the required power and minimum battery capacity to power the robot successfully. This discussion is a valuable resource for designing or selecting a power system for an indoor, service-oriented mobile robot capable of carrying a payload of 20 kg and achieving a speed of 1.

Linked is an article explaining how to calculate torque. But why? When choosing a motor for a robot, you need to calculate the torque required, which in turn depends on the weight of the robot, the diameter of the wheels, and other parameters.

An impressive "rewrite" of Jupyter Notebooks which has more logical "recalc" rules.

Seven years ago (2016), we began integrating Robotics into our Computer Science curriculum. This paper explores the mission, initial goals and objectives, specific choices we made along the way, and why and outcomes. Of course, we were not the first to do so. Our...

The Thread API : Concurrent, colorless Ruby

The Thread API : Concurrent, colorless Ruby

👋🏼 This is part of series on concurrency, parallelism and asynchronous programming in Ruby. It’s a deep dive, so it’s divided into 12 main parts:
Your Ruby programs are always multi-threaded: Part 1 Your Ruby programs are always multi-threaded: Part 2 Consistent, request-local state Ruby methods are colorless The Thread API: Concurrent, colorless Ruby Interrupting Threads: Concurrent, colorless Ruby Thread and its MaNy friends: Concurrent, colorless Ruby Fibers: Concurrent, colorless Ruby Processes, Ractors and alternative runtimes: Parallel Ruby Scaling concurrency: Streaming Ruby Abstracted, concurrent Ruby Closing thoughts, kicking the tires and tangents How I dive into CRuby concurrency You’re reading “The Thread API: Concurrent, colorless Ruby”.

Linked is a really excellent, comprehensive tour of the Thread class and feature of Ruby. If you're a ruby person, then this is as good as anything you will find.
