Explore and compare open source Ruby libraries
Linked is one of several comprehensive catalogs of Ruby tools, packages and libraries.
Build a Robot for Free!
The linked site has many very helpful and simple instructions and ideas for building your own robot. I just browsed and came across useful information even just the first time through
The easy-to-use getaway to historical maps in libraries around the world.
Linked is an amazing free tool. It lets you move a slider to shift the year that you are looking at. And then it shows a zoomable map and all sorts of historical info.
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.
A reactive notebook for Python — run reproducible experiments, execute as a script, deploy as an app, and version with git. - marimo-team/marimo: A reactive notebook for Python — run reproducible ...
An impressive "rewrite" of Jupyter Notebooks which has more logical "recalc" rules.
A very old blog
Linked is a very old article I came across about the early days of the NeXT computer and Lotusprov.
Random Nerd Tutorials helps makers, hobbyists and engineers build electronics projects. We make projects with: ESP32, ESP8266, Arduino, Raspberry Pi, Home Automation and Internet of Things. If you want to learn electronics and programming, you're in the right place.
I just came across the linked catalog of free tutorials. Looks like it could be very useful! Arduinos, Raspberry Pis, and more.
Attached is yet another article that tries to clarify the options for python package management. The problem is that this space is dynamic and overpopulated, so any article quickly becomes out of dare.
Learn Python typing (type hints) with interactive online
exercises!
Linked is a useful tool to level up on your python.
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 link is to a paper of mine that was/will be published as a chapter in this volume
👋🏼 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.
Like Heroku, but you own it.
Linked is an article about #dokku which is software that lets you run the equivalent (more or less) of #heroku on your own server, including a server instance from a service like #digitalocean. Very nice. Good offering to remember!dokku
I've hired a lot of developers over the years. More than a few of them have come in with a strong...
Linked is a quite insightful article about good vs bad refactoring. What? Isn’t refactoring always “good”? There are lots of examples of bad ones here.
A LaTeX CV/Resume Framework. Contribute to sinaatalay/rendercv development by creating an account on GitHub.
Kinda cool. Linked is a simple tool which formats a cv in one of several styles. But the trick is that the input is a yaml file which contains all the content as a structured text file that you can edit with vscode and version track with GitHub. Nice!
Easily document cables and wiring harnesses. Contribute to wireviz/WireViz development by creating an account on GitHub.
For you hardware hackers and builders out there.. linked is a very cool tool to docutment wiring in your robots and other devices as well as generate pretty pictures and even a BOM!
Learn web development with Python and the Django Web Framework. Tutorials on Django REST Framework, Docker, React, and Vue.
Linked is a good review of Python Flask and Django. I came from a Ruby world, that’s like comparing Sinatra to Rails. Very different and very related.
Richard Feynman
I think Richard Feynman coined the term “cargo cult” in the 70’s! More important is his description of the scientific process, and his high standard and description of integrity in doing science. Computer Scientists, does your research achieve Feynman’s standard?
Learn about hash value omission in Ruby, their benefits, examples, and implementation guidelines for more concise code
Linked is an article about a feature in Ruby that I didn’t know about. I still think Ruby is superior to python in many ways. Unfortunately circumstances and “the world” and “time” has gotten me leaning more and more into python. Still when I next need to create a web based app, I can’t see using…
Amazing ai generated videos
Linked is a service that generates quite respectable short promotional videos. I tried it on the syllabus to my course and it created something fairly amazing. I mean it’s still obviously ai generated. After your amazement subsides you may still not want to use it but it’s worth checking out.…
A CLI utility and Python library for interacting with Large Language Models, both via remote APIs and models that can be installed and run on your own machine.
Follow the link below: I’ve been looking for a nicely packaged way to try llms locally, that is without using a cloud based service and without uploading my pi to another company. This tool is a good solution to the problem.
