Rails Girls Guides
The purpose of Rails Girls is to give tools for women to understand technology. The Rails Girls events do this by providing a great first experience on building the Internet.
Rails Girls was founded at the end of 2010 in Helsinki. Originally intended as a one-time event, we never thought to see so many chapters from all around the world! This guide will help you get started.
You can use our materials and instructions to roll out your own workshop in your city, workplace or kitchen! Read more about Rails Girls at http://railsgirls.com
railsbridge/docs
The RailsBridge Documentation Project
Overview
This is a Sinatra app, deployed at http://docs.railsbridge.org. The RailsBridge documentation project is home to a few subprojects, including the RailsBridge installfest instructions, which leads students through the various complicated setup instructions for getting Ruby, Rails, Git, etc. installed on their computer (whatever combination of computer, OS, and version they happened to bring to the workshop!), as well as the RailsBridge workshop “Suggestotron” curriculum.
Each subproject (a “site”) comprises files stored under the “sites” directory; for instance, the installfest instructions are located at ROOT/sites/en/installfest, while the intro rails curriculum can be found under ROOT/sites/en/intro-to-rails. (The “en” means “English” — see “Locales” below.)
freeCodeCamp/freeCodeCamp

kamranahmedse/developer-roadmap
Purpose of these Roadmaps
The purpose of these roadmaps is to give you an idea about the landscape and to guide you if you are confused about what to learn next and not to encourage you to pick what is hip and trendy. You should grow some understanding of why one tool would be better suited for some cases than the other and remember hip and trendy never means best suited for the job.
Note to Beginners
These roadmaps cover everything that is there to learn for the paths listed below. Don’t feel overwhelmed, you don’t need to learn it all in the beginning if you are just getting started. We are working on the beginner versions of these and will release it soon after we are done with the 2021 release of the Backend and DevOps roadmaps.
If you think that these can be improved in any way, please do suggest.

Fluency on the command line is a skill often neglected or considered arcane, but it improves your flexibility and productivity as an engineer in both obvious and subtle ways. This is a selection of notes and tips on using the command-line that we’ve found useful when working on Linux. Some tips are elementary, and some are fairly specific, sophisticated, or obscure. This page is not long, but if you can use and recall all the items here, you know a lot.
This work is the result of many authors and translators. Some of this originally appeared on Quora, but it has since moved to GitHub, where people more talented than the original author have made numerous improvements. Please submit a question if you have a question related to the command line. Please contribute if you see an error or something that could be better!
papers-we-love/papers-we-love
Papers We Love (PWL) is a community built around reading, discussing and learning more about academic computer science papers. This repository serves as a directory of some of the best papers the community can find, bringing together documents scattered across the web. You can also visit the Papers We Love site for more info.
Due to licenses we cannot always host the papers themselves (when we do, you will see a 📜 emoji next to its title in the directory README) but we can provide links to their locations.
If you enjoy the papers, perhaps stop by a local chapter meetup and join in on the vibrant discussions around them. You can also discuss PWL events, the content in this repository, and/or anything related to PWL on our Slack, after signing-up to join it, or on our #paperswelove IRC channel on freenode.

ripienaar/free-for-dev

Developers and Open Source authors now have a massive amount of services offering free tiers, but it can be hard to find them all to make informed decisions.
This is a list of software (SaaS, PaaS, IaaS, etc.) and other offerings that have free tiers for developers.
The scope of this particular list is limited to things that infrastructure developers (System Administrator, DevOps Practitioners, etc.) are likely to find useful. We love all the free services out there, but it would be good to keep it on topic. It’s a bit of a grey line at times so this is a bit opinionated; do not be offended if I do not accept your contribution.
This list is the result of Pull Requests, reviews, ideas and work done by 900+ people. You too can help by sending Pull Requests to add more services or by remove ones whose offerings have changed or been retired.
NOTE: This list is only for as-a-Service offerings, not for self-hosted software. For a service to be eligible it has to offer a free tier and not just a free trial. If the free tier is time-bucketed it has to be for at least a year. We also consider the free tier from a security perspective, so SSO is fine but I will not accept services that restrict TLS to paid-only tiers.
gothinkster/realworld
Stay on the bleeding edge — join our GitHub Discussions! 🎉
See how the exact same Medium.com clone (called Conduit) is built using different frontends and backends. Yes, you can mix and match them, because they all adhere to the same API spec 😮😎
While most “todo” demos provide an excellent cursory glance at a framework’s capabilities, they typically don’t convey the knowledge & perspective required to actually build real applications with it.
RealWorld solves this by allowing you to choose any frontend (React, Angular 2, & more) and any backend (Node, Django, & more) and see how they power a real world, beautifully designed fullstack app called “Conduit”.
Read the full blog post announcing RealWorld on Medium.
Implementations
Over 100 implementations have been created using various languages, libraries, and frameworks.
See the list of implementations on the CodebaseShow website >>>
Create a new implementation
Create a new implementation >>>
Or you can view upcoming implementations (WIPs).
How do I get up & running?
Follow the instructions in the README of whatever frontend and/or backend repo’s you want to get up and running.
Can you teach me how to build each stack from scratch?
Yup! We’ve built step-by-step tutorials for all of our stacks
that teach you how to go from
git init all
the way to the production ready application.

Front-End Checklist
The Front-End Checklist is an exhaustive list of all elements you need to have / to test before launching your website / HTML page to production.
How To Use • Contributing • Website • Product Hunt
Other Checklists:
🎮 Front-End Performance Checklist
•
💎 Front-End Design Checklist
It is based on Front-End developers’ years of experience, with the additions coming from some other open-source checklists.
How to use?
All items in the Front-End Checklist are required for the majority of the projects, but some elements can be omitted or are not essential (in the case of an administration web app, you may not need RSS feed for example). We choose to use 3 levels of flexibility:
- means that the item is recommended but can be omitted in some particular situations.
- means that the item is highly recommended and can eventually be omitted in some really particular cases. Some elements, if omitted, can have bad repercussions in terms of performance or SEO.
- means that the item can’t be omitted by any reason. You may cause a dysfunction in your page or have accessibility or SEO issues. The testing priority needs to be on these elements first.
Some resources possess an emoticon to help you understand which type of content / help you may find on the checklist:
- 📖: documentation or article
- 🛠: online tool / testing tool
- 📹: media or video content
You can contribute to the Front-End Checklist App reading the CONTRIBUTING.md file which explains everything about the project.
