"13 ways to run web applications on the Internet" Andrii ShumadaFwdays
1. There are 13 ways to launch an app to the internet including using a local machine with port forwarding, a local machine in an office with ngrok or localtunnel, a dedicated server with SFTP or SSH, cloud storage services, git-based static hosting, serverless technologies like AWS Lambda, and container/cluster-based options like Docker swarm, AWS EBS, and Kubernetes.
2. Each option has varying degrees of ease of setup, ease of deployment, scalability, and suitability for frontend versus backend apps. Local development options are easiest to setup but not production ready, while container/cluster options are more complex but very scalable and production ready.
3. The document provides a
The program uses a for loop to iterate from 1 to 100. Inside the loop, it uses if/else conditions to check if the number is divisible by 3, 5, or both and prints the corresponding string. If none of the conditions are met, it prints the number.
This document discusses Drupal's project management tools and resources for module maintainers, including automated testing, documentation, issue tracking, and community support. It highlights how some popular modules grew large developer communities that fixed over 90% of critical bugs through these resources. The document encourages contributors to write tests before committing code and review patches through the issue queue. It also lists projects needing maintenance help and provides contact information.
This document summarizes Phinx, a PHP database migration tool. It allows developers to programmatically update a database schema over time through migrations written in PHP. Key features include writing migrations, migrating up and down, seeding data, and supporting multiple databases like MySQL, PostgreSQL, and SQLite. The document provides installation instructions, best practices for writing migrations, and an overview of the tool's history and future plans.
This document demonstrates a continuous integration and delivery workflow using Concourse CI to deploy code changes through development, staging, and production environments on Cloud Foundry. It shows how features are developed on branches off of develop, merged to develop after testing, and later merged into release branches and deployed through the environments after additional testing before being promoted to production.
This document summarizes the use of Docker for a multisite Drupal development workflow. Key points include:
- Using Docker images and containers to share database layers between similar sites, improving build speeds.
- Implementing a "lazy" continuous integration workflow with a parent PR builder and child builders for specific sites/tasks, run in parallel.
- Introducing scripts to pull the latest database from production into a Docker image, then reusing that image for reinstalls rather than importing the full database each time.
- Describing how the Docker-based approach works on both the CI server and local developer environments.
- Noting some potential issues with Docker stability and leaving garbage,

This document provides guidelines and resources for setting up a Raspberry Pi development environment using Arch Linux ARM and Python. It includes links to documentation on installing and configuring the Raspberry Pi operating system, purchasing domain names and SSL certificates, using the Python Flask framework to build RESTful APIs with MongoDB and Redis, implementing Nginx, uWSGI, virtual environments, Markdown, HTML, CSS, security practices, and data visualization with Neo4j. Additional French language courses are referenced on using MongoDB, developing with Flask, learning Python, and working with HTML5 and CSS3.
The C++ compilation process involves pre-processing, compilation, assembly, and linking steps. Pre-processing expands macros, removes comments, and includes header files. Compilation performs syntax checking, error detection, and code optimization to generate assembly code. Assembly converts the assembly code into object files. Linking combines multiple object files and libraries into a single executable binary or ELF file.
This document discusses options for building static sites in Ruby. It outlines pros of using Jekyll, such as being well-known and having many plugins, but notes some missing features like asset precompilation and LiveReload. Alternatives to Jekyll are presented, including Middleman and using Sinatra for semi-static sites. The document concludes by thanking the audience.
The document discusses considerations for teaching Ruby on Rails. It notes that students come with a wide range of experience, from true beginners to veteran developers, and the content must be tailored accordingly. Managing student expectations is important, as the hype around Rails can raise expectations that are difficult to meet for beginners. Follow-through after initial lessons is also key to student retention, such as providing a roadmap for further learning.
Things IT Undergrads Should Know (But Don't)bryanbibat
This document provides advice for IT undergrads on things they should know but often don't. It emphasizes that the goal of an IT degree is to learn how to solve human problems using computers. It stresses that the most important language for undergrads to know is SQL. It also notes that employers hire programmers based on their problem-solving skills rather than specific languages. Undergrads should focus on learning fundamentals in college and exploring outside projects as soft skills and adaptability are crucial for success in the real world of constantly changing requirements and impossible deadlines.

Key places discussed include Egypt, the Negev desert, Hebron, and the Valley of Eshkol. The meanings of related words are explored. Uniting in love through Hebron is emphasized for experiencing the fruits of destiny like in Eshkol, though occupants like the Canaanites present opposition.
This document discusses theological topics related to the end times, including:
1. It proposes tentative timeframes for the return of Christ between 2017-2021 or 2021-2028 based on biblical patterns in the feasts of the Lord and 7-year cycles.
2. It addresses preliminary issues like prophetic imagination, the Sabbath versus Sunday, and warns against definite date setting.
3. For young people, it encourages sanctification, intimacy with God, developing bridal qualities, and helping to spiritually transform their region before Christ's return.
The overall document provides a framework for understanding the end times based on biblical patterns, while avoiding definite dates and emphasizing continued preparation.
Future of Ruby standard libraries will focus on gemification. Standard libraries will be extracted out of the Ruby core repository and maintained as default gems or bundled gems in GitHub repositories. This allows libraries to be updated independently of Ruby releases and more easily accept contributions. While this approach has benefits, it also has challenges around maintaining compatibility and complex dependencies. The process of gemification will be gradual to reduce the size of changes.

Sharing the whole journey experience. Starting with the handover of the keys of the pandora box, wandering around the deep dark forest of uncertainty and instability of the rushed deployed systems. Trying to declutter and reach a stable stage where the order reigns over chaos, where the poor guy can finally sleep at night and the pager eventually goes silent for a while. At the end we'll be reaching the so-desired level of confidence to not be worried about experimenting, changing things and upgrading infrastructure.
How to develop the Standard Libraries of Ruby?Hiroshi SHIBATA
I maintain the RubyGems, Bundler and the standard libraries of the Ruby language. So, I've been extract many of the standard libraries to default gems and GitHub at Ruby 3.0. But the some of libraries still remains in only Ruby repository. I will describe these situation.
RustPython is a project that implements the Python programming language in Rust. It started in May 2018 and released version 0.3 in September 2023. The standard library has been written in Rust and pip package management works. RustPython can compile to WebAssembly to run Python code in web browsers and has an experimental just-in-time compiler. Several popular Python packages were tested with varying results, with some packages like Django and others not working due to missing Python modules or compiler issues. Packaging Python modules that use Rust is becoming increasingly common using tools like PyO3, with over 50,000 downloads per day of related projects.

Similar to Upgrading to Ruby 2.1, Rails 4.0, Bootstrap 3.0 (20)
This document provides instructions on installing and using basic version control functionality with Git. It covers downloading and verifying Git installation, initializing and committing to a Git repository, viewing commit history and file status, staging and unstaging files, reverting and resetting commits, and tagging commits. The key points are initializing a Git repository, making commits to track changes over time, and various commands to move between commits, view history, and recover from mistakes.
The document provides an overview of the history and evolution of the Rails web framework from 2006 to 2013. It discusses how Rails initially aimed to make web development "easy" but this led to issues with code quality. It then outlines how conventions and best practices developed over time to structure Rails applications according to the MVC pattern and provide guidance on testing, deployment and other aspects of developing with Rails. The document also notes that many advanced Rails topics were not covered.
Things Future IT Students Should Know (But Don't)bryanbibat
The document discusses what future IT students should know about their field of study and career. It emphasizes that the goal of an IT degree is to learn how to solve human problems using computers. It stresses developing strong problem-solving, communication, and social skills which are more important than specific technical skills. Companies hire based on an individual's ability to solve problems rather than their particular degree. The document advises students to gain experience through projects, explore new technologies, and collaborate with others to prepare for an ever-changing career where adaptability is key.
From Novice to Expert: A Pragmatic Approach to Learningbryanbibat
From Novice to Expert discusses a pragmatic approach to learning based on the Dreyfus model of skill acquisition. The model describes five stages from novice to expert: novice, advanced beginner, competent, proficient, and expert. As individuals progress through these stages, their decision making shifts from relying solely on rules to developing intuition through experience. The document suggests applying this framework to understand the different needs of developers at various experience levels.
The document discusses Java 8 lambda expressions and how they can be used to filter, map, and reduce collections. It provides examples of filtering a list of employees to only those over age 60, mapping a list of employees to a list of their full names, and reducing a list of employees to calculate their total salary. It notes how lambda expressions allow bulk data operations on collections in a similar manner to SQL queries.
The document provides tips for preparing for a hackathon event called the WebGeek DevCup. It recommends preparing your application framework ahead of time by choosing technologies and setting up modules like authentication, but not completing the full application.
