Continuous integration for Ruby on Rails
Continuous integration for Ruby on RailsDavid Paluy Continuous integration (CI) is a development practice that requires developers to integrate code into a shared repository multiple times per day. Each check-in is automatically built and tested to find problems early. For Ruby on Rails projects, CI can generate code coverage reports, perform static code analysis, and document APIs. CI builds confidence by continuously integrating and testing code changes. Continuous deployment further automates software delivery through continuous integration.
Tdd - Test Driven Development
Tdd - Test Driven DevelopmentDavid Paluy TDD involves writing tests before writing code to ensure code works as intended and allows for refactoring. The TDD process involves writing specifications, tests, and then code. Tests provide confidence that code works, help design better code, and act as documentation. Tests should be written even for code that currently works perfectly since requirements and needs change over time. The benefits of TDD include producing modular code that is easy to change and refactor.

Tools to help you understand other people's codeDavid Paluy The document discusses tools and strategies for understanding and improving code, particularly when collaborating with others. Key topics include class diagrams, outdated gems, and the importance of testing before refactoring. It emphasizes that great programmers prioritize writing readable code for humans over code that is simply functional for machines.
Debugging and Profiling Rails Application
Debugging and Profiling Rails ApplicationDavid Paluy The document discusses debugging and profiling a Ruby on Rails application that is using excessive memory. It explains how the Ruby garbage collector works and that allocating too many objects can lead to longer garbage collection times and eventually running out of memory. Various tools are presented for debugging memory issues, including pry-debugger, ObjectSpace.count_objects, enabling heap dumps, and gdb.rb. Profiling tools discussed include Benchmark, ruby-prof, and perftools.rb for measuring time, allocations, memory usage, and garbage collection metrics. The key message is that allocating too many objects leads to slowdowns from longer garbage collection, so examining the heap and using debugging and profiling tools is important.
Security on Rails
Security on RailsDavid Paluy This document discusses various security vulnerabilities in Ruby on Rails applications including session hijacking, CSRF, mass assignment, and SQL injection. It provides recommendations to address these issues such as using SSL, adding session expiration, sanitizing user input, and using parameterized queries. The key takeaway is that security must be an ongoing process as new vulnerabilities emerge, and failing to address issues can enable catastrophic attacks on applications and user data.

Howto prepare fund raising presentation
Howto prepare fund raising presentationDavid Paluy The document provides tips for maintaining hard drives, including defining a goal, telling your story to convey lessons learned, performing daily maintenance such as spinning down and up and scanning data, ensuring critical data redundancy, staying cool, and allowing idle time. It emphasizes there is no second chance to make a good first impression when it comes to hard drive maintenance.
Test driven-development
Test driven-developmentDavid Paluy The document discusses test-driven development (TDD) and its benefits. It explains that TDD involves writing tests before code to ensure code is focused, clear, and passes all tests. TDD follows a process of red-green-refactor where tests are written, then code is written to pass failing tests, and code is optimized. Well-written tests also serve as documentation and examples of how code should work. The document advocates for TDD, as it breeds confidence through testing, helps write better code, and provides documentation without comments. An example demonstrates writing tests for a credit card submission process before coding the functionality.

The Anxious Generation Summary: How Digital Upheaval Is Damaging Youth Mental...MohammedTouzani2 The Anxious Generation Summary & Review
What Is The Anxious Generation About?
The Anxious Generation explores how rapid digital transformation has profoundly impacted children's development, leading to a surge in anxiety, depression, and other mental health issues. In his compelling new work, Jonathan Haidt, a social psychologist at NYU, argues that smartphones and social media are the primary culprits in what he calls "The Great Rewiring of Childhood."
By dissecting recent behavioral trends, neuroscience research, and social dynamics, Haidt reveals a generation overwhelmed by connectivity and stripped of physical, emotional, and spiritual development. If you’re a parent, educator, policymaker, or concerned citizen, this book provides the answers you need to understand — and counter — this crisis.

Rewire Your Day: 10 Everyday Biohacks for Energy, Clarity, and Empowerment
Rewire Your Day: 10 Everyday Biohacks for Energy, Clarity, and Empowermentcathassistservice What if feeling better—more focused, energized, or calm—didn’t require a major lifestyle change… just a few small tweaks?
That’s the power of biohacking.
It’s not about doing extreme things or chasing perfection.
It’s about making small, intentional shifts to your habits, environment, and mindset so your biology supports you—not the other way around.
Tired in the afternoon? Try water and light movement instead of another coffee.
Trouble sleeping? Cut screens an hour before bed and dim the lights.
Constantly stressed? A few deep breaths or a quick nature break can shift everything.
These are micro-adjustments with macro impact.
And as someone who believes in empowerment through rewiring, I see biohacking as one of the most practical ways to feel more in charge of how you show up—mentally, physically, and emotionally.
You don’t need to do everything. Just start small.
