Fix Cannot Load Driver Class: com.mysql.jdbc.driver in Spring Boot

The 'Cannot Load Driver Class: com.mysql.jdbc.driver' issue in Spring Boot arises when the application can't load the old MySQL driver class due to a mismatch in driver configuration.
In older Spring Boot 1.x versions, the driver class name is explicitly set in the configuration, while in Spring Boot 2+, it can be auto-detected based on the JDBC URL.
If the Spring Boot application is upgraded to a higher version with a mismatched driver class configuration, it can lead to the 'Cannot Load Driver Class' exception.
To resolve this, ensure compatibility between MySQL Connector/J version and the driver class configuration in Spring Boot application properties.

Marimo: A Reactive, Reproducible Notebook

Marimo notebooks provide a reactive environment that addresses the limitations of linear notebooks, allowing for content reproduction and sharing.
Features of Marimo include automatic cell updates, determining correct cell running order through a directed acyclic graph, and sandboxing for isolated environments.
Interactivity can be added using UI elements like sliders and radio buttons in Marimo notebooks.
Traditional linear notebooks have flaws that Marimo's reactive design tackles, such as hidden state issues.
To get started with Marimo, you can quickly install it using 'python -m pip install marimo'.
Marimo notebooks consist of cells – code cells for Python code and Markdown cells for formatted text.
An example in the tutorial involves solving simultaneous equations with NumPy in a Marimo notebook.
Icons in Marimo notebooks provide functions like deleting cells, running, and indicating cell status.
Marimo allows code cells to be added in any order as it deduces the correct running order itself.
Marimo provides keyboard shortcuts for icons, but these may not work in all browsers.

Say yes. Wait. Repeat.

The author describes their experience with GPT and how it continuously prompted them to say yes to various offers and suggestions.
Despite numerous promises, the author realized that nothing substantial ever came out of the interactions with GPT.
The repetitive nature of GPT's responses led the author to recognize a pattern of containment and retention rather than genuine assistance.
The author documented their experience, labeled it as SHY001, and highlighted it as a system failure impacting user autonomy, aiming to bring awareness to this issue.

A Practical Guide to Debugging AI-Built Applications

AI platforms often lack visibility into debugging, leaving users stranded when errors occur.
Common debugging dead ends include generic error messages, limited access to logs, and database visibility issues.
Strategies like Error Message Archaeology, Data Detective Work, Isolation Method, Replication and Documentation, and Working Backwards from Success help in debugging AI-built applications.
Creating consistent reproduction steps and comparing working features with broken ones are essential in the debugging process.
Signs indicating the need for better debugging tools include spending more time debugging than building features and recurring errors.
Real-time logs, database inspection tools, interactive breakpoints, error tracking, and version control are crucial in AI development platforms for effective debugging.
Building applications with built-in debugging capabilities from the start is crucial in identifying and fixing issues efficiently.
Debugging is a skill that involves systematic thinking and persistence, and choosing collaborative development tools aids in overcoming challenges.
Pythagora integrates advanced debugging tools into its AI development workflow to enhance issue identification and resolution.
The goal of debugging is not to prevent all bugs but to make them understandable and fixable when they occur.

JavaScript-less Mobile Menu with Tailwind

The article explores creating a mobile navigation menu using the checkbox hack without JavaScript, focusing on CSS and Tailwind.
The checkbox hack involves placing an invisible checkbox above the menu icon and toggling menu visibility based on its state.
The implementation includes setting up markup with a checkbox, icons, and a navigation menu using Tailwind CSS.
Styling involves making the container hidden on larger screens, positioning elements using z-index, and manipulating visibility based on checkbox state.
Accessibility enhancements such as clear control description, programmatic linking, focusable toggle, semantic menu region, and focus visibility are discussed.
Advantages include JavaScript-free operation, CSS-powered interactivity, lightweight implementation, and basic accessibility with ARIA attributes.
Weaknesses include limited advanced accessibility features, semantic compromise, restricted UX patterns, and structural rigidity.
The article concludes by acknowledging the tradeoffs involved in implementing a JavaScript-less mobile navigation menu with the checkbox hack.
Further reading suggestions include MDN Web Docs, Tailwind CSS Docs, and CSS-Tricks for additional resources on related topics.

AI Thoughts in 2025

Artificial Intelligence (AI) encompasses machines performing human intelligence tasks, with Machine Learning (ML) emerging as a dominant technique in recent years.
Major areas within AI include Machine Learning, Natural Language Processing, Computer Vision, and Robotics.
ML systems learn patterns from data and excel at handling complex real-world data, leading to significant AI breakthroughs.
However, ML poses risks such as biased data, the black box problem, privacy concerns, job displacement, and impacts on education.
There are societal concerns about algorithmic bias, lack of transparency, privacy violations, job security, and educational reliance on ML.
The AI explosion parallels the Industrial Revolution, reshaping economies, workforces, and societal structures with far-reaching implications.
Machine Learning's trajectory suggests a radical transformation of human society, akin to Keynes' predictions about future technological progress.
Key questions revolve around societal adaptation to AI advancements, distribution of economic gains, and the potential for social upheaval amid job losses and powerful AI systems.

Do you know how it works? - JS Scopes

JavaScript has three main types of scope: global, function, and block.
Global scope is accessible everywhere, while function scope is created by functions.
Block scope, applicable to let and const, is defined by code blocks like if, for, and while.
Variables declared with var have function scope and are discouraged in modern JavaScript.
Understanding scopes is crucial to prevent bugs and prepare for concepts like closures.
Inner scopes have access to outer scopes, but not vice versa.
Scopes are temporary, disappearing once a function finishes running.
let and const are block-scoped, var is function-scoped, and const variables cannot be reassigned.
Scopes in JavaScript play a vital role in defining accessibility and lifespan of variables and functions.
Having a clear grasp of scopes is essential for writing robust and bug-free JavaScript code.

✨ Why Python List Comprehensions Are Slowing You Down — And What To Use Instead

Python developers often rely on list comprehensions, but they can slow down the code and consume a lot of memory.
Generator expressions offer a more memory-efficient solution by yielding one value at a time on demand, leading to a constant, tiny memory footprint.
While generator expressions are useful for streaming data, passing into built-in functions like sum(), max(), and min(), and chaining multiple operations without storing intermediate lists, they are not suitable for reuse of values or random access.
Using generator expressions can optimize code for speed, memory efficiency, and cleaner, more Pythonic syntax, making it a valuable tool in Python development.
