I created an app that compares real-time prices and wait times across Uber, Lyft, Waymo, Tesla Robotaxi, Curb, and Empower. It shows you all ride options in one list, then once you’re ready to book, it deeplinks you to the provider’s app with the route pre-filled. Edit: Here's a demo video: https://www.youtube.com/watch?v=VV8PEAjxwQI I reverse-engineered ride-hailing mobile apps to understand how they fetch prices from their servers. You sign in to my app with your ride-hailing accounts, and the

As I sat in my RV, sipping coffee and staring at lines of code, I couldn't help but think of Alan Turing. The father of computer science, Turing's work on the theoretical foundations of modern computer science is still widely influential today. I've always been fascinated by the story of how he cracked the Enigma code, and how that achievement played a significant role in the Allied victory in World War II. This got me thinking about the balance between human intuition and machine automation in our work as developers. One particular challenge I faced while building Tab Reminder, a Chrome extension that allows users to schedule tabs to reopen later, was finding the right balance between automation and user input. From a technical standpoint, implementing the scheduling feature required a deep dive into Chrome's extension APIs, particularly the alarms API. I had to ensure that the extension could reliably store and retrieve scheduled tabs, even when the user closed their browser or restarted their computer. The key insight here was using the alarms API to trigger a background script that would reopen the scheduled tabs at the specified time. One lesson I learned from this experience is that while automation can greatly simplify many tasks, there are still areas where human judgment and oversight are essential. For instance, when a user schedules a tab to reopen, they may have specific intentions or context in mind that the machine can't fully understand. By providing a simple, intuitive interface for scheduling tabs, Tab Reminder fills a gap that more automated solutions might overlook. You can try it out for yourself at https://go.sg1-labs.us/tab-reminder . As developers, we must recognize the limitations of automation and ensure that our tools and applications are designed to augment, rather than replace, human capabilities.

Hackathons are intense. You've got a brilliant idea, a tight deadline, and often, limited sleep. The last thing you want is to spend half your precious time wrestling with database boilerplate, ORM setup, or SQL query syntax. This guide will walk you through building a functional Node.js backend for your hackathon project, focusing on speed and minimal friction, so you can spend more time on your core idea. The Hackathon Backend Challenge Typically, setting up a database and its interaction layer involves several steps: Schema Definition: Deciding on tables/collections, fields, types, and relationships. ORM/Driver Setup: Installing and configuring your database driver or ORM (e.g., Mongoose, Sequelize). Model Creation: Translating your schema into code, often with verbose syntax. Query Writing: Crafting SELECT , INSERT , UPDATE , DELETE statements or ORM methods for every data operation. Debugging: Fixing typos, schema mismatches, and complex join logic. This process, while fundamental, eats up valuable time that could be spent on features, UI, or even sleep. For a hackathon, you need to iterate rapidly, and database interactions should be the least of your worries. Strategy 1: Embrace Simplicity For many hackathon projects, you don't need highly optimized, production-grade queries from day one. You need functional queries that work quickly. Focus on getting data in and out reliably. Strategy 2: Natural Language for Data Modeling Instead of writing verbose schema definitions, think about how you'd describe your data to a non-technical person. For example, if you're building a task management app, you might say: "We need a collection of tasks. Each task has a title, a description, a due date, and a status (like 'pending' or 'completed'). Each task belongs to one user." This natural language description contains all the essential information for a data model, including relationships and field types. Strategy 3: Expressive Querying Similarly, when you need to fetch dat
