One Million Passports Leaked Online

A database of almost a million passports from around the world was leaked online. Note what happened. A high-value credential—a passport—was used in an ancillary low-value authentication system: ID verification for cannabis dispensaries. And it’s the low-value system that got hacked, putting the high-value credential at risk.

Startups Don't Need "Perfect" Code. They Need "Malleable" Code

Why adaptability beats perfection in startup software development The Startup Trap: Building for a Future That Doesn't Exist Yet Many startup founders make the same mistake. They spend months building the "perfect" product architecture. The code is clean. The design patterns are flawless. The test coverage is near 100%. The infrastructure can scale to millions of users. There's just one problem: They don't have any users. In the startup world, survival depends on learning faster than competitors, not on creating the most elegant codebase. Product-market fit is uncertain. Customer needs change weekly. Business models evolve. Features that seemed critical last month become irrelevant the next. In that environment, the biggest advantage isn't perfect code. It's malleable code . Code that can bend, adapt, and evolve as the business learns. What Is Malleable Code? Malleable code is software that is easy to change. It isn't necessarily perfect. It isn't over-engineered. It isn't designed to solve every future problem. Instead, it's designed to support continuous experimentation. Malleable code allows teams to: Launch MVPs quickly Test assumptions rapidly Respond to customer feedback Pivot when necessary Add new features without major rewrites Remove failed features with minimal effort Think of it this way: Perfect code optimizes for certainty. Malleable code optimizes for uncertainty. And startups operate almost entirely in uncertainty. When you're still searching for product-market fit, the ability to adapt is often more valuable than technical elegance. Why "Perfect" Code Often Hurts Startups Software engineers love solving technical problems. It's natural. Building a scalable architecture feels productive. Refactoring code feels productive. Designing the perfect system feels productive. But startup success isn't measured by code quality. It's measured by business outcomes. Questions such as: Are customers using the product? Are they paying for it? Are they returning? A

I Almost Didn't Learn Programming Because I Was Bad at Math

For a long time, I thought programming wasn't for people like me. Not because I wasn't interested in technology. Not because I didn't enjoy solving problems. But because I kept hearing the same thing over and over again: "You need to be good at math to become a programmer." The more I heard it, the more I believed it. Whenever I saw developers building websites, apps, or cool projects, I assumed they were all math experts. 🧮 I imagined them solving complex equations all day while I struggled with basic math concepts. So before I even wrote my first line of code, I had already convinced myself that programming probably wasn't for me. And honestly, I think many beginners feel the same way. 🤔 The Fear Was Bigger Than The Reality When I finally started learning programming, I expected math to be my biggest challenge. It wasn't. My biggest challenge was understanding why things weren't working . I spent hours trying to figure out: Why isn't this button working? 🖱️ Why is this variable undefined? 🤨 Why did this code work yesterday but not today? 😅 Why did fixing one bug create three new bugs? 🐛 Very quickly, I realized that programming wasn't testing my math skills nearly as much as it was testing my patience and problem-solving ability. Most of the time, the challenge wasn't: "Can you solve this equation?" It was: "Can you figure out what's causing this problem?" 🧠 Logic Matters More Than Most People Think One of the biggest lessons I learned is that math and logic are not exactly the same thing. Yes, math uses logic. But you don't need to be a math genius to think logically. Programming is often about breaking a big problem into smaller, manageable pieces. For example: If a user clicks a button, what should happen next? If data is missing, what should the application do? If an error occurs, how should it be handled? That's logic. You're constantly thinking: "If this happens, then what should happen next?" And honestly, that's a huge part of software development. Some of

AI Agents and Persistent Context: What design.md Teaches Us

A GitHub repository called design.md has been trending recently, accumulating over 1,400 stars. The concept is straightforward: provide AI agents with a persistent design document they can reference throughout their work. This approach addresses a practical challenge in agent development that many teams encounter. The Context Challenge When working on complex tasks, AI agents need to understand the broader picture. What's the architecture? What constraints exist? What approaches have been tried before? Typically, agents get context from: Current conversation (limited window) Code comments (often outdated) Documentation (if it exists) The issue is that this context is fragmented and temporary. When conversation moves forward, earlier context disappears. When documentation is outdated, agents make incorrect assumptions. A design.md provides a single source of truth that persists across sessions. What Belongs in design.md An effective design.md answers these questions: What are we building? Beyond feature lists, document the core purpose. Why does this project exist? What problem does it solve? What are the key architectural decisions? Document major choices and their rationale: "PostgreSQL was chosen over MongoDB because ACID guarantees are required for financial transactions" "Microservices architecture was adopted because components have different scaling requirements" What constraints exist? Technical constraints (performance requirements, browser support), business constraints (budget, timeline), and regulatory constraints (GDPR, HIPAA). What has been tried before? Document failed approaches to prevent agents from suggesting rejected solutions. What are the current challenges? Known issues, technical debt, areas needing improvement help agents prioritize work. How Agents Use design.md When starting a task, agents can: Read design.md to understand context Make decisions aligned with documented architecture Avoid solutions violating constraints Reference design.md i
