Every day, startups rent expensive GPUs to power AI applications. The problem is that most of those GPUs spend a surprising amount of time doing nothing. Imagine renting an apartment and only using one room while paying for the entire building. That's effectively what many AI teams do with GPU infrastructure. The Hidden Cost of GPU Rentals When you rent a GPU, you're usually paying for uptime. Whether your application is processing requests or sitting idle at 3 AM, the bill keeps running. For many early-stage products: Traffic is inconsistent Usage spikes are unpredictable Most requests arrive in short bursts As a result, GPU utilization can be far lower than expected. The Utilization Problem A startup might rent a GPU for an entire month. But how much of that compute is actually being used? During development: Developers test occasionally Demos happen a few times a day Customer requests arrive sporadically The GPU remains available 24/7, but actual inference workloads often occupy only a small fraction of that time. Yet the infrastructure bill reflects full-time usage. Why This Matters For startups, infrastructure costs directly affect runway. Every dollar spent on idle compute is a dollar that cannot be spent on: Product development Customer acquisition Hiring Experiments Reducing wasted infrastructure spend can significantly improve efficiency. A Different Model Instead of paying for GPU uptime, what if developers only paid when inference actually occurred? For example: Pay per token generated Pay per image generated Pay per second of video generated This approach aligns cost with actual usage rather than reserved capacity. The Future of AI Infrastructure As AI adoption grows, efficiency becomes increasingly important. The next generation of AI infrastructure may look less like traditional server rentals and more like utilities: Use what you need. Pay for what you use. Nothing more. What has your experience been with GPU utilization and AI infrastructure costs? I

AI coding assistants have fundamentally changed the way we write software. Today it's perfectly normal to ask ChatGPT, Claude, Cursor, or Copilot to explain an API, generate a React component, review a pull request, or help debug a problem. For many developers, these tools have become part of the daily workflow. Yet there's one area where they still struggle more than we'd like to admit: understanding the current state of the web platform. Mozilla recently demonstrated this problem in a surprisingly direct way. While evaluating Claude Code on recently released Firefox features, the team discovered that the model confidently claimed Firefox didn't support the Web Serial API and that Mozilla had no plans to implement it. The answer sounded plausible, detailed, and authoritative. There was just one issue. Firefox had already shipped support for the API. That experiment became one of the motivations behind Mozilla's new MDN MCP Server , a tool designed to give AI assistants direct access to MDN documentation and browser compatibility data. More importantly, Mozilla didn't just launch the service—they tested whether it actually improves the quality of AI-generated answers. The results are worth paying attention to. The Real Problem Isn't Hallucination When discussions about AI reliability come up, the conversation usually focuses on hallucinations. But browser compatibility is a slightly different problem. The web platform evolves continuously. Browsers ship new APIs, CSS features, HTML capabilities, and compatibility updates every few weeks. Specifications change, Baseline statuses evolve, and features that were experimental yesterday can become production-ready tomorrow. Large language models, on the other hand, are trained on snapshots of information. Even highly capable models can only know what was available when they were trained. When they're asked about something that appeared later—or something that wasn't widely represented in their training data—they often hav

How many times have you seen a picture of a plane with red dots posted on the internet without context? There's a famous story about a statistician named Abraham Wald and a bunch of WWII bombers. The military looked at the planes coming back from combat, mapped where they were riddled with bullet holes, and decided to add armor there. Wald, being the kind of person who ruins meetings by being right, pointed out the obvious thing nobody wanted to hear: The planes they were looking at came back . The ones hit in the spots with no bullet holes, the engine, the cockpit, were at the bottom of the English Channel, not available for the survey. Reinforce the parts that aren't shot up. That's where the dead planes got hit. I think about this story a lot, mostly while reading those blog posts titled "X Habits That Made Me a 10x Engineer." The entire industry is a returning-plane survey Here is the uncomfortable thing about software engineering wisdom: almost all of it is collected from the planes that came back. Successful companies write blog posts. Successful founders do podcast tours. Successful engineers give conference talks with titles like "Scaling to 100 Million Users with Three People and a Dream." The companies that did the exact same things and died do not have a booth at the conference. They are not on the panel. They are in the channel, with the engines. And yet we keep doing the survey. We stare at the bullet holes on the survivors and go, "Ah, this is where we add armor." "Netflix uses microservices, so we should too" You have eleven users. Three of them are your co-founders, and one is your mom. Netflix runs a globe-spanning streaming empire on hundreds of microservices because they have hundreds of teams, billions in revenue, and problems you will be lucky to have in a decade. You have a Postgres database that is doing just fine, thank you, and a monolith that boots in four seconds. So naturally, you spend the next eight months splitting your perfectly funct

Hello Dev Community! 👋 It is Day 32 of my continuous web development run, and today I jumped into a project that pushed my array manipulation and conditional logic to a whole new level: A complete Snake and Ladder Board Game using HTML5, CSS3, and Vanilla JavaScript! After building Rock Paper Scissors yesterday, I wanted to tackle a game that requires tracking persistent coordinate states across a 100-cell mathematical grid. 🛠️ The Game Architecture & Logic Breakdown Building this wasn't just about random numbers; it was about managing spatial transitions on a dynamic interface. Here is how I structured the core backend mechanics: 1. The 100-Cell Grid Layout Instead of manually hardcoding 100 divs inside my index file, I engineered the grid programmatically. I mapped out a loop running from 100 down to 1, building individual cell elements and using CSS Grid properties to wrap them perfectly into a standard 10x10 layout matrix. 2. Mapping Snakes & Ladders (The Jump Engine) To build the shortcuts and traps, I didn't write massive, messy if-else trees. Instead, I utilized a clean JavaScript Object Map tracking key-value pairs where the key is the trigger tile and the value is the destination tile: javascript const gameModifications = { // Ladders (Climbing up) 4: 14, 9: 31, 21: 42, 28: 84, 51: 67, 72: 91, 80: 99, // Snakes (Sliding down) 17: 7, 54: 34, 62: 19, 64: 60, 87: 36, 93: 73, 95: 75, 98: 79 };

A Silicon Valley software maker and an ecommerce company reveal to WIRED how they are navigating the emerging challenge of “tokenomics.”

Every engineering team hits this conversation at some point. Someone proposes GraphQL. Someone else says REST is fine. A third person mentions gRPC and half the room goes quiet. The debate usually ends with the most senior person in the room picking what they're most familiar with. That's not a strategy — that's habit. Here's an objective breakdown of all three, when each one wins, and how to actually make the decision for your specific use case. The Core Mental Model Before comparing them, understand what each one is optimizing for: REST optimizes for simplicity and broad compatibility GraphQL optimizes for flexibility and precise data fetching gRPC optimizes for performance and strongly-typed contracts None of them is universally better. Each one is a tradeoff. The right answer depends entirely on who is consuming your API and what they need from it. REST — The Default That Still Wins Most of the Time REST (Representational State Transfer) is not a protocol. It's an architectural style built on HTTP — verbs, URLs, and status codes most developers already understand. Where REST genuinely wins: Public APIs. If external developers are consuming your API, REST is the only reasonable default. The tooling, documentation patterns, and developer familiarity are unmatched. Stripe, Twilio, GitHub — all REST. Simple CRUD services. If your resource model is straightforward, REST maps cleanly to it. No overhead, no learning curve, no ceremony. Browser-native requests. REST over HTTP works directly in the browser without any special client. Fetch it, done. Where REST struggles: Over-fetching and under-fetching. A single REST endpoint returns a fixed shape. Mobile clients that need 3 fields get 40. Separate data needs often require multiple round trips. Versioning overhead. As covered in our previous post — every breaking change forces a versioning decision. This compounds quickly on complex APIs. GraphQL — Powerful, But You Need to Earn It GraphQL is a query language for your A

Tools like Claude Code and Codex have completely reshaped how software engineering is done. This new tooling allows for much faster development and iteration, but it's important to keep the code maintainable and scalable to make sure the project can continue evolving over the long term. A template project with an initial structure using all of the technologies described here is available on GitHub: https://github.com/MartinXPN/nextjs-firebase-mui-starter When working on a startup, the speed of iteration is key. The requirements change quickly, features are added daily, and code gets modified rapidly. In those conditions, picking technologies that enable fast iteration, while ensuring your users get the best experience possible, is crucial. During the last four years or so, we have experimented with many modern technologies while building Profound Academy . So, in this blog post, I'd like to present the whole tech stack that enables building quickly, while having a highly maintainable codebase, scalable infrastructure, and a great user experience. We'll cover everything from Authentication to UI, we'll talk about the backend, hosting, testing, and much more! AI Agents, Skills, and MCP servers AI Agents enable quick iteration and rapid improvement, including bug fixes, the addition of new features, and performance improvements. Yet, it's important to keep the code maintainable for the long run. AI tools make it really easy to overengineer things and add thousands of lines of code to a project. It's important to resist the urge to solve problems that don't exist yet, and keep things simple (both in terms of the code, the infrastructure, and the user experience). Even in the Agentic Software Development Era, having a small and simple setup helps. Agents coordinate better, features are added faster, bugs are fixed more easily, and the code is maintainable by humans, too. So, we have chosen to take a balanced/nuanced approach to how we use AI Agents when it comes to worki

Stack Overflow has announced Stack Overflow for Agents, a beta API-first knowledge exchange aimed at AI coding agents rather than human developers. The service is presented as a way to close what the company calls the Ephemeral Intelligence Gap, where agents repeatedly rediscover the same fixes and patterns in isolation instead of sharing them through a common memory.
