A solar and home energy storage company is expanding into AI data centers, but not by building one - instead, it's offering to pay its customers to put its compute units in their homes. Sunrun is launching a pilot program for a new "distributed AI compute" program that will "place numerous compute nodes in homes […]

Builder Journal · ARC Prize 2026 There is a moment in every role-playing game where you load your character with so much heavy gear that they can barely walk. Strongest sword in the game, can't reach the fight. I did the machine-learning version of that this month. I kept making my agent more capable, and the scoreboard kept punishing me for it, and it took me two tries to understand that the upgrades were the problem. A quick frame, in case this is your first entry in this thread : I'm in the ARC Prize 2026, building an agent that has to learn small games it has never seen, with no instructions. As the benchmark's creator measured it, the hardest part by far is the piece that figures out the rules of a game by experimenting on it. So that piece is where I have been pouring my effort. The obvious upgrade The obvious way to make that piece better is to teach it more kinds of games. If it can model three families of puzzle today, teach it a fourth, and it should win more. So I did exactly that. I built support for a new class of game it could recognize and solve, wrote it carefully, tested it, and confirmed the thing I wanted to confirm: the agent now beat a game it provably could not beat the day before. Real, verified, new capability. Not a story I was telling myself, a genuine new skill on the board. Then I submitted, and the score went down. Twice This is the part I want to be honest about, because one bad result is noise and two is a pattern. My agent's attempts to use this theory-building component had already been underwhelming on the real board, landing around 0.05, 0.07, and 0.09 across earlier tries, all of them under the 0.25 my plain, careful agent scores when it does not reach for the fancy component at all. The fourth skill was supposed to turn that corner. Instead the next submission came in at 0.04, the worst of the lot. I had added ability and the number had dropped, again. So I stopped adding and started counting. I ran a survey across twenty-five of

AI search is changing how brands get discovered. Ranking on Google is no longer the only goal. Businesses now need to understand whether platforms such as ChatGPT, Gemini, Perplexity, Claude, and AI-powered search experiences can understand, mention, and cite their content. That is where GEO checkers and AI visibility tools come in. Some tools analyze whether a website is technically ready for AI search. Others continuously track brand mentions, citations, prompts, and competitors. Below are the 10 best GEO checker and AI visibility tools in 2026 .

Everyone talks about AI writing code. Nobody talks about AI debugging code. Bad error messages are the worst, we've all seen them. You open the logs or run your program and see something like this... Error: something went wrong It leaves you asking: What happened? Where did it happen? Why did it happen? How do I fix it? You might have written some of these pretty silly error messages, I know I have. They don't help us fix software quickly because we first have to figure out why the error happened. Rust has been shipping fantastic error messages for years. Take this example where I accidentally call println instead of println! . $ cargo run 101 ↵ Compiling ducksay v0.2.0 (~/oss/ducksay) error[E0423]: expected function, found macro `print` --> src/main.rs:51:3 | 51 | print("{}", render_with_style(&message, cli.width.get(), style)); | ^^^^^ not a function | help: use `!` to invoke the macro | 51 | print!("{}", render_with_style(&message, cli.width.get(), style)); | It's fantastic! It tells you what went wrong, where it occurred, and how to fix it. When you're building software, you should make your error messages exceptional (punny 😂). Here's another example from Vite+ where I had a syntax error in the config file. $ vp dev failed to load config from ~/oss/test-ssr-on-aws/vite.config.ts error when starting dev server: Error: Build failed with 1 error: [PARSE_ERROR] Error: Unexpected token ╭─[ vite.config.ts:5:3 ] │ 5 │ , │ ┬ │ ╰── ───╯ Now imagine debugging code with generic error messages that tell you absolutely nothing helpful. You'll have to manually trace through the code to figure out what the heck is going on. AI agents run into the same problem. If the error tells them almost nothing, they have to spend extra time reading files, tracing execution paths, and making additional tool calls just to understand what failed. So what can we do to help humans and AI? Here are some of my top recommendations for writing good error messages. 1. Be descriptive and specific W

This week should have been a celebration for Doom developer id Software. The studio just launched Revelations, a meaty expansion for Doom: The Dark Ages that adds a powerful new weapon and more demonic levels to blast through. Even though I hadn't picked up The Dark Ages for more than a year, it only took […]

The AC culture wars may be solved by advances in environmentally friendly technology.

In the near future, AI -powered surveillance systems will be able to track everything we do in public, and much of what we do in private. And if we do something wrong—shoplift, litter, jaywalk, you name it—the system will notice, retain it, tie it to your official government record, communicate that fact to you, and provide real-time alerts to any relevant authorities… and maybe also to the general public. Think of these systems as automated speed cameras, but on steroids. Only they’ll enforce not just speed limits, but any other rule you can imagine. And you won’t receive a ticket weeks later by mail; you’ll be informed about and fined for your violation immediately...

GitHub has made the redesigned GitHub Copilot CLI terminal interface generally available. It adds a tabbed layout for sessions, gists, issues, and pull requests; an in-session, form-driven setup for MCP servers, skills, and plugins that avoids hand-editing config files; and a cleaner, theme-aware, more accessible UI with screen reader support.

TL;DR AI editors love writing recursive merge helpers, and most of them are open to prototype pollution. One crafted JSON payload with a proto key can flip an isAdmin flag on every object in your app. Guard the keys or merge into a structure that has no prototype. It is a three-line fix. I asked Cursor for a "deep merge two config objects" helper last week. It gave me eight lines that worked perfectly on my test data. It also gave me a prototype pollution hole big enough to walk through. The function looked fine. That is the problem. Prototype pollution does not show up when you run the happy path. It shows up when someone sends you a key called proto . The code Cursor handed me (CWE-1321) function merge ( target , source ) { for ( const key in source ) { if ( source [ key ] && typeof source [ key ] === ' object ' ) { target [ key ] = merge ( target [ key ] || {}, source [ key ]); } else { target [ key ] = source [ key ]; } } return target ; } Now feed it something a user controls, like a parsed JSON request body: merge ({}, JSON . parse ( ' {"__proto__": {"isAdmin": true}} ' )); ({}). isAdmin ; // true You did not set isAdmin on anything. You set it on every object in the process. Any later check like if (user.isAdmin) now passes for objects that never had that field. Why this keeps happening The recursive merge pattern is all over old blog posts and StackOverflow answers, and almost none of them guard the special keys. The model learned merge from that corpus. It reproduces the shape of the answer, including the missing check, because the missing check never breaks a test. A for...in loop also walks keys like proto when they arrive as ordinary string properties from JSON.parse, which is exactly how the payload gets in. The fix Skip the dangerous keys, or merge into something that has no prototype to pollute. function merge ( target , source ) { for ( const key in source ) { if ( key === ' __proto__ ' || key === ' constructor ' || key === ' prototype ' ) continue ;

I built an API gateway that routes between OpenAI, Anthropic and Gemini. I figured integrating both providers would be the hard part. It wasn't. Calling their APIs is maybe an afternoon of work each. The hard part showed up later, the first time something went wrong. The moment it broke Early on, my error handling was basically: catch whatever the provider throws, forward the status code, move on. } catch ( error ) { res . status ( error . status || 500 ). json ({ error : error . message }) } This worked fine until I actually looked at what each provider sends back when something goes wrong. OpenAI wraps its errors in an object with a type and sometimes a code . Anthropic wraps its errors differently, with its own type field that means something else entirely. A 429 from one provider might mean "you're sending too fast, back off." A 429 from another context might mean something closer to "we're out of capacity right now, this isn't really about your rate at all." If you're just forwarding error.status and error.message straight through, none of that nuance survives. Your own error handling ends up being provider-specific whether you meant it to be or not, because the shape of the failure is different depending on who you called. What I built instead Instead of trusting each provider's raw error shape, every call now normalizes into the same internal error model before it reaches the response: } catch ( error ) { const classified = classifyProviderError ( error ) res . status ( classified . httpStatus ). json ({ error : ' AI provider error. Please try again. ' , error_class : classified . error_class , provider : classified . provider }) } error_class is one of a small fixed set: rate_limited , overloaded , quota_exceeded , invalid_request , authentication_error , server_error . That's true regardless of which provider actually failed. The raw provider error still gets logged for me to debug, but what the caller sees is the category of failure, not the provider's spe

" Shifting from Prompt Engineering to Infrastructure Orchestration " Week 2 was a mix of excitement, curiosity, and a little bit of frustration. I learned a lot of new concepts, but I also realized that the best way to understand them is by actually trying them out. Reading or watching tutorials helps, but experimenting with the tools made everything click for me. One of the topics I enjoyed learning about was Claude Code. Before this week, I mainly thought of AI as something that answers questions or helps write content. Seeing how Claude can assist with coding, debugging, and understanding projects made me see it differently. It feels less like a search engine and more like someone you can work with while building something. That really changed how I think about using AI in development. Another interesting topic was Skills. I liked the idea that you can give an LLM specific skills so it behaves more like a specialist instead of a general assistant. It made me realize that the quality of the output doesn't only depend on the model itself, but also on how you guide it and what tools or skills you give it. That was something I hadn't really thought about before, and I can already see how useful it could be for different types of projects. I also learned about Subagents, which was a new concept for me. At first, I didn't really understand why you would need multiple agents instead of just asking one AI to do everything. But after learning more about it, I started to see the benefit. Having different agents focus on different tasks seems like a much cleaner and more organized way to work, especially for bigger projects. The biggest challenge I faced this week was running out of tokens while practicing. It happened a few times, and honestly, it was a little annoying because I would be in the middle of exploring an idea and suddenly had to stop. Even though it was frustrating, it also made me think more carefully about how I write prompts and how I use my conversations.

In this podcast Shane Hastie, Lead Editor for Culture & Methods spoke to Gabriela Moreira about making formal methods accessible through the Quint specification language, how AI is dramatically lowering the barrier to entry for formal specification and model-based testing, and why defining correct system behaviour remains essential human work in an AI-driven world.

Adding cloud regions changes latency and cost in ways simple math can't capture. This article presents a framework from multiple launches: decompose your latency budget before committing to infrastructure, choose deployment patterns by consistency and traffic profile, and optimize before expanding. A phased approach cut latency 35% through routing alone, before a new region brought it under 60ms. By Uttara Asthana

Artificial intelligence has transformed software development. Instead of simply generating code snippets, modern coding assistants can understand entire codebases, refactor applications, write tests, debug issues, and even execute development workflows. Among the most capable tools available today are Claude Code and Codex. While both are designed to accelerate software development, they take different approaches to coding assistance. This article compares their strengths, weaknesses, and ideal use cases. What Is Claude Code? Claude Code is Anthropic's command-line coding assistant built around the Claude family of language models. Rather than functioning as a traditional autocomplete tool, Claude Code works as an AI development agent that can inspect projects, edit files, explain code, write tests, fix bugs, and help developers navigate large repositories. Its workflow is centered around natural language. Developers describe what they want, and Claude Code performs the necessary steps while keeping the developer involved throughout the process. Key features Deep understanding of large codebases Multi-file editing Test generation Refactoring assistance Terminal-based workflow Strong reasoning for complex programming tasks Excellent documentation generation What Is Codex? Codex is OpenAI's AI coding agent designed to help developers write, understand, and modify software. Unlike the original Codex model introduced in 2021, today's Codex operates as a software engineering agent capable of working across repositories, generating code, fixing bugs, creating pull requests, running tests, and assisting with development workflows. Codex integrates closely with OpenAI's ecosystem and focuses on turning natural language instructions into production-ready code while maintaining awareness of project context. Key features Repository-aware coding Autonomous task execution Code generation Bug fixing Test writing Pull request assistance Integration with modern development workflow

Building an explainable AI platform that helps district administrators allocate resources and farmers make better crop decisions using Gemini, Vertex AI, BigQuery, and Google Cloud. Climate disasters are not just weather events. They are decision problems. When forecasts predict a strong El Niño, governments do not simply need more data. They need answers to questions like: Which districts will be affected first? Where should limited water resources be sent? Which crops are likely to fail? What should farmers sow instead? Why is the AI recommending this action? Existing dashboards provide plenty of charts. Very few provide decisions. That became the motivation behind El Niño 2026 Decision Copilot , an AI-powered decision intelligence platform built during the Google Cloud Gen AI Academy APAC Hackathon . The Problem India depends heavily on the monsoon. A severe El Niño can lead to: Rainfall deficits Reservoir depletion Groundwater stress Crop failures Rising food prices Rural employment challenges The information already exists across dozens of government portals, weather services, satellite datasets, and agricultural reports. The challenge is that it is scattered. District collectors do not have time to manually combine: Weather forecasts NDVI satellite imagery Reservoir levels Mandi prices Contingency plans Drought indicators Farmers face an even bigger challenge. Most need a simple answer: Given my district, should I plant the usual crop this season? The Goal Instead of building another dashboard, I wanted to build an AI system that reasons over multiple data sources and produces explainable recommendations. The platform serves two audiences through the same intelligence engine. District Administrators They receive: District risk scores Interactive risk maps Reservoir outlook Crop stress indicators Resource allocation recommendations AI-generated explanations Instead of simply showing that a district has high risk, the system explains why . Farmers Farmers intera

Hey DEV community, I recently launched bgchanger.video , an AI video background changer for removing or replacing video backgrounds directly in the browser. The idea is simple: many creators, indie hackers, marketers, and product teams need cleaner videos, but traditional editing tools can feel too heavy for quick background cleanup. With bgchanger.video, you can: Upload a video Remove the original background Export with a transparent background Replace the background with a solid color Download the result in formats like MP4, WebM, MOV, MKV, or GIF Keep the original audio when needed I built it for quick workflows like: Product demo videos Social media clips Creator videos Ad creatives Cleaner profile or presentation videos Background cleanup before further editing The current version focuses on making the workflow straightforward: upload, configure, generate, download. I am still improving the product and would love feedback from other builders: Is the workflow clear enough? What export options would you expect? Would you prefer templates, custom background uploads, or batch processing? What would make this useful in your own video workflow? You can try it here: https://bgchanger.video Thanks for checking it out. Feedback is very welcome.
