Not long ago I wrote about how I built a browser-based board game called "Growing City" in three days using AI — and how the hardest part wasn't the code at all. Some time has passed, and I wanted to share what happened next. Layout Bugs While vibe-coding solo, I only tested on my own screen, resolution, and browser. The problem surfaced as soon as real users joined with different setups: some people saw everything misaligned, some things got clipped, some cards overlapped each other. This is how it looked on some screens I had to rewrite the layout to use adaptive sizing so the game looks correct regardless of screen resolution. It should work now — but if something still looks off on your end, let me know and I'll fix it. Bots Started Talking Another change, unrelated to bugs. The service started feeling more alive. Previously, bots just played: rolled dice, bought cards, said nothing. Now they react in the chat to what's happening in the game — if someone's building gets taken, if someone buys an expensive card or runs out of money. It's a small thing, but the game feels noticeably more lively. An empty game with silent bots versus a session where someone's commenting on what's happening in chat — it's a meaningfully different experience, even though the game itself is the same. Thank You to Early Players A special thanks to everyone who tried the game after my first article. And extra thanks to a user with the nickname SHAM, who pointed out that the game rules never said you can't buy multiple purple cards in a row — even though the game itself has that restriction. Fixed! What's Next The project is still going. I'm thinking about ads and other ways to bring in players. Without new users, it's hard to get feedback — and without feedback, it's hard to know what to fix or improve first. The unit economics don't quite work out yet: paid acquisition costs more than I'm willing to invest at this stage. I'll keep figuring it out. If you have ideas on how to find playe

One of Kalshi’s most prominent traders tells WIRED he’s swearing off Spotify-related markets until the issue is resolved.

You merge the PR. The build passes. The code does what you expected it to do. You move on. That is review for most engineers. A final read. A feeling that things looked right before the branch closed. I did it the same way for years. Three phases had already run before this one. Think had scoped the work, Plan had written the requirements, Build had shipped a diff that matched the plan exactly. I trusted that the chain held. I had never actually checked. Then I ran the Review phase, and checking turned out to mean something specific: not does this work, but does this requirement hold up, and what is my evidence. I went in expecting to approve it or send it back. The phase gave me three answers instead: covered, partial, missing. I found out what they meant one requirement at a time, starting with the one I almost got wrong. I had been giving impressions, not verdicts The notification scheduler used a queue to manage dispatch. Every call to the external provider went through it. The provider was never exposed directly. The requirement said the provider must be notified. It was notified, exactly the way I had pictured it. I almost called it covered and moved to the next line. The Review phase stopped me there. But the requirement said must be notified , not how. The queue had introduced a call order and a timing the requirement never anticipated. Nothing was broken. Something had changed shape, quietly, and nobody had written that shape down. I sat with that for longer than I expected to. Not because the code was wrong. Because I could not immediately tell you whether the change mattered. The same pass gave the shim from Plan a different verdict on the same page: covered. Mapped to the requirement it existed to satisfy, no gap between what was promised and what was in the diff. One requirement held exactly the shape it was given. The other had quietly grown a new one. Same review. Same pass. Two verdicts. Partial is not a softer word for broken. It is the verdict for

Introduction Most projects start with a single repository. Imagine you're building an e-commerce platform: a Next.js storefront for customers, a React Native mobile app, and a NestJS backend API. Splitting these into three repositories feels like the obvious, clean solution. ecommerce-web ecommerce-mobile ecommerce-api For the first few months, this works fine. Then the project grows, and the cracks start to show: You copy utility functions between repositories instead of importing them. You duplicate TypeScript interfaces across the frontend, mobile app, and API. Your frontend and backend drift apart because each repo defines its own version of the same models. Updating one shared component means editing it in three different places. Eventually, maintaining the project becomes harder than building new features. If that sounds familiar, you're not alone — it's exactly the problem monorepos were designed to solve. In this article, we'll cover: What a monorepo actually is, and how it differs from a multi-repo (polyrepo) setup Why engineering teams choose it How Turborepo makes monorepos fast instead of slow A practical, production-ready structure for a Next.js + React Native + NestJS monorepo Common mistakes and best practices Whether you work with React, Next.js, React Native, or NestJS, these concepts will help you build projects that scale without becoming a maintenance burden. The Problem With Multiple Repositories A typical multi-repo setup looks like this: web-app/ mobile-app/ backend-api/ shared-components/ Each repository has its own package.json , dependencies, CI/CD pipeline, Git history, and versioning strategy. It looks clean at first — but as the project grows, several problems appear. 1. Code duplication You write a helper function once: export function formatPrice ( price : number ) { return `$ ${ price . toFixed ( 2 )} ` ; } Both the web app and the mobile app need it, so instead of importing it, someone copies it. Now there are two versions. When one

Cursor hopes to continue offering third-party AI models after it's acquired by SpaceX, testing the relationships between frontier AI labs.

From what I understand, reviewers usually do not directly vote for these categories or nominate papers themselves. So how does the selection process typically work? Here are specific questions I wonder - Who actually selects the candidates: ACs, SACs, program chairs, award committees, or a separate committee? - Do ACs or committees read the camera-ready version, or is the decision based on the originally submitted/reviewed version? - Is the selection mostly based on reviewer scores, or do factors like novelty, impact, and discussion among ACs play a bigger role? submitted by /u/National-Resident244 [link] [留言]

I have not seen anyone put out a date for a new rocket, and actually hit it.

Just a ML fresher asking a genuine, since Mamba is more popular and saves computer (O(n)). Thanking you in advance ! submitted by /u/SoloLeveller07 [link] [留言]

Early reports indicate there may be another case, but spread is thought to be localized.

I am a mid to late stage PhD student in ML. I've known this before, but only recently I started feeling this urgently: my mathematical foundations are shaky, because I kept "learning-things-as-I-go" when working on various problems. I likely have only a year or two left until I graduate, and before I do so, I want to really dedicate some time and focus to brush up on the fundamentals. Primarily, I want to improve my knowledge in Linear Algebra, Probability Theory, and Functional Analysis. For Lin. alg., I am looking at "Linear Algebra done right", and I think this book is sufficient for the topic, unless anyone thinks otherwise. I am not sure where to start for probability, as well as functional analysis. Rudin's books give me headaches. I instead started reading "A primer on RKHS" ( https://arxiv.org/abs/1408.0952 ) to "dip my toe" into functional analysis. Apart from the above, I might re-read PRML book (I've only read specific chapters before), and try to finish Pat Kidger's Just-Know-Stuff list ( https://kidger.site/thoughts/just-know-stuff ). Thoughts? Anyone have any book/resource recommendations? Someone told me to look into "the bright side of mathematics" on YouTube, anyone ever go through the videos there? I'm aware finding good, digestible resources is less than 10% of the challenge. The difficult part is sticking through and actually reading/working through these topics, while still juggling other academic responsibilities. submitted by /u/mvreich [link] [留言]

by Peter Yang, Behind the Craft Today, I want to share 18 hot takes on where I think the AI market is headed. AI is in a weird place right now. The government is restricting access to frontier models, enterprises are becoming conscious of token costs, and everyone’s trying to rebuild their product for agents first instead of humans. I’ve interviewed dozens of AI leaders and spent far too much time following these topics on X/Twitter. Here are 18 hot takes on where I think AI is headed next: The frontier-only AI stack is collapsing The AI super app era is here Traditional software risks becoming a dumb pipe for agents Cloud agents and collaboration are the next wave The Frontier-Only AI Stack Is Collapsing Tokenmaxxing at frontier API prices makes no sense. Uber burned through its entire 2026 AI budget in 4 months, Microsoft moved engineers off Claude Code due to cost, and companies are realizing that running everything on frontier models can get expensive fast. Tokenmaxxing makes sense when you’re on a subsidized $200/month plan but is unsustainable at API rates. Companies will rely on a portfolio of models. Coinbase recently cut its AI spend nearly in half by switching engineers to Chinese open-source models like GLM and Kimi. Airbnb and Pinterest have done the same with Alibaba’s Qwen models. I believe that this will be the default path forward — using frontier for high-stakes work and cheaper models for everything else. China’s open-source strategy is working. Chinese models are taking market share from frontier models at US companies. China is also building the full AI stack — from energy (e.g., solar, nuclear) to data centers to domestic chips. The Chinese government is planning a $295B investment in AI data centers with at least 80% of the chips built domestically. Frontier labs are in a catch-22 situation. If they release great open-source models, they might undercut their own frontier API revenue. If they gate the best models behind a trusted list, companies

Frameworks like Lean Six Sigma and business process management (BPM) first gained traction because they promised clarity in the chaos—a structured way to bring order to messy, sprawling operations. Lean Six Sigma emphasized statistical rigor and quality control; BPM created end-to-end maps of how work should flow across departments. Both offered a repeatable way to…

When the enemy is in distress, exploit the opportunity to seize advantage. — The 36 Stratagems, Loot a Burning House Who's Leo — In the last story , he was CoreStack's backend lead — the guy who built the core system alone over five years with zero P0 incidents. Then a new CTO named James showed up, spent $8M on his old employer's product, and laid off Leo's entire team. Thirteen days later, that $8M AI system collapsed — three agents fighting over context, OOM taking down six GPU servers, a 37% order duplication rate, and 2,300 customer complaints. Leo pulled the old system off his laptop, flipped one line of Nginx config, and restored service in thirty seconds. The CEO called him at 3 AM begging him to come back. He came back. Three conditions: kill the paid AI product, AI assists only — never touches the primary pipeline — and engineers decide the architecture, not the guy writing checks. The CEO agreed to all of it. So who's Leo now: CoreStack's CTO. Technically confident to the point of arrogance. Zero talent for upward management. No idea how many people he pissed off on the board with those conditions. Doesn't care. He only knows one thing — the system he built is still running. That's all the proof he needs. Then a Slack message cut him off. The Signal 12:47 AM.
