Andy Oymus

In 2016, a man with no CS degree quit his job to study for a Google interview. He was an English major. A self-taught web developer. A former Korean translator in the US military. He studied 8 to 12 hours a day. For 8 months straight. Algorithms. Data structures. System design. Operating systems. Networking. Every topic Google asks. He tracked every minute of it on GitHub. He called the repo "Google Interview University." Then he applied to Google. Google never called him back. Here's the wildest part: The repo he left behind became one of the most-starred projects on GitHub. Over 343,000 stars. Used by thousands of devs to break into FAANG. He got hired at Amazon as a Software Engineer. His name is John Washam. The repo is now called coding-interview-university. Inside you get: - A multi-month study plan, week by week - Every CS topic Google, Amazon, Meta and Microsoft actually ask - Algorithm patterns with worked examples - System design from zero to senior - Big-O, data structures, trees, graphs, recursion, dynamic programming - Behavioral interview prep - Mock interview drills - Book and lecture recommendations he personally used - Flashcards, video resources, and a coding question practice plan Self-paced. Free. No course. No paywall. No upsell. Just one engineer's 8-month study log, open for anyone who wants to follow it. If you are preparing for a tech interview, this is the most complete free roadmap on the internet. 100% Open Source. (Link in the comments)

@10xdegendev @om_patel5 so he is an iOS Engineer @Tiktok. the pivot isn’t too difficult with AI to make a game if you know code. WDYT? @grok

@om_patel5 0% chance this was made in 2 weeks, and zero chance dev has no experience the assets would be the main bottleneck. ai sucks at making vg assets, and trying to patch together asset packs would not produce this much cohesion nice bait, cute game tho

THIS GUY VIBE CODED A FULL CAPYBARA FOOD DELIVERY GAME IN 2 WEEKS WITH CLAUDE CODE you play as a capybara delivering food on a bike. orders stack on the back, you have a phone with apps in-game and the whole delivery system is realistic 2 weeks, zero game dev experience, and ENTIRELY AI generated the full stack: > claude code for all the code > three.js for the 3D engine > suno for original music > elevenlabs for sound effects and voice > GPT images-2 and grok for textures and illustrations > tripo3d for generating all the 3D assets the cinematics are all in-game too. he asked claude to build a cinematic editor with timeline controls, camera animation, and transitions. then he just placed the cameras himself his workflow was more planning than coding (obviously): > come up with the core mechanic > plan every feature using claude /plan mode > generate assets with AI tools > spend most of his time on the final polish, prop placement, and making the design feel right he said the human part is what most vibe coded games are missing. AI can generate everything but having taste for what looks good and what feels right is still on you the game is playable right now in the browser this is what vibe coding is actually capable of in the game dev space right now a year ago this would have taken a small team of developers, a sound designer, and an artist working together for months now one person with no experience can ship a polished playable game with story, music, and mechanics in 14 days the tools keep getting better and the barrier to making real games keeps getting lower

Goodbye paid course downloaders and sketchy Chrome extensions. Someone just built an open-source desktop app that pulls media from 1000+ sites... and it's wild. You paste a link. You get the file. That's it. It's called OmniGet and it handles everything: - Full Udemy and Hotmart courses with login (videos, attachments, descriptions) - Telegram media via QR code or phone login - YouTube, Instagram, TikTok, X, Reddit, Twitch, Pinterest, Vimeo, Bluesky natively - 1000+ more sites via yt-dlp fallback - FFmpeg conversion with GPU acceleration - Real-time progress, batch downloads, clipboard detection No browser extensions. No web apps. No subscriptions. Built with Tauri and Rust, so it's fast and tiny. Windows, macOS, Linux. 100% open source on GitHub. GPL-3.0.

@InTheAssembly @grok So ideally what companies should one invest in to ride the next wave? RAM? What?

A 25 year old just turned $225 million into $5.5 billion in 12 months. Here’s exactly what he bought. Leopold Aschenbrenner got fired from OpenAI in April 2024. He spent the next few months writing a 165-page thesis predicting AGI by 2027. Then he launched a fund and put his money where his thesis was. He bought zero Nvidia. Zero Microsoft. Zero Google. Zero Amazon. He bought what AI actually runs on. Bloom Energy (BE), power infrastructure for data centers. Up 1,422% in one year. Lumentum (LITE), optical components that move data between chips. Up 1,331%. Sandisk (SNDK), storage. Up 3,130%. CoreWeave (CRWV), GPU cloud infrastructure. Up 166%. Iris Energy (IREN), AI computing and data centers. Up 583%. The thesis was simple: every AI company needs energy, bandwidth, storage, and compute. Nobody was buying those. Everyone was buying the AI companies themselves. He was right. His fund now manages $6 billion. Backed by Patrick and John Collison of Stripe and former GitHub CEO Nat Friedman. I’m adding this to my watchlist. Every time he files a new 13F, we will break it down here. Turn on notifications so you don’t miss the alert, this is VERY important. Many people will wish they followed us sooner.

$200 to $1,440 a year saved on your Claude bill from one setting nobody turns on. It's called Prompt Caching. Most users never see it because it lives in the API. When you reuse the same context across calls, Anthropic charges full price every time. Caching tells them: "I've sent this before. Don't charge me again." Reused tokens cost 90% less. A typical Skill runs on 13,000 tokens of repeated context plus 500 tokens of fresh input. Without caching, every call pays full price for all 13,500 tokens. With caching, only the 500-token input pays full price. 200 calls a day adds up to a 60% bill cut. For someone paying $200 a month, that's $1,440 saved a year. For someone running 5-7 Skills on a Business Brain, it's $4,000-$6,000 a year. The setting has been live since November 2024. The people who flipped it then are paying 30% of what everyone else does today. That gap compounds every month it stays open.

Major upgrade to 𝕏 advertising

GTA 6 is about to create more millionaires than crypto has ever done GTA 6 drops in a month 98.89% of people will just play it. Here is how the other 1.11% will make life-changing money before the first week is over. THE MATH MOST PEOPLE WILL IGNORE 0.01% will build tools and make $50,000 or more. 0.1% will run servers at $5,000 a month. 1% will stream and cover rent. 98.89% will just play. Be at least 0.1%. With Claude Code it is not even hard. OPPORTUNITY 1 — SELL FIVEM SCRIPTS WITH ZERO CODING EXPERIENCE Claude writes Lua now. Server owners pay $50 to $389 per script on the Cfx Marketplace. Developers on Tebex report averaging over €5,000 a month within 90 days of launching. You do not need to know how to code. You need to know what server owners are desperate for right now. Custom job systems. Economy balancers. UI panels. Vehicle systems. Whitelist managers. 1 script per week for 7 months is 30 products. If each one sells 10 copies at $100 average that is $30,000. From a game you were going to play anyway. OPPORTUNITY 2 — RUN A PAID RP SERVER AS A SUBSCRIPTION BUSINESS This is the one that sounds fake until you do the math. 50 members at $15 a month is $750. 100 members at $20 a month is $2,000. 200 members at $20 a month is $4,000. 500 members at $25 a month is $12,500. Every month. Recurring. The top servers already have waitlists. People paying to get onto a list just to pay again when a spot opens. Claude builds every script you need. Jobs. Economy. Housing. Factions. Police systems. You are not a developer. You are running a private club where members pay to stay. Then take your server clips and run them through an AI UGC engine. Shorts. Reels. TikToks. Nearly free user acquisition from people who were already watching GTA content and dying to play. OPPORTUNITY 3 — AI POWERED NPC PACKS FOR SERVER OWNERS RP servers live or die on immersion. Right now most NPCs are lifeless markers on a map. Connect Claude API to in-game NPCs and suddenly shop owners haggle with players. Cops interrogate with real dialogue. Quest givers remember your backstory. Bartenders gossip about other players' crimes. No server has this yet. Package it as a plug-and-play script at $200 to $500 per server. 100 servers and the math speaks for itself. OPPORTUNITY 4 — THE $240M CREATOR ECONOMY NOBODY IS POSITIONING FOR Rockstar acquired FiveM in 2023. Launched a paid marketplace in January 2026. Currently hiring 4 Creator Platform roles. They are building the Roblox of GTA. Roblox paid creators $1 billion in 2025. The top 10 averaged $33.9 million each. GTA 6's player base is older, richer, and already spent $8.6 billion on GTA Online. The creator cut of that $8.6 billion was zero. Because there was no creator economy. That changes with GTA 6. Even if only 100,000 creators show up and it matches Roblox payouts that is $10,000 per creator on average. Top 1% will clear $500,000 or more. For making content inside a video game. THE WINDOW IS 6 MONTHS 6 months from now every niche will be taken. Right now most of them are completely empty. The people who move this week will own categories that thousands of people will be competing for after launch. The people who wait will spend next year wondering why the slots were already full when they showed up. This is the rare opportunity where demand is guaranteed. The only variable is whether you act before the crowd does. Follow @cyrilXBT for the exact Claude Code workflows, FiveM script templates, and GTA 6 monetization systems I am building right now before everyone else catches on.

someone just open-sourced an entire AI company. 147 agents. 12 departments. engineering, design, marketing, sales, finance, QA, support. each agent has a role, a workflow, deliverables. not a chatbot. a team. claude code, cursor, copilot, gemini cli, windsurf. 1 command to deploy everything. started as a reddit thread. 88,000 stars. 14,000 forks later. MIT. free. yours. this should cost $50,000/year

The man who killed the $10,000 GPU myth. He did it alone, from Bulgaria, with one C file. 🤯 >Meet Georgi Gerganov. >Bulgarian developer. Nobody had heard of him. >In March 2023, Meta’s LLaMA model leaked online >Within days he wrote a single C file >Called it llama.cpp >It ran a full AI model on a MacBook. No GPU. No cloud. >The entire AI industry said you needed $10,000 GPUs to run LLMs 🔥 >He proved you didn’t. On a laptop. Alone. >Also built whisper.cpp ~ same thing for voice AI > His code is the foundation of Ollama, LM Studio, and GPT4All >107,000+ GitHub stars. Fastest open-source AI project to hit 100K ever. 🚀 >In 2026 Hugging Face hired his entire team >Still ships code. Still open source. Still free. Every time you run AI locally, you’re running his work. Absolute Legend 🐐

YouTube Premium just raised prices. $15.99/month. Up from $13.99. The family plan is now $26.99/month. That is $323 a year. To remove ads from a website. YouTube Music: $11.99/month. $144 a year. To listen to songs without ads. Every video you watch is tracked. Every search is logged. Every pause, every rewind, every rabbit hole at 2 AM. All of it fed into a profile that advertisers pay to access. You are not the customer. You are the product. You always were. There is an open source tool that strips every ad, every tracker, and every account requirement from YouTube. Same videos. Same creators. None of the surveillance. It is called Invidious. 18,900+ stars on GitHub. Here is what it does: → No ads. None. Ever. Pre-roll, mid-roll, banner, sponsored — all gone. → No Google account required. Subscribe to channels anonymously. → No tracking. No cookies. No fingerprinting. No watch history sent to Google. → No algorithm deciding what you should watch next. → SponsorBlock integration.

Any quality. Any format. → RSS feeds for every channel. Subscribe in your reader. → Reddit comments shown alongside videos. → No JavaScript required. Works on any browser. → Self-host your own instance on any old laptop. Here's the wildest part: YouTube sent the developers a cease-and-desist letter on June 9, 2023. They told them to shut down within 7 days. Invidious said no. Three years later, they are still shipping. Last commit: 14 hours ago. Google has spent three years trying to block, sue, and bury this project. They have failed. The repository keeps growing. The code keeps shipping. The community keeps coding. Every commit is a middle finger to the ad industrial complex. YouTube Premium Individual: $15.99/month. $192/year. YouTube Premium Family: $26.99/month. $323/year. YouTube Music: $11.99/month. $144/year. Invidious: $0. Forever. No ads. No tracking. No account. No subscription. 269 contributors. 33 releases. 2,100+ forks. Built in Crystal. Battle-tested since 2018. AGPL-3.0 licensed. The license Google cannot kill. Your videos. Your privacy. Your choice. 100% Open Source. (Link in the comments)

Windows has been missing basic features for 30 years. Mac users have had Spotlight, Quick Look, and proper window snapping for over a decade. Windows users have been downloading sketchy third-party tools for every single one. Microsoft knows your Start Menu shows Bing ads. Microsoft knows your search bar opens Edge when Chrome is your default. Microsoft knows you cannot rename 200 files at once. Microsoft knows "this file is in use" never tells you which program. Microsoft knows you cannot extract text from a screenshot. Microsoft's own engineers got tired of knowing. So they built 30+ utilities that fix everything Windows got wrong. Then they put it on GitHub instead of putting it in the operating system. They just never told anyone. A billion people use Windows every day. And they all just... live with it. It is called PowerToys. 132,500+ stars. Built by Microsoft. Maintained by Microsoft. MIT licensed. Shipped v0.99.1 yesterday. Still not in Windows. Not a third-party hack. Not some sketchy utility pack. Microsoft's own engineers, on Microsoft's own GitHub. Here is what is missing from your operating system: → Command Palette. Spotlight for Windows. One shortcut. Launch anything. → PowerToys Run. Alt+Space. Search apps, files, math, the web. No Bing ads. No Edge hijack. → FancyZones. Drag any window into custom screen zones. Any layout you want. → PowerRename. Rename 500 files at once. Search-and-replace or regex. → Text Extractor. Draw a box around any text on your screen. Even inside images. Even inside videos. OCR built in. → File Locksmith. Right-click any locked file. See exactly which program is locking it. Kill the lock. → Color Picker. One shortcut. Click anywhere. HEX, RGB, HSL. → Image Resizer. Right-click. Resize. Batch entire folders. No Photoshop. → Mouse Without Borders. One mouse and keyboard across 4 computers. → Keyboard Manager. Remap any key to any other key. → Peek. Press Space on any file. Preview instantly. Quick Look for Windows. → Always on Top. Pin any window above all others. One shortcut. → Awake. Keep your screen on without touching power settings. → Crop and Lock. Crop any window into a pinned thumbnail. That's 14. There are 16 more. Here's the wildest part: Microsoft built every one of these. Microsoft's own engineers maintain them. Microsoft shipped a release yesterday. None of it ships with Windows. A billion people have been living with a half-finished operating system. The fixes exist. Microsoft made them. And hid them on GitHub. 132,500+ stars. 30+ utilities. 400+ contributors. MIT licensed. Works on Windows 10 and 11. Install in one command: winget install Microsoft.PowerToys Your Windows. Finally complete. 100% Open Source. (Link in the comments)

🇯🇵A Japanese developer built an app that puts a fat cat on your screen and forces you to take a break Silicon Valley spent billions on wellness platforms, mindfulness subscriptions, and digital detox retreats A guy in Japan said: fat cat, problem solved

@RyanSAdams Bye bye @claudeai ✌️

AI KYC is here. New claude subscribers asked for gov ID & photo. Not even a regulatory requirement - Anthropic just doing it because they want to. But regulatory is coming Next up will be laws: No AI without gov-issued ID All AI use tracked to individual - no private AI

Vercel charges $20/seat/month. Netlify charges $20/month. Heroku killed its free tier entirely. And if you go over your bandwidth? Surprise bills. Sometimes thousands of dollars. There is an open-source alternative to all three. For $0. It is called Coolify. 53,000+ stars on GitHub. You install it on any server you own. A $5 VPS. A Raspberry Pi. An old laptop. Anything with SSH. Then you deploy everything: - Static sites - Full-stack apps - Databases - APIs - 280+ one-click services (WordPress, Ghost, Plausible, n8n, Supabase, and more) Here's the wildest part: It does things the paid platforms charge extra for. - Free SSL certificates, auto-renewed - Automatic database backups to S3 - Pull request preview deployments - Real-time server terminal in your browser - Push-to-deploy from GitHub, GitLab, Bitbucket - Server monitoring with Discord/Telegram/email alerts No vendor lock-in. All your configs live on your server. If you stop using Coolify, everything still runs. The $20/month you pay Vercel? That is per seat. A 5-person team pays $100-500/month depending on usage. With Coolify on a $5 Hetzner VPS, that same team pays $5/month. Total. Apache-2.0 licensed. Self-hosted. Free forever. 100% Open Source. (Link in the comments)

Someone built an API whose only job is to say no. You send it a request. It sends back a rejection. That's the entire product. It's called No-as-a-Service. NaaS. 1,000+ rejection reasons. All curated. All devastating. Here's what it returns: - "This feels like something Future Me would yell at Present Me for agreeing to." - "I only function on coffee and denial, and I'm out of coffee." - "If I agree, I’d need to clone myself. And I don’t trust him." - "I have a personal policy of saying no on days ending in 'y'." Need to reject a meeting? NaaS. Need to decline a date? NaaS. Need to say no to your boss without getting fired? Believe it or not, also NaaS. Here's the wildest part: Developers loved it so much they built an entire ecosystem around it. - A Slack bot that responds with /no in team channels - A Signal bot for automated rejections - An iOS app on the App Store called "Nope App" - An Android app that gives you excuses on demand - A Raycast extension so you can reject things from your launcher - An MCP plugin so your AI assistant says no for you 6,500+ developers starred a joke. 408 people forked it to build their own ways to say no. The license reads: "MIT -- do whatever, just don't say yes when you should say no." The most honest software ever written. Its only job is to say no. And it does it beautifully. 100% Open Source. (Link in the comments)

Someone built a free, open-source CleanMyMac alternative with zero telemetry. And it is fully native SwiftUI. It's called PureMac. And it does everything CleanMyMac does for the most common cleaning tasks. For $0. Here is the problem with every existing macOS cleaner: CleanMyMac: $39.99 per year. Tracks your usage. Sends data home. MacCleaner Pro: $29.99 one time. Closed source. DiskDiag: Limited. Not automated. Every other option: ads, telemetry, or a subscription. PureMac has none of that. Here is what it handles: -> Xcode derived data, archives, and simulators (devs: you know how fast this grows) -> Homebrew cache that bloats silently over months -> System caches and logs that macOS never cleans itself -> Scheduled automatic cleaning. Set it once. Forget it. Built entirely in native SwiftUI. Menu bar integration. Progress indicators. Dedicated settings and scheduling views. No AppKit hacks. No Electron. A real Mac app. What you will never find in it: -> Zero telemetry -> Zero analytics -> Zero subscriptions -> Zero data collection The developer built this because every available tool either charged money or phoned home. So he built one that does neither. MIT License. Open Source. Free.

@chefsevenn Go to the hospital and pay peoples bills. Cause hospital broke is real.

You’re given $2m. You have 20 minutes to spend it. You can’t spend it on cars, airplanes, yacht or a house. You can’t spend it on golds or diamonds either. What will you buy?
