Its been 4 months building my exam prep site, still 0 customers. Unable to figure out the next step. So I've been building for the last 4 months. Practice exams + an AI tutor for AWS certifications. I'm solo, based in India, launched the website in April. Since launch I was getting very few visitors a week and zero sales. I kept thinking the product wasn't good enough , so I just kept adding stuff. More questions, more certifications, more features. But sadly nothing changed.

Building an AI search engine instead of another chatbot I've been building an AI-powered search engine over the last few months as a side project. The idea came from noticing that I'd often Google something, open several tabs, then copy everything into an AI tool to get a useful answer. It felt like there was an unnecessary step in the process. The goal isn't to replace the web, but to make research faster by generating structured answers with citations and giving users the option to see

Building CodeBull. A platform where you build trading bots with Python or visual blocks, backtest them on real-world market data, and compete against other users’ strategies. Zero risk. Just learn trading by building.

Instead of asking "what should I learn next?", I built a tool that diagnoses your actual gaps and tells you One pattern I keep seeing here (and had myself): you're learning a field - say backend development or ML - and at some point you don't know what you don't know. You've done tutorials, watched videos, maybe built some projects. But you can't tell if you actually have real understanding or just surface-level familiarity. I built a free tool called Cascade AI that tries to solve this.

🎁 看直播，玩预测，赢周边 🎁 长鑫还在大 A 路演，HL 那边“股价”已经炒翻天！ 是全球价格发现，还是没有股票的链上赌场？ 你认可链上 Pre-IPO 给未上市公司提前定价吗？ 近期，长鑫科技推进科创板 IPO，A 股发行价最终确定为 8.66 元。就在长鑫进行路演和申购期间， 已经通过 Hyperliquid 的 HIP-3 框架上线了 xyz:CXMT Pre-IPO 永续合约。 这个合约以 5 美元作为初始参考价，一度冲到 8.64 美元。看起来只是把 8.66 元换成了 8.64 美元，实际折算下来，链上价格已经接近 A 股发行价的 7 倍。 但需要注意，Hyperliquid 上交易的并不是长鑫股票。 持有 xyz:CXMT，没有 IPO 配售权、分红权或投票权，也不能在长鑫上市后兑换成真实 A 股。交易者只是在使用 USDC 和最高 5 倍杠杆，对“一股长鑫上市后值多少钱”进行做多或做空。 Hyperliquid 上的长鑫合约，是让全球资金提前参与中国硬科技定价？ 还是在没有股票、没有交割的情况下，制造一场高杠杆价格游戏？ SpaceX 没拿到股票，长鑫干脆不交股票。 这是链上 Pre-IPO 的产品进化？ 还是“金融平权”叙事的一次退化？ 本期 非小号K博士侃币 深度开聊： 《长鑫还在大 A 路演，HL 那边“股价”已经炒翻天！是价格发现还是链上赌场？你认可链上 Pre-IPO 给未上市公司提前定价吗？》 ⏰ 时间：2026年7月20日（周一）21:30 (UTC+8) 🎥 直播入口： 📡 同步直播平台：非小号 | X | 币安广场 | 火币Live | 热币Live | Gate Live | YouTube | TikTok | Telegram | pumpkin | sidekick | Debox 请锁定以上任一 TalkingWeb3/非小号 官方频道，或关注 TG 获取全部直播链接！ 本期主持人： 👨‍🏫Ken博士 @ken_fxh - 非小号掌门人 👨‍🏫十三亿.Luffy @xiayi_web3 - luffy社区 👨‍🏫林野 @yu56413 常驻嘉宾： 👑 非小号 @fxh_crypto 👑 方宏进 @fang_herbert 👑 Dr

Okay. I created a course on a website I vibe coded. It's for sale, but I'm going to give it to you for free. I'll keep uploading new lectures everyday. Currently, I've uploaded 2 videos. Once you register, tell me and send me the email you used in registering, so I can unlock the video for you.

做了一个 AI 职业风险地图，直观看看各个国家各个行业的工作受到 AI 冲击的程度 前段时间自己频繁搜索 AI 会如何影响我从事的职业，我周边的人从事的职业，然后又开始搜索哪些职业很难被 ai 代替。搜到的信息很零散，几乎没有数据完整、可视化好的网站。 所以我做了一个可视化网站： ## AI Job Risk Map https://aijobriskmap.com 网站使用 Treemap 展示不同职业的 AI 风险。每个方块代表一个职业： - 方块大小表示职业规模 - 颜色表示 AI 风险等级 - 可以按国家查看职业分布 - 可以比较不同职业和职业类别 - 支持查看具体职业的风险数据 目前主要覆盖美国、英国、加拿大、澳大利亚、新西兰及欧洲、亚洲的多个国家。风险评分关注的是职业中的任务有多少可能被 AI 自动化或显著改变，并不等同于预测某个职业会彻底消失。 这个项目仍在完善中，尤其希望听听大家对下面几个问题的意见： - 风险地图是否容易理解？ - 你更关心“职业被替代”，还是“职业会如何被 AI 改变”？ - 除了风险、薪资和就业规模，

building in public: a tool to practice real work instead of courses saw so many people finishing courses and collecting certificates like they're collecting pokemon cards. So we built something that closes the gap between "i finished the course" and "i can actually do the work" it's tasklearn.app , you get real industry tasks, you attempt them, you see how far you actually get. no videos, no tutorials , just the task itself and ai feedback on what you did. learning th
