Hi HN, The one thing AI reliably does is generate noise. Half the tools I see launch are just machines for producing more noise across more channels. And people are starting to see this in the form of emails in their inboxes as spam filters are struggling. There used to be a useful signal in email: the effort a sender put into customizing a message was a rough proxy for how relevant it actually was. AI killed that. Now it's customized slop with the appearance of effort with none of the cost. It is painful that the open internet / open channels have been abused like this. Captchainbox applies the idea of proof-of-work to email. If a sender is willing to do a bit of work to reach you, the message is more likely to be worth your time and the sender more likely to be real. The work is a traditional captcha. You can also set a pay-to-deliver amount if you want more friction. The proceeds of the delivery payment after transaction costs go to the Internet Archive and the EFF. The tool curr

有位大兄弟制作了一个计算variational积分价值的网站,使用起来很方便: 我以市值1.5B,总积分9.3M,空投25%来计算,每分的价值是40u,1000分就是40000u 我认为这是保守估计,如果8月份variational上线了swaps和api,数据会更好看,而且以var的格局来看,空投应该不止25%,可能30%以上!

现在到底有多少人定投纳斯达克100?定投后收益怎么样? 我用 @dappOS_com 的 xBubble Coding 做了一个更直观的网站 收益预估计算: 如果你开始买纳斯达克指数基金会发现总推这方面的内容,搞得好像全世界很多人都在买这个东西。 觉得这个就是特别的主流,其实还是一个比较偏门的投资。 在 xBubble 找到了权威的数据,大概是400W左右 用人口除一下不难发现,大概就是万分之2.8,10000个人里面只有三个人在定投。 我又不是程序员,就随便描述了一下想要啥,十分钟就搞出一个能用的网站:支持切换不同指数、人民币/USDT/USDC 随便选、收集定投动态跳动的人数、年限对比表、漂亮图表、详细计算逻辑和风险提醒。 以前搞这些得配服务器、买域名、调 API、部署……头都大了。 现在 xBubble Coding 全帮你包了,真就是普通人也能 1 小时内把想法变成真产品 牛就牛在,它不是扔给你一堆代码让你自己折腾,而是端到端全搞定:界面、逻辑、数据、部署一条龙。 我这个计算器能实时算复利、自动刷新、还有表格和图表,看着就专业。 以后想加会员收费、接稳定币支付,也能继续聊着天就改。 不像别的 AI 工具只帮程序员写代码,它专门为咱们这些不会技术的个人创业者(OPC)和小团队设计的,直接卖的是能赚钱的完整生意 现在大厂的标准化产品只吃掉 20% 的市场,剩下 80% 都是各种奇奇怪怪的垂直、小众、短平快需求 xBubble Coding 帮你把技术门槛、雇人成本、试错成本全抹平了,让每一个脑子里的小想法都能快速变成能赚钱的生意。 别人还在用 AI 卷着写代码的时候,咱们已经用 xBubble Coding 把想法变成真金白银了。 用抗审查保护自己,用 SOP 降低风险,用对话式 Coding 快速增长。 这可能就是 AI 时代,普通人、小团队拿超额利润的最强基础设施
