Is vibe coding criticism fair? A lot of the criticism of vibe coding is fair. Too many projects look good in a demo then fall apart in production — weak security, missing edge cases, code nobody understands later. One of the biggest gaps is testing (or the total lack of it). I took both automated and manual testing seriously while building Brainary. Ended up with a testing-to-code ratio of about 1 to less than 3, plus a lot of hands-on checking. I think it turned out solid because of that.

经过实测,keystone的骰子生成助记词和 经历了coldcard被盗事件,我就想用完全自己收集熵,来生成助记词,并且要求完全可验证。所有冷钱包和app 钱包都说自己的随机数是安全的,用最高级的随机数生成器,但是我无法验证,就像coldcard使用了安全芯片,但是在最终生成助记词的时候却没有调用该芯片,所以我就想找一种能自我验证的随机数生成方式,后来看到了keystone的推文,keystone支持骰子生成,正好我有keystone钱包。 但是下一个问题,我怎么验证keystone使用骰子生成的助记词是安全的,怎么证明它用的熵就是我提供给它的那一个?之前研究过 经过实测,keystone的骰子生成助记词和 据说trust wallet也支持该功能,明天找时间再验证一下trust wallet @KeystoneWallet @KeystoneCN

Like everyone on HN, I love nothing more than to (re)read my own comments. Getting my intuition that I am among the smartest, most humble, highest quality commenters on here confirmed by an LLM so capable that the US government had to temporarily export restrict it [0] seemed only natural. Having had my perfection confirmed, I decided to share this joy with you as I had a few percent usage left before a reset. I took a few prompts, then did a review of the output which resulted in Selbstbild, a BYOK (Anthropic / OpenRouter) web app that gives you a summary and assessment of your public comments by one of our machine Gods, including Fable 5 (provided your can afford that luxury at API pricing). In all seriousness, I have, for a long time, used my own comments on social media (including HN) as part of a personal needle-in-haystack test, simply because I do know my somewhat peculiar style and what I tend to write, but also because I can sometimes write in a slightly confusing manner, ma

Building made me switch from Claude Code to Codex. Claude’s token usage was too expensive for my workflow. GPT-5.6 Sol + Codex lets me focus on building instead of watching usage limits. Loving it so far! 🚀 @OpenAI @thsottiaux
