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

Practice system design by submitting architectures and experiencing AI-triggered production incidents.

I built an AI-augmented system design practice tool that triggers a live production incident when you submit your design - not just a critique Every system design prep resource I used was static — read a diagram, read the tradeoffs, move to the next one. Nothing ever pushed back on what I actually built. So I built ChaosBench . You design a system on a canvas — drag components, wire them up — and when you submit it, an LLM (Gemini) finds the actual weak point in your specific design and

Free calculators for DIY home projects like woodworking, decks, concrete, and drywall.
u/CaboWabo55 · Reddit
Built a DIY calculator site in a weekend — betting on "boring tools" over content After my last project (an AI debate platform) got rejected by AdSense for "low value content," I went the opposite direction: no content treadmill, no AI features, no backend. Just genuinely useful calculators. studandslab.com — 10 free calculators for woodworking and home projects (board feet, stair stringers, concrete, drywall). Everything runs client-side, so hosting is free and every visitor costs me $0.
