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

dzzz.ai over 90 tools in one website privacy focus Hey r/SideProject , I kept uploading private invoices and contracts to random "free PDF tool" sites just to compress a file. Eventually it occurred to me that the browser can do this locally — so I built dzzz.ai : over 90 tools that run entirely on your device. PDF compress/merge, video trim and conversion, background removal, HEIC→JPG, document scanning with your camera, audio transcription, CSV cleanup. All WebAssembly — ffmpeg, Ghost

AI-powered coding agent template supporting Claude Code, OpenAI Codex CLI, Cursor CLI, and opencode with Vercel Sandbox

Had a good chat with @AmirKodro, founder of vibe coding tool about how I'm a bit surprised we don't yet have something of a traditional business org chart with silo'd AI agent "employees". Lo and behold, today I come across @coderblock, which does exactly that! What do you think @AmirKodro?

Share code and text securely with end-to-end encryption and persistent AI assistant memory.
u/clausyn · Reddit
I built Pastepile because I was tired of re-explaining the same context to Claude and Cursor I originally built Pastepile as a fast way to share code, logs, configs, and text without creating an account. While using AI coding tools, I kept running into another problem: every new session meant explaining the same architecture, decisions, debugging history, and project context all over again. So I added an MCP server that lets Claude, Cursor, Windsurf, VS Code, and other MCP clients save us

Open-source remote control for Claude Code and Codex on iOS, Android, and web.

Few days ago Happy had a birthday. Tried to refresh one of the most neglected part of it: our Happy Website: also i built a new harness called “rig”. i started to use at work recently instead of codex/claude code and i liked how it does work. i want to share this with everyone. it is a codex and cause code reimplemented using Pi, but keeping native prompts and expanded a little for uniformity (like added workflows to codex yay!). when something new released that is worthy of porting - i ask Sol to mim for prompts or read sources directly and i can have a feature within an hour. why this is needed? i was constantly blocked by the needing of integrating a lot of models together, which each has their own harness or many doesn’t have any, but i didn’t want to go too far from native and don’t like the idea of extensions - i want experience to be the same everywhere. i think configuration > extensions. more soon
