玩币安 Alpha 刚好经历一个完整周期，净利润 $77.74，感觉还行了。😀
抢门槛为 200 积分的空投，好几次没抢到，差点放弃。还是门槛高一些的好~😭
之前看到一个说法，任何一个门槛，都会阻挡很多人。没门槛的机会，很快就会被踩成坑。有门槛的机会，可持续性好很多。😎

最近用 nostr 发现两个不太好的地方。
- 通知比较混乱，不够准确，也不够实时。
- 评论结构的处理。现在支持「对评论的评论」，但展示不够友好。打开主帖，只能看到少量「对主帖的评论」，要继续点开评论才能看到层层嵌套的回复。这样导致信息很分散，即使讨论很热烈，也难以感受到氛围。相比之下，我更喜欢扁平或一次性展示完整评论树的方式，就像 Hacker News 那样。
#nostr
Recently, I’ve noticed two areas where nostr could be improved:
- Notifications are messy — not accurate enough and often not real-time.
- Comment structure handling. Currently, it supports “comments on comments,” but the display isn’t very user-friendly. When opening a main post, you only see a few direct replies, and need to keep clicking through to view nested responses. This makes the discussion feel sparse and fragmented, even when it’s actually lively. I’d prefer a flatter view, or better, showing the entire comment tree at once — similar to Hacker News.

我刚在 
注册了他们的新钱包服务，支持 Lightning Address（比如 @rizful.com）和我一直很喜欢的 NWC（Nostr Wallet Connect）协议。
现在我已把我的 nostr Lightning Address 设置为 yfaming@rizful.com，并在 Primal app 中通过 NWC 连接了这个钱包，整体体验很顺畅！
而且只要在 Nostr 上发帖并 AT @Rizful.com ，就可能收到他们发的 test zap 打赏～ 想试试？推荐参考这篇文档：
I just signed up for the new wallet service at
.
It supports Lightning Address (like @rizful.com) and the NWC (Nostr Wallet Connect) protocol, which I’ve always liked.
I’ve already set my nostr Lightning Address to yfaming@rizful.com
, and connected this wallet in the Primal app via NWC. The experience has been really smooth!
And here’s the fun part: if you post on Nostr and @Rizful.com, you might receive a test zap from them. Want to try it out? Check this guide:

About nostr database
I’ve been reading the `NostrDatabase` trait and its LMDB backend in rust-nostr. Storing events is simple—just put `(event_id → event)` in a KV store. The challenge is querying, since LMDB itself only supports very basic lookups.
The approach in nostr-lmdb is to build extra indexes (e.g. author+kind+created_at+id, tag+created_at+id, etc.). Queries pick the most suitable index to fetch candidate event IDs, then filter them one by one.
A few thoughts:
Indexing on a KV store is straightforward, nothing mystical.
The query logic is verbose, basically a hand-rolled rule-based optimizer. A cost-based optimizer might be a more advanced path?
NostrDatabase only supports a single filter, while the protocol allows multiple filters (OR across filters). So a relay must merge results manually.

关于 nostr database
最近读了 rust-nostr 里的 NostrDatabase trait 及其 lmdb 实现。存储部分很直观，以 event_id 为 key 存储 event。难点在查询：因为 lmdb 只是 KV 数据库，它本身不支持复杂查询。
nostr-lmdb 的做法，是在存储 event 的同时，额外维护多组索引（比如 author+kind+created_at+id，tag+created_at+id 等）。查询时，先挑合适的索引定位可能的 event id，再逐一过滤。
这种实现让我有几点感受：
原来在 KV 底层上建索引可以这么做，其实没什么玄妙。
查询逻辑比较冗长，感觉像是手工实现了一个 rule-based 优化器。如果更复杂，或许需要 cost-based 优化？
目前 NostrDatabase 只支持单一 filter，而协议里 filter 之间是 OR 关系。如果要做 relay，还得额外处理多个 filter 的合并。
哭了，连续三次没抢到币安 Alpha 空投，竞争这么激烈的吗？！😂
直接在 nginx 配置里设置 NIP-05 验证，不得不说 nginx 真挺强大，我了解的太少了（方案是 ChatGPT 给的）。
手速太慢，错失一次币安 Alpha 空投 😭
dioxus 看起来不错，能用 Rust 同时写 UI 和业务逻辑，对我来说挺有吸引力的。这是它相较于 tauri 的最大优势。
值得关注的是 dioxus 的 UI 组件功能是否足够强大。毕竟，目前用前端技术写 UI（HTML/CSS/JavaScript）几乎是最优解，有 React、Vue、Tailwind CSS 等成熟且强大的库可用。如果 dioxus 的 UI 能达到类似的水平，那它就更有吸引力了。

今天币安 Alpha 没有空投，伤心中
币安 Alpha 刷到了 240 分，看今天能不能领到空投吧！
刚估算了一下 nostr 数据的存储成本（单纯存，不做复杂查询/搜索），大概在 $20 左右，还算能接受。
那问题来了：nostr 数据有没有商业价值？至少能当 AI 的训练语料吧。要是真能卖出几份，光靠这就能覆盖运营成本了。
数据量（event & post）参考自 nostr.band。
Just estimated the storage cost for nostr data (pure storage, no complex queries/search).
Turns out it’s around $20 — pretty affordable.
But here’s the question: does nostr data have commercial value?
At the very least, it could serve as AI training corpus. If I can sell it a few times, that alone might cover the operating cost.
Event & post counts are based on nostr.band.
