几天没来nostr,说说我的看法,nostr上的讨论总能引发思考。
科技没有对错也没有正义和邪恶。
宏观上科技对人类种群利远远大于弊。
比如抗生素并不是一出现就延长了人类平均寿命二十年,最初想吃都吃不上的时候也谈不上滥用,正是科技发展使其大规模使用才延长了平均寿命,人们现在抱怨滥用开始影响平均寿命,本质是对进一步延长平均寿命的期望。
科幻里经常有文明瓶颈期反科技思潮的描述,宗教神学玄学充斥其中。实际并不是科技导致了文明的瓶颈,而是文明自身发展到了科技的瓶颈,我们恰恰需要新的科技去给文明提供新的发展空间。
断章取义来说如果塔勒布是这么说的,我只能说那是他的局限。

自由主义的定义很宽泛,看具体指哪类型了。
很好的问题!社会和经济本身就是复杂系统的研究对象,自然也影响对其看法。我认为容易导向的倾向有几个方面:
1、区别对待系统与个人,比如非常多人会用个人道德观去评价和要求组织,这种认知没什么意义。
2、理性认识个人能动性的有限性,敬畏系统的力量,类似雷军说的顺势而为,这往往引起对集体主义行为比如经济宏观调控有效性的质疑。
3、对不可预测的系统转换点的担忧。
4、注重具体过程和过程上下文,反对经验主义。
Santa Fe研究人员的介绍里往往有一个特殊共同点——阿西莫夫的《基地》,在其中更容易体会我说的几点,心理史学本质就是社会复杂系统演化研究。

不敢,都是迷途小学童。
系统工程通常被认为是系统科学具体工程化的方法论,不明白为什么国内搞成了研究学科。
有一本书可以看看,但不确定有没有中文版。Complexity: A Guided Tour. Oxford University Press, 2009.
这方面最好不看中文的,复杂系统研究其实和国内部分意识形态是相悖的。
I'm happy to share that njump, after a lot of tweaks and fixes, exits the beta and is ready for production, hopefully :)
# What is njump?
Njump (https://github.com/fiatjaf/njump) is a static nostr gateway that allows you to browse profiles, notes and relays; it is an easy way to preview a resource and then open it with the preferred client.
Njump currently lives under nostr.com, you can reach it appending a nostr (NIP-19) entity (npub, nevent, naddr, etc) after the domain, nostr.com/p/{nip-19-entity}, for example:
https://nostr.com/npub180cvv07tjdrrgpa0j7j7tmnyl2yr6yr7l8j4s3evf6u64th6gkwsyjh6w6
The typical use of njump is to share a resource outside the nostr world (clients), where the nostr: schema is not (yet) active. There are several reasons to prefer njump to share a nostr resource, versus other web clients, let's see them.
## Clean, fast and solid
Pages by njump are extremely light and fast to load because there isn't any client side javascript involved; they are minimalistic with the right attention to typography, focusing the content without unecessary details. Furthermore they are cached, so sharing a page you can expect the other part will load it without any glitch in a fraction of second: the perfect tool to onboard new users!
## Good preview
Njump previews notes in a simple but effective way, including links (to other nostr resources and web), images, video, quotes, code. It is compatible with long form content so it also renders markdown. It shows the note parent, allowing to follow it up. It has custom css for printing or exporting to PDF, so it is a nice option to read long form contents offline.
## Cooperative (jump-out)
Njump is not interested into "capture" users at all, on the contrary it invites them to "jump" to the nostr resource with one of the proposed clients. It even remembers the most used one and put it on the top for fast click/tap.
## Search engine friendly (jump-in)
This is crucial: njump pages are static so search engines can index them, these means that njump can help others to discover great content on nostr, jump in and join us! Njump is the only nostr resource that has this explicit goal, if you care that a good note could be found online use njump to share it, this way you also help nostr flourish.
## Bonus: NIP-5 profiles
Now you can share your own profile with an pretty permalink: nostr.com/p/{nip-5}, example: https://nostr.com/p/fiatjaf.com
A profile shows the basic metadata infos, the used "outbox" relays (Gossip model) and the last notes.
Of course profiles are also static, fast and indexable, so start to promote your nostr presence this way!
## Bonus 2: relays
You can have a view of the last content posted to a relay using nostr.com/r/{relay-host}, example: https://nostr.com/r/nostr.wine
Some basic infos (NIP-11) are available; I hope operators will start to make them more personal and informative so users can have a way to evaluate if/when to join a relay.
## Bonus 3: Inspector tool
You know, we are all devs including our moms, so for every njump resource you can toggle the "Show more details" switch and inspect the full event's json; without installing other tools, like nak, this is probably the fastest way to obtain it.
nostr:note1qqqqq772a5jhc20ezg8dttez7jx266wj27whjpswenk6hz5h377qkug6yz 如果nostr.com这个gateway功能本地化为一个软件,nip19标识就是url,每个npub都变成了网站,现有客户端可以是类似rss阅读器的应用运行在其上,这就是真正的nostr browser了。
这种定义的浏览器没有现在客户端UI/UX的限制,可以更容易对广泛新的kind增加支持,nostr完全变成了新web的数据层。
中文的系统工程这个词其实是被滥用的,钱当年也认为系统工程不是科学,他当年主要目的其实是用于社会主义治理,我认为你想了解的其实是系统科学,复杂系统是其中一部分,但的确是最耀眼的。
我曾经的一个工作是系统工程师,其实就是总体组的😂
所以金融应用比如衍生品投资期货期权之类除非定义在合并报表的sidechain上,否则都不是未来。
以太坊是把自己搞成万能公司,啥都想干,啥都能干,但最终会啥都干不好,其实经济系统进化到现在,搞子公司才是正路,对于广泛的加密货币金融应用,智能合约不是重点,按应用sidechain才是。
银票是很好的比喻,或者银行本票也是,金融史是个圈😂
比特币是个大复式账本,闪电和ark其实都是走记账凭证trick,sidechain是走子公司合并报表的路线,cashu是出纳路线,天然要求的信任程度高,所以要求高的可以多几个经理签字,那就是fedimint,但如果两个公司出纳碰到一起容易出些问题,也就是mint之间的swap很重要,cashu用闪电作为通道swap,其实ark更适合,但ark现在还不完善。
