相对其他的软件来说,电报 Telegram 更安全点,下面是电报 CEO 在他自己的电报频道里发过的一个帖子:
"A story shared (https://x.com/jack/status/1787895769183268948) by Jack Dorsey, the founder of Twitter, uncovered that the current leaders of Signal, an allegedly “secure” messaging app, are activists used by the US state department (https://www.city-journal.org/article/signals-katherine-maher-problem) for regime change abroad
The US government spent $3M to build Signal’s encryption, and today the exact same encryption is implemented in WhatsApp, Facebook Messenger, Google Messages and even Skype. It looks almost as if big tech in the US is not allowed to build its own encryption protocols that would be independent of government interference
An alarming number of important people I’ve spoken to remarked that their “private” Signal messages had been exploited against them in US courts or media. But whenever somebody raises doubt about their encryption, Signal’s typical response is “we are open source so anyone can verify that everything is all right”. That, however, is a trick
Unlike Telegram, Signal doesn’t allow researchers to make sure that their GitHub code is the same code that is used in the Signal app run on users’ iPhones. Signal refused to add reproducible builds (https://github.com/signalapp/Signal-iOS/issues/641) for iOS, closing a GitHub request from the community. And WhatsApp doesn’t even publish the code of its apps, so all their talk about “privacy” is an even more obvious circus trick
Telegram is the only massively popular messaging service that allows everyone to make sure (https://core.telegram.org/reproducible-builds) that all of its apps indeed use the same open source code that is published on Github. For the past ten years, Telegram Secret Chats have remained the only popular method of communication that is verifiably private"
所谓资产配置,就是资金在组合中的不同投资工具中的配置比例,不做任何投资的流动性现金,也被列成投资工具的一种。Gary Brinson等人的论文发表到今天已经有20多年,这20多年中,长期投资的大型基金里面,耶鲁大学基金会的David F. Swensen,便在在农地一项上长期配置大比重资产而跑赢所有大型基金。这一投资方法,接近铁血宰相俾斯麦的投资理念。再次用实例说明资产配置的重要性。
对于小投资者来说,在牛市中,容易受市场诱惑,常过度投资,没有保留足够现金用于开支,又或者对熊市长度预期不足,在牛熊转折之后,长期熊市之时,往往也正是市面资金紧缺之时,公司盈利下降,薪水不升反降,有些同时碰上家庭成员、亲戚或者其他需要开支、借款,所保留现金不足,出现现金流缺乏问题,在股票低位时,不能买入,反而被迫卖出以应付生活开支或其他需求。不能像养老基金等长期买入,长线投资。另外,资产配置一项,类似David F. Swensen的投资方式,一来要精熟于农地这项投资,二来金额巨大,回报周期极长。非小投资者资金所能及。
43、【收益与资产配置之关系】根据 Ibboston 和 Kaplan 于2000年发表的研究,长期来看,基金收益的变化中,有90%来源于资产配置的变化。斯文森在《机构创新之路》第4章中,提出质疑意见:他举一个例子,假设一个组合中只包含一只股票,同时,采用 buy and hold 的办法,长期持有。那么,长期下,收益便只与股票的选择有关。而与资产配置无关。
