Building Bluesky: a Distributed Social Network (Real-World Engineering Challenges)
[...] Today, the Personal Data Servers are bare-metal servers hosted by cloud infrastructure vendor, Vultr. Bluesky currently operates 20 and shards them so that each PDS supports about 300,000 users. [...]
[...] **Owning your own infrastructure instead of using the cloud seems a rational choice.** Bluesky found large savings by moving off AWS once they could forecast the type of load they needed. Jake Gold, the engineer driving this transition, has been vocal about how cloud providers have become more expensive than many people realize. Speaking on the podcast, Last Week in AWS, he said:
> “With the original vision of AWS I first started using in 2006, or whenever launched, they said they would lower your bill every so often, as Moore’s law makes their bill lower. And that kind of happened a little bit here and there, but it hasn’t happened to the same degree as I think we all hoped it would.” [...]

How a UK treaty could spell the end of the .io domain
英国的条约为什么意味着.io域名的终结
[...]
Last week, the British government announced that it has agreed to give up ownership of the Chagos Islands, a territory in the Indian Ocean it has controlled since 1814 — relinquishing the .io domain with it.
上周，英国政府宣布同意放弃查戈斯群岛的所有权，查戈斯群岛是英国自1814年以来控制的印度洋领土，这项决定也导致英国政府同时放弃了.io域名。
now, the UK’s finalized agreement will make the Chagos Islands part of Mauritius — a move Chagossians say the government didn’t even consult them on. With this change, the British Indian Ocean Territory is no more, calling into question the future of the .io domain.
现在，英国最终达成的协议将使查戈斯群岛成为毛里求斯的一部分 — 查戈斯人说，政府甚至没有征求他们的意见。随着这一变化，英属印度洋领土不再存在，对.io域名的未来提出了质疑。

注: 毛里求斯的国家顶级域名是 .mu

Potential Ozone Depletion From Satellite Demise During Atmospheric Reentry in the Era of Mega‐Constellations
With ongoing plans for many constellations of small satellites, the number of objects orbiting the Earth is expected to continue increasing in the foreseeable future. At the end of service life, satellites are disposed into the atmosphere, burning up during the process and generating aluminum oxides, which are known to accelerate ozone depletion. The environmental impacts from the reentry of satellites are currently poorly understood. This paper investigates the oxidation process of the satellite's aluminum content during atmospheric reentry utilizing atomic-scale molecular dynamics simulations. We find that the population of reentering satellites in 2022 caused a 29.5% increase of aluminum in the atmosphere above the natural level, resulting in around 17 metric tons of aluminum oxides injected into the mesosphere. The byproducts generated by the reentry of satellites in a future scenario where mega-constellations come to fruition can reach over 360 metric tons per year. As aluminum oxide nanoparticles may remain in the atmosphere for decades, they can cause significant ozone depletion.

EU chat control law proposes scanning your messages — even encrypted ones - The Verge
> The proposal, which is aimed at preventing child sexual abuse material, would essentially break encryption.
[...]
As if this doesn’t seem wild enough, the proposed legislation appears to endorse and reject end-to-end encryption at the same time. At first, it highlights how end-to-end encryption “is a necessary means of protecting fundamental rights” but then goes on to say that encrypted messaging services could “inadvertently become secure zones where child sexual abuse material can be shared or disseminated.”

亚马逊收购印度视频流媒体服务 MX Player
一位知情人士告诉 TechCrunch，两家公司于周三晚间就该交易达成了最终协议。消息人士称，这笔交易对 MX Player 的估值不到 1 亿美元，远低于这家流媒体公司筹集最后一笔资金时的 5 亿美元估值。
亚马逊正在收购 MX Player 的部分资产，但不是整个公司，腾讯也是该公司的支持者之一。交易完成后，MX Player 的许多高管将转移到亚马逊。
亚马逊发言人证实，在本文发表后，亚马逊已同意购买 MX Player 的部分资产。
Times Internet 于 2018 年以 1.4 亿美元收购了 MX Player。这款起源于韩国的应用程序因其独特的本地视频播放功能而在印度广受欢迎。此功能使该应用程序能够支持多种视频文件格式，使其与发展中市场流行的经济实惠的 Android 智能手机高度兼容。
收购后，Times Internet 采取了战略举措，将 MX Player 从本地视频播放应用程序转变为综合视频流媒体平台。该公司投资在该应用程序中添加各种授权和原创内容，包括电视节目、电影和游戏，以满足印度以及英国和美国等许多国际市场日益增长的在线娱乐需求。

Secrets from the Algorithm: Google Search’s Internal Engineering Documentation Has Leaked
...
An important thing we can all take away from this is: SEOs know what they are doing. After years of being told we’re wrong it’s good to see behind the curtain and find out we have been right all along. And, while there are interesting nuances of how Google works in these documents there is nothing that is going to make dramatically change course in how I strategically do SEO.
For those that dig in, these documents will primarily serve to validate what seasoned SEOs have long advocated. Understand your audience, identify what they want, make the best thing possible that aligns with that, make it technically accessible, and promote it until it ranks.
To everyone in SEO that has been unsure of what they are doing, keep testing, keep learning, and keep growing businesses. Google can’t do what they do without us.

TL;DR KEY TAKEAWAYS:
- Google claimed they don't use a "domain authority" metric, but the docs show they totally do - it's called "siteAuthority."
- G said clicks don't affect rankings, but there's a whole system called "NavBoost" that uses click data to change search results.
- Google denied having a "sandbox" that holds back new sites, but yep, the docs confirm it exists.
- G assured us Chrome data isn't used for ranking, but surprise! It is.
- The number and diversity of your backlinks still matter a lot.
- Having authors with expertise and authority helps.
- Putting keywords in your title tag and matching search queries is important.
- Google tracks the dates on your pages to determine freshness.
- A lot of long-held SEO theories have been validated, so trust your instincts.
- Creating great content and promoting it well is still the best approach.
- We should experiment more to see what works, rather than just listening to what Google says.
