Two new variants of 10 megabit per second Ethernet over a single twisted pair, known as 10BASE-T1S and 10BASE-T1L, were standardized in IEEE Std 802.3cg-2019. 10BASE-T1S has its origins in the automotive industry and may be useful in other short-distance applications where substantial electrical noise is present. 10BASE-T1L is a long-distance Ethernet, supporting connections up to 1 km in length. Both of these standards are finding applications implementing the Internet of things.
Linux Unified Key Setup (LUKS) or dm-verity on Linux are examples of OS-level applications that can leverage NitroTPM too.
然後支援的平台有些限制，只有 Intel 與 AMD 的平台有支援，而且還要扣掉 Xen、Mac 以及 bare metal 的機種：
At the moment, we support all Intel and AMD instance types that supports UEFI boot mode. Graviton1, Graviton2, Xen-based, Mac, and bare-metal instances are not supported.
ARM 那邊有自己的一套，不太玩 TPM 大概可以理解，Xen 大概是不想支援 (停止開發新功能之類的原因)，Mac 可能是 Apple 的硬體限制，最後的 bare metal 是因為沒辦法虛擬化？
然後這個功能不另外收費，看起來幾乎是全球性一次更新：
There is no additional cost for using NitroTPM. It is available today in all AWS Regions, including the AWS GovCloud (US) Regions, except in China.
Starlink for RVs provides the ability to pause and un-pause service at any time and is billed in one-month increments, allowing users to customize their service to their individual travel needs.
Our next generation, Graviton3 processors, deliver up to 25 percent higher performance, up to 2x higher floating-point performance, and 50 percent faster memory access based on leading-edge DDR5 memory technology compared with Graviton2 processors.
Smart speakers collect voice input that can be used to infer sensitive information about users. Given a number of egregious privacy breaches, there is a clear unmet need for greater transparency and control over data collection, sharing, and use by smart speaker platforms as well as third party skills supported on them. To bridge the gap, we build an auditing framework that leverages online advertising to measure data collection, its usage, and its sharing by the smart speaker platforms.
We evaluate our framework on the Amazon smart speaker ecosystem. Our results show that Amazon and third parties (including advertising and tracking services) collect smart speaker interaction data. We find that Amazon processes voice data to infer user interests and uses it to serve targeted ads on-platform (Echo devices) as well as off-platform (web). Smart speaker interaction leads to as much as 30X higher ad bids from advertisers. Finally, we find that Amazon's and skills' operational practices are often not clearly disclosed in their privacy policies.
幾個比較重要的資訊，其中一個是「Network traffic distribution by persona, domain name, purpose, and organization」：
在答案裡面有提到，即使在不考慮 ASIC 的情況下，光是用 GPU 算就可以可以降到 ~5.4 GPU years 了：
Remarkably, we can see that in only 5 years, we're down from an attack costing ~110 GPU years to an attack costing ~8 GPU-years in 2020 (thanks to theoretical improvements & newer GPUs) to just ~5.4 GPU years nowadays (thanks to newer, faster GPUs).
In a more realistic way, it would take less than a day to do it on a super-computer such as the one owned by the US Department of Energy's Oak Ridge National Laboratory (ORNL) named "Summit".
According to the report firefighters on the scene found electrical arcs more than one meter long flashing around the door to the power room, and it took three hours to cut off the power supply because there was no universal cut-off.
另外電力室本身的設計也不利於防火 (木造天花板？)，而且電力管道也沒有隔離：
The power room had a wooden ceiling designed to withstand fire for one hour, and the electrical ducts were not insulated.
另外因為節能的設計，他們設計了多個通道讓外部的空氣容易進入 data center 交換熱量，但這也導致了火苗很不容易熄滅：
Once the fire escaped from the power room, it grew rapidly. The report says that "the two interior courtyards acted as fire chimneys". JDN claims the spread of fire may have been accelerated by the site's free cooling design, which is designed to encourage the flow of outside air through the building to cool the servers.
Lanner’s “IIoT-I530” embedded PC runs Linux on an 11th Gen U-series CPU and supplies with up to 64GB RAM, 2x 2.5GbE, 6x PoE+, 2x COM, 4x USB 3.0, 2x HDMI, 3x M.2, SATA, mSATA, and DIO.
