> Trusted Execution Environments (TEEs) like Intel SGX and AMD SEV-SNP and in general hardware attestation are just f*d. All their keys and roots are not PQ and I heard of no progress in rolling out PQ ones, which at hardware speeds means we are forced to accept they might not make it, and can’t be relied upon.

compare to SGX, a more critical impacted component is TPM chip, secured/measured boot depends on TPM, and cost of replacing all servers and OS ...

one thing I liked about cobra is the auto complete support, but I don't like the manual process of define command and parameter and not easy to extend, so I wrote https://github.com/hujun-open/myflags, it is built-on top of cobra but allow uses a struct to define all commands/args and also easily to extend support new types (even existing types)

because Trump said TSMC is stealing US chip biz, and threaten 100% tariff [1]. I think this is TSMC's attempt to avoid tariff

one tip of the list I can't agree more is the www.seat61.com for train ticket, especially if you travel in Europe, where train is the most convenient way to travel between cities/nations but man is it such complex system, there are so many different rail companies and lines, this website gives a clear instruction on options, price and where to buy the ticket

quote from tiktok's webiste https://usds.tiktok.com/usds-myths-vs-facts/: ``` Myth: TikTok’s parent company, ByteDance Ltd., is Chinese owned.

Fact: TikTok’s parent company ByteDance Ltd. was founded by Chinese entrepreneurs, but today, roughly sixty percent of the company is beneficially owned by global institutional investors such as Carlyle Group, General Atlantic, and Susquehanna International Group. An additional twenty percent of the company is owned by ByteDance employees around the world, including nearly seven thousand Americans. The remaining twenty percent is owned by the company’s founder, who is a private individual and is not part of any state or government entity. ```

depends on how much "k8s native" code you have, there are application designed to run on k8s which uses a lot of k8s api and also if you app already micro-serviced, it is also not straight forward to change it back
