I don’t think it is so binary.

If there is more friction to communicate with me I expect to hear from people less often.

As an example, my friends that only use Discord and not SMS or Signal definitely hear from me less frequently. It doesn’t mean we’re not friends, but we do communicate less frequently.

That’s a bit uncharitable. It made perfect sense to me. I also learned something about Japanese lacquer.

In the exact same configuration? Yes.

The date of the notice is October 28th. The separation dates given in the letter are 90 days out from the date of the notice (for some technical reasons, some employees had a separation dates a bit further out.)

The books are also physically really pleasant to hold and look at.

I’ve read each book they’ve published and enjoyed them all.

I think they’re saying anyone could order “secure” checks with your account number on them.

Excited to say I worked on this feature! (Standard disclaimer: thoughts and opinions are my own and may or may not be shared by my employer.)

To give an idea of the kinds of things you can do now:

  - Keys or other secrets can only be decrypted (via KMS) by an EC2 instance if it is running an approved AMI. 
  - You could build a certificate authority (CA) which only issues a certificate to an instance running an approved AMI. 
This is similar to the functionality that was available in Nitro Enclaves. However, enclaves came with restrictions (such as only being able to communicate through a vsock) that made them not a great fit for all use cases.

I’m more familiar with the 737 (as a hobby, not as a pilot), but for that aircraft the “loss of thrust on both engines” checklist has the start levers as the second item on the list.

Note that in the checklist I am looking at the goal is to restart the engines rather than diagnose the failure and that involves these levers. I suspect you’d notice pretty quickly if they were not in the expected location.
