bit_razor··on Systems Correctness Practices at Amazon Web Services
Fiar point. I was thinking about antithesis, but it's not open source (yet?). Turns out I also didn't read your comment well enough. Back to lurking I go.

bit_razor··on YouTube is banning anti-vaccine activists and blocking all anti-vaccine content
Regardless of why this was downvoted, it deserves an upvote for being correct.

"Are there long-term side effects caused by mRNA COVID-19 vaccines? How do we know?" Basically, no because we've studied them. mRNA vaccines are notoriously easily destroyed.

Is there some common knowledge that counters this that I'm missing?

To add to this madness, even if you design your own chips and software stack, the fab that printed your chips might have modified your design. Perhaps you can design a chip that's resilient to modifications?

Is it possible to build a chip that only executes instructions encrypted by your key? I'm not talking about just decoding to L1 and executing plaintext there, but having a full pipeline that can only work on your encrypted instructions.

bit_razor··on Amazon has no idea how to run an app store
I'm curious if there isn't a misunderstanding here. Are you certain that the actual shipping time is going over what you paid for, or is it just the total time since order is greater than the selected shipping speed?

I suspect that the delay you see is in the time it takes their warehouse not only to package your goods, but to also privately deliver it through their network to the most optimal ship point. You also have to factor in whether the carrier they've chosen supports delivery on the days you expect the item to ship.

Amazon should really make the difference between processing and shipping clearer, and perhaps factor it into the delivery estimates when you purchase. I've also always wanted them to let you chose carriers if you pay for a certain delivery speed instead of picking one themselves. I always have to cross my fingers that I don't get USPS for that important item.

bit_razor··on The cost of dynamic vs. static dispatch in C++ (2013)
My beef with this article is that it misleads you believe that need CRTP is the only way to eliminate vtable lookups on interface calls. It left me wondering how CRTP compared to invoking DynamicImplementation::tick() directly. The article is actually quite great otherwise.

How is this an apples to apples comparison? Instantiating CRTPInterface with Implementation is no different than just calling DynamicImplementation::tick() directly, so why not benchmark that?
