P (partition tolerance) refers to network partitions. There's nothing a distributed system can do to prevent network partitions; they're a property of the network. The question is, in the face of partitions, what does the softwa

Lyft penalizes you $5 for cancelled rides after some amount of time, at least in SF. Also when the app makes a request on its own and you're not there.

Yeah, I think authentication and authorization are two of the hardest challenges in moving to a fully static app architecture. There're some more details in a talk I gave a few months ago (video: https://youtu.be/vHXcDK

Scala has macros [0], and as you reasoned the type checker has to run after the macro expansion. That's not a huge downside; to the user it still appears to be a single pipeline (parsing -> macro expansion -> type checking ->

Yeah, absolutely. You'd want to run your full test suite (which probably includes heavier integration tests as well) before deploying, but I think in a lot of cases it's valuable to provide, say, 95% accurate feedback quickly.

It's a bit buried in the announcement, but this is also using a new version of protobuf [0] (3.0) which fixes a number of long-standing complaints about the format: * No more required fields * Now supports maps (a huge pain p

Yes, modern violins differ in various ways from baroque ones, and most of the surviving instruments from that era were "updated." The key differences include the length of the neck, which was shorter as players didn't use as

As a violinist, this is exactly right. Violins are not standardized, and are certainly not interchangeable. Everything from the dimensions of the body and fingerboard to the exact locations of the "sweet spots" where the instrumen

There are definitely companies missing (I have personal knowledge of a few). In particular, it will underreport for profitable B2B companies that haven't raised in a while or at anywhere near their present valuation.

Good luck getting everybody to upgrade their kernel to support your new transport protocol. Realistically, UDP and TCP are what we have. We may wish they were more suited to modern use cases, but realistically we must build on those found

This is true, but also a false dilemma. Rust provides an escape hatch in the form of the `unsafe` keyword. This allows the implementation of efficient data structures, while still providing static safety guarantees to the vast majority of c

Of course. I should clarify that I fully support self-driving cars. I've done research in the area, and I'm a big believer in their promise. In fact, that's why I'm so aghast at these guys. They're (at best) deliver

No, this is how people die. The agile startup mentality is great until you try to apply it to domains that are literally life-and-death.

Optional gc is not something I've seen work in practice. Apple abandoned their attempt because of the difficulty getting gc'd and non-gc'd code to play together nicely. Rust has (and may again) offer something like optional G

What I think you're missing is that in JS, this is not being run concurrently. Existing JS runtimes are single-threaded—if you actually want to take advantage of multiple CPUs you must run more than one process. It's very easy not

Right. It's SOP for tech companies to list basically all of engineering as R&D for tax purposes.
