The title was edited only after the original propitiated the story into notoriety. The votes before and after the intervention therefor became in conflict. Hacker News aided in the spread of disinformation.

I asked you not to argue semantics, but you're doing it anyway. I didn't respond here to argue protobufs actually is bad, since all software is suited to something for somebody somewhere. In fact, I can just do that now: Protobufs

Why is that absurd? Products used by billions of people may just as well not have serious requirements. I beg not to debate semantics, indeed my own fault, but in the world of network software requirements can start to get very serious, str

CBOR also delivers optimal wire sizes with its variable length encoding. Ceteris paribus, there's no technical advantage to using protobufs. The choice is almost always non-technical (business, platform, partnership, etc) or simple nai

I'd like to apologize for simply not using the phrase "non-consenting." Including the word "democratic" in my point is probably far too convoluted. The definition of a legitimate regime (going back to Locke's t

I just want to make this political science point absolutely clear without ambiguity: when an illegitimate (non-democratic/non-consenting) regime engages in "anti-corruption" they are doing nothing more than purging disloyalty

There's no single confluence where every application's needs are provided by a single C/C++ implementation's default allocator. I'll just speak to one example off the top of my head: the default glibc malloc() store

The statement is a slippery-slope, but it's not a fallacy. The concept of a monopoly is one we can agree on, and the exposure to the risk being described is a real one. What is to stop a monopoly deciding 30% becomes 40%? Not much.

Indeed the conceptual fork point mentioned is RocksDB 6.2.1 which came before those features. The problem with RocksDB is that one thread only makes one request at a time. I should've phrased my question more succinctly: Is Pebble&#x2F

Concurrency and multithreading are a major focus of both Go and RocksDB. This introduction makes little mention of those areas, and I'm curious if there's any more to be said on this. The article lists several features being reimp

I assume it followed an attempt by Google to influence how these funds are directed at Mozilla. Is Servo a threat to Google? Perhaps reinventing everything in Rust is just a detestable waste of resources?

As a skeptic of Rust I really appreciate this. I was very pleased to find the ASM option in the drop-down menu specifically. Coming from C/C++ I've found it difficult to understand how and why Rust generates the code that it does.

It's cool to see Matrix work inside emacs but I think the spirit of the OP alludes to putting a little emacs in Matrix too. Composing messages in that band-aid at the bottom of Riot is a great example of a stress-inducing UX. Some venu
