I was able to see the video without age verification, go figure.

"Why shouldn't it" does not answer the question, which is "what made desktop computers (and servers, to a certain degree) a unique popular product that customers routinely build ou…

I frankly don't understand why RAM for consumers is a thing. I don't know of any other popular consumer good that is routinely built by the consumer out of individual components. Y…

It must be said that "cities", as used in this piece, is a rather generous term. Sedro-Woolley has 13K residents. Stanwood has 9K. They probably don't have enough people on payroll…

I just realized that you might not know what a "bootcamper" is. Facebook's hiring process generally goes like this: - you're interviewed with a random team and evaluated if you'd b…

First of all, AR/VR is a tough problem space, often for reasons not immediately obvious to common folk. Second, Facebook in my opinion is a wrong home for long-term efforts that ma…

I believe the suboptimality concern was more about time to market and innovation velocity, and less about money. At the time FB felt a real sense of urgency given the anticipated A…

Just a small bunch of XROS people came from FB proper (mostly managers) because an average FB SWE has no required skills. Most folks were hired from the industry at E5/E6 and I thi…

XROS had a completely new and rapidly evolving system call surface. No vendor would've been able to even start working on a driver for their device, let alone hand off a stable, co…

Carmack absolutely 100% percent did not say "these people are incompetent". What he said boils down to "these people are world's best experts on writing operating systems and they'…

There were quite a few of high-caliber individuals with equally impressive resumes in the organization to match Carmack's wisdom and ego.

There were almost no kids on the XROS team. The bulk of the team were E6s with graying hairs, multiple kids, and very impressive history of work on other well-known operating syste…
