In my experiment, every thread communicated with two other threads through lock-free queues, and each thread’s work depended on receiving that work form another thread. In other words, the threads were very dependent on each other, and they

Agreed, strongly. I was just concerned the original comment may not have been fully understood.

I was massively surprised a few years ago how efficient Linux thread context switching could be. I designed and implemented a dynamic scheduler for a streaming dataflow language a few years ago [1]. We wanted a runtime system which could ha

I proposed a scenario where it seems to me that SMS-2FA does achieve something. What is wrong with my understanding with how it helps with that scenario? To be clear, I'm not talking about credential stuffing. I'm talking about my

But I'm already immune to credential stuffing because I have long, unique passwords, no? And credential stuffing would be taking my username and password from Foo and using it with Bar, right? But I'm talking about the username an

I believe the arguments that SMS-2FA is not effective against phishing. (Or, at the least, I can't provide a compelling counter-argument.) But I had always thought of SMS-2FA against a more banal problem: 1. You have a unique, long pas

The disconnect is that we disagree on how to establish causation. I follow what I believe to be the generally accepted standard that when dealing with only two people, it’s not valid to assume that medical intervention x , later followed b

Structural racism often means there is no one person to blame - there's not going to be a person we can hold up and say, "Here's the racist!" This was a racist outcome because the students, staff and parents in the min

I still find it useful to write those emails, even if I'm asking to talk to someone. The email serves as an agenda, it forces me to reason through the issue, and it serves as a long-term record of the issue. But the request for the mee

The reason I pick the NBA is because there are only 450 positions available (30 teams, 15 players per team). This is the least number of total positions in popular team sports in the US. The ratios will never be perfect, they just need to b

That is a good framing. When I explain it to people, I compare it to the NBA. Except it's like trying to get into the NBA when all of your coaches over your entire basketball life up until that point have been in the NBA. Proximity c
