摘一个scoop安装的docker遇到的启动问题

The pipe access that the error message mentions is a (probably unrelated) issue when docker client is run by non-admin users (see here). I think the most likely explanation is that the docker service has failed to start. When you ran dockerd you were actually starting an instance of the daemon - and the line API listen on //./pipe/docker_engine means that the system service hadn’t started previously - as the instance you started could create the pipe. ...

Welcome to share your thoughts and experiences. About Myself Verbally, my logic struggles to keep up with my thoughts. I prefer practical work over idle speculation and value genuine experiences over empty actions. I enjoy tinkering with new computer-related technologies, both hardware and software. Over the past three years, I’ve built an integrated system—from sensors to microcontrollers to servers—as part of my thesis. I dislike competing for superficial recognition but still want to prove myself. I’ve participated in two mathematical modeling competitions, never achieving the top rank, but the results weren’t bad either. ...

A letter to be Opened in the Event of My Death | To Clare

December 10, 2006 Dearest Clare, As I write this, I am sitting at my desk in the back bedroom looking out at your studio across the backyard full of blue evening snow, everything is slick and crusty with ice, and it is very still. It’s one of those winter evenings when the coldness of every single thing seems to slow down time, like the narrow center of an hourglass which time itself flows through, but slowly, slowly. I have the feeling, very familiar to me when I am out of time but almost never otherwise, of being buoyed up by time, floating effortlessly on its surface like a fat lady swimmer. I had a sudden urge, tonight, here in the house by myself (you are at Alicia’s recital at St. Lucy’s) to write you a letter. I suddenly wanted to leave something, for after. ...
