(I work for Docker). We will be updating the UI to show status of each image (active or inactive). We will be updating the FAQ shortly to clarify this.
Hello, I am one of the engineers on Docker Hub. If the image was ever pushed via a tag which must be the case if it was done via docker CLI then that image is never deleted (unless the tag is deleted from Hub UI and no other tag refer to it). This means if sha256:c34ce3c1fcc0c7431e1392cc3abd0dfe2192ffea1898d5250f199d3ac8d8720f was referred by latest tag which was pushed to another image sometime later then `FROM tomcat@sha256:c34ce3c1fcc0c7431e1392cc3abd0dfe2192ffea1898d5250f199d3ac8d8720f` will continue to work. Apologies for not having this documented. I'll work on getting this documented on https://docs.docker.com/docker-hub/.
I whole heartedly agree with your free market solution. However, one of the concerns is that immigrants are often ready to work on lower pay just to get in the country. So, wouldn't they bring down the overall wages of these jobs and affect citizens? Are you suggesting that they would switch jobs for better pay once they move to the US in effect balancing the job market?
Yes. If you bring someone in for $50K but their market price is $90K and it's easy to switch, why would that person not switch jobs ASAP?
When that happens, the company takes a hit and is less likely next time to bring in more people because of the associated costs of HR, interviews , visa fees, immigration lawyers, onboarding, time wasted on getting them up to speed on the project etc.
It would be a huge blow to body shops.
This results in fewer people coming in unless they are really needed.
Right now H1B employees are stuck in jobs without normal pay hikes for years and can be forced to work longer hours. That's how the companies make their costs back and much more.
Just out of curiosity: how would you feel if I answered this question by using existing function [1] in stdlib? Would you consider that as (good) sign of knowing the tools or would you prefer a fresh implementation?
I see it as a positive if a candidate uses an existing solution to the problem. That's exactly what a good engineer would do in the real world.
But then I take away the library/method and re-state the problem. Because the point is to see if they can understand the problem, and devise a solution.
