> “Oh this person just throws stuff on Medium? Probably not worth my time.”
This is just the worst attitude. Someone's not worth your time because they don't have the knowledge or time to stand up a website on their own domain? People who aren't web developers might still have something interesting to say.
For me, it's not that they can't stand up a website, but that there's very little barrier to entry. An article on the New Yorker, say, tends to be better than one on Medium not because the writer can make a website but because they have a strong editorial team that only publish content of a certain quality and edit it to improve it. An article on Medium may not even have been proofread.
I don't think that's a fair comparison. The New Yorker is a magazine that curates and publishes articles by people who write for a living and stakes its reputation on only publishing pieces of a high quality.
The distinction here really is if someone publishes on joesblog.com or on medium.com/joesblog. Both are self-published rather than selected for publication, but the OP was of the opinion that joesblog.com is an indicator of higher quality of content, which I don't think is true. All it indicates is that someone has been able to set up a website.
Martin Gardner came up with a somewhat contrived but still brilliant extension to this:
"Wouldn't the sentence 'I want to put a hyphen between the words Fish and And and And and Chips in my Fish-And-Chips sign' have been clearer if quotation marks had been placed before Fish, and between Fish and and, and and and And, and And and and, and and and And, and And and and, and and and Chips, as well as after Chips?"
Containers or environment management solve this problem quite easily. All of my major projects have a conda environment alongside them, and I expect I'll be shifting things over to Docker containers as my org starts shifting things to the cloud.
Finding cycles in a graph is not that simple though. I'd expect they just keep a few state bits in each cell and when a cell that's marked as being in the process of calculation gets hit again as a dependency you've hit a cycle.
This is just the worst attitude. Someone's not worth your time because they don't have the knowledge or time to stand up a website on their own domain? People who aren't web developers might still have something interesting to say.
