Technical guides usually are written against a particular version of OS/Toolchain.
When a reader want to do the same in a different version (newer or older), there can be different behavior.
As the comment period of the published article is not that long, so people (that is me) naturally post a link to the article at Ask to discuss.
It will be great if the article author can get a notification whenever their article is linked/mentioned in Ask. As response from the author will be very valuable to the reader.
ps. It might be impolite to directly mention the author in the new Ask topic, or it is hard to find out the correct username to mention.
