Completely aside from the content of the article, this is the second subscriber-only LWN.net article I've seen posted in the past week or so, and I'm sure there have been others. Please be careful with the articles you choose to post.
While this may indicate that LWN needs to improve (or create) its paywall, if articles like this lead to new subscriptions they may be able to just chalk it up to "advertising" without breaking limited sharing of articles.
As an optimistic anecdote, this being the second such article in a week that I've really enjoyed just pushed me over the edge and I'm now an LWN subscriber. Hopefully I'm not the only one.
I really wasn't familiar with LWN prior to seeing links to subscriber-only articles semi-frequently on HN, and honestly these days I'm embarrassed I didn't know about it sooner as I'm a Linux sysadmin and LWN's weekly edition is just about exactly the news I want to keep up with my job.
Welcome to the lwn.net subscriber gang! I'm an ordinary desktop linux user and have been a subscriber for many years. It has been, and still is, my go-to site for in-depth news on linux, whether on kernel matters or on the linux ecosystem.
I'm the one who posted this article and so far, I have not had any warning mail from lwn.net about posting subscriber only content. But I do take care to try to only post content that I believe is of interest to HN.
