      As we did last year, I've set up a temporary sub-group that we can use for this year's Advent of Code at ~comp.advent_of_code

      Some discussion and solutions were starting in this thread, but it will be easier to organize inside a devoted sub-group, and also makes it simpler for people to both find and avoid the relevant topics.

      If you posted solutions in that topic, please move them into the threads for Day 1 and Day 2.

      I automatically subscribed everyone that commented in or voted on that original topic, as well as everyone that posted a comment in any of last year's topics, but nobody else. So if you're interested in participating in Advent of Code or discussing it, please subscribe to the sub-group. Posts from the sub-group won't be shown to logged-out users by default either, so any logged-out users that want to observe will need to visit the sub-group directly (or you're welcome to email me and request an invite so you can register and subscribe).

      I've also set up scheduled posts to happen automatically as each day's puzzle unlocks.

      Currently, controlling one of my PCs from another requires me to manually log into Windows on the remote computer so I can get the TeamViewer pw and then connect from the host. Is there another program that will launch at Windows startup so I log into Windows on the remote computer from the host? I don't need internet remote control and I'd prefer a free alternative that doesn't require an account or internet access to enable this type of feature (which I believe TeamViewer does). Remote computer is on Win 8, host on Win 10. EDIT: I was wrong, see below.

      I've just read a journal from someone on another site saying that they wished there was a blacklisting system which stopped them seeing submissions from, to or about certain other users in their feed, as it is potentially trauma-inducing for them to log in and keep seeing them come up. I assume that the person looking for this blacklist isn't realistically able to just leave the site, because it's the most populous of its kind and serves as an art portfolio or source of income.

      Is this, or something like it, actually possible to do with custom ad-blocker rules, or do they need to just wait for the site's admins to get around to it?
