Right now there isn't a great way to monitor the questions that I am interested in following. What I seem to do now is go to my recent history for questions I have commented on, and then link to the questions from there. The problem is, if I am really interested in a question, I have to monitor it closely. Sometimes I will "favorite" a question so it is easier to access more quickly, because I do not have a lot of favorites. But favoriting is not the right thing to do. I think you should only favorite a question if you really really like it, not to make it easier to follow.  I propose that you can mark questions as "interested" or something like that. What this means, is that you will get notifications for everything associated with a question: any time a new answer is posted, the answer/question is edited, and any comments to any of the answers (or question). This would make it much easier to follow questions. Especially if someone adds a new answer or comment way down the road, after you have long forgotten about the question.  It would also be nice if such a feature allowed you to write a sentence or two to associate with the question to remind you about something. In fact, if this is done, we could just use this feature to implement  to allow an edit to notify downvoters. Instead of that specific feature, you can mark a question as interested after downvoting and add a comment, "remove downvote when fixed".  What do you all think? Do you propose a better way to manage monitoring questions of interest? (The other thing I do is keep a bunch of browser tabs open with questions I am following... and this is messy :-( ).
There has been some discussion about getting notified on comments to questions or answers that don't belong to you, and the long-standing wish to be able to keep track of new answers or developments in questions asked by other people.  Previous discussion in regards to subscribing to questions:                  (very similar to this one)      In regards to subscribing to comments:                    The general feeling - at least here on meta - seems to be against broadening the notification rules, out of fears of useless notifications to flood users' inboxes, turning SO into more of a discussion forum than it should be, etc.   Here's a suggestion that would keep the user 100% in control what they get notified about, not generate any notifications by default, and require only minimal modifications to the User Interface.  Each question and each comment area would get an envelope symbol.    it is inactive (=white) by default.  When those envelopes are hovered over, the tooltip says click to subscribe or something.  When clicked on, the envelope lights up in green or some other colour (but different from the actual notification envelope's orange to avoid confusion.) You are then subscribed to any updates to that question or comment thread.    For each subscription, you receive notifications in the "responses" tab, as if you were the owner of the comment or question.     To unsubscribe from a question or comment thread, you open the page, and click the green envelope. It turns back white, and the notifications disappear from your responses tab (if technically possible - otherwise, there just won't be any new ones added.)    No further functionality, like managing subscriptions or anything, is necessary IMO. If the flood of notifications from a subscribed question starts to annoy you, you just open it and unclick the envelope. Done.   It would make it possible to leave a comment to a newbie's question and make sure their answer reaches you even if they don't know they need to address you using @username You could subscribe to those "oh, I'd like to know the answer to that" questions and receive active notification, instead of them getting forgotten in your favourites list You could subscribe to discussions you are interested in the outcome of, but don't want to participate in. It would (in my opinion) sort out a number of woes aired by many users in a good way, without adding annoyances to those who like the system just fine the way it is. It would not require a change in the visible layout. As far as I can see, the space the envelope would need to be is empty everywhere.   I don't know SO under the hood of course, but technically, the system would be doing what it's doing already, notify question owners of updates - just that the circle of internal "owners" would grow.
Performance differences between visibility:hidden and display:none JavaScript editor within Eclipse I'm looking for an easy and robust way to strip all the comments from a listing. My approach (passing \@gobble to the commentstyle key) correctly removes all the one-line comments and block comments. However, the white space left behind by by block comments remains, creating useless gaps in my listing. See the screenshot below (the red rectangle is my emphasis).

All the little tongues go clack, clack, clack.   What does this mean, and why was the word "quick" used instead of "quickly"? I've stumbled upon a strange behaviour with Windows machines, which seems to be fairly consistent between all Windows versions from Vista/2008 to 8.1/2012 R2; it doesn't happen instead when using Windows XP or Windows Server 2003.  The problem is this: when the network adapter is configured for DHCP and the DHCP server doesn't register DNS records on behalf of its clients (because it can't, or because it's not configured to do so), then the forward A record gets registered, but the reverse PTR record doesn't.  Some more details:   Both the forward and the reverse DNS zones are AD-integrated and accept dynamic updates. All computers are joined to the domain. All computers use the correct internal DNS servers, both when configured statically and when getting their configuration from DHCP. "Register this connection's addresses in DNS" is enabled in the network adapters. Everything is fine when a computer has a static IP address; both the forward and the reverse records get automatically registered. When the same computer is configured for DHCP, the forward record is registered, but the reverse record isn't. This happens for all computers with an OS version >= 6.0, and it's definitely not related to a single machine. No amount of ipconfig /registerdns will change anything. No errors are logged anywhere.   Why does this happen, and how can it be fixed?  And no, configuring the DHCP server to perform DNS registration is not an option here.

What is the word that is used to describe the oversimplification or non-academic discussion of a complex issue?   Typically, I'm looking for a word like pedantic, or puerile, except that the word covers the fact that the discussion is particularly non-academic. I know that such a word exists since I have used it before, but it has skipped my mind. I am trying to prove that any conjugate of $a$ has the same order as $a$.  Let $G$ be a group and let $a \in G$.  An element $b \in G$ is called a conjugate of $a$ if $b=xax^{-1}$.  My professor gave us a hint.  Prove $a^k=e$ iff $b^k=e$ for all $k \in \mathbb{Z}$ implies $o(a) = o(b)$.  My first move is to $b^k = (xax^{-1})^k = (x^{-1})^ka^kx^k = (x^{-1})^kex^k = (x^{-1})^kx^k=x^{-k+k}=x^0$  I am not sure that I am doing this correctly?  I am trying to get $b^k=e$.  However when I raise $(xax^{-1})^k$, I am not sure if I what I have done is correct?  I am kind of confused here. I want to prove that: $\ln(x+1)&lt; x$.  My idea is to define:  $f(x) = \ln(x+1) - x$, so:  $f'(x) = \dfrac1{1+x} - 1  = \dfrac{-x}{1+x} &lt; 0, \text{ for }x &gt;0$.  Which leads to $f(x)&lt;f(0)$, so $\ln (x+1)-x&lt;0$.  Is that a valid proof? Any other ideas?  Thanks. Are humans the only animal that requires "clean water"? Group of order 15 is abelian How do I prove group of order 15 is abelian?
