I have a question about a particular sense of the adverbs "still" and "yet":       to a greater extent or degree     Most dictionaries has the entry above for both "still" and "yet".  So, the following are standard English:          It was a still more difficult problem.      It was a yet more difficult problem.         But dictionaries seem to allow a alternative placement for "still", so the following is possible for using "still":           The problem was more difficult still.         No such alternative placement for "yet" is suggested in dictionaries, to allow the following:            The problem was more difficult yet.        Is sentence 4 standard English overlooked by dictionaries?
what is the difference between "yet" and "still"?   When we can use "still"? and when we can use "yet"?   Are they synonyms or not?  "The plan could yet succeed." Can I use "still" in that sentence instead of "yet"?  "I still don't understand." Can I use "yet" in that sentence too?
I was thinking about this issue from time to time but I didn't know whether it really exists or just an speculation on my side until today when I woke up [!], I saw  downvoted (in the meantime I'll leave that answer unedited for the sake of discussion; note that this is just a sample. I'm not asking "how to deal with this specific answer." The question is completely general as it's nearly impossible to keep track of all of your answers to see whether they require updating or not). While the downvoter didn't explain a thing, I suspect the reason is that the answer is no longer applicable (It's one of the new features in iPhone OS 3.0). As we go to celebrate a long sequence of birthdays for Stack Overflow (hopefully!), we're going to see lots of answers become obsolete. How we're going to deal with this issue? Nicely discouraging serial upvoting Probably everybody who is very active on SO has experienced cases of random, serial upvoting as the expression of thanks from a (usually newbie) user. The pattern is usually 5 or more upvotes on your latest answers. The upvotes will be detected within 24 hours, and removed. (Or so I assume.)  No harm done except maybe a minor irritation for people after one of the &quot;rep cap&quot; badges because they are shown a higher reputation than they actually have. Still, I was thinking whether, in an attempt to channel the positive attitude into more productive areas, it would be worth showing a tooltip on the third upvote for the same person within time frame x:  Please use one upvote, a comment, or some quality content of your own, to say thank you Large numbers of upvotes for the same user may become invalid as part of our spam detection mechanisms.  Does this make sense? Maybe it is too localized and rare, but it has happened to me three or four times in the last two weeks alone. You decide.  Clarification: I am not advocating putting up any kind of barrier on upvotes. . I'm suggesting informing people of the barrier and the futility of their ten or so upvotes for a single person because those votes are likely to be revoked.  Update: @devinb makes the good point that &quot;saying thanks&quot; is not the only possible reason for serial upvoting, and the message wouldn't make sense then. The point still stands: Your votes aren't going to count, and when it comes to up voting (which is always some sort of positive behaviour, however misguided if done indiscriminately) I think it's fair to inform people of this. I am trying to pass a reference to a two-dimensional array to a function in C++. I know the size of both dimensions at compile time. Here is what I have right now:  const int board_width = 80; const int board_height = 80; void do_something(int[board_width][board_height]&amp; array);  //function prototype   But this doesn't work. I get this error from g++:  error: expected ‘,’ or ‘...’ before ‘*’ token   What does this error mean, and how can I fix it? Shapefile layer no longer editable (toggle edit option greyed out) in QGIS When I try to install any software, I encounter this error, and therefore I cannot update.

I have the following counters defined (hopefully this is the right way to do it!)  \newtheorem{thm}{Theorem}[section] \newtheorem{lemma}[thm]{Lemma} \newtheorem{cor}[thm]{Corollary}   This works as I would like (i.e. Theorem 1.1, Corollary 1.2, Lemma 1.3, etc.)  My problem is \cref always returns Theorem 1.2, Theorem 1.3.

(In my preamble)  \crefname{thm}{theorem}{theorem's} \crefname{lemma}{lemma}{lemma's} Brown sugar instead of white sugar When I define amsthm theorem environments with shared counters, autoref messes up the names of the references.

I did the last digit case pretty handily, and now I'm stuck at last two. Recommendations for good Newtonian mechanics and kinematics books What are some good books for learning the concepts of Kinematics, Newton laws, 2D Motion of Object etc.? What is the motivation for including the compactness and semi-simplicity assumptions on the groups that one gauges to obtain Yang-Mills theories?  I'd think that these hypotheses lead to physically "nice" theories in some way, but I've never, even from a computational perspective. really given these assumptions much thought. Quieting down a Dell PowerEdge r710 I run a Dell PowerEdge r710 server out of my house and I'm moving in with roommates in a couple weeks. Unfortunately I don't think they'll appreciate the ~70dBA it generates and I'm looking for ways to make it quieter.  I looked into replacing the fans with something less noisy, but unfortunately none of the quieter options move nearly enough air. The best one I found has been the , but at less than half the CFM (30.3 vs 67.85 on the stock  fans) it doesn't seem powerful enough.  I've also thought about putting  around the server to quiet it down, but acoustic panels also have the downside of acting like insulation, so heat could turn into an issue. Display bare HTML from hook_menu() What would be the cleanest way to route URLs to functions and return only the HTML output from those functions (a.k.a. the menu callback)?  If I use hook_menu() the string that's returned will be the HTML within the rest of the site. I want the page to display only the string returned from the menu callback.  Should I use drupal_set_header() in the same way drupal_json() does? Is this not inefficient having fully bootstrapped Drupal, and then changing the header at the last minute?  I want the fastest code path possible since this is going to be for widgets on external sites.  I could start with a standalone .php file and bootstrap what I need but the hook_menu routing is nice.    How should you do this? What makes Stealing Signs wrong? How can I copy/transfer games via external hard drive? I have successfully transferred "Killing Floor" from my brother's laptop to my own via external hard drive. The problem, now that I have all the files, is that I don't know how to launch the game through Steam. All I did was copy files from his Laptop to the hard drive, then from the hard drive to my laptop, then I put the files in the "Steamapps" folder under "Steam" in my laptops hard drive. So the question is, how do I start up the game through Steam? I have a select control, and in a javascript variable I have a text string.  Using jQuery I want to set the selected element of the select control to be the item with the text description I have (as opposed to the value, which I don't have).  I know setting it by value is pretty trivial. e.g.  $("#my-select").val(myVal);   But I'm a bit stumped on doing it via the text description. I guess there must be a way of getting the value out from the text description, but my brain is too Friday afternoon-ed to be able to work it out. A Particular Two-Variable System in a Group Suppose $a$ and $b$ are elements of a group $G$. If $a^{-1}b^{2}a=b^{3}$ and $b^{-1}a^{2}b=a^{3}$, prove $a=e=b$.   I've been trying to prove but still inconclusive. Please prove to me.  Thanks very much for proof. How do I watch a file for changes? What makes a good tag separator? I'm building an application to allow technical people to enter configuration changes.  I'd like to add tags to each change.  Right now I'm using spaces, commas and semicolons.  It appears SO uses spaces and requires hyphens to make multiple words.  I read something that leads me to believe that WordPress uses commas and that a space isn't a separator.  Is there any best practice out there?  Has anyone had any good or bad experiences?
