When choosing a creature to sacrifice (originated from a "sacrifice a creature" instruction), if the creature that is being sacrificed has "sacrifice this creature (for whatever result)", does it trigger?  Does it make any difference if the target creature is a forced sacrifice instead of a volunteered sacrifice?  Example scenario: I play  to draw 2 cards and target  as the sacrifice. Does this trigger Bile Urchin's "Sacrifice Bile Urchin: Target player loses 1 life."?  I may have thought about this for too long and confused myself, so a little clarification would be great.
Say I have a Zombie token, , and  on the battlefield. Can I sacrifice the Zombie token to activate both the Altar's and Seer's abilities?  Similarly, if I have one card in hand, and  and  on the battlefield can I discard the one card to both of their abilities?  If I have a  with 3 charge counters can I activate both of its abilities by tapping it to add a counter, and tapping it to remove 3 counters and destroy a permanent without untapping it in between?
How can I bump other users' unanswered questions? I'm looking around for answers to my questions on several Stack Exchange sites and the good boy that I am I don't want to ask duplicate questions.  Often I find that there are other people who asked the same questions, sometimes years earlier, but still don't have an answer. I'd figure I could bump these back to top, but if I don't have enough rep for a edit (or comment), how would I do that?  Or, in that case, I should just post a 'newer' version of the same question? Volume of an n-simplex It's rather tedious to show using Fubini's Theorem and induction on $n$ that the volume of the region $x_1+x_2+...+x_n \leq 1$ with $x_1,...,x_n$ nonnegative is $\frac{1}{n!}$.  Is there an easier way to see this? Windows 10: How to change a theme slideshow time interval? It's all int the title; I find myself unable to set a precise time interval defining how often the background pictures of the theme I am currently using change.  The only similar option available in Windows 10 settings applies only to single background images and not to multiple background images included in a theme.  Thanks in advance,  N. In  they've somehow created "wireless" networks, meaning networks that connect two components but don't have an actual wire in the schematics.

What does "if not" mean in the given sentence Logistic regression with binary dependent and independent variables Why is my camera metering indoor scenes as darker than I expect, forcing me to use a high ISO? I am shooting in natural light, with my subject facing a full floor-to-ceiling south facing window. You would think my meter would allow ISO between 200-400 in bright light, but I was lucky to get it to 640, with f/3.2 and 1/60 (manual mode).  I've read other places that people say put your ISO down to 100 for indoor shots for greatest clarity (especially sharp eyes) — but don't know how I can with subjects potentially moving. Is there a setting in my camera (Canon 5D Mark III) I am missing, or something that might be making my meter need more light? Suppose John has 5 sweets. Is there any difference between the following two sentences?     Jack has 3 times as many sweets as John.      Jack has 3 times more sweets than John.   I prefer the first construction and would know unambiguously that Jack has 15 sweets in this case. However in the second construction I would be inclined to think that Jack has 20 sweets, since it seems to suggest 15 sweets in addition to the original 5. Not sure if this option ever existed, but the new QGIS version hides a lot of things somewhere else and this seems so simple that I'm kind of convinced it was possible to do this before. I have quite a large data set with ship tracks. I now want to analyse individual ship tracks (made from point layer with  Plugin). However, it is so crowded that it is hard to look at individual tracks. I don't want to save each single track as a new layer, so I wonder if it is possible to select one track in the Attribute table and display only that one on the map/hide the others? I recently installed Ubuntu Server edition 13.10 (Saucy Salamander). But I have run into a bit of problem. At the end of the installation, it asks about several extra packages whether you want them or not, like OpenSSH server and virtual machine host. Here's what I'm looking at:  Now, my problem is that I can't remember if I have checked the &quot;virtual machine host&quot; checkbox. How do I check if my server has the corresponding packages? What packages come with the virtual machine host?

I have the strange experience that from the combination      \glossarystyle{altlisthypergroup}     \clearpage     Printing acronyms     \printglossary[type=acronym]   only the debug message is printed, the glossaries not.  Even, the \printglossary leads to hanging. At the same time, in the text commands like \gls{} work as expected.  Any advice, what other package can interfere with glossaries? (It is part of a bigger project, the MWE works as expected.)    I changed to command line version from TeXstudio.

And also, why the pdflatex hangs if I try to continue with using pdflatex again? I'm working with some code that widely uses the idiom of returning a pointer to a static local variable.  eg:  char* const GetString() {   static char sTest[5];   strcpy(sTest, "Test");   return sTest; }   Am I right in thinking that this is safe?  PS, I know that this would be a better way of doing the same thing:  char* const GetString() {   return "Test"; }   Edit: Apologies, the function signature should of course be:  const char* GetString(); How to overload __init__ method based on argument type?
