The idea stems from one of my players but can you tie magic rings (enchanted with magic missile) together and activate them all in one action? So for example they have ten magic rings all with the same spell, can he use all the rings as they are tied together (essentially creating a single object.)
Say a creature owns multiple items with wording similar to this:  As an Action, you may speak the command word to [...]  Say the creature has deliberately obtained such items, perhaps by creating them itself, to have the same command word. Can this creature use one action to speak the shared command word and activate multiple items at once? The purpose of this question is not to cheese my DM. I am writing a short story and like to keep my D&amp;D fiction as close to rules-accurate as possible.
How common is "thrice"? I would like to transform 5V 500mA (from USB power) into 12V with a few cheap components.  Is this possible with the help of some generic parts (and not with the help of some expensive transformer, etc.)?  Also, how many milliamps would this provide? How do I check if a list is empty? Prove that $\lim_{n\to\infty}a_n\le \lim_{n\to\infty}b_n$ How is the zero flag set in terms of hardware? What happens when identical overlapping effects have their end-condition met? Do Wine Viruses only work while Wine is running? I'm trying to fill empty space in my mesh, and I looked at the knife tool page on the Blender Wiki, and I'm not sure if there's a way to make it so that a new edge is made using the knife tool. I took a screenshot, and hopefully it'll explain better than I can of what I'm trying to do. Oh and I'm using Blender version 2.71, by the way. I have End Date column and I want to add 14 Days on it auto when created, can I do it by workflow? Can I do it via jQuery. If yes how? if no how I can do it? How to set one header for each page using multicols I try to download a file with wget and curl and it is rejected with a 403 error (forbidden).  I can view the file using the web browser on the same machine.  I try again with my browser's user agent, obtained by . I do this:  wget -U 'Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' http://...   and  curl -A 'Mozilla/5.0 (X11; Linux x86_64; rv:30.0) Gecko/20100101 Firefox/30.0' http://...   but it is still forbidden. What other reasons might there be for the 403, and what ways can I alter the wget and curl commands to overcome them?  (this is not about being able to get the file - I know I can just save it from my browser; it's about understanding why the command-line tools work differently)  update  Thanks to all the excellent answers given to this question. The specific problem I had encountered was that the server was checking the referrer. By adding this to the command-line I could get the file using curl and wget.  The server that checked the referrer bounced through a 302 to another location that performed no checks at all, so a curl or wget of that site worked cleanly.  If anyone is interested, this came about because I was reading  page to learn about embedded CSS and was trying to look at the site's css for an example. The actual URL I was getting trouble with was  and the curl I ended up with is  curl -L -H 'Referer: http://css-tricks.com/forums/topic/font-face-in-base64-is-cross-browser-compatible/' http://cloud.typography.com/610186/691184/css/fonts.css   and the wget is   wget --referer='http://css-tricks.com/forums/topic/font-face-in-base64-is-cross-browser-compatible/' http://cloud.typography.com/610186/691184/css/fonts.css   Very interesting. Navier-Stokes system How to convert strings into integers in Python? I have a tuple of tuples from a MySQL query like this:  T1 = (('13', '17', '18', '21', '32'),       ('07', '11', '13', '14', '28'),       ('01', '05', '06', '08', '15', '16'))   I'd like to convert all the string elements into integers and put them back into a list of lists:  T2 = [[13, 17, 18, 21, 32], [7, 11, 13, 14, 28], [1, 5, 6, 8, 15, 16]]   I tried to achieve it with eval but didn't get any decent result yet. Showing that $e^z=z$ has infinitely many solutions One of our review problems for my complex analysis final is the following:     Show that $e^z=z$ has infinitely many solutions in $\mathbb{C}$.   I've seen a few solutions online, but none of them have used material that was covered in our introductory complex analysis course. Would anyone be able to provide a simple solution?  I'm trying to think of ways to invoke bounding in some way but I can't seem to come up with anything. RESTful Authentication What does RESTful Authentication mean and how does it work?  I can't find a good overview on Google.  My only understanding is that you pass the session key (remeberal) in the URL, but this could be horribly wrong. Grant group traversal rights on a folder Idea behind proof that $\frac{21n+4}{14n+3}$ is irreducible for all $n$ Archive by Year Bind a key for multiple units to use the same spell The "proper" way to test if a service is running in a script My problem:  I'm writing a bash script and in it I'd like to check if a given service is running.  I know how to do this manually, with $ service [service_name] status.  But (especially since the move to systemd) that prints a whole bunch of text that's a little messy to parse. I assumed there's a command made for scripts with simple output or a return value I can check.  But Googling around only yields a ton of "Oh, just ps aux | grep -v grep | grep [service_name]" results. That can't be the best practice, is it? What if another instance of that command is running, but not one started by the SysV init script?  Or should I just shut up and get my hands dirty with a little pgrep?
