is a 1/1 creature, costs 2 mana and allows the player to draw a card when it is played. Under what circumstances (if any) would it be worth playing the coin on the first turn to summon this card, sacrificing future mana advantage for immediate card advantage?
There are various articles on Hearthstone opening strategy which suggest it's a bad idea to use early-game spells and summons to damage your opponent directly, and that you should instead save them for minion removal.  An example: your starting hand contains an Elven Archer, a 1-cost 1/1 minion that does a point of damage when summoned. I've seen it advised that if going first, with that card in your hand, you should not play it, but save it for minion removal.  Another example:  Going second against a Rogue with a 2-cost 2/1 Loot Hoarder, Deathrattle: draw a card in your hand. The advice was not to play it and save the coin, because on her second turn, the Rogue can generate a dagger and kill the Hoarder.   I understand why, in most circumstances, it's better to remove a minion than damage the enemy. What's bugging me about these particular opening examples is why they're a better idea than doing nothing and ending the turn.  In both cases, you've wasted a point of mana, and the chance to take the initiatve. By having a minion on the board first, you can use the following turn to attack with that minion, possibly removing an enemy summon and leaving you clear to summon onto an empty board.   The Loot Hoarder one I find particularly puzzling. If the Rogue gets a dagger and kills it, you still have the initative, you've forced the Rogue to make what's possibly a suboptimal turn-2 play, you've done 2 damage to the Rogue and you got a card into the bargain. Sounds like a pretty good use of the coin to me.  What am I missing here?
Is there a word for colloquial forms of address? For example, "dude," "man," "buddy," "pal," etc, when used to stand in for someone's name.  "Hey, pal, how's it going?"  Is there a word for terms like these?  Or is "colloquialism" as close as we can get? Did regular Americans speak the way actors in the 30s and 1940s did? I watch a lot of old movies, and I've noticed that American actors of the 1930s and 1940s often spoke in a quasi-generic-posh-British accent.  Katherine Hepburn's accent would be the perfect example. It seems exaggerated, and I imagine it was not common off the stage and screen. What was that? Was it just an accent or was it a dialect? Did real people actually speak that way? How do I install the Nvidia drivers? I just ordered the Nvidia GTX card. I have a dilemma, though. Should I keep using the driver which is available in "additional drivers" in Ubuntu, or should I install the driver from the Nvidia site?  So which driver is the best for me? Java: Avoid inserting duplicate in arraylist Idea behind proof that $\frac{21n+4}{14n+3}$ is irreducible for all $n$ So, I was given the following problem as part of a homework assignment.     Suppose $f'(x) &gt; 0$ in $(a,b)$. Prove that $f$ is strictly increasing in $(a,b)$, and let $g$ be its inverse function. Prove that $g$ is differentiable, and that   $$g'(f(x)) = \frac{1}{f'(x)}$$   I have proven that $f$ is strictly increasing in $(a,b)$, and I could prove that $g'(f(x)) = 1/f'(x)$ if I could prove that $g$ is differentiable. The problem is that I am having trouble with a proof of that. Any advice?   Also, as a reference, this is exercise 5.2 from Baby Rudin. Renaming hundreds of files at once for proper sorting In shell scripts used for unit testing with dynamic libraries in a directory other than the typical @rpath, I have previously been able to set DYLD_FALLBACK_LIBRARY_PATH to set the directory containing the libraries. Under 10.11.1, bash seems to ignore attempts to set this environment variable:  $ sh -x testscript.sh + DYLD_FALLBACK_LIBRARY_PATH=/Users/something/testinglibs + export DYLD_FALLBACK_LIBRARY_PATH + exec printenv   and DYLD_FALLBACK_LIBRARY_PATH is not present in printenv's output.  Is this a security-related hack in 10.11's shell? I haven't been able to find this change documented in man pages or online. 18.04: color emoji not showing up at all in Chrome, only partially in Firefox The screen of my phone is physically broken, so it doesn't display anything, but the touch aspect does seem to be working, as I can unlock my phone, and get haptic feedback.  Before I go to get it replaced, I'd like to back up some personal data from the built-in memory to the SD card. I'm fairly certain that if I can get adb to recognize the device, then I can use  to see where I am touching the screen and do what I need to do. Problem is, when I plug it in, it's not recognized, while my emulator is.  I suspect that I might not have USB debugging enabled, which I think is necessary for adb to work. If this is the case, can someone give me screenshots of their Droid X (running 2.3.X) going from the home screen, through all the menus, to activating debug mode? Hopefully I can do it by dead reckoning and adb from there.  Edit: I haven't changed anything about the ROM or launcher; it's all stock. Safari can load internet but none of the other apps cannot! This is by far the weirdest problem I've come across,  My mac can perfectly access internet through safari web browser, but when I tried to do   ping www.google.com   through the terminal, it's requests is being timed out.  None of the other apps are able to reach internet either. Dropbox, Skype, Spotify all showing offline, except the browser itself  I'm guessing something bad with the DNS, but spend 2 hours trying to fix this with no luck Does anyone know what this probability question is asking? would this be considered a 'methodology' or a 'method'? Say I developed something called "Methodology for Establishing Remaining Life of Components". Basically, at work, we have components (or equipment). I wanted to develop a way to identify how much longer the components / equipment can last before they ware out and cannot be used.  It takes into account "the degree of damage currently in the component, the rate of future damage accumulation based on realistic operating scenarios, and the degree of damage required to cause failure." Taking these three into account, the remaining life of a component can be assessed. This is what I call "Methodology for Establishing Remaining Life of Components".   My question is, would this be considered a 'methodology for establishing remaining life of components' or just a 'method for establishing remaining life of components'? Or do you need more information to figure out if it is a method or methodology?   I cannot provide all the information for business purposes, but if additional  information is required to figure out if it is a method or methodology, I will provide it. I'm looking for a word that can describe a person who does nice things for other people (e.g holding the door open, carrying someone's things) but only for self gain; this person only does nice things to make themselves look good in the eyes of others, but doesn't actually care about the well-being of the people they're helping. A site URL changed and now its icon in SEDE is broken Making a Comment on a page without being on that page? I have a built a Wordpress site that enables comments on pages and I am using them as reviews, what I would like to do is for someone to be able to make a comment on a page without being on that page.    On the link above, the top right, there is a link that says have your say about a university, it would be good to have a HTML form and then a dropdown box of all the child pages of university-guide; which is where all the universities are stored, and then I can put my comments.php file into this.  So my HTML form appears and when a page is picked from a dropdown box, the comment will then be assigned to that page.  Any help or direction?
