In Overwatch, a player can be issued medals for peak performance in 4 categories; Eliminations, Damage, Healing, and Objective Time, and Objective Kills. Bronze, Silver, and Gold medals are awarded for 3rd, 2nd, and 1st in that category, respectively.  How is EXP gain calculated from these medals? What are the specific EXP numbers gained from the different categories of medals? Will multiple Gold medals stack their EXP? Can EXP from multiple categories of medals stack, or is only the highest achieved counted?  All this time playing the game, and I still don't know how medals work...
At the end of the game, how are medals awarded?   As a secondary, what is the relation between bronze silver and gold medals, and how much experience do they reward?
How can I set desktop defaults for new users? How can I set up desktop defaults, much like most distributions do, for every new user? (ex. default wallpaper, apps, etc) Assume  $$G_1=\mathbb Z_5 \times \mathbb Z_{5^2}\times \mathbb Z_{5^3}\times \mathbb Z_{5^4} \times\ldots$$ $$G_2= \mathbb Z_{5^2}\times \mathbb Z_{5^3}\times \mathbb Z_{5^4} \times \ldots$$ How do I prove $G_1$ and $G_2$ aren't isomorphic? I asked  this question here  and I received tree answer, but the answer of Ludolila will be complete when  $G_1$ and $G_2$ are not isomorphic.    Thanks in advance Proving the series $\sum_{n=0}^{\infty}\sin(e\pi n!)$ converges OS X El Capitan installation error: AMD-Action:authenticate:SP When doing a clean re-installation of El Capitan (highest supported version) from a bootable USB on an older Mac (MBP, 15-inch, Late 2008), I get this error:  An unexpected error occured while signing in.

I'm an Indian student currently in Singapore as a Research Associate with a TEP valid for five months and have just been selected for an internship in Switzerland this summer.  Is it possible for me to obtain a Schengen visa from the Swiss Embassy in Singapore? I have a Laars gas boiler that has 3 heating zones. I want to replace the old mercury honeywell tstat on the 1st floor (heat only) with a newer honeywell RTH9580 wifi model. I've taken pictures of my entire system, labeled the wires in the pics to indicate the associated connections, and included the Laars wiring diagram.  There is a transformer mounted on the wall near the boiler that is wired in-line to the system (power from the panel --> into the emergency boiler switch --> into the wall transformer --> then to the boiler (low water cut off and boiler circuitry).  There is also a transformer within the boiler circuitry itself.  Can someone tell me the best method (proper preferred, not necessarily easiest) to connect the C wire? Can I use a 23 W CFL in a fixture that's rated for a 60 W incandescent? I have a lamp that is rated at 60 Watts for an incandescent bulb with a disclaimer to use a 13 Watt bulb instead when using a CFL replacement. Do I really need to respect that disclaimer? Would not a 23 Watt CFL be just as safe to use? It still draws less power than a 60 Watt incandescent, right? Removed Python 3 and now Ubuntu Software Center, terminal and other applications don't work I am a new Ubuntu user running Ubuntu 13.04.  I've been trying to install and use a DeDRM tool, but I've been having problems doing so. I was following some directions that said I needed a version of Python 2.7, but not anything Python 3.0 or later (because 3.0 versions are missing some necessary libraries?). I tried to install Python 2.7.5.6, but it didn't work. I thought it was probably because I had the later version of Python, so I went through terminal and removed Python 3.3, so I could install the earlier version of Python.  Now that I've uninstalled Python 3.3, a lot of applications no longer work, including the terminal and the Ubuntu Software Center. I have no idea how to fix this problem now. How does time work in The Matrix? How to format numbers as currency strings I had some NEF files in a folder that I didn't do anything with. When importing them in Lightroom, no previews and a "file unsupported or damaged message" So I tried with Nikons ViewNX, nothing. Even not in DxO or PhotoMechanic.  I had a look with EXIFTool and the corrupt file prints me only this:  ExifTool Version Number         : 8.39 File Name                       : _DSC5559.NEF Directory                       : /Users/tunafish/Desktop File Size                       : 12 MB File Modification Date/Time     : 2010:11:29 12:46:56+01:00 File Permissions                : rwxrwxrwx Error                           : File format error   I saw another question on photo.stack  and tried to copy over the makernotes from a good file (_DSC5556.NEF) with  exiftool -tagsfromfile _DSC5556.NEF -makernotes _DSC5559.NEF   but EXIFTool gives me this error  Error: Not a valid TIFF - _DSC5559.NEF 0 image files updated 1 files weren't updated due to errors   I have uploaded 2 NEF's, with _DSC5559.NEF being the corrupt one here: Im trying to run the following code  \documentclass[border=10pt]{standalone} \usepackage{pgfplots} \pgfplotsset{width = 7cm, compat = 1.8} \begin{document} \begin{tikzpicture} \begin{axis}[domain = -2:2, domain y = 0:2*pi] \addplot3[contour gnuplot = {output point meta = rawz, number=10, labels=false}, samples = 41, z filter/.code=\def\pgfmathresult{-1.6}] {exp(-x^2) * sin(deg(y))}; \addplot3[surf, samples = 25] {exp(-x^2) * sin(deg(y))}; \end{axis} \end{tikzpicture} \end{document}   and I'm getting the error  Package pgfplots Error: sorry, plot file{Utitlled_contourmp0.table} could not be opened   through a quick search I found out that contour maps require pgfplots and gnuplot to talk to each other. In theory the way to make them interact is adding  !TEX option = --enable-write18   or   %!TEX option = --enable-escape   at the top of the file. Unfortunately this has not worked for me. Any suggestions? Can you use a readied action to teleport out of the way of a weapon attack? Let's say that a player uses the ready action and says "If a character aims at me with a weapon, I'll use Teleport to move behind cover."  What happens? Does this work? If not, please cite the rules to explain why not. One of the most common security best practices these days seems to be . I've never really found a good explanation for that, but I'm assuming it's to minimize the risk of a  malicious or infected script within the webroot from reading the database password.  But, you still have to let WordPress access it, so you need to expand open_basedir to include the directory above the document root. Doesn't that just defeat the entire purpose, and also potentially expose server logs, backups, etc to attackers?  Or is the technique only trying to prevent a situation where wp-config.php would be shown as plain-text to anyone requesting http://example.com/wp-config.php, instead of being parsed by the PHP engine? That seems like a very rare occurance, and it wouldn't outweigh the downsides of exposing logs/backups/etc to HTTP requests.  Maybe it's possible to move it outside the document root in some hosting setups without exposing other files, but not in other setups?    Conclusion:  After a lot of back-and-forth on this issue, two answers have emerged that I think should be considered the authoritative ones. Aaron Adams makes a good case in  wp-config, and chrisguitarguymakes a good . Those are the two answers you should read if you're new to the thread and don't want to read the entire thing. The other answers are either redundant or inaccurate. I was using Windows XP, I like Ubuntu, but I'm wondering,because as  I'm a professional photographer &amp; photo editor.

(Reference : Fraleigh, A first course in abstract algebra)     Prove that a nonempty set $G$, together with an associative binary operation * on $G$ such that $a*x=b$ and $y*a=b$ have solutions in G, $\forall a,b\in G$, is a group.   Because * is an associatie operation, we have to prove that: there exists $e\in G$ such that $e*a=a=a*e$ for any $a\in G$, and that for any $a\in G$ there exists $\alpha \in G$ such that $a*\alpha=e=\alpha *a$.  This is very confusing, first I tried to prove the identity exists. If we consider a=b, then $a*x=a=y*a$, and because of the hypothesis $x,y\in G$ always exists, now we have to show that $x=y$, but I just can't do this with out inverses, so I tried to prove that the inverses exists, however I have no idea how the identity looks like, I'm stuck.  And I tried to get unstuck, so I thought particular cases, first if $G$ had only one element, then what would happend if it had just two elements... but I remembered that we don't know if G is finite or not, and I think this makes things a little bit more complicated.

A friend recently got her ID stolen while she was in the Netherlands. She will soon need to fly to her home country Italy, but she doesn't know what to do.  What can one do in such a situation? As far as I know, since it's Schengen, you don't need an ID card to go through borders. On the other hand, this is air travel, so they always require it for security reasons.   Can she show another document that proves her nationality? A copy of the ID card? Anything?
