Yesterday,  I don't know how but i got up vote in all  my questions and answer in Mathematics, Physics, Chemistry and Ask Ubuntu Stack Exchange. Due to i got total around +310 reputation.   Today that serial voting was revised in Mathematics and Physics S.E. So I want to know which user has done this serial voting, Is it possible?
Is it possible to know who voted my question/answer up or down? If not, then is it possible to include this feature? By this feature we can come to know if you are being voted up by question owner or persons giving other answers to same question or just the visitors of that question thread.  Like...  If it is a group of people giving other answers, then your answer is most correct If it is readers of that question, then your answer is more popular

Prove that if a function $f: X\to Y$ continuous then its graph is closed Discount for Roles I am using Drupal Commerce and I would like to know if it is possible to have discounted prices for registered users and much better for roles.  For example, the nomral price is $100 but when a user logs in that belongs to Role1 for example, he will see different prices with the percentage discount that I will have assigned to that role.  How can I accomplish such a feature? When is the graph of the divisor relation on $[n]$ planar? In what order should one apply max HP reduction and damage? A character at 10/26 HP is hit by a Wraith and fails the Constitution saving throw. They take 21 damage and their maximum HP is reduced to 5.  Are they unconscious because the 11 excess damage is less than 26 or dead because it's greater than 5? There have been several questions already posted with specific questions about , such as when to use it and what frameworks are there for it. However,  What is dependency injection and when/why should or shouldn't it be used? Are any of the alien languages in Star Wars real Earth languages?

How to determine function name from inside a function Is there anything I can do about someone who has pointed their domain at my ip? This is kind of a weird request. For some reason whoever owns safeandbuy.com has pointed their domain at my IP address. The reason it's a problem is that I'm having all kinds of crawlers that are trying to crawl my site with that domain name.   Is there anything I can do about this? How do I get a Cron like scheduler in Python? How to "pretty" format JSON output in Ruby on Rails I would like my JSON output in Ruby on Rails to be "pretty" or nicely formatted.   Right now, I call to_json and my JSON is all on one line.  At times this can be difficult to see if there is a problem in the JSON output stream.  Is there way to configure to make my JSON "pretty" or nicely formatted in Rails? Connection pools being reset with Error: 18056, Severity: 20, State: 46. & Perfmon Counters not showing We are using SQL Authentication (to reduce the number of connection pools) &amp; .NET 4.0 connection strings to connect to SQL Server Enterprise Edition 2012 SP1 on a Windows 2008 R2 Enterprise Server:     Microsoft SQL Server 2012 (SP1) - 11.0.3000.0 (X64)   Oct 19 2012 13:38:57   Copyright (c) Microsoft Corporation   Enterprise Edition (64-bit) on Windows NT 6.1  (Build 7601: Service Pack 1)   We use about 50 servers split into 8 different groups different parts of a website.  Our website is using this SQL Server to log visit tracking data. Over the last few days it has spat out the following messages about the resetting connection pools:     The client was unable to reuse a session with SPID 1327, which had been reset for connection pooling. The failure ID is 46. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.   Error log reads:     Error: 18056, Severity: 20, State: 46.   The client was unable to reuse a session with SPID 959, which had been reset for connection pooling. The failure ID is 46. This error may have been caused by an earlier  operation failing. Check the error logs for failed operations immediately before this error message.   Login failed for user 'xxxx'. Reason: Failed to open the database 'xxxxxxxx' configured in the login object while revalidating the login on the connection. [CLIENT: 10.xx.xx.xxx]   After some digging, I found this document on the CSS blog:  and this one by Aaron Bertrand: . I know the error number is different but the failure ID is the same with a number of the messages are identical).  Failure ID 46 suggests that the login did not have permissions. Our logins default to the master database and the db name is specificied in the connection string.  I wanted to check the number of connection strings pools, etc. and checked all the counters in Perfmon for .Net Data Provider for SqlServer. It only gave me the option of defaultdomain9675 for the instance, so I selected that assuming that is a system generated ID name for our Datacentre network. Unfortunately all of the counters are reading zero. On one of our other main servers the connection pools are hovering around 10 which is what I expected to see on a healthy server with that kind of load.  My question is 3 fold   Can anyone suggest why the Windows 2008 R2 Server is not showing .Net Data Provider for SqlServer? Has anyone experienced this as I obviously believe that the login not having permissions is a red herring ? If different groups of web servers have the same connection string syntax but with slightly different whitespace, would this cause the server to use another connection pool?   Min &amp; max memory settings are 20GB &amp; 58GB respectively. The server is a dedicated database server with 64GB of RAM. I don't think memory is the issue as the box seems to have a decent page lfe expectancy. Auto close is not enabled. The server is always up: this is a 24x7 website with heavy usage. PHP conditionals, brackets needed? I was just browsing a forum and someone asked about a PHP file they had found on the web.  It has several spots like this in the code:  if ($REMOTE_ADDR == "") $ip = "no ip"; else $ip = getHostByAddr($REMOTE_ADDR);  I have always thought brackets are needed to enclose what you want to do if the condition is true.  Is there some other alternative, such as if it is on the same line you don't?  There is also another line like this: if ($action != ""): mail("$adminaddress","Visitor Comment from YOUR SITE",  My instinct is to say this wouldn't work, but I also don't know if it is an outdated PHP file and it used to work? I tried using integration by parts twice, the same way we do for  $\int \sin {(\sqrt{x})}$ but in the second integral, I'm not getting an expression that is equal to  $\int x\sin {(\sqrt{x})}$.  I let $\sqrt x = t$ thus, $$\int t^2 \cdot \sin({t})\cdot 2t dt =  2\int t^3\sin(t)dt = 2[(-\cos(t)\cdot t^3 + \int 3t^2\cos(t))] = 2[-\cos(t)\cdot t^3+(\sin(t)\cdot 3t^3 - \int 6t \cdot \sin(t))]]$$  which I can't find useful. "ping: unknown host google.com" but IPs works fine Can't run gparted in fresh system Trying to run gparted in fresh installed Ubuntu. System not found this program. When I try to install I have report that it is already installed. How to solve this problem?  g@g-Lenovo:~$ gparted The program 'gparted' is currently not installed. You can install it by typing: sudo apt install gparted g@g-Lenovo:~$ sudo aptitude install gparted [sudo] password for g:  gparted is already installed at the requested version (0.25.0-1) gparted is already installed at the requested version (0.25.0-1) No packages will be installed, upgraded, or removed. 0 packages upgraded, 0 newly installed, 0 to remove and 130 not upgraded. Need to get 0 B of archives. After unpacking 0 B will be used. Let $(B_t)_{t\geq 0}$ be a standard Brownian motion in $\mathbb{R}^d$. It is intuitive that, for fixed $s&lt;t&lt;u$  $$\mathbb{E}[B_t\mid \sigma(B_s,B_u)]=B_s+\frac{t-s}{u-s}(B_u-B_s).$$  However, I cannot think of a way to show this rigorously.   If first attempted to take $A\in\sigma(B_s,B_u)$ and show that $\mathbb{E}[1_A B_t]=\mathbb{E}[1_A(B_s+\frac{t-s}{u-s}(B_u-B_s))]$. But I cannot manage to show this equality.   I'd be very thankful for any ideas and suggestions on how to tackle this problem. Can someone explain the dollar sign in Javascript?
