Having two or more widgets, I am facing a problem where only the last updated instance of a widget is clickable.  I can refresh any widget with the refresh button, not open SE app by tapping the question.   Can be simulated by refreshing one widget and clicking the question on the second one. The SE app will not open.   Happens on various versions of Android (4.4, 5, 6.0.1) and various launchers, so it's not only a problem with my device
I have 4 copies of the Hot Questions widgets.  Sometimes, possibly after they reload on their own, I can only tap to open the last widget I added. If I tap on the question of any others nothing happens.  If I refresh each one then tapping works on the one I refreshed.
What's a common interjection for the reaction to something creepy and disgusting (like some insects or spooky places, etc.)? Happened on , fwiw. In particular I voted to reject it, then visited to add comment and vote to close, and wanted to add a  tag, but couldn't because had to wait to see the fate of the edit. Last two digits of $2^{1000}$ via Chinese Remainder Theorem? I bumped across the aforementioned question in my notes while studying today and I have completely forgot how to do this. I remember using CRT to solve a problem like this on one of my tests, too bad they didn't give back my solutions :(.  Since $\gcd(100,2) = 2$, we can't use the usual Euler's theorem to solve via $\pmod {100}$. So $100 = 5^2 2^2$, and applying Euler's on the 25 gives me $2^{20} \equiv 1 \pmod {25}$. However since $\gcd(2,4) = 2$, we can't do the same for $\bmod 4$. Accordingly how do I set up the other modulo congruence so I can apply CRT?

Ierator and for-each loop both we use for traverse no of items, I have used for-each many times but I am not clear about iterator, means when we should use ierator. I am studying salesforce workbook example..  global class CustomIterable implements iterator&lt;Account&gt;{    public List&lt;Account&gt; accs {get; set;}   public Integer i {get; set;}    public CustomIterable(){      accs =[SELECT Name fROM Account limit 5];      i = 0;              }   global boolean hasNext(){          if(i &gt;= accs.size()) {          return false;         } else {          return true;         }    }    global Account next(){          if(i == 8){return null;}          i++;          return accs[i-1];     } }   //------------  @isTest(seealldata=true) global class IteratorClass{     public static testmethod void main(){          IteratorClass obj = new IteratorClass();         Iterator&lt;Account&gt; acs =  obj.Iterator();         system.debug(acs);      }     global Iterator&lt;Account&gt; Iterator(){             return new CustomIterable();          }  } How do I convert a light circuit with a single pole switch to use two 3-way switches? I have a box in the hall which includes a 3-way switch (with another switch at the other end of the hall), a single pole switch to the garage lights and a single pole switch to the exterior lights on the garage.  The single pole switch to the garage is wired with a 3 wire plus ground. The white and black wires feed the garage lights from the switch and the red wire feeds the garage ceiling outlets and is hot all the time.  In the garage I would like to add a 3-way switch for the garage lights and another 3-way switch for the exterior garage lights.  In other words I would like to be able to turn on both of those light locations from both the inside hall and the garage as well. I know that I will of course have to replace the existing single pole switches in the hall with 3-way switches and add a junction box in the garage with 2 3-way switches in it.  The thing that I don't know is what wiring connections I need to make.  Can you help? I don't really know how to anticipate the changes in an option's price.  If I have an call set to expire the following Friday at $10 above the current share price, I know in the absence of other changes it loses value with each day that passes getting closer to its expiration. (Talking about American options.) But it gains value as the share price gets closer to the strike price.  So, if two days pass but the stock goes up $3, would the option have gained value or lost value? Is there any way to calculate this? How do I go about tracking down IO usage in Linux and other *nix OS'? Occasionally, something on my system starts hammering the disk. I would like to log data that would let me know about I/O usage per process, then I could go back to it later and see what keeps doing this. How should I go about solving this problem? Bonus points for solving this for arbitrary block devices. How do I add a .sty file to my MacTeX/TeXShop installation? I've searched online, but I have not found any clear instructions how to permanently add .sty files to my TeXShop installation. I'm using a Mac with OSX (TeXShop is a mac only program).  What is the best way of doing this? The one comprehensive set of instructions I found .   I've got as far as extracting the files (running LaTeX on the .ins and . dtx files) but after that I don't know what to do. I also don't understand how to update the index of my distribution, and whether there are particular OSX specifics (the instructions are for Windows). How to convert SSH public key from PEM to DER format?

I'm a bit confused in describing 1.5hrs in words.   Is writing one and a half an hour correct or should it be one and half hour?  E.g:     I'll see you there in one and a half an hour.     OR       I'll see you there in one and half hour.   Or is there any other correct way of writing this? Granting access only to standby database One of the physical standby databases in my environment is open in read-only mode and used for reporting purposes . I want to give users access only to this particular standby, not to primary db.   The best approach I found so far is to create AFTER LOGON ON DATABASE trigger which checks v$instance (or maybe v$database), and throws error for depends on  values of host_name/instance_role columns  .   I wonder if there is a better way to do it. How to secure recommendations and apply for PhD after having worked outside of academia for two years? The Bash command :(){ :|:& };: will spawn processes to kernel death. Can you explain the syntax? I looked at  and can't understand how this works.

On duplicate questions, I often see different headings for the duplicate question list. These include:     Possible Duplicate:    [duplicate question list]   and      This question already has an answer here:    [duplicate question list]   and more recently,     This question is an exact duplicate of:    [duplicate question list]   What decides which heading is placed before the duplicate question list? Example of a finitely generated faithful torsion module over a commutative ring Can a finitely generated module $M$ over a commutative ring have $\operatorname{Ann}(x) \neq 0$ for all $x \in M$ while $\operatorname{Ann}(M) = 0$?  It's not difficult to show that there is no such module if the ring is a integral domain. For general, I guess the answer is yes. But I failed to find a desired example.
