Does voting count work on mobile site of stackoverflow? I have gotten the  on Stack Overflow, and I visited a lot of downvoted and upvoted posts on Stack Overflow on the mobile site, but I can't see number of upvotes and downvotes.  Does the mobile site not support it?
Show the number of up-votes and down-votes on the mobile site theme It seems we can't view the number of up-votes and down-votes a question has from the mobile site. Can this be added or is there a reason it isn't available?
Suppose you have 2 circles that intersect each other in such a way that each circle passes through the other's center. What is the area between the circle(or common area) i.e. area between the centres of the circles? divisor of a product of integers is a product of divisors I read this recently on the web and can't manage to understand it. Not homework -- I haven't done math homework for years.  If $d\mid ab$ then $d=d_1 d_2$, that $d_1|a$, that $d_2|b$ and, further, if $(a,b)=1$ then $(d_1,d_2)=1$.  I know it's the same question... if $a = a_1 a_2 ... a_n$, why can't $d$ divide some $a_i$ and only $a_i$? How to fix "W: Duplicate sources.list entry"? What is the meaning of this "let there be light" joke? The difference between 'credit' and 'accredit'? Both verbs seem to mean the same thing -- to attribute 'X' to Mr. 'Y'. On looking it up, I found:  credit - publicly acknowledge a contributor's role in the production of (something published or broadcast).  accredit - give credit to (someone) for something.  Am I overthinking this, or is there really a difference I should know of? Suppose the mean noon-time temperature for September days in San Diego is 24∘ and the standard deviation is 4.9. (Temperature in this problem is measured in degrees celsius)  On September 26, 1963, the all-time record of noon-time temperature in San Diego of 44∘ was hit. Assume the temperature distribution is symmetric around the mean, what is the Chebyshev bound for the probability of breaking (or tieing) this record?  I am having a hard time understanding this. Could someone explain to me how to do this? Gendry was born in the Crownlands and should therefore be referred to as Gendry Waters. However, he refers to himself as Gendry Rivers.   Did showrunners forget or is Gendry ignorant of the customs? Retrieve Voice Memos from device? iOS seems to refuse to allow me to email "long" voice memos, and I'm unaware of any way to extract them from iTunes backups of my phone. How can I retrieve entire voice memos that aren't really short? What are your tips for improving overall system performance on ubuntu? Inspired by this  I realized that some default settings may be rather conservative on Ubuntu and that it's possible to tweak it with little or no risk if you wish to make it faster.  This is not meant to be application specific (e.g. make firefox load pages faster), but system wide.  Preferably 1 tip per answer, with enough detail for people to implement it.  A couple of mine would be:   Install  (via Software Center or sudo apt-get install preload); Change  value - "which controls the degree to which the kernel prefers to swap when it tries to free memory";   What are yours?  PS: Since this is not intended to have a unique answer but rather, several useful tips, I'm making this community wiki out-of-the-box. How can I detect mouse events on sprites in a canvas? I'm making an HTML 5 game. I want mouse clicks on sprites drawn in a canvas element cause events that my code can react to. At the moment, I'm doing it by checking through all of my sprites in a for-loop on each click.  Is there a way to do that by adding an event listener to a sprite so it would respond just like that?  Are Javascript's custom events useful in this situation? I know it's possible with KinectJS, but I don't have any experience with it and really I'd like to learn how to do this myself without the help of a library. What is the difference between == and equals() in Java? When performing machine learning, the performance of the machine learning method is dependent on the original function $f$ that we are trying to learn (let's forget for a moment the non-deterministic error and focus on the properties of $f$).  I have a conceptual question. What would make a function easy to learn? For instance, a linear function can be easily learnt by linear methods such as linear regression and SVM. But in the general case, what would make a function easier to learn for decision trees or a neural network?   I believe feature engineering helps us move to a feature space in which the function we want to approximate is easier to represent. But what properties exactly are we trying to achieve for this function? Coding for an ordered covariate I am performing ordinal regression, I have 5 response categories and several predictors both continuous and categorical. I would like to add a predictor which is categorical but ordered (1, 2, 3, 4). I don't think it would be appropriate to apply the usual dummy coding for unordered categorical predictors, but when I searched for how to code this I did not find much information.  In  "linear coding" or "assuming linearity of the predictor effect" is mentioned, but without further details.  Does it mean I just use my ordered values as they are, i.e. use them as a continuous variable? I want to do something like:  MyObject myObj = GetMyObj(); // Create and fill a new object MyObject newObj = myObj.Clone();   And then make changes to the new object that are not reflected in the original object.  I don't often need this functionality, so when it's been necessary, I've resorted to creating a new object and then copying each property individually, but it always leaves me with the feeling that there is a better or more elegant way of handling the situation.  How can I clone or deep copy an object so that the cloned object can be modified without any changes being reflected in the original object? public static map&lt;id,RecordType&gt; MapRecordtype = new Map&lt;id,RecordType&gt;([SELECT id, DeveloperName FROM RecordType where sobjecttype ='move__c' and                                         Developername in('Assignment','Draft','Domestic_Draft','LTST_Draft','MX_Domestic','MX_Domestic_draft','Termination','International_Relo','Localization','J1',                                        'Back_To_Back','Repatriation','PAM','US_Domestic_Relo','CHN_Domestic_Relo','CHN_Domestic_Draft')])   Can we write schema for above query? What's the 1 inch square knob sticking out of the wall? ATI Radeon HD 7770 no GPU rendering? MySQL Insert query doesn't work with WHERE clause What's wrong with this query: INSERT INTO Users( weight, desiredWeight ) VALUES ( 160, 145 ) WHERE id = 1;  It works without the WHERE clause. I've seemed to have forgot my SQL. How do I delete folders and files that were older than 7 days on the command line? I want to delete folders and its files were created longer than 7 days using the command line. Getting a System.Type from type's partial name I want to get a System.Type given only the type name in a string.  For instance, if I have an object:  MyClass abc = new MyClass();   I can then say:  System.Type type = abc.GetType();   But what if all I have is:  string className = "MyClass";
