I come to stack overflow to ask specific questions and read the answers for specific questions. Sometimes I also answer a few questions. However, I noticed that since the "hot questions" drop down was implemented, when I check my inbox I sometimes spot an interesting question, click on it and get distracted. Before I know, I spend 20 minutes answering an unrelated question and another 20 minutes reading though existing answers and I have long forgotten the original question I googled. This means I spend way more time on stack overflow, than I would spend otherwise. Unfortunately, this also has a negative effect on the amount of work done.  When I work, I usually block facebook and reddit to prevent myself from being distracted. Since I started doing this, my productivity has increased a great deal. I always considered stackoverflow a work related website that didn't have this problem. Until "hot questions" came along.  I understand that "hot questions" is a nice feature to have when someone is browsing for interesting topics. It also drives traffic to the website by extending the time the average user spends on the site. However, as an end user who uses stackoverflow for work, I want to stay focused and minimize distraction.  Therefore, is it possible to disable the hot question button or make the inbox the default view? If not, is there any third party extension that I could use to hide it?  Edit: Wow, I didn't expect that this question would invoke such hostility. I think hot questions is a great feature when you're in "looking for interesting stuff" mode. But when you're in "getting things done" mode, it's a distraction. At least to me. I know that everyone on this site is perfect and never has looked at a youtube funny cat video during their work hours, but I must admit that I have. And it actually resulted in less work done. And to me it does help that youtube is blocked when I work, because I'm not perfect, and there's a chance that I would still end up there somehow in some way as it happened to me in the past a few times... and please don't get me started about facebook and reddit...
This may sound like a 'first world problem', but I am quite easily distracted by the 'Hot Network Questions' sidebar, as I find them quite amusing and some of them quite intellectual  But where the problem lies is that, even at work, if I google something up and find a solution on Stack Overflow, to some random problem I am working at, I (always) get distracted towards them (Hot Network Questions), and end up reading the whole Qs as well as As of that respective question, and this is adversely affecting my productivity.  Any suggestion would greatly help.
Study the following limit: $$ \lim\limits_{ (x,y,z) \to (0,0,0) } \frac{xy-z^2}{x^2+y^2+z^2} $$   I'm not sure if this way of proving that the limit does not exist is correct so I'm this is basically for a proof verification.  Approaching $(0,0,0)$ through the plane $z=0$, then the limit becomes  $$ \lim\limits_{ (x,y) \to (0,0) } \frac{xy}{x^2+y^2} $$  Now this limit does not exist, because approaching $(0,0)$ through the line $y=0$, the limit becomes  $$ \lim\limits_{ x \to 0 } \frac{0}{x^2} =0$$  But if we approach $(0,0)$ through the line $y=x$ we have that  $$ \lim\limits_{ (x,x) \to (0,0) } \frac{x^2}{2x^2}=\lim\limits_{ (x,x) \to (0,0) } \frac{1}{2} =\frac{1}{2}$$  So the limit $ \lim\limits_{ (x,y) \to (0,0) } \frac{xy}{x^2+y^2} $ doesn't exist. This means that the limit we began with doesn't exist, correct?

Input image strip without stretching to fit output frame When you add an image strip to the Video Sequence Editor, it stretches/shrinks your image to fit the full output frame.  How can I add an image at its original resolution?  For example, if I add a 60x60 pixel image, it should appear very small in the final 1080p render. If I write the following class:  public class Example {        int j;       int k;        public Example(int j, int k) {            j = j;            k = k;       }        public static void main(String[] args) {            Example exm = new Example(1,2);            System.out.println(exm.j);            System.out.println(exm.k);       }  }   The program compiles, but when I run the program, the main method will print out two 0s. I know that in order to say that I want to initialize the instance variables in the constructor I have to write:  this.j = j; this.k = k;   But if I don't write it, then which variable is evaluated (or considered) in the constructor (on the left and on the write hand side of the expressions)? Is is the argument or the instance variable? Does it make a difference?  Are there other cases where the use of this is obligatory? Prove $n-m \mid n^r - m^r\,$ [Factor Theorem, monomial case] In respect to a larger proof I need to prove that $(n-m) \mid (n^r - m^r) $ (where $\mid$ means divides, i.e., $a \mid b$ means that $b$ modulus $a$ = $0$). I have played around with this for a while now but to no avail and would be grateful if you could help me. What happened to Startups SE? I really enjoyed that site.

I have always wondered why diamonds shine. Can anyone tell me why? Novel about a guy who is possessed by the divine essence and the world ends? I read this novel back in the mid-80's but I'm pretty sure it was written in the 70's.  Strange things start to happen around a homeless man - like the laws of chance are changed.  The investigators discover that they can figure out what is going to happen next by interpreting the dreams/vision of the man.  One such dream is of a large body of water that is split into two pieces. Turns out that means that "C" (sea) - the speed of light has been halved.  The homeless man had become the embodiment of the creator essence. The creator was hiding, because it was tired of trying to keep the universe working and from the fight with is adversary - chaos.  At the end of the book, the creator allows the world to be destroyed and recreates it - except that planets are cubes and move in squares.  Yes - it was rather bizarre.

I'm an entry level programmer so please be descriptive in your responses.  I am trying to use a Java API given as a .jar file in my C# .net application.  I don't know much Java, but this .jar file says "no main-class manifest attribute" when I try to run it so this means its a library?  This Java API also comes with a .java file which shows how to use the library but I cannot see the code inside the .jar.  I found  on this site, and one of the answers reads, "In simple way you can pack your java classes to jar file then In C# use Process class for execute and map IO stream."  I am semi-familiar with the Process class in C# but I don't understand how I could use it to use a Java library in my C# .net project.  Is this possible? or was that answer incorrect?  If so, could you explain how I can use the .jar library in my C# app. When I double-click to select text in GNOME Terminal, the selection stops at spaces but continues over hyphens:      Some of my filenames contain uncommon characters such as the  and are not selectable by double-clicking:    Is there a way to make double-click selection continue over these characters as well?

I would like to know how to transform negative values to Log(), since I have heteroskedastic data. I read that it works with the formula Log(x+1) but this doesn't work with my database and I continue getting NaNs as result. E.g. I get this Warning message (I didn't put my complete database because I think with one of my negative values is enough to show an example):   &gt; log(-1.27+1) [1] NaN Warning message: In log(-1.27 + 1) : NaNs produced &gt;    Thanks in advance  UPDATE:  Here is an histogram of my data. I'm working with palaeontological time series of chemical measurements, E.g the difference between variables like Ca and Zn is too big, then I need some type of data standardization, that is why I'm testing the log() function.   This is my Is it OK to use a forward slash '/' between words other than the obvious 'and/or'? I don't want to get into the proper use of the phrase 'and/or', but rather to investigate the use of the forward slash between other words. Examples:   I have an interview with him/her this afternoon. He has a large binder/notebook.   And even separating just letters:   I connected the i/o ports. (input/ouput) Mark the field as n/a. (not applicable) I did it w/o her help. (without)   It seems as thought the forward slash can be used to indicate an option, display ambiguity, shorten 2 words and shorten 1 word (and others).  Is it OK to use a slash to separate these words/letters (yes, that was intended), or is it better to explicitly say 'his or her'? One more thing, is it correct to 'chain' these phrases together? I'm horrible with examples but here's one:   I don't open letters/mail that aren't/isn't addressed to me. What are the difference between the following sentence?    I ate apples.

Can't unhide grayed out objects After some searching on stack / google I decided to ask this here, this is the second time I'm facing this issue this time with blender 2.8, previously with 2.7 and without a clue to how I got here.  Some of my objects appear hidden(10/12), and I can't seem to find a way to unhide them.  Solutions to the most common rookie mistakes seems to be   In local-view solved by pressing numpad / hidden by pressing H or Shift + H, unhiding with Alt + H   I'm not in local view, I can toggle visibility for 2/12 objects with Shift + H &amp; Alt + H, but the rest stays gray in the collection.  Last time I solved this by exporting the whole model as STL and importing it back again, I then had to re-group all the pieces but there must be a more simple solution.
