I was wondering if the Stack Overflow developers had created a bookmark page where all of my favourited questions will be displayed.  This page should also have a quick way to search its contents. I think that would be helpful to everyone.
What does bookmarking a question mean? How do you bookmark a question? Do users get updates on their bookmarked questions? Are my bookmarks publicly visible? How do you see your own bookmarks? How do you see other users' bookmarks? How do you see which users have bookmarked a particular question? What impact does the bookmark system have on the voting system? Can I &quot;un-bookmark&quot; a question? Can I search within my bookmarks?
What is meant by "Constant Amortized Time" when talking about time complexity of an algorithm? How can I use Web.debug.config in the built-in visual studio debugger server? Do we use abstract algebra in real life? Do we use abstract algebra in real life?   Is there any application of abstract algebra in real life? List user's folder access permissions JSON and escaped double quote I'm currently making a callout to a 3rd party vendor and I'm getting a huge response. What is currently messing me up is this section:   "MessageSeq":13,"Description":"config file: config-qa1.txt\"","MessageTS":"2014-02-17T14:46:58","MessageLevel":4,"IsSystemMessage":false   As you can see here, the portion at the end of the Description value is ended with backslash double quote. If I attempt to parse this via the JSONParser I get an exception. Does anyone have an recommendations on how to resolve this?

I am trying to find its real solution.  I was trying in this way!! $$6^x\left( \frac {4^x}{6^x} + 1\right) = 9^x$$ $$\left({\frac 23}\right)^x +1=\left({\frac 32}\right)^x$$ but I'm stuck . . . Will anyone help ? How do i show that $w=z^2$ maps $|z-1|\leq 1$ onto the cardioid $R=2(1+\cos \theta)$? Problem installing .deb in Software Install Ubuntu 20.04 I tried to install some .deb files in Ubuntu 20.04 from GitHub and other internet sources, but when I open it with Software Install it gives me  problem (Failed to install file: not supported). The only way for me to install them is to go to the downloaded file and do sudo dpkg -i file.deb. Can anyone help? I don't know what to do and I don't want to use the terminal every time. Any help would be appreciated, thanks EDIT: that's NOT a problem with .deb in Ubuntu, it is a problem with Software install. I can install every .deb through the terminal but not with Software install, and Ubuntu suggests to install .deb with Software install. That's not a dependencies problem or anything similar, that's an issue with installing .deb WITH Software install and I would like to know how I can fix Software installer How do I change fonts and adjust their size? I've been finding fonts on the internet and  on my system.   What's the easiest way to change my fonts? I would prefer an easy to use graphical way, but answers with command line recommendations are also welcome. Why does an argument similiar to 0.999...=1 show 999...=-1? Use of 'const' for function parameters How far do you go with const?  Do you just make functions const when necessary or do you go the whole hog and use it everywhere?  For example, imagine a simple mutator that takes a single boolean parameter:  void SetValue(const bool b) { my_val_ = b; }   Is that const actually useful?  Personally I opt to use it extensively, including parameters, but in this case I wonder if it's worthwhile?  I was also surprised to learn that you can omit const from parameters in a function declaration but can include it in the function definition, e.g.:  .h file  void func(int n, long l);   .cpp file  void func(const int n, const long l)   Is there a reason for this? It seems a little unusual to me. I have one bash source run.sh as follows,  #!/bin/bash if [ $# -ne 1 ]; then     exit fi ...   when I execute it in two ways, there are different behaviors. The first way is,  source run.sh   It will close the terminal after execution. The second way is,  ./run.sh   this will simply finish running the script, and stay on the terminal. I am asking if there is a command for exiting a bash scripts for both source run.sh and ./run.sh execution. I have tried return too, which does not work well under ./run.sh execution.  More generally, I am interested in why this is happening, and what's difference between using "source" and "." for script execution? Can it hurt to put my GRE score on my resume? If my score is good and if I'm applying for an MS program in Europe, can it give me any kind of edge? The university I'm applying to requires GRE scores for certain programs but not the one I'm applying for. And if it won't be advantageous, can it hurt my prospects in anyway? Can open sets and closed sets of $\mathbb{R}^n$ be homeomorphic? Suppose $A$ is an open subset of $\mathbb{R}^n$ considered as a topological subspace. Suppose $B$ is a another susbet of $\mathbb{R}^n$, and under the induced topology, is homeomorphic to $A$.  If $B$ is closed and bounded, then by the Heine-Borel theorem, $B$ is compact as a topological space so $A$ and $B$ cannot be homeomorhpic, because $A$ is not compact. But if $B$ is not bounded, what can be said about $B$, if any? Must $B$ be open, can it ever be closed (let's leave out the only case of being both open and closed--the entire ambient space $\mathbb{R}^n$), or can it be neither open nor closed? Novel about alien conquerers who conduct games to select servants I read this maybe 10-15 years ago.   Aliens have conquered earth. Possibly quite some time before the time then novel is set in. They have built their own cities. They conduct periodic athletic competitions for humans similar to the current olympics. The winners are take into the city to act as servants to the masters. The protagonist is part of a human resistance movement who is competing in the games. The plan is to infiltrate the city, gather intel and escape. He wins, get in, finally has to kill his master and escape down a waste disposal system which ends up outside the city.   Anybody knows which one I am talking about? In JavaScript can I make a "click" event fire programmatically for a file input element? I'd like to make a click event fire on an &lt;input type="file"&gt; tag programmatically.  Just calling click() doesn't seem to do anything or at least it doesn't pop up a file selection dialog.  I've been experimenting with capturing events using listeners and redirecting the event, but I haven't been able to get that to actually perform the event like someone clicked on it. How Deep Are Bender's Insides? Bender often pulls large objects from his torso cupboard, but how deep or how much empty space is he capable of storing? Can he bend space around the perimeters of the frame of his torso's door? If that is the case, does it also bend time? I suppose he might bend in more ways than one... Unable to start XAMPP using sudo in Desktop Entry I am using Ubuntu 18.04. I have installed XAMPP and created a .desktop file to run it.

It was created using knife tool and lots of clicking:    What would be the best way to randomly generate such cuts with less effort...? Same Video on each face, but with different time delay? iam looking for a way to - like the title says - i want to put the same video on each face, but with different time delay.  In other words, i want to create a kind  of videowall.  i found :  #---------------------------------------------------------- # File multi_material.py #---------------------------------------------------------- import bpy  def run(origin):     # Create three materials     red = bpy.data.materials.new('Red')     red.diffuse_color = (1,0,0)     blue = bpy.data.materials.new('Blue')     blue.diffuse_color = (0,0,1)     yellow = bpy.data.materials.new('Yellow')     yellow.diffuse_color = (1,1,0)      # Create mesh and assign materials     bpy.ops.mesh.primitive_uv_sphere_add(         segments = 16,         ring_count = 8,          location=origin)     ob = bpy.context.object     ob.name = 'MultiMatSphere'     me = ob.data     me.materials.append(red)     me.materials.append(blue)     me.materials.append(yellow)      # Assign materials to faces     for f in me.faces:         f.material_index = f.index % 3      # Set left half of sphere smooth, right half flat shading     for f in me.faces:         f.use_smooth = (f.center[0] &lt; 0)  if __name__ == "__main__":     run((0,0,0))   But it didn't really work out for me, it creates a red sphere and sends      Traceback (most recent call last):   File "\Text", line 36, in      File "\Text", line 28, in run AttributeError: 'Mesh' object   has no attribute 'faces' Error: Python script fail, look in the   console for now...   to the console. Also i didn't know how i could add the delay in there.  Hope you can help me out with this! :)
