In Linux Mint pressing the Alt+LMB moves windows. How would I select an edge loop in this situation?
I am trying to use the Alt+Right Click to select edge loops in Linux Mint but this shortcut doesn't work it is already used for Linux to reduce a window. I have checked the keyboard shortcut but it doesn't appear.
How can I completely remove NetworkManager? Multiple submit buttons in an HTML form Let's say you create a wizard in an HTML form. One button goes back, and one goes forward. Since the back button appears first in the markup when you press Enter, it will use that button to submit the form.  Example:    &lt;form&gt;   &lt;!-- Put your cursor in this field and press Enter --&gt;   &lt;input type="text" name="field1" /&gt;    &lt;!-- This is the button that will submit --&gt;   &lt;input type="submit" name="prev" value="Previous Page" /&gt;    &lt;!-- But this is the button that I WANT to submit --&gt;   &lt;input type="submit" name="next" value="Next Page" /&gt; &lt;/form&gt;     I would like to get to decide which button is used to submit the form when a user presses Enter. That way, when you press Enter the wizard will move to the next page, not the previous. Do you have to use tabindex to do this? What can I do if I forgot my Windows password? Can I use set instead of List to resolve the duplicate id issue If you take a look into this issue     I have provide an answer of using set&lt;Sobject&gt; instead using list&lt;Sobject&gt;  i.e.  if( !contacts.values().isEmpty() ){   set&lt;Contact&gt; setContacts = new set&lt;Contact&gt;();   for( Contact objCon : contacts.values() ){     if(!setContacts.contains(objCon)){         setContacts.add( objCon );     }   }  update new list&lt;Contact&gt;(setContacts); }   even if(!setContacts.contains(objCon)) is not needed  if( !contacts.values().isEmpty() ){   set&lt;Contact&gt; setContacts = new set&lt;Contact&gt;();   for( Contact objCon : contacts.values() ){         setContacts.add( objCon );   }  update new list&lt;Contact&gt;(setContacts); }   So is there any condition/use case where this answer might fail? An error of Graphing Calculator Desmos? Can someone explain to me this error of the Desmos graphic calculator? Why ? For other values of $x$, the exact value of $f(x)$ is obtained.  Or am I wrong when I assure that $f(\sqrt2)=0$? Which of the following two sentences is correct?  He must decide who to be. He must decide whom to be.  I can think of arguments for both sides, but I'm not sure. To elaborate, is who(m) the object of decide, the subject of be, or the object of be? Does the infinitive form of be have any bearing on the answer? And is there anything else to consider about the position or role of who(m) in this particular sentence that would inform the answer? The answers to the linked question  say to &quot;substitute he and him for who and whom.&quot; However, that doesn't give a clear answer in this context, because neither of those pronouns sounds right: &quot;He must decide to be he&quot;? &quot;He must decide to be him&quot;? Normally we'd use a reflexive pronoun here (&quot;He must decide to be himself&quot;) and it's not clear what case that corresponds to. I've recently embarked on my PhD studies (cancer, structural biology) and have yet to publish. Currently, there are some 200 papers in my name and several thousand under my surname. Because of this, I am considering switching my surname to an old, rare, surname in my family, which is only used by one active researcher.  My question is this: are there any reasonable alternatives that does not include legally changing my name? I personally don't mind changing it, but the old surname happens to be "noble", and may come off as quite pretentious. I would be able to change to another, less pretentious, surname, but in terms of rareness, no alternative comes close.   In short, what are my alternatives? I am using Ubuntu 17.10 on my desktop PC, I've been monitoring network traffic with Etherape. I noticed HTTP requests from my PC(casa hostname) to googleusercontent.com (104.198.143.177). So I used lsof and ss to 'identify' process behind these requests.    Using lsof -i:   NetworkMa  778            root   20u  IPv4 546772      0t0  TCP casa:53671-&gt;177.143.198.104.bc.googleusercontent.com:http (SYN_SENT) NetworkMa  778            root   20u  IPv4 546772      0t0  TCP casa:53671-&gt;177.143.198.104.bc.googleusercontent.com:http (ESTABLISHED)   Using ss -rep dst 104.198.143.177:    tcp    SYN-SENT   0      1      casa%enp4s0:53671    177.143.198.104.bc.googleusercontent.com:http  users:(("NetworkManager",pid=778,fd=20)) timer:(on,964ms,0) ino:546772 sk:6df &lt;-&gt; tcp    ESTAB      0      87     casa%enp4s0:53671    177.143.198.104.bc.googleusercontent.com:http  users:(("NetworkManager",pid=778,fd=20)) timer:(on,300ms,0) ino:546772 sk:6df &lt;-&gt;   It seems NetworkManager (pid 778) is sending requests to googleusercontent, and it happens every 5 minutes exactly.   I have to say, no applications were launched at the moment, no background process, no network activities,no online account and it was a 'Ubuntu fresh install'. So why NM would sent requests to googleusercontent? I'm trying to factorise $$ x^3z - x^3y - y^3z + yz^3 + xy^3 - xz^3 $$ into four linear factors.  By plugging it into WolframAlpha I've learned that it's $$-(x-y)(x-z)(y-z)(x+y+z)$$  My question is: what are the steps involved in factorising the expression? Is there a method I don't know about that I'd have access to with my limited maths?  Really appreciate any help! Calculate the sum of inverse values of ${n\choose 0}, {n\choose 1}, ... {n\choose n}$ Calculate $$A={1\over {n\choose 0}}+ {1\over {n\choose 1}}+ ...+{1\over  {n\choose n}}$$  and  $$B={1\over {n\choose 0}}- {1\over {n\choose 1}}+ ...+{(-1)^n\over  {n\choose n}}$$     My idea for $A$ is some probabilistic reasoning. Color the sets $$\{\}, \{1\}, \{1,2\}, \{1,2,3\},...\{1,2,...,n\}$$ and ask our self what is the probability that I choose colored set among all sets. Clearly this is exactly ${n+1\over 2^n}$ and on the other side it is $A$:  probability that I take empty set is ${1\over {n\choose 0}}$,   probability that I take colored set with 1 element is ${1\over {n\choose 1}}$  probability that I take colored set with 2 elements is ${1\over {n\choose 2}}$  and so on ...   So $A ={n+1\over 2^n}$. But I have no idea how to attack $B$. U.K visitor visa with very old criminal conviction - do I disclose it? I have been travelling to the U.K for 25 years at least 8-10 times a year,  receiving 5 year visas, never breaking the stay period, with no problem. I've gone through immigration with no problem till my last time in London. I was stopped for eight hours and questioned about a run with the law while I was in college. This was in the US, I was around 20, it was for a credit card use. I received a conditional discharge / probation conviction which was discharged one year later. It was stupid, I was young and in college, more than 28 years ago.  After being questioned about the issue in the US, I was allowed in. They were very polite and professional.  I was also asked if I ever changed my name: I did not change it, but one letter was added in the middle of my first and last names around 20 years ago as our names are translated from Arabic to English and before the digital biometric passports, hand written passports some times varied. It was a common thing at the time.  Now I am applying for my new 5 year visas and I intend to answer truthfully  about previous conviction (previously I answered no because my conviction was spent and I expunged my record.) I want to answer yes and explain it. Is that the right thing to do?  Should I answer yes to the question about having a different name even though it was something as simple as spelling Bryan instead of Brian or Teresa and Theresa -- not really changing it and never thought of it as a change.  I have an impeccable credit rating in the Uk and the last 28 years have never received a moving violation or ever had a run in with the law.  I made one mistake when I was very young but I am  very worried about how to go ahead. I believe honesty is the best approach, is it? How do I add CSS & JavaScript to ? I want to add the following code in my  section of the front page using a Drupal 8 sub theme of Bartik.   Can anybody help how to do it? What is the best way to do it in this new twig version of theme? Where is page.tpl?  &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="stepcarousel.js"&gt;&lt;/script&gt; List files sorted by the number of lines they contain "need to do" vs "need do" Consider:  I need to do this. I need do this.  My English grammar knowledge tells me that &quot;need&quot; doesn't have the same status as the modal verbs &quot;may&quot;, &quot;can&quot;, &quot;should&quot; and what not. Hence the second usage where two verbs appear consecutively is incorrect. But yesterday, my native English speaking friends (Americans) told me that &quot;I need compute this.&quot; is a perfectly grammatical sentence, and one is simply omitting the &quot;to&quot;. How can this be? Is it a colloquial usage but grammatically incorrect, or is it grammatically correct? If it is grammatically correct, is it because &quot;need&quot; is a semi-modal verb? EDIT: in particular, is it okay to use &quot;need compute&quot; in a scientific paper? EDIT2: the exact phrase that raised the question was &quot;The advantage of this representation is that we need only compute sums and products&quot; Is there a git-merge --dry-run option? Why do shadows from the sun join each other when near enough? If $A + A^t = 2I$ then $\det(A) \geq 1$ I'm using python in QGIS. I have a layer of polygons (its a result of some earlier dissolving and has no overlapping polygons but some holes and islands in holes etc). I want to build a new layer which contains one polygon representing a bbox of the first layer with each polygon cut from it.  Essentially I want to "invert" the layer I have so that where the was polygon, now there is not, and where there was not polygon now there is. All inside a bounding box of the original layer.  I can build a bbox easily and I tried to "subtract" the polygon layer from my new bbox polygon layer but the process slows to a stop and then crashes my PC. Here's the algorythm  processing.runalg("qgis.difference","path/to/polygon.shp","path/to/bbox.shp","path/to/result.shp")   I dont care about attributes (obviously). I just need to cut one set of polygons from one larger polygon.  It seems so simple, I wish I could find a simple command or script to acheive this. As stated at the top I'm looking for a solution in python in QGIS. A fellow player is uncooperative with the group and gets GM favoritism. How do I handle this? I actually have two situations but they are interconnected. Our group is currently playing a Dresden game. The GM and one of the players are married. Along with that, he is a new member to the group. I can understand her (the GM) wanting to make him feel welcome but it has gone into the the realm of blatant favoritism. A few examples:   Every idea he has is deemed fantastic, wonderful, awesome and is always successful. Most of the time he doesn't have to roll to see if he succeeds; he just does. After a series of major setbacks to the other player's characters, I joked that her husband was the only one left to mess with. Her answer to that was that she would absolutely not be messing with him in the game. He and his character were safe from that. In the last session, he and another player had to make the same roll using the same skill for the same information. He needed a fair to succeed. The other player needed a great. Not the first time that has happened.    The second part of this has to do with him as well. As I said, he is new to the group. When we were discussing a game to play, it was made clear that it would be cooperative. We would all be working together to a common end. However, he will not- I mean ever- share any information with the rest of the group. No matter how vital or needed that information is to advance the story, he just smiles and says he's got nothing. To try and get around this problem, a group aspect was created. That way if a situation or information that everybody needed to know came up, a fate chip could be played and anyone who wanted to be a part of it could be present. He is totally abusing it. Now, instead of just not telling us anything, he adds give me a fate chip and maybe I'll tell you something. It's like he is trying to beat us at the game and that is not the way it was set up.    So, the question to these two situations is what do I do? How do I handle this in a rational and sensitive way? To complicate things further, the GM is my best friend. He is her husband. I don't want to put her in the middle but I am about ready to quit the game. I am tired of it being his game and everyone else being bit players. Should I talk to her or should I talk to him? If anyone has had experience with this, any advice would be appreciated. Unknown site on Android app When I select the unknown site (i.e. the meta sites) the app crashes.
