I want to replicate the shape of this arcade cabinet (in green). I tried to do this by drawing vertices but this leaves me with a jagged edge rather than smooth.   What is the best way to do this? I also tried the bezier curve but then I cant do the straight bits. Maybe there is something I'm missing, any help is greatly appreciated.
I'm new to blender and trying to model the blade of my helicopter and can't figure out how to make an edge curved (for the red tip and selected edge). The object is a plane, with one loop cut. I attempted making a bevel Ctrl B, but nothing happens (A dotted line appears attached to the cursor, moving does nothing, left-clicking does nothing).  also I cant add a curve modifier, just says its disabled. What is the correct way to model this?
The differences between TeX engines I am confused about what TeX and its offspring (LaTeX, pdfTeX/pdfLaTeX, e-TeX, ConTeXt, LuaTeX, etc.) are.  Some, like LaTeX, seem like add ons to TeX (maybe a change to the eyes and mouth, but not stomach). Others, like pdfTeX, seem like changes to the underlying system (i.e., a change to the stomach).  Is there a good reference that explains the differences and the evolution? I have Ubuntu 17.10 with GNOME 3.  What happens: I have (for example) LibreOffice Calc open, with some data columns in it.  I highlight the columns I want to chart, then I select INSERT > CHART.  The chart child window dialog pops up on top of my data, so I want to move it to the side.  When I grab the top bar and move it, the parent (spreadsheet) window minimizes (I think it actually disappears).  Continuing the above example, if I click FINISH on the chart window, I can then see the minimized spreadsheet application, which is the window title bar plus the menu bar just below it.  This seems like really odd behaviour and certainly falls under the category of "not being useful to the user", since the whole idea of moving the child window in the first place was just to be able to better see the spreadsheet!  In other applications, for example the PDF viewer, a slightly different problem occurs.  When I try to move the child window (for example the print dialog) the parent does not minimize but instead follows the child window around.  This is less surprising than having the parent disappear entirely but equally useless in terms of allowing the user to see the information present in the parent window.  Update 2017/11/06  Pomsky's answer below fixes the problem, but leaves me wondering why the window manager is making the decision that all child windows have modal behaviour (or don't), and not the applications themselves; and further, why modal behaviour prevents moving the child screen around when it obscures useful info on the parent screen.  Neither of these seem like good design to me... Why does a candle blow out when we blow on it?

I was improving some of my old posts on Stack&nbsp;Overflow when I ended up encountering this:     You have already edited 5 of your own post today; futher edits are not   allowed until tomorrow   I know this it is not a major deal, but what's the logic underneath to this restriction?

How to disable SMS notification during phone call? I call somebody, or somebody calls me, we are talking. Now, during the call I got SMS and I cannot hear anything because the SMS notification is playing.  So how to disable this notification when call is active? Thank you in advance.

Many LaTeX “hacks” begin with \makeatletter and end with \makeatother. What do these commands do? Winter is Coming It's my understanding that the phrase "Winter is Coming" is the motto of the Stark house, when the story first reaches the wall it's implied that the winter is not a periodic season like it is in our world.  Does the winter refer to a particularly severe season or does a winter only occur every few years? Include sorting of accepted answer on profile I have few things on my mind:   I viewed my profile and I wanted to sort my answers by  "Accepted Answer, Votes" Wanted to know how many answers I've made that is marked as  the accepted answer. Sort by Most liked Question: I'm referring to my question who  have the most numbers of favorites. I wanted to sort the questions I created order by accepted or  unaccepted questions.    1 &amp; 2 seems useful to me but 3 &amp; 4 I don't think are that useful. But who knows, someone in this site might find it useful one day!  My POV: My answer is only sorted by Votes, I also want to see a list of accepted  answers on my profile probably not just to know how many accepted answers  I have but also to know what are the accepted answers that I have. How to find a global minimum for $\frac{1}{2}x^tQx-b^tx$ Is there a suffix for loathing? For instance trichomania is a love of hair, and trichophobia is a fear of hair. But what suffix would denote a loathing of hair?  Edit: Maybe I'm looking at the wrong end of the word, and I should be considering the prefix "miso-". Today I was thinking about composition of functions.  It has nice properties, its always associative, there is an identity, and if we restrict to bijective functions then we have an inverse.  But then I thought about commutativity.  My first intuition was that bijective self maps of a space should commute but then I saw some counter-examples. The symmetric group is only abelian if $n \le 2$ so clearly there need to be more restrictions on functions than bijectivity for them to commute.  The only examples I could think of were boring things like multiplying by a constant or maximal tori of groups like $O(n)$ (maybe less boring).  My question: In a euclidean space, what are (edit) some nice characterizations of sets of functions that commute? What about in a more general space?   Bonus: Is this notion of commutativity important anywhere in analysis? Why are there so few robots in Star Trek? Okay, obviously beyond Data and the Soong-type androids. But seriously, we have more robots in our daily life now than there apparently are on Trek. Is there a canon answer why not? It seems like Star Wars is more on the nose in this regard - it’s unclear why all dirty/dangerous/boring work wouldn’t be done by robots (anthropomorphic or not). This question led to a new package:      I'm trying to make some good-looking numbers in a circle, using the simple command:  \textcircled{1}   However, the circle is misaligned vertically with the number, and look a bit sloppy:    Any suggestions how can I adjust the vertical alignment so that the numbers look more centered w.r.t to the circles? Or, if that's not an option, what other ways to achieve the same results are possible?  I will use those only for numbers, and in very few places, so manual adjustment per glyph is an option.  I'm using pdfLaTeX with Computer Modern, if that matters.
