Hyperspace travel is a norm in Star Wars universe. Even small ships have that capability and without this capability galactic-scale economy isn't possible.  My educated estimates say that at any point of time at least billions of ships are in hyperspace across the galaxy. Now, talk about economic hubs like Coruscant during Clone Wars Era. The number of ships arriving here should be enormous. Millions in an hour? If one person small ship can have warping capability, then the number can exceed even billions in a peak hour. You can go shopping on a neighbor planet five times a day or you can live on a cheap planet even if you have a job on Coruscant (there are public transport cabs featured in Rebels TV show in case you aren't rich enough to have own ship).  Now, the famous quote:     "Traveling through hyperspace ain't like dusting crops, boy! Without precise calculations we could fly right through a star or bounce too close to a supernova, and that'd end your trip real quick, wouldn't it?"   That's fine. Calculations prevent you from hitting a star, supernova or planet which are already on map, but how does a ship avoid hitting another ship? Provided that number of ships arriving near a planet is that much high, the probability of two ships jumping to the same co-ordinate can't be zero. In fact, the probability should be very very high.  Is there a central body which controls the traffic by coordinating the hyperspace calculations of different ships? This seems unlikely because everyone seems to go anywhere they want while maintaining the destination privacy (there are countless examples). Or, is there really a traffic control body and those who travel privately actually gamble? Is there any other protocol if not traffic control body?  Has the canon ever addressed it? What about Legends? Proof of "Dual normed vector space is complete" I just saw Death in Paradise Season 5 Episode 3, which features a photographer using a DSLR to shoot a fashion runway performance.  He had a flash that was a ring around the lens.   I thought that was for macro shots only, where the extreme close-up has trouble with normal flash placement.  For normal photos you want the flash far from the lens, like on a boom on a separate handle framing the camera.  I've seen some recent trendiness in having ring-shaped catch lights, but I supposed those would be positioned in the normal manner: off-angle from the lens.  I suppose if an on-camera had any effect at all it would be for some subtle fill flash.  Is this a realistic thing to see from a pro? Or is it just a cool-looking prop that doesn't really fit the situation? I think it's something like  this: (Fedora14/bash)  #!/bin/bash  for i in {0..10..1}; do echo -e "$i"'\c' echo -e "\n\r" sleep 1 done   But it doesn't work. Purpose: like this, but without the "clear":   #!/bin/bash  for i in {0..10..1}; do echo -e "$i" sleep 1 clear done   So a counting script that doesn't deletes the whole screen to output +1 number, instead it only deletes the line, where the counting is, so that there could be ex.: a beatifull "progress bar".. I have gcc 7.3.0 on Ubuntu 18.04. But I am working on a project where I need gcc less than version 6. When I tried to install gcc 5.4 using sudo apt install gcc-5.4, I got this error:  Reading package lists... Done Building dependency tree        Reading state information... Done E: Unable to locate package gcc-5.4 E: Couldn't find any package by glob 'gcc-5.4' E: Couldn't find any package by regex 'gcc-5.4'     What is the appropriate way to install gcc 5.4? Best way to deal with questions answered by the OP in the question instead of in an answer I saw this question:   I don't know what the best option is for dealing with such a question, because I've seen questions like this several times already.  So, what should we do with questions that are:   poorly asked finally answered by the OP as an update to the question itself, not as an answer. How to check whether a JavaScript variable defined in cross-browser way?  I ran into this problem when writing some JavaScript utilizing FireBug logging. I wrote some code like below:  function profileRun(f) {     // f: functions to be profiled     console.profile(f.constructor);     f();     console.profileEnd(f.constructor); }   It works fine in FireFox/FireBug, but it reports error in IE8 RC1. So, I'd like to do some checking whether console variable exists in the execution environment.  Below code works fine in FireFox, but not in IE8 RC1.   function profileRun(f) {     if (console != undefined) {         console.profile(f.constructor);     }      f();      if (console != undefined) {         console.profileEnd(f.constructor);     } }   However, if I do it this way. It works in IE8 RC1. Why?   function profileRun(f) {     if (window.console != undefined) {         console.profile(f.constructor);     }      f();      if (window.console != undefined) {         console.profileEnd(f.constructor);     } }   Is there any cross-browser way to check it? Do I need a bus/train/plane ticket out of Thailand in order to get a Visa-on-Arrival? When did the word "so" begin to be used to start a sentence? In the last few years, I've noticed a growing usage of the word "so" to begin a sentence, especially in the context of higher education.  For example:   Interviewer: "What is the nature of your research"  Researcher: "So, what we wanted to find out is..."  It seems to be a replacement the word "well", or, more informally, "ok".  Has this usage of the word been around for a long time and I'm just now noticing it?  Do you think that is a valid use of the word? Show that there are $ a,b \geq 0 $ so that $ |f(x)| \leq ax+b, \forall x \geq 0.$ I have the following exercise: $$f:[0, +\infty) \rightarrow \mathbb{R} \text{ uniformly continuous  } .$$ $$\text{Show that there are } a,b \geq 0 \text{ so that } |f(x)| \leq ax+b, \forall x \geq 0.$$ $$$$ $f:[0, +\infty) \rightarrow \mathbb{R} \text{ uniformly continuous  } :$ $\forall \epsilon &gt;0 \exists \delta &gt;0 \text{ such that } \forall x,y \in [0, + \infty) \text{ with } |x-y|&lt; \delta \Rightarrow |f(x)-f(y)|&lt;\epsilon$ $$$$ How can I continue?? How to convert a column number (e.g. 127) into an Excel column (e.g. AA) Why do this() and super() have to be the first statement in a constructor? $A=\begin{pmatrix}0&amp;0&amp;1\\ 0&amp;1&amp;0\\ 1&amp;0&amp;0\end{pmatrix}$  How do I show that there are no solutions for $X^2=A$ in $M_3(R)$?  I tried $X^2=\begin{pmatrix}a_{11}&amp;a_{12}&amp;a_{13}\\ a_{21}&amp;a_{22}&amp;a_{23}\\ a_{31}&amp;a_{32}&amp;a_{33}\end{pmatrix}^2=A$, but I couldn't seem to find anything that shows there are no solutions. How should I approach this? Inequality $\frac1a + \frac1b + \frac1c \leq \frac{a^8+b^8+c^8}{a^3b^3c^3}$ Let $a,b,c$ be positive reals . Prove that $\displaystyle \frac1a + \frac1b + \frac1c \leq \frac{a^8+b^8+c^8}{a^3b^3c^3}$  I found this one in a book, no hints mentioned, but marked as very hard. I can't make any progress... How could I select one vertex from my mesh if I know ID of that vertex? I enabled bpy.app.debug = True and I can see all IDs but cant find a specific one. I've noticed that if I downvote an answer, the record of the downvote is visible to me in my profile.  But when I view my profile from another browser that's not logged into Stack Overflow, I've noticed that I don't see the record of the downvote.  So I was wondering if the downvote record is visible only to me?  If so, is this done to protect downvoters from retaliation? "Hail Mary", "Glory Be" in the plural Possible Duplicate:          In the rosary, a Catholic sacramental composed of prayer beads, there is a short prayer concluding each decade called "Glory Be" ("Glory be to the Father, Son and Holy Spirit...").  Would the plural be Glory Bes or Glory Be's?  Likewise, do you say 10 Hail Marys? What is the meaning of the axes in t-SNE? I'm currently trying to wrap my head around the  math. Unfortunately, there is still one question I can't answer satisfactorily: What is the actual meaning of the axes in a t-SNE graph? If I were to give a presentation on this topic or include it in any publication: How would I label the axes appropriately?  P.S: I read  Reddit question but the answers given there (such as "it depends on interpretation and domain knowledge"), don't really help me to understand this. How to normalize data between -1 and 1? I have seen the min-max normalization formula but that normalizes values between 0 and 1. How would I normalize my data between -1 and 1? I have both negative and positive values in my data matrix. How can you change the href for a hyperlink using jQuery?
