What does echelon mean? When you solve a system of linear equations, you write down the augmented matrix and reduce this to reduced row echelon form. What is the meaning of the word echelon? Missing return statement in a non-void method compiles What is a "double date"? I usually render my animation into image sequence format, It usually takes a lot of time, so I turn off my monitor and come back later to check the rendered result then find that blender crashed before rendering all the frames.  Since rendering can be done from the command prompt I thought about writing a script (running in my OS) to automatically restart rendering from the last successful rendered frame until all frames are finished*.  But I believe this problem is facing a lot of people out there, is there a way to deal with it? instead of reinventing the wheel?     for example if the total render time is 8 hours I don't want come back to check my computer every 20 minutes (some times this is not available I'm asleep or away from my PC) The result of ls * , ls ** and ls *** I know using the command ls will list all the directories. But what does the ls * command do ? I used it and it just lists the directories. Does the star in front of ls mean how deep it will list the directories? Why was Severus Snape placed in Slytherin? How do you get \mathbb{1} to work (characteristic function of a set)? I am trying to get the digit one printed the \mathbb{} font in math mode, however the command  \mathbb{1}   outputs some rubbish. I certainly saw the character I am after in some pdf's generated from latex, hence my question: how do you get it to work? Cardinality and infinite sets: naturals, integers, rationals, bijections Suppose f is a twice differentiable function with $f(0)=0$ and $f(1)=1$, $f'(0)=f'(1)=0$. Then show that $|f''(x)| > 4$ for some $x$ in $(0,1)$ What's better to use in PHP for appending an array member,  $array[] = $value;   or  array_push($array, $value);   ?  Though the manual says you're better off to avoid a function call, I've also read $array[] is much slower than array_push(). What are some clarifications or benchmarks? Qualcomm Atheros AR9462 with Ubuntu 18.10 I can't enable the Wifi (nothing happens when press enable button) and in Wifi settings it says:     "No Wi-Fi Adapter Found"   I have tried several things from other questions/answers here but nothing worked.

Patch 2.0.1 introduced a lot of significant changes to the loot system in the game. One of the significant ones was the revamp to the , which now has a new effect:      Summon a treasure goblin who picks up normal-quality items for you. After picking up 12–16 items, he drops a rare item with a chance for a legendary.    What is the cooldown on the goblin item drop? Does the effect stack if you have one on your character and another on your follower (i.e. two goblins)? Is the drop chance for the rare/legendary affected by increased Magic Find? If so, approximately how much? Is there a cap on them max item level of the dropped item? (While &lt; lvl 60, at lvl 60, and when the level cap is raised in the expansion.) Does the item counter reset when you leave the game, change acts, or die? Correlation with a constant How do I recursively create a folder inside another non-existent folder? I want to create this folder: $HOME/a/b/c/d while $HOME/a has not yet been created! Is it possible with one line in Terminal? Correct user names when tracking /etc/ in git repository and committing as root How scientists can be confident that human embryo tail is really a tail? From :     Human embryos have a tail that measures about one-sixth of the size of the embryo itself. As the embryo develops into a fetus, the tail is absorbed by the growing body.   How are we sure that it is a real tail and is not a superficial resemblance of something else?  I ask this because some creationist guy challenged me in this regard. How does "Reputation" work? How to create Unity indicators? I'm interested in Unity indicators and wonder if there is any tutorial on how to program them. I can use the sources of the existing ones as last resort, but I'd prefer a more friendly approach because my programming skills are quite limited. Can a JavaScript object have a prototype chain, but also be a function? function a () {     return "foo"; }  a.b = function () {     return "bar"; }  function c () { }; c.prototype = a;  var d = new c(); d.b(); // returns "bar" d(); // throws exception, d is not a function   Is there some way for d to be a function, and yet still inherit properties from a? Infinite series for $e$... How do you prove that $e=\sum_{n=0}^{\infty}\frac{1}{n!}$? Here I am assuming $e:=\lim_{n\to\infty}(1+\frac{1}{n})^n$. Do you have any good PDF file or booklet available online on this? I do not like how my analysis text handles this...
