Chat flags . This FAQ might be useful to help avoid drama by educating those who handle chat flags.   As a 10k chat user/chat moderator, I see a small blue circle in chat.    What does it mean?  How should I handle it? As a diamond moderator, how does this change?
Chat is an offshoot of the main site, and using it is  during their time here.  Chat is our place for:        Real-time collaboration   Meeting fellow members of the community   Less structured, casual (but still roughly on-topic) conversation      Our chat system exists to serve the main site; users of each site can gather and commune with each other.  When in chat, we expect all users to abide by our  policy, which means that we expect community members to treat each other with respect.    While it is a place where the community can go to interact on a more casual level, chat still needs to be moderated by the community and there are tools in place to help with the moderation. This raises a few questions, that are addressed here:
Make Launchpad Appear on screen with mouse If that's not possible, then a way to trigger the Dock on the screen with mouse without moving my cursor to the bottom of the screen is also an acceptable solution (I know that the launchpad appears on the screen with Dock)  Also i did see the  about this. Why won't Amanita move in and settle down? Should I get Enlightened badge? Today I've got 10 upvotes for an answer. Answer was a first answer in the question. I got an Nice Answer badge for this, but no Enlightened badge.  Shouldn't I get both?  is my answer :) In The Force Awakens, we see Rey pouring some flour-like polystarch rations into water so that the flour amazingly transforms into something that looks like bread. What are these rations? Is there any documentation of the fictional chemistry and biology that makes the starch rations behave as they do? I am looking for help to point me out at a very old novel (likely from the '60s) about two empires at interstellar war. When it comes to starships, one is technologically very advanced, and the other has very low and inefficient technology.  The highly advanced empire has apparently strong chances to win the war, in particular considering a new technology they were developing. I remember the technology to work like this: consider the space as a flat surface, and on this surface, a disk around the spaceship. When the technology was turned on, this disk was stretched out, as made of rubber, so that it produced a cone, with the tip being the spaceship. The spaceship was therefore teleported 10 parsec away (if I remember correctly), but retained all the connections to the original position. If the spaceship moved, the cone moved as well. This allowed to move in position among enemy ships completely unnoticed, by stretching while afar, then moving in the proper position 10 parsecs away, then destretching.  Despite this technology, the empire lost the war because of delays. It's a perfect example of how having a disruptive technology does not guarantee to win against the competitors.  I am trying to find out the author and name of this novel, hopefully with the date of publication and in which journal/magazine. How do I export the code documentation in C# / VisualStudio 2008? I have always made a point of writing nice code comments for classes and methods with the C# xml syntax. I always expected to easily be able to export them later on.  Today I actually have to do so, but am having trouble finding out how. Is there something I'm missing? I want to go Menu->Build->Build Code Documentation, but there is no option to do that, there. How to retrieve the first n characters of a variable in Bash? Stack Overflow has HTTPS in some places! However, this breaks most existing image links. Could those be made protocol-relative, or react to the requesting protocol, or just always use HTTPS?  The same applies to .sponsor-tag-img. I can't seem to get this hat on straight! I carefully positioned my hat to fit my head just right:     But it seems to be shifted to the left a few pixels elsewhere (same in Firefox and Chrome):   Stack Overfow   Skeptics   The top bar is also affected on some sites:   Stack Overfow   Meta SE   InfoSec   However, it is in the correct position in the top bar on some sites somehow:   Skeptics   Bricks   It's not a huge deal of course, it just bothers perfectionists like me. Is the git storage model wasteful? How do I play a YouTube video in the background on my iPad? Bash while read loop breaking early Manga where the protagonist need to solve girl's quests Baking lots of bread - keeping a yeast starter Like many people sheltering-at-home, I'm baking . My yeast supply is running low, and I'm not sure I'll be able to get more on demand. I'd like a simple way to make sure I have yeast on hand for my next batch. Could you all recommend a method for storing a starter culture?  Specifically:   How should I store it (how much? where? I have a fridge ~4C and a wine cooler ~13C)  How often should I feed it? With what? Should I divide the culture when feeding?  How much should I use when baking? Can I treat it like dry active yeast, or does it need more/less time?   For some other context, I'm a novice at making bread (I've made it a few times, and others in my family make it more often). I see lots of advice on sourdough starters, but am interested in something that's a replacement for dry active yeast (unless sourdough starters are actually easier to maintain). I found a  that was similar, but it focused on long-term storage of yeast and the answers did not describe how to use the starter.  Your advice is appreciated. Can't execute .out files, getting permission denied Accessing the index in 'for' loops? Shell script throws a not found error when run from a sh file. But if entered manually the commands work I'm trying to use the following script to generate a sitemap for my website. When I run it as sh thsitemap.sh I get an error like this and creates an empty sitemap.xml file:  thsitemap.sh: 22: thsitemap.sh: [[: not found thsitemap.sh: 42: thsitemap.sh: [[: not found thsitemap.sh: 50: thsitemap.sh: Syntax error: "(" unexpected   But as the same user root when I manually copy and paste these lines on the terminal, it works without any error and the sitemap.xml file have all the urls. What's the problem?

Indirectly access environment variable Given I have in a bash script  ev=USER   How can I get the environment variable value for $USER using ev?  Tried naively doing:  echo ${"$"$ev}   which results in bad substitution.  I'd expect to get back whatever the value of $USER is.
