Short sci-fi story about Earth blockaded by other human colonies Like the subject: short sci-fi story about Earth blockaded by other human colonies.  The best humans have colonized some stellar systems. But they begin to treat humans of earth like inferiors. A war began, colonies won the war and blockaded the earth, but despite this the earth won. Who is the author? How to safely remove proprietary Intel driver I recently installed the proprietary Intel drivers for my Toshiba Satellite A105 s4284 running Ubuntu 14.10. Nouveau was working just fine, I was just attempting to make it so that I was able to run CS:S (no need for explanation on that.)  Long story short, I went and downloaded the Intel Graphic Drivers for Linux* from . After downloading and installing the .deb, I ran intel-linux-graphics-installer which opened up a window that downloaded &amp; installed the open Intel drivers. I then rebooted, and it's slow. Very slow, especially on 3D effects and when I hit Alt+Tab.  Now, I don't know if the previously installed Nouveau drivers are conflicting with these new Intel drivers (if that's the issue, what should I do about fixing it?) What I do know is that my system isn't behaving right and I want it to (obviously.) If removing the Nouveau drivers isn't the solution, how can I safely remove the just-installed Intel drivers?  Does anyone have any suggestions? Send values from one form to another form Which shell interpreter runs a script with no shebang? Suppose the default shell for my account is zsh but I opened the terminal and fired up bash and executed a script named prac002.sh, which shell interpreter would be used to execute the script, zsh or bash? Consider the following example:  papagolf@Sierra ~/My Files/My Programs/Learning/Shell % sudo cat /etc/passwd | grep papagolf [sudo] password for papagolf:  papagolf:x:1000:1001:Rex,,,:/home/papagolf:/usr/bin/zsh # papagolf's default shell is zsh  papagolf@Sierra ~/My Files/My Programs/Learning/Shell % bash # I fired up bash. (See that '%' prompt in zsh changes to '$' prompt, indicating bash.)  papagolf@Sierra:~/My Files/My Programs/Learning/Shell$ ./prac002.sh  Enter username : Rex Rex # Which interpreter did it just use?   **EDIT : ** Here's the content of the script  papagolf@Sierra ~/My Files/My Programs/Learning/Shell % cat ./prac002.sh  read -p "Enter username : " uname echo $uname Virtualbox has no 64-bit options How can I remove snaps without losing GUI? I want to know how to check how many snaps programs/apps I'm running. Also, how to replace them (if possible) without losing GUI? How do I handle partially correct edits in the Suggested Edits review queue? Contradicting Instructions While going through the suggested edits review queue, one sometimes stumbles upon partially useful edits like . Trying to follow the instructions listed in the descriptions doesn't lead to a conclusive answer. Considering our example:   Approve edits that clearly improve the post ↳ No, not *clearly* Improve Edit when you can make additional improvements to the post ↳ I most definitively can Reject and Edit to replace an ineffective edit with your own substantive changes ↳ It is ineffective in the sense that it made the post worse overall (imho) Reject edits that fail to improve the post or that make it worse ↳ Like the last option: yes Skip if you are not sure and want to go to the next suggested edit ↳ Well, yes. But that is really why I am here, asking this question   Reasoning about the remaining Choices This leaves us with three choices: Improve Edit, Reject and Edit and Reject (the last one slightly modified):  Improve Edit  + Acknowledges that some things in the edit where correct - Learning effect for author might vanish, as the improvement might get overlooked - Can't leave a custom message for edit author (except in comments, which pollutes the thread) - Doesn't trigger the system which &quot;punishes&quot; users who repeatedly have their edits rejected - Rewards the edit author with reputation for a poor edit   Reject and Edit  + Clearly shows the author that there were problems with the edit - Still can't leave a custom message explaining the problems of the original post. - One has to partially redo parts of the edit that have just been rejected, which might feel unjust to the original editor   Reject with a custom note and come back immediately to make a good Edit  + Clearly shows the author that there were problems with the edit + Possibility to leave an explanation as to what was wrong with the edit - One still has to redo parts of the edit that has just been rejected - Seems to be a weird workaround for Reject and Edit   Something else?   Each of the three options come with their distinct advantages/disadvantages making it non trivial to decide which one to pick.  Or does the answer simply depend on the quality of the edit? Like:  Improve Edit for subjectively slightly positive edits Reject and Edit (Or Reject and Edit) for subjectively slightly negative edits How do I change my update server in Ubuntu 18.04? Does a Readied spell immediately use a spell slot? This book came out of the 1970s (early 1980's) at the latest. In it the protagonist, a not so diligent student, gets turned on to computer programming and creates (I think..) a weather program.   Eventually he moves on and years later the program contacts him. It has become an AI and he is its creator.  I forget what the setup is post contact which is not helpful at all.. java.io.Console support in Eclipse IDE I use the Eclipse IDE to develop, compile, and run my Java projects. Today, I'm trying to use the java.io.Console class to manage output and, more importantly, user input.  The problem is that System.console() returns null when an application is run "through" Eclipse. Eclipse run the program on a background process, rather than a top-level process with the console window we're familiar with.  Is there a way to force Eclipse to run the program as a top level process, or at least create a Console that the JVM will recognize? Otherwise, I'm forced to jar the project up and run on a command-line environment external to Eclipse. I have this alias set in my system /etc/bashrc file:  alias root="sudo !!"   The intention of this being to run the last used command using sudo of course. When used, it of course appears to substitute the last command in history to the bashrc file upon shell initialization, and not the actual command that you would get if you were to run sudo !! in an interactive shell. I've also tried alias root="sudo fc -s" to no avail.  I realize this is probably something to do with how the BASH does command substitutions, but can someone explain why this is, and provide a usable substitute?  I'm running BASH version 3.2.51(1)-release (x86_64-apple-darwin13). Are all algebraic integers with absolute value 1 roots of unity? The internal storage on my phone is almost full. The storage screen tells me    2.77GB / 2.91 GB taken Apps 0.89GB Other 1.89 GB Available 138MB   What is this "other" and how can I clean it up? I already followed the steps of "make more space", it barely makes a difference.   Phone Storage then tells me 43.00MB / 1.09GB is taken.  And on the SD card I have 1.86GB / 14.72GB taken.  I have plenty of storage in various places yet when I try to install apps I'm unable to do so cause of "insufficient storage". How can I fix this? Minimum bounty on a question is now 100 rep? Does reviewing queues have any gains for me as a Stack Overflow user? Limit point versus limit and implications for convergence I understand that similar questions to this have been asked  and  but I believe my question is different because with regards to (1) I am not asking about the set $X$ that contains the points of my sequence and with regard to (2) because I have the distinct definitions of limit and limit point in mind. That said:  My Question: My textbook, Fundamental Ideas of Analysis by Michael Reed, defines a limit point as:     Definition: Let $(a_n)$ be a sequence of real numbers. A number $d$ is called a limit point if, given $\epsilon &gt; 0$ and an integer $N$, there exists $\color{red}{\mathrm{ an }} \ n \ge N$ so that $|a_n - d| \le \epsilon$.    The definition of a limit is as follows:     Definition: We say that a sequence $(a_n)$ converges to a limit $a$ if, for every $\epsilon \ge 0$, there is an integer $N(\epsilon)$ so that $|a_n - a| \le \epsilon \color{red}{\text{  for all  }} n \ge N$.    From these definitions, and given this question:     If a sequence converges it has exactly one limit point. Is the converse true? If not, provide a counterexample   Can I conclude that the converse is indeed true simply by appealing to the definitions, or do I need a tighter proof. And if I do, I'm a little stuck on how to refine this proof. If $X$ and $Y$ are sets, their cartesian product $X\times Y$ is a set. In ZFC set theory, every element object is a set. We know or feel that if $X$ and $Y$ are sets, their cartesian product $X\times Y$ is a set.  My question is: Why if $X$ and $Y$ are sets, their cartesian product $X\times Y$ is a set? What to do with meta questions referring to currently non-existing features? I sometimes come across such questions like that:    The "Not a real question" close reason doesn't exist for long time. It doesn't make sense to answer, comment, or even up/downvote (since there's nothing more to vote for/against it).   Shouldn't such questions be locked as historical ones? Should I flag them for moderator attention or just ignore them? I'm making an python script which create a lot of object and this could take a lot of time. My question is how to show to the user of my script, the "progression" of the script? For now I print an progress bar in the system console.  But you have to open the system console befor and (apparently) the system console only work with Windows.  Is there an other way to show the progression of my script with python like control the mouse percentage icon (the little icon that replace the mouse while baking) or another idea?
