Why does this Python method re-use this variable?
"Least Astonishment" and the Mutable Default Argument
Do not hide VLQ flag option from users who already flagged and may wish to retract System hides an option to flag Very Low Quality in few cases, namely when post is:        Because of that users who already flagged it when none of above conditions applied miss an option to .  Suggest1 to show this flag option to such users so that they could retract a flag.    1 Frankly I won't mind if this gets  because I doubt that it is important. This is posted mainly to document how system behaves and to provide reference for those who may wonder why they can't retract flag in some cases.

If $a^2+b^2+c^2=1$ then prove the following. I'm searching how to remove the chapter+section number on the theorem numbering with a section counter.  With no section counter it's like:  \newtheorem{thm}{Title} Chapter1 ----Section 1 --------thm 1 --------thm 2 ----Section 2 --------thm 3 --------thm 4 Chapter2 ----Section 1 --------thm 5 --------thm 6 ----Section 2 --------thm 7 --------thm 8   And with the section counter:  \newtheorem{thm}{Title}[section] Chapter 1 ----Section 1 --------thm 1.1.1 --------thm 1.1.2 ----Section 2 --------thm 1.2.1 --------thm 1.2.2 Chapter 2 ----Section 1 --------thm 2.1.1 --------thm 2.1.2 ----Section 2 --------thm 2.2.1 --------thm 2.2.2   And I want numbering my theorems like this:  \newtheorem???????? Chapter 1 ----Section 1 --------thm 1 --------thm 2 ----Section 2 --------thm 1 --------thm 2 Chapter 2 ----Section 1 --------thm 1 --------thm 2 ----Section 2 --------thm 1 --------thm 2   I know it's always a pain to remove such things, thanks for whoever will help me ^^ What happened to /etc/apt/apt.conf? I was browsing through the apt folder to try my proxy settings and I was unable to find the apt.conf file in Ubuntu 11.04. Is there any alternative file for it?  Adding proxy settings to 99-synaptic in apt.conf.d does not help as it gets overwritten everytime I restart the system. A weaker Axiom of Infinity? Numbering in algorithmicx I have simple code:  \documentclass{article}  \usepackage{algorithm}  \usepackage{algpseudocode}  \begin{document}  \begin{algorithm}   \caption{Examples}\label{alg:Examples}   \begin{algorithmic}[1]   \State $X=45$   \State $X=45$   \State $X=45$   \State $X=45$   \State $X=45$    \end{algorithmic} \end{algorithm}          \end{document}     How to put a point after the number of the algorithm? I use chapters in report:  \documentclass[a4paper,12pt]{report}  \usepackage{algorithm}  \usepackage{algpseudocode}  \begin{document}  \chapter{Chapter 1}  \begin{equation} X_2=4 \end{equation}  \begin{algorithm}   \caption{Examples}\label{alg:Examples}   \begin{algorithmic}[1]   \State $X=45$   \State $X=45$   \State $X=45$   \State $X=45$   \State $X=45$    \end{algorithmic} \end{algorithm}  \end{document}     How to change the numbering to take into account the chapters? A problem with my reasoning in a problem about combinations I was given the following problem to solve:     A committee of five students is to be chosen from six boys and five   girls. Find the number of ways in which the committee can be chosen,   if it includes at least one boy.   My method was $\binom{6}{1}\binom{10}{4}= 1260$, using the logic of choosing $1$ boy, then choosing the rest. This was wrong, as the answer was $\binom{11}{5}-\binom{5}{5}= 461$.  The correct answer's logic was committee with no restrictions – committee with no girls.  Why was my method wrong? Please help... What is the possessive of "you guys"? Can the relative pronoun "whose" be used for animals, things and countries? When I was a student of English as a foreign language, more years ago than I care to count, I was taught that the relative pronoun “whose” could only be used for human beings, i.e., when someone possesses something.   My teachers were native speakers from England, then.   Since that time, I’ve seen “whose”, as a relative pronoun, used in several contexts where no human beings are mentioned, e.g. with animals, objects, countries, abstract nouns, etc, in American newspapers and magazines. Unfortunately, I can’t remember any of the sentences and cannot give examples.  What is acceptable in written and spoken English, and what isn’t, concerning the use of “whose” ? User logout on browser / tab close How to modify Drupal user's cookie so the cookie is not available anymore after a predefined time or when the user close his web browser or close all of the websites pages open in tabs ?  After some online searches i found that by setting the cookie lifetime to 0 should create temporary cookies that would be deleted once the browser is closed:  I first tried by modifing some ini_set() values in the settings.php :  ini_set('session.cookie_lifetime',  0); ini_set('session.gc_maxlifetime',   0);   I created a php.ini file located at the drupal site root, containing:  session.cookie_lifetime = 0;   But it does not work on my test site. Any ideas? Use the view from other cameras in the scene as VideoTexture in Cycles I have a scene with monitors that display video from cameras in the same scene (or other scenes, but all of them are linked i.e., same objects in the scene). The cameras shown on the monitors do not view the monitors, so no looping should occur.  I found  that shows how to get the effect in the Game Engine.  I would like to do this in cycles.  Essentially I would like a material input node that corresponds to the output of the composition of a particular scene. The incoming image should honor the render settings of the particular scene and any compositing applied to it.  The Render Layer node does not appear to honor the resolution or compositing settings of the scene it comes from, and is not available to apply as a texture in the material node editor (that I can find).  I understand that this could be done by rendering the animation from the various cameras, then applying that video as textures to the monitors, then rendering the camera of the monitors. That's super tedious if your making changes to the whole scene, and I don't want to do that. What is the Big-O time complexity of the following nested loops: for (int i = 0; i &lt; N; i++) {     for (int j = i + 1; j &lt; N; j++) {         System.out.println(&quot;i = &quot; + i + &quot; j = &quot; + j);     } }  Would it be O(N^2) still? Uncountable ordinals without power set axiom Assume $M$ is a set, in which all axioms of $ZF - P + (V=L)$ hold. Does then $M$ believe that there exists an uncountable ordinal? I mean, why should the class of all countable ordinal numbers be a set? How do I set my level, unlocked weapon equip slots and playthrough mode? Cardinality of a set of closed intervals What is the cardinality of the set S of all closed intervals on the real number line with rational (positive) lengths?  I believe the number of intervals with a specific fixed length but varying start points is |R|, and the number of intervals with a fixed start point but varying lengths is |Q| = |N|. I think the answer to the question would then be |S| = |R x N| = |R|? I'm not quite sure how to prove the last equality though. Would I have to define a bijective function that maps elements of (R, N) to R? How would I approach doing so? Any questions relating to status updates, or asking if anything is going to be patched for these vulnerabilities should be closed as duplicates of this question.    are in the news right now and sound pretty severe. I don't see any security updates from Ubuntu that cover these vulnerabilities.  What is Ubuntu doing about these vulnerabilities, and what should Ubuntu users be doing?  These are CVE-2017-5753, CVE-2017-5715 and CVE-2017-5754.
