Can't figure out how to properly setup SPF record

I have a Django web app and I use Django's email backend to send out emails. I can't figure out why emails are ending up in spam folder. My domain host is GoDaddy so I added a TXT record  *.example.com TXT v=spf1 a ~all   This is the header of emails, sometimes I get different sending server IPs.  Return-Path: contact@example.com Received: from www.example.com (li235-14.members.linode.com. [xxx.xxx.xxx.xx])     by mx.google.com with ESMTP id u1si13870322qaf.95.2014.08.15.14.44.10 Received-SPF: none (google.com: contact@example.com does not designate permitted sender hosts) client-ip=xxx.xxx.xxx.xx; Authentication-Results: mx.google.com;    spf=neutral (google.com: contact@example.com does not designate permitted sender hosts) smtp.mail=contact@example.com; Received: from localhost (localhost [127.0.0.1])    by www.example.com (Postfix) with ESMTP id 23336B8E1   Should I add Linode's IPs as wildcards?  Any suggestions appreciated.


How to solve $x^x=a$ and related equations?

How can I solve the equation for $x$ when $x^x=2$ or any other constant? And is solving $x^{x^x}=a$ or $x^{x^{x^x}}=a$ or equations such as these even possible? What are these equations even called?   And what about the following? $$x^{(x-1)^{(x-2)^{\dots^{3^{2^{1}}}}}}=k$$  or $$a\;x@n+b\;x@(n-1)+c\;x@(n-2)+\cdots=0$$  where "$@$" is an operator I made to indicate the number of exponents, as $x@3:=x^{x^x}$.  I have already tried taking logarithms, using taylor series, etc.


How to read data from local json file in javascript?

i am new to javascript and am not sure how to read data from json file using javascript. i have data like below in my json file located in path api/data.json {     "description": " description",     "data": [         {             "id": "1",             "title": "first_data_title",             "items": [                 {                     "id": 1,                     "title": "item1_title"                 },                 {                     "id": 2,                     "title": "item2_title",                 },                 {                     "id": 3,                     "title": "item3_title",                 }             ]         },         {             "id": "2",             "title": "second_data_title",             "items": [                 {                     "id": 4,                     "title": "item4_title"                 }                 {                     "id": 5,                     "title": "item5_title"                 }             ]         },         {             "id": "3",             "title": "third_data_title",             "items": [                 {                     "id": 6,                     "title": "item6_title",                 },             ]         }     ] }  as seen from above data is an array of objects where each data has array of items. now i want to display each data with its title and its items title in a list. meaning like below, [![enter image description here][1]][1]  on loading the application my code is like below, index.html <!DOCTYPE html>               <meta charset="UTF-8">         <meta name="viewport" content="width=device-width, initial-scale=1.0">         <meta http-equiv="X-UA-Compatible" content="ie=edge">         <link rel="stylesheet" href="src/styles.css">

EDIT: tried like below i am trying something like this function onload() {     console.log('onload');     fetch('api/data.json')         .then(response => {             if (!response.ok) {                 throw new Error("HTTP error " + response.status);             }             return response.json();         })         .then(json => {             const data = json;             console.log(data);         })      }  this gives unexpected token error. i think the problem is using .then so i tried using async method async function onload() {     const data = await fetch('api/data.json');     console.log('data', data); }  this gives the regeneratorRuntime not defined error. i have tried to do like below functio onload() {   fetch('api/data.json)    .then((response) => {         console.log('res', response.json);        return response.json();     })     }  and this logs error and log statement in console like below  below is how the files are structured and i am trying to just read json data from data.json file located in api folder.


Is the ban on applying for a US visa after marriage fraud a lifetime ban or 10 years?

A Jamaican committed marriage fraud about 30 years ago by marrying a US citizen in a marriage where the groom was paid a certain amount of money to marry her. The groom got in legal trouble for an unrelated matter, and the marriage fraud was discovered and the family friend was deported back to Jamaica. She no longer has any paperwork involved with the deportation and she can’t remember any of the details. I do not know if she simply agreed to return to Jamica when the fraud was discovered, or if she made any attempts to mount any type of legal defense in the case. I do know that she was cooperative with the immigration authorities and that they did not have to come looking for her. She would like to come the USA for a two-week visit. The main purpose of the visit is for her to visit a friend (US citizen) who is terminally ill.  I have been looking at 8 U.S.C. 1182 and from my reading of it, it would seem that she would not be admissible to the US because of the previous immigration fraud. My understanding is based on the section that says:     In general.-Any alien who, by fraud or willfully misrepresenting a material fact, seeks to procure (or has sought to procure or has procured) a visa, other documentation, or admission into the United States or other benefit provided under this Act is inadmissible.   What’s not clear to me is if this means that she would be inadmissible permanently or if this would be subject to the 10 year limit.  Can anyone help provide some clarity on this?  If the ban is not permanent are there any tips to being able to increase her chances of being able to get a visa.  She intends to honestly answer all questions during her application process for a visa.


Number of Forests on Vertex set with two Connected Components

So the question I am trying to solve is:  Show that the number of (non-equal) forests on the vertex set $V = \lbrace1,2,...,n\rbrace$ that contain exactly two connected components is given by the formula   So I am a bit lost on where to start with this. I was thinking of maybe looking at how many with only one connected components there would be and trying to generalize an equation to get how many would have two. Any help here would be appreciated.


Can I add another suitcase in one of my connecting flights?

I am flying from A to B, with a connecting flight through London Heathrow (i.e. A -> LHR -> B). Both flights are with the same company/conglomerate, and so my bags will still be in transit (and not with me).   I have a 10 hours wait in LHR and want to go downtown and do some substantial shopping (including alcohol). I plan to buy another suitcase, fill it with these shopping, and then dropping at the bag drop, so I can have it at my final destination.   Is it possible to do this? Can I add another suitcase in one of my flight connections?


How to share a question on different related SE sites?

My question is that I asked a question on stackoverflow.com and  I want to share my question to all other technical stackoverflow linked sites like ,  etc.  I want to share my question on only selected sites related to stackoverflow. I don't want to post duplicates, I just want to make my question visible for the users on the related site, that may not necessarily be the members of the both sites, but may be competent to answer.  Is there any option in StackExchange network to perform this operation?  Can any one suggest me how I can do this?


Why NOT to use wildcard imports like java.util.*?

I am a student, and a couple of the books I have been reading (Java for Dummies, for one) has said using the wildcard import statement is bad programming practice and encourage the reader to avoid using it. Whereas, in class, we are encouraged to use it. Can somebody please explain why it is poor programming practice?   If so, what adverse affects does it have on the program performance? For example, slow it down.


when I was catching up with Evans PDE and I realise I do not have a good understanding about limsup and liminf.  I found the following exercise in a real analysis book that motivates the definition of limsup.But I have no idea how to answer.   Let $(x_n)$ be a bounded sequence. For each $k\in\mathbb{N}$, let   $$y_k=\sup_{n\ge k} x_n=\sup\{x_k,x_{k+1},x_{k+2},\cdots\}.$$   Show that the sequence $(y_k)$ is decreasing and bounded below.  Conclude that $(y_k)$ converges.   [Part 1) was solved in previous posts, but I have not found an answer for part 2)]


How much higher is the legendary drop rate in the Torment difficulties?

The ingame explanation of the different difficulty levels states that the Torment difficulties increase the drop rate of legendaries. But they don't state exactly how large this increase is.  I've farmed a bit on Normal difficulty and found some nice stuff, but I'm also roughly able to farm at Torment I difficulty. I'm wondering if the large decrease in speed compared to Normal is worth it for me, but to judge that I need to know a bit better how large the increase in legendary drop rate is.


Orcs appear to be sentient. Orcs are (possibly) derived from elves who do possess fëa. So do they possess "a soul"? and if so, what happens to it when they die? do they get the gift of men?


I vs myself when talking about 3 people (including me)

Is there a way to get security updates for wheezy after EOL

I know the best solution would be to upgrade the server after Debian wheezy has reached End Of LIfe in May 2018, but is there a way to continue running an old wheezy instance and get some minimal updates still?  Maybe some external apt-sources, that still are getting maintained somewhere?


Special tagging for questions from students or beginners?

It seems to me, there are two broad categories of questions: (1) from people who use a programming language at their work place, and (2) from people who just started to learn using it. Almost everyone in the community seems to understand, based on the quality of the question, to answer the latter by initiating some thought and not just giving the solution.  I think, SO can do more to facilitate this. I am thinking about a special tag "beginner". Ideally, the actual accepted answer should not be revealed for questions tagged with such tags until clicked.  Do you think this would make sense? Maybe some other ideas?


Regex: Remove duplicate html tags in multiple files

I have this 4 tags, each is repeated once. Of course, I have 800 html files.

Difference between events and delegates and its respective applications

I don't see advantages of using events over delegates, other than being syntactical sugar. Perhaps I am misunderstanding, but it seems that event is just a placeholder for delegate.  Would you explain to me the differences and when to use which?  What are the advantages and disadvantages? Our code is heavily rooted with events, and I want to get to the bottom of it.  When would you use delegates over events and vice versa? Please state your real world experience with both, say in the production code.


Clicking on a notification on Android app opens an empty feed

When I receive a message on an SE post, I get a notification like this:    If I double tap this notification, the SE application opens, but my feed is empty approximately half the time. It looks like this:    If I refresh the feed (slide from the top), the feed does refresh and shows the new notification.   The notification, above, leads to  comment.  I haven't figured out the pattern yet, but this occurs roughly half the time I open a notification. It's occurred for chat messages, comments and answers - but not consistently. I have received notifications for the same post (for example, the two comments after the one linked above) that do not show an empty feed. But, a chat message barely 10 minutes later will show the empty feed again.  I am utilizing the beta app - version 1.0.72 on Android 5.0.1.


Maven , How to let dependency of local system jar be included into the output jar?

I have a class ClassA in package packageA and ClassA import ClassB in packageB.(in fact ClassA import a lot of java file)  Then the directory is ：  root     pom.xml     src           packageA                   classA                   pom.xml          packageB                   classB   My goal is to generate a jar include classA and classB by only telling maven that I input classA.  the pom.xml in the packageA directory is like  <dependencies>     <dependency>         <scope>system</scope>         <systemPath>D:\path\to\my\local.jar</systemPath>         <groupId>com.abc</groupId>         <artifactId>abc</artifactId>         <version>0.0.1-SNAPSHOT</version>     </dependency>     <dependency>         <!--other dependency in maven repo-->     </dependency> </dependencies> <build>     <plugins>         <plugin>             <artifactId>maven-assembly-plugin</artifactId>             <configuration>                 <archive>                     <manifest>                         <mainClass>fully.qualified.MainClass</mainClass>                     </manifest>                 </archive>                 <descriptorRefs>                     <descriptorRef>jar-with-dependencies</descriptorRef>                 </descriptorRefs>             </configuration>             <executions>                 <execution>                     <id>make-assembly</id>                      <phase>package</phase>                      <goals>                         <goal>single</goal>                     </goals>                 </execution>             </executions>         </plugin>     </plugins>     <sourceDirectory>.</sourceDirectory> <!--if I don't add this line ,the output jar will not include anything of my own project--> </build>   You know, if I don't add <sourceDirectory>.</sourceDirectory> it will not build any thing.But if I add<sourceDirectory>.</sourceDirectory>,the output jar only contains the <sourceDirectory>'s path's classes and the dependencies of maven repo , without my jar of local system path  (In fact the local jar of my own is to support the <sourceDirectory>'s path's classes' build .Also in fact the local jar contains the classB)  Why my own jar's related classes have not been added in the output jar?

Although grade = 4.699991 instead of 4.7. Everything I tried I can't get the 4.7 and always I get 4.66691.Any suggestion?  Netbeans, MINGW-64,Windows 10 prof


How do I get Cudy AC1200 usb wireless wifi adapter running in Kubuntu 20.04*?

I need help with getting my Cudy AC1200 5dBi wireless adapter running in Kubuntu 20.04. I carefully followed the driver install instructions from the manufacturer (driver install instructions link: )(driver install link: ), but I don't know what to do after this point? For example, how can I verify it is running? How can I view and/or change settings? After I installed the drivers and plugged in the antenna, I opened up terminal and ran the lsusb command (I found this advice on AskUbuntu) to see if the adapter was recognized. It looks like it is recognized. It is noted as "Bus 003 Device 011: ID 0bda:b812 Realtek Semiconductor Corp. 802.11ac NIC". I unplugged and plugged it in several times and ran the lsusb command to confirm. It appears it is recognized. I am running Kubuntu 20.04* on a 2012 Mac Mini desktop computer. Kubuntu is up-to-date. What do I do next after installing the driver? Although the device is recognized according to the lsusb command, I am not seeing any signal benefits. It seems the device or driver is actually not running. I looked in System Settings to see if there was something that mentioned the device but I could not find anything. Please assist.


How do I fix "The expression of type List needs unchecked conversion...'?

In the Java snippet:  SyndFeedInput fr = new SyndFeedInput(); SyndFeed sf = fr.build(new XmlReader(myInputStream)); List<SyndEntry> entries = sf.getEntries();   the last line generates the warning   "The expression of type List needs unchecked conversion to conform to List<SyndEntry>"  What's an appropriate way to fix this?


Is $\cot(z)-\frac1z$ bounded on a given circle?

I am getting stuck with the problem given from the book Schaum's outlines p.240 Q.110  Given $f(z)=\cot(z)-\frac1z$ where $z$ lies on a circle of radius $R=(N+\frac12)\pi$ and centered at the origin. Prove that $|f(z)|\le M$ where $M$ is independent of $N$.


Prove that at most $2k+1$ independent sets form the set of vertices of a graph, where $k$ is the maximum degree.

I have a graph $G(V,E)$ where each vertex has degree at most $k$. How can I prove that I need at most $2k + 1$ disjoint sets of vertices in which there is no connection between two vertices from the same set to create the set of vertices $V$.


How to find 100 consecutive composite numbers? After many attempts I arrived at the conclusion that to find $m$ consecutive composite numbers we can use this $n!+2, n! +3, ..., n! + n$ where $n! + 2$ is divisible by $2$, $n! + 3$ is divisible by $3$ and so on... and where $m$ = $n-1$ Thus $n!+2, n! +3, ..., n! + n$ tells that there are $(n-1)$ consecutive numbers. However, there seems to be some gaps or incompetence. For example: $4!+2, 4! +3, 4! +4$ $→$ $26, 27, 28$. Although it's right there are for sure smaller numbers such as $8, 9, 10$ and $14, 15 ,16.$ Is there another method for solving such a problem mathematically? Is it a correct method or have I misunderstood it?

Allow to search by user id when user is deleted

Specifying the user:<id> option to the  allows you to search for posts written by specified user. That also includes the , which are considered community owned (almost everyone could modify them). But I was surprised that searching by user doesn't work for deleted users, despite of the fact that user id is still visible on the user card:        Could the searching for posts made by currently deleted user be possible? Is there a reason to don't allow it?   One possible usecase is when the user with a lot of useful posts decides to delete your account, and you will be able to search for they posts though.


When should "into" be used rather than "in to," and vice versa?

"Into" (one word) and "in to" (two words) are frequently confused.  In what situations should the former be used?  The latter?


When do I answer negative questions (e.g. "Aren't you...?") with "yes" or "no"?

I want to know how to answer negative questions. For example, take the following example:  Q: "Aren't you supposed to be there at 7? You don't have time." A: "No, I can make it on time."  Someone told me that my response above is wrong, and that I should answer with:  A: "Yes, (I am.) I can make it on time."  or  A: "No, I'm not supposed to be there at 7."  Can you explain for me which one sounds normal to native English speakers?

How to get rid of CAPTCHA prompted by Google (while searching)?

I am a programmer and I Google a lot.  The problem.  The thing is that it seems that Google finds my search requests fishy (often related to security and compile errors, something casual users won't search for) and asks me to enter CAPTCHAs from time to time.  It all started something about a year ago - I've found myself entering CAPTCHAs a couple of times a week - not really pleasant, but something one can live with. Sometime about half a year ago the situation got worse - Google asked me to enter CAPTCHAs up to five times a day (!), but after some time it eased a bit and lately I've been entering CAPTCHAs about once a week. Last week Google started to ask me double CAPTCHAs (asks one and another immediately. First CAPTCHA was entered 100% correct - I triple checked it).  It is true that I sometimes search really weird stuff but CAPTCHAs keep being asked even for casual queries. Also it happens when I Google on different OSes (Windows/Ubuntu) and in different browsers (Firefox/Chrome), so I suspect that this is something that is relevant to my Google profile.  What I tried.   Dug through Google account preferences - found nothing useful. Saw some articles and tutorials on the internet (), but all that I stumbled upon was outdated and didn't help me to solve my problem.     So, in the end, what can I do to confirm that I am a human once and for all, or at least reduce amount of CAPTCHAs that I have to enter while googling?

Properties of the quotient ring $\mathbb{Z}_6[x]/\langle2x+4\rangle$

Consider the ring  $R = \mathbb{Z}_6[x]/\langle2x+4\rangle$ . Which of the following are true?   $R$ has infinitely many elements. $R$ is a field. $5$ is a unit in $R$. $4$ is a unit in $R$.   I know that $R = \mathbb{Z}_6[x]/\langle2x+4\rangle = \{f(x)+\langle2x+4\rangle\mid f(x)\in{\mathbb{Z}_6[x]}\}$ and that $(2x+4) + \langle2x+4\rangle = 0+ \langle2x+4\rangle$, which implies $x=-2$ in $R$.  also $\mathbb{Z}_6$ is not field and $(2x+4) = 2(x+2)$ is reducible in $\mathbb{Z}_6[x]$ (also $2x+4$ has a zero in $\mathbb{Z}_6$).  I know that if I will prove that R is not ID then it is not field but I am not getting any direction  Please give me some direction.

How Do I Subdivide A Bezier Curve using Python?

I'm using Python to create a Bezier curve programmatically. bpy.ops.curve.primitive_bezier_curve_add() bpy.ops.curve.subdivide(number_cuts=4)  The code above works fine in the console, but not in my script. I get the error message: bpy.ops.curve.subdivide.poll() failed, context is incorrect I've tried both primitive_bezier_curve_add(), and ...add(enter_editmode=True). Same result. Using Blender 2.83.2 NOTE: I am able to use this as a workaround: bpy.context.scene.objects["BezierCurve"].data.splines[0].bezier_points.add(count = 4)

Accidentally moved framework file to trash and now finder continuously fails

I have the exact same problem as this person: , except that I removed; Social.framework, Weathkit.framework and ContactsAgent.framework.   Finder reptitively fails saying it can't load the libraries. I can view the files in my .Trash directory via Terminal, however I've unsuccessfully attempted to move them back multiple times by executing mv .Trash/Social.framework.  Honestly, I really dont care about any of those apps but I want Finder to work.  If someone would please upload a zip file of those frameworks, so that I could do the same thing as Sayan and replace, that would be much appreciated.

Delete C:/ Windows partition and install Ubuntu?

I have 3 disk partions in my Windows 7 laptop. I would like to replace Windows with Ubuntu. But I want to save my data on other 2 partions. Is it possible for me to format C:/ Windows default partition and install Ubuntu on it? For so long I wanted to do this. Appreciate your help.


Given $(a_n)$ consider $(s_n)$ given by $s_n = \frac{1}{n}(a_1+a_2+\cdots+a_n)$ for $n \in \Bbb N$. Show that $a_n \rightarrow a$ implies $s_n \rightarrow s$.   Further find a divergent sequence $(a_n)$ for which $s_n$ converges.    I've been told to use the Stolz-Cesàro theorem to prove this. However, I'm new to analysis so I couldn't figure out the proof. Is there a more basic way?

Filling the arrow tip and not the path using two different colors

I have a small problem with some arrows but I can't seem to find a solution. Please note that this question is different from , since there the OP meant to make the whole arrow of one color.   If I wanted the arrow tip to be black and the arrow path to be colored, I'd simply say  draw=black but I need the opposite, a black path with a colored tip.  So this is what I get:        And this is my code:  \documentclass[10pt]{article} \usepackage[a4paper, margin=1cm]{geometry} \usepackage[utf8]{inputenc} \usepackage{rotating} \usepackage{amsmath} \usepackage{pgfplots} \usepackage{tikz}  \usetikzlibrary{arrows,backgrounds,decorations,shapes,shapes.multipart,positioning} \pgfplotsset{compat=1.7}  \begin{document}      \definecolor{blue}{RGB}{0,127,255}      \tikzset{     opera/.style={fill=white, inner sep=0pt, right=3mm, text width= 5cm,font=\footnotesize},     tear/.style={draw=black, fill=blue, -*},.     }      \begin{tikzpicture}  \draw[tear] (12, 5) -- (12,4) -- (10,3) -- (10,2) node[opera] at (10,2){Not the path!};     \end{tikzpicture} \end{document}   I've tried removing as much as possible to make the code minimal so don't worry if you see unused packages or libraries.  I've thought as a possible solution to add an option like >=stealth but trying to set the color using the o or * arrow tips. None worked.

Is "shined" correct? If so, is "he shined X on the tree" also correct?

Recently, I overhead a former professor of mine use the word shined, a word that makes me grammatically uncomfortable.  She used it as following: "Then, after we shined a light on the other ball, what happened?..."  My first question is: Is using shined mainstream, over what sounds better to my ear, shone?  If so, is there any historical flip-flopping between the two usages?  Secondly, if shined is in fact legit, can it be used transitively?  Saying something like,      The light shined all throughout the night.   while odd, doesn't sound as bad to my ear as,     He shined the light on the ball throughout the night.   The latter sounds quite bad to my ear.  Indeed, à propos the original question, can shone — the better sounding alternative to my ear — be used transitively?


How to cast datetime into date in SQL Server 2005

If every point is a local maximum, is it a step function?

What are the functions $f:\mathbb R\to\mathbb R$ such that every point is a local maximum?  Certainly, $f(x)=c$ works for every constant. So does $\lfloor x\rfloor$, as does $I_{\{0\}}(x)=\begin{cases}1&x=0\\0&x\ne0\end{cases}$. Another example is the oddly beautiful $e^{-\lfloor1/\lvert x\rvert\rfloor^{-2}}$. Question is, are step functions such as these the only ones? Are there any examples where every point is a strict local maximum?  (Thomae's function is a near-miss, since the condition doesn't hold on irrational points. Although, most points are irrational, so I guess the term "near-miss" doesn't quite fit.)  EDIT: My definition of step-function is the sum of countably many indicator functions of intervals, $\sum_{n=0}^\infty a_nI_{A_n}(x)$. If it were uncountable, any function would be step, as $\{\alpha\}$ is an interval ($[\alpha,\alpha]$).     This arose when I was thinking about the topological space with basis $\{(-\infty,a]:a\in\mathbb R\}$. If you call that space $X$, then the continuous functions $f:\mathbb R\to X$ are precisely these. I don't have a formal proof but I'm pretty sure (and this would belong in a different question anyway).   Contrast with:

Do Tarski's Axioms prove all of Euclid's Elements?

A fairly self explanatory title; do Tarski's first order axioms given in his famous 'What is Elementary Geometry?' Suffice to prove all of the theorems in Euclid's Elements? (Excluded non-plane geometric theorems).   Now, Euclid spends a considerable amount of time using geometry to develop number theory systematically, including the theory of primes and the like. Tarski proved his axioms complete, but if his axioms suffice for all Euclidean geometry, how does this not contradict Godel's incompleteness theorem since a theory that contains number theory is certainly strong enough for Godel incompleteness to appy?

Is an ellipsis interchangeable with an em dash?

Year 2038 solution for embedded Linux (32 bit)?

What is the proper way to handle times in C code for 32-bit embedded Linux (ARMLinux) to ensure that the code continues to work properly after 03:14:07 UTC on 19 January 2038 (when a signed 32-bit time_t overflows)? Given that time_t is signed 32-bit on the system I have to use, what are the alternatives?  A considerable amount of googling has uncovered nothing of practical use. Everyone seems to assume that we will all be using 64-bit OSs by then, but this patently isn't true of embedded systems.  On the system I am required to use, __kernel_time_t is defined as a long. Which presumably means that there is no kernel facility for 64 bit time. The version of uClibc is 0.9.29.  I can't believe I'm the only one with this problem, and I don't want to reinvent the wheel.


Derivative defined at some point but not continuous there?

I am making an simple 10sec background animation for an intro video for a website using Blender's particle emitter. The particles are rotating and collisions are turned on and I've used a slight brownian force on the particles to give them a bit of motion. The scene is simply a shot of the particles using depth of field for visual effect. I would like to loop the 10 sec video for continuous play.   With that in mind, I am trying to make the transition of the loop seamless. I am thinking of using a cross or gamma cross effect to make the transition appear seamless.   Is there a better way for to achieve what I'm after, or will this approach even work?

Add a community feedback step before implementing policy or process changes

In a recent , Teresa Dietrich announced this process for policy changes:     We have defined a standard process for new policy or process review that includes Community Managers, employees who are long-time community members, and Moderators before being shared and put into place. Our plan is to provide new policies to the planned Moderator Council for feedback periods before they are made official. We will then share it with all Moderators through the Stack Moderators Team for advance notification. We value the deep understanding that moderators on the network have of their communities and users, and welcome honest, respectful feedback from the greater Stack Exchange Community.   One of the complaints that I have heard most frequently in the past few months is that users find out about policy changes only after the discussion and debate have been completed in secret, without them. The above process seems to indicate that this will continue - that moderators are the only ones who will receive advance notice of proposed changes and be allowed the opportunity to provide feedback before a final decision is made.  Let's add a community feedback stage. After feedback has been received from moderators, the proposed change should be posted on Meta or another suitable place for community feedback. To be clear, I'm not asking for the community to be given absolute veto power over a change, but only asking for advance notice and an opportunity to be heard before a final decision is made.

Integrating $x^2e^{-x}$ using Feynman's trick?

In the second episode of season $8$ of "The Big Bang Theory," which aired yesterday night, it is stated that one can integrate $x^2e^{-x}$ by using Feynman's trick of differentiating under the integral. Is this actually true, and if so, how to do it? And is it "better," in any sense, than the usual way of doing it by integration by parts?

Graphic drivers for Asus N76VZ (NVIDIA GeForce GT 650M)

I just installed the latest Ubuntu 13.10 and I'm trying to figure out what drivers I should install and how to do it. I have an integrated Intel GPU and a Nvidia GeForce GT 650M that should work together according to the Optimus technology. The software updater doesn't show any additional third-party driver available, though, and this makes me think that maybe there are no drivers for Linux 3.11 yet. So the question is: do I have to install additional drivers over the ones preinstalled by the system? If yes, where can I find them?  Thank you and please forgive the mistakes I could have done, but I'm completely new to Linux and I'm trying to get started..

So I've been looking around for an answer, and I can't seem to find anything resolved in terms of the problem I'm having. Here's the deal, I have an ASUS laptop that has Windows 8 preinstalled on it. It has 6 GB of ram with a 64-bit operating system. The only problem is that I'm sick and tired of Windows 8. I was hoping I might be able to install Ubuntu, but I've heard it's almost impossible. I've read that it can be done though... The only problem I'm having is how I might be able to do so. If anyone could give me a step-by-step guide or a link somewhere that is VERY helpful, especially for a first-timer like myself, I'd be very appreciative.   Thanks in advance!

How to redirect output to a file from within cron?

I have a backup script which I need to run at a particular time of a day so I am using cron for this task and from within cron am also trying to redirect the output of backup script to a logfile.  crontab -e  */1 * * * * /home/ranveer/backup.sh &>> /home/ranveer/backup.log   In the above cron entry I am redirecting both stderr and stdout to a log file.  The above cron job executes fine according to syslog  and it performs the task mentioned in the backup.sh file but it doesn't write anything to the log file.  /var/log/syslog  Oct 19 20:26:01 ranveer CRON[15214]: (ranveer) CMD (/home/ranveer/backup.sh &>> /home/ranveer/backup.log)   When I run the script from cli it works as required and output is written to a log file  ranveer@ranveer:~$ ./backup.sh &>> backup.log  ranveer@ranveer:~$ cat backup.log Fri Oct 19 20:28:01 IST 2012 successfully copied testdir test.txt successfully copied ------------------------------------------------------------------------------------- ranveer@ranveer:~$    So, why the output of file is not getting redirected to the file from within cron.

Benefit and disadvantage of linked list or array implementation of list

What are the advantages a Linked-List implementation of a List has over an Array-based implementation of an array and vice-verse?  For starters I know that linked-list uses up more space than an array because it has to use the extra 4 bytes of space to hold a reference to the next node and an array doesn't have to do that. So array uses less space.  Advantage linked-list has over an array implementation is that array has a fixed size at initialization and you have to write code to increase the size of the array so that may be a disadvantage when compared to linked-list implementation.   Any ideas on anything else for advantage-disadvantage?


Why do USB Keyboards work instantly in DOS / BIOS but have to install drivers in Windows?

For example, if you're at your BIOS screen or a DOS environment, when you plug in a new USB keyboard, it appears to be usable almost instantly. But, if you are in Windows and plug in a new keyboard, it has to install drivers or updates, making it unusable for the duration. I realize that you don't get full features of certain keyboards in DOS, so Windows has to install drivers for added functionality. But why doesn't the keyboard start working with basic functionality instantly and continue to install the rest of the drivers if needed, obviously the technology is there to make this happen.  This is more for curiosity than to solve a problem, but any insight is appreciated!  Thanks


Converting media server to Ubuntu: Do I need to convert NTFS drives with movies?

I'm a rookie in the Ubuntu world but want to learn.  I have a media server running Windows 7: four physical drives containing movies. I want to convert the media server to a simple Ubuntu machine.

They are almost full :)   I guess I can back them up, one by one, to a temporary external drive if necessary...

Academic publishing: why placing figures on top/bottom of pages in single-column layout?

When you turn in a manuscript to an academic publisher, they may insist (referring to their style guide and publication process) that all figures are placed on top/bottom of the manuscript's pages rather than exactly where you need them (e.g., in the middle on one page and on top on another page). Why? Assuming single-column layout and that no huge line stretching, no huge vertical gaps, and no vertical overflows occur, what good reasons could exist nowadays for figures to be moved out of the very place where you need them?  An example could be the figures in the : they are placed typically where the reader needs them rather than always at the top/bottom of the pages.

Convergence in Distribution of the maximum of a sequence.

I've come across this problem which has completely stumped me. It goes as follows:  Let $(X_n)$ be a sequence of independent and identically distributed exponential random variables with parameter $\lambda$. Let $M_n$ denote max{$X_1,...,X_n $}. Show there exists a random variable $Z$ such that $M_n - \frac{1}{\lambda} \log (n) $ converges in distribution to $Z$.  Now this problem seems really hard, so I tried proving it for convergence in probability to see if that would work and imply convergence in distribution, but I couldn't get very far. Moreover, calculating the expectations also seems non-trivial due to the fact that it would be hard to integrate $M_n = \frac{1}{\lambda} \log n$.  Any suggestions and ways to approach this problem would be greatly appreciated as I've been stuck on this for a long time. Should I try using the Skorohod equivalent statement?  Thanks.

Using the definition.  $a_n = S_{n} - S_{n-1} $  $$a_n = \frac{n-1}{n+1} - \frac{n-2}{n}$$  $$= \frac{n(n-1) - (n-2)(n+1)}{n(n+1)}$$  $$= \frac{n^2-n - (n^2-n-2)}{n(n+1)}$$  $$= \frac{2}{n(n+1)}$$  Hmm, I can use PFD on this to make it.   $$= \frac{2}{n} - \frac{2}{n+1}$$  Is this right? What about n = 0   The sum is 1 right? cus lim at $\infty$ ?


Ubuntu 18.04 LTS Spectre/Meltdown Status

I could not find any official Ubuntu information on that issue.  If I check the official statement:  there is only information on Ubuntu 17.10 and earlier. Is it possible to complete the "Kernel Mitigations" table on the wiki web page mensioned above with the Ubunut 18.04 LTS?

Is there a way to test for snowballs that have broken?

I know you can test for arrows in the ground using:  /testfor @e[type=Arrow] {inGround:1b}   But is there a way to test for snowballs that have broken (hit something)?


Shell, Concatenating 2 strings to reference a 3rd variable

I am trying to do the following in my script:  #/bin/bash -x var1=www var2=www2 var3=www3 var4=www4 for i in 1 2 3 4; do    echo \$var$i done   Obviously, this doesn't work as expected and results in the following output:  $var1 $var2 $var3 $var4   How can I dynamically reference the variables in my loop?


I just started to learn LaTeX after seeing some amazing examples of scientific articles produced using it; I was also told that, unlike some other other text programs, LaTeX automatically produces articles respecting some publication standards. Well, after playing around with it for a while, I have to say my PDFs are anything but pretty, particularly when compared to those examples I mentioned before! My margins are really too large, my font size seem to be too small, my default paper is not A4 (and even when I set it manually to A4, the top margin then take an even more ridiculous amount of space). After reading a bit, I obviously found out how to control these elements, but the whole point for me to start learning LaTeX was not to fool around with such things. So here is (are) my question(s): am I doing something wrong? Is all this a matter of configuration? Or am I being delusional and my output PDFs actually ARE all in the expected standards? (I am using MiKTeX, and I tried three editors so far: TeXworks, LyX and WinEdt8)  Here are some examples I found on the internet of what I am talking about. The first seems to me as a simple article without any extra layout commands. Notice the size of the margins, fonts, etc. This is how my PDFs look like.   Now compare that previous PDF with this one here:  Unfortunately this one is written in two column format but I couldn't find another example online with just one column. Note how everything is balanced, how the margins are small, how the font is smaller as well, etc.  As a final note, I just would like to say that I really don't mind learning LaTex and that I am not expecting to produce amazing documents from day one; I just think that, in case my problems here are really sound, then I might have came to LaTeX with the wrong set of mind.  Thanks a lot!


The given question:  Let $k$ be a ﬁeld and $n \in \mathbb{N}$. Show that the centre of $\operatorname{GL}(n, k)$ is $\lbrace\lambda I\mid λ ∈ k^∗\rbrace$.  I have spent a while trying to prove this and have succeeded if $ k \subseteq \mathbb{R}$. So I imagine there is a nicer way to go about this. I have seen people saying take matrices where every element except one is zero in proving similar results but such matrices are not in $\operatorname{GL}(n,k)$ as they are not invertible.  What I have done.  I have said let $B \in$ Center then $B$ commutes with everything in $\operatorname{GL}(n,k)$. So take a permutation matrix, $P$ which swaps rows $i,j$ $P \neq I$. From this you can deduce that $B^T = B$ and that $B_{ii} = B_{jj}$. We can use the fact that $B$ is symmetric to find an orthogonal diagonalisation of $B$ by the spectral theorem.  This gives $QBQ^T = D \rightarrow B=D$. And as $B_{ii} = B_{jj}$ we can say $B = k * I$.   But the spectral theorem requires $B$ to be a real matrix.   How do I prove this for a general $k$?.

10.12.4 Apple Upgrade breaks LaTeX; Fixed?

The 10.12.4 upgrade to Apple's Sierra apparently breaks LaTeX: see  here () and here ()  Does anyone know if Apple has fixed this issue?  EDIT: On April 17th, two weeks after Richard Koch (author of Texshop) stated that "Apple is aware of this bug" I asked in the "duplicate" question if Apple had fixed the bug. There was no response, and we're now one month down the road from Apple's learning of the problem.   The initial upgrade from El Capitan to Sierra did not create this issue; it was only reported in the two questions I cited and the thread I posted in as a consequence of the recent .4 upgrade.   There's no point in upgrading to Sierra .4 if it breaks LaTeX, so it's strange to say that it would be more helpful if I created a problem that I'm not interested in encountering.  There is no further news on tex.stackexchange as to whether the problem has been fixed. Who would want to experiment under these conditions?

What is a quick way to farm demon skin on lvl 70?

I found a set plan today, which requires Demon Skin as an ingredient. I was trying to look it up on Battle.Net, but there seems to be no page for that material and most stuff I found on the internet was outdated. So what is the best and quickest way to farm Demon Skins? Does it drop in a specific place or is it just random? I never seen that one at all.


Problem using xargs --max-args --replace with default delimiter

This works as expected:  $ echo a b c | xargs --replace="{}" echo x "{}" y x a b c y   This does too:  $ echo a b c | xargs --max-args=1 echo x x a x b x c   But this doesn't work as expected:  $ echo a b c | xargs --max-args=1 --replace="{}" echo x "{}" y x a b c y   And neither does this:  $ echo a b c | xargs --delimiter=' ' --max-args=1 --replace="{}" echo x "{}" y x a y x b y x c  y   I expected this output:  x a y x b y x c y   As a workaround, I am using printf and two xargs, but that is ugly:  $ echo a b c | xargs printf '%s\0' | \ > xargs --null --max-args=1 --replace="{}" echo x "{}" y x a y x b y x c y   Any idea why this is happening?


Feature Request: allow closed questions a 2nd (pointless) life

To broadly paint my understanding, Stack Overflow doesn't want a reputation of more frivolous open questions and emotional debate. But it also wants to foster use and value. These are at odds whenever a question is closed due to being open-ended or prone to opinion and debate, particularly when it's about the pros and cons of software (sure - these things can be heavily opinion-based, but opinions are just baby facts trying to grow).  I suggest that when such questions are closed, that they be frozen (as normal) and cloned into a separate environment where answers can continue to be submitted and commented on. In order to lower the stakes (relieve pressure that can lead to argumentative responses and mistakes in human reasoning), it came to me that this could be a place where reputation points are not registered. Or where some other incentive structure is in place to dissuade uncharitable conversation.  Questions that are closed are often the most interesting and it's a great shame they're not more fruitful places. Don't kill those little baby facts before they get a chance!


what is the difference between const, readonly and get in a static class

I have a question. Lately I have caught myself using 3 different lines of code which upon closer inspection looks and feels the same.  public static class constant {     public static readonly int val1 = 5;     public const int val2 = 5;     public static int val3 { get { return 5; } } }   my question is, are they the same and should one be used over another? if so. When?  also as a extra question in visual studio why are they all represented differently in intellisense?


I have made a project whose structure is like this    When I run my index.html from firefox, it is working fine.  But I open it with my chrome it is giving CORS error.     Now my problem is that chrome doesnot support file:// protocol ajax request & as I have distribute to my project to others I don't want other to run on firefox only.  Internally I am using ajax call in project, to load the resources. Can Somebody suggest how to bypass that ajax call to load resources?? Is there some solution or any third party js which can help me.  Note: Please don't suggest to use XAMPP, apache etc where I can put my project and run as localhost for chrome as I don't want user to force to download these to run my project. Please give other useful solution where I can do some change in code & it works for everyone.  Here are the links from which you could understand my problem better.


Convert String (MMM, dd, YYYY hh:mm AM/PM) to datetime - three letter month

How can we convert "Dec 5, 2018 3:14 PM" (with three letter month) to datetime format. Tried both Parse and ValueOf and they did not work.  DateTime.Parse('Dec 5, 2018 3:14 PM'); DateTime.ValueOf('Dec 5, 2018 3:14 PM');   We have this date in a json file that we need to process.  Even this did not work  system.debug(Json.deserialize('Dec 5, 2018 3:14 PM', DateTime.Class));


In "Living Witness," what happened after the doctor was deactivated and nine Kyrian ships attacked?

The Voyager's story from the doctor ends with this:     EMH: Computer, freeze programme. A tragic, needless death, but as you   can see, Voyager was not responsible. After Tedran was killed, Voyager   was attacked by nine Kyrian ships. My programme was disabled, most   likely when they stole my backup module. The next thing I knew, I was   standing next to this gentleman seven centuries later.   What happened after that? The  plot summary seems to be unrelated.

How can I replace a relay with a MOSFET Transistor?

I have this working         – Schematic created using   An Arduino commute both relays and a power adapter charge each battery at a time.  I would like to replace each relay by a MOSFET. How can I do that?  I think the solution bellow will not work because DRAIN is always connected to SOURCE and this will short circuit batteries. MOSFETS only isolate from SOURCE to DRAIN.  When the D9 is HIGH, D10 will be LOW so the power adapter will never be charging both batteries simultaneously.          Sorry for the messy schematic.  Thank you very much.


What happens to spirits/souls of other creatues than Elves and Men after their death?

Silmarillion tells us what happens to the souls of Men and Elves:     ... For the Elves die not till tile world dies, unless they are slain or waste in grief (and to both these seeming deaths they are subject); neither does age subdue their strength, unless one grow weary of ten thousand centuries; and dying they are gathered to the halls of Mandos in Valinor, whence they may in time return. But the sons of Men die indeed, and leave the world; wherefore they are called the Guests, or the Strangers. Death is their fate, the gift of Ilúvatar, which as Time wears even the Powers shall envy. ...   But what happens to the souls of other creatures likes dwarves, hobbits, ents, orcs, uruk-hai, maiar, balrogs (and other conscious creatures I might have forgotten)?


Need some interpretation with plain English for a part in Bayesian Statistics with Beta proability distribution?

Can somebody explain why equation (6.3) and (6.4) are shown in the book and what the author is trying to say?   It feels to me that I am reading the text but I don't think I getting the true meaning that the author is trying to say.  I am reading the book, "Doing Bayesian Data Analysis" and the page is "127".


This question isn't just about kilogram-meters, it's about multiplied units in general.  I have a good mental conception of divided units, e.g. meters per second or grams per cubic meter.  Meters per second just (usually) means how many meters are traversed by an object each second.  Simple.  But I don't really have a mental conception of what it means when units are multiplied, e.g. a kilogram-meter.  Can anyone explain in simple physical terms what a kilogram-meter is?


Are there any theories of moral responsibility that don't require free will?  Sam Harris  and attempts to construct some form of , but "The Moral Landscape" didn't sound very convincing to me exactly because the notion of responsibility wasn't there, it was all about optimization of multidimensional functions. (Disclaimer Or may be I missed/forgot the responsibility and need to reread the book).   Are there other attempts to formulate the responsibility without appeal to free will?


How can I stop the Windows cursor from appearing over Skyrim?

I've seen tons of problems with Alt-Tab and the desktop cursor showing up.   But my problem is that the desktop cursor shows up without ever tabbing out. It seems like it happens when I'm running (shift) and moving (w) forward and/or turning (a).  When I do that, my computer beeps and the Windows cursor shows up. That makes it seem like a Sticky Keys problem, but I don't have Sticky Keys turned on. Is there something I'm missing?  I'm using dual monitors and have Windows 8.1.


Php broken, "held broken packages" error on install

I've completely destroyed everything and now php wont install.  I had php5.4 and everything was great.  I then needed to run Magento locally which wasnt working.  I saw one of the requirements was php5.3 so I downgraded using a script i found online but then PDO wasnt working.   I stuffed about for a few hours following what people said online, eventually nothing was working so i purged php to do a fresh install of php5.4 to start again from scratch and figure out my problems.  After i purged, i came to reinstall Php5 using apt-get install php5. Once the script ran i got the following output:  Reading package lists... Done Building dependency tree        Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:  The following packages have unmet dependencies:  php5 : Depends: libapache2-mod-php5 (>= 5.4.9-4ubuntu2.4) but 5.3.10-1ubuntu3 is to     be installed or                  libapache2-mod-php5filter (>= 5.4.9-4ubuntu2.4) but it is not going to be installed or              php5-cgi (>= 5.4.9-4ubuntu2.4) but it is not going to be installed or              php5-fpm (>= 5.4.9-4ubuntu2.4) but it is not going to be installed     Depends: php5-common (>= 5.4.9-4ubuntu2.4) but 5.3.10-1ubuntu3 is to be installed E: Unable to correct problems, you have held broken packages.   I then googled for ages and ran commands like clean, update, upgrade, -f install and a few others. I come back to install php and i get the same error.  How can I reinstall Php so it works again.


Which Ubuntu distro is right for this 2-in-1?

I own a Dell Latitude 11 inch 2-in-1 ... it has a m5-6Y57 processor, 8GB of RAM and 256GB SSD.. Which Ubuntu distro is right for this 2-in-1 ? I want to read ebooks on it so the distro has to support screen rotation and gestures...I also want to take notes with it...The 2-in-1 is Wacom AES enabled and has an active pen.  I guess Ubuntu gnome is the right choice for this laptop...but will it run smooth on this 2-in-1 ? what other distros should i look at ?    I also have a Dell inspiron 3179, which has m3-7Y30 processor, 4GB of RAM and 250GB SATA3 SSD ...   Which Ubuntu distro is right for this one ? I am looking at elementary OS and Xubuntu at the moment...Do Xfce and Pantheon support screen rotation and gestures ? i intend to read ebooks on this too...but no note taking as the touchscreen is not AES and doesn't support an active pen.  What other distros do you recommend ?  I know there is Ubuntu Mate and LXQT/DE....but these don't have touchscreen functionalities...


Why Didn't Dumbledore Hear the Basilisk?

J.K. Rowling has stated that Dumbledore was fluent¹ in English, Mermish, Gobbledygook, and Parseltongue. If this is so: Why didn't Dumbledore hear the Basilisk during the events in Chamber of Secrets? There's nothing to indicate Dumbledore was hard of hearing (no ear trumpet!) and he spent enough time in the castle that surely he would have been near the Basilisk at least once or twice. Is there any canon-based explanation for this?  ¹What J.K. Rowling actually said was that Dumbledore understands Mermish, Parseltongue, and Gobbledygook. That's enough of a difference from fluency that I felt I should mention this. Further, J.K. Rowling has this to say about learning Parseltongue:     Q: Since Ron is able to speak Parseltongue in the last book, does that mean that Parseltongue is a language that most witches and wizards can learn or must a person be born with some ability to speak Parseltongue?   JKR: I don't see it really as a language you can learn. So few people speak it that who would teach you? This is a weird ability passed down through the Slytherin blood line. However Ron was with Harry when he said one word in Parseltongue, which I do not know so I cannot duplicate for you, but he heard him say "Open," and he was able to reproduce the sound. So it was one word. Whether he could learn to speak to snakes properly is a separate issue. I don't think he could. But he knew enough, he was smart enough, to duplicate one necessary sound.      So where does this leave Dumbledore when it comes to Parseltongue?


How to get jquery to read a dynamic divs?

I have two divs #apparatusSection and #firefighterSection  #apparatusSection is a static div but #firefighterSection is dynamically created when I click the Add Apparatus button. When i do this, the Add Firefighter button doesn't do anything as I presume it cannot read the dynamic div which was just created. The add apparatus works as expected. I can also get the add firefighter to work if I statically set up the div.  HTML:

             <button id="addApparatus" name="addApparatus" class="btn btn-primary">Add Apparatus</button>

   JQuery:      var countApp = 0;     var countFF = 0;     $(function () {         $('button#addApparatus').click(function () {             countApp += 1;             $('#apparatusSection').append(' \
