I've followed  to install phpMyAdmin on the server which uses ubuntu 14.04. I've entered all commands and restarted apache, but when I open this path through the browser:  http://domain_name_or_IP/phpmyadmin // I replace my real IP with domain_name_or_IP   It throws:  Not Found  The requested URL /phpmyadmin was not found on this server.  Apache/2.4.7 (Ubuntu) Server     Also here is the result of this command:  root@ubuntu:/etc/apache2/conf-available# ls     See? there is not any file related to phpMyAdmin. Does anybody know what's wrong?
When I go to localhost/phpmyadmin I get the apache "Not Found" error (404). However, I can load html pages, and run php pages (such as &lt;?php phpinfo(); ?&gt;). And phpmyadmin is installed.  balter@homedevbox:~$ aptitude search phpmyadmin i   phpmyadmin                                               - MySQL web administration tool   I also installed the standard ubuntu LAMP stack and set passwords for mysql and all that.  What could be the problem?  EDIT: Here is where my phpmyadmin files are.  balter@homedevbox:/var$ cd / balter@homedevbox:/$ sudo find . -type d -name phpmyadmin ./var/lib/mysql/phpmyadmin ./var/lib/phpmyadmin ./etc/phpmyadmin ./usr/share/phpmyadmin ./usr/share/dbconfig-common/scripts/phpmyadmin ./usr/share/dbconfig-common/data/phpmyadmin ./usr/share/doc/phpmyadmin

A composite integer n is a Carmichael number if the only Fermat   witnesses for $n$ are those $a \in \mathbb Z_n^+$ which are not   coprime with $n$. The smallest example of such a number is $561 = 3 ·  11 · 17$   I think I understand the definition, but I don't quite understand why is the smallest Carmichael number is the above mentioned number. Please clarify. Can noindex tags on several pages affect the overall SEO or ranking on Google? Some SEO Gurus assured me that noindex attributes are good to devalue the unimportant pages.   When I asked in the moz Q and A, they're quite sure that having noindex on the bulk of the articles on the website can harm overall SEO ranking.   Which is true? If I do not edit the .bashrc or other config files, the environment variables that I've setted are gone when I logout, or turn off the terminal.   What I'm curious is, where are those 'temporary' env vars saved in?   As I guess, they might be in the memory. That makes sense because they will disappear when the terminal is turned off(equals the terminal I was using is gone from the memory). Am I correct? Four balls with different colors in a box, how many times do I need to pick to see all four colors? If I have a dataset with a very rare positive class, and I down-sample the negative class, then perform a logistic regression, do I need to adjust the regression coefficients to reflect the fact that I changed the prevalence of the positive class?  For example, let's say I have a dataset with 4 variables: Y, A, B and C.  Y, A, and B are binary, C is continuous.  For 11,100 observations Y=0, and for 900 Y=1:  set.seed(42) n &lt;- 12000 r &lt;- 1/12 A &lt;- sample(0:1, n, replace=TRUE) B &lt;- sample(0:1, n, replace=TRUE) C &lt;- rnorm(n) Y &lt;- ifelse(10 * A + 0.5 * B + 5 * C + rnorm(n)/10 &gt; -5, 0, 1)   I fit a logistic regression to predict Y, given A, B and C.   dat1 &lt;- data.frame(Y, A, B, C) mod1 &lt;- glm(Y~., dat1, family=binomial)   However, to save time I could remove 10,200 non-Y observations, giving 900 Y=0, and 900 Y=1:  require('caret') dat2 &lt;- downSample(data.frame(A, B, C), factor(Y), list=FALSE) mod2 &lt;- glm(Class~., dat2, family=binomial)   The regression coefficients from the 2 models look very similar:  &gt; coef(summary(mod1))               Estimate Std. Error   z value     Pr(&gt;|z|) (Intercept) -127.67782  20.619858 -6.191983 5.941186e-10 A           -257.20668  41.650386 -6.175373 6.600728e-10 B            -13.20966   2.231606 -5.919353 3.232109e-09 C           -127.73597  20.630541 -6.191596 5.955818e-10 &gt; coef(summary(mod2))               Estimate  Std.

However, this is a single, contrived example, and I'd rather know for sure. File upload to Heroku not working I am looking for a short story I read long ago about the phone system 'waking up'. It talks about how the phone system had just reached the number of connections as the number in the human brain. They lead you somehow to wonder (maybe characters speculating?) and it ends with a 'baby cry' of all the phones in the world ringing. I think I read it at least 20 years ago, maybe as many as 30. I think it was after 1978 because I think it was after I went to work at Bell Labs - so the phone connection resonated:-). It was definitely pre-internet.   What was the title? Who was the author? Any more on the plot since my memory is very hazy? I remember really liking the story and this site has got me thinking about my ATF's. It seems to me that the terms "Teaching Assistant" and "Instructor" refer to a variety of positions. At some places, a teaching assistant is responsible for things like helping the actual lecturer by handing out papers, grading homework, etc., and instructors hold recitation sessions.  At other places, I saw the term "instructor" referring to the lecturer giving the course, while a teaching assistant is the person doing anything else (recitations, grading etc.).  Is there some widely accepted definition of the two positions?  For context: The question arose because I wasn't sure whether I'm using the correct terms in my CV -- I am a math graduate student, and I would like to make a distinction between jobs in which I only graded course assignments/final exams, and courses in which I held recitation classes* (and also participated in grading the final exams). Is it OK to use "Instructor" for the latter? What should the former be referred to as?  *In the course I'm currently teaching, the recitations are planned and written by the ones giving them (without the professors' supervision). Also, the people giving the recitations are not necessarily grad students (some already hold a PhD). I'm elaborating on that because from what I've seen, some of it could be relevant for the definition of the job. In previous versions of the OS in the security pane, you are provided an option of:    But in this version there is no option anywhere:    Is there a way that I can turn on anywhere? (via Terminal maybe?) We know that wizards in the Harry Potter universe are subject to regular physical harm (e.g. witness injuries from being hit by Bludgers or just colliding with things when playing Quidditch).  Therefore, it's almost a certainty that an average wizard would be vulnerable to, say, a bunch of bullets.   There may likely be spell(s) to protect from projectiles - witness Dumbledore's  deployed when Voldemort sent a bunch of glass at him during the  at the end of Harry Potter and the Order of the Phoenix (according to , possibly an unusually powerful Protego or the Silver shield).   But:   those spells obviously take effort/energy/time to cast (not everyone's Dumbledore) AND more likely than not most Death Eaters wouldn't recognize a Muggle gun for a threat (or realize what kind of threat) till too late.   So, the guns should at best allow an over-matched OotP member (e.g. Harry or Hermione) to greatly equalize the power between any regular Death Eaters and themselves, and even perhaps help against Voldemort (who can't be killed with a bullet, but, at best, would need to expend magical energy and time into conjuring a shield, and, at worst, be stopped/interrupted/driven off).  So I'm looking for an explanation - ideally in-universe, but possibly just some statement by JKR - of why the Muggle-born OotP - who are likely very much at ease AND familiar with Muggle technology and live in the late 20th century - do not use guns. Or, for that matter, ANY Muggle technology of the late 20th century? Cue Arthur C. Clarke's "indistinguishable from magic" meme.  Even if they are on some kind of idiotic moral crusade to never kill their opponents (even the Jedi aren't this dumb), given the time-frame, non-lethal weapons would have already existed, such as rubber bullets and tasers.  NOTE: Please don't offer the "if they do it, Death Eaters would start using guns as well" theory. First, Death Eaters would have used the guns if they knew how to, anyway. Second, the guns, like any "secret weapon", could be reserved for strategic battles, say the defense of Hogwarts in Deathly Hallows.    The origin of the question stems from two things.  First, Harry's fascination with all things that are different in the magical world (e.g. moving photographs), based on his knowledge of the Muggle material world, as well as the somewhat amusing cluelessness of the "Muggle artifacts" expert, Mr. Weasley, regarding Muggle items and how they work.   Basically, from the books, it's clear that the Wizarding world wouldn't know details about guns or what they are for or how they work.  The second thing is it's clear, at least initially, that wizards are afraid of Muggles finding out about them. Hence all the efforts to cloak their society (basically, do you REALLY want every Muggle gunning for you, even with Magic)? The idea of how control over the Muggle world seems to be more indirect, by Death Eaters asserting mind-control over the government. This means there's an implicit understanding by Death Eaters that they don't stand a chance against armed Muggles even given the magical disparity.  Considering Harry and Hermione's overall adaptability and inventiveness (and brains in the latter case), it's mind-boggling that the idea of fighting Death Eaters with modern technology completely slipped their mind. I mean, it's a basic part of human myth (see Steel vs. Magic themes in Conan books, or Beowulf, or heck, A Yankee in King Arthur's Court). So it's not like the idea of using technology against magic would be impossible to come up with. The question begs itself - why not? Considering the fact that Rowling generally tried to be logical and consistent in building the HP universe, I feel like there must be some in-universe explanation for this that I just didn't notice.   (in-universe answers only unless there are some authoritative out-of-universe statements that are part of canon). Using a question mark mid-sentence How do I install the latest version of EMACS and pick the appropriate UI? I'm running the latest Kubuntu (12.04 beta 2) and I would like to run the latest emacs (currently v24). The repos are one version behind. What's the best way to install v24 or later (and avoid future version conflicts)?  Also, is there any reason not to aways use the GUI version of emacs if X is running? For example, could I set the GUI emacs version as the default text editor and use it to edit cron jobs (crontab -e)? I'm assuming the answer is yes, but since I haven't done that yet (my default editor is nano), I want to check if there are reasons I should leave nano as the default editor.  Usually when I'm working on the command line I end up using nano. Now that I think about it, I have no idea why I keep doing that. Is there any downside to calling a GUI editor when working in an X terminal?  EDIT: I briefly tested these two versions   GNU Emacs 24.0.94.1 (x86_64-pc-linux-gnu, GTK+ Version 3.3.20) from  GNU Emacs 23.3.1 (x86_64-pc-linux-gnu) installed by default in Kubuntu.   .  Unfortunately (for me) the defaults installed version (23.3.1, 23.3+1-1ubuntu9) is the nox version.   Package: emacs23-nox Status: install ok installed Version: 23.3+1-1ubuntu9 Replaces: emacs23, emacs23-gtk, emacs23-lucid   The package with version 24 opens in GUI mode by default. That's what I prefer. Some of the version 24 changes that interest me are listed in the references below.   But there appear to be a multitude of different packages and versions I could install.

This is an exercise in complex analysis:     Let $\Omega\subset{\Bbb C}$ be open and bounded, and $\varphi:\Omega\to\Omega$ a holomorphic function. Prove that if there exists a point $z_0\in\Omega$ such that   $$ \varphi(z_0)=z_0\qquad\text{and   }\qquad \varphi'(z_0)=1 $$   then $\varphi$ is linear.   I'm trying work out the case $z_0=0$ first, in which $$ \varphi(z)=z+\sum_{n=2}^{\infty}a_nz^2. $$ It suffices to show that $a_n=0$ for all $n\geq 2$. If let $$ \varphi(z)=z+a_2z^2+O(z^3) $$ then  $$ \varphi^k(0)=z+ka_2z^2+O(z^3), $$ and $$ \varphi^k(0)=0,\quad (\varphi^k)'(0)=1. $$ If one can show that $\{ka_2\}_{k=1}^{\infty}$ is uniformly bounded, then one at least has $a_2=0$.
