What would Voldemort have done had he won? This might sound like speculation, but can it be reliably predicted from canon what Voldemort would have done after he won, were he successful in defeating Harry and the Order?  Would he just rule over the wizard world and keep up the masquerade, or would he try to take over the whole Earth by starting a (dark-)wizard vs. muggle war? Showing $\sum\limits_{p \in P} \frac{1}{p}$ where $P$ is the set of all primes is divergent Is something wrong with StackOverflow's spam filter? Recently there have been huge numbers of spam topics related to football streaming. They have all been spam flagged and deleted but there are more getting posted all the time, I just flagged another 6 or so a few minutes ago. This has been going on for around 3 days now with these topics getting constantly posted over and over again in the  tag. I want to show the IP address like below  lo : 127.0.0.1  eth0 : 192.168.5.123 eth1 : 192.172.0.212 wlan0 : 10.1.0.124   I'm able to print all IP address by ifconfig | awk '/inet addr/{print substr($2,6)}'. But it is only printing the IPs. Every system have their own interface names and addresses. So my script has to show their interfaces with respect to IP addresses. Can I use a variable which has a non-linear relationship to the dependent variable in logistic regression? Let's say I am building a logistic regression model where the dependent variable is binary and can take the values $0$ or $1$. Let the independent variables be $x_1, x_2, ..., x_m$ - there are $m$ independent variables. Let's say for the $k$th independent variable, the bivariate analysis shows a U-shaped trend - i.e., if I group $x_k$ into $20$ bins each containing roughly equal number of observations and calculate the 'bad rate' for each bin - # observations where y = 0 / total observations in each bin - then I get a U shaped curve.  My questions are:   Can I directly use $x_k$ as input while estimating the beta parameters? Are any statistical assumptions violated which might cause significant error in estimating the parameters? Is it necessary to 'linearize' this variable through a transformation (log, square, product with itself, etc.)? Uninstalling Homebrew messed up git I uninstalled Homebrew using .  After running the above commands, I can't find .bashrc and .bash_profle. All files are gone from Documents , Desktop and Downloads :'(  When I do git status on /Users/ava it shows:  # On branch master # Untracked files: #   (use "git add &lt;file&gt;..." to include in what will be committed)  ... all the files which are in /Users/ava   history   113  cd `brew --prefix`   114  rm -rf Cellar   115  brew prune   116  rm `git ls-files`   117  rm -r Library/Homebrew Library/Aliases Library/Formula Library/Contributions   118  rm -rf .git   119  rm -rf ~/Library/Caches/Homebrew   120  sudo chown -R $USER:admin /usr/local   121  ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"   122  brew doctor   What just happened? Valid US visa on expired passport. Can I travel to the US? $\operatorname{Aut}(\mathbb Z_n)$ is isomorphic to $U_n$. I'm interested if any of the following explanations have enough predictive capability to explain the observations we see today. The claim is that the Universe is not expanding, and that red-shift of light is caused by:    Though a couple of these are simply ridiculous, I'm still interested. Keep in mind that I am not a creationist, but am looking for reasons to see if any of these are valid or invalid. Here are two sentences:        Once he got the passport, he went to the Chinese consulate in Toronto and applied for a visa.   Once he got the passport, he went to the Chinese consulate in Toronto to apply for a visa.      Are the two sentences grammatical, and do they sound natural?  If they are both fine, what's the difference? Delete all lines in Notepad++ except lines containing a word I need? As you know, we can enable the spell checker on single line text boxes in the following way:    We have to enable it every time for checking words.  How can we enable it forever, so it doesn't need to be enabled each time? What are the limits on how I can cast, change, and retract votes? What limits are there on how I can vote?  How often can I vote? How do my votes become locked/unlocked? Pass shell variable as a /pattern/ to awk I have a distribution of microparticles that follows a lognormal distribution. The cumulative distribution function thus is given by:  $$ F_X(x;\mu,\sigma) = \frac12 \operatorname{erfc}\!\left(-\frac{\ln x - \mu}{\sigma\sqrt{2}}\right) $$ $$ \mu = ln(M) + \sigma^2 $$  Now, the plot of the distribution function should be exactly the same no matter if the particle diameter $x$ is given in micrometers or meters (as long as I adapt the x-axis accordingly of course). However, this only works if I only convert $x$ and $M$, while not touching the numerical value of $\sigma$, and I don't understand why. $F_X$ has to be unitless, so $x$, $\mu$ and $\sigma$ should all have the same unit, right? Mobile web refresher, part 2 After a sizeable amount of work we are releasing a new version of the mobile web site, this time focusing on the question and answer page. We have also fixed or implemented a minimal large part of the issues and requests mentioned in the . Changes Question and answer page  SVG icons for upvote, downvote, favorite, comment upvote white background color for legibility general styling issues with notices (they actually exist now) bounty link is now in question menu (next to flag)   Ask question page  general styling and sizing of element use of placeholders where appropriate instead of page text styling of error messages   Pop-ups  Popups are now inlined in the page instead of being sometimes floating and draggable Many overdue styling issues Close button is SVG Flag indicators are readable Buttons   Misc pages  404 page did not exist. Now it does. Login, logout are formatted Pre-ask and pre-answer warnings are now formatted  Bugfixes  made search magnifying glass bigger fixed language in user timeline so it's consistent with the desktop site added login link on top bar made topbar icons ever so slightly smaller  Restating the obvious: send your &lt;3 to  and   for the most excellent design! Feedback , bugs and suggestions while we move to the next iteration? Please mark bugs with Is there a way to force a C# class to implement certain static functions? Possible Duplicates:             Voting on questions played a big role in the site when we didn't have the option to comment on, close, migrate, flag, or edit questions which did not fit the site or required modification to be useful and usable.  As it is, question votes are not much more than a popularity contest, and a lot of bandwidth is taken up on Meta regarding question votes.  Notably:        In most cases a downvote is being given where a good edit should be used instead, or a comment indicating that the question user needs to provide more information.  People are also downvoting in the case of duplicates (or suspected duplicates) when they don't want to do the work of finding the duplicate.  There is no need to downvote to 'alert' other users that a question isn't worth spending time on - if it's bad enough that it can't be fixed, and so bad that you want to be sure others avoid it then it's not worth keeping open.  These are all situations where the person downvoting should be taking a different action.  , and several questions have thrown ideas at how to increase question upvoting artificially, and a  was even implemented to encourage this behavior.  Given all this, I am now convinced that voting on questions is an unnecessary distraction.  Voting no longer provides any useful information about a question, and there are more than adequate means of fixing or removing questions that need work.  Voting makes more sense for sites like Meta where questions aren't really questions, but suggestions and discussions.  For purely Q/A sites such as SO, SF, SU, the voting is superfluous.  The only two possible positive things voting now provides are:   A way for users at lower rep levels to have a voice when they are unable to perform many of the other functions that are needed to fix a question (I contend this is useless, but perhaps they need some sort of outlet) A 'hook' to get new users into the reputation game (which fails frequently because questions aren't getting upvotes, especially questions from new users)   If that is truly the case, then we should consider removing question voting altogether, or removing the effect of question votes on reputation.   Am I wrong? What obvious and explicitly important role does question voting play in our community? "as much as you and I" vs. "as much as you and me" The difference between two periodic functions converges to zero, is this two functions identical? If $f(x)$ and $g(x)$ are two periodic functions, that is, $f(x+T_1)=f(x)$ and $g(x+T_2)=g(x)$ for every $x \in \Bbb R$. Now that $\displaystyle\lim_{x\to\infty}(f(x)-g(x))=0$.  Conjecture: $f(x) \equiv g(x)$.
