How to determine equality for two JavaScript objects?
What does the origami represent in Blade Runner? Throughout Blade Runner we see Gaff (Edward James Olmos) making origami figures at various points in the movie. He makes a chicken, matchstick men and at the end of the film there is a unicorn waiting outside Deckard's apartment.    There is a   of  out there regarding the unicorn in particular, and how it indicates that Deckard is a replicant. I think an answer regarding the use of origami in general will be interesting new ground to cover.  Why origami? What does the origami represent in Blade Runner? Applying an ellipsis to multiline text Non in front of hyphenated adjective If one wishes to add "non" in front of a hyphenated adjective, should one add a hyphen after "non?" How do I run a command before or after every command written in the console? How did Google find my unlinked newly created pages? I am building a new site, but creating the content using a subdirectory on an existing site. I have never posted a link to this subdirectory anywhere, yet searching Google reveals that Google has found these pages on my site and indexed them.  Further, I updated the site with a robots.txt file that WMT reports as being read, and testing the blocked pages using the WMT test tool indicates that the pages will not be indexed. Apparently this does not remove the pages from existing results, though I submitted a request to do so.  How did Google find these pages to begin with? Is it because I used a common subdirectory name and Google guesses at common subdirectories? CodeIgniter/PHP Active Record won't increment an integer What does "No bootable medium found" mean in VirtualBox? Let $L$ and $R$ be $n \times n$ matrices. I am trying to solve the following minimization problem  $$ L^{k+1} := \arg \min_{L} \lambda \|L\|_{\ast} + \frac{1}{2\mu}\|L-R^{k}\|_{F}^{2} $$ $$ \mbox{s.t.}\ L \succeq 0 $$  where $\|\cdot\|_{\ast}$ and $\|\cdot\|_{F}$ denote the nuclear and Frobenius norms, respectively. Also, $k$ expresses the $k$th iteration when solving an optimization problem successively.  I don't know how to solve this problem. Would you tell me the way? $k[x]/(x^n)$ module with finite free resolution is free steam fatal error "steam needs to be online to update, but was set to offline movies." I tried re-installing  it but it simply keeps giving me this error in a little window. When I close it, an identical error pops up some 3 seconds later without any new provocation. How to find the list of all available packages along with the lastest version number available in the repositories? I want to list all the packages(installed or not installed) along with the latest version number available in the repositories.  For example:  The output of apt-cache policy chromium-browser shows like below  $ apt-cache policy chromium-browser chromium-browser:   Installed: (none)   Candidate: 34.0.1847.116-0ubuntu2   Version table:      34.0.1847.116-0ubuntu2 0         500 http://ftp.cuhk.edu.hk/pub/Linux/ubuntu/ trusty/universe amd64 Packages   So the latest version of chromium-browser package available in the repository is 34.0.1847.116-0ubuntu2. Like that, i want to list the version number along with the package names that are available in repositories. And all i want to do this through command-line.  I want the output to be like this,  chromium-browser 34.0.1847.116-0ubuntu2 xxxxxxxxxxxxxx   yyyyyyyyyyy ............     ............ The responsiveness is really bad on a newly installed Ubuntu 14.04 LTS.  Here's the specs of my laptop:  Quadcore Intel i7-4600U CPU @ 2.10GHz 12GB Ram 1TB Samsung EVO SSD   And when gradle is compiling, my entire system slows to a crawl, videos begin stuttering, browser scrolling lags... etc.  The same goes when a page refresh occurs in another window in Chrome, and while it refreshes, the HTML5 video in another tab begins stuttering.  How can I fix this?  Here are some logs:  $ vmstat -a 1 5 -   $ iostat -x 1 5 -   $ top -b - The review system suggested something was probably spam, what should I do when I see this? While reviewing suggested edits and first posts by new users today, the review system did something new - an alert appeared that suggested that what I was reviewing was probably spam, and prompted me to take a careful look at it.  Should I be doing anything differently than I otherwise do while reviewing when I see this? Additionally, are my actions contributing to helping the spam prevention systems learn? Sharepoint REST API - Using caml query and select/expand to get lookup data It looks like we'll be adding  support to Stack Overflow. This is necessary to prevent bots, spammers, and other malicious scripted activity. We only want human beings to post or edit things here!  We'll be using a JavaScript (jQuery) CAPTCHA as a first line of defense:    The advantage of this approach is that, for most people, the CAPTCHA won't ever be visible!  However, for people with JavaScript disabled, we still need a fallback and this is where it gets tricky.  I have written a  which we can re-use.    However, I'd prefer to go with something textual to avoid the overhead of creating all these images on the server with each request.  I've seen things like..   ASCII text captcha: \/\/(_)\/\/ math puzzles: what is 7 minus 3 times 2? trivia questions: what tastes better, a toad or a popsicle?   Maybe I'm just tilting at windmills here, but I'd like to have a less resource intensive, non-image based &lt;noscript&gt; compatible CAPTCHA if possible.  Ideas? Did I "get" (or "take") my degree "from" (or "in") the University of Somewhere? I would like to know what is the preferred way to indicate that I took a degree in some subject while also naming the place where I obtained the degree from:   I got my master's degree from the University of Somewhere; I got my master's degree in the University of Somewhere; I took my master's degree in the University of Somewhere.   I would say that "in" is more suitable to mention the particular subject (a degree in maths, for instance) than to indicate the place, but I still have doubts.  By the way, is it a "master's degree" or a "Master's degree"? T-SQL: Selecting Column Based on MAX(Other Column) Why are SMD LEDs shipped in a sealed bag containing desiccant? I had a selection of 0805 LEDs in my last Mouser order and was a bit surprised to discover they arrived in heat-sealed (rather than folded and taped with sticker) bags containing a desiccant bag and some sort of litmus-esque paper indicator saying something about baking them if the dots on it went pink (instead of blue).    A quantity of through-hole LEDs I had in the same order just came in the regular ESD-protective bag, folded over with a sticker.  What's up with SMD LEDs that they work so hard to keep them dry? Surely their dryness can't be assured once they're installed. Does it have to do with their solderability or something? Why would that be different than other SMD parts? I accidentally unset all the directories of $PATH while trying to add a new one in ~/.bashrc. I opened a new terminal window as I was editing and now $PATH is empty. I'm worried if I boot from another drive to find the $PATH I won't be able to boot into this drive again.  Basically, what is the default result of echo $PATH? How do I close a connection early? I'm attempting to do an AJAX call (via JQuery) that will initiate a fairly long process. I'd like the script to simply send a response indicating that the process has started, but JQuery won't return the response until the PHP script is done running.  I've tried this with a "close" header (below), and also with output buffering; neither seems to work. Any guesses? or is this something I need to do in JQuery?  &lt;?php  echo( "We'll email you as soon as this is done." );  header( "Connection: Close" );  // do some stuff that will take a while  mail( 'dude@thatplace.com', "okay I'm done", 'Yup, all done.' );  ?&gt;
