Bootstrap: Slide only one image among the multiple images in an item of the carousel
Twitter Bootstrap - multiple image (thumbnail) carousel - move thumbnails one at a time
I was just thinking that maybe if we have more Stack&nbsp;Exchange websites then each person would be a member of more different sites on average. Since the time a person can spend online on average is limited it means he will be spending less time on each website. But would this affect the quality of these websites? I'm not talking only about the quality answers given but also the number of answers given, the promptness. Won't these things go down?  I think that the rate of questions won't go down much because you need to know what you need to know. However, the average time a person spends browsing through these websites (and chances upon a question he can answer) would decrease. So are we creating too many different Stack&nbsp;Exchange sites? Move the period outside the quotes on the site-analytics page If you don’t have 25k reputation, the  contains a stub text:        As you can see on the image, the dot should be moved outside the quotes. Also, on ruSO we need to  from “” to «», but this is not possible via Transifex, because there is no full sentence available to translate. A very compact list in Beamer I would like to make a very compact list (e.g., itemize) in Beamer.  has been asked for an article-type document class; the answer uses the enumitem package, known to be .  My question is: How do I make the same compact list in the Beamer document class? As in the above linked question, I would like the list to have   No whitespace before list No whitespace after list No whitespace between lines Less indent before the bullet points Photoshop "Export > Export As" or "Export > Save For Web" in size 600px + auto suffix in filename I have looked at other questions on this site (e.g. "why does space expansion affect matter") but can't find the answer I am looking for.  So here is my question: One often hears talk of space expanding when we talk about the speed of galaxies relative to ours. Why, if space is expanding, does matter not also expand? If a circle is drawn on balloon (2d plane), and the balloon expands, then the circle also expands. If matter is an object with 3 spatial dimensions, then when those 3 dimensions expand, so should the object.  If that was the case, we wouldn't see the universe as expanding at all, because we would be expanding (spatially) with it.  I have a few potential answers for this, which raise their own problems:   Fundamental particles are 'point sized' objects. They cannot expand because they do not have spatial dimension to begin with. The problem with this is that while the particles would not expand, the space between them would, leading to a point where the 3 non-gravity forces would no longer hold matter together due to distance Fundamental particles are curled up in additional dimensions a la string theory. These dimensions are not expanding. Same problems as 1, with the added problem of being a bit unsatisfying. The answer seems to be (from Marek in the previous question) that the gravitational force is so much weaker than the other forces that large (macro) objects move apart, but small (micro) objects stay together. However, this simple explanation seems to imply that expansion of space is a 'force' that can be overcome by a greater one. That doesn't sound right to me. Remove specific duplicates (all but latest) When removing duplicate rows, using the below query from  tutorial, how would I go about forcing which of the found duplicates to remove?  DELETE FROM dbo.ATTENDANCE      WHERE AUTOID NOT IN (SELECT MIN(AUTOID) _ FROM dbo.ATTENDANCE      GROUP BY EMPLOYEE_ID,ATTENDANCE_DATE)    And this works great. The reason why I am using this one is because the only unique id available is one in the IDENTITY column. And to determine if there are duplicate rows I have to look at a combination of multiple columns.    But if I have a set of duplicate rows how do I / how does SQL Server decide which to remove? And how would I force it to remove all but the one with the highest IDENTITY value?  EMPLOYEE_ID     ATTENDANCE_DATE     AUTOID A001            2011-01-01          1 A001            2011-01-01          2   If I would run the query now it happens to remove the second one, with AUTOID 2. But I am trying to remove all but this one (because this is the one latest added). Electric shock - was I stupid, unlucky, or a combination of both? One of the double sockets in our garage needed replacing (damaged after a washing pole hit it) - a pretty trivial job that I'd done before. So I flipped the MCB for the ring main, used a non-contact voltage tester to check nothing was there, and set to work. I disconnected the old socket fine, and was lining the cables up to fit into the new socket when... ow.  My finger bridged the live and earth pins, and suffice to say the live wire was very much alive. Bar a few finger spasms I was fine fortunately, and believe me I realise I was very lucky in that respect (I'm in the UK, so that was 240V.) Before finishing the job I then shut off the entire property's electrics - I was taking no more chances.  Further inspection confirmed two things I immediately suspected at this point - the MCB in the garage (installed before we moved into the house) was shutting off power via the neutral, not the live, and the voltage tester was dodgy (I had tested it on the same socket earlier and it seemed fine, further testing showed it presumably had a loose connection internally and only worked sporadically.) Needless to say it's now in the bin, and an electrician has been called to sort the MCB and check the rest of the house for similar issues.  Unsurprisingly this has shaken me up a bit - I would say I'm a rather safety conscious person, and in this case thought I'd done all the checks properly (including taping over the relevant trip switch to ensure no-one flipped it back on while I was working.) In some ways I can't help feeling I was unlucky that the MCB was wired by a cowboy, in combination with the voltage tester failing in the way that it did, at the time that it did. However, I'm not one to solely blame tools - clearly some, if not most of the blame here lies with myself also.  So in short, what should I have done differently - and was I primarily being stupid, or really quite unlucky? How to disable all caches in safari 11? I am using Safari to develop for a while. One thing I always liked is when you clear the cache, it really does, unlike other browsers I tried in the past. But in previous versions, specially when working in a code in a local testing server, just reloading the page will reload everything from disk. Now I have to use de shortcut command+alt+e to clear before reload or some new CSS won't load, even some http request will return old values. Just reloading the page won't guarantee to show me the last modifications.  I looked at preferences and develop menu but didn't find an option to just don't use any caches at all - the perfect option will be don't use caches when I have the web inspector opened, means I am developing.  Did I miss this option, or there is another way to disable all caches? What's the quickest Schengen consulate to issue a visa in London? How to get ASCII value of string in C# I want to get the ASCII value of characters in a string in C#.  If my string has the value "9quali52ty3", I want an array with the ASCII values of each of the 11 characters.  How can I get ASCII values in C#? How to optimize images to improve pagespeeds / webpage loading times? This is almost a StackOverflow question, however it's completely related to Photoshop and other tools. With every Pagespeed test I do for all my website I get the comment "Optimize images by lossless compressing image X" which often increases my page rank a lot.  I already save EVERY image with 'save for web' with Photoshop, but I was wondering how I could "Optimize images by compressing lossless" even more. As far as I know I'm already doing everything I can.   How can I optimise images to improve my webpage loading speeds? What are the benefits of modeling in one piece, or as separate parts? Closing Etiquette: Why Do Some Answer *and* Close? I've noticed quite a few cases () where people not only vote to close a question, but then also answer said question. At best this is just silly, and at worst it is totally hypocritical and seems almost like rep whoring (since often the closers answers are the only ones that remain to be voted on since no new answers can be given).  If you want to close a question, it makes more sense to simply add a comment if you feel the need to say something. This also leaves the option open for the author of the question to delete it if they want to. If the author realizes they've asked a duplicate, or they want to avoid the onslaught of downvotes that can often accompany a closed question, they should be allowed to delete it. However, if any answers to the question have upvotes, the author can't delete it.  So why do people answer and close? Should we try to crack down on this sort of thing, via either new features, clearly stating it in the FAQs, or just getting the word out through commenting when we see it?  EDIT: Just to clarify, I'm asking this in relation to SO, not MetaSO. Is there a way to enable commenting adobe PDF? Could the universe's antimatter be hiding in black holes? As far as we know almost all the mass in the universe is matter, not antimatter. There are three scenarios:   The universe started off with more matter than antimatter and the small amount of antimatter has mostly been converted to energy via collisions with matter The universe started off with equal amounts of matter and antimatter and some unknown process caused the situation we see today The universe started off with less matter than antimatter and somehow the ratio reversed (I've never heard this discussed as it seems so unlikely)   We reason that mass is matter because if there were large amounts of antimatter they should produce antimatter galaxies, which would give off huge amounts of energy when they interact with matter galaxies. This has never been observed so we conclude that all galaxies, therefore all mass in the universe is matter.  As I understand it there are two main types of black holes, stellar remnants (the collapsed remnants of dead stars with more than two solar masses) and super-massive black holes at the centre of many galaxies, including one thought to be at the centre of our own galaxy.  Stellar black holes are obviously originally composed of matter, for the same reason that all galaxies are composed of matter.  We don't know how super-massive black holes formed. Is there enough mass in them to contain all the antimatter in the universe if matter and antimatter were originally created in equal quantities? I realise this shifts the unknown mechanism from "why was more matter created than antimatter" to "why is antimatter more likely to form super-massive black holes" but is this hypothetical scenario possible? Evaluating $\int_0^{\infty}\frac{\ln(x^2+1)}{x^2+1}dx$ Finding limit of a sequence in product form \begin{equation} \prod_{n=2}^{\infty} \left (1-\frac{2}{n(n+1)}  \right )^2 \end{equation}  I need to find limit for the following product..answer is $\frac{1}{9}$.

What is the formula for Real vs Apparent Depth, when not looking perpendicular to the interface?   I know the formula $$\frac{\text{real depth}}{\text{apparent depth}}=n$$   but I'm not looking for this. Why disable Fast Boot on Windows 8 when having dual booting? I looked up a few grammar-teaching websites (in Chinese language). The website says many people do not use the phrase "A xxx of" correctly because they do not identify the subject of the phrase correctly.   The website says phrases like "A range of; A high percentage of" is singular, while "a number of; a group of; a couple of; a total of" is plural.  Therefore according to the website, the correct sentences should be as follows.     A wide range of courses is available. ("A wide range" is the subject)      A high percentage of peptides that are made of amino acids is present   in the sample. ("A high percentage" is the subject)      A number/ group/ couple of people were killed in the earthquake.("people" is the subject )       A total of 230 employees were laid off. ("employees" is the subject)   I don't get the pattern here. All of this looks (or should I use "look"?) arbitrary to me. In fact I thought this phrase is supposed to be arbitrary and whether the phrase is plural or singular should depend on the the person's own judgment.   How do I identify the correct subject in the "A xxx of" phrase?
