Do people down vote questions simply because the question is a duplicate of another question?  I've noticed that this seems to be the case as a lot of duplicate questions are always in the negative.   I can understand why people would do this if the title is very similar to the duplicate question, but a lot of the time even if the asker tries to find similar questions it can be difficult if the title is phrased differently.  In the case that the title is different to the duplicated question, are people downvoting the duplicate question solely because it's a duplicate, or is it because of poor grammer, etc.?   I think that it is a problem that (if) this is happening because it leads the asker to delete their question, which in turn makes it difficult to find the original question with the answer, leading to more duplicate questions.

But if I find a correct question, closed (or not yet) as duplicate, is downvote a correct behavior for Stack&nbsp;Overflow policy?
After deleting all nodes, how do I reset the node ID to start from 1 again? I generated tons of dummy content for testing, and then deleted them all.  As nid is auto-increment, newly created node will have a nid of last created nid +1.  How can I make nid start from 1 again? Combine Two SQL queries in one statement How to search questions with only one specific tag? I can search question with target using [target] but the result questions also include question tagged with other tags.   How to get the question with only one specific tag? I've recently started playing Minecraft, and I only have a little experience with enemies (I've been playing with the peaceful setting so I can figure out what the heck I'm doing).  When I did play some survival mode, I happened to be at the top of a pretty large cliff when night hit, and this seemed to protect me - the baddies just piled up at the bottom of the cliff.  However, it seems like this probably only worked due to pathing flukes.  The terrain behind me was pretty easy going, so I suspect if enemies spawned in the right areas, they could still come up and visit.  That said, how can I set up a quick protective shelter for the first night or two?  The days don't seem to last very long, so I don't expect I would be able to generate a lot of high-end materials, tools, etc. to work with.  Also, the zombies caught fire nicely when the sun came up, but there were still some spiders and some other things (creepers? - they were explosive) that didn't go away at daybreak.  Do I need multiple exits for my shelter or some other way to avoid running into all the enemies outside the front door that have accumulated overnight? What is the best way to unit test a method that calls into multiple methods, for example:  modify(string value) {     if(value.Length &gt; 5)  replaceit(value);      else changeit(value); }   This pseudo code has a modify method that (currently) calls either replaceit() or changeit(). I have already wrote tests for replaceit and changeit, so writing a new test for modify will be 99% the same set of code.  I need to test it thought because it may change in the future.    So do I copy paste the existing test code?  Move the test code to a common function?  Any other ideas?  I'm not sure of the best practice here. How to transit through Delhi without a visa? I have read a lot on this subject on the Lonely Planet forum and it looks like the staff on ground can transfer your bags through the Delhi airport if you have a connecting flight without you having to go out to check them in again and therefore needing a visa. I refer of course to the situation when you go with 2 different airlines, because otherwise the luggage is transfered automatically.  I posted a  and mentioned it briefly there, however I think this subject deserves a separate question and a detailed answer.  Does it depend on the type on an airline? I have read that Jet is no problem, what about AirIndia and IndiGo? And what about the incoming flight to Delhi from Europe or USA, do they all can hand over you luggage to the Indian airlines and pick it up again on the way home? Do you have to contact them before and explain your situation? Or check in your luggage directly to your desired destination? Minecraft Empty Chests Command Block I am using the following Command to spawn a new chest at the given coordinates with stuff in it at each new round:  /setblock 264 4 997 minecraft:chest 0 replace {Items:[{id:274,Count:1,Slot:0},{id:275,Count:1,Slot:1}]}   The problem with that is that when replacing the old chest all the stuff in the old chest is thrown out. And that's pretty much not what I want. I need to find a way to replace a chest which might have stuff in it without throwing those things out.  Someone else said I should replace the given position for one tick with lava, which I tried. Works in 90% of the tries (in the other 10% the items from the chest are thrown to far away - out of the spawned lava block), but the problem with that is that I can't use it in wooden areas because it might burn everything down.  So what can I do to fix that problem, because otherwise my custom made Pv.P map is not gonna work?  Thanks very much! Word for romantic partner you are living with but not married to How to retain HTML5 Attributes on Markup I have a page with certain html markup and element attributes as shown in the snippit below:  &lt;ul class="accordion" data-accordion=""&gt;  When I edit the page as a user with the WP Administrator Role the &lt;ul&gt; remains intact upon page update. Perfect.  Yet when a user with WP Editor Role edits the page, the ul tag saves as follows:  &lt;ul class="accordion"&gt;  Notice the data-accordion attribute is removed.  How can I get WordPress to retain markup tag attributes for users with the Editor role? Suppose a cleric casts Zone of Truth on a captured enemy. Unbeknownst to them, the enemy is a rakshasa. Zone of Truth says (PHB, p. 289):     You know whether each creature succeeds or fails on its saving throw.   But (MM, p. 257):     The rakshasa is immune to spells of 6th level or lower unless it wishes to be affected.   Assuming the rakshasa doesn't wish to be affected by the Zone of Truth spell, does the caster know this?  More generally, does a caster know when targets are unaffected by a spell they have cast, either because they have made saving throws, or because they are outright immune to the spell or its effects (e.g., casting Ray of Sickness on a shadow demon, which is immune to poison damage and the poisoned condition)? How to grep for text in a file and display the paragraph that has the text? Which one is correct: "Do you wake at seven?" or "Do you wake up at seven?" Someone said to me that the first one is the correct answer, because you use "wake up" to ask someone to stop sleeping. But I think the first one does not sound natural. Stopping to eat is tedious, is there any way to automate the process? While I've managed to optimize and automate almost everything, constantly having to stop and eat is annoying (I run around a lot, so I get hungry quickly). Is there any device or tool that will keep me well fed at all times without having to stop and feed? Multivariate polynomial with no mixed terms Exercise $7$, page 51 from Hungerford's book Algebra.     Show that $N=\{(1),(12)(34), (13)(24),(14)(23)\}$ is a normal subgroup   of $S_{4}$ contained in $A_{4}$ such that $S_{4}/N\cong S_{3}$ and   $A_{4}/N\cong \mathbb{Z}_{3}$.   I solved the question after many calculations. I would like to know if is possible to define an epimorphism $\varphi$ from $S_{4}$ to $S_{3}$ such that $N=\ker(\varphi)$.  Thanks for your kindly help. How do I calculate the CRC32 (Cyclic Redundancy Checksum) of a string in .NET? Under what circumstances will a passive HDMI-to-VGA adapter work? I have bought a no-brand, passive HDMI Male to VGA Female adapter, to link up a PC with a more dated monitor. It did not work.  After doing some reading, I have learned that buying such an adapter is often discouraged because in many cases it will not convert the signal from Digital to Analog, or the Motherboard/CPU on a specific computer might not be compatible with that particular adapter.   So my question is: seeing how there are so many of these passive adapters on the market, are there circumstances under which they actually do suffice to connect an HDMI output to a VGA input? Or are they generally just a rip-off?  Example of the kind of adapter I bought: What is butterfly lighting, and when do I use it? I often hear the term 'Butterfly Lighting' used when discussing high-fashion and glamor photography. How do I set up Butterfly Lighting, and when do I use it?

Unable to set DYLD_FALLBACK_LIBRARY_PATH in shell on OSX 10.11.1 In shell scripts used for unit testing with dynamic libraries in a directory other than the typical @rpath, I have previously been able to set DYLD_FALLBACK_LIBRARY_PATH to set the directory containing the libraries. Under 10.11.1, bash seems to ignore attempts to set this environment variable:  $ sh -x testscript.sh + DYLD_FALLBACK_LIBRARY_PATH=/Users/something/testinglibs + export DYLD_FALLBACK_LIBRARY_PATH + exec printenv   and DYLD_FALLBACK_LIBRARY_PATH is not present in printenv's output.  Is this a security-related hack in 10.11's shell? I haven't been able to find this change documented in man pages or online.
