Onomatopoeia for disgust
What's a common interjection for the reaction to something creepy and disgusting (like some insects or spooky places, etc.)?
Why does the version of Java verified by Oracle differ from the version shown at the command line? Questions  Why do versions differ?   Should we trust Oracle's verification routine?

What are you going to do at/on/for/over the weekend/s?    We are going to Paris on/at/for/over the weekend/s.   Are you going to stay here for/at/on/over the weekend/s?      Which preposition do American English speakers use — at, on, for, over? Is it possible for a foreigner to drive through (mainland) China in a foreign-registered car? Is it possible to drive through mainland China, for example for transit from Kazakhstan to Vietnam, as a non-Chinese citizen, in an own car/van/truck?  This is about an European Union citizen, trying to make a tourist trip overland by car from the EU to Vietnam. This is about a special (equipped with sleeping, cooking and other facilities) vehicle, that the owner intends to keep and use in Vietnam, so buying/renting a vehicle inside China and selling it before leaving is not an option - the question is about driving a specific vehicle the owner already has in the EU to Vietnam. getting new licence plates is OK, as long as it is allowed to put back the old ones when the vehicle gets back to the EU.  What legal issues are there with getting in an own car over China, and how to overcome them?  Is it possible to drive a car with EU licence plates through China, or would one have to get something like temporary Chinese plates? Is an EU driving licence valid? Are there any customs issues one has to know about, and how long one can keep a foreign motor vehicle in China without having to pay import taxes on it? Sum of two co-prime integers I need some help in a proof: Prove that for any integer $n&gt;6$ can be written as a sum of two co-prime integers $a,b$ s.t. $\gcd(a,b)=1$.  I tried to go around with "Dirichlet's theorem on arithmetic progressions" but didn't had any luck to come to an actual proof. I mainly used arithmetic progression of $4$, $(4n,4n+1,4n+2,4n+3)$, but got not much, only to the extent of specific examples and even than sometimes $a,b$ weren't always co-prime (and $n$ was also playing a role so it wasn't $a+b$ it was $an+b$).  I would appriciate it a lot if someone could give a hand here. How to avoid duplicating assigned materials when duplicating a mesh? how can I prevent Blender 2.8 from duplicating materials every time (?) I duplicate a mesh. Why does stdafx.h work the way it does? As usual, when my brain's messing with something I can't figure out myself, I come to you guys for help :)  This time I've been wondering why stdafx.h works the way it does? To my understanding it does 2 things:   Includes standard headers which we might (?) use and which are rarely changed Work as a compiler-bookmark for when code is no longer precompiled.   Now, these 2 things seems like two very different tasks to me, and I wonder why they didn't do two seperate steps to take care of them? To me it seems reasonable to have a #pragma-command do the bookmarking stuff and to optionally have a header-file a long the lines of windows.h to do the including of often-used headers... Which brings me to my next point: Why are we forced to include often-used headers through stdafx.h? Personally, I'm not aware of any often used headers I use that I'm not already doing my own includes for - but maybe these headers are necessary for .dll generation?

Is the only option for them to go around the western end (since it stops at the Shadow Tower)? Is this clarified in the book? Are other methods mentioned in subsequent books? is $\sqrt{x}$ always positive? What is a "closed" or "duplicate" question? History substitution fails when implemented in shell script The below command works in command line  rsync -avh -r /Source/09_03_2016/ /Destination/ echo $(basename !:3)      Output 09_03_2016   But when I do this in shell script it does not work  #! /bin/bash  /usr/bin/rsync -avh -r /Source/09_03_2016 /Destination/; echo $(basename !:3)      Output  !:3 When to use "If I was" vs. "If I were"? `lmodern` package reduces the size of automatically sized delimiters in math mode Can I get SSD rw performance while keeing data security if I combine SSD & HDD in btrfs RAID1 I have 2 storage devices; classical slow HDD (750GB, /dev/sda) and faster SSD (128GB, /dev/sdb). Currently I have installed Ubuntu &amp; Mint on same btrfs partition on SSD (/dev/sdb5). My btrfs pool consists of /dev/sdb5.  What I want to achieve is data replication on HDD while keeping SSD performance: Something like this:  For read case it would be ideal for procedure to go like this:   read from SSD check checksum if it verifies.. awesome, give me the data if not, fetch data from HDD and perform error correction through duplicate data   I'd manually run (some tool I'm not sure which one... btrfs check --repair perhaps?) every month or so to check HDD checksums and correct them via SSD data against bitrot.  For write case:   write to SSD sync to HDD when write requirements are low, thus not slowing down the system.   Is this possible and how would I do it?  Bottom line is, I like btrfs and would like it to duplicate data across HDD &amp; SSD drive automatically while keeping SSD excellent performance.   Using SSD as write cache is not an option since it's missing data duplication and security. I would like to configure my Ubuntu 12.04 server to synchronize its clock with a specific NTP server. Where to set this up? How can we improve the inconsistent tagging of the questions relating to the recent uproar and associated issues? Question description  There are many questions (~250 in the last five weeks) relating to      sometimes they are about licensing, legal issues, , , , etc.  These questions relate to the same growing polarization between community and Stack&nbsp;Exchange staff. But, it is not easy to search or filter them because the tags are not uniform for those questions, they do not have the same tags.  Could we group all these posts together by some common tag (new or not)? (in addition, maybe we should create less of these questions, they tend to become noise now, water down the core message, and it is ).    Relevance  Overview of current tags (aside from the discussion tag) for the first ten  (           ) questions relating to  (ordered by relevance)                              1   2   3   4   5   6   7   8   9   10     moderators              x           x   x   x     community               x           x   x     etiquette                   x     users                       x     company                     x     moderation                      x     code-of-conduct                     x       x       x     deleted-questions                               x     legal                                                   x   These tags are obviously not the same while it is arguably the same topic (it is even for the same, specific, search term) .  Instead of using multiple searches one might wish to control tracking these question by adding some single relevant tag to watched tags or ignore tags. But, this is difficult when they do not use the same tag. And in the case of ignoring one might ignore too much when the tag is not specific.  Another indicator that these posts need consistent tagging is the fact that there exist highly upvoted answers that function as an archive for these questions (see  and ). But it is only a hack/workaround for the absence of a common tag; they are not an optimal solution.    Why now?  In an older question () it was suggested to create a specific tag. That was rejected at that point. But, now we are several weeks, and many many questions, further. The situation is more escalated than what might have foreseen at that point. The overview becomes a mess and something needs to be done.  See the bump in the image below which indicates that something is 'going on' and it entails a large fraction of the current post. (obtained from ) $Path hijacked by PacletManager? Simple property of a valuation on a field How to place a float at the top of a floats-only page? Infiniteness of non-twin primes. Well, we all know the twin prime conjecture. There are infinitely many primes $p$, such that $p+2$ is also prime. Well, I actually got asked in a discrete mathematics course, to prove that there are infinitely many primes $p$ such that $p + 2$ is NOT prime. The full prophecy by Trelawney, the part my question is about in bold:     "The one with the power to vanquish the Dark Lord approaches ... born to those who  have thrice defied him, born as the seventh month dies ... and the Dark Lord will mark him as his equal, but he will have power the Dark Lord knows not ... and either must die at the hand of the other for neither can live while the other survives ... the one with the power to vanquish the Dark Lord will be born as the seventh month dies ..."    – Sybill Trelawney (to Dumbledore)    I am interpreting      for neither can live while the other survives   as: Harry can't live while Voldemort survives and vice versa. But why? It clearly worked until the end of book 7. One could argue with Dumbledore's thery of the self-fulfilling prophecy. But clearly Voldemort was smart enough to see that there was no mechanism that would kill him just because Harry stayed alive.    and either must die at the hand of the other    Again: Why? If somebody else destroyed all Horcruxes and then killed Harry, Voldemort would be just as vulnerable and could be killed by anyone. On the other hand, Harry could have been killed by anyone - his mum's protection transferred to Voldemort by Harry's blood was only helping against Voldemort.  I guess that I am interpreting this part of the prophecy in the wrong way or maybe there is an alternate, less obvious and more tricky one. So my question is: What exactly does the highlighted part of Trelawney's prophecy state?
