How does animated water work? The spell Shape Water lets a caster animate some water.  While the effect is limited to 'simple shapes', lasts an hour, and acts according to your direction, nearly nothing else about the effect is specified.  I want to know how the animated water option of Shape Water works and what it is capable of, for example:  Anna the Wizard casts Shape Water animating the water in a 5' hole excavated via Mold Earth.  She forms the water into the crude shape of a miniature horse, and attempts to put a miniature saddle on it.  What happens?  Her weasel familiar attempts to mount the water-horse.  What happens?  She casts Find Familiar and changes her weasel familiar into a fish, which attempts to swim in the 'horse'.  What happens?  The 'horse' gallops away.  How fast can it go?  Does the fish go with it?  Anna casts Shape Water a second time on a second hole, this time animating the water into a 20' radius hollow sphere a quarter-inch thick (the volume ).  What happens? Anna climbs to the top of a 20' tall A-frame ladder and mentally directs the sphere to roll over her so that she is at the center.  What happens? Her buddy Bartholemew wants to throw an overripe tomato at her from outside of the sphere (Don't worry, Anna prepared featherfall today).  Does she have cover?  If so how much?  If it is total cover, does that stop Bob from trying to throw the tomato?  Anna then tells the sphere to go knock on the door of Cardamon the Cultist, who lives next door to her in a town 2.5 miles away, and then to find and roll over the unprotected flames she expects Cardamon's kids will have left somewhere in their back yard, and then to track down a copy of the Book of Exalted Deeds and bring it back to her.  How much of this can the sphere do?  Anna dismisses her familiar and then the galloping water-horse before casting Shape Water yet another time, on a third hole, this time forming the water into a comically large mallet.  She has the mallet spin up into the air and then fall down on practice dummy.  Does the practice dummy take any damage?  Is it moved?  Is it wet?  Later, she has the mallet fly around bonking some enemies on the head.  What happens?  In general, this spell (and to a lesser extent Control Flames) is often extremely problematic in games I run or play in, essentially requiring the GM to come up with mountains of rulings as to how the nearly endless uses of animated water constructs work, and what they can and can't do.  The spell clearly lets you make stuff with the water and have it do stuff, but it feels like there must be a whole bunch of rules somewhere I'm missing or something.
What are the limitations on the Shape Water cantrip? I have been having a discussion regarding the Shape Water cantrip from the Elemental Evil Player's Companion. A friend and I are trying to come to an accurate view of how this spell actually functions.   Some example questions:   Must the targeted water be within a 5 foot cube area, or does it need to be of a volume not exceeding 125 cubic feet? If you shape water that is within a 5 foot cube, can the final shape you animate it to extend outside the cube? Can you cause the shaping to affect ice and snow, or only liquid water? Would you be able to carry a globe of water alongside you over distances?   Really, there are two parts:    What can be targeted by the spell? What are the limitations on the 'shape and animate' portion of the spell?   The answer I am looking for, if possible, would use the language of the spell, possibly with precedent from other game text, to clearly define the limitations of this cantrip.
Recently, my answers are showing at the bottom of the page, even though I got good scores on those answers.       How do I change this back? Given Newton's third law, why is there motion at all? Should not all forces even themselves out, so nothing moves at all? When I push a table using my finger, the table applies the same force onto my finger like my finger does on the table just with an opposing direction, nothing happens except that I feel the opposing force. But why can I push a box on a table by applying force ($F=ma$) on one side, obviously outbalancing the force the box has on my finger and at the same time outbalancing the friction the box has on the table? I obviously have the greater mass and acceleration as for example the matchbox on the table and thusly I can move it, but shouldn't the third law prevent that from even happening? Shouldn't the matchbox just accommodate to said force and applying the same force to me in opposing direction?

Now, I'm aware that  svchost runs services and I know how to display the services it runs in Task Manager or Process Explorer ().  Now I know which services are run, but I don't know which service eats the CPU time. I could disable one service after another, but I don't really like doing this (it could break things that are currently in use and I could forget turning the service back on later).  Therefore I'd like to know whether it's possible to instruct Windows to run only one service per svchost the next time I boot my PC. While I might have the slight disadvantage of several processes, I could immediately find out which one it is and it would be a much easier decision of whether or not to stop or restart the service. I have 100 files with 57,816 rows each.I want to do an outer join of these files by merging on basis of the common column.  I am using R programming for this but this is very slow.  fileList &lt;- list.files(, pattern=".txt") pm_list=lapply(fileList, read.table) merged_pm=merge_all(pm_list, by = "gene_short_name")   Is there any quick way to do this in bash? The other method that I can use is SQL but I have to create 100 tables first and then load them up before join,which is not very efficient way to do.  The number of rows are equal in each file, thats why I want to merge  based on common column and can't use cbind from R as the constants in the common column are a bit up and down in different files and not present at same location in each file.Below are two sample files.I want to join based on 'gene_short_name'  gene_short_name FPKM56  MT-TF   0.90 MT-TV   0 MT-RNR1 310.015 MT-TL1  0 MT-TM   0   File 2 is below:  gene_short_name FPKM53  MT-TF   0 MT-TV   0.344 MT-TM   0.10 MT-TL1  0 MT-RNR1 0 MT-ND2  158.332 On the order of elements of $\mathrm{GL}(2,q)$. There's a particular property of the elements of $\mathrm{GL}(2,q)$, the general linear group of $n\times n$ matrices over a finite field of order $q$, that I don't understand.  I know that the order of $\mathrm{GL}(2,q)$ is $(q^2-1)(q^2-q)=q(q+1)(q-1)^2$, since there are $q^2-1$ possible vectors for the first column, excluding the $0$ vector, and $q^2-q$ possible vector for the second column, excluding all multiples of the first.  So the order of any element must divide $q(q+1)(q-1)^2$ by Langrange. However, there is a further detail that      any element of $\mathrm{GL}(2,q)$ must have order dividing $q(q-1)$ or $(q-1)(q+1)$.    Is there a reason why one can narrow down the order to divide one of those smaller factors of $q(q+1)(q-1)^2$? Thanks!

I have the basic 18-55mm lens that came with my camera but I need a next step up that's not too expensive.   What are the most common types of photos shot with either lenses? Or what is each lens best for? Can matter be described as the result of the curvature of space, instead of vice versa? Can matter be described as the result of the curvature of space, rather than the curvature of space being the result of matter, and energy being the cause of the curvature of space? Is my ESTA valid for a second trip? I visited the USA in May this year, on an ESTA which I applied for in April. It was approved and I was allowed entry into the country.    I'm re-visiting again this November for two weeks. Am I able to use the same ESTA again or do I need to re-apply for a new one? I know it says it's valid for two years, but is that valid for every use within those two years, or I have to use it within two years, and once I have visited on that visa, it's invalid? Function pointers, Closures, and Lambda I am just now learning about function pointers and, as I was reading the K&amp;R chapter on the subject, the first thing that hit me was, "Hey, this is kinda like a closure." I knew this assumption is fundamentally wrong somehow and after a search online I didn't find really any analysis of this comparison.  So why are C-style function pointers fundamentally different from closures or lambdas? As far as I can tell it has to do with the fact that the function pointer still points to a defined (named) function as opposed to the practice of anonymously defining the function.  Why is passing a function to a function seen as more powerful in the second case, where it is unnamed, than the first where it is just a normal, everyday function that is being passed?  Please tell me how and why I am wrong to compare the two so closely.  Thanks. Isn't the uncertainty principle just non-fundamental limitations in our current technology that could be removed in a more advanced civilization? From what I understand, the  states that there is a fundamental natural limit to how accurately we can measure velocity and momentum at the same time. It's not a limit on equipment but just a natural phenomenon.  However, isn't this just an observational limit? There is a definite velocity and momentum, we just don't know it. As in, we can only know so much about the universe, but the universe still has definite characteristics.  Considering this, how do a wide range of quantum mechanical phenomena work? For example, quantum tunneling - its based on the fact that the position of the object is indefinite. But the position is definite, we just don't know it definitely. Or the famous light slot experiment? The creation of more light slots due to uncertainty of the photon's positions?  What I am basically asking is why is a limit on the observer, affecting the phenomenon he is observing? Isn't that equivalent to saying  because we haven't seen Star X, it doesn't exist? It's limiting the definition of the universe to the limits of our observation! I've just received a memo which says (effectively)      As more people leave, there will be less people available.

I have a Samsung Galaxy S5 duos with stock Android Marshmallow, and I'm considering encrypting my SD card to prevent access to its contents in case I lose my phone. The main reason of not doing this is that I'm not sure if there's a way to mount an encrypted SD card on Windows (or other desktop OS's)   When I encrypt the SD card on my Samsung Galaxy S5, is it using a known implementation of encryption, or is it something that only works on Android (or perhaps Samsung) phones?   I do not want to use USB connection to my phone to access my SD card, it's terrible. Mounting the SD card is much easier and faster and less annoying.   EDIT: just to clarify, I am NOT talking about adoptable storage. I want a portable encrypted SD card that can both be read on PCs and Android phones (i.e. I want to be able to remove the SD card from my phone, plug it into my PC, provide a password to decrypt and read/write it like any other SD card) Sci Fi action movie where an elite group of people control business through a game they play online While deploying code in vsCode from sandbox to production I get the below error      sf:INVALID_OPERATION: INVALID_OPERATION: testLevel of NoTestRun cannot   be used in production organizations   As per the error, I need to change the value of testLevel but I am not able to find where and how can I change it to RunLocalTests  Could someone please help me to change the value of testLevel in vsCode UK Visa Refusal: Provenance of funds/parking I have applied recently for a general visitor visa to the UK to spend 10 days during Christmas with my British unmarried partner and it has been turned down.   The Entry Clearance Officer stated on his refusal notice the following:     I note that you have never previously travelled to the UK or any country with similar immigration requirements and you therefore do not have a history of travel and compliance to consider.      You have submitted an employment letter to confirm your occupation in KSA but I am required to also assess your personal, domestic and economic circumstances in determining whether you are genuine visitor travelling to the UK for the period and purpose you state.      You claim an income of SAR ........ per month which equal ........ GBP and from the evidence submitted this appears to be your sole source of income.   I note that this monthly income is reflected on your bank statements. However, the bank statement you have presented show a recent large deposit that are in excess of your stated income and inconsistent with the account history. You haven't provided evidence toward the origin of this recent deposit and in the absence of reasonable evidence I am not satisfied that these bank statements accurately reflect your personal circumstances.      In view of the above, I am not satisfied you have demonstrated that your circumstances are as you claim and therefore I am not satisfied that you're travelling to the UK for the period and purpose you stated. 41(i)and(ii).   Its true that I have deposited that sum of money right before I apply and it was a commission I received from work earlier this month.   So, could you please give me your advice on the above as I am planning to apply again soon. and how to avoid my application being refused again? I have just started studying implication in mathematics. So, you'll probably have an idea of where my confusion lies right from the get go.  In the truth table, where $A \implies B$ we obtain this result:  A   B   T/F ___________ T | T | T T | F | F F | T | T F | F | T   Now, my confusion here is regarding why $A\implies B$ given A is false, and B true. The others I understand. The first and last one are obvious, the second one implies, to me anyway, that given A implies B, the truth of B rests upon the truth of A, B is false, A is True, which cannot be, thus not B given A is false.  Now... then, why is B true despite the fact that A is false? Or rather, why is the statement B given not A, True. The truth of B is implied from the truth of A, but A is a false statement. So it's very contradictory that this may be, and in fact, if you go through a real life example, you would find that the third statement seems to be false.  Say $A$ is the statement that it is dark outside, and $B$ the statement that the sun is not on our side of the earth. If it is not dark outside, than stating that the sun is on the other side of the planet must be wrong (in my example i'm going to claim that the sun is the only light source).  Side note:  I just had a thought, if A is false, does that mean you can conclude... mmm, whatever? I mean, B is implied via the truth of A, if A is false, B is NOT implied, but then B could be EITHER true or false, I suppose. Is this correct?  However, would that not mean that A does not imply anything when false. Would that not set the 3rd and 4th statement to be undefined?
