The  (Xanathar's Guide to Everything, p. 19-20) gets the Circle of Mortality feature at 1st level, part of which states:     In addition, you learn the  cantrip, which doesn’t count against the number of cleric cantrips you know. For you, it has a range of 30 feet, and you can cast it as a bonus action.   This wording seems to imply the option, rather than necessity, to cast it as a bonus action. Am I correct in assuming this? Can I still cast it as an action and have my bonus action available?
I get that some spells are "especially swift" to cast and thus have a casting time of "Bonus Action". But is there any reason I couldn't cast such a spell as my Action?   Does it make a difference if the idea is for the one spell to be cast all by itself on a turn or if the desire is to use another Bonus Action (possibly a spell) on the same turn?
Take the following gedankenexperiment in which two astronauts meet each other again and again in a perfectly symmetrical setting - a hyperspherical (3-manifold) universe in which the 3 dimensions are curved into the 4. dimension so that they can travel without acceleration in straight opposite directions and yet meet each other time after time.  On the one hand this situation is perfectly symmetrical - even in terms of homotopy and winding number. On the other hand the Lorentz invariance should break down according to , so that one frame is preferred - but which one?  So the question is: Who will be older? And why?  And even if there is one prefered inertial frame - the frame of the other astronaut should be identical with respect to all relevant parameters so that both get older at the same rate. Which again seems to be a violation of SRT in which the other twin seems to be getting older faster/slower...  How should one find out what the preferred frame is when everything is symmetrical - even in terms of GRT?  And if we are back to a situation with a preferred frame: what is the difference to the classical Galilean transform? Don't we get all the problems back that seemed to be solved by RT - e.g. the speed limit of light, because if there was a preferred frame you should be allowed to classically add velocities and therefore also get speeds bigger than c ?!? (I know  is only a local theory but I don't understand why the global preferred frame should not 'override' the local one).  Could anyone please enlighten me (please in a not too technical way because otherwise I wouldn't understand!)  EDIT Because there are still things that are unclear to me I posted a follow-up question: Does mass distribution/center of mass affect free fall? An everyday is example would be cars. If you were to drop a car, not taking air resistance into account, would a front-heavy car tumble forward as it fell? And a car with a perfect 50/50 front/rear weight distribution fall straight? Does mass distribution/center of mass affect free fall? Or would they both fall straight down without tumbling? Can you explain why please? $\limsup$ and cluster points Let $(x_n)$ be a sequence in $\mathbb R$. We call $y$ a cluster point of $(x_n)$ iff for every neighborhood $N$ of $y$ there are infinitely many $n$ such that $x_n \in N$. Let $C$ denote the set of cluster points of $(x_n)$.   By definition, $\limsup_{n \to \infty} x_n = \inf_n \sup_{k \geq n} x_k$.  Can you show me how to prove $\limsup_n x_n = \sup C$? Thanks. I would like to configure my Ubuntu 12.04 server to synchronize its clock with a specific NTP server. Where to set this up? No field properly between $\mathbb Q$ and $E$ iff $G(K/\mathbb Q) \cong A_4$ or $S_4$ There is no continuous injective function $f:\mathbb{R}^n\longrightarrow\mathbb{R}^m$ I have the following question, more general that   Let $U\subset\mathbb{R}^n$ be a domain. If $f:U\longrightarrow\mathbb{R}^m$  ($m&lt; n$) is a continuous function, how to prove that $f$ is not injective.  Any hint would be appreciated. How can I install updates and shut down from the command line? I know that there is a simple way to shutdown the computer in command prompt, but is it possible to do system updates and then shutdown the computer in command prompt?   For example, when Vista needs to install updates, it will let me install them and shut down by clicking the Shut Down button (while relegating the normal shut down button into the menu). So is there a command to do this in command prompt? How to delete all events on many dates all at once but not the whole Calendar in Google Calendar? How to delete all events on many dates all at once but not the whole Calendar in Google Calendar? I tried to click on a date that got an event to delete and dragged my mouse to 2 days after that date, but then I always see "create an Event". I thought I could press backspace or delete to delete all those events.  What I did so far = deleting event one by one :( Can there be an option to allocate rep from any site account for offering a bounty? I think it would be useful if we had an option when deciding to open a bounty on a question that we could choose to allocate rep from one site even though the bounty is being offered on another site.  For instance I would like to use my rep from SO for putting a bounty on a question that resides on SF. I don't have enough rep on SF to make it enticing. So when you click on "start a bounty" you get sliders for each site that you can pull your rep from, maybe make it where you need to burn up all your rep for the site that your asking the question on and then allocate more rep from other ones, if you have it.  thanks devinb for clearing up my question with your comments! " transfer rep INTO a bounty. But you can't transfer rep across accounts. So, the rep you'd 'lose' from SO would never actually go into your SF account, it would go straight onto a bounty on whatever question." – devinb Show $1/(1+ x^2)$ is uniformly continuous on $\Bbb R$. Are common cryptographic hashes bijective when hashing a single block of the same size as the output? Redirect all requests to HTTPS, except for one subdirectory Why directory with large amounts of entries does not shrink in size after entries are removed? Close vote notice: While the linked duplicate asks same question, the comments and the only answer do not provide an answer which draws from authoritative source. The , does in fact provide the answer I've been seeking. Thus the proposed duplicate isn't helpful, however Thomas's answer here is proper.  According to the  and personal account , directories that have large amount of entries get to a size over 4096 bytes (which can be seen with ls -l output), but once the entries are removed - the number never goes down.   The question is "why" ? Is it due to how ext4 filesystem configured to retain directory metadata ? Obviously removing the directory and recreating it isn't a solution, since it deletes original inode and creates a new one. What can be done to decrease the number manually ? How do I show that if there are functions $f,g$ such that$$ f(g(x)+g(y))=bx+cy $$holds for all $b,c\in\mathbb{R}$, then we necessarily have $b=c$? Is this even true? It seems so, but I'm just not sure how to explain it in detail and using theory from functional equations. Any ideas?  Extra: In addition, I'd like to prove that there are no pair of functions $f,g$ such that$$ y^2+z^2=f(x,g(y-x)+g(z-x)). $$ Any ideas on how to prove this? Plus, does anyone know some literature regarding this type of problems? Will i be granted ESTA after getting rejected thrice on different nationality? I had applied for B1/B2 on my previous nationality but it got rejected Thrice.  I had planned on visiting my mother as she lives there. my last refusal was 3 years back. Now i have gained an European nationality and I am thinking of applying for ESTA so I can visit my mother. I have doubts if it will be accepted because I'll have to disclose about my previous refusals.  What should I do? because if I don't disclose my previous refusals I fear I might be rejected permanently. I configured a journey in Marketing Cloud where i sent an email. My requirement is adding BCC email addresses to this email, but I noticed that we can only add valid email addresses. Could you confirm me that is not possible to add BCC /CC Address using personalization strings or Ampscript functions (e.g. Lookup) inside the Journey Email's settings? .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])? Assuming I have an ArrayList  ArrayList&lt;MyClass&gt; myList;   And I want to call toArray, is there a performance reason to use  MyClass[] arr = myList.toArray(new MyClass[myList.size()]);   over  MyClass[] arr = myList.toArray(new MyClass[0]);   ?  I prefer the second style, since it's less verbose, and I assumed that the compiler will make sure the empty array doesn't really get created, but I've been wondering if that's true.  Of course, in 99% of the cases it doesn't make a difference one way or the other, but I'd like to keep a consistent style between my normal code and my optimized inner loops...

Mavericks unusually high RAM usage I thought Mavericks was suppose to utilize RAM memory better, thus run smoother.  Running ML on Mac mini 2012, with 16GB RAM...always running smoothly even with over a dozen apps running.  Now, after installing Mavericks, my Mac is SLOW, eating up RAM like crazy! Looking over usage, of the 16GB of installed memory...on average it uses 10-14 GB RAM when barely running a few apps!!!   There is this kernel_task that is always running with over 1GB of RAM and most apps are not taking that much RAM, so what is using up all my RAM?! File cache? It shows very high in that new description, with about 1/3 of my total RAM
