Getting a stack overflow exception when declaring a large array
How to Update Multiple Array Elements in mongodb Need advice on flavoring/sweetening my homebrew cider I've just finished my primary fermentation and have produced a cider that is coming in at 5.2%. I am about to bottle my cider and add some priming sugar to give it a bit of a fizz. I would like to try and flavor some of the ciders with a fruit coulis. am I correct in thinking that the natural sugar in the fruit should give the cider a natural fizz and I don't need to add any sugar? Also, I am a fan of a sweeter cider, I have been advise not to add more than a teaspoon of priming sugar, and to use a sugar substitute at the same stage if i wish to sweeten it. I have purchased Xylitol, I plan on trying a few combinations with the priming sugar/Xylitol &amp; no additive fruit coulis. Does this all sound like it makes sense or am I just going to ruin my cider. Fastest Gun in the West Problem How to find all positive integers $n$ such that $(n-1)!+1$ can be written as $n^k$ for some positive integer $k$? How can I detect when an Exception has been thrown anywhere in my application?  I'm try to auto-magically send myself an email whenever an exception is thrown anywhere in my Java Desktop Application.  I figure this way I can be more proactive.  I know I could just explicitly log and notify myself whenever an exception occurs, but I'd have to do it everywhere and I might(more likely will) miss a couple.  Any suggestions? I thought people would be working on little code projects together, but I don't see them, so here's an easy one:  Code that validates a valid US Zip Code. I know there are ZIP code databases out there, but there are still uses, like web pages, quick validation, and also the fact that zip codes keep getting issued, so you might want to use weak validation.  I wrote a little bit about zip codes in a side project on my wiki/blog:    There is also a new, weird type of zip code.     I can do the javascript code, but it would be interesting to see how many languages we can get here. Remove Indentation for a Single Paragraph Is there a way to remove the indentation at the beginning of a paragraph for a single paragraph.  I know I could do  \setlength{\parindent}{0cm} This is my paragraph.  Blah blah blah. \setlength{\parindent}{default}   Where default is whatever the default indentation is for the document class I am using (part of the problem is that I don't know what this default value is).  I feel as if there should be a better way to accomplish this than by the above method.  I am looking for a solution of the form:  \noindent This is my paragraph.  Blah blah blah.   Is there a way to do this, or will I have to resort to the former method?  If I have to resort to the former method, what is the default indentation value for the amsart document class? switch a theme different per user role I plan to use the member plugin by Justin Tadlock  I wish to know if how could I, on the front side, auto switch to a theme according to a role status.. for example authors would have the site presented using theme 1 while editor would have the site presenter using theme 2  I would rather have 2 different theme rather than conditionals within one theme structure  Thank you in advance Mathoverflow - why so different Show that $2730\mid n^{13}-n,\;\;\forall n\in\mathbb{N}$   I tried, $2730=13\cdot5\cdot7\cdot3\cdot2$  We have $13\mid n^{13}-n$, by Fermat's Little Theorem.  We have $2\mid n^{13}-n$, by if $n$ even then $n^{13}-n$ too is even; if $n$ is odd $n^{13}-n$ is odd.  And the numbers $5$ and $7$, how to proceed? The text of the  spell reads:      A flickering flame appears in your hand. The flame remains there for the duration and harms neither you nor your equipment. The flame sheds bright light in a 10-foot radius and dim light for an additional 10 feet. The spell ends if you dismiss it as an action or if you cast it again.   Emphasis mine. The druid in our party asked our DM if he is able to cast produce flame in a dark cave, then opt not to attack with it, and wield a shield and sword. The goal is to continue emitting light, since he doesn't have the light spell. He claims that since the flame does not harm his equipment, he is able to hold a shield or sword with the fiery hand with no problem.  Is this okay to do RAW, or are we missing something?  This is specifically not asking about casting spells with a sword in hand. He wants to draw his weapon after casting and holding the flames.  Related, but not the same question: , , . Is fractional scaling ( ) available in 18.04 LTS yet? I am waiting until this is available before I install. This is from page 3 of  ().  Copying the relevant segment:     Stirling’s approximation tells us $\sqrt{2\pi n} (n/e)^n \leq n! \leq e^{1/12n} \sqrt{2\pi n} (n/e)^n$. In particular we can use this to say that   $$ {n \choose k} \leq \left(\frac{en}{ k}\right)^k$$   I tried the tactic of combining bounds from $n!$, $k!$ and $(n-k)!$ and it didn't work. How does this bound follow from stirling's approximation? I have a Microsoft XBOX 360 gamepad with the wireless adapter and I was wondering what I would have to install to use them with Ubuntu I do know that when using this on Windows I have to manually install the drivers for the wireless receiver (if that is relevant.) I know this has probably been asked before, but I couldn't find it with Google.   Given   Linux Kernel No configurations that change $HOME bash   Will ~ == $HOME be true? How to encrypt folders (not in Home)? Is there a way to encrypt a folder, which is not in Home (/home/user/) but even in a different partition, so only my user can access/read contained files?  Alternatively, I would like to understand if it is possible to turn a complete ext4 partition into an encrypted volume, which would be mounted at user login.  If possible, I would like to make the change without reinstalling Ubuntu.  My PC has (mount output):  /dev/sda1 on / type ext4 (rw,errors=remount-ro) /dev/sda3 on /home type ext4 (rw) /dev/sda4 on /home/igor/Personale type ext4 (rw)   sda4 is the partition containing folders I would like to protect. What is the difference between "retired out" and "retired not out" in cricket? I was wondering if it is possible to get a link to a rigorous proof that  $$\displaystyle \lim_{n\to\infty} \left(1+\frac {x}{n}\right)^n=\exp x$$ How to compare two float values in ksh?
