Do I always need a capital letter after an exclamation mark or a question mark?  I'm bilingual with french, and, especially in older works, I've often stumbled upon exclamation marks or question marks that don't end a sentence, but merely serve to accentuate a specific part of a sentence. Sometimes they replace a comma, sometimes not.  Is this kind of stuff legal in the english language or not? I haven't seen it in english texts so far, but I have no reason to believe it would only exist in french and not in english.  EDIT: Here are some examples (in french) that  provides:     « Ah ! non ! c'est un peu court, jeune homme ! On pouvait dire… Oh !   Dieu !… bien des choses en somme… »        — Edmond Rostand, Cyrano de Bergerac (I, 4)      « C'est la femme d'un autre ! ô jalousie affreuse ! »        — Victor Hugo, Ruy Blas (II, 3)
May I use a question mark in the middle of a sentence? Examples:  Would you like the drapes to be white? or perhaps something off-white? Would you like the logo to be centered? at the bottom? left off entirely?
What is a concise function that formats a (String) decimal into a currency format in Apex? I'm trying to factorise $$ x^3z - x^3y - y^3z + yz^3 + xy^3 - xz^3 $$ into four linear factors.  By plugging it into WolframAlpha I've learned that it's $$-(x-y)(x-z)(y-z)(x+y+z)$$  My question is: what are the steps involved in factorising the expression? Is there a method I don't know about that I'd have access to with my limited maths?  Really appreciate any help! Entity Framework and SQL Server View We should make books of our best content! And that's a good idea!  We have a lot of high quality content here, certainly enough for a small book.   I'm not saying that it necessarily has to be integrated into the main site, but this is just a suggestion if anyone wants to implement it.   Stack Exchange probably could make money selling the physical books though. CC-BY-SA allows selling, as long as you allow others to make copies of your book, and credit the author.  What Wikipedia does is you can custom order any set of articles as a book (it even has a nice set of authors at the end, to satisfy the BY part of CC-BY-SA).  This could even tie into the docs feature. I solved the Lagrangian of a simple pendulum (with help from online examples as this concept is new to me) and ended with the following: $$\ddot{\theta}+\omega^2\theta=0$$ But in the example I was following, the next line written was this: $$\theta(t) = A\cdot\sin(\omega t + \Phi)$$ And I don't know what steps they took to get there? Does Mathematica have a "MATLAB Builder" equivalent? Instantiating object of type parameter Find lines from a file which are not present in another file Does the MacBook battery cycle count reset when replacing a battery I've been  on battery cycle counts and checked out my current count on my MacBook (13-inch, Aluminum, Late 2008) - recommended maximum cycle count is 500.  I've had this laptop now for over 4 years and at the 2 year mark I had the battery replaced by AppleCare. The first time I checked out the cycle count was today and it's currently on 1004. Now my question is, is this the cycle count of the battery since I replaced it (as in, it reads the cycle count from the battery), or is it the combined cycle count (as in, it stores the count somewhere and increments occasionally)? My assumption is that it's the count of that battery but I have no idea how to verify this.  Either way, it looks like I need a new battery ;) I have an integrated webcam in my laptop. I know that it works and that ubuntu recognized it because at installation it asked if I wanted a photo taken for some kind of image associated with my account. When I look in system settings, I do not see any webcam in the hardware section. I would like to disable the webcam like you can do in Windows, but as I can't find it in my hardware section, how can I disable it? I cannot even unplug it as it is integrated into the monitor. Am I looking in the wrong place?? I am using 12.04 I've recently taken up a position in an all Mac workshop - We have Intel based Apple machines. Can I dual boot Ubuntu on my machine, if so how? External program from our Java program How can I write a program in Java that will execute another program? Also, the input of that program should be given from our program and the output of that program should be written into a file.  This is my small set of code to get its output:  Process p = Runtime.getRuntime().exec("C:\\j2sdk1.4.0\bin\\helloworld.java"); BufferedReader input =         new BufferedReader(new InputStreamReader(p.getInputStream())); while ((line = input.readLine()) != null)    System.out.println(line);  input.close();   This was my set of code but this throws an IOException. Is every compact subset of $\Bbb{R}$ the support of some Borel measure? I have tried to prove the exercise 2.12 in Rudin's RCA:     12 Show that every compact subset of $\Bbb{R}$ is the support of a Borel measure.   For perfect (i.e. no isolated point) compact $K$ with non-zero Lebesgue measure, we just take the Lebesgue measure. However I struck on the general case.  My attempt is as follows: For every compact $K$, we can find a decreasing sequence of open set $\langle W_n\rangle_n$ s.t. $\bigcap_n W_n =K$ and $m(W_n-K)&lt;1/n$. Find a continuous function $h_n$ s.t.   $h_n(x) = 1$ for $x\in K$ and $h_n(x) = 0$ outside of $V_n$.   (such function exists by Urysohn's lemma.) For continuous function $f$ with compact support define $$\Lambda f = \lim_{n\to\infty}\frac{\int_\Bbb{R} fh_ndm}{\int_\Bbb{R} h_ndm}.$$  I can not certain that the $\Lambda$ is well-defined. But if it is well-defined, then it gives an regular Borel measure (by Riesz representation theorem) $\mu$ s.t. $\mu(K)=1$. I guess that the $\mu$ has a support $K$ but I don't know how to get it. Thanks for any help! How do I delete a folder that's in use? Sometimes when I'm working in Windows I'll get this prompt when I try to delete a directory:    Folder In Use The action can't be completed because the folder is open in another program Close the folder and try again.   However, the folder isn't "in use" at all, and I don't have it open. So how can I delete it short of rebooting? (weak) homotopy equivalence I can follow the proofs in which the asymptotic normal-distribution of a maximum likelihood estimator $\tilde{\theta}_n$ is derived.   however, does this already imply that the maximum likelihood estimates are asymptotically unbiased, i.e. do we have $$E(\tilde{\theta}_n) \to \theta \text{ as } n \to \infty?$$  Since I am aware that in general it is not true that convergence in distribution implies convergence in moments, an explanation would be nice.  The result is often stated e.g.  as "...it means that the bias of the maximum likelihood estimator is equal to zero up to the order $n^{-1/2}$")  1.) Are  some kind of regularity conditions from the mle theory used to establish this result?  2.) Or is a $\sqrt{n}$-convergence of an estimator (to a normal distribution) in general already enough to establish convergence of its moments?  Note: the Wikipedia article mentions Cox, David R.; Snell, E. Joyce (1968).  , as a source where the order of the bias is derived (formula (12) or (20)).   However in this paper I can't follow the arguments 100%, since their Taylor approximation of $L'(\widehat{\beta})$ is lacking the remainder term. What is the argument used here to discard it completely? Java Server Socket not connecting Difference between Unity and GNOME I often come across the terms Unity and GNOME while reading about Ubuntu.
