Short story about space cadets and the core sentence “God bless you” This an old story, starts with a space cadet starting at the academy, all the hard work getting through it, a lecture about the core sentence 'God bless you', the cadets qualifying and jetting off everywhere. It ends with one of the cadets coming back years later as the commodore, remembering everyone and most especially one of the staff members and saying 'God bless you'.
Looking for Scifi Short Story in a Jerry Pournelle edited Anthology I'm looking for the title of the short story, and any of the volumes of anthology it may have appeared in. I know for SURE it's in one of Jerry Pournelle's anthologies, either Star Empires and There will be War, but as I have all the eBook version of THere will be war, I'm almost certain it wasn't there.   Anyway, the book is about a Commodore who went back to the academy to visit. I'm not sure what his name was, but I'm pretty sure he lived at "Mercer Hall". He had 2 roommates, and a butler to take care of all their needs, like putting away their stuff. (He even tried to argue with the hall monitor) The butler once took away their bottle of booze UNTIL they study for mid-term, and only gave it back AFTER they wrote to their mother AFTER the exam.   The book also goes heavily into "Bless you!" or the translated version, "May the great cosmic magnificence be benevolent toward you" or something like that. Basically, it's about as inoffensive as possible, and if you say it enough, and the aliens are reasonable, they will give up and things will resolve peacefully.   My Google-fu is weak and I can't find this particular story, or which volume of anthology was it in.   Little help?
What is the difference in meaning among these sentences? Walking is good exercise. Walking is a good exercise. Walking is a good form of exercise.     I'd like to know the difference in meaning among these sentences. Thanks a lot. It looks like if I load dynamic content using $.get(), the result is cached in browser.  Adding some random string in QueryString seems to solve this issue (I use new Date().toString()), but this feels like a hack.   Is there any other way to achieve this? Or, if unique string is the only way to achieve this, any suggestions other than new Date()? How do I set environment variables from Java? After searching here:    I am still curious about this.  Is it possible to derive the standard error of a regression coefficient from summary data alone?   E.g., assume we are given the following variance-covariance matrix.  $\begin{bmatrix}Var(X) &amp; Cov(X,Y)\\Cov(X,Y) &amp; Var(Y)\end{bmatrix}$  We can derive the regression coefficient $\beta_{XY} = Cov(X,Y) / Var(X)$.  Given a specific n, is it possible to derive the standard error of $\beta$ as well? If so, which formula is being used? It appears that all formulas for regression standard errors that I could find assume that you know the variance of residuals of the regression, which we don't know from summary data alone.  ---UPDATE--- Based on feedback by Greg and whuber, I am now at a point, where I know that  $\sigma^2(b) = \sigma^2(X'X)^{-1}=\sigma^2(Var(X)(n-1))^{-1}$,  but typically matrix formulas for the standard error of $b$ then note that $\sigma^2$, the unknown variance of the errors, is estimated with MSE.   Based on comments by whuber, sum of squares residuals is:  $Y'Y - bX'X$, which according to Greg can be spelled out as  $Var(Y)(n-1) - b(Var(x)(n-1))$  And to go from here to MSE, I think (?) all that is left is divide by n-2,  so $(Var(Y)(n-1) - b(Var(x)(n-1))) / (n-2)$  And plugging this all in yields:  $\sigma^2(b) =((Var(Y)(n-1) - b(Var(X)(n-1))) / (n-2))\times(Var(X)(n-1))^{-1}$  I will try to see if this works out in R, and will report back. If anyone sees something blatantly wrong, I appreciate the heads up. $1^n +2^n + \cdots +(p-1)^n \mod p =$? Calculate for every positive integer $n$ and for every prime $p$ the expression  $$1^n +2^n + \cdots +(p-1)^n \mod p$$    I need your help for this. I don't know what to do, but I'll show you what I know.   Wilson's theorem The identity $X^p-X = \prod_{a \in \mathbb{F}_p-1}(X-a)$ $\exists a \in \mathbb{Z}, \ a^2 \equiv -1 \mod p \qquad \iff \qquad p \equiv 1 \mod 4$   Now can you please provide me a hint? Where can I find Dogmeat after dismissing him to Sanctuary Hills? I recently dismissed Dogmeat in favor of Codsworth, and I'm fairly sure I sent him to Sanctuary Hills. However, I've had a fairly detailed look around the place and I haven't found him yet. Does anyone know where he is? Primitive polynomials I am revising for a discrete mathematics exam and as quite stuck on this question.  Show that the polynomial $f = x^2 + 2 x + 3 \in \mathbb{Z}_5[x]$ is primitive. How many monic primitive quadratic polynomials are there in $\mathbb{Z}_5[x]$?  Any help would be greatly appreciated. How to put terms in lexicographic order? Is there a function or method to give the last day of a month? For example if the date is 27 feb 2013, the last date should be 28 feb 2013 , it become 29 if its a leap year. if the date was 2 jan then it should return 31 Jan.  If there is no function then any ideas on how we can get this?  Thanks Can a character escape the  (DMG p. 177, listed in the SRD as the ) with the  spell? To clarify, I am not asking if the bands prevent teleportation. I am asking whether the bands are teleported with the character as he teleports using misty step. The question is about the encryption equation in asymmetric encryption.  For $c\equiv m^e\bmod n$, prove that for every unique $m$ there is a unique $c$.  Here $n=pq$ where $p$ and $q$ are primes larger than $m$ and the exponent $e$, is $\geq3$ and coprime with $p-1$ and $q-1$.  Thanks! How should we handle downvote retaliation? Stop setInterval call in JavaScript My friend and I have been wracking our heads with this one for the past 3 hours... We have 2 point masses, $m$ and $M$ in a perfect world separated by radius r.  Starting from rest, they both begin to accelerate towards each other. So we have the gravitational force between them as:  $$F_g ~=~ G\frac{Mm}{r^2}$$  How do we find out at what time they will collide?  What we're having trouble with is this function being a function of $r$, but I have suspected it as actually a function of $t$ due to the units of $G$ being $N(m/kg)^2$.  I've tried taking a number of integrals, which haven't really yielded anything useful.  Any guidance?  No, this is not an actual homework problem, we're just 2 math/physics/computer people who are very bored at work :) A very recent post asking people to go "on strike" was just deleted While executing an INSERT statement with many rows, I want to skip duplicate entries that would otherwise cause failure. After some research, my options appear to be the use of either:  ON DUPLICATE KEY UPDATE which implies an unnecessary update at some cost, or INSERT IGNORE implies an invitation for other kinds of failure to slip in unannounced.  Am I right in these assumptions? What's the best way to simply skip the rows that might cause duplicates and just continue on to the other rows?
