I'm actually trying to pin down an anthology and this is the only story I can remember being definitely in it.  A boy (maybe called Christopher) is visited by aliens who agree to carry out his every wish.  He begins small but eventually is destroying cities with huge tsunamis that are being brought into being by the aliens, as per his request.  I seem to remember he knows he's doing it and there was an angle in the story explaining his nihilistic behaviour.  At the end the boy is on top of a hill looking out over the devastation he has caused (the Earth is now dead) and writes in the dust at his feet something along the lines of "I WAS (his name, possibly Christopher but not too sure).  The aliens depart and the final scene is them justifying their behaviour by stating that they are not monsters but just looking for a home.  If I can identify the story then I should be able to use isfdb.com to pin down the anthology.  The story is from the 1990s or earlier.
Looking to identify a short story I read in a sci-fi anthology as a child, about an angry, bullied somewhat misanthropic boy who is given immense near-omnipotent powers by an alien intelligence. I read this in English, sometime in the late 1990s/early 2000s. He goes on to use this power to destroy the human race, which causes him to age terribly in a very short amount of time. At the end of the story he is a lonely old man stripped of the powers he held briefly, and is alone on an isolated Earth. The aliens then proceed to invade Earth.
In Harry Potter and the Chamber of Secrets it is revealed that      Ginny is being possessed by Tom Riddle and is the one opening the Chamber of Secrets.   The book seems relatively without holes in this regard.  However in the movie when Harry discovers Justin Flinch-Fletchley we see moments prior to this      Ginny is studying in a room full of people.   This implies that the person opening the chamber of secrets couldn't have been in the chamber when the second attack occurs.  Is this just a goof in the movie or is there an alternate explanation for this?  Is the Basilisk acting on its own in the movie? Direct product of abelian groups Let $G_1,\dots,G_n$ be groups. Prove that the direct product $G_1\times\cdots\times G_n$ is abelian if, and only if, each of $G_1,\dots,G_n$ is abelian. To prove that the direct product is abelian is straightforward but what I don't understand is the converse. I have Perl code which relies on Term::ReadKey to get the terminal width. My installation is missing this module, so I want to provide a default if the module isn't present rather than throw an exception. How can I conditionally use an optional module, without knowing ahead of time whether it is available. # but only if the module is installed and exists use Term::ReadKey; ...  How can I accomplish this? Using global variables in a function Delete all files except in a certain subdirectory with find I want to recursively delete all files not accessed in a while in folder a, except all files in the subfolder b.  find a \( -name b -prune \) -o -type f -delete   However, I get an error message:     find: The -delete action automatically turns on -depth, but -prune does   nothing when -depth is in effect.  If you want to carry on anyway,   just explicitly use the -depth option.   Adding -depth causes all files in b to be included, which must not happen.  Anyone know a safe way to make this work? Do any (non-hardware) RNGs exist which could be used to create an OTP for crypto purposes? I would like to know if my brother can fly by United Airlines from USA to El Salvador, and my father, from El Salvador to USA using the same round trip ticket, both of them have the same name. C# "internal" access modifier when doing unit testing I'm new to unit testing and I'm trying to figure out if I should start using more of internal access modifier. I know that if we use internal and set the assembly variable InternalsVisibleTo, we can test functions that we don't want to declare public from the testing project. This makes me think that I should just always use internal because at least each project (should?) have its own testing project. Can you guys tell me why I shouldn't do this? When should I use private? Running 64 bit programs on a 32 bit system Before running a ridge regression model, do I need to preform variable selection? I am currently constructing a model that uses last year's departmental information to predict employee churn for the current year.  I have 55 features and 318 departments in my data set.  A good portion of my independent variables are correlated, and because of this, I believe that performing a ridge regression on my data will lead to optimal predictions when I bring the model into production.  I have studied ridge regression and understand that the lambda coefficient computed for a given predictor can minimize the effect that predictor has on the model to next to nothing.  Does this mean that performing a ridge regression means I don't have to bother with variable selection? If I do need to perform a variable selection technique, would implementing a stepwise regression and then using those selected variables in my ridge regression be a valid approach at variable selection? I already posted this question on stack exchange but was informed that stack exchange was the better platform to ask statistical questions.  I am sorry for the confusion. Is it wrong to place the  tag after the  tag? How do you apply a QgsExpression to a Label ?

I would like to know if anyone can help me with installing Ubuntu on VirtualBox Fighting Spam - What can I do as an: Email Administrator, Domain Owner, or User? This is a  about Fighting Spam.   Also related:                    There are so many techniques and so much to know about fighting SPAM. What widely used techniques and technologies are available to Administrator, Domain Owners, and End Users to help keep the junk out of our inboxes?  We're looking for an answer that covers different tech from various angles. The accepted answer should include a variety of technologies (eg SPF/SenderID, DomainKeys/DKIM, Graylisting, DNS RBLs, Reputation Services, Filtering Software [SpamAssassin, etc]); best practices (eg mail on Port 25 should never be allowed to relay, Port 587 should be used; etc), terminology (eg, Open Relay, Backscatter, MSA/MTA/MUA, Spam/Ham), and possibly other techniques. Workflow for converting LaTeX into Open Office / MS Word Format So I was taught that:  Kinetic Energy (of electron) = Energy (of photon) - Ionization Energy  If E(photon) = IE, then KE=0 of the electron.   What does this physically/theoretically mean?   My current thoughts/interpretation is that enough energy/force is applied to ionize the electron so it is 'sufficiently far' from the atom, and then I guess it just moves with whatever speed it is moving at with natural kinetic laws, since no more energy/force is being applied....?  Any clarifications would be greatly appreciated, thanks in advance. I'm trying to draw a rounded rectangle with round "holes" using  but I need the rectangle borders to be thick and "holes" borders to be thin. Is there a better way to do so than:  \begin{tikzpicture}[x=1mm, y=1mm]     % Background         \fill[fill=black!10] (1.5, 1.5) rectangle (15, -15);      % Fill     \fill[fill=black!2, even odd rule, rounded corners=0.5mm]          (0, 0) rectangle (10, -10)          (2, -2) circle[radius=1.25mm]         (2, -5) circle[radius=1.25mm];     % Rectangle border     \draw[thick, rounded corners=0.5mm] (0, 0) rectangle (10, -10);     % Holes borders     \draw[thin] (2, -2) circle (1.25mm);     \draw[thin] (2, -5) circle (1.25mm); \end{tikzpicture}   The result image should look like this: Points disappear when zooming past certain scale in ArcMap?
