I recall a novel where a kid learns psychic powers by squeezing little cubes with binary numbers on them?  Does anyone remember this story from my childhood?
I am looking for a YA book about a boy who learns to use powers from a mind-adept, in a seemingly abandoned house. The adept helps him open his mind by using a cube. One of his powers, I believe, is to go into dreams of people that  he knows. He helps his young female neighbor friend by doing this, opening a door in her mind. He tries to open the mind-door of a local older bully, but finds out the young man can't be helped because he has been abused mentally and physically. I don't believe the book I read is past 1995. It might have the word "adept" in it.

I have implemented a simple web server as a solution to a course assignment and I want to connect to this web server over the internet. I've set it up to listen on port 22881 and configured my router accordingly as the screenshot below shows    I'm able to connect to my web server locally using http://localhost:22881 and I can connect to the router's interface when I visit http://my.external.ip, but I can't connect to my web server using http://my.external.ip:22881 (I get a connection timeout). Any idea of what may be the problem?  Thanks in advance! Python gives us the ability to create 'private' methods and variables within a class by prepending double underscores to the name, like this: __myPrivateMethod(). How, then, can one explain this  >>> class MyClass: ...     def myPublicMethod(self): ...             print 'public method' ...     def __myPrivateMethod(self): ...             print 'this is private!!' ...  >>> obj = MyClass() >>> obj.myPublicMethod() public method >>> obj.__myPrivateMethod() Traceback (most recent call last):   File "", line 1, in  AttributeError: MyClass instance has no attribute '__myPrivateMethod' >>> dir(obj) ['_MyClass__myPrivateMethod', '__doc__', '__module__', 'myPublicMethod'] >>> obj._MyClass__myPrivateMethod() this is private!!   What's the deal?!  I'll explain this a little for those who didn't quite get that.  >>> class MyClass: ...     def myPublicMethod(self): ...             print 'public method' ...     def __myPrivateMethod(self): ...             print 'this is private!!' ...  >>> obj = MyClass()   What I did there is create a class with a public method and a private method and instantiate it.  Next, I call its public method.  >>> obj.myPublicMethod() public method   Next, I try and call its private method.  >>> obj.__myPrivateMethod() Traceback (most recent call last):   File "", line 1, in  AttributeError: MyClass instance has no attribute '__myPrivateMethod'   Everything looks good here; we're unable to call it. It is, in fact, 'private'. Well, actually it isn't. Running dir() on the object reveals a new magical method that python creates magically for all of your 'private' methods.  >>> dir(obj) ['_MyClass__myPrivateMethod', '__doc__', '__module__', 'myPublicMethod']   This new method's name is always an underscore, followed by the class name, followed by the method name.  >>> obj._MyClass__myPrivateMethod() this is private!!   So much for encapsulation, eh?  In any case, I'd always heard Python doesn't support encapsulation, so why even try? What gives? Which statistical test to analyse? I am trying to find out how inflammatory markers change in response to a mechanical device change. I have daily readings for the 5 days before the event and for the 5 days after the event. I am expecting a rise in inflammatory markers in the pre readings followed by a fall after the device change. I also need to find out how the change differs in two subgroups (sample sizes of the subgroups are n=21 and n=88). The aim is to find out if the change is significant, to consider these markers as predictors of the device failing and hence needing to be changed.    I would like to know what test would be appropriate to analyse this. I need to keep things simple as I and the people reading the results are non-statisticians. How do I make a bootable Ubuntu USB? How do I make an Bootable Ubuntu USB containing the the latest version of Ubuntu?  For completeness, how would I be able to do this on Ubuntu, Windows, OS X or another Linux distro? Difference in meaning and use of future perfect forms I think this is just something I've grown used to but can't remember any proof.  When differentiating and integrating with trigonometric functions, we require angles to be taken in radians. Why does it work then and only then? Equidistant points across Bezier curves What is the smallest positive integer $n$, such that there exist positive integers $a$ and $b$, with $b$ obtained from $a$ by a rearrangement of its digits, so that   $a – b = 11\dots 1$ (The number of '$1$'s equal to $n$)?   Is there any example that can satisfy the equation? During the 'Hard Answers' Thieves Guild quest, Karliah asked me to meet her at the Ragged Flagon.  However, it seems that she doesn't show up at the rendezvous point.  Where do I find her? I'm considering buying the MacBook Pro (Late 2016) with Touch Bar. As I'm a programmer and a Ubuntu user, could anyone tell me if the Touch Bar is compatible with Ubuntu? $$\tan(\theta_1+\theta_2+\cdots+\theta_n)=\frac{S_1-S_3+S_5+\cdots}{1-S_2+S_4+\cdots}$$  where  $S_i$ denotes the sum of product of tangent of angles taken $i$ at a time.     For example,$$\tan(\theta_1+\theta_2)=\frac{S_1}{1-S_2}=\frac{\tan\theta_1+\tan\theta_2} {1-\tan\theta_1\tan\theta_2}$$   (This formula is given  in my textbook with no derivation or background)  How to derive this? On many occasions, I've found questions that should be moved to AskUbuntu, or Unix/Linux, but when I click the "flag" link, I don't have those as options. I hate to leave something flagged as off-topic with no suggestion of where to put it, so I just cancel.   What determines the sites that show up on that list? Is it best to flag them off topic even if the ideal site doesn't appear? Easiest way to delete a column? I have a set of 10 tables and each has an extra column that I don't want. Specifically, these tables are descriptions of database tables exported by phpMyAdmin, and they all have a "MIME" column that I would like to remove. Is there a way to do this other than using string manipulation / find and replace?   I have tried setting the column to p{0in}, but the column title still remains. Prove that a subset of a separable set is itself separable Is there anything canon in the Terminator Universe that picks up where Terminator: The Sarah Connors Chronicles leaves off? So, Terminator canon is pretty twisted, given all that time-travel stuff.  But in the canon that includes the T:SCC, does anything pick up where the show left off that is considered canon? Why was this scene from the trailer not in the film? I had seen all the trailers of  before its release. In one of those trailers Uncle Ben (Martin Sheen) says to Peter,       Do you have any idea what you really are?   This seems to imply that Uncle Ben knows about Peter's identity. This would have been a huge spoiler. But when I saw the movie, there was no such scene.   Do the filmmakers discuss such spoilers with some of the audiences and see if they like it and then change it accordingly? Or was this scene cut for other reasons? Usage of singular or plural SI base units when written in both symbol as well as name I have multiple doubts related to the usage of singular or plural SI base units when written in both symbol as well as name.  I have framed this question under two parts, namely, Part (a) and Part (b). Each part has three sentences which I have written on the basis of my understanding.  Please answer these 6 sentences/questions.   Part (a):   says that while using prefix for e.g., centi as in centimeter, it is   l = 75 cm long.(correct) l = 75 cms long. (wrong)    Does this rule is used for all SI prefixes (having powers of 10)? In this regard, we should be saying, or writing that, "how many cm are there in one metre?" (while saying we should say centimter or centimetres?) Please strike-through the wrong SI unit in the following sentences.  My weight is 70 kg / kgs,  or My weight is 70 kilogram / kilograms.   Part (b):  and the page next to above web link says, we should write:  2.6 m/s, or 2.6 metres per second.   In this regard, we should say, or write:   Its speed is 0.26 metres per second.  This pipe is 0.75 metres long. How many cm are there in 2 metres? In  (2014) the human race seemed to be facing pretty poor odds until they discovered a convenient wormhole placed by an unknown entity expressed as "they". Later in the movie, we discover that       "they" are actually the human race in the future, reaching back in  time to save itself.   The end of the movie gets a little wild on the physics end, and I'm happy to take that ending as is - no need for it to make sense - but one very basic detail does bother me:  How could the human race have gone back in time to save itself from circumstances that would have caused us to go extinct without our own help (the convenient wormhole)? Proving that if $f: \mathbb{C} \to \mathbb{C} $ is a continuous function with $f^2, f^3$ analytic, then $f$ is also analytic Let $f: \mathbb{C} \to  \mathbb{C}$ be a continuous function such that $f^2$ and $f^3$ are both analytic. Prove that $f$ is also analytic.   Some ideas: At $z_0$ where $f^2$ is not $0$ , then $f^3$ and $f^2$ are analytic so $f = \frac{f^3}{f^2}$ is analytic at $z_0$ but at $z_0$ where $f^2$ is $0$, I'm not able to show that $f$ is analytic.
