How do I uninstall Internet Explorer from windows?

Seems simple, right? Well it's not listed as a program, and no updates. So uninstalling from control panel is out of the question. And deleting them manually give a "You need to be TrustedInstaller" message. So Of course I Googled it, and I tried to follow the steps to give my user account full-access to the files of Internet Explorer but it won't let me edit it from properties. So my theory here is that by figuring out how to get into some ultra-super-secret-high-security portion of windows I can change the settings and hopefully leave with minor damage to my operating system.  So can one of you please show me how to uninstall this. Keep in mind that I'm not just some idiot with a laptop, uninstalling programs is a piece of cake. But I think the problem is IE was installed when I got the computer which means it's one tough cookie to get off.  It's a windows 7, Internet Explorer does not tell me it's version, but by comparing pictures of internet explorer's I can conclude that it's ie9 or later.


Analysis Prelim Question, showing $f(ny)\to 0$, as $n\to \infty$ implies $f(y)\to 0$ as $y\to \infty$

In preparing for the quals, I stumbled across this question: Let $f$ be a continuous real-valued function on $[0,\infty)$ with $f(0) = 0$. Suppose that for each $y\in [0, 1]$ we have that $f(ny)\to 0$ as $n\to \infty$ through the integers. Prove that $f(x)\to 0$ as $x\to \infty$ through the reals. So, In trying to prove it I knew that if it were not the case then for some $\epsilon > 0$ we have that there exist non-degenerate closed intervals, $A_n = [a_n, b_n]$ such that $a_n  \rightarrow \infty$ and $f(x) > \epsilon$ for $x \in A_n.$ Perhaps then, I thought, an infinite number of $A_n$ non-trivially intersect, for a fixed $k$, $R_k = \{$Rationals with denominator $k\} $. If this were the case, then $f(n/k)$ would not got to 0 as $n \rightarrow \infty$. Unfortunately~! My attention was then brought to the counterexample of $A_k = [k + 1/k, k + 2/k]$... Darn. So, I guess that I need to use an irrational? I am not entirely sure... Any hints/insight would be most appreciated.


Limit of integral $\lim_{n \to \infty} n\int_0^{\frac{\pi}{4}} \tan^n x\,dx$

Compute  $$\lim_{n \to \infty}n \int_0^{\frac{\pi}{4}}\tan^n x\,dx$$  I tried to define a recurrence with $I_n=\int_0^{\frac{\pi}{4}} \tan^n x$ :  $I_0 = \frac{\pi}{4}, I_1=\ln\sqrt{2}$  and $I_{n}=\frac{1}{n-1}-I_{n-2}$, but I can't complete it.


Prove that $\sum _{n=1}^{\infty }\frac{\sin n}{n}$ converges or diverges.

My guess is that it diverges because 1/n diverges and sin is bounded between [-1,1]; however, I know that the product of two divergent series may yield a convergent. Any suggestions of going about this?

just wondering if anyone has ever tried embedding and actually integrating any js engine into the .net environment. I could find and actually use (after a LOT of pain and effort, since it's pretty outdated and not quite finished) spidermonkey-dotnet project. Anyone with experience in this area? Engines like SquirrelFish, V8..   Not that I'm not satisfied with Mozilla's Spidermonkey (using it for Rails-like miniframework for custom components inside the core ASP.NET application), but I'd still love to explore a bit further with the options. The command-line solutions are not what I'd need, I cannot rely on anything else than CLR, I need to call methods from/to JavaScript/C# objects.  // c# class public class A {     public string Hello(string msg)     {         return msg + " whatewer";     } }  // js snippet var a = new A(); console.log(a.Hello('Call me')); // i have a console.log implemented, don't worry, it's not a client-side code :)   Just to clarify - I'm not trying to actually program the application itself in server-side javascript. It's used solely for writing custom user subapplications (can be seen as some sort of DSL). It's much easier (and safer) to allow normal people programming in js than C#.


Traveling Amsterdam-Brussels with KLM ticket on Thalys: When / where does my ticket get stamped?

I am re-posting this question, because it was marked as duplicate. However, the other ask-and-answers did not address my key question: Where/when during the Thalys ride does the ticket get stamped? This is important to anyone in my situation -- i.e., needing to return to Amsterdam after boarding the Thalys, but needing their ticket stamped to ensure their return itinerary is not cancelled.  Original question   Supposed duplicate   I purchased a ticket to Brussels via Amsterdam on KLM, with the Schiphol to Brussels-Midi portion on the Thalys. The return portion of my itinerary is on Air France several days later. This was done in good faith (i.e., not as a fare dodge) since I really do need to go to Brussels.  However, it now turns out that I have a meeting in Amsterdam the day I arrive.  I realise I am required to board the train to Brussels to fulfil the terms of my KLM ticket, and that I will need to get my ticket stamped on the Thalys in order to board my return flight. What I want to know is where and when this takes place, since I need to return to Amsterdam. Will I need to ride the train all the way to Brussels, or can I get my ticket stamped and then disembark in Rotterdam or Antwerp?  Alternatively, is there any possibility of getting my KLM Thalys ticket issued for a later train, so that I can attend my meeting in Amsterdam before heading to Brussels?


How are $\hat{\beta}$ and $\hat{\sigma}^2$ independent in OLS when assuming that $\epsilon \sim N(0, \sigma^2)$?

In Elements of Statistical Learning, pg 47, at the very bottom, it states that $\hat{\beta}$ and $\hat{\sigma}^2$ are statistically independent. Is this saying that they are independent when conditioned on $X$, or is it saying they're marginally independent? If it is saying they're marginally independent, which seems to be the case in the book, I'm confused because it would seem they're not marginally independent. We know that $$ \hat{\beta} = (X^TX)^{-1}X^Ty$$ $$\hat{\sigma}^2 = \frac{1}{N - p - 1} ||y - \hat{y} ||_2^2 = \frac{1}{N - p - 1} ||y - X\hat{\beta} ||_2^2 $$ By inspection, $\hat{\sigma}^2$ is a function of $\hat{\beta}$, so it's not obvious how the two are marginally independent.


Do you delete your own answer when it's a duplicate?

When I post an answer to a brand new question I usually find that someone else has submitted that same answer just moments before. (, usually ;-) )  What I've started to do lately is (I think) the right thing.   If I notice that another answer predates mine, and that I add no value over it, I immediately delete my own answer, and upvote the other guy.  I recommend that you too do the same. Otherwise the message will be diluted.  Similarly, if after posting your "answer" you realise that you are in fact wrong (and you've just misread the question) -- you can actually delete your answer.  Is this reasonable?  (The reason why I'm writing this down is because it feels completely counter-intuitive to delete your own stuff. But it really saves everyone time and effort)

How do I merge all coinciding vertices using a Python script?

I've spent awhile using the extrude tool to construct a mesh, but once problem I've noticed is that if I'm creating a shape with some kind of concavity and two parts of the mesh come back together, then there are two faces pointing into each other and each one has its own set of vertices. I've been consistently entering numbers when extruding so I know that the vertices are in exactly the same position, aside from a possible small amount of floating-point error.  I found  about merging vertices to create a pyramid, but the answers on it are only applicable to creating pyramids and similar shapes, since they are about manually selecting one of the cube faces to collapse. My mesh likely has hundreds of these duplicated vertices and manually checking the entire mesh is not an option, so I either need to use a tool or get a Python script to automate the process. However, the Alt+M functionality in that question looks useful, since it seems to be able to merge arbitrary vertices.  How do I merge my vertices together? Is there some kind of Python script I can use? Is there a way I can iterate through all of the vertices, check if any two are equal in position, select them, perform the Alt+M functionality from Python, and repeat for all vertices? Since merging vertices would change the amount of vertices, the entire script would basically need run itself many times to merge all of the coinciding vertices, or somehow loop until it finds no coinciding vertices.


How to create identical PDF files with xelatex?

The question how to create identical PDF files with pdflatex was basically answered in this question already:    The catch was to filter out the entry /ID in the trailer dictionary after the PDF file was created.  I am now forced to use xelatex and there this trick does not work any more, because there are many more changes in the resulting PDF files.  Here is the minimal working example again:  \documentclass[11pt,a4paper]{article} \usepackage[]{hyperref} \hypersetup{         pdfauthor={None},         pdfcreationdate={D:20131010120000},         pdfmoddate={D:20131010120000} } \begin{document} foo  \end{document}   If I now create 2 PDF files, convert them to a hex dump and view the differences...  xelatex mwe.tex; mv mwe.pdf a.pdf; xxd a.pdf > a.bin xelatex mwe.tex; mv mwe.pdf b.pdf; xxd b.pdf > b.bin diff -u a.bin b.bin    ... then you can see that there are many differences in the resulting PDF files unfortunately.  Is there any way to produce bitwise identical PDF files with xelatex?  The reason I need this is that I'd like to create PDF files for a software release package. Of course the software release package should be identical when the underlaying software and documentation has not been changed.

MySQL Error 1153 - Got a packet bigger than 'max_allowed_packet' bytes

I'm importing a MySQL dump and getting the following error.  $ mysql foo < foo.sql  ERROR 1153 (08S01) at line 96: Got a packet bigger than 'max_allowed_packet' bytes   Apparently there are attachments in the database, which makes for very large inserts.

Creating intuition about Laplace & Fourier transforms

I've been reading up a bit on control systems theory, and needed to brush up a bit on my Laplace transforms. I know how to transform and invert the transform for pretty much every reasonable function, I don't have any technical issue with that. My only problem is that some theoretical things are not entirely intuitive.  This is my current understanding of the Fourier transform: We have an function, member of an infinite dimensional space, and we want to decompose it in terms of basis functions $e^{j\omega t}$. To do so, we project (analogously to taking the dot product) our function onto the basis functions, using the following definition of an inner product for the function space: $\langle f, g\rangle = \int_{-\infty}^{+\infty}f(t)\cdot g^*(t)dt$, which gives rise to the Fourier transform: $F(j\omega) = \int_{-\infty}^{+\infty} f(t)\ e^{-j\omega t}\,dt$. Reconstructing the original function from the coefficients times the basis functions gives $f(t) = \frac{1}{2\pi}\int_{-\infty}^{+\infty} F(j\omega)\ e^{j\omega t}\,d\omega$  Now, looking at the definition of the Laplace transform, it looks like it's trying to do the same thing using underdamped/overdamped sinusoids of the form $e^{\sigma t}e^{j\omega t}$, instead of pure sinusoids like the FT. This enables representing functions which don't vanish at infinity, but rather can diverge exponentially. However, it doesn't quite fit in the framework I laid above. First of all, the inversion integral confuses me. $\mathcal{L}^{-1} \{F(s)\}(t) = f(t) = \frac{1}{2\pi j}\int_{\sigma-j\infty}^{\sigma+j\infty}F(s)e^{st}\,ds$. Why am I free to do the integration for any value of σ, as long as it's bigger than the real part of the rightmost pole? If I plug  in $s = \sigma + j \omega, ds = j d\omega$, I can pull $e^{\sigma t}$ out of the integral, to get $\mathcal{L}^{-1} \{F(s)\}(t) = f(t) = \frac{e^{\sigma t}}{2\pi}\int_{\infty}^{+\infty}F(\sigma+j\omega)e^{j\omega t}\,d\omega$. It appears strange to me that the $e^{\sigma t}$ term has to be exactly compensated by the fact that the transform is being evaluated more to the right or to the left. Also, when analyzing systems using the Laplace transform, the main thing we're interested in is the location of its zeros and poles. Intuitively, I would expect that, since the function "blows up" at the poles, there would be large contributions from those amplitudes in the inversion integral if it passed near the poles. However, if it can pass arbitrarily far away from the poles, it doesn't make as much sense...  I'm sorry if I'm not explaining myself as well as I wanted to, but this isn't really that easy to express...  Cheers

Derivation of conditional expectation and variance of the AR(1) process

I have a question regarding the AR(1) process. I want to derive the conditional expectation $E(X_{(t)}| X_{(0)})$ and the variance $\operatorname{Var}(X_{(t)}|X_{(0)})$ of the AR(1) process: $$X(t)=aX(t-1)+Z(t)$$ Where $Z(t)$ is i.i.d. normally distributed with standard deviation $b$. Does anyone knows how to do it?


Ubuntu on 32-bit UEFI (only) based tablet pc

I've created a bootable USB of Ubuntu 16.04 64-bit with Rufus, setting the drive to be a GPT for UEFI. Then I booted my tablet PC and I ran the UEFI BIOS, from which I turned secure boot off. I then restarted and went again on the BIOS to boot from my key, but all I got was a black screen that lasted few seconds and then it brought me back to the BIOS. I read about a bootia32.efi file and other procedures that can be followed, but I didn't find a good explanation of what I need to get done. My tablet PC runs an Intel Core Atom Z3735F and has 2 GB of RAM. If you have the answer please let me know.

So I am wondering how to also display series, year and pages.

Is the current outrage by the long time community contributors really about pronouns/trans people/Monica?

This question has nothing to do with whether or not SE wants to fix   things or engage with the community, the answers to that are already   known: ‘nothing to fix’ and ‘no’. This is about the origins of the   discontent with the way the long time veteran community as a whole has   been vilified and blamed for the few rate bad actors in the past and   used as a scape-goat for whatever the corporate entity has in mind for   their future to save their reputation or whatever.   TL;DR  It is not and never has been  It is not, and it is not about Monica either, she is caught in the middle of something, made a public example of as a warning, and all that was completely avoidable regardless of her opinion on the pronouns and the CoC.  It is just the logical backlash against the continuation of the blanket vilification that the Stack Overflow community experienced with the Jay Hanlon , but now applied/implemented against the entire StackExchange of communities.   There are many that are on the autistic spectrum that are probably an inordinate percentage of the technical communities, especially Stack Overflow, and when they get accused of malice when there is none and without any proof in the comments and their flags of abuse are ignored and they are sent curt messages by the moderators handling the flags to suck it up, or that they are mocking someone when they are asking a legit question in all sincerity, it seems like a double standard and hypocrisy at its most egregious cases.   I am done with the abuse here, from the moderation staff, from those that just want to lash out at everyone and accuse everyone of everything implicitly just because that is the popular thing to do right now. And to paraphrase Jay Hanlon,      I know when I am not wanted or appreciated, you know how? Because, you   told me so ...   The first 3 or 4 dozen times should have been enough of a message, but then again, those of use that are on the spectrum do not get the hint as easily as others.   And to those that think, good the problem people are self removing themselves, good riddance, I put 10 years into SO, had a huge impact number and never once was abusive to any group. I was vocal when people attacked me or my character in public comments and their comments were allowed to stand because they were part of the cool kids weaponizing the first CoC changes, because well they were better at manipulating language and people to language lawyer their abuse as polite,  when one person did comment in my defense that polite abuse is still abuse they got their comment deleted as well. You are losing allies, with no sarcasm, your online paradise you are creating, I hope you get what you want.  This outcome, this place the sites are in, is not unexpected and could be completely predicted and completely avoided.

So I need to replace my inner tube as it got destroyed beyond any repair I can make (a hole right under the valve) but unfortunately I dont know what size the inner tube should be and I cannot figure out the different types of measurements of tubes. The metal part of the wheel has the markings 700x22 A/C, while the inner tube is too worn out to make out anything on it (Ive had it for like 2 years and I patched it 3 times :D )  The wheel is on the front and its a mountain bike, If that matters.


What is the order of any type of "resurrection" in League of Legends

I know that there are several types of resurrection skills in LoL. What do I mean by the "resurrection" term?  Following skills and items can be categorized under the term "resurrection":   Champion Passive - Aatrox Passive  Item - Guardian Angel  Champion Skill - Yorick - Ulti  Champion Skill -Zilean - Ulti   To combine all of this, all of the other skills and items should be used on Aatrox. I'm just curious about what order these skills will take effect? Assuming;   Skills used just before first death  There is continuous damage that is applied on the champion Aatrox (say 3k true damage per second)   With above assumption what will happen? Has anybody ever tried this?  Note: If I forgot to mention any skill, passive or item that resurrects the applied champion please indicate them, too.


How to install system drivers after a clean install of W10

Ive got an error on a windows 10 HP laptop with the OS and i need to do a clean install of the W10.   Ive never done a windows clean install (done plenty of Mac ones) so im trying to figure out everything i need in advance.   So far my plan is to :   backup all data download W10 from microsoft  , install it onto a USB drive, boot into the drive and run the installer   Once the clean install of W10 is complete as i understand i need to install drivers for various bits of hardware, for this HP have a driver page for my laptop . Where i currently cant make my mind up is wether i should download the individual drivers from that page and install them (the issue with this is im a bit confused on some of them as there seem to be 2 bluetooth drivers, and other options on a couple of other drivers, due to what hardware the specific laptop has).   I was also told to check out the HP Setup Assistant software which apperently functions like a driver install wizard, by scanning your hardware and then downloading the required drivers.   What is preferable to download the individual drivers or the use the HP setup assistant ?   Is there also a test / tool i can run at the end of the processes after the new OS and drivers have been installed, to check nothing is missing ?   Will i need to enable security features etc, or does a clean copy of W10 default to a locked down mode ?


How do I create a generic class from a string in C#?

I have a Generic class like that :  public class Repository<T> {...}   And I need to instance that with a string ... Example :  string _sample = "TypeRepository"; var _rep = new Repository<sample>();   How can I do that? Is that even possible?  Thanks!


Suppose that the series $\sum_{n=1}^\infty a_n$ is conditionally convergent. Prove that the series $\sum_{n=1}^\infty n^2a_n$ is divergent.    How should I start to prove this? I have absolutely no idea how to go about solving this problem. Thanks in advance!


I am writing simple code by overriding hashcode and equels method can any one plz expline me how that will work exactly if i overried or not overried in my class.     class HexToDec {       public static void main(String[] args) {             Test t = new Test();     //        Test t1 = new Test("Aamir", true, "good lead, choclate hero");             Test t3 = new Test();             Test t4 = new Test();             t4.setName("ranjith");             System.out.println("a1.hashCode() = " + t);             System.out.println("a2.hashCode() = " + t4);             System.out.println("a1.hashCode() = " + t3.hashCode());             System.out.println("a2.hashCode() = " + t4.hashCode());     //        System.out.println("is a1 == a2 " + (t == t1));             System.out.println("is a1.equals(a2) " + (t3.equals(t4)));         }     }

How do we use a abstract class as a function return type?

What's the C++ way of returning a derived type as a abstract type in a function with this caveat?  Say the function creates a derived type and wants to return that object as the abstract base type. How do you do that in C++ without resorting to messy C like  pointers?


Usage of the word "meet" in the context of a phone call/video conference

Is it acceptable English to use the verb meet in the context of a phone call or a video conference?   To provide a bit of background, I am writing an email to a business associate overseas. There is little chance of an actual face-to-face meeting taking place anytime soon, however a phone call or a video conference would obviously work fine.  I don't want to be the one to suggest a method of communication, but would rather let the business associate decide in what way would they prefer to conduct the conversation. For this reason, I was thinking of using a neutral verb, e.g. meet. Can I use a phrase such as "I hope we can meet to discuss topic X in the near future" in the context of a phone call or a video conference?  Intuitively, I would say that this sounds a little awkward. Nevertheless, given the fact that phone conference calls are often referred to as meetings, I was thinking that this sort of usage of the word might be acceptable after all. What do you think?


Simple band arithmetic on GDAL virtual rasters (VRT)

I want to calculate the difference of two bands. I have the individual bands stored somewhere, but I was thinking that maybe there's a way of producing a VRT file that is the result of this difference. I know that you can use pixel functions in GDAL, but this limits the use (C++, and only available when the function is linked in...).  It would be nice if simple "virtual" operations were available!


MikTeX 2.9, install packages on the fly?

I set the Install Packages on the Fly setting to Yes and try to compile my document in Texmaker, but I still get the error File [...] not found, where [...] is the package I need.

How to use for-loop to initialize a list with multiple groups of elements?

I have created a list as following:  possible_team = [(t, h, dps1, dps2, dps3)                  for t in all_T                  for h in all_H                 for dps1 in all_DPS                 for dps2 in all_DPS                 for dps3 in all_DPS]   But if there are more elements in the list, such as 2t, 6h and 17dps, how can I avoid to write all the element names? such as:  possible_team = [(t1, t2, h1, h2, ... h5, dps1, dps2, dps3 ... dps17)                  for t1 in all_T                 for t2 in all_T                 ...                 for dps1 in all_DPS                 for dps2 in all_DPS                 ...                 for dps17 in all_DPS]   I have tried to write the keys as (t)*2, (h)*5 and (dps)*17:  possible_team = [([t] * 2, [h] * 5, [dps] * 17)              for t in all_T              for h in all_H             for dps in all_DPS]   but they are returned with duplicate values, and each in a list.  Is there any simple method to get a list as [t1, t2, h1, h2, ... h5, dps1, dps2, ... dps17], with each element in a single loop?

How to create a bootable Debian USB drive using Windows

I am running Windows 10 and am starting to learn how to boot from USB devices.   I have a 16GB USB (USB 3.0) drive and I want to do the following:   Make the 16GB USB drive run Debian Linux. Keep Windows 10 on my C: drive. Not partition my hard drive or set up a dual boot. Run the OS from my USB drive. Let all of my files and programs be saved to the USB (so I don't think that a live OS would be suitable). It should work as though it was a dual boot as in the way files are saved. Make it work on any computer it is plugged in to (assuming the BIOS is compatible).   I already know how to boot from a USB in my BIOS but I am unsure as to where to get an ISO file and how to install it to the USB.


What are the pros and cons of setting my camera to lock exposure on half press?

The Sony NEX-5R has an "AEL w/ shutter" option that     Sets whether or not to fix the exposure when you press the shutter   button halfway down (On/Off)   (from the manual)  What are the pros and cons to locking the exposure? Under what situations does it help, or not help?  I can think of specific examples where locking exposure helps, and examples where it hurts, but I wanted to check if there's a bigger picture I'm missing.  As I understand, this setting controls only the exposure and not the focus, which is controlled by setting the focus mode to AF-S or AF-C.  Note that this camera doesn't have an AEL or AE/AF lock button.


How do I figure the dice and bonuses for attack rolls and damage rolls?

I'm building my character, a Half-Elf Ranger, and I'm a little confused about how to work out the attack bonus and the damage bonus.  So, please tell me if I've got this right:   I'm proficient with a longbow. That means my attack roll is 1d20 + prof bonus + Dex modifier. The damage roll however is 1d8 + Dex modifier.   I'm just a little confused about working out the numbers (without even going into spells and when to roll for attack, etc.)


Show that exists a continuous function in $E$ that is not bounded

Let $E\subset\mathbb{R}$ a non-compact set. Show that      i) Exists a continuous function in $E$ that is not bounded.      ii) Exist a continous and bounded function in $E$ that doesn't have   maximum.      iii) If $E$ is bounded then, exists a continuous function in $E$ that   is not uniformly continuous   I started writting one definition that I have doubt     Def: A set $E\subset \mathbb{R}$ is compact if and only if it is   closed and bounded.   If a set is non-compact then I can say that that it is not bounded or not closed?  i) $f(x)=\sqrt{x}$ is a continous function and it is not bounded.  ii) From the doubt that I have in definition, if a set is non-compact and it is bounded then it is not closed so doesn't have a maximum.  iii) I don't know how to find a example.

Experiment proving that the Earth is rotating around the Sun

Is there any simple experiment done on Earth proving that the Earth is rotating around the Sun? Something in the same spirit of what  did proving that the Earth is rotating around itself.  P.S. I know that actually the system rotates around its center of mass. My point is to prove, by an experiment on Earth that we are rotating around some point.  P.S.2 - Done on Earth. One cannot watch the skies!


Solidify thickness doesn't correspond to specified scale

I'm Having trouble with setting the thickness applied by solidify. The selected block is 15 by 28 cm (single mesh sides) and the thickness of solidify is set to 3mm (pointing inwards). Checking off even thickness makes it even worse. I was using the function in a different object earlier today and it worked just fine. Is there something I'm missing or is this just a bug?   Feel free to treat me like an idiot, I've literally started using blender yesterday :)


I came across a line in a LaTeX file reading \pdfoptionsminorversion=6.  This changed the minor version of PDF, which I confirmed by looking at the generated PDF.

Integral $\int_{0}^{\infty} \frac{\left(\frac{\pi x}{2}-\log (x)\right)^3}{\left(x^2+1\right)^2 \left(\log^2(x)+\frac{\pi ^2}{4}\right)} = \pi$ proof

Today @integralsbot at twitter  an interesting integral relation for complicated integral that gives $\pi$ as a result. I don't know how this bot works or where does it take the relation it posts from, but some of the problems are really difficult to prove and interesting. Such as this example. $$\int_{0}^{\infty} \frac{\left(\frac{\pi  x}{2}-\log (x)\right)^3}{\left(x^2+1\right)^2 \left(\log^2(x)+\frac{\pi ^2}{4}\right)} = \pi \tag{1}\label{eq1}$$ I've tried to calculate this and it appears to be very difficult (for starters wolfram alpha can't calculate it). The plot of the function under the integral doesn't look very extraordinarily:  Using partial fraction decomposition the integral  to the following form: $$\int_{0}^{\infty} \left( \frac{3 \pi  x}{2 \left(x^2+1\right)^2}-\frac{\log (x)}{\left(x^2+1\right)^2}+\frac{\pi^3 x^3-6 \pi ^2 x^2 \log (x)-3 \pi ^3 x+2 \pi ^2 \log (x)}{2 \left(x^2+1\right)^2 \left(4\log ^2(x)+\pi ^2\right)} \right)$$ The first two terms of the integral can be  $$ \int_{0}^{\infty} \frac{3 \pi x}{2 \left(x^2+1\right)^2} = \frac{3 \pi}{4} $$ or  easily solved $$ \int_{0}^{\infty} -\frac{\log (x)}{\left(x^2+1\right)^2} = \frac{\pi}{4} $$ to yield: $$ \int_{0}^{\infty} \left( \frac{3 \pi  x}{2 \left(x^2+1\right)^2} - \frac{\log (x)}{\left(x^2+1\right)^2} \right) = \pi \tag{2}\label{eq2} .$$ This is interesting by itself, since plot of the integrated function has interesting shape with two inflection points of the first derivative, which I wouldn't expect to be equal to $\pi$ (of course the algebra clearly shows that it is)  What's however even more interesting is that, if I'm not mistaken, it follows from \eqref{eq1} and \eqref{eq2} that $$ \int_{0}^{\infty} \frac{\pi^3 x^3-6 \pi ^2 x^2 \log (x)-3 \pi ^3 x+2 \pi ^2 \log (x)}{2 \left(x^2+1\right)^2 \left(4\log ^2(x)+\pi ^2\right)} = 0 \tag{3}\label{eq3}.$$ This seems to be correct when checked with numerical integration (I've checked in relatively high precision of ~100 decimal digits) but seem to be very hard to prove. Plot of the function under the integral \eqref{eq3} doesn't appear (to me) to suggest any trivial solution:  The most obvious way to transform integral \eqref{eq3} is to expand the numerator which gives: $$  \int_{0}^{\infty} \left( -\frac{3 \pi ^2 x^2 \log (x)}{\left(x^2+1\right)^2 \left(4 \log ^2(x)+\pi ^2\right)}-\frac{3    \pi ^3 x}{2 \left(x^2+1\right)^2 \left(4 \log ^2(x)+\pi ^2\right)}+\frac{\pi ^2 \log    (x)}{\left(x^2+1\right)^2 \left(4 \log ^2(x)+\pi ^2\right)}+\frac{\pi ^3 x^3}{2    \left(x^2+1\right)^2 \left(4 \log ^2(x)+\pi ^2\right)} \right), $$ but the resulting integrals are also very difficult, perhaps too difficult to directly attack the problem in this way (I've tried to solve the second one, since it seems to have the simplest numerator, but didn't managed to get any results yet) and neither their numerical values (-1.93789..., 3.229820..., -0.322982..., -0.968946...) nor the plots indicate any obvious cancellations. Maybe there is some indirect way? Perhaps the integral \eqref{eq3} can be shown to be equal to $0$ without directly solving the integral at all? As I mentioned in the beginning of this post, I don't know where does this \eqref{eq1} relation come from but it seems to be true and interesting and must've been found somehow. Therefore I believe some solution of this problem exists. I post it as an interesting challenge/puzzle. Maybe someone knows some of the relations, can solve some of the unsolved integrals, sees clever substitution or can provide any interesting insight into this problem. So, to finally pose the question. How to prove/solve either \eqref{eq1} or \eqref{eq3}?


How can I make an EXE file from a Python program?

Let $X$ be a random variable. Suppose there exists a constant $c ∈ R$ such that $E(|X − c|^2) < ∞$. Show that the random variable $X$ has finite mean and variance.  And I'm quite confused about the definition about finite mean and variance. I searched on google, but seems there is no explanation in datail. Can anyone help me out? Thanks


Suppose we have two $n \times n$ matrices $A, B$. It seems like $\delta(AB)=\delta(BA)$, but I can't generally poove it.   If $\det(A) \neq 0$ then $\det(AB - \lambda I) = 0 \Leftrightarrow $ $ \det(AB - \lambda I) \cdot \det(A) = 0 \Leftrightarrow \det(ABA - \lambda A) = 0 \Leftrightarrow $ $ \det(A) \cdot \det(BA - \lambda I) = 0 \Leftrightarrow \det(BA - \lambda I) = 0$, so $$\delta(AB)=\delta(BA)$$ Same if $\det(B) \neq 0$.  But how to prove it for $\det(A) = \det(B) = 0$? Is it still true?


What is the word for "something that is true, but misleading"?

A person in the news recently stated that he was a "Vietnam era veteran". This misled EVERYBODY into thinking he was a Vietnam veteran (and newspapers widely reprinted that he was). But no, he merely served in the armed forces while the Vietnam war was going on, but never participated.   Is there a word for that specific kind of technically-true-but-grossly-misleading claim?  BTW I'm very liberal this is not meant to be about politics but strictly language usage, there's no doubt in my mind that calling yourself a "Vietnam era veteran" is meant to convey a false impression.


Changes to centre of gravity of a moving object

On a frictionless road and tires, I know the rider wouldn't be able to change the combined center of gravity of the system by moving his weight around. If he pushes the bike to lean to the right, he would go to the left by the amount that would keep the combined cog the same. But a bike with real tires and a real road under it is not a closed system, the tires wouldn't let the lower part of the bike left or right when trying to initiate lean.   Does this mean it is possible to push with your bodies inertia to the bike, and the combined cog will be changed?   I think if you do so below the center of mass of the bike, you could, but I am not sure, since the tires will want to move more, but won't be able to, making the combined center of gravity shift more than if you applied the force higher up. And I think you should use horizontal forces on the pegs not up/down forces on the pegs  I know counter steering is the best way, but I would like to think it is possible to change direction without it, without the influence of handlebars  Please ignore gyroscopical forces and assume the bike doesn't have any trail geometry (so you would have to "catch" the bike manually through the handlebars)


Mission Control stopped working then Dock won't restart

i am using a macbook air and with yosmite os  At first I could still switch between desktops, just that i could not swipe up/down to access mission control and app exposé. I tried typing in killall Dock into terminal to restart dock, but now i cant switch desktops either and the background is completely black. killall dock just tells me it can't find the process for this user. when i typed in killall -s dock it showed only one process.  is there a way to force dock to start and fix mission control?


Is this subset linearly independent or linearly dependent?

In the $n$-space $\Bbb R^n$ determine whether or not the set $\{e_1-e_2,e_2-e_3, \dots, e_{n}-e_{1} \}$ is Linearly Independent.  I tried solving it using the definition of a LI set, taking $e_1, e_2$ etc to be the standard basis of $\Bbb R^n$. Finally equating it to the zero of $\Bbb R^n$, I get all the scalars $a_1=a_2=\cdots=a_n$  So should I conclude that they are not necessarily zero and hence the given set is Linearly Dependent?


How to say that something is (not) random

I want to compare two things, one of which is random and the other is not, in favor of the latter. I'd like to do it in a more sophisticated way than simply using the word "random".  Like, for example,     In this case, your pay will not depend on the roll of the dice.   But Google Ngrams doesn't find a single occurrence of "depend on the roll of the dice", so I guess there's something wrong with this particular phrase. What would be a better substitute?


How do I convert this to a prepared statement in PHP

So I have already converted most of my queries into prepared statements but I'm stumped on this one. All the examples I have found are for simple one-line queries but I have one that is a little complex and bases itself off other results.  To clarify, I don't know how to make this a prepared statement so I'm asking how you would do that. I might be overthinking it but it didn't work when I tried. Deleted my source code I attempted it at last night.  <?php include_once 'includes/db_connect.php'; include_once 'includes/functions.php';  $ten_id = $_GET['parent']; $end_d = $_POST["end_d"];  $results = $mysqli->query("SELECT property_id FROM tenancy WHERE tent_id = '$ten_id' AND current = 1"); while($row = $results->fetch_array()) {  $property = $row["property_id"]; } $mysqli->query("         UPDATE tenant SET current='0' WHERE id=' $ten_id';         "); $mysqli->query("         UPDATE property SET occupied='0' WHERE id=' $property';         "); $mysqli->query("         UPDATE tenancy SET current='0', end_date='$end_d' WHERE tent_id='$ten_id' AND current = 1;         "); ?>   I'm not asking you to just convert this to prepared statements. If you do great but please explain how you got there. I don't understand how to write the first row then fetch it to get the id and then update the other 2 rows in other tables

Can Drunkard's Luck let someone gain advantage if he has advantage and disadvantage?

If I am a Drunken Master Monk and I have one source each of both advantage and disadvantage, can I still use Drunkard's Luck to remove the disadvantage as per the class feature:       When you make an ability check, attack roll, or a saving throw and have disadvantage on the roll, you can spend 2 ki points to cancel the disadvantage for that roll. (XGtE 34)     and thereby have advantage? or am I not allowed to use Drunkard's Luck because the disadvantage is already cancelled out by the advantage per this rule:     If circumstances cause a roll to have both advantage and disadvantage, you are considered to have neither of them, and you roll one d20.


Difference between logical implication and conjunction

If we are asked to convert the following two phrases into a mathematical expression, what will be the difference between using a logical implication and a conjunction expression? If we have $$P(x) = \text{x is an accountant} \\ \text{and} \\ Q(x) = \text{x owns a car}$$ and for the phrase "All accountants own cars", which one should be correct? And what is the difference? $$ \forall x, (P(x) \implies Q(x)) \ \text{and} \ \forall x, (P(x) \wedge Q(x)) $$ Similarly, for the phrase "All car owners are accountants": $$ \forall x,(Q(x) \implies P(x)) \ \text{and} \ \forall x,(Q(x) \wedge P(x)) $$ Thanks everyone!

Thank you  $\tilde{A}_{Long}=\left(\begin{matrix} X_{\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont u}}}&X_{\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont w}}}&X_q-M_{33}\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont w}}_0&-(mg-B_u)cos(\theta_0)\\ Z_{\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont u}}}&Z_{\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont w}}}&Z_q-M_{11}\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont u}}_0&-(mg-B_u)sin(\theta_0)\\ M_{\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont u}}}&M_{\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont w}}}&M_{q}-M_{11}.x_G\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont u}}_0-M_{33}.z_G\textrm{{\fontfamily{lmr}\fontshape{ui}\selectfont w}}_0&(x_Gmg+x_BB_u)sin(\theta_{0})-(z_Gmg+z_BB_u) cos(\theta_{0})\\  0&0&1&0\\ \end{matrix}\right)$


If $E = mc^2$ describes the energy-mass relationship of matter, does that mean that if we rearrange to form $m=E/c^2+pc$, does that mean that photons have no energy thus mass = $0$? Or does this mean that photons cannot have both energy and momentum?  This is just a question from a high school partner so no very big words.


How can I get Latex to use the fonts that are already on my PC via Xetex?

I am an absolute beginner with LaTeX. I have Texnic Centre and MikTeX 2.8. I just want to be able to use the truetype or opentype fonts from my C:/Windows/Fonts folder. How hard can it be? Apparently, very.   I have found a  that says I can use , but I have absolutely no idea how to use XeTeX. I think it's installed - it came with MikTeX, but I don't know how to get it working. I'd really appreciate some "baby steps" on how I can get this working.  Thanks  Edit  I have tried konrad's suggestion below and got a fontsec.cfg error. However, using the following:  \usepackage{xltxtra} \setmainfont[Mapping=tex-text]{Tahoma}   I got it to work. I don't know why the first failed and this one worked, but it does appear to be using system fonts.

Opening Raster stored in Esri Geodatabase using QGIS

Is there a way to open a raster that is stored in ESRI V10.0 Geodatabase in QGIS V2.4?    I can open the vector layer, but there does not seems to be a way to open a raster.


Concurrently interleaving execution of Lua and TeX in LuaTeX

The usual way to interleave Lua and TeX in generating documents is by invoking Lua from Tex through the \directlua facility and generate Tex from Lua using tex.print().  For example, consider the Plain LuaTeX:  \directlua{     es=""; someluatex = function () tex.everypar="PAR!" end     tex.print("one", es, "two")     someluatex()     tex.print("three", es, "four") } five\bye   Looking at the document LuaTeX generates for that input, we see that someluatex() is run before the Tex backend does anything with the output: the PAR!s will be inserted before "one" and "two", as well as after "three".  Is there best practice for ensuring that TeX code issued by some Lua code is issued before some other LuaTeX code?  There are several ways to do this: with some code I am working with I am trying the following scheme:   Wrap the code executed by the \directlua in a coroutine, call it myco; At the point we want to ensure the Tex so far tex.print-ed is executed, use:  tex.print("\\directlua{coroutine.resume(myco)}") coroutine.yield()  If everything is in order, the Lua will resume after the Tex is processed.   This is not ideal, however: we must ensure that the TeX backend is in the right state to understand the \directlua command, which may not always be the case.  Is there a better way to achieve this?


Where is the option to flag a question off-topic and it doesn't qualify for any suggested site?

I recently encountered  and it doesn't seem relevant for SO (maybe I'm wrong!) or any of the suggested options that flagging "this is off-topic..." suggests (SuperUser, SSCCE, SO checklist, Server Fault, recommendation), or suggesting another site (meta, superuser, tex, dba, sharepoint).  Regardless of the qualifications of the question I cited earlier, where's the option on the  "suggest it moves to another site" list to choose either a StackExchange site from a drop-down, or (preferably) just click a radio button for "let moderation figure it out, but it doesn't go here!"?


Communicating between Controller classes

We have two vf page and two controllers. What is the best way to allow these classes to share data between each other.  Example:   public class A {     public static DateTime dt{get;set;}     public  CSC_CommuncationController() {         dt = system.now();                 }     }  public class B{     public static DateTime dt{get;set;}     public B() {     system.debug('**'+A.dt);     } }   debug returns the blank value. can any one help on this. Note: We cant merge into single class as per requirement.

Bad effects of coiling electrical cables

I have a desktop computer and a lot of external hard disk cases. I coiled all cables to make them organized and easy to clean. But an electrician told me; if you are using a cable, coiling (wrapping) cables is wrong. It could damage your computer, electronic devices, etc. You should un-wrap cables of devices if you want to use them. So;  Are there any bad effects of coiling electrical cables?  Note: I found this on a Stack Exchange site, but still I'm not sure enough:   A quick answer that I learned; If cable is long and power usage will be high (up to 200 W), don't use a coiled cable. It melt and start a fire.


I recently studied about Cartesian products and I thought that I understood its concept, Until I ran into this expression:   If  $S=\emptyset$, $\ne\emptyset$,  then $S\times T = \emptyset$ .   Is an empty set the same as zero? in the sense that in nullifies a non empty set?  Thanks!

How much money do I need to generate $1500 per month in dividends for the rest of my life?

I am 29 years old. I do freelance work and I can save around $500/Month from that.  In my country, $1500/month is more than enough to cover all living/health/entertainment expenses for me and possibly for my future family and should be  the case for years.  I am 80% sure that $1500/Month will still be  enough for a family to live on in 2040. I don't care about the stock's value. I only care about living off  the dividends and never touching the principal. Maybe my kids will be able to live off it too.  I want to retire after I save the sum of money needed to generate $1500/month in dividends. My question is how much money is that?

Speed comparison between i = i + 1 and ++i

Is i = i + 1 faster than ++i for C++11?  that ++i is faster than i++ for classes, but not for simple types. Is there a similar comparison between i = i + 1 and these other two? Thanks!  EDIT 1: I use g++, but I'd be happy to know how this works on other compilers as well. EDIT 2: This question is different from  because it specifically asks about i = i + 1, as opposed to just talking about the difference between ++i and i++.  EDIT 3: (TonyD - grammatically edited by QuantumFool) The i = i + 1 aspect of the question is a duplicate of


The Cartesian product of an infinite number of sets each containing at least two elements is either empty or infinite?

In  it is written:     The Cartesian product of an infinite number of sets each containing at least two elements is either empty or infinite; if the axiom of choice holds, then it is infinite.   How can one prove that it is either empty or infinite?  My idea is that you assume it is finite but non-empty, and then consider its cartesian product with a set of at least two elements and come up with a contradiction, but I'm not sure exactly how.  Note that the definition of infinite is that for every natural number there is a subset that bijects to it.


How to pronounce to differ spatial from special?

It always bugged me that I do not know how to differentiate "spatial" from "special". I would just say "space" to be clear when "spatial" is the grammatically correct choice. Are the standard pronunciations different? If not, is there a way to indicate that I am saying either of the two?

Assume that $f$ is Riemann-integrable on the interval $[a,b]$ and $\epsilon$ is a positive number.    Prove that there exists a continuous function $g$ such that $\int_a^b|f-g| \lt \epsilon$ .    Note : The problem is the existence of the function. I don't know how to show it. Any hint or clue would be useful. An answer would be great.    Thanks in advance.


Has a "portfolio" of orthogonal projects ever been acceptable for a PhD thesis, instead of a single large project?

My interests are very broad. Before grad school I did a lot of things, but now it's expected that I only do one thing. Provided that I can demonstrate research competence in more than one field, by publishing for example, is it possible to write a thesis that consists of several smaller, orthogonal projects instead of a single great push? I understand why this isn't encouraged - diluting yourself is not an efficient way to get things done and it's unlikely that one would be able to become a PhD-level "expert" in more than one deep subject. But provided that one is very industrious and willing to give up the prospect of having any kind of normal life, which I am, has this ever been done?  Also: I realize this is funding-dependent - assume that I have external funding from a fellowship.


If I plan to get investments later, should I start a C Corp now? Or LLC then convert to C later?

Should I start an LLC then convert later once it is time for investments? Or just start as a C-Corp now?  At the moment what I have are open source software tools, and ideas on how to monetize them with products built on top of them, but it is going to take some time (months, maybe even more than a year) before any monetizable product is recognizable in terms of being implemented (unless investments can accelerate this).  But I think it would be great to have a business entity now, file trademarks/patents/etc, and be prepared, even if I am not making any money now. (Does it make sense to have an entity if not making money?)  I live in California, but hear I can incorporate in any state.

Is it possible to open my custom App from SAP BI App.


Prove $1+x$ is a unit in $R: \text{commutative ring}$ where $x$ is nilpotent  do I need to make use of a Taylor series expansion for this?  $(1+x)(1+x)^{-1} = 1 \implies (1+x)^{-1} = \displaystyle\frac{1}{1+x}$  and $x$ being nilpotent then for some positive integer n, $x^n=0$ I need to make use of this.   Or is there another way to do it?

Conjunctions of disjunctions equivalent to disjunctions of conjunctions?

For finite sets $I$, $J$ and formulas $A_{i, j}$ is this equivalence true?  $\bigwedge_{i\in I} \bigvee_{j\in J}A_{i, j} \equiv \bigvee_{j\in J}\bigwedge_{i\in I}A_{i, j} $  I tried it out with some examples and it seemed correct. How would prove that?


If $A^{2n}=I$, then $A^n=\pm I$ where $A\in M_n(\mathbb{R})$

Let $A\in M_n(\mathbb{R})$be a matrix. Then, if we have $A^{2n}=I$, can we say that $A^n=\pm I$?  I think yes, because the annihilating polynomial is $x^{2n}-1$. Therefore the characteristic polynomial should be one of $x^n-1$ or $x^n+1$. Thus, since the matrix consists of real numbers, therefore, the matrix $A^n=\pm I$. Am I wrong?Thanks beforehand.


I checked the grammar of my research article using a leading software. This is my sentence:   A total of 12.3 million sequences was used for the establishment of database.   The error is: 'Potential issues with passive voice usage'  Anything wrong here?  (NOTE: Er, the OP's question is about passive voice, but the "duplicate" linked thread is about subject-verb number agreement. Perhaps there's a related issue here, on subject-verb number agreement (which is debatable), but the OP's main question on passive voice ought to be addressed. Anyway, a short answer post here would probably be more appropriate than a related link. -- F.E.)

Javascript - Console.log does not log correctly

In console, of any web page, I do:  console.log(11111111111111111);  The result is: 11111111111111112  So I am really confused, trying to add 1s and see what happens:   111111111111111111 -> 111111111111111100 1111111111111111111 -> 1111111111111111200 11111111111111111111 -> 11111111111111110000 111111111111111111111 -> 111111111111111110000   Am I going crazy? What causes this to happen?  Is this intended? Is this a bug with Javascript?    Note: I am pretty sure it is not an integer overflow or something, because adding one 1 more goes to 1.1111111111111111e+21 which is correct.    This question differs from , because I am not asking about the limit of numbers that can be represented accurately, I am asking more like:  Why 11111111111111111 -> 11111111111111112 instead of 11111111111111111 -> 1.1111111111111111e+16 (scientific notation)


Is it kosher to ask a question that you plan to try to answer?

Possible Duplicates:             For instance, it occurred to me that the question "what's the difference between using 'sudo su - username' with and without a hyphen?" might be useful to others to have an answer to.  Is it okay to ask it myself and then answer it myself, so as to include the answer to that (or any other) question on these sites.  (I assume that one would be for superuser.)  It's possible that this question might already be answered on superuser.com, but that's not the point.  Substitute any example question you want: is it okay to answer your own questions, and even to ask them with the purpose of answering them.  The only reason not to do this, that I can see, are that some might perceive it as "gaming the system" to get more points.  But the reason for it is that it improves the supply of (hopefully) good questions and answers.  And I think the points would still be fairly earned.


Proof based problem in probability theory.

Consider a real random variable $X$ and a set $M$ included in $\mathbb{R}$ such that $$P(X=x)>0,\forall x\in M.$$ Demonstrate that the set $M$ is finite or countable.   We start by considering for all $n\geq 1$ the set  $$M_n=\{x\in M:P(X=x)\geq 1/n\}.$$ Then we have that  $$\underbrace{\frac{|M_n|}{n}\leq P(M_n)}_{\text{why is the inequality true?}}\leq P(M)\leq 1.$$ I am also not sure why $|M_n|<\infty?$ Perhaps someone can explain.  PS: Sorry for the previous post!


12.04LTS - could not open a connection to your authentication agent

I'm working on adding ssh authentication to a fresh Linode Ubuntu 12.04LTS deployment. I followed  to the letter up to the point where I need to ssh into the box with my now freshly added ssh key, but I instead get:  "Error: agent admitted failure to sign using the key"   Which is fine, the  says that all you need to do is to run  ssh-add   on the server and you'll be golden. Except when I do that I get   Could not open a connection to your authentication agent.   I double-checked the processes and indeed it does look like ssh-agent is already running (in fact twice, because I tried , which didn't work at all):  alex@mybox:~$ ps aux | grep ssh root      2645  0.0  0.1  49948   776 ?

How to show whether 3 planes have a common line of intersection

To show whether or not the 3 planes $$x+y-2z=5\tag 1$$  $$x-y+3z=6 \tag2$$  $$x+5y-12z=12 \tag 3$$ all have a common line of intersection.  Can I do $(3)-(2)$ to get the line $6y-15z=6$ and $(1)-(2)$ to get the line $2y-5z=-1$ which is $6y-15z=-3$ , and say that as these aren't the same line, they don't have a common line of intersection?  Another thing that is confusing me is that if instead of eliminating $x$, I chose to eliminate $z$, I would get different lines in terms of $x$ and $y$. But how can I get the equations of two different lines by eliminating from the same pair of plane equations? There's only one line of intersection between any pair of planes, so surely I should only be able to get one unique line if I eliminate a variable from a pair of planes?  Any help would be appreciated


How could Wolverine say he remembers everything?

At the end of X-Men: Days of Future Past, Professor X asks Wolverine what he remembers, and he replies "Everything".  However, the Trask incident happened in 1973 and the events of X-Men Origins: Wolverine happened after 1975.  It was shown in Origins that Stryker put adamantium inside his body and wiped his memory. Therefore, how could Wolverine say that he remembers everything that happened in 1973?  Kitty says only someone who time-travels remembers everything. Does this mean that Wolverine came from 1973 to 2023 directly, or did he live through those years again?

Subgroups of a cyclic group and their order.

Lemma $1.92$ in Rotman's textbook (Advanced Modern Algebra, second edition) states, Let $G = \langle a \rangle$ be a cyclic group. (i) Every subgroup $S$ of $G$ is cyclic. (ii) If $|G|=n$, then $G$ has a unique subgroup of order $d$ for each divisor $d$ of $n$.  I understand how every subgroup must be cyclic and that there must be a subgroup for each divisor of $d$. But how is that subgroup unique? I'm having trouble understanding this intuitively. For example, if we look at the cyclic subgroup $\Bbb{7}$, we know that there are $6$ elements of order $7$. So we have six different cyclic subgroups of order $7$, right? Thanks in advance.


I have got a script that should calculate the square root of 2, only it currently has 2 problems that I can't seem to solve. Firstly, the while loop does not stop, even when it should stop:  (This is the first few lines of the output when I run this script, the rest is just repeating the last 4 lines.)  sqrt:  1.5 sq:  2.25 sqrt:  1.41666666667 sq:  2.00694444444 sqrt:  1.41421568627 sq:  2.0000060073 sqrt:  1.41421356237 sq:  2.0 sqrt:  1.41421356237 sq:  2.0   Also, as the square root of 2 is an infinite number, I do not understand why it stops at 1.41421356237 and does not make a bigger number.  This is my code:  import time  def sq(inp):     a = float(inp)     return a * a  a = 2.0 b = 1 while sq(b) != 2.0:     b = (b + a / b) / 2     print 'sqrt: ', b     print 'sq: ', sq(b)     time.sleep(0.1) print 'Done!'   (I have put in a few extra bits to clarify, like the print 'Done' and the delay, but it does not change anything for me.)  Any help would be much appreciated. Thanks!


Surreal Trajectories in Bohmian Mechanics

In February of this year, articles started popping up describing the results reported in this paper by Mahler et al:   Taken from  article discussing the results, the following claims are related:     "Indeed, Steinberg and colleagues identified cases in which photon-1   begins on a trajectory from the lower slit, but then swerves upward   into a trajectory that appears to be from the upper slit. Using a   technique called quantum-state tomography, they were able to monitor   the polarization of photon-2 during this swerve, and saw its value   rotate from horizontal (indicating the lower slit) to vertical   (indicating the upper slit). As a result, a measurement on photon-2 at   the end of the trajectory gives the "wrong" slit."   While any theory that wants to be taken seriously as an alternative to Quantum Mechanics must agree with validated experimental predictions /results of QM (and indeed this study was done specifically to address predictions of BM that seemed at odds with QM), I'm having trouble seeing how the quoted series of measurements above can be reconciled with QM as I understand it.  Meaning:   A) My understanding of how QM would describe the above series of measurements is lacking (most likely)   or   B) the above series of measurements imply which-way knowledge while preserving interference can be demonstrated.  Which one of these seems to be the case, and can you help me view these results within the framework of classical QM (no pun intended)?    EDIT:   After reading the linked question marked duplicate, the answers do no address my specific question of how the authors claim to show which-way information while preserving interference is either erroneous, or in keeping with the validated postulates of QM.  Being peer-reviewed, I'd assume they (and their reviewers) at least believe they are on somewhat stable ground to make these claims.

Frattini subgroup $Φ ( G )$ is not trivial

Frattini subgroup $Φ ( G )$ of a group G is the intersection of all maximal subgroups of $G$. The question is  Let $G$ be an abelian group.What is the sufficient and necessary condition of $Φ ( G ) ≠｛e｝$？  I think if $G$ has no torsion part, we cannot say $Φ ( G ) ≠｛e｝$,because $\Bbb Z ×\Bbb Z×・・・ ×\Bbb Z$ has a maximal subgroup $p\Bbb Z ×\Bbb Z×・・・×\Bbb Z$, with intersectioning distinct primes, we gain just a trivial group. So, we need torsion part. But I cannot proceed from here.I only know the answer, $G$ has an element of order $p^2$, that  is, $G$ has theree subgroups. I want to deduce this consequence from steady discussion. P.S  According to this answer, in a ring that is a finite direct product of quotient rings of $\mathbf{Z}$, we can say rattini subgroup is the same as the Jacobson radical of the corresponding ring.


How do you force a line break between two words in a XAML-declared Label?

Maybe I'm not using the right key words, but all my searches are coming up empty. How do you force a line break?  I can tell you that none of the following work:  <Label     Content="Line&br;Break:" />  <Label     Content="Line<br />Break:" />  <Label     Content="Line     Break:" />  <Label     Content="Line\nBreak:" />   Can someone share this closely guarded secret?  Thanks.    EDIT:  Okay, never mind. I finally found it.  <Label     Content="Line&#x0a;Break:" />   Definitely not easy to guess!    EDIT 2:  Okay, and now to get the text to be right-justified, I went with this:  <Label>     <TextBlock         TextAlignment="Right"         Text="Line&#x0a;Break:" /> </Label>   Thanks to Julien for the idea of using a TextBlock.


How do I add a reference page as a text file?

I am really struggling with my References / Bibliography page. I will unfortunately be unable to give much of my code, as the contents of the document are unpublished. The template I was given to use for my code included a refs.txt file that had, \begin{thebibliography}{} \bibitem{}  \end{thebibliography}  Unfortunately, I used the APA citation style when manually citing in my document, so I do not want the number in the brackets ( [1] ) before my citation. I have a main.txt file that then includes my other text files, \include{ch1}        \include{ch2} \include{ch3}        \include{refs}  I believe it is due to this reason that the \usepackage{natbib} package continues to give me an error. Additionally, I have attempted to forgo the thebibliography aspect of my code and attempt to write a .bib file, but when adding it to my main.txt file, under my \include statements (while removing the \include{refs}, as either \printbibliography or \bibliography{example} it does not include my reference page at all. Is there anyway to fix this, or do something completely different, or will I have to redo all of my citations? Edit: I believe I have figured it out on my own.


is it normal to get significant lens flare with a 50mm f/1.8 prime lens?

I've purchased a Canon EF 50mm f/1.8 II. But I'm really disappointed in the results, especially when using it for night photography. :(  In my night shots a lot of lens flare appears in my photos. I've tried to change the angle and position of the camera to no avail. Also I cannot do any night photo without directing my camera to direct light like in street photography!  This photo was taken with my Canon 650D and 50mm 1.8 Lens in a long exposure night shot, and as you notice there is a bunch of lens flare in it. Some people suggested I remove the UV filter. This decreased the lens flare a little but there is still some flare in the photo .    I want to know if there is a problem with the lens? Or is this normal for a $100 lens? Does anyone else have a similar experience with this lens?


The following was marked as duplicate of the question , but I disagree:  the answers to that question all involve modifying the geometry or making derived geometries, and they deal with shading and transparency rather than fill patterns.  The question below clearly says those options have already been explored and do not do the trick.  I'm looking for a way that does not involve modifying the geometry or making derived geometries - let's face it, we're talking about a style here, not about ways to modify geometry - and is generic to any fill type or transparency level.  If this is still deemed a duplicate question, then the answer must be "no you can't do that as a style".  I'm new to arcgis but have been using qgis for a while.  Question on polygon styles in arcgis:  is there a way to make an 'inside buffer' outline or border style?  I know you can use the buffer tool to make an actual feature that is buffered by a number of geographical distance units, but for this case it would be much better to have a style that has a buffer (or halo) of a certain number of pixels regardless of zoom level, something like this quick hackjob in gimp:     solid line for the boundary of the polygon inside buffer or halo of a crosshatch pattern >>that does not rotate as a function of polygon outline angle at that point<< (I tried a marker line inside halo (offset by a negative number) and it looks fairly dorky due to rotation along the line) the rest is transparent   Can it be done?  Seems like this isn't that unusual of a thing to do.  Boundaries of all sorts are drawn this way on paper maps and they look quite nice.  Thanks in advance


have a list of lists such that the length of each inner list is either 1 or n (assume n > 1).  For example, I have a list named ""  >>> test= [['AA', 'aa'], ['BB', 'bb'], ['CC'],['DD','dd']]   On the end I will make list like this:  [('AA', 'BB', 'CC', 'DD'),   ('AA', 'BB', 'CC', 'dd'),   ('AA', 'bb', 'CC', 'DD'),   ('AA', 'bb', 'CC', 'dd'),   ('aa', 'BB', 'CC', 'DD'),   ('aa', 'BB', 'CC', 'dd'),   ('aa', 'bb', 'CC', 'DD'),   ('aa', 'bb', 'CC', 'dd')]   I try to solve this by use zip, but it seems impossible... Could anyone help me? Thanks very much.


Get the complete command line of a process

I can run taskmgr, Display, add column, select "command line", and I will see the complete command line of a process.  For what I check, this command line is quite long, and I can write it out (CTRL-C is ineffective). Is there a better way?


Recent patches for vulnerability attacks for SQL Server 2014 SP2 version

Keeping in mind the recent vulnerability attacks patches like Spectre and Meltdown , I would like to patch my SQL Server 2014 SP2 (12.0.5000)  1.Description of the security update for SQL Server 2014 SP2 CU10: January 16, 2018 - SP2 CU10   KB4057117  12.0.5571.0 2.Description of the security update for SQL Server 2014 SP2 GDR: January 16, 2018 - SP2 GDR   KB4057120  12.0.5214.6    Can anyone help me for below questions:   Recently we patched our Windows 2012 R2 Standard servers . Is OS Patching different from SQL Sever patching or these patches are already included during monthly OS patching installed ? Since we have both CU10 and GDR , should I apply both ? Which one should I need to first apply GDR or CU 10 ?

Unmet Dependencies for zsnes (works on one computer but not my other)

When I try (On Ubuntu 18.04.5 LTS) sudo apt install zsnes  I get the following Building dependency tree       Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

Can anyone point me in the right direction? I have 2 linux machines at home (2 laptops). One laptop has no problem installing zsnes but my other laptop just keeps giving me errors. Both my laptops are running Ubuntu 18.04.5 LTS so I don't understand why one computer with the same OS has no issue installing a program and the other one does. I tried the solution in here and it did not work  I've tried sudo apt --fix-broken install  and that did not fix the problem. I've also already run sudo apt update  and sudo apt upgrade  and yes even sudo dpkg --configure -a sudo apt clean sudo apt autoclean sudo apt -f install  and still the same issue.

14.04 LTS on HP EliteBook 8740w with NVIDIA and DreamColor

I have been running Ubuntu 13.04 for quite some time and though I would upgrade to 14.04 LTS as I also wanted to migrate to a larger SSD disk.  In the past it was tricky to install Ubuntu because the HP Dreamcolor display in my HP EliteBook 8740w needed the NVIDIA drivers. This was solved using an external monitor to install Ubuntu and then install the proprietary NVIDIA drivers.  When trying to install 14.04 LTS, this procedure doesn't work - all screens (VGA, Display-port and built in) remain black except for some funny coloured characters.  I though I could install the old 13.04 and then perform an upgrade. This has also proven to be tricky as "13.04 it is no longer supported" and a lot of references to packages doesn’t seem to be valid any more. I get 13.04 installed but have not managed to get the NVIDIA driver working. (It works beautifully on my existing installation (other hdd)).  Advice appreciated


Do the automatic success and failure rules apply to skill checks?

We had a rule check tonight that we couldn't answer. On the Pathfinder wiki I could only find info on natural 20s and 1s in regards to attack rolls and saves in combat.  Do they also apply to skill checks?

I use the scroll function with my mouse and it works fine. But either in script, or in terminal sections of Spyder, I can't use the touchpad for scrolling. I do not experience any problems with my touchpad in other programs like Word, Chrome etc. Is there any option for this in Spyder, specific for touchpad?  I am using Lenovo Legion Y520, Windows 10.


How to disable usb automount in Ubuntu 13.10?

This question has been already asked regarding Season 3, but if I recall correclty,  Riot stated something in the lines of "You can drop tiers in Season 4". So I want to know if this is the case, now that Season 4 has started..?  edit: Since some people obviously don't know that there is a difference between Season 3 (before December 2013) and Season 4 (from Mid January 2014), I want to state this clearly again: I am asking about dropping tiers in Season 4. This is not a duplicate to , since it was asked by the time of Season 3, which means through patches the system can be (and has) changed. So either the other question question (as well as the answers) has to be updated, or this question is just plain and simple not a duplicate.

Remove duplicates from a php array by a specific multi-dimensional array key that is nested

Just to let you guys know I tried a number of examples from Stackoverflow with no luck although this may look like a duplicate it's not.   I need to remove duplicate links from an array that have the same date. Duplicates links that do not have the same date should not be removed. Please have a look at the array. I would really appreciate if someone can help me out I'm stuck on this one.
