How to add my Blogger page to search engines?

I've written a short post on the blogger.com platform about 2 weeks ago. But I still can't find it on any of the search engines. (I've been searching by a specific phrase in it in double quotes.) I went to the  for my Google console and requested indexing of the page by its https: URL. I did it a few days back and received this:  But every time I check the Google console for that URL I see this:  What could be the reasons why it doesn't want to index it?

I need to create a custom Lightning component and inside of it I need to output record details page and related lists. There are standard components in App Builder for this: "Record Details" and "Related List - Single" but I can't find a way on how to add it to my component. How can I do this?


How to group(using set()) for every n elements in an array: python

I apologize if this question is already asked but i am not able to find the answer.  I have a list of elements. I wanted to group elements for every 4 elements in the array. Example:  my_list = ["A","B","C","D","E","F","G","H",....]  result = [{"A","B","C","D"},{"E","F","G","H"},....]


I have installed Ubuntu 13.10 (Desktop, 64Bit) on different machines. However, after installing the most recent version of Google Chrome browser and wine I do always get a mess with a lot of file type associations:   Folders and Archives -> Chrome Browser (results in again downloading them from disk) textfiles, TeX, ... -> Wine notepad png, jpg, ... -> Wine Internet Explorer pdf -> GIMP maybe some more   Meanwhile other file type associations stay correct:   odt, odp, ... -> LibreOffice eps -> Document Viewer most others   Is there a simple trick to tell Ubuntu to go back to default file type associations without searching for everything which fails and correcting it by hand?  Note: I haven't observe this behavior on the 32Bit version.


How to double singlequotes in a string using coldfusion or mssql (Replace not working and can't use cfparam)

I got a query containing this:  INNER JOIN  com ON com.company_id = pi.company_id AND com.company_name LIKE '%TUTTO PER L'UFFICIO%'   coldfusion show this error:      Incorrect syntax near 'UFFICIO'   How can I fix this?  P.S. can't use cfparam because this is not in a query(is in <cfsavecontent variable = "sql_query"> ... </cfsavecontent>)


What does it mean to say "Gravity is the weakest of the forces"?

I can understand that on small scales (within an atom/molecule), the other forces are much stronger, but on larger scales, it seems that gravity is a far stronger force; e.g. planets are held to the sun by gravity. So what does it mean to say that "gravity is the weakest of the forces" when in some cases, it seems far stronger?


Rack Mount Servers - Build them or Buy them?

This is the  for "Should I build coomputing hardware myself?" questions.   I have put together countless PCs, but never a large server. The geek in me says build it, but the realist in me says let the manufacturer handle it when there is a problem. Ignoring the time penalty involved with the initial assembly time of a built one, which is a better solution? Have you ever run into a problem with a home build server that would have been solved easier/quicker/cheaper by going with a manufacturer? Are there any features that manufacturers give that aren't easily attainable with a home built server?


I set $\lim_{x \to \infty} x^{1/x}=L$  What I tried is this:  $$\lim_{x \to \infty} \frac 1x \ln x=\ln L$$  $$\lim_{x \to \infty} \ln e^{\large \ln \frac 1x} \ln x=\ln L$$  We substitute in $e=\lim_{x \to \infty} (1+\frac 1x)^x$   $$\lim_{x \to \infty} \ln (1+\frac 1x) \ln x=\ln L$$  $$L= \lim_{x \to \infty} (1+\frac 1x)^{\ln x}$$  This looks a lot like the definition of $e$ and from here I think I could make an argument that $L=1$ because $\ln x$ increases slower than $ax$ for any $a$ after a certain point, but I would like to have a proof that is more direct. How should I proceed from here? Thanks.  P.S. No L'hopital's rule please


What are the differences between $\mathbb{R}^{k+m}$ and $\mathbb{R}^{k}×\mathbb{R}^{m}$

I am looking for help on how to export armatures and their animations in a custom export script.  I wish to have an animation format similar to BVH, i.e. a bunch of [Xposition Yposition Zposition] Xrotation Yrotation Zrotation for each bone for each keyframe.  Given the model (which exports fine using the bvh exporter), how does one get the keyframe data?  A long time searching the object tree of bpy has left me somewhat baffled.


Add path to $PATH if not already in $PATH

I need to add a path in a bash script, but it may be executed several times:  export PATH=${OPENSHIFT_HOMEDIR}/app-root/runtime/bin/:${PATH}   I don't want that path to be added over and over. How can I add it if it is not in $PATH yet?


So my device has an input of 5V 0.7A, but the cable isn't detachable from the plug so I need to use a different USB to micro-USB cable.  My power bank can output on 2 ports, DC 5V 1A and 5V 2.4A  If I plugged in the device to the 1A port, it should only draw 0.7A and not 1A right? And would the same go for the 2.4A port?  The device is a wireless charger, if that's relevant. I just want to make sure I don't fry my device or watch.


How do idle games handle such large numbers?

Just wondering how games such as Tap titans and Cookie Clicker handle such large numbers.  I am trying to implement an idle game however the largest number format supported by C# is decimal.

The arithmetic - geometric mean inequality states that $$\frac{x_1+ \ldots + x_n}{n} \geq \sqrt[n]{x_1 \cdots x_n}$$ I'm looking for some original proofs of this inequality. I can find the usual proofs on the internet but I was wondering if someone knew a proof that is unexpected in some way. e.g. can you link the theorem to some famous theorem, can you find a non-trivial geometric proof (I can find some of those), proofs that use theory that doesn't link to this inequality at first sight (e.g. differential equations …)?  Induction, backward induction, use of Jensen inequality, swapping terms, use of Lagrange multiplier, proof using thermodynamics (yeah, I know, it's rather some physical argument that this theorem might be true, not really a proof), convexity, … are some of the proofs I know.


Proof/Derivation of Residual Sum of Squares (Based on Introduction to Statistical Learning)

On page 19 of the textbook  (by James, Witten, Hastie and Tibshirani--it is freely downloadable on the web, and very good), the following is stated:  Consider a given estimate $$\hat{Y} = \hat{f}(x)$$ Assume for a moment that both $$\hat{f}, X$$ are fixed. Then, it is easy to show that: $$\mathrm{E}(Y - \hat{Y})^2 = \mathrm{E}[f(X) + \epsilon - \hat{f}(X)]^2$$ $$ = [f(X) - \hat{f}(X)]^2 + \mathrm{Var}(\epsilon)$$  It is further explained that the first term represents the reducible error, and the second term represents the irreducible error. I am not fully understanding how the authors arrive at this answer. I worked through the calculations as follows: $$\mathrm{E}(Y - \hat{Y})^2 = \mathrm{E}[f(X) + \epsilon - \hat{f}(X)]^2$$ This simplifies to $[f(X) - \hat{f}(X) + \mathrm{E}[\epsilon]]^2 = [f(X) - \hat{f}(X)]^2$ assuming that $\mathrm{E}[\epsilon] = 0$. Where is the $\mathrm{Var}(x)$ indicated in the text coming from? Any suggestions would be greatly appreciated.


Confusion about output lost in pipeline with perl

I want to ping a remote system, and have the date show up in my output, and then feed it along the pipeline to another program.  I used cat in my examples below only to be a simple example.  I can use the -D option of the ping command to include the unix timestamp, and I can use a quick perl command to convert that timestamp into a readable time.  But if I use perl to give me a easy to read time, it is somehow breaking the pipe, and the command I am sending the results to doesn't get anything.  When I use set -x and run the broken command perl seems to run first for some reason, but I don't understand why.  Broken  testip=8.8.8.8 echo trace $testip ping -W 1 -D -i 5 -t 3 -n $testip | perl -p -e 's/^\[([0-9.]+)\]/"[".localtime($1)."]"/e' | cat # No output  # Output with set -x + perl -p -e 's/^\[([0-9.]+)\]/"[".localtime($1)."]"/e' + ping -W 1 -D -i 5 -t 3 -n 8.8.8.8 + cat   But these work?  # working ping piping into cat testip=8.8.8.8 echo trace $testip ping -W 1 -D -i 5 -t 3 -n $testip | cat  # Output PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.

How to calculate stream order for vector data without a DEM?

I have a shapefile which contains the streams that were digitized from a satellite Image. I would like to calculate the stream order for this data. The data does not exactly match the DEM that I have, since the satellite image was of much higher resolution.  Is there any arcscript, code or readymade tool which I could use to calculate the stream orders?  I have Arcgis 10 with spatial & 3D analyst, as well as QGIS.

Using keyword "this"in the definitions file

I am trying to learn c++. So I started creating a simple class Linked List. From what I understood you should put all the methods/contructors declarations in the .h file. But after I have done that I have encountered a problem, while creating the method prepend. How do I use the keyword this in the definitions file (.cpp):   Header File  #ifndef LIST_LIST_H #define LIST_LIST_H  template <class T> class List { public:     List(T data, List tail): data(data), tail(tail) {}     List prepend(T data);     List get(int i);  private:     List tail;     T data; };  #endif //LIST_LIST_H   Implementation File  #include "List.h"  template <class T> List::List(T data, List tail): data(data), tail(tail) {}  template <class T> List List::prepend(T data) {     return new List(data, this); }   I tried searching for the solution but since I am new to c++ I don't know how to search it.


Comparing a string with the empty string (Java)

I have a question about comparing a string with the empty string in Java. Is there a difference, if I compare a string with the empty string with == or equals? For example:  String s1 = "hi";  if (s1 == "")   or   if (s1.equals(""))    I know that one should compare strings (and objects in general) with equals, and not ==, but I am wondering whether it matters for the empty string.


I posted this question earlier but I like to repeat it again.  I have 50 folders. Each folder consists of 40 rasters. Each raster has a value that I need to extract. These rasters share the same x&y. Finally, I need to put them all in one data frame. To do so, I tried to run a loop to read all rasters from all folders and combine them by row. For example, I have 50 Rain rasters, so these will fall under the same column and so on. Is there any way to do that?  Here are the codes:  Reading <- function(raster) {   df <- stack(raster) }  All_raster <- dir("E:/50_folders/", recursive=TRUE, full.names=TRUE, pattern=".tif$")# This is to read rasters from 50 folders All_tif <- sapply(All_raster, Reading) ALl_tif <- as.data.frame(All_tif , xy =TRUE)   And this is the error I get Error in as.data.frame.default(x[[i]], optional = TRUE) :    cannot coerce class ‘structure("RasterStack", package = "raster")’ to a data.frame


How can I get boot menu after Ubuntu installation?

I would like to thank you for taking the time to read this.  My problem: I tried to install Ubuntu 12.04.4 LTS on a system in my Lab but after the installation when I restarted the system it booted straight to Windows. I restarted it many times but I did not get a boot option to load Ubuntu. During the installation I do remember the installer showing that it was installing GRUB so I want to know how I can boot to Ubuntu.  The system I used has Windows 7 Enterprise edition. I created 100 GB partition (/dev/sda6) and a 5GB swap partition (/dev/sda7) before installing Ubuntu in the 100 GB partition. I chose /dev/sda for boot loader installation. Before installation I noticed that there already was a 26 GB ext4 partition so I am guessing that someone had previously tried installing Linux on this system. Anyway I needed more space so I carried out my installation in the 100GB partition.  I have tried all different boot orders possible in the BIOS, I have tried re-formatting and re-installing Ubuntu but it still boots into Windows directly. In windows, System and security → System → Advanced system settings → Advanced → Startup & Recovery → Settings:  lists Windows 7 as the default OS and doesn't give me a choice to select Ubuntu in the drop down menu.  I have tried the recommended repair in boot-repair but it gives me an error:  Boot repair: Please open a terminal and type this: sudo chroot "/mnt/boot-sav/sda6" dpkg --configure -a sudo chroot "/mnt/boot-sav/sda6" apt-get install -fy sudo chroot "/mnt/boot-sav/sda6" apt-get purge -y --force-yes grub* shim-signed   I type them but nothing seems to happen.

Automatic sorting system. (Hoppers moves 64 blocks, instead of 1 at the time)

I'm playing on a server where hoppers move one stack of items at a time, instead of just 1 item. I want to make a sorting system, but because of changes to hopper mechanics, normal sorting systems don't work. I've tried asking friends and other people on the server, and looking up different tutorials, but every time, I find the same problem. Hope someone in here can help me. If you have any questions or need further details, i will answer/provide them, as good as i can!

Can any ally benefit from the help action during a combat turn?

Party members Alex, Bart, and Caroline are in combat with a Drow, in that turn order (A, B, C, D).   Alex uses the help action on the Drow, being within 5ft.  If Bart chooses not to attack on her turn, can Caroline attack with advantage because of Help?  If Bart decided to attack, would Bart have gotten advantage instead?  Does a specific ally need to be named to benefit from the advantage?  Or is it first-to-attack?

Why are flights from some countries much cheaper than others?

I live in Resistencia, about 350Km away from Asuncion, the capital of Paraguay. And about 1000Km away from Buenos Aires, the capital of Argentina, my own country.  Let's assume I want  to go to Miami.  If I search flights originating from my city, most travel websites (Google Flights, Despegar, etc) will try to sell me tickets from Resistencia to Buenos Aires, and then to Miami. This will end up costing me 27.000 Argentine pesos. Usually this includes flights from Aerolinas Argentinas only, as it seems to be the lowest priced airline. The trip to Buenos Aires is usually 2000-2500 pesos for both tickets. So the bulk of the pricing is the international flight.  Instead, if I search for flights to Miami from Asuncion, Paraguay, I also get two flights (usually stopping in Lima or Panama), but the price is actually as low as 12.000 Pesos. There are no flights to Asuncion but it's a 5-6 hour bus ride.   Why is this difference so HUGE? I think maybe because the Aerolineas flight is a direct flight, and the others make a stop somewhere else.  Edit: this is, I think, a diffrent question from  because that one explains about "fine" pricing by airlines, simulations, etc. I don't think this is related, because that fine pricing is usually a few % points. This is a whooping 50% difference. There must be something different going on.


Is it OK to prolong a non-significant A/B test?

Background: We know from  that ending an A/B test early due to "significant" results is a mistake.  Question: But what about when a test runs for the desired time period and shows insignificant results – is it fine to prolong it? What are the risks?  Note: It would be great with a simple mathematical example of any risks, similar to the example in that linked article.  I have only a basic knowledge of probability theory and maths, so I would appreciate an answer I can understand with that knowledge.  Attempt: My intuition is that it could be problematic, because you had an experiment with a calculated reliability (will show false positives in X% and false negatives in Y% of such experiments), but now you're effectively waiting indefinitely for the first true-positive or false-positive significance.   So I should think you get more false positives than you accounted for when setting up the original experiment. But presumably the likelihood of false positives also decreases as we get more data.

I have a question. What's the difference between atan and atan2 in JavaScript?  I want to figure out the angle between the vector V (-1, 0) and the axis.  When I called the method atan(0 / -1), the answer was -0 rad. When I called the method atan2(0, -1), the answer was Pi rad.  Why do they have different answers?  Also, the answer I was expecting to get was Pi rad, so since I was using atan in my code, it kinda took me a while until I tried atan2 and it finally worked (to my surprise!)  Thanks in advance! ^_^

How many bitstrings of length $n = 10$ contain at least $k = 3$ consecutive 1’s?

I'm working on this problem and am having some difficulties.  I know something important to keep in mind is that (as an example)  $1110001111$ is just one bit string despite it having two individual substrings with at least 3 consecutive ones.   I know there are $2^{10} = 1024$ total possible bit strings of length $n = 10$. We want to find the number of bit strings that contain at least $3$ consecutive ones.  I start by first counting the number of bit strings that contain $3$ consecutive ones.  There are ${10}\choose{3}$ possible ways to insert three ones in this bit string of length $10$, but that isn't what we want, we want to count the number of ways to have three consecutive ones in a bit string of length $10$. And this is where I'm getting stuck.   To solve this problem, I started with trying by exhaustively listing out the total possible strings, but quickly started to run into some problems and thought there was a more efficient way to do it. So then I was thinking about using the inclusion-exclusion principle, where my sets would be something like "$A_{1}$ is the set containing three consecutive ones; $A_{2}$ is the set containing four consecutive ones,..., $A_{10}$ is the set containing $10$ consecutive ones" but then I realized this would be a truly ginormous computation and that there must still be a better way to go about solving it.  So my question, is how to I count the number of bit strings of length $n = 10$ where I have at least $3 \leq k \leq 10$ consecutive ones?


Why and when should eval use be avoided in shell scripts?

Many answers and comments on this site mention that one should generally avoid using eval in shell scripts.  Often these comments are addressed to beginners.  I've seen mention of security issues and robustness, but very few examples.  I already understand .  However, the answers given there only mention briefly the dangers of using eval.  Remarkably, every answer notes that eval can be a major security hole, but most only mention this fact as a concluding sentence with no elaboration.  This seems worthy of further consideration and is really its own question.  Why is using eval a bad idea?  When would it be appropriate to use?  Are there any guidelines by which it can be used with complete and total safety, or is it always and inevitably a security hole?    EDIT:  is the sort of canonical reference (answer) I was actually looking for when I posted this question.  Anyone abusing eval can be pointed to this reference.


How to Intall Linksys Wifi Adapter Driver on Dual boot Ubuntu

Ubuntu 20.04 I just installed Ubuntu, dual boot with Windows 10 on a desktop. Due to circumstances, I cannot use Ethernet cables and so I bought a WiFi adapter: Linksys AC1200, WUSB6300, 1030.38.712.2019. On Windows, the adapter worked without even having to use the CD setup .exe it came with. However, Ubuntu can't seem to detect the the device. I read another post  on how to download the driver file on Windows and then transfer it to Linux. The problem : I can't seem to find a driver file of the appropriate version on the official website nor do I know what to download or install. According to some posts, one can install or download from GitHub but, it seems like there aren't any installation methods other than with internet.


Temperature is a measure of kinetic energy transferred to particles, henceforth,  being vacuum, temperature cannot be measured. But then, there is cosmic background radiation. It is the leftover heat from the Big Bang, but then heat in space doesn't make sense, how does this radiation, heat up space time when it technically cannot be heated up? Moreover why is it referred to as heat when it is approximately just $2.5$ Kelvin, which is just above absolute zero?


Why is the pressure on the ground equal to the weight of the atmospheric column on it? On the table top, the coins are stacked together, and the pressure on the table top is equal to the weight of the coin column, because the coins are in contact with each other. The atmospheric molecules are not in contact with each other. There is a large space between them. How can the pressure on the ground equal the weight of the atmospheric column? Is there any experimental proof?


Can we disconnect an object from the pull of gravity using some material?

I have once come across a material/ substance/ compound,  or something, that cuts off objects from Earth's gravitational pull.    In other words, it would keep the object suspended in the air and will not allow it to touch the ground, hence, we can say that this is a barrier between the object and the earth's gravity.   Can you please give me the name and properties of this material / substance / compound / gas / or what ever it is?

For example, the position of 2nd "OU=" in the string?  How to resolve this issue?


I have seen many explanations for why the net electric field inside of a conductor is zero (assuming only electrical forces are acting on the particles inside of it). These explanations typically say that the charges in the conductor will move the outside and, to ensure that they remain stationary, there must be a net electric field of zero everywhere inside of the conductor. There seems to me to be a very large disconnect in this logic. If all of the charges are on the surface, then yes, I understand that the electric field near the surface of the conductor must be zero, but why does it have to be zero at, say, the center of the conductor (where there are presumably no charges).


How to scroll in a terminal using keyboard?

How can I scroll in bash using only the keyboard? If it's not possible in bash, are there any other shells that support this?


I know  is actually trying to be helpful by formatting code, but it appears that the first line of code is always indented incorrectly (maybe it's just my OCD). After about three of their edited posts corrections, which somehow always got approved, I ended up going through just the first page of approved edits this user made, and corrected the same problem.   I don't think it would be correct to add a comment directed at the editor asking them to correct this issue. I don't see any way to flag a user for moderator review, or have the moderator contact them. I don't see a method to flag an edit for review. and I don't see any other way to contact this user to help them correct the problem and save a lot of people extra work.   What is the solution to this?

Display polygon colours as percent reflectance of sunlight

I have a set of polygons which I would like to display in different colours.  The only information I can give on the colours is the percent reflectance of sunlight in different channels, e.g.:  B:  0.45 - 0.51µm, 5.1%  G:  0.53 - 0.59µm, 7.2%  R:  0.64 - 0.67µm, 6.1%  NIR:0.85 - 0.88µm, 38.7%  (Landsat 8 OLI channels)  Is there any chance that I can get an RBG or CIR composite, when the values are stored like this in the attribute table of a shapefile?


What is the differece between .com and .in in SEO

I am starting an e-commerce website for local customers and the .com I want for the website has been taken (however the .in is available).  I want to know whether it is going to affect my SEO rankings or not if I use .in.  I want to expand the website for other countries too in the future.


I know the definition of prime number when dealing with integers, but I can't understand why the following definition also works:     A prime is a quantity $p$ such that whenever $p$ is a factor of some product $a\cdot b$, then either $p$ is a factor of $a$ or $p$ is a factor of $b$.   For example, take $4$ (which clearly is not a prime): it is a factor of $16=8\cdot 2$, so I should check that either $4\mid 8$ or $4\mid 2$. But $4\mid 8$ is true. So $4$ is a prime, which is absurd.  Please note that English is not my first language, so I may have easily misunderstood the above definition.  Edit: Let me try formalize the definition as I understood it: $p$ is prime if and only if $\exists a\exists b(p\mid a\cdot b)\rightarrow p\mid a\lor p\mid b$.


Bug with biber 2.15 under Windows with large bib-files

I just updated my MikTeX distribution and am now running biber 2.15 with biblatex 3.15a. And all of a sudden, I run into problems. I have a bib-file with 1888 entries, and trying to use that now seems to break biblatex, although it worked fine on earlier versions. I do not know if the problem lies with biber or biblatex, but try the following: I created two bib-files out of my original one, available  and . With the following MWE it works fine and both citations are resolved: \documentclass{article} \usepackage[french, german, UKenglish]{babel} \usepackage[backend=biber, style=authoryear]{biblatex} \addbibresource{Test.bib} \addbibresource{Test2.bib}  \begin{document} Let's test: \textcite{Arnold2002}, \textcite{Setty1973}  \printbibliography \end{document}  However, when I combine both bib-files into one and try to compile with that, none of the citations is resolved. Since it works fine when having the database split in two, I cannot see any other reason for this behaviour other than the new biber or biblatex having a limit of file-size/entry-number in the bib-file. Not the amount of entries actually cited, mind you (as it was in bibtex), but the sheer number of entries in the database. Or do I overlook something? Any help would be greatly appreciated. EDIT 1: Here is the .blg-file. Indeed, there is an error message "[1095]", but I cannot make sense of it: [0] Config.pm:312> INFO - This is Biber 2.15 (beta) [0] Config.pm:315> INFO - Logfile is 'DatabaseTest.blg' [311] biber-MSWIN64:330> INFO - ===  [385] Biber.pm:415> INFO - Reading 'DatabaseTest.bcf' [882] Biber.pm:952> INFO - Found 2 citekeys in bib section 0 [998] Biber.pm:4334> INFO - Processing section 0 [1068] Biber.pm:4523> INFO - Looking for bibtex format file 'TestFull.bib' for section 0 [1095] Utils.pm:411> ERROR - Data file 'TestFull.bib' cannot be read in encoding 'utf8': Wide character at C:\Users\Manue\AppData\Local\Temp\par-4d616e7565\cache-b32225defac3568d1e921af5a7245ca571b236aa\inc\lib/Win32/Unicode/File.pm line 163. [1095] Biber.pm:132> INFO - ERRORS: 1  EDIT 2: I now identified the limit length. The file available  contains as many entries as I manage to process. It contains 1477 entries, 25026 lines, and 1,048,339 bytes. This file just works, but as soon as I add just one more mock entry like @Article{Test3,   author       = {Author, A. and Author B. and Author, C.},   date         = {2020},   journaltitle = {A Journal},   title        = {A nice title of a certain topic which I cannot even imagine},   issue        = {3},   pages        = {1--18},   volume       = {12} }  I get the same error as above. This seems to be the length limit with which biblatex works properly. EDIT 3:  is the full file that does not work directly from JabRef (as .bib) without any changes. And  is the same file as hex dump exported with Cygwin.

My original objective was to find the arc length of $\sin x$ on the interval $[0, 2\pi ]$. Of course the traditional way to calculate arc length is to use the formula: $$L = \int_a^b \sqrt{1 + (f'(x))^2} dx$$. And so obviously the formula becomes in this case: $$\int_{0}^{2\pi} \sqrt{1 + \cos^2 x} \ dx$$ But I am stuck here. Does anyone know of any analytical methods to anti-differentiate $\sqrt{1 + \cos^2 x}$, if any exist at all?

Man undergoes radical surgery to research aliens

I'm trying to remember the title of a story i read where a man is hired to research primitive aliens by being altered surgically or genetically to live as one of them. The only catch is he can never go back to being human. After several different body changes, the main character is told he can be modified one last time, and he can pick what he wants. He chooses to become a being with the best aspects of all the different aliens he experienced.

Prove that an infinite chain of proper containments of compact sets is non empty

I need to prove that if $K_1\supset K_2 \supset K_3 \supset K_4 \supset \ldots$ is a chain of proper containments and each $K_{i}\subseteq \mathbb{R}^{n}$ is compact, then $\bigcap_{i=1}^{\infty} K_{i} \neq \emptyset$.  I understand that $K_i \neq \emptyset, \forall i$ because of the proper subset condition and since the empty set has no proper subsets.   I also understand that the compact condition is necessary in order to prevent sets that limit, at infinity, to an empty set but for no $i$ are empty themselves (example: $K_i=(0, 1/i)$).   However, I'm not sure how to complete.


What are the legal implications of creators streaming their development?

Is there any question of losing ownership of their work if people stream themselves coding? I can understand that streaming modeling, animations, and game design would be fine because even if you see someone do it it will take time to do, but what about code?  Are there worries about other people recording their streams and using their code? Is there some special case for these games like being open source or non proprietary?


How to add elements of a list by element to a tuple?

I'm trying to take a list in python and append (in a tuple) a few variables and also in the tuple add every item from another list, so that each individual item in the list has it's own place in the tuple.  Basically adding more elements to a tuple, from another list.  I tried running a for loop inside the tuple but of course that didn't work. I've seen someone do something similar but not sure how it actually works.  items = [] listy = [] var1, var2, var3 = 0, 1, 2 items.append((var1, var2, var3, for l in listy))   I just get an invalid syntax error. Again, this is just a visualization of what I want to happen. Here is another example of how I see it looking:  list[var1, var2, var3, listy[0], listy[1], listy[n]]   Thanks for your input. Sorry if this is a stupid question, I haven't been using python too long but couldn't find anything specific online.

Are there any gotchas with using two Apple IDs for one user in the App Store?

To date I have had an Apple ID tied to my personal email address. It uses my personal paypal account for the purchases, and currently it has a credit balance thanks to some Christmas iTunes gift cards.  With the App Store recently being released, I'd like to buy an OS X app for business purposes. I don't want to use the credit balance on my personal Apple ID account, so I was thinking about creating a new Apple ID just for when I buy apps that I use for business. This way I could have the business Apple ID tied to my business paypal account.  However, I'm concerned that there might be some gotchas with using two different Apple IDs on the same MacBook by the same user. Before I just try this blindly, does anyone have any experience or know of any gotchas?

Sum of infinite series $\sum_{i=1}^{\infty} \frac 1 {i(i+1)(i+2)...(i+n)}$

Lets define the following series $$S_n =\sum_{i=1}^{\infty} \frac 1 {i(i+1)(i+2)...(i+n)}.$$ I know that $S_0$ does not converge so let's suppose $n \in N$ and define $S_n$ for some $n$. We have $S_1=1$ , $S_2=\frac1 4$ , $S_3=\frac 1 {18}$ , $S_4=\frac 1{96}$ , $S_5=\frac 1{600}$ etc.. the numerator in all results is 1the pattern in denominator is $[1,4,1,96,600...]$ and   that is equal to $n*n!$ Finally I want to prove the general equality: $\sum_{i=1}^{\infty} \frac 1 {i(i+1)(i+2)...(i+n)}=\frac 1 {n*n!}$


Including calling conventions in function declarations

I am reading about Win32 programming with C/C++ and came across a page which defines the WinMain as:  int WINAPI wWinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PWSTR pCmdLine, int nCmdShow);   I understand most of this, except I do not understand where did the part WINAPI come from?  I know that this is a macro for a calling convention. That's not what I am seeking clarity on. My question is not on calling conventions.  When I look at Microsoft's documentation on , and I read through optional parts of a function declaration, I don't see any mention of including a calling convention at any place in the function declaration. So where exactly does Microsoft in their documentation speak about including calling conventions in a function declaration?


What does it mean when a C++ file has .cpp.hpp at the end of the filename?

This question has nothing to with why C++ has header files, or what extensions are commonly used for header files.  Why would a file have both ".cpp" and ".hpp" in the name?  For example,  example.cpp.hpp   Sorry if the answer seems obvious or easily searched, but I've looked through a number of different search engines and can't find anything.

The right way to define a custom object properties?

I am currently defining custom object properties as follows:  private int count; public int Count {     get { return count; }     set { Count = value; } }   my fist part of the question is there any difference between defining fields like that and like:  private int count; public int Count {get; set;}   unless you want to check something about the value as so:  private int count; public int Count {     get { return count; }     set     {         if (value >= 0)         {             count = value;;         }         else MessageBox.Show("Value is negative", "Error", MessageBoxButton.OK, MessageBoxImage.Error);     } }   And the second part is is there a better way of defining object properties in C#?


General rule for partial fraction decomposition

I am looking for a general rule to be able to decompose into partial fractions all expressions of the form:  $\frac{P(x)}{Q(x)}$  where $P(x)$ is a polynomial of degree $p$, and $Q(x)$ is a polynomial of degree $q$, such that $p<q$ $\forall$ $\{p, q\} \subset \mathbb{N}$  An attempt at doing this is already  but it is not a general rule, more a collection of cases.

Writing data to new database - collation question

We will be changing the collation of our databases in a few months. I am setting up an environment, to test the new collation with my application.  I have created a database with our new collation and want to write data into the new database.  Database1: SQL_Latin1_General_CP1_CI_AS Database2: Latin1_General_CP1_CI_AS_WS    If I run the following query:  INSERT INTO Database2.table1 SELECT * FROM Database1.table1   ...will SQL use the collation of Database2 or Database1 to write the data?  Both databases are on SQL Server 2012.  The collation for Database2 is Latin1_General_CP1_AS_WS

Can a Sorcerer Gain Additional Spells Known with Magic Initiate?

The Magic Initiate feat states:     Choose a class: bard, cleric, druid, sorcerer, warlock, or wizard. You   learn two cantrips of your choice from that class's spell list.      In addition, choose one 1st-level spell from that same list. You learn   that spell and can cast it at its lowest level. Once you cast it, you   must finish a long rest before you can cast it again using this feat.   Assume a character is a 4th level sorcerer, elects to take this feat, and chooses Sorcerer. Per the feat, they now 'learn that spell'. Also they can cast the spell for free once per day using the feat, but can they continue to cast the spell using their spell slots?  Additionally, can they replace that spell when they reach 5th level as a sorcerer per the Spells Known feature?:     Additionally, when you gain a level in this class, you can choose one   of the sorcerer spells you know and replace it with another spell from   the sorcerer spell list, which also must be of a level for which you   have spell slots.


Prove that sinx/x uniformly continuous at x [1; infinity) by using epsilon delta

Picking numbers without picking neighbours

In how many ways can I choose 7 integers between 1 and 48, so that I never pick any neighbouring numbers (like 23 and 24)? I am looking for a good way to attack this problem. I have a strong feeling that the problem would become easier if I said that 1 and 48 were neighbours. I would get rid of boundary problems, when I count. Using the inclusion-exclusion principle seems an idea, but I haven't found the right way.  Thx in advance,  Jschmidt


Annoying lock screen timeout in Windows 8 64 bits (no pro). How to configure it?

I don't know why or when it started. I just noticed that the laptop where I have Windows 8 has an absurdly short timeout to lock the screen. The screen that is shown is the picture of the current user prompting for password.  I have tried many things in an attempt to get rid of it. Note that this version of Windows 8 is not Pro or Enterprise and It does not have the gpedit.msc tool:   In the screen options, in screensaver, no screen saver is set, but the timeout field steel controls when the screen will be locked or turned off, so I set value 0 there, and it changes to the string "(Never)". Also I unchecked "prompt for password". But screen steel locks.  Googling I found that there is a policy, editable in gpedit (no available in this edition of Windows), to set the timeout to lock the screen. Then I looked for the registry key that sets that policy and changed it (but it seems that it has no effect at all, screen still locks with a timeout of 1 min approx). The key I edited is "HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System\InactivityTimeoutSecs". I didn't existed, so I created It as DWORD with a large value.   Machine is SAMSUNG ATIV Book 2, in case somebody knows of any software that comes by default that may be causing this. I uninstalled the trial security software and I'm using Windows alone with Windows Defender and my common sense.


I'm having quite hard time proving the following statement: $$\lim_{n\to\infty}\sqrt[n]{2^n-n^2}=2$$  I though about using the squeeze theorem. So I started to look for upper and lower expressions and quickly found an upper limit to the expression,  $$\sqrt[n]{2^n-n^2}<\sqrt[n]{2^n}=2$$  However, I found it very difficult to find the lower limit. Help would be appreciated!.


I tried to follow the new Blender 2.8 tutorial from Blender Guru.   When entering "Sculpting" with the icing there were suddenly alot of holes in it. Why is this?


I rooted my Dream/G1 last night and finally gave up on modding it (not for good mind you, but for the moment) and opted instead to just restore it to factory settings via Settings > SD card & phone storage > Factory data reset, which did solve all the problems I was having with multitasking (and not being able to answer it, etc.)  Curiously, I still seem to have root on the phone, despite having reset it. I'd love to understand how that is possible! Superuser Permissions is the only non-stock app still on the phone, and I'm still able to use su to gain root privileges from adb shell. Is this because BusyBox installs to my SD Card?  My phone works just fine, so this is hardly critical, but the whole exercise was/is about knowing my phone better and this is most def. a mystery. Thanks!


SWR surname that in fact describes or applies to the human in question?

There are (in real life) many amazing examples of this (Bill Gates, "gates" being the fundament of computers, Tiger "Woods", the greatest ever user of "woods" golf-clubs, etc) and it is a staple of fiction.  Is there a single-word for this, or a frequently-used term?  Note that in fictional usage, I observe there is literal "X", so, for example I just saw a children's movie where "Madame Work" was a taskmaster. However, authors often employ near-literal "X": for example, most of the minor character surnames in Harry Potter are 'kind of" "X".  So, is there an "X" for Bill "Gates", Tiger "Woods", an undertaken named Mr. Death, etc?  Sorry if this has been asked already, I couldn't find it.    Note - I've just found there's a "wikipedia" page claiming 'aptonym' or 'euonym' is sometimes used.  Wikipedia is often valueless, so I do not know if this is a meaningful claim.


How to restrict accès to pre- installed apps, in. Big Sur?

I actually want to restrict access to distraction ( tv app, FaceTime, App Store) and I was able to do that without any problem in Catalina.. but with Big Sur it's another story I have already tried using screen time but I don't think parental control is the solution to my problem.

Why moments of expectation are known as “moments”

I am studying moments of expectation, and seen the formulas for computing the moments. There is one thing I am not clear of, and not getting answer for that.  Why moments are named as moments? To my understanding, the word "moment" has relationship with time, so what is the role of time in computing expectation moments?

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the general theory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the large-scale structure of the universe.[6] \begin{figure} \centering \includegraphics[scale=0.60]{333.png} % d3.png: 900x400 pixel, 72dpi, 31.19x14.29 cm, bb=0 0 884 405 \caption{ MSCI Sector performances.} \label{Fig:16} \end{figure}   \end{document}   I want to switch from portrait to landscape page orientation.

Below is a problem I've been thinking about - it is a textbook problem:  Find the many roots the equation $$2z^4-3z^3+3z^2-z+1=0$$ has in the right half-plane $\Re z>0$  I have two thoughts: use Rouche's Thm directly using "large" semicircle, and using the Cayley transform to convert the question to "How many zeros are in the unit disk?" and then use Rouche's Thm. However, when I do this it doesn't work out as nice as I expect and I think I may be missing the intended solution.


How do I format a String in an email so Outlook will print the line breaks?

I'm trying to send an email in Java but when I read the body of the email in Outlook, it's gotten rid of all my linebreaks. I'm putting \n at the ends of the lines but is there something special I need to do other than that? The receivers are always going to be using Outlook.   I found a page on microsoft.com that says there's a 'Remove line breaks' "feature" in Outlook so does this mean there's no solution to get around that other than un-checking that setting?  Thanks

Is there a convention for the polarity of voltage specified as \$V_{XY}\$?

Inspired by , which includes the image:    Which solicited the comment:     No, you have the polarity of Vce shown backwards in the diagram [...]   The diagram seems consistent to me: the arrows go from the thing in the 2nd letter of the subscript, to the 1st letter of the subscript, in each case.  We might see similarly subscripted voltages in contexts besides BJTs: we also see them in FETs, or things that might not be transistors. Thus, given an arbitrary \$V_{XY}\$ to measure, the procedure is:   place positive lead of voltmeter on X place negative lead of voltmeter on Y read measurement   Is this always the convention? Is it a more explicit definition? Or does it change, based on the thing in question, or even which part of the thing being discussed?

I made a png file in Photoshop that only has R/G/B/A channel like this:  Then I'm going to use this as my texture in Blender in shader editor:  The final result is like this all black, where the text should've been in the red area,because I only unwrapped the center face   Why is mesh all black, even the left corner dots that represents all the rest faces, are black, the area in the texture is transparent, did blender treat transparent area as Black? The Png image doesn't have Alpha channel, only R/G/B, can some one help me to understand。 Edit:This is my original image,with only R/G/B channel, no Alpha channel, you can check how it looks in Photoshop from above checkerboard screen shot, the background is transparent, though no Alpha channel, no 4Th channel, it 's transparent and I suppose the RGB for the transparent is NULL, I'm not sure if transparent pixel can be R:null,G:null,B:null, if you know what I mean, it is common to control by using Alpha channel, but Photoshop can save transparent as NO RGB VALUE

Strict warning: Only variables should be passed by reference in Open Restaurant

I installed  based on Drupal 7.x.  As soon as I insert any menu item into create categories, I get this warning:     Strict warning: Only variables should be passed by reference in sizzle_preprocess_views_view__content__menus__all_menus() (line 69 of /web/htdocs/xxxxxxxxxxx/home/profiles/restaurant/themes/sizzle/includes/menu.inc).   I checked the line and I got this code:  // Render the category and add it to template. $variables['term'] = drupal_render(taxonomy_term_view($term, $view_mode));   I don't know how to improve this, in order to solve the issue. Writing to the group that made Open Restaurant I didn't got any answer. Hence my post here.


Showing that an integral domain is a PID if it satisfies two conditions

This is just a textbook problem from Dummit and Foote, but the issue is that our class barely touched on PIDs and the preceding material, so I don't really know or understand much.  Anyway,     Let $R$ be an integral domain.  If $R$ satisfies the following:           i. any two nonzero $a,b \in R$ have a gcd in the form of $d=ra+sb, r,s \in R$          ii. If $a_1, a_2,...$ are nonzero in $R$ such that $a_{i+1}$ divides $a_i$ for every $i$ then $\exists N \in \mathbb{Z}$ such that $a_n$ is an unit times $a_N$  $\forall n \ge N$,          prove that $R$ is a principal ideal domain.   From what I've gathered, the second condition means that $(a_1) \subset (a_2) \subset...$ and $(a_N) = (a_n)$ $\forall n \ge N$.  However, I'm not sure what I should do now. I'm worried that I'm lacking the necessary context here especially since we used Artin pretty much all semester.  In short, my question is: how should I proceed with this proof given what I know?


Trying to check if a number is a palindrome through the use of strings

I am trying to check if an input number is a palindrome. I am doing it through strings rather than ints. So, I am taking in a string and reversing it into another string. However, when I use the string compare function it does not give me 0, stating that the strings are not the same. Even when I put in for example "1001", both the input and reverse strings displays 1001. I have figured it out with other methods but am trying to understand what is wrong with this one in specific.      #include <stdio.h> #include <string.h>  int main(void) {     char input[100];     char reverse[100];      int numLen = 0;      printf("Enter a number\n");     fgets(input, 100, stdin);     printf("The number is: %s\n", input);      numLen = strlen(input) - 1;     printf("Length of string is: %d\n", numLen);      for (int i = 0; i < numLen; i++)     {         reverse[i] = input[numLen - 1 - i];          if (i == numLen - 1)         {             reverse[i + 1] = '\0';         }     }      printf("The reverse number is: %s\n", reverse);     printf("The original number is: %s\n", input);      int result = strcmp(input, reverse);     printf("Result of strcmp gives us: %d\n", result);      if (strcmp(input, reverse) == 0)     {         printf("These numbers are palindromes\n");     }     else     {         printf("These numbers are not palindromes\n");     }      return 0; }


Female detective fights corrupt group that kills for a game

A female detective works a case where an all powerful group meets on the "net" to control the world's business (yeah, it's that old, circa mid 90s to mid 00s). She can immerse herself completely in the cyber experience, interacting with characters in a 360 degree landscape, able to talk, walk and travel in the "net". She is seen next to a vehicle and interacting with a video conversation on the street.   She talks to a hacker who eventually helps her. His avatar is a well built, Asian monk with a half robe, and he is gentle and supportive with her in an amused manner. In real life he is a Japanese "Jabba the Hutt" looking bulbous character with cables directly connecting him to the "net". He is on an Asian looking boat docked in a port. He finds the group by accident and then is killed by them, the movie shows the dead body on the boat. The hacker leaves virtual video clips that the heroine can interact with and he helps her find the way to disable the group.  The scenes in the "net" are placid, peaceful and serene where the two travel, but are industrial and stark when the group meets to play the game.   There is a virtual dolphin that the hacker interacts with, swimming on a screen playfully. The dolphin is virtual, not a puppet like in Johnny Mnemonic.

If two finite groups have the same number of elements of the same order, does this necessarily imply they are isomorphic?

I am trying to prove a rather difficult question and I have arrived at a small proof that I can prove true after thoroughly (and exhaustively) analyzing the group structure.   My question is, if two finite groups have the same number of elements of the same order... are they necessarily isomorphic? If not, what are some properties of the group structure that can show that two groups are necessarily isomorphic?


Help on applying a Hadamard gate and CNOT to two single q-bits

I am stuck on a few issues in . (Note: It is at the frame concerning this question.)  In it, from what I understand (which could be wrong) we first apply the Hadamard gate to a qbit in the $\lvert 0 \rangle$ state. Then on that we use a controlled not on the output value, together with another input from another qbit set at $\lvert 0 \rangle$. I don't understand how to work this out and how the $\lvert 00 \rangle + \lvert 10 \rangle$ is derived for the output of combination of the two gates.  Here is what I am thinking (neglecting the $1/\sqrt{2}$ multiplier):  $$ \begin{pmatrix} 1 & 1 \\ 1 & -1 \end{pmatrix} \begin{pmatrix} 1 \\ 0 \end{pmatrix} = \begin{pmatrix} 1 \\ 1 \end{pmatrix} = \begin{pmatrix} 1 \\ 0 \end{pmatrix} + \begin{pmatrix} 0 \\ 1 \end{pmatrix} = \lvert 0 \rangle + \lvert 1 \rangle. $$  There however is another $\lvert 0 \rangle$ coming in from the second (bottom) wire and it interacts with the output from the Hadamard gate. I don't understand how to manipulate the values - have no idea if I can do something such as the following by distribution: $$ (\lvert 0 \rangle + \lvert 1 \rangle) \lvert 0 \rangle = \lvert 0 \rangle \lvert 0 \rangle + \lvert 1 \rangle \lvert 0\rangle. $$  I have no idea why we can do this (if we can even do so), but this is the only way I can see that we could get $\lvert 0 \rangle \lvert 0 \rangle + \lvert 1\rangle \lvert 0 \rangle = \lvert 00 \rangle + \lvert 10 \rangle$, as the author of the video has on the particular time in the video.  Any clarification would be extremely appreciated.


Javascript regex: How do you get the substring match while using match()

From a large minified css file I want to extract the style inside specific media queries. Something like:  .some-class{aaa:bbb;ccc:ddd;}@media (min-width: 500px){.some-other-class{aaa:bbb;ccc:ddd;}}.another-class{aaa:bbb;ccc:ddd;}   The following regex selects the media queries, with a capturing group for the style inside the media query:  regex = new RegExp("@media.\\(min-width:\\d{3,4}px\\){(.+?\\})\\}", "g");   The capturing group result is the part I actually want. But when there are more than one hits how do I access multiple capturing group results. When there is only one the result I am after is the second item in the resulting array, when using str.match(regex);.   Is the only solution using regex.exec(str)[1] in combination with a while loop? Like:  while(result != null){     result = regex.exec(str)[1];     resultArr.push(result); }   I'd much rather use match()...I find that more readable and a more elegant solution, you immediately get an array with you results...although the results I am looking for are only a subset of the results I am getting...   I guess I will have to use the last code snippet I gave, regex.exec(str). Ahh well...

Let $I_c$ denote the functions that vanish at some fixed $c\in\mathbb{R}$. Is $I_c$ a maximal ideal?

Let $A$ be the ring of continuous functions from $\mathbb{R}$ to $\mathbb{R}$ and let $I_c$ denote the functions that vanish at some fixed $c\in\mathbb{R}$. Is $I_c$ a maximal ideal? Give an example of a proper non-zero ideal of $A$ that is not of the form $I_c$ for some $c\in\mathbb{R}$.  My attempt: I think $I_c$ is not maximal, because we can consider the ideal $I_{c,d}$ of functions that vanish at fixed $c,d\in\mathbb{R}$. $I_c$ is clearly contained in $I_{c,d}$, but $I_{c,d}\neq A$ because $f(x)=1$ is not in $I_{c,d}$. Also, I think this ideal $I_{c,d}$ can answer the second part of the question, but it seems like there ought to exist a better example.  Is this right? Or at least a start in the right direction?  Any help appreciated!


EDIT: This question is not a duplicate because I am asking how to show that $1$ is the greatest upper bound of $S$ by using the fact that $\mathbb{N}$ is not bounded above.  Let $S=\{\frac{1}{n}-\frac{1}{m}:n,m\in \mathbb{N}\}$ Show that $\sup S = 1$  To do this we must show that $1$ is an upper bound of $S$ and $1$ is the least upper bound of $S$.  To show it is an upper bound we know $$n>0, n>\frac{1}{n}, and \frac{1}{n}\leq 1$$ $$\Rightarrow 0<\frac{1}{n}\leq1$$ $$\Rightarrow -\frac{1}{m}<\frac{1}{n}-\frac{1}{m}\leq 1-\frac{1}{m}$$  Since $1-\frac{1}{m}<1, m\in\mathbb{N}$ we know $\frac{1}{n}-\frac{1}{m} < 1$ so $1$ is an upper bound of $S$.  Now I'm stuck on showing that $1$ is the least upper bound.  If we let $v\in\mathbb{R}$ be an upper bound of $S$ we want to show $1\leq v$. I am trying to do this by contradiction.  So we assume $v<1 \Leftrightarrow v-1<0\Leftrightarrow 0 <1-v$.  I have been told I can run into a contradiction by recalling that $\mathbb{N}$ is not bounded above, but I'm not sure how to get to the contradiction.


Incline Plane - Coefficient of friction and kinetic friction

A block of mass 90 kg sits on a slope with an angle of inclination 12° above the horizontal. The coefficients of friction between the block and the slope are µk = 0.03 and µs = 0.2.  a.  What is the maximum frictional force that will allow the block to stay in place?  b.  At what angle of inclination will the block start to slide down the slope?  My Question: I am not looking for these two questions to be answered, however, the question has caused me to doubt my understanding of static and kinetic friction re: incline planes.  When i calculated the  the angle at which the block would begin to slide, using the arc tangent of 0.2 i got an angle less than 12 degrees. However, the question is suggesting that the block is at rest with when the incline plane is at 12 degrees. What is my conceptual error in thinking?  My next question:  Wouldnt the minimum angle of the incline plane (tan inverse of 0.2) be needed in answering the first question? that is, having it placed in the formula for the static friction formula = 0.2 x 90kg x 9.81 x cos of (tan inverse of 0.2)? assuming that tan inverse of 0.2 was found already? Is there something wrong with the question or how am i thinking is conceptual flawed?  My Final Question: Is it that the maximum frictional force that allow the block to stay in place is based on whatever angle the incline plane is set at? So, for example, if the incline plane is lowered to an angle of 5 degrees, the max friction force will be adjusted, even though the block would slide at 11.31 degrees? Is it that if lowered to 5 degrees, that the max friction force to overcome would be different?  In other words: If a block is at rest on the incline plane  at an angle of 30 degrees, would the maximum frictional force that would allow the block to stay in place be calculated using 30 degrees, OR would we have to find the minimum angle of the incline plane needed for the block to slide before we can determine the maximum frictional force? That is, find that minimum angle and then substitute it in the formula for  fs(max) = UsMgcos (minimum angle needed for block to slide)?

Let $f$ and $g$ be two holomorphic functions on a complex region. If $\left |  f\right |^2 + \left | g \right |^2$ is constant, then show that both of them are constants. I have tried to use Cauchy Riemann eq. and Laplace eq., however I did not manage to solve the problem.


How to stop file vault decrypting and re enable encryption?

SHORT QUESTION :   Ive got a macbook pro, late 2012, osx 10.10.5, with file vault enabled.   Now when i go to System Preferences > File Vault i get the following decryption screen (see below screenshot). How can i stop it decrypting and re-enable deception ?   LONG QUESTION (with background) :   Ive got a macbook pro, late 2012, osx 10.10.5, with file vault enabled.   When i tried to power it on earlier today it wouldn't start properly the screen was on, but very dull and it couldn't be made brighter using the brighter key. I waited a while but had to press the power button again to shut the machine down, when i powered it back up it took me through the forgot your password wizard.   I hadn't actually forgotten my password, but it wouldn't let me do anything apart from go through the wizard. The forgot password wizard gave me 3 options : 1 + 2 where related to resetting the password and 3 was to do with disabling file vault, so i went with option 3. The computer then booted correctly.   Now when i go to System Preferences > File Vault i get the following decryption screen (see below screenshot). How can i stop it decrypting and re-enable deception ?


Convenient way to check if system is using systemd or sysvinit in BASH?

I am defining common bash files which I want to use across different distributions. I need a way to check if system is using systemd or sysvinit (/etc/init.d/). I need this so I run appropriate command to start the service. What would be safe way to check for this? I currently check for existance of systemctl command, but is that really an option as there might be the case where systemctl command might be available, but it wouldn't necessarily mean that systemd is actually used?  Here is an excerpt from my current bash script:  #!/bin/sh if [ command -v systemctl >/dev/null ] then     systemctl service start else     /etc/init.d/service start fi


Bash script with execute permissions won't run with double click

I have a bash script that has permission to execute, but when I double click it in nautilus it won't execute, instead it opens as text in gedit.   In properties it says open with: gedit, and that doesn't change when I click the reset button.  What do I have to do to make it execute? I'm running Ubuntu 13.04. I never had an issue like this one with 12.04 or with any other distribution in general.  EDIT If I go in terminal and type: ./bashscriptname it runs just fine.


Quantum entanglement and affecting the particles

I am trying to grasp some aspects of the quantum entanglement, but the existing resources (including some of the links here) seem a bit confusing. I am trying to find an answer to the following questions.  If two particles are entangled and then separated, will affecting one of them affect the other (for example, the particle is placed in a field that would set some property of it in a specific direction), or will it disentangle the system? If affecting one particle affects the other, then how is it not possible to use this effect to transfer information (once; for example by affecting the spin of the first particle to be up the other particle would have its spin down)?  Is affecting the particle equivalent to measuring the property affected (for example the spin)?  When a property of the particle is measured, does the particle get entangled with the measuring apparatus? More precisely, does interaction imply entanglement of a sort?  I apologize if the questions are trivial or nonsensical, but I am asking as a layman in the field.


Windows Server 2012 as web server with user authentication - VL/SPLA - is it legal?

I've been wrapping my head around the topic for a few days now and the more I read the less I understand.  Question 1: If I purchase a license for Windows 2012 Server (either Essential/Standard/DataCenter) - am I allowed to use it run publicly accessible web server, with the  assumption that some part of the website requires user authentication (authentication by means of web application itself).  Examples of a software that could run on such web server:   shop, where registered users can purchase items paid forums on-line task management systems that users (customers) purchase subscription access to   It seems to me, that it is not legal (or at least not economical), since according to my understanding of Microsoft's licensing terms:   I need to purchase CALs for each non-anonymous user accessing the s.c. web workloads all users authenticating by any means (not necessarily Windows accounts) are considered non-anonymous thus I would need like thousands of CALs for each potential user of i.e. forum (or purchase External Connector license, but I am not sure whether this is available for Windows Server 2012)   On the other hand, the discontinued Windows Web Edition (which license include s.c. "CAL waiver") made no restrictions on whether the web-workload users where non-authenticated or authenticated ones. So maybe my understanding is wrong, and CALs/EC are not required for authenticated users accessing web-workloads only?  Reference information:          Question 2: If not - is SPLA a solution in this scenario?  If I license Windows Server through SPLA - is scenario described above legal?  Question 3: Is Essentials edition less restrictive since it does not require CALs?  Windows 2012 Server Essentials does not require CALs, but is limited to 25 users. Is this legal or technical limit? Would Essentials edition be valid in scenario described above?


One who expresses (or the act of) feigned sympathy/interest in hopes of being recognized for it

I'm trying to find a word that encompasses both these ideas. I thought pharisaic would be a bark up the right tree, but it appears to pertain more to hypocrisy and legalism.  Ideally the word should encapsulate the idea that some form of good is being displayed for the primary purpose of self-gain.  I understand that such an action could be hypocritical, but that word does not necessarily imply the act of doing good only for the praise it brings.  The Pharisees are a great example of this (with their ostentatious tithing), but the word named after them doesn't seem to have been applied to that aspect of their character.


I am trying to work with a shapefile using shapely, fiona and python. The original coordinate system is in latitude and longitude that I am trying to convert to state plane system. So I want an updated shapefile with coordinates as statePlane. I converted the json object:  fc = fiona.open("sample.shp")    geoJsonObj = shapefile_record['geometry'] array_coordinates = np.array(geoJsonObj['coordinates']) array_newCoordinates = copy.deepcopy(array_coordinates) for counter in range(0,len(array_coordinates[0])):     long,lat = p1(array_coordinates[0][counter][0],array_coordinates[0][counter][1])     #where p1 is a function to do the conversion     array_newCoordinates[0][counter][0] = long     array_newCoordinates[0][counter][1] = lat  geoJsonObj['coordinates'] = array_newCoordinates.tolist()   when i check the coordinates, i get state plane coordinates according to the transformation.  n. However, when i open the individual shapes/polygons within the shapefile, the coordinates are still latitude and longitude. why does this happen?  ----EDIT 1-----  from pyproj import Proj, transform import fiona from fiona.crs import from_epsg  dest_crs = from_epsg(4269) shape = fiona.open("Sample.shp") original = Proj(shape.crs) # EPSG:4326 in your case destination = Proj('+proj=lcc +lat_1=36.41666666666666 +lat_2=35.25      +lat_0=34.33333333333334 +lon_0=-86 +x_0=600000 +y_0=0 +ellps=GRS80 +datum=NAD83  +no_defs') with fiona.open('new.shp', 'w', 'ESRI Shapefile',shape.schema.copy(),crs = dest_crs) as output:     for feat in shape:                print feat['geometry']['coordinates']         for counter in range(0,len(feat['geometry']['coordinates'][0])):             long,lat =  feat['geometry']['coordinates'][0][counter]             x,y = transform(original, destination,long,lat)             feat['geometry']['coordinates'][0][counter] = (x,y)         output.write(feat)

TV mini-series about a boy transported to another world

I don't have much to go on but...  I watched this some time between 1998 - 2003. It was a TV miniseries (maybe 8-12 eps I think), about a boy (age 11/12 I think) that gets transported to a magical world.  At some point he pairs up with an older (or possibly just taller) girl, who is from that world.  At some point they go to a castle that has big colourful creatures of some kind. In one of the later episodes they go across a wooden bridge over a chasm.  I watched it in the UK, I can't recall if it was UK, Australian or USA but definitely in English.   Unfortunately that's all I can remember!


Further Clarification Needed: Martingale to prove f(x+s) = f(x)

Given $f$ is a bounded continuous function on $\mathbf{R}$ and $\mu$ is a probability measure such that for all $x \in \mathbf{R}$ $$ f(x) = \int_\mathbf{R}f(x+y)\mu(dy) $$  Please help to show that $f(x+s) = f(x)$ for all $s$ in the support of $\mu$. (The support of $\mu$ is the smallest set $E$ s.t. $\mu(E)=1$.) The hint is that we can try to use martingales to show $E[f(x+X_0)-f(x)]^2=0$, where $X_0$ has distribution $\mu$.  So far I've constructed a martingale $M_n=f(x+S_n)$. Here $S_n = \sum_{j=1}^nX_j$ and $\{ X_j\}$ are i.i.d. with distribution $\mu$. But I've no idea on how to connect this martingale with the previous hint.  I came cross another post about the same question on the forum, but it ends with the martingale that I stated here. So I'm wondering if anyone can provide some further insights about how to finish the proof. Since this is a hw problem, I've been working on it for three days only to get to this point. I sincerely appreciate any inputs that people will give.  Thanks a ton!

Can a shapechanger be affected by Polymorph if they are forced to be willing?

, could a werewolf or other shapechanger be subject to Polymorph?  What I'm reading of Polymorph, RAW PHB p.266,  is:   "an unwilling creature must make a Wisdom saving throw to avoid the effect", and "a shapechanger automatically succeeds on this saving throw"   Interestingly, the wording for True Polymorph, PHB p.283, is different, being simply: "Shapechangers aren't affected by this spell." So, naturally, I simply seek clarification on whether I am interpreting this correctly:  Could a werewolf or other shapechanger be subject to Polymorph assuming it were charmed into being willing via Suggestion or similar?  ( covers True Polymorph, though non-true Polymorph has different wording.)


Motivation for/history of Jacobi's triple product identity

I'm taking a short number theory course this summer. The first topic we covered was . I still have no sense of why this is important, how it arises, how it might have been discovered, etc. The proof we studied is a bit on the clever side for my taste, giving me no sense of how said proof might have been discovered. Can anyone help?

Is there any point to booster car seats with anchors?

Our child is ready to switch from a five-point harness child car seat to a car booster seat, and we looked at a couple of models in a store. We saw one model that has clips on it to clip into the anchors that the five-point harness uses.  Is there any point to this? The difference is that a five-point harness replaces the regular seat belts and must be strongly connected to the car's frame. A booster seat just holds the seat belt in a safe position on the child's body. I don't think there's any tension between the car and the booster seat in a crash, so why would it need to be anchored?  Has anyone seen any reliable information on this feature?
