Sqlserver 2019 Partitioning based on Data Classification?

Now that sqlserver 2019 has been around for a while, this is a re-ask of a prior question that was not really answered in the way I had hoped:  Is it possible to partition a database based on the Sqlserver 2019 data classification feature?    Explanation/Detail: I would like to column partition the entire database schema so that our "high sensitivity" data is processed and stored separately, perhaps in another instance in a different location.  This to improve security of our data, understanding that there would be a performance cost.  I would like to maintain the current schema for application compatibility purposes, just store the data differently for security reasons.


IEEEtran document class — how to align five authors properly

How do I align author names such that the first three authors appear in 3 column format and the last two in two column?  \author{\IEEEauthorblockN{1\textsuperscript{st} Given Name Surname} \IEEEauthorblockA{\textit{dept. name of organization (of Aff.)} \\ \textit{name of organization (of Aff.)}\\ City, Country \\ email address} \and \IEEEauthorblockN{2\textsuperscript{nd} Given Name Surname} \IEEEauthorblockA{\textit{dept. name of organization (of Aff.)} \\ \textit{name of organization (of Aff.)}\\ City, Country \\ email address} \and \IEEEauthorblockN{3\textsuperscript{rd} Given Name Surname} \IEEEauthorblockA{\textit{dept. name of organization (of Aff.)} \\ \textit{name of organization (of Aff.)}\\ City, Country \\ email address} \and \IEEEauthorblockN{4\textsuperscript{th} Given Name Surname} \IEEEauthorblockA{\textit{dept. name of organization (of Aff.)} \\ \textit{name of organization (of Aff.)}\\ City, Country \\ email address} \and \IEEEauthorblockN{5\textsuperscript{th} Given Name Surname} \IEEEauthorblockA{\textit{dept. name of organization (of Aff.)} \\ \textit{name of organization (of Aff.)}\\ City, Country \\ email address} }

Problem viewing document in TEXmaker "Fontspec requires XeTeX or LuaTeX"

I'm trying to use a template from online and when I upload the zip into Texmaker it gives the following error   "! Fatal fontspec error: "cannot-use-pdftex" ! ! The fontspec package requires either XeTeX or LuaTeX to function. ! ! You must change your typesetting engine to, e.g., "xelatex" or "lualatex" ! instead of plain "latex" or "pdflatex". ! ! See the fontspec documentation for further information. ! ! For immediate help type H ."  What I have tried  I've looked at several posts in this forum, but none seem to have worked. I tried making a custom command for both XeLatex and LuaLaTeX, but neither has worked. I think maybe I don't have something properly downloaded? My custom commands look like this   XeLaTeX: xelatex --interaction=nonstopmode %.tex  LuaLaTeX: lualatex --interaction=nonstopmode %  Possibly these are wrong though. When I run either command, it just says  "Error : could not start command"  Thanks for the help, and once again I've read most of the threads related to this, but to no avail, so I think I'm doing something else wrong.   Below is what my texmaker preferences look like...let me know how to change them in order for this to work. Running quick build or my custom command doesn't work and results in the same error

When I edit a web page in safari. with opened visual studio code a moment ago, and didn't close it.  The cpu just jump higher, so I close that web page and visual studio code, then the cpu jump down to normal.  Not sure what case this.  I have notice that the mds is lower when the mds_stores are high.  PS: it's macOS 10.15.1  Edit:  I didn't think it's duplicate of another question , because in that question, the situation is    lower cpu consumer: mds:11.9%, mds_stores:9.6,  compare to mine:    mds:1.3, mds_stores:701.8(kind of killing my cpu) the cpu drop down to normal after I close the webpage & vscode.

options override for openssh client configuration

Since I want to protect my ssh connections, I set some global cipher suite options to restrict set of used algorithms. But recently I've encountered a server which doesn't support some of those algorithms. So, I need to selectively enable deprecated algorithms for a specific host record in client (my system) configuration.  I found out that the options override is not working as I expected. Let's take a minimal (not-)working example for the github:  HostKeyAlgorithms ssh-ed25519-cert-v01@openssh.com,ssh-ed25519,ecdsa-sha2-nistp521-cert-v01@openssh.com,ecdsa-sha2-nistp521,ecdsa-sha2-nistp256  Host github     HostKeyAlgorithms ssh-rsa     Hostname        github.com     Port            22     User            git     PubkeyAuthentication yes     IdentityFile    ~/.ssh/some-filename-here   Having that, I receive the following error (HostKeyAlgorithms is not overriden at all):  debug1: /home/username/.ssh/config line 14: Applying options for github <...> debug2: kex_parse_kexinit: ssh-ed25519-cert-v01@openssh.com,ssh-ed25519,ecdsa-sha2-nistp521-cert-v01@openssh.com,ecdsa-sha2-nistp521,ecdsa-sha2-nistp256 <...> Unable to negotiate with 192.30.252.130: no matching host key type found. Their offer: ssh-dss,ssh-rsa   It is similarly not working for the global PubkeyAuthentication no options with an override in a host configuration.  Also, the match doesn't help either:  match host github     HostKeyAlgorithms ssh-rsa   So, is there a way to selectively redefine those options?  NOTE: I'm using the openssh-7.1_p2-r1 on gentoo.


Prove convergence of $ \sum_{n=1}^{\infty} a^{\ln n}$ for $0<a<\frac{1}{e}$

Prove the convergence of the series:   $$\sum_{n=1}^{\infty} a^{\ln n},\,\text{for} \,\,0<a<\frac{1}{e}.$$   Attempt. I have proved the non-convergence in the case $a\geq 1/e$ (using the comparison test and getting $a^{\ln n}\geq \frac{1}{n}$). In case  $0<a<\frac{1}{e}$, I get $a^{\ln n}<\frac{1}{n}$ and the above test doesn't work. Ratio test, root test are also not applicable here.  Thanks in advance for the help.

No non-trivial clopen sets in $\mathbb{R}$? How to give a direct proof?

How to give a direct proof of the following result?     Let $A$ be a subset of $\mathbb{R}$ such that $A$ is both open and closed. Then $A$ is either empty or all of $\mathbb{R}$?   My work:   If $A$ is not empty, let $u \in A$. Then there is some open interval $(a,b)$ such that $$u \in (a,b) \subset A.$$  Now if $\mathbb{R} - A$ is not empty either, then let $v \in \mathbb{R} - A$. Then there is some open interval $(c,d)$ such that  $$v \in (c,d) \subset \mathbb{R} - A.$$  Suppose that $u < v$.   Since $$\emptyset \subset (a,b) \cap (c,d) \subset A \cap (\mathbb{R} - A) = \emptyset,$$ we must have $$(a,b) \cap (c,d) = \emptyset.$$ So we can conlclude that $$b \leq c.$$ But $b \in A$ and $c \in \mathbb{R} - A$. So we must have $$b < c.$$  What next? Can anybody here please help complete the proof from here on?  An edit based on a comment by Marc Paul:   Let us assume that the set $A$ is a non-trivial clopen set in $\mathbb{R}$. Let us define a function $f \colon \mathbb{R} \to \mathbb{R}$ as follows:  $$f(x) \colon= \begin{cases} 1 \ \mbox{ for } \ x \in A; \\ 0 \ \mbox{ for } \ x \in \mathbb{R} - A. \end{cases}$$   Let $V$ be an open set in the range space $\mathbb{R}$. We show that the inverse image set $f^{-1}(V)$ is open in the domain space $\mathbb{R}$.   The following cases arise:   If $0, 1 \in V$, then $f^{-1}(V) = \mathbb{R}$.   If $0 \in V$ but $1 \not\in V$, then $f^{-1}(V) = \mathbb{R} - A$.   If $1 \in V$ but $0 \not\in V$, then $f^{-1}(V) = A$.   And, if $0 \not\in V$ and $1 \not\in V$, then $f^{-1}(V) = \emptyset$.   Thus, $f^{-1}(V)$ is open in the domain space $\mathbb{R}$.   Hence the function $f$ is continuous.   What next? How does this lead to our desired conclusion?   [Yet another edit, again based on valuable comments from Marc Paul: ]  So if both $A$ and $\mathbb{R} - A$ were non-empty, then let's suppose $a \in A$ and $b \in \mathbb{R} - A$, and we can assume without any loss of generality that $a < b$.   Then $f(a) = 1$ and $f(b) = 0$. So by the intermediate value theorem there is a real number $c \in (a,b)$ such that $f(c) = 1/2$, which is a contradiction because the image set of $f$ does not contain $1/2$.


Evaluating a definite integral involving $\log(1+x)$

Find  $$\int_0^1\frac{x\ln(1+x)}{1+x^2}dx$$ I think it has not an anti-derivative  because i tried it with different ways such as using the sub $$x=\tan{y}$$ to be  $$\int\tan{y} \ln\left(1+\tan{y}\right)dx$$ so what is the procedure to solve it?


There is a length limit to Windows file extensions?

If I want to create a new file extension for a binary/text data file that will open on my own application (extension ".mylongfileextensionname" for example), will Windows list it with my aplication (considering that I already listed it on Windows Registry before)?  There is a length limit, I mean, on my example should I use ".mylong" or any specific layout?

VLC crash on Ubuntu 17.10 Screen Freezes

2days ago I upgraded my Ubuntu from 17.04 to 17.10, all the process went fine and the upgrade was successful. But after some few hours I played a .mp4 video with vlc players the video plays on full screen for 3 to 4 seconds and freeze the screen, audio keep playing but the video stopped and the keyboard and mouse stops responding, the only way to get out of this is to force shutdown the computer and restart it. Happens every times with Ubuntu 17.10 never experience the problem with 17.04. How to get out of this am a vlc fan.

Sci fi book, Jesus returns in the 1950's and the 1980's

I'm saying this was sci fi because scientists in the 1980's managed to send a document to their 1950's counterparts.  Jesus had appeared in the 1950's and it was covered up by USA government, he then said he'd return in the 1980's. A special task group was formed. I remember 'Operation Easter Bunny' and they decide to keep it quiet then as well.  In the eighties an operative is showing him around New York while the surveillance team monitor everything, for some reason (I can't remember why) he takes him to the cinema to watch Deep Throat, the agent then gets very ashamed while they're viewing it and regrets his impulse, graphic description of Linda Lovelace doing her stuff. He then takes him to see Clint Eastwood in a Dirty Harry film.  Back in the fifties / early sixties they are astounded that a 'stag movie' of such hardcore content is publicly shown. They also wonder who Clint Eastwood is until some professor's daughter identifies him as the young actor from Rawhide who plays Rowdy Yates.  The book (IIRC) jumped back and forth over the 30 plus years and I got a bit confused ....some of the science people were young and old versions of the same people. I can't remember what happens but the Linda Lovelace  and Clint Eastwood bits should help


Proving two lines in vector form intersect algebraically

let $x,y,a,b,c,d$ be vectors and $r,k \in \Bbb{R}$ with vector $d$ not being a scalar multiple of vector $b$ How would you prove that the line $\vec{x}=\vec{a}+r\vec{b}$ intersects the line $\vec{y}=\vec{c}+k\vec{d}$ algebraically in $\Bbb{R^2}$?  Geometrically In $\Bbb{R^2}$ since $\vec{b}$ and $\vec{d}$ are not scalar multiples then they are not parallel and since they are in the x-y plane then obviously the two lines will not intersect, however i am having trouble expressing this algebraically


What program specifically sets /var/log/boot.log to 644 perms in RHEL/Centos 6?

I've been assigned to lock down all /var/log files so that they cannot be read except by the root user.  I've been stumped by the /var/log/boot.log file.  It seems that after every boot the file no matter what what previous permission state gets set to 644 permissions.   I've gone through the exercise of changing the umask in a number of key /etc/init.d files and functions to no avail.  Anybody got any idea as to the specific program doing this and maybe how to get the perms on /var/log/boot.log to be 600?


Can you use Magic to Defend? Fate Core rules in a Dresden Files universe

The annotation on YS253 says that you can't use a Block or Counterspell as a defense action.  But as in Fate Core's , it makes sense that it's always possible to use magic to , rolling Discipline just like any other skill.  In that case, I'm considering the Practitioner will use a simple Evocation (and so, incur mental stress) to define an armor rating instead of weapon rating like how it works for attacks:   if he surpasses the attack roll, he succeeds in deflecting the attack. if he doesn't surpass the attack but still succeeds in the Discipline roll for controlling the spell, he gets hit but still has the armor rating to reduce the stress inflicted by the attack if he fails on the Discipline (control) roll he must deal with backslash or fallout prior to resolving the action.   The caveats on this are:   Rules become too complicated (by adding armor ratings to defense rolls). This would make attack spells less effective (or less dangerous), probably causing a lot of ties during conflicts. A successful defense roll makes the armor rating useless, so it would be just simpler to buy a use Discipline to defend against Magic Stunt or even allow all Practitioners to do that for free.   So, what would be the best option to defend with magic in DFRPG?


Dimmer switch with ceiling fan instead of remote

Is there any reason to use a remote control with a ceiling fan (that most come with), which requires a battery and can get lost, when a simple dimmer switch can be installed to regulate the speed? Is it, for some reason, bad to use a dimmer switch with a ceiling fan? This assumes the fan does have a separate wall switch and is not directly wired with a chain switch, like some old ones used to.

How to install jdk 8 and NetBeans8 ubuntu 14.04 lts

I have a 951G-2HnD as a router. All connections are via ethernet cables. I observe the following:   When I connect to the ISP via router, speed is about 270 Mbit/s, while ISP claims my plan has 500 Mbit/s speed limit. When I connect cable from ISP directly to ethernet port on my PC, I indeed get about 500 Mbit/s download speed. When I download files from another PC connected to the same router, the speed is about 900 Mbit/s which is correct for gigabit LAN.   Now because of 3, I think that the problem is not in router processing power. I suppose something is wrong with NAT processing. How do I improve speed so NAT connection is as fast as direct one? Or at least how do I debug the problem?  Just in case, I disabled all NAT rules except the main one:  /ip firewall nat chain=srcnat action=masquerade out-interface=ether1-gateway   This did not improve the speed.

How do I center my css menu dead center (fluid style)

I really need your help,  How would I be able to dead center (vertically and horizontally) position my css menu smack dab in the middle of the users screen. (We are assuming that different people use various screen resolutions) therefore, I would be looking for a fluid example to work from.  Here's the CSS and HTML markup in question:    <!DOCTYPE html>

How to I copy bootable USB flash drive to larger drive?

I've tired a number of things to get this to work and I'm missing something.   I ran out of space on my 8gb bootable flash drive. I'm running 12.04 server. The drive has sda1 (primary 4gb), sda2 (extended 4GB) and sda5 (swap 4gb).  I tried copying old drive to new drive using ddrescue (whole drive copy) and then resizing on another linux box using gparted.  I made sda1 ~22Gb (75% of the drive) and used the remaining space for sda2 and sda5.  When I tried booting it I get to the GRUB menu and when I select the OS I get a message about not enough room or space.    Next try.    I dd'd the MBR of the new drive and then created sda1 - primary linux 83 (75% of sectors on drive), sda2 - extended 5 (25% - remaining sectors), sd5 - logical linux 82 swap (same sectors as sda2).  I then wrote the changes and exited fdisk.  I then ran ddrescue with the following command:  ddrescue -d -f -r3 /dev/sda1 /dev/sdb1  (old drive copied to new drive).  It competed successfully.  I mounted the new copied partition and ran df to see the free space and it shows the same amount as the old small drive -97% used.  I thought I had to resize or something so I moved drive to other linux box and ran gparted.  Didn't find that the partiion needed resizing.    The new partition has the same UUID as the original but I think i might need to copy the old swap partition UUID to the new one and I don't know how - only how to randmly generate a new one.   So, where did I go wrong here. Am I close to getting this right?


after the  a few hours back I managed to get a working desktop after using an ethernet cable and sudo apt-get install ubuntu-desktop  But now when I try to run ubuntu software center from CLI this is what I get   rick@Abigail:~$ sudo software-center  Traceback (most recent call last):   File "/usr/bin/software-center", line 34, in <module>     import gtk ImportError: No module named gtk   Any guesses how to fix this.

If $n$ is odd, then there are exactly two conjugacy classes of n-cycles in $A_n$ each of which contains $(n - 1)!/2$ elements.

My approach:  Define $X = \{\alpha \in A_n \ | \ \alpha \  \textrm{is an n-cycle}\}$ and the group action $G: A_n \to S_X: g \mapsto gxg^{-1}$. Then for an $\alpha$ the stabilizer group is $\{\beta \ | \ \beta \textrm{ is an n cycle or the identity} \}$ (I'm stuck on proving this is the entire stabiliser group), and the orbit of $\alpha$ is the conjugacy class of $\alpha$ itself, so by the orbit-stabilzer theorem the size of the conjugacy class is equal to the size of the quotient group of $G$ and the stabiliser which would be $n!/2/n = (n - 1)!/2$.   Because there are $(n - 1)!$ $n$-cycles there must be exactly 2 conjugacy classes. So now the only part left is proving that their size must be $(n - 1)!/2$ which is also why this differs from the question linked as duplicate.  Thanks for any help.


Create keyboard shortcut for an operator using python?

Aborted package installation, now synaptic and apt won't complete

Fresh install of lubuntu xenial  Was having issues where print service wasn't found ().  Cups wasn't installed for some reason (maybe another streamlining choice lubuntu made?).  Tried to install cups sudo apt-get install cups --install-suggests  It was doing stuff for hours and slowing down the system.  Trying to look up why it was taking so long (probably suggests was a bad choice?), I closed the terminal window by accident aborting the process.  Now runit and git-daemon-run are causing issues.  I can't complete anything in synaptic or apt without it being angry that they are broken.  I've tried quite a few things, but here's probably the most relevant thing to paste:  $ sudo dpkg --configure -a Setting up runit (2.1.2-3ubuntu1) ... start: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused dpkg: error processing package runit (--configure):  subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of git-daemon-run:  git-daemon-run depends on runit; however:   Package runit is not configured yet.  dpkg: error processing package git-daemon-run (--configure):  dependency problems - leaving unconfigured Errors were encountered while processing:  runit  git-daemon-run   Please help!  EDIT: @jokerdino was correct in marking this as a duplicate.  Trying the advice of @minigeek gave the Upstart error mentioned in the dupe link.  Removing runit seems to have worked fine:  sudo dpkg -r --force-all runit sudo apt-get remove --purge git-daemon-run


Prevent users from starting multiple accounts?

I know that in the end it, can't be done.  But, what are the options to:      a) limit the options for persons to create multiple accounts,   b) increase the chance of detecting multiple accounts / person    for a blog-like web service? (people can sign up for their own blog)  Update: I think the 'limit the options' has been answered nicely. (there is no reliable method, but we can raise the bar) However, I would still like to know what other options there are to detect multiple accounts?

undefined reference to ... in a nested class trying to declare an array?

I'm trying to initialize an array called ARRAY inside the constructor of a class called CLASS_A and this array is supposed to be accessible by the nested class CLASS_B. I thought of making the array a template but that was when things started to get a little fuzzy with how to go about the syntax.   I'm almost certain that declaring the ARRAY static is part of the solution and maybe making the type const int a template like A so then the template would look like template <class A, const int D> and the declaration A ARRAY[SIZE];. Anyways I initially got this error compiling the code below and then I made some changes and got a different error.  This is a linker error by the way  nested_class_incomplete_type.cpp|16|undefined reference to `CLASS_A<3>::ARRAY'| nested_class_incomplete_type.cpp|28|undefined reference to `CLASS_A<3>::ARRAY'|   edit duplicate code.


Am I being scammed? (UK visit visa refusal)

I am from Pakistan. I applied for a 4 week UK family visit visa with my 6 year old daughter and they refused, my refusal issue is the same. I am going to quote my refusal letter:  [  These objections and reasons are not as like they thinking I have my bank statement and transactions including Rs. 4 lac balance I have transactions of my salary in statement and my husband recently employed he is also have his salary transaction in the same statement because we are both using our joint account.  I just want to go to the UK and meet my family for 4 weeks and I am with my 6 year old daughter. My husband is not going with us due to his job.  Now please guide me; should I go for an Administration review and provide them my bank statement because my visa was rejected on 26 July 2016 I still have time period for administration review OR should I reapply immediately to remove all these objections and give them more evidences I mean bank statements and our pay slips etc? Kindly guide me what to do which way will work. Your quick help and guidelines will help me.


Adding elements to a HashSet while Iterating

So my program is a version of paint.   It creates a canvas and allows me to paint over the canvas with my mouse by getting Point's from the mouse using a HashSet and Iterator.  It also connects to another identical program via a DatagramSocket and sends the Point's it generates to the other program which displays this on it's canvas.  To do this I use a Runnable thread that listens for incoming Point's and adds them to the HashSet.  My problem is that i get java.util.ConcurrentModificationException because I add Point's to the HashSet from the connected program via the thread while painting.   I don't see how to get around this exception since I want the canvas to update live.     solved this using a CopyOnWriteArraySet with which I could simply replace my HashSet :) thx for all your support!


Which library do I have to download in order to get itoa() in C

I want to use itoa() in C . Which library do I have to download?  I would prefer to include a specific library instead of using my own code, but that may be wrong.  I have seen several examples of how to use itoa() but my problem is how to get the library file.


How can I fill the area between two concentric circles (or even slightly eccentric) using only tikz (preferably without pgfplots)? I have found many sort-of similar questions, but nothing that quite addresses this.  \documentclass[tikz,border=1pt]{standalone}  \begin{document} \begin{tikzpicture}     \draw (0, 0) circle (1);     \draw (0, 0) circle (1.2); \end{tikzpicture} \end{document}   I want to fill the area between these two with the color gray. I would prefer not to fill the inner circle with white color, but leave that transparent, or unfilled.


Why are cash advance limits lower than my credit limit?

QGIS locked into fullscreen mode on Ubuntu 12.04

No crash in this case, but I made the mistake of toggling to fullscreen mode on my netbook running Ubuntu 12.04. It's now impossible to escape , and it seems to have disabled the popout unity launcher as well. Steps I've already taken:   Alt-Tab to move to a different program, then back - QGIS remains in fullscreen Alt-V, Ctrl-F and F11 get no response I've unistalled QGIS, deleted the /.qgis/ profile data folder, and reinstalled. Still launches fullscreen   To add to the weirdness, it now launches - still in fullscreen - into a different workspace than the active one.  I realize this has the sound of a Unity problem, but it's just this program that has a malfunctioning UI.  Thanks to all the crew; this in no way changes my opinion of QGIS as an essential tool.


Best Graph for Comparing Data with a Nominal DV and Nominal IV?

I am currently working on a research proposal in which I am testing a new concussion recovery method's effects on personality change from concussions. So right now, my IV is either New Recovery or Traditional Recovery which is nominal. My DV is whether or not personality changed, so I feel this would be nominal since it seems to be mutually exclusive. With that being said, unless I am incorrect with labeling the DV as nominal, how would I plot this data? I am having difficulty determining how to best represent this data.  Thank you


Can hidden lines in heading tags and content sections help SEO?

Will the hidden lines in this H1 tag and content section help SEO? For example:
Red Carpet  Made to measure floor carpet in England with Premium quality
  Here I only want to show "Red Carpet" and I don't want to show the rest. So if I make other line hidden, will Google still read that lines and give more strength to my page?  Is there any benefit that I will get adding hidden content?

Trilogy about a planet ruled by women called “Bahronas”, another planet where catlike creatures listened to singing scarves

I read this set of stories in the 80's.  What I recall is this:  A planet where the ruling caste was made up of humanoid women.  These women would, as almost pubescent girls, go out into the wilderness with only a spear and attempt to kill an animal in a life or death struggle.  When it happened, they would burst open a DNA packet in themselves that caused them to rapidly mature, their skin to become bronze colored, and give them some kinds of other "powers", I think over fire.  They were called "Bahronas", I think.  The population of this planet was primitive, but they were in contact with an advanced humanoid species, I think of actual homo-sapiens, who were there observing and advising them.  The advanced species wasn't allowed to intervene, just advise and watch.  The main character was a castaway boy, crash landed on their planet and stranded.  He became friendly with the ruling family of Bahronas and entered their confidence.  We find out through the course of the story that he's been genetically engineered and is not a normal boy.  At some point, the advanced species notices him and explains that he is a clone of a famous explorer and a spy, and they explain that they won't do anything in front of him.  The central part of the story is something of a blur, but, the final part of the story is told in a dramatically different style and shifts to a planet populated by catlike creatures who live in boughs of silk scarves, some of which sing.  THey are recording devices which play back the songs.  On this planet, there is another silk scarf, a white one, which doesn't play a song at all.  The cat creatures are greatly disturbed by it when they hear it's message, which they don't understand.  The narrator then goes on to say that it's a spoken word recording, made by the explorer which the boy was a clone of, explaining that he is captured and held hostage on the planet which makes the scarves, and forced to help make them (I think.)


Convert binarystring to int, in C or C++

I have got a String filled up with 0 and 1 and would like to get an Integer out of it: (platform in an Arduino UNO)  String bitString = "";  int Number; int tmp;  bitString = "";   for (i=1;i<=10;i++)   {     tmp= analogRead (A0);     bitString +=  tmp % 2;     delay(50);   } // now bitString contains for example "10100110"  // Number = bitstring to int <------------- // In the end I want that the variable Number contains the integer 166


How do i remove appended data, with a trigger that is appended with ajax?

I made a function using jQuery and Ajax to append info from a separate PHP file to another file. Lets call the destination file "Homepage" and the file containing the data "Template".  So i use this function:  var box = $('#infoPageContainer'),     close = $('.arrow');  btn1.click( function(){     event.preventDefault();     if( box.hasClass( 'active' )){         box.removeClass( 'active' );         box.css( "width", "0%" );          $('#placeholder1').fadeOut(600);          setTimeout(function(){             $('#placeholder1').html("");         },1000);      } else {          box.addClass('active');         box.css( "width", "100%" );          $.ajax({             url: 'template/parts/Template.php',             success: function(data){                 $('#placeholder1').html(data).fadeIn(600);             },              beforeSend: function(){                 $('#placeholder1').html("loading").fadeIn(600);             }         });     } });   To append this data:

Veldopstellingen

Dit is de titel

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.

     As you can see I use a switch that checks for an 'Active' class and runs the respective function. What I want however, is the function removing the appended data to be triggered by a button that is appended (Img with Arrow class). So like this:  close.click( function(){     event.preventDefault();     box.removeClass( 'active' );     box.css( "width", "0%" );      $('#placeholder1').fadeOut(600);      setTimeout(function(){         $('#placeholder1').html("");     },1000); });   But when I do so, nothing happens even tho the function does work when I don't use an appended object as trigger. What should I do?


I've been taking a look at some proposed proofs for the following theorem:  If $f$ is Riemann integrable in $[a,b]$ and is bounded from zero ($\inf\{|f(x)|,x\in[a,b]\} > 0$), then $\frac{1}{f}$ is also Riemann integrable there.  For convenience, let's denote $g(x)=\frac{1}{f(x)}$, and also for some partition $P=\{a<x_1<x_2<\dots<x_{n-1}<b\}$: $M_i=\sup\{f(x)|x\in[x_{i-1},x_i]\}$ and $m_i=\inf\{f(x)|x\in[x_{i-1},x_i]\}$, and $G_i$ and $g_i$ are the same except for $\frac{1}{f}$. The ways I've been coming up with to deal with the fact that $f$ could have discontinuities & hop between positive and negative values were becoming increasingly ugly and I came here to see smarter alternatives, but about 3 different answers I saw were sort of ignoring that problem altogether in a way that doesn't seem right to me. The problem I had is this: I want to say that $M_i=\frac{1}{g_i}$ and $m_i=\frac{1}{G_i}$ or, really, anything in a similar vein, but it just doesn't seem true: if $f$ does hop between positive & negative value in a given interval created by $P$ then the infimum of $g$ in that interval will be the reciprocal of the supremum of the negative values of $f$ in that interval, unless I'm missing something, and that isn't guaranteed to be (or rather: isn't going to be, I think, in most cases in which $f$ does behave as described) $M_i$ or $m_i$. A similar deal going on with the supremum, of course. To quote one of the aforementioned answers I mentioned which seem to ignore this:  Quote:  It should be easy to see that Gi,gi are 1/Mi,1/mi but not necessarily in that order.  Here's a counter-example (unless I'm doing something really silly here, which certainly is a possibility): $f(x)=\begin{cases} x &\text{} x\in [1,2]\\-x &\text{} x\in(2,3]\end{cases}$ $\Rightarrow g(x)=\frac{1}{f(x)}=\begin{cases} \frac{1}{x} &\text{} x\in [1,2]\\\frac{-1}{x} &\text{} x\in(2,3]\end{cases}$ Clearly, $f$ is Riemann integrable in $[1,3]$, and it is also bounded from zero in this interval, so the conditions are fulfilled. With respect to the partition $P=\{1<3\}$, for example, we have $M_1=2$, $m_1=-3$, but $G_1=1$, $g_1=-\frac{1}{2}$. $G_1$ for example isn't the reciprocal of either of the two. So my main question here is: am I missing something? Are any of the things I described above off, somehow? And in addition: how would you handle this proof? Things I had considered are:  Define a refinement of $P$ which includes all discontinuity points of $f$ to prevent this kind of "hopping" behaviour I mentioned, but there's nothing to promise me the amount of discontinuities is finite, and the definition of a partition I've been working with requires a finite amount of points. Figure out some slightly more complex expression to describe the actual supremum/infimum ($G_i$/$g_i$) we're going to end up with, but then the transition from $G_i-g_i$ to $\frac{f(x)-f(y)}{c^2}$ for some nonzero $c$ becomes significantly less nice. I might be able to still move forward with this somehow but it feels messy.  There were several other methods I had considered, some of which might have even worked, but they all seemed incredibly tedious and messy and I feel like I've been overcomplicating this. I'd really appreciate some help with clearing up this mess going on in my mind right now. EDIT: I'm not familiar with the concept of a set's Lebesgue measure, so I'd prefer a solution that doesn't make use of it, if possible.

How do I create a freeze-frame effect with video editing?

I am using Blender 2.76b.  None of these suggestions have worked for me:   Doing a hard cut. I am doing this multiple times to leave a gap, which I want to fill in with the freeze frame RMB to grab the right arrow, which I want to extend Press g and drag it, which will create a freeze frame on the last frame if extended beyond the original size.   I've tried this selection and tried both g and e and neither work. It seems to want to let me either move it or make the clip smaller but not extend beyond its original size.  Any ideas?


Why and how is sound produced when two objects hit each other?

When two objects collide and undergo a partially inelastic collision (so every one we experience in every-day life), they rebound to a certain degree, but kinetic energy is not conserved. Thus, the energy of motion must be converted to another type of energy. Thus, when two object collide, the most common forms of energy that kinetic energy is converted to are sound energy and thermal energy.   Some collisions are louder than others just because they cause a bigger local variation of pressure (which then propagates through air until finally gets heard). So, why some objects, even if the velocity before and after the collision seems to be the same, are louder than others? I mean, how do the different material properties enter in the phenomenon?  How and why, by means of solid and fluid mechanics or with an heuristical microscopical reasoning, can this process be explained?


In my textbook, i came across the proof for when $x^2$ $\equiv$ -1 (mod p) has a solution, when p is of form 4k+1. This was pretty easy to prove, but then the next part of the proof was to prove that for each prime of 4k+1 there exists a solution. They had written taking x = ($\frac {p-1}{2}$)! , we get desired result. But i couldn't understand why the given value of x works. I know a similar question exists but i need to know how ($\frac {p-1}{2}$)! $^2$ $\equiv$ -1 (mod p) Any help would be appreciated, thanks


How to import Apple Mail archive files in Outlook 2013?

I need to import Apple Mail archived files in Outlook 2013 on Windows, but every time I open the import wizard and reach the file selection step, I cannot select the archived file. It doesn't even show in the dialog box.  I don't know what the issue is. Is it the file size issue as the archive file is large (about 7 GB) or there is any other fault?

Internal energy of ideal gas undergoing reversible adiabatic changes

Why is $dE=c_vdT$ valid for an ideal gas undergoing a reversible, adiabatic process? If the process is adiabatic, then there is no heat transfer, $dQ=0$, and from the first law $dE=dW$. This implies that there is work being done when changing the internal energy of the gas, ergo, that the volume changes (we don't consider work done against friction because the gas is ideal), $dW=-PdV$. However, the specific heat capacity in $dE=c_vdT$ indicates that the the change in internal energy is an isochoric process.


Ubuntu system is broken after accidentally uninstalling many packages

I accidentally removed all the packages starting with the name jpeg with:  sudo apt-get remove jpeg*   This screwed up a lot of things, removed Unity, Firefox, Flash player etc.  I somehow managed to recover the desktop and unity but then a lot of things are still buggy. For example .rpm files and .tag.gz just won't open up at all.  What I want is a way to fix everything that's amiss. Something that is the equivalent of a 'repair installation' with a windows disc.  Any tips, anyone?

Note that ubuntu-server does not have a GUI, I can only connect to it through ssh to a root user, hence it has to be done using commands.

Cannot boot from Ubuntu created USB - works on legacy hardware but not multiple windows 8 devices (Toshiba P50T, and Sony Duo 11)

I have created a bootable USB using Ubuntu running in a VMware VM and using the instructions as provided here .  I have Windows 8 hardware that 'will' boot from the USB (Sony VAIO Duo 11). Therefore, I can run boot form the USB and Try Ubuntu without any impact on my Win 8 configuration. Secure Boot setting has no negative impact either way.  I have another newer Windows 8 Pro laptop (Toshiba P50T - Haswell Architecture, 4th Gen i7) and I cannot boot from the USB. The hardware does identity the USB and provides it as a boot option, and the Ubuntu boot menu is displayed, yet the OS fails to boot.   I am inclined to believe this might be 'related' to the known USB 3.0 issues with the Haswell based systems - . The laptop in question is less than two weeks old and undoubtedly has the bug. I have booted the laptop from a fully shut down state.  Solutions/ information from someone better informed would be appreciated.


How do moving charges produce magnetic fields?

I'm tutoring high school students. I've always taught them that:     A charged particle moving without acceleration produces an electric as well as a magnetic field.   It produces an electric field because it's a charge particle. But when it is at rest, it doesn't produce a magnetic field. All of a sudden when it starts moving, it starts producing a magnetic field. Why? What happens to it when it starts moving? What makes it produce a magnetic field when it starts moving?


Is Java "pass-by-reference" or "pass-by-value"?

I always thought Java uses pass-by-reference. However, I've seen a couple of blog posts (for example, ) that claim that it isn't (the blog post says that Java uses pass-by-value). I don't think I understand the distinction they're making. What is the explanation?


Reading data from UMFT200XD or UMFT201XB

What's the purpose of Equals in IEqualityComparer

Could anyone shed a light into the problem with overriding GetHashCode with Equals? I go through a lot of articles and it doesn't seem reasonable to me. So let's suppose i have class A  public class A: IEqualityComparer<A> {     public int Field1 { get; set; }      public int Field2 { get; set; }      public bool Equals(A x, A y)     {         return x.Field1 == y.Field1;     }      public int GetHashCode(A obj)     {         return obj.Field1.GetHashCode();     } }   As far as i understood compiler get into Equals in case when GetHashCode returns the same values. But what is the real profit of it? Method Equals makes the same as GetHashCode()


First off, excuse my ignorance. I am just getting started in game dev. and ran into a little issue. So I had these weird rippling-lines going across my screen, and saw in a couple forums that this means I don't have what is called a "pixel perfect" game. To fix this, I am supposed to change the pixels-per-unit of each sprite down to 1. Currently I had it on 32 because that is my sprite size and I am a complete noob. Now, I change it down to one but it completely destroyed my game. Everything that is generated on my map/grid is sucked into the center in this giant orb of sprites (I procedurally generate my map off a grid of 1/0s). I am guessing there is just a setting or some such thing that I am missing. Any ideas? Also would be happy with an alternative to remove the rippling lines.


I have ALL the perks for enchanting (100) ALL the perks for smithing (100) and all the perks for destruction (100 again) yet I can only enchant my daedric helmet with fortify destruction to 15%.  I want to do the thing where you can get 100% fortify destruction if you doi it on four peices of apparel, however I don't know what I am doing wrong :(


Asynchronous file upload (AJAX file upload) using jsp and javascript

I am planning on having asynchronous file uploads. That is the file should be uploaded to a jsp or servlet and return something to the html/jsp page without reloading the original page. It should happen like an AJAX call. Is there any way to do it in AJAX or any other way to do it.


Calculating age by subtracting dates and showing it in DD/MM/YYYY format

I need to subtract 2 days from each other and display it in YYMMDD.  E.g.  2016-05-27 (Minus) 2015-01-15 = 1 Years, 5 Months, 16 Days   The two dates are in DATETIME format.  Many thanks!


The normal equation of the plane that contains the line $(1,1,1) + t(-2,0,3)$

Determine the equation of the plane that contains the point $(4,2,-1)$   and also the line $L: (1,1,1) + t(-2,0,3)$ for $t\in\mathbb{R}$.   The direction vector $(-2,0,3)$ of the line is also a direction vector for the plane.  We can get a vector orthogonal to the plane by solving  $$(x,y,z) \cdot (-2,0,3) = 0$$  $$-2x+3z = 0$$  One valid solution would be $(3,1,2)$.  So we have that $(3,1,2)$ is orthogonal to the plane. And since $(4,2,-1)$ belongs to it, a normal equation for the plane can be calculated this way:  $$(x,y,z)\cdot (3,1,2) = (4,2,-1) \cdot (3,1,2)$$  $$3x+y+2z = 12$$    But that's wrong. If the plane contains the line $L$, it should also contain the point  $$(1,1,1)+5\cdot(-2,0,3) = (-9,1,16)$$  But it doesn't:  $$3(-9)+(1)+2(16) = -27 + 1 + 32 = 8 \not = 12$$  What did I do wrong?


Installing managed packages to Scratch org via configuration

We've recently started adopting Salesforce DX and we're trying to figure out the best way to spin up Scratch orgs.  As of now, we have multiple managed packages from the AppExchange installed in production, including Marketing Cloud Connect and Cirrus Insight and we would like to make certain scratch orgs have them.  I know there is a way to install packages with the sfdx force:package:install command, but is there any way to do it via configuration so that we don't have to execute a certain set of commands everytime we create a scratch org?  Thanks!


When I plug in the 3.5mm jack and play back media, headphone mode keeps toggling, resulting in audio cutting in/ out every second or so. Is there a way to force headphone mode or disable the 3.5mm jack detection?  I tried a couple of apps and searched the web but people seem to want to force speakers rather than headphones, so no luck.    (Android 4.2.2 Samsung Galaxy Tab 3 Lite)


Should there be a comma between a shape adjective and color adjective?

Example:  A tall(,) green pole.   says that cumulative adjectives don't need comma. In my example, "tall" describes shape, and "green" describes color. So they are cumulative adjectives. But  says that "tall" and "green" are equivalent and coordinate adjectives ... I'm confused. Should there be a comma or not?

Removing tooltip label border completely in Leaflet.js map?

I am trying to completely remove a label boundary/border (bubble) that by default appears when using my labels of a point GeoJSON layer.   The layer I have is defined as below:  var points_layer = new L.geoJson(points, {     onEachFeature: onEachPointFeature,     pointToLayer: function (feature, latlng) {          return L.circleMarker(latlng, labelMarkerOptions);     } });   the options for the label are  var labelMarkerOptions = {   opacity: 0,   fillOpacity: 0,   fillColor:'black',   fill: 'false',   interactive: false   };  the oneachFeature function  is  function onEachPointFeature(feature, layer) {   if (feature.properties) {      layer.bindTooltip(feature.properties.v2_number.toString(), {permanent: true, className: 'labelstyle'});    } }   using the style below I was able to remove almost all of the borders around the label text but a small white triangle remains next to the label which I cannot get rid of. This somehow seems to be a svg path or something (but can determine what it really is fully or where it comes from exactly).    How can I accomplish this?  .labelstyle {       all: revert;     color: green;     font-size:14px;     font-weight: 700;     fillColor: none;     fillOpacity: 0;     background-color: none;     border-color: none;     background: none;     border: none;     box-shadow: none;     margin: 0px;     cursor: none;     direction: 'center';     interactive: false;     fill: false; }   Below is how the remaining border of the original bubble is currently looking. The White triangles to the right of the green labels is (what is there by default) and what I would like to get rid of    I do not think that this is a duplicate of   because that is where I started using the tips in there but still could not get the white triangle styled at all.   Anyone has insight how to alter my css to make the triangle disappear ?


how to get the first day and last day of current month in python

I am writing an SQL query to get the available data between the first date and last date of the current month in python. For this how can I get first and last date of current month.   Note: In the question that already asked in stackoverflow only deals with end date. Also, I want the answer as a date field like 01-03-2016 or 31-03-2016.


When I want to edit a tag of a question I get following message:     Your edit will be placed in a queue until it is peer reviewed.      We welcome all constructive edits, but please make them substantial. Avoid trivial, tiny one-letter edits unless absolutely necessary.   Now the question is: are tag edits (adding a needed tag to an under-untagged, replacing a mis-used tag) substantial enough?  For example the proc-tag-wiki is just about a Ruby feature called proc - but currenlty some questions about Oracle Pro*C (a embedded SQL preprocessor) or the Linux /proc filesystem are also tagged with proc. Btw, what tag should be used for /proc?  Say I come across a Pro*C Question which is tagged with proc - is a change to proc-sql considered substantial or not?


Is there any way to send a search query to several websites at once and browse results?  For example, I want to buy edible paper. Paper on which you can write and take a bite off for a nutritious snack. I've found about 15 websites that sell this type of paper and have a search field.  Is there any way to search all of those 15 websites at once with one single search query and view results individually later instead of going to each website manually, entering the search term 15 times?


Is work done by a person while walking negative?

When a person walks (assuming the feet don't slip), the ground is pushed backward by the foot while the force of static friction opposes the force and the foot remains stationary while the upper body moves. - This is what I've understood. However, the upper body moves - I believe, since the foot exerts a force backward and the person moves forwards, the work done by the body must be negative, while, since friction acts along the direction of motion, the work done by it should be positive. These two negative and positive forces must cancel each other out, so the net work done while walking is zero. Could someone please explain if this right or wrong?


I have installed Google Drive on Windows Server 2008 R2. When I login to the server, Google Drive starts automatically and synchrnoizes files, pulling changes down from the cloud. All good so far.  However, I would like the sync to run even if I am not logged in. Is there any way to start the sync process automatically, maybe as a scheduled task?  I have other jobs on the server which distribute the files by FTP so I would like the server copies of the files to be up to date.

Prove that $GL_2(R)$ is open in$ M_2(R)$

Prove that $GL_2(\mathbb{R})$ is open in$ M_2(\mathbb{R})$    My solution : Define the map $\phi:M_2(\mathbb{R})\rightarrow \mathbb{R}$ by sending $A$ to $\det(A)$ .  I guess $\phi$ is continuous . As $\mathbb{R}-\{0\}$ is open  $GL_2(\mathbb{R}) =\phi^{-1}(\mathbb{R}-\{0\})$ is open also open .   I would like to verify if my solution is correct .


A programming error lead to multiple insertions of identical rows in this table.  I am aware that constraints in the schema could prevent the insertions.

Problem. Suppose that $f$ has an isolated singularity at the point $a$, and $f'/f$ has a first-order pole at $a$. Prove that $f$ has either a pole or a zero $a$  This is a problem from a past qualifying exam in the institution I'm attending now which might appear in the final exam on tomorrow.(so if asking this is a problematic, then let me know, I'll delete it.)Because $f$ should have pole or removable or essential singularity at $a$, I checked that if $f$ has removable singularity at $a$ then $f(a)$ has to be $0$ to satisfy the condition in the problem, and also checked that if $f$ has pole at $a$ then $f$ satisfies the condition in the problem. So, I was trying to show that $f$ can't have essential singularity at $a$, and tried to use Casorati-Weiestrass theorem to derive some contradiction and it didn't work. I also tried to just plug in Laurent series expanded at $a$ in $f'/f$ and do calculation to eliminate some coefficients with negative indices but calculation would result infinite system of linear equations so I gave up doing it. Therefore, I'm stuck and please give me some hint.


Can this $x^2+y^2=\frac{dy}{dx}$ be solved by integrating factor method?

$$x^2+y^2=\frac{dy}{dx}$$  Originally, this is a question I asked on Quora.     Maybe this question has been solved but I was wondering if it can be done by integrating factor?  $$x^2=\frac{dy}{dx}-y^2$$  Using method of integrating factor  $$\text{I.F}= e^{\int-ydx}$$  $$\text{I.F}= e^{-yx}$$  Can it be done in this way?


Characterization of Almost-Everywhere convergence

Given a $\sigma$-finite measure $\mu$ on a set $X$ is it possible to formulate a topology on the space of functions $f:X \rightarrow \mathbb{R}$ that gives convergence $\mu$-almost everywhere?  I can't seem to find any way to write this and am suspecting that no such topology exists! Is this true?  If so, is there some generalisation of a topological space where one can make sense of convergence without having open sets?  Any comments, references or tips would be greatly appreciated.

I'm really confused.  uint8_t hash[20]; uint32_t u;  // Setting hash to some value here...  u = *(uint32_t*) hash;   This *(uint32_t*) hash causes a warning:   Dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing].   I think it's something wrong in typecasting, but I'm not sure, because I don't clearly know on how *(type*) var way of typecasting actually works. It seem to point on an object with an asterisk inside too. I am confused, that's the thing which forces me to ask a question about that. Especially I'd like to know how type* differs from *(type*). This may be a lot of help to get rid of this warning. Thanks in advance.

Creating DEM from topography map in QGIS

For my geology diploma project I need to create  DEM from topography map my professor gave me to use as a base map. The map is georeferenced. My idea was to draw lines over the izolines of the map, then specify thair elevation and then create DEM. Equidistance of the izolines is 10m. I don't know how to do it or is it even possible in QGIS.


I'm trying to find units of $\mathbb Z[\sqrt{-5}]$.  So let $a,b\in \mathbb Z[\sqrt{-5}]$ s.t. $ab=1$. if $a=a_1+\sqrt{-5}a_2$ and $b=b_1+\sqrt{-5}b_2$, then we get $$\begin{cases}a_1b_1-5a_2b_2=1\\ a_1b_2+b_1a_2=0\end{cases}.$$ First equation give us $a_1,b_1\in \mathbb Z/5\mathbb Z$ and thus $$(a_1,b_1)\in \{(1,1),(2,3),(4,4)\}, $$ but how can I continue ? I was wondering to solve the second equation in $\mathbb Z/5\mathbb Z$, but I get $a_1b_2=4b_1a_2$, but it's unfortunately not conclusive.


Biblatex cannot separate the first and the second authors

I am using biblatex for my citations as the below code shows:  \usepackage[   backend=biber,   style=authoryear,   dashed=false,   isbn=false,   uniquename=init,   giveninits=true,   maxbibnames=99,   maxcitenames=2, ]{biblatex}   By using the option maxcitenames=2, I would like to have references with more than 3 authors cited as "{First author} et al.".   For most of the references, I can get the desired citation style. However, for some references, biblatex cannot distinguish the first and the second authors. As a result, I have some in-text citations as "{First author}, {Second author}, et al.", which are very weird.   The following code show my entry in the bib file.  @article{Chiputwa2015, author = {Chiputwa, Brian and Spielman, David J. and Qaim, Matin}, doi = {http://dx.doi.org/10.1016/j.worlddev.2014.09.006}, journal = {World Development}, pages = {400--412}, title = {Food standards, certification, and poverty among coffee farmers in  Uganda}, volume = {66}, year = {2015} }   And the output that I got was "(Chiputwa, Spielman, et al., 2015)". I would like to get it as "(Chiputwa et al., 2015)".  I tried to set maxcitenames = 1, but got a similar result. So I guess the problem is the biblatex cannot separate the first two authors.


How do I pass parameter TO a Visualforce page from a link in an email?

Here's what I am trying to do:  1) User creates record A.  2) Time-based workflow sends an email to the Record A creator based on a date field in the record.  3) The email template has a URL link.  4) The URL links to a Visualforce page that is basically a form with fields to be filled out (this Visualforce page is in a managed package) and a save button that creates a new User record.  5) When the User clicks the URL link in the email, the Visualforce page opens in a new window.  6) I would like to pass the values of the fields in record A to pre-fill the Visualforce page fields.   Here's my link:  <a href="https://cs19.visual.force.com/apex/CloneThisUser?Desktop=true&Id={!Pending_User__c.User_to_CloneId__c}&formGroupInputSmall={!Pending_User__c.First_Name__c}   And here's the code from the relevant section of the Visualforce page:

           <apex:inputField html-placeholder="First Name" styleClass="form-control FirstNameInput"  value="{!u.FirstName}" id="formGroupInputSmall"/>

   I have only included the first field I would like to pass the parameter to, in order to keep this post simple.   The link passes the User_to_Clone_Id__c just fine but does not fill in the "First Name" field with the value of the First_Name__c .  What am I doing incorrectly? Thanks.

The Android OS monitors the power consumption of running apps and hardware (display). As you may guess, this is a useful feature as it allows to track down energy greedy apps.  Is there an application that would do such monitoring on Mac OS?  It should calculate the percentages of the charge that an application/process/hardware has used.  I use plenty of little software that runs in the background permanently. It would be nice to know if such little helpers drain the battery significantly.


What does "as if you were a single-classed member of that class" mean for spells known and spell slots?

Introduction  I am currently building a multiclass spellcaster, and came across this question:    This discussion appears to hinge on the phrase      as if you were a single-classed member of that class.   from p. 164 of the PHB. However, what that means is never discussed in terms of RAW. The twittersphere has produced , alluded to by @Cambio in his answer to the above question, but twitter is not a platform for discussion, and so justification was not forthcoming. Furthermore, tweets are not RAW.  So, to my specific question:  Do you determine spell slots for individual classes throughout character leveling up, then recalculate at the end (as "as if you were a single-classed member of that class" implies)? Or do you only consider one pool of spell slots as explicitly and specifically outlined on p. 164 of the PHB throughout the entire process of leveling up?   As an example, an answer would indicate how the flow of Wizard 4 dipping a level into Sorcerer at character level 5 would go:   Start at Wizard 4. Add 1 level to character as Sorcerer.   Look at number of spells known on table of p. 100.   Look at spell slots on table of p. 100 for a level 1 Sorcerer.   Determine the number of spells known is 2 and level of spell slots is 1.   Learn two level 1 spells based on the spells known of 1st level and higher  section on page 101 for the Sorcerer class.   Look at the actual spell slots of the character from the table on p. 165.    Or   Start at Wizard 4. Add 1 level to character as Sorcerer.   Look at number of spells known on table of p. 100.   Look at spell slots on table of p. 165.   Determine the number of spells known is 2 and highest level of spell slots is 3.   Learn two spells of levels 1, 2, or 3 based on the spells known of 1st level and higher section on page 101 for the Sorcerer class.


How to complete ESTA application when "THE PAYMENT STATUS COULD NOT BE DETERMINED AT THIS TIME"?

I received a payment error during my ESTA application and still need to pay. The current application status for the last few hours shows:     THE PAYMENT STATUS COULD NOT BE DETERMINED AT THIS TIME.      PLEASE CHECK BACK LATER FOR THE PAYMENT STATUS.      Your application is not complete and will not be processed by CBP until the processing fee has been paid.      You must complete payment within 7 days.   The  says to click the payment button if have not paid, however there is no payment button, I guess because already started the payment process.  I tried creating a new application however get an error about an application already existing for my passport. The application will expire automatically in 7 days, however I leave in 5 days.    I tried calling their support number but couldn't get through, and their email support has a 2-3 week turnaround time.  Any ideas how to get the visa-waiver in time? Is there perhaps a way to cancel an ESTA application so can start a new one?

Why does spd-say stop speaking after a short while in the command line?

I've noticed that whenever I'm in the command line and I try spd-say, it always stops shortly after it starts, and doesn't finish what I've told it to say.  For instance,  spd-say "moo moo farms are the best cow farms ever. They say moo, they don't pollute the earth, and they give milk. Visit moo moo farms today for only twelve easy payments of seventeen ninety five weekly!"   will only say moo moo farms are the best cow farms. They say moo, they don't pollute the earth, and they gi; and then it cuts off.  Can anyone tell me what is going on here?

Was the Sorcerer's Stone already in the Mirror of Erised when the Mirror was moved in the third-floor corridor?

In Harry Potter and the Sorcerer's Stone, the Mirror of Erised is said to be the ultimate protection against the impure of heart who desire to obtain the Stone only for their own desires.  However, the Mirror itself is not stored in Dumbledore's forbidden third-floor corridor until practically the end of the book.  Instead, it appears to be collecting dust in an unused classroom at least five floors above the kitchens, until Harry finds it and Dumbledore moves it, following their discussion.  It's assumed by the characters that the Stone is hidden underneath Fluffy in the third-floor corridor since it was moved to Hogwarts from the Gringotts vault, but given that the Mirror seems to be the only true protection against a powerful Dark Wizard, wouldn't it make more sense to hide the Stone in the Mirror from the very beginning?  Do we know anything else about whether the Sorcerer's Stone was stored in the Mirror of Erised before it was moved into the forbidden third-floor corridor?

As a noun, "abandon" is almost always preceded by the word "reckless".

Feel free to correct me if you don't share the same experience, but in my own experience, usage of the word "abandon" as a noun without being apart of the phrase "reckless abandon" is extremely rare.  Is there a name for this situation where a noun is almost exclusively paired with the same adjective and is it a unique phenomenon?


Can I install / downgrade to Mojave on a new MacBook Pro 2020 that comes with Catalina?

I'm planning on buying a new 16-inch MacBook Pro. However, it will come with Catalina, and I still rely on several 32-bit apps. I was wondering if it's possible to downgrade to Mojave?  I was thinking maybe through a Time Machine backup... I've restored from Time Machine before to downgrade from High Sierra to Sierra. Would it be possible to set up the new computer from a Time Machine backup with Mojave?  I'm worried the new hardware would not accept an older OS...  Thanks

Understanding minipages - aligning at top

I would like to be able to align two minipage at the top, without worrying about what is in the minipage.  I am aware of the optional [t] parameter, but still have some confusion as to how this all works.  I tend to think of a minipage as a regular page in that whatever is placed on it starts at the top and fills the page going across and then down the page, but this does not appear to be the case.  In the MWE example below, I have color coded the sections for reference purposes.   The first case (black) works just as I would expect. The two minipages are aligned exactly as I want with the [t] specifier.  No question here.  The next case (red) only works if the inner minipage also has the [t] specifier. Why is that necessary?  I would have thought that any content would be placed at the top of this page, and since both the outer minipage had a [t] things should have aligned at the top. I would like to place a graphic in the second mini page, and still have the two aligned at the top.   The simple case (blue) of using \includegraphics directly does not result in the content being aligned at the top.  So, then I attempt to put this in a \parbox (green) and this too does not yield the desired results.  I also try to place the graphic inside an inner minipage (brown) and specify the [t] alignment, and even though this worked in the red section, it does not here.  The only difference between the red and brown being that the red section had text, whereas the brown section has a graphic.  I am aware of question regarding  which suggests to place \vspace{0pt} at the top of the minipage, and that does provide the desired alignment (cyan), but adds vertical space at the top.  So, my second question is why is the \vspace{0pt} necessary when a graphic is included, but not when it is text.  This appears to be a hack and wondering if there is a replacement for minipage that works better without having to worry about exactly what is in the minipage?  Also, why did wrapping the figure in a parbox (green) or another minipage (brown) not solve this problem?   Here is the MWE:  \documentclass{article} \usepackage[demo]{graphicx} \usepackage{lipsum} \usepackage{xcolor}  \begin{document} \section{This Works - Aligned at top as desired} \begin{minipage}[t]{0.6\linewidth}     \lipsum[1] \end{minipage} \hfill \begin{minipage}[t]{0.3\linewidth}     \lipsum[2] \end{minipage}  \color{red} \section{Why does inner mini page required the [t]?} \label{Minipage-in-minipage} \begin{minipage}[t]{0.6\linewidth}     \lipsum[3] \end{minipage} \hfill \begin{minipage}[t]{0.3\linewidth}     \begin{minipage}[t]{\linewidth}% Why is [t] required here         \lipsum[4]     \end{minipage} \end{minipage}  \color{blue} \section{Why are These not aligned at top?} \begin{minipage}[t]{0.6\linewidth}     \lipsum[3] \end{minipage} \hfill \begin{minipage}[t]{0.3\linewidth}     \includegraphics[width=\linewidth]{foo} \end{minipage}  \color{green} \section{Why are These not aligned at top?} \begin{minipage}[t]{0.6\linewidth}     \lipsum[3] \end{minipage} \hfill \begin{minipage}[t]{0.3\linewidth}     \parbox{\linewidth}{\includegraphics[width=\linewidth]{foo}} \end{minipage}  \newpage \color{brown} \section{Why does this not work with the [t] as it did in red section?} This worked fine in Section \ref{Minipage-in-minipage}  \begin{minipage}[t]{0.6\linewidth}     \lipsum[3] \end{minipage} \hfill \begin{minipage}[t]{0.3\linewidth}     \begin{minipage}[t]{\linewidth}% Even with [t] here, this does not work         \parbox{\linewidth}{\includegraphics[width=\linewidth]{foo}}     \end{minipage} \end{minipage}   \color{cyan} \section{Adding a \textbackslash{}vspace\{0pt\} works} \begin{minipage}[t]{0.6\linewidth}     \vspace{0pt}% Hack!! But does do the job     \lipsum[3] \end{minipage} \hfill \begin{minipage}[t]{0.3\linewidth}     \vspace{0pt}% Hack!! But does do the job     \begin{minipage}[t]{\linewidth}% Why is [t] required here         \parbox{\linewidth}{\includegraphics[width=\linewidth]{foo}}     \end{minipage} \end{minipage} \end{document}

How can the US immigration officials know one has visited Iraq, Syria, Iran, or Sudan?

Now that  is in effect, people who have visited Iraq, Syria, Iran, or Sudan since 2011 are banned from entering the US under the Visa Waiver Program. However it's unclear to me how could the US officials prove one has set foot in those countries, unless:   There's a stamp in one's passport indicating so, which can be side-stepped by getting a fresh passport One mentions the fact on the ESTA application form, which is obviously easy to avoid   Is there any other way the US might be able to identify such individuals?  NB: I'm not eligible for the VWP myself and don't plan to travel to the four countries above, so it's a purely theorethical question


Why does $i^i$ equal more than one number?

As I understand it, $i^i$ returns more than one real number. Why does this happen? When I raise $i$ to $i$, I'm raising a specific number to itself. So why do I get multiple values of this, as if it was, for lack of a better word, some sort of a "function"?  EDIT: My question wasn't "why is $i^i$ real". I know it's real. Furthermore, I know how to calculate $i^i$. I was just looking for intuition as to why this number has multiple values.


How to determine similarity between histograms? (Which metric to use?!)

Hello Stack Exchange community,  I'm relatively confused on what to do in this scenario. I am running an experiment that retrieves data of interest and stores it as an array. Experimental conditions are slightly different, and for my specific application, it is important to measure heterogeneity of my data. I was asked to use a distance metric for my 2D histograms generated post data analysis.  However, there are a wide array of options available after doing a literature search. There is the "Earth Mover's Distance", the Jensen-Shannon metric (the square root of the Jesen-Shannon divergence value), Bhattacharyya distance, Minkowski distance, etc.  I understand that these distances are defined differently, quantitatively speaking, and thus have difference implications, but for my example, what seems to be an efficient metric at quantifying differences in histograms (i.e, getting to the end goal of assessing heterogeneity)?  Thank you


Disable all splash graphics/texts on startup and shutdown?

I have LUbuntu running on a special device which runs a single program on startup and ever. I only need the user to see the splash of my program. BIOS has been taken care of. Now for the rest. What do I need to do?  I found this suggestion: sudo mv /etc/init/plymouth-splash.conf /etc/init/plymouth-splash.conf.disabled But all it did was show nothing until I press something and LUbuntu shuts down...


Zeppelins, altitude record and weird creatures

I'm trying to remember a book I read a while ago.  A lot of it was focused on zeppelins, that use a gas with a really specific smell you could detect easily (was it strawberry ? or blueberry?). The main protagonist is a boy, he's aboard a big luxury zeppelin that crashes on an island, maybe due to a storm, and can't go back because the envelope has lost gas.   There's also something about going on very high altitude with a zeppelin, so high that is almost non-breathable, and everything freezes. At that altitude, the protagonist(s) find a abandoned zeppelin, populated by some octopus-like creatures, which can deliver an electric shock with their tentacles.  I would say the book would be from the mid 2000's, when I read it, and for me it looked like a pretty recent book at the time.


Since I upgraded my MacBook Pro(mid-2012) to macOS Sierra the voice which is being used by Siri is unnatural.It sounds like the old iOS 6 Siri.I downloaded all the dictation voices but the problem persists.Somwhere on the internet I found a solution saying that enabling checkboxes under App Store auto-update fixes the issue but Siri still sounds the same.Does anyone have a concrete solution?


So I'm creating a beamer on overleaf (it's a site that lets you write in LaTeX and compile it automatically and then download a PDF of your work), and I'm wondering how I can make it so that when viewing the beamer I can make different lines on the same frame appear at different times, progressively ?  Like the first two lines would appear, then the third, then the fourth and fifth and so on.  The obvious way is to "duplicate " the frames, each frame being copied as many times as needed, but only the first two lines would appear on the first copy and so on. But I was wondering if there could be a more subtle approach, some built in functions etc.

I have 3 URLS that serve the same data:   www.example.com/product/foo www.example.com/product/foo?id=1 www.example.com?product=foo   For Google's sake I want the URL www.example.com/product/foo to be the canonical one.  However, I have my code setup so all 3 of those pages are served from the same code so if I add in <link rel='canonical' href='http://www.example.com/product/foo' /> to my code it will be applied to all 3 pages, including the one http://www.example.com/product/foo.  Is there any issue with doing this or does having a circular canonical not cause any issues?


Let $G$ be a group such that $|G| \ge 3$ then $|AutG| \ge 2$.  How can I approach to this problem?  It is necessary to divide in cases? For G finite and infinite, or Abelian and non-Abelian?  The Lagrange theorem can help me?  Could you suggest some hints?


Central limit theorem on distributions with support other than $\mathbb{R}$

Let $X_1,\dots,X_n \overset{iid}\sim exp(1)$.  But then $\bar{X}$ is supposed to approach a normal distribution?  I agree that the skewness will slow such convergence, but that isn't my issue. The exponential distribution does not have support on the negative numbers, so $P(\bar{X} <0) = 0 $. It's not that the probability too small for software to calculate. The probability is zero.  Ditto if $X_1,\dots,X_n \overset{iid}\sim U(0,1)$ or $\chi^2_2$.  So what's going on?  What I can reason is that the distribution for finite $n$ never has support on all of $\mathbb{R}$ like a normal distribution does. However, when we "get" to $\infty$, we get support on all of $\mathbb{R}$. This reminds me of the Cauchy sequence of rational numbers 3, 3.1, 3.14, 3.141,... converging to the irrational $\pi$.


Cycles is only rendering sky texture and nothing else

I was in Blender Cycles, I imported an .obj file, worked with it, added some materials to it, and clicked on the little "render" circle right next to Object Mode. I saw the building and the sky and that was what I needed.  When I went to render image, the sky was only in the background, not the building.

Strange behavior of left arrow key in excel 2013

I saw someone else had this question for Excel 2010, but it was never properly answered and I will be more specific as to what is happening.  In Excel 2013, only when I am working on a PROTECTED sheet, if I have cell A2 selected and try to use the left arrow key, instead of stopping at A1, it cycles the selection all the way over to AU2!  I've also tried the suggestion to simply use the "home" key to go to the beginning of the row, however, it does not take me to A2, it takes me to E1.   Can anyone help with this??


I have a charger light. It gets charged by 220V AC supply. It can light 5 LEDs. I know that it needs to make the supply 220V AC to DC of lower voltage nearly 5V to 10V. Then it can charge the small battery. But I found no transformer in the circuit. There are simply some diodes resistors and capacitors.   I want to know how the circuit works. I want to know how the small battery can be charged with so high voltage?
