Ok, so I was trying to edit files in the the WindowsApps directory (I made this post ) and I set myself as the owner of all of the folders in this directory. Then, this made Windows Store unlaunchable, so I began fiddling with the permissions, which was a big mistake. If I add a permission rule giving "All application packages" full control of the WindowsApps folder and subfolders, then Windows Store begins functioning again, but this seems like a band-aid fix so I tried to find another solution. I tried resetting Windows twice (once keeping files and once losing files) but this issue still persists.  I am running 64-bit Windows 10 Pro - I am preparing to reinstall Windows with a USB drive created through the  but I am worried this will install a standard version of Windows. Will I be able to keep the Pro version?   Does anyone have any other ideas - maybe ways to reset permissions of an entire folder tree or is there a way to delete the entire WindowsApps directory and have Window update repair it?  At this point, I am considering just using my computer as-is, because I don't really use the Windows store.. please help!
I had to take ownership of the special folder C:\Program Files\WindowsApps to fix . The issue is now resolved, so I'd like to reset the permissions to the way they were before I took ownership of the folder.  I reverted NT SERVICE\TrustedInstaller to the owner and removed my account's permission entries:     But I still have full control of the folder and can browse the folder in Explorer without getting the usual warning that I would have to take ownership:     Is it possible to restore the default permissions of this folder?
Is it possible to have two background images?  For instance, I'd like to have one image repeat across the top (repeat-x), and another repeat across the entire page (repeat), where the one across the entire page is behind the one which repeats across the top.  I've found that I can achieve the desired effect for two background images by setting the background of html and body:  html {     background: url(images/bg.png); }  body {     background: url(images/bgtop.png) repeat-x; }   Is this "good" CSS?  Is there a better method?  And what if I wanted three or more background images? Is there a term denoting the writing of words using numbers instead of letters? How to represent it with UNIQUE indexes and foreign keys? "Group" is a group of pupils. "Topic" is a topic of lessons.  To every group corresponds exactly one topic. (So there may be multiple groups per topic.)  To a pupil corresponds multiple groups, but maximum one group per topic.  How to implement this in terms of UNIQUE indexes and foreign keys in MySQL? How do I get the full url of the page I am on in C# I have the name of a function in JavaScript as a string. How do I convert that into a function pointer so I can call it later?  Depending on the circumstances, I may need to pass various arguments into the method too.  Some of the functions may take the form of namespace.namespace.function(args[...]). How can I prove that $2017 \mid 1^{2017}+2^{2017}+\dots+2017^{2017}$? I tried proving it with the use of modulo, however it was to no avail. Afterwards, I  tried researching, for possible theorems, that may help, but that bore no fruit, either. Can you guys please help me proving it, as I am stuck? Thanking you in advance. Problems with macOS path on Synology NAS (SMB) I am having issues with macOS where, after mounting a drive it will mount new drives instead of just jumping to the sub-folder path within the mounted drive.   For example, I'm seeing where I send someone a path for in the "Video" drive on a Synology (smb://HAL9000/Video).  Instead of mounting the "Video" drive (smb://HAL9000/Video) and going to a sub-folder within the video drive labeled "GoPro -IMPORT", it will create a new drive on their desktop labeled "GoPro - IMPORT".    If I create a new sub-folder within "GoPro - IMPORT" and send them a link to that like (smb://HAL9000/Video/GoPro%20-%20IMPORT/Test), instead of taking to the sub-folder in the "Video" drive that they already have mounted on their desktop, it will create an entirely new drive labeled "Test" on their desktop.    I've tried reaching out to both Apple and Synology and had no luck with this.  I would appreciate any kind of help/support. How to update to the latest numpy and scipy on Ubuntu 14.04LTS On my Ubuntu 14.04LTS, for python3, I have   &gt;&gt;&gt; import numpy  &gt;&gt;&gt; import scipy  &gt;&gt;&gt; numpy.__version__  '1.8.2'  &gt;&gt;&gt; scipy.__version__  '0.13.3'   I want to update numpy and scipy to the most , I tried with the following commands  sudo pip3 install --upgrade numpy sudo pip3 install --upgrade scipy   both commands ran successfully, but the version numbers didn't change to 1.9.2 and 0.16.0 at all for both python packages (after restarting the computer). Anyone knows how to update to the most version? Thank you very much!! Prove the compactness of a set B We have $A=\left\lbrace 2019,1010,\ldots,(n+2018)/n,\ldots \right\rbrace$ and $B=A \cup \left\lbrace 1 \right\rbrace$  How can I show directly (that is, not using the compactness criterion in $\mathbb{R}$) that every open cover $G$ of $B$ admits a finite subcover?  moreover, I know that $A$ is not compact and I am aware that I would need a single example to prove it, any hint on how to find an open cover of $A$ that does not contain a finite subcover?  My first thought was to choose the set of all neighborhoods with radius r centered around each point of A but apparently this is wrong and I do not understand why. I'm answering a question with a suggestion to use rename, and I realize I don't know what package it comes from (as part of the answer, I imagine saying something like "if you don't have rename, it's installed as part of [package]").  man rename tells me to SEE ALSO: mv(1), perl(1) - so my first thought is that it was installed with perl.  A related answer, , helps me figure out that the perl package includes prename but not rename - and it turns out that my /usr/bin/rename points to /etc/alternatives/rename which points to /usr/bin/prename  So this is still kind of confusing.  Did /etc/alternatives/rename point somewhere else before I installed perl?  Is there a general way to tell which package something comes from?

In logic, a semantics is said to be compact iff if every finite subset of a set of sentences has a model, then so to does the entire set.   Most logic texts either don't explain the terminology, or allude to the topological property of compactness. I see an analogy as, given a topological space X and a subset of it S, S is compact iff for every open cover of S, there is a finite subcover of S. But, it doesn't seem strong enough to justify the terminology.   Is there more to the choice of the terminology in logic than this analogy?

Google news results have an acompanying thumbnail next to articles that show up in the results.    If Google's crawler can't find a thumbnail to pull from our site, it uses its next best guess from another site, therefore linking the image to another site but still uses our headline.  Example:  Headline from Reuters, Image from Livemint:   Our pages absolutely have images, they are not massive in file-size or dimensions, yet we are not having them pulled / crawled correctly.  We have read up on the suggestions from Google, and from others around the web and nothing is panning out.  Has anyone had any experience where they can ensure Google news will pull a thumbnail of our choosing? If photons have no mass, how can they have momentum? As an explanation of why a large gravitational field (such as a black hole) can bend light, I have heard that light has momentum. This is given as a solution to the problem of only massive objects being affected by gravity. However, momentum is the product of mass and velocity, so, by this definition, massless photons cannot have momentum.  How can photons have momentum?   How is this momentum defined (equations)? Let $A ∈ M_{m\times n}(\mathbb{Q})$ and $B ∈ \mathbb{Q}^m$. Suppose that the system of linear equations $AX = B$ has a solution in $\mathbb{R}^n$. Does it necessarily have a solution in $\mathbb{Q}^n$?  Where do I start?    I feel I can use this to :  $$x_i=\frac{1}{a'_{ii}}\left(b'_i - \sum_{j=i+1}^{k} a'_{ij} x_j \right).$$    Here is a thought that just crossed my mind, but I'm not sure if this is legal:  Suppose $Y\in \{\mathbb{R}\setminus \mathbb{Q}\}^n$ and $Y'\in\mathbb{Q}^n$ are solutions to $AX=B$. Then $AY=AY'=B$, or $A(Y-Y')=A(Y+(-Y'))=0$, but  addition between $\{\mathbb{R}\setminus \mathbb{Q}\}^n$ and $\mathbb{Q}^n$ is . . .
