Why dont i have a .minecraft folder on my windows 10 laptop?
Where does Minecraft for Windows 10 store its data?
Does the Planck scale imply that spacetime is discrete? From this , I now understand the gradient to be the directional derivative that returns the steepest slope at a point. However, reading my textbooks, they all say that the gradient is normal to the tangent plane. In the above SE question, the gradient sounds like it should be parallel to a direction in the $xy$ plane, not actually up on the surface.   My question is therefore do I have a misunderstanding of the tangent plane, gradient or directional derivative?   In addition, I question how the gradient always passes through the origin or the $xy$ plane? If for instance in the graphic, the gradient had been another direction (say horizontal), then it wouldn't pass through the origin! In addition, the gradient of other points in the graphic would satisfy this example. Many thanks! Can I change a user's keyboard input? SSL certificate for a public IP address? I just tried buying a Comodo Positive SSL but it was rejected due to not supporting a public IP address, but instead they only support a domain name.  Does anyone know any SSL certificate provider that supports public IP address instead of a domain name?  My company has a dedicated server hosted with a web hosting company, which is used for running a bugtracker for multiple projects (for multiple clients). Since it's only used for a bugtracker, we don't need a domain name (our clients access it by typing the public IP in their browser). How do I get my C# program to sleep for 50 milliseconds?  This might seem an easy question, but I'm having a temporary brain failure moment! I have a CSV with an address field (no lat/long), so I went to Google My Maps, imported the csv and geocoded of the records.  Now I export the layer as KML and added the KML to QGIS and Google Earth Pro, but in non of them I can see the markers. In fact in QGIS, the KML layer is added as datatable (no geometry).  What's happening? How can I export a geometry layer from google My Maps? I want to determine $$\lim\limits_{(x,y) \to (0,0)} \frac{x^2·y^3}{x^4+y^6}$$  I'm sure the limit exists, it's zero because I tried to find other different limits in line and parabola points ($(x,mx)$ and $(x,mx^2)$) but every time I got zero. So, I have to use the definition or sequences to confirm. Is irrational times rational always irrational? Is an irrational number times a rational number always irrational?  If the rational number is zero, then the result will be rational. So can we conclude that in general, we can't decide, and it depends on the rational number? Classify all groups with order $pq$, $p$ is not equal to $q$ I am reading the following material:  . At page 5, there is a proof classifying all groups with order $pq$(they are all primes and $p$ is not equal to $q$). I am lost in the last two sentence, which claims the semidirect product are all isomorphic. Could someone help me to understand it? Thanks! I have a table with a varchar(max) column that stores text ~4-10KB in size. Data is just being added - never modified, it is a log. My problem is that a table grows too large in size - I would like to keep about 1000000 rows in this table.   I am limited to SQL Server Express and hit the limit on database size. Compression is not available in SQL Server Express and I afraid that Filestream may not be appropriate and the number of files would be too big.   What is the best solution in this case? If F is a finite field, then $F^F=P_F$. The standard font packages make global changes to the fonts in my document. What if I want to use a particular font for just a portion of my text?   How do I find the right name of the font? How do I select the font? How do I restrict the scope of the font change?     There are separate answers for different flavors of TeX (quick links): is there any way to decode string? Is it a wise-decision to buy full-frame lenses for use on an APS-C body? I have a Canon 550D which I've been using for around a year now. I really love it and have learned a great deal with this and the 18 - 135mm kit lens. But now with experience I feel the need to get some better glass. I won't be buying a new body any time soon because I figure investing in some good glass is more important.   As I have looked around, I see quite a few good used L lenses I can get in ebay for good bargain prices. But I know that the EF lenses don't have the same focal length in the cropped sensors. Is it a wise decision to buy these EF lenses or buy the cropped sensor alternatives?  I have the following lenses in mind that I am looking to buy down the line from the canon range over the next several months.  16-35mm f/2.8L, 24-70mm f/2.8L, 70-200 f/4L.  Are these apt choices for cropped sensors? I know most pros with FFs use these but I am a bit skeptic that they will serve the same purpose for me. If so what are the alternatives for this that have almost as good image quality? Cortana Search is not finding applications on Windows 10 For the past several versions (since Windows Vista, I think), if you hit the Windows key and start typing, Windows will search for applications.  Since upgrading to Windows 10 with , she is only hit or miss at finding applications. And she doesn't do partial searches, either.  Some examples:   WinKey + type "Paint" does not find "mspaint". Instead it suggests some applications from the store. WinKey + type "Excel" does not find Excel. Nor does typing "Word" find Word. However, typing OneNote finds OneNote.   What is the reason for this behavior and how I can get Cortana to find the applications installed on my machine again? Is there a setting I am missing?    If I browse to "C:\ProgramData\Microsoft\Windows\Start Menu\Programs" I can see that the shortcuts for these applications all still exist. But Cortana is not finding them. Everything from the Microsoft Office applications to  to  to hundreds of other applications I have installed.  Where can I set which folders Cortana indexes?    As you can see in the screen shot below, this Start Menu folder is, indeed, indexed:    However, none of these applications are coming back as search results from the "start" menu.  It may be related to  as well.  I did a brand new install of Skype (for desktop), and it shows up nowhere in the start menu. And typing in "Skype" to search for the application does not find it. But the shortcut to Skype is definitely in this location:  C:\Users\Patrick\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Skype     EDIT  The latest Windows 10 update (Threshold 2) has solved this issue for me. Cortana now finds all my files with no issues. Previously my only solution was to use , I've been able to uninstall that now and use the standard Windows Start menu. The wavefunction $\Psi(x,t)$ for a free particle is given by  $$\Psi(x,t) = A e^{i(kx-\frac{\hbar k}{2m}t)}$$  This wavefunction is non-normalisable. Does this mean that free particles do not exist in nature?  Why then do we use free particles $\psi(\vec{x}) = e^{ikz}$, for example, in scattering theory? Math mode in tabular without having to use $...$ everywhere I have a file with ANSI colors.  test.txt: \e[0;31mExample\e[0m  I would like to display the content of this file in a terminal, like cat does, but I would like to display the colors as well. Object referencing its own property on initialization Adding CSS Reference on Site Page So I have created a Site Page that has the "New Experience" look and I would like to change its style a little. Nothing major, just the height, width, color, etc. However, I can not seem to figure it out.   For example, I tried to change the height of the .pageHeader to a smaller value.   .pageHeader{ height: 150px !important } //for example of CSS in file   Here is a reference image of the page i'm trying to change    I tried adding   &lt;link href="../SiteAssets/file.css" rel="stylesheet" type="text/css"&gt;   to the .aspx page using SharePoint Designer and it didn't work.    I also tried adding   &lt;SharePoint:CssRegistration ID="CssRegistration" Name="SiteAssets/file.css" runat="server" /&gt;   to the .aspx page and it didn't work    I tried to use the "Embed" feature to add the CSS; however, it complains and says,     This embed code doesn't seem to work. We only support iframe based embeds.   Question:   How can I add custom CSS to this type page?  I can't seem to figure it out and I'm not sure exactly why the page will not load the file.  Is this even possible?
