I have exceeded my account registration, (which is one), and I want to reset all of my Minecraft settings - I want everything deleted except Minecraft itself because I still want to play on servers.   So I need to know how to wipe out Minecraft out or delete previous account registrations.
When I open the game, the screen stays at the Mojang sign and then crashes. It has something to do with my texture pack, but I can't start the game to change it and it won't let me delete the texture pack folder alone.  I've already deleted the bin and resources folders in the minecraft folder and downloaded the game again. I opened it but the same problem was still there.  How do I properly perform a clean uninstall of the game?
Mental estimate for tangent of an angle (from $0$ to $90$ degrees) I haven't been able to find my favorite questions in the official Stack Exchange Android app.  Looking at my accounts page gives nothing on them. Why would a JavaScript variable start with a dollar sign? pattern of moving electrons in wire under AC Is there a particular reason why vote times are omitted in the data dump?  IMO this could be a very useful data-set. Is this one of the steps that was done to anonymize the data, or does it simply not exist? This would be a very good addition to future dumps to help build time-based relationships, which are currently very rigid and full of assumptions. I think this is a basic question, but it's hard to wrap my head around. How to check if a row exists in MySQL?

Update help center on syntax highlighting to point to an actual list of options Reading the help center article on syntax highlighting, one of the paragraphs within it reads:     You can use either , like lang-cpp or lang-sql, or you can specify a tag, and the syntax highlighting language associated with this tag will be used:   Note the link in there, which goes to .  Problem is, a long time ago we removed the list of options from several questions/answers across meta Stack Exchange because it was a pain trying to keep all of them updated. It makes a lot more sense to just have one list that we keep updated, and the most logical place for that list was in the , which is where it now resides.  Can the link in the help center be updated to point directly to the list, rather than to a post that explains that the list has been moved? How to close/open a view panel I can't find a way to close a view panel, in particular the horizontal at the bottom, is pretty useless to me at this moment. Why isn't my Gravatar image updating? ubuntu terminal is not working properly in vi editor I'm currently building a sitemap for my web app.  Note: my app is a single page app built with React and Firebase.  Basically I wan to index blogPost and product pages. So I intend to generate my sitemap dynamically (on server). It's a small website (around 500 pages).  I want to build something like this:  &lt;urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"&gt;   &lt;url&gt;     &lt;loc&gt;       https://www.myproject.org/blog/some-blog-post-slug     &lt;/loc&gt;     &lt;lastmod&gt;2019-11-14T20:22:43.502+00:00&lt;/lastmod&gt;     &lt;changefreq&gt;weekly&lt;/changefreq&gt;     &lt;priority&gt;0.8&lt;/priority&gt;   &lt;/url&gt;   &lt;url&gt;     &lt;loc&gt;       https://www.myproject.org/dp/some-product-slug     &lt;/loc&gt;     &lt;lastmod&gt;2019-11-15T13:08:52.127+00:00&lt;/lastmod&gt;     &lt;changefreq&gt;weekly&lt;/changefreq&gt;     &lt;priority&gt;0.8&lt;/priority&gt;   &lt;/url&gt; &lt;/urlset&gt;   And I keep the following properties in my database, both for blogPosts and products:  createdAt: &lt;Timestamp&gt; lastModifiedAt: &lt;Timestamp&gt;  // UPDATED EVERYTIME I UPDATE THE RECORD   And I'm thinking about using my lastModifiedAt value as the &lt;lastmod&gt; tag for the sitemap.  So far, so good! Everytime I update my blogPost or product objects in my database. The next time the sitemap is requested, the new modifiedDate will show on those that have been changed.  QUESTION  But what if I make a change not in the database itself, but in the way I render all the product pages, for example.  Imagine that I've added some structured data tags to display rich results on google, with price, reviews etc. So my product info is the same, but from that point on, all of my product pages will render those extra tags that I need to be re-indexed.  Example (add a structured data tag with the product price):   &lt;div property="schema:price" content="119.99"&gt;&lt;/div&gt;   In that situation, will I have to update all &lt;lastmod&gt; for all the products? How Google will know that it needs to re-crawl those pages and be able to see the structured data tags?  What if I change only the styles for the productPages? Do I have to update the &lt;lastmod&gt; for every product in this case? Isomorphism of a product $C_n \times C_m$ of cyclic groups with the cyclic group $C_{mn}$ Given that $C_n$ is a cyclic group of order $n$, what conditions must integers $n$ and $m$ satisfy such that the group $C_n \times C_m$ is isomorphic to C$_{mn}$?   So I attempted to investigate a few lower-order cyclic groups to find a pattern. In particular, I looked at $C_2 \times C_3$ and compared it to $C_6$. Here are a couple of diagrams:  $C_2 \times C_3$ -   $C_6$ -   They Cayley tables look pretty different (identity elements are all over the place for $C_2 \times C_3$) so I concluded that they are not isomorphic.  I did the same for $C_2 \times C_4$ and $C_8$:  $C_2 \times C_4$ -   $C_8$ -   Again, I arrived at the conclusion that the 2 groups are not isomorphic due to their Cayley table structure.  It seems I'm stuck now. Are my conclusions wrong for the examples I examined? If so, how do I find the conditions for the general case of comparing $C_m \times C_n$ with $C_{mn}$? gnome maps program never runs I have this problem while running GNOME Maps ~$ gnome-maps  (org.gnome.Maps:10414): Gjs-WARNING **: 19:43:34.553: Some code called array.toString() on a Uint8Array instance.
