Uninstall kubuntu-desktop I installed kubuntu-desktop using sudo apt-get install kubuntu-desktop but I no longer want to use KDE.

For three days straight, I have connected to the public WiFi network at my local library. Each day, I have seen a different prompt in Terminal. Here are some of the prompts I've seen:  zp-pc:~ russell$ mary-pc:~ russell$ normob05:~ russell$   I have check under System Preferences -> Sharing, and my computer name is "Russell's Mac". Also, I set the DHCP Client ID to "RUSSMAC" under System Preferences -> Network -> Advanced -> TCP/IP, but I still see the random host names at the Terminal prompt.  Why is my computer name changing every day? I really get confused when to use say and when to use tell. Which is appropriate in the following:   What did he tell? / What did he say?

Why is there a discrepancy in disk usage reported by df and du? I have a Linux CentOS server, the OS+packages used around 5GB. Then, I transferred 97GB data from a Windows server to two folders on this Linux server, after calculated the disk usage, I see the total size of the two folders is larger than the disk used size.  Run du -sh on each folder, one use 50GB, the other one use 47GB  But run df -h, the used space is 96GB. (50GB + 47GB + 5GB) > 96GB  Is there any problem? Those two folders contain lots of files (1 million+). Thanks. Why is "letter" not plural in "two letter words"?

Is it better to have an ErrorDocument 404 redirect back to the homepage or a standard 404 error page? Is it bad to marinate meat for too long? From my experience it is always best to marinate meat for a decent amount of time, so the meat can "soak" up the marinade and be more flavourful.  However, I came across this recipe here:   In the directions, it says: Add pork and marinade for a minimum of 6 hours or overnight, but no longer than 12 hours.  I was wondering, why does it say "no longer than 12 hours"? Isn't it good to let meat marinate for as long as possible?  Thanks.

Ratio test and the Root test White background with filmic blender Why I think tension should be twice the force in a tug of war I am able to successfully use wp.hooks.applyFilters() and wp.hooks.addFilter(), but I'm not able to render a React Component using wp.hooks.addAction(). However, the console.log() runs just fine within the callback for an action. This is my code:  import { createHooks } from '@wordpress/hooks';  let globalHooks = createHooks();  const Header = () =&gt; {     return (         &lt;h1&gt;Header Component&lt;/h1&gt;     ); }  const RevisedHeader = () =&gt; {     return (         &lt;h1&gt;Revised Header Component&lt;/h1&gt;     ) }  export default class App extends Component {      constructor( props ) {         super();          globalHooks.addFilter( 'replace_header', 'revisedHeaderCallback', this.revisedHeaderCallback );         globalHooks.addAction( 'after_replace_header', 'afterRevisedHeaderCallback', this.afterRevisedHeaderCallback );     };      revisedHeaderCallback( header ) {         return &lt;RevisedHeader /&gt;;     }      afterRevisedHeaderCallback() {         return &lt;RevisedHeader /&gt;;     }      render() {          return(             &lt;div className="App"&gt;                 { globalHooks.applyFilters( 'replace_header', &lt;Header /&gt; ) }                 { globalHooks.doAction( 'after_replace_header' ) }             &lt;/div&gt;         );     } }
