The page in question:   I want to change this image in the #header from    to this new image    Is there a way to do it by pasting code in the console panel? (client side)  I tried:  var header = document.getElementById("header"); header.style.backgroundImage = 'url(http://i.imgur.com/htDLyzu.png)  no-repeat!important';
Title pretty much sums it up.  The external style sheet has the following code:  td.EvenRow a {   display: none !important; }   I have tried using:  element.style.display = "inline";   and  element.style.display = "inline !important";   but neither works. Is it possible to override an !important style using javascript.  This is for a greasemonkey extension, if that makes a difference.
Wrong favicon displayed on Google's mobile SERP For some time now, Google has been displaying a website's favicon next to its title on the mobile SERP according to    But, for one website that I am managing, it is showing a completely different favicon. You can see it if you open the  on a mobile device, I am talking about the orange one:  I am referring to the top result.  As you can see on the , the favicon has been added correctly using the proper meta tag:   &lt;link  rel="icon" type="image/x-icon" href="https://www.hoofgroove.ch/pub/media/favicon/default/favicon.ico" /&gt;   This is according to .  Also, all the browsers are displaying the correct favicon, which is not the orange one but the black&amp;red one.  This meta tag has been used for weeks and also the  has always been the correct one as far as I can tell.  But for some reason, Google is showing the wrong favicon on its mobile SERP.  Any ideas why? Finding the limit of $(1-\cos x)/x^2$ Multiple workspaces on Ubuntu 18.04.1 LTS and later with GNOME Shell When running umount /path I get:  umount: /path: device is busy.   The filesystem is huge, so lsof +D /path is not a realistic option.  lsof /path, lsof +f -- /path, and fuser /path all return nothing. fuser -v /path gives:                    USER        PID ACCESS COMMAND /path:            root     kernel mount /path   which is normal for all unused mounted file systems.  umount -l and umount -f is not good enough for my situation.  How do I figure out why the kernel thinks this filesystem is busy? How many levels are there for Steam Trading Card badges? With the new Steam Trading Cards, I decided to craft the badge for CS:GO.

Google isn't surfacing Events rich snippets in SERP when JSON-LD Structured Data is valid Google confirms our site has thousands of valid MusicEvent structured data objects presented using JSON-LD, as indicated in the Structured Data section of Webmaster Tools. However, rich snippets for the events do not show up in any search result pages. The Rich Cards tab in Webmaster Tools says:     We did not find any structured data for rich cards on your website.   The structured data is valid with no errors in the Structured Data Testing Tool. We do generate some warnings occasionally for missing endDate and price fields. Comparing our code to a survey of other sites whose rich snippets do appear, we are not doing anything unique in terms of our markup.  The data has been there for months, in fact over the months we've tried also using Microdata format. The Structured Data section indicates that many pages were crawled this week.  Besides SDTT validation, what else can I check to troubleshoot this issue? "If I would have lost you" vs "If I had lost you" I watched a (Hollywood?) film the other day where a character visiting his just-hospitalised wife (who it seems will actually survive) says "If I would have lost you [I don't know what I'd do]".  I'd always thought this was an error made by non-native speakers (I myself would only expect "If I had lost you"), but there was nothing to suggest that in the movie. Is it a regionalism?  EDIT: Actually, that wasn't true about only expecting "If I had lost you". I'd have been perfectly happy with "If I'd have lost you", so long as I didn't think too hard about what was being elided. I'd usually elide "have" there to just a schwa (neutral vowel) anyway, and think no more about it. How to use find command with wildcard when current directory contains a match? Possible Duplicate:          I'm having some confusion with the find command.

While it comes with some interesting changes, the Desktop icon system was messed up in my opinion. When you hover the mouse cursor over the icons, you see a huge space marked around them that cannot be violated (as you can see in the image below) so that they need to be placed very far apart from each other.  18.04 allowed you to place icons much closer to each other and didn't have that marked space around them. This new way leaves much less space on the Desktop to organize large amounts of icons - including folders, files and shortcuts. Is there a way I can significantly reduce the size of icons and their "spaces" or go back to the old system of organizing files? On "Settings", there is a tool to change the size of Dock icons, but not of Desktop icons.  Also, every time I move or delete something, the Desktop "flashes" and the icons seem to rearrange themselves automatically, nothing of which happened in 18.04. I also can't move anything directly to the Desktop; I need to move to the Desktop folder on Nautilus. This makes me start to think about downgrading Ubuntu back to 18.04.
