Change favicon in SharePoint 2013

This is a quick fix!
To change the icon that is displayed on the bookmark in a browser from the:

To something more sexy, then do the following:

Create a new folder in this location C:Program FilesCommon Filesmicrosoft sharedWeb Server Extensions15TEMPLATEIMAGES
I named mine “Custom”. This is always best practice, so that your changes wont be overwritten in any update.
Paste your new favicon file, dont forget to rename the file extension to .ico

Open your html version of the master page (if you have a custom)
Change the location inside the tag 

The Current server is running low on memory

There is an error reported in Health Analyzer on my SharePoint 2013 server regarding the Distributed Cache “current server is running low on memory”.
 
So, the Distributed cache uses 10% of the  total physical memory on the server. The Distributed Cache service uses half of that memory allocation for data storage (also known as cache size), and the other half of that memory allocation is used for memory management overhead. When the cached data grows, the Distributed Cache service uses the entire 10 percent of the allocated memory.  (Source: technet)
To check the existing memory allocation, run this command
Use-CacheCluster
Get-AFCacheHostConfiguration -ComputerName ComputerName -CachePort “22233”
 
There is 16 GB RAM on this server, so 819 MB is not enough. First stop the Distributed Cache Service in Services on server in CA
I first tried to update the size to what Technet recommended (7168 MB) but then I could not start the service again since I did not have enough free memory:
 
Instead, I updated the size to the double at 1600MB with this powershell cmd:
Update-SPDistributedCacheSize -CacheSizeInMB 1600
Then started the Distributed Cache service and the message in Health Analyzer disappeared.
 

Tasks and Timeline disabled with bootstrap in IE11

This problem ONLY concerns IE11 and on a SharePoint site using the bootstrap theme. When you create a Team Site and add a Task list, the ribbon is disabled and either the Tasks nor the Timeline is visible. If you open the same site in IE10 or Chrome, it is visible and working.
The site is added into the Compatibility View Settings and if I apply the Default Theme then it all works so it must be something in the bootstrap CSS files or JS that is blocking.
 

Hide Conversations from Search

If you want to hide the “Conversations” options from the dropdown menu that is shown after the Search box, the easiest way is to CSS hide it. Set the following class to “display:none”.
#ctl00_PlaceHolderSearchArea_SmallSearchInputBox1_csr_NavDropdownList div:nth-child(3){display:none;}
 
Then you want to remove the same option from the Search center page (results.aspx) also.
Edit the Search page (in the Search center)
Edit the Search Navigation web part
Click on “Search Settings Page”
Select “Conversations” and “Delete”
Done.
