How to disable MySQL server from constantly running in the background?

This website explains MySQL server installation in Ubuntu 18.04. Basically you issue the command sudo apt install mysql-server. The same website then explains that:

Once the installation is completed, the MySQL service will start automatically. To check whether the MySQL server is running, type: sudo systemctl status mysql

Does this imply that once I install mysql-server it will always be running in the background unless I explicitly kill the process upon each reboot?

I want to play around with mysql-server occasionally, but don’t want it constantly running in the background.

Disable Automatic Workspace Switching on Ubuntu 18.04/Gnome 3

I recently switched from mac to ubuntu for my laptop OS and was disappointed to discover one of my favorite mac configuration options, being able to disable automatic workspace switching, doesn’t appear to be available on ubuntu.

I would like to disable automatic workspace switching so that when I hit the super key and enter the name of an application that already has a window open in another workspace (firefox or files, for example) the active workspace does not switch to the one in which the application is already open. I have seen several previous questions and am aware of the “just middle or right click the app icon” solution, but I would like to be able to open applications by just hitting the super key and entering them without having to use my mouse.

Have any solutions been developed for this issue since the last time it someone asked about it in 2016?

SharePoint 2010 – disable SSLv3 and TLS 1.0

I’m tasked to figure out how to disable SSLv3 and TLS 1.0 on SharePoint 2010 farm.

After some reading, I came to the following conclusions:

  • It is safe to disable SSLv3 on SharePoint servers,
  • It is not possible to disable TLS 1.0, because communicatin between SharePoint servers would fail as other TLS version are not supported.

So it looks like we can’t disable TLS 1.0 due to possible failure of communication between servers. I’m however thinking about scenario where we:

  • don’t disable TLS 1.0
  • we enable TLS 1.1 and 1.2
  • we configure IIS SharePoint sites to require TLS 1.1 or 1.2 on the endpoints that are publicly available

My thinking is that if we could enforce TLS 1.1 and 1.2 on the public-facing endpoints, servers between themselves could still communicate with TLS 1.0, and client could connect only with higher TLS versions.

Please let me know if what I came up with makes sense, and point me in the right direction how to configure it. In case it’s not possible, please let me know what other options I have.

Disable OPEN in SharePoint Online options?

My company has a SP list for a staff directory called Who’s Who. All of the columns are visible in the All Items view except for 1 field — the Mobile Phone number. That is only visible to the HR (and IT Development) staff using a view called HR-View. I have confirmed that a general user cannot access the HR-View and that the column is not shown in Quick Edit mode.

There is 1 problem. A general user can select a person, then click on the ellipsis and choose Open. The fly-out opens and exposes the Mobile Phone number to the general users (a big no-no). Do I have to create a new fly-out for the view/edit forms, or is there a way to disable the Open menu option.

***enter image description here***

FYI – the general user cannot edit the data in the fly-out because they are read-only, but that can read a column which we would prefer they not be able to see.

How to disable iMac infrared remote control?

I have successfully disabled my infrared remote on my iMac. Are these changes going to be overwritten with a future software update?

I have a fresh install of Ubuntu 19.04 on a stock Apple iMac 9,1 (24 inch, early 2009). Out of the box the computer responds to input from the Apple Remote. However, I have an Apple TV box in the same room so I want to disable the Apple Remote from the iMac.

Here’s how I solved the problem:

Add the following to /usr/share/X11/xorg.conf.d/10-quirks.conf to have Xorg ignore the infrared receiver:

Section "InputClass"         Identifier "Apple IR Receiver, disable"         MatchProduct "Apple Computer, Inc. IR Receiver"     Option "Ignore" "on" EndSection 

However, the login screen was still accepting input from the Apple Remote. After some digging, I determined that the login screen runs a program called gdm3 which by default launches Wayland for the display instead of Xorg. It is unclear to me how to configure Wayland in a similar way to Xorg to ignore the Apple Remote, so configure gdm3 to use Xorg:

Un-comment the following line of /etc/gdm3/custom.conf:


Now my iMac no longer responds to Apple Remote key presses both before and after login.

Xorg treats the Apple Remote as a keyboard, and it is possible to disable this keyboard using the xinput disable command, but that is only good for the currently logged in user and reverts after rebooting.

How to disable “Connect to Teams” banner in SharePoint Online

We have a set of Group connected Team sites in SharePoint Online and we don’t want to connect them to Microsoft Teams due to some specific business need. The problem is that whenever an Owner of the site or site collection administrator login to one of those sites, SharePoint displays a banner on bottom left of the screen, asking the user to “Connect to Teams”. Although the user can close the banner but the user can also click the link by mistake and the site will be converted to MS Team. Since it is a one-way process therefore, I want to make sure the user should not see the banner at all. I have tried PnP and normal SharePoint Online PowerShell, UI, REST API but I am unable to find any way to disable this banner. Can somebody guide me if there is a way to disable/hide this banner? I have checked Microsoft site and it is a feature introduced last year
