To make a .sql file just go to the cmd line and type mysqldump Database > .sql File name.

    cmd        Database          .sql file
mysqldump test            >    dump.sql


example :   mysqldump --opt -u root -p'YourPasswordHere' gallery3 > ~/gallery3.sql

If you have your old web.config, you need to take the line that says AsymmetricKey and move it over to replace the one in the new web.config. You can't recover the full key if you don't have the web.config.

              Source Server     The Path        Destination Folder on the server
mount       192.168.1.250:/mnt/bigdisk /mnt/bigdrive

Problem:   If the message mount.nfs: access denied by server while mounting

Solution:  1st      showmount -e "the ip of the computer share"   check to see if the /mnt/drive is being shared.
                2nd     check that the usr is mapped and the correct group set
                3rd      if using a server mak sure the nfs server is running and the correct mount is being served.

You can change the resolution via SSH using the following commands (login as 'chip' user, not as 'root'):

chip@chip:~$ export DISPLAY=:0
chip@chip:~$ xrandr --output HDMI-1 --mode 1280x720 --rate 60.00

SCENARIO 3: UPGRADING A NEW PC FROM HOME TO PRO

Let's say you buy a new PC with Windows 10 Home installed by the OEM. When you check the Activation page in Settings, it should look something like this:


If you have a Windows 10 Pro product key, you can click the Change Product Key button and enter it here. Easy.

If you don't have a Pro product key and you want to buy one, you can click Go To Store and purchase the upgrade for $100. Also easy.

But what if you have a Windows 7 Professional or Ultimate key, or a Windows 8/8.1 Pro key? In that case, you need to do the upgrade in two steps.

First, make sure you've installed the November update and you are running version 1511.

Next, click Change Product Key and enter the default Windows 10 Pro key (see above). After the upgrade completes, check the Activation screen again and you'll see this:


What, you were expecting that default key to magically give you a $100 upgrade? Sorry, that's not how it works, despite what you might have read elsewhere.

Instead, click the Change Product Key button and enter your Windows 7 Pro/Ultimate or Windows 8/8.1 Pro key. Assuming it's a legitimate key and you are running Windows 10 version 1511 or later, your activation should complete successfully.

If that process seems cumbersome, you're right. It does go fairly quickly, however.

I found an answer through some easy googling that seems to have worked...there are three folders in the AVG folder in Program Files that you need to delete, but you have to disable avg first...

1. Disable AVG self protection:
Right click the AVG icon in the taskbar (near the clock)
Select to Temporarily Disable AVG Protection
Agree the default timeout - usually 10 minutes?​
2. Open My Computer or Windows Explorer and Navigate to:
C:\Program Files\AVG\AVG201x\ ...... for 32bit systems (201x means 2013 or 2014)
C:\Program Files (x86)\AVG\AVG201x\ for 64bit systems​
3. Delete the following three folders: Awacs, Banners, Tuneup
Do not delete anything else you see inside the AVG201x folder.
If you accidentally delete anything else go to the recycle bin and restore it.
Note: If you have already paid for the Tuneup addon then keep this folder​
4. Close the My Computer/Explorer window
5. Enable AVG self protection:
Right click the AVG icon in the taskbar (near the clock)
Select to Enable AVG Protection - takes 20 seconds or so to fully activate.​
