Move or relocate /var to another partition in CentOS 6.8

A few steps to easily move or relocate /var in CentOS 6.8:

Start by sudo bash.

- Mount the future /var with a different name, like /newvar.
  Tip: Setup fstab to use /newvar and use "mount -a" will also help you checking if fstab is fine.
- Copy current /var to new location with rsync:
       rsync -aqxP /var/* /newvar
- fix the security contents with
       restorecon -r -v /newvar
- adapt fstab to mount the new /var (if you had setup fstab to /newvar now is the time to set it to /var)
- reboot

Use [by default] TLS 1.2 on PowerShell

As simple as this:

TP-Link MR3420 and Vodafone Modem K5160

TP-Link MR3420 v2 refused to work with my new K5160.

The firmware from TP-Link didn't help so I give a try on "Of Modems and Men" firmware [ROOter].
It's quite simple to install the firmware (but be aware that rollback is not so simple).

ROOter firmware identified the modem correctly but still no connection to the internet. It seems that the hostless modem is still working as MBIM.

The trick is to ssh to the modem, rename /sbin/umbim to something else and reboot the router. 

Get size of each table on MS SQL Server database

Simple query to get the size of each table on Microsoft SQL Server database.

SELECT TOP 1000 t.NAME AS TableName, s.Name AS SchemaName, p.rows AS RowCounts, SUM(a.total_pages) * 8 AS TotalSpaceKB, CAST(ROUND(((SUM(a.total_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS TotalSpaceMB, SUM(a.used_pages) * 8 AS UsedSpaceKB, CAST(ROUND(((SUM(a.used_pages) * 8) / 1024.00), 2) AS NUMERIC(36, 2)) AS UsedSpaceMB, (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB, CAST(ROUND(((SUM(a.total_pages) - SUM(a.used_pages)) * 8) / 1024.00, 2) AS NUMERIC(36, 2)) AS UnusedSpaceMB FROM sys.tables t INNER JOIN sys.indexes i ON t.OBJECT_ID = i.object_id INNER JOIN sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id INNER JOIN sys.allocation_units a ON p.partition_id = a.container_id LEFT OUTER JOIN sys.schemas s ON t.schema_id = s.schema_id WHERE t.NAME NOT LIKE 'dt%' AND t.is_ms_shipped = 0 AND i.OBJECT_ID > 255 GROUP BY t.Name, s.Name, p.Rows ORDER BY t.Name

What if you lost the password of an old SMC 8612T Tiger ?

The manual says that you should connect via console and use Ctrl U when it starts but this procedure will lead you to a password prompt. The password that you don't know.

Instead, use Ctrl F. As simple as that. SMC, please fix your manuals.
