There's an issue with the Shorewall package in Debian 9 Stretch, causing Shorewall not to automatically start even when the required configuration files are in-place and/or modified. As stated here, the problem also exists on Ubuntu with some versions of the package (see article).

The problem lies with the package not enabling the startup script in systemd during installation. The solution is to manually enable this by running the following command (as sudo):

systemctl enable shorewall.service

This will enable Shorewall to automatically start during a reboot. Note that you will still have to set the correct parameters in /etc/default/shorewall (and possibly /etc/shorewall/shorewall.conf t  ...

You can easily run Transact-SQL (T-SQL) script files (with extension .sql) via the commandline utility sqlcmd:

sqlcmd -S Server\Instance -i C:\path\to\SomeScript.sql

By default, the output is written to the command prompt. You can also save the output to a file:

sqlcmd -S Server\Instance -i C:\path\to\SomeScript.sql -o C:\path\to\TheOutput.txt

Note that when using this, no output is written in the command prompt window.

You can quickly reset a Samsung A3 smartphone by booting into recovery mode (e.g. when you're locked out):

Turn off the phone by holding down the power button (right side) and then select to power off.

Hold down Volume up, Home and Power buttons to power the device on. Keep Volume up and Home down until you see the Samsung logo. After a while you will get the recovery menu.

Use the volume buttons to navigate in the menu (up for up, down for down). Select wipe data/factory reset, then press the Power button to confirm. Use the same keys to select yes if an additional prompt appears.

The reset takes a very short time after which the recovery menu will be displayed again. Either select rebo  ...

Safari has an option to automatically open files that are considered "safe". Usually these are document types (e.g. PDF) but sometimes it may become necessary to add other file extensions that are not considered "safe" by default. This can be achieved easily by adding/editing a plist configuration file to your profile (i.e. user-based setting).

The preferences file is located at ~/Library/Preferences/com.apple.DownloadAssessment.plist, and determines whether a specific file extension is considered safe or not.

If the file does not yet exist, create it with the contents below:

<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.ap  ...

When attempting to connect to a SQL Server 2014 or SQL Server 2016 using SQL Server Management Studio 2012, you may encounter the following error:

Microsoft SQL Server Management Studio
An exception occured while executing a Transact-SQL statement or batch. (Microsoft.SqlServer.ConnectionInfo)

Additional information: VIEW SERVER STATE permission was denied on object 'server', database 'master'. (Microsoft SQL Server, Error: 300)

Apparently, this is a known bug when using Management Studio 2012 to connect to a newer version of SQL Server: https://connect.microsoft.com/SQLServer/feedback/details/791630/cannot-view-properties-of-database-when-using-db-owner-account.

Resolving hostnames locally enables the use of hostnames (instead of IP addresses) without relying on a DNS server. If you do not want to use reverse DNS resolving but still would like to use hostnames instead of IP addresses, then this is a useful workaround. The key is to configure syslog-ng to use only the local DNS cache as a source for reverse DNS lookups, completely eliminating the need for a DNS server (and the negative impact this would entail).

Add the hostnames and IP addresses to the local name resolution file /etc/hosts, then reconfigure syslog-ng (by editing the global options in /etc/syslog-ng/syslog-ng.conf) to use DNS resolving but only use the persistent cache (i.e. whateve  ...
