Install Samsung ML-1675 drivers on Mac OS Sierra

Samsung apparently stopped the development of drivers on the version Mac OS X 10.6, so if you upgraded to Sierra and you still need to install your printer, follow the steps

1. Download drivers from Apple Support: https://support.apple.com/kb/dl905
2. On the installation this one appears as (Samsung ML-1670 Series), add the printer
3. Use the drivers for Samsung ML-1860 Series

This solution worked because CUPS generated the error:

INTERNAL ERROR – Please use proper driver.

POSITION: 0x0

SYSTEM: h6fw_5.49/xl_op

LINE: 180

VERSION: SPL 5.49 10-20-2010

And looks like the 1600 series is the 1860 in the USA.

 

Uninstall MySQL Server on Mac OS

When I upgraded from Mac OS X 10.12 (Sierra) to 10.13 (High Sierra) suddenly my MySQL Server just broke down and it was unrepairable, so I’m going to try to install it with brew, but in order to do that I needed to uninstall the current one and this is a clean way to do it

Just run the following commands

sudo rm -rf /usr/local/mysql
sudo rm -rf /usr/local/mysql*
sudo rm -rf /Library/StartupItems/MySQLCOM
sudo rm -rf /Library/PreferencePanes/My*
rm -rf ~/Library/PreferencePanes/My*
sudo rm -rf /Library/Receipts/mysql*
sudo rm -rf /Library/Receipts/MySQL*
sudo rm -rf /private/var/db/receipts/*mysql*
sudo rm /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist

I had a problem with a configuration file, so it’s better to remove it

sudo rm /etc/my.cnf

This is a really big time saver and helper when you don’t remember which is the name of the parameter that you need, so in order to enable it you just need to do the following.

How to fix “mysql command not found” on Mac OS

Contrary to what I think this utility it is already on your computer the only thing that you need to do is inform to the bash where is it, so in order to do that add “/usr/local/mysql/bin” to the path on your ~/.profile file and thats all.

export PATH=/usr/local/mysql/bin:$PATH

Use shared folder to develop with a VirtualBox Ubuntu Server guest

Recently the company that I work for change my Lenovo T440 with Ubuntu 16.04 for a MacBook Air with macOS and although I never really liked Mac (Too expensive for the specs provided) I loved the change but there are several differences that, when it comes to web development, I need to take in account, so I just installed a local Ubuntu 16.04 server with VirtualBox to test my work before to put it out.

To avoid having to pull the source code each time I just wanted to share the development folder with the guest machine and in order to do that we need to make the following steps

Install the VirtualBox Guest Additions in the guest
