Rich Hickey on becoming a better developer

Rich Hickey • 3 years ago

Sorry, I have to disagree with the entire premise here.

A wide variety of experiences might lead to well-roundedness, but not to greatness, nor even goodness. By constantly switching from one thing to another you are always reaching above your comfort zone, yes, but doing so by resetting your skill and knowledge level to zero.

Resize root partition (or how to remove the default /home partition) on CentOS 7 online

This requires you to be able to ssh into the instance using the root user account and that no services be running as users out of /home on the target machine.

The examples are from a default installation with no customation-you NEED to know what you're working with for volumes/partitions to not horribly break things.

By default, CentOS 7 uses XFS for the file system and Logical Volume Manager (LVM), creating 3 partitions: /,/home and

Step 1 - Copy /home Contents

Configure rsyslogd on CentOS 7 as Remote Syslog Server

echo "\$ModLoad imudp" > /etc/rsyslog.d/server.conf
echo "\$UDPServerRun 514" >> /etc/rsyslog.d/server.conf
echo "\$ModLoad imtcp" >> /etc/rsyslog.d/server.conf
echo "\$InputTCPServerRun 514" >> /etc/rsyslog.d/server.conf
echo "\$PreserveFQDN on" >> /etc/rsyslog.d/server.conf

yum -y install rsyslog-gnutls rsyslog-mysql rsyslog-crypto
