Canonical has just announced that the Ubuntu Developer Summit will no longer be face to face and every six months. Instead it will be entirely online and virtual, using Google Hangouts. (Here is the announcement.)

On the surface, this seems like a good idea: It's cheaper monetarily, it appears to open things up to people who are unable to travel, and it makes it easier to make complete records.

However, I think it's a bad idea, for several interrelated reasons.

Some decision making needs face-time to happen. For whatever reasons, internet-only communication is not enough for a good enough "meeting of the minds" for sticky or subtle engineering and design decisionmaking.

The IETF, who probably have the longest history of any organization ever of online internet-enabled …

MySQL accesses files in various places on the file system, and usually this isn't something to worry about. For example, in a standard MySQL 5.5 installation on Ubuntu, the data goes in /var/lib/mysql, and the socket is a file in /var/run/mysqld. It puts configuration files in /etc, logs and binaries in various locations, and it even needs to access some operating system files such as /etc/hosts.allow.

This is all very well until you start trying to be clever and get MySQL to access other parts of the file system. After all, you can configure the location of data, log files, socket, and so on, so why shouldn't you use those settings to optimize your system? Unfortunately, on many modern Linux distributions, it's not that always easy.

Take Ubuntu, for example. Ubuntu comes with something called AppArmor, a kernel-integrated application security system that controls how applications can access the file system. This goes above …

Ubuntu does not provide an apt-get repository package for MySQL 5.5 on this older OS, however this is still a widely used long term support version. The following steps will upgrade an existing MySQL 5.1 apt-get version to a standard MySQL 5.5 binary.

Step 1. Remove existing MySQL 5.1 retaining data and configuration

sudo su -
service mysql stop
cp -r /etc/mysql /etc/mysql.51
cp -r /var/lib/mysql /var/lib/mysql.51
which mysqld
dpkg -P mysql-server mysql-server-5.1 mysql-server-core-5.1
which mysqld
which mysql
dpkg -P mysql-client-5.1 mysql-client-core-5.1
which mysql
dpkg -P libdbd-mysql-perl libmysqlclient16 mysql-common
# This will not remove /etc/mysql if any other files are in the directory
dpkg -l | grep mysql
[ -d /etc/mysql ] && mv /etc/mysql /etc/mysql.uninstall
cp -r /etc/mysql.51 /etc/mysql

2. Prepare configuration and required directories.

sudo su -
MYCNF="/etc/mysql/my.cnf"
grep basedir ${MYCNF}
sed -ie …
