23.4 Site Logs

The hosting service typically provides a log of everyone that visits your site and what pages they looked at.

This data can be analyzed to understand how customers use the site.

23.5 Email

An advantage of having your own domain name is that email is addressed to your domain not the ISP. This

personalizes your web presence. Normally the hosting service provides one or more e-mail accounts. Email

is structured as username@domain.TLD. The hosting service can sort incoming mail by user name if you

need multiple mail accounts. You can also run your own mail server to create multiple accounts.

Regardless of how many accounts you create one account is an alias. This is where mail not sorted to

another account is deposited. I did not realize how useful that is until I started creating a unique username

every time a site asks me to register. That way it is easy to determine who sold your email address when

you start getting SPAM.

24 Power Distribution – Wires and More Wires

Creating a home network tends to create a jumble of cabling,

both data and power to feed the computers and large number

of wall warts used by small devices. After struggling with

multiple power strips I decided to try an organize power

distribution.

Power Panel requirements

Multiple always on receptacles

Multiple switched receptacles

Wire routing provisions

Mounting provisions for larger power supplies.

I wanted a large number of always on outlets. Power bricks

tend to take up a lot of space, so the number of power strips

is generous, four strips with six receptacles each. To

minimize power consumption devices that do not have to be

on continuously are automatically switched on/off with the

workstation. An adapter cable plugs into the PS/2 keyboard

or mouse port to pickup 5 Volts. This controls a solid-state

relay that feeds the switched power strips. One note of

caution; some power managed PCs leave PS/2 ports on all

the time to allow remote power up. If that is the case the

power panel needs to sense power directly from the main

power supply.

Two rows of Velcro are used to organize the wiring. The

upper level consists of Cat5 Velcro cable wraps. This holds

surplus cable. The bottom row uses longer pieces of regular Velcro to hold inline power supplies.

The power panel has been used for several years and goes a long way to providing a safe environment and

reducing clutter.
