Pervasive Code

GNU Screen is a remote terminal multiplexer, described welll elsewhere.

I use it to eliminate the too-many-Terminal-windows problem on my laptop. I also use it to help me achieve some level of continuity on remote hosts, by leaving half-completed sysadmin tasks as-is until hours or days later even if I get interrupted or if the task is really long-running and I need to roam around with my laptop.

Today I decided to invest some time in making my command-line development environment launch with a single script. Here are the details.

Starting with Netscape 4.5, I’ve used Netscape, then Mozilla, then Thunderbird for email. I have a similar relationship with Firefox. I’ve watched with great hope and been disappointed over the years as Thunderbird bugs that really annoy me just… stay. I think I know why.

So, I wanted to try and attack Ruby in isolation.

You might be wondering, why am I working on backup scripting now? Don’t I have some big project I’m supposed to be working on 24/7? Yes, and actually this work is in the critical path of that project.

My super fast laptop is still away being repaired for a video problem, so I’ve taken a major hit in terms of the resources of my main computer: 90% less MHz, 36% less display area, 50% less memory. In the meantime, I’ve been avoiding tasks that need a lot of CPU or graphics performance and instead working on things that are easier on my old desktop computer.

This week, I decided that I would pause working on the design and implementation of my startup project, until I had really sorted out my server backup and monitoring situation.
