My Pi is doing a pretty good job on connecting to wifi when I travel between places. Unfortunately, my autossh job on the Pi is not working.
I set up autossh to open up a reverse ssh tunnel to a known host, allowing me to always ssh to my Pi ...

When you're playing around with the Raspberry Pi, there are multiple times when you won't have a screen attached to the Pi but you'll want the IP address to use with SSH. What I did was set up static IP addresses on my DHCP server (in this ...

I have a bad habit, and that's of buying domain names. I have about 20, with several different registrars. If I was smart, I would consolidate them under one registrar, but, even then, checking expirations on the domains is a pain. I usually have autorenew turned on, but I ...

I've had a Raspberry Pi 2 just sitting around for several months, waiting for a purpose. Since I haven't come up with a purpose, I decided to make it a portable headless Linux box that will travel with me, connect to Wifi automatically, and eventually, hopefully, set it ...

I've been experimenting with Taskpaper for lists over the last couple of weeks, and really like the flexibility. All of my lists are stored as text files in Dropbox, which makes it easy to use/update lists from anything or anywhere. On my iPhone I use Drafts to quickly ...

This past week I worked on a bash script to create some input files from a MySQL database. My problem was trying to use multiple line MySQL statements, which was messing everything up. The solution was to use bash's Here Documents. It's a way to direct lines into ...

I have a couple daily taskpaper lists that by the end of the have an @done on each line and I need to reset it for the next day. Instead of trying to do a search and replace everyday, I added a bash alias to .bash_profile (or .bashrc):

The history from the commands typed into bash are very useful from time to time, especially when I think "Oh, I'll remember that command next time I need it", and then I don't. The problem with bash's history are twofold:
- It only saves history when the terminal ...
