After replacing the TDS router with a Tomato powered device TV shows were no longer getting recorded properly on the TDS DVR. The behavior I was seeing was that recorded programs had no video (black screen) and played at an accelerated rate.
I wanted to add a second router to my home network such that:
- Devices that connect to it get put on the main LAN network
- No double NAT
- A single DHCP server doling out IP addresses
- The administration panels of all routers are accessible
When you log into an Ubuntu box on the command line, the first thing you see is the “message of the day” (motd). It may have something like this in it:
*** /dev/sda1 will be checked for errors at next reboot ***
which doesn’t go away even after rebooting. Here is how to solve that problem.
Ubuntu has started to support USB audio. When I plug in a USB speaker or headset, it gets recognized and installed automatically. However there are some bugs:
- The USB sound device does not get selected automatically. This is especially annoying for headphones. When you plug in analog headphones, the sound automatically switches to them and the main speakers turn off.
- The volume settings are turned way up for the device. Ideally it would remember the volume settings from the last time the device was plugged in.
- When the computer goes to sleep, the volume of usb devices gets turned way up on wake.
I discovered that I could address these shortcomings by creating a script.
I try to script everything I can on Linux. When I install something on my desktop, I like to be able to run a script to install the same thing on my laptop. When a computer breaks, I like to be able to run all the scripts to have it set up again just the way that it was. Here is how I scripted the installation of my printer.
The wireless network on my laptop has always been unreliable. When I open the lid of the laptop and the computer wakes up from sleep, there is a 10% chance that the wireless network won’t be able to connect. In the past, the only thing that works in this situation is a full reboot of the laptop.
