Grey-haired geek, perennial polymath.

I used to develop in Java but I got tired of all the brackets and static typing, so I now play with Python.

In case people wonder about why I am also registered for the English and Chinese Stack Exchange forums, I recently spent a couple of years in China teaching English.

comment How can I “install” a driver for a USB-to-Serial adapter?
Worked for me. Adding to the /etc/modules file no longer seems to be necessary. Also, I found the .ko file extension should not be stated in the modprobe command.

+1 for this because it helped me with MacOS line endings.

comment Calibrate Touch screen permanently
@Justin I posted the entire code snippet (not just one line) in a separate file. No problems with Unity. But, yes, it probably runs faster not using 3-d graphics on the desktop...

comment How do I remove or hide old kernel versions to clean up the boot menu or free space?
I tried the approach using Ubuntu Tweak as being the most appropriate (i.e., idiot-proof). Worked well.

comment Printer scanner driver for Epson Workforce WF-5320
@zkurtz There are several ways to get the printer's ip address. In my case I like to set it in the router, so it will always be the same. Another way is to go to the printer and get it to print out it's wireless settings, and a third way is to check the ip when you use the Add Printer tool's Network Printer option; it searches the lan and reports the ip addresses of any printers it finds.

comment Printer scanner driver for Epson Workforce WF-5320
At the simplistic level this is correct, but to make use of scanner features you need the proprietary drivers. Similarly, when you add the printer with the Printers tool the correct software for the drivers is detected and downloaded, so it is not strictly correct that additional drivers are not needed.

comment How to fix “The system is running in low-graphics mode” error?
This may help when the problem is to do with the desktop, but usually for me this type of problem comes from a combination of the graphics drivers and a kernel upgrade. In this case the other answers here are more appropriate, with particular reference to @Luis.

Seeing this made a grey-haired geek happy.
