Software that I developed for reading the nda file format from Neware battery cyclers is now an open-source project on Github. It’s a tool that I developed as a side project at work that turned out to be a much better alternative than manually exporting to Excel and then read into Python. I’ve also included a command-line tool which can convert nda directly to a variety of other formats without having to write any code. I had the benefit of being able to test against a large number of nda files from different generation cyclers, which I hope has resulted in robust code.

Unison and Godaddy Linux Hosting
For a while I have been struggling to find a way to use unison to sync local files with Godaddy web hosting storage space. Although the Godaddy server runs Linux, it does not have unison installed. I found several suggestions to use sshfs to mount the Godaddy home directory locally, and then use unison to sync the mounted folder. This approach is very slow because it requires a lot of extra data transfer, and, as others have also found, large sshfs transfers to Godaddy seems to freeze after a short period of time.
However, there is a much better solution. It’s possible to install a local copy of unison in your Godaddy home directory and then use unison normally. Here’s how. First, I determined the operating system on my Godaddy server:
cat /etc/redhat-release
My account is hosted on a server running CentOS 5.5. So next I downloaded the appropriate unison rpm (i386) from http://pkgs.repoforge.org/unison/, and unpacked the contents of the rpm with this command:
rpm2cpio myrpmfile.rpm | cpio -idmv
If you do not choose the correct rpm to match your local unison version you may encounter version incompatibility errors, and if you choose the wrong rpm for the Godaddy operating system you may get errors about glibc.
Then place a link to unison executable in your bin folder so you will have unison in your PATH. At this point I could execute unison on the Godaddy server, but if I tried to sync from my local computer I would get an error that the unison command could not be found. The problem is that unison was only in the PATH for ssh connections that opened a shell, but unison passes its commands via the ssh command line. I couldn’t find a way to resolve this problem on the Godaddy side, but there is a workaround. By adding the following line to my unison .prf files, it’s possible to tell the Godaddy server where to find unison:
servercmd = /home/content/d/a/c/dac437/bin/unison
At this point, I was able to successfully sync 7GB of digital pictures to my Godaddy home directory using unison.
Panasonic Vierra TH-42PZ85U Overscan
I’m positing this with the hope that helps someone else avoid frustration. For several months I had overscan issues displaying HDMI from my computer on my Panasonic Vierrra TH-42PZ85U. The TV always cut off the borders of the screen. I searched forever for overscan options for the TV, and even tried to write custom modelines without any success. Many posts in forums were reporting similar frustration. However I finally found a simple solution. On the TV, go to Menu->Picture->Advanced Picture->HD Size. Changing HD Size to 2 fixed the problem!
