Emergency Radio Tower Rises Over Obstacles:

E-mail Print PDF
ADRIAN, Mich. -- The end of a three-year struggle with state and federal agencies was punctuated Wednesday by a 102-foot emergency radio tower. Curtis Parsons, Lenawee County's emergency management coordinator, was smiling as a crane set in place the tower that has been a headache for the Lenawee County Emergency Services Department since the fall of 2006. An antenna tower was proposed when the county's new emergency operations center was established. Officials are to gather in the center to direct responses to disasters. But a state agency objected that the tower would interfere with the view of the historic Lenawee County Courthouse across the street. Antennas for the Civil Air Patrol and a local amateur radio group were attached to the tower Wednesday and readied for immediate use. Connections to the county's fiber optic cable are to be completed in the spring, Parsons said, finally giving radio equipment at the emergency operations center its own antenna.

Propagation Forecast Bulletin #7 de K7RA:

E-mail Print PDF
Sunspots returned this week, or one did, but it is an old Cycle 23 spot. Sunspot 1012 has been visible the last couple of days, February 11-12. It is down near the Sun's equator, which is typical for spots from a previous cycle. Nice to have a sunspot, but it doesn't indicate activity from the new Cycle 24, which has been so eerily quiet.

git – renaming branches

E-mail Print PDF

I was working on a project recently, which involved cloning another git repository and adding my own changes into it. After I cloned it, I forgot to create and switch to the new branch and do my changes there. So all my changes were in the ‘master’ branch. I rather wanted to have my changes in my own branch. git makes these things trivial. All you have to do is rename your current master:

$ git branch -m <old-branch-name> <new-branch-name>
$ git branch (should show the new name)

Now, do a git log and find out which is the commit before you started making the change and do:

$ git checkout -b <old-branch-name> <commit-sha1>

That’s it and you have the whole thing as you wanted it to be.

Thanks to my friend Anand for the tip on the -m option to git branch. Most git gems seem to be deep embedded in those switches of the sub commands of git.
