The Talking Mirrors: Another Look at Heliography Communication:

E-mail Print PDF
Before there were "ones and zeros" used by digital communication and the Internet, technicians keyed Morse code over copper wire to talk from place to place almost instantly. But even before electricity and electronics made communication faster, there was light. And the military, which often finds technology first, discovered that the use of glass and mirrors to communicate would speed communications over the heads of their enemies far faster and more reliably than a horseman could. Heliography uses mirrors to reflect sunlight over great distances for the purpose of sending information. The invention of the heliograph is dated 1865. The heliograph still has many followers, who have tested its use in demonstrations. For further reading on heliographs read James Riddle's Web site http://myweb.cableone.net/Kd7aoi/

Ham Radio Group Prepares for Emergency Call:

E-mail Print PDF
When an ice storm struck the region in late January, tree limbs fell, utility poles broke, and in the process, electric and telephone lines snapped, leaving thousands without power or communications. Additionally, cellular telephone service was down because of the weather conditions, leaving communication availability with the "outside world" almost impossible for the first 24 to 48 hours after the storm was over. As a result of the ice storm, a group of Webster County residents who want to make sure that communication outage never happens again, are organizing a Webster County Amateur Ham Radio Club for interested citizens. Bill Wyant, Hugh Smith, and Jeff McBride, while sitting at Wyant's home in Dixon, said they plan to hold the first organizational meeting for the new club on Monday, April 21, at 7 p.m. at the Webster County Senior Citizen's Center in Dixon. "We want to work with the county in case of an emergency so we can have communications," Smith said.

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.
