Ham Radio Operators Learn to Turn Hobby into Vital Link:

E-mail Print PDF
Operating a ham radio can be a lot of fun, but in times of emergency it also can be a lifesaver. Members of the Cape May County Amateur Radio Club know this full well and have lent their hand in more than one emergency situation. The nonprofit organization began in the 1970s in Stone Harbor but in the '80s grew to encompass all of Cape May County. The purpose of the club is to provide a public service to shore communities through the development of supplemental emergency communications facilities. Members are licensed by the federal government and first have to pass a test. But then, with just some basic equipment, ham operators can enjoy their hobby, being able to speak with other ham radio operators around the world. Roy Conners, of Cape May Court House, is a member of the Cape May County Amateur Radio Club and serves as its public information officer. He has been involved with amateur radio since he was a boy. "I started fooling with ham radios when I was about 12 and television was just starting in the 1940s," Conners said. "I am a tinkerer, always building things, and I would find parts in the trash that I would put together to make radios. It never lost its fascination for me. Just being able to put up an antenna and receive a signal is a thrill for me. Ham radio operators can speak with others around the world and even to space stations and satellites. It's just a fascinating hobby to me." Conners said in times of weather or other emergency, ham radio operators swing into action. When other lines of communication are down, ham radio operators can become a vital link," Conners said. "We help in all types of emergencies like hurricanes and other storms. During the World Trade Center attacks, thousands of ham radio operators converged on the scene ready to lend a hand."

Lisp, again

E-mail Print PDF

Since Neuros OSD2 hacking has been abandoned and also because my ham radio interests are currently in hibernation and also since my family is away for a while, I decided to take up some self learning. I have decided to re-start my lisp studies. The goal is to reach a stage where I can write non-trivial programs with lisp. To achieve this purpose, I have choosen the following path:

  • Grok Practical Common Lisp, arguably the best introductory Lisp book available today. Unfortunately there are no exercises, but there a few quite good “Practicals”.
  • Watch the SICP lecture videos. I don’t like watching them on my PC as my attention span has reduced considerably, thanks to Internet. I use the versions available for viewing on IPod and watch them on my (loaned) Apple IPod. It had been quite effective. The 320×240 resolution is more than enough. I don’t have to sit in front of my computer, instead I sit with a pen and notebook, just like in a classroom.I can also listen to them while travelling in trains. These days, I am a regular on weekend trains between cochin and bangalore.
  • Read SICP and work out the exercise. I have a dead-tree version of SICP for some years now. Every time, I read parts of the book but never completed even half of it.

I am making good progress with Practical Common Lisp. Though there is an online version, I decided to buy a dead-tree version. I am finding that Common Lisp is one of the best language for a C programmer like me to learn, instead of Scheme. Scheme syntax and CL syntax has got some subtle differences.

It would take me many months to continue this process. But I have decided not to get distracted with other things during this study. I also have afew projects in mind which I can use Common Lisp for. I am not sure, whether I can go anywhere near the effort that this guy undertook. But even if it is a bit of what he did, it is going to be very beneficial.

Also, if anyone would like to take this undertaking and would like to form a study group (in Bangalore), let me know, we can chart out a plan to meetup regularly and spend time on the lisp study.

Strange New Air Force Facility Energizes Ionosphere:

E-mail Print PDF
Todd Pedersen had to hustle:the sky was scheduled to start glowing soon, and he didn't want to miss it. It was just before sunset, a cold February evening in deep-woods Alaska, and the broad-shouldered US Air Force physicist was scrambling across the snow in his orange down parka and fur-lined bomber hat. Grabbing cables and electronics, he rushed to assemble a jury-rigged telescope atop a crude wooden platform. The rig wasn't much, just a pair of high-sensitivity cameras packed into a dorm-room refrigerator and pointed at a curved mirror reflecting a panoramic view of the sky. Pedersen had hoped to monitor the camera feed from a relatively warm bunkhouse nearby. But powdery snow two feet deep made it difficult to string cables back to the building.
