I opened the Summer issue of the Furman alumni magazine only to find a picture of my neighbor. (Unfortunately, the webmaster cannot keep up with the print publication and and there are many broken links besides). I would post links to the pics but cannot. Please make do with this scan.

I got the notion to learn something about GTK and review my C++. I have recently upgraded to Ubuntu 9.10 so some of the things I had before are gone.
Before you start, you will need libgtkmm-2.4-dev (version 1:2.18.2-1) installed.
When you install it should also call for
libcairomm-1.0-dev (version 1.8.0-1build1) will be installed
libglibmm-2.4-dev (version 2.22.1-2) will be installed
libpangomm-1.4-dev (version 2.26.0-0ubuntu2) will be installed
libsigc++-2.0-dev (version 2.0.18-2) will be installed
You may wish to install
gtkmm-documentation (version 2.17.4-0ubuntu1) will be installed
libglademm-2.4-doc (version 2.6.7-2) will be installed
libglibmm-2.4-doc (version 2.22.1-2) will be installed
libgtkmm-2.4-doc (version 1:2.18.2-1) will be installed
At that point, you can copy and paste the example code found on Wikipedia.
In order to follow the example literally, you will need to save each of the text files as the name indicated in the first line comment into an empty directory. Start a command line window and switch to that directory. Then the command given in the example should work.
If you copy and paste the g++ command you will get it right. If you type it, the “`” things are in the upper-left on most keyboards under the tilde (~), not a single-quote (’)

Hello world

There was a camp. All boys at camp Y-Noah in those days. Maybe different now. Back then a big treat was to go to a pine grove on the south side of the lake for an overnight. Great camping, quiet. And pine duff is soft and smooth. In those days, we carefully stepped across the spillway of the dam to get to the grove.
I am sure that many things have changed since those days. But one thing I know for sure is the same. The concrete dam that forms Lake Noah is still there. Which means that Headless Haddie still does not sleep at night.
That was already an old legend 50 years ago when I was a camper at Camp Y-Noah. Haddie was said t0 be a local girl, just about 12 or so. When the workmen were building the dam, somehow, Haddie, too close to where the concrete was being poured, was struck by a bulldozer, her head severed instantly by the impact, rolled into the flowing concrete and was buried. Her folks buried her body in a nearby graveyard. But on moonless nights, her ghost comes to the lake to see if she can find her head.
The sound you hear in the pine grove is Haddie’s dress, blowing gently in the summer wind.
Make sure you know where your stuff is. Especially your flashlight. Did you remember fresh batteries?
Sleep tight campers.
Sitting here on the deck on a seasonally hot day reading The Lost Symbol by Dan Brown. I have a glass of what was ice water. Before the ice “cubes” melted, they were prisms of a segment. That is the shape that the level water in the ice maker has as the intersection with the arc that is the mold. Someplace around here, I have articles (a,b,c) about ice maker repair but when it works an ice maker is a wonderful thing.
In a previous time, the ice cubes had to be made in the freezer section of the refrigerator. A metal pan held held metal dividers that had to be warmed or shifted with a lever to separate the rectangular prisms from the separators in the tray. When plastic became popular, a plastic tray made “cubes” with trapezoidal faces. These trays ejected the ice everywhere but into the glass you were trying to fill.
Back even farther, chunks of ice were broken from the same block of ice that cooled the food in the ice box. An ice pick was poked at the ice until a chunk came off. The block of ice likely came from an ice plant where ammonia refrigerant cooled a couple of gallons of water in each mold to make thousands of blocks every day.
Even farther back and maybe still today where it is more economical than not, ice was sawn from surface of a lake or even a purpose-built pond. Hauled and stored in an ice-house with sawdust packed between the blocks to keep them from sticking and to insulate.
Just some thoughts on a day when the temperature is 97 or so. A bit of a breeze make it tolerable. And ice water makes it enjoyable.
A tweet about a WSJ article authored by Penn Jillette that I read Saturday. The article led to an out-loud laugh when I read what it would take for Hummer to meet the fuel economy standard President Obama proposes. Mr. Jillette – this one’s for you.
While shelling a peanut, I had a flashback to a previous time in my grandparent’s yard. Grandma lived to be 102. Grandpa did not live as long. But my memory is of an earlier time in the yard in Clearwater, Florida. There was a chest-high chain link fence around the entire yard. But you could not see the fence except at the gates for the ivy that covered the fence. The fence was there for Granddaddy’s chickens. He had Plymouth Rock, Rhode Island Red, and Banties that I remember, and from what my mother said, the Banties, bantam hens and a fancy bantam rooster, were his favorites.
Granddaddy had peanuts in a brown paper sack. A rotating sprinkler watered the lawn, spinning in the morning, Florida sun, making the coarse, Florida grass sparkle. A crate that had once been used to ship an upright piano had been made into a playhouse by cutting a kid-size door in one end and a North-facing window in one wall. The crate had been there for long before I got there. The wood was the color of driftwood from weather. Setting it on cement blocks had protected it from termites and and tar-paper roofing and siding kept it from wet.
Perhaps if the packers of today’s wide-screen T.V.’s and such would print play suggestions on the sides of the boxes then kids could take advantage of the play value of the packing material before it went to recycling or landfill…
Objection! Liability. Granted. Strike that testimony.
I have just returned from Asheville, NC where I saw a most amazing play. PLUTO V. ERIS. A play to celebrate the 400th Anniversary of the publication of Galileo’s The Starry Messenger.
Full disclosure, I probably would not have heard about this play if my daughter did not play a part.
A classic play in the sense that it’s form and presentation model a Greek classic play. Or perhaps a modern civil trial.
A number of gods and goddesses from myth and legend are gathered for a Council of Celestial Beings. Eris, goddess of Discord, is accused by Pluto, god of the Underworld, of treason and general mayhem. Testimony proceeds through dialog and deposition. The costumes of the gods and goddess are outstanding from the Polynesian and Hawaiian god and goddess that open the show to the giant planet giants that join in the testimony. The cut paper figures in the shadow puppet deposition video are worth the visit in themselves. Classic shapes. Classic themes. Great action.
As the play unfolds, the interaction of myth and earth reality are explored. In the end, there are choices to be made.
The Vance Elementary School in Asheville Planetorium is the near-perfect performance space for this play. The semi-circular stadium is reminiscent of the Greek and Roman theaters of ancient times. More so because the ceiling of the Planetorium is hung with models of the planets with Earth the size of a basketball and the others to match.
Just one more performance in this round on the March 27, 2010 at 8:00 PM. A great show and worth the trip. A website for more info. Contributions benefit the Vance Elementary NASA program.
I do not claim any understanding of Nelder-Mead or anything like it, also called a downhill method of finding a minimum for a system of equations, which, if you keep up with these things, may be old news. But consider the possibility of the inverse, nearing the summit realizing that whatever your strategy and method, the climb has led you up the wrong peak. Or more to the point, in the valley, you cannot realize or see that the adjacent (or some very distant) valley is lower but not chosen because the initial solution set off in the wrong direction. The desired goal is now distant. Maybe in Step n, there could be a global check for other minima. Or maybe this accomplishes that trick.
Those who might have noticed an up-tick in the “On the Player”. Not to mention that there is an up-tick in the volume. My wife is away taking care of folks that took care of the country in World War II. Both of them are ok but they want to be independent and strong and some of those things start to fade.
So I am here taking care of the cats (5 neutered males, 2 neutered females, 3 stray males), doing the laundry, dishes, and listening to music that is…not usually permitted.
Challenge: Find a 10 second segment of any 20 second segment of “Dust Devils” that would not make an outstanding ring-tone (not necessarily for you, just for someone). If you have that in mind do not waste you time looking at t’boli or squeal piggy.
Challenge 2: A sub-woofer for a cell phone that replicates the heart-stopping pulse of a car-trunk kick speaker or floor bass.
After a bit of snow on Friday night/Saturday morning, my daughter came down from Asheville in the afternoon. We had supper of spaghetti and salad and music that we rarely get to hear. Sunday, my son came down from school, BLT’s for lunch, naps, daughter changed the oil in her car and we had meat loaf and baked potatoes for supper.
