.backup files opened!!!!

2012-01-23T14:43:00.000-05:00

I don't know whether this will work for everyone, but a wonderful Apple tech support person puzzled out that my .backup files could be read by changing the extension to .dmg

That was it. Whew!!! I'd been trying for weeks to recover my information.

Backup was part of the Macintosh OSX system before Time Machine. Backup is no longer supported under OSX Lion, or even Snow Leopard, and no one seemed to know any way to get to the files. The Backup program is still on my computer, but it was confused and wouldn't open the files.

BUT!!! Changing the extension from .backup to .dmg was all it took to have my files open up in the CopyWrite application in which they were created.

Thank you, Matthew at Apple Tech Support!!!!

Here it is again. Written by Orson Scott Card, spoken by Ender (son of Bean, now known as the Giant, in Shadows of Flight.) This is the character who appears to be sympathetically narrating the author's philosophy."We're still primates, only a few genes away from the hairless chimps that began to cook their food so that women stayed by the fire to do the cooking while their monogamous mates ranged and hunted to bring home meat. And only a few genes farther from the hairy chimps that mated whenever they could, usually by force, and lived in terror of displeasing the alpha male."Why is everybody STILL searching for a genetic causality to the difference between those two life behavior sets?IT'S NOT IN THE GENES. It's in society, in the huge sets of behavior codes in mimicry and procedural memory. The sets are recorded in procedure, accessed by individuals who live in society, and evaluated within these individuals by hierarchical comparison, and occasionally, where there is balance, by the "human" ability to make a new choice based on perception of "good."

Song: Three Angolan Women sing in Life in a Day

This song and the video segment of three young women singing as they pound grain together is stunning, both in its freshness and in the sense of what is completely lost in worklife in the USA. Are we even trying to regain the companionship and artistic freedom inherent in simple work, for which we no longer have "time?"

Abstract: Year-round schooling

2011-12-08T18:52:00.000-05:00

Calendar Effects

Melissa McCartney

Does the organization of the school calendar affect student learning? Year-round schooling, which distributes school days with short, frequent breaks, is becoming more popular because it is thought to prevent the summer learning loss that occurs under a more traditional school calendar. Using longitudinal data from California public schools over a 9-year period, Graves examined the effect of year-round school calendars on nationally standardized test performance of traditionally disadvantaged students. Analysis showed that year-round calendars, especially multitrack year-round calendars in which the student body is never all in attendance at the same time, have a larger negative impact on the lower end of the distribution of scores, with Hispanics/Latinos and low-socioeconomic status students experiencing a larger fall in performance than the overall population. African American students are more negatively affected than the overall student population with respect to reading. Policy-makers take note: These results present an additional cost of implementing year-round calendars.

e-Genius wins Lindbergh Prize for Quietest Aircraft

Posted on October 2, 2011 by Yolanka

The e-Genius team, with Erik Lindbergh and Yolanka Wulff of LEAP, winning the Lindbergh Prize for Quietest Aircraft

Erik Lindbergh, founder of LEAP, announced the first winner of the Lindbergh Prize for Quietest Aircraft at the NASA Green Flight Challenge. The prize was awarded to e-Genius, a two-seat electric airplane piloted by team leader Eric Raymond and Klaus Ohlmann. The plane was designed and built by University of Stuttgart Institute of Aircraft Design under the direction of Professor Rudolf Voit-Nitschmann and his assistants Len Schumann and Steffen Geinitz. Take off noise levels of the competitors ranged from a minimum of 56dBA to a maximum of 72dBA. e-Genius won with a takeoff range of 56 – 62dBA. By comparison, the takeoff noise of a turbo-fan aircraft at a similar distance is 110dBA, over 16 times louder.

We're here at the NASA CAFE Green Flight Challenge on the third and final day of testing. The initial thirteen teams are down to four participants – three competitors and one demonstrator. Two all-electric planes are flying: e-Genius from Germany and Pipistrel Taurus G4 from Slovenia. An efficient piston plane, the PhoEnix from the Chech Republic, is the third competitor. And the first electric hybrid plane, Embry Riddle Aeronautical University's EcoEagle, is flying as a demonstrator.

Pat Anderson of Embry Riddle Aeronautical University explains the workings of the EcoEagle to Erik Lindbergh and Jean Schulz at Charles M. Schulz Airport

Against the noise of the planes and jets taking off in the background, the silence of these planes is amazing. To emphasize the importance of this attribute of electric flight, on Saturday night LEAP will announce the winner of the first annual Lindbergh Prize for Quietest Aircraft at a celebration banquet hosted by CAFE Foundation. For more information about this prize, go to www.lindberghprize.org .

While the testing was not open to the public, there are plenty of media here to capture this history-making event, and we'll post video to this website in the near future. On Saturday, there will be an all-day public open house here at Charles M. Shulz Sonoma County Airport. Be sure to come out and see these incredible planes, and the people who have designed, built and flown them.

On Sunday the planes will move to Moffett Field for Monday's Google Green Flight Expo hosted by NASA Ames. The winner of the Green Flight Challenge will be announced at noon on Monday at NASA Ames. http://www.nasa.gov/centers/ames/events/2011/10_03_11-expo.html

Women Soaring Seminar Returns to Chilhowee

2011-11-22T22:12:00.000-05:00

Women Soaring Seminar Returns to Chilhowee

The Women Soaring Pilots Association (WSPA) is pleased to announce that the Chilhowee Gliderport will host the 2012 annual Women Soaring Seminar, June 25-29.

Chilhowee Gliderport is located five miles north of Benton, Tennessee, in the southeastern part of the state near the Great Smoky Mountains. The area is extremely scenic, with a number of activities for nonflying spouses and families, including white-water rafting or kayaking on the Ocoee River, canoeing on Parksville Lake, or floating down the more leisurely Hiwassee River. The trails of the nearbyCherokee National Forest are perfect for hiking, with beautiful views and waterfalls.

The Women Soaring Seminar, a tradition since 1979, provides a venue each year for both women and men to increase their skills, meet other glider pilots, and advance the sport. It brings together WSPA members from all over North America and Europe. Activities are planned for every skill level, from pre-solo students to advanced cross-country pilots. The atmosphere is fun and non-competitive, with an emphasis on safety and skills development. Past seminars have featured specialized flying experiences like organized land-outs, mini-competitions, dual cross-country, and badge/record work.

A registration form is available at www.womensoaring.org. For more information about Chilhowee Gliderport and local lodging, call (423) 506-9015.

Quote:

"Chilhowee is one of the best seminar locations in the East," said WSPA President Neita Montague. "It is located adjacent to an undemanding ridge, which gives participants an additional source of lift for stretching their cross country distances. I recommend it for any glider pilot who wants to receive training or practice in ridge soaring techniques."

Happy Birthday, Nat!

Ti chart for sunday october 30

2011-10-30T22:27:00.001-04:00

There was lift, but not a lot. Lee and Osaki had to go twice to find any. They and Hugh and Bob and Steve eventually got good flights. Herb was up a long time, but was "hugging the airport."
I got in three flights, pattern practice. Gary flew solo in the 2-33 and in another glider.

Thermal Index (How To)

2011-10-29T21:25:00.001-04:00

To figure out the thermal index, use Foreflight:

Airport: KBRY –> Weather –> Winds Aloft.

It usually makes sense for us to use the 2 pm (1800Z) prediction.

In two columns, jot down Altitude and Forecast temperature in Cº.

Alt: Temp:

9,000 -7ºC

6,000 -4ºC

3,000 +2ºC

surface -----

Then add a third column by writing down the maximum temperature expected that day at the surface
(in this example, 58ºF = 14ºC)

Alt: Temp:

9,000 -7ºC

6,000 -4ºC

3,000 +2ºC

surface ------ 14ºC

Then use the Dry Adiabatic Lapse Rate of 3ºC per 1000 feet (9ºC per 3000 ft) to figure the theoretical temperature that a 58ºF parcel of air will attain as it rises thru the atmosphere, cooling as it goes.

Since our airport is 700ft MSL, not sea level, the first calculation will be 14ºC - (2.3 * 3º) to make the 3000ft prediction.

2.3*3º = about 7º that will be subtracted from the max temperature for the day.

So for the 3000 ft TI, 14º - 7º = 7º.)

Alt: Temp: Parcel

temp:

9,000 -7ºC

6,000 -4ºC

3,000 +2ºC 7ºC

surface ----- 14ºC

For the rest of the layers, just subtract 9º from each lower level temperature.

Alt: Temp: Parcel

temp:

9,000 -7ºC -11ºC

6,000 -4ºC -2ºC

3,000 +2ºC 7ºC

surface ------ 14ºC

Now, we make the fourth column, the "Thermal Index," by computing the difference between columns 3 and 4.

Alt: Temp Parcel TI:

temp

9,000 -7ºC -11ºC +4

6,000 -4ºC -2ºC -2

3,000 +2ºC 7ºC -5

surface ------ 14ºC

A thermal index of between -2 and -4 is necessary to get enough lift to carry a glider. Any larger negative number is even better. So, the index indicates good lift at 3000ft, and perhaps up to 6000ft, but not higher.

Thinking about cursive writing

2011-10-16T09:24:00.000-04:00

If schools are permitted to teach a pre-cursive alphabet from the outset, this conversation is happily re-directed into one about quality time. Look at the DeNelian alphabet, which many educators prefer. It starts students with fluid adult movements. It completely avoids the difficulty of those b's and d's, p's & q's that were introduced artificially a century ago (remember making letters with ball and bat?). It then becomes cursive at a natural pace, with only a little prompting from the teacher, and sufficient time to write in either stage.

Parents, teach this to your children yourself, and encourage the schools do it as well.
