Computers Are Infallible -- NOT
A recent article at Kernel Trap entitled
Data Errors During Drive Communication indicates that
"An ongoing study on datasets of several Petabytes have shown that there can be 'silent data
corruption' at rates much larger than one might naively expect from the expected error rates
in RAID arrays and the expected probability of single bit uncorrected errors in hard disks".
This is an interesting read. I used to blame my ocmputer problems on
Random Alpha
Particles. I guess I can now expand my horizons.

Trading Site of the Day -- Teresa Lo: Power Swings
Teresa Lo is a retired securities analyst who has a site called
PowerSwings. Here analytical skills
and powers of commentary show through. Two pages of interest, one on
Volatility and one on
Intraday Trading Strategies are recent articles with some good meat.
For intraday trading, she boils it down to:
- Use small discretionary setups to scalp the first half-hour, especially when the
market is really emotional. I particularly like small flags and gap plays documented in The
Ultimate Trading Course.
- Avoid getting killed after the first hour, when the market usually settles down and
starts to chop. Stay out.
- Get on board the train if it leaves the station in the afternoon for a trend day into
the close.
Once I get into the swing of things, I'm hoping I can break her rule #2, which is where I
think with contrarian Limit orders, one can make money in that sort of market condition.
She also promotes here Ultimate Trading Course. I don't know if it is a good thing or a
bad thing, perhaps someone could let me know.
Her site links to a number of high quality blogs.
WSJ Real Time Economics for one.

If you happen to be the Wiscasset, Maine area, and need a place to stay, try out
Snow Squall Inn. My good friend
Melanie and her husband Paul own and operate the 7 room Bed & Breakfast. I hope to see
them in October and check out their place.

Lighting for Moliere's Sisterhood, the 80's Version
From this month's production of Moliere's The Sisterhood at
Bermuda Musical and Dramatic Society, here are three
shots of the set during the Pre-Show, Intermission, and Post-Show
Decoration cues. During the periods of activity, the set is fully lit, with subtle dimming
of unused area. Unused areas would be the bar and the sofas at various times. This is my
first show where I was lead on lighting design and programming.
The goal of the color splashes were to offset the black and white patterns of the main
set. The color changes were also meant to occur in a somewhat early morning (cool of the
day), mid day (warmer, hot sun), early evening sequence (heavy on sunset colors). The
purple and green in the second were used to highlight the only actor with a color wardrobe,
Trissotin, who had bright green and purple in his clothing.
I used three HighEnd ColorCommand lights to light the French Doors. One light was aimed
at one door from far stage right, one was aimed at the other door from up stage center, and
a third provided a splash across the backdrop from up stage center. The beam width was
adjustable to provide a beam or a wash as I needed.
Although the pictures don't show it dramatically, a purple color splash was 'thrown' on
the red backdrop in the hallway to highlight the phone. A slightly greenish downlight
served to show the phone in stark contrast.
A square shuttered light was used to provide a highlight on the bottles at the bar
throughout the play.
