We use which is a clustered Postgres implementation. It has its problems (Postgres 8.2? seriously?) But it is very fast for ETL and batch queries on large data sets. We house 100+TB and get excellent performance. Its commercial and you pay by the TB.

Then there is also AWS Redshift. We have found it to be quicker at some things and possibly cheaper but immature in its feature set (no UDF, etc). The thinking here is that if you have a separate system for ETL, Redshift would make an excellent data warehouse/ data market SELECT server. Pay by usage/ hour.

fdicostanzo writes: Computer programmer Sarah White has been moonlighting a new "therapy" she came up with during which she strips off her clothes. She mentions using the therapy to help (mostly) men with their "schizophrenic existence that is rooted in traditional therapy and exacerbated by the Internet." Would that be worth $150/hr? Might be worth a try although I doubt it's covered by insurance.

There's been some talk that Rackspace's offering has not been up to snuff once you scale. Analysis suggests that Rackspace's offering still has some advantages however.

Jetman Attempts Intercontinental Flight 140

Posted by samzenpus
from the a-jetwing-and-a-prayer dept.
Last year we ran the story of Yves Rossy and his DIY jetwings. Yves spent $190,000 and countless hours building a set of jet-powered wings which he used to cross the English Channel. Rossy's next goal is to cross the Strait of Gibraltar, from Tangier in Morocco and Tarifa on the southwestern tip of Spain. From the article: "Using a four-cylinder jet pack and carbon fibre wings spanning over 8ft, he will jump out of a plane at 6,500 ft and cruise at 130 mph until he reaches the Spanish coast, when he will parachute to earth." Update 18:57 GMT: mytrip writes: "Yves Rossy took off from Tangiers but five minutes into an expected 15-minute flight he was obliged to ditch into the wind-swept waters."

Comment: Apple 2 video game (Score 5, Interesting) 174

I remember the old Prisoner 2 video game for the Apple II. They gave you a secret number and all you had to do was not give it to them when they asked. Sounds easy. Just don't type the number.

Well, they got me! Applesoft programs would sometimes crash into prompt with an error and line. One would almost instinctually list out the line to see what the error was. So when the video game seemed to crash I listed out the line..... You lose!

I have never enjoyed losing a game so much.

On a recent trip to Jamaica, we had some tiny little ants in a nest in the bathroom wall. I discovered that they wouldn't cross invisible Vaseline lines rubbed on the wall.

Well, after a few days, I had created complex Vaseline mazes for the ants with food smudges at strategic locations. Got them to spell out my name with their ant trails. Wife wasn't as impressed as you might imagine.

Beaches were nice too.

I don't believe most roads change color because of tire rubber- excepting a few high traffic areas. Most change color to match the aggregate (read: rock) that's in in the asphalt- usually some sort of plain greyish rock.

When I drove through AK/CD the roads are green or red or other colors that match the color of the local rock they used.

Perhaps all they need to do is use a bright white rock in the aggregate?
