/A database (DB) is as fast at data retrieval as it's connection. On a
local drive this can be very fast. If the database is accessed via the
internet it can be quite slow, no matter what the relational design. Most
very large databases use Oracle software. Any database that is accessed via
WI-Fi is highly susceptible to hacking.
According to the hacker ethic, any internet database (DB) should contain
information freely accessible to the public. /

/THIS REMINDS ME THAT I HAVE TO SET UP AN "EVENING
OUT AT THE PUB" WITH A FRIEND OF MINE HERE, WHO WORKS FOR THE ESA
(EUROPEAN SPACE AGENCY) ON TWO DIFFERENT PROJECTS THAT HAVE GOTTEN A
MENTION HERE LATELY. FIRST, AND MOST IMMEDIATELY RELEVANT, HE WAS IN
CHARGE OF THE DATABASE OPERATIONS FOR THE ROSETTA PROJECT, SO I'LL ASK
HIM WHAT'S UP NOW THAT PHILAE HAS ROLLED AWAY THE STONE AND COME BACK TO
LIFE./
/BUT THE OTHER, MORE LONG-TERM PROJECT HE WORKS ON IS THAT HE IS
IN CHARGE OF THE DATABASE USED TO STORE INFO ON COMETS, ASTEROIDS, AND
OTHER SPACE JUNK THAT MIGHT HIT THE EARTH. SUFFICE IT TO SAY THAT THIS
DB IS *HUGE*, AND PRESENTS SOME PROBLEMS WE'VE DISCUSSED BEFORE (I USED
TO WORK IN DB, AND WAS CURIOUS) ABOUT THE RELATIONAL DESIGN OF THE DATA
AND ISSUES HE MIGHT FACE WITH OPTIMIZATION AND SPEED OF RETRIEVAL./

SUBJECT: [FairfieldLife] Philae only playing possum
The European Space Agency (Esa) says its comet lander,
Philae, has woken up and contacted Earth.
Philae, the first spacecraft to land on a comet, was
dropped on to the surface of Comet 67P by its mothership, Rosetta, last
November. It worked for 60 hours before its solar-powered battery ran
flat. The comet has since moved nearer to the Sun and Philae has enough
power to work again, says the BBC's science correspondent Jonathan
Amos.
An account linked to the probe tweeted the message,
"Hello Earth! Can you hear me?" On its blog, Esa said Philae had
contacted Earth, via Rosetta, for 85 seconds on Saturday in the first
contact since going into hibernation in November.
We don't leave anyone behind.
