If you Google "Solar and climate signal records in tree ring width, from Chile (AD 1587-1994)" You find an article with similar findings from 2006.
The most interesting thing about this is not the 11 year cycle that the
Brits in the previous email found this year, but the 50, 100, amd 200
year cycles that these guys found in 2006. If solar activity (and
hence cosmic rays) is measurably affecting tree growth, what else is
being affected. Also important is that this paper shows it is not just
historical accounts about the lack of sunspots at the time that can be
correlated with the Maunder Minimum (little ice age), but now there is
concrete data correlating it with cosmic rays (through the measurement
of C14 and Be10).
This is the kind of thing that GW people want to sweep under the rug
because it puts their CO2 claims into doubt.
Abstract
Tree growth rings represent an important natural record of past climate
variations and solar activity effects registered on them. We
performed in this study a wavelet analysis of tree ring samples of
Pilgerodendron cupressoides species, from Glaciar Pio XI (Lat: 491120S;
741550W; Alt: 25 m), Chile. We obtained an average chronology of about
400 years from these trees. The 11-yr solar cycle was present during the
whole period in tree ring data, being more intense during Maunder
minimum (1645\2261715). The short-term periods, around 2\2267 yr, that were
found are more likely associated with ENSO effects. Further, we found
significant periods around 52 and 80\226100 yr. These periodicities are
coincident with the fourth harmonic (52 yr) of the Suess cycle (208 yr)
and Gleissberg (80\226100 yr) solar cycles. Therefore, the present analysis
shows evidence of solar activity effect/modulation on climatic
conditions that affect tree ring growth. Although we cannot say with the
present analysis if this effect is on local, regional or global climate,
these results add evidence to an important role of solar activity over
terrestrial climate over the past 400 yr.
Excerpt from text:
Techniques using cosmogenic isotopes permitted the reconstruction of
solar activity variations on longer timescales. Two isotopes are
commonly used, carbon-14 and beryllium-10, both produced by cosmic rays.
Galactic cosmic rays are modulated by changes in the strength ofthe
interplanetary magnetic field arising from changes in solar activity
(Hoyt and Schatten, 1997). The existence of century scale variations
caused by solar activity has been confirmed from 14C dating (Stuiver and
Quay, 1980) and 10Be ice-core data (Beer et al., 1988). The Sun\222s
long-term behavior also shows transient dynamics such as the Maunder
minimum from AD 1645 to 1715 (Eddy, 1976),
Results and discussion:
The periods analyzed in this work are: (1) 1587\2261994 in tree ring
chronology, (2) 1610\2261994 in Rg and (3) 1876\2261994 in SOI. In order to
identify the main periodi- cities in each time series and study its time
variation, wavelet spectrum was determined for Rg, SOI and tree ring
data using the 95% confidence level contour (Torrence and Compto, 1998).
Fig. 1 shows the wavelet spectrum for the Chile tree ring data. It shows
a signal associated to the 11-yr solar cycle and fourth harmonic (52 yr)
of the Suess cycle (208 yr), in the interval 1645\2261715, and a strong
signal associated with the Gleissberg ($80\226100 yr) solar cycles between
1720 and 1860. Fig. 1 also shows others signals in the 2\2268yr band, which
are visible with more intensity for interval between 1616 and 1742 and
weaker for interval between 1830 and 1950, approximately. This may be an
indication of the response of the tree rings growth to environmental
conditions at their location.
Fig. 2 shows the wavelet spectrum for the Rg. The signal near 11-yr is
the strongest feature and it is persistent during the whole period, with
higher intensity in the period 1940\2261994
Maybe it's because women are too practical, or have better things to do, than to code for free, as suggested by this comment on TFA:

It's unfortunate that you're getting beat up over this. While I have not participated much in FOSS aside from using it, I do work for a tech giant,...
So maybe this blogger should mind his own business.
Possibly you missed the part about LSE was going against the grain by using windows for this kind of system, when everyone else was using Unix or Linux, and the MilleniumIT system is proven.
Maybe I didn't RTFA well enough, but also didn't get it, why a BSD blog is singling out linux. What about all the other *nixes. Was there something has was trying to say that only applies to linux?
PS. FWIW Solaris doesn't allow root network logins by default. That plus a packet filter will prevent anyone from logging in from other than home or office.
Except that Ballmer has told analysts and investors that they need to put Win7 on the netbooks so they start raking in the dogh again, but the price of the machines has to come up before they can sell the pricier OS.
Now, what about the camera being on the wrong side? Would anybody want that knowing they're screwed with Skype?
We can expect that internet access technologies will be decided by and controlled by the usual corporate suspects to maximize profits. Grassroots co-op networks are needed but missing the technology. BTW here is a link to the print version of the article (it's still Mohawk, though).
The sealed drives we use now showed up in the '80s. Before that the platters were not part of the drive, they were in a plastic cover to keep the dust off. On the mainframes the cover held a stack of platter; on the minis there was just one or two 5mb platters inside. We would place the whole stack with cover into the drive, then rotate the handle to pull the cover out, leaving the spindle of platters in the drive. Then just close the dorr and push the button to spin it up. In either those old open ones or the "new" sealed ones, the head flies on a cushion of air, but the distance from head to platter is microspic; a piece of dust is big in comparison. In the old open drives, if the head hit even a tiny piece of dirt, it could "crash" into the platter and gouge out a rip. If you haven't heard it, it was actually fairly loud and startling.
TFA mentions that Google Chrome OS should support ARM, so since we already see Google Phones with Android and Google Apps, I don't think it's overly optimistic to hope to see a "GoogleBook" or Google Tablet.
to explaining the common misperception of Unix or Linux as a "server OS".
Unix was conceived as an interactive environment for programming, and is sill the only OS worth using for a programmer
Sun started in business selling workstations running Unix, later modified BSD to create SunOS, which eventually became Solaris. Sun Microsystems
And, as you're alluding to, in the beginning Linux was something fun to play with on the desktop.
But then the WWW came along and the only OSes up to the task were Unix based or Unix like. And, "Windows" certainly never was a "server OS", but it's good for spreadsheets, so in certain types of people's minds "It's a Server OS".
Specifically, its atoms sit at the vertices of four-sided pyramids. Each atom behaves like a tiny bar magnet, and when the crystal is cooled to near absolute zero, the atom-magnets align. Sometimes, three of the pyramid's four corners align together and create a region of north or south magnetic charge at the centre of the pyramid. The charge isn't attached to any physical object, but it behaves just as a monopole would.
I don't want to pay money to read a NS article, but this quote seems to be the key. I get the impression, that as opposed to everyday magnets which always have two "poles", the alignment of these pyramid vertices creates a virtual pole in the middle which has no complementary opposing pole.
This probably does not really address the true long term trends. RDB and SQL are truly old tech and due to be replaced.
And in some applications (eg. Bigtable) they are being supplanted.
But RDB is mature and widely accepted to the point that it takes special applications or, just very free thinkers, to consider using something else.
That will change over time, but not quickly.
You are right, but regarding EC vs. US competition, eg. Boeing and EADS, it's all in good fun. Except in this case it's
Oracle vs no EU competitor
Sun vs no EU competitor
Microsoft vs no EU competitor
Most American companies vs no EU competitor
So now the stupid overpaid worthless bureaucratic asslicks lolling around in their comfy EC jobs can fuck around with foreign companies to the point that the foreign companies are uncompetitive.
Nice work

Maybe not. The fact the most of the other exchanges use Linux indicates that they knew something that LSE didn't.
