Welcome to the 458th issue of the PC Improvement News. PCIN consists mainly
of news highlights and tips. There is something for everyone, and if this is
your first issue, I'm sure there will be something for you. If you give me
two or three issues, I know that you will come back for more!
Andrew is turning 5 on Friday. I can't believe our
first baby is going to be 5! We're going mini-putting on Friday, and
then on Saturday he is having his first friend birthday party (with a mini-putt
theme of course... he loves miniputt!). He's obviously very excited.
Last Saturday there was a special 30-minute long fireworks display in Niagara
Falls. I took some pictures
and posted a video if you are interested in seeing some of it.
FBI ducks questions about its remotely installed spyware
There are plenty of unanswered questions about the FBI spyware that, as
we reported earlier this week, can be delivered over the Internet and implanted
in a suspect's computer remotely.
Many of the questions hearken back to the old debate over the FBI's Carnivore
wiretapping system, which technical luminaries Steve Bellovin, Matt Blaze,
David Farber, Peter Neumann, and Eugene Spafford raised in a December 2000
And of course there are issues more specific to the FBI's use of the Computer
and Internet Protocol Address Verifier, or CIPAV, including whether the bureau
believes it can install it on Americans' computers willy-nilly in the wake
of a wacky 9th U.S. Circuit Court decision this month.
Does your company monitor how much time you spend on YouTube and eBay? Perhaps
Employees waste more than 81 minutes of work time in personal computer activity
on average and 13% squander more than two hours a day on recreational computer
activities, according to an old AOL/Salary.com survey.
And, those considered top employees can be the worst offenders.
The perfect game of checkers ends as a draw, Canadian computer scientists
reported on Thursday.
The team at the University of Alberta said they had "solved" checkers,
the 5,000-year-old popular board game also known as draughts. Their computer
program, Chinook, spent more than 18 years playing out the 500 billion possible
positions, they report in the journal Science.
On a muggy day in Kigali in 2003, some of the highest-ranking officials
in the Rwandan government, including President Paul Kagame, flanked an American
businessman, Greg Wyler, as he boldly described how he could help turn their
small country into a hub of Internet activity.
Mr. Wyler, an executive based in Boston who made his fortune during the tech
boom, said he would lace Rwanda with fiber optic cables, connecting schools,
government institutions and homes with low-cost, high-speed Internet service.
Until that point, Mr. Wyler, 37, had never set foot in Africa - he was invited
by a Rwandan government official he had met at a wedding. Mr. Wyler never
expected to start a business there; he simply wanted to try to help the war-torn
Even so, Mr. Wyler's company, Terracom, was granted a contract to connect
300 schools to the Internet. Later, the company would buy 99 percent of the
shares in Rwandatel, the country's national telecommunications company, for
But after nearly four years, most of the benefits hailed by him and his company
have failed to materialize, Rwandan officials say. "The bottom line
is that he promised many things and didn't deliver," said Albert Butare,
the country's telecommunications minister.
Colour Relationships - Digital Photography Tip of the Week
Today's tip is a quick one regarding the relationship of colour models. You
are most likely most familiar with the RGB colour model as this is used in
most computer applications, your digital cameras, monitors, etc. Another very
common colour model comes from the print industry, CMYK. If you are using Adobe
Photoshop Elements, you only have access to the RGB colour model. If you
are using the full version of Adobe
Photoshop (any recent version) you will have access to many different colour
models including RGB and CMYK.
They both get their names by using the first letter of each of the colours
needed to represent all of the other supported colours in the model. RGB uses
Red, Green and Blue to make up the other 16.7 million colours this model can
represent, while CMYK uses Cyan, Magenta and Yellow to make it's colour gamut.
CMYK also need to add in a fourth colour - black - to fully achieve the depth
needed for some of it's colours though that is not important today.
If you are unfamiliar working with CMYK, it can be a bit confusing. However,
there is a little bit of correlation between the two that becomes especially
useful to know when you are performing colour corrections.
R - G - B
C - M - Y
When you are colour correcting an image, if you know what colour the colour
cast of the image is, you can correct it by adding the corresponding colour
from the other colour model. For example, if you image has a cyan cast to it,
adding red will help eliminate it. On the other hand, if your image is on the
green side, slowly adding magenta will compensate for that green.
People are very sensitive to variations in colour when they see it. Keeping
colours correct can help ensure you photos look as they should.
