Trying to check whether the cached version of Amnesty International is reachable in China, I found that the system returned an error message stating that the Great Firewall blocks requests only by URL and thus the parameters should be removed from the request. Apparently, the server containing the cached page, "http://216.239.37.100/", can be reached from China.
I am inclined to think that the Chinese Government may already have more subtle methods to block content. On the other hand, they keep shutting down internet cafes...
You got a point. There still are a couple of problems:
*Providers need to make sure that IP phones are assigned a "normal" phone number so that they can be called from telephone booths, the Virgin Islands, Siberia, etc.
*There needs to be a certain degree of stability and security, i.e. if they use wireless or fixed wireless networks, they need to restrict access to their broadcasting equipment and use redundant power supplies. Remember, good ol'telephones (simple ones) receive their power from the telco's network and are thus somewhat immune to blackouts (in case of fire, for example).
I would think that the speed of scanning and the space needed spoke against the use of 3D-barcodes for groceries.
At least here in Europe, the last digit (AFAIK) is a kind of checksum to verify that all the other digits were read correctly. I am inclined to think that this speeded up the scanning process quite a bit.
I would think that longer barcodes - with 25 digits, for example - would be more of a disadvantage to supermarket chains as they would cause a large increase in network traffic while slowing down the customers when the cashier has to enter a number manually.
Are you asking this question because it is a nice philosophical one or did you actually discover something?
Chances are, it might take us decades to make use of it.
Furthermore, what makes you think that, say, in the next couple of decades, no one else will make that discovery?
When a power company has a lot of hydroelectric power plants, it is common to use power stations with reservoirs because they can make the excess energy that is produced at night available during the day. Seemingly, it is cheaper for the power companies to use stations with reservoirs than to generate power from other sources like thermical power plants (which burn fossil fuels). Additionally, this is an ecologically friendly solution.
"About the euro design, it is clear that color vision deficient people have not been taken into account."
For everyone who has already paid with euros, this is obviously nonsense.
Euro coins can be distinguished by
the shape of the edge
their size and
their thickness
in addition to the color of the alloy(s) and the number. While it may be feasible that euro coins can be used for testing against color blindness, the statement that color-blind or blind people cannot distinguish between coins of different values is to be considered wrong.
I have to admit that many had problems adjusting to the new currency, but these problems were primarily related to the conversion between values rather than to the new coins and bank notes themselves.
It might be true, however, that blind (not color-blind) people have problems because every country can design one face of each coin (the other face is the same in all countries). However, about 90-95% of the coins that circulate here in Austria are Austrian euros.
Having spent a couple of months in the US, I find that US coins are harder to distinguish than euro coins as they are all made of a cupro-nickel clad and thus have the same color (except for the Cent which is made of copper-plated zinc). Additionally, the fact that the denomination is not clearly stated on the coins and that they're called "dimes", "quarters" and "nickels" cause a lot of confusion in the beginning.
As for the statement that the composite 1- and 2-Euro coins may fall apart easily in the freezer, I have to say that some European countries have had composite coins before and that I have not seen any coin where this has happened.
I'd say that it is easier to distinguish between different currencies than between dollar bills of different denominations. After all, they're gonna have different styles, sizes and so on.
The Euro has made a lot of problems disappear.
(after all, I don't need to buy D-Marks or Dollars any more when going to a foreign country.)
I guess at least some of you have already heard about the OQO, a more or less handheld device running Windows XP (or maybe Linux, too). Here's what they say:
"The projected price will be less than most notebooks even with OQO's full set of wireless communications." "The first product will be available in the second half of 2002."
Now, even though it doesn't really qualify as a PDA (size and price), it'll be a nifty gadget.
I wonder why he does it with a cron job - any simple timer would do it too (and it'd be less likely to crash). Does he do anything freaky with it, like, for example, have the computer automatically switch it off and on according to calculated sunrise and sunset times?

Then, it'll be really difficult to fire network operators!
Nevertheless,
www.google.com works, as do
images.google.com and
groups.google.com.

...but I'd prefer the real thing! ;-)
Just because you're American doesn't mean the rest of the world has to follow your rules.
Don't you think that 712,49 $ are a bit hefty?
Not for the Japanese, maybe.

So you need to boot up your computer if you're going to receive a call? How would you know? Telepathy?
;-)
Note to those running servers at home: I wouldn't like to have one next to my bed
And those IP phones are quite expensive.

Nice gadget, really. On the other hand, I doubt I'd buy one as I don't have a lot of tapes. And for car radios, there are cheap adaptors around.
Have a politician print it in his/her campaign material.
No intelligent person can take that what's printed in there serious.

So my whole DVD collection will fit onto 1 cm ;-)

I agree with you.
Moreover, would you like a computer virus/hacker to turn your apartment into a sauna?
The cellphone-tv combo would have certainly been a nice gadget for the Football World Championships. Hey, maybe it's ready 'till 2006.
Funny kind of calculator you have... Well, it works well with Palms.
