Japan is implementing similar law in Oct 2015


Is it me or there is serious astroturfing going on in this thread? There are bunch of new accounts with no submissions, 1 comment and 1 karma posting one-liners like:"Awesome","Pretty cool", "Looks interesting"... Just check last 10 accounts on bottom of this thread.


Not really. Have in mind these are retargeting ads. Lets say you visited Shop X and checked out different laptops on that website. Now you are on Facebook and there is post by Shop X in your feed featuring laptop you checked out on discount. Isn't that relevant to your interests? You already showed intent by visiting shop's website.


Microsoft already does this with hotmail.


Clickbank is a joke! I remember year ago you could put in Google product name and "thank you" and you would find thank you page with direct download link.

EDIT: Someone even made CB product to protect thank you page: Fix My Thank You Page http://fixmythankyoupage.com/ only $97 LOL!


I guess Google really started taking advantage of "today's digital internet"

> Adding "no follow" tags to your Robots.txt file is a smart step but it's simply not enough on today's digital internet.


On the old analog internet it worked great.


Fight Club quote: "A new car built by my company leaves somewhere traveling at 60 mph. The rear differential locks up. The car crashes and burns with everyone trapped inside. Now, should we initiate a recall? Take the number of vehicles in the field, A, multiply by the probable rate of failure, B, multiply by the average out-of-court settlement, C. A times B times C equals X. If X is less than the cost of a recall, we don't do one."


Why does Unicode threat Omega and Ohm like different characters?


Wikipedia's article on Ohm actually covers this!

http://en.wikipedia.org/wiki/Ohm#Ohm_symbol

"Unicode encodes the symbol as U+2126 Ω ohm sign, distinct from Greek omega among letterlike symbols, but it is only included for backwards compatibility and the Greek uppercase omega character U+03A9 Ω greek capital letter omega (HTML: Ω Ω) is preferred."

And from the Unicode Standards doc that is the source for that section:

"Greek Letters as Symbols: The use of Greek letters for mathematical variables and operators is well established. Characters from the Greek block may be used for these symbols.

For compatibility purposes, a few Greek letters are separately encoded as symbols in other character blocks. Examples include U+00B5 µ n the Latin-1 Supplement character block and U+2126 Ω in the Letterlike Symbols character block. The ohm sign is canonically equivalent to the capital omega, and normalization would remove any distinction. Its use is therefore discouraged in favor of capital omega. The same equivalence does not exist between micro sign and mu, and use of either character as micro sign is common; for Greek text, only the mu should be used."


Is there a separate symbol for A?


Unicode has lots of characters that look alike, because, well, lots of human languages ended up with similar-looking characters.

Even English speakers will easily confuse 1,I, and l, depending on how they're represented by the browser. And 0/O.

For more fun, try drawing any shape on http://shapecatcher.com/ and see all the similar-looking Unicode characters.


This is a really fun way to explore unicode, thanks.


Because one is a greek letter, and the other is a unit of resistance. The fact that they're represented by the same symbol is irrelevant.


If that were the case, we'd need separate codepoints for every letter used as a unit of measurement, from A for ampere onwards. In fact, it's just there for legacy reasons, as pointed out elsewhere: the convention for units of measurement is to use normal letters, regardless of whether those are Latin or Greek.


Why does HTML have a <strong> and a <b> tag?


<strong> is emphasis/semantic and <b> is visual/style.


The parent was asking a rhetorical question, and drawing an analogy between the two: omega and ohm have different meanings, therefore it might be useful to be able to distinguish between the two. (Note that I say 'might'; when it comes to a character set, I'm not sure I 100% agree ...)


Because they have rather different meanings. Capital omega (Ω, U+03A9) is a Greek letter, with the lower-case form ω; ohm (Ω, U+2126) is a symbol used in electrical engineering with a related symbol "mho" (℧, U+2127).


FYI, that all units measuring physical properties named after scientists use capitalized letters for their abbreviation[1]. So the ohm (named after Georg Ohm) is abbreviated as the uppercase omega, no idea why they are different unicode values, since they do not have different meanings.

Note that omega was probably used so that the 'O' wouldn't be confused with '0', e.g. 4O would be confusing, but 4Ω is not.

[1]The tesla is abbreviated 'T', joule is 'J', etc. etc.


Using the Ohm symbol is actually discouraged. The only reason it's there is for round trip conversion to other character sets.


Facebook also does that!


It's one thing to access Contacts via oAuth, where LinkedIn gets no credentials. It's another thing altogether for them to request credentials and login on your behalf.


There is also another lawsuit filed by interns against Conde Nast for lack of payment: http://www.nytimes.com/2013/06/14/business/media/two-ex-inte...


The author of this article doesn't get NFC.


Quite blatant indeed. They obviously didn't do any research on things like http://tagsfordroid.com/ which is a brilliant use of NFC that could not be duplicated on an iPhone.


I've been thinking about it for a long time. I still don't get it.
