San Francisco: John Thys still has not figured out how much his company has paid Google Inc for bogus sales referrals caused by 'click fraud' - a sham aimed at a perceived weakness in the Internet search leader's lucrative advertising network.
But Thys says he has uncovered enough of it to conclude that Google is trying to shortchange his company and thousands of other advertisers by offering refunds totaling $60 million to settle a lawsuit.
"It's almost like an insult that they expect us to take this token money," said Thys, director of Internet marketing for Radiators.com.
Google also expects to pay $30 million to the lawyers who settled the case on behalf of advertisers, raising the settlement's total value to as high as $90 million.
An Arkansas judge is expected to consider the proposed class-action settlement in late July.
The refunds, which will be provided in the form of advertising credits, are meant to compensate Google's customers for undetected click fraud, which contributed to the $13.3 billion in ad revenue that has poured into the company since 2001.
Google's offer works out to a $4.50 refund on every $1,000 spent in its vast advertising network over the past four-and-a-half years.
Meanwhile, independent studies assert that anywhere from $100 to $400 of every $1,000 stems from click fraud.
If those estimates prove correct, Google might be on the hook for $1 billion to $5 billion in advertising refunds

its like paying 4.50$ for every 1000$ back... Hmm...lets google the money ;)

RFID Systems

what are the components of a RFID System?

The basic RFID system consists of three main components , the coil, the transponder and the decoder (transreceiver). The coil works like an antenna to emit radio signals which inturn writes and reads the data that is available on the Tag.

The Tags can be classified into two parts active and passive tags. Active tags are those tags which have a battery source installed into the tag and are usually read/write, whereas the passive tags are read.

The tags can be further classified based on the frequencies which are LHF, HF and UHF. The LHF can have the frequency anywhere from 30Khz to 500 Khz, the HF from 850 Khz to 950 Khz and the UHF will have from 2.4 Ghz to 2.5 Ghz. More the frequencey they become microwaves.

RSI manufactures sub-15 cent gen2 RFID tags

The RFID tags cost have come down to sub 15 cents. The prevailing rates are 40 cents per tag now, but RSI promised to give us tags sub - 15 cent. The constraint being we need to order 1 million tags => this equals = .15*1000000 = 150,000 $.

The RSI also claimed that there is no reduction in standard or quality. So, this cost cutting should have been due to some of the best manufacturing practices that would need to be followed by RSI.

So let us think of a scenario where the 40 cent tags are a fixed cost and .15 comes due to the variable cost for 1Mn and <1Mn its 40 cents. So the graph would look like the one on the right side.

The cost is expected to come down to 5 cents in next 3-4 years and the way to do that is better production models.

Probably, we should start manufacturing it in India for better cost effectiveness? Mr. Murthy can u give me a chance to own this ?

Gmail and Privacy issues

I have a Google Gmail Account, and i found that there are privacy issues with Gmail.

the story goes like this...

I have an email id which is like xyz.abc@gmail.com and there is one another interesting friend of mine who has an email id xyzabc@gmail.com . All the emails (read it as confidential emails) comes to me which are written for xyzabc@gmail.com to me who is xyz.abc@gmail.com.

Its a great privacy issue for Google and i dont know how many gmail users are doing this. I now realize what the slogan on the american dollar bill is
