If you think you've anonymized a data set, you're probably wrong




It’s too bad the Cash Cab is no longer running. This could potentially be used as a way to track it and find the best times and places to catch it.


" income of ever hack"
“figured out which who goes”

Cripes, typos galore methinks :slight_smile:


I’ve heard cabs referred to as “hacks”, but usually only in the UK. I think it’s a bit of colorful slang.


Hacks wouldn’t be in the dataset as a hack is someone who drives an unauthorized taxi.


Definition of HACK: (1) : taxicab

Hacks or Hackers is a common term that originated with the hackney horse,[3] a breed of horse typically offered for hire in the 19th century.


I thought he was tracking the bottom feeding celebrity chasing ‘journalists’.


And drives it poorly, after being paid to perform unorthodox modifications upon it, writing about it for the press, and doing so for political gain.

::cough cough::


Indeed, but surely it would be ‘every hack’ not ‘ever hack’


I think the typo is “ever”, not “hack.”


I wonder if the not tipping celebrities in the post’s excerpt are instances of cabbies not reporting their tips. Ever wonder why the credit card machine is always broken?

I could be wrong, but I’m pretty sure the dataset doesn’t record tips if the passenger paid the fare in cash. So it’s quite possible Mr. Cooper and Ms. Alba are good tippers, but just didn’t pay with credit cards.


It’s better to pay tips in cash. Electronic processing often has mechanisms to take out various cuts and does not let the tip recipient to keep it all.


EverHack is the phone app you use to take notes about your cab ride and share them with your friends and colleagues.


Yes, the NYC taxi credit card machines reportedly take 5% of everything. Initially hacks were very resistant to letting customers use them because they didn’t want to give up those fees, but after a while they stopped complaining because they realized that the “20%” button on the credit card machine got them much better tips on average than people rounding up a dollar or two from the cash fare–even after giving up 5% of the gross amount.

One other interesting note about NYC taxi credit card machines is that different vendors’ machines calculate the tips on different bases. The Verifone machines, for example, don’t include the $.50 NYS surcharge when calculating a percentage tip, while the Creative Mobile machines do, so if you routinely hit the 20% button, a Creative Mobile taxi will always be $.10 more expensive than a Verifone taxi.


Ah, didn’t know that one. :smile:

In this case though, it was a typo, i noticed the original article has corrected them now.



so much this.

in the service industry, we have a few slogans about this:

“Cash is king”
