Yes, and ReCaptcha have always been open about it, before and after being acquired by Google.
From its formation, one of ReCaptcha's main selling points was that the data would be used. At first, it was used for fixing errors and ambiguities in the digitisation of books. Here's an example of this being praised back in 2007, 2 years before Google acquired it,...
There is not much to doubt here. This chip-art seems to have been either common practice or at least a wide spread in-joke among engineers:
Steal the Best

No, walls predate wheels by several millenia.
The invention of the wheel is generally placed at around 3500-4500 BCE. However walls were famously built around the town of Jericho in 8000-9000BCE, so they are at least that old.

The BIC FAQ says the hole in the cap is to prevent children from choking to death.
It was quoted in the question:
The reason that some BIC® pens have a hole in their cap is to prevent the cap from completely obstructing the airway if accidently inhaled. This is requested by the international safety standards ISO11540, except for in cases where the cap is ...
The introduction of the international standard ISO 11540:2014 “Writing and marking instruments — Specification for caps to reduce the risk of asphyxiation” already makes clear that the intention of the design is to reduce the risk of asphyxiation for children.
If a child inhales a pen cap it might become lodged below the larynx and block the trachea. The ...
Yes, GPS requires both general and special relativity to work
[Note this is simplified account based on this and this (MS word download)]
We can understand why by looking at how GPS actually determines where you are. The system relies on a number of satellites transmitting signals and your GPS device receiving those signals (see wikipedia). There are about ...

Most speakers really can work as microphones; the signal is weak, but it is there. See, for example, All speakers are microphones:
What happens is that in a speaker there's a magnet and coil, and a pair of wires connecting it up to something. What is supposed to happen when the device is used for outputting sound that electricity is converted to sound. ...
There is actually some more detail on this on the Java website:
1.1 billion desktops run Java
930 million Java Runtime Environment downloads each year
3 billion mobile phones run Java
31 times more Java phones ship every year than Apple and Android combined
100% of all Blu-ray players run Java
1.4 billion Java Cards are manufactured each year
Luis von Ahn, one of original developers, talked in one TEDx conference about reCAPTCHA technology, and his new Project DuoLingo
In this presentation, he talks about CAPTCHA history and problems and how people were wasting about 500,000 hours every day using CAPTCHA. Then he thought how use this time in a useful thing, like helping OCR books.
It's unlikely that Apple's support for USB had any significant impact on the adoption of the standard.
There are two other events that, in combination, "jump started" USB adoption.
1. Windows 98 release provides comprehensive USB support
Windows 98 was released in June 1998. Prior to Windows 98, USB support in Windows was flaky at best. Support was ...
Yes, but this is a newly reported bug on OS X 10.8.4 and iOS 6.1.3 that affects CoreText API so it will likely be fixed in the near future. The text linked to is the same as appears in a screen shot on the Ars Technica article:
The article then goes on to explain the following:

The video is used as a parody worldwide, it is international and labeled as a "video meme".

On an "energy to move a kilometer" basis, the statement is definitely false.

The question headline seems to be slightly misinterpreting the company's claims
Carefully rereading their claims, I realized they do not specify what Twisted Steel Micro Reinforcement (TSMR) reinforced concrete is better than. On a quick read, I just assumed they meant it is better than rebar reinforced concrete, because that is what the pictures imply, but ...
There was a similar question over on IT Security. I answer here as I answered there, based on my job experience in the alarm monitoring industry. The short answer is that the reverse-PIN system is documented as a possibility, but is not currently in use by any ATM network or manufacturer.
The idea of the reverse PIN is the "duress code"; something that ...
And the mechanical friction caused by the alternator does not depend on whether electricity is being needed or not.
In other words, when energy is not needed it is wasted
Wrong. The electrical energy produced by the alternator is not the result of mechanical friction but of magnetic force on top of the (very small amount of) friction, which ...

Patents are bad for innovation and the economy, more often being a substitute for innovation than an incentive for it
Free-market economists don't normally believe that monopolies are good for society - except where intellectual property (IP) is involved, where they argue that some temporary monopolies are worth permitting to provide an incentive for ...
The radiation is 1000 times stronger
According to Wikipedia The transmission power of a GSM handset is limited to a maximum of 2 watts in GSM 850/900 and 1 watt in GSM 1800/1900.
According to a Radio-Electronics.com article "GSM Power Control and Power Class" the base station controls handset power output in the range 2-19 which is 39 dBm to 5 dBm.
No. A typical home panel might consume the electricity released from about 1/2 a ton of coal. (Update: Or 1/6 a ton of coal, if you use combustion energy rather than electrical generation.)

It depends what you mean by "sold a chip". Intel designs, fabricates and sells a wide range of chips, so for Intel the answer is simple (they don't license out their designs). But ARM doesn't manufacture anything physical. ARM produces the designs for microprocessors. Actual manufacturers such as Broadcom then license the designs, integrate them with other ...

The most accurate method of measuring someone's sleep cycle is to use a bunch of electrodes attached to a person's head - I did this once. It's difficult to sleep this way because the gunk gets in your hair and restricts your movement in the night. However, measuring a person's movement during sleep - which is what all of ...
