If you look at the last two pages of this classic paper (admittedly almost 20 years old now), you’ll see a list of some names they used in the field experiment. https://www.nber.org/system/files/working_papers&#x2F

You could consider the Keyboard FeatherWing. It contains only the screen and keyboard part. You are meant to add a Feather format board that has a microcontroller and Wi-Fi, for example Adafruit’s ESP32 Feather board. https://www

What’s a little frustrating with the Xilinx parts listed on Digi-Key, and to some extent other FPGA vendors, is the lack of any price breaks. I looked up a random i.MX6 processor from NXP. It’s $32.08 for one of them, and $20.95 per part wh

I am not aware of countries that test completely randomly. But many countries have so-called sentinel surveillance, where 1-5% of family doctors (general practitioners) send in samples to a lab from patients who appear with influenza-like o

In the US, the most common ACH debit and credit transfers can be “returned,” which is similar to a chargeback. This is covered by Subpart A of Regulation E of the Federal Reserve. Only “wire transfers” such as Fedwire and SWIFT transfers, w

I tried it, and it appears to be freemium. The basic level is WARP, and then there’s WARP+ which costs $4.99/month. The difference isn’t entirely clear though. It says that WARP+ will “route your internet requests to avoid Internet tra

In the case of Ouigo, I believe it’s in part because the station and track owner charges less to use peripheral stations than for central stations, and in part for price discrimination, so less price-sensitive business travelers and wealthi

The French state railway company SNCF has a low-cost service high speed TGV service called Ouigo that also uses stations on the periphery of some cities (while regular TGV goes into central stations), just like low-cost airlines.

For land producing minerals, there is a special tax rule called “percentage depletion” available to some taxpayers. With percentage depletion, the owner can deduct a fixed percentage (15%) of gross income every year. This can add up to more

It’s pretty common. If you pay a lot of household bills—for electricity, water, insurance, rent, tuition, etc.—many of those will accept credit cards, but most will also allow ACH direct debit as a payment option and a few will only allow d

So it turns out that if you turn the volume all the way down to zero, it pauses playback. And if you turn it up again, it starts playing. I didn’t test whether navigation messages from Maps can still be heard. Not perfect as it takes a few

Thanks; I’ll double-check but I think pushing the volume button turns the whole infotainment system off. Which does pause whatever’s playing, but also turns off navigation or whatever else I had on the CarPlay screen.

Did the car you rented have a Play/Pause button on the steering wheel? That’s what I am missing the most: being able to quickly pause (and later resume) whatever I’m listening to through CarPlay because I need to pay attention to somet

Buying something for $100 using eBay’s credit card service does technically imply paying $100 to eBay, but eBay would not recognize $100 in revenue. eBay’s revenue from that transaction would only be the fees they collect, mainly the final

It would cause some practical difficulties if the corporation owned all its shares. For example, in the case of a Delaware corporation, shares owned by the corporation itself can’t vote, so it would not be possible to elect board members. S

I think they are implying that it could be fraud, but since there are birth certificates available, you couldn’t commit this fraud by simply making up a birth date. So a fraudulent supercentenarian would likely have assumed the identity of
