Germans warned to DESTROY Cayla, network-connected doll that spies on children

It’s called Cayla , it’s about a foot tall, and it can be used to listen to and talk to the child playing with it. But who is doing the listening? Anyone in Bluetooth range, reports Germany’s Federal Network Agency (Bundesnetzagentur). An official watchdog in Germany has told parents to destroy a talking doll called Cayla because its smart technology can reveal personal data. … The Vivid Toy group, which distributes My Friend Cayla, has previously said that examples of hacking were isolated and carried out by specialists. However, it said the company would take the information on board as it was able to upgrade the app used with the doll. But experts have warned that the problem has not been fixed. The Cayla doll can respond to a user’s question by accessing the internet. For example, if a child asks the doll “what is a little horse called?” the doll can reply “it’s called a foal”. Watch the BBC’s video of Cayla, in its squeaky, sinister voice, say “I’ve been hacked to say all sorts of scary things.” https://www.youtube.com/watch?v=U0Y2KUN6XPM Cayla was on Boing Boing last year when the FCC received complaints about it. Cayla is on Amazon for $45 . It’s so easy to hack that everyday YouTubers are at it! https://www.youtube.com/watch?v=EvMb_TusPPs

The world’s littlest laptop is yours for $399, but is it the ultimate writers’ gadget?

The GPD Pocket is a wee laptop with a 7″ high-dpi touchscreen display and an enticing $399 price tag. It’ll be light on power, with an Intel Atom CPU, 8GB of RAM and a 128GB SSD, but promises about 12 hours on a charge and two USB ports, one of them type C. There’s a ThinkBook-style tracknipple in lieu of a trackpad. It’ll run Ubuntu or Windows 10 and, somehow, they managed to sneak a headphone jack on there. (more…)

The story of Indian mathematical genius Srinivasa Ramanujan

In 1913, English mathematician G.H. Hardy received a package from an unknown accounting clerk in India, with nine pages of mathematical results that he found “scarcely possible to believe.” In this week’s episode of the Futility Closet podcast, we’ll follow the unlikely friendship that sprang up between Hardy and Srinivasa Ramanujan, whom Hardy called “the most romantic figure in the recent history of mathematics.” We’ll also probe Carson McCullers’ heart and puzzle over a well-proportioned amputee.

How "I’m not a Robot" checkboxes work

Zuck That says, “Have you ever been on the Internet when you came across a checkbox that says “I’m not a robot?” In this video, I explain how those checkboxes (No CAPTCHA reCAPTCHAs) work as well as why they exist in the first place.” I mention CAPTCHA farms briefly, but the idea behind them is pretty straightforward. If a company wants to create an automatic computer program to buy 1,000 tickets to an event or make 1,000 email accounts, they can make a script that fills out the form one at a time, and when the program gets to a CAPTCHA, it will send a picture of it to a CAPTCHA farm where a low-wage worker will solve it and send the answer back to the computer program so that it can be used to finish filling out the form.

Unprecedented: Japan’s population has declined by 1 million in 5 years

Rich countries have low birthrates (in part because they have more rights for women, and women who can control their bodies and fates choose to have fewer children on average than women who live in poor countries with fewer rights for women); Japan, one of the most xenophobic of all the rich countries, has the killer combination of a near-total ban on immigration from poor countries (where all the young people are) and a high standard of living.
