Eventually, in my final stage of praise withdrawal, I realized that not telling my son he was smart meant I was leaving it up to him to make his own conclusion about his intelligence.

Hackers Could Make a Killing After Finding Vulnerability in Medical Device Tech Maybe this is the shakeup we need, so businesses start taking security seriously:

After finding serious security vulnerabilities in St. Jude Medical’s pacemakers and defibrillators, cybersecurity and research company MedSec decided to take that information to a short-seller (Carson Block of the investment firm Muddy Waters) which then bet against the company in the stock market.

MedSec’s CEO Justine Bone says that her company didn’t disclose to St. Jude because it was unconvinced the medical device maker would actually fix the problem. Rather than have the problem ignored (and potentially put patient’s lives at risk), MedSec decided to not just shame St. Jude, but make it pay.
