linked list Friday: how long do vaccines last?, the blockchain bandit, climate change quiz
How long do vaccines last? The surprising answers may help protect people longer – The “surprising answer” is “for some vaccines, not that long!”. Apparently for the flu shot your immunity can vanish as soon as three months after you get the vaccine, which means if you get it in September it might be gone by January, which is around the peak of flu season. So I think we’re going to start getting our flu shots a bit later! (thanks David!)
A ‘Blockchain Bandit’ Is Guessing Private Keys and Scoring Millions – ah, cryptocurrency. Here’s another take on this. While this particular problem seems unlikely to hit average users (I guess? why the extremely weak private keys were chosen is still not really known), this is a good example of why you probably shouldn’t be using cryptocurrency unless you know what you’re doing, and even if you are you’re still vulnerable to shady operators like Bitfinex.
