Facebook Introduces Physical Keys (FIDO U2F) as Security

Standard

Today, January 26, Facebook announced that they have introduced ‘physical keys’ (i.e. usb keys) as an option of the two-factor authentication. Google has already introduced this two years earlier.

A few years ago two-factor authentication was introduced by Google and Facebook among many other companies which allowed the user to set an extra security measure to avoid loosing their account in case their password was stolen. This extra layer required the user, if using a new computer or IP, to enter an authentication code generated (regularly) through an app (e.g. Google’s authenticator for Google accounts).

Check if you’ve had a security breach

Aside

Many of the popular websites and services have been or at some point or will be targetted and exploited. As a result, it is most likely that at least one of your online accounts has been pwned at some point. This doesn’t mean your account has been cracked but it could mean that some of your private information has been leaked (e.g. email, password, personal info like date of birth, etc…). Recently Gmail has been exploited by attachement phishing.

There’s no guaranteed way to check if your account has been hacked but one way is to check if you’ve been pwned. Just enter your username or email to check if you’ve been pwned.

Fluid Mechanics video lectures

Video

In a previous post we selected some resources on fluid dynamics. In that post we suggested the videos from the National Committe for Fluid Mechanics (notes on the website) that date to the 1960’s and is an excellent exposition to fluid mechanics. We share them below following a very clear demonstration of Euler’s equation and Bernoulli’s integral:

Sound of the Moving Earth

Audio

What do you think an earthquake would sound like if you could hear it?

Here’s a sample (opens in a new tab).

The audio was generate by processing seismic data.

More samples are available on from the source where you can also find the corresponding spectrograms, (i.e. the representation of the frequency content of the signal and how it varies in time).

Every Classroom Should Have This Infographic

Standard

Mindset: The New Psychology of Success by Dr. Carol Dweck is a must read for every parent, teacher and student. As a matter of fact, it should be read by everyone.

Parents and teachers should stop labeling students as “smart” or “dumb” or as “good” or “bad”. Instead they should be taught that everyone is capable of anything one puts his or her mind to.

Moreover, I think the two mindsets should explained to every student and the infographic be hanged in every classroom and house everywhere as a reminder of the two mindsets. Maybe also assign the book for reading as part of the reading list? Continue reading
