Most people aren’t aware that their car is a high-tech computer. You could say that modern cars are smart phones on wheels.
In this episode of “Phreaked Out,” we met some of the top security researchers at the center of the car hacking world. The goal isn’t to make people crash: They highlight security holes in order to highlight flaws in car technology, intended to pressure auto manufacturers to be a few steps ahead of their friendly foes.
Information security researcher Mathew Solnik gave us a first-hand demonstration on how to wirelessly send commands to the car and remotely tell it what to do. With a little over a grand and about a month of work, Solnik found time outside of his full-time job to reverse-engineer a car’s computer system to make it ready for a takeover.
From his laptop, he was able to manipulate the car’s engine, brakes and security systems by wirelessly tapping into the Controller Area Network, or CAN bus, network. Without getting too deep into the details—both for legal reasons and due to my own training-wheel knowledge of such things—he was able to do so by implementing some off-the-shelf chips, a third party telematic control unit, a GSM-powered wireless transmitter/receiver setup, and a significant amount of know-how he’s accrued over the years.
The reason for such additional hardware was to make our older, mid-sized sedan function like a newer—and arguably more vulnerable—stock vehicle, which these days often come with data connections. (We would have loved to tinker with the latest, most connected car on the market, but since we were on a shoestring budget and it’s incredibly hard to find a friend who’s willing to lend their car for a hacking experiment, our pickings were slim.)
With that said, a car whose network system is connected to a cloud server and accessible by Bluetooth, cell networks, or wi-fi is potentially vulnerable to intrusion.
Today we learn how to read music.
Enjoy!
Like an actor’s script, a sheet of music instructs a musician on what to play (the pitch) and when to play it (the rhythm). Sheet music may look complicated, but once you’ve gotten the hang of a few simple elements like notes, bars and clefs, you’re ready to rock. Tim Hansen hits the instrumental basics you need to read music.
This recipe from Bismarck, North Dakota bakery, Luz’s Unique Creations:
First you find some nice and bright colored bananas with hardly any bruising on them. Then you wash them under water and dry them gently. Use a sharp knife and cut the stem all the way to the banana and a little past to make a smile and to be able to open them to put a grape into the opening.
Handimania created this video that demonstrates how to draw a hand in 3D.
Today we are so excited to show you our video tutorial for 3D Handprint optical illusion! No matter if your kids are pre-writers or writers, this mesmerizing 3D Handprint optical illusion is great in practicing manual skills and so fun at the same time.
Hope this will inspire you to make a lot of these drawings with your little ones! We’ll be more than happy to see the results of your work, so don’t be shy and share them with us and other handimaniacs.
