Image Kernels Explained Visually
An image kernel is a small matrix used to apply effects like the ones you might find in Photoshop or Gimp, such as blurring, sharpening, outlining or embossing. They're also used in machine learning for 'feature extraction', a technique for determining the most important portions of an image. In this context the process is referred to more generally as "convolution" (see: convolutional neural networks.)

Timing attack on arduino
I like Side Channels Attacks. It's a way to gather some information about your target (software, hardware device, web site) by a way (the channel) not directly related with the primary task of your target. These channels are unintentional consequences, or artifact, of the primary task.
