Fonts are often a mystery to many computer users. For example, have you designed a cool flyer and, when you take the file somewhere for printing, find all the titles rendered in Arial because the printer doesn't have the fancy font you used in your design? There are ways to prevent this, of course: you can convert words in special fonts into paths, bundle fonts into a PDF, bundle open source fonts with your design files, or—at least—list the fonts required. And yet it's still a problem because we're human and we're forgetful. read more

The first Open Networking Summit was held in October 2011 at Stanford University and described as a premier event about OpenFlow and Software-Defined Networking (SDN)". Here we are seven and half years later and I'm constantly amazed at both how far we've come since then, and at how quickly a traditionally slow-moving industry like telecommunications is embracing change and innovation powered by open source.

PyTorch is a Python based scientific package which provides a replacement of NumPy ndarrays as Tensors which takes utmost advantage of the GPUs. Another positive point about PyTorch framework is the speed and flexibility it provides during computing. PyTorch is an efficient alternative of working with Tensors. PyTorch is mainly embraced by the Data Science community due to its capability to conveniently define neural networks. Let’s see this computational package in action in this lesson.
