Cython is a compiler for the Python programming language meant to optimize performance and form an extended Cython programming language. As an extension of Python, Cython is also a superset of the Python language, and it supports calling C functions and declaring C types on variables and class attributes. This makes it easy to wrap external C libraries, embed C into existing applications, or write C extensions for Python in syntax as easy as Python itself.

When I go on holiday, I often end up at one or more used bookstores. I always find a good book I've been meaning to read, and I always justify the inevitable purchase by saying, "I'm on vacation; I should treat myself to this book." It works well, and I've acquired some of my favorite books this way. Yet, like so many traditions in life, it doesn't hold up to scrutiny. In reality, I don't need an excuse to buy a good book. All things being equal, I can do it any time I want. But having a reason does seem to make the process more enjoyable, somehow.

Users have every right to be concerned about the safety and security of their data. When you create data on a computer, it's reasonable to want exclusive control over it. There are many ways to protect your documents. At the filesystem level, you can encrypt your hard drive or just a file. A good office suite affords you many more options, though, and I've gathered five of the methods I use to secure my documents with open source software. read more

Most people connect to at least two networks every day. After you turn on a computer or mobile device, it connects to a local WiFi network, which in turn provides access to the interconnected network of networks that is "the internet" (a combination of the words interconnected networks). But how do networks actually work? How does your device know how to find the internet, a shared printer, or a file share? How do these things know how to respond to your device? What tricks do system administrators use to optimize the performance of a network? read more
