Tor is a powerful, open source network that enables anonymous and non-trackable (or difficult to track) browsing of the internet. It's able to achieve this because of users running Tor nodes, which serve as intentional detours between two otherwise direct paths. For instance, if you are in New Zealand and visit python.nz, instead of being routed next door to the data center running python.nz, your traffic might be routed to Pittsburgh and then Berlin and then Vanuatu and finally to python.nz. read more

So you want to learn to program? One of the most common languages to start with is Python, popular for its unique blend of object-oriented structure and simple syntax. Python is also an interpreted language, meaning you don't need to learn how to compile code into machine language: Python does that for you, allowing you to test your programs sometimes instantly and, in a way, while you write your code. read more

At PyBay 2019 in August, I will continue a conversation I started at PyBay 2018 about the importance of ethics in the artificial intelligence (AI) we're developing, especially as it gains more and more influence in our everyday lives. In last year's keynote, I dug into how we're overlooking the essential role humans play in AI's future. read more

With a focus on continuous improvements, agile project management upends the traditional linear way of developing products and services. Increasingly, organizations are adopting agile project management because it utilizes a series of shorter development cycles to deliver features and improve continually. This management style allows for rapid development, continuous integration (CI), and continuous delivery (CD). read more

Today's world—marked by an increase of Internet-connected devices, digital assets, and information systems infrastructure—demands more cybersecurity professionals. Cybersecurity is the practice of defending these devices, assets, and systems against malicious cyberattacks from both internal and external entities. Often these cyberattacks are linked to cybercrimes, or crimes committed using a computer to generate profit or to affect the integrity, availability, and confidentiality of the data or system. read more
