Devices, apps, robots, and everything else that makes technology essential to your modern life.



Staying secure in the modern world is more difficult than ever. Every day, we face threats to our identities, our personal information, our data, and even ourselves. From malware attacks to phishing schemes, we survey the security landscape. It takes a lot more than some anti-virus software to stay safe. We go beyond the sensationalism to assess which threats could pose the biggest problems and dig into the repercussions that ripple through our lives once security has been compromised. KEEP GOING


Sure, artificial intelligence can generate hilarious song titles and paint colors, but it’s also powering some of the most compelling new technology of our time. Machine learning and neural networks are playing larger roles in almost every device and system we use. It’s built into your smartphone, your smart home, and maybe

Computer Science Lab Home Page: Learn Computer Programming

Joaquina Erdmann

This unique computer curriculum offers 3 different environments of graduated
complexity: a programmable RPN (Reverse Polish Notation) calculator, an Intel
8051 microprocessor that is programmed using assembly language, and finally the
high-level C and C++ languages.

Each of these 3 languages comes complete with an
integrated development environment
(IDE) that provides an editor, compiler, and debugger. You
get fully explained solutions to fun programming projects such as
a scrolling electronic signboard, a robotic mouse in a maze, an audio
peak detector using an LED bar graph, and the Breakout video game.
All of these example programs have been designed to be highly visual,
audible, and fun.
In addition to the introduction to assembly language programming and
the introduction to C and C++, this curriculum offers an introduction to
Windows programming and graphical user interfaces.
You can find screen shots and further description of each of

Virtual Talk: Topology-Driven Machine Learning – Chao Chen

Virtual Talk: Topology-Driven Machine Learning – Chao Chen via Zoom
Abstract: Modern machine learning is blessed and cursed with highly complex models. While deep neural networks have proven powerful in practice, their deployment in real-world applications faces challenges such as explanability and robustness. One crucial reason is the lack of sufficient means to track/control the underlying structure of the model/data. In this talk, we present examples in which advanced structural prior can be encoded into learning through the mathematical language of topology. We will explain how global topological structures, such as connected components and handles/loops, can be efficiently and robustly extracted from the data, as advanced features and even differentiable loss functions. In biomedical applications, e.g., neuron and cell image analysis, we proposed a novel topological loss function that enforces the neural network to learn the topology from the data. In machine
