Foundations of Computer Vision

Foundations of Computer Vision Preface Dedicated to all the pixels. About this Book This book covers foundational topics within computer vision, with an image processing and machine learning perspective. We want to build the reader’s intuition and so we include many visualizations. The audience is undergraduate and graduate students who are entering the field, but we hope experienced practitioners will find the book valuable as well. Our initial goal was to write a large book that provided a g

What Is Raspberry Pi and How Can I Use It for My Home Internet?

A Raspberry Pi computer can do a little of everything, including keeping you occupied if you need a new project (or distraction). This teeny-tiny computer not only clocks in at a low price, but could potentially help you trim costs by becoming a DIY router. Saving money is appealing: A recent CNET survey showed that internet costs spiked for 63% of US adults last year. When our budgets are tight, having a device that can cover the gamut is appealing, from hosting your home internet to providing

Cray versus Raspberry Pi

Please visit the sponsor! Cray versus Raspberry Pi I fondly recall the era when the pinnacle of supercomputing was the Cray 1. Even the shape of this computer was massively different to anything that came before and it was so futuristic that it could have come straight from a scifi movie. While almost all other computers of the 1970s were just a collection of huge rectangular cabinets with blinky lights and perhaps a few tape drives, the Cray 1 looked more like a piece of space-age furnitu

The Missing Manual for Signals: State Management for Python Developers

A practical guide to reactive state management in Python Introduction I maintain reaktiv. When I demo it to Python teams, I get the same response: "Why do I need this? I can just call functions when things change." Fair question. Python has excellent patterns for coordinating state changes. You can trigger updates manually, use the observer pattern, or set up event systems. Most Python applications handle state coordination just fine. But some don't. If you're building systems where state c

Nvidia CEO says quantum computing is reaching an 'inflection point'

Nvidia CEO Jensen Huang is growing more bullish about quantum computing — and he expects they'll start solving real-world problems in the coming years. "Quantum computing is reaching an inflection point," Jensen declared during his keynote speech at Nvidia's GTC Paris developer conference Wednesday. Quantum computers are machines that use the laws of quantum mechanics to solve problems too complex for classical computers, which store information in bits (ones and zeroes). Quantum computers us

The Download: IBM’s quantum computer, and cuts to military AI testing

The news: IBM announced detailed plans today to build an error-corrected quantum computer with significantly more computational capability than existing machines by 2028. It hopes to make the computer available to users via the cloud by 2029. What is it? The proposed machine, named Starling, will consist of a network of modules, each of which contains a set of chips, housed within a new data center in Poughkeepsie, New York. Why it matters: IBM claims Starling will be a leap forward in qua

With iPadOS 26, Apple has finally turned the iPad into a computer

With the announcement of iPadOS 26, Apple has finally done something it had seemed to be resisting for well over a decade: turning the iPad into a computer. Apple has long sent mixed messages about the device, sometimes arguing that it is a computer, and other times arguing that iPads and Macs are two very different devices with two very different roles … The iPad was not a computer On the one hand, as far back as 2017 Apple ran the What’s a computer? ad campaign, essentially arguing that the

The Seymour Cray Era of Supercomputers

The Seymour Cray Era of Supercomputers (Review) 2025-06-11 The Seymour Cray Era of Supercomputers: From Fast Machines to Fast Codes is a technical and business history of the roughly three-decades when Seymour Cray dominated the development of a class of computer called the “supercomputer”. The book covers the development of the major supercomputer models, the technical decisions and trade-offs involved, and changes to the market. The book ends with SGI’s purchase of Cray’s assets and the tran

Will quantum computers disrupt critical infrastructure?

Will quantum computers disrupt critical infrastructure? 3 hours ago Joe Fay Technology Reporter Google Many organisations are developing quantum computers Twenty five years ago computer programmers were racing to fix the millennium bug amidst fears that it would cause banking systems to crash and planes to fall out of the sky. Much to everyone's relief the impact turned out to be minimal. Today, some fear there is a new critical threat to the world’s digital infrastructure. But this time, we

The Download: Microsoft’s quantum chip, and explaining rising energy demand

A new Microsoft chip could lead to more stable quantum computers Microsoft has announced that it’s made significant progress in its 20-year quest to make topological quantum bits, or qubits—a special approach to building quantum computers that could make them more stable and easier to scale up. The company says it’s developed a chip containing eight of these qubits, and has also published a Nature paper that describes a fundamental validation of the system. It’s a different approach to competi
