Diffusion models are gaining popularity in generative modeling, showing exceptional results in sampling from multimodal distributions. They are widely used in text-to-image tools like Stable Diffusion and other domains like audio, video, protein design, and robotics. This tutorial focuses on implementing diffusion models from scratch using optimization theory. By training neural networks to predict noise […]

Cosine-similarity is used to measure semantic similarity by comparing vectors, but it may not always give accurate results compared to unnormalized dot-products. Regularized linear models can provide insights into why cosine-similarity may not always be reliable, as it can lead to arbitrary and meaningless similarities. The regularization used in learning deep models can also have […]
The Wikipedia page discusses Simpson’s Paradox, showing how a positive trend can appear in separate groups, only to reverse when combined. This phenomenon is commonly seen in social science and medical statistics, highlighting the risks of misjudging causal relationships. Notably, the page includes examples like gender bias in UC Berkeley admissions and kidney stone treatments […]
The author introduces the JSON Canvas format as a way to store infinite canvas data, which allows for spatially organizing information like a digital whiteboard. This format aims to provide longevity, readability, interoperability, and extensibility to data created with infinite canvas apps. JSON Canvas files use the .canvas extension and can be freely implemented in […]
Estimating Software Projects: The author shares insights on breaking down tasks for software projects, emphasizing the importance of clearly defining work that delivers change. Through examples of building a personal streak tracker, the process of breaking down tasks into smaller steps is demonstrated. The author explains the iterative process of adding detail to tasks, ensuring […]
Webb measurements from NASA/ESA/CSA have resolved the Hubble Tension about the Universe’s expansion rate, confirming Hubble’s accuracy. Despite some discrepancies with other observations, Webb’s validation supports the idea that there is more to understand about the Universe. Some speculate that unseen errors may emerge as we delve deeper into space, but recent observations with Webb […]
The summer of 2007 was marked by Apple’s release of the iPhone, causing mixed reactions. In Canada, the iPhone was not initially available, but hope came through the iPhone Dev Team, aiming to enable the device to run with any carrier using software alone. The Dev Team provided updates on their progress via their blog, […]

The authors welcome feedback on typos and comments to improve the book. They acknowledge the valuable input from contributors and promise an updated full book draft with fixes. […]
Since the initial release in 2014, the Speedometer benchmark has become essential for browser engines to enhance performance. The latest version, Speedometer 3.0, is a collaborative effort between Blink, Gecko, and WebKit. This release marks a significant advancement in web browser performance testing by introducing a more accurate way of measuring performance and a broader […]
This page details how to implement computer language interpreters and specifically constructs an interpreter for a Scheme dialect of Lisp using Python. The author showcases the simplicity and consistency of Scheme syntax compared to other programming languages like Java and Python. The article covers the syntax and semantics of Scheme programs, introduces a simplified Lispy […]
