1. How video games use lookup tables Total comment counts : 20 Summary This article discusses the use of look-up-tables (LUTs) in graphics programming, using WebGL as an example. LUTs allow for creative techniques in manipulating video footage, such as turning grayscale footage into color or creating variations of images. The article explains the use of LUTs in the fragment shader, where each pixel’s final color is determined. The article also mentions the performance implications of using LUTs and provides examples of how they have been used in games like Left 4 Dead....

1. GenAI and erroneous medical references Total comment counts : 23 Summary Large language models (LLMs) like ChatGPT are being used in the medical field, but there are concerns about their safety and effectiveness. The U.S. Food and Drug Administration (FDA) is struggling to regulate these models since they fall in a gray area between existing technologies. The FDA has approved over 700 AI medical devices, but LLMs pose a challenge because they combine existing medical information with potential ideas that may not be accurate....

1. GPT in 500 Lines of SQL Total comment counts : 23 Summary The article discusses implementing a large language model in SQL. The author explains that a generative language model takes a text string as input and returns an array of strings and numbers. The model predicts the probability of the next word based on the input. The article also provides an overview of large language models and how they are used in various text applications....
