Title: New Trends and Discussions in Crypto and AI: Dogecoin20's Success and the Future of RAG

In a surprising turn of events in the cryptocurrency world, the new meme coin 'Dogecoin20' (DOGE20) successfully raised over $10 million during its late March crypto presale, meeting its target funds ahead of its anticipated DOGE Day launch. This development not only highlights the continuing popularity of meme-based cryptocurrencies but also sets the stage for future projects inspired by Dogecoin's success.

In the realm of technology and AI, discussions about long context windows and their impact on retrieval-augmented generation (RAG) technologies have come to the forefront. With insights from experts Michael Foree of Stack Overflow and Cassidy Williams of Contenda, there's a deep dive into how advancements in these areas could redefine the capabilities and limitations of RAG, particularly with the support of platforms like Databricks.

Additionally, the spotlight turns to the regulatory landscape, as the U.S. Securities and Exchange Commission (SEC) takes a firm stance against 'AI Washing'—a practice where companies overstate or fabricate their use of artificial intelligence to attract investment. This move, championed by CryptoWhistleBlower's founder Daren Firestone, is a critical step towards protecting investors and maintaining integrity within the rapidly evolving sectors of machine learning and cryptocurrency.
