A recent tweet highlighted the release of a new model called Diffusion LLM (dLLM) by Inception Labs. Unlike traditional autoregressive language models that generate text left to right, dLLMs generate words simultaneously for all parts of a sentence. This approach, which has been successful in image and video generation, is reportedly outperforming similar-sized LLMs in code generation. The author, who has spent two years in LLM evaluation, notes several advantages of dLLMs. Traditional L

The content discusses the concept of "distrust" regarding certification authorities (CAs) that issue HTTPS certificates. When a CA is removed from a root store due to a lack of trust, its certificates are invalidated, leading to potential browser errors for users. Distrust can arise from security issues, compliance failures, or general mistrust of the CA. Historically, the impact of distrust events varied based on the CA's size, but now, due to the requirement for public certificate transparency (CT

Michal Ganzarcik discusses the importance of maintaining quality standards in iterative development processes. He critiques the common practice of prioritizing quick implementations, often at the expense of thoroughness, by using a metaphor of a cow producing manure. While iterative methods can lead to progress, they can also result in poorly constructed outcomes if quality is neglected. Instead, he advocates for a focus on producing high-quality building blocks in each iteration, akin to constructing a palace. Consistent quality is necessary to create a robust and
