Jina AI Launches First Open-Source 8K Text Embedding, Rivaling OpenAI
Summary: Jina AI has launched the world's first open-source 8K text embedding model, jina-embeddings-v2, rivaling OpenAI's proprietary model in capabilities and performance. The model supports an 8K context length, enabling applications in legal document analysis, medical research, literary analysis, financial forecasting, and conversational AI. Jina AI offers two versions: a base model for heavy-duty tasks and a small model for lightweight applications. The company plans to publish an academic paper, develop an embeddings API platform, and expand into multilingual embeddings.

Running the "Reflections on Trusting Trust" Compiler
Summary: In October 1983, Ken Thompson discussed supply chain security in his Turing award lecture, "Reflections on Trusting Trust." He explained how to modify a C compiler binary to insert a backdoor when compiling the "login" program, leaving no trace in the source code. In this post, the author runs the backdoored compiler using Ken's actual code. The author also demonstrates a modern variant of the backdoor using the Go compiler. The post highlights the importance of supply chain security and the potential risks of backdoors in software.
