Sending strings between two computers via ethernet
A while ago I asked a question about using RS-232 communication with Java. It seems as though I need to abandon that route because it no longer fits the desired system requirements. Thanks to Nem for his advice on that one.
Now what I need to be able to do is send and receive strings between two computers connected via a network hub. The computers in use would not be connected to the outside world and would only be communicating with each other at this point.
I need to be able to send a string like "auto" terminated with a carriage return when a button on a GUI is pressed by the user. The GUI would then need to get back a string like "ok" or "err" also followed by a carriage return.
I am sure that I am making this much harder than I need to, so if anyone can help out it would appreciated. For some reason I am having a lot of trouble absorbing how to use Java, so any help or explanations need to be in beginner terms.
Thanks.

Google Researchers Propose Bayesian Teaching Method for Large Language Models
Google Research has proposed a training method that teaches large language models to approximate Bayesian reasoning by learning from the predictions of an optimal Bayesian system. The approach focuses on improving how models update beliefs as they receive new information during multi-step interactions.

Cloudflare recently announced support for ASPA (Autonomous System Provider Authorization). The new cryptographic standard helps make Internet routing safer by verifying the path data takes across networks to reach its destination and preventing traffic from traversing unreliable or untrusted networks.

DoorDash engineers built a simulation and evaluation flywheel to test large language model customer support chatbots at scale. The system generates multi-turn synthetic conversations using historical transcripts and backend mocks, evaluates outcomes with an LLM-as-judge framework, and enables rapid iteration on prompts, context, and system design before production deployment.
