Update: Web Service Speed Improvements, Communist Ringo Learning, Dictionary Content Additions

I've been steadily updating, but it's been a while since I last wrote a post.

In the meantime, I've been deeply immersed in Soviet history and worked hard on the 'Communist Ringo' menu, adding a person dictionary, a term dictionary, and a historical events database.

It still needs to be reinforced going forward, but the materials are quite rich and I've put effort into the UI/UX, so please stop by the Communist Ringo dictionary.

As for the database, I was using Supabase SaaS, but the communication delay was frustrating (almost like traveling around the world), so I moved it to the local DB of the web server. Thanks to that, the page load speed of this site has improved a lot.

Also, when querying VectorDB, I was wasting 30 seconds on reranking with a local VM CPU, but by removing the reranking step, I reduced it to under 1 second, improving the chat service speed.

I've reverted the web chat AI model from DeepSeek v4 Flash to Pro, so the response quality is actually higher.
