March 25, 2024 in Database

Redis "going non-open source" is not a disgrace to Redis, but a disgrace to "open source/OSI" and even more so to public cloud. What truly matters has always been software freedom, while open source is just one means to achieve software freedom.

November 21, 2023 in Database

Vector storage and retrieval is a real need, but specialized vector databases are already dead. Small needs are solved by OpenAI directly, standard needs are captured by existing mature databases with vector extensions. The ecological niche left for specialized vector databases might support one company, but trying to build an industry around AI stories is impossible.

Are Databases Really Being Strangled?
November 02, 2023 in Database

Many "domestic databases" are just shoddy, inferior products that can't be helped. Xinchuang domestic OS/databases are essentially **IT pre-made meals in schools**. Users hold their noses while migrating, developers pretend to work hard, and everyone plays along with leaders who neither understand nor care about technology. The infrastructure software industry isn't being strangled by anyone - the real chokehold comes from the so-called "insiders."

What Kind of Self-Reliance Do Infrastructure Software Need?
August 31, 2023 in Database

When we talk about self-reliance and control, what are we really talking about? Operational self-reliance vs. R&D self-reliance - what nations/users truly need is the former, not flashy "self-research".
