There's a moment in almost every RAG project where someone asks the question that decides your next two years of ops work: "Do we actually need a vector database, or can Postgres just do this?" It's a better question than it sounds, because the honest answer isn't "use Pinecone" or "use Postgres." It's "it depends on numbers you probably haven't measured yet": how many vectors, how aggressively you filter, how much you care about the absolute ceiling of queries per second. Most teams pick bas... Read more ›

I am learning about the Data eco-system and keep hearing about Icerberg as the open table format. However, I haven't come across anyone so far thats using it. Curious, if you see, what do you use it for? Read more ›
The LCD7-PANEL-LIME2 is a ready-to-mount Linux touch panel computer from Olimex, based on the company’s A20-OLinuXino-LIME2 open hardware SBC. The unit combines a 7-inch capacitive touchscreen, a plastic panel-mount frame, mounting brackets, ribbon cable, and an assembled A20-based Linux board into a single package. The computer board is the A20-OLinuXino-LIME2-e16Gs16M, an open-source ARM Linux SBC built around the Allwinner A20… Read more ›

One AI agent answering a question is useful. Five agents that divide a complex task, pass state to each other, and act on live enterprise systems is a meaningfully different category of system. It also carries a meaningfully different category of operational problems. Multi-agent orchestration is the architectural pattern that makes the second case coherent. But a lot of teams prototype multi-agent systems in a weekend and then spend months figuring out why production is unpredictable, expens... Read more ›

In the previous post we walked through WasmForge, our Go-to-WebAssembly loader that takes existing signatured Go tools and ships them as opsec-safe binaries. This approach doesn’t just apply to Go, however, as there are many languages that can compile to WebAssembly. Another language of interest to us, especially regarding legacy tools which have been over-signatured, […] The post appeared first on <a href=" Read more ›
A grounded walk through Lume's retrieval core - field-aware BM25, two-stage roaring/Godel pruning, local GTR-T5 vectors via Shivvr, a significance-scored entity graph, the multiplicative blend that fuses them, and the knobs that tune it all. Read more ›
Learned sparse retrieval (LSR) models such as SPLADE have traditionally used BERT-style masked language models as backbone encoders. A natural expectation is that replacing BERT with stronger pretrained encoders should improve retrieval effectiveness. However, we find that under standard SPLADE training recipes, backbones with large MLM-head L2 norms can suffer performance degradation and even training collapse under standard SPLADE training rec...

If you have a massive compute architecture—whether it’s a modern wide-SIMD vector engine, a Tensor Core array, or a custom deep learning accelerator like a Systolic Array—you face one fundamental problem: feeding the beast. You have immense execution width, but if your instructions are bottlenecked by branch overhead and short basic blocks, those execution units sit idle. Read more ›
