A vector database stores data as vectors (embeddings) and finds items by meaning, not exact match. What it is, how similarity search works, how it differs from a normal database, and why RAG and AI search depend on it. Read more ›
AI makes us faster, but does it make us better engineers, or just more dependent? As a follow-up to my post on the , I wanted to created a quiz as a self-assessment for AI-assisted development habits. My previous post sparked many interesting discussions and insights. I took some of those elements and put together a series of questions to help evaluate how you are using AI as a developer. The 4 Archetypes include: AI Architect: owns the problem, uses AI as leverage AI Balancer: productive wit... 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...

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 ›
You start with one AI agent to save time. A month later, you've got prompts in a doc, outputs in Slack, half-finished automations in three places, and the same request getting handled a dozen different ways depending on who saw it first. That's what happens when businesses try to "do AI" by building roughly 43 agents with no plan in place to coordinate them. AI agent orchestration solves this problem. Instead of relying on a single, general-purpose AI agent to do everything (which rarely works), Read more ›

The lines between transactional systems, analytical systems, hybrid systems, and shared storage architectures are getting blurry. This post proposes a small taxonomy for describing the different ways systems, workloads, storage tiers, visibility, and durable copies relate to each other. OLTP, OLAP, HTAP, and now LTAP. We can think of the first two as two types of workload which have specialized query engines and storage systems to support them. OLTP such as the RDBMS like Postgres and MySQL u... Read more ›

💡 What is vSAN OSA & ESA? VMware vSAN Original Storage Architecture (OSA) is the legacy disk-group-based architecture designed for mixed magnetic/SSD environments. The newer Express Storage Architecture (ESA) is optimized entirely for high-performance NVMe drives, eliminating disk groups in favor of a single Storage Pool. Enterprise architecture often requires running highly divergent workloads on shared physical infrastructure. Balancing the deterministic latency needed for transactional pro... Read more ›
Less than a year ago, PCIe 6.0 in a normal PC sounded about as realistic as a silent high-end system without five kilograms of heatsinks. At the time, Silicon Motion spoke of an introduction toward the end of the decade. Now the company suddenly names the end of 2027 as the target for its first […] Read more ›

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 ›
