T-SQL on Microsoft Fabric - Episode 1: Mastering Data Retrieval with SELECT, WHERE, and ORDER BY Learning Goals In this lesson, you will learn how to: Read data from tables using SELECT Filter rows with WHERE Sort query results with ORDER BY Get familiar with standard T-SQL syntax Practice directly in Microsoft Fabric Warehouse 1. Understanding Database and Schema In Fabric Warehouse, objects are commonly organized like this: Warehouse | |-- sales | |-- Customers | |-- Orders | |-- hr | |-- Employees | |-- finance |-- Transactions Schemas help you: Group related tables Manage permissions Organize large systems more effectively 2. Create a Schema Create a schema for the sales dataset: CREATE SCHEMA sales ; Check existing schemas: SELECT * FROM sys . schemas ; 3. Create Tables Create the Customers table: CREATE TABLE sales . Customers ( CustomerID INT , CustomerName VARCHAR ( 100 ), City VARCHAR ( 50 ), Country VARCHAR ( 50 ) ); Create the Orders table: CREATE TABLE sales . Orders ( OrderID INT , CustomerID INT , OrderDate DATE , Amount DECIMAL ( 10 , 2 ) ); 4. Insert Sample Data Customers INSERT INTO sales . Customers VALUES ( 1 , 'John Smith' , 'New York' , 'USA' ), ( 2 , 'Emma Brown' , 'Chicago' , 'USA' ), ( 3 , 'David Wilson' , 'London' , 'UK' ), ( 4 , 'Sophia Taylor' , 'Manchester' , 'UK' ), ( 5 , 'Michael Lee' , 'Singapore' , 'Singapore' ); Orders INSERT INTO sales . Orders VALUES ( 101 , 1 , '2026-01-10' , 1200 . 00 ), ( 102 , 1 , '2026-01-15' , 800 . 00 ), ( 103 , 2 , '2026-01-20' , 2500 . 00 ), ( 104 , 3 , '2026-02-01' , 500 . 00 ), ( 105 , 5 , '2026-02-05' , 3200 . 00 ); 5. SELECT Get all columns: SELECT * FROM sales . Customers ; Get specific columns: SELECT CustomerName , Country FROM sales . Customers ; 6. Alias Rename columns in the output: SELECT CustomerName AS Customer , Country AS Nation FROM sales . Customers ; 7. WHERE Filter rows using conditions. Customers in the USA: SELECT * FROM sales . Customers WHERE Country = 'USA' ; Orders greater than 100

This article was originally published on aifoss.dev --- title: 'Chroma vs Qdrant vs Weaviate 2026: RAG Database Compared' description: 'Compare Chroma, Qdrant, and Weaviate for local RAG in 2026: version snapshots, filtering tradeoffs, hybrid search, quantization, and a clear pick by use case.' pubDate: 'May 27 2026' tags: ["vectordb", "ai", "rag", "python", "opensource"] The three most commonly recommended open-source vector databases for RAG — Chroma, Qdrant, and Weaviate — are not interchangeable. Chroma is a prototyping tool that grew into a real product. Qdrant is a production workhorse written in Rust with the best filtering performance of the three. Weaviate is an enterprise-grade platform with hybrid search and the most built-in integrations. Using Weaviate when you need Chroma adds unnecessary ops overhead. Using Chroma when you need Qdrant means migrating under pressure when your collection outgrows it. Versions covered: ChromaDB v1.5.9 (May 2026), Qdrant v1.17.1 (March 2026), Weaviate v1.37 (May 2026). The quick answer Situation Best choice Local prototyping, notebooks, under 100K vectors Chroma Embedded in a Python process — no separate service Chroma Production RAG with filtering-heavy queries Qdrant Multi-user deployment, concurrent queries Qdrant Memory-constrained deployment at millions of vectors Qdrant Hybrid search (BM25 + vector in one query) Weaviate Multi-modal retrieval (text + images + audio) Weaviate Built-in re-ranking or generative AI modules Weaviate Kubernetes, team-operated, agentic MCP workflows Weaviate Getting from zero to working RAG in 10 minutes Chroma What each tool actually is ChromaDB (Apache 2.0, chroma-core/chroma ) started as a pure-Python embedded database and was rebuilt in Rust for the v1.0 release. The Rust core eliminates Python's GIL bottlenecks and delivers roughly 4× faster writes and queries compared to the pre-1.0 implementation — write throughput went from ~10K to ~40K+ vectors/second in server mode. Chroma's des

A homelab box that never sleeps runs 8,760 hours a year. So the spec that decides what it costs you is not the one on the box. It is the one nobody prints: how many watts it pulls sitting at the login prompt doing nothing. I kept hitting this while shopping for a Proxmox node, so I put the measured numbers in one place. More on that at the end. First, why the spec sheet lies to you. TDP is a thermal budget, not a power reading TDP is the heat the cooler has to handle at full tilt. It is a design target for the heatsink, not a measurement of what the chip draws, and it says almost nothing about idle. Your homelab box spends 95%+ of its life idle, so the number that runs up the meter is idle wall power, and that number is never on the product page. The arithmetic is unforgiving. One watt running continuously is 8.76 kWh a year. So the gap between a 7 W box and a 35 W box is not 28 watts, it is about 245 kWh a year, every year, for as long as the box is on. Plug in your own rate to get the dollars; the point is the gap compounds. Where TDP actively misleads you A few measured results from the dataset I'll link below, all from third-party wall-meter readings, not vendor claims: The new N100 wave is genuinely low. A Minisforum UN100C measures 5 to 7 W at idle. Beelink, GMKtec and Trigkey N100 boxes land in the 6 to 10 W range. For a Pi-hole, a few containers and some light VMs, this tier is hard to beat on running cost. AMD mini PCs idle far higher than their marketing suggests. A Minisforum UM790 Pro measures 25 to 45 W at idle. A Beelink SER6 Pro lands at 20 to 35 W. These are fast little machines, but if you picked one expecting "small box, small draw," the meter disagrees, and over a year that delta is real money. Newer and higher-TDP is not lower-idle. A Dell OptiPlex 7060 Micro idles just over 18 W on its 65 W-TDP desktop chip. The older 7070 with a six-core part sits around 13 W, and the low-power "T" SKUs lower still. The CPU's TDP class predicted idle better tha

Predictions are scored quarterly against stated falsifiers. PREDICTION-20260601-0008 Created: 2026-06-01 Pattern: boredom-with-asymmetric-leverage Substrate: Open-source package registries (npm, PyPI, Crates.io, Packagist) and GitHub Actions CI/CD workflow injection Leading indicator observed: Four distinct, concurrent, cross-registry supply chain campaigns (TrapDoor: 34 packages across npm/PyPI/Crates.io; Megalodon: 5,718 automated commits to 5,561 GitHub repos in six hours; Packagist compromise of 8 packages; Laravel-Lang PHP credential stealer) appeared within a 72-hour window in 2026-W22, all exhibiting automation signatures — throwaway publisher accounts, wave publishing, base64-encoded shell payloads, off-the-shelf delivery via GitHub Releases — consistent with toolkit operation rather than bespoke tradecraft. npm's reactive rollout of 2FA-gated publishing signals registry operators recognizing volume pressure. Predicted window: 2026-Q3 through 2027-Q1 Predicted shape: Automated, low-sophistication credential-stealing and backdoor-planting campaigns against npm, PyPI, Crates.io, and Packagist will continue to increase in incident volume while average per-campaign novelty declines. The dominant operational signature will be scripted account creation, automated package publication across multiple registries simultaneously, and CI/CD workflow injection via forged or compromised GitHub bot identities — all executable with commodity toolkits requiring no original exploit development. At least two registry operators beyond npm will announce reactive publishing controls (mandatory 2FA, namespace-squatting detection, automated malware scanning with publication holds) within the window in direct response to volume pressure. Security vendors will report a measurable increase in "unsophisticated supply chain" incidents re

At Twio we picked pg-boss for our job queue, ran into trouble when we went serverless, looked at Pub/Sub, and ended up on Google Cloud Tasks. This is what each queue got right, what it got wrong for our workload, and the rule we landed on for choosing between them. The workload Twio is an AI SaaS for loan brokers. The piece that needs a job queue is email processing: download an email, parse the body and attachments, OCR, classify with an LLM, write structured data, and index for RAG. One email with five attachments easily becomes 30+ background jobs. A batch upload becomes hundreds. Why pg-boss worked — until it didn't Our database was Postgres on Neon, so pg-boss was the obvious starting point. No extra infrastructure, and one feature we genuinely loved: transactional enqueue . Because jobs live in the same database as business data, you can create a job in the same transaction as the row that triggered it. No dual-write problem, no "DB succeeded but the queue API failed" inconsistency. It also gave us retries, delayed jobs, dead-letter queues, dedup keys, and full SQL visibility into stuck or failed jobs. For a Postgres-first app on always-on infra, it's an excellent tool. Then we moved heavy processing to Cloud Run, and the cracks showed up. pg-boss polls. Neon suspends. They want opposite things. pg-boss runs a query roughly every 1–2 seconds to look for the next job, plus maintenance queries. Neon autosuspends compute when nothing touches the database. If the queue is polling every second, Neon's idle timer never expires — you pay for always-on compute even when the queue is empty. Worse, when Neon did manage to suspend, the next poll had to wake it. That wake-up takes hundreds of ms to a few seconds, and queries that triggered it would fail with Connection terminated , ECONNRESET , or timeouts. Pooled connections made it worse: the pool kept sockets that the server had already closed during suspend, and the next polling cycle picked one up and broke. This isn

New article: “ Responsible Disclosure in the Age of AI: A Call for Urgent Action ,” by Melissa Hathaway. Abstract: Artificial intelligence is fundamentally reshaping the balance between vulnerability discovery and remediation. Frontier AI models are now capable of autonomously identifying exploitable software vulnerabilities at unprecedented speed and scale. This development exposes decades of accumulated technical debt created by a software industry that prioritized rapid deployment over secure-by-design engineering practices. Drawing on the evolution of software assurance, vulnerability disclosure frameworks, and U.S. cyber policy, this perspective argues that the current moment represents a strategic inflection point for governments, industry, and critical infrastructure operators. The author examines the growing tension between offensive and defensive equities in cyberspace, the emergence of AI-enabled vulnerability discovery capabilities in both the U.S. and China, and the increasing risks posed by unsupported legacy systems and AI-assisted code generation practices. Responsible disclosure can no longer remain a reactive or fragmented process, but must become a coordinated national and international resilience effort involving governments, software vendors, infrastructure operators, and emergency response organizations. The article concludes with an urgent call for accelerated remediation, large-scale patch management coordination, and sustained investment in automated vulnerability repair capabilities before adversaries exploit this rapidly narrowing window of opportunity...
