By Razi Syed. Sample code for this article: github.com/dotnetreport/dotnetreport-multitenant-rls If you run a multi-tenant SaaS product on .NET, you have already solved tenant isolation for the parts of the app you wrote. Every query your code issues carries a WHERE TenantId = @tenant , or a global query filter in EF Core does it for you, and you sleep fine. Then a customer asks for reporting. Not a fixed set of reports — self-service reporting, where their analysts pick tables and c...

Apache Cassandra on the internet: where the exposed port is not the service A distributed database is a data store first and a service second. The interesting exposure is not whether a port answers but whether a client can complete a handshake and issue a query. For Cassandra those two questions are separated by a default configuration that surprises people: the native transport is often left bound to loopback while the cluster communication port is not. Context and method Co...

The three things that separate an AI demo from an AI product aren't models. They're: being able to change a prompt without a deploy, knowing what each request cost you, and not leaking a user's credit card into logs. None of these are exciting. All three are in the ChimerAI stack, so here's what they do and — more usefully — the tradeoffs they hide. 1. Prompt templates in the database Instead of prompt strings scattered across .py files, there's a PromptTemplate model with ...

I use AI to build software. I also don't trust it. That might sound strange considering most of my recent projects involve AI, LLMs, agents, RAG systems, and AI-assisted development. But after building several projects this way, I have learned something simple: Getting AI to generate code is easy. Knowing whether that code is actually good is the difficult part. AI can make you feel much more productive One of the biggest changes for me has been how quickly I can mo...

Ever hit a wall when a list grows to thousands of rows and React starts to choke? Mounting 10,000 DOM nodes at once is the problem — rendering only what fits on screen is the fix. 🧩 Overview Build a virtualized list of 10,000 contacts that mounts only the rows visible in the scroll viewport (plus a small overscan), using fixed row heights and windowing math. 👉 https://www.reactchallenges.com/challenges/virtualized-list ✅ Requirements Render a virtuali...

On August 20, 2026, Rust malware reached crates.io through one of its most-downloaded small crates. arrayref 0.3.10 added a single dependency, proc-macro1 , a look-alike of the real proc-macro2 , and that crate's build script downloaded and started a binary while your project compiled. The Rust security response team deleted it 86 minutes later . If you write Rust, the mechanism matters more than the crate: cargo build runs your dependencies' code on your machine, as you, by design. ...

A growing share of people never see your HTML. They ask ChatGPT, Claude, Perplexity or Gemini, and an agent fetches your page on their behalf. That agent has a token budget, and your cookie banner, mega-menu and 40 KB of hydration script are not what it came for. I run AskedTheAI , a shopping guide that asks four AI models the same buying question and has a human check every pick on Amazon. The site is about AI, so it would be odd if AI agents struggled to read it. Before launch I set up fou...

I made this lightweight Flask app designed to make checkout math faster, clearer, and more accurate. It helps users calculate the discount amount and final price before making a purchase or a cashiers who have to do coupons manually (like me), while keeping the logic strict enough to prevent bad input and messy rounding. [The link to the live app is below:] Open Coupon Calculator Why I built it I’ve been working toward becoming a better developer and engineer, and one of th...

AI agents are getting genuinely useful. They can read your files, install packages, call APIs, and run shell commands. That is exactly what makes them risky. If you have ever pasted an API key into an agent's environment and then held your breath while it ran, this article is for you. NVIDIA has an open source project called OpenShell that tries to solve this problem. Let's look at what it is, how it works, and whether it is worth your time. The problem in one paragraph An a...

Hi HN, I'm David. I build SaaS products and lately I've been a bit obsessed with whether ChatGPT recommends mine or a competitor's. I built Maverank's free checker to find problems I could fix on my own sites. Things like blocked crawlers, content that only loads with JavaScript, or pages that don't explain what the product does. Enter a URL and you'll get a score out of 100, a breakdown of the checks, and suggestions for what to fix. You don't need an account for the free check, but more checks...
