A platform is a collaboration system: platform teams depend on application teams, and both need shared standards. Engineers trust a platform through its predictable behavior, not its features. Being an engineer is about problem-solving and being passionate about it. And being an engineer means sharing your passion for problem-solving. By Ben Linders

Because of the way they are trained, large language models capture only a slice of human language. They’re trained on the written word, from textbooks to social media posts, and our speech as captured in movies and on television. These models have minimal access to the unscripted conversations we have face to face or voice to voice. This is the vast majority of speech, and a vital component of human culture. There’s a risk to this. The increased use of large language models means we humans will encounter much more AI-generated text. We humans, in turn, will begin to adopt the linguistic patterns and behaviors of these models. This will affect not just how we communicate with one another, but also how we ...

The Kubernetes community has introduced a framework for integrating AI into open-source maintainership, emphasising human accountability in code quality and oversight. AI tools may streamline workflows, but ultimate responsibility lies with human maintainers. The framework requires disclosure of AI usage in contributions and prohibits AI-generated commit messages.

If you've ever written test data by hand, you know the ritual: a PersonBuilder , an OrderBuilder , an AddressBuilder … one hand-written builder per class, each one a wall of WithX(...) methods you have to maintain forever. The Test Data Builder and Object Mother patterns are great — the boilerplate is not. XModelBuilder gives you a fluent builder for any C# class out of the box. No per-class builder required. It handles constructor parameters, init-only properties, read-only members, even private backing fields — via reflection, deterministically. Install dotnet add package XModelBuilder 30-second example You can use it fully standalone (no DI container) through a small static facade: using XModelBuilder.Default ; var order = For . Model < Order >() . With ( x => x . OrderDate , new DateTime ( 2026 , 7 , 1 )) . With ( x => x . Lines [ 0 ]. Product , "Widget" ) // deep paths + indexers just work . With ( x => x . Lines [ 0 ]. Quantity , 3 ) . Build (); No OrderBuilder , no OrderLineBuilder . The Lines[0].Product path drills into a nested collection element and sets it for you. Need a whole list? Create.Models<Order>(10) . Deterministic fakers, seeded once Random test data that changes every run is a debugging nightmare. XModelBuilder ships a seeded, dependency-free faker (and a Bogus integration if you prefer). Register it once: services . AddXModelBuilder () . AddXFaker ( seed : 12345 ); // reproducible values, every run Then let it fill in the noise while you set only what your test actually cares about: var order = xprovider . For < Order >() . With ( x => x . Id , p => p . XFake (). NewGuid ()) . With ( x => x . Customer . Name , p => p . Bogus (). Company . CompanyName ()) . With ( x => x . Lines [ 0 ]. Quantity , 3 ) . Build (); XFake().NewGuid("customer-acme") even gives you a stable GUID from a name — same key, same GUID, regardless of call order or parallelism. Deterministic by design. Build a whole list: BuildMany Need ten of something, each slightly differ

This post was originally published on MatrixTrak.com — the production reliability toolkit for trading bot operators and .NET engineers. When requests hang forever and recycling releases stuck work: why missing timeouts create backlog, how to add budgets safely, and the rollout plan that prevents new incidents.. Most production incidents do not start as "down." They start as waiting. At 09:12 a dependency slows down. Your ASP.NET instances look healthy. CPU is fine. Memory is fine. But requests stop finishing. In-flight count climbs. Connection pools stop turning over. You scale out and it does not help because the new instances just join the waiting. The cost is not subtle. Backlog grows, SLAs fail, and on-call starts recycling processes because it is the only thing that releases the stuck work. Then the incident repeats next week because nothing changed about the waiting. This post gives you a production playbook for .NET: how to set time budgets, wire cancellation, and roll it out without triggering a new outage. Rescuing an ASP.NET service in production? Start at the .NET Production Rescue hub . If you only do three things Write down a total budget per request/job (then enforce it). Set per-attempt timeouts for each dependency and log elapsedMs , timeoutMs , and the decision (retry/stop/fallback). Propagate cancellation end-to-end so work stops (no zombie work after timeouts). Why requests hang forever: infinite waits capture capacity Missing timeouts are not a performance problem. They are a capacity problem. When a call can wait forever, it will eventually wait longer than your system can afford. While it waits, it holds something your service needs to operate: a worker slot, a thread, a connection, a lock, or a request budget. Once enough requests or jobs are holding those resources, the system stops behaving like a service and starts behaving like a queue you did not design. From the outside it looks like "everything is slow." Underneath, you are accumulating

Bạn sẽ học gì Sau bài này, bạn sẽ tự tay đưa một app từ số 0 (một thư mục trống) đến chạy được bên trong một cluster Kubernetes chạy trên máy của bạn . Cụ thể: Viết một app Todo API nhỏ bằng Node.js + Express. Đóng gói (container hoá) nó thành một Docker image. Tạo một cluster Kubernetes local bằng kind . Deploy app bằng file YAML "thật" (không dùng lệnh tắt) để hiểu Kubernetes vận hành thế nào. Truy cập app đang chạy trong cluster từ máy của bạn. Đây là Part 1 trong series "DevOps 101 — Học K8s, Helm, ArgoCD từ số 0" .

Starting on August 3rd, Netflix's streaming library will include video content from dozens of digital media brands including BuzzFeed, Condé Nast, Hearst Magazines, People Inc, and Tastemade. As reported earlier by TechCrunch, the deal includes a mix of licensed past videos and new ongoing series that would have typically been published on YouTube or other […]

Netflix is bringing 2- to 20-minute videos to its platform through new partnerships with digital publishers, including Rolling Stone and Variety.

A new report suggests Netflix viewers aren’t sticking around for Season 2. The bigger issue may be that binge-watching itself is no longer the advantage it once was.

Developers love building things. Sometimes the hardest part isn't writing code—it's organizing data. Over the past few months, I've been building a large SVG library containing more than 180,000 vector files. At first, I assumed collecting the files would be the biggest challenge. I was wrong. The real challenge was organizing them. The Duplicate Problem Once a collection reaches hundreds of thousands of files, duplicates become unavoidable. Different sources often contain identical icons with different filenames. For example: facebook.svg facebook-logo.svg facebook-icon.svg facebook-black.svg facebook-circle.svg Some of these are genuine variations. Others are simply duplicates from different icon packs. Automatically detecting the difference isn't always easy. Collections Instead of Files Instead of treating every SVG as an individual page, I decided to build everything around collections. Examples include: Facebook Docker Kubernetes Payment Icons Weather Icons Medical Icons Programming Languages Each collection groups similar SVGs together, making browsing much easier than searching individual files. Keeping Search Engines Happy One interesting problem appeared during development. Should every individual SVG page be indexed? After experimenting with different structures, I chose a different approach. Only complete, content-rich collections are indexed. Individual SVG pages remain accessible but are excluded from search engine indexes. This avoids creating hundreds of thousands of thin pages while allowing search engines to focus on pages that actually provide value. Automation Managing thousands of collections manually isn't realistic. Several background scripts now automate most repetitive tasks: Collection descriptions Meta titles Meta descriptions FAQ generation Sitemap updates Controlled indexing This allows the library to continue growing without requiring manual editing for every collection. Data Cleanup One task I underestimated was cleanup. Large datasets

Originally published on DevToolHub . Helm 4 shipped in November 2025. Eight months later, most teams are still running Helm 3 in production CI/CD because it works. But Helm 3's final feature release lands September 9, 2026, and security patches stop completely on February 10, 2027. This helm 4 migration is simpler than it looks. Your charts don't need rewriting — Helm 3 Chart API v2 charts are fully compatible with Helm 4. But the automation around Helm has four real breaking points that fail silently if you don't know where to look. [IMAGE: articles/images/2026-07-05-helm-4-migration-guide-featured.png | alt: "helm 4 migration flow from Helm 3 to Helm 4 upgrade path"] Why This Helm 4 Migration Matters Now The EOL timeline has three stages, and they matter differently based on your situation: September 9, 2026 — Final Helm 3 feature release (limited to Kubernetes client library updates only after this date) February 10, 2027 — All security patches stop If your organization runs regulated workloads with requirements around supported software, February 2027 is your hard deadline. But waiting until then means doing this migration under pressure, after 14 months of Helm 4 fixes shipped without you tracking them. The better path: upgrade now, before September, so you're on supported software when new Kubernetes releases land and need updated client libraries. What Actually Broke: The Four Real Changes 1. Post-renderers require plugin registration In Helm 3, you could pass any executable directly to --post-renderer : helm install myapp ./chart --post-renderer ./scripts/mutate.sh Helm 4 drops this. Post-renderers must now be registered as named Helm plugins and referenced by plugin name: helm install myapp ./chart --post-renderer my-post-renderer If your pipeline calls --post-renderer ./path/to/script.sh , it fails on Helm 4. The error message doesn't say "plugin required," so this is easy to miss in a quick smoke test. To wrap an existing script as a plugin, create a plug

I'm launching SmartTaxCalc.in on Product Hunt on Tuesday, 14 July 2026 . It's a 38-tool Blazor WebAssembly tax + finance calculator I've written about here before ( the SEO/schema saga , and dropping mobile LCP from 6-8s to under 2s ). The Product Hunt launch algorithm heavily rewards products that arrive with a real coming-soon follower base — day-of upvotes correlate strongly with pre-launch "Notify me" clicks. My PH page started with 1 follower . I had 9 days to get to 50+. The obvious answer: post on LinkedIn, ask friends, DM your network. All of that has ceilings (you can only ask a favor once). The non-obvious answer that has no ceiling: convert your own organic search traffic into PH followers automatically. This is the ~100 lines of Blazor code that does that, plus the design decisions I made along the way. It's also self-cleaning — after the launch date, the banner disappears with no manual work required. Steal the pattern for your own launch. The problem SmartTaxCalc gets modest but real organic traffic — mostly from Google Search Console impressions on tax-season queries. That traffic is the warmest possible audience for a PH launch (they already found the site, they're in the target demo). But how do you route them to a PH page without: Disrupting the tax content (they came for a tax calculator, not a marketing pitch) Cannibalizing the existing tax-season banner (which drives users to /tax-calendar/ — a real retention lever) Leaving code debt after 14 July (a dead PH banner still on the site in September) Losing the dismiss preference across page navigations (SPA reality — no page refresh) Those constraints ruled out a modal, a full-width interrupt, and a "hardcoded remove after launch" approach. The design Slim horizontal bar at the top of every page. Sits ABOVE the existing tax-season banner. PH-brand orange, different from the tax-season banner's yellow/red so both are visually distinguishable when stacked. Dismissible per-user via localStorage . Auto

ASP.NET Core: Building High-Performance Web Applications and APIs A practical guide to ASP.NET Core — the cross-platform framework for building REST APIs, MVC applications, and backend services on .NET, covering architecture, minimal APIs, middleware, performance, and modern patterns. Table of Contents Introduction Architecture Overview Minimal APIs MVC and Controllers Middleware Pipeline Dependency Injection Configuration and Options Authentication and Authorization Performance Features Testing and Observability Quick Reference Table Conclusion Introduction ASP.NET Core is a free, open-source, cross-platform framework for building web apps, APIs, and backend services. It's a ground-up rewrite of the original ASP.NET, designed around three priorities: Performance — it's consistently one of the fastest mainstream web frameworks in independent benchmarks (e.g., TechEmpower). Modularity — you opt into only the middleware and services your app actually needs, instead of a fixed, heavyweight pipeline. Cross-platform — runs identically on Windows, Linux, and macOS, and deploys to containers, serverless, or bare metal. This guide covers the core building blocks you'll use in almost any ASP.NET Core project, from a five-line minimal API to a full MVC application with authentication and background services. 1. Architecture Overview Every ASP.NET Core app starts from a unified entry point — Program.cs — using the minimal hosting model introduced in .NET 6. var builder = WebApplication . CreateBuilder ( args ); // Register services (dependency injection container) builder . Services . AddControllers (); builder . Services . AddEndpointsApiExplorer (); builder . Services . AddSwaggerGen (); var app = builder . Build (); // Configure the HTTP request pipeline (middleware) if ( app . Environment . IsDevelopment ()) { app . UseSwagger (); app . UseSwaggerUI (); } app . UseHttpsRedirection (); app . UseAuthorization (); app . MapControllers (); app . Run (); Two phases matter here:

Distributed backups, cyber resilience, and a half-million records are preserving Palestinian history beyond any single building or border.

I fine-tuned Gemma 4 E2B. The adapter merged cleanly. The export to .litertlm completed without errors. I pushed the model to my phone, initialized the engine, and everything looked green. Then I tried to create a conversation and got this: Failed to apply template: unknown method: map has no method named get (in template:238) No model loading failure. No quantization error. The model initialized, the tokenizer loaded, and then the runtime choked on a Jinja template feature it does not support. This failure only surfaces when you actually try to run inference, not when you load the model. If you are demoing at a hackathon, this is the worst possible time to discover a compatibility issue. I hit this exact bug while building Redacto, a zero-trust PII redaction app that runs Gemma 4 E2B entirely on-device. This post walks through the full fine-tune-to-deploy pipeline: how to QLoRA a model on Colab, export it for LiteRT-LM, and avoid the undocumented template trap that will block your deployment. The Full Pipeline Here is what the fine-tune-to-deploy pipeline looks like end to end: HuggingFace base weights -> QLoRA fine-tune (Colab) -> Merge adapter into base -> Patch chat template <-- the step nobody tells you about -> Quantize + export to .litertlm -> Push to device Each stage has its own failure modes. The template patch step is the one that was undocumented at the time, and it is the one that will cost you hours if you do not know it exists. A note on framing before we dig in: this was an under-resourced fine-tune. I trained on 3,000 of the 400,000 samples in the ai4privacy/pii-masking-400k dataset for a single epoch, and the label format did not fully match what Redacto expected downstream. The point of this post is not the fine-tune's accuracy - it is the deployment mechanics I had to work through to get any fine-tuned model onto the device at all. Step 1: QLoRA Fine-Tuning on Colab QLoRA (Quantized Low-Rank Adaptation) lets you fine-tune a quantized model by tra

🎲 A Tale of Inference Woes 🎲 Thy context window overflows with dread, Thy API keys scattered 'cross thy thread. Thou switchest providers mid-conversation, And pray thy tokens find the right foundation. No ward stands guard when tools go rogue, No grimoire saves a session from the fog. Thy agents wander, masterless and blind, Thy prompts untested—leaving truth behind. Thy wallet weeps. Thy latency doth creep. Thy model's fine. Thy infrastructure? Not so deep. Sound familiar? I'm excited to share the public README for Arcanum — a .NET 10, single-binary, Native AOT, local-first AI inference hub that treats your infrastructure with the seriousness of a dungeon master and the organization of a well-kept grimoire. Arcanum is one self-contained native executable. No runtime prerequisite. No "install the framework first." Just arcanum serve and you're running a full inference platform on loopback. What's in the bag of holding: 🏰 Local-first & encrypted — SQLCipher-encrypted Grimoire persists every session, entry, and memory. Your data never leaves your machine unless you tell it to. ⚔️ Multi-provider native engine — Any OpenAI-compatible API (DeepSeek, Groq, Ollama via /v1, LM Studio, etc.) plus local GGUF models via a managed llama-server lifecycle. One hub, zero vendor lock-in. 🔮 OpenAI API compatible — POST /v1/chat/completions and GET /v1/models work with existing OpenAI clients out of the box. Drop-in replacement for your local stack. 🛡️ Wards & Sanctum — High-risk tools require operator approval before execution. Per-campaign sandboxes enforce path containment, network policy, and OS-level CPU/memory/FD limits via cgroups v2 and setrlimit. 📜 Spells, not prompts — Versioned markdown workflows with dependency resolution, tool allowlisting, and semantic routing. Dry-run cast previews before spending a single token. 🧙 Autonomous Apprentices — Goal-driven agents with plan generation, retry/backoff, autonomous plan revision, DM escalation, and parallel step execution. 🏰 The

"Docker vs Kubernetes" is one of those framings that quietly sends people down the wrong road. It sounds like a choice between two competing tools, so teams treat it like a bake-off. It isn't. Docker builds and runs containers. Kubernetes orchestrates a fleet of them. You can happily use one without the other, and most teams should — at least for a while. The question that actually matters is hiding underneath: do I need an orchestrator yet? That's the one worth thinking about carefully, because the cost of answering "yes" too early is real, and it mostly shows up later, on a Saturday, when you're the one holding the pager. What each tool actually does Let me separate the two cleanly, because the confusion causes most of the bad decisions. Docker (or any OCI-compatible runtime — Podman, containerd, and friends) does two jobs: it builds an image from a Dockerfile , and it runs that image as a container on a host. That's the unit of packaging. When you type this: docker build -t registry.example.com/myapp:1.4.2 . docker run -d -p 8080:8080 registry.example.com/myapp:1.4.2 you've packaged your app and started it on one machine . If that machine dies, your app dies with it. If you need three copies, you start three by hand. If you push a bad image, you roll it back by hand. Kubernetes doesn't build or run containers itself — it schedules them across a set of machines and keeps them in the state you declared. You tell it "I want three replicas of myapp:1.4.2 , behind a stable network name, and if a node dies, reschedule them." Kubernetes then spends its life making reality match that declaration. So they're not competitors. Kubernetes runs your Docker-built images. The real comparison isn't "Docker vs Kubernetes" — it's "a couple of containers on a host I manage" versus "a control plane that manages containers for me." A small, honest comparison Concern Plain Docker (or Compose) Kubernetes Where it runs One host you manage A cluster of nodes If a node dies You notice and

If you're comfortable with docker compose up , you already understand more of Kubernetes than you think. Compose taught you to describe an application declaratively — services, their images, their config, how they talk to each other — instead of running containers by hand. Kubernetes is the same instinct, scaled out across a cluster, with more moving parts because it's solving a harder problem: keeping that application running when machines fail. The good news is the mental model transfers. The honest news is that the operational surface grows, and it's worth knowing exactly what changes before you commit. Let me map the concepts you already know onto their Kubernetes equivalents, show the YAML side by side, and be straight about the parts that get harder. First, the thing that doesn't change: your images This trips people up, so let's clear it early. The Docker images you already build run on Kubernetes unmodified. Kubernetes doesn't use the Docker daemon to run them — most clusters use containerd or CRI-O — but every one of those runtimes runs standard OCI images. That's the whole point of the OCI standard: the image you built with docker build is the same artifact the cluster pulls and runs. docker build -t registry.example.com/myapp:1.4.2 . docker push registry.example.com/myapp:1.4.2 That image works identically whether docker run starts it or a Kubernetes node's containerd does. So the packaging is settled. What changes is everything around the container. The concept map Here's the translation table I'd keep next to you while you learn: Docker Compose Kubernetes What changed service Deployment + Service Running vs. reachable are now two objects image: spec.containers[].image Same OCI image ports: Service (+ Ingress for external) Networking is explicit and named depends_on: probes / initContainers Ordering becomes health, not sequence environment: / .env ConfigMap / Secret Config decoupled from the pod volumes: PersistentVolume / PVC Storage is claimed, not jus
