How to Install Tailwind CSS v4 in a .NET Blazor App (The Easy Way)

A step-by-step, beginner-friendly guide to stripping out Bootstrap and setting up the blazing-fast Tailwind CSS v4 compiler in your .NET Blazor Hybrid or Web app. Tailwind CSS v4 is officially here, and it is a complete game-changer! It scraps the old, bulky JavaScript configuration files ( tailwind.config.js ) and moves your theme settings directly into standard CSS. Plus, its new native compiler is faster than ever. If you are building a .NET Blazor app (whether it's Blazor WebAssembly, Server, or a MAUI Blazor Hybrid app) and want to swap out the default Bootstrap styles for utility-first Tailwind bliss, you can do it all without ever leaving your IDE. Let's get this configured step-by-step using Visual Studio 2022 ! Prerequisites Before we start, make sure you have: Node.js installed on your development machine. A Blazor project opened in Visual Studio 2022 . Step 1: Say Goodbye to Bootstrap in Solution Explorer Blazor templates ship with Bootstrap by default. Let's use Visual Studio's Solution Explorer to clean that out so our styles don't conflict. In the Solution Explorer window, expand your wwwroot folder. Expand the css subfolder. Right-click the bootstrap folder and select Delete . Now, open your main HTML entry file inside wwwroot (this will be index.html for Blazor Hybrid/WASM or App.razor inside the Components folder for Blazor Web). Locate the <head> section and delete the line linking the Bootstrap stylesheet: <link rel= "stylesheet" href= "css/bootstrap/bootstrap.min.css" /> powershell Step 2: Open the Developer PowerShell & Install Tailwind v4 Tailwind v4 splits the design library from the command-line build tool, so we need to install both. We can use Visual Studio's built-in terminal for this. In the top menu of Visual Studio 2022, go to Tools > Command Line > Developer PowerShell . A terminal window will open at the bottom of your IDE, already navigated to your project folder. Paste and run the following commands: i. Initialize a package.json fil

Your app can save someone from having a panic attack (a real-life story)

As I'm observing engineers, I notice that most of them share the same characteristic: unending loads of curiosity. You, software developers, are deeply interested in how things work underneath; you implement, break, troubleshoot, fix, and break again. You create apps that people use everyday and by doing so, you shape the digitalised world we live in today. Now let me share something personal: I am terrified of breaking things. I am often terrified to such an extent that I find it hard to breathe. I am suffering from something called Generalised Anxiety Disorder (GAD), which basically means I am allergic to uncertainty. While most people see trying something new as exciting, for me it's a source of stress. Every unknown step, every unfamiliar process, every situation where I don't know what comes next — it triggers something. My brain immediately goes to the worst-case scenarios. "I can't do this." "I'll do it wrong." "What if something breaks?" These thoughts don't just pop up and disappear — they pile on top of each other until they become paralyzing. But this story isn't about anxiety — it's about how good UX can change a moment from overwhelming to manageable. And how you, as a software developer, can make a real change for people who are struggling. The app that saved my day A few months ago I decided to change my mobile operator. The alternative offer had much better terms that sounded really appealing to me. No long-term contract, competitive prices, support for eSIM for travellers abroad – in short: very flexible. Head held high, I went to the new operator's office to ask them to transfer my number. But the agent quickly wiped the smile off my face. "Yes, this offer is flexible, but you need to do all the operational work yourself in the app. I can only offer you a regular long-term contract," he said. He gave me my new SIM card, and I, with a long face, went to the nearby cafe. The thought that I had to transfer my number myself felt daunting. "What if I do

Why I stopped pasting into online Fake Data Generator tools

Every online Fake Data Generator tool I used had the same quiet flaw: whatever you paste gets POSTed to someone's server. For a Fake Data Generator, that paste is often exactly the sensitive thing — a token, a config, an API response. So I built Fake Data Generator to not do that. Generate fake names, emails, UUIDs, addresses — custom columns, CSV/JSON export. 100% browser-side — and it runs entirely in your browser, so there's nothing to send and nothing to breach. You don't have to take my word for it: open DevTools → Network, use the tool, and watch the tab stay empty. One HTML file, View-Source-able. https://faker.platotools.com/ It's part of platotools.com — a set of single-purpose, client-side dev tools. Feedback and edge-case bug reports very welcome.

How to Deploy 10 Times a Day Safely with Feature Flags

If you’ve been following my previous posts, you know I’m a big advocate for Trunk-Based Development and shrinking your pull requests until they almost feel too small. In a perfect world, developers merge code directly into the main branch multiple times a day, everything flows smoothly, and production remains rock solid. But let’s be honest. When you actually try to pitch this to a backend team working on a core system, you almost always hit the exact same wall of resistance. Someone in the back of the room will inevitably raise their hand and ask: “That sounds great in theory, but I’m currently refactoring our legacy checkout service. It’s going to take me four days of deep architectural changes. Are you seriously telling me I should merge half-baked, broken code into the main trunk and push it straight to production where real customers are buying our products?” It’s a completely valid objection. If your only tool for hiding uncompleted work is holding onto a massive, long-lived feature branch, then trunk-based development breaks down immediately. You end up with the exact nightmare we talked about earlier: huge code reviews, painful merge conflicts, and code that rots before it ever sees a live environment. To make continuous delivery actually work without causing catastrophic production outages every single afternoon, you need to decouple two concepts that most engineering teams mistakenly treat as the exact same thing: Deployment and Release . Last article in this category is focused on Trunk-Based Development: https://codecraftdiary.com/2026/05/18/trunk-based-development-roadmap/ The Core Concept: Shifting Left by Decoupling In traditional development setups, deploying code and releasing a feature happen simultaneously. You merge your giant feature branch, the CI/CD pipeline runs, the code hits the live servers, and boom—your users immediately see the new functionality. This model is incredibly high-stakes. If something goes wrong, your only options are rollin

SpendWise - AI Spend Audit Tool to launch ready App

This is a submission for the GitHub Finish-Up-A-Thon Challenge What I Built SpendWise AI is a free tool that audits your AI tool spending (Cursor, Copilot, Claude, ChatGPT, Gemini, Windsurf) against verified vendor pricing and tells you exactly where you're overspending and what to do about it. I originally built this as a week-long assignment for a startup. The problem it solves is simple: founders and engineering managers pay for multiple AI tools but have no idea if they're getting ripped off. SpendWise gives them that answer in under a minute, no signup needed. The interesting part is that the core audit engine has zero AI in it. It runs 6 hardcoded rules against verified pricing data, so every recommendation is reproducible and verifiable. AI (Groq's Llama 3) only kicks in to write a friendly summary paragraph on top of the structured results. I made this choice because financial recommendations need to be deterministic. Same input, same output, every time. The stack is Next.js 16, TypeScript, Tailwind + shadcn/ui, Supabase for the database, Groq for AI summaries, Resend for emails, and Vitest for testing. Deployed on Vercel. Live app: spendwise-ai-test.vercel.app Source code: github.com/Karam-999/SpendWise-AI Demo The original audit tool: The comeback (re-audit on pricing change): You can try the Round 1 version live at spendwise-ai-test.vercel.app . Pick a tool like Cursor on Teams plan at $40/mo, run the audit, and see the full savings breakdown. The Round 2 features (pricing change detection, re-audit diff view) are on a separate branch and not merged to main yet, but the demo video above walks through the complete flow. The Comeback Story Where it was: The original version was basically a calculator. You fill in your AI tools, it shows you where you can save money, and that's it. If Cursor changed its pricing the next week, your audit was already stale and you'd never know about it. It worked fine as a one-time thing. It had the form, the audit engine, AI

I Wanted Better Insights Across My Bank Accounts, So I Built MyVault

Most side projects start with a simple frustration. Mine started with a banking app. One of my banks had a feature I really liked. It automatically categorized transactions and showed spending breakdowns in graphs and charts. For the first time, I could easily see how much I spent on restaurants, groceries, transport, subscriptions, and other categories. The problem was that only one of my banks offered this feature. Like many people, I use multiple bank accounts, credit cards, and savings accounts. Two of my other banks provided little more than a long list of transactions. If I wanted a complete picture of my finances, I had to switch between apps and manually piece everything together. As a software engineer, my first instinct was obvious: "Why don't I just build this myself?" That idea eventually became MyVault . The Original Goal The first version of the project was surprisingly simple. I wanted users to: Upload bank statements Extract transaction data Automatically categorize spending View useful charts and reports The goal wasn't budgeting. It wasn't investment tracking. It wasn't accounting. I simply wanted a single place where I could see spending across all of my bank accounts. Once I started building, however, I realized there was a much more interesting opportunity. If all transaction data was already extracted and structured, why not allow users to ask questions about their finances? Instead of searching through transactions manually, users could simply ask: How much did I spend on restaurants last year? What subscriptions am I paying for? Which categories increased the most this month? How much did I spend while traveling? That's when MyVault started evolving from a reporting tool into an AI-powered financial assistant. Building as a Solo Developer One of the biggest challenges wasn't technology. It was building everything alone. When you're working on a side project, you don't just write code. You become responsible for everything: Product decisions B

Stop the Leak: How I Built a Zero-Trust Kill Switch for Windows Using Only PowerShell

The Problem If you've ever audited your Windows network traffic during a boot-up sequence, you know the truth: there's a "blind spot." Between the moment your network drivers initialize and your VPN/WireGuard tunnel actually establishes, your traffic is leaking. Many third-party solutions exist, but they are often bloated, use proprietary binaries, or act as black boxes. I wanted something transparent, native, and bulletproof. The Solution: WG-KillSwitch I developed a pure PowerShell-based kill switch architecture. It doesn't rely on third-party libraries—it uses native Windows system components to enforce security. Key Architectural Features: Zero-Trust Firewall Matrix: Hardens the system by blocking all outbound traffic by default, allowing only authenticated tunnel traffic. WMI Persistent Watchdog: Unlike standard scripts that can be killed via Task Manager, this project uses WMI Event Subscriptions. If the watchdog process is terminated, Windows itself immediately respawns it. Resilience: Survives hard reboots, modem resets, and Windows service cycling. Resilience & Leak Testing I've put this through a gauntlet of tests: Forced Reboots: Zero leaks detected during driver load. Process Termination: The WMI engine restores the protection in milliseconds. Dynamic Network Resets: The firewall matrix remains active regardless of adapter status. Let's Collaborate This is open source, transparent, and built for the community. I'm looking for security audits and feedback. Check out the source code, open an issue, or submit a PR: https://github.com/ryderlacin-pixel/Windows-WireGuard-KillSwitch

Japanese Gothic is a gorgeously grotesque ghost story

I'll give the usual caveat: The horror novel Japanese Gothic is best experienced going in with as little information as possible. Content warnings for graphic gore, scenes of domestic violence, self-harm, and mental illness. If you're okay with that, then consider pausing here. While I will try to keep this relatively spoiler-free, there will be […]

Dell’s new XPS 14 is better in almost every way

The 2026 XPS 14 is the best premium laptop we've seen from Dell in a while, with incredible build quality in a thin machine and good performance thanks to Intel's Core Ultra Series 3 "Panther Lake" chips. A bonus: Dell killed its lame "Premium Plus" naming scheme. XPS is so back! I can't believe how […]

I built one self-hosted boilerplate and now I ship everything on it

Every time I started a side project, I rebuilt the same five things before I wrote a single line of the actual idea: auth, a database, file uploads, a deploy pipeline, and TLS. Different domain, same plumbing. By the third project I was copy-pasting my own docker-compose.yml from a folder two repos over and renaming things until they stopped erroring. So I stopped. I froze that plumbing into one boilerplate — PocketBase + Next.js + Caddy on a single cheap VPS — and now I ship every side project on it. Same shape every time: clone, rename, write the part that's actually new, push. The thing I care about most isn't the speed, though. It's that I stopped paying for it. A handful of real projects now run on this setup for a few euros a month, total — not a stack of per-service SaaS bills that each want $25 here and $20 there before you've shipped anything. No Vercel seat, no managed Postgres, no Auth-as-a-Service, no object-storage line item. Here's the whole thing. Why this stack The trick that makes the cost collapse is PocketBase . It's a single Go binary that gives you, in one process: Auth — email/password, OAuth, the works, with a real users collection A database — SQLite, with a schema you manage from an admin UI Realtime — subscribe to collection changes over SSE File storage — uploads handled, with on-the-fly thumbnails An admin dashboard — at /_/ , for free That's four or five separate SaaS products collapsed into one binary that runs anywhere and stores everything in a folder. Compared to wiring up Supabase or Firebase, the mental model is tiny: it's one process and one data directory. Back up the directory and you've backed up the entire app — database, uploaded files, auth tokens, all of it. For the front I use Next.js (App Router, React Server Components) because that's where I'm fastest, and Caddy as the reverse proxy because it gets you automatic HTTPS with zero config — it provisions and renews Let's Encrypt certificates on its own. And it all lives on

The Hypervisor Is Becoming a Policy Enforcement Point

Most organizations still think of the hypervisor as a resource abstraction layer. CPU. Memory. Storage. The platform that decides where workloads run. That mental model is increasingly incomplete. Every major virtualization platform — vSphere, AHV, Proxmox — has been steadily accumulating policy enforcement responsibilities. The hypervisor isn't just deciding where workloads run. It's increasingly deciding what they're allowed to do. The Speed of the Shift Is the Real Story Virtualization practitioners already know security controls have moved downward through the stack. What's less appreciated is how compressed the most recent phase has been. For years, hypervisors enforced resource allocation. Within a single platform generation cycle, that same layer accumulated encryption policy enforcement, workload trust validation, microsegmentation, secure boot enforcement, host attestation, and workload isolation boundaries — not as optional add-ons, but as core platform capabilities. The perimeter-to-OS transition took decades. The hypervisor accumulated a comparable policy enforcement surface in the time between one major vSphere release and the next. That compressed timeline is what creates the ownership lag — the governance model adequate for a resource scheduler has not caught up to a platform that enforces organizational policy. The Hypervisor Now Makes Binding Decisions The distinction that matters: a platform that observes policy versus a platform that enforces it. The hypervisor is no longer observing. It is enforcing. VM fails attestation → workload does not start. Encryption policy mismatch → workload cannot migrate. Segmentation policy violation → communication blocked at the platform layer. Trust validation failure → host removed from workload eligibility. Those are not scheduling decisions. Those are governance outcomes. The workload doesn't get a vote. This is what makes the hypervisor governance infrastructure : infrastructure that directly enforces organiza

The Complete iOS Icon Size Guide for 2026 and Beyond

If you have ever submitted an iOS application to Apple's App Store and received a cryptic rejection notice about icon specifications, you are not alone. Apple's human interface guidelines for icons are extraordinarily precise — and for good reason. The iOS ecosystem spans devices from the tiny Apple Watch to the expansive iPad Pro, each requiring icons at exact pixel dimensions to render correctly across Retina, Super Retina XDR, and ProMotion displays. Understanding iOS icon sizes is not optional. It is a prerequisite for shipping. Every pixel dimension you provide must match Apple's specifications exactly, must use lossless PNG format, must not include transparency, and must be delivered with the exact filename that Xcode expects. One missed size, one wrong filename, and your project fails to build correctly. Precision is not a suggestion — it is a hard requirement enforced by Xcode's build system. iPhone Icon Sizes For iPhone applications, the required icon sizes span multiple uses within the operating system. The App Store listing requires a 1024×1024 pixel icon. The home screen displays icons at different sizes depending on device generation and display density. Notification icons, Spotlight search results, and Settings app icons all require their own specific dimensions. Usage Scale Size (px) Filename Convention App Store 1× 1024×1024 Icon-1024.png Home Screen 2× 120×120 Icon-60@2x.png Home Screen 3× 180×180 Icon-60@3x.png Spotlight 2× 80×80 Icon-40@2x.png Spotlight 3× 120×120 Icon-40@3x.png Settings 2× 58×58 Icon-29@2x.png Settings 3× 87×87 Icon-29@3x.png Notification 2× 40×40 Icon-20@2x.png Notification 3× 60×60 Icon-20@3x.png iPad Icon Sizes iPad adds its own set of required sizes, particularly because of the larger screen real estate and different display densities. Xcode's asset catalog system requires each icon to be placed in the correct slot, and any missing slot will prevent archiving for App Store submission. This makes completeness not just a best p

How to Find and Fix 11 Common SEO Issues Using Chrome DevTools

Search engine optimization doesn't require expensive tools. Your browser's built-in developer tools can identify and diagnose most SEO problems in under 15 minutes. Here are the 11 most impactful SEO checks you can run directly from Chrome DevTools. 1. Check Meta Description Length Right-click any element, Inspect, expand <head> , find <meta name="description"> . Metric Optimal Range Meta description length 120-155 characters Title tag length 50-60 characters H1 count per page Exactly 1 const meta = document . querySelector ( ' meta[name="description"] ' ); const len = meta ? meta . content . length : 0 ; console . log ( `Meta description: ${ len } chars` ); 2. Verify Only One H1 Tag Exists const h1s = document . querySelectorAll ( ' h1 ' ); console . log ( `H1 count: ${ h1s . length } ` ); A study of 1.2 million pages found pages with one H1 ranked 12% higher on average. 3. Find Images Missing Alt Text const imgs = document . querySelectorAll ( ' img ' ); const missing = [... imgs ]. filter ( i => ! i . alt || i . alt . trim () === '' ); console . log ( ` ${ missing . length } of ${ imgs . length } images missing alt text` ); Pages with complete alt text see 3.7% higher image search visibility. 4. Detect Render-Blocking Resources Open DevTools, Network tab, reload, click "Blocking" filter. Resources in red block first contentful paint. Total blocking time under 200ms More than 20 render-blocking resources signals a problem Each render-blocking CSS file adds 50-300ms to page load 5. Check Canonical Tag Consistency const canonical = document . querySelector ( ' link[rel="canonical"] ' ); console . log ( canonical ? `Canonical: ${ canonical . href } ` : ' No canonical tag ' ); 6. Audit Internal Links const links = [... document . querySelectorAll ( ' a[href] ' )]; const internal = links . filter ( l => { try { return new URL ( l . href ). hostname === window . location . hostname ; } catch ( e ) { return false ; } }); console . log ( `Internal links: ${ internal . len
