You asked, we delivered! 👉 New tutorial is live: https://lnkd.in/dexcnpGc After our #Kafka explainer video, many of you were asking for a hands-on demo. Here's the thing about learning tech - understanding the theory is just step one. But until you've actually written the code, started the services, and seen the data flow... it doesn't really click. So we built a hands-on follow-up: 1-𝗵𝗼𝘂𝗿 𝗞𝗮𝗳𝗸𝗮 𝗰𝗿𝗮𝘀𝗵 𝗰𝗼𝘂𝗿𝘀𝗲 with Python and Docker. Because there's a huge difference between knowing about message queues and actually building with them. 𝗧𝗢𝗣𝗜𝗖𝗦 𝗖𝗢𝗩𝗘𝗥𝗘𝗗 First you'll understand conceptually: ↳ WHAT Kafka is and WHY Kafka was developed? What PROBLEM does it solve? ↳ How Kafka achieves scalable performance? ↳ Kafka vs Other Message Brokers? Then get hands-on with a simple but realistic demo project: ↳ Run Kafka Broker with Docker Compose ↳ Write a Kafka Producer ↳ Write a Kafka Consumer ↳ Using Kafka CLI - Kafka Commands ↳ Troubleshooting tips It is a step by step guide, to make sure you can follow smoothly and understand every step clearly.

I tried Uno Platform to build a quick tool for myself… and didn’t expect this. Turns out, building a real cross-platform app - desktop, web, and mobile - is way easier than I thought. I always thought Uno Platform was mainly for mobile - kind of like a Xamarin clone. But I was wrong. Uno Platform is a full cross-platform framework for: • Web (via WebAssembly) • Windows (WinAppSDK) • macOS, Linux • iOS & Android And it uses C# and XAML - perfect for .NET developers. I built a tiny Weather app and designed it live with Uno Platform Studio - no rebuilds. Uno Platform Studio (paid) is a companion that adds: • Hot Design (live visual designer on your running app) + Hot Reload. • Edits apply instantly and write back to your XAML. • With Hot Design you can change spacing, tweak colors, switch device sizes, and toggle light/dark while the app is running. • Real data, real states - what you see is what you ship. Under the hood it’s Uno Platform (open source). Uno Platform let me write one app in C# and XAML and run it: 1. As a native desktop app (WinUI) 2. As a mobile app on Android and iOS 3. As a web app (thanks to WebAssembly) And I didn’t need to change the UI code for each platform. Even better? The open-source tooling feels very familiar if you've ever used WPF or MAUI. Setup: uno-check --fix → wizard → run. Familiar MVVM, DI, HttpClient. In the slides below you can see how to install Uno Platform and configure your project. • Check Uno Platform here: https://lnkd.in/dPihsfzu • Check Uno Platform Studio here: https://lnkd.in/dnXPmUAu What would you build if you could design live and ship everywhere?

🚀 Freelance vs Full-time Software Development in Germany - When to choose what In Germany's technology market, both freelance developers and permanent employees play important roles. The right choice depends on your business needs. ✅ Freelancers are the better choice when ⚡You need very specific expertise for a clearly defined project or technology stack ⚡Speed is important, since freelancers can usually start quickly without long hiring processes ⚡Your workload is project-based and does not justify a permanent hire ⚡You want flexibility to scale teams up or down without long-term obligations 👩‍💻 Permanent employees are the better choice when ⚡You want to build long-term product knowledge and strong company culture ⚡Continuity in core systems is essential ⚡The role requires deep integration with the business and its processes In short: 👉 Choose a freelancer for focus, speed, and flexibility 👉 Choose a permanent employee for stability, culture, and continuity The value lies in knowing which model fits your current challenge. #Freelance #SoftwareDevelopment #TechHiring #ITFreelance

𝗜 𝗮𝗺 𝗮𝗳𝗿𝗮𝗶𝗱 𝗼𝗳 𝗰𝗼𝗱𝗶𝗻𝗴, 𝐈 𝐰𝐚𝐭𝐜𝐡 𝐭𝐮𝐭𝐨𝐫𝐢𝐚𝐥𝐬 𝐚𝐧𝐝 𝐠𝐨 𝐭𝐡𝐫𝐨𝐮𝐠𝐡 𝐜𝐨𝐮𝐫𝐬𝐞𝐬 𝐛𝐮𝐭 𝐬𝐭𝐢𝐥𝐥 𝐮𝐧𝐚𝐛𝐥𝐞 𝐭𝐨 𝐰𝐫𝐢𝐭𝐞 𝐭𝐡𝐞 𝐩𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐢𝐧𝐠 𝐥𝐨𝐠𝐢𝐜 But the moment I had to write code from scratch, my mind would go completely blank. Sound familiar? Here's the thing - I thought I was the only one struggling with this. But after talking to dozens of Devs/Sdets, I realized this is incredibly common. 👉 The problem isn't that we don't understand programming. The problem is that we're trying to learn coding the same way we learned other subjects in school. 𝐖𝐡𝐲 𝐭𝐮𝐭𝐨𝐫𝐢𝐚𝐥𝐬 𝐝𝐨𝐧'𝐭 𝐭𝐞𝐚𝐜𝐡 𝐲𝐨𝐮 𝐭𝐨 𝐭𝐡𝐢𝐧𝐤 𝐥𝐢𝐤𝐞 𝐚 𝐩𝐫𝐨𝐠𝐫𝐚𝐦𝐦𝐞𝐫 When you watch a tutorial, you're seeing the final solution. You don't see the instructor's thought process, the dead ends they explored, or the mistakes they made along the way. Staring at a blank code editor not knowing where to start - Getting stuck on simple problems that seemed easy in tutorials - Feeling like a fraud when I couldn't solve basic coding questions - Avoiding coding interviews because I was terrified of live coding - Wanting to build projects but not knowing how to begin 𝐖𝐡𝐚𝐭 𝐚𝐜𝐭𝐮𝐚𝐥𝐥𝐲 𝐡𝐞𝐥𝐩𝐞𝐝 𝐦𝐞 𝐨𝐯𝐞𝐫𝐜𝐨𝐦𝐞 𝐭𝐡𝐢𝐬 𝐟𝐞𝐚𝐫?, 𝐒𝐭𝐚𝐫𝐭 𝐰𝐢𝐭𝐡 𝐭𝐡𝐞 𝐩𝐫𝐨𝐛𝐥𝐞𝐦, 𝐧𝐨𝐭 𝐭𝐡𝐞 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧! Instead of jumping straight into code, I learned to spend time understanding what the problem is really asking. - I write down the problem in simple English first. 𝐁𝐫𝐞𝐚𝐤 𝐞𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠 𝐢𝐧𝐭𝐨 𝐭𝐢𝐧𝐲 𝐬𝐭𝐞𝐩𝐬 - I learned to take any coding problem and break it down into the smallest possible piece. 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐞 𝐭𝐡𝐞 "𝐞𝐱𝐩𝐥𝐚𝐢𝐧 𝐢𝐭 𝐭𝐨 𝐚 𝐟𝐫𝐢𝐞𝐧𝐝" 𝐦𝐞𝐭𝐡𝐨𝐝 I learned to explain my approach out loud as if I'm teaching someone else. This helps me catch logical gaps in my thinking before I start coding. 𝐀𝐜𝐜𝐞𝐩𝐭 𝐭𝐡𝐚𝐭 𝐠𝐞𝐭𝐭𝐢𝐧𝐠 𝐬𝐭𝐮𝐜𝐤 𝐢𝐬 𝐧𝐨𝐫𝐦𝐚𝐥 The biggest mindset shift was realizing that professional developers get stuck all the time. The difference is they've learned to be comfortable with the process of working through problems step by step. 𝐒𝐭𝐚𝐫𝐭 𝐰𝐢𝐭𝐡 𝐯𝐚𝐫𝐢𝐚𝐭𝐢𝐨𝐧𝐬 𝐨𝐟 𝐩𝐫𝐨𝐛𝐥𝐞𝐦𝐬 𝐲𝐨𝐮'𝐯𝐞 𝐬𝐞𝐞𝐧 Instead of trying to solve completely new problems, I started with small variations of tutorial problems. This helped me build confidence while gradually developing independent thinking. ✅ Programming isn't about memorizing syntax or knowing every function. It's about developing problem-solving skills and learning to think in small, logical steps. ✅ You just need to take the next small step.

🧠What is a #StoredProcedure, and Why is it important? A Stored Procedure is a combination of #SQL queries that can be executed together in a #SingleCall. It allows us to #Automate repetitive database operations, improve performance, and make our SQL code more organized and reusable. In simple terms - instead of writing the same queries again and again, we can create a procedure once and call it whenever needed. The below image gives a detailed visual explanation of how a stored procedure works. from creating a table, changing the delimiter, writing the procedure block, and executing it with inputs to dropping it safely if it already exists. This concept is highly useful in real-time projects where efficiency and consistency in database management are crucial. #SQL #StoredProcedure #Database #MySQL #DataEngineering #DataAnalytic #Darshanikanta
