Default values are important to make software frictionless. Developers exposes a parameter and set a default value that meets the general case and users don’t have to bother with them much. However, when a default value doesn’t meet the system requirements or worse changed from one release to another it can have significant performance regression. In this podcast, I tell a story about a change in default value in Postgres 14 that caused a performance regression. This is the story of the INDEX_CLEANUP = AUTO which used to be INDEX_CLEANUP = ON on PG13 and earlierc a parameter that lets vacuum clean up index’s dead tuples, not a trival operation. Let us dive into it. https://lnkd.in/gwrkQcCN

During our hiring process for the SE1 position, my mentor and manager, Mohammed Ibrahim Islam, suggested an innovative idea for the assignment, and prepared the question as well! Instead of the typical "build from scratch" task, we provided a fully functional Python app with a readme, unit tests, and setup commands. The challenge? Candidates had to fix any bugs, enhance performance, and refactor the code for better readability and maintainability. The response was incredible! Candidates enjoyed working on real-world code, optimizing it, and learning from others' implementations. The best part? It saved them time while giving us insightful submissions. With unit tests and pre-set commands, evaluation was seamless, making the process both efficient and effective. I highly recommend rethinking how we give assignments during hiring. Focusing on practical, real-world scenarios can make all the difference! #HiringProcess #CodeOptimization #TechRecruitment #UnitTesting #CodeRefactoring

🚀 AI in Development: A Game-Changer or a Gamble? 🤔 As a C# ASP.NET Core developer working remotely for a foreign company, I’ve experienced firsthand how different cultures and companies view AI tools like ChatGPT. One thing that really stands out is the difference between my interviews in Iran, where some technical managers are hesitant to adopt AI, and my current role, where AI is fully embraced. 💡 The big question is: Should developers be encouraged to use AI tools like ChatGPT, or should there be more caution around their use? A big thank you to Soheil Alavi for creating such an insightful video! 🙏 Your content really highlighted the contrasting perspectives on AI adoption in tech, and it’s sparked some great discussions. Keep up the amazing work! 👏 Poll: 1. Fully Embrace AI in Development 2. Use AI with Caution 3. AI is Unnecessary 4. It Depends on the Role I’d love to hear your thoughts!

👨‍💻 Developers' Insight: After working on multiple file upload projects, I’ve found that saving only the file name in the database while generating the full file path in the application code is the most efficient approach. 💡 🔍 Here’s why I believe this works best: 📂 Flexibility:  Switch from local to cloud storage without database changes. 🛠 Simplicity: Keeps the database clean and organized. ⚙️ Scalability: Ensures your app grows smoothly. This method has proven effective for both small and large-scale applications! 🚀 What do you think? Do you follow a similar approach? #Laravel #WebDevelopment #CleanCode #DeveloperTips #BestPractices

In my experience, integrating APIs on the frontend requires careful attention to several key practices to ensure a smooth and efficient user experience: Loading and Empty States: Implement loading and empty states wherever API calls are made to provide users with appropriate feedback while data is being fetched. 1. Form Validations: Ensure proper form validations to maintain data integrity. Formik is an excellent tool for handling this effectively. 2. Number Inputs: Prevent special characters in number inputs by using regular expressions to enforce proper input formatting. 3. Error Handling: Provide meaningful feedback to users when errors occur, guiding them to resolve issues or understand what went wrong. 4. Dynamic Data Rendering: Anticipate potential API failures or undefined responses when rendering dynamic data on the frontend. Write resilient code that gracefully handles such scenarios. 5. Pagination: Use pagination for large datasets to load data incrementally, improving performance and user experience. 6. Debouncing API Calls: Implement debouncing techniques for API calls triggered by user input to reduce unnecessary calls. For example, debounce search API requests to enhance efficiency. By adhering to these practices, you can build robust and user-friendly frontend applications that handle API integrations seamlessly.

I am fascinated by how timeouts affect backend and frontend programming. When a party is waiting on something you can place a timeout to break the wait. This is useful for freeing resources to more critical processes, detecting slow operations and even avoiding DOS attacks. Contrary to common beliefs, timeouts are not exclusive to request processing, they can be applied to other parts of the frontend-backend communications. Let us explore this briefly. A client sends an HTTP request. To do so it needs to establish a connection with the server, the connection establishment (including TLS) takes time, this is often called connection timeout. When the client prepares the request and writes it to the connection socket, that also may take time. The server reading the client request can timeout if the network is slow, or client request is large (uploading a large payload) or if the client is intentionally slowlorsing, the server can timeout the request in this case. This is often referred to as request read timeout or simply server read timeout. Once the request is read, parsed and understood, the server can either start processing it or place it in a queue and wait for processing. The request can wait in the queue for a while and timesout. This is known as wait timeout. When a request is processing, the server can place a timeout on how long the request can take before it terminates. This is often called processing timeout or usage timeout. Meanwhile the client is also waiting and itself can place a response timeout, if it didn’t receive a response in specific amount of time it gives up on waiting and “cancels” the request, now contrary to common believe as well the request is still processing on the server, canceling a request is a very difficult thing to do without proper setup, configuration and protocol in both client and server and its a whole different topic for discussion. And if the backend is a proxy it becomes both a backend and a frontend and even more timeouts become applicable. Fascinating stuff. — To learn more about backend check out my fundamentals of backend engineering course backend.win

Reading your metrics is a must to monitor your applications and business. What RPM do you have? What is your response time? Is everything okay right now? Metrics have all of these answers. Tomorrow, I will discuss OpenTelemetry Metrics with Golang in my Newsletter. If you are interested in observability and monitoring, this email is for you. You can subscribe to my newsletter using the link. See you in there 👋 firatkomurcu.com

If your application is stateless and the number of Pods during a rolling update isn't critical, I recommend using maxSurge: 1 and maxUnavailable: 0 for smooth, zero-downtime deployments. Here’s how it works: 1) If you have 10 Pods, Kubernetes will create an 11th Pod first. 2) Once the 11th Pod is ready, it will start the 12th Pod while terminating the 10th Pod. This ensures a seamless transition without downtime. #k8s #kubernetes #cloudnative #openshift #docker

Don't write your own custom Health Checks in .NET. ❌ There's a better way. ✅ You can use one of the many existing health check libraries: - SQL Server - RabbitMQ - Postgres - AWS S3 - SignalR - Redis There are many more I didn't mention, but I think you get the idea. I would consider writing a custom health check only if there isn't an existing library I can use. Why would you want to have health checks in the first place? Monitoring the health of our applications is becoming increasingly more complex. So, you want to have a system in place to receive quick feedback on your application health. That's where health checks come in. Here's how to get started with Health Checks in .NET: https://lnkd.in/ejrsJmK4 Are you using health checks in your applications?
