Day 09 of Becoming a Better Engineer! One thing I've realized so far is that being a good problem solver is more about using common sense than relying on fancy technical terms. Let me clarify. Fancy terms like stateful backend, caching with Redis, low latency, network optimization, saving network bandwidth, minimizing server costs, preventing server and database crashes, TCP, UDP, and so on can help in planning a better architecture. However, for a beginner, these terms can be overwhelming. Here's a simple story to explain these concepts that even a 5-year-old can understand. Prerequisites: Common sense Story There is a boy, X (frontend), who has a medical condition that causes him to forget everything once he completes a task. When someone asks him for information, his job is to get it from Y. Y is very busy and can't handle too much pressure; if asked repeatedly, Y might become overwhelmed. The distance between X and Y is 10 km. X has two vehicles: a TCP truck and a UDP bike. If X chooses the truck, he must pack survival essentials, ensuring a safe journey, but it takes time to prepare. In contrast, the UDP bike allows him to travel quickly but without any guarantee of reaching the destination. Suppose X reaches Y, gets the information, and returns home. Since he forgets everything after completing the task, he would need to repeat the whole process if asked for the same information again. This increases time (latency), fuel costs (costing), and disturbs Y unnecessarily. Instead, if X shares the information with his neighbors (browser caching), he can ask them next time instead of repeating the process. This saves time, cost, and energy. Additionally, if the neighbors are unavailable, he could have shared the information with his relatives (server caching). This way, he still travels less and is more efficient than starting from scratch each time. Note: Neighbors are less trustworthy than relatives. Concepts We Learned from This Story: TCP UDP Saving network bandwidth Saving database calls Client-side caching Server-side caching Low latency Saving costs If you find this helpful, please share your thoughts. #Engineering #SoftwareDevelopment #ProblemSolving #CommonSense #TCP #UDP #Caching #NetworkOptimization #CostSaving #LowLatency #BeginnerFriendly #TechStory #SoftwareArchitecture Real engineering is interesting!

🚀 Staggering Insights on the Value of Open Source Software! 🚀 An eye-opening study unveils the immense economic impact of Open Source Software: 1. OSS's Supply vs. Demand Side Value: While the cost to replicate the most popular OSS stands at $4.15 billion, its demand-side value is a staggering $8.8 trillion! This underscores OSS's irreplaceable role in our ecosystem. 2. Language Concentration of Value: The demand-side value is highly concentrated in a few pivotal programming languages (Java, JavaScript, C (including C# and C++), Python, and Typescript). 3. Power of the Few: Just a small fraction of OSS developers (3,000 developers, representing 5%!) are responsible for a lion's share of its supply-side value (93%!). 4. Companies would need to spend 3.5x more on software than they currently do if OSS did not exist. #OpenSourceSoftware #OSS #DevSec #AppSec #OpenSource #DevSecOps #ProductSecurity

Serialization is the process of converting an object into a format that can be transmitted over a network and later reconstructed into the original object. This technique is crucial for data exchange in distributed systems and APIs. - **JSON** is a widely used format for serialization. It is human-readable and easy to use, making it a popular choice for web applications. - **gRPC** offers more advanced features compared to JSON. It uses Protocol Buffers (protobuf) for serialization, which results in smaller payload sizes and reduced latency. - **Interface Definition Language (IDL)** is used to define the structure of the data being serialized, ensuring consistency and compatibility across different systems. In summary, while JSON is great for simple and human-readable data exchange, gRPC with Protocol Buffers provides a more efficient and powerful alternative for high-performance applications. #Serialization #JSON #gRPC #ProtocolBuffers #SoftwareEngineering Note: I am currently looking for job opportunities in software engineering.

I've recently published a new Medium post about handling faults in .NET applications using Polly. Failures in distributed systems are inevitable, whether it's network issues, temporary service outages, or other transient faults. But with the right approach, we can make our applications more resilient and reliable. 💡 In this post, I walk through how to integrate Polly into your projects, with straightforward explanations and simple examples. If you're looking to improve the reliability of your applications, I think you'll find this post helpful. 🚀 Read the full post here. 📖 #dotnet #Polly #WebAPI #SoftwareDevelopment #Resilience #Coding #APIDevelopment #softwareengineering

A week ago, an exception was raised 💣 by one of our microservices. I found this in the logs, reported it to the respective team, and they resolved it. However, the same exception occurred again, but this time it required a different solution. 𝐇𝐚𝐧𝐝𝐥𝐢𝐧𝐠 𝐀𝐏𝐈 𝐂𝐚𝐥𝐥𝐬: 🛡 When calling an API, whether external or an internal microservice, you cannot always expect a response. Therefore, it's essential to use try-catch blocks and set default values. Now comes the main point, 𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐇𝐓𝐓𝐏 𝐑𝐞𝐬𝐩𝐨𝐧𝐬𝐞 𝐂𝐨𝐝𝐞𝐬: 🔍 🛑 503 𝐒𝐞𝐫𝐯𝐢𝐜𝐞 𝐔𝐧𝐚𝐯𝐚𝐢𝐥𝐚𝐛𝐥𝐞 𝐌𝐞𝐚𝐧𝐢𝐧𝐠: The server is currently unable to handle the request due to temporary overloading or maintenance. 𝐂𝐚𝐮𝐬𝐞𝐬: - Server overload - Server maintenance - Temporary server downtime - Too many concurrent requests 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧: Just leave it, try after some time. 🛑 403 𝐅𝐨𝐫𝐛𝐢𝐝𝐝𝐞𝐧 𝐌𝐞𝐚𝐧𝐢𝐧𝐠: The server understands the request but refuses to authorize it. 𝐂𝐚𝐮𝐬𝐞𝐬: - Insufficient permissions - Authentication issues - IP restrictions - Misconfiguration of ports and protocol 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧: Go to the respective team that has ownership of the API and report it. ☑️ CASE 1 (1 Week ago): The scenario was let's say a web server is configured to only allow secure (HTTPS) connections on port 443. If a client attempts to access the server over HTTP on port 80, the server might respond with a 403 Forbidden error. So we fixed it all. ☑️ CASE 2: The scenario was due to overload, just 503 was happening. We did one more try, it was all set. 📝 𝐌𝐨𝐫𝐚𝐥 𝐨𝐟 𝐭𝐡𝐞 𝐬𝐭𝐨𝐫𝐲:  Don’t just glance at errors or exceptions. Read and understand them thoroughly like a watchdog. The compiler is your friend, not your enemy, helping you identify and resolve issues effectively. #techclearance #10xengineers #debugging #softwareengineering #learnalways #followAndLikeForMore
