🚀 Are Microfrontends Overkill for Your Product? Or the Key to Streamlining Development? Microfrontends can sometimes lead to over-engineering, especially if you don’t have a deep understanding of all layers of your product. But here’s the thing: dismissing this technology could mean missing out on its potential. 💡 🔗 Today, tools like Vite, Webpack, and RSPack support module federation, making it easier than ever to integrate microfrontends seamlessly. 🛠 Maybe it's time to rethink how these innovations could optimize your software development pipeline and boost productivity. 💻✨ #Microfrontends #SoftwareDevelopment #TechInnovation #ModuleFederation #DevOps

🔍 A Technical Observation from Yesterday's El Clásico Streaming Experience As a frontend developer, I couldn't help but notice some interesting technical aspects during yesterday's highly anticipated Real Madrid vs Barcelona match. The streaming service experienced significant authentication challenges during peak user load, highlighting crucial lessons about scaling and security in web applications. Key Technical Observations: • The sudden implementation of authentication walls must be accompanied by proper infrastructure scaling. I bypassed their authentication with a simple toggle in the value stored in local storage. • User experience is paramount - delays in authentication can significantly impact viewer satisfaction • Client-side state management requires robust security measures beyond basic localStorage implementation This experience reinforces important principles for web developers: 1. Always anticipate and plan for traffic spikes during high-demand events 2. Implement robust authentication systems that can handle concurrent user loads 3. Never compromise on security best practices, even under pressure to deliver P.S. What an incredible match it turned out to be! 🔵🔴 #WebDevelopment #TechLessons #UserExperience #WebSecurity #SoftwareEngineering #ElClasico #Frontend

I completed the fourth module (UI + Presentation) of the iOS Lead Essentials program 🥳! Here's a summary of what I learned so far 👇 - The fundamentals of good system design and architecture. How to think, design, and draw diagrams like a software architect. - Networking best practices to develop, maintain, and test a clean networking layer in iOS apps with key frameworks such as URLSession, URLProtocol, Decodable, and third-party code. Also, how to work effectively with backend teams. - Persistence best practices to effectively develop, maintain, and test a clean persistence layer in iOS apps using URLCache, CoreData, FileManager, Codable, and other key persistence frameworks. - UI, UX, and Presentation best practices, and how to develop, maintain, and test a clean UI and Presentation layer in iOS apps. How to use MVC, MVVM, MVP, and their variants, prototyping techniques, localizing apps, working effectively with designers, and how to create reusable UI/Presentation components.

I'm sharing this technical article I wrote about asynchronous functions in JavaScript and, above all, when to use return await vs. return and why!.

Hi! I'd like to share today some hints about a very importante feature on OO languages, on that case, in JAVA... Inheritance. Understand this feature is the base for OO languages and know how to handle different cases is so powerfull to improve our deliverys everyday. Hope this article keep helping our community. https://lnkd.in/eMZ-pynV

Are you ready for Valencia Codes Level Up #17? This time we're going to go deep on Elixir and Erlang with two great talks that will bring you up to speed with these very popular and exciting languages. Introduction to Elixir: Modern Language and Concurrency by Jeremies Pérez Morata, Developer @ Ufirst Group Elixir is a functional and concurrent programming language that is becoming a crucial tool for developing scalable and distributed applications. This introductory talk will cover the fundamental concepts of Elixir, its clear and efficient syntax, and its integration with the Erlang virtual machine, which enables optimal concurrency management. This session is intended for developers of all levels who are interested in enhancing their skills and exploring advanced technologies in high-availability systems. Join us to understand why Elixir is gaining recognition in the tech community. Building Network-Distributed Systems with Erlang Ilya Ashchepkov, Software Engineering Lead @ Velvetech Erlang is a powerful programming language known for its robustness in creating fault-tolerant, distributed systems (like WhatsApp!). In this hands-on, semi-live session, you'll learn how to build a network-distributed system using pure Erlang/OTP, focusing on a practical example: calculating factorials. This session will cover essential concepts of Erlang's lightweight process architecture and its capabilities for building scalable systems. Agenda 1900 - Snacks 🍕, Drinks 🍻 and networking 1930 - Talk "Introduction to Elixir: Modern Language and Concurrency" 2015 - Talk "Building network-distributed systems with Erlang" 2100 - Go to a bar next door to continue networking! Join us on October 2nd by signing up here 👇 https://lnkd.in/dTjqKxuN

Warning: This is a very opinionated blog post. I would love to hear what y'all thoughts are and if my prediction makes sense. Very short read... https://lnkd.in/ejKbrwFq

After a well deserved break, I'm so excited to get back to As ANY live episodes with my dear Josefine Schaefer tomorrow! 🎉 It's time to wrap up the year of learning by reviewing what others have shared. It never hurts to do a recap of everything that has happened in the web ecosystem 🤓. The usual stuff, plus the new one that has been coming out, summarized in the famous “State of <X>” reports. Join us if you want to spend some time exploring the results of #StateOfCSS, #StateOfFrontend, and more 💡

Big thanks to my awesome teammate Andrés Gutiérrez Ramírez for introducing me to "Agile Technical Practices Distilled" by Pedro Santos! / Marco Consolaro 📚✨ https://lnkd.in/dyPGcdd3 It's been a long time since a tech book has captivated me this much! For anyone looking to boost their technical skills and embrace agile methodologies, this book is a must-read. Let's keep growing together! 🚀👏 #Agile #TechnicalPractices #Teamwork #ContinuousLearning #BookRecommendation

Everyone needs clean code, but not everyone has to do it the same way, and not everyone needs to do it the same way. In software development, you have to know how to differentiate the "what" from the "how." One principle above "clean code" is: engineering is a compromise. You always have to compromise on one point and sacrifice another. But you always have to compromise on your goals. The mistake of #CleanCode is not the "what" everyone wants, but the "how" to achieve it, partly by ignoring the abstractness of the concept of "clean code," the subjectivity of the reader, and the relativity of the context. The "how" must always be subordinated to the "what", in this case, a clean code will be dirty if it interferes with its objectives.

👀 Did someone say open governance should have an open roadmap? 🎉 https://lnkd.in/eBwdGEu4 🎉 Our first roadmap has been approved by the TSC and formally published! Early in our project, it was important to set our community up for success: copying HashiCorp Vault (for better or worse) was not a viable strategy to build a sustainable community and especially a fork. There simply aren't enough hours in the day to continually do clean-room reimplementations of proprietary features... We'd always be playing catch up. Thus we opted to differentiate ourselves in a key way: listen to the community. Many of the features on our roadmap are things that the community has publicly asked for on the upstream issue tracker and been ignored, time and time again. Paginated lists, because the UI hangs on KV or PKI mounts with lots of entries. Transactional storage, because networking isn't always reliable or timeouts may happen and changes should be rolled back, not left in a random state. PKCS#11 support in OSS editions because, frankly, it is 2024 and strong security is a basic necessity for everyone when running a secrets manager. Improving the mount table limit, because there are times when ~14k secrets engines just aren't enough. The list goes on. Our roadmap seeks to prioritize a few key areas where we think we can make improvements: in safety, in scalability, and in building a community around OpenBao. So check out our roadmap! If there's something that interests you and you wish to contribute, we're happy to work with you!
