Are there any #informationarchitects or #ux designers in my network here that could consult with me on improving the IA of the Node.js Learn section? At the recent Collab Summit in Dublin, we discussed the need to refactor our linear journey. Matteo Collina got the ball rolling, which we are tracking at https://lnkd.in/g4UhiMVV My instincts as an once-proficient-now-amateur UX practitioner are as follows: - inventory the content - think through a card sort strategy, from maintainers, BUT ALSO, users - re-org easy wins - identify gaps, breakout issues - recruit writers to help fill in gaps - testing??? This is another great example of the multi-disciplinary work an open source project benefits from. It's not all code, and never was, as we have grown and found each other. https://lnkd.in/gNPUEVDB tries to make a strong case for this, and it's been fun to reflect on how to embody it. #opensource #nodejs #contentdesign #technicalwriting

Should you have a separate domain model (and events in EDA) for "draft mode" and "validated mode" or reuse one model for both scenarios? This has been one of the interesting architectural themes I've been observing a team exploring at PayFit France over the last couple of weeks. Draft mode is typically about gathering information. At this stage it may be partially complete and generally in some kind of "invalid" state that prevents proceeding to the next stage of a business process. Validated mode is when the data must always be valid. E.g. all required fields are present, in the correct format, and according to business/domain rules. Typically I would recommend having two separate models* to address the different stages. Even if many of the fields exist in both models, each model will be simpler and there will be less risk of introducing more subtle bugs. If you're interested in these kinds of topics then check out the works of Cyrille Martraire and Alberto Brandolini who have been talking about these ideas for over a decade. *could be part of the same subdomain/context but separate objects at least) #domainDrivenDesign #ddd #ddDesign #softwareArchitecture #domainModeling - https://lnkd.in/egM6Bgt7 - https://lnkd.in/etEXdFWK

Test Driven Development & Developer Advocacy - Interview With Guilherme Ferreira You're not a real developer unless you do TDD. Gui Ferreira is a TDD expert -- but no, not even he would tell you this. In our chat together, we covered a lot of ground. It was great to sit down with a fellow Dometrain course author to go over: - His career journey - Developer advocacy - Test-driven development - And MUCH more! Huge thanks to Gui for the talk, and I'd love to do more in the future! 👇Check the comments for the video link!👇

Presently building a version of Redis with Javascript with the good people at CodeCrafters.io (YC S22), so naturally i am knees deep in Redis docs. As a technical developer relations leader, its important that i, once in a while, take on ambitious software projects and see them through to the end. It gives a refreshed clarity on what technical staff expect to see when they use my products in the web3 space and what engineers expect to see in the docs. And who knows, maybe its time we decentralise Redis too. What do you think? https://lnkd.in/dAF5u4Xp

🚀 Just published another CLI-focused article in my Tinybird DevEx series! 💥 This time I am talking about fun times with your own data repopulation nuclear launch system, but with enough safety measures to make even the most paranoid engineer sleep better at night (well, unless you're like me 🧛). And yes, it's a rainbow full of colors because good looking tools are just better tools! Also, because... why not? 🎨 It's a tool I built for those "I need a fresh start" moments in your Tinybird development. You know, when you are neck-deep in pipeline changes and realize there's no way back? Yeah, that kind. Go ahead and take it up for a spin: https://lnkd.in/eHSKRQWR P.S. Don't worry, no data sources were harmed during the making of this article! Next Up: Time to wrap up CLI tools and dive into some serious stuff! "Beyond DynamoDB Query Boundaries 🔐 How to Set Your Data Free 💥 with Tinybird" is coming next - stay tuned! #Tinybird #DataEngineering #DevTools #Analytics

Feedback loops - cognitive load - flow state. This is my favorite part of how to think about developer productivity. Laura Tacho has provided a fabulous guide on how to think about up-leveling your team. It is about the developer experience but also with quantifiable measures. This guide provides more color on the multiple dimensions you need to consider for making your teams more effective and realizing that there is no one-size-fits-all measure or solution.

Some conversations here about tools and technologies seems a bit short term to me. A couple of years ago people would complain about GraphQL (there's a bigger reason why the sudden hype against GraphQL started, but I'll won't cover it today...) A popular point was around GraphQL Codegen as being hard to setup and slow. But at The Guild Software we think long term... Since than, GraphQL Codegen been worked on and improved daily (continuously for almost 10 years now....) Presets for client and server were introduced to make it extremely easy to setup. And with the latest release by Eddy Nguyen, the new server present is now: * ~50% faster in medium-large codebases * Supports Apollo Federation much better My ask of you all is to keep bringing us real feedback If you say GraphQL is bad/hard - tell us exactly why, and please make sure you use the latest and greatest of our tools before you do....

I found that in startup environments it wasn't about "getting something out the door" being more important than it functioning correctly (testing being the cheapest way of ensuring software works). Instead, many startups hire people who don't have the skills for the roles they are in, and also don't provide mentors who could help them build those skills. And rather than admit that's because the startup is cheap & its not those people's fault when they aren't able to accomplish things like "writing reliable software", the culture gaslights developers by telling them that if only they were smart enough, it wouldn't matter that they haven't been taught how to build software well. For skilled developers, classical TDD is faster than the alternatives: I write far fewer tests with TDD than testing afterwards, for the same confidence in my code. However, TDD requires skilled design. Trying to TDD without being comfortable with encapsulation, domain language, modularity and slicing is like trying to do a double-double beam dismount without being able to do a handstand. Starting by writing the tests second is a great way to learn to write tests. Then you can try TDD again, and see which other skills are making it hard.

I just wanted to mention the release of clj-uuid 0.2.0 with support for RFC-9562 https://lnkd.in/eKgiTtvP which updates the older RFC-4122 with new features and recommendations. What does this mean to you? Primarily, this means support for two new UUID types: v6 — a fast, time-encoding, lexically sortable, unique identifier. This is a field-compatible version of v1, reordered for improved DB locality. v7 — unix time-encoding, lexically sortable, index-friendly UUID with randomized monotonic counter, and cryptographically secure random portion. As such, creation of v7 UUIDs may be slower, but have improved entropy characteristics compared to v1 or v6 UUIDs. This release is fully backward compatible with also some improvements and bug fixes, so I’d recommend all users upgrade to [danlentz/clj-uuid “0.2.0”] If interested, please read on at https://lnkd.in/ejDar5zn #clojure #uuid #rfc-9562

Great talk by 🦁 Luciano Mammino about writing Lambda Functions in Rust. I strongly believe there is a good future for Rust, and it's good to see it working in Lambda too! Also I just learned Luciano and James Eastham are writing a book on it!

I was recently interviewed by Frank Delporte. Frank is a reference in the Java world. He’s a book author with a vast and recognized professional experience in the Java space. Besides that, he’s now also a brilliant reporter/writer for the well know Friends of OpenJDK (Foojay.io) site. In this video I talk about and show some of my recent work (the work I can and am allowed to share). A huge shout out and thanks to Frank for being an extraordinary host! 🙌 #Java #JavaFX #openjdk #openjfx

I discovered an exciting question on Twitter that relates to a professional domain (authentication) with which I have extensively engaged and also has strong implications for software architectures. Since I don’t want to pay for Twitter Premium, elaborating in detail on Twitter was difficult, so I wrote about it on medium. The question in brief: Why do we actually need refresh tokens? Here is my answer to the question. I would be very happy to receive feedback and discussions about it. Even if the topic deters many people, authentication is an absolutely fascinating subject area. https://lnkd.in/eqQsSffc
