Give Rails a chance, or if not, at least watch DHH's highly entertaining and inspiring RailsWorld keynote about Rails 8, especially if you are in the web development business. The sentiments about simplicity and developer empowerment really resonated with me. Even if you don't adopt Rails, it seems important to question assumptions about what modern web development is, whether it needs to be so complicated, and what effect that has on business. I'm excited to build something again...with Rails. https://lnkd.in/ggkYzjhe

Challenges with Storyblok in dev teams? This is how we guide you through. We work closely with development teams and get deep insights into their specific challenges with Storyblok. Even experienced developers sometimes encounter obstacles they can't overcome by themselves, which can raise doubts about Storyblok as a CMS. Here’s our process when developers approach us for assistance: 👉 We actively listen to understand the developers' issues so we can address them effectively. 👉 Then we provide tailored guidance to help developers to solve and overcome these challenges. 👉 We organize weekly calls to continually refine the developers use the platform and to fasten their technical growth. This approach ensures that all team members can use Storyblok efficiently and reliably. What challenges with Storyblok have you faced?

Yes, I'm certainly not a fan of web apps and certainly not of hybrid apps. However, we live in a time where this type of software development for mobile applications is becoming increasingly important in order to reduce costs or reuse existing (web dev) knowledge. That's why I can only congratulate Gerald Versluis (and others) on this really great workshop. With Blazor Hybrid, we native developers can at least get around JavaScript and have all the niceties that the .NET ecosystem brings us in conjunction with C# and Blazor Pages. Chapo for this workshop! #dotnet #csharp #dotnetmaui #maui

Over the past few months I’ve written an extensive tutorial on how to build software applications with Node.js and React. I’m sorry to tell you that this experience didn’t teach me anything about B2B sales, though. But hopefully, it’s still useful for some people out there. From the introduction: The approach of this tutorial is to teach its readers how to build a fully working software application from zero to production. This means two things: 1. You are not required to have done any kind of software development before getting started with this tutorial. It will introduce and explain everything that is needed to build applications in full detail, assuming no prior knowledge or experience. This is the “from zero” part. 2. Building on the foundational knowledge it teaches in the first half, the tutorial will then, step by step, guide you through the process of building a real, full-fledged, and completely working software application, again explaining every detail along the way, and shows how to “deploy” that application — that is, how to make that application available on the Internet for anyone to use. This is the “to production” part. Speaking of B2B sales: I’m afraid you cannot buy this tutorial. That’s because I’m making it available for free, as a series of posts on my blog. The first three parts are already published: https://lnkd.in/e2XCYm3p https://lnkd.in/eW7wUc_d https://lnkd.in/eAU6kgH9 No, you do not need to sign up to my newsletter to get access to the tutorial. That’s mainly because I don’t have a newsletter. Also, no need to follow me (although admittedly, it might help to get you notified whenever I’m publishing a new chapter). Furthermore, please don’t be disappointed if clicking on the tutorial links won’t present you with a cookie banner. That’s because my blog doesn’t use any cookies. No, not even those from Google Analytics, as I’m not using that either. This means I will have no idea how many people will read the tutorial — which makes sense because let’s face it, who is going to consume this kind of long-form, deep-dive technical content nowadays anyway. And in text-only form, of all things! Should you nevertheless decide to dive into the text, expect to learn how to program using JavaScript and TypeScript, how to use these languages to build rock-stable backend applications with Node.js as well as elegant frontend applications with React and Redux, and finally, how publish a complete and integrated software solution on Amazon AWS. Ok, that’s it. If you want to access the bonus chapters, simply subscribe to… — just kidding. There are no bonus chapters. Everything you need to learn to build useful software products is right in the… normal chapters, I guess? Happy reading!

Back to Rust for Heimdahl.xyz's Solana integration 🛠️ After some side projects, finally putting Rust into real production. Two key reasons: 1. Solana's official SDK - no compromises with third-party libs 2. Rich ecosystem of Rust code to adapt and build upon The compiler's strictness makes perfect sense when you're building infrastructure that has to just work. Successfully streaming Solana events through the same WebSocket as EVM chains. Clean architecture paying off - new chains shouldn't mean new complexity. Next up: Cross-chain USDT flows tracking. One API to track them all. Try it out: https://lnkd.in/dF8T7jqQ Website: https://heimdahl.xyz p.s. When the Rust compiler approves your code, you know it means business. #RustLang #Solana #Infrastructure

Wrapping up an amazing 10 days in Berlin, running Design Sprints with a super cool startup in the dev tools space. So much good energy. So much fun. Quite often when folks think Design Sprints, they imagine consumer apps or B2B SaaS products. Can Design Sprints also work with potentially complex developer tools and services? Absolutely. In fact, I can’t imagine going at it any other way. Having helped create many dev tools, services, and platforms over the years, I’ve seen first-hand time and time again how easy it is to get stuck building for months on end, only to learn (surprise!) that a team built the wrong thing, built too much, shipped too late, or just couldn’t get off the launchpad. Design Sprints break this cycle by putting your big ideas in contact with reality in just 4-5 days. The format forces a level of brevity and clarity that lets the core essence of those big ideas really take center stage. Most importantly, it helps teams learn and refine their thinking quickly based on direct insights from their target users. If the cost of running a Design Sprint is less than the cost of being wrong about a big bet, then it’s time to sprint.

WTF Google? Aren't you "all-in" when it comes to making PWA discovery and installation easier? 90% of all apps in the app stores could have been a PWA, but it doesn't help if you make decisions like this in the Chrome UI. Please turn back this idiotic decision to have "Install Page as App" & "Install <app-name>" sit under "Cast, save and share" 🤯🤬😱!!! Agree? #pwa #freethepwa #whoneedsgatekeepers #chrome #webapp

Nobody wants to spend +𝟭𝟬𝟬𝗸 𝗼𝗻 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿𝘀. But many do and 𝘀𝗶𝗴𝗻𝗶𝗳𝗶𝗰𝗮𝗻𝘁𝗹𝘆 𝗼𝘃𝗲𝗿𝗽𝗮𝘆𝗶𝗻𝗴 𝘁𝗵𝗲 𝗮𝗴𝗲𝗻𝗰𝘆 they hired. It's not because the developers they hired were necessarily inexperienced. But the process and pricing were simply off. Many are aware of the downfall of hourly pricing - and ask for fixed pricing. Which is not much better if done poorly. Check this blog post if you want to build software with a tighter budget and still get what you want. We are expensive at first, but only because we save you much more than you spend. Pricing software projects the right way: https://lnkd.in/dQfPwm5P

I put together an open list of official and unofficial LLM-based chatbots related to Swiss government agencies. The hype may have calmed down a little; nevertheless, more and more are and will be popping up in the near future. Therefore, I compiled a list of LLM-based Swiss government-related chatbots known to us. https://lnkd.in/eAZJN6Hj It's obviously heavily dominated by our own unofficial projects, but we'd love to add bots made by others, too. Write a comment or a Github issue if you know of more. Some of the chatbots on that list were actually never publicly announced. For example, the one about the Canton of Zurich.

I added a new confluence page to our internal dev guide this weekend. The topic -> "Patterns & Anti-Patterns in Ruby on Rails." The best part: it was the output of a 35-minute conversation I had with the new advanced voice chat in ChatGPT. I had some time in the car by myself this weekend, so I fired up a new conversation with ChatGPT. We spoke through patterns. I spoke about some of the issues & opportunities I'm seeing in our codebase. I ended up with a clean and concise list of good architectural patterns and anti-patterns to avoid. The new "advanced voice mode" isn't all that great, in my opinion. Interrupting it was still awkward. But it's getting better every month. And even though there are issues, I can't imagine having a conversation like I just did a few years ago. Have you had a good conversation with AI about coding & dev leadership?

🔒 Securing Your Symfony Applications with Nelmio Security Bundle 🛡️ In light of the recent surge in hack attempts targeting web applications, it's crucial to fortify your Symfony stack with robust security measures. If you haven't already, I highly recommend integrating the Nelmio Security Bundle into your Symfony projects. The Nelmio Security Bundle is a powerful tool that enhances the security of your Symfony applications by providing a set of advanced features and best practices. Here's why it's a must-have in your development arsenal: 📝 Content Security Policy (CSP) Configuration Define strict CSP rules to prevent cross-site scripting (XSS) and other injection attacks. Fine-tune your CSP settings to allow only trusted sources and protect against malicious code execution. 🕵️‍♀️ Forced HTTPS and Strict Transport Security Enforce HTTPS connections to encrypt data transmitted between the server and clients. Implement HTTP Strict Transport Security (HSTS) to ensure all communications are securely encrypted. 🎭 Clickjacking Protection Defend against clickjacking attacks by controlling frame embedding and preventing unauthorized access. Customize X-Frame-Options and Content-Security-Policy headers to safeguard your application. 🔍 Referrer Policy Configuration Control the amount of information sent in the Referer header to protect user privacy. Prevent leaking sensitive data and reduce the risk of referrer-based attacks. 🧩 Integration with Symfony's Security System Seamlessly integrate with Symfony's built-in security system for a cohesive security solution. Leverage Symfony's authentication and authorization mechanisms alongside Nelmio's additional security features. Installing and configuring the Nelmio Security Bundle is straightforward, and the benefits it provides are invaluable. By incorporating this bundle into your Symfony stack, you can significantly enhance the security posture of your applications and protect against common web vulnerabilities. Don't wait until it's too late! Prioritize the security of your Symfony projects and give the Nelmio Security Bundle a try. Your users will thank you for the added peace of mind. 😊 🔗 Learn more about the Nelmio Security Bundle: https://lnkd.in/dE2FBshp #PHP #Symfony #WebSecurity #ApplicationSecurity #NelmioSecurityBundle

It seems some developers still need a reminder: preloading responsive images before defining the viewport can lead to costly mistakes. Here’s what happens: without a defined viewport, mobile browsers often download large.jpg immediately upon encountering the preload directive in the <head>. Then, when they encounter the viewport definition ON THE NEXT LINE small.jpg gets queued for downloaded too. This will cause 2 image to compete for early resources. Not a huge problem for your average desktop but for your worst 15% mobile views it hurts where it counts! For one of my clients, this oversight meant the difference between passing and failing the #CoreWebVitals. Thankfully, I caught it and now we can fix it! A good reminder that even small details in optimization can have a big impact.
