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!

I'm very interested in how companies manage to combine business and open source, and this interest has grown since I joined Storyblok. At Storyblok we have an entire team dedicated to open source SDKs, and most of the engineers who build our headless CMS also contribute and maintain our packages. This costs money, of course, and comes with other problems, such as having to maintain not just one product, but a collection of tools exposed to the public, each potentially with its own set of problems and maintenance overhead. Why do we do this? This is not an easy question, and I think many companies and individuals can answer it in different ways. My entire career has been built on open source, so I know many of its benefits, but for a company it's different, and I'm starting to find some interesting answers. For starters, open sourcing our SDKs and tools promotes transparency, allowing developers to understand and trust our integrations. It also fosters innovation through collaboration, leveraging the collective expertise of the global developer community. This accelerates problem solving and creates valuable learning resources for developers at all levels. And engineers are happier when they contribute to open source, which is no small thing. I'm curious, what are your thoughts on the role of open source in business? I will continue my exploration... #opensource #business

Often my employees and I need a development environment for C++ together with the installed GRPC. To reduce the time for installing and deploying the environment, I started making Dev Containers, which I give to my employees and they run them in VSCode. I hope it will be useful to someone else. https://lnkd.in/dCCQBpTt #cpp #c++ #docker #devcontainers

Imagine getting a whopping 𝟕𝟓% discount offer! 😲💰 Just the other day, I sat down with a client over coffee in Duisburg. They had software development needs that typically would cost around $𝟏𝟐𝐊 with experienced developers from a German company. However, after some careful analysis, I was able to estimate the project at only $𝟑-𝟒𝐊. How did I pull off such massive savings? Well, it's all about the power of Right Outsourcing! By tapping into the talent pool of South Asian professionals, we're able to offer top-notch services at a fraction of the cost. ✨ With lower living expenses in countries like India and Pakistan, we can pass on those savings to our clients, slashing expenses by 𝟔𝟔.𝟔𝟕% 𝐭𝐨 𝟕𝟓%. But it's not just about the savings - it's about quality too! 🌟 Remote workers from these areas bring a wealth of skill and expertise to the table. And with Right Outsourcing handling all the management and recruiting tasks, clients in Europe can relax knowing their project is in good hands. 🔒💼 Ready to experience high-quality work at an unbeatable price? Send me a DM, and let's chat! #RightOutsourcing #Quality #AffordablePrice

Feedback: Not just a cool effect for punk music in the 80's! I rely heavily on #feedback in so many things in my life: Is my heart rate right? Is my #code passing the tests? Is my bicep getting bigger?(yes, obviously) Even as I type this the browser gives me feedback that obviously was spelled wrong... But what happens when feedback isn't obvious. The other morning while running my watch wasn't tracking my heart rate properly. This was fine for me because I could feel by my breath and pace that I was still meeting my goals. Sometimes though, thinking someone is aware of their performance isn't enough. As a high school administrator I remember once walking into a classroom and seeing the front tow rows engaged in what the teacher was doing and the back three were on their phones, chatting, sleeping, doodling, basically all the things I used to do when I was in high school (my phone had a really long cord.) In my mind I thought it was obvious that the #teacher wasn't meeting the standard of getting everyone engaged and that the teacher would know that the conversations and laughter from the back of the class was distracting to those that wanted to understand the lesson. To my surprise when I asked him how he thought the observation went he was pleased that he got 20% of the students engaged and thought it went well. When I reminded him that this was well below the standard he was upset and a little angry. And to be fair it is difficult in the modern day to keep kids engaged. Also though, once he was made completely aware that he wasn't meeting the standard he sought out help on things he could do to increase engagement and work on some classroom management strategies as well. I could have just left the room, assumed that he knew his performance wasn't good, I mean, it was written down that 80% of the class would be engaged 80% of the time... But, sometimes overt tough conversations have to happen to get folks to realize that they need to improve to meet standards. In my favorite podcast, "Coaching for Leaders" with Dave Stachowiak it was mentioned that criticism is investment. If my manager gives me a critique, even if or maybe especially if it's not positive I feel like he is investing in my future. He is tough on me because he wants me to be the best me that I can. He could sit back and assume I know if I'm not meeting the standard, and he would continue to get the same performance from me. But he knows I want to do a good job so he is overt when I could do better. He does deliver the message with kindness and encouragement of course which made it much more palatable, but the message still came accross. Bottom line, if you want improvement in #performance don't assume anything, provide the tough feedback and form a pathway towards #growth! Thanks for reading y'all and remember the ABCs of coding Always Be Coding and sometimes Always Be Critical (and kind).

My time as a Software Developer at Integral GmbH was an incredible journey of growth, both technically and personally. Working remotely for the entire placement had its share of pros and cons, and it really opened my eyes to new ways of thinking and working. 💡 The Non-Technical Learning: One of the biggest non technical lessons I took away is in communication. Working entirely online forced me to refine how I present myself in virtual spaces. Learning how to communicate and deliver ideas effectively through screens was challenging but rewarding. It pushed me to adapt, find clarity in my messages, and develop new ways to engage with teammates spread across different lands. Overall, I’m grateful for the experience and for the chance to grow both professionally and personally. Remote work may come with its hurdles, but it also provides opportunities to develop resilience and adapt to new ways of working.

Open source is eating the world. I wanted to find out what German R&D powerhouses contribute to the movement. Here is what I found by browsing around in Github:   I used a very simple methodology and just tried to find the repo with most stars for each company. As many repos are hosted by specific departments or labs, the list might not be completely accurate. Here are the results (more details in the slideshow): 1️⃣ Cariad/VW: 6 stars 2️⃣ Bosch: 380 stars 3️⃣ Mercedes-Benz: 255 stars 4️⃣ SAP: 2900 stars   🤔   This perspective oversimplifies things: Github stars are a vanity metric, there are many more ways to contribute to FOSS than owning repos and very successful projects might have already been moved to an independent organization such as Apache. But: I think the result is still devastating ‼️ My intention is not to point any fingers. I know from experience that it can be difficult to make the business economics work in the short term. I just think the issue is worth discussing and FOSS is a critical factor in today’s competitive landscape. There are so many advantages of open source, especially for larger organizations: 1️⃣ No vendor lock-in, especially with regards to cloud services 2️⃣ Better efficiency and security than custom solutions 3️⃣ Collaboration opportunities with startups and academia   So, please help me: Which open source success stories from large German corporates do you know (can be collaborations with startups / academia)? What do we have to do to get more of them?   Very much looking forward to learning what’s your perspective on this 👇in the comments ☕during a virtual coffee talk: https://lnkd.in/gjX6tzXJ #opensource #foss #industrialai

Systems > SMART goals - especially in software development In April, I participated in the Berlin company run for the second time. So I was interested to see how I did compared to last year. I don't use Strava or heart rate monitors much, so I didn't know what to expect. Still, I was pretty sure I could beat last year's performance. That's because I've been doing a variety of workouts 5 times a week for the past few months. 📌 Set up a good system and the score takes care of itself The same goes for software development. If you want to increase your test coverage, start pair or ensemble programming on tests. If you want to get better at public speaking, find ways to practice in meetups and team all-hands. If you want to make progress on your project, start with a workshop and have regular discussions on Slack and in meetings. SMART goals makes sense when you have predictable processes. I don't find that useful in software development or in my personal life. And not motivating either.

The benefits of AI code assistants are still being evaluated, but here at Deutsche Telekom we are confident that our AI strategy to continually assess COTS products, as well as developing our own products and data foundation is the right approach to yield benefits in the future. Have a look at the post below from one of our leading developers on the topic It’s exciting to think about the capabilities of the product in only a few years from now; perhaps covering all aspects of the SDLC and integration to user stories, more context in relation to existing code repos throughout the enterprise (particularly useful for very large enterprises), models optimized for dialects of the languages (GoogleSQL vs PostgreSQL etc)….to think of a few examples Regardless, the developer experience will be greatly enhanced in the next few years and at Deutsche Telekom we’ve got a front row seat! 👏
