I've been giving talks about tech since 2016. My first talk was about docker at @ebay in Aarhus (Den blå avis) together with Johan Abildskov. I think it was his first public talk as well (correct me if i'm wrong Johan) and i was super nervous. There were 16 people in the room ! It was a great experience. Since then I started to give talks at meetups and eventually at conferences. I've organized Docker birthday events, Cloud Native events and a small conference as well. And i love being able to give back to the community that gave me so much. A small hint if you want to give talks. Keep your slides simple. When you feel they are to simple, make them even simpler. Managing time is difficult on stage, so the more information the audience sees, the more they see you miss or skip. Take this picture of a mailbox. You can talk for 2 min or 15 min about coupling/decoupling in software from that one picture, and people will listen to you instead of reading text. Maybe add a headline "Let's talk about coupling". It's much easier to manage time from a slide like this, and to tell a good story. See you at Kubernetes Community Days (KCD) Denmark where Ophelia Zhang Dalsgaard and I will talk about Developer Experience ?

Sustainability in my professional life. Part 4: The Fellowship of Green Software (continuation from previous post) So, what happened after Hans-Jürgen and I had agreed to put Green Software on our agenda for the Backend Onsite? We used the Open Space format for our onsite, and I hosted the session on Green Software. I shared what I had learned so far (which honestly did not seem a lot), and then we started discussing and collecting ideas. I had not expected that so many developers would be interested in the topic, and again I was amazed by the amount of ideas that they brainstormed. And this time we did not get stuck afterwards. Green Software became a recurring topic in our future onsites, and also spread into the organization. Over the years, Hans-Jürgen had built a great network within the company, and he used it to get in touch with the Sustainability Management and look for other people who wanted to contribute to making the organization even more sustainable. In the meantime, my engagement as an external Scrum Master with the company has come to an end, but Hans-Jürgen and the developers are still working on Green Software and making good progress. For example, one of the developers has presented the concept of Green Software in a department townhall and they are exploring the Azure Emissions Dashboard to measure the footprint of their software. I am deeply grateful that I could be a part of this movement, and it makes me incredibly happy that it is still growing after I left the project. Thank you, guys! Without your energy and your drive to find solutions, we would not have come very far. I am honored to have walked this path with you, and curious what will come next. And I will always feel connected to you wonderful people, even though I’m not part of the team anymore. After all, we are still in the Fellowship of Green Software together…   When did you become part of a movement? How do you feel about it today? Let me know in the comments. #networking #sustainability #software

Have you tried MVW pattern in your apps? Model - View - Whatever? Jonas Uekötter was recently featured on Sean Allen's Swift news for the month of April. In his twitter thread he points out that when choosing a pattern, the real issues often stem from overcomplicating things. This is a refreshing reminder for us all: - Keep it simple - Understand your goals - Use tools that suit your team Have you ever felt overwhelmed by the many ways to structure app development? What's your approach to choosing development frameworks and patterns? #MobileApp #Architecture #iOS #Swift #Apple #Google #MobileAppDevelopment #Flutter

Bluesky is a Twitter-alternative. It launched two years ago, and has already grown to an impressive 5.5 million registered users: with only ~10 developers building it. But how was it built? With Elin Nilsson we spent the last couple of weeks talking with Paul Frazee and Daniel Holmgren (two founding engineers at the startup) to get a sense of how this platform went from zero to where it is today. A few interesting notes: - The core of the protocol and app were built by 2-3 engineers over 9 months - Bluesky moved from AWS to on-prem for cost-saving and performance reasons - The team migrated from PostgreSQL to... SQLLite! For maintainability and performance reasons. And they are very happy with this move. Read the details in today's free deepdive: https://lnkd.in/ezqHQvND

I made it, yay! 🎉🙌 🖇 I have successfully merged my branch with my case study from Mimbly into the main branch. ...For those of you who aren't coders, this means I have a new case study up in my portfolio at kajsatunius.se✨ After reading up on Git in cmd in the terminal and thanks to all your help here on my LinkedIn post, I now understand Git commands a little better. 🖥️💡 Merging a branch with main might not sound like much (but last time was a mess due to merge conflicts 😅 ), but my deeper understanding will result in fewer errors in the future. Soooo, THANK YOU 🙏 ----------------------------------------------------------------------- The case study is from my time as a UX designer at Mimbly and reflects my journey as I single-handedly lead the UX process. This included: ✅ Strategic/project planning in Jira ✅ Implementing a design system ✅ 8 internal interviews ✅ Research planning (goals, interview guide) ✅ Metrics setup/OKR and KPI (Matomo) ✅ 15 external interviews ✅ Mapping interview findings in FigJam ✅ Conducting a research workshop ✅ Creating wireframes ✅ Compiling an Excel report ✅ Prototype testing and analysis (metrics etc) ✅ Conducting accessibility tests Thanks to everyone at Mimbly for providing such an awesome learning space! Special thanks to Isabella Palmgren and Emil Vestman for giving me the chance to prove myself, and to Ash Malmsten for the invaluable developer insights. 💖👏 #UXDesign #CareerGrowth #Portfolio

One of the highlights for me this past year has been the partnership with TeamPilot.io. John Cannerborg and the team have many years of experience in matching freelancers with companies. And now I have a way of actually helping my big network of independent contractors looking for their next gig. It's not a secret that the platform hasn't been full of assignments lately. The market has been dryer than anything I've experienced before. But there are signs of a comeback. And last week we went live with a project where we are looking for 6 remote fullstack developers for a customer. 🤩 (We can't handle anymore applicants for that assignment now though.😅) Hopefully this is just the beginning! It's great to see that there are so many candidates who have registered a profile on TeamPilot. And we love talking to new and existing customers about upcoming projects. But isn't it a bit boring only doing so online? We think so (even though we are remote-first) and have something exciting planned in Gothenburg to kickstart the fall. So please mark your calendar if you're a freelancing developer or if you're a stakeholder in a tech company who would need a few extra hands in your team. "But we never hire consultants here. It's expensive and they are not committed." Well, we have invited my good friend and experienced CTO Adam Horner to bust that and some other common myths about contractors. Adam will also share his thoughts on when you shouldn't hire a consultant, and when it's actually a really good idea. At least if you want to save both time and money. So... Are you a freelancer? Or a CTO (or similar) in a growing company? Please join us for this social event at OGBG, Skeppsbroplatsen 1, Gothenburg. August 28, 17-19 Send me a dm if you're interested! 🕺

🦀 Rust Aarhus and Alexandra Instituttet invite you to this free meetup for all interested in the programming language Rust 🦀 We have two talks, free food, and the opportunity to meet other Rust developers. 🦀 SecGPT: using LLMs for secure Rust code 🦀 By Benjamin Salling Hvass, Mikkel Wienberg Madsen, Gert Læssøe Mikkelsen, Bas Spitters. In the last couple of years, LLM based tools, like GitHub Copilot, have become a popular aide in software development. They have been used for autocompletion, for translations and in reasoning. However, they have a tendency to hallucinate and to produce insecure code. How well do they fare on rust, and can we use them to help us write safer and less vulnerable code? Rust is a new and somewhat smaller language, which is less represented in the training data. So, one can expect some challenges. At the same time, one can hope that rust's type checker and borrow checker can help to catch LLMs hallucinations. In this talk we will go over several ways we have tried to use LLMs in a more automated approach, from translation of other languages into rust, to fixing compiler errors and reasoning about software vulnerabilities. The talk is also an invitation to collect feedback and experiences in the use of LLMs from the Rust Aarhus community. [ The talk presents some of the outcomes of an explorative project supported by the CenSec cluster. ] 🦀 Hax - Rust for high-assurance cryptography 🦀 By Bas Spitters Bas will present the Hax toolchain for high-assurance cryptography in Rust. Hax uses Rust as a specification language for cryptographic primitives and protocols, together with formal methods tools to link those specifications to highly optimized implementations. Hax is being used in projects together with Microsoft research, Google, the Signal Foundation, ... There is also interest from the IETF, which standardizes internet protocols. Bas Spitters is associate professor CS, Aarhus University. When: 2024-09-26 18:00 - 21:00 Where: Aarhus Denmark Signup: https://lnkd.in/dyWNCYmA #rustaarhus #rust #rustlang #meetup #programming #computerscience #aarhus #denmark

Fantastic lessons learned through experience for Patrick Debois !! A sexy cool mix of all aspects: people, process, tech, psychology, economics! While I’m echoing, his lessons learned, the broader story in its context matter! Please read his post to really hear the evolution of a leader. - Assigning clear ownership of all things engineering - Introducing a buffer/fixed capacity for engineering work and running healthy - Levelling up engineering leaders beyond the scrum delivery - Making tech debt visible and automating the nagging ;) - Introducing a culture of engineering documentation and decision process using ADRs - Building cross functional “tables” combining analytics, marketing, product, engineering and design - Help drive ai innovation in the company both for engineering and product - Bootstrapping the internal developer productivity team and landing the data and ai platform as part of the “platform” team #HumansFirst #Leadership

Yesterday at Nordbygg, I had the honor of joining Anders Björling, Joakim Eriksson, Jonas Anund Vogel and Installatörsföretagen on stage for an engaging discussion about the crucial role of collaboration among all stakeholders in our ecosystem. Our focus was on unleashing the potential of structured building data to tackle environmental challenges, enhance energy efficiency, boost net operating income, and elevate property values. Our dialogue delved into the challenges and opportunities inherent in building data, spanning from data consolidation and data sharing to knowledge dissemination. We explored technical solutions, AI opportunities, security concerns, as well as financial and political incentives. I offered my insights on the obstacles we must overcome and emphasized how delivering #Open, #Flexible and #Independent solutions can address one of the industry's most pressing issues. This approach, I believe, is key to unlocking new opportunities for innovative solutions that benefit everyone involved. In consensus, we recognized structured, consolidated building data as a key for progress in our industry.

There is this joke in software development: the first 90% of the work takes 90% of the time, and the last 10% takes another 90%. We humans tend to think linearly about processes (just look at how we assume tech trends will just keep on going), but the joke does reveal a basic truth about complex systems. Sweden's police force, despite doubling its budget and staff, finds itself paralysed by an increasing number of internal controls. The Swedish police now have at least 589 separate regulatory documents, many contradicting each other. As one officer describes it, the force has become "an elephant that only eats Excel sheets." I see this transformation of sensible oversight into bureaucratic quicksand everywhere, and it is not surprising that The Swedish Work Environment Authority has recently started to look into digital work environment and found it severely lacking. Getting from 90% to 100% compliance costs more than getting from zero to 90%. Administrators and policymakers, perhaps dazzled by visions of perfect control and often with a lack of understanding of how the work is actually done, keep building centralised systems that ignore this basic fact. The Police chief's admission that she doesn't even know the number of her own regulatory documents is a pretty good implication of how deep the dysfunction is — a system so complex it defies its own accounting.. In accordance with Lessig's rule "Code is Law", digitalised documents usually demand perfection, leaving individuals to translate a messy reality to perfect checkboxes that have been designed by someone who does not pay the cost of filling them in. Furthermore, when you demand that users fill in a form that where many cannot adequately describe the reality they see, or where the question is uncertain, you will also fail to get working decision support - you don't need a lot of bad data to contaminate the entire data set. Humans can ask questions and handle complex answers, forms usually can not. Modern bureaucracies, quite intoxicated by dreams of perfect oversight, have engineered their own paralysis. Their digital systems demand perfect data where human judgement was once enough (a parallel here is how we no longer trust experts) Smart governance means knowing when good enough is, well, good enough. The emergency measures now allowing Swedish police chiefs to ignore governance documents highlight the absurdity of all of this. In an age of constrained resources, we can no longer afford to let perfect be the enemy of good, especially if we want to meet recent challenges and disruptions. The alternative is clear: doubled resources yielding diminished results, as public servants drown in paperwork instead of serving the public. The Police force may be the ones called out, but really, this is everywhere.

Both Ilya Sutskever and Jan Leike left OpenAI yesterday, with Ilya announcing that he will soon be revealing a new project. OpenAI estimated that Superalignment will be solved within four years. This means either they have successfully solved it, or else have realised that they are on the wrong path, and OpenAI won't be able to solve since focus has now shifted towards product and distribution. As for what superalignment or alignment means in general? In layman terms, whenever you enter some prompt in ChatGPT, you expect a particular answer in return. But often ChatGPT misunderstands and gives you the wrong answer. In some cases it might give you an approach that you didn't ask or is different from what you expected. Ex: Asking ChatGPT to calculate the area of a triangle from the given dimensions using Heron's formula. ChatGPT finds that the triangle is equilateral, and instead uses √3/4*a². Therefore the goal of superalignment is to ensure that Artificial Intelligence models stay within the bounds of human value, and their goal aligns with that of the requirements of a human, thus avoiding any unnecessary harm. Basically risk mitigation.

Next week (Thursday 26/9) I'll once again be haunting the Göteborg React Meetup with silly ideas and dark thoughts—more specifically, I'll be there presenting "Entropy, Rot, and Decay in IT and Software". You'll learn how entropy is a quite tangible, handy concept to help understand why organizations deteriorate and why technology orgs specifically rot, and eventually, decay into obsolescence. Like in the "whisper game", meaning breaks down when there are too many connections—big organizations struggle to be relevant, fast, and innovative: But they could be! If you ever thought the universe is against you, I will explain that "yes, it is". But that's OK, as you will also learn.

What’s the first step you should make before moving to cloud? Ask yourself WHY? ☁️ 💬 That’s typically what we ask our clients. Why do you want to move your application to cloud? What is your motivation? What are the pain points you’re currently dealing with? Moving to cloud just for the sake of moving to cloud isn’t enough. If you don't adapt to the cloud environment, you miss out on opportunities for increased efficiency and optimization within the cloud. Martin Hauskrecht talked about this and more with Oliver Kriska & Daniel Harcek in the 0101 Podcast, thanks for having us! Check it out 🎧 #podcast #lablabs #cloudnative #devops
