🦀 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.

Lots og people are making predictions, and we usually remember the ones that turned out to be right. It’s a bias. That’s why I rarely try and make predictions. Except today. I think the next big thing will be that idp (internal developer portals) will become a control plane. Take backstage. At best it’s a templating engine and plugin enabled platform. But connect it to a queue (eg Kafka), let it react to events and do things will turn it into a full fledged control plane. Something happens in ci, backstage reacts. Something happens on a developer laptop (eg release a service) backstage does it. Kubernetes events could trigger backstage to start an on-call. So many possibilities. That’s my prediction.

When we first built Forsler.com (Skovkortet.dk at that time), we didn’t adopt an API-first approach. Skovkortet.dk was an “isolated” platform, designed to work well on its own but not integrate easily with other systems. While it functioned as intended, we quickly realized the limitations of this approach. Without an API-first design, we faced several challenges: - Our platform couldn’t easily communicate with external tools. - Each new integration was a heavy lift, requiring custom development for every partner. - We essentially built a walled garden, limiting collaboration and flexibility for our users. This experience taught us a valuable lesson: platforms that don’t prioritize integration risk becoming outdated and siloed. At that time, we were only operating in Denmark under Skovkortet.dk. But as part of our vision for Forsler.com, we realized that without an API-first approach, we would never be able to scale effectively or expand into other countries. We knew that if we wanted to grow, API-first had to be at the core of our strategy. Have anyone else tried to transition a platform to an API-first principle? P.S. i just love these AI generated images 🤣

The intersection between speedcubers and neovim users is probably not that high, but there is atleast one in existance (yours truely), so here we are. I felt the pull of the lua language yet again and decided to create a small plugin for neovim. The usual problem of "what should the plugin do?" arose but I quickly fell upon something that I always have on my desk when I work: my cube. Everyone has seen one, but not a whole lot of people can solve them. To solve them you need to scramble them. This seems like a strange issue but when you solve the cube in less than 30 seconds you might need to scramble the cube quite a few times in each session. Hence this plugin, now I can get a scramble whenever I want by just pressing the appropriate key mapping in neovim. My personal best on the cube is 19.60 seconds. My best average of 5 (do 5 consecutive solves, remove the slowest and the fastest and average the rest) is 27.46 seconds. By no means great but decent for a hobbyist. As a reference the world record is 3.13s single solve and 4.48s average of 5. Here is the plugin. https://lnkd.in/dqyHNmz6 A small note about the name of the plugin: When I got the idea I was listening to the song Den Svarta Fanan and decided that I wanted to honor Miesko Talarczyk (RIP) by naming the plugin after a song that he created.

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.

In my years as a software engineer, I’ve been part of projects that remind me a bit of Frankenstein’s monster. 🧟‍♂️ You start with an idea that sounds a little crazy. People give you strange looks, but you gather the parts you need, or sometimes dig 𝚜̶𝚘̶𝚖̶𝚎̶ ̶𝚐̶𝚛̶𝚊̶𝚟̶𝚎̶𝚜̶ deep into forgotten places, and after some serious effort, you bring it to life. You can scream “It’s alive, alive!!”, and it works! It’s functional, you’re proud of it, and it’s actually useful. You’re no longer the "mad scientist." 🧑‍🔬 But fast forward a few years… The stitches holding everything together start to strain, things creak under the surface, and suddenly, people are showing up at your door with torches and pitchforks! 🔥 There is some hidden teaching in this about Software Maintenance, Technical Debt, and Day 2 Operations .... but it seems the front door is about to break down from the crowd and those pitchforks look very sharp! 👨‍🌾 On a serious note, the first lines of the preface in the Google SRE Book say it best: "Software engineering has this in common with having children: the labor before the birth is painful and difficult, but the labor after the birth is where you actually spend most of your effort. Yet software engineering as a discipline spends much more time talking about the first period as opposed to the second, despite estimates that 40–90% of the total costs of a system are incurred after birth." #SoftwareEngineering #TechLife #Coding #TechLeadership #SoftwareDevelopment #ProgrammingHumor

I love Backstage from Spotify But I feel that people are given a fantastic tool, but not guidance on how to use it. We’ve had platform engineering for a couple of years now, and now the new hype is Developer Experience. This is where Backstage is the go-to platform. But, we keep on making the same mistakes again and again in our industry. Do you have a strategy for your backstage offering ? Who is your target audience? What do they NEED ? Do they need a Flux plugin ? Do they need a Kubernetes plugin ? NO. They need to create products, ensure they are ok and release new features. It needs to be developer centric. You need to understand their domain, needs, problems and concerns and then think about how you can ease or provide help with Backstage. Make the responsibility clear on both the developer and platform side. Who is responsible for what ? What signals do they need to react to the things they are responsible for ? Anything more then that is noise. Confusion. Build a Backstage platform your developers need, not the one you need.

☕️ Knowledge & Coffee #2 ☕️ Next up - Elias Henriksson. Elias has worked at Elastic Move for five years now and he keeps impressing us with his knowledge. Except for being a great cloud architect he’s also known for making the most magical sourdough bread! 🍞 During his session, Elias taught us more about a solution he made for one of our clients using AWS EventBridge. The challenge he faced was that our client needed a solution to transfer files from S3 to an EC2 instance automatically.  By leveraging S3 Events to trigger actions whenever new files were uploaded, this way, the recipient was automatically notified when a new file was ready to be retrieved. The result was an Event-Driven Architecture (EDA) that solved the problem efficiently and seamlessly without manual intervention. With his innovative use of AWS EventBridge, Elias not only met the client's needs but showcased the power of Event-Driven architecture in creating automated, scalable solutions. Thanks for sharing your knowledge, Elias! ☁️ #ElasticMove #HomeOfCloudSpecialists #AWS

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

- It is a moon landing for us. Night and day, Magne Eriksen, Technical Director at Scala Eiendom says 🚀 Now all types of documents are automatically sorted and categorized by Findable. For Magne it’s a small revolution. – Manually categorizing, maintaining, and operating a document archive is incredibly demanding. Historically speaking, I would say that it was often not achievable at all, he says. Findable is now rolled out across all of Scala’s shopping centers.

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 ?
