## Learn Go and NixOS deployments with large language models Hello, 世界! When used sensibly, language models can be tutors, too. For meetup #60 on Tuesday [May 26, 2026 19:00 CET](https://www.meetup.com/leipzig-golang/events/312537727) we are really happy to have [Maxime](https://www.linkedin.com/in/plumps/) dive into Nix/NixOS with the help of language models. Nix is a functional package manager and its immutable traits enable robust, reproducable deployments of Go (and other) projects. The high level goals of Nix/NixOS are similar to other immutable Linux distributions, like [Silverblue](https://fedoraproject.org/silverblue/) or [Bazzite](https://bazzite.gg/). Becoming familiar with the Nix configuration language can be a challenge, but one that a well instructed tutor may help with. > Artificial intelligence techniques are increasingly used in education to enable personalized learning and intelligent tutoring [LLM Agents for Education: Advances and Applications](https://aclanthology.org/anthology-files/anthology-files/pdf/findings/2025.findings-emnlp.743.pdf) (11/2025) Why reproducible and immutable deployments play a role? [Justin Garrison](https://justingarrison.com/blog/state-of-immutable-linux/) says: > It’s 2026, if you’re not using something immutable (or at least reproducable) you’re doing more maintenance work than you should.

Combinatorial optimization problems arise across logistics, scheduling, and engineering, and C++ remains a language of choice when performance matters. This lecture takes a practical look at solving such problems in C++, using the Electric Vehicle Routing Problem as a running example. We begin with an exact solver, formulating the problem as a mixed-integer program and trying to solve it through GLPK's C API directly from C++. Exact methods, however, quickly hit their limits on real-world instances. The second half of the talk turns to metaheuristics: how they are designed, why C++ is particularly well suited for implementing them, and what design choices matter most in practice. We'll walk through a concrete implementation, touching on data structures for fast neighborhood evaluation, generic algorithm design with templates, and the performance considerations that separate a prototype from a production-ready solver. The goal is not to advocate for one approach over another, but to show how C++ supports the full spectrum of optimization techniques. # About Speaker Luka Matijević is a researcher at the Mathematical Institute of the Serbian Academy of Sciences and Arts, whose work bridges academic research and freelance engineering. He's drawn to identifying the right algorithm for a given problem — and to the kind of careful optimization captured by one of his favourite Futurama lines: *"When you do things right, people won't be sure you've done anything at all."* ## 📅 Event Details | | | | --- | --- | | 👤 **Speaker** | **[Luka Matijević](https://www.linkedin.com/in/luka-matijevic/)** | | 🕕 **Date & Time** | **27th of May (Wednesday), 6 pm** | | 📍 **Location** | **Beograđanka, Vidikovac, 22nd floor** | | 🏢 **Address** | **Masarikova 5** | | 💻 **Online** | **[C++ Serbia YouTube](https://www.youtube.com/@cppserbia)** | See you!

This is a free, in person meeting. Burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse. Whether in love or personal ties, with friends or at work, our life really IS affected by the quality of our relationships. Good ones can promote pleasure and survival while less optimum ones can lead to annoyance, anger, self-doubt, stress, or even affect our health and ability to survive well. Whether you are suffering from a divorce, or a painful break-up, don’t know who to trust (or who to CHOOSE) as a partner, friend, boss or employee - the anxiety of relationship troubles can really make a mess of things. Maybe you’ve suffered a betrayal, or are dealing with hostility or criticalness or invalidation. Dwindling relationships can involve destructive behavior, where we hurt those we love, or start succumbing to self-destructive thoughts, attitudes or behaviors that spiral out of control and affect much more than our immediate relationship. Past losses in love or life can affect how we act or react to new people and situations and hold us back from even starting to create new, possibly great relationships! How can one get back onto a saner course of action? Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life: human relationships! Break free from self imposed limitations Here we will discuss: • How to “erase” the trauma of past hurts and betrayals so that one isn’t always repeating past mistakes. • Why and how do the negative emotions of others affect you? • Why is my partner withdrawing and what can I do about it? • Why do we sometimes feel compelled to hurt the ones we love? • Fights & arguments - what's really behind them? • What underlies “corrosive criticism” or the need to invalidate self or others? • How one can stably change one’s outlook on life so they can affect positive change? • Where do compulsive destructive behaviors come from and what can be done about them? • How to form closer bonds & keep growing the relationships with the people you care about? • How to enhance one’s own ability to survive and create positive healthy relationships whether in love, family & friendships or in work, business or one’s career? Relationships can be hard and life itself IS challenging. Why not arm yourself with the knowledge and breakthroughs that have been made about the mind, mental reactions & interpersonal relationships, so that one has better awareness and control over themselves and life in general. Learn where painful experiences are “stored” and how they can unknowingly affect us. You will also find out how one can “erase” those past painful experiences so that one is free to move forward without being tripped up by the past. Learn too, about what can lead some people to become “toxic” personalities and how to identify those traits in others so you won’t be tripped up trusting the wrong person. Our free Meet-ups occur in a safe environment where one can learn, without fear of judgment or criticism, and without the recommendation of harmful mental techniques or therapies, just how YOU can get yourself onto a happier & more successful path: in love & in life. We look forward to having you join us! This class is sponsored by the Dianetics & Scientology Life Improvement Center of Central Ohio.

This is an in-person meeting. Did you know that unwanted emotions like loneliness, sadness, hopelessness, anger, fear, anxiety, or feelings of irritation don’t just fall on you for no reason. They are not random occurrences that simply happen to people's minds. They are definitely not chemical imbalance in your brain due to some nebulous chemical reactions by chance. Your negative emotions are the symptoms of the painful experiences that you have which are not healed, and which are still affecting you. The effects of these painful experiences are exacerbated by the pressures or difficulties of the other problems in your life. For instance, let's say you are already carrying a huge load on your back, then you cannot take on much more, but, let's say something else happens to you, such as the difficulties from the Pandemic, then the resultant combined weight on you can take you over the edge, kind of like the straw that break the camel's back. When this happens, people's attention usually goes to the straw that was added, but actually the majority of the weight had come from the huge load that were already there, holding a person down and causing a person issues. So how do you remove the huge load that was already there? How do you lighten them up? Is it possible to get rid of them? That is what this meeting will be all about. Come to our Meetup, where we can introduce you to some of the knowledge, tools and techniques of the breakthroughs in the field of the mind that we can apply to this ever important area of life.

Join us for this free, in person meeting on the subject of betrayals, losses and how to get over them so you can build lasting relationships. Do you want more motivation and confidence to build lasting relationships? Are you burdened by a stressful relationship? Unhealthy relationships can trigger feelings of anger, despair or self-doubt. They can create dwindling spirals of fights and seeking to make-up, or trying to “pin the blame” on someone or something. If you don’t find the RIGHT reasons, or select the correct sources of the problem, the problem can just get worse and worse.
