**Frontend developers in 2026 are spoiled for choice. New frameworks promising freedom, AI assistants promising to handle the boring parts. But between the framework debates and the quiet burnout, what actually delivers in day-to-day work?** Join us on **Tuesday, May 26**, for an evening focused on the honest reality of frontend development in 2026. Four engineers from Applifting and Mews will share what's actually working—and what isn't—in framework decisions, AI workflows, and the human side of keeping up with constant change. Let's meet in the **Applifting meetup space**, both in person and online. **We’ll start at 18:00.** 👉[ Register here](https://applifting.io/events/frontend-crew-talk-when-tools-move-faster-than-us) 👈 **if you want to attend in person. Spaces are limited and our event planner Anetka would be sad if we had to turn you away at the door!** **Who’s speaking?** **[Michal Čížek](https://www.linkedin.com/in/michal-%C4%8D%C3%AD%C5%BEek/)**, senior frontend developer at Applifting, will open with a side-by-side comparison of Next.js and TanStack Start—two frameworks with fundamentally different philosophies—to help you pick for your next project. **[Jan Marek](https://www.linkedin.com/in/j4n-marek/)**, senior software engineer at Mews, will follow with how frustration and laziness can guide useful AI workflows, automating each “I don't want to do this manually” from Slack thread to announcement. **[Tereza Šimková](https://www.linkedin.com/in/simkovat/)**, also a senior frontend developer at Applifting, will offer an honest, non-technical look at the hidden psychological toll of working with AI coding assistants. Then, they will be joined for the panel discussion by **[Matyas Mihálka](https://www.linkedin.com/in/matyasmih%C3%A1lka/)**, frontend tech lead at Applifting, bringing a grounded take on what AI coding tools actually deliver day-to-day and how to adopt them without burning out. **We look forward to meeting you!** **Schedule:** **17:30 – Doors open** * Get your ticket ready, say hello to others, and have a drink with us. 🥂 **18:00 – Introduction by Filip Kirschner** * Our co-founder Filip will give you a short welcome and introduce our speakers. **18:15 – Two philosophies, one decision: Next.js vs TanStack Start in 2026 with Michal Čížek** * *Next.js has shaped React for years.

Hello Python extractors and vulnerable agents, The 35th PyData meetup will take place at **Aisle offices** (Palác Zlatý kříž, 2nd floor). As usual, the talks will start at 18:30 but we encourage you to come as soon as **18:00** to enjoy the opportunity to socialize and refresh yourselves (which you can continue doing during the break and after the talks). Our main goal is to build the community around Python and data and make it welcoming to people of various skills and experience levels. ⚡ If you are interested in giving a lightning talk (up to 5 minutes to present an idea, tool or results related at least to some degree to Python and/or data), please contact us before the event or at its beginning. **What a Single-File LLM Security Analyzer Taught Us?** **([Stanislav Fort](https://www.linkedin.com/in/stanislav-fort/), Aisle)** High-quality AI security research can uncover real vulnerabilities in critical infrastructure. AISLE is one example of this higher-signal approach, with validated findings in projects like OpenSSL and curl. At the same time, low-quality AI-generated reports are flooding open-source maintainers with false positives. How hard is it to find a security bug? We will explore that question through nano-analyzer, a deliberately simple open-source security scanner. For many vulnerability classes, the surprising core is not a complex platform, but a well-aimed LLM call wrapped in the right workflow. This simplicity has limits. The approach may miss obvious issues, hallucinate risky findings, or produce inconsistent results across runs. That is why validation, triage, benchmarking, and human judgment matter, and why the real challenge is building reliable processes around unreliable primitives. **Getting reliable text when PDFs lie and OCR fails** **([Marcela Brichtová Piptová](https://www.linkedin.com/in/marcela-brichtov%C3%A1-piptov%C3%A1-b950ba184/), Rossum)** LLMs need text as an input. So before a model can reason about a document, we have to read the text, a step often treated as the "easy part" or a solved problem. But is it? In this talk, we will explore the hidden complexities of text extraction. This is especially critical for models like Rossum's T-LLM, an encoder-only architecture which heavily relies on high-quality input. You will learn why transactional documents are sometimes surprisingly hard for OCR, why you can't always just copy-paste text from a PDF, and why text extraction is still a topic for Rossum researchers (and our customer support team).

## 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.

Instruction level parallelism by [Ivica Bogosavljević](https://johnnysswlab.com/author/ibogi/) Instruction Level Parallelism (ILP) is the magic ingredient of a modern CPU that makes it run fast. But not all programs are equal, some have more ILP, others have less. In this talk we are going to investigate our codes from the viewpoint of ILP: which code has more ILP, which has less ILP, how does ILP affect software performance and what techniques we can use to speed up our software.

PangeAI is building agent-driven geospatial intelligence for anyone, turning natural language queries into instant spatial analysis and decisions, with no GIS knowledge required. Backed by autonomous agents we're focused on use cases geospatial context drive real decisions. We're headquartered in the Bay Area with our European HQ right next door in Prague. Maps encode rich spatial context that today's AI agents largely fail to interpret. In this talk, I'll share how we're teaching agents to "read" maps in production at PangeAI starting with geospatial embeddings as a practical foundation for geo-similarity detection, then layering multi-agentic orchestration on top to generate strategic geospatial insights at scale. Along the way, I'll walk through the tooling and frameworks we've built to make all of this tractable for engineers, with real-world examples and open questions at the intersection of geospatial data and agentic AI.

At the group's first meetup, we will informally discuss whether self-improvement has an end or is a never-ending process. To inspire the discussion, I selected two short blog posts with opposing perspectives. The [first post](https://markmanson.net/self-improvement#:~:text=There%27s%20a%20paradox%20with,the%20need%20to%20improve%20yourself.) is by Mark Manson, the author of *The Subtle Art of Not Giving a F#ck*. He argues that: “*There’s a paradox with self-improvement (...): the ultimate goal of all self-improvement is to reach the point where you no longer feel the need to improve yourself (…). The whole goal of improving your productivity is to reach the point where you never have to think about how to be more productive. The whole point of pursuing happiness is to reach the point where one no longer has to think about being happy. (…)* *The only way to truly achieve one’s potential, to become fully fulfilled, or to become “self-actualized” (…), is to, at some point, stop trying to be all of those things.”* The [second post](https://maartenvandoorn.medium.com/self-improvement-doesnt-have-an-end-it-is-the-end-6bbb3247ff6f) is by Maarten van Doorn, who wrote it as a reply to Mark Manson’s post. Van Doorn argues that self-improvement doesn’t have an end because it is an end in itself: *“‘The paradox of self-improvement’, as Mark calls it, is not that self-improvement, despite appearances, has as its ultimate goal something that’s ‘in your head’. No, the true paradox of self-improvement is that it’s perhaps the only kind of improvement that is not done for the sake of whatever it is being improved, but for its own sake.* *Self-improvement has intrinsic value and, in contrast to productivity, becoming better and exercising skills are essential components of what makes life worth living (…)* *Personal growth shouldn’t be thought of as a band-aid to fix something. That’s not what it’s for. What it’s for, is to prevent you from settling for eternal boredom — and your life from going by unnoticed*.” What do you think? **Reading the posts beforehand is optional** — Just in case you want to read them, here are the links: * ‘[What is self-improvement’ by Mark Manson](https://markmanson.net/self-improvement#:~:text=There%27s%20a%20paradox%20with,the%20need%20to%20improve%20yourself.). * ‘[Self-improvement doesn’t have an end, it is the end’ by Maarten van Doorn](https://maartenvandoorn.medium.com/self-improvement-doesnt-have-an-end-it-is-the-end-6bbb3247ff6f) We will also have time to talk about ourselves and brainstorm ideas for next meetups. See you soon. Ángel

Most people use AI like a search box: they type one sentence, hope for the best, and get frustrated when the answer is generic, wrong, or useless. But getting better results from tools like ChatGPT, Claude, Gemini, and other AI systems is not about memorizing magic prompts. It is about learning how to give the AI better context. In this beginner-friendly session, we’ll break down how to make AI dramatically more useful by improving the way you communicate with it. You’ll learn how to give clearer instructions, provide examples, set constraints, ask for better output formats, and use follow-up questions to turn a mediocre answer into a genuinely useful one. We’ll cover practical techniques you can use immediately for work, learning, writing, coding, planning, research, and everyday problem solving. We’ll also touch on why these same ideas show up in more advanced AI systems, including RAG, agents, evaluations, and AI workflows. No technical background required. Bring your curiosity, your questions, and maybe one real task you wish AI was better at helping you with. **What you’ll learn:** * Why “better prompting” is really about better context * How to structure requests so AI gives more useful answers * How to use examples, constraints, and output formats * How to iterate when the first answer is not good enough * How these skills connect to more advanced AI workflows This meetup is for anyone who wants to move beyond basic ChatGPT usage and start getting more practical value out of AI. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8.

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!
