Free Software and Hardware

Software engineering is changing. Dramatically. Writing code today isn't what it used to be ... a mere few weeks ago. As AI coding agents start gaining more widespread adoption, "best practices" are still unclear. Nobody can still say for sure what should go in AGENTS.md, what the secret sauce for a good skill is. In this hands-on, [mob programming](https://www.baeldung.com/cs/mob-programming) session, we'll practice using some agents together, **learning from each other** as we go along: * how do we best prompt the agents to build a feature? * how can agents help with code review ? (we'll try out Mozilla's [star-chamber](https://blog.mozilla.ai/the-star-chamber-multi-llm-consensus-for-code-quality/) that gets multiple LLMs to review our code - and to discuss with each other before telling us the output) * spend the time in between discussing skills, subagents, hooks, and whatever else is new by then. Note: this is not *intended* to be claude code - focused, but it might turn out to be. If you have another favourite agent, please come along and show us how to use that instead! ;) **Sponsors** Our sponsors for this meetup are [Yodeck](https://www.yodeck.com/) \- who are not only kindly providing the venue\, free of charge\, but who will also treat us to some snacks / drinks for the networking session after the meetup\! Do stick around and say hi!

Hello DDDers, Just before the easter break, it's time to practice our data engineering chops! Let's welcome [Theodore Pantazopoulos](https://www.linkedin.com/in/teopant/) on stage, where he shall present his work on avoiding infrastructure traps and finding better ways to think about data and building leaner systems that scale. Stick around after the talk - not just for pizza, beers, and networking, but also because two lucky participants will win tickets for the upcoming [Devoxx](https://devoxx.gr/) conference, that takes place at the end of April, and features a stellar speaker lineup. We also have some announcements for the next meetup, where we will celebrate the 10th anniversary of this community! **Talk: Beyond the Pipeline: A Smarter Paradigm for Data Engineering** For decades, the default response to every data challenge was the same: add more infrastructure. More servers, more pipelines, more complexity. This talk challenges that assumption. We'll explore how a fundamental shift in thinking, treating data producers as partners in a contract rather than passive sources to be queried, can eliminate entire layers of engineering overhead, reduce costs, and simplify architectures that have grown unnecessarily complex. This paradigm proves especially powerful in constrained resource environments, whether that means teams and organizations that cannot afford over-engineered pipelines or expensive clusters, or architectures that are constrained by design, such as microcontrollers, embedded systems, and edge devices where compute and memory are fundamentally limited. **Speaker bio** Theodore has been shipping data infrastructure that actually scales. As a Principal Engineer, creator of the open-source streaming-sql-engine, and contributor to numerous open-source projects, he's built large-scale data processing systems that power core products and drive business decisions. With experience across global corporations, high-growth startups, and industry leaders such as Citrix, Delivery Hero, and shopflix, and deep expertise in Go, Python, and data engineering, he specializes in turning complex data challenges into reliable, high-impact solutions. **Meetup Outline** 18:30 - 18:45 Warm welcome 18:45 - 19:45 Talk by Theodore 19:45 - 20:00 Devoxx ticket giveaway 20:00+ Networking & Discussions **Sponsors** XM is kindly hosting the event on their premises, which are located only 5' on foot from Megaron Athens. XM ([https://www.xm.com/](https://www.xm.com/)) is an award winning online trading broker firm that serves clients from over 190 countries on 5 continents. It is now an established fintech organisation with core capability of software, platforms and product development. All the best, [DDDGreece meetup team](https://twitter.com/dddgreece).

📅Την Κυριακή 5 Απριλίου, ώρα 15:00 και σχεδόν στην καρδιά της Άνοιξης, ξεκινάμε από την μονή Αγίου Ιωάννη Κυνηγού στην Αγία Παρασκευή για να πιάσουμε μία από τις κορυφές του Υμηττού. Την κορυφή Κορακοβούνι! 🎋 Πρόκειται για μία όμορφη ημικυκλική διαδρομή 8,5 χιλιομέτρων στον Βόρειο Υμηττό, με αρκετές εναλλαγές τοπίων αλλά και γεμάτη με εντυπωσιακά σημεία θέας προς το λεκανοπέδιο! (Δείτε τις φώτο πιο κάτω) Στη πορεία μας θα συναντήσουμε και το περιβόητο σπήλαιο λιονταριού! Το όνομα του σπηλαίου δεν είναι τυχαίο. Περισσότερες λεπτομέρειες στο σημείο. ⚠️ ΠΡΟΣΟΧΗ: Η διαδρομή αν και σχετικά μικρής απόστασης ΔΕΝ λογίζεται ως εύκολη ή κατάλληλη για αρχάριους. Το πρώτο μισό της διαδρομής έχει ανοδική κλίση, ή όποια σε διάφορα σημεία αυξομειώνεται. Το δεύτερο μισό έχει και κάποια σημεία με έντονη καθοδική κλίση. Επίσης το 80% της διαδρομής είναι μέσα από μονοπάτια. ⌛ Η διάρκεια της μετρήθηκε επί τόπου με scouting στις 3 ώρες, ωστόσο για όσους επιχειρήσουν να το τολμήσουν, ας γνωρίζουν ότι ο ρυθμός θα είναι απόλυτα χαλαρός, με μπόλικα διαλείμματα και χωρίς πίεση χρόνου. Γι αυτό επιβάλεται να πάρετε μαζί σας και φακό. Διότι δεν ξέρουμε αν οι 3 ώρες γίνουν 5 στο τέλος λόγω μείωσης του ρυθμού βάδισης ή της αύξησης αριθμού στάσεων! 🤷🏻‍♂️ Εκτός από φακό, μαζί σας πρέπει να έχετε και: 💧 ΤΟΥΛΑΧΙΣΤΟΝ 1 λίτρο νερό. Ιδανικά 1,5. 👟Αντιολισθητικά υποδήματα 🧢 Καπέλο (προαιρετικά) 🦯 Όσοι έχουν μπατόν ας τα φέρουν θα φανούν χρήσιμα. Και όσοι δεν έχουν, αν σκέφτονται να αγοράσουν, μάλλον τώρα είναι η κατάλληλη ώρα. Δεν θα το μετανιώσουν. Ειδικά όσοι δεν έχουν πολύ καλή φυσική κατάσταση. 😎 Επίσης απαραίτητο κρίνεται: 😋Την προηγούμενη μέρα να έχετε φάει καλά. 🍌🥜 Την ημέρα της δραστηριότητας να έχετε κομμένα νύχια ποδιών (ναι!) και μαζί σας ενεργειακά σνακ όπως, μπανάνες, σταφίδες, ξηρούς καρπούς ή έστω ενεργειακές μπάρες. 🗺️ Εδώ είναι το ακριβές [στίγμα συνάντησης](https://maps.app.goo.gl/68xZp6Y8rpc56eJg9) 👈🏻 ✍🏻 Συμμετοχή μπορείτε να δηλώσετε μόνο μέσα από αυτή [την φόρμα ](https://luma.com/6rnovtzz)👈🏻

The inner circle consists of a small number of participants who actively discuss a topic, while those in the outer circle listen and observe. This format encourages participation from all members, as individuals from the outer circle can join the inner circle by taking an empty seat when they wish to contribute.](https://www.bing.com/ck/a?!&&p=00b4b265baa395dc4ad7b262d4d6e3b7b7c31b2195941076e51d2eca252c2d02JmltdHM9MTc2MjgxOTIwMA&ptn=3&ver=2&hsh=4&fclid=0e60c23d-2dbf-642d-0fd7-d4512c2b6597&psq=fishbowl+discussion&u=a1aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvRmlzaGJvd2xfKGNvbnZlcnNhdGlvbik&ntb=1)

Central Ohio Radio Enthusiasts—CORE—is an informal community for anyone enthusiastic or curious about radio—whether you're new to radio and want to learn or you've been tinkering for years and want to share. Ham radio operators, GMRS users, Meshtastic fans, software-defined radio nerds, makers, and technical and non-technical folks are all welcome. No experience required or expected. This month we have **WiFi HaLow: Introduction and Practical Use** with **Alex Barbur**. Details are are [core.radio](https://core.radio).

The emotional pain from past bad experiences easily lingers in the present, making it hard to enjoy life and create your future. Even when you think you've moved on, the negative emotions can be triggered, sending you back into the pain of that experience. And we are talking about pain; emotions such as grief, depression, anxiety, fear (or terror), boiling anger, simmering resentment, feelings of shame, blaming and regret can leave you incapacitated to a greater or lesser degree. In this local event we will be discussing the reasons why these past bad experiences have the power to affect you long after they occurred. We'll go over why the emotional pain can be so strong. We'll also discuss some simple solutions to overcome your emotional pain and be free to fully enjoy your life again. Examples of painful experiences include: * A broken relationship or divorce. * Death or loss of a loved one. * Death of a pet. * A sudden shock or bad news. * A betrayal. * Being part of an abusive relationship. * A bad injustice. * Loss of a job, position or business. * A grave illness or injury. The negative emotions from these experiences don't just go away on their own. But the good news is there is a way to clear them out of your way. Be sure to click on the red "Attend" button below to come to this local event. We look forward to seeing you there. This group is sponsored the Dianetics & Scientology Self-Improvement Center.
