Coding with AI: the last 3 months - Matteo Vaccari
Per il mese di Marzo accogliamo nuovamente un ospite speciale, a un anno esatto dall'ultimo intervento fatto per noi. Esponente di spicco del movimento Agile ed XP in italia, membro storico del gruppo di *eXtreme Programming Milano* : **Matteo Vaccari**.
Portandoci *"Coding with AI: the last 3 month"* ci racconta le novità che ha esplorato e sperimentato negli ultimi mesi sul coding con l'AI.
\- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \-
**Abstract**
La programmazione assistita dall'IA si sta evolvendo rapidamente. Negli ultimi mesi sono emerse due tendenze: lo spec-driven development, ovvero la stesura di piani dettagliati prima della implementazione, e l'harness engineering, ovvero l'utilizzo di test, linter e controlli automatizzati per mantenere l'IA sulla strada giusta. Parlerò di questi trend e della nostra esperienza recente applicandoli a una codebase reale dove vogliamo (a) non scrivere mai codice a mano e (b) ottenere codice di alta qualità
**Bio**
Extreme programmer, Thoughtworker, trainer, coach and software developer. Deeply interested in what makes teams and companies successful beyond expectations! Any opinion expressed are my own.
\- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \- \-
**Dove ci troviamo?**
Anche questo mese siamo ospiti di [Thoughtworks Italia](https://www.thoughtworks.com/it-it/about-us/Chi-Siamo-Thoughtworks) nella sua sede milanese in Via Filippo Turati, 30:

Tech Startups in the Pub - Milan (6:30 PM CET)
🍻 **Join Us for Tech Startups in the Pub - Milan Edition!** 🍻
Hey there! 🌟
We'd love for you to join us for our next edition of *Tech Startups in the Pub,* this time in Milan, Italy!
The event is scheduled for **6:30 PM local Italian time**. The platform does not allow us to change the time zone, so we can only create events with the GMT time, thus you will see the invitation for 7:30 PM, but you definitely want to come earlier.
It's a relaxed evening at The O'Connell Irish Pub, and run by Volodymyr. We have been running for 3.5 years in London and we are excited to now run our monthly events in Milan as well, welcoming new folks to the community.
Whether you're a tech founder, an enthusiast, a budding entrepreneur, or simply curious about the tech scene, you'll fit right in. This isn't about panels or pitching, just good old-fashioned networking with like-minded people over a drink on a Thursday evening.
Important information about the location and time. **It is in the ZTL zone**, so please do not come by car. Please use public transport or walk.
**House Rules:**
* Find Volodymyr to introduce yourself so we can welcome you properly. The pub knows we are coming, so you should be able to find us easily.
* No hard selling or heavy pitching. This is a chill, friendly after-work get-together.
* Not drinking? No worries! You're more than welcome to come hang out and enjoy the conversation.
Mark your calendar and come down for some fun tech talk. See you there!

ROMA | RITIRO DI EVOLUZIONE INTERIORE
**Un Viaggio di 3 Notti verso la Presenza, la Chiarezza e la Connessione Interiore.**
Questo ritiro è un invito a rallentare, respirare e tornare a te stesso.
Svolto in un ambiente tranquillo immerso nella natura vicio a Roma, questo ritiro di evoluzione interiore di 3 notti offre uno spazio sicuro e accogliente per l’esplorazione interiore, l’integrazione emotiva e una riconnessione significativa.
È pensato per chi sente il bisogno di fermarsi, ascoltare dentro di sé e riallinearsi con ciò che conta davvero.
Il nostro lavoro si basa sul Metodo di EVOLUZIONE INTERIORE — un processo gentile ma profondo che combina consapevolezza emotiva, pratiche incarnate, auto-indagine, presenza relazionale e integrazione guidata.
Sono disponibili strumenti ancestrale opzionali, ma non sono mai al centro. Il cuore del ritiro è lo spazio che creiamo insieme, dove chiarezza e comprensione possono emergere in modo naturale.
Invece di cercare risposte all’esterno, questo ritiro ti accompagna a riconnetterti con la tua intelligenza interiore, permettendo che comprensione, liberazione e direzione nascano da dentro.
Questa esperienza è per chiunque si senta chiamato a uscire dal rumore della vita quotidiana e a immergersi in pochi giorni di semplicità, onestà e contatto autentico — con sé stesso, con gli altri e con la natura.
**La prenotazione include:**
• Alloggio e pensione completa, con opzione vegana o vegetariana.
• La partecipazione ai laboratori di approfondimento con i nostri facilitatori, che servono anche come preparazione prima della sessione notturna.
• Le integrazioni di gruppo del mattino per condividere l’esperienza o ampliare la comprensione di ciò che sta accadendo nel tuo processo.
• Una sessione con strumenti ancestrali ogni notte di ritiro (se vuoi farne più di una durante il giorno di ritiro, si considera come una sessione aggiuntiva) con l’accompagnamento della nostra equipe di facilitatori.
• Appoggio prima, durante e dopo il ritiro
• Sessione integrativa online post ritiro.

Road to HACK: Fine-Tune Your Own AI Model | Hands-On Workshop
Large language models are impressive out of the box — but they hallucinate, they're generic, and they need the cloud.
What if you could take a small open-source model and turn it into a domain expert that runs on your own hardware?
That's exactly what we're doing in this hands-on workshop.
**[Luca Massaron](https://www.linkedin.com/in/lmassaron/)** — data scientist, bestselling AI author, 3x Kaggle Grandmaster, and Google Developer Expert — will walk you through a complete fine-tuning pipeline from scratch: evaluate a base model, generate synthetic training data, fine-tune with QLoRA, and measure the improvement. All on consumer-grade hardware.
By the end of the session, you'll have a repeatable playbook for making small models punch way above their weight in any domain you care about.
**What you'll work through:**
Baseline evaluation of a pre-trained model → Synthetic dataset generation from real sources → Supervised fine-tuning with QLoRA (parameter-efficient, memory-friendly) → Post-training evaluation to measure the knowledge gain → **Bonus:** fine-tuning for classification tasks (sentiment analysis)
**What to bring:**
**Your laptop**. The workshop runs on Google Colab (free T4 GPU tier), so no fancy hardware required — just a browser and a Google account. If you have a machine with an NVIDIA GPU (16GB+ VRAM) or an Apple Silicon Mac (16GB+ unified memory), you can run everything locally too.
**This event is part of Road to HACK — the official warm-up series for [GDG AI HACK 2026](https://gdgaihack.com/).**
On May 8–10, 160 selected participants will compete in a 24-hour AI hackathon in Milan, with tracks spanning on-device AI, vision AI, and EdTech.
Fine-tuning is one of the most directly applicable skills you can bring to the hack.
Applications for GDG AI HACK 2026 are open **until April 17 →** [gdgaihack.com](https://gdgaihack.com/)
Venerdì al NOIR LISSONE

CityStore: l’ecosistema fisico e digitale che connette la tua città
Quante iniziative di digitalizzazione territoriale esauriscono la propria spinta propulsiva a pochi mesi dal lancio, riducendosi a piattaforme sottoutilizzate o distanti dalle reali necessità del tessuto economico?
Il limite risiede spesso nell’approccio: la tecnologia intesa come fine, anziché come infrastruttura abilitante.
**Lunedì 27 Aprile**, le istituzioni, le aziende e i professionisti del territorio saranno invitati a partecipare ad una serata di alta divulgazione. In questa occasione sarà possibile prendere parte ad un confronto strategico su come il digitale possa agire da collante per una rigenerazione urbana tangibile e sostenibile.
Durante la serata verranno approfondite le seguenti tematiche:
* **Bando di distretto**: un’occasione unica per poter investire nella propria città rilanciando l’economia locale.
* **Welfare di Prossimità**: la creazione di un ecosistema dove i benefit aziendali alimentano direttamente l’economia locale.
* **Cashback Territoriale**: modelli di circolarità economica per trattenere il valore all’interno del bacino cittadino.
* **Integrazione Phygital**: l’evoluzione del commercio tradizionale verso un’esperienza fluida che unisce prossimità fisica e servizi digitali.
Questa serata sarà l’occasione per analizzare come l’infrastruttura di CityStore, e in particolare il caso studio di SeregnoStore, possa offrire alle imprese e alle istituzioni locali, degli strumenti concreti per far rifiorire la propria città. City Store non è solo un software, ma un ecosistema fisico-digitale che permette di mettere in connessione tra loro cittadini, imprese, attività commerciali e istituzioni.
Ti invitiamo a prendere parte a questo dialogo per definire insieme la Seregno del futuro: una città interconnessa, dove tecnologia e comunità convergono in un unico progetto di sviluppo.
📅 **Quando?** Lunedì **27 Aprile** alle ore **18.30.**
📍 **Dove?** WeDesk (via Magenta 54, ingresso via Ballerini)
*👉 Un'esperienza* immersiva e innovativa\*, pensare per favorire **connessioni** tra i membri della **Community di Interconnection** e **professionisti e aziende**.\*

* why LLMs behave the way they do (hallucinations, prompt sensitivity, etc.)
* how people are building real systems with them today
* where things break in practice
This will be a **short, informal talk (\~15–20 min)** followed by open discussion and Q&A.
Whether you’re an engineer, builder, or just curious about how modern AI systems work, you’re welcome to join.
No slides, no fluff — just real conversation about real systems.
